The present invention relates to a horizontal blind having a plurality of slats, and more particularly to a horizontal blind that moves up and down a plurality of slats suspended and supported by a ladder cord using a plurality of lifting cords.

The horizontal blind is provided with a plurality of slats supported by the ladder cord and a plurality of lifting cords for lifting and lowering the plurality of slats. The plurality of lifting / lowering cords are disposed, for example, at a central portion in the longitudinal direction of the slat and at both ends in the longitudinal direction of the slat, and are inserted through through holes formed in the central portion in the front-rear direction of each of the plurality of slats. Yes. Then, the plurality of slats are moved up and down by the operation of the plurality of lifting cords, and the plurality of slats are tilted all at once by the operation of the ladder cord (see Patent Document 1).

In other words, the horizontal blind can move up and down a plurality of slats supported by a ladder cord suspended from a head box using a plurality of lifting cords, and further, by operating the ladder cord and tilting the slats. The amount of solar radiation taken into the room can be adjusted.

Also, for example, a bottom rail is disposed at the lower end of the ladder cord, and the bottom rail is moved up and down by pulling the lifting cord attached to the bottom rail into the head box and pulling it out from the head box. Slats can be raised and lowered.

As this horizontal blind, an insertion hole through which the lifting / lowering cord is inserted is provided at a substantially central portion in the front / rear direction of the slat so that the slat can be moved up and down, and the operation unit is configured to be movable in the longitudinal direction on the front surface of the head box.

However, in the horizontal blind in Patent Document 1, since a through hole is formed in the center in the front-rear direction of each of the plurality of slats, when the slat is in a fully closed state, light is transmitted from the through hole formed in the slat. Leaks. The central portion in the longitudinal direction of the slat is a region that usually requires higher light shielding than the end portion in the longitudinal direction of the slat. In particular, it is required to suppress leakage.

In addition, since the horizontal blind in Patent Document 2 has a through-hole through which the lifting / lowering cord is inserted at a substantially central portion in the front-rear direction of the slat, light leaks from the through-hole even when the slat is tilted to be in a shielding state. Can occur.

In addition, by engaging the ladder cord with the notch of each slat, the lateral displacement of the slat can be suppressed, but such a notch can also cause light leakage.

On the other hand, when using a slat made of a hard material such as wood, there is a demand to install a plate-like member having the same quality as the slat on the front surface of the head box in order to make use of the design of the slat.

[First Embodiment]
Hereinafter, the horizontal blind according to the first embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the horizontal blind 10 includes a head box 11 that is attached to an attachment portion such as a ceiling, a window frame, and a curtain box, and a plurality of slats 12 that shield solar radiation. The horizontal blind 10 includes a ladder cord 13 that supports the slat 12 so that the tilt can be adjusted, a bottom rail 14 that is positioned below the lowermost slat 12, and a lifting tape that has one end fixed to the bottom rail 14. 15.

The slat 12 is formed of a synthetic resin plate, a metal plate such as stainless steel, and the like, is formed in an elongated rectangular thin plate shape, and the upper surface portion has an arcuate surface. The slat 12 may be formed of a wooden board. The plurality of slats 12 are arranged along the height direction and supported by a ladder cord 13 suspended from the head box 11 so as to be adjustable in tilt. A bottom rail 14 having a length substantially the same as that of the slat 12 is disposed below the lowermost slat 12. The bottom rail 14 functions as a weight member when maintaining the state where the plurality of slats 12 are lowered. The bottom rail 14 has substantially the same length and width as the slat 12, and when the bottom rail 14 is pulled up, a plurality of slats 12 are stacked on the bottom rail 14. The leading end of the ladder cord 13 is fixed to the bottom rail 14. A lifting tape 15 pulled out from the head box 11 is fixed to the bottom rail 14.

Most of the slats 12 in the plurality of slats 12 are an example of a slat group composed of a plurality of slats 12 arranged in the ascending / descending direction. First through holes 22 are formed at both longitudinal ends of the slats 12 constituting the slat group, and each of the first through holes 22 formed in the plurality of slats 12 is an example of a first elevating member. A certain lifting tape 15 is inserted. In each of the plurality of slats 12 constituting the slat group, the lifting tape 15 which is an example of the second elevating member is not inserted into the central portion in the longitudinal direction of the slat 12, and is necessary for the insertion of the lifting tape 15. The through hole is not formed. Among these regions occupied by the slat group, a high light-shielding property is ensured in the central portion in the longitudinal direction of the slat 12 because the above-described through hole is not formed.

Inside the head box 11, a plurality of drums 17 for winding the lifting tape 15 and a lifting mechanism such as a shaft body 18 for rotating the plurality of drums 17 in synchronization are arranged. The elevating mechanism here is, for example, electric, and uses the motor 20 disposed inside the head box 11 as a drive source to drive the motor 20 and elevate the slats 12 according to the user's operation. In the case of a manual lifting / lowering mechanism, an operation code is pulled out from the head box 11, and by operating the operation code, the shaft 18 is rotated via a transmission mechanism such as a pulley on which the operation code is multiplied. .

When the lifting tape 15 is wound up, the bottom rail 14 rises, and as the bottom rail 14 rises, the plurality of slats 12 are stacked on the bottom rail 14 in order from the position close to the bottom rail 14. When the lifting tape 15 is pulled out, the bottom rail 14 is lowered, and as the bottom rail 14 is lowered, each of the plurality of slats 12 is lowered until it is supported by the ladder cord 13.

