Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an assembly type table, that is, a so-called knock-down type simple table that is handled in a compact disassembled state during transportation and storage, and is assembled and put into practical use when used.

Conventional Technology and Problems Conventionally, in this type of assembly table, the legs and top plate were assembled using separate screws, or a male screw was installed protruding from the top end of the rod-shaped legs. , which is generally screwed into a female threaded member embedded in the top plate side to connect the two. However, the former type has drawbacks such as being somewhat troublesome to assemble and being unsightly because the screw head is often exposed to the outside. In addition, the latter method has the disadvantage that the connection strength between the top plate and the legs remains unsatisfactory, and that it tends to rattle and become unstable due to repeated loads of large external forces.

This idea solves the above drawbacks,
That is, it is an object of the present invention to provide an assembly type table having a simple structure, which can be assembled extremely easily, has a good appearance, and is sufficiently robust in the assembled state.

Means for Solving the Problems For the above purpose, the assembly type table according to this invention is assembled into an L-shape in plan view by joining one side end surface of one leg plate to the one side edge part of the other leg plate. The top plate is placed on the legs arranged oppositely and has a lower surface joined to the upper end surface of each of the leg plates, and the top plate is connected to the top plate, and a pair of adjacent positioning protrusions and engaging protrusions is provided on one of the facing joint surfaces of the leg plate and the top plate, and the positioning protrusions are closely arranged in corresponding positions on the other joint surface. It is characterized in that it is provided with a fitting hole into which it fits, and an embedded female engagement member having a plurality of elastic engagement claws that engage with the engagement head of the engagement protrusion.

Embodiment In the embodiment shown in FIGS. 1 to 3, 1
is the top plate, and 2,2 are two sets of legs. The leg body 2 consists of two rectangular leg plates 2a and 2b of the same shape and size, and one end surface of one leg plate 2a shown in FIG. 2 is joined to the end edge of one side of the other leg plate 2b. As a result, they are combined into a substantially L-shape in plan view, and constitute one leg body 2. Then, as shown in Fig. 1, the top plate 1 is placed on top of the two legs 2, which are placed facing each other with a required spacing between them or without any spacing between them. , and by joining the lower surface of the top plate to the upper end surfaces of the leg plates 2, 2, the table can be assembled into a single table. The above joint structure, that is, the joint structure between the leg plates 2a and 2b constituting one set of legs 2, and the joint structure between the leg plates 2a and 2b and the top plate 1 are all the same. That is, as shown in FIGS. 2 and 3, one of the facing joint surfaces has a positioning projection 3 made of a round shaft.
and a set of both protrusions arranged adjacent to each other in close proximity to the engagement protrusion 4 having an enlarged engagement head 4a with an arrow-shaped cross section at the tip, both of which are annular retaining protrusions 3b, 4b.
The proximal end portions having the base ends are forcibly driven into the leg plates 2a and 2b, and one set or two sets are fixedly planted. Further, at corresponding positions on the other joint surface, there is a fitting hole 5 into which the positioning projection 3 is firmly and tightly fitted, and a plurality of fitting holes 5 which are engaged with the engagement head 4a of the engagement projection 4 in a manner that prevents them from coming off. An embedded female engaging member 7 having resilient engaging claws 6 arranged in a circular arrangement is provided.
The engaging female member 7 is made of synthetic resin together with the engaging protrusion 4, and is embedded in a predetermined portion of the leg plates 2a, 2b by driving a short cylindrical portion 9 provided with a retaining annular protrusion 8 on the outer periphery into the leg plate 2a, 2b. It is something that The elastic engagement claws 6 are integrally molded inside the short cylindrical portion 9 at a predetermined interval and folded back from one end thereof.

Regarding the positioning protrusion 3 and the engagement protrusion 4, the protrusion length of the positioning protrusion 3 is set to be larger than that of the positioning protrusion 3 in their mutual relationship.

The leg body 2' shown in Fig. 4 is a modified example of the shape of the leg plates 2'a and 2'b, in which one side is largely cut inward to form the leg plate into a substantially U-shape. It is something. Of course, other deformations may also be adopted.

When the table having the above structure is to be transported and stored, the top plate 1 and all the leg plates 2a and 2b are separated and stacked on top of each other as appropriate, and then packaged in a cardboard box or the like. When using the leg plates 2a and 2b, which form a pair of legs, first
are joined to assemble two sets of L-shaped legs 2, 2, respectively. This assembly operation begins with one leg plate 2a.
After the relative positioning of both leg plates 2a and 2b is achieved by fitting the tip of the positioning protrusion 3 into the fitting hole 5 at the corresponding position of the other leg plate 2b, it is then hardened by hitting it by hand or the like. This is done by forcibly fitting the engagement protrusion 4 between the elastic engagement claws 4a by applying force. The reason why the positioning protrusion 3 has a longer protrusion length than the engagement protrusion 4 is because
This is effective for facilitating the initial accurate positioning of both leg plates 2a and 2b.

Next, place the top plate 1 face down on the floor,
Place the legs 2, 2 upside down on top of that,
They are joined by the same operation as above, and the desired table assembly is completed.

Effects of the invention This invention has the above-mentioned configuration, and includes a top plate 1 and a leg plate 2 constituting the legs 2, 2.
Since both a and 2b can be formed into a flat plate shape without any protrusions on the front or back surfaces, the whole can be packaged in a very compact state when disassembled, and it does not take up much space to transport or store. It's very convenient.

Moreover, when in use, the leg plates and the top plate are strongly pressed together with their joint surfaces facing each other, and the positioning protrusion and the engagement protrusion have corresponding fitting holes and elastic merging claws. By fitting into the engaging female member, any other separately fixed member,
For example, it can be easily assembled without using screws or the like. Moreover, in the assembled state, the legs consist of two sets of two leg plates each having an L-shape, and the top plate is placed on top of these, which are arranged facing each other. It is inherently more stable than the table used, and the tight fit between the positioning protrusion and the fitting hole in each joint between the leg plates and between the leg plate and the top plate allows the joint members to be positioned with respect to each other. While the engagement between the engagement protrusion and the engagement claw plays the role of firmly holding the members in a state where no displacement occurs, the engagement between the engagement protrusion and the engagement claw also serves to reliably prevent the members to be joined from coming apart from each other.
The table can be made very sturdy in the assembled state, and can be made to have excellent durability without wobbling over a long period of time even when used under relatively harsh conditions. Furthermore, the joint parts such as screws are not exposed at the joint parts of each member, and the appearance is good, and the appearance is unique due to the opposing arrangement of the pair of L-shaped legs. It can also be made with excellent design.
