  • Publication number: 20050160871
    Abstract: A two position spring biased lever system has a lever that pivots on a support between a first position and a second position, and a torsion spring. The torsion spring has a spring arm that is attached to a central coil at one end and that has an opposite distal end that is engaged in a notch of the lever. The torsion spring is stressed so that the spring arm biases the lever toward the second position while holding the lever in the first position when the distal end is in the notch. The spring arm moves the lever to the second position when the distal end is disengaged from the notch.
