Hereinafter, a hinge bracket for a folding leg according to the present invention will be described with reference to the accompanying drawings.

As shown in Figs. 1 to 5, the folding leg hinge bracket according to the present invention is attached to a folding leg 40 that is foldably installed on the lower side of the table 60, and is fixed to the bottom surface of the table 60 A body 10 rotatably coupled to the bracket 50 and attached to the upper end of the folding leg 40 and rotatably coupled to the fixing bracket 50; And an elastic body 20 which is fixed to one side of the main body 10 so as to maintain the folded leg 40 in a folded state or an unfolded state by using an elastic force and has an inner hollow space for elastic force.

The main body 10 includes a horizontal portion 11 which is in close contact with an upper surface of a folding leg, a side portion 12 which is in close contact with a side surface of the folding leg 40, And an inclined portion 13 connecting the portion 11 and the side surface portion 12 and having the hinge insertion hole 14 formed therein. The elastic body 20 has a fixing part 21 for positioning the folded leg 40 in a state where the convex surface end of the elastic body 20 is positioned on an extension of the horizontal part 11, (22) for preventing the folding leg (40) from being unfolded, the end of the convex surface being positioned on an extension of the side portion (12) A pressing portion 24 for concavely connecting the side surface portion 12 and the unfolding prevention portion 22 and a pressing portion 24 for connecting the fixing portion 21 and the unfolding prevention portion 22, And an inclined connection portion (25) disposed in parallel with the first connection portion (13).

The elastic body 20 may further include a rib 26 connecting the inside of the fixing portion 21 and the inclined portion 13 of the main body 10. The main body 10 and the elastic body 20 are preferably formed of a synthetic resin material and integrally injection-molded.

The rotating bracket for a folding leg constructed as described above is mounted on a folding leg and is coupled to a fixing bracket provided on the lower side of the table so that the folding leg is opened or folded.

A through hole 11 'formed in the horizontal portion 11 of the main body 10 and a side wall portion 12' formed in the horizontal portion 11 of the main body 10, after the rotation bracket in which the elastic body 20 and the main body 10 are integrally formed, The main body 10 is fixed to the folding leg 40 by means of a fixing means such as a screw inserted into the through hole 12 ' At this time, since the horizontal part 11, the side part 12, and the inclined part 13 of the main body 10 are fixed in a state of being in contact with the folding legs 40, As shown in Fig.

A rotary bracket is inserted into a fixing bracket 50 fixed to a lower portion of the table 60 and a screw hinge is inserted into a hinge insertion hole 14 formed in an inclined portion 13 of the main body 10, The assembly of the folding legs 40 is completed by rotatably engaging with the fixing bracket 50.

When the folding leg 40 is folded, as shown in FIG. 4, the outer side surface of the side surface portion 12 of the main body 10 and the spread preventing portion 22 of the elastic body 20 are brought into contact with the fixing bracket 50. When the rotation bracket is supported by the fixing bracket 50 in a two-point contact manner, the folding legs 40 are not unfolded and fixed so long as no external force is applied to the deformation preventing portion 22 State. Therefore, when the table 60 is transported with the folding legs 40 folded, the folding legs 40 are prevented from wobbling or the folding legs 40 are suddenly unfolded. As a result, It is possible to prevent safety accidents that may occur.

When the table 60 is moved to the use position, the folding leg 40 may be unfolded by holding the lower end of the folding leg 40 and rotating it. In this case, when the folding leg 40 is rotated, a sufficient external force is applied to the unwinding preventing portion 22, so that even if no external force is applied, the spreading preventing portion 22 is deformed to some extent, Thereby releasing the fixation. Therefore, the folding leg 40 can be rotated and opened naturally.

The outer side of the horizontal portion 11 of the main body 10 and the fixing portion 21 of the elastic body 20 are brought into contact with the fixing bracket 50 as shown in FIG. 5 when the folding leg 40 is unfolded, Is supported on the fixing bracket 50 in a two-point contact manner, whereby the folding legs 40 are fixed so as not to be folded. The folding leg 40 is kept in the unfolded state unless the external force enough to deform the fixing portion 40 is applied to the elastic body 20 and the folding leg 40 is held by the folding leg 40, Is firmly supported and is not shaken.

When the folding leg 40 is folded after the use of the table 60 is completed, an external force enough to deform the fixing portion 21 may be applied to the elastic body 20 so as to be folded. That is, when the pressing part 24 of the elastic body 20 is pressed, the fixing part 21 is deformed and heard so that the folding leg 40 can be rotated. In this state, the folding leg 40 may be folded by rotating it in the direction of the side surface 12 of the main body 10.

Although the elastic body 20 is formed of synthetic resin having the same material as that of the main body 10, the elastic body 20 may be formed of a metal plate having the same shape to form the metal elastic body 20 '. 6, the metal elastic body 20 'is fixed to the main body 10 by fitting both ends of the metal elastic body 20' into the inclined portion 13 of the main body 10 . However, in this case, since the metal elastic body 20 'has a sufficient rigidity, it is not necessary to provide the ribs separately as in the case of the synthetic resin elastic body.
