Description

The present invention relates to horizontal blinds.

Various types of horizontal blinds having a plurality of plate-shaped rotatable slats have been proposed. A ladder cord and an elevating cord are attached to the slats of the horizontal blind (see, for example, Patent Document 1). The ladder code operates according to the operation of the operation code, and the slats rotate. In addition, the elevating cord also moves up and down with the operation of the operation unit, and the slats slide and move.

In the horizontal blind of Patent Document 1, a notch is formed at the leading edge of the slats at a position corresponding to the arrangement position of the warp threads of the ladder cord. In Patent Document 1, when this notch is formed in a slat, the warp on the front side of the ladder cord fits in the notch. As a result, the displacement of the slats in the lateral direction (longitudinal direction of the slats) is suppressed.

Further, in the horizontal blind of Patent Document 1, a guide ring is provided on the warp on the front side of the ladder cord. An elevating cord is passed through the guide ring to avoid problems such as the elevating cord getting entangled with the ladder cord and improving the descent of the slats.

Hereinafter, embodiments of the present invention will be described. The various features shown in the embodiments shown below can be combined with each other. In addition, the invention is independently established for each feature.

1 Overall Configuration As shown in FIGS. 1 to 5, the horizontal blind 10 is provided with a loop-shaped operation code 15 hanging from a head box 11 installed in a building or the like. The operation code 15 is a ball chain in the embodiment, but the operation code 15 is not limited thereto. The horizontal blind 10 includes a plurality of slats 12 extending in the horizontal direction. Then, in a state where the plurality of slats 12 are lowered from the head box 11, the plurality of slats 12 are provided so as to be arranged in the vertical direction as shown in FIG.

The horizontal blind 10 includes a head box 11, a plurality of slats 12, an elevating cord 3, a ladder cord 4, a bottom rail 14, and an operation cord 15.

The head box 11 includes a bracket 5, a pulley 6, a power transmission device 7, a speed adjusting unit 8, an elevating shaft 16A, a tilt shaft 16B, and a support member 1 (see FIGS. 3 and 5). There is.

The bracket 5 is fixed to an attached body such as an upper frame of a window. As a result, the horizontal blind 10 is fixed to the attached body. A pulley 6 on which the operation code 15 is mounted is provided in the head box 11. A power transmission device 7 is provided in the head box 11. The power transmission device 7 is connected to the elevating shaft 16A and the tilt shaft 16B. The power transmission device 7 has a function of transmitting the rotation of the pulley 6 to the elevating shaft 16A and the tilt shaft 16B to rotate the elevating shaft 16A and the tilt shaft 16B. The elevating shaft 16A is connected to the speed adjusting unit 8. The speed adjusting unit 8 has a function of adjusting the torque acting on the elevating shaft 16A, and can reduce the descending speed of the slat 12 and the bottom rail 14.

The slats 12 are suspended and supported by the head box 11. Specifically, the ladder cord 4 includes a pair of warp threads and a plurality of weft threads sandwiched between them, and the slats 12 are supported by each weft thread. The ladder cord 4 is suspended from the tilt drum 30, and is displaced by the rotation of the tilt drum 30, so that the slats 12 rotate.

The elevating cord 3 is pulled out from the head box 11. The upper end side of the elevating cord 3 is attached to the winding shaft 23 of the support member 1, and the elevating cord 3 can be wound and rewound on the winding shaft 23 (see FIG. 5). A bottom rail 14 is attached to the lower end side of the elevating cord 3. When the elevating cord 3 is wound around the take-up shaft 23, the slat 12 rises together with the bottom rail 14, and when the elevating cord 3 is rewound on the take-up shaft 23, the slat 12 descends together with the bottom rail 14.

The front warp and the rear warp of the ladder cord 4 are drawn out from the head box 11, respectively. The ladder code 4 is attached to the tilt drum 30, and the ladder code 4 is configured to be displaceable following the rotation of the tilt drum 30 (see FIG. 5). That is, when the tilt drum 30 is viewed from the right side surface, for example, when the tilt drum 30 rotates counterclockwise, the front warp threads are displaced so as to be pulled out downward, and the rear warp threads are displaced so as to be pulled back upward. As a result, the slat 12 rotates so that its front end faces downward. If the tilt drum 30 rotates in the opposite direction, the slat 12 rotates so that its front end faces upward.

