Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelf supporting device for storing articles in storage such as commercial refrigerators and freezers.

[0002]

2. Description of the Related Art Conventionally, this type of storage has a storage chamber formed in a heat-insulating box formed by foam-filling a heat insulating material between a box-shaped outer plate and an inner plate that are open to the front. A plurality of shelves for storage are erected. In this case, conventionally, a strut extending vertically is attached to the inner surface of the inner plate, and a structure in which a shelf support for shelf support is locked in a locking hole formed in this strut is used, but the cost of the shelf support is reduced. As a result, the workability of assembling has deteriorated due to the increase in the number of parts.

Therefore, for example, in Japanese Utility Model Laid-Open No. 6-56680 (F25D25 / 02), a plurality of locking holes are vertically formed at predetermined intervals in the inner plate itself, and the rack support is locked in the locking holes. The pillar was deleted by making it.

[0004]

However, in such a structure, the widest surface of the inner plate (hereinafter referred to as the inner plate reference surface).
Since the lock hole and the locking hole exist in the same continuous plane, the load (downward) applied to the shelf locally acts on the locking hole via the shelf holder, which causes the locking hole to deform. When it occurs, the same amount of deformation as this deformation spreads to the inner plate reference surface, so there is a problem that a wide range of deformation of the inner plate and peeling between the inner plate and the heat insulating material are likely to occur. .

This is also the case when an impact other than the shelf load is applied to the inner plate reference surface side. In this case, on the contrary, the deformation of the inner plate reference surface side spreads to the locking hole and locks. It becomes easy to cause deformation of the holes and deviation of the row of holes.

The present invention has been made in order to solve the above-mentioned conventional technical problems, and prevents deformation of the periphery of the locking hole for locking the shelf support while simplifying the structure. Alternatively, it is an object to provide a shelf support device for a storage that can be suppressed.
