A sliding element guide system for furniture is provided, including a cabinet unit rail, central rail, sliding element rail, and at least one carriage. The cabinet unit rail, central rail, and sliding element rail are mounted to be movable in relation to one another. The system also includes two identical synchronization wheels that synchronize movements of elements of the system. The two identical synchronization wheels are rotatably mounted on a vertically oriented central rail side wall and extend horizontally therefrom via a pin.

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.

A slide rail assembly includes a first rail, a second rail, a stop, and a working member. The second rail can be displaced with respect to the first rail. The stop is disposed on the first rail. The working member is movably mounted on the second rail. When reaching a predetermined position after being displaced with respect to the first rail from an extended position in a retracting direction, the second rail is blocked by the stop via the working member and is thus prevented from being displaced from the predetermined position in an opening direction. The slide rail assembly has a shorter length when the second rail is at the predetermined position than when the second rail is at the extended position.

Disclosed herein is a refrigerator. The refrigerator includes a body having a storage compartment therein, a storage body provided to be inserted into or withdrawn from the storage compartment, and a rail device configured to connect the body and the storage body slidingly and to guide insertion and withdrawal of the storage body, wherein the rail device includes a first rail member having a first guider therein, a second rail member slidingly coupled to the first rail member, and a first retainer disposed at an insertion position between the first rail member and the second rail member when the first rail member is inserted into the first retainer and having a first guide protrusion inserted into the first guider movably, formed in the first retainer, and the first guider limits a range of movement in an insertion direction of the first retainer when the first retainer is inserted into the first guider so that the first retainer is located at the insertion position.

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.
