Abstract

A slide rail assembly includes a first rail, a second rail and a locking device. The first rail includes a blocking part. The second rail is movable relative to the first rail. The locking device is arranged on the second rail. The locking device includes a first part and a second part. A first space is defined between the first part and the second part. When the second rail is located at a predetermined position relative to the first rail, a second space is defined between the first part and the second part and configured to accommodate the blocking part, and the first part and the second part of the locking device are configured to respectively block two sides of the blocking part of the first rail.

First claim

What is claimed is:

1. A slide rail assembly, comprising:
a first rail comprising a blocking part;
a second rail movable relative to the first rail;
a first locking device arranged on the second rail, the first locking device comprising a first member and a second member, the first member comprising a first part, the second member comprising a second part, a first space being defined between the first part and the second part, wherein the first space is not able to accommodate the blocking part; and
a second locking device arranged on the second rail, the second locking device comprising a third member and a fourth member, the third member comprising a third part, the fourth member comprising a fourth part;
wherein during a process of the second rail being moved relative to the first rail from a retracted position to a first predetermined position along a first direction, the second part of the second member is blocked by the blocking part of the first rail, and the first member is moved with the second rail along the first direction, such that a second space is defined between the first part and the second part, the second space is configured to accommodate the blocking part of the first rail, in order to lock the blocking part to the first locking device;
wherein when the first locking device is operated to unlock the blocking part, and the second rail is further moved relative to the first rail to a second predetermined position along the first direction, a third space defined between the third part and the fourth part is configured to accommodate the blocking part of the first rail, in order to lock the blocking part to the second locking device.

2. The slide rail assembly of claim 1 , wherein when the second locking device is operated to unlock the blocking part, the second rail is movable relative to the first rail from the second predetermined position to the retracted position along a second direction.

3. The slide rail assembly of claim 1 , wherein the first member is fixed to the second rail, and the second member is movable relative to the second rail within a limited range through a guiding feature.

4. The slide rail assembly of claim 1 , wherein the first member further comprises a first elastic section, the first part is arranged at an end of the first elastic section, the second member further comprises a second elastic section, the second part is arranged at an end of the second elastic section.

5. The slide rail assembly of claim 4 , wherein the first elastic section is located between the second rail and the second elastic section, and the first elastic section and the second elastic section are tilted relative to the second rail.

6. The slide rail assembly of claim 5 , wherein the second member further comprises a first extension section connected to the second elastic section, the second rail further comprises a first supporting part configured to abut against the first extension section.

7. The slide rail assembly of claim 1 , wherein the third member further comprises a third elastic section, the third part is arranged at an end of the third elastic section, the fourth member further comprises a fourth elastic section, the fourth part is arranged at an end of the fourth elastic section.

8. The slide rail assembly of claim 7 , wherein the third elastic section is located between the second rail and the fourth elastic section, and the third elastic section and the fourth elastic section are tilted relative to the second rail.

9. The slide rail assembly of claim 8 , wherein the fourth member further comprises a second extension section connected to the fourth elastic section, the second rail further comprises a second supporting part configured to abut against the second extension section.

10. The slide rail assembly of claim 1 , wherein the first rail has a front end and a rear end, the blocking part is arranged adjacent to the front end.

11. The slide rail assembly of claim 1 , wherein the first locking device and the second locking device are arranged at different positions on the second rail along a longitudinal direction of the second rail.

12. The slide rail assembly of claim 3 , further comprising an elastic member configured to apply an elastic force to the second member.

13. A slide rail assembly, comprising:
a first rail comprising a blocking part;
a second rail movable relative to the first rail; and
a first locking device arranged on the second rail, the first locking device comprising a first part and a second part, a first space being defined between the first part and the second part and unable to accommodate the blocking part, wherein when the second rail is located at a first predetermined position relative to the first rail, a second space is defined between the first part and the second part and configured to accommodate the blocking part, the first part and the second part of the first locking device are configured to respectively block two sides of the blocking part of the first rail;
wherein the first locking device comprises a first member and a second member, the first member comprises the first part, the second member comprises the second part, the first member is fixed to the second rail, and the second member is movably mounted to the second rail through a guiding feature;
wherein the slide rail assembly further comprises a second locking device arranged on the second rail, wherein the second locking device comprises a third member and a fourth member, the third member comprises a third part, the fourth member comprises a fourth part, a third space is defined between the third part and the fourth part; wherein when the second rail is located at a second predetermined position relative to the first rail, the third space is configured to accommodate the blocking part of the first rail, and the third part and the fourth part are configured to respectively block two sides of the blocking part of the first rail.

14. The slide rail assembly of claim 13 , further comprising an elastic member configured to apply an elastic force to the second member.

15. A rail kit, comprising:
a slide rail; and
a first locking device arranged on the slide rail, the first locking device comprising a first member and a second member, wherein the first member is fixed to the slide rail, the second member is movably mounted to the slide rail; wherein when the second member is moved relative to the slide rail, a first space defined between the first member and the second member is changed to a second space; wherein the second space is larger than the first space;
wherein when the second member is blocked by an object to move relative to the slide rail, the second space defined between the first member and the second member is configured to accommodate the object, in order to lock the object to the slide rail; wherein the first space is not able to accommodate the object wherein the first member comprises a first elastic section and a first part arranged at an end of the first elastic section, the second member comprises a second elastic section and a second part arranged at an end of the second elastic section, the first space is defined between the first part and the second part, the first elastic section is located between the slide rail and the second elastic section, and the first elastic section and the second elastic section are tilted relative to the slide rail, wherein the second member further comprises a first extension section connected to the second elastic section, the slide rail further comprises a first supporting part configured to abut against the first extension section;
