ABSTRACT:
A door hinge and hold-open apparatus incorporates a torsion bar structure, having detent and torsional portions, carried by a first hinge member. A striker is carried by a second hinge member in alignment with the detent portion of the torsion bar structure for engaging the detent portion upon movement of the second hinge member, relative to the first hinge member, through a predetermined positional range. A torsional section of the torsion bar structure extends along an elongated body of one of the hinge members, and load carrying portions of the torsion bar structure which bear against the elongated hinge body are spaced from a mid-section of the hinge body at which the body is attached to a door or support structure. The apparatus is particularly adapted for use in a hinge having body portions of nonmetallic, composite construction having reinforcing fibers extending longitudinally of the hinge body.
