Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a side plate attachment device for a show case.

(b) Prior art Publication No. 61-6823 (A47F3/00) discloses that a pair of left and right support legs each having an opening are attached to the bottom of both sides of a case body having an opening in the front. In a side plate attachment device for a show case in which side plates are attached to both sides of the show case main body, a first U-shaped part consisting of an inner wall and an upper wall and having openings formed on both sides and downward, the vertical wall and the vertical wall. A second wall comprising a bottom wall extending outward from the lower end and a rising wall extending upward from the outer tip of the bottom wall, with openings formed on both sides and above.
The first U-shaped part of the support bracket is hung over the lower edge of the opening formed in the support leg, and the second U-shaped part is hung on the lower edge of the opening formed in the support leg.
A side plate attachment device for a show case is shown in which the lower end of the side plate is inserted into the character-shaped portion from above and the lower part of the side plate is fixed to the support leg.

(C) Problems to be Solved by the Invention According to the above-mentioned conventional technology, when the side plate is placed on the support metal fittings when fixing the side plate, the entire load of the side plate is applied to the support metal fittings. At the same time, since a force is applied to the upper end of the side plate that causes it to move laterally away from the upper end of the side surface of the case body, that is, a rotational force is applied to the upper end of the side plate. Not only does it dig into the top corner of the rising wall, causing problems such as peeling off the paint on the outer wall in contact with the top corner or forming dents on the outer wall, but also the problem that the top of the side plate and the top of the case body are It became necessary to prepare a step stool in order to connect with the L-shaped metal fittings, and there was also the problem that it took time and effort to attach the side plates.

(d) Means for Solving the Problems In order to solve the above problems, the present invention provides a heat insulating wall with openings formed in the front for storing and taking out products;
