Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a lintel used when three or more sliding grooves are formed in which a sliding door slides.

[Conventional technology]

Conventionally, lintels are made of highly durable metal materials such as aluminum, and are usually formed in one piece, so the width of the lintel and the sliding door must be adjusted according to the wall thickness of the wall to which the lintel is attached and the thickness of the sliding door. Since the lintels, which have the width of the slide groove in which the lintel slides, must be produced in small quantities of a wide variety of products, the production cost is high.

For this reason, a plurality of members are partially overlapped one on top of the other and screwed together, and by changing the overlapping width of the plurality of members, the groove width and the width of the entire band can be adjusted. -148185) and one in which multiple lintel members are connected horizontally by fitting the side edges of other lintel members into the insertion groove formed on the side surface of one lintel member (Utility Model Publication No. 47-41162). has been done.

[Problem that the invention attempts to solve]

However, the former method of overlapping lintels is complicated to assemble and there is no flexibility in terms of dimensions, so the width of the sliding groove in which the sliding door slides must be adjusted slightly depending on manufacturing errors and irregularities of the sliding door. Even if you want to increase or decrease the amount, there is a complaint that it is difficult to do it physically and operationally.

In addition, the latter can simply increase or decrease the number of sliding grooves on the sliding door, but does not have a function to adjust the groove width. Therefore, in order to change the groove width, all the parts must be replaced. The problem is that it does not.

The purpose of this invention is to provide a lintel that is easy to assemble, has flexible dimensions, allows fine adjustment of groove width, and allows easy increase/decrease in the number of slide grooves.
