Abstract: A pivot hinge includes a spring housing with a central tube, a spring assembly, an upper mounting plate, and a lower mounting plate. The bottom end includes a knurled outer surface. A stop cam is positioned about the knurled outer surface and has an inner surface that conform to the knurled outer surface so that it may be positioned in a plurality of rotatable positions relative to the central tube. The stop cam also has an exterior surface which includes a detent. The different rotational positions of the stop cam upon the knurled outer surface changes the relative position of the detent in relationship to the central tube. A cam follower assembly is coupled to the lower mounting plate and has a cam follower plate with a cam follower that rides upon the stop cam and engages the detent recess to hold the door in an open position.

Abstract: A magnetic latch (10) for an appliance is disclosed for use with a strike plate (12). The latch includes a body (16) having two oppositely disposed side walls (18) and a bottom surface or wall (20). The body defines a magnet recess (26). An elongated handle (40) is pivotally coupled to the body. A spring loaded plunger pin (34) biases the handle. A magnet assembly (44) is positioned within the body. The magnet assembly includes a magnet (46) having a peripheral edge (48), and a pair of metal plates (54). The magnet has a peripheral cushioning sleeve (58) extending about the peripheral edges of the magnet. The peripheral sleeve is generally rectangular in shape having two oppositely disposed end walls (60) which include a cushioning projection (68). A pivot pin (74) extends through the magnet assembly to allow rocking motion.

Abstract: A pivot hinge includes a spring housing with a central tube, a spring assembly, an upper mounting plate, and a lower mounting plate. A pivot pin is positioned within the central tube and is coupled to a torsion spring. A top end of the pivot pin is received within a central channel of a spring bushing. The spring bushing has a cylindrical main portion and a undulating ridge forming three radially positioned high areas or tongues and three radially positioned low areas, troughs or grooves. The grooves are configured to receive or mesh with interior steps in the central tube to prevent relative rotation between the spring bushing and the central tube Each tongue also includes a spring mounting recess therein. The top end of the cylindrical main portion extends through and is journalled within the top opening of the central tube.
