Abstract
A hinge assembly has a hinge door that is pivotally mounted to a hinge base. The door has a flat body with a pair of square tabs extending laterally from one end. The hinge base has a flat frame with a rectangular aperture. A pair of parallel, rigid flanges extend from the aperture in the frame. Each flange has an entry hole that leads into a diagonal slot. The slots terminate in circular recesses. The hinge door is installed in the hinge base to form the assembly by initially positioning the tabbed end of the door diagonally in the aperture. The tabs are then elevated slightly above the frame and rotated into alignment with the entry holes. The door is angled into alignment with the diagonal slots and lowered in that plane. This motion causes the tabs to move past the entry holes, through the slots, and into the circular recesses to form the hinge assembly. The recesses closely receive the tabs on the door to allow pivotal motion therebetween.
