Abstract
A butt mounted riser hinge has a plastic cam assembly mounted in two metallic cylinders so that their camming surfaces do not rub against the metallic cylinders and become readily worn. The cam assembly includes a male member with bevelled end that is rotatably received in a cup-shaped female member. The hinge further includes a spring and shell assembly in sliding arrangement with one of the metallic cylinders.
