Abstract
Abstract This hinge assembly includes a base having a lid attached thereto by means of a pair of articulating hinges which permit the lid to be swung about the base and also to be raised relative to the base. Each hinge consists of a slotted hinge element attached to the base and a second hinge element attached to the lid. Associated elements of each pair of hinges are interconnected by a pin which is slidably received within the slot of the slotted hinge elements. One of the hinge elements of each pair includes a pair of shoulders and the other includes a pair of associated abutment lugs. One of the shoulders engages one of the abutment lugs to hold the lid in a spaced horizontal position and the other shoulder engages the other lug to hold the lid in a vertical position. A bell crank element, pivotally attached to the slotted hinge element, provides a notched latch supporting the pin and predetermining the space between the lid and the base.
