Abstract:
1. A hinge comprising: a first hinge member; a second hinge member rotatably coupled to the first hinge member; a torsion spring having a first end secured relative to the first hinge member and a second end adjustably securable relative to the second hinge member; and an adjustment mechanism 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 torsional spring tension, the adjustment mechanism being hand operated and comprising a push button that is secured to the second end of the torsion spring, the push button having push button locking surfaces and the second hinge member having second hinge member locking surfaces, the push button locking surfaces engage the second hinge member locking surfaces for securing the second end of the spring relative to the second hinge member, and the first hinge member having first hinge member locking surfaces that also engage the push button locking surfaces, whereby depression of the push button axially compresses the spring and disengages the push button locking surfaces from the second hinge member locking surfaces and into rotationally locked engagement with the first hinge member locking surfaces to allow rotation of the second hinge member relative to the second end of the spring, and release of the push button re-engages the push button locking surfaces with the second hinge member locking surfaces.
