Description

Delay unit, rope support, and horizontal blinds

The present invention relates to a delay unit for a rope supporting member capable of performing lifting and tilting operation of a blade through a single drive shaft, a rope supporting device, and a horizontal blind having both of them.

The horizontal louver can adjust the amount of sunlight entering the room by using the hoisting rope to raise or lower the plurality of blades supported by the directional control rope suspended from the upper beam.

For example, a lower beam is disposed at a lower end of the direction control rope, and the lower beam is raised or lowered by introducing the lifting rope attached to the lower beam into the upper beam or from the upper beam to raise or lower the lower beam. .

However, as one of the horizontal blinds, it is known to generally use a rope supporting member capable of performing a rotating operation of the inclined drum and the winding shaft through a drive shaft, wherein the inclined drum suspension supports the direction control rope, and the winding shaft is capable of Suspend or unwind the suspension support rope.

In the above-described conventional rope supporting member capable of performing the rotating operation of the inclined drum and the winding shaft through a drive shaft, even if it is not desired to raise or lower the blade due to the tilting operation, the tilting operation is performed. The lower beam rises or falls. In particular, in the case where the lower beam is not at the lower limit position, when the tilting operation is performed, the folded portion of the blade is inclined after rising, and there is a problem that it should be improved from the viewpoint of operability.

Therefore, for the rope supporting member, a technique is disclosed in which the inclined drum and the winding shaft are engaged with each other through the respective projections in a state in which the idle gap is provided, thereby delaying the rotation of the winding shaft with respect to the rotation of the inclined drum ( For example, refer to Patent Document 1).

More specifically, in the rope supporting member (mechanism storage box) in the technique of Patent Document 1, the inclined drum (rotating inclined drum) is directly coupled to the drive shaft so as to rotate together with the rotation of the drive shaft, and Newly set the shaft part (bushing) and secure it to the rope support. One end of the shaft member is provided with a brake drum and a clutch ring, and is disposed between the inclined drum and the winding shaft (lifting drum). Further, the winding shaft is slidably engaged with the peripheral edge of the cylindrical portion of the shaft member projecting from the brake drum, and is engaged with the inclined drum through the respective projections so as to rotate together by 180 degrees. Therefore, since the winding shaft is not directly coupled to the drive shaft, a certain amount of idling can be generated between the inclined drum and the winding shaft, and the rotation of the winding shaft can be delayed.

Further, as one form of the rope supporting device, the directional control rope is suspended by the upper end portion of the directional control rope and is hung on the inclined drum, so that the directional control rope is traversed by the rotation of the inclined drum. The supported blades rotate. In the form of the rope supporting device, in order to convert the rotation of the inclined drum into the movement of the direction control rope, it is necessary to generate a predetermined frictional resistance between the inclined drum and the annular upper end portion of the direction control rope. Therefore, a technique of providing a friction member on a part of the annular upper end portion of the direction control rope is known (for example, refer to Patent Document 2). [Prior Technical Literature] [Patent Literature]

Patent Document 1: Japanese Patent Laid-Open No. Hei 3-161685. Patent Document 2: Japanese Patent Publication No. Sho 39-12438

As described above, in the ordinary rope supporting member capable of performing the rotating operation of the inclined drum and the winding shaft through one drive shaft, there is a problem from the viewpoint of operability that even if it is not desired because of the tilting operation In the case where the blade is raised or lowered, the lower beam is also raised or lowered due to the tilting operation, or, in the case where the lower beam is not at the lower limit position, the folded portion of the blade is inclined after rising when the tilting operation is performed.

Further, although the technique of Patent Document 1 can solve the problem, the technique of Patent Document 1 is configured to allow the inclined drum and the winding shaft to transmit their respective protrusions in order to delay the rotation of the winding shaft with respect to the rotation of the inclined drum. The part is engaged in such a manner that an idle gap is provided. Therefore, when a plurality of rope supporting members or the like are provided in the upper beam, it is expected that the ropes need to be assembled repeatedly several times in order to align the rope supporting members with respect to one driving shaft (adjustment of the blade angle or adjustment of the rope length). The support member is adjusted, and the relative positional relationship between the inclined drum and the winding shaft is adjusted each time, so that the assembly into the upper beam is poor.

Further, in the technique of Patent Document 1, since the winding shaft is idly engaged with the peripheral edge of the tubular portion of the shaft member, it is difficult to downsize, and the rope support member may have a large diameter as a whole. The cost of the rope support member or the horizontal blinds is increased.

Further, in the technique of Patent Document 1, only the configuration in which the retardation angle is 180 degrees is disclosed, so that when it is applied to applications other than 180 degrees, at least the shape of the inclined drum, the winding shaft, and the clutch ring needs to be changed, and it is necessary to The use of the horizontal blinds prepares a rope supporting member having different shapes of the inclined drum, the winding shaft, and the clutch ring, thereby causing an increase in cost.

Further, in the technique of Patent Document 1, when it is desired to adjust or change the retardation angle at the time of assembly, the entire rope supporting member is also replaced. Therefore, there is a possibility that the burden of component management increases.

Therefore, it is desirable to obtain a rotating operation of the tilting drum and the winding shaft through a single drive shaft, and solve the following two problems, and contribute to improvement in assembly, miniaturization, generalization, and reduction in component management burden, and The low-cost and practical technology, the above two problems mean that even if the blade is not expected to rise or fall due to the tilting operation, the lower beam may rise or fall due to the tilting operation. And the problem that the folded portion of the blade is inclined after rising when the lower beam is not at the lower limit position.

Further, the upper end portion of the direction control rope is formed in a ring shape and attached to the inclined drum, so that the direction control rope is suspended, and the rope supported by the horizontal rope of the direction control rope is rotated by the rotation of the inclined drum. In the form of the supporting device, in the technique of providing the friction member with respect to the direction control rope as shown in Patent Document 2, since the friction member changes between the contact and non-contact states due to the rotation of the inclined roller, it is possible The contact of the friction member with the inclined roller becomes insufficient due to the swing of the direction control rope or the like, resulting in poor blade rotation.

The present invention has been made in view of the above problems, and an object thereof is to provide a delay unit, a rope supporting device, and a rope supporting member that can perform a lifting and tilting operation of a blade through a drive shaft in a form that is excellent in practicality.

The rotation intermediate plate 59 passes through an arrangement state in which the inner end surface of the rotation intermediate plate 59 abuts against the end surface of the output shaft member 56 (refer to (b) in FIG. 2) to be relatively rotatable. The method is housed in the housing portion 555 of each of the case members 55a and 55b. Therefore, the protruding piece 592 on the front end side of the rotating intermediate plate 59 can be relatively rotated within the range of the recessed portion other than the protruding portion 564 of the output shaft member 56, that is, the engaging receiving portion 563, that is, even if the rotating intermediate plate 59 is performed Rotation, before the protruding piece 592 abuts against the protruding portion 564 of the output shaft member 56 via the end portion 571 of the brake spring 57, the rotation of the rotating intermediate plate 59 is also not transmitted to the output shaft member 56, but in the protrusion After the piece 592 abuts against the protrusion 564 of the output shaft member 56, the rotation of the rotation intermediate plate 59 is transmitted to the output shaft member 56.

Further, a groove-shaped engagement receiving portion 593 is formed in addition to a part of the rotation receiving portion 594 around the end surface of the rotating intermediate plate 59 and around the shaft hole 591. The rotation receiving portion 594 is formed in a range of a predetermined angle (an angle α3 to be described later) with respect to the axial center of the shaft hole 591. In this example, the engagement receiving portion 593 is formed in a groove shape in order to form the rotation receiving portion 594. However, the groove receiving portion 593 may not be formed as long as it can perform the same function.

The input shaft member 60 is formed with a cylindrical shaft portion 601 and a protruding piece 603 via a flange portion 604, wherein the shaft portion 601 is directly coupled to the drive shaft 11 and has a substantially rectangular hole-shaped shaft hole 602, and the protruding piece 603 is The shaft portion 601 is protruded in parallel with a predetermined angle (the angle α4 to be described later) with respect to the axial center of the shaft portion 601, and a cylindrical shaft portion 606 is formed in the flange portion 604. The shaft portion 606 of the input shaft member 60 and the flange portion 604 are in an arrangement state in which the drive transmission output side surface of the flange portion 604 of the input shaft member 60 abuts against the drive transmission input side surface of the rotary intermediate plate 59 (refer to FIG. 2 (b)), the circular opening 559d and the accommodating portion 555 which are supported by the drive transmission input side end portions of the case members 55a and 55b, respectively, are relatively rotatable. Further, the shaft portion 601 can support the shaft hole 565 of the output shaft member 56 and the shaft hole 591 of the rotating intermediate plate 59.

Therefore, the protruding piece 603 of the input shaft member 60 can be relatively rotated within the range of the engaging receiving portion 593 of the rotating intermediate plate 59, that is, even if the input shaft member 60 directly coupled to the drive shaft 11 is rotated, it is protruded Before the piece 603 abuts against the rotation receiving portion 594 of the rotating intermediate plate 59, the rotation of the input shaft member 60 is not transmitted to the rotating intermediate plate 59, but the protruding piece 603 and the rotating receiving portion of the rotating intermediate plate 59 are provided. After the abutment 594, the rotation of the input shaft member 60 is transmitted to the rotating intermediate plate 59.

