Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting device for raising and lowering a slat of a horizontal blind, or a lifting device for operating a pleated curtain or a lift curtain.

[0002]

2. Description of the Related Art In a horizontal blind, a plurality of slats are suspended from a head box via a plurality of ladder cords, and a bottom rail is suspended from the lower end of the ladder cord. Also, a plurality of lifting cords are inserted into each slat, one end of the lifting cord is connected to the bottom rail, and the other end is guided into the head box and connected to the operating device.

The slats are raised and lowered by raising and lowering the bottom rail via a lifting cord based on the operation of an operating device. Further, based on the operation of the operation device, the angle of each slat is adjusted in phase with the ladder cord.

[0004] As one type of the operating device, a gear mechanism is provided in a head box, and an input shaft of the gear mechanism protrudes out of the head box through an opening provided in the head box. The operation rod is connected to
Some slats can be adjusted in angle by rotating the operation rod.

In addition, the lifting cord is guided to one side in the head box, and hangs out of the head box through a weight drop prevention device provided in the head box. Then, when the lifting cord is pulled out from the head box, the bottom rail is pulled up. When the lifting operation of the lifting cord is stopped, the self-weight drop prevention device is activated, and the slat and the bottom rail are suspended and supported at desired positions. Further, when the operation of the self-weight drop prevention device is released, the slats and the bottom rail are lowered based on their own weights.

In such a horizontal blind, an operating device is provided at either the right or left end of the head box, and an operating rod and a lifting cord are hung from the operating device.

Therefore, there is a problem that the horizontal blind assembled for the left operation cannot be used for the right operation and the horizontal blind assembled for the right operation cannot be used for the left operation.

Therefore, in the horizontal blinds described in JP-A-6-200685 and JP-A-9-78963, an opening is provided from the bottom surface of the head box to the lower part of the side surface at the mounting position of the operating device. To rotate the operating device so that the operating rod and the lifting / lowering cord can hang down to the rear side of the head box.

In such a horizontal blind, if the operating device is rotated in the head box to select a direction in which the operating rod is hung from the head box, and the operating rod is installed so as to protrude into the room, The same horizontal blind can be used for left or right operation.

[0010]

However, in the above-mentioned horizontal blind, when the direction of hanging of the operating rod from the head box is changed at the installation site, the head box is removed from the mounting surface and then the head box is removed. It is necessary to remove the spacer that fixes the gearbox inside, rotate the gearbox, and attach the spacer.

Therefore, there is a problem that the operation for changing the operation direction by rotating the gear box in the head box becomes complicated. Also, when rotating the gearbox, the slats may be bent because the slats may interfere with the input shaft of the gearbox or the operating rod suspended from the input shaft and the slats may be bent. However, there is a problem in that the operation for rotating the gear box is complicated.

An object of the present invention is to provide an elevating device for a solar shading device which can be easily changed to a left operation or a right operation.
