Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] Industrial Field of the Invention The present invention is an exhibition of a cooling showcase provided with an exhibition stand on which goods are placed and which is rotatably held and blows and sucks cold air. The present invention relates to an improvement of a table holding structure.

2. Description of the Related Art As long as a table for holding a product is rotatably held, the product can be taken out from one direction and the product can be taken in and out from any direction by the turning operation. Therefore, various showcases in which the base is rotatably held have been proposed, and examples of those having an opening / closing door include Japanese Utility Model Laid-Open No. 49-85662 and Japanese Utility Model Publication 60.
-41166 is available.

In Japanese Utility Model Publication No. 60-41166, a turntable is rotationally driven by a motor, and only the turntable can be braked and stopped without stopping the motor. On the other hand, Japanese Utility Model Laid-Open No. 49-85662 discloses that a rotating support plate (which is referred to as a turntable in the text) is rotated together with an exhibition room above a showcase. No matter what position is stopped, the suction port and the discharge port formed in the machine room will not be blocked by the turntable,
A hollow hole is formed in the outer peripheral portion of the turntable.

SUMMARY OF THE INVENTION In Japanese Utility Model Publication No. 60-41166, air cooled by a cooler is introduced into an exhibition room by a blower. However, since the exhibition room has a multi-stage structure, it is cool. It is difficult to configure so that the air conditioners can be blown out / sucked in from the turntable itself, and even if it is made into a single stand, it does not present a structure in which cool air can be blown out / sucked in from the stand itself. Further, the turntable is fixed to the outer circumference of a cylindrical body fitted around the rotary shaft so as to be rotatable and slidable in the axial direction by using a mounting member. For this reason, the turntable can be removed from the rotary shaft, but the upper plate of the showcase supporting the upper end of the rotary shaft must be removed, which does not allow easy attachment / detachment work.

On the other hand, in Japanese Utility Model Publication No. 49-85662, the exhibition room itself is rotated at the same time as the turntable is rotated, and the merchandise can be put in and taken out from many directions by rotating the turntable. I do not have it. Also, the shaft at the bottom of the turntable is fitted into the shaft receiving hole in the center of the machine room, so it is not possible to attach / detach only the turntable while leaving the exhibition room as it is.

Therefore, the present invention provides a cooling showcase having a turntable that can be attached / detached independently of an exhibition room, and its object is to facilitate positioning when attaching the turntable. To do.
