Technical Examples

A hinge including a first hinge member and a second hinge member that is rotatably coupled to the first hinge member. The hinge has a torsion spring with a first end of the spring secured relative to the first hinge member and a second end adjustably securable relative to the second hinge member. An adjustment mechanism is included and is capable of disengaging the second end of the spring relative to the second hinge member and into engagement relative to the first hinge member to allow rotation of the second hinge member relative to the second end of the spring, and then re-engage the second end of the spring relative to the second hinge member, thereby changing engagement position of the second end of the spring relative to the second hinge member and adjusting the torsional spring tension.
