Abstract

A latch apparatus and method to facilitate leveraged insertion of a component into a component bay to an interfaced position, securing of the component in the component bay when the component interfaces with a host computer, leveraged dislodgement of the component from its interfaced position for removal of the component from the component bay, and proper positioning of the latch apparatus upon insertion of the component housing to ensure proper engagement of the latch apparatus with the component bay for leveraged insertion and removal. One latch apparatus comprises a frame adapted to be secured to a proximal end of a component housing, a handle pivotally secured to the frame, and an extendable arm slidably secured to a distal end of the handle and biased toward an extended position, wherein the distal end of the extendable arm has a distally extending latch key for engaging a slot in the component bay.

Claims

1. A latch apparatus, comprising:

a frame adapted to be secured to a proximal end of a component housing;

a handle pivotally secured to the frame intermediate a proximal end and a distal end;

an extendable arm slidably secured to the distal end of the handle, wherein the extendable arm has a distally extending latch key formed on a distal end of the extendable arm, and wherein the extendable arm is biased toward an extended position.

2. The latch apparatus of claim 1, wherein pivotal movement of the handle from an open position to an intermediate position deploys the latch key beyond a lateral edge of the frame for engagement with a slot in a component bay sidewall.

3. The latch apparatus of claim 2, wherein pivotal movement of the handle from the intermediate position to closed position causes the extendable arm to retract to follow the contour of the component bay sidewall and draws the latch key in a proximal direction.

4. The latch apparatus of claim 1, wherein pivotal movement of the handle from a closed position to an intermediate position causes the extendable arm to extend to follow the contour of the component bay sidewall and moves the latch key in a distal direction.

5. The latch apparatus of claim 4, wherein pivotal movement of the handle from the intermediate position to the open position retracts the latch key within the lateral edge of the frame to disengage the slot in the component bay sidewall.

6. The latch apparatus of claim 1, wherein the extendable arm is slidably secured to the handle by a pin and slot coupling.

7. The latch apparatus of claim 1, wherein the extendable arm includes a cam surface that engages and follows the component bay sidewall between the intermediate position and closed position of the handle.

8. The latch apparatus of claim 1, wherein the extendable arm has a limited range of extension so that the latch key aligns with a slot in the drive bay when the extendable arm is fully extended.

9. The latch apparatus of claim 1, wherein the extendable arm is distally biased by a spring.

10. The latch apparatus of claim 1, further comprising:

a spring for biasing the handle toward an open position.

11. The latch apparatus of claim 1, wherein the handle includes a stop arm that prevents the carrier from being fully received in the component bay with the handle in the open position.

12. The latch apparatus of claim 1, further comprising a spring-biased locking pawl for securing the handle in the closed position.

13. The latch apparatus of claim 1, further comprising:

a pair of rails secured to the frame, wherein the pair of rails adapt the frame to be secured to the proximal end of the component housing.

14. The latch apparatus of claim 13, wherein each rail is securely positionable within a channel of a component bay.

15. The latch apparatus of claim 1, wherein the component housing contains a hard disk drive.

16. A method comprising:

securing a latch to a proximal end of a component housing;

inserting the component housing into a component bay between a pair of opposing channels, wherein one of the opposing channels has a slot adjacent a proximal end;

aligning a latch key on one side of the latch with the slot by continuing insertion of the hard disk drive carrier until a latch stop arm limits further insertion;

pivoting a latch handle about a pivot to slidably extend and deploy the latch key into the slot; and

continuing to pivot the handle towards a closed position to move the latch key against a proximal end of the slot adjacent the proximal end of the chassis to impart a docking force to the component housing and displace the component housing further into the component bay until a connector on the component housing has interfaced with a mating connector secured relative to the component bay.

17. The method of claim 16, further comprising the step of:

locking the extendable handle in the closed position.

18. The method of claim 16, further comprising the step of:

pivoting the extendable handle from the closed position towards the open position to impart a dislodging force to the component housing and displace the component housing until the connector on the component housing disconnects from the mating connector; and

continuing to pivot the extendable handle toward the open position to simultaneously retract the latch key from the slot and deploy the latch stop arm.

19. The method of claim 16, wherein pivoting the extendable handle toward the closed position moves a latch stop arm to allow insertion of the disk drive carrier.

20. The method of claim 16, wherein the component housing contains a hard disk drive.
