A locking mechanism for a variety of uses is disclosed. The mechanism consists of a lock housing and one or more flat-bottomed slots in the housing to receive a flange or flanges from an article or articles to be secured to the housing and a key-operated locking shaft reciprocally mounted for movement across each of the slots. The locking mechanism may be used in a manner comparable to a padlock or may be secured to a supporting structure such as a motorcycle and be used to secure articles such ...

A resettable lock of the cylinder type constructed of coaxial cylinders, one inside the other. The rotatable cylinder slidably mounting a plurality of tumblers. The inner wall of the outer cylinder having a radial opening functioning as the open terminal for the tumblers when a key inserted into the lock contacts the various pusher elements and positions all the associated tumblers at the terminal simultaneously. The lock is rendered pick resistant by an element overlying the tumblers.

A housing contains a slider having bores interconnected by slots and a shackle rotatably secured to the slider for movement therewith. Dials are interconnected with tumblers having locking cams rotatable in the bores and slidable in the slots. The tumblers may be disengaged and rotated relative to the dials for changing the combination. Registry of the locking cams with the slots allows movement of the slider to open the shackle.

The deadbolt of a lock mechanism is operable from either side of the door by means of a pair of independently operable cams controlled, respectively, on the inside by a knob and on the outside of the door by a key-cylinder arrangement. The lock may also be operable and controlled from the inside by a key-cylinder arrangement. Each of the cams is arranged to release a detent mechanism which normally restrains the deadbolt from movement from either of its effective length of the key-cylinder which...

A lock, especially for a lock installation, having a housing (3) mounted inside a door (2) of a clothing locker or the like, the housing (3) being for a locking bolt (7) which is moveable by a rotary handle (14) projecting outwardly through the door (2), and, the occurrence, after activation of an electronic verification apparatus (21) and subsequent queries regarding the locking entitlement of a transponder (19), of electrical guidance applying to a locking-assist element (26) to release the lo...

The invention is directed to dead bolt receiver lock that is installed in a boat between the transom and the clamp that mounts an outboard motor to the boat. The dead bolt prevents the unauthorized removal of the outboard motor from the boat. To this end, there is used a dead bolt having at end thereof a rounded head and a another end thereof a threaded end. At the threaded end there mounted a fastening which receives a locking cylinder operated by a key to lock the dead bolt in a locked positio...

A lock, particularly a mortise lock, with bolt (9) and preferably catch (43) and a step-up lever (27) which acts on the bolt (9) and is equipped with a closure engagement opening (30) and is pivoted below the axis of rotation of the closure bit, for the closing of the bolt (9) in forward and backward direction while obtaining a lengthening of the closing stroke; in order to optimize the design, it is proposed that the path of movement of the closing engagement opening (30) extend approximately o...

A lock for a door has a housing with an opening, a latch bolt and a further latch bolt both mounted to the housing for parallel displacement relative to the housing. A latch follower formed as part of a latch is connected to the latch bolt as is a changer, with the parallel displacement occurring due to the action of one of the latch follower via the latch and the changer via a key. A lock cylinder is situated in the housing opening. Two drive rods and associated control plates are provided alon...

A lock apparatus which can be locked or unlocked by an electronic key or mechanical key, includes a cylinder casing, a sleeve disposed rotatably inside the cylinder casing, a key cylinder disposed rotatably inside the sleeve and in which a mechanical key can be inserted, a tumbler disposed on the key cylinder and which the mechanical key can engage, a key cylinder lock actuator for locking or unlocking a rotation of the sleeve with respect to the cylinder casing and a control unit disposed on th...

A key safe having a shackle to secure the key safe to a door knob or the like and a first locking means associated with the shackle to allow installation and removal of the key safe. The key safe has an interior chamber accessed through a removable cover secured by a second locking means independent of the first locking means. Thus the owner or occupant of a premises can provide limited access to the premises for a real estate agent or other authorized person by installing the key safe on the ex...
