Description

  The present invention relates to a horizontal blind.

  In general, a horizontal blind, which is a type of solar shading device, has a large number of slats suspended from a head box via a ladder cord. Such a horizontal blind has a mechanism for adjusting the tilt angle of the slat. When the slats are at an angle close to vertical, the slats that are adjacent to each other at the top and bottom are partially overlapped, so that it is required to provide total shielding that does not allow light to pass between the adjacent slats. For example, in the horizontal blind shown in Patent Document 1, the width of the blade plate (slat) is made longer than the distance between the adjacent horizontal rails (lateral pitch lines) of the guide cord (ladder cord warp) and the width of the blade plate. Also disclosed is a structure in which the length of the cross rail is increased.

  By the way, in the horizontal blind described in Patent Document 1, the shielding property is enhanced by increasing the width of the blades more than the distance between the horizontal rails and increasing the amount of intersection between adjacent blades. However, since the length of the horizontal rail is made longer than the width of the slats, when the slats are pulled to the head box side to be in a contracted state, the slats tend to be laterally shifted (longitudinal shift). . Even if the slats are suspended from this state, the lateral displacement of the slats is not eliminated. As a result, there is a problem in that the position of the end portion in the longitudinal direction of the blade plate varies from blade to blade and the appearance is impaired.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a horizontal blind having a good appearance while suppressing the lateral displacement of the slats while maintaining the shielding property. .

  In order to solve the above problems, the horizontal blind according to the present invention is arranged at a predetermined pitch between the head box and the bottom rail, and a notch is formed at one end in the width direction orthogonal to the longitudinal direction.

  According to another aspect of the present invention, the slat lateral slip prevention member is a foldable cord member, and one end portion of the cord member is first between the head box and the uppermost slat near the head box. It is preferable that the other end portion of the cord member that is fixed to the warp yarns and stretched along the first warp yarn is fixed to the bottom rail.

  In another aspect of the invention, the lateral pitch line is composed of an upper weft and a lower weft that sandwich the slat, and the head box side uppermost slat and the bottom rail side lowermost slat, It is preferable that the cord member is disposed between the upper weft and the lower weft and extends along the first warp while alternately changing the front and back positions with respect to the cord member.

  In another aspect of the invention, the slat lateral deviation prevention member is preferably a ring member loosely fitted to the first warp or a ring member loosely fitted to the weft.

In the following description, the X-direction is the longitudinal direction of the horizontal blind 10, and the X1 side is the right end side of FIG. 1, and the X2 side is the left end of FIG. Let it be the side. Further, the Z direction is the hanging direction (vertical direction) of the horizontal blind 10, the Z1 side is the upper side of FIG. 1, and Z2 is the lower side of FIG. The Y direction is a direction orthogonal to the X direction and the Z direction, the Y1 side is the indoor side where the operation pole 70 is located, and Y2 is the opposite side.

(Configuration of horizontal blind)
FIG. 1 is a front view showing the configuration of the horizontal blind 10, and FIG. 2 is a side view showing a part of the configuration of the horizontal blind. 2A shows a lateral slip prevention mechanism of the horizontal blind 10, and FIG. 2B shows an enlarged detail of the support structure of the slat 30. As shown in FIG. As shown in FIGS. 1 and 2, the horizontal blind 10 is arranged between the head box 20 and the bottom rail 60 at a position spaced between both ends in the longitudinal direction (X direction) of the slat 30. A large number of slats 30 are suspended at predetermined pitches via the ladder code 41. A holder 61 is attached to the lower end side (Z2 side) of the ladder cord 41, and the ladder cord 41 is attached to the bottom rail 60 via the holder 61.

As shown in FIG. 2, the ladder cord 41 includes a first warp thread 41 a, a second warp thread 41 b, and a first warp thread 41 b that are disposed so as to sandwich both sides in the width direction (Y direction) orthogonal to the longitudinal direction of the slat 30. Of the vertical warp yarn 41a and the second warp yarn 41b. The lateral pitch line includes an upper weft thread 43 on the front surface side (Z1 side) of the slat 30 and a lower weft thread 44 on the back surface side (Z2 side), and supports the slat 30 so as to sandwich the slat 30 therebetween. Yes. The upper weft thread 43 and the lower weft thread 44 intersect between the first warp thread 41a and the second warp thread 41b, and the upper weft thread 43 and the lower weft thread 44 are the first warp thread at the connecting portion with the second warp thread 41b. The connecting portion is turned upside down with respect to the connecting portion with 41a. The horizontal pitch line has a function of hanging a large number of slats 30 at a predetermined pitch.
The upper weft 43 and the lower weft 44 are thinner than the first warp 41a and the second warp 41b.

