Abstract: There is an electric motor driven drop bolt having a housing which in use is mounted into a doorway frame and has the bolt pivotal therein by a mechanical drive set in a cage disposed at an operative position. The bolt is pivotal between a locking configuration where the bolt extends outward of the housing to engage in an aperture associated with a door within the frame and an unlocked configuration where the bolt is withdrawn to clear the aperture. The mechanical drive includes a screw shaft rotatable by the electric motor to move a roller nut along the length of the shaft whilst engaging a cam surface on the bolt. To obtain fail safe operation of the drop bolt the cage is slidable in the housing from the operative position to a disengaged position so that the bolt is movable from the locking configuration to the unlocked configuration without operation of the mechanical drive.

Abstract: According to the inventive method, a pawl which in a normal mode of operation is rotatably mounted about a point of rotation when it is in a closed position can be rotated by means of a first actuator, which is controlled by a main power supply and by means of a toothed gearwheel segment which is also rotatably mounted about said point of rotation and which can run freely in relation to the pawl, until an open position is obtained. In the event of an emergency, the pawl can be rotated by means of a second self-inhibiting actuator, which is controlled by the emergency power supply, by means of another rotatably mounted toothed gearwheel segment which comprises a toothed gearwheel having a smaller diameter and which engages with the toothed wheel segment, until an open position is obtained. The emergency power supply is then interrupted and the pawl is maintained in an open position.

Abstract: Electrically-controlled and manually-actuatable lock devices are provided which can be attached in a simple manner to doors of all types. Given remodeling of existing doors, the cylinder lock present in the respective door can remain. The lock device converts a rotational motion introduced at the outside of the door by the turning of a knob, the rotational motion being conducted to the inside of the door below the lock, into a rotational motion of a cam of a cylinder lock and thus allows a traditional lock to be opened and locked. The rotational motion initiated from the outside is connected to the lock cylinder with the assistance of an electromagnetic coupling device that, in turn, actuates a mechanical coupling device. The electromagnetic coupling device is essentially designed without an air gap. This particular provision enables its operation with very low electrical energy. The lock device can therefore be supplied with electrical energy from very small batteries for years.