2. 2. Detailed Configuration Description As shown in FIG. 8, the elevating cord 3 includes a first elevating cord 31 and a second elevating cord 32, and the ladder code 4 includes a first ladder code 41 and a second ladder code 42. In other words, the horizontal blind 10 includes a set of the first elevating cord 31 and the first ladder code 41, and two sets of the second elevating cord 32 and the second ladder code 42.

2-1. Slat 12
As shown in FIGS. 10A to 10D, the slats 12 have an arcuate vertical cross-sectional shape, and the slats 12 extend parallel to the longitudinal direction of the headbox 11. The slats 12 are suspended from the first ladder cord 41 and the second ladder cord 42, and the slats 12 rotate with the displacement of the first ladder cord 41 and the second ladder cord 42. In the uppermost slat 12, the weft thread 41B is fixed to the slat 12 by the slat retainer 9. Further, the slats 12 are provided in a plurality of stages in the vertical direction together with the weft threads 41B and the weft threads 42B described later.

As shown in FIGS. 6 and 8, a first elevating cord 31 and a first ladder cord 41 are arranged at the center of the slats 12 in the longitudinal direction. A second elevating cord 32 and a second ladder cord 42 are arranged on the left end side and the right end side of the slat 12 in the longitudinal direction, respectively.

As shown in FIG. 10B, the slat 12 is formed with a leading edge portion 12a and a trailing edge portion 12b. The leading edge 12a corresponds to the first edge and the trailing edge 12b corresponds to the second edge. The leading edge 12a and the trailing edge 12b extend parallel to the longitudinal direction of the slat 12. As shown in FIGS. 10A to 10D, one first cutout portion 12A and two second cutout portions 12B are formed in the trailing edge portion 12b. Since the front edge portion 12a is located on the front side of the horizontal blind 10 and is easily noticed by human eyes, the first and second notches 12A and 12B described above are not formed on the front edge portion 12a.

As shown in FIGS. 10A and 10B, the first notch 12A is formed in the central portion of the slat 12 in the longitudinal direction. As shown in FIG. 9A, the leading edge portion 12a of the slat 12 faces the first elevating cord 31 and faces the front warp 41A1 of the first ladder cord 41. In other words, the first elevating cord 31 and the front warp 41A1 of the first ladder cord 41 are located in front of the leading edge portion 12a of the slat 12. The first notch 12A faces the rear warp 41A2 of the first ladder cord 41. In other words, the rear warp 41A2 of the first ladder cord 41 is located behind the first notch 12A.

As shown in FIGS. 10A, 10B and 10D, one of the two second notches 12B is formed on one end side of the slat 12 in the longitudinal direction, and the other of the two second notches 12B is formed. , Is formed on the other end side of the slats 12 in the longitudinal direction. That is, a first notch 12A is formed between the two second notches 12B. As shown in FIG. 9B, the leading edge portion 12a of the slat 12 faces the front warp 42A1 of the second ladder cord 42. In other words, the front warp 42A1 of the second ladder cord 42 is located in front of the leading edge 12a of the slat 12. The second notch portion 12B faces the second elevating cord 32 and faces the rear warp 42A2 of the second ladder cord 42. In other words, the rear warp 42A2 of the second elevating cord 32 and the second ladder cord 42 is located behind the second notch 12B.

As described above, the slat 12 is formed with a first notch 12A and a second notch 12B. The rear warp 41A2 of the first ladder cord 41 is located behind the first notch 12A, and the rear side of the second elevating cord 32 and the second ladder cord 42 is behind the second notch 12B. The warp 42A2 is located. Therefore, when the slat 12 tries to move in the lateral direction (longitudinal direction of the slat 12), the first notch 12A is caught by the first rudder cord 41, and the second notch 12B is the second elevating cord 32 and the second ladder. It gets caught in the code 42. As described above, the first notch portion 12A and the second notch portion 12B have a lateral slip prevention function of the slat 12.

