Abstract: A hinge includes a hinge body, a self-close mechanism disposed within the hinge body, and a slow-close mechanism disposed within the hinge body. The hinge body has a first portion and a second portion, the first portion is rotatable with respect to the second portion between an open position and a closed position. The self-close mechanism applies a closing force on the first portion from a first angle of rotation between the first portion and the second portion to the closed position, the closing force urging the first portion to the closed position. The slow-close mechanism applies a damping force on the first portion from a second angle of rotation between the first portion and the second portion to the closed position, the damping force slowing a rotational speed of the first portion to the closed position.

A clip is designed to be a part of the assembly, hold the parts of the assembly in desired rotational relationship, and ensure that the assembly is mounted in proper rotational position.

Abstract: One leaf of a spring hinge has a center knuckle and the other leaf has aligned top and bottom end knuckles which are spaced apart. The center knuckle of the one leaf fits between the two end knuckles of the other leaf and is maintained in alignment with them by top and bottom hinge pins, the former extending from the top knuckle into the center knuckle and the latter from the bottom knuckle into the center knuckle. Whereas the bottom pin is attached to the center knuckle, the top pin is attached to the top knuckle, but its angular position is easily changed. Each pin has a threaded portion that is located within the center knuckle, and the end convolutions on a coil-type torsion spring are threaded over these threaded portions to secure the spring to the hinge pins. Each hinge pin also has a shank which extends from its threaded portion through the interior of the spring where the ends of the two shanks abut.
