Abstract

A securement device is disclosed to aid in the movement or suspension of equipment or people through the air or along inclined surfaces using rope, cable, wire, or similar component and associated lifting, winching, lowering devices, mechanical advantage systems or manual power by retaining a system component between a yoke and a load pin using a load pin assembly. The load pin is biased into a locked position through the use of a biasing member but may be moved from a locked position to a retracted position by journaling a lock pin through a lock slot. Some embodiments restrict movement of the load pin using a track pin and a track slot, while other embodiments use the interaction of a lock ring and a keyed recess formed in the yoke. The securement device may be incorporated as part of a rigging plate.

Dependent claims

A securement device comprising:

a body with an upper portion and a lower portion;
a locking assembly positioned at the lower portion of the body comprising:
a load pin positioned within a yoke configured to accept a system component and secured in place by interaction of a lock pin and a lock slot;
and
a track pin positioned in a track slot formed along the load pin, securing the load pin on an end opposite the lock pin;
wherein a biasing member is configured to bias the load pin in a locked position and the load pin is able to move into a retracted position by moving the track pin through the track slot;
a second locking assembly comprising:
a second load pin positioned within a second yoke configured to accept the system component and secured in place by interaction of a second lock pin and a second lock slot;
and
a second track pin positioned in a second track slot formed along the second load pin, securing the second load pin on an end opposite the second lock pin;
and
wherein the biasing member is configured to bias the second load pin in a locked position and the second load pin is able to move into a retracted position by moving the second track pin through the second track slot.
