JP 2016-33323 A

  In the horizontal blind of Patent Document 1 described above, the lifting / lowering cord is suspended through the insertion hole of the slat. Further, a dummy cord is suspended through the insertion hole of the slat to prevent the lateral displacement of the slat. For this reason, when the light from the window is shielded in the fully closed state by tilting the slat, there is a problem that the light leaks into the room through the insertion hole.

  This invention is made | formed in view of such a background, and makes it a subject to provide the horizontal blind which can suppress light leakage, when light is shielded with a slat.

  In order to solve the above-described problems, a horizontal blind according to the present invention includes a horizontal slat supported by a head box via a ladder cord, and a vertical cord that is suspended from the head box and lifts and lowers each slat. A blind, wherein the slat includes a recess at a longitudinal end of the slat, and the lifting cord is suspended from the longitudinal end of the head box through the recess. To do.

  According to this structure, since the recessed part is provided in the edge part of the slat, the influence of light leakage can be suppressed compared with providing an insertion hole near the center of the slat in the longitudinal direction. Further, an elevating cord passes through a recess provided on both ends of the slat, and this elevating cord is provided by being pulled by the bottom rail. For this reason, even if the slat tries to move in the longitudinal direction, the end portion of the slat contacts the lifting cord, and the movement is suppressed. Furthermore, since the lifting / lowering cord passes through the recess, the lifting / lowering cord is prevented from being displaced from the end portion of the slat.

  According to this configuration, the elevating cord can be easily passed through the recess.

  Further, the concave portion is characterized in that the opening width of the inlet portion that opens is larger than the diameter of the elevating cord.

  According to this configuration, if the opening width of the recess is significantly larger than the diameter of the cord or the lifting / lowering cord, the cord or the lifting / lowering cord can easily pass through the recesses at both ends of each slat. Further, when the slat is erected, the opening width of the concave portion is significantly larger than the diameter of the lifting / lowering cord, so that the slat stands substantially straight in the vertical direction in a state where the lifting / lowering cord hangs substantially straight. For this reason, there is no gap between the slats because the slats standing in the vertical direction are not pushed and bent in the crank shape by the front and rear elevating cords above and below the insertion hole as in the prior art. Therefore, light leakage can be suppressed.

  Moreover, the said recessed part becomes a shape where the both ends of the longitudinal direction of the said slat curved in the circular arc shape.

  Moreover, the said recessed part becomes a shape where the both ends of the longitudinal direction of the said slat curved in the shape of a dogleg.

  According to these configurations, since the concave portion has an arc shape or a dogleg shape, the cord or the lifting / lowering cord can be easily passed. In addition, when the slat is erected, since the concave portion has an arc shape or a square shape, the slat stands substantially straight in the vertical direction in a state where the lifting / lowering cord hangs substantially straight. For this reason, there is no gap between the slats because the slats standing in the vertical direction are not pushed and bent in the crank shape by the front and rear elevating cords above and below the insertion hole as in the prior art. Therefore, light leakage can be suppressed.

  A holding member that is attached to an end of the slat in the longitudinal direction and holds the lifting cord; the holding member extending in a short direction of the slat; A claw portion provided at an end portion in the short-side direction and an insertion hole formed through the main body portion, the insertion hole is disposed in the recess, and the holding member is attached to the slat by the claw portion. Assembling, the elevating cord is inserted into the insertion hole and the recess.

  According to this configuration, when the plate-like member is assembled to both end portions of the slat, the strength of the end portion of the slat increases, and bending or the like can be prevented. Moreover, since the lifting / lowering cord passes through the insertion hole, the lifting / lowering cord does not come off.

  A horizontal type comprising a plurality of slats supported by a head box via ladder cords, a lifting cord suspended from the head box and elevating each slat, and a lateral slip prevention cord for preventing lateral displacement of the slat. The blind is characterized in that a concave portion is provided at an end portion in the longitudinal direction of the slat, and the concave portion has a shape into which the lateral displacement prevention cord is fitted and inserted.

