Stringed vertical curtain

Abstract

The invention discloses a link vertical curtain, comprising a plurality of vertical curtain leaves. It is characterized in that: said curtain leaf is linked with two or more than two leaf boards through connecting unit in vertical direction. The invention overcomes shortcoming of flexural deformation caused by shrink and swelling, the bending between leaf board is free, which avoids warping deformation caused by timber stressing, the storage and transportation are convenient and production and maintenance cost are greatly reduced.

Description

technical field [0001] The present invention relates to a vertical blind. Background technique [0002] A blind (including door curtains, curtains, etc.) composed of multiple vertically suspended curtain leaves is called a vertical blind. In the current vertical blind product market, the traditional materials are mainly cloth and PVC. Recently, aluminum sheets are also used, and some people try to use wood to make vertical blinds, but many problems have arisen, so there has been no very successful example, which restricts vertical blinds. Applications. [0003] In traditional vertical blinds, each leaf is made of a whole piece of long sheet material suspended vertically from top to bottom. Whether it is PVC, aluminum or wood, it is easy to bend and deform. The longer the leaf , the greater the amount of deformation, not only affects the aesthetics of the vertical curtain, but also affects the shading and blocking functions of the vertical curtain. Especially for wooden ve...

Problems solved by technology

[0003] In traditional vertical blinds, each leaf is made of a whole piece of long sheet material suspended vertically from top to bottom. Whether it is PVC, aluminum or wood, it is easy to bend and deform. The longer the leaf , the greater the amount of deformation, not only affects the aesthetics of the vertical curtain, but also affects the shading and blocking functions of the vertical curtain

Especially for wooden vertical curtains, the curtain leaves are made of whole wooden strips. Affected by the physical phenomenon of cold shrinkage and thermal expansion, the leaves are easy to bend from the sunny side to the back side, and are limited by different wood materials. Wood is also prone to natural deformation and warping due to stress.

[0004] At the same time, traditional wooden vertical blinds do not have the softness of other ordinary vertical blinds, they cannot be bent and bent at will, it is inconvenient to carry and store, and the production cost is high (because the required length of wood is extremely high, and wood that meets this requirement Very expensive, in addition, the loss rate of curtains with different heights is very high), and the maintenance cost is high (the whole piece of wood needs to be replaced if it is damaged)

Traditional wooden vertical blinds are less variable in appearance, and it is difficult to make breakthroughs in appearance design

Traditional wooden vertical blinds are difficult to be compatible with existing vertical blinds in the use of spare parts, and almost all spare parts need to be specially made
