Abstract

A latch for securing a compute sled into a chassis is provided. The latch includes a body with a user manipulable control, the body configured for mounting to a drawer of the compute sled, the user manipulable control configured for causing a slider to one of engage and disengage a deadbolt with a complimentary slot of a sleeve for containing the drawer, the latch further configured for engaging a retention element of the chassis.

First claim

What is claimed is:

1. A latch for securing a compute sled into a chassis, the latch comprising:
a body with a user manipulable control, the body being mountable to a drawer of the compute sled, the user manipulable control comprising a cam disk that adjusts a slider upwardly and downwardly according to rotation of the user manipulable control, and the cam disk rotates to cause the slider to one of engage and disengage a deadbolt with a sleeve that wraps around sides and bottom of the drawer, the latch further engages a retention element of the chassis; and
a pull handle mounted to the body and fixed to the body by a pin that provides a hinge about which the pull handle rotates, wherein the pull handle facilitates pulling of the drawer from the sleeve when the deadbolt is disengaged from the sleeve,
wherein rotating the pull handle adjusts positioning of a flange that extends laterally from the pull handle and causes a flag to rotate in a rearward direction, which causes the retention element to disengage from an engagement element.

2. The latch as in claim 1 , wherein the user manipulable control comprises a button like structure comprising an engagement feature for engaging a user defined tool.

3. The latch as in claim 1 , wherein the user manipulable control comprises a security button comprising a cross-slot pattern and an indicator that displays a lock status, the indicator comprising an arrow which is oriented to point in one direction or another between a locked and an unlocked position by turning of the security button.

4. The latch as in claim 3 , wherein the pull handle comprises a window that enables observation of a lock status, wherein a user ascertains whether the latch is in a locked position or an unlocked position by peering through the window of the pull handle.

5. The latch as in claim 1 , wherein the pull handle disengages the engagement element of the compute sled from the retention element of the chassis.

6. The latch as in claim 1 , further comprising a spring for biasing the pull handle into a closed position.

7. The latch as in claim 1 , further comprising a clip that provides friction between the slider and the body.

8. The latch as in claim 1 , wherein the chassis is comprised within a rack unit.

9. The latch as in claim 8 , wherein the rack unit mounts in a storage rack.

10. The latch of claim 1 , further comprising a lock and unlock status indicator located on the pull handle, which in combination with the user manipulable control indicates a locked or unlocked security status of the deadbolt or latch when the pull handle is closed.

11. The latch of claim 1 , wherein turning of the user manipulable control causes the disk cam to rotate, which pushes the slider either upwardly or downwardly to cause the deadbolt of the slider to engage the sleeve or to be retracted from the sleeve, wherein the drawer is capable of withdrawn from the sleeve when the deadbolt is retracted.

12. A method for assembling a latch for securing a compute sled into a chassis, the method comprising:
selecting a body for maintaining a user manipulable control, the body being mountable to a drawer of the compute sled, the user manipulable control comprising a cam disk incorporated against the backside of a slider, the user manipulable control causes the slider to one of engage and disengage a deadbolt with a sleeve that wraps around sides and bottom of the drawer, where the latch further engages a retention element of the chassis; and installing the user manipulable control and the slider within the body;
mounting a pull handle to the body and affixing the pull handle to the body by a pin that provides a hinge about which the pull handle rotates, wherein the pull handle facilitates pulling of the drawer from the sleeve when the deadbolt is disengaged from the sleeve, wherein rotating the pull handle adjusts positioning of a flange that extends laterally from the pull handle and causes a flag to rotate in a rearward direction, which causes the retention element to disengage from an engagement element.

13. The method as in claim 12 , further comprising mounting the pull handle to the body with the pin.

14. The method as in claim 13 , further comprising incorporating a spring that biases the pull handle into a closed position.

15. The method as in claim 12 , further comprising incorporating a clip that causes friction between the slider and the body.

16. The method as in claim 12 , further comprising securing the user manipulable control and the slider with a screw.

17. An information handling system (IHS) comprising:
a compute sled that mounts within a chassis of a rack unit, the sled comprising at least one component of the IHS disposed therein; and
a latch that secures the compute sled into the chassis, the latch comprising a body with a user manipulable control, the body providing mounting to a drawer of the compute sled, the user manipulable control comprising a cam disk that adjusts a slider upwardly and downwardly according to rotation of the user manipulable control, and the cam disk rotates to cause the slider to engage and disengage a deadbolt with a sleeve that wraps around sides and bottom of the drawer, the latch further configured for engaging a retention element of the chassis, and the latch further comprising a pull handle mounted to the body and fixed to the body by a pin that provides a hinge about which the pull handle rotates, wherein the pull handle facilitates pulling of the drawer from the sleeve when the deadbolt is disengaged from the sleeve, wherein rotating the pull handle adjusts positioning of a flange that extends laterally from the pull handle and causes a flag to rotate in a rearward direction, which causes the retention element to disengage from an engagement element.

18. The information handling system (IHS) as in claim 17 , further comprising an instrumentality operable system to at least one of compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, and use data.
