DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door check mounting structure, and more particularly to a door check mounting structure of an opening / closing door used for a panel, for example.

[0002]

2. Description of the Related Art A panel to which a conventional door check is attached is provided with a honeycomb core or an aluminum frame material between two panels made of a thin steel plate or the like so as to have strength in a thickness direction of the panel. Further, a decorative cover is attached to an edge of the panel so that these internal structures cannot be seen from the outside.

[0003]

However, when the aluminum frame material is provided inside the panel or the decorative cover is provided at the edge of the panel, not only the panel itself becomes heavy but also the number of parts becomes large. As a result, it takes time to assemble the panel.

In order to solve this problem, it is conceivable to form a panel by bending the edges of the panel twice in the same direction to form joints parallel to the panel and bonding these joints to each other. With such a configuration, the bent portion can provide strength in the thickness direction of the panel, and has an advantage that an aluminum frame or the like is not required. In addition, since the inner side of the panel is bent to make the internal structure invisible, a decorative cover is not required, and the panel can be further reduced in weight.

However, in such a configuration in which only the edge of the thin steel plate is bent, the strength in the thickness direction can be relatively increased at a portion away from the edge even if the edge can be given strength. Will be weaker. So, for example,
When a panel is used as a door panel, if the door check is attached to the panel as it is, the strength of the panel cannot be tolerated only by the thickness of the panel.

[0006]

Therefore, in order to solve the above-mentioned problems, the present invention reinforces the door check mounting portion of the opening / closing door without losing the weight of the opening / closing door composed of panels or the like. Provide strength in the thickness direction of the door.
