Patent ID: 8632142

Claim:
An undermount-type sliding apparatus, comprising: a movable rail provided under a receptacle; a fixed rail slidably coupled to the movable rail such that the movable rail is operable to be opened and closed; and an automatic closing device comprising: a housing body disposed on one side of the fixed rail, the housing body having a housing space having an open upper portion and a lower portion; a guide wall comprising: a curved guide portion partially protruding from one side to the other side in an open interior of the housing body, the curved guide portion extending from a lower end toward a central portion so as to have a curved shape and being spaced apart from one end of the housing space in an opening direction; and a linear guide portion connected to the curved guide portion, the linear guide portion extending in a closing direction to have a linear shape in a central portion of the housing space; a rotary stopper positioned so as to be inserted into and guided by the guide wall while being caught by and released from the movable rail; and an elastic member disposed in the housing body in the closing direction, the elastic member being elastically coupled to the rotary stopper; wherein, in a closing operation of the movable rail, the rotary stopper is operable to catch the elastic member so that the rotary stopper is automatically closed by elasticity of elastic force, and when the rotary stopper is positioned in the opening direction, the opening direction of the rotary stopper moves downward along the curved guide portion in a state in which the elastic member stays in a stretched state, so that the movable rail is released from the rotary stopper to enable an opening operation; and wherein the housing body has a through-hole, the linear guide is elastically deformable by an external force, and the through-hole is positioned in a way that, when a downward external force applies to the rotary stopper, the linear guide portion descends through the through-hole of the housing body by elastic deformation.
