A drawer assembly includes a member having a first locking element. A drawer includes a frame and a handle. The handle includes a first portion and a second portion. The first portion is coupled to the frame. The second portion is coupled to the first portion. A drawer release includes a first end and a second end. The drawer release is rotatably coupled to the drawer. The first end includes a second locking element. The second portion is rotatable relative to the first portion to move the drawer release from a first orientation in which the second locking element directly engages the first locking element to prevent the drawer from sliding relative to the member to a second orientation in which the second locking element is spaced apart from the first locking element to allow the drawer to slide relative to the member. Systems and methods of use are disclosed.

A three-section slide rail device includes an outer section, a middle section and an inner section. The outer section includes an outer rail having an extension block formed on a sliding surface. The middle section includes an anti-retraction locking member pivotably connected with a middle rail. The inner section includes an inner rail having an abutment plate formed on an inner surface. The abutment plate abuts against and urges upwardly the anti-retraction locking member to keep the anti-retraction locking member. When the inner section is moved relative to the middle section to disengage the abutment plate from the anti-retraction locking member, the anti-retraction locking member is permitted to turn downwardly to allow the middle section to move to a short extended state, where the anti-retraction locking member abuts against the extension block to prevent a further extending movement of the middle section.

A sliding rail is adapted to be engaged with an engaging member, and includes a track and a limiting mechanism. The track includes a base wall, two side walls, and two pivoting slots. The limiting mechanism includes first and second operating members, a limiting member, and first and second connecting members. The first operating member is operable for driving the limiting member from a locked position, where the engaging member is contained in a limiting space between the limiting member and one of the side walls, to a first unlocked position, where the limiting member is rotated about the second connecting member to open the limiting space. The second operating member is operable for driving the limiting member from the locked position to a second unlocked position, where the limiting member is rotated about the first connecting member to open the limiting space.

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 slide rail assembly includes a first rail, a second rail, a blocking feature, two operating members and a locking member. The second rail and the first rail are movable relative to each other. The blocking feature is arranged on the first rail. The two operating members and the locking member are movably mounted on the second rail. When the second rail is located at a predetermined position relative to the first rail and when the locking member is in a locking state, the locking member and the blocking feature are configured to block each other to prevent the second rail from being moved away from the predetermined position. When one of the two operating members is operated, the locking member is configured to be driven to move from the locking state to an unlocking state to allow the second rail to be moved away from the predetermined position.
