BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for mounting parts, such as receiving of various locking devices and door stop of shoji, which are mounted in a state in which the mounting parts fixed to the shape member with screws are covered with the screws. is there.

[0002]

2. Description of the Related Art A mounting made of synthetic resin, which is manufactured separately from a frame member such as a receiving device and a door stop of a lock device and is partially attached to a frame member such as a frame or a frame. Parts are usually fixed by screws that pass through the profile as shown in Fig. 13 and Fig. 14, but the screws are screwed directly into the profile from the surface side of the mounting part and are screwed into the profile so that they are attached to the mounting surface side. The head of the screw is exposed and the design of the profile is deteriorated.

The problem of exposing the screw is solved by screwing the screw into the mounting part from the back side of the profile, but it is necessary to give the plate thickness of the mounting part a size larger than the length of the shaft portion of the screw. Therefore, the mounting component itself becomes unnecessarily large, and when the profile has a hollow cross-sectional shape, it is impossible to screw the screw from the back surface.

The present invention has been made by paying attention to the problem of fixing a conventional mounting part with a screw, and proposes a new mounting structure for avoiding the exposure of the screw while reducing the plate thickness. .

[0005]

According to the present invention, the mounting parts are
Forming an engaging groove into which the head of a screw screwed into the mounting surface of the shape can be inserted, and providing a protrusion that engages with the shape, the engaging groove on the head of the screw and on the mounting surface. At the same time as engaging in the vertical direction, the protrusion is engaged with the mounting surface in the direction parallel to it to mount the mounting component on the shape member, eliminating the penetration of the screw into the mounting component and forming the shape of its head. Avoid exposing the surface of the material, and reduce the thickness of the mounting parts.

A screw is screwed into the mounting surface of the shape member from the surface side, and an engaging hole into which the protrusion is inserted is opened.

The engaging groove of the mounting part is formed on the mounting surface side so that the head of the screw can be inserted parallel to the mounting surface by sliding the mounting part, and the protrusion is inserted into the engaging hole at a position corresponding to the engaging hole. It is possible to project. The mounting part is formed in a state where the engaging groove engages with the screw in a direction perpendicular to the mounting surface and the protrusion engages with the engaging hole in a direction parallel to the mounting surface so that movement in the three-dimensional direction is restricted. Attached to the material.

The mounting part has elasticity, and a screw is inserted into the engaging groove by sliding along the mounting surface of the shape member, and the protrusion rides on the mounting surface due to elastic deformation of the main body and the engaging hole. Fit it in position.

When the screw engages with the engaging groove formed on the back side of the mounting part to restrain the mounting part from coming out, the head of the mounting part is covered with the mounting part, and the design of the profile is improved.

Further, since the screw does not penetrate the mounting part, it is not necessary to increase the plate thickness, and the screw and the mounting part are attached to the mounting surface from the front side of the shape member, so that the shape member has a hollow sectional shape. In the case of, the mounting parts can be mounted.
