A motor that is capable of both linear and rotational motion. One coil translates the motor along its axis for linear motion and a second coil causes the shaft to rotate. Coacting with the translate coil is a translate magnet where the north and south poles are oriented along the motor shaft. A segmented magnet where alternating north and south poles are located along the periphery of the magnet interacts with a rotation coil so that the interaction of the magnetic field of the segmented magnet and the magnetic field produced by the rotation coil cause the rotary magnet to rotate. Rotation of the rotary magnet, which cooperates with the shaft to which it is operably connected, causes rotation of the motor shaft.

Motor with linear and rotary motion

A self powered lock is powered by a manually driven generator. The data input to the lock is entered by rotating the dial and stopping and waiting a predetermined amount of time when a desired number is displayed on the lock display. The drive of the power generator, a stepper motor, is through a unidirectional clutch, such that the generator is only driven when the dial is rotated in a selected direction and remains stationary when the dial is rotated in the opposite direction. The data input, including entry of the combination, to the lock is provided by a stepper motor which generates a train of electrical pulses. The electrical pulses are used by the electronic controls of the lock to control the electronic controls including entering the combination. The data input pulses are generated by a stepper motor driven to act as a generator. The data input generator is similarly driven through a unidirectional clutch and is driven only when the dial is being rotated in a direction opposite the direction in which the power generator is driven. Accordingly, only the power generator or the data input generator is driven at any one time, depending upon the direction of rotation of the dial. A third unidirectional clutch is used to grasp the shaft of the data input stepper motor, preventing the reverse rotation of the rotor when the dial of the lock is rotated to generate operating power.

A mechanism for locking the back cover of a combination lock to the lock housing is described having two sequentially and phased moveable parts, each having an aperture through which a locking member may be inserted, the apertures are disposed in parts moveable in parallel and adjacent planes and a portion of each aperture is at all times aligned with the other aperture such that a third member may extend through the apertures. The apertures have enlarged portions which will pass the third member and channel portions which prevent withdrawal of the third member while permitting movement of the moveable parts. The third member is carried by the back cover of the lock and can only be withdrawn by sequentially withdrawing from a first moveable part, shifting the moveable parts to a second position and withdrawing from the second moveable part. The back cover may thus be only removed by starting with the bolt in an extended position and locked condition and prior to final withdrawal of the third member, withdrawing the lock bolt to an unlocked position, necessitating possession of authorization to unlock the lock in order to remove the back cover.

Back cover lock for a combination lock

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.
