Description

[Detailed Description of the Invention] (Field of Application) The present invention relates to an assembly type table, and particularly to an assembly type table using board materials such as paper.

(Prior art and its problems) One of the most commonly used sectional tables is one with the configuration shown in FIG. with bolts B on either the top plate side or the legs.
are planted and fixed, a pair of legs for attaching legs is provided on the top plate 1 side, and the upper end of the leg 2 comes into contact with the pair of legs by screwing.

This has the advantage that the legs 2, 2 can be attached to the corners of the top plate 1 without wobbling when screwed, but the top plate 1 requires a frame 10 of a certain height for the above-mentioned contact. Moreover, if the legs 2 are in the form of a flat plate, sufficient mounting strength cannot be obtained.

The object of the present invention is to enable the top plate 1 and the legs 2 to be assembled without wobbling even if the top plate 1 and the legs 2 are flat.

(Means) The technical means of the present invention for achieving the above object is to form first and second grooves 11 and 12 that intersect with each other on the back surface of the top plate 1, and on the other hand, the legs 20 are arranged in an intersecting shape. A pair of flat plate-shaped first and second plates that are interlocked with each other.
Consisting of leg plates 21 and 22, part or all of the upper end side of each leg plate is a fitting part 23 that fits into the groove, and at least one of the first leg plates 21 has a pair of bendable tongue pieces 3 in the fitting part. . Stoppers 32, 32 are provided on the bottom surface of the top plate,
This stopper is arranged to face the upper end side of the first leg plate so as to be able to move toward and away from it, and the position and size of the bag-shaped recess 31 are made to match the tongue pieces 3, 3.

(Operation) The above technical means of the present invention operates as follows.

Since the first and second leg plates 21 and 22 are engaged with each other in a cross-shaped manner, they do not slide against each other in this engaged state. Bend the tongue pieces 3, 3 of the first leg plate 21 in the horizontal direction, and
When the fitting part 23 of the first leg plate 21 is fitted into the first groove 11 and the fitting part 23 of the second leg plate 22 is fitted into the second groove 12 with the legs 2 and 32 retracted,
The tongue pieces 3, 3 are exactly housed separately in the bag-like recesses 31, 31, respectively. When the stopper 32 is brought into contact with the upper end side of the first leg plate 21 in this state, the end of the stopper 32 comes into close contact with the upper end side of the first leg plate 21 with each of the tongues remaining in the accommodated state, and this portion are pinched by the stopper 32 and the side wall of the first groove 11, and the tongues 3, 3 are held in the bag-shaped recesses 31, 31 so as not to come off. When the second leg plate and the second groove are provided with a combination of the tongue piece, the bag-shaped recess, and the stopper, the two leg plates are held together in a manner that prevents them from coming off.

(Effects) Since the present invention has the above configuration, it has the following unique effects.

The first and second leg plates 21 and 22 are non-slidably engaged with each other, and their upper ends are fitted into cross-shaped grooves, and one of the first leg plates 21 is connected to the stoppers 32 and 32. Since the legs 20 are press-fitted and fixed by frictional force, no wobbling occurs when the legs 20 are attached to the top plate 1.

Furthermore, when the stopper 32 is closed, the tongues 3, 3 are fixed to prevent them from coming off, so the top plate 1
There is no need to worry about the leg body 20 coming off even if you lift it.
