Abstract: A padlock includes a lock body, a shackle assembled with the lock body, a lock subassembly disposed in a cavity in the lock body, and a shackle retainer assembled with the lock body. The lock subassembly is operable between a locked position securing the shackle in a closed position and an unlocked position permitting movement of the shackle to an open position. The shackle retainer extends into a first shackle bore and is received in a recess in a first leg of the shackle. When the shackle is in the open position, the lock subassembly is manipulable to be moved from a first position to a second position to generate a space in the cavity aligned with the shackle retainer, such that the shackle retainer is extendable into the space for disengagement of the shackle retainer from the first shackle leg recess.

Abstract: A latch and latch handle recessed into the computer cover is provided, with the latch handle preferably presently a cam surface internally that interacts with a compatible cam surface associated with a lock bar. Preferably, a key lock is functionally integrated with the latch in such a way that when the key lock is unlocked the latch handle and latch are free to displace and to then urge the retention bar to disengage detents or hooks from slots or receptacles, by way of releasing the cover from a chassis or body of the desktop or workstation. Accordingly, in essentially one efficient movement via engaging the latch handle, a user will be able to quickly remove the cover.

Abstract: This invention relates to a lock assembly to be used in conjunction with two or more padlock assemblies. The lock assembly comprises a main body 1, a main shackle 2, and a locking portion 7. When all subsidiary padlocks 5, 6 are locked into the apertures 3, 4 the main shackle 2 cannot be opened. The removal of either subsidiary shackle allows the locking portion 7 to circumvent the second subsidiary shackle and the main shackle 2 may be opened. This allows two persons to independently use the padlock without sharing keys or other secure information. Moreover the lock assembly may be used with any secure fitting designed for use with a traditional padlock.

Abstract: A high security hasp-enshrouding lock for securing together a pair of companion locking bars having adjacent apertured hasp portions projecting outwardly in parallel abutment, the lock having a lock body providing with a rearwardly opening cavity to receive the alined abutting hasp portions therein shielded over most of their extent by the lock body and having a shackle bar on a pivoted shackle lever movable transversely through the cavity and hasp apertures to lock the hasp portions against withdrawal. The locking mechanism within the lock body includes a pivoted hasp clamping member along one side of the cavity having a rear portion projecting from the lock body to intercept wedge type attack tools during attempts to wedge the lock from the schackle and having a contact surface defining a side portion of the cavity.
