Abstract

A slide rail assembly includes a supporting rail, a first rail, a second rail, and an interlock device. The second rail can be displaced with respect to the first rail. The interlock device is movably disposed between the first rail and the supporting rail. The second rail displaces the interlock device while being displaced from a retracted position with respect to the first rail to a predetermined position in an opening direction.

First claim

What is claimed is:

1. A rack system comprising:
a rack;
a chassis, the chassis including a wall having an opening formed therein;
a linking member; and
a slide rail assembly, the slide rail assembly including:
a first slide rail assembly including a first rail and a second rail displaceable with respect to the first rail; and
a first interlock device provided between the first rail of the first slide rail assembly and the linking member through the opening of the chassis wall, the first interlock device including:
a first engaging member resiliently biased to extend in a first direction from the linking member to thereby retentively engage the opening of the chassis wall when the chassis is disposed at an installed position within the rack; and
a first locking member, the first locking member is movably connected to the first rail of the first slide rail assembly, and the first engaging member is connected between the first locking member and the linking member;

wherein while being displaced from a retracted position with respect to the first rail of the first slide rail assembly to a predetermined position in an opening direction, the second rail of the first slide rail assembly drives the first locking member together with the first engaging member in a second direction transversely oriented relative to the first direction, and thereby displaces the linking member in the second direction from a first position to a second position.

2. The rack system as claimed in claim 1 , further comprising a supporting frame connected to the first rail of the first slide rail assembly at a position adjacent to an end portion of the first rail, the first locking member of the first interlock device being movable with respect to the supporting frame.

3. The rack system as claimed in claim 2 , wherein the supporting frame has an opening, the first locking member of the first interlock device corresponds to the opening of the supporting frame, and the first engaging member of the first interlock device is inserted through the opening of the supporting frame.

4. The rack system as claimed in claim 1 , wherein one of the second rail of the first slide rail assembly and the first locking member of the first interlock device includes a guiding portion for guiding the second rail of the first slide rail assembly to push the first locking member of the first interlock device.

5. The rack system as claimed in claim 4 , wherein the guiding portion has an inclined section.

6. The rack system as claimed in claim 1 , further comprising an elastic member that applies an elastic force to the first engaging member of the first interlock device.

7. The rack system as claimed in claim 1 , further comprising a second slide rail assembly and a second interlock device, the second slide rail assembly including a first rail and a second rail movable with respect to the first rail, the second interlock device having a blocking portion for blocking the second rail of the second slide rail assembly in response to displacement of the linking member from the first position to the second position.

8. The rack system as claimed in claim 7 , wherein the second interlock device includes a second locking member and a second engaging member, the second locking member is movably connected to the first rail of the second slide rail assembly and is provided with the blocking portion, and the second engaging member is provided between the second locking member and the linking member, wherein while the linking member is displaced from the first position to the second position, the second engaging member drives the second locking member, the blocking portion of the second locking member thereby blocking the second rail of the second slide rail assembly.

9. The rack system as claimed in claim 1 , further comprising a supporting rail mounted on the rack configured to carry the chassis.

10. The rack system as claimed in claim 1 , wherein the first slide rail assembly is mounted on the wall of the chassis.

11. The rack system as claimed in claim 10 , wherein the second rail of the first slide rail assembly is configured for carrying an object.

12. A rack system comprising:
a supporting rail configured to support a chassis;
a first rail having a supporting frame portion;
a second rail displaceable with respect to the first rail;
a linking member displaceable with respect to the supporting rail and the first and second rails; and
an interlock device movably provided between the first rail and the supporting rail, the interlock device including:
an engaging member resiliently biased to extend from the supporting rail towards the first rail in a first direction to retentively engage a supported chassis; and
a locking member movably connected to the first rail and disposed between the engaging member and the linking member;

wherein while being displaced from a retracted position with respect to the first rail to a predetermined position in an opening direction, the second rail displaces the locking member together with the engaging member in a second direction transversely oriented with respect to the first direction, the locking member being thereby displaced responsively in the second direction.

13. The rack system as claimed in claim 12 , wherein the interlock device includes a locking member and an engaging member, the locking member is movably connected to the first rail, and the engaging member is movably connected to the supporting rail, wherein while being displaced from the retracted position with respect to the first rail to the predetermined position, the second rail drives the locking member to displace the engaging member.

14. The rack system as claimed in claim 13 , wherein the supporting frame portion of the first rail has an opening, the supporting rail has an opening, the engaging member includes a first portion and a second portion connected to the first portion, the first portion is inserted through the locking member via the opening of the first rail, and the second portion is inserted through the opening of the supporting rail.
