  Hereinafter, embodiments of the present invention will be described. Various characteristic items shown in the following embodiments can be combined with each other. The invention is established independently for each feature. In the following embodiment, a horizontal blind will be described as an example of the solar shading device, but the present invention mainly has a feature in a method of hanging an elevating cord from a head box. Similarly, the present invention can be similarly applied to a hoisting curtain or a pleated screen in which a solar shading material is moved up and down using an elevating cord.

  In the first to third embodiments described below, the main problem is to share the support member, and in the fourth to fifth embodiments, the main problem is to reduce the size of the head box.

1. First Embodiment FIGS. 1 to 3 show a horizontal blind according to a first embodiment of the present invention. In the horizontal blind shown in FIG. 1, a plurality of ladder cords 2 are suspended from the head box 1, and a bottom rail 4 is attached to the lower end of the ladder cord 2. The ladder cord 2 supports a multi-stage slat 3. The head box 1 is fixed to the window frame and the inner wall by being attached to the bracket 12.

  An upper end portion of the ladder cord 2 is attached to a tilt device 11 disposed in the head box 1. The tilt device 11 rotates the slats 3 in the same phase via the ladder cord 2 based on the rotation of the drive shaft 8 disposed in the head box 1 and rotates until the slats 3 are substantially in the vertical direction. After being moved, each slat 3 is configured not to rotate further in the same direction.

  As shown in FIGS. 2 and 3, a room inner side elevating cord 5 a is suspended inside the slat 3 and a room outer side elevating cord 5 b is suspended outside the slat 3. The lower ends of the elevating cords 5a and 5b are attached to the bottom rail 4. As shown in FIG. 1, the lifting / lowering cords 5 a and 5 b are wound and rewound by a winding shaft 13 that is rotatably supported by a support member 21, whereby the bottom rail 4 is lifted and lowered. .

  A pulley case 10 that rotatably supports an operation pulley (not shown) is provided at the right end of the head box 1, and an endless operation cord 6 is hung on the operation pulley. By operating the operation cord 6, the winding shaft 13 and the tilt device 11 are rotated through the drive shaft 8, so that the lifting operation of the bottom rail 4 and the angle adjustment operation of the slat 3 can be performed.

  As shown in FIG. 3 (a), a guide member support 9a for supporting the external guide member 7a is attached to the lower surface inside the room of the support member 21, and as shown in FIG. 3 (b), the external guide member A guide member support 9b that supports 7b is attached to the lower surface of the support member 21 on the outside of the room. The guide member support 9a supports the external guide member 7a so that the external guide member 7a protrudes downward inside the room of the head box 1, and the guide member support 9b includes the external guide member 7b outside the room of the head box 1. The external guide member 7b is supported so as to protrude downward from the bottom. As shown in FIGS. 3A to 3B, the support member 21 is a member that can be used even with a horizontal blind that hangs an elevating cord from substantially the center in the front-rear direction of the solar radiation shielding device as shown in Patent Document 1. For this purpose, a central guide member 7e is provided at the lower portion of the support member 21 at the substantially center in the front-rear direction.

  The configuration of the guide member support 9a is not particularly limited. For example, as illustrated in FIG. 3C, the guide member support 9a includes a main body 9a1 and a pair of side walls 9a2 extending substantially vertically from both sides of the main body 9a1. It is. Further, the configuration of the guide member 7a is not particularly limited, and in one example, as shown in FIG. 3C, a pulley shaft 7b1 supported by the side wall portion 9a2 and a pulley rotatably supported by the pulley shaft 7b1. 7b2. In this embodiment, the guide member support 9a is attached to the lower surface of the support member 21, but may be attached to the head box 1. Moreover, the attachment method of the guide member support body 9a is not specifically limited, It can attach by methods, such as a snap mechanism, adhesion | attachment, and welding. The description about the structure and attachment method of the guide member support 9b and the guide member 7b is the same as that of the guide member support 9a and the guide member 7a.

