Refrigerator rail assembly and refrigerator storage container drawer / drawer device with same

摘要

A refrigerator rail assembly (30, 130) for guiding a storage container while withdrawing or retracting the storage container from a space of a refrigerator, comprising: - a guide rail (32, 132) provided on one side of the storage space to engage in Extending forward-backward direction of the storage space, the guide rail (32, 132) having a guide channel (132c) formed in the longitudinal direction of the guide rail (32, 132) and opening to a side thereof; - a movable rail (46, 146) having a guide channel (146c) formed in the longitudinal direction of the movable rail (46, 146) and opening to a side opposite to the guide channel (132c) of the guide rail (32, 132) wherein the storage container is removably attached to the movable rail (46, 146); - an intermediate rail (44, 144) having a pair of guide flanges (144f) which are despatched a plurality of ball bearings (B) inserted between the guide channels (132c, 146c) and the guide flanges (144f), the guide rails (32, 132) and the movable rail (14) being engaged in the guide channels (146c); 46, 146) move with respect to the intermediate rail (44, 144), whereby the storage container is pulled out of or retracted from the storage space, - a damping unit (34, 134) comprising a piston, a rod connected to the piston ( 37), a damping fluid and an elastic member, and which provides a damping force for reducing the moving speed of the movable rail (46, 146) with respect to the guide rail (32, 132), - a cooperating cam (38, 138) connected to the piston of the Damping unit (34, 134) is engaged and which is formed of a resilient material so that it is elastically deformable in relation to the rod (37), - a guide member (40, 140) provided on the guide rail (32, 132), the guide member (40, 140) having a first guide slot (40a, 140a) for guiding movement of the cooperating cam (38, 138); and - a cooperating member (48, 148) provided on one side of said movable rail (46, 146), said cooperating member (48, 148) being selectively engageable with said cooperating cam (38, 138) in response to the travel distance of the movable rail (46, 146) relative to the guide rail (32, 132).
