This invention relates to multiple configurations of devices to restrain a door or similar hinged, swinging appliance from autonomously swinging away from an initial fully or partially opened position to which it has been adjusted. No external, unattached parts are employed. The invention is applicable to any hinged, swinging object. It includes the use of either linear friction, such as through the use of compression nuts and springs applied to the hinged pin, so as to force the hinged knuckles into contact and frictional engagement. Another concept is the use of radial friction, through the application of either a slotted spring pin, or a spiral spring pin, that locates within the knuckles of the hinge components, to add friction to their pivotal movement when opening or closing of a door, or other structure.
A control hinge for stabilizing a door or other structure, and for use in inhibiting or preventing the unwanted rotation of a door or other swinging object once it has been opened or closed to an adjusted position, said hinge including a pair of face plates, each face plate having at least one integral knuckle, each knuckle having a clearance cavity provided centrally therethrough, a hinge pin locating through the cavities of the aligned hinged knuckles, and a frictional force applied to a least one said knuckle to sustain the door in its adjusted position during usage.
A control hinge for stabilizing a door or other structure, and for use in inhibiting or preventing the unwanted rotation of a door or other swinging object once it has been opened or closed to an adjusted position, said hinge including a pair of face plates, each face plate having at least one integral knuckle, each knuckle having a clearance cavity provided centrally therethrough, a hinge pin locating through the cavities of the aligned hinge knuckles, and a linear frictional force applied to at least one of said knuckles to sustain the door in its adjusted position during usage.

A hinge pin for use with a control hinge for stabilizing a door or other structure, said hinge pin having a pin length exceeding the height of the hinge, a pin head applied to the upper end of the hinge pin, said hinge pin having a threaded lower end, a calibration nut capable of threadedly engaging onto the lower end of the hinge pin, and tightened to provide an interknuckular force between the knuckles of the hinge plates formed of the control hinge.
A hinge pin for use with a control hinge for stabilizing a door or other structure, said hinge pin comprising a length of spring, having a slot therein, and provided for exertion of a radial frictional force against the hinge knuckle to hold any door at its adjusted position during usage.
A hinge pin for use with a control hinge for stabilizing a door, wherein said hinge pin is a spiral spring, said spiral spring exerting pressure against one of the hinge knuckles to sustain the operative door at its adjusted position during usage.
A hinge pin for use with a control hinge for stabilizing a door or other structure, said hinge pin having a pin length exceeding the height of the hinge, a pinhead applied to the upper end of the hinge pin, said hinge pin having a threaded lower end, a calibrating nut capable of threadedly engaging onto the lower end of the hinge pin, and tightened to provide an interknuckular frictional torque force between the knuckles of the hinge plate formed of the control hinge, the torque frictional force being established at that force necessary to hold the door at its adjusted position during usage, and said torque frictional force being determined through the formulation:
