  • Patent number: 8562040
    Abstract: An electric lock for remote access control to a container wherein a U-shaped latch is mounted on a door in alignment with a slot in a housing mounted in the container. Upon closure, the latch enters the housing to engage a slotted keeper therein and causes rotation of the keeper. Rotation of the keeper causes a release lever to engage a stepped protrusion on the keeper and secures the keeper and latch. Activation of a solenoid or drive motor coupled to the release lever permits withdrawal of the latch from the housing. The axes of rotation of the keeper and release lever are located to greatly reduce the impact of pre-release forces to the door.

  • Patent number: 5713691
    Abstract: A latch for a hitch having release mechanism including a pair of parallel oriented cylinders which are disposed to lock together two separable elements of a hitch. The locking cylinders are disposed between the confronting surfaces within portions of the separable hitch elements to receive a compression force across the both of the cylinders when the hitch elements are receiving an tensions so as to separate them. To release the hitch elements while under tension, one of the cylinders is rotated, causing the adjacent, parallel disposed cylinder to rotate in the opposite direction, rolling over the confronting surfaces in the same directions, and eventually out of and releasing the two separable hitch elements. Multiple embodiments are shown which relate to variations in hitch styles, and further embodiments relate to smaller clamping devices, such as hand tools, and to rotational couplers which are releasable while under torque.

  • Patent number: 4253698
    Abstract: For automotive use, an inexpensive gasoline tank theft guard adjustably attached so that owner may integrate the guard or not by choice of a quick manual setting. The guard utilizes a gasoline fill-tube cover, a lockable body-entry panel, and the owner's key and perhaps his license plate for intercepting access to the gasoline tank when cover and panel are proximate and closed, and for protection against gasoline theft when entry panel is locked. By way of example, a pin (10, FIGS. 3-6), pivotally anchored inside gasoline fill-tube cover (6) engages a receptacle (9) in the trunk lid (2) when the lid closes (FIG. 5). Owner's key (1) unlocks lid to free pin. Anchor heads (4, FIG. 3) are concealed behind mounted license plate (7, FIG. 4) and are designed to frustrate tampering. Stability and rattle of the adjustable pin are controlled manually (FIG. 7) and automatically (FIG. 8). Pin (10) pivots manually aside to disconnect the system.
