Locking mechanisms and toolboxes including locking mechanisms are disclosed herein. In one embodiment, a locking mechanism includes a frame including an opening, a lid, a latch coupled to the lid, the latch including a latching post and a flange, and a locking device including a draw mechanism coupled to the tab, where the draw mechanism is translatable with respect to the frame, the draw mechanism including a slot that includes a narrow end and a wide end positioned opposite the narrow end, where the flange has a width that is greater than a width of the narrow end of the slot of the draw mechanism, and where the draw mechanism is repositionable between a latched position in which the narrow end is axially aligned with the latching post of the latch and an unlatched position, in which the wide end is axially aligned with the latching post of the latch.

The trailer emergency air brake supply line coupler is movable between a control position, where air pressure in the supply line causes the trailer emergency air brakes to release so the trailer can be moved, and a park position where the trailer emergency air brake system is vented to automatically engage the trailer emergency air brakes. The lock includes a metal frame attached to the trailer proximate the trailer coupler. First and second spaced side walls extend from the rear wall of the frame on opposite sides of the trailer coupler. A retractable pin extends between the side walls and intersects the path of movement of the supply line coupler preventing movement of the supply line coupler between its control position and its park position. A lock cylinder, padlock or other mechanism retains the pin on the frame.

A locking system for locking of an enclosure that is provided with at least one and preferably two doors or gates is provided. The locking system comprising a lock holding device with a bent piece for mounting of a locking rod behind the door and a blocking element and a lock.

Portable lock mounting assemblies including straps or connectors for securing each assembly to a bicycle or the like. Each mounting assembly having a structure defining a retaining assembly to securely retain a lock and easily release the lock from the mounting assembly.

A cover for a handle of a cargo door to cover hasp elements and a lock. The cover includes a first housing with a first front wall, first side walls each having a front and rear edge, and a top end wall and define a first housing interior. A guide leg and a latch is disposed on the first housing. A second housing includes a second front wall, second side walls, and a bottom end wall that define a second housing interior. The second housing includes a guide socket configured to receive the guide leg and a catch configured to receive and retain the latch. The housing interiors define a cover interior that covers the hasp elements and an installed lock with one of the guide leg and the latch disposed behind the handle and the other of the guide leg and the latch disposed in front of the handle.

A buckle comprising a male coupler including a bar portion with an external surface, a first flange protruding from the external surface, the first flange being adapted for connection of a strap thereto; a female coupler with a hollow body having an opening therein, the opening including an end part at a first axial end of the hollow body and a slot part extending generally axially from the end part of the opening, the slot part having opposing lips extending along the slot, the hollow body having an internal surface complementary to the external surface of the bar portion; a detent for releasably holding the bar portion in the hollow body; and wherein the lips extend reentrantly and each lip is adjacent a respective inwardly-extending face in the bar portion.

A coupler lock device is configured for use with a self-latching trailer coupler securing a hitch ball in the coupler socket. The coupler lock device has a housing that includes a top panel portion defining a cavity configured so that, when the housing is secured in position over the trailer coupler, the housing top panel prevents seating of the hitch ball in the coupler socket by restricting upward movement of the release lever when an attempt is made to insert the hitch ball into the coupler socket. Also, when the housing is secured in position over the trailer coupler with a hitch ball seated in the coupler socket, the housing top panel prevents removal of the coupler socket from the hitch ball by restricting upward movement of the release lever that would otherwise release the coupler socket from the hitch ball.