Therefore, the delay unit 5a of Embodiment 1 generates a delay amount before the rotation of the input shaft member 60 is transmitted to the output shaft member 56, which is the amount of delay between the input shaft member 60 and the rotating intermediate plate 59 and the rotation. The sum of the delay amounts between the rotating plate 59 and the output shaft member 56.

For example, as shown in (a) of FIG. 5, the amount of retardation between the rotating intermediate plate 59 and the output shaft member 56 is such that the protruding portion 564 protruding in the range of the angle α1 and protruding in the range of the angle α2 The amount of retardation β between the protruding pieces 592. For example, if α1≈60 degrees and α2≈90 degrees, the delay amount β≈210 degrees. Further, as shown in (b) of FIG. 5, the retardation amount between the input shaft member 60 and the rotation intermediate plate 59 is the rotation receiving portion 594 in the range of the angle α3 and the protrusion protruding in the range of the angle α4. The amount of delay γ between slices 603. For example, if α3≈60 degrees and α4≈60 degrees, the delay amount γ≈240 degrees. Further, the amount of delay until the rotation of the input shaft member 60 is transmitted to the output shaft member 56 is β + γ ≈ 450 degrees. Therefore, by setting the rotation delay amount generated by the delay unit 5a to be equal to or larger than the angle adjustment range of the blade 4, various delay amounts can be realized, and the rotation intermediate plate 59 functions as a delay adjustment member that transmits rotation with a predetermined delay amount. effect.

Further, in the components of the delay unit 5a of the first embodiment, the member that is directly coupled to the drive shaft 11 and rotates therewith has only the input shaft member 60, and the delay unit 5a of the first embodiment is arranged side by side on the drive shaft 11. Then, the winding shaft 52 can be rotated in association with the rotation of the inclined drum 51 by a predetermined delay amount via the obstacle detection stopping device 53 (refer to (b) of FIGS. 4 and 2).

In particular, as shown in FIG. 4, the housing members 55a, 55b of the delay unit 5a of the first embodiment are respectively formed with claw portions 558 on the side wall portions on the drive transmission output side, which grip the support of the rope support units 5b. A projection 50b is provided on the housing 50. Thereby, the delay unit 5a of the first embodiment can be stably assembled to the rope supporting unit 5b on the drive shaft 11 in a form that can be easily attached and detached. Further, by engaging the shaft portion 561 of the output shaft member 56 of the delay unit 5a with the shaft hole 531a of the cam shaft 531 of the obstacle detecting and stopping device 53, the delay unit 5a and the obstacle detecting and stopping device 53 can be integrated. The rotation is connected, but although the obstacle detecting stop device 53 functions to apply an excessive load to the rotation of the drive shaft 11, an undesired force for causing the obstacle detecting and stopping device 53 to be disengaged from the support housing 50 is generated. Undesirable forces that cause the connection state to separate may also occur, and thus may cause malfunction. Therefore, as shown in FIG. 4, it is preferable that the support housing 50 is provided with a suppression wall 50j for suppressing the upward movement of the cam shaft 531 so as to alleviate the separation of the connection state caused by the excessive load. The force of hope.

Further, the rotation of the rotation intermediate plate 59 may be omitted, and the input shaft member 60 and the output shaft member 56 may be directly coupled to each other, so that only a delay amount is generated between the input shaft member 60 and the output shaft member 56, whereby the same can be shared. The output shaft member 56, the brake spring 57, the spring case 58, and the input shaft member 60 generate different amounts of retardation. This case will be described later as the second embodiment.

For example, as shown in (c) of FIG. 5, the amount of retardation between the input shaft member 60 and the output shaft member 56 when the rotary intermediate plate 59 is not used is: the protrusion 564 protruding in the range of the angle α1 and The amount of retardation η between the protruding protrusion pieces 603 in the range of the angle α4. For example, if α1≈60 degrees and α4≈60 degrees, the delay amount η≈240 degrees. Therefore, by setting the amount of rotation delay generated by the delay unit 5a to be equal to or larger than the angle adjustment range of the blade 4, various delay amounts can be realized.

Further, the shape of the projection piece 592 (angle α2) or the shape of the rotation receiving portion 594 (angle α3) is different, and a plurality of retardation amounts of the rotation of the rotation plate 59 can be generated, and only a plurality of rotations of the rotation plate 59 can be realized. The amount of delay.

The case members 55a, 55b are formed to be fitted to each other in a direction perpendicular to the drive shaft 11 (in the front-rear direction in this example), thereby accommodating the output shaft member 56, the brake spring 57, the spring case 58, and the rotary intermediate plate 59 and the input shaft member 60. More specifically, a fitting receiving portion 551 having a protruding portion 553 is formed on each of the top surface and the bottom surface of the case member 55a, and a fitting piece 552 is formed on the top surface and the bottom surface of the case member 55b, respectively. The fitting piece 552 is engaged with the fitting receiving portion 551 and has a hole portion 554 that can be fitted to the protruding portion 553. In other words, when one case is formed by inserting and fitting two case members, if the housing is formed in a direction parallel to the drive shaft 11, the fitting force is weakened by the rotation of the drive shaft 11, thereby There is a possibility that a quality problem may occur, and thus it is necessary to form the whole by a screw or the like. However, it is configured to be fitted in a direction perpendicular to the drive shaft 11 as in the present embodiment, and has an insertion capable of withstanding the rotation of the drive shaft 11. Together, it is not necessary to form a whole with screws or the like, which in general helps to improve assembly and reduce costs.

Further, in the present embodiment, the shaft portion 561 of the output shaft member 56 and the shaft hole 531a of the cam shaft 531 of the obstacle detecting and stopping device 53 are engaged in a hexagonal shape, but the assemblability is improved. From the viewpoint of the above, the shape of the engagement formed into more sides is better. In other words, the shaft portion 561 of the output shaft member 56 is formed in a polygonal shape, and the shaft hole 531a of the cam shaft 531 of the obstacle detecting and stopping device 53 is configured to be engaged with the shaft portion 561 of the output shaft member 56. This can be assembled by a minute rotation operation, and the assembly property is improved.

Further, the horizontal louver applied to the rope supporting device 5 having the delay unit 5a of the first embodiment shown in Fig. 1 is configured such that the rotation of the inclined drum 51 and the winding shaft 52 can be performed through one drive shaft 11, but When the blade 4 is not raised or lowered due to the tilting operation, the lower beam 8 is not raised or lowered by the tilting operation. Further, in the case where the lower beam 8 is not at the lower limit position, the lossy operability in which the folded portion of the blade 4 is inclined after rising does not occur even when the tilting operation is performed.

For example, in the case where the stationary state and the horizontal state of the blades 4 shown in (a) of FIG. 6 are stacked on the lower beam 8 by a prescribed number, even if the blade is adjusted by the tilting operation as shown in (b) of FIG. At the angle of 4, the lower beam 8 will not rise or fall. Further, as shown in (c) of FIG. 6, when the tilting operation is performed, the lossy operability such that the folded portion of the blade 4 is raised and then tilted does not occur.

Further, as shown in FIG. 3, the housing members 55a and 55b are formed with an upper corner portion 550a which is recessed in a quadrangular shape. Therefore, when the delay unit 5a is disposed in the upper beam 1, the upper corner portion 550a of the delay unit 5a supported by the lower corner portion 550b is engaged with the upper end of the upper beam 1, respectively (refer to FIG. 6), so that the delay unit 5a can be suppressed. Shake in the front and rear direction and the up and down direction. Further, since the claw portions 558 are formed in the case members 55a and 55b of the delay unit 5a, the claw portions 558 can be prevented from being delayed by the protrusions 50b on the support case 50 of the string supporting unit 5b. The unit 5a is shaken in the left and right direction.

In the present embodiment, the example in which the shaft portion 561 of the output shaft member 56 is engaged with the shaft hole 531a of the cam shaft 531 of the obstacle detection stopping device 53 has been described. However, it is formed as the output shaft member 56. When the shaft portion 561 is directly engaged with the winding shaft 52 without passing through the obstacle detecting and stopping device 53, the action and effect of the present invention can be exhibited.

(Embodiment 2) Next, a rope supporting device 5 having the delay unit 5a of the second embodiment will be described. (a) and (b) of Fig. 7 are respectively a perspective view and a cross-sectional view showing a schematic configuration of a cord supporting device 5 having a delay unit 5a according to a second embodiment of the present invention. Fig. 8 is an exploded perspective view showing a schematic configuration of a delay unit 5a according to a second embodiment of the present invention. In addition, FIG. 9 is a perspective view illustrating a method of assembling the string supporting device 5 having the delay unit 5a according to the second embodiment of the present invention. In the second embodiment, constituent elements having the same functions as those of the first embodiment are denoted by the same reference numerals.

The rope supporting device 5 having the delay unit 5a of the second embodiment shown in Fig. 7(a) is configured by arranging the delay unit 5a and the rope supporting unit 5b in parallel as in the first embodiment. Further, in the rope supporting unit 5b provided in parallel with the delay unit 5a of the second embodiment, as in the first embodiment, the inclined drum 51 and the winding shaft 52 are rotated by the support housing 50 so that the drive shaft 11 can be rotated. Support. The direction control rope 9 suspended from the inclined drum 51 and the lift cord 10 suspended from the winding shaft 52 are taken out from the guide opening 50a provided on the bottom surface of the support casing 50.

However, the winding shaft 52 of the rope supporting unit 5b provided in parallel with the delay unit 5a of the second embodiment can wind the belt-shaped lifting/lowering cord 10 in a plurality of layers, or can be unwound, and the inclined drum 51 can be mounted through The directional control rope 9 is suspended by a suspension member 511 formed by a torsion coil spring. The configuration of the above-described rope supporting unit 5b is suitable for a horizontal blind which is required to be miniaturized.