  The slat 30 is inserted and supported between the first warp thread 41a and a weft crossing portion 45 where the upper weft thread 43 and the lower weft thread 44 intersect. As shown in FIG. 2, the length of the weft pitch line (upper weft thread 43 and lower weft thread 44) is set to be longer than the width dimension (Y direction dimension) of the slat 30 with the slat 30 fully opened. . That is, when the slat 30 is fully opened, the distance between the first warp 41 a and the second warp 41 b is sufficiently longer than the width of the slat 30.

  As shown in FIG. 2B, a notch portion 35 is formed at the end of the slat 30 in the Y1 direction, and the lower weft 44 enters the notch portion 35 so that the longitudinal direction (X (Direction) is restricted to the formation range of the notch 35. The shape of the notch 35 is, for example, a rectangle. The lower weft 44 is bent in the Z2 direction by its own weight, and the slat 30 is supported substantially horizontally.

Between the first warp 41a and the end of the slat 30 opposite to the end where the notch 35 is formed, a lateral slip prevention cord 52 as a cord member is disposed as a slat lateral slip prevention member. Has been. The lateral slip prevention cord 52 is disposed between the upper weft thread 43 and the lower weft thread 44 as shown in FIG. Moreover, the lateral slip prevention cord 52 is stretched along the first warp yarn 41a while alternately changing the longitudinal position (front and back position) between the upper weft yarn 43 and the lower weft yarn 44 with respect to the lateral slip prevention cord 52. Yes. One end of the lateral slip prevention cord 52 is fixed to the first warp 41a by a fastener 56 such as a fixing ring between the head box 20 and the uppermost slat 30 close to the head box 20, and the other end. The part is fixed to the bottom rail 60.
2 and the subsequent drawings showing the embodiments and examples, the distance between the first warp 41a and the lateral deviation prevention cord 52 is exaggerated for easy identification.

The fixing position of one end (upper end) of the lateral slip prevention cord 52 described above is such that when the slat 30 is pulled up, the fastener 56 does not enter the head box 20 and the tilt angle (Y of the slat 30) This is the position that does not hinder the adjustment of the angle of inclination) and the pulling-up and hanging-down operations.
The lateral displacement prevention cord 52 can be fixed to the holder 61 together with the ladder cord 41. Further, the lateral slip prevention cord 52 is movable between the first warp 41 a and the slat 30.

  The raising / lowering cord 51 is arrange | positioned between the 2nd warp yarn 41b and the weft crossing part 45, as shown to Fig.2 (a), (b). Moreover, the raising / lowering cord 51 is extended | stretched along the 2nd warp yarn 41b, arrange | positioning between the upper weft 43 and the lower weft 44. As shown in FIG. 1, one end of the lifting / lowering cord 51 passes through the stopper device 21 in the head box 20, is further inserted into the operation pole 70, and is attached to the equalizer 71 (so-called one-pole type). . With such a structure, the lifting / lowering cord 51 is interlocked with the vertical movement of the equalizer 71, so that a stowed state in which a large number of slats 30 are stacked and a deployed state in which the slats 30 are arranged at a predetermined pitch can be easily realized. However, instead of the one-pole type, other types such as a separate pole type, a chain type, etc., in which the lifting / lowering cord 51 and the operation pole 70 are separate may be used.

  The stopper device 21 is in a restricted state in which the elevating cord 51 is prevented from moving in a direction in which the slat 30 is lowered, and in a released state in which the elevating cord 51 is allowed to move in a direction in which the slat 30 is lowered. It is possible to switch.

  The upper end side (Z1 side) of the ladder cord 41 is attached to a support drum 22 provided in the head box 20. The support drum 22 is rotatably attached to the housing 24 of the head box 20 via the support member 23. A fitting hole (not shown) is provided on the radial center side of the support drum 22, and a rotation shaft 25 is inserted into the fitting hole so that the support drum 22 and the rotation shaft 25 rotate integrally. Is provided.

  A gear box 26 is provided on one end side (X1 side in FIG. 1) of the rotating shaft 25. The gear box 26 constitutes a universal joint provided with a gear (not shown) such as a worm wheel, and the operation pole 70 is connected. When the operation pole 70 is rotated to one side, the rotary shaft 25 is rotated to one side. The When the operation pole 70 is rotated in the reverse direction, the rotary shaft 25 is rotated in the reverse direction. As a result, the first warp thread 41a or the second warp thread 41b of the ladder cord 41 is pulled up, and the tilt angle of the slat 30 can be switched. The manual configuration of the present embodiment is an example, and may be a manual type, a cord type, or an electric blind.