2-2. 1st elevating cord 31 and 1st ladder code 41
The upper end of the first elevating cord 31 is attached to the take-up shaft 23, and the lower end of the first elevating cord 31 is attached to the bottom rail 14. As shown in FIG. 9A, the first elevating cord 31 is located in front of the leading edge portion 12a of the slat 12. The first elevating cord 31 is provided along the front warp 41A1 of the first ladder cord 41.

As shown in FIG. 9A, the first ladder cord 41 includes a front warp 41A1 and a rear warp 41A2, and a pair of weft 41Bs. The front warp 41A1 and the rear warp 41A2 correspond to a pair of first warp threads. The pair of weft threads 41B correspond to a pair of first weft threads. The upper end of the front warp 41A1 and the upper end of the rear warp 41A2 are attached to the tilt drum 30, and the lower end of the front warp 41A1 and the lower end of the rear warp 41A2 are attached to the bottom rail 14.

When the horizontal blind 10 is viewed from the right side or the left side, the pair of weft threads 41B intersect with each other. One end of each weft 41B is attached to the front warp 41A1, and the other end of each weft 41B is attached to the rear warp 41A2. A plurality of pairs of weft threads 41B are provided on the front warp threads 41A1 and the rear warp threads 41A2 so as to be arranged in the vertical direction.

As shown in FIG. 6, the slats 12 are inserted between the pair of weft threads 41B. In a state where the slats 12 are inserted between the pair of weft threads 41B, the slats 12 are arranged between the front warp threads 42A1 and the intersection position Cp1 where the pair of weft threads 41B intersect with each other. As a result, the displacement of the slats 12 in the front-rear direction is suppressed.

Further, as shown in FIG. 6, the first elevating cord 31 is inserted between the pair of weft threads 41B, and the first elevating cord 31 is guided by the pair of weft threads 41B. Here, in the embodiment, unlike the conventional horizontal blind, a guide ring arranged in front of the horizontal blind is provided, and a configuration in which an elevating cord is passed through the guide ring is not adopted. Therefore, the horizontal blind 10 according to the embodiment has an improved design while having a function of guiding the first elevating cord 31. The first elevating cord 31 is passed through the weft 42B corresponding to the slat 12 in the third and subsequent stages from the top. That is, the first elevating cord 31 is inserted through each weft thread 41B from the third step to the bottom step from the top.

The first elevating cord 31 is inserted through the weft thread 41B in the third step from the top, while the second elevating cord 32 is inserted through the weft thread 42B in the second step from the top. When the first elevating cord 31 is inserted through the weft thread 41B of the first or second step from the top in the central portion in the longitudinal direction of the slat 12, when the slat 12 is closed (when the slat 12 is upward). , The front warp 42A1 may be pulled by the first elevating cord 31, the angle of the slat 12 may be tilted to the horizontal side, and light may leak. In order to prevent light from leaking at the central portion of the slats 12, the first elevating cord 31 is inserted through the weft thread 41B in the third step from the top.

2-3. 2nd lifting cord 32 and 2nd ladder cord 42
The upper end of the second elevating cord 32 is attached to a take-up shaft 23 different from the take-up shaft 23 attached to the first elevating cord 31. Further, the lower end portion of the second elevating cord 32 is attached to the bottom rail 14. As shown in FIG. 9B, the second elevating cord 32 is located behind the trailing edge 12b of the slat 12. The second elevating cord 32 is provided along the rear warp 42A2 of the second ladder cord 42.

As shown in FIG. 9B, the second ladder cord 42 includes a front warp 42A1 and a rear warp 42A2, and a pair of weft 42Bs. The front warp 42A1 and the rear warp 42A2 correspond to a pair of second warp threads. The pair of weft threads 42B correspond to a pair of second weft threads. The upper end of the front warp 42A1 and the upper end of the rear warp 42A2 are attached to a tilt drum 30 different from the tilt drum 30 to which the first ladder cord 41 is attached. The lower end of the front warp 42A1 and the lower end of the rear warp 42A2 are attached to the bottom rail 14.

