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 two 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) 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. 9 of the present specification shows the mounting structure (1). In FIG. 9, 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. FIG. 5 of Patent Document 1 also shows the mounting structure (1).

However, with the mounting method described in (1) above, if the lower screw is removed for some reason, if the inspection cover receives an upward impact from below, the upper hook of the inspection cover will come off. There is an accident that the cover falls. In addition, with the mounting method described in (2) 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.

It is an object of the present invention to provide a frame and cover body mounting structure in which the cover body is attached to the frame even if an impact from the bottom to the top is applied to the cover body when the fixing means at the lower part of the cover body is removed. It is to prevent it from coming off the body.

The technical means adopted by the present invention is that, in the mounting structure of the frame body and the cover body, the frame body has an upper surface portion extending horizontally, and a hooked portion is provided at the front end of the upper surface portion. The cover body is provided with a surface portion, and an upper end of the surface portion is formed with a hooking portion for hooking on the hooked portion, and a tip of the hooked portion is covered. A latch piece is formed at each of the latch piece and the tip of the latch portion, and the latch portion and the latch portion are formed by latching the latch piece on the latch piece. The hooked state is an attachment structure between the frame body and the cover body that is held until the cover body is rotated upward from the vertical posture by a predetermined angle with the upper end as a fulcrum. In a preferred embodiment, the predetermined angle is approximately 90 degrees. The present invention is particularly characterized in the structure for attaching the upper part of the cover body and the frame body. The lower part of the cover body is detachably fixed to the frame body using a fixing means such as a screw (via a fixing member if necessary).

In one preferable aspect, the said latching piece is provided with the vertical piece and the horizontal piece extended horizontally from the upper end of a vertical piece, and the said latching piece is a horizontal piece extended horizontally. And an inclined piece extending obliquely downward from the tip of the horizontal piece. In the hooked state, the inclined piece of the hook piece is hooked on the horizontal piece of the hooked piece. Further, the shape of the hooking piece and the hooking piece may be reversed, and in this aspect, the hooking piece includes a vertical piece, an inclined piece extending obliquely upward from the lower end of the vertical piece, The latching piece includes a horizontal piece and a vertical piece extending downward from the tip of the horizontal piece, and in the latched state, the slanted piece of the latched piece includes the inclined piece. The vertical piece of the hook is hooked.

In an embodiment to be described later, the hooked portion includes a concave portion having an opening on the upper side, and the cover body is in a state where the surface portion is in a substantially horizontal posture, and the hooking portion is placed on the hooked portion. It is inserted into a recess, and the surface portion is rotated downward until it is in a vertical posture so that the latching portion is latched on the latched portion. More specifically, the latched portion is a recess. A first piece that forms the rear surface, a second piece that forms the bottom surface, a vertical third piece that forms the front surface, a horizontal fourth piece that extends rearward from the upper end of the third piece, And a recess opening is formed between the tip of the fourth piece and the first piece, and the latching portion extends horizontally from the upper end of the surface portion toward the rear. A first piece and an inclined second piece extending obliquely downward from the front end of the first piece toward the front, and the latched portion and the latched portion of the latched portion The state, hooking piece formed from a first piece and a second piece retainers are hooked onto hooking piece and a third piece and the fourth piece of the hook portion.

In the mounting structure of the present invention, the latching state of the latching portion and the latching portion is configured so that the cover body is not released unless it is rotated upward by a predetermined angle with the upper end as a fulcrum. Even if an upward impact is applied to the cover body, the cover body does not come off the frame body.

In order to remove the upper part of the cover body from the frame body, “the cover body is rotated upward and the latching piece at the tip of the latching part and the latching piece at the tip of the latching part The two actions of “releasing” and “pulling the latching part of the cover body from the latching part of the frame body” are required, so that the risk of the cover body falling off becomes very small. Further, at the time of inspection, as described above, the cover body can be rotated upward and the cover body can be pulled out of the hooked portion of the frame body, so that the mounting structure according to the present invention can be used for inspection work. There will be no hindrance.
