ABSTRACT:
A hinge pin including two substantially identical sections which when assembled form a cylindrical sleeve. Each section has a first end having a cross-section greater than a semi-circle which tapers along its length to a second end having a cross-section less than a semi-circle. When the two sections are joined together, they form a cylindrical sleeve for use as a readily removable hinge pin. Ready removal is effectuated by sliding one section away from the other along their tapered lengths, the taper enabling the average diameter of the sleeve to decrease as the two sections are so slid apart.
