Abstract
A cargo restraint device including a base having an outer pawl and an inner pawl pivotally connected to the base. The outer pawl has a generally horizontal locking surface that cooperates with a generally horizontal locking surface on the inner pawl to provide a cargo restraint device capable of resisting vibration and downward forces applied to the inner pawl to prevent inadvertent disengagement of the cargo restraint device. During an unlocking movement, foot pressure is applied generally downward upon the outer pawl to enable the inner pawl to rotate to an unlocked position. The foot pressure is then released from the outer pawl to enable the outer pawl to rotate to an unlatched position.
Claims10
A cargo restraint device comprising:
- a base;
- an outer pawl pivotally connected to said base, said outer pawl having a first locking surface;
- and
- an inner pawl pivotally connected to said base, said inner pawl having a second locking surface, said outer pawl and said inner pawl being positionable between an operative position where said first locking surface engages said second locking surface and a collapsed position where said first locking surface disengages said second locking surface, said first locking surface and said second locking surface preventing any unlocking pivotal movement of said inner pawl when in said operative position.
A cargo restraint device for retaining a cargo item, said cargo restraint device comprising:
- a base structure;
- a first pawl member having a first locking surface and a second locking surface, said first pawl member being pivotally mounted to said base structure;
- and
- a second pawl member having a third locking surface and a fourth looking surface, said second pawl member being pivotally mounted to said base structure, said first and second pawl members being positionable in a latched position in which said first locking surface engages with said third locking surface and said second locking surface engages with said fourth locking surface;
- said first and second pawl members further being positionable in an unlatched position in which said first locking surface disengages from said third locking surface and enables said first pawl member to freely rotate;
- said first locking surface and said third locking surface preventing any unlatching pivotal movement of said second pawl when in said latched position.
