Adjustable hinge
View Patent ↗The hinge has a bracket for mounting on a door frame, an adjusting plate for securement to a door, a flange pivotally mounted on the bracket and disposed over the adjusting plate and captive nut assemblies for securing the flange to the adjusting plate in a releasable longitudinally adjustable manner. Loosening of the captive nut assemblies allows the door to be moved laterally of the frame before tightening of the captive nut assemblies fixes the door relative to the frame.

means for securing said flange to said adjusting plate in releasable manner to allow manual adjustment of said flange relative to said adjusting plate without removal of said flange from said adjusting plate wherein said adjusting plate has a plurality of elongated slots disposed longitudinally of said plate and in parallel relation to each other, said flange has a plurality of bores in alignment with said slots of said adjusting plate and said means includes a plurality of captive nut assemblies, each said captive nut assembly having a nut slidably disposed in a respective one of said slots of said plate and a screw passing through a respective bore of said flange and threadably mounted in said nut.
2. An adjustable hinge as set forth in claim 1 further comprising a cover plate removably mounted on said flange on a side opposite said adjusting plate.
3. An adjustable hinge comprising
a bracket for mounting on a door frame;
a flange pivotally mounted on said bracket for mounting on a door;
an adjusting plate having a plurality of bores for passage of mounting elements therethrough into a door;
means for securing said flange to said adjusting plate in releasable manner to allow manual adjustment of said flange relative to said adjusting plate without removal of said flange from said adjusting plate; and
a cam assembly mounting said flange on said bracket, said cam assembly including a female cam mounted in said bracket and having a cylindrical bore and a pin secured to said flange and rotatably mounted in said bore of said female cam.
4. An adjustable hinge as set forth in claim 3 wherein said cam is of oval cross-section with a plurality of longitudinal grooves and ribs extending about a part periphery thereof.
5. An adjustable hinge as set forth in claim 4 wherein said cam has a central cylindrical section with said ribs extending outwardly of said central cylindrical section.
6. An adjustable hinge as set forth in claim 5 wherein said ribs are trapezoidal in cross-section.
7. An adjustable hinge as set forth in claim 3 wherein said flange has a hub receiving said pin of said cam assembly in non-rotatable manner and having a predetermined offset from the remainder of said flange.
8. An adjustable hinge as set forth in claim 7 wherein said pin is of plastic material and has a radially extending collar abutting each of said hub and said cam in slide relation.
9. In combination
a door frame;
a door disposed within said frame for moving between a closed position and an open position relative to said frame; and
at least one adjustable hinge securing said door to said frame for pivoting of said door between said closed position and said open position, said hinge including a bracket mounted on said door frame, an adjusting plate secured to said door, a flange pivotally mounted on said bracket and disposed over said plate and means for securing said flange to said adjusting plate in releasable manner to allow manual adjustment of said door relative to said door frame without removal of said flange from said adjusting plate wherein said adjusting plate has a plurality of elongated slots disposed in parallel relation to each other, said flange has a plurality of bores in alignment with said slots of said adjusting plate and said means includes a plurality of captive nut assemblies, each said captive nut assembly having a nut slidably disposed in a respective one of said slots of said plate and a screw passing through a respective bore of said flange and threadably mounted in said nut for securing said flange to said adjusting plate.
10. The combination as set forth in claim 9 further comprising a cover plate removably mounted on said flange on a side opposite said adjusting plate.
11. In combination
a door frame;
a door disposed within said frame for moving between a closed position and an open position relative to said frame;
at least one adjustable hinge securing said door to said frame for pivoting of said door between said closed position and said open position, said hinge including a bracket mounted on said door frame, an adjusting plate secured to said door, a flange pivotally mounted on said bracket and disposed over said plate and means for securing said flange to said adjusting plate in releasable manner to allow manual adjustment of said door relative to said door frame without removal of said flange from said adjusting plate; and
a cam assembly mounting said flange on said bracket, said cam assembly including a female cam mounted in said bracket and having a cylindrical bore and a pin secured to said flange and rotatably mounted in said bore of said female cam.
12. The combination as set forth in claim 11 wherein said cam is of oval cross-section with a plurality of longitudinal grooves and ribs extending about a part periphery thereof.
13. The combination as set forth in claim 11 wherein said flange has a hub receiving said pin of said cam assembly in non-rotatable manner and having a predetermined offset from the remainder of said flange.
14. The combination as set forth in claim 11 wherein said pin is of plastic material and has a radially extending collar abutting each of said hub and said cam in slide relation.
15. An adjustable hinge comprising
a bracket for mounting on a door frame;
a flange pivotally mounted on said bracket for mounting on a door;
an adjusting plate having a plurality of bores for passage of mounting elements therethrough into a door; and
means for securing said flange to said adjusting plate in releasable manner to allow manual adjustment of said flange relative to said adjusting plate without removal of said flange from said adjusting plate wherein said means includes a plurality of captive nut assemblies, each said captive nut assembly having a nut passing through said plate and a screw passing through said flange and threadably mounted in said nut.
16. An adjustable hinge as set forth in claim 15 wherein said adjusting plate has a plurality of elongated slots, each said slot receiving a nut of a respective captive nut assembly.
