Abstract

A latch having a support bracket having a guide slot formed in a bottom surface. A linkage at least partially received within the guide slot and a handle coupled to the linkage transitionable between an open position and a closed position. A pin releasably coupled to the linkage such that when the handle is in the closed position the pin is coupled to the linkage and in the open position the pin is removable from the linkage. As the handle transitions from the open position to the closed position, the linkage moves within the guide slot.

First claim

What is claimed is:

1 . A latch comprising:
a support bracket having a guide slot formed in a bottom surface; a linkage at least partially received within the guide slot; a handle coupled to the linkage and transitionable between an open position and a closed position; and a pin releasably coupled to the linkage wherein:
when the handle is in the closed position, the pin is coupled the linkage and when the handle is in the open position the pin is removable from the linkage; and
as the handle transitions from the open position to the closed position the rotary moves within the guide slot.

2 . The latch of claim 1 , wherein the support bracket has a receiving space formed by a plurality of sidewalls and the handle is received within the receiving space when in the closed position.

3 . The latch of claim 1 , wherein the pin is stationary while the handle transitions from the closed position to the open position, such that the support bracket is displaced as the linkage moves within the guide slot.

4 . The latch of claim 1 , wherein the guide slot is substantially L-shaped having two end portions and a middle portion.

5 . The latch of claim 4 , wherein the linkage is a rotatory linkage and has a fixed hinge at a first end, and a rotary hinge at a second end and as the rotary hinge transitions from the closed position to the open position, the fixed hinge moves within the guide slot from one of the two end portions to the middle portion and the rotary hinge moves within the guide slot from the middle portion to the other of the two end portions.

6 . The latch of claim 1 , wherein the support bracket is integrally formed within a lid of a housing.

7 . The latch of claim 6 , wherein the housing has a receiving space and the pin has two ends, a first end secured within the receiving space of the housing and a second end receivable in the linkage.

8 . A server assembly comprising:
a housing having a receiving space; a pin coupled to the housing within the receiving space; a lid slidably coupled to the housing; and a latch coupled to the lid, the latch comprising:
a support bracket having a guide slot formed in a bottom surface;
a linkage at least partially received within the guide slot and configured to receive the pin; and
a handle coupled to the rotary linkage and transitionable between an open position and a closed position wherein:
when the handle is in the closed position the pin is coupled to the linkage and when the handle is in the open position the pin is removable from the linkage;
as the handle transitions from the open position to the closed position the linkage moves within the guide slot;
as the handle transitions from the closed position to the open position, the lid slides relative to the housing, thereby decoupling from the housing and providing access to the receiving space.

9 . The server of claim 8 , wherein the support bracket has a handle receiving space formed by a plurality of sidewalls and the handle is received within the handle receiving space when in the closed position.

10 . The server of claim 8 , wherein in the closed position the lid is engaged by at least one sidewall of the housing.

11 . The server of claim 8 , wherein the guide slot is substantially L-shaped having two end portions and a middle portion.

12 . The server of claim 11 , wherein the linkage is a rotatory linkage and has a fixed hinge at a first end, and a rotary hinge at a second end and as the rotary hinge transitions from the closed position to the open position, the fixed hinge moves within the guide slot from one of the two end portions to the middle portion and the rotary hinge moves within the guide slot from the middle portion to the other of the two end portions.

13 . A method of operating a latch assembly for providing access to a housing, the method comprising:
actuating a handle of a latch assembly having a support bracket with a guide slot formed therein, a linkage at least partially received within the guide slot, a pin receivable within at least a portion of the linkage, and a handle coupled with the linkage such that the linkage transitions within the guide slot from a first position to a second position as the handle transitions from a closed position to an open position thereby transitioning the latch from a closed position to an open position; and displacing the support bracket relative to the handle along a portion of the guide slot.

14 . The method of claim 13 , further comprising removing the pin from the linkage when the latch is in the open position.

15 . The method of claim 13 , wherein the guide slot is substantially L-shaped having two end portions and a middle portion.

16 . The method of claim 15 , wherein the linkage is a rotatory linkage and has a fixed hinge at a first end, and a rotary hinge at a second end and as the rotary hinge transitions from the first position to the second position, the fixed hinge moves within the guide slot from one of the two end portions to the middle portion and the rotary hinge moves within the guide slot from the middle portion to the other of the two end portions.
