OPEN-CLOSING APPARATUS OF HOMEBER DOOR

摘要

An opening/closing device for a home bar door is provided to control a home bar door to be lowered slowly by a predetermined angle when opening the home bar door, thereby reducing shock or damage caused by the lowering of the home bar door. An opening/closing device for a home bar door includes a hinge unit inserted into the home bar door for securing rotation of the home bar door. The hinge unit includes a hollow housing(20), a side of which is opened and the other side is formed with fixing protrusions, wherein the housing is secured on a supporting plate(24). A rotation shaft(30) is inserted into the housing and formed with a rotation control part for controlling rotation of the home bar door by interference of the fixing protrusions with a peripheral part with reference to a plurality of holding protrusions(31), which are formed on an outer peripheral surface in the center of the rotation shaft. A housing cover(40) is in the shape of ring to insert the rotation shaft and detachably mounted to the opened side of the housing, wherein the housing cover controls rotation speed of the rotation shaft by controlling a torque value according to fastening. A fixed shaft(50) is inserted into a shaft coupling groove(32) in the rotation shaft and coupled with an opened side of a refrigerator door.
