Abstract: A simplified truck cap handle and lock assembly is provided. Unlike truck cap handle and lock assemblies known in the art, the assembly is comprised of a codeable lock that is disposed in a position that is not perpendicular to the glass access window of the cap. The lock of the present invention is rotated 90° from the perpendicular. Further, the lock is codeable because it is preferably keyed to match other locks and ignition key switch of the vehicle with which the assembly is used. 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 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: 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.

Abstract: A method of mounting a lock to a pick-up truck tailgate latching mechanism including the steps of locating targets for holes to be formed in a plastic bezel, the bezel carrying a handle for the tailgate, forming the holes in the plastic bezel, and securing the locking mechanism to the bezel via the formed holes.

Abstract: A master key lock includes a lock cylinder having a keyway for receiving a key, a sleeve about the cylinder, a plurality of wafer tumblers, a master key and a spring operable to axially move the sleeve relative to the cylinder when the master key is inserted into the keyway. A system that uses the master key lock includes a lock case wherein the sleeve is disposed between the cylinder and the lock case, the sleeve being axially movable within the case. The sleeve comprises a plurality of transversely disposed slots for engaging the plurality of wafer tumblers such that the lock is unlocked by insertion of a key or a master key. A method of using the master key lock is also disclosed.