As shown in each of FIGS. 1 to 3, two ladder cords 13 are arranged in the vicinity of both ends in the longitudinal direction of the slat 12, and further, one ladder cord 13 is arranged in the longitudinal direction of the slat 12. It is arranged near the central part. Further, the three lifting tapes 15 are arranged in the vicinity of the three ladder cords 13. Two lifting tapes 15 located at both ends in the longitudinal direction of the slat 12 are arranged inside the room, and one lifting tape 15 located in the middle part of the slat 12 in the longitudinal direction is arranged outside the room. Yes. Hereinafter, the lifting tape inside the room is referred to as a first lifting tape 15a, and the lifting tape outside the room is referred to as a second lifting tape 15b.

As shown in FIG. 4, the front end portion of each of the two first lifting tapes 15 a has a tape holder 16 together with the warp yarns 13 a of the two ladder cords 13 with respect to the long side end portion inside the room of the bottom rail 14. It is fixed by. The tip of one second lifting tape 15b is fixed to the central portion of the bottom rail 14 in the long side direction outside the room by the tape holder 16 together with the warp 13a of the ladder cord 13.

As shown in FIG. 4, the ladder cord 13 includes a pair of warp yarns 13a extending in the height direction of the horizontal blind 10, and a weft yarn 13b provided between the warp yarns 13a. The weft 13b supports each slat 12 from the lower side. The weft yarn 13b may be formed of an upper weft yarn and a lower weft yarn in an annular shape, and the slat 12 may be supported by passing the slat 12 between the upper weft yarn and the lower weft yarn. The length of the protrusion from the ladder cord 13 located on both ends of the slat 12 to the end is such that the slat does not bend due to its own weight, for example, about 150 mm to 200 mm.

The warp 13a of the ladder cord 13 includes a pico 13c through which the second lifting tape 15b is inserted. The pico 13c is an annular body formed by drawing a yarn from the warp 13a when the ladder cord 13 is a knitted string. The pico 13c is provided on the warp yarn 13a located outside the room, and the second lifting tape 15b extending outside the room is inserted through the pico 13c.

The looseness of the second lifting tape 15b is suppressed by passing the second lifting tape 15b through the pico 13c, and the second lifting tape 15b is supported by the pico 13c along the warp 13a of the ladder cord 13. The second lifting tape 15b does not need to be inserted through all the picos 13c, and the warp 13a may include picos 13c through which the second lifting tape 15b is not inserted. In addition, although the pico 13c was formed with the thread | yarn at the position of the knot of the warp 13a and the weft 13b and demonstrated as an annular part, you may comprise the annular body integrally formed in the warp 13a.

The base end portion of the warp 13 a in the ladder cord 13 is fixed inside the head box 11, and the tip end of the warp 13 a in the ladder cord 13 is fixed to the bottom rail 14 by the tape holder 16. Further, between the bottom rail 14 and the tape holder 16, the leading end of the lifting tape 15 is also sandwiched and fixed together with the leading end of the warp 13 a of the ladder cord 13. Further, a tape guide member 19 that guides the drawing position of the two first lifting tapes 15 a extending on both sides in the longitudinal direction inside the room is attached to the upper surface portion of the bottom rail 14 that faces the lowermost slat 12. It is done.

The two first lifting tapes 15 a on both ends in the longitudinal direction derived from the tape guide member 19 are derived from the first long side 21 a side of the bottom rail 14, and at the center portion derived from the tape holder 16. One second lifting tape 15b is led out from the second long side portion 21b side of the bottom rail 14. As a result, the bottom rail 14 is supported by the first lifting tape 15a and the second lifting tape 15b at three locations from both sides, and may be inclined in the front side that is the inside of the room or the rear side that is the outside of the room, that is, the front-rear direction. It is raised and lowered in a stable state.

As shown in each of FIGS. 5A, 5B, and 5C, all the slats 12 included in the horizontal blind have an elongated rectangular thin plate shape extending along the longitudinal direction. On the other hand, all the slats 12 included in the horizontal blind include three types of slats 12 having different through holes and different positions of the through holes.

As shown in FIG. 5A, the uppermost slat 12a guides a second lifting tape 15b, which is an example of a second elevating member, at the center of the second long side portion 21b located outside the room. Two through holes 23 are formed. A second lifting tape 15b extending outside the room is inserted through the second through hole 23. The second through hole 23 is a rectangular through hole that is slightly larger than the cross-sectional shape of the second lifting tape 15b, and the second lifting tape 15b is substantially parallel to the main surface portion of the slat 12a, and the winding surface of the drum 17 Guide it so that it can be wound up in accordance with. No through hole is formed in the first long side portion 21a inside the room of the uppermost slat 12a. The second through hole 23 can be easily formed by punching the slat 12a.

As shown in FIG. 5B, the second slat 12b from the top has no through hole formed in either the first long side 21a inside the room or the second long side 21b outside the room. .

As shown in FIG. 5 (c), the third and subsequent slats 12c from the top have first through holes 22 formed at both ends of the first long side portion 21a located inside the room. Most of the slats 12c after the third stage excluding the uppermost slat 12a and the second slat 12b closest to the head box 11 are slats 12 constituting the slat group described above.

