Description

[Detailed description of the invention] Industrial field of application This invention relates to a door frame for a shoji screen that constitutes a small window such as a revolving window, a folding window, or a sliding window.

Conventional technology Conventional door frames are assembled by assembling the upper and lower frames and side frames with a joint.
It is a structure that is fixed with screws, and requires a considerable amount of assembly time, which has a significant effect on small windows.

Purpose of the invention This invention was devised in order to solve the above-mentioned conventional problems and in view of the fact that it has become possible to increase the size of extruded aluminum moldings in recent years. The object of the present invention is to provide a door frame which is designed to save energy by simplifying assembly labor and reusing cut-out parts.

Structure of the invention The door frame according to the invention has cannilus mounting flanges with a generally groove-shaped cross section integrally formed only on two opposing sides of a rectangular plate, and has an opening in most of the center of the rectangular shape. It is characterized by having a rectangular frame shape.

Example The details will be explained below with reference to illustrated embodiments.

The door frame 1 is integrally formed by extrusion molding of aluminum or plastic, and has mounting flanges 2, 2 that are groove-shaped only on two opposing sides of a rectangular plate, for example, on both sides of the plate, or only on the top and bottom sides as shown. is formed, and an opening 3 is cut out in most of the central portion.

The whole frame has a rectangular frame shape.

Therefore, the part of the member from which the opening is cut out can be reused.

If necessary, a stop plate 4 separate from the door frame 1 is provided on both sides of the door frame 1 to prevent the glass plate 5 and other decorative plates fitted between the upper and lower mounting flanges 2, 2 from falling out (see Figure 2). ).

This plate 4 is fixed by screwing into screw holes 6 in the upper and lower frames.

Further, the illustrated door frame 1 is a projecting window, and a pivoting flange 7 is protruded from the upper end thereof and is fitted so as to be rotatable relative to the window frame 8, and its lower end abuts against the rising side of the window frame 9. As such, the flange 10 protruding from the waist door frame 1 and the window frame 9 can be locked with a temporary lock 11.

Effects of the invention This invention is effective because of the above-mentioned structure.The door frame can be constructed as an integrated door frame simply by cutting out a hole in the center of the extruded molded material, so there is no need for assembly, and there is no need for disassembly or damage. I never reach it.

In addition, this door frame can be integrally molded with other parts such as pivot flangs and airtight material mounting flanges in addition to the glass mounting groove, and can be fully automated and mass-produced.
