Japanese Unexamined Patent Publication No. 2016-333323

In the horizontal blind of Patent Document 1 described above, the elevating cord is passed through the insertion hole of the slats and hung down. In addition, a dummy cord is passed through the insertion hole of the slat and hung down to prevent lateral displacement of the slat. For this reason, when the light from the window is blocked by tilting the slat to make it fully closed, there is a problem that the light leaks into the room through the insertion hole.

The present invention has been made in view of such a background, and an object of the present invention is to provide a horizontal blind capable of suppressing light leakage when light is shielded by slats.

In order to solve the above problems, the horizontal blind of the present invention is a horizontal type having a plurality of stages of slats supported by a ladder cord in the head box and an elevating cord suspended from the head box to raise and lower each slat. A blind, the slat having a recess at the longitudinal end of the slat, the elevating cord hanging from the longitudinal end of the headbox through the recess and of the slat. A holding member attached to an end portion in the longitudinal direction and holding the elevating cord is provided, and the holding member includes a main body portion extending in the lateral direction of the slats and the lateral end of the main body portion. A claw portion provided in the portion and an insertion hole formed through the main body portion are provided, the insertion hole is arranged in the recess, and the holding member is assembled to the slats by the claw portion, and the insertion hole is provided. It is characterized in that the elevating cord is inserted into the recess.

According to this configuration, since the recess is provided at the end of the slat, the influence of light leakage can be suppressed as compared with the case where the insertion hole is provided near the center in the longitudinal direction of the slat. Further, the elevating cord passes through the recesses provided on both end sides of the slats, and the elevating cord is provided by being pulled by the bottom rail. Therefore, even if the slat tries to move in the longitudinal direction, the end of the slat comes into contact with the elevating cord, so that the movement is suppressed. Further, since the elevating cord passes through the recess, the elevating cord is prevented from being displaced from the end of the slat.

According to this configuration, the elevating cord can be easily passed through the recess. Further, when the plate-shaped members are attached to both ends of the slats, the strength of the ends of the slats is increased, and bending and the like can be prevented. Further, since the elevating cord passes through the insertion hole, the elevating cord will not come off.

Further, the recess is characterized in that the opening width of the entrance portion to be opened is made larger than the diameter of the elevating cord.

According to this configuration, if the opening width of the recess is made significantly larger than the diameter of the cord or the elevating cord by several times or more, the cord or the elevating cord can be easily passed through the recesses at both ends of each slat. Further, when the slats are erected, the opening width of the recess is significantly larger than the diameter of the elevating cord, so that the slats stand substantially straight in the vertical direction with the elevating cord hanging substantially straight. For this reason, the slats standing in the vertical direction are not pushed to the opposite sides by the front and rear elevating cords and bent in a crank shape at the top and bottom of the insertion hole as in the conventional case, so that there is no gap between the slats. Therefore, light leakage can be suppressed.

Further, the recess is characterized in that both ends of the slats in the longitudinal direction are curved in an arc shape.

Further, the recess is characterized in that both ends of the slats in the longitudinal direction are curved in a dogleg shape.

According to these configurations, since the concave portion has an arc shape or a dogleg shape, the cord or the elevating cord can be easily passed through. Further, when the slats are erected, the recesses are arcuate or doglegged, so that the slats stand substantially straight in the vertical direction with the elevating cord hanging substantially straight. For this reason, the slats standing in the vertical direction are not pushed to the opposite sides by the front and rear elevating cords and bent in a crank shape at the top and bottom of the insertion hole as in the conventional case, so that there is no gap between the slats. Therefore, light leakage can be suppressed.

In addition, a horizontal type having a plurality of stages of slats supported by a ladder cord in the head box, an elevating cord suspended from the head box to raise and lower each slat, and a lateral slip prevention cord for preventing lateral slippage of the slats. A blind, the slat having a recess at the longitudinal end of the slat, the recess having a substantially circular hole slightly smaller than the diameter of the strike-prevention cord for preventing strike-slip. It is characterized in that the cords are fitted and inserted without gaps.

According to this configuration, even when the slats are fully closed, light leakage can be suppressed from the recesses of the slats through which the lateral slip prevention cord is inserted.
Further, it is a horizontal blind provided with a plurality of stages of slats supported by a ladder cord in the head box and an elevating cord suspended from the head box to raise and lower each slat, and the slat is the longitudinal length of the slat. The elevating cord is provided with a recess at the end in the direction, and the elevating cord hangs down from the longitudinal end of the headbox through the recess, and the recess has an opposing surface that is continuous with the opening inlet and faces each other. The facing surfaces have a tapered shape in which the distance between them narrows from the entrance to the back, and when the slats are rotated in a vertical state, the elevating cord approaches the recess due to the tapered shape of the recess. It is characterized in that a part is moved to the outside.
According to this configuration, even if the elevating cord moves, the elevating cord is located at the end of the slat, so that the slat cannot be laterally displaced.

In the horizontal blind of the present invention, light leakage can be suppressed when light is blocked by slats.

<Structure of the first embodiment>
The 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 the configuration of a horizontal blind according to the first embodiment of the present invention.

