When the user causes the interface to move into the rotatable position, it can be rotated to re-align any or all of the unlocking cavities with the locking bar. Inasmuch as each unlocking cavity is also associated with a particular elevation of the interface's respective key follower, re-aligning one or more such cavities resets the respective elevations of the key followers so that they can accept only a different valid key. | 03-13-2014 |
20140109633 | MANUALLY DRIVEN ELECTRONIC DEADBOLT ASSEMBLY WITH FREE-SPINNING BEZEL - A manually driven electronic deadbolt assembly configured with an electro mechanical coupling mechanism to selectively couple a manually operable bezel to a torque blade for operation of a deadbolt mechanism. The electro-mechanical coupling mechanism is configured such that in a locked condition the manually operable bezel is drivably decoupled from the torque blade, such that the manually operable bezel is free-spinning when rotated so as to be rendered incapable of rotating the torque blade to operate the deadbolt mechanism. Also, the electro-mechanical coupling mechanism is configured to drivably couple the manually operable bezel to the torque blade when a valid code is input to a code input mechanism to facilitate the unlocked condition, such that a rotation of the manually operable bezel effects a rotation of the torque blade to operate the deadbolt mechanism. | 04-24-2014 |
20140260461 | REMOVABLE KEY CASSETTE ASSEMBLY - A lock assembly is provided that includes: a lock cylinder having a bore disposed therein and at least one pocket located adjacent the periphery of the bore; a plug including a cassette slot; a plunger that fits in the plug; a locking tab having a slot disposed therein; the slot of the locking tab receives a portion of the plunger; a cassette having a key slot configured to receive a key; the cassette includes a tool slot configured to receive a tool to selectively engage the plunger to selectively move at least a portion of the locking tab into and out of the pocket; when a portion of the locking tab is located in the pocket the locking tab does not block the cassette from being removed from the plug. | 09-18-2014 |
20140265357 | DEADBOLT LATCH ASSEMBLY - A deadbolt latch assembly is provided which includes a housing, bolt, slide, and a pivot member. The bolt is movable, at least partially, into and out of the housing. The slide is located inside the housing and coupled to the bolt to move the bolt, at least partially, into and out of the housing. The slide also includes a plurality of slots. The pivot member includes a plurality of cam members extending therefrom. Each cam member is configured to engage one of the plurality of slots on the slide. | 09-18-2014 |
