The rack support

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a shelf support for supporting a shelf from the bottom, and more particularly, to a shelf support for supporting a shelf in a cantilever shape using a cantilever.

FIG. 1 is a perspective view showing a conventional structure of a shelf support to which the present invention belongs, and FIG. 2 is a perspective view for explaining a problem of a conventional shelf support. 1, a bracket 20 for supporting the shelf 50 from the lower side is installed in a multi-stage structure in a vertical frame 10 fixed to a wall surface, and a plurality of brackets 20 , The shelf 50 is completed by putting the shelf 50 on the upper part of the shelf 50 through the piece 12. The conventional problem is that the bracket 20 is installed on the vertical frame 10 and the pressing force generated in the process of screwing the plate press fitting 22 and the bracket 20 together through the piece 12 The bracket 20 is supported on the front surface of the vertical frame 10. When a heavy object is placed on the shelf 50 as the shelf 50 is seated on the upper surface of the bracket 20 having the above-described assembling structure, a load is concentrated on the portion where the vertical frame 10 and the bracket 20 are in contact with each other The supporting force of the bracket 20 is lost and the balance of the shelf 50 collapses.

Accordingly, it is an object of the present invention to provide a cantilever system capable of not only dispersing a concentrated load to a portion where a vertical frame and a bracket are in contact with each other, but also reliably receiving a concentrated load, We propose a shelf bracket with a compression sphere as a medium.

A bracket 20 is disposed on the front surface of the vertical frame 10 and a cantilevered pressing fitting 30 is inserted into the first fitting groove 11 of the vertical frame 10 The cantilever pressing tool 30 includes a vertical part 31 fitted in the first fitting groove 11 and a vertical part 31 connected to the vertical part 31, And a through hole 33 is formed in a portion where the vertical portion 31 and the horizontal portion 32 meet and are bent at a right angle, The fitting protrusion 21 protruding from the back surface of the bracket 20 is screwed to the vertical portion 31 of the cantilever pressing fitting 30 and the piece 12, The pressing member 41 is positioned between the horizontal part 32 of the cantilever pressing part 30 installed at a constant spacing distance H and the upper surface of the bracket 20, The upper surface and the horizontal part 32 supporting the frame 40. As the pressing force applied to the cantilever crimping opening (30) of the brackets (20) is configured to be coupled.

When the shelf support according to the present invention is used, it is possible to firmly support the load concentrated on the portion where the vertical frame and the bracket are brought into contact with each other through the cantilever press fitting, so that a stable shelf can be installed.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

FIG. 1 is a perspective view of a conventional shelf support, and FIG. 2 is a perspective view illustrating a conventional shelf support. 1, the vertical frame 10 and the bracket 20 are connected to each other through a flat-plate-pressing part 22 (see FIG. 1). The shelf 50 is a multi-layered structure for displaying and arranging objects. Is shown.

2, the bracket 20 for supporting the shelf 50 at the bottom is provided with a fitting projection 11 protruding from the rear surface of the bracket 20 in a first fitting groove 11 formed along the longitudinal direction of the vertical frame 10, A flat plate crimping tool 22 inserted into the first fitting groove 11 of the vertical frame 10 and a fitting protrusion 21 of the bracket 20 are inserted into the fitting groove 21, The bracket 20 is fixed to the front surface of the vertical frame 10 by screwing the bracket 20 to the front surface of the vertical frame 10 as an intermediary. 2, due to the pressing force generated in the process of screwing the plate presser 22 and the bracket 20 together through the pieces 12, the bracket 20 is attached to the front surface of the vertical frame 10, 20) is located.

However, the structure of the conventional shelf bracket as described above is insufficient to support heavy objects. This is because the load of the heavy object is concentrated at a portion where the vertical frame 10 and the bracket 20 are in contact with each other, thereby the supporting force of the bracket 20 is lost.

3 is an exploded perspective view of the shelf support according to the present invention. As described above, the structure of the cantilever pressing member 30 for solving the problem that the bearing force of the bracket 20 is weakened due to the local concentration of load is shown in FIG. It is. 3, the cantilever pressing tool 30 includes a vertical part 31 fitted in the first fitting groove 11 of the vertical frame 10 and a vertical part 31 connected to the vertical part 31, And a horizontal portion 32 bent at a right angle and positioned on the upper surface of the bracket 20 with a constant height H therebetween. In the process of fitting the cantilevered pressing part 30 into the first fitting groove 11 of the vertical frame 10 at a portion where the vertical part 31 and the horizontal part 32 meet and are bent at right angles, The through-hole 33 is formed so as not to be generated.

The vertical part 31 of the cantilever pressing part 30 is inserted into the first fitting groove 11 of the vertical frame 10 and the bracket 20 is inserted into the cantilevered pressing part 30 by using the piece 12, The bracket 20 is positioned on the front surface of the vertical frame 10 while the pressing force is generated between the vertical frame 10 and the bracket 20. [ 3 is screwed into the horizontal part 32 of the cantilever pressing part 30 so that the second fitting groove 41 formed along the longitudinal direction of the supporting frame 40 By pressing the top surface of the bracket 20 and the horizontal portion 32 of the cantilevered press fitting 30 by using the piece 12 after the cantilever pressing member 30 is inserted into the horizontal portion 32 of the cantilever pressing member 30, (40) is firmly positioned on the upper surface of the bracket (20).

Hereinafter, the mounting procedure of the shelf support according to the present invention, which can firmly support the load of heavy objects placed on the shelf 50, will be described with reference to FIGS. 4 and 5 are flowcharts for explaining the mounting of the shelf support according to the present invention. 4 (a), when the vertical part 31 of the cantilever pressing part 30 is inserted into the first fitting groove 11 of the vertical frame 10, as shown in FIG. 4 (b), the cantilever pressing part 30 are assembled so as to move along the first fitting grooves 11 of the vertical frame 10 and the bracket 20 is assembled in accordance with the mounting position of the shelf 50. As shown in Figure 4 (c) When the vertical portion 31 of the pressing tool 30 and the bracket 20 are screwed together using the pieces 12, a pressing force is generated between the vertical frame 10 and the bracket 20, And is positioned on the front surface of the frame 10.

5 (a), when the bracket 20 is assembled, the horizontal portion 32 of the cantilevered pressing tool 30 is positioned on the upper surface of the bracket 20. As shown in FIG. 5 (b), the support frame 40 is assembled to the horizontal portion 32 of the cantilevered press fitting 30. The upper surface of the bracket 20 and the cantilevered portion The second fitting groove 41 of the receiving frame 40 is inserted into the upper surface of the bracket 20 and the cantilevered pressing fitting 30 as the horizontal portion 32 of the sphere 30 is positioned at a constant spacing height H. [ And the horizontal portion 32 of the main body 32. As shown in Fig. 5 (c), when the upper surface of the bracket 20 and the horizontal portion 32 of the cantilevered press fitting 30 are subjected to a pressing force by using the piece 12, As shown in Fig.
