Adjustable recessed door hinge

Abstract

An adjustable recessed door hinge includes a hinge cup displacably insertable in a bore of one of a frame or door member, a hinge pin mounted in the hinge cup, and a hinge arm pivoted at one end on the hinge pin and displacably securable at the other end of the hinge arm to the other of the frame or door member. The hinge cup is dimensioned to be displacable in the bore relative to the frame or door member. Slotted holes for receiving attaching screws guide displacement of the hinge cup and hinge arm relative to the frame and door members.

What is claimed is: 
     
       1. An adjustable recessed hinge for mounting a door member on a supporting frame member, one of which members is provided with a substantially circular bore having a top edge and a predetermined interior diameter, comprising: a hinge cup adapted to be inserted and .[.displaceably.]. secured in a bore of one of a frame member and a door member;   a hinge pin mounted in said hinge cup; and   a .Iadd.one-piece hinge arm having one end pivoted on said hinge pin and having an opposing end defining a hinge plate adapted to be displaceably secured to the other of said frame and door members.Iadd., wherein said hinge plate is adapted for displacement relative to said other of said frame and door members in a direction parallel to a pivot axis of said hinge arm, said hinge plate having a pair of opposing lateral edges and including portions defining a single slotted hole for receiving a single fastening screw for securing said hinge plate to said other of said frame and door members, said slotted hole being substantially centered between said lateral edges and having a longitudinal axis parallel to said pivot axis of said hinge arm for guiding said displacement of said hinge plate. .Iaddend. .[.   
     
     
       2.  A hinge according to claim 1 wherein said hinge plate is adapted for displacement relative to said other of said frame and door members in one of a direction parallel to a pivot axis of said hinge arm and a direction perpendicular to said pivot axis of said hinge arm..]. .[.3. A hinge according to claim 2 wherein said hinge cup is adapted for displacement in said bore relative to said one of said frame and door members in the other of said directions parallel to said pivot axis of said hinge arm and 
     
     
        perpendicular to said pivot axis of said hinge arm..]. .[.4.  A hinge according to claim 3 wherein said hinge plate is adapted for displacement relative to said other of said frame and door members in said direction parallel to said pivot axis of said hinge arm..]. .[.5. A hinge according to claim 4 wherein said hinge cup is configured and dimensioned to enable displacement of said hinge cup in said bore relative to said one of said frame and door members in said direction perpendicular to said pivot axis of said hinge arm..]. .[.6. A hinge according to claim 5 wherein said hinge plate includes portions defining at least one slotted hole adapted to receive a fastening screw therethrough, said slotted hole having a longitudinal axis parallel to said pivot axis of said hinge arm and adapted to guide said displacement of said hinge plate..]. .[.7. A hinge according to claim 6 wherein said hinge cup has a top edge provided with opposing side portions; and further comprising a pair of securing flanges, one extending outwardly from each of said side portions, each of said securing flanges having a slotted hole formed therein adapted to receive a fastening screw therethrough, each of said slotted holes having a longitudinal axis perpendicular to said pivot axis of said hinge arm and 
     
     
        adapted to guide said displacement of said hinge cup..]. .[.8.  A hinge according to claim 7 wherein said hinge cup has front and rear exterior walls spaced diametrically from each other a distance which is less than the interior diameter of said bore to allow said displacement of said hinge cup..]. .[.9. A hinge according to claim 8 wherein said top edge of said hinge cup has an outwardly extending circumferential flange adapted 
     
     
        to engage a top edge of said bore..]. 10. A hinge according to claim .[.9.]. .Iadd.1 .Iaddend.wherein said .[.mounting.]. .Iadd.hinge .Iaddend.plate includes portions defining a downwardly extending ledge adapted to engage said other of said door and frame members.Iadd., said ledge cooperating with said fastening screw received in said slotted hole for further securing said hinge plate to said other of said frame and door members and further guiding said displacement of said hinge plate. .Iaddend.
