Slide rail assembly

Abstract

A slide rail assembly includes a first rail, a second rail, a synchronization member, an auxiliary member and a third rail. The synchronization member is movably mounted on the second rail. The third rail is arranged with a working feature. During a process of the third rail being moved along an opening direction, the third rail is configured to drive the second rail to synchronously move by the working feature abutting against the synchronization member. During a process of the third rail and the second rail being synchronously moved along the opening direction, the blocking feature is configured to abut against the auxiliary member to move the auxiliary member relative to the second rail, in order to drive the synchronization member to move to no longer abut against the working feature, so as to unsynchronize movement between the third rail and the second rail.

What is claimed is: 
     
         1 . A slide rail assembly, comprising:
 a first rail arranged with a predetermined feature and a blocking feature;   a second rail longitudinally movable relative to the first rail;   a synchronization member, an engaging member and an auxiliary member movably mounted on the second rail; and   a third rail longitudinally movable relative to the second rail and arranged with a working feature;   wherein during a process of the third rail being moved along an opening direction, the third rail is configured to drive the second rail to synchronously move by the working feature abutting against the synchronization member in a first state;   wherein during a process of the third rail and the second rail being synchronously moved along the opening direction, the blocking feature is configured to abut against the auxiliary member to move the auxiliary member from a first auxiliary position to a second auxiliary position relative to the second rail, in order to drive the synchronization member to switch from the first state to a second state, such that the working feature of the third rail no longer abuts against the synchronization member, so as to unsynchronize movement between the third rail and the second rail;   wherein when the second rail is located at an extended position relative to the first rail, the engaging member is configured to be engaged with the predetermined feature, in order to prevent the second rail from being moved along a retracting direction from the extended position.   
     
     
         2 . The slide rail assembly of  claim 1 , wherein the second rail is movably mounted between the first rail and the third rail. 
     
     
         3 . The slide rail assembly of  claim 1 , wherein the auxiliary member is longitudinally movable relative to the second rail. 
     
     
         4 . The slide rail assembly of  claim 1 , wherein the auxiliary member and the second rail respectively have a first limiting feature and a second limiting feature configured to interact with each other. 
     
     
         5 . The slide rail assembly of  claim 3 , further comprising an elastic member configured to provide an elastic force to the auxiliary member. 
     
     
         6 . The slide rail assembly of  claim 5 , wherein the elastic member is connected between the second rail and the auxiliary member. 
     
     
         7 . The slide rail assembly of  claim 3 , wherein the synchronization member and the engaging member are pivotally connected to the second rail through a shaft member. 
     
     
         8 . The slide rail assembly of  claim 7 , wherein the shaft member is arranged in a direction substantially identical to a height direction of the second rail. 
     
     
         9 . The slide rail assembly of  claim 7 , further comprising an elastic structure configured to provide an elastic force to at least one of the synchronization member and the engaging member. 
     
     
         10 . The slide rail assembly of  claim 1 , wherein the blocking feature is a protrusion. 
     
     
         11 . A slide rail assembly, comprising:
 a first rail arranged with a blocking feature;   a second rail longitudinally movable relative to the first rail;   a synchronization member movably mounted on the second rail;   an auxiliary member movable relative to the second rail between a first auxiliary position and a second auxiliary position; and   a third rail longitudinally movable relative to the second rail and arranged with a working feature;   wherein during a process of the third rail being moved along an opening direction, the third rail is configured to drive the second rail to synchronously move by the working feature abutting against the synchronization member;   wherein during a process of the third rail and the second rail being synchronously moved along the opening direction, the blocking feature is configured to abut against the auxiliary member to linearly move the auxiliary member from the first auxiliary position to the second auxiliary position relative to the second rail, in order to drive the synchronization member to move, such that the working feature of the third rail no longer abuts against the synchronization member, so as to unsynchronize movement between the third rail and the second rail.   
     
     
         12 . The slide rail assembly of  claim 11 , wherein the second rail is movably mounted between the first rail and the third rail. 
     
     
         13 . The slide rail assembly of  claim 11 , wherein the auxiliary member is movably mounted on the second rail. 
     
     
         14 . The slide rail assembly of  claim 11 , wherein the auxiliary member and the second rail respectively have a first limiting feature and a second limiting feature configured to interact with each other. 
     
     
         15 . The slide rail assembly of  claim 13 , further comprising an elastic member configured to provide an elastic force to the auxiliary member. 
     
     
         16 . The slide rail assembly of  claim 15 , wherein the elastic member is connected between the second rail and the auxiliary member. 
     
     
         17 . The slide rail assembly of  claim 13 , wherein the synchronization member is pivotally connected to the second rail through a shaft member. 
     
     
         18 . The slide rail assembly of  claim 17 , wherein the shaft member is arranged in a direction substantially identical to a height direction of the second rail. 
     
     
         19 . The slide rail assembly of  claim 17 , further comprising an elastic structure configured to provide an elastic force to the synchronization member. 
     
     
         20 . The slide rail assembly of  claim 11 , wherein the blocking feature is a protrusion.
