Abstract
A rod end lock for latching heavy objects. The rod end lock has a barrel with a mounting end and a latch end. The latch end has a bite portion such that a keeper is secured at a location centered about the axis of the barrel. The mounting end is coaxial with the barrel and has the same centerline. A locking element is movably connected to the barrel and is biased in a closed position such that the locking element and the bite portion form an enclosed space therebetween for latching the keeper. The keeper is released by actuating the locking element to the open position thereby overcoming the bias to the closed position.

A rod end lock for latching a keeper, comprising:
- a barrel having a mounting end and a latch end;
- a mount connection attached to the mounting end of said barrel and coaxial with said barrel;
- a bite portion attached to the latch end of said barrel, said bite portion having a substantially U-shape for acccommodating a rod of the keeper such that when inserted into said bite portion, the rod of the keeper is centered about a centerline of said barrel;
- a locking element pivotally attached to said barrel and having an open and a closed position, said locking element including a pivot point centered on the centerline of said barrel, and a hook portion pivoting about said pivot point wherein when the locking element is in the closed position, said hook portion and said bite portion form an enclosed space therenbetween for latching the rod of the keeper;
- a biasing means for urging said locking element into the closed position;
- and
- a means for actuating said locking element between the opened and closed positions.
A rod end lock for latching a keeper comprising:
- a barrel having a mounting end and a latch end;
- a mount connection attached to the mounting end of said barrel and coaxial with said barrel;
- a bite portion attached to the latch end of said barrel, said bite portion having a shape for accommodating a rod;
- a locking element movably connected to said barrel and having an opened and a closed position;
- and
- a means for actuating said locking element between the opened and closed positions,
- wherein said locking element comprises a pivot shaft connected to said barrel and a hook portion pivoting about said pivot shaft such that when the locking element is in the closed position, said hook portion and said bite portion form an enclosed space therebetween for latching the rod of the keeper, wherein when the rod inserted into the enclosed space, the rod is centered about the centerline of said barrel, the locking element being constructed and arranged to exert no lateral force on the rod.

- a sleeve portion slidably connected about said barrel;
- a spring between said barrel and said sleeve portion urging said sleeve portion away from said mounting end;
- and
- a connecting means between said sleeve and said hook portion such that said hook portion rotates with movement of said sleeve portion.
