Abstract
A stand includes a frame, a sliding member, and two torsion springs. The frame has two guide rail subassemblies. The sliding member is slidably attached to the guide rail subassemblies. A first end of each torsion spring is connected to the frame, and a second end of each torsion spring is connected to the sliding member to provide an elastic force to overcome the total weight of the sliding member and a load.