Next, the action of the lateral slip prevention cord 52 related to pulling up and drooping of the slat 30 according to the present embodiment will be described with reference to FIG.
FIG. 3 is a side view showing the action of the lateral deviation prevention cord 52 related to pulling up and drooping of the horizontal blind 10. Note that FIG. 3 shows the angle of the standing posture of the slat 30 more gently than in actuality in order to facilitate the explanation of the relationship between the upper weft 43, the lower weft 44 and the slat 30. First, the case where the slat 30 is pulled up will be described with reference to FIG. FIG. 3A shows a state before the slat 30 is folded. In the state in which the slat 30 shown in FIG. 2B is fully open (the slat 30 is horizontal), the lower weft 44 enters the notch 35 of the slat 30, so that the lateral displacement of the slat 30 is notched 35. Is approximately within the range of the width.

  In the present embodiment, the slat 30 is pulled up in the reverse fully closed state, and as shown in FIG. 3A, the first warp 41a and the second warp 41b are relatively The positional relationship is shifted in the vertical direction (the direction is indicated by an arrow), and the distance between the first warp 41a and the second warp 41b is narrower than in the fully open state of the slats. As shown in the figure, in the slat 30, one end of the slat 30 is supported at an intersection (including the vicinity of the intersection) of the lateral slip prevention cord 52 and the lower weft 44. However, as the slats 30 are in the standing posture, the amount of entry into the lower weft 44 and the notch 35 becomes shallower, and therefore some of the large number of slats 30 may have the lower weft 44 and the notch 35. The slats 30 may be laterally displaced (displacement in the X1 or X2 direction) when they are disengaged and folded. In addition, the reverse fully closed of the slat 30 means the state where the notch part 35 is located on the upper side here.

  In the middle of pulling up the slat 30, the first warp thread 41a, the second warp thread 41b, and the lateral slip prevention cord 52 are alternately folded in the X1 direction and the X2 direction. Therefore, the first warp thread 41a, the second warp thread 41b, and the lateral slip prevention cord 52 are required to have the same foldability, and are preferably flat cords in the folding direction. In other words, it is desirable that the lateral slip prevention cord 52 is a flat plate member that is spun in which the thickness in the X direction is thinner than the width in the Y direction.

  Next, a case where the slat 30 is suspended from the folded state will be described with reference to FIG. The horizontal blind 10 of the present embodiment is pulled up in the fully closed state (reverse fully closed) shown in FIG. 3A, and the slats 30 are directed in the opposite direction (this state is assumed to be fully fully closed). Thereafter, the entire slat 30 is suspended. As shown in FIG. 3B, the posture of the slat 30 in the fully closed state is a standing posture in which the notch portion 35 is directed downward (Z2 direction). As shown in FIG. 3B, the first warp 41a and the second warp 41b are in a positional relationship in the opposite vertical direction (indicated by an arrow) with respect to normal full close.

  In the transition process from reverse fully closed to normal fully closed, once the distance between the first warp 41a and the second warp 41b is increased to the same extent as the slat fully open (see FIG. 2), the slat 30 is rotated, The fully closed state shown in FIG. In the normal fully closed state, the slats 30 have a reverse vertical positional relationship with respect to the reverse fully closed state.

  As described above, in the reverse fully closed state shown in FIG. 3A, in some of the many slats 30, there are some in which the lower weft 44 is not inserted into the notch 35. In the present embodiment, when the lateral slip prevention cord 52 extends from the folded state in the process of transition from reverse fully closed to normal fully closed, and in the process of hanging, it is between the upper weft thread 43 and the lower weft thread 44. The lateral slip prevention code 52 is located. The gap between the slat 30 and the first warp thread 41a is narrow in the immediate vicinity of the connecting portion between the upper weft thread 43 and the lower weft thread 44 and the first warp thread 41a. Therefore, if the lateral slip prevention cord 52 is installed, the gap between the first warp thread 41 a and the slat 30 is widened by the width of the lateral slip prevention cord 52. That is, the slat 30 is moved toward the second warp thread 41b. This makes it easier for the lower weft thread 44 to enter the notch 35 of the slat 30.

In the horizontal blind 10 described above, the result of actual measurement comparison of the amount of slat lateral displacement generated depending on the presence or absence of the lateral displacement prevention code 52 will be described.
FIG. 4 is a table comparing the amount of lateral displacement of the slat 30 (the amount of displacement of the end portion of the slat 30 in the X1 direction) with and without the lateral displacement prevention code 52, and when the total number of slats 30 is 83, The lateral deviation amount represents the result of measuring the number of occurrences in units of 1 mm from 0 mm to 6 mm. In addition, this measurement result compares the case where there is no lateral deviation prevention code 52 and the case where the lateral deviation prevention code 52 is provided in the same horizontal type bride.