In the two first through holes 22, two first lifting tapes 15a extending inside the room, which is an example of a first lifting member, are inserted. The first through-hole 22 is a rectangular through-hole slightly larger than the cross-sectional shape of the first lifting tape 15a, and the first lifting tape 15a is substantially parallel to the main surface portion of the slat 12c, and the winding surface of the drum 17 Guide it so that it can be wound up in accordance with. The slats 12c in the third and subsequent stages from the top have no through holes formed between the first through holes 22 on both ends. The first through hole 22 can be easily formed by punching the slat 12c.

Here, in a state where the head box 11 is ceiling-mounted in the window frame, both ends in the longitudinal direction of the slat 12 are in the vicinity of the vertical frame in the window frame, in other words, at positions where light shielding properties are secured by walls or the like. Be placed. When the head box 11 is faced to cover the window frame, or when the head box 11 is attached to the curtain box or the curtain rail, both end portions in the longitudinal direction of the slat 12 are also window frames. It is arranged in the vicinity of the vertical frame and outside thereof. Therefore, even when light leaks from the first through hole 22, such light is not conspicuous for the user. On the other hand, the second through-hole 23 formed in the central portion of the slat 12 in the longitudinal direction between the first through-holes 22 has a large amount of light leaking from now on, and such light is conspicuous for the user. It becomes.

In this regard, in the horizontal blind described above, the first through hole 22 is formed only at both longitudinal ends of the slat 12 in the third and subsequent slats 12 occupying most of all the slats 12. No other through hole is formed between the first through holes 22. Therefore, the light-shielding property is enhanced for the entire slat group, and hence the area occupied by all the slats 12.

In addition, the first through hole 22 is biased to the first long side portion 21a located inside the room of the slat 12c. In such a position of the first through hole 22, when all the slats 12 are tilted in one direction and are in a fully closed state where the solar radiation is blocked, the long side portions overlap each other, thereby It becomes easy to suppress light leakage.

However, as shown in FIG. 5 (a), the uppermost slat 12a closest to the head box 11 is provided with a second through hole 23 in the central portion in the longitudinal direction so as to be biased toward the second long side portion 21b. ing. The uppermost slat 12a is close to the head box 11 and is close to the window frame and is located on the upper side of the window frame even when it is mounted on the front or ceiling. Therefore, even when light leaks from the second through hole 23, the amount of light entering the shadow of the head box 11 or the like is small, and the overall light shielding performance is not significantly deteriorated.

As shown in FIG. 5B, the second slat 12b from the top has no through-holes, so there is no risk of light leakage by the second slat 12b. Further, neither the first lifting tape 15a nor the second lifting tape 15b is inserted into the slat 12b. According to the arrangement of the lifting tape 15, when the slat 12 tilts, the load on the slat 12 from the first lifting tape 15 a and the second lifting tape 15 b, particularly the load on the first and third slats 12. Therefore, all the slats 12 can be tilted smoothly.

As shown in FIG. 4, the first lifting tape 15 a has a proximal end fixed to the drum 17. The first lifting tape 15a passes from the head box 11 outside the uppermost slat 12a and the second slat 12b, and the third slat 12c between the second slat 12b and the third slat 12c. The first through hole 22 is inserted. The first lifting tape 15 a is inserted into the first through hole 22 with respect to the third and subsequent slats 12 c, and the tip ends are fixed to the both end portions of the bottom rail 14 by the tape holder 16.

The base end of the second lifting tape 15b is fixed to the drum 17. After the second lifting tape 15b is pulled out from the head box 11, the second lifting tape 15b is inserted into the second through hole 23 of the uppermost slat 12a, and the slat 12c is inserted between the uppermost slat 12a and the second slat 12b. Unwinds outside. The second lifting tape 15b extends in the ascending / descending direction along the warp 13a of the ladder cord 13 on the outside of the second long side portion 21b with respect to the third and subsequent slats 12c, and extends to the pico 13c of the ladder cord 13. The second lifting tape 15b is prevented from floating by being inserted. Note that the second lifting tape 15b need not be inserted through all the picos 13c. The tip of the second lifting tape 15 b is fixed to the center of the bottom rail 14 with a tape holder 16.

The uppermost slat 12a is provided with a slat retainer 24 at a position where the warp threads 13a of the three ladder cords 13 extend. The slat presser 24 is also provided at the position where the warp thread 13a of the ladder cord 13 on both sides of the slat 12b extends in the second slat 12b from the top. The slat retainer 24 suppresses lateral displacement of the slats 12 a and 12 b by engaging the weft thread 13 b of the ladder cord 13 in the long side portion of the slat 12. Further, the slat retainer 24 prevents the warp yarn 13a from repeatedly contacting the edge of the long side portion of the slats 12a and 12b, and the warp yarn 13a from being worn and cut. Furthermore, the slat retainer 24 suppresses deformation of the slat 12 by relaxing the load applied to the slat 12 from the warp 13a. Further, the slat retainer 24 reduces friction between the warp 13a and the slat 12, and allows the other slats 12 and 12c to follow the uppermost slat 12a and smoothly tilt. Even if this slat retainer 24 is provided in the third and subsequent slats 12c, the same effect can be obtained.

Next, the fully closed state of the slat 12 of the horizontal blind 10 configured as described above will be described with reference to FIGS. 6 and 7. In FIG. 7, the ladder code 13 is omitted.
When the slats 12 are in the fully closed state, the bottom rail 14 and the slats 12 are in a lowered state, and all the slats 12 are tilted in one direction and shielded from solar radiation. In this case, on the outside of the room, the second long side portion 21b of each slat 12 on the outside of the room faces downward. Generally, solar radiation is irradiated from above through a window. At this time, a gap between the slats 12 adjacent to each other is inclined from the bottom to the top from the outside of the room to the inside of the room. Therefore, the opening end of the gap outside the room faces downward and is difficult for solar radiation to enter, so that the light shielding property is improved.

