Two-way opening and closing door system {DOOR SYSTEM FOR OPENING HINGED DOOR IN BOTH DIRECTIONS}

The present invention relates to a door system that can be opened and closed in both directions, and more particularly, to a two-way door system that is easy to install and use due to a simple structure, and also has excellent operational reliability.

In general, in a conventional door system provided in electronic products such as refrigerators, walls, furniture, and the like, only one side of the door may be opened or closed with respect to the fixed door support. However, such a door that can be opened to only one side brings a lot of restrictions in the design of the building or the arrangement of furniture or electronic products. In other words, in designing a door support such as a wall of a building, furniture, electronics, etc., sufficient space for the door to be rotated must be secured, and this requirement entails many limitations in the design or arrangement of the door support. Will be done.

In order to overcome the problems in the design or arrangement of the door support as described above, several door and door hinge systems have been developed that can open the door on both sides, i.e., left and right sides of the door. For example, US Pat. No. 5,187,836 discloses a door hinge system that allows the door to be opened on both sides thereof.

However, the door hinge system includes a large number of members, such as holders, receiving plates, stop pins and fastening pins, torsion springs, various grooves, etc., and has a relatively complicated structure, which means that the doors on both sides The same is true for other types of door or hinge systems for opening.

The applicant of the present application has proposed a utility model registration No. 300850 for a two-way door system configured to open the door at both sides. Although the utility model of such a pre-registration has the advantage of being structurally simple, it requires a high degree of precision such that the reliability of the operation is greatly reduced even in the minute tolerances generated during machining or assembly. Therefore, a two-way opening and closing door system having a simple structure, which is structurally stable and has improved operation reliability, has been demanded, and thus, the present invention has been completed.

The present invention has a main purpose to provide a simple structure of the two-way opening and closing door system while structurally more stable than the pre-registered utility model, the improved reliability of the operation.
