A hinge construction includes a hinge bracket that includes a hinge pin supporting plate and at least one opening extending through the hinge pin supporting plate. Also included in the hinge construction is a hinge pin that is held at the at least one opening. The hinge pin includes a hinge pin outer surface, a hinge pin bore extending through the entire length of the hinge pin and a hinge pin slot extending along the entire length of the hinge pin from the hinge pin outer surface to within the hinge pin bore. The at least one opening can be tapered, and the hinge pin outer surface can include a hinge pin outer surface first portion that also is tapered so as to be congruent with the at least one tapered opening. The hinge construction allows elements such as electrical wiring to be routed through the hinge construction.
