【Example】

 Next, an example of implementation of the present invention will be described with reference to the drawings. FIG. 1 is a front view of an example of an engaging member used in the present invention, FIG. 2 is a plan view of the same, FIG. 3 is a front view of a main part with a panel-shaped leg member attached to a top plate, and FIG. FIGS. 5 and 6 are front views showing another example of using the engaging member and the engaged member, respectively, with the leg plates attached to the top plate.

In the figure, reference numeral 1 denotes an engaging member, which is provided with an engaging member 11 having a horizontally elongated rectangular parallelepiped-shaped main body and a lower end on the front end side, whose upper surface is slightly inclined upward and which is formed into an uneven engaging surface 12. And two mounting holes 13 are provided for mounting. Reference numeral 2 denotes a table top plate as an example of a top plate, the length of which is twice as long as that of the engaging member 1, and the width and the depth of the engaging member 1 are the same at four positions on the back surface 2a of the flat portion. A groove 21 having substantially the same width and height as that of the engaging member 1 is provided so that the engaging member 1 can be embedded and mounted, and the engaging member 1 has the engaging surface 12 of the engaging member 11 directed to the inside of the groove. The rear end side is moved closer to the starting end of the groove 21 and fixed to the top plate 2 by a mounting screw 22, so that the engaging member 1 is not exposed from the horizontal direction of the top plate.

Reference numeral 3 denotes a panel-shaped leg plate which is an example of a leg member, and an engaging member having the same shape and structure as the engaging member 1 is used as an engaged member 4 on the flat upper end surface thereof. When the member 1 is turned in the opposite direction, the engaged surface 42 of the engaged member 41 faces downward, and the mounting screw 31 is fixed through the mounting hole 43.

Thus, in order to join and attach the leg plate 3 to the top plate 2, the engaged member 4 is placed inside (the facing member 11 of the engaging member 1 of the top plate 2 facing the engaged member 4). The upper end surface of the leg plate 3 is abutted against the back surface of the top plate 2 so as to fit into the open portion of the groove 21 of the top plate 2 on the matching side), and the inside of the groove 21 is directed toward the engaging member 1. The engaged surface 42 formed by the unevenness of the engaged element 41 is engaged with the engaging surface 12 formed by the uneven surface of the engaging element 11 of the engaging member 1 by sliding. Here, since the engaging element 11 and the engaged element 41 are elastic, and the engaging surface 12 and the engaging surface 42 face each other with their upper surfaces facing upward, the coupling of the engaging element 11 and the engaging surface 42 is performed. The engaged member 41 and the engaged member 41 are slightly elastically deformed, and after the connection, the elastic connection results in a tightening connection.

By doing so, the engaging member 1 and the engaged member 4 are elastically deformed and coupled to each other in the engaging members 11 and 41 of the both members in the groove 21, and after the coupling, the elastic member is tightened by the elastic force. Therefore, the top plate 2 and the leg plate 3 are in a butt joint state in which they are firmly connected to each other without coming off. Therefore, the engaged members 4 fixed to the upper end surfaces of the four leg plates 3 are engaged with each other in the respective grooves 21 formed on the back surface 2a of the top plate 2 so as to face each other in a flat V shape. By engaging the member 1, the four leg plates 3 are attached to the top plate 2 in a dogleg shape facing each other when viewed from the plane, and the bottom end side of each leg plate 3 is used as an example for connecting the dogleg shape. If fixed with the auxiliary metal fitting 5, a table is formed and the connecting portion between the top plate 2 and the leg plate 3 is not exposed to the outside, so that the appearance is very good.

In the above embodiment, the engaging member 1 and the engaged member 4 are usually molded products of synthetic resin or metal, and in order to attach them to the top plate 2 and the leg plate 3, the top plate is used. 2 and the leg plate 3 are embedded with the demon nut N in advance. In addition, in the above-mentioned embodiment, an example in which two panel-like leg plates 3 are arranged as leg members so as to form a plane V shape and are attached so that they are opposed to each other on the left and right sides of the top plate 2. However, the leg member in the present invention is not limited to the above-mentioned embodiment. That is, it suffices if the surface of the top plate 2 in contact with the back surface 2a has a flat surface on which the engaged member 4 can be attached.

Further, the above-mentioned embodiment is an example of joining and attaching the top plate and the leg member in the table, but in the joining structure of the present invention, the joining surfaces of one member to be joined and the other member are joined. Any flat surface can be applied. Therefore, in addition to the joint attachment of the table top plate 2 and the leg plate 3 in the above example, butt joint attachment of the top plate of the desk or counter and the leg member, the side plate and the top plate, and the bottom plate of the shelf or cabinet. It can be applied to the butt-joint mounting, or the butt-joint mounting of the seat plate and leg members of wooden chairs and tools. Here, the zenith plate in the present invention refers to a top plate, a deck, a seat plate, etc., which is attached at a butt angle of a vertical member such as a leg member, which is orthogonal to the vertical member and other angles.

The present invention replaces the two engaging members 1 and the engaged members 4 used for the joint attachment in the above embodiment, and replaces the engaging members 11a and 11b and the engaged members 41a and 41b shown in FIGS. It is also possible to use a joining structure that uses the engaging members 1a and 1b and the engaged members 4a and 4b that are in an engaging relationship with each other. The same reference numerals as in FIG. 1 indicate the same members and the same parts.

In addition, the attachment mode of the engaging member 1 and the engaged member 4 attached to the member to be joined such as the back surface of the top plate and the upper end surface of the leg member is also the plane shape of the attaching portion such as the upper end surface of the leg member. According to the size, size, etc., two or more of the engaging members 1 and the engaged members 4 may be vertically arranged in the longitudinal direction thereof, or may be provided in parallel in the lateral direction. You can also Incidentally, when the leg members on the left and right of the top plate are each one member, the connecting auxiliary metal fitting 5 becomes unnecessary.
