Abstract
The hidden interlocking hinge assembly at least partially hides or conceals the hinging mechanism of a door pivotally attached to a jamb. The assembly incorporates interlocking knuckles on the door and the jamb, an overlapping flange feature, and a corresponding depression feature that allows the overlapping flange and the depression to move relative to the other without binding and while generally concealing the balance of the assembly.
Claims11
A hidden interlocking hinge assembly comprising:
- a jamb including an inner jamb plastic layer and an outer jamb plastic layer selectively fused to form a jamb knuckle integrally formed with the jamb, the jamb knuckle forms a seam whereat the inner jamb plastic layer and the outer jamb plastic layer are fused and a barrel whereat the inner jamb plastic layer and the outer jamb plastic layer are spaced apart;
- a jamb hinge pin opening formed through at least one of the seam and the inner jamb plastic layer of the barrel;
- a door including an inner door plastic layer and an outer door plastic layer selectively fused to form a door knuckle integrally formed with the door;
- a door hinge pin opening formed only through the inner door plastic layer;
- a depression integrally formed with one of the jamb and the door;
- and
- a flange integrally formed with and extending from the other of the jamb and the door;
- wherein the door knuckle and the jamb knuckle are configured to interlock along a hinge axis that is coaxial with the jamb hinge pin opening and the door hinge pin opening;
- wherein the flange extends beyond the hinge axis;
- and
- wherein pivoting the door about the hinge axis pivots the flange into the depression.

A hidden interlocking hinge assembly comprising:
- a door formed from an inner door plastic layer and an outer door plastic layer selectively fused;
- a plurality of door knuckles formed from at least one of the inner door plastic layer and the outer door plastic layer;
- a plurality of door hinge pin openings formed only through the inner door plastic layer;
- a flange formed from at least one of the inner door plastic layer and the outer door plastic layer;
- a jamb formed from an inner jamb plastic layer and an outer jamb plastic layer selectively fused;
- a plurality of jamb knuckles formed from the jamb inner plastic layer and the jamb outer plastic layer defining fused seams and spaced apart barrels;
- a plurality of jamb hinge pin openings formed through the inner jamb plastic layer and the outer jamb plastic layer at the fused seams and the spaced apart barrels;
- a recess formed from the outer jamb plastic layer;
- and
- a hinge pin extending through the plurality of door hinge pin openings and the plurality of jamb hinge pin openings to link the door knuckles and the hinge knuckles such that the door is pivotable between a closed position and an opened position;
- wherein the recess is sized to receive at least a portion of the flange when the door is pivoted from the closed position to the opened position.
