Abstract

A hook with a latch and trigger mechanism assembly. The assembly includes a hook having a body and an open saddle. A latch is pivotable between a closed position and an open position. A finger handle extends from the body. A finger trigger entirely within a space between the finger handle and the body is movable between a closed rest position and a retracted position permitting movement of the latch to the open position.

Claims

1. A hook with locking latch and trigger mechanism assembly, which assembly comprises:

a hook having a body and an open saddle;

a latch pivotable between a closed position and an open position;

a finger handle extending from said body;

a finger trigger within a space formed between said finger handle and said body, said trigger movable between a rest position and a retracted position permitting movement of said latch to said open position.

2. A hook with latch and trigger mechanism assembly as set forth in claim 1 including a tension spring urging a wedge lock toward said closed position.

3. A hook with latch and trigger mechanism assembly as set forth in claim 1 including an elongated activating pin attached to said finger trigger.

4. A hook with latch and trigger mechanism assembly as set forth in claim 3 wherein said latch includes a recess and said activating pin activates a wedge lock to engage said recess in said latch.

5. A hook with latch and trigger mechanism assembly as set forth in claim 4 wherein said wedge lock is pivotally attached to said hook body with a pivot pin.

6. A hook with latch and trigger mechanism assembly as set forth in claim 1 wherein a compression spring surrounds an activating pin attached to said finger trigger.

7. A hook with latch and trigger mechanism assembly as set forth in claim 1 wherein said finger trigger is pivotally attached to said finger handle.

8. A hook with latch and trigger mechanism assembly as set forth in claim 3 wherein said latch includes a recess and said activating pin engages said recess.

9. A hook with latch and trigger mechanism assembly as set forth in claim 8 including a compression spring surrounding said activating pin.

10. A hook with latch and trigger mechanism assembly as set forth in claim 1 wherein said finger trigger includes an extending slide actuator which is pivotally connected to said latch.

11. A hook with latch and trigger mechanism as set forth in claim 3 wherein said activating pin is pivotally attached to said latch.

12. A hook with latch and trigger mechanism as set forth in claim 11 including a compression spring surrounding said activating pin.
