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, the support bracket comprising sidewalls and bottom surface, the support bracket having a guide slot formed in the 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 releasbly coupled to the linkage 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; and
as the handle transitions from the open position to the closed position the linkage moves within the guide slot,

wherein the guide slot is L-shaped having two end portions and a middle portion, and
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.

2. A latch comprising:
a support bracket, the support bracket comprising sidewalls and bottom surface, the support bracket having a guide slot formed in the 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 releasbly coupled to the linkage 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; and
as the handle transitions from the open position to the closed position the linkage moves within the guide slot,

wherein the support bracket is integrally formed within a lid of a housing, and
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.

3. 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, the support bracket comprising sidewalls and a bottom surface, the bottom surface being provided with a guide slot formed therein, a linkage at least partially received within the guide slot, a pin receiveable 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 handle relative to the support bracket along a portion of the guide slot.

4. The method of claim 3 , further comprising removing the pin from the linkage when the latch is in the open position.

5. The method of claim 3 , wherein the guide slot is L-shaped having two end portions and a middle portion.

6. The method of claim 5 , 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.
