    Abstract: An improved two knuckle hinge comprises a pair of adjacent hinge leaves on which long and short axially aligned hinge knuckles are formed. The long hinge knuckle houses a bushing in its end adjacent the short hinge knuckle to act as an anti-friction bearing. A torsion spring may also be housed in the portion of the long hinge knuckle unoccupied by the bushing for urging the leaves together. A pintle, about which the long hinge knuckle pivots, is supported in the short hinge knuckle and extends into and cooperates with the torsion spring, when the torsion spring is present in the long knuckle. Also disclosed is a two knuckle hinge that simulates the appearance of a three or more knuckle hinge. This is accomplished through the use of one or more markings such as grooves in the long hinge knuckle which simulate the appearance of gaps between knuckles.

    Abstract: A controlled release door holder comprises a housing having a portion defining a cylinder for containment of a fluid, a piston received in the cylinder for movement axially thereof and dividing the cylinder into first and second chambers, and a linkage between the piston and the door for moving the piston in the cylinder as a function of door movement. A spring compressed between the piston and housing biases the door toward the closed position. Three hydraulic paths communicate the sections of the cylinder on either side of the piston: the first path includes a check valve that allows one-way flow from the spring side to the other side as the door is opened; a second path, which includes a pressure relief valve, allows flow from the other side to the spring side when the door is pushed closed, but resists the spring pressure and holds the door in any desired position; a controllable valve responds to control signals to shunt the fluid pressure generated by the spring in the other side of the cylinder to the spring side so that the spring force acting on the piston moves the door, by force transmission through the linkage, toward closed position.

    Abstract: A low friction, long life concealed bearing hinge has plastic bushings inserted in the abutting ends of adjacent hinge knuckles. A hinge pin through the bushings results in a radial bearing surface between the hinge pin and the hinge bushing. The smooth outside faces on adjacent axially abutting bushings provide a thrust bearing between adjacent knuckles. The plastic materials are selected to interact mutually and with the hinge pin in a favorable way to retard wear.
