Slide rail assembly

Abstract

A slide rail assembly includes a first rail, a second rail, a first working member, a second working member, and a stop. The first working member is movably mounted to the first rail; the second working member is arranged to the second rail; when the second rail is displaced relative to the first rail from an extended position to a retracted position in a retracting direction, the stop ensures that the first working member and the second working member are mutually engaged.

Claims

1. A slide rail assembly, comprising: a first rail; a second rail longitudinally displaceable relative to the first rail, and the second rail having a predetermined feature; a first working member movably mounted to the first rail; a second working member arranged to the second rail; and a stop member mounted to the first rail; wherein, During the process of the second rail moving relative to the first rail from an extended position to a retracted position to a predetermined position, the stop is in a blocking state to block the first working piece in a first working state; wherein, during the process of the second rail moving relative to the first rail from the predetermined position to a retracted position to a retracted position, a predetermined feature of the second rail is used to drive the stop from the blocking state to a non-blocking state, so as to allow the first working piece to move from the first working state to a second working state, so that the first working piece locks the second working piece.

2. The slide rail assembly as described in claim 1 further includes an auxiliary component movably mounted to the first rail; when the auxiliary component receives a predetermined force, the auxiliary component drives the first working component to move from the first working state to the second working state, so that the first working component engages the second working component, and the second rail can be displaced in the closing direction to the closing position.

3. The slide rail assembly as described in claim 2, wherein, The first rail has a first end and a second end that are positioned opposite each other, and the first rail is provided with a bracket adjacent to the first end of the first rail; the first working part and the auxiliary part are respectively pivotally connected to the bracket through a first shaft and a second shaft.

4. The slide rail assembly as described in claim 3, wherein, The stop is movably mounted to the bracket of the first rail.

5. The slide rail assembly as described in claim 4, wherein, The stop can be linearly and movably mounted to the bracket.

6. The slide rail assembly as described in claim 4 further includes an auxiliary elastic element for providing elastic force to the stop.

7. The slide rail assembly as described in claim 3, wherein, When the auxiliary component receives the predetermined force, the auxiliary component moves from a first auxiliary state to a first predetermined direction to a second auxiliary state, thereby driving the first working component to move from the first working state to the second predetermined direction to the second working state; wherein the first predetermined direction and the second predetermined direction are opposite directions.

8. The slide rail assembly as described in claim 7 further includes an elastic element for providing elastic force to the auxiliary element.

9. The slide rail assembly as described in claim 1, wherein, The second rail has a first end and a second end that are positioned opposite each other, and the second working piece is movably mounted to the second rail and is adjacent to the first end of the second rail.

10. The slide rail assembly as described in claim 9, wherein, The second rail is provided with a housing, and the second working part is movably mounted to the housing of the second rail.

11. The slide rail assembly as described in claim 9, wherein, The second working piece is pivotally connected to the second rail.

12. The slide rail assembly as claimed in claim 10 further includes an operating member disposed on one of the housing and the second rail; when the second rail is in the retracted position relative to the first rail and an operating force is applied to the operating member, the operating member is used to drive the second working member to disengage from the first working member.

13. A slide rail assembly, comprising: an outer rail; an inner rail longitudinally displaceable relative to the outer rail, and the inner rail having a predetermined feature; a middle rail movably mounted between the outer rail and the inner rail; a first working piece movably mounted to the outer rail; a second working piece movably mounted to the inner rail; and a stop movably mounted to the outer rail; wherein, During the process of the inner rail moving relative to the outer rail from an extended position to a retracted position to a predetermined position, the stop is in a blocking state to block the movement path of the first working piece, so that the first working piece is in a first working state; wherein, during the process of the inner rail moving relative to the outer rail from the predetermined position to a retracted position to a closed position, a predetermined feature of the inner rail is used to drive the stop from the blocking state to a non-blocking state, so as to allow the first working piece to move from the first working state to a second working state, so that the first working piece locks the second working piece; wherein, by locking the second working piece by the first working piece, the inner rail is prevented from moving relative to the outer rail from the closed position to an opening direction.

14. The slide rail assembly as described in claim 13, wherein, The stop can move linearly relative to the outer rail.

15. The slide rail assembly as described in claim 13 further includes an auxiliary elastic element for providing elastic force to the stop.

16. The slide rail assembly as described in claim 13 further includes an auxiliary component movably mounted to the outer rail; when the auxiliary component receives a predetermined force, the auxiliary component drives the first working component to move from the first working state to the second working state, so that the first working component engages the second working component, and the inner rail can be displaced in the closing direction to the closing position.

17. The slide rail assembly as described in claim 16, wherein, When the auxiliary component receives the predetermined force, the auxiliary component moves from a first auxiliary state to a first predetermined direction to a second auxiliary state, thereby driving the first working component to move from the first working state to the second predetermined direction to the second working state; wherein the first predetermined direction and the second predetermined direction are opposite directions; the slide rail assembly further includes an elastic element to provide elastic force to the auxiliary component.

18. The slide rail assembly as described in claim 17, wherein, The inner rail has a first end and a second end that are positioned opposite each other, and the second working piece is movably mounted to the inner rail and is adjacent to the first end of the inner rail.

19. The slide rail assembly as claimed in claim 18 further includes an operating member disposed to one of a housing and the inner rail, and the housing being fixed to the inner rail; when the inner rail is in the retracted position relative to the outer rail and an operating force is applied to the operating member, the operating member is used to drive the second working member to disengage from the first working member.

20. The slide rail assembly as described in claim 19, wherein, When the inner rail is in the retracted position relative to the outer rail, and the operating force is applied to the operating member, the operating member is used to drive the second working member to disengage from the first working member, thereby allowing the inner rail to move relative to the outer rail from the retracted position to the opening direction.