At this time, the long side portions of the adjacent slats 12 overlap each other. For example, the second through hole 23 of the second long side portion 21b outside the room formed in the uppermost slat 12a is on the lower side, and the first inside the room located on the upper side of the second slat 12b from the top. The long side portion 21a is overlapped and shielded. Further, even in the first through holes 22 formed in the third and subsequent stages, they are shielded by the second long side portion 21b outside the room of the adjacent second slat 12b and the fourth and subsequent slats 12c. Is done. For example, the first through hole 22 of the third-stage slat 12c is located on the upper side and is shielded by the second long side portion 21b located on the lower side of the second-stage slat 12b from above. The first through holes 22 formed in the fourth and subsequent slats 12c are also located on the upper side, and are shielded by the second long side portion 21b on the lower side of the slats 12c adjacent to the upper side. Thus, the first through hole 22 and the second through hole 23 are shielded by the long side portion of the adjacent slat 12 when the slat 12 tilts in one direction and is fully closed. The horizontal blind 10 has improved light shielding properties by shielding the first through hole 22 and the second through hole 23 when the slat 12 is fully closed.

The horizontal blind 10 can tilt the slat 12 in the other direction so that the inclination of the slat 12 is opposite to that shown in FIGS. In this case, the first through hole 22 of the third slat 12c from the top is located on the lower side and is shielded by the second long side portion 21b located on the upper side of the fourth slat 12b from the top. However, the second through-hole 23 is not shielded because it is located on the upper side and there is no slat 12 thereon. Also in this case, the 2nd through-hole 23 becomes a shadow of the head box 11, and can reduce the incident solar radiation.

When lifting the bottom rail 14, the lifting tape 15 is wound around the drum 17. The second lifting tape 15b outside the room passes through the second through hole 23 of the uppermost slat 12a before being wound around the drum 17, so that it is substantially parallel to the main surface portion of the slat 12a. The flow is rectified to match the winding surface.

The first lifting tape 15a inside the room is also inserted into the first through hole 22 from the upper side to the third slat 12c below the slat 12a in which the second through hole 23 is formed, and the main surface portion of the slat 12c and It is almost parallel and corrected to a state corresponding to the winding surface of the drum 17. Therefore, the first lifting tape 15 a is also wound without being twisted by the winding surface of the drum 17. That is, the first lifting tape 15a and the second lifting tape 15b are wound around the drum 17 without being twisted. Therefore, the three drums 17 can wind up the same amount of the three lifting tapes 15a and 15b at the same speed, and can prevent the slats 12 from being tilted during winding.

The horizontal blind 10 as described above can obtain the effects listed below.
(1) Compared to a configuration in which a through hole through which the second lifting tape 15b is inserted is formed between the first through holes 22, the light shielding property is enhanced in the entire region where the light shielding property is particularly required.
(2) Since the long side portions overlap each other in the fully closed state, the first through hole 22 is blocked by the second long side portion 21b of the adjacent slat 12c, and light leakage from the first through hole 22 is suppressed.
(3) A second through hole 23 biased to the second long side portion 21b is formed in the longitudinal center of the uppermost slat 12a. When light leaks from the second through hole 23, However, the amount of light is small, and the overall light shielding performance is not significantly reduced.
(4) The second lifting tape 15 b passes through the second through hole 23 in the uppermost slat 12 a, so that the second lifting tape 15 b is adjusted to a state corresponding to the winding surface of the drum 17. Therefore, the drum 17 can wind the second lifting tape 15b without twisting the second lifting tape 15b.
(5) The first lifting tape 15 a is also adjusted to the state where the first lifting tape 15 a conforms to the winding surface of the drum 17 by passing through the first through hole 22 to the third-stage slat 12 c. Therefore, the first lifting tape 15a is also wound without being twisted.
(6) In the uppermost slat 12a, only the second lifting tape 15b is inserted through the second through hole 23, and the first through hole 22 through which the first lifting tape 15a is inserted is not formed. Therefore, the uppermost slat 12a can be tilted smoothly.
(7) The second lifting tape 15b is merely inserted through the second through hole 23 of the uppermost slat 12a, and the lower stage passes outside the slats 12b and slats 12c. Accordingly, when the second lifting tape 15b is in the fully closed state, the second lifting tape 15b does not contact the curved convex surface of each slat 12 to apply an extra load, and can smoothly tilt the slat 12.
(8) Since the second lifting tape 15b is inserted into the second through hole 23, the uppermost slat 12a can prevent lateral displacement of the slat 12a.
(9) Since the first lifting tape 15a is inserted through the first through hole 22 in the third and subsequent slats 12c, lateral displacement of the slats 12c can be prevented.

In addition, the horizontal blind 10 as described above can be implemented with appropriate modifications as follows.
-The 1st through-hole 22 in the both ends of the longitudinal direction of the slat 12 may be formed in a room outer side. The 2nd through-hole 23 in the center part of the longitudinal direction of the slat 12 may be formed in the room inner side, and may be omitted from the slat 12.
-The 1st through-hole 22 may be formed also in the uppermost slat 12a and the 2nd slat 12b, and one slat group may be comprised from all the slats 12. FIG.