The suspension member 511 is composed of a torsion coil spring, and both ends of the torsion coil spring are bent to form an annular direction control cord fixing portion 511a and a locking end portion 511b. The upper ends of the pair of front and rear direction control cords 9 are fixed to the direction control cord fixing portion 511a and are suspended and supported. Further, the suspension member 511 is tightly wound and fixed to the inclined drum 51, and the suspension member 511 and the inclined drum 51 integrally rotate before the locking end portion 511b abuts against the wall portion formed on the support casing 50. When the locking end portion 511b abuts against the wall portion formed on the support housing 50, the fastening force thereof becomes weak and idling with respect to the inclined drum 51. Therefore, the angle of each of the blades 4 can be adjusted in phase by the rotation of the inclined drum 51 via the direction control rope 9.

The delay unit 5a of the first embodiment shown in FIG. 3 can also be used with respect to the rope supporting unit 5b provided in parallel with the delay unit 5a of the second embodiment. However, in order to achieve the object of miniaturization, the delay unit of the second embodiment 5a is constructed as shown in FIG.

Referring to Fig. 8, in comparison with the first embodiment, the delay unit 5a of the second embodiment omits the rotary intermediate plate 59 to miniaturize the shape of the housing members 55a, 55b, and other output shaft members 56, brake springs 57, and springs. The housing 58 and the input shaft member 60 are common to the first embodiment.

Further, the shape of the case members 55a and 55b is such that the housing portion 555 accommodating the rotary intermediate plate 59 is not formed as compared with the first embodiment, and the shaft portion 606 and the flange portion 604 of the input shaft member 60 are respectively rotatable relative to each other. The manner of supporting the circular opening portion 559d and the opening side surface 559b on the drive transmission input side end portions of the housing members 55a, 55b contributes to miniaturization, and other effects and embodiments are in addition to this. 1 is the same.

That is, the delay unit 5a of the second embodiment is configured such that the rotation of the rotation of the intermediate plate member 60 and the output shaft member 56 are directly connected, thereby causing a delay amount only between the input shaft member 60 and the output shaft member 56. Further, the same output shaft member 56, brake spring 57, spring case 58, and input shaft member 60 are shared as in the first embodiment, but different delay amounts can be generated.

For example, as described above with reference to (c) of FIG. 5, the amount of delay between the input shaft member 60 and the output shaft member 56 when the rotary intermediate plate 59 is not used is: the protrusion 564 protruding in the range of the angle α1 The amount of retardation η between the protrusions 603 protruding in the range of the angle α4. For example, if α1≈60 degrees and α4≈60 degrees, the delay amount η≈240 degrees. Therefore, by setting the amount of rotation delay generated by the delay unit 5a to be equal to or larger than the angle adjustment range of the blade 4, various delay amounts can be realized.

Further, in the second embodiment, as shown in (b) of FIG. 7, the inclined drum 51 is also coupled to the drive shaft 11 so as not to be relatively rotatable, and is supported in the support housing 50. Further, the winding shaft 52 is supported in the support housing 50 in a state of being uncoupled (not engaged) with the drive shaft 11. Further, the front end side of the winding shaft 52 is provided with an obstacle detecting and stopping device 53 for preventing the winding shaft supporting the lifting rope 10 from being applied to the lifting rope 10 in the direction of the pulling-out direction. The rotation of 52 is performed, and the obstacle detection stopping device 53 is also supported in the support housing 50 in a state of being uncoupled (not engaged) with the drive shaft 11. The outer casing main body of the obstacle detection stopping device 53 is fixed to the front end side of the winding shaft 52, and the cylindrical cam shaft 531 of the obstacle detecting and stopping device 53 housed in the outer casing main body can be integrally formed with the winding shaft 52. Rotating, and having the lower beam 8 hitting the obstacle during the lowering of the blade 4, stopping the lifting rope 10 to stop the blade 4 and the lower beam 8 from falling, and preventing the lifting rope 10 from being reversely wound Idle gap.

Further, in the delay unit 5a of the second embodiment, the member that is directly coupled to the drive shaft 11 and rotates therewith has only the input shaft member 60, and as long as the delay unit 5a of the second embodiment is arranged side by side on the drive shaft 11, The winding shaft 52 can be rotated in association with the rotation of the inclined drum 51 by a predetermined delay amount via the obstacle detection stopping device 53 (refer to (b) of FIGS. 9 and 7).

In particular, as shown in FIG. 9, the housing members 55a and 55b of the delay unit 5a of the second embodiment are respectively formed with claw portions 558 on the side wall portions on the drive transmission output side, and the claw portions 558 are gripped and disposed on the rope supporting unit 5b. The protrusion 50b on the support case 50. Thereby, the delay unit 5a of the second embodiment can be stably assembled to the rope supporting unit 5b on the drive shaft 11 in an easily detachable manner.

Further, in the second embodiment, the case members 55a and 55b are also configured to be fitted in a direction perpendicular to the drive shaft 11, and have a fitting force capable of withstanding the rotation of the drive shaft 11, so that it is not required to be formed by a screw or the like. Overall, in general, it helps to improve assembly and reduce costs.

Further, as shown in Fig. 8, in the second embodiment, the upper corner portions 550a which are recessed in a quadrangular shape are also formed in the case members 55a and 55b. Therefore, when the delay unit 5a is disposed in the upper beam 1, the upper corner portion 550a of the delay unit 5a supported by the lower corner portion 550b is engaged with the upper end of the upper beam 1 (the same as FIG. 6 described above), thereby suppressing the delay. The unit 5a is shaken in the front-rear direction and the up-and-down direction. Further, since the claw portions 558 are formed in the case members 55a and 55b of the delay unit 5a, the claw portions 558 can be prevented from being delayed by the protrusions 50b on the support case 50 of the string supporting unit 5b. The unit 5a is shaken in the left and right direction.

Further, in the present embodiment, the shaft portion 561 of the output shaft member 56 is also formed in a polygonal shape, and the cam shaft 531 of the obstacle detecting and stopping device 53 is configured to be engageable with the shaft portion 561 of the output shaft member 56. The shaft hole 531a can be assembled by a small rotation operation, and the assembly property is improved.

Further, in the case of the horizontal louver to which the rope supporting device 5 having the delay unit 5a of the second embodiment is applied, even in the case where the rotation of the inclined drum 51 and the winding shaft 52 is performed by being able to pass through one drive shaft 11, When it is not desired to raise or lower the blade 4 due to the tilting operation, the lower beam 8 is not raised or lowered by the tilting operation. Further, in the case where the lower beam 8 is not at the lower limit position, the lossy operability in which the folded portion of the blade 4 is inclined after rising does not occur even when the tilting operation is performed.

In the present embodiment, the example in which the shaft portion 561 of the output shaft member 56 is engaged with the cam shaft 531 of the obstacle detection stopping device 53 has been described. However, the shaft portion 561 formed as the output shaft member 56 is formed. When the knitting shaft 52 is directly engaged with the obstacle detecting device 53 without passing through the obstacle detecting device 53, the actions and effects of the present invention can be exhibited.

Further, the delay unit 5a of the first and second embodiments can be applied to the rope supporting unit 5b for winding the rope-like lifting cord 10 by the spirally wound screw shaft 52C while maintaining the shape and structure thereof, thereby constituting the rope support. Device 5.

For example, (a) and (b) of Fig. 10 are respectively a perspective view and a cross-sectional view showing a schematic configuration of a spirally wound rope supporting device 5 having a delay unit 5a according to a second embodiment of the present invention. In addition, FIG. 11 is a perspective view illustrating a method of assembling the spirally wound rope supporting device 5 having the delay unit 5a according to the second embodiment of the present invention. In addition, in FIGS. 10 and 11, constituent elements having the same functions as those of the first embodiment are denoted by the same reference numerals.

The spirally wound rope supporting device 5 shown in Fig. 10(a) is configured by transmitting the delay unit 5a and the rope supporting unit 5b in parallel as described above. However, a spiral screw ridge is formed on the surface of the screw shaft 52C in the rope supporting unit 5b shown in (a) of FIG. 10, and the drive shaft 11 passes through the non-engaged (non-joined) state. The substantially cylindrical main body, the upper end of the lifting cord 10 is fixed in the concave portion near the front end of the screw shaft 52C, so that the winding and unwinding of the lifting cord 10 can be performed.

The spirally-shaped spiral ridge of the screw shaft 52C can be screwed with the spiral-shaped screw-like ridge 50d provided on the inner circumferential surface of the support housing 50, and rotates with the screw shaft 52C (winding shaft 52). The screw shaft 52C itself moves in the axial direction relative to the casing portion 51C thereof.

An inclined drum 51 is formed on the casing portion 51C, and the inclined drum 51 is suspended from the supporting direction control rope 9 by attaching a suspension member 511 composed of a torsion coil spring.

The suspension member 511 forms an annular direction control cord fixing portion 511a and a locking end portion 511b by bending both ends of the torsion coil spring, and the suspension member 511 is tightly wound and fixed to the inclined drum 51. Further, before the locking end portion 511b abuts against the wall portion formed on the support housing 50, the suspension member 511 integrally rotates with the inclined drum 51, and when the locking end portion 511b is formed on the support housing 50 When the wall portion abuts, the fastening force of the suspension member 511 becomes weak and idling with respect to the inclined drum 51. Therefore, the angle of each of the blades 4 can be adjusted in phase by the rotation of the inclined drum 51 via the direction control rope 9.

