A lock release control device for an opening and closing body configured to control an opening and closing body that opens and closes an opening portion of a vehicle. The opening and closing body comes into contact with a sealing member provided on a vehicle body side of the vehicle in a fully closed state. The vehicle includes a locking device and an opening and closing actuator. The locking device restrains the opening and closing body in a fully closed position. The opening and closing actuator displaces the opening and closing body by rotation of a motor to change the opening and closing body from one of two states including an open state and a closed state to another of the states. The lock release control device is configured to execute an open command acquisition process, a pull-in process, and a lock release process.

A control and drive assembly for a transport vehicle door, and which includes a main control unit; a main motor to drive the door leaves and which is controlled by the main control unit to displace the leaves; an auxiliary control module; an auxiliary motor operable to: control the auxiliary motor so as to displace the leaves in at least one direction to a closed position, control a locking of the leaves in the closed position; and a connection device arranged between the main control unit and the auxiliary motor to facilitate transmission of a reference signal by the main control unit to the auxiliary control module, the reference signal being representative of a proper operating state of the main motor and the main control unit. The auxiliary control module is operable to actuate the auxiliary motor when the auxiliary control module does not receive the reference signal.

The motorized drive according to the application is particularly suitable for auxiliary or emergency drives and is configured to open or close a wing of a barrier such as a door. The motorized drive includes a motor and a reduction unit through which the motor can open or close the wing, an auxiliary motor including a helical spring which is able to absorb mechanical energy during the opening of the wing and release it during the closing of the same, a reduction unit connecting the auxiliary motor to the wing. A first and a second toothed profile realize a gear with a variable transmission ratio. The first and/or the second toothed profile form at least one toothing having a pitch profile which is substantially non-circular or not formed by a simple arc of a circle or a straight line.

The invention relates to a device for releasing and resetting a fire and smoke barrier. In a normal use state, a clutch member is held by an electromagnetic attraction unit, so that a push rod ejecting module cannot be actuated, and a door operator is controlled by a clutch module thereof. Upon power failure, for example upon an accident, the clutch member is released by the electromagnetic attraction unit, and a barrier release member is activated by the push rod ejecting module so as to shut the fire and smoke barrier. Upon power restoration, the clutch member is attracted and held by the electromagnetic attraction unit, and the push rod ejecting module is reset by a push rod resetting module. At the same time, the barrier release member is also reset.
