DETAILED DESCRIPTION OF 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 figure, a blind 10 has a head box 12 attached to a fixed part such as a wall surface or a ceiling surface via a bracket. The head box 12 includes a plurality of ladder-like ladder cords that hang from the head box 12. 16, the multi-stage slats 18 constituting the shielding material are supported in an aligned state. 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 an elevating cord 14 as a plurality of operating cords hanging from the head box 12. One end of each lifting / lowering cord 14 is connected to the bottom rail 19, and the other end is inserted through the lifting / lowering cord insertion hole of each slat 18 and introduced into the head box 12, and then arranged along the longitudinal direction of the head box 12. Then, it is led out from an opening 12a provided at one end of the head box 12 through a stopper (not shown). The slat 18 is moved up and down by operating the end of the lifting cord 14 suspended from the opening 12 a of the head box 12.
[0015]
A bag-like member 22 is suspended from the periphery of the opening 12 a of the head box 12. The bag-like member 22 can be made of soft plastic, woven fabric, knitted fabric, non-woven fabric, etc., and is preferably lightweight and flexible, but can also be made of hard material such as hard plastic. And the outer peripheral surface of the bag-shaped member 22 is transparent or opaque, and the pattern etc. are attached | subjected and it is good for the designability to be considered. In the bag-like member 22, the vicinity of the end portion of the lifting / lowering cord 14 suspended from the head box 12 can be stored. That is, after the plurality of lifting cords 14 are led out from the opening 12a of the head box 12, they are connected to each other by the connector 20, and are further extended portions 14a, and a part of the extended portions 14a is formed on 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 extended portion 14a after being connected by the connecting tool 20 may be integrated with the lifting / lowering cord 14, or may be a separate one, or may not have the extended portion 14a at all. The plurality of lifting / lowering cords 14 may be stored in the bag-like member 22 and their ends may be connected to the bag-like member 22. When it has the extension part 14a, the raising / lowering cord 14 containing the extension part 14a comprises an operation code.
[0016]
In the blind operating device configured as described above, when the slat 18 is moved up and down, the extension 14 a of the lifting cord 14 housed in the bag-like member 22 is taken out. At this time, it is not necessary to take out all the extended portions 14 a of the lifting / lowering cord 14 from the bag-like member 22. After the lifting / lowering cord 14 is removed from the bag-like member 22 by a length appropriate for operation, the removed portion is slightly pulled downward to release the stopper. When the stopper is released, the lifting / lowering cord 14 can freely move. In this state, when the portion of the lifted / lowered cord 14 taken out is further pulled downward, the bottom rail 19 rises and sequentially rises from the lower slats 18. On the contrary, if the taken-out part is moved upward according to the dead weight of the bottom rail 19 and the slat 18, the slat 18 will fall. After the operation is completed and the stopper is fastened to prohibit the movement of the lifting / lowering cord 14, the portion of the lifting / lowering cord 14 taken out is stored in the bag-like member 22 again.
[0017]
Thus, when not in use, the plurality of lifting cords 14 are not separated but are suspended from the head box 12 as a bag-like member 22 as a whole, so that virtually one cord is suspended. Thus, it is possible to prevent an object or a person from being caught by the lifting / lowering cord 14.
[0018]
FIG. 3 is a front view showing an embodiment in which the blind operating device of the present invention is applied to a roll screen as a blind. In the figure, the blind 30 has a pair of side plates 34 attached to both ends of a set frame 32 attached to a window frame or the like by a bracket or the like, and a winding as a head box is interposed between the pair of side plates 34. A pipe 36 is rotatably supported. A screen 38 as a shielding material is supported on the winding pipe 36, and the upper end of the screen 38 is coupled to the winding pipe 36 so as to be capable of winding and unwinding. A weight bar 40 is connected to the lower end of the screen 38.
[0019]
The blind operating device of the present invention includes an operating portion 42 provided on one end side of the winding pipe 36. A pulley 44 is built in the operation unit 42. The clutch incorporated in the winding pipe 36 transmits the rotation of the pulley 44 to the winding pipe 36, while preventing the rotation from the winding pipe 36.
[0020]
An upper end of an endless operation cord 46 is wound around the pulley 44 in the operation unit 42, and the lower end of the operation cord 46 is led out from the operation unit 42 and hangs down. The operation cord 46 can be constituted by a ball chain.
[0021]
A bag-like member 48 is suspended by a suspender 47 from the side plate 34 around the lead-out of the operation code 46 of the operation unit 42. The bag-like member 48 can be made of plastic, woven fabric, knitted fabric, nonwoven fabric, or the like, like the bag-like member 22, and is preferably lightweight and flexible, but can also be made of a hard material such as hard plastic. It is. And the outer peripheral surface is transparent or opaque, and the pattern etc. are attached | subjected and it is good for the designability to be considered. In the bag-like member 48, at least the lower part of the operation cord 46 suspended from the operation unit 42 is accommodated.
[0022]
The bag-like member 48 has an opening 48 a formed on the side surface thereof, and the operation cord 46 inside the bag-like member 48 can be grasped and operated through the opening 48 a.
[0023]
Preferably, a pulley 50 around which the lower end portion of the endless operation cord 46 is wound is disposed in the bag-like member 48. The pulley 50 itself becomes a weight. However, if the weight of the pulley 50 alone is insufficient, the pulley 50 may be separately provided with a weight 50a, whereby the tension is always applied to the operation cord 46 by the pulley 50. 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 unevenness so that the operation cord 46 can slide smoothly.
[0024]
In the blind operating device configured as described above, when the screen 38 is moved up and down, the operating cord 46 is operated from the opening 48a in the state of the operating cord 46 stored in the bag-like member 48. When one end of the endless operation cord 46 is pulled downward, the pulley in the operation unit 42 rotates accordingly, the winding pipe 36 rotates in the same direction, and the screen 38 rotates to the winding pipe. The screen 38 is lifted or lowered by being unwound or wound up by 36. Further, when the other side of the operation cord 46 is pulled downward, the winding pipe 36 rotates in the opposite direction, and the screen 38 is lowered or raised.
[0025]
In this way, the endless operation cord 46 is always stored in the bag-like member 48 and is collectively suspended from the operation portion 42 as the bag-like member 48, so that virtually one operation cord is suspended. Thus, it is possible to prevent an object or a person from being caught by the endless operation cord 46. Further, since the operation cord 46 is tensioned by the pulley 50, the operation cord 46 can be easily operated in the bag-like member 48 without pulling the operation cord 46 out of the bag-like member 48. Can do. However, optionally, as in the first embodiment, when the endless operation cord 46 is used, the operation cord 46 may be taken out from the bag-like member 48 and stored again in the bag-like member 48 after use. 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 cord. The bag-like member can be manufactured in common regardless of the number of operation cords, and can be applied to any size and any kind of blind. That is, the present invention is not limited to the blind described in the above embodiment, and a bag-like 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 cost and component management cost can be reduced.
