Abstract

A slide rail assembly includes a first rail, a second rail, a releasing member and a limiting member. The second rail is movable relative to the first rail. The releasing member is mounted on the second rail. The limiting member is arranged to be corresponding to the releasing member. The limiting member is configured to be in a free status and a limiting status. When the limiting member is in the free status, the releasing member is configured to be operatively moved from a first position to a second position. When the limiting member is in the limiting status, the releasing member is not able to be operatively moved from the first position to the second position.

First claim

1 - 6 . (canceled)

7 . A chassis system, comprising:
a first chassis; a second chassis detachably mounted on the first chassis; and a slide rail assembly, comprising:
a first rail comprising a blocking feature;
a second rail movable relative to the first rail along a longitudinal direction, the second rail mounted on the first chassis;
a first releasing member mounted on the second rail and configured to abut against the blocking feature; and
a limiting member mounted on the second rail and corresponding to the first releasing member;
wherein when the second chassis is mounted on the first chassis, the limiting member is moved toward the first rail by the second chassis, in order to further limit the first releasing member, such that the first releasing member is not able to be pressed to move, in order to prevent the first releasing member from disengaging from the blocking feature;
wherein when the second chassis is detached from the first chassis, the first releasing member is able to be pressed to move, in order to allow the first releasing member to be disengaged from the blocking feature.

8 . The chassis system of claim 7 , wherein when the second rail is moved relative to the first rail from a retracted position to a first extended position, the first releasing member is configured to abut against the blocking feature.

9 . The chassis system of claim 7 , wherein the blocking feature is located adjacent to an end of the first rail.

10 . The chassis system of claim 8 , wherein the first releasing member comprises a first end part, a second end part and an operating part connected between the first end part and the second end part, the operating part has a slot, the second rail comprises a first part and a second part, a step is formed between the first part and the second part, the first end part of the first releasing member is mounted to the first part of the second rail, the second end part of the releasing member abuts against the second part of the second rail, the operating part of the first releasing member is configured to be operatively moved according to the step, in order to allow the releasing member to be disengaged from the blocking feature of the first rail.

11 . The chassis system of claim 10 , wherein a through hole is formed on the second rail and corresponding to the first releasing member, the limiting member comprises an elastic part extended along a transverse direction, the limiting member is configured to be driven by the second chassis to abut against the first releasing member, such that the first releasing member is not able to be pressed to move.

12 . The chassis system of claim 10 , wherein the slide rail assembly further comprises a second releasing member mounted on the second rail, when the second rail is moved relative to the first rail from the first extended position to a second extended position, the second releasing member is configured to abut against the blocking feature of the first rail.

13 . A chassis system, comprising:
a first chassis having an inner space, the first chassis comprising a wall, an opening formed on the wall and communicated with the inner space; a second chassis detachably mounted on the first chassis; a slide rail assembly, comprising:
a first rail comprising a blocking feature;
a second rail movable relative to the first rail along a longitudinal direction;
a first releasing member mounted on the second rail, wherein when the second rail is moved relative to the first rail from a retracted position to a first extended position, the first releasing member is configured to abut against the blocking feature;
a limiting member arranged to be corresponding to the first releasing member, the limiting member having an elastic part passing through the opening of the first chassis to be located in the inner space of the first chassis;
wherein a through hole is formed on the second rail and corresponding to the first releasing member, when the second chassis is mounted in the inner space of the first chassis, the limiting member is moved toward the first rail by the second chassis, in order to further limit the first releasing member, such that the first releasing member is not able to be pressed to move, in order to prevent the first releasing member from disengaging from the blocking feature;
wherein when the second chassis is detached from the first chassis, the first releasing member is able to be pressed to move, in order to allow the first releasing member to be disengaged from the blocking feature of the first rail.

14 . The chassis system of claim 13 , wherein the blocking feature is located adjacent to an end of the first rail.

15 . The chassis system of claim 13 , wherein the first releasing member comprises a first end part, a second end part and an operating part connected between the first end part and the second end part, the operating part has a slot, the second rail comprises a first part and a second part, a step is formed between the first part and the second part, the first end part of the releasing member is mounted to the first part of the second rail, the second end part of the releasing member abuts against the second part of the second rail, the operating part of the releasing member is configured to be operatively moved according to the step.

16 . The chassis system of claim 15 , further comprising a second releasing member mounted on the second rail, when the second rail is moved relative to the first rail from the first extended position to a second extended position, the second releasing member is configured to abut against the blocking feature of the first rail.

17 . The chassis system of claim 13 , further comprising a housing configured to accommodate the first chassis, wherein the slide rail assembly further comprises a fixed rail mounted on the housing, the first rail is movable relative to the fixed rail.
