Abstract
A hinge is disclosed having a first leaf, a second leaf and a pin. The first leaf has a first layer and a second layer. The first leaf also has at least two hollow first leaf knuckles that are unitary with both the first layer and the second layer. The second leaf has a first layer and a second layer. The second leaf also has at least two hollow second leaf knuckles that are unitary with both the first and second layer. The pin extends through each of the knuckles to hold the leaves together.
Claims20
A hinge, comprising:
- a first leaf comprised of a first layer extending from an outer fastener flange to an inner knuckle portion in a substantially planar fashion, said outer fastener flange tapering down substantially from said inner knuckle portion outward, a second layer being substantially parallel with and located entirely against said first layer and extending to said outer fastener flange so as to substantially cover only said entire inner knuckle portion, and at least two hollow first leaf knuckles at said inner knuckle portion that are unitary with both said first layer and said second layer;
- a second leaf comprised of a first layer extending from an outer fastener flange to an inner knuckle portion in a substantially planar fashion, said outer fastener flange tapering down substantially from said inner knuckle portion outward, a second layer being substantially parallel with and located entirely against said first layer and extending to said outer fastener flange so as to substantially cover only said entire inner knuckle portion, and at least two hollow second leaf knuckles at said inner knuckle portion that are unitary with both said first layer and said second layer, wherein two threaded fasteners extend perpendicularly upward from said second layer;
- and
- a pin extending through each of said first leaf knuckles and said second leaf knuckles, said pin being enclosed entirely within said knuckles and substantially filling said knuckles;
- a stop unitary with said outer fastener flange of said second leaf, said stop extending upwardly from said first layer of said second leaf and being coplanar and spaced from said second layer of said second leaf, and configured to contact a separable roller cover;
- wherein said first leaf knuckles are axially aligned with, and alternate with, said second leaf knuckles, and
- wherein said first leaf, said second leaf and said knuckles define a surface substantially in a single horizontal plane.

A hinge, comprising:
- a first leaf comprised of a first layer extending from an outer fastener flange to an inner knuckle portion in a substantially planar fashion, a second layer being substantially parallel with said first layer and extending to said outer fastener flange, and at least two hollow first leaf knuckles at said inner knuckle portion that are unitary with both the first layer and the second layer;
- a second leaf comprised of a first layer extending from an outer fastener flange to an inner knuckle portion in a substantially planar fashion, a second layer being substantially parallel with said first layer but terminating before said outer fastener flange, and at least two hollow second leaf knuckles at said inner knuckle portion that are unitary with both the first layer and the second layer, wherein in said portion of said second leaf having overlapping first and second layers, two threaded fasteners extend from said portion in a perpendicular fashion, wherein said outer fastener flange has a unitary upwardly extending stop located between said overlapping layers and a fastener aperture in said outer fastener flange;
- a pin extending through each of said first leaf knuckles and said second leaf knuckles;
- a separable roller cover located only on said second leaf and having a semi-tubular roller housing and fastener apertures, wherein said stop extends upwardly from said first layer of said second leaf and being coplanar and spaced from said second layer of said second leaf and contact a lower surface of said cover;
- wherein said first leaf knuckles are axially aligned with, and alternate with, said second leaf knuckles.
