Abstract
A hinge with a torsion spring has a base, a pintle, at least one torsion spring, two joint members, and two washer assemblies. The base is attached to a support of an LCD display, and the pintle is mounted through the base. The torsion spring is mounted around the pintle, one end of the torsion spring is attached to the base, and the other end is attached to the joint member. When the angle of the display is adjusted, the joint members rotate relative to the pintle. With the torsion resilience provided by the torsion spring, the support will not be rotated with the joint members, so that the users can adjust the display angle with one hand.
