The invention provides a unique locking structure having a number of components that form the assembly. The assembly is easy to use and easy to install in an aftermarket application. Further, the assembly can be easily converted to an electronic actuated version without any retooling of the component parts of the assembly. The assembly provides the user with tactile feedback as to its operation.

Abstract: An air brake lock assembly helps to prevent air brake actuation knobs from being actuated. The air brake lock in accordance with the present invention is a theft-prevention device that mounts over the air brake knobs on the dash of a semi-truck cab. It is installed between the dash and the knobs and, when locked, the assembly prevents the knobs from being pushed in. If the air brake knobs cannot be pushed back in, the air brake will remain locked and the truck and trailer will remain immobile. In one embodiment of the present invention, the assembly includes a base and an enclosure for each brake knob. An air brake lock is disposed between the knobs such that the knobs can be selectively locked and unlocked. In one embodiment, the assembly is spring-loaded. In another embodiment, the assembly is not spring-loaded.

Abstract: A free-wheel lock comprises a cylinder, a sleeve, a lock housing, a cam ring, a cam key, a spring, and a lock pawl, the lock pawl comprising lock pawl extension members. The free-wheel lock that is configured to allow a sleeve of the lock assembly to rotate along with a lock cylinder when the lock cylinder is rotated with an incorrect key or by other intrusive means. The free-wheel lock can be used with an air brake lock assembly whereby the lock pawl extension members are configured to engage the recesses of the locking plates to alternatively lock and unlock the air brake knobs of the air brake lock assembly.

Abstract: A hasp seal lock assembly includes a base member that is attached via a hinge to a cover member. The cover member, when rotated such that the cover member engages the base member, is functionally adapted to overlay a latch and seal. The base member and the cover member each have a plurality of apertures defined in adjacent side walls that allow the horizontal latch arm to extend through the assembly. The base member and the cover member also include a second plurality of cooperating apertures whereby the base member and the cover member may be locked together by use of a padlock. In a first preferred embodiment, each cover side wall includes a tab and tab-receiving apertures are defined within the base member. The tabs require that the cover be lifted vertically prior to rotation of the cover member about the base member.

Abstract: The device comprises a box-like housing having a spring-loaded locking plate. The locking plate is secured but movable within the housing. When the locking plate is in a retracted position, which places the device in an “open” position, the device can be positioned over a latch. The locking plate can then be released, which places the device in a “closed” position and allows the device to capture the latch. Once the locking plate is released, a portion of the locking plate extends downwardly from the housing. The downwardly-extending portion of the locking plate includes an aperture, which allows the locking plate to be secured by means of a lock, such as a conventional padlock.

Abstract: An improved hasp seal lock assembly includes a base member that is attached via a hinge to a cover member. The cover member can be rotated approximately 180° from a fully “closed” position, which is when it overlays a latch and seal, to a fully “open” position. The base member and the cover member each have a plurality of apertures defined in adjacent side walls that allow the horizontal latch arm to extend through the assembly. The base member and the cover member also include a second plurality of cooperating apertures whereby the base member and the cover member may be locked together by use of a padlock. In the preferred embodiment, each cover side wall includes a tab and tab-receiving apertures are defined within the base member. The tabs require that the cover be lifted vertically prior to rotation of the cover member about the base member.
