    Abstract: A car door hinge comprises a rotating member 2 hinged on a fixed member I by means of a hinge pin 3. One end 5 of a wire spring 4 is attached to a point on the rotating member 2 distant from the hinge pin, and the other end 8 of the wire spring 4 is attached to a point on the fixed member 1 inside a sector of a circle defined by the hinge pin 3 and an arc subtended at the hinge pin 3 which is described by the end 5 as the rotating member rotates. A spring restoring force therefore acts during the opening and closing of the door so that the door always opens and closes properly. Moreover, the spring occupies a minimum of space, and the rotation of the door is stopped at a predetermined angle.

    Abstract: A door operator of electromechanical character for utilization with swing-mounted doors is provided in a self-contained unit for mounting as a part of a door frame or for attachment to existing doors and frames. The opener has a door driving shaft mounted for rotation about a vertical axis and connectable to a door for closing and opening of the door when rotated, and a transmission interconnecting a prime mover and door driving shaft for rotation to open the door upon selective delivery of power by the prime mover. A pinion interconnected with the shaft meshes with a rack gear for shifting of the rack gear about a longitudinal axis in response to rotation of the shaft. The unit includes a module of interchangeable character having a preloaded spring and configured for the intended direction(s) of rotation of the door for opening. The spring receives energy from the rack gear upon door opening and then transfers the stored energy to the rack gear upon cessation of delivery of power by the prime mover for producing rotation of the shaft in the opposite direction to close the door while returning power to the prime mover, which is preferably an electronically driven and controlled d.c. motor. The rack gear and spring module permit rotation of the shaft also in a direction for emergency opening of the door.

    Abstract: A safety device for automatically closing a door in response to a predetermined condition, such as fire, is provided by a selectively disengageable brake operatively associated with a pivotable door closure arm. The brake includes a flexible cable wrapped around a brake drum, and means to selectively tighten the cable around the drum. A crank-pin rotates conjointly with the drum and engages the door closure arm to expeditiously close the door in the event of fire.
