BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiments do not limit the present invention.
[0013]
FIG. 1 is a front view showing an embodiment in which the blind operating device of the present invention is applied to a horizontal blind as a blind. In the drawing, a blind 10 has a head box 12 attached to a fixed portion such as a wall surface or a ceiling surface via a bracket, and the head box 12 has a plurality of ladder-like ladder cords hanging from the head box 12. The multi-stage slats 18 constituting the shielding material are supported in an aligned state by the slats 16. One end of the ladder cord 16 is connected to a bottom rail 19 disposed below the lowermost slat 18.
[0014]
The operating device for a blind according to the present invention includes a plurality of elevating cords 14 as a plurality of operating cords hanging from the head box 12. One end of each lifting cord 14 is connected to a bottom rail 19, and the other end is inserted into the lifting cord insertion hole of each slat 18, introduced into the head box 12, and then arranged along the longitudinal direction of the head box 12. Then, the head box 12 is led out from an opening 12 a provided at one end of the head box 12 through a stopper (not shown). The slat 18 is moved up and down by manipulating the end of the lifting cord 14 hanging from the opening 12a of the head box 12.
[0015]
A bag-shaped member 22 is suspended from around the opening 12 a of the head box 12. The bag-like member 22 can be made of a soft plastic, a woven fabric, a knitted fabric, a non-woven fabric, or the like, and is preferably light and flexible. The outer peripheral surface of the bag-shaped member 22 is preferably transparent or opaque and is provided with a pattern or the like, and the design is considered. In the bag-like member 22, the vicinity of the end of the lifting cord 14 suspended from the head box 12 can be stored. That is, the plurality of lifting / lowering cords 14 are led out of the opening 12a of the head box 12, and then connected to each other by the connecting tool 20 to form an extension 14a. A part of the extension 14a is attached to the bag-like member 22. It can be stored. The end of the extension 14a is connected to the bag-like member 22 inside or outside the cylinder. The extension 14a after being connected by the connecting tool 20 may be integrated with the lifting cord 14, but may be separate or have no extension 14a at all. The plurality of lifting cords 14 may be housed in the bag-like member 22 as they are, and their ends may be connected to the bag-like member 22. When the extension cord 14 is provided, the elevating cord 14 including the extension cord 14a forms an operation code.
[0016]
In the blind operating device configured as described above, when raising and lowering the slat 18, the extension 14 a of the lifting cord 14 stored in the bag-like member 22 is taken out. At this time, it is not necessary to take out the entire extension 14 a of the lifting cord 14 from the bag-like member 22. After the lifting cord 14 is removed from the bag-like member 22 by an appropriate length for the operation, the removed portion is slightly pulled downward to release the stopper. When the stopper is released, the lifting cord 14 can be freely moved. In this state, when the portion of the lift cord 14 taken out is further pulled downward, the bottom rail 19 rises and rises sequentially from the lower slat 18. Conversely, when the removed portion is moved upward according to the weight of the bottom rail 19 and the slat 18, the slat 18 is lowered. After the operation is completed, the stopper is fastened to prohibit the movement of the elevating cord 14, and then the removed portion of the elevating cord 14 is stored in the bag-shaped member 22 again.
[0017]
Thereby, when not in use, the plurality of lifting / lowering cords 14 are not separated, but are suspended from the headbox 12 as a bag-shaped member 22 as a whole, so that in effect, one cord is suspended. Thus, it is possible to prevent an object or a person from being caught on the elevating cord 14.

[0023]
Preferably, a pulley 50 around which the lower end of the endless operation cord 46 is wound is arranged in the bag-shaped member 48. The pulley 50 itself serves as a weight, but when the weight of the pulley 50 alone is insufficient, the pulley 50 may be separately provided with a weight 50a. Will be added. Since the pulley 50 does not need to be engaged with the operation cord 46 formed of a ball chain, the surface around which the operation cord 46 is wound may have a shape without irregularities so that the operation cord 46 can slide smoothly.
[0024]
In the blind operating device configured as described above, when the screen 38 is to be moved up and down, the operation code 46 is operated from the opening 48 a in the state of the operation code 46 stored in the bag-like member 48. When one side of the endless operation cord 46 is pulled downward, the pulley in the operation part 42 rotates accordingly, the winding pipe 36 rotates in the same direction, and the screen 38 turns the winding pipe. The screen 38 is unwound or wound up to raise or lower the screen 38. When the other side of the operation cord 46 is pulled downward, the winding pipe 36 rotates in a direction opposite to the previous direction, and the screen 38 is lowered or raised.
[0025]
As described above, since the endless operation code 46 is always stored in the bag-like member 48 and is suspended from the operation unit 42 as a bag-like member 48, one operation code is practically suspended. As a result, it is possible to prevent an object or a person from being caught on the endless operation code 46. Further, since the operation code 46 is tensioned by the pulley 50, the operation code 46 can be easily operated even in the bag-shaped member 48 without pulling out the operation code 46 from the bag-shaped member 48. Can be. However, optionally, similarly to the first embodiment, when the endless operation code 46 is used, the operation code 46 is taken out of the bag-like member 48, and after use, it may be stored in the bag-like member 48 again. it can. In this case, the pulley 50 can be omitted.
[0026]
As described above, according to each embodiment, it is possible to prevent a person or an object from being caught on the operation code. The bag-shaped member can be manufactured in common regardless of the number of operation codes and the like, and can be applied to all sizes and types of blinds. That is, the blind is not limited to the blind described in the above embodiment, and a bag-shaped member common to any blind operating device such as a Roman shade, a pleated screen, and a vertical blind may be used. For this reason, manufacturing costs and component management costs can be reduced.