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

In the horizontal blind 10, ladder cords 12 are hung near both sides of the head box 11, and bottom rails 13 are attached to the lower ends of the ladder cords 12. The ladder cord 12 is supported by slats 14 extending in the lateral direction arranged in a plurality of stages in the vertical direction. That is, as shown in FIG. 2A, the ladder code 12 is composed of two warp threads 12 and two weft threads 12a and 12b intersecting between the warp threads 12 and two weft threads 12a. , 12b, the slat 14 is inserted and supported.

Recesses 14a are formed at both ends of the slat 14 in the longitudinal direction. The recess 14a is enlarged and shown in FIG. 2 (b). In the recess 14a, elevating cords 15 hanging from both ends of the head box 11 along both ends of each slat 14 pass up and down. The elevating cord 15 is separated from the slat 14 in the recess 14a when each slat 14 is stationary.

As shown in FIG. 1, the elevating cords 15 on both sides are hung on one side through rollers 16 rotatably attached to both ends of the head box 11. The other side of the elevating cord 15 passing through the roller 16 is inserted into the internal space 11b of the head box 11 shown in FIG. 3 from each of the left and right sides. As shown in FIG. 1, these inserted elevating cords 15 are led out to the outside from an opening 11a provided so as to penetrate the front wall of the head box 11, and the led-out tip side is fixed to the operating portion 17. Has been done. The opening 11a is provided with a stopper function (not shown) for fixing the elevating cord 15 in the middle of the elevating operation. The roller 16 may be fixed rather than rotatable, and may be a member that regulates the elevating cord 15 so as to hang down from both ends of the bottom rail 13.

The lower ends of the elevating cord 15 hanging along both end sides of each slat 14 are fixed to the bottom rail 13. The fixed structure of one end of both ends of the bottom rail 13 is shown in the cross-sectional view of FIG. 4A and the perspective view of FIG. 4B. As shown in FIG. 4, the bottom rail 13 has a square tubular shape having a cavity 13c inside, and caps 13p are attached to both ends thereof. The cap 13p has a curved portion 13a curved downward, and a recess 13b is formed at the upper end portion of the curved portion 13a. Further, a through hole 13d is formed on the bottom surface of the bottom rail 13 in the vicinity of the cap 13p of the cavity 13c.

The lower end side of the elevating cord 15 is inserted into the through hole 13d while passing through the recess 13b of the cap 13p and abutting along the curved portion 13a. The tip of the inserted elevating cord 15 is tied to a round knot 15a larger than the through hole 13d in the cavity 13c and fixed so as not to come out of the through hole 13d.

Further, a tilt pole 18 is vertically attached to the outer surface on the right side of the head box 11 shown in FIG. The upper end side of the tilt pole 18 is connected to the ladder cord 12 via 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 threads 12 of the ladder cord 12 move up and down in opposite directions by the rotation mechanism portion 18b connected by the tilt shaft 18a, and this movement causes the slats 14 to move horizontally. It is designed to rotate toward a state or a state perpendicular to the horizontal. At this time, when the slat 14 is fully rotated toward the vertical state, it is in the fully closed state, and when it is fully rotated toward the horizontal state, it is in the fully open state.

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 the slats 14 and the bottom rail 13 supported by the ladder cord 12 are brought together. To rise. By releasing the operation unit 17 at an arbitrary ascending position, the elevating cord 15 is fixed by the stopper function. After this fixing, if the operation unit 17 is slightly pulled and loosened, the fixing of the elevating cord 15 is released. After this release, when the force for pulling the operation unit 17 downward is released or weakened, the elevating cord 15 extends downward and each slat 14 and the bottom rail 13 descend.

During such ascent and descent, since the elevating cord 15 passes through the recesses 14a on both ends of each slat 14 and is fixed to the bottom rail 13, the slat 14 is suppressed from being displaced in the lateral direction, and the slat 14 is smooth. Move up and down.

As shown in FIG. 2C, the recess 14a may have a tapered shape 14a1 in which the facing surface on the opening side narrows from the opening toward the back in order to facilitate the passage of the elevating cord 15. When the recesses 14a having the tapered shape 14a1 are formed on both end sides of the slat 14, when the slat 14 is tilted (rotated) in the vertical state as shown in FIG. 2D, the tapered shape 14a1 of the recess 14a is formed. The lifting cord 15 approaches the recess 14a and a part of the lifting cord 15 moves outward. Even when the elevating cord 15 moves in this way, the elevating cord 15 is located at the end of the slat 14, so that the slat 14 does not shift laterally.

<Effect of the first embodiment>
The horizontal blind 10 of the first embodiment includes a plurality of stages of slats 14 supported by the head box 11 via a ladder cord 12, and an elevating cord 15 suspended from the head box 11 for raising and lowering each slat 14. It has the following structure.

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

According to this configuration, the slat 14 is not opened with the insertion hole of the elevating cord as in the conventional case. Therefore, when the slats 14 are fully closed by tilting to block the light from the window or the like, it is possible to suppress a problem that the conventional light leaks into the room through the insertion hole. That is, light leakage can be suppressed when the light is blocked by the slats 14.