  As shown in FIG. 3A, the room inner lifting / lowering cord 5a is guided into the head box 1 through the room inner side of the outer guide member 7a inside the room and through the room outer side of the central guide member 7e. As shown in FIG. 3B, the outdoor lifting code 5b passes through the outside of the external guide member 7b outside the room and is guided into the head box 1 through the inside of the central guide member 7e. As described above, in this embodiment, the room inner lifting / lowering cord 5a is guided from the outside of the head box 1 into the head box 1, and the room outer lifting / lowering cord 5b is guided from the inner side of the head box 1 into the head box 1. Is characteristic.

  In the present embodiment, the lifting / lowering cords 5a and 5b are wound up by rotating the drive shaft 8 in the counterclockwise direction (arrow X direction) in FIGS. 5a and 5b are guided to the outside of the room of the winding shaft 13, but the winding direction of the elevating cords 5a and 5b may be the clockwise direction in FIGS. In that case, the lifting / lowering cords 5 a and 5 b are guided inside the room of the winding shaft 13.

  Further, in this embodiment, the room inside lifting / lowering cord 5a is guided into the head box 1 from the outside of the room, and the room outside lifting / lowering cord 5b is guided into the head box 1 from the inside of the room. About any one of them, the center guide member 7e may not be used. For example, the outside door opening / closing cord 5b may be guided directly into the head box 1 through the outside of the outside guide member 7b outside the room, or may be guided into the head box 1 without using the outside guide member 7b. May be. The same applies to the room inside lifting / lowering cord 5a.

  Thus, according to this embodiment, by attaching the guide member supports 9a and 9b so as to protrude below the outside of the room of the head box 1, the same support member 21 as that of the conventional product is used to It becomes possible to wind up around the winding shaft 13 of the lifting / lowering cords 5a and 5b suspended along the side surface in the front-rear direction. As a result, the support member 21 and the head box 1 that supports the support member 21 can be used in common with the conventional product, and the effort for newly designing the support member 21 can be saved.

This embodiment can also be implemented in the following aspects.
The above embodiment has been described by taking a horizontal blind as an example, but instead of a slat, a screen for a pleat screen or a curtain fabric for a curtain for lifting is supported by being suspended from a head box. It can also be moved up and down using a lifting cord suspended in the same manner.

2. Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIG. In the present embodiment, as shown in FIG. 4, the winding direction of the lifting / lowering cords 5a and 5b is opposite to the first embodiment (the direction of the arrow Y in FIGS. 4A to 4B), The difference between the mounting positions of the guide member supports 9a and 9b from the first embodiment is the main difference from the first embodiment. Hereinafter, a description will be given focusing on differences from the first embodiment. In the present embodiment, the support member 21 that does not have the central guide member 7e is used, but the support member 21 that has the central guide member 7e may be used as in the first embodiment.

  In this embodiment, as shown to Fig.4 (a), a guide member support body is attached to the support member 21 which rotatably supports the winding shaft 13 which winds and unwinds the room inner side raising / lowering cord 5a. However, as shown in FIG. 4B, the external guide member 7a is provided on the lower surface of the support member 21 that rotatably supports the winding shaft 13 for winding and unwinding the outdoor lifting / lowering cord 5b. A guide member support 9a for supporting the external guide member 7b is attached to the lower surface of the same support member 21 on the outside of the room. The structure of the guide member supports 9a and 9b and the external guide members 7a and 7b, the description of the attachment method, and the like are the same as in the first embodiment.

  As shown in FIG. 4 (a), the room inner lifting / lowering cord 5a is guided into the head box 1 from the room inner side of the head box 1 without an external guide member. On the other hand, as shown in FIG. 4 (b), the room outside lifting / lowering cord 5b passes through the room outside of the guide member 7b outside the room, passes through the room inside of the guide member 7a inside the room, and goes inside the room inside the head box 1. To the head box 1.

  Thus, in this embodiment, since both the raising / lowering cords 5a and 5b are guided into the head box 1 from the inside of the head box 1, the handling of the raising / lowering cords 5a and 5b in the head box 1 is performed. There is an advantage that it can be the same.

