Abstract
A self closing and adjustable closing force cam hinge includes a compression spring located on the hinge so that a hinge pin passes through the compression spring and the head of the hinge pin is retracted in a direction away from the compression spring to compress the compression spring. Compression of the spring applies a closing force to the hinge when the hinge is in the open position. The hinge also includes a spring adjuster having an adjustably positionable body that is adjustably positionable relative to the head of the hinge pin. Adjustment of the position of the adjustably positionable body raises or lowers the head of the hinge pin such that raising of the hinge pin increases compression of the compression spring to increase the closing force applied by the compression spring and lowering of the hinge decreases compression of the compression spring to decrease the closing force applied by the compression spring.
