Abstract:
The invention relates to an automatic remote controlled opening device which may be used to open and close doors, windows or similar closure systems. The opening device includes a receiver to detect control signals generated at a remote location from the device. The control signals are then utilized to effect selective operation of a mechanical system coupled with the closure system for opening and closing thereof. The mechanical system enables smooth and efficient automatic opening and closing, but does not inhibit manual operation of the door or the like. Control circuitry associated with the device enables various functions to be performed for selective operation of the device. The device may also be provided with a stored energy source of power such that it can be retrofit for use with an existing closure system. Auxiliary control of the device enables opening or closing in response to an emergency situation or other circumstances.
