Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention is mainly used for various three-dimensional bay windows in a house, and is used in such a manner that a blind moves up and down along each window glass which is assembled at various angles. The present invention relates to a pleated blind that can be bent in a second direction.

[0002]

2. Description of the Related Art Conventional blinds are disclosed in, for example,
As shown in JP-A-3-36948, each end of a plurality of upper end operation ropes is fixed to an upper end of a bellows-like blind plate which is vertically expandable and contractible, and a plurality of lower end operation ropes are attached to a lower end of the blind plate. Were fixed, and a blind plate was suspended by the upper and lower operation ropes.

[0003]

However, the conventional blind has a structure in which one blind plate expands and contracts only in the vertical direction. For this reason, in a flat window provided on the wall of a house, one side of one blind plate may move up and down along the window glass to block light entering the room. In various types of three-dimensional bay windows provided with a single blind board,
It was not possible to ascend and descend along each glazing of bay windows assembled at various angles.

On the other hand, in order to move up and down one blind plate along each window glass constituting a bay window, means for bending several portions of the blind plate in a horizontal direction is also employed.

[0005] However, since a specific portion of the blind plate is folded and the blind plate is bent at a predetermined angle, there is a problem that the folded portion becomes unnaturally thick.

Further, fine adjustment of the bending angle of the blind plate cannot be performed.

Furthermore, since the blind plate is folded at a predetermined angle by folding a specific portion of the blind plate, the bending angle of the blind plate coincides with the upper and lower portions of the blind plate by the restoring elastic force of the folded portion. There were also negative effects.

In view of the above-mentioned problems, the present invention is designed to bend horizontally in order to raise and lower the blinds along each window glass such as a bay window which is assembled at various angles. It was devised to provide pleated blinds as possible.

[0009]

For this reason, the present invention comprises a plurality of sheets provided with accordion-shaped pleats and a connection hole formed at the end thereof, and the connected sheets can be bent in the horizontal direction. In order to solve the above-described problem, the ends of the adjacent sheets are overlapped to insert the operation code into the connecting hole.

[0010]

According to the present invention, the ends of the sheets provided with the connection holes are overlapped, and the elevating operation cord is inserted into the connection holes. Then, in order to raise and lower the sheet along each window glass such as a bay window which is assembled at various angles, each connected sheet is bent at a predetermined angle using the lifting operation code as a fulcrum and used.
