Abstract
Abstract A hidden hinge construction for use in hingedly fastening one member to another member includes first and second parts which are adapted to be countersunk into the members. Each of the parts has appended thereto a plate which is respectively adapted to be fastened to the member. One of the hinge parts includes a projecting pin, and to the other hinge part includes an axial opening for rotatively receiving the pin.

A hinge for hingedly fastening a first member to a second member permitting relative rotation therebetween about an axis of rotation, said first and second member respectively including first and second contiguous, overlapping parallel planar surfaces orthogonal to said axis of rotation, each of said surfaces having an edge orthogonal to said axis of rotation, said hinge comprising a first part including a first plate member adapted to be fastened to said first planar surface of said first member, and a first arm member attached to said first plate member and extending substantially normally thereto and outwardly therefrom, an opening being formed near the outwardly extending end of said arm member; said opening being aligned with said axis of rotation; and a second part including a second plate adapted to be fastened to said second planar surface of said second member, a second arm member attached to said second plate and extending substantially perpendicularly thereto and outwardly therefrom and a pin extending upwardly from the outwardly extending end of said arm member and adapted to be rotatively received in said opening, said opening in said first part, said pin of said second part and said axis of rotation being disposed within the area of said overlap and substantially at said edges.
