Description

The present invention relates to an attachment structure between a frame body and a cover body. In a preferred embodiment, the present invention relates to an attachment structure between an upper frame body constituting an upper frame of a sliding door device and an inspection cover.

In a sliding door device installed at the entrance of a living room such as a hospital, the upper frame above the opening is composed of an upper frame main body and an inspection cover that is detachable from the upper frame main body for installation and maintenance. ing.

Conventionally, there are the following three types of methods for attaching the inspection cover.
(1) Hook the upper part of the inspection cover to the upper frame body and fix the lower part of the inspection cover with screws.
(2) Insert the upper part of the inspection cover into the upper frame body and fix the lower part of the inspection cover with screws.
(3) The upper part of the inspection cover is rotatably connected to the upper frame body using a hinge, and the lower part of the inspection cover is fixed with a screw or a magnet.

FIG. 5 of Patent Document 1 and FIG. 19 of this specification show the mounting structure (1). In FIG. 19, a hooked portion 82 is formed at the tip of the upper surface portion 81 of the upper frame body 8, and a hooking portion 92 is formed at the upper end of the surface portion 90 of the inspection cover 9. The hooking portion 92 is simply hooked on the hooked portion 82.

However, with the mounting method described in (1) and (2) above, if for some reason the lower screw is removed, if an upward impact is applied to the inspection cover, the upper portion of the inspection cover is hooked. An accident has occurred where the inspection cover falls off and the inspection cover falls. In addition, with the mounting method described in (3) above, the possibility of the inspection cover falling is reduced, but the cost is high and the inspection cover cannot be removed. There is a problem that workability is poor because it must be supported. Furthermore, in the case of using a hinge, there is a problem that the workability is poor because work such as attaching the hinge with the position adjusted at the site is required.