The number of lifting tapes 15 and the number of ladder cords 13 are not limited to the above-described example. For example, the ladder cord 13 may be four and the lifting tape 15 may be four, or in a horizontally long horizontal blind, the ladder cord 13 may be seven and the lifting tape 15 may be four. Further, the ladder code 13 may be five and the lifting tape 15 may be three. That is, in any case, a plurality of second lifting tapes 15b may be provided between the first lifting tapes 15a located at both ends of the slat 12.

As described above, in the case of a horizontally-long horizontal blind, the number of ladder cords 13 is increased from three and the number of lifting tapes 15 is also increased from three as described above. Accordingly, the bottom rail 14 having the same length as the slat 12 is used.

In the example of FIG. 8, five ladder cords 13 and four lifting tapes 15 are used for a horizontally-long horizontal blind. Specifically, two first lifting tapes 15a are extended from the third and subsequent slats 12c to both ends in the longitudinal direction of the slats 12 inside the room. In addition, two second lifting tapes 15b extend between the two first lifting tapes 15a outside the room. In addition, you may make it use a thing with a width | variety wider than the width | variety between the long side parts of the slat 12 for the bottom rail 14, and to make it intensity | strength increase.

Also in the example of FIG. 8, the first lifting tape 15a is inserted into the first through hole 22 only at both ends of the slat 12c, and the second lifting tape 15b positioned between the first lifting tape 15a is as follows. The outside of the second long side portion 21b of the slat 12 is extended in the ascending / descending direction. Therefore, when the slat 12 is in the fully closed state, the light leakage is only from the surrounding first through-holes 22 and the overall light blocking performance can be improved.

The first through hole 22 through which the first lifting tape 15a located at both ends of the slat 12 is inserted may not be biased toward the first long side 21a inside the slat 12 inside the room. That is, the first through hole 22 may be biased toward the second long side portion 21b on the outside of the room. Furthermore, as shown in FIG. 9, the first through hole 22 may be provided at the center between the first long side portion 21 a and the second long side portion 21 b of the slat 12.

In this case, when the slat 12 is in the fully closed state, the first through hole 22 is not completely blocked by the slats 12 adjacent in the vertical direction. That is, the first through hole 22 is only partially blocked by the adjacent slats 12 or not entirely blocked depending on the position where it is provided. Even in this case, since the first through holes 22 are provided on both ends in the longitudinal direction, the entire structure is more than the case where the through holes for inserting the second lifting tape 15b are provided between the first through holes 22. The light-shielding property as can be improved.

As shown in FIG. 10, the second lifting tape 15b may extend to the first long side portion 21a and the second long side portion 21b of the slat 12c. In this case, the plurality of second lifting tapes 15b are respectively provided in the short direction of the slats 12, and are arranged so as to zigzag. A plurality of, here three, second lifting tapes 15b are arranged between the two second lifting tapes 15b. In this case, the 1st lifting tape 15a located in the both sides of the longitudinal direction of the slat 12c is penetrated by the 1st through-hole 22 provided in the both sides of the longitudinal direction of the slat 12c.

As shown in FIG. 11, the raising / lowering member for raising and lowering the bottom rail 14 is replaced with a tape-like thing such as a flat string, such as a first lifting tape 15a or a second lifting tape 15b, and a cord-like form such as a round string. It may be.

As shown in FIG. 12, more ladder cords 13 and lifting tapes 15 are used in an extremely horizontal horizontal blind. That is, in the example of FIG. 12, the 1st through-hole 22 is formed in the both ends side of the slat 12c, and the 1st lifting tape 15a is arrange | positioned. Further, between the ladder cords 13, every second lifting tape 15b is disposed. Note that the second lifting tape 15b may be disposed not only on the first long side portion 21a side but also on the second long side portion 21b side.

As shown in FIG. 13, the horizontal blind 10 is attached to the window frame 30 and shields the solar radiation of the light transmitting region 33 in the window frame 30. As a method of attaching the horizontal blind 10 to the window frame 30, first, there is a method shown in FIG. In FIG. 13, when the horizontal blind 10 covers the window frame 30 to reduce light leakage or hide the window frame 30, the horizontal blind 10 is attached to the curtain box 31 provided at the upper part of the window frame 30 inside the room with a ceiling. In this case, the horizontal length of the horizontal blind 10 is set to be longer than the interval A between the vertical frames 30 a and 30 a of the window frame 30. The height direction is also set longer than the interval B between the upper and lower horizontal frames 30b, 30b so that the bottom rail 14 is positioned below the lower horizontal frame 30b of the window frame 30. Thereby, the horizontal blind 10 covers the entire light-transmitting region 33 of the window frame 30.

In this case, the 1st lifting tape 15a inserted in the 1st through-hole 22 of the slat 12, and the 1st through-hole 22 is the position along the vertical frames 30a and 30a of the window frame 30, or the outer side of the vertical frames 30a and 30a. To position. In this case, light is not leaked from the first through hole 22, and the light shielding property can be enhanced. Even if the first through hole 22 is located inside the window frame 30 and is positioned close to the vertical frames 30a and 30a, the amount of light transmitted through the shadows of the vertical frames 30a and 30a is reduced. Can do.

Also, the bottom rail 14 is located below the lower horizontal frame 30b of the window frame 30. Therefore, if the second through hole 23 of the lowermost slat 12c or the slat 12c close to the lowermost slat 12c is located inside the lower horizontal frame 30b and is located close to the lower horizontal frame 30b, it is used. Since the light only enters the user's feet, it becomes inconspicuous for the user.

