Abstract:
A hinge (100) including a first hinge leaf assembly, a second hinge leaf assembly pivotally coupled to the first hinge leaf assembly (101), a spring (138) operatively connected to the first and second hinge leaf assemblies, and a spring tensioning mechanism to adjust the bias of the spring (138). The first hinge leaf assembly includes a first hinge component (101) having a first mounting surface for securing to a first structure and a plurality of first knuckles (114, 115). The second hinge leaf assembly includes a second hinge component having a second mounting surface for securing to a second structure and a second knuckle (123). The spring biases the first hinge leaf assembly and the second hinge leaf assembly toward a closed position, wherein the spring is located with a hollow defined by coaxial alignment of the plurality of first knuckles (114, 115) and the second knuckle (123).
