Abstract
A springless self-latching hinge is provided having a pair of hinge members pivotally connected by a hinge pin and formed of resilient material configured to snap the hinge closed and to releasably maintain the hinged closed. The first hinge member includes a pair of raised, spaced hinge pin receiving knuckles and a boss protruding toward the pin. The second hinge member has a hinge knuckle incompletely encircling the pin and forming a bearing sleeve. A portion of the bearing sleeve forms an exterior, concave cam which is compressed against the boss as the hinge is operated. The compression between the boss and the sleeve is a maximum just prior to closure of the hinge and is maintained at less than maximum when the hinge is fully closed. The hinge thus snaps closed after partial closure and is held releasably closed until sufficient effort is exerted to rotatably open the hinge against the force of the resilient members.