As shown in FIG. 14, the horizontal blind 10 may be attached to the inside of the window frame 30. In this case, the horizontal length of the horizontal blind 10 is set to be substantially the same as the interval A between the vertical frames 30 a and 30 a of the window frame 30. Also in the height direction, the length is set to be substantially the same as the interval B between the upper and lower horizontal frames 30b, 30b so that the bottom rail 14 is positioned on the lower horizontal frame 30b of the window frame 30. Thereby, the horizontal blind 10 covers the entire light-transmitting region 33 in the window frame 30.

In this case, the first through-hole 22 of the slat 12 and the first through-hole 22 through which the first lifting tape 15 a is inserted through the first through-hole 22 and the first through-hole 22 through the first through-hole 22 are the central portion of the translucent region 33. It is located near the vertical frame 30 a of the window frame 30, not a portion that stands out from the user. In particular, in the examples of FIGS. 9 to 12, the first through holes 22 are provided at both ends of the slat 12c in the longitudinal direction. Accordingly, the first through hole 22 is located near the vertical frame 30a. Even in the horizontal blind 10, the entire light-shielding property can be improved because no through hole is formed between the second through holes 23 of the slat 12.

Furthermore, in the case of FIG. 14, the second through holes 23 may be provided in several slats 12 close to the bottom rail 14. In such a case, the length of the horizontal blind 10 in the height direction is slightly longer than the interval B between the upper and lower horizontal frames 30b, 30b. Thereby, when the bottom rail 14 is descending, several slats overlap on the lower horizontal frame 30b, and the second through hole 23 is hidden. Therefore, the possibility of light leakage from the second through hole 23 can be suppressed.

[Second Embodiment]
First, with reference to FIG. 15 thru | or FIG. 22, the horizontal blind of 2nd Embodiment by this invention is demonstrated. FIG. 15 is a perspective view showing a schematic configuration of a horizontal blind according to the second embodiment of the present invention. FIG. 16 is a plan view of the slat s4 in the horizontal blind according to the second embodiment of the present invention. FIGS. 17A and 17B are explanatory views at the time of the tilting operation of the slat s4 in the horizontal blind according to the second embodiment of the present invention. 18 (a) and 18 (b) are explanatory diagrams when the slat s4 is shielded in the horizontal blind according to the second embodiment of the present invention. FIG. 19 is a side view showing a partial schematic configuration of a horizontal blind according to the second embodiment of the present invention. FIG. 20 is a partial side sectional view for explaining the shielding effect in the horizontal blind according to the second embodiment of the present invention. FIGS. 21A and 21B are a partial side sectional view for explaining the shielding effect in the horizontal blind according to the second embodiment of the present invention in more detail, and a comparative example thereof. 22 (a) and 22 (b) are plan views for explaining the lateral shift / twist suppression effect in the horizontal blind according to the second embodiment of the present invention.

As shown in FIG. 15, the horizontal blind according to the present embodiment is passed through ladder cords s7L, s7M, and s7R suspended from the left end side, the center side, and the right end side in the longitudinal direction of the head box s1, respectively. A multi-stage slat s4 is supported. A bottom rail s8 is suspended and supported at the lower end of each ladder cord s7L, s7M, s7R. In addition, the elevating cords s6L, s6M, and s6R that are three or more elevating members are suspended from the head box s1 in addition to the outdoor or indoor ladder cords s7L, s7M, and s7R. A bottom rail s8 is attached to the lower end.

A mechanism for adjusting the angles of the multi-stage slats s4, a mechanism for raising and lowering the multi-stage slats s4, and an operating means for operating these mechanisms can be realized in various known forms. Since it is not directly related to the gist of the present invention, an example thereof will be briefly described.

In the head box s1, ladder members s7L, s7M, and s7R and support members that suspend and support the lifting cords s6L, s6M, and s6R are disposed, and a square rod-shaped drive shaft is inserted through the support member (see FIG. Not shown). The tilt drum is rotatably supported by such a support member, and the drive shaft is inserted into the tilt drum so as not to be relatively rotatable. Therefore, when the drive shaft is rotated, the tilt drum is rotated, and the angles of the multi-stage slats s4 supported by the ladder cords s7L, s7M, and s7R are adjusted.

Further, in order to enable the lifting / lowering cords s6L, s6M, and s6R to be pulled into the head box s1 or to be pulled out from the head box s1, the support member is attached so as not to rotate relative to the drive shaft. A winding shaft is provided (not shown). Accordingly, when the drive shaft is rotated, the tilt drum rotates, and the angles of the multi-stage slats s4 supported by the ladder cords s7L, s7M, and s7R are tilted in a substantially vertical direction with respect to the horizontal direction. After that, the lifting / lowering cords s6L, s6M, and s6R are wound or rewound by the winding shaft, and the slat s4 can be lifted and lowered by raising and lowering the bottom rail s8.

An operation pulley for operating the rotation of the drive shaft is accommodated on the right end side of the head box s1, and an endless operation cord s5 hung on the operation pulley is provided on the front surface on the right end side of the head box s1. It hangs down from the provided outlet 1a. A stopper device capable of locking the rotation of the drive shaft is provided in the head box s1. Therefore, by operating the operation cord s5, the rotation of the drive shaft is operated, and the angles of the multi-stage slats s4 supported by the ladder cords s7L, s7M, s7R through the support members are adjusted. Alternatively, the multi-stage slats s4 can be moved up and down by the lifting cords s6L, s6M, and s6R.

