Abstract

The present invention relates to a door support structure for an upper-open type enclosure, such as a showcase or kimchi refrigerator, in which the door opens upward, which supports the door elastically through a more affordable and simple structure and allows the elastic force to be easily adjusted. The structure includes: an enclosure with an open top; a door connected to one side of the upper surface of the enclosure so as to be openable and closable, with a key coupling hole formed horizontally at the connection point with the enclosure; and a rod-shaped plate spring having a key coupling assembly fixed at one end so as to be inserted horizontally into the key coupling hole for key coupling, and a fixing assembly fixed at the other end so as to be fixed to a first fixing bracket of the enclosure while in a twisted state containing elastic force.

Claims (5)

  1. An open-top casing; A door connected to one side of the upper surface of the above-mentioned housing in a manner that allows it to be opened and closed, with a key coupling hole formed horizontally at the connection portion with the housing; and A rod-shaped plate spring having a key coupling assembly fixed at one end so as to be inserted horizontally into the key coupling hole to form a key coupling, and a fixing assembly fixed at the other end so as to be fixed to the first fixing bracket of the housing while in a twisted state containing elastic force; The above-mentioned fixed assembly comprises a spring fixing piece fixed to the end of the leaf spring to support the position of the leaf spring, a fixed shaft fixed to the center of the spring fixing piece, and a fixed gear fixed to the end of the fixed shaft; A door support structure for an upper open-type enclosure, characterized in that a gear fixing hole is formed at the position corresponding to the fixing gear of the first fixing bracket, the gear fixing hole having the same shape and size as the external shape of the fixing gear, and the fixing gear is twisted to retain elastic force in the leaf spring, and the fixing gear is fitted into and fixed in the gear fixing hole of the first fixing bracket at an external position of the key coupling hole.
  2. In Article 1, The above key coupling assembly is formed with the same cross-sectional shape as the key coupling of the door, so that the key coupling assembly does not rotate separately from the door when the door is opened or closed. A door support structure for an upper open type enclosure, characterized in that a second fixing bracket with a protruding rotation axis is fixed at a position opposite to the first fixing bracket among the door connection parts of the enclosure, and the rotation axis is rotatably fitted and fixed in the key coupling hole.
  3. delete
  4. In Article 2, A first bearing that assists in the opening and closing operation of the door is interposed at the inner position of the key coupling hole between the spring fixing piece of the fixed shaft and the fixed gear, and A door support structure for an upper open-type enclosure, characterized in that a second bearing that assists in the opening and closing operation of the door is interposed at the position inside the key coupling hole of the rotation axis of the second fixed bracket.
  5. In Article 4, A support structure for an upper open-type enclosure, characterized by having a cover fixed to the outer side of the key coupling hole of the door to prevent each bearing from coming out of the key coupling hole.

Description

Door supporting structure of chest with opening top The present invention relates to a door support structure for an upper-open type enclosure, and more specifically, to a door support structure for an upper-open type enclosure, such as a showcase or kimchi refrigerator, in which the door opens upward, which elastically supports the door through a structure that is more affordable and simple, and allows the elastic force to be easily adjusted. Generally, the enclosure with the door opening upward can be configured in various ways, such as a showcase or a kimchi refrigerator, and the door is designed to be easily lifted when a user lifts it, and to close automatically by its own weight when the door is tilted at a certain angle. To this end, a shock absorber is sometimes provided between the door and the main body, but since the shock absorber is exposed to the outside, it is aesthetically unpleasing and gets in the way during use, so recently, a damper is inserted at the hinge connection point between the door and the main body so that it is not exposed to the outside. However, since the elasticity of the damper is determined by its size, the size of the damper must increase as the size of the door increases; however, the hinge connection between the door and the main body that can accommodate the damper cannot increase indefinitely, so for this reason, even if the enclosure becomes larger, the size of the door must be made small. Consequently, even if the enclosure becomes large, the door is relatively small, so the functionality as a showcase or kimchi refrigerator is inevitably reduced. In addition, the elasticity of the damper inevitably deteriorates over time, causing the door to malfunction. Although the damper can be replaced with a new one through repairs, this has the disadvantage of being very cumbersome and incurring unnecessary costs.
