Description

{Bracket For Shelf}

The present invention relates to a bracket for a shelf, and more particularly, to a bracket for a shelf that allows the installation angle of the shelf to be adjusted at various angles as needed.

The shelf is usually installed on the wall, and is one of the storage means that allows various articles to be placed. Shelves can be used for interior and living convenience.

Since the shelf is fixed to the wall by using a regular operator bracket, the shelf is always protruded from the wall regardless of whether or not the article is placed on the wall. If it is protruding until there is no article, it can cause a trouble on walking and also make the space of the room narrow. Therefore, if the shelves can be installed or disassembled as needed, the interior space can be used more advantageously.

For such a problem, Korean Utility Model Application No. 20-2012-0007106, No. 20-2008-0000437 proposes a folding shelf or shelf system. Conventional techniques are mostly proposed for business use, and it is a common practice to select either a folded state or a 90 degree extended state. The structure of the folded part of the bracket is complicated.
