Abstract
A protective device for locking two relatively movable objects of a cargo container in a fixed relationship employing a longitudinal bar mechanism pivotally mounted on one of said objects for cooperatively engaging with a pair of keepers mounted on the other of said objects for locking the objects together and a first rod assembly pivotally connected to one end of the bar mechanism and a handle at its other end with the rod moving longitudinally into engagement with one of the keepers. A housing is mounted around the rod assembly through which the rod is movable and defines a recess which exposes a predetermined portion of the length of the rod assembly. An aperture is formed in the predetermined portion of the rod assembly through which a shackle or padlock may be placed to lock the protective device.
Claims5
A protective device for locking two relatively movable objects of a cargo container in a fixed relationship comprising:
- a longitudinal bar mechanism pivotally mounted on one of said objects,
- a first rod assembly pivotally connected to one end of said bar mechanism for movement longitudinally thereof in a first direction for engaging one of a pair of keepers both mounted on the other of said objects and a second rod assembly pivotally connected to said bar mechanism at a point between its ends for movement longitudinally thereof in a direction opposite to the movement of said first rod assembly for engaging the other of said keepers,
- a housing mounted around said first rod assembly through which said first rod assembly is movable.
- said housing comprising a recess which exposes a predetermined portion of the length of said first rod assembly when said first rod assembly is in cooperative engagement with one of said keepers and forms an opening for receiving the shackle of a padlock,
- a first aperture formed in said predetermined portion to extend through said first rod assembly for receiving the shackle of a first padlock when said first rod assembly engages said one of said keepers,
- a wall mounted on one of said objects through which the other end of said bar mechanism extends,
- said other end of said bar mechanism comprising a handle formed on one side of said wall,
- second and third apertures spacedly formed in said wall,
- a flange mounted to extend laterally of said bar mechanism on the other side of said wall juxtapositioned to said wall, and
- a fourth aperture formed in said flange,
- said third and fourth apertures being axially aligned when said handle is moved to protective device locking position and causing said first rod assembly and said second rod assembly into keeper engagement positions,
- whereby when said protective device is in keeper engaging positions the shackle of a second padlock may be extended through said second, third and fourth apertures to form a dual locking function.
