  • Publication number: 20070075665
    Abstract: An operating device for an overhead closure which comprises a motor, operatively connected to the closure for opening and closing the closure, and at least one sensor unit mountable either the closure or a support surface bordering the closure. The sensor unit is operable to detect the presence of an obstacle obstructing a travel path of the closure and to generate a signal in response thereto. A control system is in communication with the sensor and with the motor. The control system includes a control unit which receives the signal and provides a sensing feature which stops and/or opens the closure in response to the signal. The control unit deactivates the sensing feature at a selected point prior to an end limit position of the closure. The selected point is determined by the control unit based on a calculated delay characteristic.

  • Publication number: 20040211279
    Abstract: An auxiliary operating device for manually operating a normally motor-operated closure between open and closed positions, the device comprising a shaft, a driving member mounted to the shaft and displaceable between an idle position and an operational position wherein the driving member is operatively coupled to the closure. The device further comprises a manual actuator for first displacing the driving member from its idle position to its operational position and then driving the driving member in order to displace the closure. The actuator can be advantageously mounted at either end portions of the shaft irrespectively of the position of the driving member on the shaft.