In the example shown in (a) of FIG. 10, the inclined drum 51 and the winding shaft 52 are also supported by the support casing 50 so as to be rotatable about the drive shaft 11 as a rotating shaft. The direction control rope 9 suspended from the inclined drum 51 and the lift cord 10 suspended from the winding shaft 52 are taken out from the guide opening 50a provided on the bottom surface of the support casing 50.

Further, as shown in (b) of FIG. 10, the casing portion 51C (inclined drum 51) is coupled to the drive shaft 11 so as not to be relatively rotatable, and is supported in the support casing 50. Further, the winding shaft 52 is supported in the support housing 50 in a state of being uncoupled from the drive shaft 11.

Further, as shown in (a) and (b) of FIG. 10, the delay unit 5a of the second embodiment is configured to be supported by a disk-shaped support fixed to the front end of the screw shaft 52C (winding shaft 52). The component 70 is mounted.

In the delay unit 5a of the second embodiment, the member directly coupled to the drive shaft 11 and rotated therewith has only the input shaft member 60, and as long as the delay unit 5a of the second embodiment is arranged side by side on the drive shaft 11, the spiral can be made The shaft 52C (winding shaft 52) is rotated in association with the rotation of the inclined drum 51 by a predetermined retard amount (refer to (b) of FIGS. 11 and 10).

In particular, as shown in Fig. 11, the claw portions 558 of the casing members 55a, 55b of the delay unit 5a of the second embodiment can grip the disc-shaped plate provided on the screw shaft 52C (winding shaft 52) of the rope supporting unit 5b. Supporting support 70. Thereby, the delay unit 5a of the second embodiment can be stably assembled on the drive shaft 11 in a form of easy attachment and detachment on the spiral rope support unit 5b.

[Other Embodiments] In the delay unit 5a of the above-described first and second embodiments, the rope supporting device 5 is configured by arranging the delay units 5a side by side on the outer sides of the various support housings 50, thereby improving the assemblability and facilitating the assembly. The reduction in the size and generalization of the rope supporting device 5, the reduction in the component management burden, and the reduction in cost have been described, and the practicality is excellent. In particular, in the delay unit 5a of the first and second embodiments, attention is paid to contributing to the reduction of the component management burden and the reduction in the cost, thereby increasing the number of shared components as much as possible.

Since the enlargement of the rope supporting device 5 in the front-rear direction or the vertical direction also causes the shielding device itself to become large, the delay unit 5a of the first and second embodiments can avoid the enlargement, thereby producing an effective effect. effect.

In addition, comparing the delay unit 5a of the embodiment 1 shown in FIG. 3 with the delay unit 5a of the embodiment 2 shown in FIG. 8, it can be seen that the embodiment 1 shown in FIG. 3 is compared with the delay unit 5a of the second embodiment. The housing members 55a and 55b of the delay unit 5a have a large width in the left-right direction. Therefore, when the installation space in the upper beam 1 is insufficient, for example, it is desirable to further reduce the width in the left-right direction of the case members 55a and 55b of the delay unit 5a of the first embodiment.

Therefore, as a configuration example in which the size of the delay unit 5a itself is further reduced in size as compared with the reduction of the component management burden and the reduction in cost, the third and fourth embodiments will be sequentially described below. . In short, the first and second embodiments are configured to include a rotation transmission portion having a predetermined retardation amount in the axial direction of the drive shaft 11, and in the third and fourth embodiments, the transmission is configured to include the direction perpendicular to the drive shaft 11 The rotation transmission portion of the delay amount is defined so that the widths of the casing members 55a and 55b of the delay unit 5a of the third and fourth embodiments are smaller in the left-right direction.

(Embodiment 3) FIG. 12 is an exploded perspective view showing a schematic configuration of a delay unit according to Embodiment 3 of the present invention. In addition, constituent elements having the same functions as those of the above-described first embodiment are denoted by the same reference numerals. As shown in Fig. 12, the delay unit 5a of the present embodiment includes the output shaft member 56, the brake spring 57, the spring case 58, the rotary intermediate plate 59, the input shaft member 60, and the housing member 55a as in the first embodiment. 55b.

The output shaft member 56 of the present embodiment has a cylindrical shaft portion 561 having an octagonal outer shape and a projection portion 564 provided on the shaft via a flange portion 567 formed with a cylindrical shaft portion 568. The end portion of the portion 561 (the drive transmission input side) is provided to the flange portion 567 so as to protrude toward the drive transmission input side in a range of a predetermined angle (the angle α1 to be described later) with respect to the axial center of the flange portion 567. Partially near the perimeter. The shaft portion 568 and the flange portion 567 of the output shaft member 56 are supported on the circular opening portion 559c and the opening side surface 559a of one side surface (drive transmission output side) of the housing members 55a and 55b so as to be rotatable relative to each other. Further, in the output shaft member 56 of the present embodiment, the engagement receiving portions 563a and 563b which are recessed in a stepped manner are formed on the surface of the end portion (drive transmission input side) of the flange portion 567. Further, a shaft hole 565 is formed in the shaft portion 561, and the drive shaft 11 can pass through the shaft hole 565 in a non-engaged manner. Further, the cylindrical shaft portion 561 having the octagonal outer side and the cylindrical cam shaft 531 having the octagonal shaft hole 531a of the obstacle detecting and stopping device 53 are engaged to be integrally rotatable, thereby enabling the output shaft The rotation of the member 56 is transmitted to the cam shaft 531 of the obstacle detecting and stopping device 53 in the synchronous rotation (the same as (b) in Fig. 2 described above).

The diameters of the brake spring 57 and the spring case 58 are larger than the diameters of the brake spring 57 and the spring case 58 in the first and second embodiments, so that the rotary intermediate plate 59 of the present embodiment described later is housed inside, but can be combined with the above. In the same manner, the first and second embodiments function as a brake member that suppresses rotation other than the rotation transmitted from the input shaft member 60, for example, from the rotation of the output shaft member 56. That is, a predetermined braking force is generated for the rotation transmitted from the cam shaft 531 of the obstacle detection stopping device 53 to the output shaft member 56. In order to stabilize the winding shaft 52 when the lifting operation is not performed, in order to stably maintain the lifting position of the blade 4, one end portion 571 of the coil-shaped brake spring 57 is respectively engaged and fixed to the output shaft member 56. On both sides of the protrusion 564. Further, the coil-shaped brake spring 57 is housed in the spring case 58 in a reduced diameter state, whereby since the brake spring 57 always presses the inner peripheral surface of the spring case 58, the brake spring 57 can be opposed to the spring The housing 58 rotates but generates a predetermined braking force. Further, the spring case 58 is fitted and fixed to the case member 55a so that the pair of recessed portions 582 provided on a part thereof are engaged with the projections 557 provided on the case members 55a and 55b, respectively, so as not to be rotatable. In the respective accommodating portions 556 of the 55b, the spring case 58 is fixed in a state in which it cannot rotate.

The rotary intermediate plate 59 of this embodiment is largely different from the above-described first embodiment. The rotary intermediate plate 59 of the present embodiment is composed of a substantially cylindrical member having an outer diameter smaller than the diameter of the brake spring 57 housed in the spring case 58 in a reduced diameter state, and has a projection 592a on one of the outer peripheral faces. A rotation receiving portion 594 is provided on one of the inner circumferential surfaces, and a shaft hole 591 having a diameter substantially equal to the diameter of the shaft hole 565 of the output shaft member 56 is formed in the rotation intermediate plate 59. Therefore, the drive shaft 11 can pass through the shaft hole 591 in a non-engaged state. The drive transmission output side surface of the rotary intermediate plate 59 has a shape that can pass through the inner side of the brake spring 57 and abuts against the engagement receiving portions 563a and 563b of the drive transmission input side surface of the output shaft member 56, and is abutted at the abutment In the disposition state, the rotation intermediate plate 59 is placed inside the brake spring 57 housed in the spring case 58 in a reduced diameter state, and is housed in the case members 55a, 55b so as to be rotatable relative thereto. Therefore, the projection 592a of the rotation intermediate plate 59 is relatively rotatable within a range of the recessed portion other than the projection 564 of the output shaft member 56, that is, the engagement receiving portion 563b, that is, even if the rotary intermediate plate 59 is rotated, Before the protruding portion 592a abuts against the protruding portion 564 of the output shaft member 56 via the end portion 571 of the brake spring 57, the rotation of the rotating intermediate plate 59 is not transmitted to the output shaft member 56, but in the protruding piece 592 and After the protrusion 564 of the output shaft member 56 abuts, the rotation of the rotation intermediate plate 59 is transmitted to the output shaft member 56.

Further, on the inner circumferential surface of the rotation intermediate plate 59, a concave engagement receiving portion 593 is formed around the shaft hole 591 in addition to a part of the rotation receiving portion 594. The rotation receiving portion 594 is formed in a range of a predetermined angle (an angle α3 to be described later) with respect to the axial center of the shaft hole 591. In the present example, the rotation receiving portion 594 and the projection portion 592a are formed in the same range of rotation angles. However, the size and arrangement of the rotation receiving portion 594 and the projection portion 592a may be changed depending on the application.

