Abstract

An asymmetrical resistant hinge set includes at least a resistant hinge and an elastic element coaxially positioned. The resistant hinge is hinged on a first pivotal means located on the bottom side of a body. The elastic element provides action forces on the resistant hinge and one-way resistance to generate an asymmetrical hinge effect with a greater resistance in one direction and a smaller resistance in another direction when a support lid is flipped in forward and reverse directions to reduce the resistance of the resistant hinge. As a result, when the support lid is flipped to a selected angle it still can bear the weight of the body of a portable electronic device at the anchored position without drifting.

Claims

1. An asymmetrical resistant hinge set comprising at least one resistant hinge and an elastic element positioned coaxially;

the resistant hinge being hinged on a first pivotal means located on a bottom side of a body, the elastic element providing an action force on the resistant hinge and an one-way resistant force so that a greater resistance is generated in one direction and a smaller resistance is generated in another direction when a support lid is flipped forwards and backwards to form an asymmetrical hinge effect to reduce resistance of the resistant hinge.

2. The asymmetrical resistant hinge set of claim 1, wherein the resistant hinge includes an anchor seat, an anchor slider, a moving slider, a spring, a pintle, a pintle sleeve and a nut, the pintle having a stem to hold the spring, moving slider, anchor slider and anchor seat in this order and being fastened by the nut.

3. The asymmetrical resistant hinge set of claim 1, wherein the elastic element is a torsional spring.

4. The asymmetrical resistant hinge set of claim 1, wherein the elastic element is a torsional reed.

5. The asymmetrical resistant hinge set of claim 1, wherein the elastic element includes at least one elastic member.

6. The asymmetrical resistant hinge set of claim 2, wherein the pintle sleeve includes a coupling portion at one end to hold the elastic element and a latch slot adjacent to the coupling portion wedged in by a first leg of the elastic element and an insertion trough at another side to hold a fastening end of the pintle.
