A slide rail assembly includes a first rail, a second rail, a locking member, a driving member and an operating member. The second rail is movable relative to the first rail. The locking member is configured to lock the second rail relative to the first rail at a predetermined position. The driving member is movable relative to the second rail. When the operating member is moved from an initial position to a non-initial position, the operating member is configured to drive the driving member to move to further drive the locking member to move, in order to unlock the second rail relative to the first rail at the predetermined position.

A bidirectional drawer system is disclosed. The bidirectional drawer system can include a frame. The bidirectional drawer system can also include first and second drawers slidably coupled to the frame. Each of the first and second drawers can be movable between a retracted position and first and second extended positions on opposite sides of the retracted position. In addition, the bidirectional drawer system can include a drawer interlock mechanism. The drawer interlock mechanism can include first and second interlock portions associated with the first and second drawers, respectively. The first interlock portion can have a cam with a cam surface, and a cam follower operable to interface with the cam surface. The second interlock portion can have a cam lock with a cam lock surface, and cam follower operable to interface with the cam lock surface. With the first and second drawers in the retracted positions, movement of the first drawer toward the first extended position can cause the cam follower of the first interlock portion to engage the cam surface and the cam follower of the second interlock portion to engage the cam lock surface thereby preventing movement of the second drawer out of the retracted position.

A cabinet includes drawers each having a rear latch; and a key driven internal locking device including a rod including a front key hole and a rear bent member; a longitudinal member secured to an inner surface of a rear end of the cabinet and including a longitudinal groove; a sliding member slidably disposed in the longitudinal groove and including rectangular openings on a front surface, a protrusion on a top of the sliding member, and an upper driven member secured to the front surface of the sliding member and having a through hole with the bent member passing through; fastening plates each secured to two sides of the longitudinal member wherein the uppermost fastening plate has a pivot hole with the rear end of the rod passing through into the longitudinal member; and a concave member in an upper portion of the longitudinal member.

Disclosed herein is a safety system for a chest of drawers having drawers. The safety system includes: a sensing unit configured to detect a signal when each of drawers is pulled forward; a drive unit configured to include a drive source and a sliding unit which is linearly moved by the operation of the drive source; and a control unit configured to perform control so that the drive unit operates in accordance with a distance, to which the drawer has been pulled forward, based on the signal of the sensing unit.

A slide rail mechanism is provided and includes a first slide rail assembly, a second slide rail assembly and a connecting member. The first slide rail assembly includes a first rail and a second rail longitudinally displaceable with respect to the first rail. The second slide rail assembly includes a third rail and a fourth rail longitudinally displaceable with respect to the third rail. The connecting member is moved for preventing the fourth rail from displacing with respect to the third rail along an opening direction when the second rail displaces with respect to the first rail along the opening direction.

A slide rail assembly includes first and second rails, a stop, a first engaging member, and a first releasing member. The second rail can be displaced between a retracted position and an extended position with respect to the first rail. The stop is located at the first rail. The first engaging member, movably connected to the second rail, is at an engaged position with respect to the stop when the second rail is at the retracted position with respect to the first rail. The first releasing member is configured to operatively drive the first engaging member away from the engaged position so that the second rail can be displaced from the retracted position toward the extended position with respect to the first rail.

An interlocking apparatus includes an interlocking component and at least two drawer side panels. The drawer side panels are arranged vertically. A sliding groove is formed on each of the at least two drawer side panels. The sliding groove comprises a locking segment and a sliding segment, with the locking segment being communicated with the sliding segment. The locking segment is vertically positioned, with a lower portion of the locking segment communicated with and connected to a starting portion of the sliding segment. The sliding segment is inclined upwards along a depth direction of a drawer. Each of the drawer side panels is slidably connected to the interlocking component via the sliding groove. When one of the drawer side panels is located within the sliding segment of one sliding groove, the remaining drawer side panels are located within the locking segments of the corresponding sliding grooves.
