In order to solve these problems, Korean Patent Registration No. 10-2164925 (hereinafter referred to as 'Patent Document 5') and Korean Patent Registration No. 10-2291943 (hereinafter referred to as 'Patent Document 6') have been proposed. there is.

However, in the case of Patent Documents 5 and 6, it was excellent in bonding force and left and right shaking during coupling, but in order to combine the horizontal member with the vertical member during coupling, a hammer had to be used, and moreover, the horizontal member to install the shelf in a different location In the case of removing the , it is difficult to attach and detach, and even after desorption, damage to the coupling part is frequent, which exposes the problem of weakening the bonding force when re-coupling.

Moreover, in the case of the above-mentioned patent documents, there was a problem that the appearance was not beautiful because the hole of the vertical member was exposed to the outside. There were problems such as possible.

Meanwhile, various types of angles have been proposed to solve the above problems.

That is, Republic of Korea Patent Registration No. 10-2164925 (hereinafter, referred to as 'Patent Document 7') solves the above problems by preventing the fitting groove provided in the vertical frame from being exposed to the outside.