The input shaft member 60 has a cylindrical shaft portion 601 which is directly coupled to the drive shaft 11 and has a substantially rectangular hole-shaped shaft hole 602, and a projection piece 603 formed on the cylindrical shaft portion. The flange portion 604 of the 606 is transmitted on the output side surface, and protrudes in parallel with the shaft portion 601 in a range of a predetermined angle (the angle α4 to be described later) with respect to the axial center of the shaft portion 601. In a state in which the drive transmission output side surface of the flange portion 604 of the input shaft member 60 abuts against the end surface of the rotary intermediate plate 59, the shaft portion 606 and the flange portion 604 of the input shaft member 60 are respectively rotatable. The manner is supported in the circular opening portion 559d and the opening side surface 559b of the drive transmission input side end portion of the housing portion 556 of the housing members 55a, 55b. Further, the shaft portion 601 can support the shaft hole 565 of the output shaft member 56 and the shaft hole 591 of the rotating intermediate plate 59.

Therefore, the protruding piece 603 of the input shaft member 60 can be relatively rotated within the range of the engaging receiving portion 593 of the rotating intermediate plate 59, that is, even if the input shaft member 60 directly coupled to the drive shaft 11 is rotated, it is protruded Before the piece 603 abuts against the rotation receiving portion 594 of the rotating intermediate plate 59, the rotation of the input shaft member 60 is not transmitted to the rotating intermediate plate 59, but the protruding piece 603 and the rotating receiving portion of the rotating intermediate plate 59 are provided. After the abutment 594, the rotation of the input shaft member 60 is transmitted to the rotating intermediate plate 59.

Therefore, the delay unit 5a of Embodiment 3 generates the amount of delay between the input shaft member 60 and the rotating intermediate plate 59 and the rotating intermediate plate 59 and the output shaft before transmitting the rotation of the input shaft member 60 to the output shaft member 56. The amount of delay in the sum of the delays between components 56.

For example, as shown in (a) of FIG. 14, the amount of retardation between the rotating intermediate plate 59 and the output shaft member 56 is such that the protruding portion 564 protruding in the range of the angle α1 and protruding in the range of the angle α2 The amount of retardation β between the protrusions 592a. Further, as shown in (b) of FIG. 14, the retardation amount between the input shaft member 60 and the rotation intermediate plate 59 is such that the rotation receiving portion 594 within the range of the angle α3 protrudes in the range of the angle α4. The amount of retardation γ between the protruding pieces 603. Therefore, the amount of delay until the rotation of the input shaft member 60 is transmitted to the output shaft member 56 is β + γ. Therefore, the delay unit 5a of the present embodiment can realize the same function as the delay unit 5a of the first embodiment, and the rotary intermediate plate 59 functions as a delay adjustment member that rotates by a predetermined delay amount.

In particular, the delay unit 5a of the present embodiment is configured such that the rotary intermediate plate 59 is located inside the spring case 58 and housed in the case members 55a and 55b, so that the delay unit 5a of the first embodiment can be realized. The front-back direction and the up-and-down direction width are smaller than the delay unit 5a of the first embodiment.

Further, in the components of the delay unit 5a of the third embodiment, the member that is directly coupled to the drive shaft 11 and rotates therewith has only the input shaft member 60, and the delay unit 5a of the third embodiment is disposed side by side on the drive shaft 11. Then, the winding shaft 52 can be rotated in association with the rotation of the inclined drum 51 by a predetermined delay amount via the obstacle detecting and stopping device 53 (the same as FIG. 4 described above).

Further, in the present embodiment, claw portions 558 are also formed on the side wall portions on the drive transmission output sides of the housing members 55a, 55b, respectively, which grip the support housings 50 provided on the rope support unit 5b. The protrusion 50b. Thereby, the delay unit 5a of the third embodiment can be stably assembled to the rope supporting unit 5b on the drive shaft 11 in a form that can be easily attached and detached.

Further, in the horizontal louver to which the rope supporting device 5 having the delay unit 5a of the third embodiment is applied, when the blade 4 is not desired to be raised or lowered by the tilting operation, the lower beam 8 is not raised by the tilting operation. Or drop. Further, when the lower beam 8 is not at the lower limit position, the lossy operability in which the folded portion of the blade 4 is inclined after rising does not occur even when the tilting operation is performed (the same as FIG. 6 described above).

Further, as shown in Fig. 12, in the third embodiment, the upper corner portions 550a which are recessed in a quadrangular shape are also formed in the casing members 55a and 55b. Therefore, when the delay unit 5a is disposed in the upper beam 1, the upper corner portion 550a of the delay unit 5a supported by the lower corner portion 550b is engaged with the upper end of the upper beam 1 (the same as FIG. 6 described above), thereby suppressing the delay. The unit 5a is shaken in the front-rear direction and the up-and-down direction. Further, since the claw portions 558 are formed in the case members 55a and 55b of the delay unit 5a, the claw portions 558 can be prevented from being delayed by the protrusions 50b on the support case 50 of the string supporting unit 5b. The unit 5a is shaken in the left and right direction.

(Embodiment 4) Next, a rope supporting device 5 having the delay unit 5a of the fourth embodiment will be described. Fig. 13 is an exploded perspective view showing a schematic configuration of a delay unit according to a fourth embodiment of the present invention. In addition, constituent elements having the same functions as those of the above-described third embodiment are given the same reference numerals. As shown in Fig. 13, the delay unit 5a of the present embodiment includes the output shaft member 56, the brake spring 57, the spring case 58, the input shaft member 60, and the case members 55a and 55b, similarly to the above-described third embodiment.

Referring to Fig. 13, in comparison with the third embodiment, the delay unit 5a of the embodiment 4 keeps the shape of the casing members 55a, 55b small, and omits the rotating intermediate plate 59, with the input shaft member 60 being changed. The shape, other output shaft member 56, brake spring 57, and spring housing 58 are common to the third embodiment.

The input shaft member 60 of the delay unit 5a of the fourth embodiment includes a cylindrical shaft portion 601, a cylindrical intermediate shaft portion 605, and a protruding piece 603a, wherein the shaft portion 601 is directly coupled to the drive shaft 11 and has a substantially square hole. a shaft hole 602; the intermediate shaft portion 605 is connected to the end side of the shaft portion 601 and has a diameter larger than the shaft portion 601, and has a four-hole hole-shaped shaft hole 602; the protruding piece 603a is formed on the flange portion 604, and The central axis portion 605 protrudes in parallel with the central axis portion 605 in a range of a predetermined angle (an angle α5 to be described later) with respect to the axial center of the shaft portion 601 and the intermediate shaft portion 605.

The shaft portion 601 can support the shaft hole 565 of the output shaft member 56. Further, when the interface between the intermediate shaft portion 605 and the shaft portion 601 passes through the inside of the brake spring 57 and abuts against the engagement receiving portion 563a on the end surface of the output shaft member 56, the shaft portion 606 of the shaft member 60 is input. The flange portion 604 is supported by the circular opening portion 559d and the opening side surface 559b of the input side end portion of the housing portion 556 of the housing members 55a and 55b so as to be rotatable relative to each other. At this time, the intermediate shaft portion 605 is located inside the brake spring 57 housed in the spring case 58 in a reduced diameter state, and is housed in the case members 55a and 55b so as to be rotatable relative to each other.

Therefore, the protruding piece 603a of the input shaft member 60 can be relatively rotated within the range of the engaging receiving portion 563b on the end surface of the output shaft member 56, that is, even if the input shaft member 60 directly coupled to the drive shaft 11 rotates, the protrusion Before the piece 603a comes into contact with the protruding portion 564 of the output shaft member 56, the rotation of the input shaft member 60 is not transmitted to the output shaft member 56, and after the protruding piece 603a abuts against the protruding portion 564 of the output shaft member 56, The rotation of the input shaft member 60 is transmitted to the output shaft member 56.

Further, the shape of the case members 55a and 55b is also maintained in a form that contributes to further miniaturization, and the same operational effects as those of the third embodiment can be produced.

For example, as shown in (c) of FIG. 14, the amount of delay between the input shaft member 60 and the output shaft member 56 when the rotary intermediate plate 59 is not used is: the protrusion 564 protruding in the range of the angle α1 and The amount of retardation η between the protruding projection pieces 603a in the range of the angle α5.

Further, in the same manner as in the second embodiment (the same as (b) in Fig. 7 described above), the inclined drum 51 in the fourth embodiment is also coupled to the drive shaft 11 so as not to be relatively rotatable, and is supported by the support housing. 50. Further, the winding shaft 52 is supported in the support housing 50 in a state of being uncoupled (not engaged) with the drive shaft 11. Further, the front end side of the winding shaft 52 is provided with an obstacle detecting and stopping device 53 for preventing the winding shaft supporting the lifting rope 10 from being applied to the lifting rope 10 in the direction of the pulling-out direction. The rotation of 52 is performed, and the obstacle detection stopping device 53 is also supported in the support housing 50 in a state of being uncoupled (not engaged) with the drive shaft 11. The outer casing main body of the obstacle detection stopping device 53 is fixed to the front end side of the winding shaft 52, and the cylindrical cam shaft 531 of the obstacle detecting and stopping device 53 housed in the outer casing main body can be integrally formed with the winding shaft 52. Rotating, and having the lower beam 8 hitting the obstacle during the lowering of the blade 4, stopping the lifting rope 10 to stop the blade 4 and the lower beam 8 from falling, and preventing the lifting rope 10 from being reversely wound Idle gap.