  In the above description, the inside of the room and the outside of the room can be reversed. That is, the room outside lifting / lowering cord 5b is guided into the head box 1 from the outside of the head box 1 without passing through the external guide member, and the room inside lifting / lowering cord 5a passes through the inside of the room inside the room inside guide member 7a. The guide member 7b may be guided from the outside of the head box 1 into the head box 1 through the outside of the room.

3. Third Embodiment Next, a third embodiment of the present invention will be described with reference to FIG. Although this embodiment is similar to the second embodiment, as shown in FIG. 5, the handling of the outdoor lifting / lowering cord 5b is mainly different from that of the second embodiment, so this point will be mainly described.

  In this embodiment, as shown to Fig.5 (a), a guide member support body is attached to the support member 21 which rotatably supports the winding shaft 13 which winds and unwinds the room inner side raising / lowering cord 5a. As shown in FIG. 5B, the outdoor lifting / lowering cord 5b is attached to the lower surface of the support member 21 that rotatably supports the winding shaft 13 for winding and unwinding the outdoor lifting / lowering cord 5b. A lower guide member support 9c for supporting the outer guide members 7c1 and 7c2 for guiding the rear of the box 1 is attached, and the outdoor lifting / lowering cord 5b is placed above the guide member support 9c in the longitudinal direction of the head box 1. An upper guide member support 9 d that supports the external guide members 7 d 1 and 7 d 2 that are guided to the center side of the support member 21 is attached to the upper surface of the support member 21.

  The description of the structure and attachment method of the guide member supports 9c, 9d and the external guide members 7c1, 7c2, 7d1, 7d2 is the same as that of the first embodiment.

  As shown in FIG. 5A, the room inner lifting / lowering cord 5a is guided into the head box 1 from the room inner side of the head box 1 without an external guide member. On the other hand, as shown in FIG. 5B, the outdoor lifting / lowering cord 5b is guided to the rear of the head box 1 by the lower external guide members 7c1 and 7c2, and then the head box 1 by the upper external guide members 7d1 and 7d2. Are guided to the center side in the front-rear direction, and are guided into the head box 1 from the upper side of the head box 1. More specifically, the outdoor lifting / lowering cord 5b passes through the inside of the lower external guide member 7c1 provided outside the room at a position protruding below the head box 1, and protrudes toward the outside of the head box 1 in the room direction. The lower external guide member 7c2 provided at the lower portion of the head box 1 passes through the outside of the room and passes through the outside of the upper external guide member 7d1 provided at the upper portion of the head box 1 in the direction of the outside of the room. It is guided into the head box 1 through the inside of the upper external guide member 7d2 provided outside the room at the protruding position.

  The arrangement of the external guide members 7c1, 7c2, 7d1, and 7d2 shown in FIG. 5B is an example, and a position where the outdoor lifting / lowering cord 5b protrudes toward the outside of the head box 1 on the lower side of the head box 1. In other words, another arrangement may be employed as long as the outdoor lifting / lowering cord 5b can be guided to the center side in the front-rear direction of the head box 1 on the upper side of the head box 1. Further, the number of the guide members 7c1, 7c2, 7d1, 7d2 is not necessarily two, and may be one or three or more, for guiding the outdoor lifting / lowering cord 5b as described above. What is necessary is just to arrange | position a required number.

  In the above description, the inside of the room and the outside of the room can be reversed. That is, the outdoor lifting / lowering cord 5b is guided into the head box 1 from the outside of the head box 1 without passing through the external guide member, and the indoor lifting / lowering cord 5a is guided to a position protruding from the head box 1 toward the inner side of the room. The head box 1 may be guided from the upper side of the head box 1.

  Since the lower guide member support 9c is provided on the lower side of the head box 1, the lower guide member support 9c is easily noticed by the user, but the upper guide member support 9d is provided on the upper side of the head box 1. , Hard to catch the eyes of the user. Therefore, according to the present embodiment, compared to the first and second embodiments, the number of guide member supports arranged at positions that can be easily perceived by the user can be reduced, and the aesthetic appearance is improved.

