Installation structure of swing door type close showcase and its door automatic closing hinge device {CLOSE TYPE SHOWCASE WITH SWING DOOR AND ASSEMBLING STRUCTURE OF DOOR AUTO-CLOSURE HINGE APPARATUS THEREOF}

The present invention relates to a swing door type closed showcase and an installation structure of its automatic door closing hinge device. More specifically, in the swing door type closed showcase, the cylinder member of the door automatic closing hinge device is not embedded in the frame of the swing door, A swing door-type closed showcase and its automatic door that are installed on the lower body to minimize the width of the frame, minimizing the phenomenon of products displayed in the product display storage room being obscured by the frame and securing the widest possible field of view for consumers. This relates to the installation structure of the closing hinge device.

In general, showcases are used to store and sell products on display in department stores, large discount stores, convenience stores, and supermarkets. They allow buyers to easily select products and directly feel the freshness of the products when purchasing them. It is used to increase buyers' motivation to purchase a product.

Showcases are classified into open showcases, where products are always displayed in an open state, and closed showcases, which are configured to open and close the door, and each is equipped with a refrigeration cycle device inside.

In the conventional swing door type closed showcase, a machine room constituting a cold air generating device is formed in the lower part of the main body, and a product display storage room for displaying products is formed in the upper part of the main body. Cold air is supplied to the product display storage room to keep the inside of the product display storage room cool. Additionally, several shelves are installed in layers and tilted inside the product display storage room so that canned drinks, etc. are displayed on the shelves and stored in a cold state. do.

Additionally, a swing door is attached to the front of the main body to open and close the product display storage room. A swing door consists of glass and a square frame that supports the glass, and a handle is installed on the swing door for opening and closing.

It is important to keep the inside of the product display storage room cool, and to achieve this, it is necessary to prevent cold air from leaking to the outside as much as possible.

Since the swing door is where the cold air from the product display storage room leaks to the outside the most, the installation structure of the swing door that opens and closes the product display storage room is the product display storage room (R). It should be configured to minimize leakage of internal cold air to the outside.

In a conventional swing door-type closed showcase, the swing door is opened, the products to be displayed and sold are displayed in the product display storage room, and the swing door is closed to display and store the products. Consumers open the swing door and select the product they want. So I take it out and buy it.

When a consumer takes out a product displayed and stored in the product display storage room, he or she opens the swing door a certain width with one hand to take out the product, takes out the product with the other hand, and then closes the swing door, and also places the product in the product display storage room. When displaying, fully open and secure the swing door and then display the product in the product display storage room.

The swing door is configured to close automatically when the swing door is left open in order to minimize the leakage of cold air from the product display storage room to the outside. The conventional swing door type close showcase not only guides the opening and closing of the swing door, but also In order to automatically close the swing door if left open, an automatic door hinge device is provided.

Since the conventional door automatic closing hinge device is installed embedded in the frame of the swing door, the width of the frame of the swing door becomes larger and the width of the glass becomes relatively smaller, which causes the frame to obscure some of the displayed and stored products, resulting in consumers There is a problem that causes discomfort to the eyesight of the user.
