Abstract

A chassis sled for carrying information handling resources may include a sled housing, a lever mechanically coupled to the sled housing and for aiding a user in engaging the chassis sled with and disengaging the chassis sled from a chassis, and a lever release mechanism mechanically coupled to the lever and the sled housing. The lever release mechanism may be configured to facilitate rotatable translation of the lever relative to the sled housing between a closed position and an open position and vice versa and in the closed position, slidably translate the lever between an unsecured position and a secured position and vice versa.

First claim

What is claimed is:

1. A chassis sled for carrying information handling resources, comprising:
a sled housing;
a lever mechanically coupled to the sled housing and for aiding a user in engaging the chassis sled with and disengaging the chassis sled from a chassis; and
a lever release mechanism mechanically coupled to the sled housing and including the lever, the lever release mechanism configured to:
facilitate rotatable translation of the lever relative to the sled housing between a closed position and an open position and vice versa; and
in the closed position, slidably translate the lever between an unsecured position and a secured position and vice versa;

wherein the lever release mechanism further comprises an internal linking member slidably coupled to the sled housing; and
wherein the lever release mechanism further comprises a locking cam rotatably coupled to the sled housing and configured to, responsive to the lever being slidably translated from the secured position to the unsecured position, mechanically engage with the internal linking member such that the internal linking member is configured to disengage from the lever.

2. The chassis sled of claim 1 , wherein the lever release mechanism is configured to cause the lever to slidably translate between the unsecured position and the secured position responsive to the lever being rotatably translated between the open position and the closed position.

3. The chassis sled of claim 1 , wherein the lever release mechanism comprises a spring mechanically coupled to the sled housing and configured to cause the lever to slidably translate between the unsecured position and the secured position responsive to the lever being rotatably translated between the open position and the closed position.

4. The chassis sled of claim 3 , wherein the internal linking member is mechanically coupled to the spring and configured to: mechanically disengage from the lever prior to translation of the lever from the closed position to the open position; and responsive to the lever being rotatably translated between the open position and the closed position, engage with the lever such that a spring force of the spring causes the lever to slidably translate between the unsecured position and the secured position.

5. The chassis sled of claim 1 , wherein the lever release mechanism further comprises a sled cam rotatably coupled to the sled housing and configured to engage with the lever when the lever is in the unsecured position and the open position to facilitate rotation of the lever between the open position and the closed position and vice versa.

6. The chassis sled of claim 5 , wherein the sled cam is further configured to mechanically engage with the chassis responsive to rotation of the lever from the open position to the closed position in order to maintain the chassis sled within the chassis.

7. A method comprising:
mechanically coupling a lever to a sled housing of a chassis sled for carrying information handling resources, the lever for aiding a user in engaging the chassis sled with and disengaging the chassis sled from a chassis; and
mechanically coupling a lever release mechanism to the sled housing such that the lever release mechanism is configured to:
facilitate rotatable translation of the lever relative to the sled housing between a closed position and an open position and vice versa; and
in the closed position, slidably translate the lever between an unsecured position and a secured position and vice versa;

wherein the lever release mechanism further comprises an internal linking member slidably coupled to the sled housing; and
wherein the lever release mechanism further comprises a locking cam rotatably coupled to the sled housing and configured to, responsive to the lever being slidably translated from the secured position to the unsecured position, mechanically engage with the internal linking member such that the internal linking member disengages from the lever.

8. The method of claim 7 , wherein the lever release mechanism is configured to cause the lever to slidably translate between the unsecured position and the secured position responsive to the lever being rotatably translated between the open position and the closed position.

9. The method of claim 7 , wherein the lever release mechanism comprises a spring mechanically coupled to the sled housing and configured to cause the lever to slidably translate between the unsecured position and the secured position responsive to the lever being rotatably translated between the open position and the closed position.

10. The method of claim 9 , wherein the internal linking member is mechanically coupled to the spring and configured to: mechanically disengage from the lever prior to translation of the lever from the closed position to the open position; and responsive to the lever being rotatably translated between the open position and the closed position, engage with the lever such that a spring force of the spring causes the lever to slidably translate between the unsecured position and the secured position.

11. The method of claim 7 , wherein the lever release mechanism further comprises a sled cam rotatably coupled to the sled housing and configured to engage with the lever when the lever is in the unsecured position and the open position to facilitate rotation of the lever between the open position and the closed position and vice versa.

12. The method of claim 11 , wherein the sled cam is further configured to mechanically engage with the chassis responsive to rotation of the lever from the open position to the closed position in order to maintain the chassis sled within the chassis.

13. An information handling system comprising:
a chassis; and
a chassis sled for carrying information handling resources, comprising:
a sled housing;
a lever mechanically coupled to the sled housing and for aiding a user in engaging the chassis sled with and disengaging the chassis sled from the chassis; and
a lever release mechanism mechanically coupled to the sled housing, the lever release mechanism configured to:
facilitate rotatable translation of the lever relative to the sled housing between a closed position and an open position and vice versa;
in the closed position, slidably translate the lever between an unsecured position and a secured position and vice versa;

wherein the lever release mechanism further comprises an internal linking member slidably coupled to the sled housing; and
wherein the lever release mechanism further comprises a locking cam rotatably coupled to the sled housing and configured to, responsive to the lever being slidably translated from the secured position to the unsecured position, mechanically engage with the internal linking member such that the internal linking member is configured to disengage from the lever.

14. The information handling system of claim 13 , wherein the lever release mechanism is configured to cause the lever to slidably translate between the unsecured position and the secured position responsive to the lever being rotatably translated between the open position and the closed position.

15. The information handling system of claim 13 , wherein the lever release mechanism comprises a spring mechanically coupled to the sled housing and configured to cause the lever to slidably translate between the unsecured position and the secured position responsive to the lever being rotatably translated between the open position and the closed position.

16. The information handling system of claim 15 , wherein the internal linking member is mechanic
