Description

[Detailed description of the invention] This invention relates to a curtain device equipped with at least two rows of supports for pantograph-like link mechanisms, one above the other, and more specifically, one in which the supports are suspended from a curtain rail fixed to the ceiling, etc. The present invention relates to a curtain fabric mounting device that allows the curtain fabric to be attached and removed and the tension to be adjusted in the \ state.

Curtain devices that have a curtain fabric support made of pantograph-like link rows are often used as partitions because of their good shape stability.However, in conventional devices, the holes of the links are always closed in the lower part of the curtain fabric, apart from the upper part. The left and right edges of the curtain material are stapled to the wooden pieces that connect the left and right end brackets of the upper and lower pantograph-like link rows, thereby attaching the curtain material to the support.

In this type of installation, the support is suspended from a curtain rail fixed to the ceiling or the like, and it is completely impossible to change the curtain fabric or adjust the tension.

However, it is not easy to remove the support from the curtain rail.

This not only makes it impossible to install the curtain fabric at the construction site, but also makes it impossible to replace the curtain fabric or adjust the tension in a typical home.

The inability to easily replace the curtain material or adjust the tension is a major drawback, as it is common for the curtain material to become soiled, change in dimensions, or change in taste during use. There is a wide demand for a curtain device that can change the curtain material and adjust the tension while the curtain is suspended.

The purpose of this project, which attempts to meet such demands, is to make it possible to easily attach and detach curtain material by suspending a support made of pandagraph-like link rows from a curtain rail.
To provide a curtain device capable of adjusting the tension in the vertical direction.

It is also an object of the present invention to easily attach the left and right edges of the curtain material to a support in a similar manner without causing wrinkles.

The configuration of the present invention will be explained based on an embodiment shown in the drawings.

As shown in FIG. 1, the curtain device of the present invention includes a curtain rail 10 fixed to the upper surface of the interior of a building, a support 11 suspended from the curtain rail so that it can move and expand, and supports attached to the front and back of the support.
