Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to a device for joining two plate-like bodies, and is particularly effective when used for assembly furniture and the like.

Conventional technology In conventional assembly furniture, a rotatable hinge is attached to the inner corner of the joining part of the plate-shaped bodies to make the plate-shaped bodies rotatable, and then fixed by joining with other parts etc. during assembly. It had been assembled.

Problems to be Solved by the Invention However, with the above configuration, it is difficult to prevent gaps from forming at the joints between the plate bodies due to warping of the plate bodies or misalignment when installing the hinges. It was hot.

Means for Solving the Problems The plate-shaped body coupling device of the present invention provides a concave portion in the plate surface of the first plate-shaped body forming one side wall, and
A convex portion is provided at the end of the second plate-like body forming the other side wall, and with the convex portion engaged with the concave portion, the first plate-like body is inserted from the back side of the plate surface on which the concave portion is formed. The first plate-like body and the second plate-like body are fixed by passing the screw through the concave portion and screwing the screw into the side wall surface of the convex portion provided on the second plate-like body located in the recess.

Effects The present invention has the above-mentioned configuration, so that when screwing into one side wall surface of the convex portion with a screw, when the screwing operation starts, the other side wall surface portion of the convex portion moves so as to come into contact with the side wall surface of the adjacent concave portion. . When they come into contact and cannot be moved, the screws are screwed into one side wall of the convex part and the plates are fixed together.
There will be no gap at the joint between the plate-like bodies.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, a second plate-shaped body (hereinafter referred to as a back plate) 1 constituting a part of the furniture has a convex part 2 for the tenon part at the end of the wood, and this convex part 2 is attached to the first The back plate 1 and the side plate 3 are engaged with the recess 4 for the horizontal groove of the plate-like body (hereinafter referred to as the side plate) 3.
forms an L-shape.

A hinge 5 is provided on the inside of the corner formed by the back plate 1 and the side plates 3.
are rotatably connected to each other, and the side wall surface portion 8 of the convex portion 2 and the side wall surface portion 13 of the concave portion 4 are tapered so as to be rotatable around the hinge 5, making it foldable for storage or transportation. ing. Also, when assembling, return the back plate 1 and side plate 3 to an L-shape and insert the screw 7 through the hole 6 provided in the side plate 3 between each hinge 5 into the convex part 2.
It is screwed into the tapered side wall surface portion 8 of. In other words, when the screw 7 starts to screw in, the convex part 2 escapes and moves in the direction where the gap A at the joint part disappears, and when the side wall surface part 9 of the convex part 2 comes into contact with the side wall surface part 10 of the recessed part 4, the side wall surface part 8 It is bitten and screwed in, and finally the back plate 1 pulls in the side plate 3, fixing the back plate 1 and the side plate 3.

As a result, the gap A will disappear.

In this embodiment, a guide hole for the screw 7 is not provided in the side wall surface 8 of the convex portion 2, the back plate 1 is made of wood or an equivalent product, and the screw 7 is made of wood screws, JIS class 1 or Three types of tatsupin screws are used, but if you use wood screws or tatsupin screws that can be screwed in while processing the screws, you only need to prepare a pilot hole for the screw, and in addition,
The distance between the center of the pilot hole for the screw and the plate surface 11 is made longer than the distance between the center of the hole 6 and the side wall surface 10 so that the side wall surface part 9 and the side wall surface part 10 are in strong contact with each other. The center of the hole may be eccentric. In addition, 12 is a straight surface part and 13 is a side wall surface part.

FIG. 3 shows another embodiment with a tapered side wall surface 8.
The vicinity of the tip of the convex portion 2 is a straight surface portion 12 parallel to the plate surface 11. Furthermore, it goes without saying that the side wall surface portion 8 does not have to be tapered so as to be parallel to the plate surface 11 as long as the screw 7 can push the side wall surface portion 8 and the side wall surface portion 9 can contact the side wall surface portion 10 and be screwed into the back plate 1. stomach.

Effects of the invention As described above, the present invention has the advantage that the first
A screw passing through the first plate-like body is screwed into the side wall surface of the convex part of the second plate-like body that engages with the recess of the plate-like body, thereby fixing the first plate-like body and the second plate-like body. By doing so, it is possible to eliminate gaps between the joints caused by warping or the like occurring in both plate-shaped bodies, improve the appearance of the exterior, and prevent indoor pests such as cockroaches from entering the furniture.
