A drawer rail and a home appliance including the same are disclosed. The home appliance includes a drawer rail configured to withdraw an item accommodation unit provided in a storage chamber. The drawer rail includes a first rail mounted to the storage chamber, a second rail coupled to the item accommodation unit, a third rail disposed between the first rail and the second rail, a first retainer disposed between the first rail and the third rail to allow relative sliding movement, a second retainer disposed between the second rail and the third rail to allow relative sliding movement, a first stopper for limiting an allowable relative sliding distance between the first rail and the third rail, and a second stopper for limiting an allowable relative sliding distance between the second rail and the third rail.

A low-friction roller assembly is provided. The low-friction roller assembly is especially suitable for use in a refrigerator for reducing noise and reducing wobble and vibration. The low-friction roller assembly has a rotating element encased within a fluid and secured within a housing. An axle attached to the rotating element extends outside of the housing and is connected to a wheel via a keyed interlocking component. The wheel is attached to mount assembly in, for example, a refrigerator, which is attached to a movable drawer.

A slide rail assembly includes a first rail, a second rail, a third rail, and a position-limiting member. The third rail is movably mounted between the first and the second rails. The second and the third rails can be displaced with respect to the first rail from a predetermined position in a first direction. When the second and the third rails are at the predetermined position with respect to the first rail, a first portion of the position-limiting member is adjacent to an end portion of the three rails, and a second portion of the position-limiting member prevents the three rails from separating from one another in a second direction substantially perpendicular to the first direction.

A sliding device is capable of decreasing a moving distance of a middle rail while maintaining a maximum moving distance of a movable rail. The sliding device includes a fixed rail fixed to a body into which a storage body is inserted, the movable rail fixed to the storage body, the middle rail installed between the movable rail and the fixed rail and configured to move relatively with respect to the movable rail and the fixed rail, and a driving part configured to move the middle rail so as to move the movable rail by a distance twice a moving distance of the middle rail.

A wall shelf system having a shelf bracket comprising a rear end for fastening to a wall rail, a front end, and at least one first side wall, and having a guide rail for a shelf element that can be pulled out and comprising a rear end, a front end, and a side wall. Coupling features are provided at the shelf bracket and at the guide rail that correspond to one another and that enable the guide rail to be releasably fastened to the shelf bracket.

A drawer pull-out guide including a first guide rail and a second guide rail displaceably supported relative to one another in a longitudinal direction of the guide rails between a closed position and an open position. A guide body is supported between the guide rails, and the guide rails are guidable relative to one another in a lateral direction in a mounted position of the drawer pull-out guide by the guide body. At least one of the guide rails includes a protrusion bearing against the guide body in the open position of the guide rails, so that at least in that region, in which the guide body and the protrusion bear against each other, the guide rails are arranged without clearance relative to one another in the lateral direction.
