用于门的开闭单元
摘要：
本发明提供了一种用于诸如冰箱的家庭酒吧门之类的门的开闭单元。该开闭单元包括可旋转地设置在框架(100)中并且连接到扭力弹簧的转盘(200)。对设置在门上的钩子可释放地锁定的钩接合件(201)形成在转盘中。在转盘的一个表面上形成有运动路径(210)，使得转盘的两次旋转形成一次循环。所述框架在面向转盘的运动路径的位置处具有导向槽(110)。所述开闭单元还包括设置在由导向槽和运动路径限定的空间中的球(300)。因此，根据本发明的开闭单元可以利用沿着在转盘中形成的运动路径运动的球而重复地进行门的开闭操作。
摘要（英）：

The present invention provides an open and close unit for a door, such as a home-bar door of a refrigerator. The open and close unit includes a rotating disk (200) which is rotatably provided in a frame (100) and is connected to a torsion spring. A hook catch (201) which releasably locks a hook provided on the door is formed in the rotating disk. A moving path (210) is formed in one surface of the rotating disk such that two rotations of the rotating disk form one cycle. The frame has a guide groove (110) at a position facing the moving path of the rotating disk. The open and close unit further includes a ball (300) which is provided in a space defined by the guide groove and the moving path. Thereby, the open and close unit according to the present invention can re not peatedly conduct an operation of opening and closing the door using the ball which moves along the moving path formed in a rotating disk.
