Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cross panel whose surface is covered with a cloth, which is used as a partition or a blindfold panel in an office work space or the like.
[0002]
[Prior art]
In constructing this type of cross panel, a technique of adhering a cross to a substrate surface has been widely used. However, in this method, since the base material exists in the center, it becomes a heavy aspect. This kind of panel could not be considered to reduce the feeling of pressure and provide daylighting. In addition, since there is a process called bonding, it takes a lot of processing steps and there is a problem in separating and discarding because different materials are bonded.
[0003]
Because of these problems, a method of forming a cross panel by providing a groove in a rectangular frame-shaped frame and pushing a cloth and a core material into the frame (see, for example, Patent Document 1), There is a method of forming a cover so as to cover the whole, and sewing a member that closes the cloth in a hollow shape, such as a fastener or a hook-and-loop fastener, on three sides of the cloth (see, for example, Patent Document 2).

[Problems to be solved by the invention]
However, in the former, when a soft material such as a cloth is attached to the frame, it is attached to a groove formed on the side surface of the frame, so that the front and back of the panel appear, and the aesthetics are lacking. In addition, the screen cloth is applied to the groove formed on the entire periphery of the frame, and the work of pushing the cloth and the core material into the groove is required to have a uniform tension and is easy. It is not work.
[0006]
The latter is formed so that the cloth covers the entire frame, so the cloth is doubled in the front and rear, and a large amount of cloth is required. Moreover, since different materials such as fasteners and hook-and-loop fasteners are sewn, it is not easy to separate the materials during recycling. In addition, a mesh-like cloth having excellent daylighting is doubled, so that a moire pattern is generated, which is not visually attractive.
[0007]
In view of the above-mentioned problems, the present invention provides a cross panel that does not require any special technique for attaching a screen cloth to a frame, is beautifully stretched, is low in cost, and can be easily separated in recycling. It is aimed.

【The invention's effect】
According to the first aspect of the present invention, it is possible to simply and quickly stretch the cross beautifully by simply tensioning the cross and joining the both ends of the lower horizontal reed to the left and right vertical reeds. Therefore, it is possible to obtain a cross panel that can be used as a partition or as a blindfold at low cost and has a beautifully raised and light feeling. Moreover, material separation at the time of recycling becomes easy.
[0028]
According to the second aspect of the present invention, the cross can be easily stretched without requiring skill only by inserting the frame into the bag-like portion formed on the edge of the cross. In addition, since the cloth is single, the material can be minimized, and desired translucency and air permeability are ensured. In particular, in the case of a mesh cloth, a moire pattern does not occur.
[0029]
According to the third aspect of the present invention, the frame and the lower horizontal bar extending between the lower ends of the vertical bar can be easily and reliably connected.
[0030]
According to the invention of claim 4, since the lower corner portion of the cross is covered by the cross cover portion, it can exhibit a beautiful appearance, and even if the cross may be displaced during use of the panel, Since the hole or void formed in the lower corner is hidden by the cross cover portion of the coupling member and cannot be seen, beauty can be maintained.