  According to this configuration, even when the slat is fully closed, light leakage can be suppressed from the concave portion of the slat through which the lateral slip prevention cord is inserted.

  In the horizontal blind according to the present invention, light leakage can be suppressed when light is shielded by slats.

<Configuration of First Embodiment>
A first embodiment of the present invention will be described in detail with reference to the drawings as appropriate.

  FIG. 1 is a front view showing a configuration of a horizontal blind according to the first embodiment of the present invention.

  A horizontal blind 10 shown in FIG. 1 includes a head box 11, two ladder cords 12, a bottom rail 13, a plurality of slats 14, two lift cords 15, and an operation unit 17 for the lift cord 15. The tilt pole 18 is provided.

  In the horizontal blind 10, ladder cords 12 are suspended from both sides of the head box 11, and a bottom rail 13 is attached to the lower end of the ladder cord 12. On the ladder cord 12, slats 14 extending in the horizontal direction are supported by being arranged in a plurality of stages in the vertical direction. That is, as shown in FIG. 2A, the ladder cord 12 is composed of two warp yarns 12 and two weft yarns 12a and 12b that intersect between the warp yarns 12, and the two weft yarns 12a. , 12b, slats 14 are inserted and supported.

  Concave portions 14 a are formed at both ends of the slat 14 in the longitudinal direction. The recess 14a is shown in an enlarged manner in FIG. In the recess 14a, the lifting / lowering cords 15 hanging from the both ends of the head box 11 along the both ends of each slat 14 pass vertically. The lifting / lowering cord 15 is in a separated state from the slat 14 in the recess 14a when each slat 14 is stationary.

  As shown in FIG. 1, the lifting cords 15 on both sides are suspended on one side through rollers 16 that are rotatably attached to both ends of the head box 11. The other side of the lifting / lowering cord 15 passing through the roller 16 is inserted into the internal space 11b of the head box 11 shown in FIG. As shown in FIG. 1, the inserted lifting / lowering cords 15 are led out to the outside through an opening 11 a provided through the front wall of the head box 11, and the leading end side thus led is fixed to the operation unit 17. Has been. The opening 11a is provided with a stopper function (not shown) for fixing the lifting / lowering cord 15 during the lifting / lowering operation. The roller 16 may be a fixed type that is not rotatable, and may be any member that restricts the lifting / lowering cord 15 to hang down from both ends of the bottom rail 13.

  The lower end of the lifting / lowering cord 15 that hangs down along both ends of each slat 14 is fixed to the bottom rail 13. A fixing structure of one end portion of both ends of the bottom rail 13 is shown in a sectional view of FIG. 4A and a perspective view of FIG. As shown in FIG. 4, the bottom rail 13 has a rectangular tube shape having a cavity 13c therein, and caps 13p are attached to both ends thereof. The cap 13p has a curved portion 13a that is curved downward, and a concave portion 13b is formed at an upper end portion of the curved portion 13a. A through hole 13d is formed in the bottom surface of the bottom rail 13 near the cap 13p of the cavity 13c.

  The lower end side of the lifting / lowering cord 15 is inserted into the through-hole 13d while being in contact with the curved portion 13a through the concave portion 13b of the cap 13p. The tip of the inserted lifting / lowering cord 15 is connected to a round knot 15a larger than the through hole 13d in the cavity 13c, and is fixed so as not to come out of the through hole 13d.

  Further, a tilt pole 18 is attached to the right outer surface of the head box 11 shown in FIG. 1 in the vertical direction. The upper end side of the tilt pole 18 is connected to the ladder cord 12 through a plurality of rotation mechanism portions 18b connected by a tilt shaft 18a inside the head box 11. By rotating the tilt pole 18 to the left and right, the two warp yarns 12 of the ladder cord 12 are moved up and down in opposite directions by the rotating mechanism portion 18b connected by the tilt shaft 18a. It turns to the state or the vertical state with respect to the horizontal. At this time, when the slat 14 is fully rotated toward the vertical state, the slat 14 is fully closed, and when the slat 14 is fully rotated toward the horizontal state, the slat 14 is fully opened.

