Description

[Detailed explanation of the invention] When assembling furniture or making picture frames, vertical and horizontal materials are assembled into frames of various sizes, and the joints of these frames are made with shredded pieces. However, as time passes, unsightly gaps or cuts occur, reducing the product value.

The present invention aims to eliminate such drawbacks, and an example of implementing the present invention will be described below with reference to the drawings.

In FIG. 1, numeral 1 is a horizontal member, and 2 is a vertical member, both of which are exploded perspective views of the back side. As seen in the drawing, the edge of the cross member 1 (one edge is shown in the illustrated example, but the same applies to the other edges) has a neck portion b.
An engaging body 3 consisting of a and a head a is provided. Here, the width s'' of the neck part b is 1/4 to 5/6 of the width S of the face material from the center position of the edge of the face material, and is formed into a pair of S-shaped shapes that become narrower inward. Constrictions 4, 4' are formed.On the other hand, the width s' of the head body a is equal to or slightly smaller than the face material width S (about 5 mm).On the other hand, the neck part b and the head body The overall protrusion length l of the engaging body 3 formed by the body a is determined by the vertical wall member 2 described below.
The dimensions are approximately 2/3 of the width S of the face material, the ratio of each of the neck part b and the head body a is 1/3, and the wall thickness h is approximately 1/2 of the overall thickness H. ~1/3 range,
Further, the wall thickness h'' of the head a is made thicker than the wall thickness h of the neck, so that a hanging jaw piece p of a certain length is formed on the lower surface of the head a.

Next, a recess 5 is bored in the vertical panel 2 into which the engaging body 3 having the above structure is inserted. Here, the shape of the recess 5 is the same size as the neck part b and the head a on which the hanging jaw piece p of a certain length is formed on the lower surface, and the depths h' and h'' are the same as the wall thicknesses h and h. '', and the two surfaces form the same plane when engaged and fitted.

FIG. 2 is a perspective view of the joining surfaces of the horizontal member 1 and the vertical member 2 configured as described above, which are fitted and fixed using an adhesive such as BOND (trade name).

The present invention is constructed as described above, in which the horizontal member 1 and the vertical member 2 are an engaging body 3 formed by a neck portion b and a head a having a hanging jaw piece P of a certain length formed on the lower surface. This ensures a firm fit and fixation. This is because the vertical panels 2 are engaged with the necks of the horizontal panels 1, and even if a force is applied that bends or distorts each panel as time passes, that force will be suppressed. In addition to being received by the bent part of the neck part b so as to offset it, the torsional force of each face material is sufficiently resisted by the hooking of the jaw piece p, and a very strong fixation is achieved. This eliminates the possibility of causing unsightly cuts in the joining line on the surface. In addition, with this product, the density of the adhesive surface (adhesion area)
Because of the high bonding properties, it is possible to achieve stronger adhesion than any conventional product. In addition, in the manufacturing process of this product, a certain amount of time is required for the adhesive to harden after being applied to a large number of products (approximately 50 to 100 sets).
Because it is possible to stack the materials and simultaneously press and fix them with a constant pressure using a press machine,
It does not take up much space, is extremely easy to manufacture, and can be manufactured at low cost without the need for troublesome man-hours or fixing means such as conventional baggies.

In the present invention, the engaging body 3 of the horizontal member 1 is created and the recess 5 in the vertical member 2 into which the engaging member 3 is inserted.
The drilling can be easily created by a router. In this example, the engaging body 3 is formed on the horizontal member 1, and the recess 5 is formed on the vertical member 2, but the configuration may be reversed.

Claims (1)

[Scope of Claim for Utility Model Registration] An engaging body consisting of a neck and a head having a hanging jaw piece of a certain length formed on the lower end of either the vertical panel or the horizontal panel is protruded. The neck is symmetrical and formed into an S-shaped constriction, and the neck width S'' is 1/4 to 5/6 of the width S of the facing material. A face material assembly frame characterized in that a recess into which the engaging body is inserted is formed in the part, and both parts are solidified with an adhesive.
