Slide rail assembly

Abstract

A slide rail assembly includes a first rail, a second rail, a locking member, an operating member, and a resilient member. The operating member is used to connect to the locking member. When the second rail is in a retracted position relative to the first rail, the second rail can be locked in the retracted position by the locking member being in a locked state. By operating the operating member from a first operating position to a second operating position, the locking member can be driven from the locked state to an unlocked state, and the locking member is engaged with the resilient member, so that the operating member is held in the second operating position.

When the second rail moves relative to the first rail from the retracted position to a predetermined extended position, the working member is supported by the second support portion, so that the working member no longer abuts against the elastic member, causing the elastic member to release its elastic force and be in a second state. The second locking segment of the elastic member and the first locking segment of the locking member engage with each other, keeping the locking member in the unlocked state and keeping the operating member in the second operating position. During the process of the second rail moving relative to the first rail from the predetermined extension position to the retracted position, the working part is supported by the first support part again, and the working part abuts against the elastic member, so that the elastic member accumulates the elastic force and is in the first state. The second locking section of the elastic member and the first locking section of the lock member disengage from each other, so as to allow the lock member to return from the unlocked state to the locked state and lock the predetermined structure of the first rail again. The operating member returns from the second operating position to the first operating position.

17. A slide rail assembly suitable for a frame, the slide rail assembly comprising: a first rail for mounting to the frame, the first rail having a predetermined structure and a guide structure, the guide structure including a first support portion and a second support portion; a second rail longitudinally displaceable relative to the first rail; an auxiliary device pivotally connected relative to the second rail; a locking member movable relative to the second rail, the locking member including a first locking section; an operating member for operating the locking member; an elastic member arranged to the second rail, the elastic member including a second locking section; and a working member movable relative to the second rail; wherein, When the second rail is in a retracted position relative to the first rail, the locking member, which is in a locked state, locks the predetermined structure of the first rail to prevent the second rail from leaving the retracted position. When the second rail is in the retracted position relative to the first rail, the working member is supported by the first support portion and abuts against the elastic member, causing the elastic member to accumulate elastic force and be in a first state. The second locking segment of the elastic member and the first locking segment of the locking member are mutually unlocked. When a predetermined force is applied to the operating member, causing the operating member to move from a first operating position to a second operating position, the locking member moves from the locked state to an unlocked state and unlocks from the predetermined structure of the first rail, allowing the second rail to move from the retracted position in an opening direction. Specifically, when the second rail moves relative to the first rail from the closed position to the opening direction to a predetermined extension position, the working part is supported by the second support portion, so that the working part no longer abuts against the elastic member, causing the elastic member to release its elastic force and be in a second state. Furthermore, the second locking segment of the elastic member and the first locking segment of the lock engage with each other, keeping the lock in the unlocked state and the operating member in the second operating position. When the operating member is held in the second operating position and the second rail is in the predetermined extension position relative to the first rail, during the movement of the auxiliary device in a first predetermined rotation direction, the auxiliary device will not interfere with the operating member in the second operating position. When the second rail is in the retracted position relative to the first rail, the auxiliary device can pivot in a second predetermined rotation direction opposite to the first predetermined rotation direction, so that the auxiliary device can contact the operating member in the first operating position, so that the operating member is driven from the first operating position to the second operating position by the predetermined force, so that the operating member drives the lock member from the locked state to the unlocked state, so that the lock member is released from the predetermined structure.
