Hinge with multiple torsion springs
First Claim
1. A hinge comprising:
- a first bracket having a base;
a support extending from the base and having a pivot hole defined through the support; and
two holders mounted on the base and each holder having a pivot hole defined through the holder and aligning with the pivot hole in the support;
a pivot pin rotatably mounted through the pivot holes in the support and the holders on the base of the first bracket;
a second bracket mounted to the pivot pin; and
two torsion spring assemblies mounted on the pivot pin, corresponding respectively to the holders on the first bracket and each torsion spring assembly having a disk mounted securely to the pivot pin and having a mounting hole defined through the disk and through which the pivot pin extends and a spring hook formed on the disk; and
a torsion spring mounted around the pivot pin between the disk and a corresponding holder on the first bracket, having two ends and one end mounted to the corresponding holder and the other end hooked detachably onto the spring hook on the disk;
wherein the spring hooks on the disks of the torsion spring assemblies are formed in opposite directions perpendicular to the pivot pin.

Abstract
A hinge has a first bracket, a pivot pin, a second bracket and two torsion spring assemblies. The first bracket has a support and two holders. The pivot pin is mounted rotatably through the support and the holders on the base of the first bracket. The second bracket is mounted to the pivot pin. The torsion spring assemblies are mounted on the pivot pin, correspond respectively to the holders on the first bracket and each torsion spring assembly has a disk and a torsion spring: The disk is mounted securely to the pivot pin and has a spring hook. The torsion spring is mounted around the pivot pin and has two ends. One end is mounted securely on the corresponding holder and the other end is engaged detachably with the spring hook on the disk. The torsion springs provide a recovering force to keep the pivot pin from pivot inadvertently.
