Claim:
1. A self-closing and adjustable closing force cam hinge, comprising: a stationary hinge portion having a hinge body; a pivoting hinge portion having a hinge body; a hinge pin having a head and passing through a hinge pin bore of the hinge body of the stationary hinge portion and the hinge body of the pivoting hinge portion, wherein the pivoting hinge portion pivots about the hinge pin relative to the stationary hinge portion and cooperates with the stationary hinge portion to enable the pivoting hinge portion to lift as the pivoting hinge portion is rotated from a closed position to an open position and to lower as the pivoting hinge portion is rotated from the open position to the closed position; a compression spring located on the hinge so that the hinge pin passes through the compression spring and the head of the hinge pin is retracted from the compression spring to compress the compression spring so that the compression spring applies a closing force to the hinge when the hinge is in the open position; and a spring adjuster comprising an adjustably positionable body that is adjustably positionable relative to the head of the hinge pin so that 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, wherein the adjustably positionable body comprises a set screw threadably inserted into a threaded bore of the hinge body of the pivoting hinge portion, with the threaded bore located proximate the hinge pin bore of the hinge body of the pivoting hinge portion into which the head of the hinge pin is receivable.
