Driving device, in particular for controlling a lock equipped with a cylinder insert, a rotary housing of a driving device, and a toothed ring of a driving device

An apparatus comprising:

• a key turning device, wherein the key turning device is releasably engageable with a key head of a key, wherein the key includes the key head, a key blade and a key shoulder that extends intermediate of the key head and the key blade, wherein the key blade is engageable in a key cylinder in operative connection with a lock,
• wherein the key cylinder is rotatable about an axis within a body of the lock responsive to rotation of the key, and wherein the device is operative to selectively rotatably position the key and the key engaged key cylinder, wherein the lock is changeable between a locked condition and an unlocked condition,
• the key turning device including:
• a mount ring, wherein the mount ring is releasably engageable in rotationally immovable operative connection with the body,
• wherein the mount ring includes
• an axially centered central opening, wherein the central opening is configured to enable the key head and key shoulder to pass axially therethrough,
• wherein the key shoulder is rotationally movable about the axis relative to the mount ring within the central opening,
• an internal gear ring, wherein the gear ring includes an arcuate gear segment that is axially centered and includes a plurality of radially directed gear teeth,
• a housing, wherein the housing is rotatably movably mounted in operative connection with the mount ring such that the housing is rotatable about the axis and axially immovable relative to the mount ring,
• wherein the housing includes
• an internal key pocket, wherein the key pocket extends axially within the housing and is operative to accept the key head in engaged relation within the key pocket such that the key head is rotationally immovable relative to the housing,
• an electric motor within the housing,
• a transmission within the housing, wherein the transmission
• is in operative connection with the motor, and
• includes an output gear, wherein the output gear is
• selectively rotatable responsive to the motor, and
• in meshing engagement with the teeth of the arcuate gear segment,
• at least one electric cell within the housing, wherein the at least one electric cell is in operative connection with the motor,
• wherein the motor is operative responsive to energy from the at least one electric cell to cause the key engaged lock cylinder to be rotated about the axis relative to the body of the lock and to be selectively rotatably positioned.

• wherein the key cylinder is rotatable about an axis within a body of the lock responsive to rotation of the key, and
• wherein the key turning device is operative to selectively rotationally position the key and the key engaged key cylinder, such that the lock is changeable between each of a locked condition and an unlocked condition,
• the key turning device including:
• a mount ring, wherein the mount ring is adapted to be in operatively engaged rotationally immovable connection with the body,
• wherein the mount ring includes
• an axially centered central opening, wherein the central opening is immovable relative to the mount ring and includes
• a central circular portion, and
• a rectangular ring slot, wherein the ring slot
• is axially centered and in overlapping relation with the central circular portion,
• sized to enable the key head and key shoulder to pass axially therethrough,
• wherein the key shoulder is rotationally movable about the axis relative to the mount ring within the central opening,
• an internal gear ring,
• wherein the gear ring includes an arcuate gear segment that is axially centered and includes a plurality of radially inwardly directed gear teeth,
• a housing, wherein the housing is
• rotatably movably mounted in operative connection with the mount ring,
• rotatable about the axis relative to the mount ring and is axially immovable relative to the mount ring,
• wherein the housing includes
• a key pocket, wherein the key pocket extends axially within the housing and is adapted to releasably hold the key head in engaged relation within the key pocket and rotationally immovable relative to the housing,
• an electric motor,
• a transmission, wherein the transmission
• is in operative connection with the electric motor, and
• includes an output gear, wherein the output gear is
• selectively rotatable responsive to the motor, and
• in meshing engagement with the teeth of the arcuate gear segment,
• at least one electric cell, wherein the at least one electric cell is in operative connection with the motor,
• wherein the motor is operative responsive to energy from the at least one electric cell to cause the key that is held in the key pocket and in engagement with the lock cylinder to be rotated about the axis relative to the body of the lock and to be selectively rotatably positioned to selectively cause the lock to be in each of the locked condition and the unlocked condition.
