A slide rail assembly includes a first rail, a second rail, a third rail and a switch member. The second rail is movably mounted between the first rail and the third rail. The switch member is linearly movable and configured to be switched between a first state and a second state. When the switch member is in the second state, the second rail is configured to be driven by the third rail to move to a predetermined position along a retracting direction. When the third rail is moved relative to the second rail at the predetermined position along an extending direction, the switch member is configured to be switched from the second state to the first state.

A slide rail assembly includes a first rail, a second rail displaceable with respect to the first rail, a third rail displaceable with respect to the second rail, a working member movably mounted on the second rail and switchable between two states, and a contact feature on the third rail. The third rail can be displaced from a retracted position to an extended position in a first direction, and when the third rail is displaced from the extended position to the retracted position in a second direction, the contact feature is brought into contact with the working member in one of the two states so as to drive and thereby retract the second rail with respect to the first rail in the second direction.

A three-section linkage drawer slides apparatus, includes an upper rail, a middle rail, a fixed rail, an upper linkage rack, and a lower linkage rack, wherein the middle rail is slidably connected to the fixed rail through the lower linkage rack, the upper rail is slidably connected to the middle rail through the upper linkage rack, the upper linkage rack and the lower linkage rack are of separate structures, the upper linkage rack is mounted between the middle rail and the upper rail after being assembled, and the lower linkage rack is mounted between the fixed rail and the middle rail after being assembled. The upper linkage rack and the lower linkage rack are configured as separate structures, the manufacturing process can thus be simplified, so the manufacturing cost is reduced.

A three-section synchronous slide rail, which has simple structure, longer service life, is easy to install and replace is provided, which includes: two sets of slide rail assemblies which comprise a fixed rail, a middle rail and a sliding rail, synchronization components comprising a flexible deflector unit and a roller, the flexible deflector unit is connected with the fixed rail and the sliding rail, the middle rail is connected with a rope base, a first end of the flexible deflector unit is wound around a first end of the rope base and fixed to the rope base, and a second end of the flexible deflector unit bypasses the roller and is reversely wound on a second end of the rope base and the second end of the flexible deflector unit is fixed to the rope base, a connecting rod is connected between the rope bases.

Slides provided herein may be configured to support substantial loads while experiencing vibration and shock in the retracted position without degradation of the slide mechanism. An example slide may include: a fixed rail member; a second rail member, a third rail member, where the second rail member is disposed between the fixed rail member and the third rail member, where the second and third rail members translate between an extended position relative to the fixed rail member and a retracted position relative to the fixed rail member; and at least one bearing attached to one of the second rail member or the third rail member, where the at least one bearing is engaged when the second rail member is in the extended position, and disengaged in response to the third rail member being in the retracted position.

A drawer slide having first and second rails interconnected by a center rail. The center rail includes a spool configured to provide half-speed travel of the center rail relative to the travel of the first rail. The drawer slide is configured for use with a drawer assembly having a drawer and a chassis. The drawer assembly further includes a radius limiter secured to the center rail. The radius limiter travels at half-speed relative to the drawer. The radius limiter also automatically rotates relative to the travel of the drawer. The chassis includes sides including threaded backing plates, and mounting brackets. The mounting brackets include tri-lobed holes for receipt of a reciprocally shaped washer and a fastener for mounting the brackets to the chassis sides.

The present invention shows a telescopic rail having at least one inner, middle, and outer rail element, wherein the inner and outer rail elements are each longitudinally displaceably supported at the middle rail element over rolling members that are guided in a rolling member cage. Provision is made in accordance with a first aspect that the rail elements are mechanically force-coupled via a rail synchronization arrangement such that on a longitudinal displacement of the outer rail element with respect to the inner rail element, the middle rail element is longitudinally displaced with respect to both the inner rail element and the outer rail element. Provision is made in accordance with a second aspect that at least one rolling member cage, and preferably both rolling member cages, is/are mechanically force-coupled to at least one of the rail elements via a respective rolling member cage synchronization arrangement such that a longitudinal displacement of the middle rail element with respect to the inner or outer rail elements results in a longitudinal displacement of the corresponding rolling member cage with respect to the middle rail element.