4). Fourth Embodiment A fourth embodiment of the present invention will be described with reference to FIGS. The first to third embodiments relate to a winding-type solar shading device that lifts and lowers the solar shading material by winding and unwinding the lifting / lowering cord using a winding shaft. The embodiment relates to a direct-drawing type solar shading device that lifts and lowers the solar shading material by pulling up the lifting / lowering cord guided in the head box from another position of the head box and changing the pulling amount. However, this embodiment is also applicable to a wind-up type solar radiation shielding device.
Hereinafter, a horizontal blind will be described as an example of the solar shading device.

  In the horizontal blind shown in FIG. 6, a plurality of ladder cords 2 are suspended from the head box 1, and a bottom rail 4 is attached to the lower end of the ladder cord 2. The ladder cord 2 supports a multi-stage slat 3. The head box 1 is fixed to the window frame and the inner wall by being attached to the bracket 12.

  An upper end portion of the ladder cord 2 is attached to a tilt device 11 disposed in the head box 1. The tilt device 11 rotates the slats 3 in the same phase via the ladder cord 2 based on the rotation of the drive shaft 8 disposed in the head box 1 and rotates until the slats 3 are substantially in the vertical direction. After being moved, each slat 3 is configured not to rotate further in the same direction.

  As shown in FIGS. 6 to 7, a room inner side elevating cord 5 a is suspended inside the room of the slat 3, and a room outer side elevating cord 5 b is suspended outside the room of the slat 3. The lower ends of the elevating cords 5a and 5b are attached to the bottom rail 4. The elevator cords 5a and 5b are guided into the head box 1 and then pulled out from the cord outlet 6c at the right end of the head box 1 and attached to the equalizer 6a. By pulling the equalizer 6a, the length by which the elevating cords 5a and 5b are pulled out from the cord outlet 6c is increased, and the bottom rail 4 is raised. When the force applied to the equalizer 6a is loosened in this state, the stopper 23 is activated to hold the lifting cords 5a and 5b, and the lowering of the bottom rail 4 due to its own weight is prevented. When the equalizer 6a is pulled a little again, the stopper 23 releases the elevating cords 5a and 5b, and the bottom rail 4 can be lowered. When the operation pole 6b is rotated, the rotation is transmitted to the tilt device 11 through the drive shaft 8, and the slat 3 is rotated.

  The outdoor lifting / lowering cord 5b is guided into the head box 1 from below the head box 1 by a guide member provided in the head box 1 as in the conventional technique. For example, the guide member includes a pulley and a pulley shaft that rotatably supports the pulley, as in the first embodiment. The method for supporting the pulley shaft is not limited, and the tilt device 11 may support the pulley shaft, or a support member for supporting the pulley shaft may be separately provided.

  The present embodiment is particularly characteristic in that the room inner lifting / lowering cord 5a is guided into the head box 1. As shown in FIG. 8, the room inside lifting / lowering cord 5 a is guided into the head box 1 by the external guide member 14 d, but the external guide member 14 d is disposed so as to protrude outward in the front-rear direction from the front wall of the head box 1. Has been. Conventionally, it has been common knowledge that the guide member that guides the lifting / lowering cord into the head box is arranged so as not to protrude from the head box 1, so that the external guide member 14 d is placed outside the head box 1 in the front-rear direction. Protruding and disposing is far from conventional common sense.

  The external guide member 14 d is supported by the guide member support 14. As shown in FIG. 8B, the guide member support 14 includes a guide member support portion 14b that supports the external guide member 14d, and an oblique direction from the external guide member 14d toward the center in the front-rear direction of the head box 1. An inclined portion 14a extending in the direction is provided. As shown in FIG. 9C, the external guide member 14d is a pulley that is rotatably supported by a pulley shaft 14i in this embodiment.