Further, in the delay unit 5a of the fourth embodiment, the member that is directly coupled to the drive shaft 11 and rotates therewith has only the input shaft member 60, and as long as the delay unit 5a of the fourth embodiment is arranged side by side on the drive shaft 11, The winding shaft 52 can be rotated in association with the rotation of the inclined drum 51 by a predetermined delay amount via the obstacle detection stopping device 53 (the same as FIG. 9 described above).

Further, in the delay unit 5a of the fourth embodiment, claw portions 558 are formed on the side wall portions on the drive transmission output sides of the casing members 55a and 55b, respectively, and the claw portions 558 grip the support provided on the rope support unit 5b. A projection 50b on the housing 50. Thereby, the delay unit 5a of the fourth embodiment can be stably assembled to the rope supporting unit 5b in the form of easy attachment and detachment on the drive shaft 11.

Further, in the same manner as in the first and second embodiments, the delay unit 5a of the third and fourth embodiments can be applied to the rope supporting unit 5b that winds the string-shaped lifting cord 10 through the spirally wound screw shaft 52C, thereby constituting The rope supporting device 5 (see Fig. 10 described above). In particular, similarly to the above-described Fig. 11, the claw portions 558 of the casing members 55a and 55b of the delay unit 5a of the fourth embodiment can grip the screw shaft 52C (winding shaft 52) provided on the rope supporting unit 5b. A disk-shaped support auxiliary member 70. Thereby, the delay unit 5a of the fourth embodiment can be stably assembled to the screw-type rope supporting unit 5b on the drive shaft 11 in an easily detachable manner.

Further, as shown in Fig. 13, in the fourth embodiment, the upper corner portions 550a which are recessed in a quadrangular shape are also formed in the case members 55a and 55b. Therefore, when the delay unit 5a is disposed in the upper beam 1, the upper corner portion 550a of the delay unit 5a supported by the lower corner portion 550b is engaged with the upper end of the upper beam 1 (the same as FIG. 6 described above), thereby suppressing the delay. The unit 5a is shaken in the front-rear direction and the up-and-down direction. Further, since the claw portions 558 are formed in the case members 55a and 55b of the delay unit 5a, the claw portions 558 can be prevented from being delayed by the protrusions 50b on the support case 50 of the string supporting unit 5b. The unit 5a is shaken in the left and right direction.

(Assembly structure of the delay unit in the upper beam) Fig. 15 is a plan view showing a configuration in which the delay unit 5a according to the embodiment of the present invention is incorporated in the upper beam 1. In particular, in FIG. 15, the delay unit 5a shown in FIG. 13 in the delay unit 5a of the above-described first to fourth embodiments is taken as a representative example, and the assembly configuration in the upper beam 1 will be described, but it should be noted that The same is true in any of the embodiments 1 to 4.

The top surface of the upper beam 1 has an opening having a length L1 in the front-rear direction, and has a housing space having a length of substantially L2 (> L1) in the front-rear direction. The rope supporting unit 5b composed of the inclined drum 51, the winding shaft 52, and the obstacle detecting and stopping device 53 is housed in the support casing 50, and is disposed on the upper beam 1 in such a manner that the sway in the front-rear direction and the up-and-down direction is restricted. This length is the storage space of L2. Therefore, when the rope supporting unit 5b housed in the support casing 50 is placed in the upper beam 1, the top surface of the upper beam 1 is enlarged, and the openings are provided at both ends in the left-right direction of the upper beam 1. Not shown) Insert and set.

Further, as shown in FIG. 15, the length d between the side surface of the drive transmission input side of the housing member 55a, 55b of the delay unit 5a and the side of the drive transmission output side of the shaft portion 561 is smaller than that of the upper beam 1 as seen from above. The opening length L1 on the top surface. Therefore, the delay unit 5a can be easily disposed at a desired position in the housing space of the upper beam 1. In other words, when the delay unit 5a is provided in the upper beam 1, it is not necessary to enlarge the top surface of the upper beam 1, or to be inserted from an opening (not shown) at both ends of the upper beam 1 in the left-right direction.

Further, as shown in FIG. 15, the shape of the delay unit 5a is such that the delay unit 5a is located in a circle S whose center of gravity Op is a center and whose diameter is D (≤ L2). Therefore, after the delay unit 5a is disposed in the upper beam 1, the delay unit 5a can be rotated, for example, by the center of gravity Op, so that the delay unit 5a and the connection object, that is, the rope supported in the support housing 50, can be supported. Units 5b are opposite each other.

More specifically, when the delay unit 5a is assembled in the upper beam 1, first, as shown in FIG. 16(a), the delay unit 5a is placed in the storage space of the upper beam 1 to be close to the connection object, that is, stored in the The position of the rope supporting unit 5b in the support housing 50 is at the position. Then, as shown in FIG. 16(b), the delay unit 5a is rotated in the accommodation space of the upper beam 1, so as to be opposed to the connection object, that is, the rope supporting unit 5b housed in the support casing 50. Set.

Further, as shown in the plan view of (a) of FIG. 17, a plurality of delay units 5a and a plurality of rope supporting units 5b are disposed in the upper beam 1 in accordance with the specifications of the horizontal blinds. Further, as shown in (a) of FIG. 17, the orientation of the plurality of rope supporting units 5b is disposed in accordance with the hanging position of the lifting cord 10, and the delay is assigned according to the orientation of each of the rope supporting units 5b to be connected. The orientation of unit 5a. Further, as shown in (a) of FIG. 17, the directional control rope supporting member 6 may be disposed at an appropriate position in accordance with the specifications of the horizontal louver.

Next, as shown in the plan view of FIG. 17(b), a plurality of delay units 5a disposed in the upper beam 1 are inserted into openings (not shown) at both ends of the upper beam 1 from the left and right sides of the upper beam 1. After the functional components such as the operation unit 2 are disposed in the plurality of rope supporting units 5b and the directional control rope supporting members 6, the both ends of the upper beam 1 in the left-right direction are closed by the side cover 1c.

At this time, the assembly steps of the prior art are explained using the reference symbols of the present invention as follows: when the drive shaft 11 is inserted into the plurality of rope supporting units 5b, it is necessary to fix the fixed position of the lifting cord 10 on all the winding shafts 52 ( The initial winding amount and the fixed position of each winding shaft 52 are simultaneously aligned while being inserted. On the other hand, the delay unit 5a according to the first to fourth embodiments of the present invention can be freely combined and separated from the plurality of rope supporting units 5b, and the drive shaft 11 can be easily inserted when the drive shaft 11 is inserted, so that the delay can be reduced. The cost (burden) of the assembly.

That is, in the assembly step according to the present invention, the fixed position of the lifting cord 10 on all the winding shafts 52 (the initial winding amount and the fixed position of each winding shaft 52) can be made after the insertion of the drive shaft 11 quasi.

More specifically, after simply inserting the drive shaft 11 as described above, as shown in the top view of (c) of FIG. 17, for the setting of the plurality of delay units 5a, in order to initialize the state of each delay unit 5a, The drive shaft 11 is simply rotated a few turns (about two turns) by the operating rope 3. That is, the projections and the projections inside the respective delay units 5a are initialized in order to initialize the state (for example, the projections 603 on the input shaft member 60 and the projections on the rotary intermediate plate 59 in the example shown in Fig. 12) The positions of the projections 564) on the 592a and 594 and the output shaft member 56 are identical, and the drive shaft 11 is simply rotated by a few turns (two or so) by the operation cord 3.

Next, as shown in the plan view of (d) in FIG. 17, after the fixing position (illustration S) of the lifting/lowering cord 10 on the winding shaft 52 that can be idly rotated with respect to the drive shaft 11 in each of the rope supporting units 5b is aligned, Each of the delay units 5a is connected to each of the connection objects opposed thereto, that is, the rope supporting unit 5b, by a sliding operation in the left-right direction. In the delay unit 5a of each of the above-described Embodiments 1 to 4, since the upper corner portion 550a which is recessed in a quadrangular shape is formed on the case members 55a, 55b having the lower corner portion 550b, and the upper corner portion 550a and the upper beam 1 are formed Since the upper end is engaged, it is possible to suppress the sway in the front-rear direction and the up-and-down direction when the delay unit 5a slides. Thereby, the state of each delay unit 5a can be easily initialized, and the positions of the winding shafts 52 in the respective rope supporting units 5b can be aligned, and the lifting operation of the blades 4 that are balanced in the left-right direction can be realized.

Further, since the claw portions 558 are formed in the case members 55a and 55b of the delay unit 5a, the claw portions 558 can be prevented from being delayed by the protrusions 50b on the support case 50 of the string supporting unit 5b. The unit 5a is shaken in the left and right direction. In particular, since the claw portion 558 of the delay unit 5a is formed at a position where it can be grasped from the top surface opening of the upper beam 1 to grip the projection portion 50b of the rope supporting unit 5b as the connection object (the length is in FIG. (b) at a position within the range of the length L1 shown, the delay unit 5a can be easily coupled to the rope supporting unit 5b as the connection target. In the prior art, it is necessary to assemble while confirming the connection state between the drive shaft 11 and the winding shaft 52. However, since the connection state cannot be observed, the cost (burden) at the time of assembly is large, and from this point of view, each embodiment The delay unit 5a of 1 to 4 can also reduce the assembly cost (burden).