When the horizontal blind 10 is viewed from the right side or the left side, the pair of weft threads 42B intersect with each other. One end of each weft 42B is attached to the front warp 42A1, and the other end of each weft 42B is attached to the rear warp 42A2. A plurality of pairs of weft threads 42B are provided on the front warp threads 42A1 and the rear warp threads 42A2 so as to be arranged in the vertical direction.

As shown in FIG. 7, the slats 12 are inserted between the pair of weft threads 42B. In a state where the slats 12 are inserted between the pair of weft threads 42B, the slats 12 are arranged between the front warp threads 42A1 and the intersection position Cp2 where the pair of weft threads 42B intersect with each other. As a result, the displacement of the slats 12 in the front-rear direction is suppressed.

As shown in FIG. 7, the second elevating cord 32 is inserted between the pair of weft threads 42B. The second elevating cord 32 is inserted into the weft 42B of the second and subsequent steps from the top. That is, the second elevating cord 32 is inserted through each weft thread 42B from the second step to the bottom step from the top. Here, as shown in FIGS. 11 to 13, the portion of the second elevating cord 32 inserted between the pair of weft threads 42B is formed from the second notch 12B of the trailing edge portion 12b of the slat 12. 2 It is movable between the rear warp 42A2 of the ladder cord 42. That is, when the horizontal blind 10 is viewed from the right side or the left side, the pair of weft threads 42B intersect each other as described above, but when the horizontal blind 10 is viewed from the upper side or the lower side, the pair of weft threads 42B intersect each other. Absent. Therefore, as shown in FIGS. 11 to 13, the second elevating cord 32 can pass through the crossing position Cp2 without being caught by the weft 42B at the crossing position Cp2. In other words, the second elevating cord 32 has a wide movable range in the front-rear direction. Therefore, when the slat 12 is descending by its own weight, the interference between the second elevating cord 32 and the trailing edge portion 12b of each slat 12 is suppressed, and as a result, the slat 12 is more reliably lowered to a desired position. ..

3. 3. Operation explanation The pulling operation of the slat 12 will be described. Here, in the state before the pulling operation, it is assumed that the bottom rail 14 is located at the lowest point and the slats 12 are oriented horizontally. Further, the rotation directions of the various configurations will be described with reference to the case where the horizontal blind 10 is viewed from the right side.

When the operator starts pulling down the front side portion 15A (see FIG. 2) of the operation cord 15, the rotational force of the pulley 6 is transmitted to the tilt shaft 16B via the power transmission device 7 shown in FIGS. 3 and 4. On the other hand, the rotational force of the pulley 6 is not transmitted to the elevating shaft 16A at this stage. That is, the elevating shaft 16A operates with a delay with respect to the tilt shaft 16B. The tilt shaft 16B rotates counterclockwise, and the orientation of the slats 12 shifts from parallel to downward. When the slat 12 faces downward, the elevating shaft 16A starts rotating, and the bottom rail 14 and the slat 12 rise.

Next, the pulling operation of the slat 12 will be described. In the state before the pulling operation, it is assumed that the bottom rail 14 is located at the uppermost point and the slat 12 is facing downward.

When the operator starts pulling down the rear portion 15B (see FIG. 2) of the operation cord 15, the rotational force of the pulley 6 is transmitted to the tilt shaft 16B via the power transmission device 7 shown in FIGS. 3 and 4. .. At this stage, the rotational force of the pulley 6 is not transmitted to the elevating shaft 16A as in the pulling operation. The tilt shaft 16B rotates clockwise, and the orientation of the slat 12 shifts from downward to upward accordingly. When the slat 12 is turned upward, the clutch of the power transmission device 7 is then disengaged, and the elevating shaft 16A starts rotating clockwise due to the weight of the bottom rail 14 or the like, and the slat 12 is lowered accordingly. That is, the bottom rail 14 and the slats 12 descend by their own weight.