  As shown in FIG. 4, the amount of lateral deviation tends to be smaller when the lateral deviation prevention code 52 is provided than when the lateral deviation prevention code 52 is absent. Here, comparing the number of occurrences between 3 mm and 6 mm, where the lateral displacement amount is relatively large, the lateral displacement occurrence number is 39 when the lateral displacement prevention code 52 is not provided, and the lateral displacement prevention code 52 is provided. In this case, the number of lateral deviations is 24. Further, when the lateral deviation amount is 0 mm, 1 mm, and 2 mm, the number of occurrences 44 when the lateral deviation prevention code 52 is not provided and the number of occurrences when the lateral deviation prevention code 52 is provided is 79. If the allowable value of the lateral deviation amount is set to 2 mm, a clear difference is seen in the number of lateral deviation occurrences, and the effect of providing the lateral deviation prevention code 52 can be confirmed.

  It should be noted that the slats 30 adjacent to the upper and lower stages in the Z direction maintain a good shielding property because a sufficient range can be secured to intersect each other in the reverse fully closed state and the normal fully closed state.

  In the present embodiment, the lateral shift prevention member 52 is disposed between the first warp thread 41 a and the end portion on the opposite side to the formation side end portion of the notch portion 35 of the slat 30. For example, when there is no lateral slip prevention cord 52, the gap between the slat 30 and the first warp 41a becomes narrow immediately near the connecting portion between the upper weft 43 and the lower weft 44 and the first warp 41a. The gap between the first warp thread 41a and the slat 30 can be widened by the width of the lateral slip prevention cord 52. Accordingly, the slat 30 is brought closer to the second warp thread 41 b by the width of the lateral slip prevention cord 52. As a result, the lower weft 44 can easily enter the notch 35 of the slat 30. When the lower weft 44 enters the notch 35 of the slat 30, the lateral displacement of the slat 30 that occurs when the slat 30 is pulled up can be corrected, and the horizontal blind 10 having a good appearance can be provided.

  In the present embodiment, the lateral slip prevention cord 52 is a foldable cord member that extends along the first warp 41a, and the uppermost end of the lateral slip prevention cord 52 is connected to the first warp 41a. It is fixed. According to such a configuration, when the slat 30 is pulled up or suspended or when the tilt angle is changed, the lateral slip prevention cord 52 can easily follow the folding and stretching of the first warp thread 41a. Accordingly, the lower weft thread 44 can easily enter the notch 35 of the slat 30. If the lower weft 44 easily enters the notch 35 of the slat 30, it is possible to correct the lateral displacement of the slat 30 that occurs when the slat 30 is pulled up.

  Furthermore, in this embodiment, the lateral slip prevention cord 52 is between the upper weft 43 and the lower weft 44 between the uppermost slat 30 close to the head box 20 and the lowermost slat 30 on the bottom rail 60 side. The first longitudinal yarn 41a is stretched while alternately changing the longitudinal position (front and back position) with respect to the lateral slip prevention cord 52. According to such a structure, the lateral slip prevention cord 52 does not deviate from the connecting position of the upper weft 43 and the lower weft 44 with the first warp 41a. That is, the contact position with the lateral displacement prevention cord 52 is not easily displaced for each slat 30. Therefore, each of the large number of slats 30 can exhibit the lateral deviation prevention function by the lateral deviation prevention code 52 described above.

  In the first embodiment, the lateral displacement prevention cord 52 is used as the slat lateral displacement prevention member, but is not limited to the lateral displacement prevention cord 52, and the object of the present invention can be achieved.

In the case of a simple ring shape, the upper weft thread 43 or the lower weft thread 44 can be assembled in an intermediate process in which the first warp thread 41a and the second warp thread 41b are knitted. Further, in the case of a ring wound in a spiral shape, it is possible to assemble the ring member 53 at a predetermined position of the first warp thread 41a while turning the ring member 53 along the spiral after the ladder cord 41 is formed.

  According to the three examples in the second embodiment described above, the ring member 53 has substantially the same function although the shape is different from that of the lateral slip prevention cord 52, so that the lateral displacement of the slat 30 is suppressed. A horizontal blind with excellent appearance can be realized.

  Although not shown, the structure having the same function as that of the ring member 53 is a projection corresponding to the ring member 53 illustrated in FIG. 5 between the upper weft 43 and the lower weft 44 of the first warp 41a.
