Abstract: A device (10) for closing swinging doors of the type utilizing a rotating member to compress a spring (40) during door opening to store energy in the spring (40) to effect a closing of the door is provided with a driving connection to a d.c motor/generator (62) effective to cause rotation of the motor during a closing movement of the door. The motor/generator (62) acts as a generator during the closing with the generated electrical energy fed back to the motor/generator (62) to retard rotation of the rotor, providing a brake on the closing movement of the door. The feedback circuitry includes a switch (82) disabling or diminishing the braking during the final degrees of closing movement as well as a variable setting device (80) allowing control of braking force.

Abstract: A device for controlling swinging doors utilizing an externally powered motor (62) to compress a spring (40) during door opening to store energy in the spring (40). The motor (62) is not used to open the door, but only to compress the spring (40), thereby utilizing a minimum amount of electrical energy and allowing for a very easy opening of the door. The motor (62) acts as a generator during the closing of the door with the generated electrical energy fed back to the motor (62) to retard rotation of the rotor, providing a brake on the closing movement of the door. The feedback circuitry includes a switch for varying the braking during the final degrees of closing movement as well as a variable setting device allowing control of braking force.
