Abstract
Abstract A hinge structure for refuse containers having a body and a top opening and a lid for the opening, in which the lid is attached to the body by a hinge structure having a torque bar therein for assisting in the opening of the lid. The torque bar runs along the back of the lid and has laterally extending ends which engage abutments on the body to apply torque to cause the bar to exert a lifting force to the lid. The ends disengage the abutments after the lid has been opened to a predetermined point so that the lid can be easily and fully opened without the torque bar interfering with the full opening of the lid. The lid can be easily lifted to empty refuse into the container and will fully reclose itself notwithstanding the restraining effect of the torque bar.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
231 words
A hinge structure for refuse containers having a body with a top opening and a lid for the opening: said hinge structure comprising a fixture disposed at each end at the upper rear corners of the body and having a hole therethrough, a torque bar means extending along the rear side of the lid and extending through the holes in said fixtures, finger means attached to each end of the torque bar means and extending substantially at right angles thereto, spaced pivot means attached to said lid near said fixtures and being rotatable on said bar means as said lid is opened and closed, means disposed between said spaced pivot means for preventing relative rotation between the lid and said bar means in a section spaced from said pivot means, an abutment on said body at each end of said bar means forming a stop for said fingers to limit the rotation of the end sections of said bar means and thereby causing said bar means to apply a force tending to open said lid, said abutments being mounted rigidly on said body adjacent the rear edge thereof and so disposed relative to said fingers that said fingers move away from said abutments when the lid is partially opened, such that said bar means assists only the initial opening of the lid and resists only the final closing of said lid.
Claim 2
Dependent Claim
231 words
A hinge structure for refuse containers having a body with a top opening and a lid for the opening: said hinge structure comprising a fixture disposed at each end at the upper rear corners of the body and having a hole therethrough, a torque bar means extending along the rear side of the lid and extending through the holes in said fixtures, finger means attached to each end of the torque bar means and extending substantially at right angles thereto, spaced pivot means attached to said lid near said fixtures and being rotatable on said bar means as said lid is opened and closed, means disposed between said spaced pivot means for preventing relative rotation between the lid and said bar means in a section spaced from said pivot means, an abutment on said body at each end of said bar means forming a stop for said fingers to limit the rotation of the end sections of said bar means and thereby causing said bar means to apply a force tending to open said lid, said abutments being mounted rigidly on said body adjacent the rear edge thereof and so disposed relative to said fingers that said fingers move away from said abutments when the lid is partially opened, such that said bar means assists only the initial opening of the lid and resists only the final closing of said lid.
Claim 3
Dependent Claim
34 words
A hinge structure for refuse containers as defined in claim 1 in which said lid has a U-shaped flange along the rear edge thereof and said torque bar means is disposed in said flange.
Claim 4
Dependent Claim
39 words
A hinge structure for refuse containers as defined in claim 2 in which said spaced pivot means attached to said lid consists of blocks disposed at each end of said U-shaped flange and containing holes for said bar means.
Claim 5
Dependent Claim
48 words
A hinge structure for refuse containers as defined in claim 3 in which said means disposed between said spaced pivot means consists of a block-like means near the center of said bar means within said U-shaped flange, said flange holding said block from rotating relative to said lid.
Claim 6
Dependent Claim
40 words
A hinge structure for refuse containers as defined in claim 4 in which said torque bar means consists of longitudinal sections and is square in cross section and said fingers are attached integrally to the ends of said bar sections.
Claim 7
Dependent Claim
41 words
A hinge structure for refuse containers as defined in claim 1 in which said torque bar means consists of two longitudinal sections and is square in cross section and said fingers are attached integrally to the ends of said bar sections.
Claim 8
Dependent Claim
126 words
A hinge structure for refuse containers having a body with a top opening and a lid for the opening: said hinge structure comprising a fixture disposed at each end of the upper rear corners of the body and being pivotally connected to the lid, a torque bar attached to said lid in spaced relation to one of said fixtures, a radially extending means adjacent said one fixture, an abutment engageable by said radially extending means on the body for limiting the rotational movement of the end of said torque bar near said one fixture only as said lid is moved toward closed position to cause said bar to assist only the initial opening of said lid and to resist only the final closing of said lid.
Claim 9
Dependent Claim
126 words
A hinge structure for refuse containers having a body with a top opening and a lid for the opening: said hinge structure comprising a fixture disposed at each end of the upper rear corners of the body and being pivotally connected to the lid, a torque bar attached to said lid in spaced relation to one of said fixtures, a radially extending means adjacent said one fixture, an abutment engageable by said radially extending means on the body for limiting the rotational movement of the end of said torque bar near said one fixture only as said lid is moved toward closed position to cause said bar to assist only the initial opening of said lid and to resist only the final closing of said lid.
Claim 10
Dependent Claim
30 words
A hinge structure for refuse containers as defined in claim 7 in which a flange is attached to the rear edge of said lid and substantially encloses said torque bar.
Claim 11
Dependent Claim
55 words
A hinge structure for refuse containers as defined in claim 7 in which said means is a finger rigidly attached to the end of said bar adjacent one of said fixtures, and said abutment is so disposed relative to said finger that said finger moves away from said abutment when the lid is partially opened.
Claim 12
Dependent Claim
30 words
A hinge structure for refuse containers as defined in claim 9 in which a flange is attached to the rear edge of said lid and substantially encloses said torque bar.