  In the horizontal blind 10 having such a configuration, when the operation unit 17 is grasped and lowered by a person, the elevating cord 15 is pulled upward, and each slat 14 and the bottom rail 13 supported by the ladder cord 12 are moved. To rise. The lifting / lowering cord 15 is fixed by a stopper function by releasing the operation unit 17 at an arbitrary raised position. After the fixing, when the operating portion 17 is pulled slightly and loosened, the lifting / lowering cord 15 is fixed. After the release, when the force for pulling the operating portion 17 downward is released or weakened, the elevating cord 15 extends downward and the slats 14 and the bottom rail 13 are lowered.

  During such ascending / descending, the elevating cord 15 passes through the recesses 14a on both ends of each slat 14 and is fixed to the bottom rail 13, so that the slat 14 is prevented from shifting laterally, and the slat 14 is smooth. Move up and down.

  As shown in FIG. 2C, the concave portion 14a may have a tapered shape 14a1 that narrows the facing surface on the opening side from the opening toward the back to facilitate the passage of the elevating cord 15. When the concave portion 14a having the tapered shape 14a1 is formed at both ends of the slat 14, as shown in FIG. 2D, when the slat 14 is tilted (rotated) in the vertical state, the tapered shape 14a1 of the concave portion 14a is formed. As a result, the lifting / lowering cord 15 reaches the recess 14a and a part thereof moves outward. Even when the lifting / lowering cord 15 moves in this manner, the lifting / lowering cord 15 is located at the end of the slat 14, so that the slat 14 does not slip laterally.

<Effects of First Embodiment>
The horizontal blind 10 according to the first embodiment includes a plurality of slats 14 supported by a head box 11 via a ladder cord 12 and a lifting cord 15 that is suspended from the head box 11 and lifts and lowers each slat 14. The configuration is as follows.

  (1) The slat 14 is provided with a recess 14 a at the longitudinal end of the slat 14, and the lifting cord 15 is suspended from the end of the head box 11 through the recess 14 a.

  According to this configuration, the insertion hole for the lifting / lowering cord as in the prior art is not opened in the slat 14. For this reason, when the light from a window etc. is shielded by making the slat 14 into a fully closed state by tilting, it is possible to suppress a problem that conventional light leaks into the room through the insertion hole. That is, light leakage can be suppressed when light is blocked by the slats 14.

  According to this configuration, the lifting / lowering cord 15 passes through the recesses 14 a provided at both ends of the slat 14, and the lifting / lowering cord 15 is provided by being pulled by the bottom rail 13. For this reason, even if the slat 14 tries to move in the longitudinal direction, the end portion of the slat 14 abuts on the lifting / lowering cord 15, so that the movement is suppressed. Further, since the lifting / lowering cord 15 passes through the recess 14a, the lifting / lowering cord 15 is prevented from being displaced from the end portion of the slat 14. Moreover, since the recessed part 14a is provided in the edge part of the slat 14, compared with providing the penetration hole near the center of the longitudinal direction of the slat 14, the influence of light leakage can be suppressed.

<Slat modification 1>
FIG. 5A is a plan view showing the configuration of the end portion of the slat 14 according to the slat modification 1. FIG. In addition, the top view has shown the structure of the one end part among the both ends of the same structure of the slat 14. FIG.

  In the slat modification 1, the end portion of the slat 14 is provided with a recess 14b having an opening width that is significantly larger than the diameter of the elevating cord 15. The opening width corresponds to the front-rear width of the slat 14 and is preferably a dimension several times larger than the diameter of the lifting / lowering cord 15.

  Since the opening width of the recess 14b is significantly larger than the diameter of the lifting / lowering cord 15, the lifting / lowering cord 15 can be easily passed through the recesses 14b at both ends of the slats 14 in a plurality of stages.

