The preferred embodiment includes a hole in the top of the hinge pin which is extended to a groove or channel on the outer surface of the pin. The groove can extend in a spiral downward slope to the bottom of the pin. In other embodiments the hinge pieces and not the hinge pin are created with a path for lubricant to reach the space between the hinge pieces and pin. A channel can be included on the inner surface of the hinge pieces to ensure better distribution of the lubricant.
