Abstract

A slide rail assembly is configured to mount a chassis to a rack. A plurality of mounting members are arranged at one side of the chassis. The slide rail assembly includes a first rail, a second rail and a guiding base. The second rail includes a side wall and a bottom wall. The guiding base is disposed at a front end of the second rail. The guiding base defines an entry, an exit and a passage located between the entry and the exit. The second rail is moved out of the rack relative to the first rail. The bottom wall of the second rail abuts against a bottom part of the chassis for pushing the chassis into the rack. The chassis is mounted to the second rail through guiding the plurality of mounting members by the entry to pass through the passage and the exit.

First claim

What is claimed is:

1. A slide rail assembly, configured to mount a chassis to a rack, a plurality of mounting members being arranged at one side of the chassis, the slide rail assembly being mounted to the rack through a pair of brackets, the slide rail assembly comprising:
a first rail;
a second rail movable relative to the first rail along a longitudinal direction, the second rail comprising a side wall and a bottom wall perpendicularly connected to the side wall; and
a guiding base arranged at a front end of the second rail, the guiding base comprising a first guiding section and a second guiding section, the first guiding section and the second guiding section defining an entry, an exit and a passage located between the entry and the exit;
wherein during mounting the chassis to the rack, the second rail is moved out of the rack relative to the first rail, in order to allow the bottom wall of the second rail to abut against a bottom part of the chassis for further pushing the chassis into the rack, the chassis is mounted to the second rail through guiding the plurality of mounting members by the entry of the guiding base to pass through the passage and the exit of the guiding base.

2. The slide rail assembly of claim 1 , wherein a plurality of elongated holes are formed on the side wall of the second rail, the second rail is connected to the first rail by a plurality of connecting members with each of the connecting members passing through one of the plurality of elongated holes, such that the second rail is movable relative to the first rail.

3. The slide rail assembly of claim 1 , wherein a front end of the first rail has a protrusion facing the side wall of the second rail, such that when the second rail is moved out of the rack relative to the first rail, the second rail is deflected by the protrusion of the first rail.

4. The slide rail assembly of claim 1 , further comprising a blocking member movably mounted on the second rail, a portion of the blocking member being located in the passage of the guiding base.

5. The slide rail assembly of claim 4 , wherein the blocking member is configured to be operatively moved away from the passage of the guiding base, in order to allow the chassis to be detached from the second rail.

6. The slide rail assembly of claim 4 , wherein the blocking member has an abutting feature, and the blocking member is configured to be operatively moved away from the passage of the guiding base for being held at an abutting position outside the passage of the guiding base by the abutting feature.

7. The slide rail assembly of claim 6 , wherein the first rail has a releasing feature corresponding to the blocking member at the abutting position, and one of the releasing feature and the blocking member has an inclined surface configured to push the blocking member away from the abutting position when the second rail is retracted relative to the first rail.

8. The slide rail assembly of claim 1 , further comprising an engagement member arranged on the second rail, wherein one of the pair of brackets has a mounting base, the engagement member is engaged with the mounting base when the second rail is retracted relative to the first rail.

9. The slide rail assembly of claim 8 , further comprising an elastic member configured to provide an elastic force to the second rail, wherein when the engagement member is disengaged from the mounting base, the second rail is driven to move relative to the first rail by the elastic force of the elastic member.

10. The slide rail assembly of claim 1 , wherein one of the first guiding section and the second guiding section of the guiding base has an inclined guiding surface located at the entry, such that a width of the entry is greater than a width of the passage.

11. The slide rail assembly of claim 1 , wherein a first transverse width is defined between the side wall and an edge of the bottom wall of the second rail, a second transverse width is defined between the entry of the guiding base and the edge of the bottom wall of the second rail, a third transverse width is defined between the mounting member of the chassis and the edge of the bottom wall of the second rail, the third transverse width is between the first transverse width and the second transverse width.

12. The slide rail assembly of claim 1 , wherein the guiding base further comprises a third guiding section located above the first guiding section and configured to guide the chassis above the third guide section to be dropped on the front end of the second rail.

13. The slide rail assembly of claim 12 , wherein the third guiding section is extended from an upper portion of the first guiding section and bent outwardly.