When the slat 12 is descending by its own weight, the slat 12 is in a state of being easily laterally displaced. Here, in the horizontal blind 10 according to the embodiment, since the first notch 12A is formed in the slat 12, the rear warp 41A2 of the first ladder cord 41 is the first when the slat 12 is descending by its own weight. It fits in one notch 12A. Therefore, when the slat 12 is descending by its own weight, the slat 12 is prevented from laterally shifting. Further, since the first notch portion 12A is formed in the trailing edge portion 12b of the slats 12, the design of the horizontal blind 10 is improved.
Further, in the horizontal blind 10 according to the embodiment, the first elevating cord 31 is passed through a pair of weft threads 41B of the first ladder cord 41. Therefore, when the slat 12 descends by its own weight, the front warp 41A1 of the first ladder cord 41 and the first elevating cord 31 are prevented from being separated from each other. That is, since the first ladder code 41 and the first elevating code 31 are put together, the design of the horizontal blind 10 is improved by that amount.

In the embodiment, as shown in FIGS. 15A and 16A, when the slat 12 is pulled up, the slat 12 is tilted so that the leading edge 12a is located below the trailing edge 12b. That is, in the embodiment, when the operation code 15 is operated, the tilt operation and the elevating operation are sequentially performed by the action of the power transmission device 7. When the operator pulls up the bottom rail 14 (slat 12) from the lowest point, the operator pulls down the front side portion 15A of the operation cord 15, so that the leading edge portion 12a of the slats 12 is lower than the trailing edge portion 12b. Rotate so that it is located at. At this time, the bottom rail 14 (slat 12) has not yet risen. When the operator keeps pulling down the front side portion 15A of the operation code 15, the rotation operation of the slat 12 is completed and the slat 12 is raised. As described above, in the embodiment, when the slat 12 is pulled up, the slat 12 is tilted so that the leading edge portion 12a is located below the trailing edge portion 12b. At this time, as shown in FIGS. 15B and 16B, the weft thread 41B is caught in the first notch portion 12A, and the weft thread 42B is caught in the second notch portion 12B. Therefore, the lateral displacement of the slat 12 when the slat 12 rises is effectively suppressed.

Further, the rotational torque generated in the elevating shaft 16A is adjusted by the speed adjusting unit 8. Specifically, the speed adjusting unit 8 is configured so that the descending speed of the bottom rail 14 decreases as the bottom rail 14 approaches the lowest point. Therefore, as shown in FIG. 14, among the slats 12, the lower slats 12L (slats 12 closer to the bottom rail 14) are compared with the upper slats 12U (slats closer to the headbox 11), and the second elevating cord Due to the interference with 32, it is difficult to descend properly. However, in the embodiment, as described above, the second elevating cord 32 has a wide movable range in the front-rear direction. Therefore, when the slat 12 is descending by its own weight, the interference between the second elevating cord 32 and the trailing edge portion 12b of each slat 12 is suppressed, and as a result, the slat 12 is more reliably lowered to a desired position. ..

4. Other Embodiments In the embodiment, the power transmission device 7 has a clutch function, and the slats 12 can be automatically lowered, but the present invention is not limited to this. The operator may continue to pull down the operation code 15 to lower the slat 12. In this case, the speed adjusting unit 8 is unnecessary. In this modification, when the operator operates the operation code 15 to lower the slat 12, the operator does not need to apply an extra force and can smoothly lower the slat 12.

The present embodiment is provided with a pair consisting of an elevating cord and a ladder cord, but the present embodiment is not limited to this, and a configuration that does not form a pair may be separately provided. For example, as shown in FIG. 17, the horizontal blind may have a portion provided with only the ladder code 43. The ladder cord 43 includes a front warp 43A1, a rear warp 43A2, and a pair of weft 43Bs. In the case of this modification, the slat 12 is not inserted between the pair of weft threads 43B, and the slat 12 is placed on the pair of weft threads 43B. Even in this modified example, it has the same effect as that of the embodiment.

The present embodiment can also be applied to the electric horizontal blind 10 shown in FIG. The electric horizontal blind 10 does not include an operation code or a pulley on which the operation code is mounted, but includes an electric power unit (not shown) composed of a motor or the like. The electric power unit is mounted in the head box 11 and can drive the elevating shaft and the tilt shaft. Even in this modified example, it has the same effect as that of the embodiment.