Further, in the delay unit 5a of each of the first to fourth embodiments, as shown in FIG. 18(a), the claw portion 558 is engaged with the protruding portion 50b of the support case 50, thereby being gripped. The shaft portion 561 (the octagonal shaft in the illustrated example) of the output shaft member 56 of the delay unit 5a and the shaft hole 531a (the octagonal shaft hole in the illustrated example) of the cam shaft 531 of the obstacle detecting and stopping device 53 are arranged. Although the example of the connection has been described, the shaft portion 561 and the cam shaft 531 may be directly grasped (fitted) to realize the shaft connection.

For example, as shown in FIG. 18( b ), the shaft portion 561 and the cam shaft 531 may be directly gripped (fitted) to realize the shaft connection. Referring to (b) of FIG. 18, in the delay unit 5a, instead of providing the claw portion 558, the shaft portion 561 of the output shaft member 56 is formed into a cylindrical shape, and two inner circumferential surfaces 561a thereof are opposed to each other. A convex portion 561b is provided at the position. Further, at two positions where the inner peripheral surface 561a of the shaft portion 561 perpendicularly intersects the two convex portions 561b opposed to each other, two elastically deformable engagements are provided so as not to hinder the passage of the drive shaft 11 Slice 561d. A fitting protrusion 561c is provided on an outer surface of each of the engaging pieces 561d opposite to the axial center of the inner peripheral surface 561a. Further, instead of forming the joint portion of the cam shaft 531 of the obstacle detection stopping device 53 as the shaft hole 531a shown in FIG. 18(a), the outer peripheral surface shape of the cam shaft 531 is formed to have the portion 5310 and the portion 5319. The two-layered stepped shape is provided with a recess 531b at two positions opposite to each other at the portion 5319. Further, the surface of the joint portion of the cam shaft 531 is provided with a fitting wall 531c having a diameter smaller than the diameter of the inner peripheral wall of the shaft hole 5313 constituting the cam shaft 531, and the drive shaft 11 can pass through the fitting. Wall 531c.

Further, the two convex portions 561b of the shaft portion 561 opposed to each other can be engaged with the two concave portions 531b facing the portions 5319 of the cam shaft 531, and the shaft portion 561 is coupled in a state of being coupled by the engagement. The connection-side distal end portion is located at a position that is almost in contact with the portion 5310 of the cam shaft 531, and the fitting projection portion 561c of the elastically deformable engagement piece 561d of the shaft portion 561 is fitted to the fitting wall 531c of the cam shaft 531 and grasped. By this, the shaft portion 561 of the delay unit 5a is locked to the locking portion of the cam shaft 531. The support case 50 rotatably supports the cylindrical shaft portion 561 of the output shaft member 56 in a state of being coupled by the engagement. In addition, (b) of FIG. 18 shows only one example, and various modifications such as the shape of the convex portion 561b and the concave portion 531b may be interchanged.

(Horizontal louver having a rope supporting device that suspends the directional control rope having an annular upper end portion) Next, a horizontal louver including the rope supporting devices 5L, 5M, and 5R according to the present invention will be described with reference to FIG. 22 .

First, in the horizontal louver shown in Fig. 22, the rope supporting devices 5L, 5M, and 5R according to the present invention are disposed on the left end side, the center side, and the right end side in the upper beam 1, respectively.

Each of the rope supporting devices 5L, 5M, and 5R suspends and supports the plurality of layers of the blades 4 via a pair of string-like direction control ropes 9 suspended from the indoor side and the outdoor side, and the lower beam 8 is suspended and supported by the lower ends of the respective direction control ropes 9. The upper beam 1 is fixed to the mounting surface on the ceiling side via the bracket 7.

Further, the string-shaped lifting/lowering cord 10 is suspended from the respective rope supporting devices 5L, 5M, and 5R through the bottom surface of the upper beam 1 in the rear direction and substantially at the center portion, and the lower end of the lifting rope 10 passes through the front and rear directions of the respective blades 4. The insertion hole (not shown) in the center portion is fixed to the lower beam 8 afterwards. Further, the hanging position of the lifting cord 10 may be provided at the front and rear end portions of the respective blades 4.

That is, each of the rope supporting devices 5L, 5M, and 5R of the present example is configured such that the inclined drum 51 that suspends the pair of direction control ropes 9 that hangs from the indoor side and the outdoor side, and the winding rope 10 that can be wound or unwound The long cylindrical winding shafts 52 whose outer peripheral surfaces are inclined are arranged side by side on the four-bar-shaped drive shaft 11, and are supported by the support casing 50. Further, an obstacle detecting and stopping device 53 is provided on the front end side of the winding shaft 52.

In particular, in each of the rope supporting devices 5L, 5M, and 5R of the present embodiment, the upper end portions of the pair of directional control ropes 9 that are suspended from the indoor side and the outdoor side are formed in a ring shape and attached to the inclined drum 51. The direction control rope 9 is suspended, and the blade 4 supported by the horizontal rope of the direction control rope 9 is rotated by the rotation of the inclined drum 51. Further, on the topmost blade 4, a blade pressing plate 12 for holding the blade 4 supported by the horizontal rope of the direction control rope 9 is provided. The blade pressing plate 12 guides the pair of directional control ropes 9 suspended from the indoor side and the outdoor side to hang down, and is engaged and fixed to the blade 4 from below to support the horizontal rope supporting the directional control rope 9 of the topmost blade 4 together with the blade 4. Keep it. Further, a slit or an insertion hole (not shown) is provided in the vane pressure plate 12 to prevent the movement of the lift cord 10 from being hindered.

Therefore, the upper ends of the pair of directional control cords 9 which are respectively suspended from the indoor side and the outdoor side are connected so as to form an annular upper end portion, and the inclined drum 51 has a V-shaped groove in which the annular upper end portion is attached with a predetermined frictional force. This will be explained after the details.

Here, in each of the rope supporting devices 5L, 5M, and 5R shown in FIG. 22, the delay unit 5a shown in FIG. 2 and the like described above is not provided, and the inclined drum 51 and the winding shaft 52 are coupled to each other so as not to be relatively rotatable. Drive shaft 11.

However, each of the rope supporting devices 5L, 5M, and 5R may be configured similarly to the rope supporting device 5 shown in FIG. 2 described above, that is, the inclined drum 51 may be coupled to the drive shaft 11 so as not to be relatively rotatable. The winding shaft 52 is not coupled to the drive shaft 11 (not engaged), and is provided with a delay unit 5a that operates to rotate the winding shaft 52 in association with the rotation of the inclined drum 51 by a predetermined delay amount. .

Further, in this example, an example in which three rope supporting devices 5E, 5M, and 5R are provided in the horizontal louver is shown. However, two rope supporting devices may be provided or provided. More than four rope support devices. Further, the rope supporting device according to the present invention described later may be configured as a device that supports only the inclined drum 51a, such as the direction controlling rope supporting member 6, as shown in Fig. 1, wherein the inclined drum 51a has a mounting from the indoor side and the chamber, respectively. A pair of directional bearings on the outside side control the V-shaped grooves of the cord 9.

An operation unit 2 is provided on the right end side of the upper beam 1. In the case of the manual type shown, the operation unit 2 has a pulley (not shown) capable of attaching the operation cord 3 (or an annular bead chain) in the shape of a ring rope, and is permeable to the upper beam. The operation cord 3 is pulled out toward the outside and the drive shaft 11 is rotationally operated.

Alternatively, in the case where the operation unit 2 is of an electric type, an electric motor that can rotationally operate the drive shaft 11 in accordance with an external operation signal can be used. Therefore, the form of the operation unit 2 may be any form as long as it can transmit rotation to the drive shaft 11 in accordance with the operation of the operator.

Therefore, in the horizontal louver shown in Fig. 22, the drive shaft 11 is rotated by operating the operation cord 3, and the tilt drum 51 of each of the rope supporting devices 5L, 5M, 5R is rotated in accordance with the rotation of the drive shaft 11. Thereby, the tilting operation of adjusting the angle of the blade 4 can be performed. Further, when the drive shaft 11 is rotated beyond the number of turns required for the tilting operation, the lifting operation of raising or lowering the blade 4 can be performed while maintaining the state in which the blade 4 is rotated by the tilting operation.

Hereinafter, the structure and operation of the representative rope supporting device 5M among the rope supporting devices 5L, 5M, and 5R are mainly based on the prior art and the technology of the present invention from the viewpoint of the rope arrangement of the direction control rope 9. Examples 1 to 4) are explained in more detail.

(Based on the rope arrangement of the directional control rope according to the prior art) (a) in Fig. 23 shows a partial front view around the rope supporting device 5M which suspends the directional control cord 9 having an annular upper end portion according to the prior art, (b) A side view around the rope supporting device 5M that suspends the direction control cord 9 having one annular upper end portion (the description of the lifting cord 10 is omitted).

First, as shown in FIG. 23(a), in the rope supporting device 5M placed in the upper beam 1, the winding shaft 52 (illustrated in a non-sectional view) and the inclined drum 51 (in the form of a sectional view) The illustrations are provided on the drive shaft 11 so as not to be relatively rotatable, and are respectively supported by the support housing 50. The winding shaft 52 has a long cylindrical shape in which the outer peripheral surface is inclined, and the upper end of the lifting cord 10 is fixed to the winding shaft 52, so that the winding or unwinding of the lifting cord 10 can be performed, and the lower end of the lifting cord 10 is passed through, for example, An insertion hole (not shown) of a substantially central portion of each of the blades 4 in the front-rear direction is fixed to the lower beam 8 (see Fig. 22).

The plurality of layers of the blades 4 are supported between the pair of directional control ropes 9 hanging from the indoor side and the outdoor side through one or two horizontal ropes 9a provided at predetermined intervals. Further, the topmost blade 4 is provided with a blade presser 12 for holding the blade 4 supported by the horizontal rope 9a of the direction control rope 9.