In the horizontal blind according to the present embodiment, as shown in FIG. 16, among the plurality of lift cords s6L, s6M, and s6R, the lift cords s6L and s6R have one edge portion (outdoor edge portion) in the short direction of each slat s4. ) It is configured to be inserted and suspended through a long hole-like insertion hole s4a (through hole) provided in the vicinity and extending in the short direction, and for the lifting cord s6M, the other edge of each slat s4 in the short direction It is constituted so that it hangs along. The long hole-like insertion hole s4a is preferably formed so as to extend within a range from one edge portion (outdoor edge portion) of each slat s4 in the short direction to the center portion of each slat s4 in the short direction. It is. Each slat s4 is mounted on a weft thread s7a, s7b connected at a predetermined interval between a pair of ladder cords s7L (or s7M, s7R) that are arranged and suspended at a plurality of locations in the longitudinal direction of the head box s1. Each is supported.

In particular, the long hole-like insertion holes s4a do not hinder the tilting operation of the slats s4, and when the slats s4 are tilted so as to be in a shielding state, at least the insertion holes s4a at the edge of each slat s4. It is formed at a position where a part is shielded.

More specifically, as shown in FIG. 17, in order to insert the lifting / lowering cords s6L and s6R, a long hole-like insertion hole s4a is provided in the vicinity of the outdoor side edge in the short direction (that is, the front-rear direction) of each slat s4. , The lifting cords s6L and s6R are suspended when the slats s4 are in a horizontal state (see FIG. 17A) or tilted in the slats s4 (see FIG. 17B). It can be stretched without any burden in the vertical direction. In addition, since the long hole-like insertion hole s4a is provided in the vicinity of the outdoor edge, as shown in FIG. 17B, light leakage from the insertion hole s4a is suppressed and the light shielding property against external light is enhanced. Can do.

That is, as shown in FIG. 18 (a), the long hole-like insertion hole s4a extends from one edge portion (outdoor edge portion) of each slat s4 in the short direction to the center portion of each slat s4 in the short direction. When the slats s4 are shielded, the slats s4 are tilted in a substantially vertical direction with respect to the horizontal direction. At this time, at least one of the insertion holes s4a is formed at the edge of each slat s4. The part is shielded. As will be described later, the entire insertion hole s4a may be shielded by the edge of each slat s4. Thereby, the light leakage from the said insertion hole s4a can be suppressed, and the light-shielding property with respect to external light can be improved. Furthermore, by providing the insertion hole s4a in the vicinity of the outer edge of the outdoor space, the insertion hole s4a is lower in the fully closed state as shown in FIG. 18A (or FIG. 17B). Since it is almost hidden by the slat s4, the design is improved.

Further, as shown in FIG. 18B, it is preferable that the short diameter D of the long hole-shaped insertion hole s4a is formed to be substantially the same as the cross-sectional diameter d of the lifting cords s6L and s6R to be inserted. Thereby, even when the entire insertion hole s4a is not shielded by the edge of each slat s4, light leakage from the insertion hole s4a can be effectively suppressed. The “short diameter D of the insertion hole s4a substantially the same as the sectional diameter d of the lifting / lowering cords s6L and s6R” means a diameter that does not hinder the movement of the lifting / lowering cords s6L and s6R with respect to the insertion hole s4a. The diameter D is completely the same as the sectional diameter d, or the minor diameter D is slightly larger than the sectional diameter d. Further, by making the diameters of the ladder cords s7L and s7R substantially the same as the short diameter D of the long hole-shaped insertion hole s4a or a thickness larger than that, light leakage can be more reliably suppressed.

In addition, in addition to the three lifting / lowering cords s6L, s6M, and s6R as in the present embodiment, four or more lifting / lowering cords may be used. In this case, at least two lifting / lowering cords out of the plurality of lifting / lowering cords are inserted into the elongated hole-like insertion hole s4a and suspended, and at least one lifting / lowering cord other than the at least two lifting / lowering cords is lifted / lowered. The cord hangs along the other edge of each slat s4 in the short direction.

At this time, among the plurality of lifting cords, the lifting cords hanging down at the “most position from both ends” of each of the plurality of slats s4 (in the example of FIGS. 15 and 16, the lifting cords s6L, s6R) is configured to be inserted through a long hole-like insertion hole s4a extending in the short direction provided in the vicinity of one edge (outdoor edge) of each slat s4. All of the lifting / lowering cords (elevating cord s6M in the examples of FIGS. 15 and 16) inserted into the through-hole insertion hole s4a are not in the notch or the insertion hole, and the short direction of each slat s4 It is preferable to make it hang along the other edge (inner side edge). As a result, light leakage can be more effectively suppressed, and lateral displacement and twisting of the slat s4 can be suppressed as will be described in detail later.

In the horizontal blind of the present embodiment, each slat s4 is made of a flat hard material (for example, wooden), and the ladder cords s7L, s7M, s7R and the lifting / lowering cords s6L, s6R, s6M according to the slat s4 are disposed. Thus, it is possible to improve the assembling property while suppressing light leakage, and to effectively suppress the lateral displacement and twisting of the slats.

