The chair 1 shown in FIG. 1 is a prefabricated chair 1 in which the seat plate part 200 and the backrest part 100 are assembled.

First, the seat plate 200 has a plurality of legs protruding downward and the user's hip is seated on the upper portion.

In the figure, the legs are illustrated so that the four frames protrude downward to support the seat plate 200.

And two of the legs are formed to protrude to the upper portion of the seat plate 200 is coupled to the backrest portion (100).

As shown in FIG. 2, the assembly module 300 is formed where the seat plate 200 and the backrest 100 are coupled to each other. That is, the seat plate 200 is disposed at the lower portion of the assembly module 300, and the backrest portion 100 is disposed at the upper portion thereof.

The assembly module 300 includes an accommodation part protruding upward from the two legs and a protruding part protruding downward from a part of the backrest part 100 to be inserted into the coupling space.

The protruding part will be described in detail with reference to FIG. 3.

As shown in FIG. 3, the head part is divided into an insertion region 302 and a separation prevention region 301.

At least one first rib 330 is formed in the insertion region 302, and the separation prevention region 301 includes a second rib 340, an elastic ring 310, and a variable part 320.

First, the first rib 330 is tapered in a shape in which the diameter increases toward the backrest part 100 in the seat plate part 200 and is formed in a ring shape protruding outward from the periphery of the protruding part.

In other words, the first rib 330 is provided in the form of a tapered ring which gradually increases in diameter, and the tapered shape is formed to increase in diameter in the direction toward the other end from the end inserted into the accommodation part in the protruding part.

As shown in FIG. 3, three are arranged at uniform intervals on the insertion region 302.

In addition, separation prevention regions 301 are formed at upper and lower sides of the insertion region 302 along the longitudinal direction of the protruding part.

In the separation prevention region 301, the second rib 340 has a tapered ring shape so as to increase in diameter in a direction opposite to the first rib 330.

The case where the protruding part is assembled to the insertion part will be described with an example. The protruding part is provided long in the vertical direction, and the variable part 320 is formed under the second rib 340.

The variable part 320 is formed to be tapered in the same direction as the second rib 340, but is tapered to have a larger diameter toward the bottom.

In detail, the portion having the largest diameter in the variable portion 320 has the same diameter as the portion having the smallest diameter in the first rib 330 or the second rib 340.

In this manner, the protruding part is integrally formed with the first rib 330, the second rib 340, and the variable part 320 continuously protruding or recessed along the length direction.

Subsequently, the elastic ring 310 is inserted into the variable part 320 on the periphery of the variable part 320.

The elastic ring 310 is formed of a stretchable material and is provided in the form of a tube (TUBE) to move up and down on the variable part 320 and increase in response to an increase or decrease in the diameter of the variable part 320.

In this case, when the elastic ring 310 is moved to a portion having a smaller diameter in the variable part 320, an outer circumference of the elastic ring 310 is formed similarly to an outer circumference of the first rib 330 or the second rib 340. .

When the elastic ring 310 is positioned at the largest diameter portion of the variable part 320, the thickness of the elastic ring 310 is added to the diameter of the variable part 320 to have the largest diameter possible in the protruding part.

The reason why the elastic ring 310 is disposed in the variable part 320 is that the elastic ring 310 is applied when an external force is applied to the projection part in the movement in which the protrusion part is inserted or separated in the vertical direction. ) Is moved to the upper side of the small diameter in the variable portion 320, and when the external force is applied so that the protruding part is separated from the receiving part, the elastic ring 310 is moved to the largest diameter portion in the variable portion 320 It is to prevent the separation between the receiving part and the protruding part tightly.

In such a configuration, a plurality of insertion regions 302 and separation prevention regions 301 may be formed on the protruding part corresponding to the length of the protruding part.

As shown in FIG. 4, it can be seen that the insertion region 302 and the separation prevention region 301 are alternately formed along the longitudinal direction of the protruding part.

This can be produced by double injection molding according to the characteristics of the furniture as the assembly module 300 assembles the furniture.

Herein, the elastic ring 310 may be inserted to correspond to the separation prevention area 301.

The elastic ring 310 is configured to seal the inner circumference of the receiving part and the outer circumference of the protruding part to prevent the protruding part from being separated from the receiving part, and the elastic ring 310 is inserted along the longitudinal direction of the protruding part. The greater the number, the more likely it will be to prevent the projecting part from separating from the receiving part.

In FIG. 5, it can be seen that the assembly module 300 is formed on the bed frame 400 while the bed leg 500 is assembled to the bed frame 400 according to the second embodiment.

In this way, the assembly module 300 prevents the two members from being coupled and separated, so that the assembly module 300 may be used in various assembly fields as well as the chair 1 or the bed.