  Further, when the slat 14 is erected, if the opening width of the recess 14b is several times the diameter of the lifting / lowering cord 15, the slat 14 stands substantially straight in the vertical direction with the lifting / lowering cord 15 hanging down substantially straight. . For this reason, there is no gap between the slats because the slats standing in the vertical direction are not pushed and bent in the crank shape by the front and rear elevating cords above and below the insertion hole as in the prior art. Therefore, light leakage can be suppressed.

<Slat modification 2>
FIG. 5B is a plan view showing the configuration of the end portion of the slat 14 according to the slat modification 2. FIG.

  In the slat modification 2, arc-shaped portions 14c are provided at both ends of the slat 14 as concave portions obtained by cutting the ends of the slats 14 into an arc shape. The lifting / lowering cord 15 passes in the vertical direction at the most depressed position of the arc-shaped portion 14c. The lifting / lowering cord 15 can be easily passed through the portion of the arc-shaped portion 14c curved in the arc shape.

  Further, when the slat 14 is erected, the arc-shaped portion 14c is curved in an arc shape, so that the slat 14 stands substantially straight in the vertical direction with the lifting cord 15 hanging down substantially straight. For this reason, since the slat 14 does not bend in a crank shape as described in the above-described slat modification 1, a gap is not formed between the slats, and light leakage can be suppressed. The arcuate portion 14c constitutes the curved shape of the present invention.

<Slat modification 3>
FIG. 5C is a plan view showing the configuration of the end portion of the slat 14 according to the slat modification 3. FIG.

  In the slat modification 3, the both ends of the slat 14 are provided with a dogleg-shaped portion 14d as a concave portion obtained by cutting the end of the slat 14 into a dogleg shape. The lifting / lowering cord 15 passes in the up and down direction at the most depressed position of the doglegged portion 14d. The elevating cord 15 can be easily passed through the bent portion of the dog-shaped portion 14d.

  Further, when the slat 14 is erected, the U-shaped portion 14d is only recessed into a U-shape, so that the slat 14 stands substantially straight in the vertical direction with the lifting cord 15 hanging down substantially straight. For this reason, since the slat 14 does not bend in a crank shape as described in the above-described slat modification 1, a gap is not formed between the slats, and light leakage can be suppressed. In addition, 14-shaped part 14d comprises the curved shape of this invention.

<Slat modification 4>
FIG. 6 shows a state in which the slat pressing plate 23 is attached to both ends of the slat 14 according to the slat modification 4, wherein (a) is a perspective view showing the slat pressing plate 23, and (b) is an attachment of the slat pressing plate 23 to the slat 14. The perspective view which shows a state, (c) is a perspective view which shows the aspect which attached the slat pressing plate 23 to the slat 14. FIG.

  A slat presser plate 23 as a holding member shown in FIG. 6 (a) has claw portions 23b disposed so as to be opposed to the front and rear ends of the slat 14 as shown in FIG. 6 (b). It has an insertion hole 23a penetrating in the center of a connection portion (main body portion) 23c that connects the upper and lower sides having the portion 23b. The insertion hole 23 a has a diameter slightly larger than the diameter of the lifting / lowering cord 15.

  As shown in FIG. 6 (b), the slat pressing plate 23 is disposed at a position below the recess 14a {FIG. 2 (b)} of the slat 14, and the lifting / lowering cord 15 passing through the recess 14a is inserted into the insertion hole 23a. . Then, as shown in FIG. 6C, the insertion hole 23a is aligned with the recess 14a, and the slat holding plate 23 is engaged with the end portion of the slat 14 by the claw portion 23b and assembled.

  When the slat pressing plate 23 is assembled to both ends of the slat 14 in this way, the strength of the end of the slat 14 is increased, and bending or the like can be prevented. Further, since the lifting / lowering cord 15 passes through the insertion hole 23a, the lifting / lowering cord 15 is not detached. The slat pressing plate 23 constitutes a plate-like member of the present invention.

