Embodiment Construction

[0060]

[0061] Embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

[0062] In this embodiment, the case where the lifting device of this invention is applied to a horizontal blind is demonstrated as an example. figure 1 It is a side view which shows the raising and lowering device of the horizontal blind which concerns on embodiment of this invention.

[0063] Such as figure 1 As shown, the horizontal shutter 1 is equipped with: a head box 2 fixed on the window frame, a ring-shaped operating rope 3 suspended from the side end of the head box 2, and a lifting rope 4 suspended from the head box 2 , and a direction control rope (rudder cord) 5 suspended from the upper beam 2 .

[0064] Furthermore, the horizontal blind 1 further includes a bottom rail 6 attached to the lower end of the lifting cord 4 and a plurality of blades 7 (shielding members) supported by the direction control cord 5 .

[0065] The direction c...

Abstract

The present invention has advantages of allowing a lifting string to be more easily replaced and lowering the assembly cost or the production cost for installing the lifting string. A lifting device of blind window provided by the present invention includes following structures: a structure for operating an operation string for ascending or descending a plurality of blades so as to enable the front end of a lifting string (4) reeled on a reeling shaft (14) or released from the reeling shaft (14) to be fastened on the reeling shaft (14); a cover member (40) mounted at one end of the reeling shaft (14) includes a string latching part (45), the string latching part (45) being disposed at a location opposite to the outer circumference of the reeling shaft (14) mounted with the cover member (40), and includes an opening (45c) formed at the opened side of the reeling shaft (14) and axially penetrated along the reeling shaft (14).

Description

technical field [0001] The invention relates to a lifting device for blinds such as horizontal blinds, pleated blinds or pull-up curtains. Background technique [0002] As a raising and lowering device of a blind, there exists what is described in patent document 1, for example. In this shutter lifting device, a blade operating device is provided on one side of the horizontally elongated upper beam fixed to the window frame in the lateral direction, and an operating rope hangs from the blade operating device toward the lower side of the upper beam. Furthermore, a blade lift shaft (drive shaft) is rotatably supported in the upper beam, and a cylindrical winding cone (winding shaft) for winding up and down ropes is mounted laterally on the blade lift shaft. [0003] In the lifting device with the above configuration, when the operation rope is operated in the direction of raising the blade, the blade lifting axis rotates in the winding direction of the lifting rope, so that t...