  As shown in FIG. 8B, a guide groove 14c is provided in the vicinity of the external guide member 14d along the inclined portion 14a to accommodate the lifting / lowering cord 5a. As shown in FIG. 8 (a), the lifting / lowering cord 5a is guided into the guide groove 14c by the external guide member 14d from below the position of the head box 1 protruding in the room inner direction, and along the inclined portion 14a. The head box 1 is guided to the center in the front-rear direction. The inclined portion 14a is protected by, for example, a metal protection plate 14f in order to suppress wear due to friction with the elevating cord 5a.

  Next, a method for attaching the guide member support 14 to the head box 1 will be described. First, as shown in FIGS. 9B and 9C, the guide member support portion 14 b is inserted into the opening 1 a formed in the front wall of the head box 1 from the inner side in the front-rear direction of the head box 1. The opening 1a has substantially the same shape as the outer shape of the guide member support 14b in the front view shown in FIG. As shown in FIGS. 8B and 9B, engaging grooves 14g are formed on both sides of the guide member support portion 14b in the width direction, and protrusions 14h are provided in the engaging grooves 14g. ing. As shown in FIG. 9B, tapered surfaces 14j are provided on both side surfaces of the protrusion 14h in the direction in which the engaging groove 14g extends.

  As shown in FIG. 11, the holding cover 15 engaged with the guide member support 14 has side wall portions 15b extending substantially vertically from both sides in the width direction of the main body portion 15a, and inward in the width direction from the side wall portions 15b on both sides. A protruding upper engaging convex portion 15c1 and a lower engaging convex portion 15c2 are provided. An inclined wall 15d is provided above the main body 15a.

  To engage the holding cover 15 with the guide member support 14, as shown in FIG. 8 (b), the guide member support portion 14b protrudes toward the inside of the room of the head box 1, and in this state, FIG. 9 (b). As shown in FIG. 4, the holding cover 15 is moved from the upper side of the guide member supporting portion 14b so that the lower engaging convex portion 15c2 of the holding cover 15 enters the engaging groove 14g along the outer surface of the front wall of the head box 1. Move the slide. When the holding cover 15 is further pushed down in a state where the lower engagement convex portion 15c2 is in contact with the tapered surface 14j of the protrusion 14h, the lower engagement convex portion 15c2 gets over the protrusion 14h along the tapered surface 14j, and the protrusion 14h. Is disposed between the upper engaging convex portion 15c1 and the lower engaging convex portion 15c2, so that the holding cover 15 is engaged with the guide member support body 14. When removing the holding cover 15, if a strong upward force is applied to the holding cover 15, the lower engagement convex portion 15 c 2 gets over the protrusion 14 h, so that the holding cover 15 is removed from the guide member support 14. Can be removed. In addition, the surface which contact | abuts the taper surface 14j of the upper side engagement convex part 15c1 and the lower side engagement convex part 15c2 is rounded.

  In this state, as shown in FIG. 8A, the guide member support 14 contacts the inner surface of the front wall of the head box 1 at three contact portions 14 e, and the side wall portions 15 b on both sides of the holding cover 15 Since the tip 15e contacts the outside of the front wall of the head box 1, the holding cover 15 and the guide member support 14 cannot be moved in the front-rear direction and are attached to the head box 1.

  With the above configuration, the external guide member 14 d can be disposed so as to protrude outward in the front-rear direction of the head box 1. In the prior art, when the lifting / lowering cord is suspended along the front / rear side of the solar shading material, it is necessary to extend the head box to the hanging position of the lifting / lowering cord, and the head box becomes longer in the front / rear direction accordingly. There was a problem. On the other hand, according to the present embodiment, the length of the head box 1 in the front-rear direction is conventionally increased by guiding the lifting / lowering cord into the head box 1 by the external guide member 14d disposed so as to protrude outward in the front-rear direction of the head box 1. Therefore, in this embodiment, the length of the head box 1 in the front-rear direction is shorter than the length of the slat 3 in the front-rear direction, as shown in FIG. 6B. It has become.
