Abstract

The present invention relates to a hinge device of a swing door, and is mainly installed in the front of a show case displaying refrigerated foods such as a department store or a supermarket. In the lower hinge device for supporting a glass door, the lower end of the pivot is positioned around the central axis. The locking jaw and the moving inclined surface were formed to face each other back and forth. In addition, the pivot holder fixed to the door frame is a cylindrical guide which is formed with the vertical surface and the guide inclined surface and the stop groove recessed in the middle portion of the guide inclined on the front and back to be fixed to each other. Rotational movement within the stop once at a right angle position by the locking jaw and the stop groove, and closed to automatically return to the original position by the weight of the door. Therefore, there is no need for a separate device for returning the rotated door, the structure is simple, and there is little concern of failure, and the energy can be saved by keeping the inside of the refrigerated showcase warm.

Description

Hinge device of swing door {HINGE SYSTEM FOR HINGED DOOR}

The present invention mainly relates to a hinge device of the swing door installed in the front of the show case to display refrigerated food, such as department stores or supermarkets. More specifically, in the lower hinge device for supporting the glass door, a cylindrical pivot is integrally formed on the support, and the lower end of the pivot is formed to face the front and rear moving slanted upwardly from the locking step and the locking step. It became. In addition, the pivot holder fixed to the door frame is a cylindrical guide which is formed with the vertical surface and the guide inclined surface and the stop groove recessed in the middle portion of the guide inclined on the front and back to be fixed to each other. Rotational movement within the stop once at a right angle position by the locking jaw and the stop groove, and closed to automatically return to the original position by the weight of the door. Therefore, there is no need for a separate device for returning the rotated door, the structure is simple, and there is little worry of failure, and it is possible to save energy by keeping the inside of the refrigerated showcase warm.

Refrigerated food showcases in large stores are typically open to the front to make it easier for consumers to choose what they want. However, in order to keep the freshness of the product for a long time and to save energy by blocking the inside of the show case from the outside, it is desirable to install a glass door on the front. However, if the support of the glass door is framed, the part covering the field of view is so wide that it is not easy to express all the goods inside, and also the problem of having to stop once the door is opened and the door automatically return to its original position. The device was complicated and there were many drawbacks of fixation. Therefore, the situation is required to improve the visibility by simply installing the glass door of the refrigerated showcase, to open smoothly and stop once and close automatically.

The present invention has been devised in view of the above-mentioned conventional problems, and when the glass door is pulled forward, the moving slope of the pivot in the hinge device is rotated along the guide slope of the guide, and once the door is opened at a right angle, it stops. After selecting the product, it is automatically rotated to return to the original position by pushing the door inwards slightly. It is easy to install the glass door in the refrigerated showcase, and it improves the visibility by widening the viewing area, and smooth opening and stopping and automatic Its purpose is to provide a hinged device for the swinging door to be closed by the door.

In the present invention, in order to solve the above problems, as an improved design for the lower hinge device of the glass door, the moving inclined surface inclined upwardly from the lower end of the vertical plane and the lower end of the vertical plane to the periphery of the lower central axis of the cylindrical pivot In the pivot holder fixed to the lower door frame, a cylindrical guide having a vertical surface and a guide inclined surface and a stop groove recessed in the middle of the guide inclined surface is fixed to the upper surface so that the vertical plane and the moving inclined surface of the pivot are perpendicular to the vertical surface of the guide. The occlusal surface was constructed. When the glass door is pulled forward and the angle is in a right angle, the locking jaw of the pivot rotates upward along the guide inclined plane of the guide and stops seating in the stop groove, and when the door is closed again, the door is slightly pushed inward to lock the pivot. When the jaw is out of the stop groove of the guide, the moving slope is automatically rotated downward along the guide slope by the weight of the glass door to return the glass door to its original position.

This design is very easy to install on the glass door on the showcase, widen the viewing area of the glass door to facilitate the display of goods displayed on the cold showcase, the smooth opening of the glass door and the effect of stopping and closing automatically once have. It is also a useful design that has the advantage of saving energy by acting to keep the internal temperature of the refrigerated showcase warm.

Referring to the configuration and operation of the subject innovation in detail as follows.

1 is an installation state diagram of the present invention, the support (10, 20) is fixed to the upper and lower corners of the glass door 30, pivot (11), which is formed opposite to the support (10), (20) 21 is opposed to the pivot holders 60 and 70 provided on the upper and lower door frames 40 and 50. Reference numeral 31 denotes a handle.

FIG. 2 is an enlarged view in which the “a” part of FIG. 1 is separated, which is a lower hinge device of the glass door, and is perpendicular to the circumference of the lower center axis 22 of the pivot 21 downwardly formed on the support 20. And the moving inclined surface 25 inclined upwardly from the lower locking jaw 24 of the vertical surface 23 and the back and forth, and the pivot holder 70 fixed to the door frame 50 has a vertical surface 81 and a guide inclined surface on the upper surface. (82) and the cylindrical guide (80) formed with the stop groove 83 recessed in the middle portion of the guide inclined surface 82 back and forth is inserted, the fixing projections 71 protruding on the inner peripheral surface of the pivot holder 70 It is inserted into the fixing groove 84 of the guide 80 to fix the guide 80 is not rotated. Reference numeral 90 denotes a bolt for fixing the glass door 30 to the support 20.

3 is a side view of the coupling state of Figure 2, Figure 4 is a side view of the portion of the pivot is engaged with the guide of the present invention in Figure 3, the vertical surface 23 and the moving inclined surface 25 of the pivot 21 respectively guide Engages with the vertical surface 81 and the guide inclined surface 82 of the sphere (80).

5 is an operation state diagram of the present invention, when the handle 31 of the glass door 30 is pulled forward and the moving inclined surface 25 of the pivot 21 is rotated upward along the guide inclined surface 82 of the guide 80 When the glass door 30 is opened at a right angle, the locking jaw 24 of the pivot 21 is seated in the stop groove 83 of the guide 80 so that the glass door 30 is once stopped. When the glass door 30 is closed again, the glass door 30 is pushed inwards slightly so that the locking jaw 24 of the pivot 21 is out of the stop groove 83 of the guide 80. By this, the moving inclined surface 25 of the pivot 21 is automatically rotated downward along the guide inclined surface 82 of the guide 80 to return to its original position.