As shown in FIGS. 15 and 16, a pair of ladder cords s7L, s7M, and s7R are suspended opposite to each other in the short direction (ie, the front-rear direction) of the slat s4, and between the pair of ladder cords s7L, Weft yarns s7a and s7b intersecting in an X shape are connected at predetermined intervals, and as shown in FIG. 19, a slat s4 is placed on the weft yarns s7a and s7b. Similarly, between the pair of ladder cords s7M (or s7R), weft threads s7a and s7b intersecting in an X shape are connected at a predetermined interval, and a slat s4 is placed on the weft threads s7a and s7b.

In a general horizontal blind, there is a form using a slat having a slightly curved thin plate shape made of a flexible material made of aluminum, and when using such a bendable slat, Since it is possible to relatively easily insert the slat between the wefts s7a and s7b intersecting in an X shape by using the flexibility, the assembling property does not become a great burden. Further, in the conventional horizontal blind, the lateral displacement of the slat may be suppressed by engaging the ladder cord, not the lifting / lowering cord, with the notch of the slat.

On the other hand, as shown in FIGS. 15 and 19, the slat s4 in the horizontal blind of the present embodiment has a flat plate shape made of a hard material such as wood that cannot be bent. It cannot be said that it is easy to assemble the flat slat s4 made of a hard material while being inserted between the wefts s7a and s7b intersecting in the X shape. For this reason, in the horizontal blind of this embodiment, it is possible to improve the assemblability by configuring the flat slats s4 made of this hard material on the wefts s7a and s7b intersecting with the X shape. . Further, the slat s4 in the horizontal blind according to the present embodiment is not provided with a notch that is engaged with the weft threads s7a and s7b of the ladder cords s7L, s7M, and s7R. Installation of the ladder cords s7L, s7M, and s7R on the weft threads s7a and s7b is also facilitated.

Normally, when a flat slat s4 is simply placed on the weft threads s7a and s7b without providing a notch, the lateral displacement of each slat s4 in the longitudinal direction (that is, the left-right direction) or the short direction of each slat s4 ( That is, a twist that acts in the front-rear direction occurs, and a malfunction may occur during the raising / lowering operation or tilting operation of the slat s4. However, in the horizontal blind according to the present embodiment, such a lateral shift and twist can be suppressed.

That is, in the horizontal blind according to the present embodiment, as shown in FIGS. 15 and 16, ascending / descending cord s6L suspended from the head box s1 at the nearest position from both ends in the longitudinal direction (that is, left and right direction) of each slat s4. , S6R are inserted through a long hole-like insertion hole s4a in the front-rear direction provided in the vicinity of the outdoor side edge of each slat s4 in the short direction (that is, the front-rear direction), and the outdoor side on the upper surface of the bottom rail s8. It engages and attaches to the bottom side through the through portions s8L and s8R provided in the vicinity of the edge. And, at least one of the lifting / lowering cords other than the lifting / lowering cords s6L and s6R hanging from the both ends in the longitudinal direction (that is, the left / right direction) of each slat s4 (that is, the lifting / lowering cord s6M in this example). Hangs along the indoor side edge of each slat s4 in the short direction (that is, the front-rear direction), and engages with a mounting portion s8M provided on the bottom surface along the front side surface of the bottom rail s8. To do. That is, a plurality of lifting / lowering cords can be suspended between the lifting / lowering cords s6L and s6R, but at least one of the lifting / lowering cords is configured to hang along the indoor side edge.

In the horizontal blind according to the present embodiment configured as described above, light leakage from the insertion hole s4a is suppressed by shielding at least a part of the insertion hole s4a at the edge of each slat s4 as shown in FIG. More preferably, the entire insertion hole s4a is configured to be shielded by the edge of each slat s4. Thereby, the light leakage from the said insertion hole s4a can be suppressed reliably, and the light-shielding property with respect to external light can be improved. For example, as shown in FIG. 20, since the slat s4 in the present embodiment is thick, in order to hide all of the insertion holes s4a during tilting (when fully closed), the position of the upper end sA of the lower slat s4 is The insertion hole s4a is formed so as to be at a position that is horizontal with or higher than the position of the upper edge sB of the insertion hole s4a of the upper slat s4. At this time, the lifting / lowering cord s6R (or s6L) may be slightly loosened as shown in FIG.

Further, by providing the insertion hole s4a in the vicinity of the outdoor edge of the slat s4, the shielding property at the time of tilting (when fully closed) can be improved. For example, when the insertion hole s4a is provided in the vicinity of the outdoor edge of the slat s4 as in the present embodiment shown in FIG. Since the lifting / lowering cord s6R (or s6L) and the ladder cord s7R (or s7L) do not hinder the tilting operation of the slat s4, the shielding performance is improved. On the other hand, when the insertion hole s4a is provided in the vicinity of the indoor side edge of the slat s4, as shown in FIG. Since the tilt operation of the slat s4 can be hindered, the shielding performance may be adversely affected. Therefore, by providing the insertion hole s4a in the vicinity of the outdoor edge of the slat s4, it is possible to improve the shielding performance at the time of tilting (when fully closed).

Thus, by providing the insertion hole s4a in the slat s4 and arranging the plurality of lifting cords s6L, s6R, s6M as shown in FIG. 16, each slat s4 simply placed on the weft s7a, s7b can be provided. As shown in FIGS. 20 and 21, the lateral displacement (see FIG. 22 (a)) and twist (see FIG. 22 (b)) can be suppressed while improving the shielding performance during tilting (when fully closed). Become.
