However, in the conventional frame supporting devices, when the frames are coupled with the support frame, they are simply fitted or screwed together, so that the combined state can not be stably maintained after coupling .

In addition, there is a problem that workability is poor due to inconvenience of connection work.

The present invention has been proposed in order to solve the above-mentioned problems of the prior art. It is an object of the present invention to improve efficiency of operation due to easy separation and assembly, thereby increasing usage efficiency, And to provide a supporting device for a furniture which is capable of maintaining stability.

Detailed descriptions of well-known functions and constructions which may be unnecessarily obscured by the gist of the present invention are omitted.

1 to 7 are views showing a furniture support apparatus according to an embodiment of the present invention. As shown in Fig. 3, the furniture support apparatus 1 according to the present embodiment has a structure in which, And a vertical frame (200) coupled to the horizontal frame (100) and supporting the horizontal frame (100) from the floor, the furniture (10) ) Of the present invention.

That is, they are disposed to be spaced apart from each other between the horizontal frames 100 and the vertical frames 200, which constitute the furniture 10, and thus the durability is improved by increasing the supporting force.

The furniture support apparatus 1 according to the present embodiment includes a support frame 2 disposed between each of the horizontal frames 100 and the vertical frames 200; And connection means (3) for connecting both ends of the support frame (2) to the horizontal frame (100) and the vertical frames (200).

That is, the supporting frame 2 is disposed between the connecting means 3 fixed on the horizontal frame 100 and a part of the vertical frame 200, respectively, to form a supporting force.

In the furniture support apparatus 1 according to this embodiment, the support frame 2 may be a pipe having a length and having both ends penetrated, It is preferable that it is made of a metal material.

In the furniture supporting apparatus 1 according to the present embodiment as described above, the connecting means 3 has a length in the longitudinal direction of the supporting frame 2 at one end, A pair of pressing protrusions 31 disposed symmetrically with respect to the center and spaced from each other at a center thereof and a pair of pressing protrusions 31 disposed at the other end of the pair of horizontal frames 100 and one of the vertical frames 200 A connecting body 34 in which engaging pieces 33 having bolt fastening holes 32 to be fastened to the outer circumferential surface through bolts are arranged and a connecting body 34 which is provided between the pressing protruding portions 31 And a moving member (36) having a moving body (35) in which the pressing protrusions (31) are close to and spaced from each other by applying and releasing pressure in a direction toward the pressing protrusions (31).

That is, in a state in which the pressing protrusions 31 provided in the connecting body 34 are accommodated inside the one end of the supporting frame 2, the moving body 35 of the moving member 36 is linearly moved, The pressing protrusions 31 are prevented from being pressed into the support frame 2 by applying the pressure to separate the protrusions 31 from each other so that the connection means 3 and the support frame 2 are engaged.

The bolts are fastened to the horizontal frame 100 and the vertical frame 200 by bolts through bolt fastening holes 32 formed in the fastening pieces 33 of the fastening body 34, The joining operation of the furniture support apparatus 1 according to the present embodiment is completed when the joining member 34 is coupled to the horizontal frame 100 and the vertical frame 200.