According to this configuration, the elevating cord 15 passes through the recesses 14a provided on both end sides of the slat 14, and the elevating cord 15 is provided by being pulled by the bottom rail 13. Therefore, even if the slat 14 tries to move in the longitudinal direction, the end portion of the slat 14 comes into contact with the elevating cord 15, so that the movement is suppressed. Further, since the elevating cord 15 passes through the recess 14a, the elevating cord 15 is prevented from being displaced from the end portion of the slat 14. Further, since the recess 14a is provided at the end of the slat 14, the influence of light leakage can be suppressed as compared with the case where the insertion hole is provided near the center in the longitudinal direction of the slat 14.

<Slat deformation example 1>
FIG. 5A is a plan view showing the configuration of the end portion of the slat 14 according to the slat deformation example 1. The plan view shows the configuration of one end of the two ends of the same configuration of the slat 14.

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

Since the opening width of the recess 14b is significantly larger than the diameter of the elevating cord 15, the elevating cord 15 can be easily passed through the recesses 14b at both ends of the multi-stage slat 14.

Further, when the slat 14 is erected, if the opening width of the recess 14b is several times or more the diameter of the elevating cord 15, the slat 14 stands substantially straight in the vertical direction with the elevating cord 15 hanging substantially straight. .. For this reason, the slats standing in the vertical direction are not pushed to the opposite sides by the front and rear elevating cords and bent in a crank shape at the top and bottom of the insertion hole as in the conventional case, so that there is no gap between the slats. Therefore, light leakage can be suppressed.

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

In the slat deformation example 2, arc-shaped portions 14c are provided at both ends of the slat 14 as recesses in which the ends of the slat 14 are cut into an arc shape. The elevating cord 15 passes in the vertical direction at the most recessed position of the arc-shaped portion 14c. The elevating cord 15 can be easily passed through the arc-shaped portion of the arc-shaped portion 14c.

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 elevating cord 15 hanging substantially straight. Therefore, as described in the above-mentioned slat deformation example 1, the slat 14 does not bend like a crank, so that no gap is formed between the slat and light leakage can be suppressed. The arc shape portion 14c constitutes the curved shape of the present invention.

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

In the slat modification example 3, dog-shaped portions 14d as recesses in which the ends of the slats 14 are cut into a dogleg shape are provided at both ends of the slats 14. The elevating cord 15 passes in the vertical direction at the most recessed position of the doglegged portion 14d. The elevating cord 15 can be easily passed through the doglegged portion 14d of the doglegged portion 14d.

Further, when the slats 14 are erected, the dogleg-shaped portion 14d is only recessed in a dogleg shape, so that the slats 14 stand substantially straight in the vertical direction with the elevating cord 15 hanging substantially straight. Therefore, as described in the above-mentioned slat deformation example 1, the slat 14 does not bend like a crank, so that no gap is formed between the slat and light leakage can be suppressed. The dogleg-shaped portion 14d constitutes the curved shape of the present invention.

<Slat deformation example 4>
FIG. 6 shows a mode in which the slat holding plates 23 are attached to both ends of the slat 14 according to the slat deformation example 4, (a) is a perspective view showing the slat holding plate 23, and (b) is the slat holding plate 23 attached to the slat 14. A perspective view showing a state, (c) is a perspective view showing a state in which the slat holding plate 23 is attached to the slat 14.

The slat holding plate 23 as a holding member shown in FIG. 6 (a) has claw portions 23b arranged so as to be assembleable at 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 the connecting portion (main body portion) 23c that connects the upper and lower sides having the portion 23b. The insertion hole 23a has a diameter slightly larger than the diameter of the elevating cord 15.

As shown in FIG. 6B, the slat holding plate 23 is arranged at a position below the recess 14a {FIG. 2B} of the slat 14, and the elevating 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 to be assembled.

When the slat pressing plates 23 are attached to both ends of the slat 14 in this way, the strength of the end portions of the slat 14 is increased, and bending and the like can be prevented. Further, since the elevating cord 15 passes through the insertion hole 23a, the elevating cord 15 will not come off. The slat pressing plate 23 constitutes the plate-shaped member of the present invention.

Further, any of the concave portion 14b shown in FIG. 5A, the arc-shaped portion 14c shown in FIG. 5B, and the dogleg-shaped portion 14d shown in FIG. 5C is formed on the slat pressing plate 23. It may be combined with both ends of the slats 14 formed.

In addition, as shown in FIG. 6D, as another slat holding plate 23, the connecting portion (main body portion) 23c does not have an insertion hole 23a, the width of the slat 14 of the connecting portion 23c in the longitudinal direction is narrow, and a recess is provided. A 23e having a deep shape in the longitudinal direction may be applied. At this time, it is assumed that the slat 14 has an elongated recess 14b having an opening width significantly larger than the diameter of the elevating cord 15 shown in FIG. 5A on the end side of the slat 14.

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

In this case, since the elevating cord 15 passes through the elongated gap, the elevating cord 15 will 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 less likely to be hindered, and the slat 14 can be easily tilted.

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