US 4,045,715 A · Operator motor control

Abstract

Control system including radio receiver circuit for a power-driven operator for garage doors and the like comprising an operator control circuit having a regulated DC voltage source operating as a power supply for an electronic flip-flop device responsive to successively applied input signals to establish circuits of opposite direction through a reversible electric motor; i.e., one actuation causes the motor to run in one direction and the next actuation causes it to run in the opposite direction. The operator is subject to actuation by both a hard-wired push-button and a radio receiver which is responsive to signals from a remote transmitter. The power supply for the flip-flop is also the power supply for the receiver; however, the receiver is packaged separately from the operator and power supply and is readily disconnected for independent maintenance and repair.

Dependent claims

A selectively operable reversible power drive for closures which are movable between first and second limits of travel comprising;

a reversible motive power source, first and second switch means for establishing first and second excitation circuits to said motive power source for causing operation thereof in respectively opposite directions, an electronic bistable circuit device having first and second output stages and responsive to successive applications of an input signal to alternately energize said stages, means operatively interconnecting said first and second stages with said first and second switch means, respectively, thereby to complementally control the conditions of said first and second switch means according to the energization of said stages, a regulated DC voltage source interconnected with said bistable electronic device, and selectively actuable signal generating means connected to the bistable circuit device for applying an input signal thereto with each actuation thereof.
