Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an assembly shelf that can be assembled without using screws.
[0002]
[Prior art]
This type of conventional assembly shelf is a self-supporting structure in which the upper and lower ends of four struts made of L-shaped angle members are connected by horizontal members called braces or beams. And the shelf is supported by this structure.
Here, the brace is horizontally mounted in the depth direction to connect the columns, and the beam is horizontally mounted in the horizontal direction to connect the columns. Each of these comprises a main body straddling between the support columns and a hanging portion that is integrally suspended from both ends thereof, and has a generally downward U-shape.
[0003]
Then, the inner surface of the support and the hanging portion are engaged with each other by using engaging portions provided at least at two or more places in the upper and lower portions, thereby being connected to each other.
The use of such braces and beams is intended to be assembled without using screws, so the vertical part has a certain length in the vertical direction. This is because they are firmly connected to each other through braces or the like, and the support is made to stand up to form a robust structure. On the other hand, it is considered that if the columns are connected by a shelf plate having a thickness only in the vertical direction, the structure does not use screws, so that it cannot be firmly fixed and becomes unstable.
[0004]
[Problems to be solved by the invention]
However, such braces and beams cause an increase in the number of parts, resulting in a decrease in assembling or disassembling properties and a disadvantage in cost.
[0005]
[Means for Solving the Problems]
In view of such problems, the present invention can reduce the number of parts and simplify assembly by combining the roles of braces and beams with the shelf board in an assembly shelf that can be assembled without using screws. This is to achieve cost reduction.
[0006]
