Abstract: A vehicle door latch (10) with a power child security lock comprises an enclosure (12) and several components mounted on or in the enclosure. First is a latching assembly (14) disposed in the enclosure and adapted to move between an unlatched configuration and a latched configuration. There is also an inside latch handle assembly (16) disposed adjacent the latching assembly (14).

Abstract: A door lock assembly which includes an electronic card reader is provided whereby when the clutch assembly is in the activated position, rotational movement of the outside handle is transmitted by way of a spindle through the mortise and through the clutch assembly to a clutch disk disposed between the mortise and clutch assemblies and the inside housing. The clutch disk is disposed inside the door. Rotational movement of the clutch disk is then imparted back towards the door through a drive disk and hub drive to the mortise latch hub which is disposed in the mortise housing disposed inside the door structure. As a result, the clutch disk and clutch assembly can be disposed between the inside housing and the inside door surface and the electronic components of the card reader and clutch assembly can be conveniently housed in the inside housing assembly.

Abstract: An anti-tamper locking assembly for locking a position of a block, such as a locking bolt in an electronic lock, electrically moves a pin to engage or dis-engage the block. When dis-engaged, the block can be moved and access or the like can be made. The pin is selectively moved electronically in order to allow access, entry or the like. The pin can be moved with, e.g., a solenoid. The pin has an overhanging portion, or a head portion. In order to prevent an individual from forcing the pin into an un-locked position, the head portion operates in conjunction with at least one spring-arm member and a blocker which are fixed to the block to prevent a user from being able to strike the device with a hammer or the like to "temporarily" move the pin to a position allowing the block to be moved and access or the like to be made.

Abstract: Latching components of a padlock are driven by a motor between latched and released positions. An encoder element with associated optical elements provides position information to a control circuit. The control circuit correlates the position information with the signal directing power to the motor so that the motor is precisely controlled for moving the latching elements between release and latch. If the motor jams (sensed by overcurrent), it is operated briefly in alternating directions to try and dislodge the grit or ice causing the jam. The padlock shackle is latched into place by balls which are driven into recesses in the shackle legs. The use of plural balls on at least one side helps isolate the drive motor and gears from grit that may enter through the padlock's top shackle holes.

Abstract: The present invention relates to an electronic lock having first and second disposed in axial alignment is provided. A first key inserted into the cylinders of the electronic lock sends an electronic signal to a solenoid which retracts a stopper from engagement with a latch plate upon turning the first key through an initial angle. Thereafter, the first key drives the first cylinder to drive a first cam which moves against a first cam follower to move the latch plate and withdraw the latch from locking engagement. In the event of an electronics failure and/or in order to manually override the electronics, a second key is inserted into the axially aligned cylinders. The second key initially drives the second cylinder to move a second cam against a second cam follower that bears against the stopper to remove the stopper from engagement with the latch plate.

Abstract: A gear driven bolt withdrawal mechanism for an electronic lock is disclosed wherein an electromagnetic device such as an electromagnetic device displaces a partial gear into a position to be engaged by a manual drive. The partial gear, in turn, drives subsequent gears in a gear train to engage a gear with teeth on a rack attached to or a part of the bolt of the lock. The restoration of the bolt is ensured by a physical engagement between a portion of the drive cam and a portion of the bolt to force the bolt to its extended position upon locking; a displaceable slide is disposed in blocking relationship to the bolt whenever the bolt is fully extended to prevent end pressure from displacing the bolt without entry of a valid combination into the electronic controls of the lock.

A latch operating solenoid is the only solenoid mechanically linked to the latch. A capacitor is supplied by a power supply and is arranged to pulse the latch operating solenoid without pulling down the power supply. The pulsing of the latch operating solenoid by the capacitor causes the latch operating solenoid to move the latch projection of the latch into and out of the latch recess of the pivot arm so that a door is locked and unlocked.

In an alternative, preferred embodiment, a tumbler lock mechanism is used, instead of the handling mechanism, and includes a double-bit key, so that both a key and a coded command are required for opening the lock.

Abstract: A locking device for a parking brake on a bus having air brakes prevents accidental release of the parking brake when a sensing switch indicates that the bus should not move (e.g., when the driver is absent from the driver's seat, or a passenger-access door is open). The locking device of the invention is affixed to a portion of the bus adjacent a parking brake air valve that has an air valve shaft moving along its axis between a fully extended position, in which the valve is in a brake-applied status, and a frilly retracted position in which the valve is in a brake-released status. The locking device has a locking arm moving between a locked position in which it prohibits the parking brake valve shaft from moving into the fully retracted position and an unlocked position in which it does not affect the motion of the valve shaft. Conventionally, the valve shaft has a knob on the end distal from the valve body, and the locking arm in the locked position, prevents the knob from being pushed in all the way.
