ABSTRACT:
There is disclosed a spring hinge comprised of a pair of hinge leaves each having at least one tubular hinge knuckle, the knuckles being in axial alignment to define a bore, a torsion spring member extending axially through the knuckle bore and having its opposite ends affixed to a pair of capstan members for rotation in unison therewith. The first capstan member is non-rotatably mounted within one of the hinge knuckles, while the second capstan member is rotatably mounted within the other hinge knuckle. The second capstan member includes a plurality of circumferentially spaced sockets selectively movable into registry with a through aperture in the associated hinge knuckle, such that a retaining pin member may be inserted therein. The pin member holds the capstan in a desired radial position to impart a desired degree of torsional force or tension to the spring member. The pin member has first and second portions of different diameters thereby defining a shoulder portion. The torsion spring tends to rotate the capstan so as to hold at least a pair of the shoulder portion out of registry with the hinge aperture to substantially preclude axial removal of the pin member therethrough due to vibration or the like. The pin member also has an enlarged, severable head portion to facilitate its insertion, which head portion can be fractured and removed following the insertion.
