Interlocking hinges are attached to printed circuit boards and coupled together to form a stack of printed circuit boards. Access to each board is possible by rotating the stack at a selected hinge to expose a selected board. A projection and an opening on each hinge mate with openings and projections on other hinges to allow easy removal or addition of a board from the stack when the hinges are in one relative position, but to create an interference fit in a second relative position, thereby causing the hinges to lock together and form a rigid structure.

An interlocking hinge comprising: a body; a projection extending perpendicular to the longitudinal axis and adjacent to a first longitudinal end of said body, said projection having one or more eccentric portions with respect to the central axis thereof; engaging means adjacent to a second longitudinal end of said body for freely engaging an object of a shape corresponding to that of said projection in one relative position and for locking together therewith in a second relative position; and attachment means connected to the body of said hinge for attaching an external member thereto, said attachment means comprising two lateral extensions from said body, said lateral extensions having force-fitting means interposed therebetween for force-fitting into an opening in said external member.