Further, in the prior art, as shown in (b) of FIG. 23, the upper ends 91F and 91R of the pair of directional control ropes 9 which are suspended from the indoor side and the outdoor side respectively pass through the locking members (for example, the rivet metal members) 13 . They are joined to form an annular upper end. In the example shown in (b) of FIG. 23, the locking member 13 is disposed above the blade 4 without impeding the rotation of the blade 4.

As shown in (a) of FIG. 23, the inclined drum 51 has a V-shaped groove 51V whose width gradually narrows toward the center axis of the inclined drum 51, and the width of the groove bottom 51b of the V-shaped groove 51V is smaller than that of the direction control rope 9. The diameter of the section. Further, generally, the cross section of the direction control cord 9 is not completely circular, but has a substantially square cross-sectional shape having long sides and short sides, and the width of the groove bottom 51b is smaller than the width of the short side.

In other words, the inclined drum 51 passes through the V-shaped groove 51V to mount the annular upper end portion of the direction control rope 9 in a state where a predetermined frictional force is generated.

Thereby, in the rope supporting device 5M including the inclined drum 51, the inclined drum 51 rotates in accordance with the rotation of the drive shaft 11, and the plurality of layers of blades 4 supported by the horizontal rope 9a of the direction control rope 9 can be rotated. Here, the inclined drum 51 is configured such that the one annular upper end portion of the direction control rope 9 is attached in a state where a predetermined frictional force is generated by the V-shaped groove 51V.

In particular, compared with the structure in which the direction control rope 9 is suspended by the suspension member 511 as shown in FIG. 7, the inclined drum 51 that suspends the direction control rope 9 by the V-shaped groove 51V is configured to greatly reduce the transmission operation rope 3. It is advantageous to load the operation in which the drive shaft 11 is rotated.

That is, as shown in Fig. 7, in the configuration in which the directional control cord 9 is suspended by the suspension member 511, the suspension member 511 is constituted by a torsion coil spring, and both ends of the torsion coil spring are bent to form an annular directional control cord fixing portion 511a. And the locking end portion 511b. The upper ends of the pair of front and rear direction control ropes 9 are fixed to the direction control rope fixing portion 511a and are suspended and supported. Further, the suspension member 511 is tightly wound and fixed to the inclined drum 51, and the suspension member 511 and the inclined drum 51 integrally rotate before the locking end portion 511b abuts against the wall portion formed on the support casing 50. When the locking end portion 511b abuts against the wall portion formed on the support housing 50, the fastening force thereof becomes weak and idling with respect to the inclined drum 51. Thereby, the angle of each blade 4 can be adjusted in phase by the rotation of the inclined drum 51 and via the direction control rope 9. However, at this time, a load corresponding to the force for weakening the fastening force of the suspension member 511 is applied to the operation cord 3, and thus, from the viewpoint of reducing the operation force, the suspension direction is configured by the V-shaped groove 51V as shown in FIG. The inclined drum 51 of the control rope 9 is more advantageous.

However, as the form of the horizontal louver, since the length and width of the blade 4 are different, and the number of layers of the blade 4 is also different, the load applied to the directional control rope 9 is also different. Therefore, as one of the horizontal blinds, the frictional resistance applied to the direction control rope 9 through the V-shaped groove 51V may be insufficient, and although the operation force of the operation cord 3 is reduced, the direction control rope 9 moves in the V-shaped groove 51V. It will slip heavily, resulting in poor operability. In order to improve this, the shape of the V-shaped groove 51V may be changed depending on the form of the horizontal blind, but a technique capable of changing or adjusting the frictional resistance more easily is desired.

Further, in the technique of additionally providing a friction member with respect to the direction control rope 9, the friction member changes between the contact state and the non-contact state by the rotation of the inclined roller 51, and therefore, the friction member and the inclined roller 51 The contact may become insufficient due to the swing of the direction control cord 9, etc., and there is a possibility that the rotation of the blade 4 is not good.

Therefore, the rope supporting device 5M according to the present invention is configured to mount the directional control rope 9 in a state in which a predetermined frictional force is generated by the outer peripheral surface (the V-shaped groove 51V in this example) formed on the inclined drum 51. The annular upper end portion, the direction control rope 9 is rotated by the rotation of the inclined drum 51, and the blade 4 is rotated. Hereinafter, the rope supporting device 5M of the first to fourth embodiments will be described.

In addition, (a) of FIG. 24 is illustrated in a manner comparable to (b) of FIG. 23, and illustration of the winding shaft 52 and the lifting cord 10 is omitted. Further, it is also possible to form a device including only the inclined drum 51 without providing the winding shaft 52.

Further, the topmost blade 4 is provided with a blade presser 12 for holding the blade 4 supported by the horizontal rope 9a of the direction control rope 9.

Similarly to (a) of FIG. 23, the inclined drum 51 shown in (a) and (b) of FIG. 24 has a V-shaped groove 51V which gradually narrows in width toward the central axis of the inclined drum 51. The width of the groove bottom 51b of the V-shaped groove 51V is smaller than the sectional diameter of the direction control rope 9. Further, generally, the cross section of the direction control cord 9 is not completely circular, but has a substantially square cross-sectional shape having long sides and short sides, and the width of the groove bottom 51b is smaller than the width of the short side.

Further, as shown in (b) of FIG. 24, the upper end 91F of the rope 9 is suspended from the indoor side, and is attached to the V-shaped groove 51V of the inclined drum 51 from the indoor side, and then passes through the locking member (for example, The metal member 13a is swaged and locked to the direction control cord 9 that is suspended from the outdoor side. Further, the upper end 91R of the direction control rope 9 that is suspended from the outdoor side is attached to the V-shaped groove 51V of the inclined drum 51 from the outdoor side, and then is locked by the locking member (for example, the crimped metal member) 13b. The direction in which the indoor side hangs is on the control rope 9. In the examples shown in (a) and (b) of FIG. 24, the locking members 13a and 13b are disposed above the blade 4 and do not interfere with the rotation of the blade 4, but may be formed as: The members 13a, 13b are located below the blade 4 and do not interfere with the rotation of the blade 4.

Thereby, the direction control rope 9 forming the two annular upper end portions is hung in the V-shaped groove 51V, and the direction control rope 9 is rotated in accordance with the rotation of the inclined drum 51, so that the friction at the time of rotation of the blade 4 can be increased. resistance.

Further, when the two annular upper end portions are formed, the rope arrangement of the direction control rope 9 on the indoor side and the rope arrangement of the direction control rope 9 on the outdoor side can be placed on the upper side (or the lower side), and the card can be used. The fixed members 13a and 13b are locked in a state where no distortion occurs in the range of rotation of the blade 4. Generally, the cross-sectional shape of the direction control cord 9 has a substantially square shape having a long side and a short side. Therefore, in order to prevent the occurrence of distortion when the two annular upper end portions are formed, the faces of the direction control cords 9 are made to correspond to each other and the card is used. The fixed members 13a and 13b can be locked.

(Line support device of the second embodiment) Fig. 25(a) is a partial side view showing the vicinity of the rope supporting device 5M according to the second embodiment of the present invention, and Fig. 25(b) is a schematic view showing the rope arrangement. In addition, (a) of FIG. 25 is illustrated in a manner comparable to (b) of FIG. 23, and illustration of the winding shaft 52 and the lifting cord 10 is omitted. Further, it is also possible to form a device including only the inclined drum 51 without providing the winding shaft 52.

As shown in (a) and (b) of FIG. 25, in the rope supporting device 5M placed in the upper beam 1, the inclined drum 51 is provided so as not to be rotatable relative to the drive shaft 11, and the inclined drum 51 is provided. Supported by the support housing 50.

The plurality of layers of the blades 4 are supported between the pair of directional control ropes 9 hanging from the indoor side and the outdoor side through one or two horizontal ropes 9a provided at predetermined intervals. Further, the topmost blade 4 is provided with a blade presser 12 for holding the blade 4 supported by the horizontal rope 9a of the direction control rope 9.

Similarly to (a) of Fig. 23, the inclined drum 51 shown in (a) and (b) of Fig. 25 has a V-shaped groove 51V which gradually narrows in width toward the central axis of the inclined drum 51. The width of the groove bottom 51b of the V-shaped groove 51V is smaller than the sectional diameter of the direction control rope 9. Further, generally, the cross section of the direction control cord 9 is not completely circular, but has a substantially square cross-sectional shape having long sides and short sides, and the width of the groove bottom 51b is smaller than the width of the short side.

Further, as shown in (b) of FIG. 25, the upper end 91F of the cord 9 is suspended from the indoor side, and is attached to the V-shaped groove 51V of the inclined drum 51 from the indoor side, and then passed through the locking member (for example, The metal member 13 is riveted and locked to the direction control cord 9 that is suspended from the outdoor side. Further, the upper end 91R of the direction control rope 9 suspended from the outdoor side is placed in the V-shaped groove 51V of the inclined drum 51 from the outdoor side, and then placed along the topmost horizontal rope 9a and transmitted through the locking member ( For example, the riveted metal member 13 is locked with the upper end 91F on the direction control cord 9 that hangs from the outdoor side. In the examples shown in (a) and (b) of FIG. 25, the locking member 13 is disposed above the blade 4 and does not interfere with the rotation of the blade 4, but may be formed such that the locking member 13 is located.