  Further, the slat pressing plate 23 is formed by any one of the concave portion 14b shown in FIG. 5 (a), the arc-shaped portion 14c shown in FIG. 5 (b), and the dog-shaped portion 14d shown in FIG. 5 (c). You may combine with the both ends of the slat 14 made.

  In addition, as shown in FIG. 6D, as another slat pressing plate 23, there is no insertion hole 23a in the connection portion (main body portion) 23c, the width of the slat 14 in the longitudinal direction of the connection portion 23c is narrow, and the recess 23e may have a deep shape in the longitudinal direction. At this time, it is assumed that the slat 14 is formed with an elongated recess 14b having an opening width that is significantly larger than the diameter of the elevating cord 15 shown in FIG.

  In the case of this configuration, as shown in FIG. 6 (e), when the slat pressing plate 23 is assembled to both ends of the slat 14, the elongated concave portion 14 b of the slat 14 overlaps with the position of the concave portion 23 e of the slat pressing plate 23. An elongate gap is formed in the front-rear direction, and the elevating cord 15 is inserted into the elongate gap so as to be movable up and down.

  In this case, since the lifting / lowering cord 15 passes through a long and narrow gap, the lifting / lowering cord 15 does not come off. Further, since the elevating cord 15 is inserted into the elongated gap when the slat 14 is tilted (rotated), the movement of the slat 14 is not easily disturbed, and the tilt can be easily performed.

  Instead of the elongated recess 14b of the slat 14, the arc-shaped portion 14c shown in FIG. 5B, the dog-shaped portion 14d shown in FIG. 5C, and the recess 14a shown in FIG. Any one of the concave portions 14b having a tapered shape shown in FIG. 2 (b) may be formed and combined with the slat pressing plate 23 as shown in FIG. 6 (e).

  As shown in FIG. 7 (a), the bottom rail 13 has a rectangular tube shape having a cavity 13c therein, and caps 13p1 are attached to both ends thereof. The cap 13p1 has a curved portion 13e that is curved downward. The curved portion 13e has a size that allows a gap 13f to be formed between the bottom surfaces of the bottom rail 13 at both ends.

  The lower end side of the lifting / lowering cord 15 passes through the recess 13b of the bottom rail 13 along the curved portion 13a, enters the cavity 13c from the gap 13f, is inserted through the through hole 13d from the cavity 13c, and protrudes to the outside. . The protruding tip of the lifting / lowering cord 15 is tied to a round knot 15a larger than the through hole 13d and fixed so as not to come out of the through hole 13d.

  In such a lifting / lowering cord fixing structure, since the tip of the lifting / lowering cord 15 is tied and fixed outside the bottom rail 13, the lifting / lowering cord 15 can be easily fixed.

<Modification 2 of lifting cord fixing structure>
FIG. 7B is a cross-sectional view showing the lifting / lowering cord fixing structure at the end of the bottom rail 13 according to the second modification of the lifting / lowering cord fixing structure. In addition, the same code | symbol is attached | subjected to the part corresponding to Fig.7 (a).

  The lift cord fixing structure modification 2 shown in FIG. 7B is different from the modification 1 in that a through hole 13g is formed on the upper surface of the cavity 13c on the curved portion 13e side. Here, the tip side of the lifting / lowering cord 15 is inserted through the through hole 13g from the cavity 13c and protrudes to the outside. The protruding tip portion is tied to a round knot 15a that is larger than the through hole 13g, and is fixed so as not to come out of the through hole 13d. Also in such a lifting / lowering cord fixing structure, since the tip of the lifting / lowering cord 15 is tied and fixed outside the bottom rail 13, the lifting / lowering cord 15 can be easily fixed.

  In addition, the lifting / lowering cord fixing structure shown in FIG. 4 and the lifting / lowering cord fixing structures of Modifications 1 and 2 shown in FIGS. 7A and 7B realize the structure of the cap 13p and the cap 13p1 with the bottom rail 13. May be. Other than this, any structure may be used as long as the lower end side of the lifting / lowering cord 15 is fixed to the bottom rail 13.
