Abstract
A recessed hinge is disclosed that allows a door to open to an angle greater than 90 degrees. The hinge has a hinge pin with two free ends so that the hinge is also fully reversible, for use either on the right hand or left of an enclosure. The hinge also provides for simplified horizontal adjustment by having oval mounting holes for attaching the hinge to the enclosure, and the hinge provides for vertical adjustment by disposing one or more washers on the free end of the hinge pin. Vertical adjustment of the door as well as door removal may be accomplished without tools.
Claims16
A reversible hinge for mounting a removable door on an enclosure, the enclosure having either a left door post or a right door post, the reversible hinge comprising:
- a) a hinge pin assembly comprising a door post mounting flange for mounting to either door post, a hinge pin retainer, and a hinge pin, the hinge pin having a first free end and a second free end, the first free end being oriented in an upward direction when the door post mounting flange is mounted to the left door post, the second free end being oriented in the upward direction when the door post mounting flange is mounted to the right door post;
- and
- b) a hinge receptacle assembly comprising a door mounting flange and a cylindrical hinge receptacle;
- wherein the cylindrical hinge receptacle is disposed about the free end of the hinge pin oriented in the upward direction when mounting the removable door on the enclosure such that the hinge receptacle assembly is transitionally fixed relative to the hinge pin assembly, but freely rotatable about a common axis of the hinge pin and the cylindrical hinge receptacle to effect opening and closing of the removable door.
A reversible hinge for mounting a removable door on an enclosure, the enclosure having either a left door post or a right door post, the reversible hinge comprising:
- a) a hinge pin assembly comprising a door post mounting flange for mounting to either door post, a hinge pin retainer, and a hinge pin, the hinge pin having a first free end and a second free end, the first free end being oriented in an upward direction for a left hand mounted door and the second free end being oriented in the upward direction for a right hand mounted door;
- and
- b) a hinge receptacle assembly comprising a door mounting flange and a cylindrical hinge receptacle, the cylindrical hinge receptacle having a circular opening at each of a first end and second end of the cylindrical hinge receptacle, the circular opening at the first end being disposed about the first free end of the hinge pin for the left hand mounted door, and the circular opening at the second end being disposed about the second free end of the hinge pin for the right hand mounted door;
- wherein the cylindrical hinge receptacle is disposed about the hinge pin such that the hinge receptacle assembly is translationally fixed relative to the hinge pin assembly, but freely rotatable about a common axis of the hinge pin and the cylindrical hinge receptacle to effect opening and closing of the removable door.
An adjustable hinge for mounting a door on a door post comprising:
- a) a hinge pin assembly comprising a door post mounting flange, a hinge pin retainer, a hinge pin, and a first mounting hole drilled in a first end of the door post mounting flange and a second mounting hole drilled in a second end of the door post mounting flange, the mounting holes being substantially oval in shape, horizontal adjustment of the door being accomplished by horizontal translation of the hinge pin assembly relative to the door post;
- and
- b) a hinge receptacle assembly comprising a door mounting flange and a cylindrical hinge receptacle, vertical placement of the door being adjusted by disposing one or more washers about the hinge pin, the hinge receptacle assembly resting on the one or more washers rather than the hinge pin retainer,
- wherein the cylindrical hinge receptacle is disposed about the hinge pin such that the hinge receptacle assembly is translationally fixed relative to the hinge pin assembly, but freely rotatable about a common axis of the hinge pin and the cylindrical hinge receptacle to effect opening and closing of the door.
