Patent ID: 8563858

Claim:
A system comprising: a plate having a longitudinal axis; at least one guide having a longitudinal axis, the at least one guide being coupled to the plate; and a slide slidably coupled to the at least one guide and arranged to travel in a direction of movement, wherein the longitudinal axis of the plate, the longitudinal axis of the at least one guide, and the direction of movement are all parallel, the slide including: a first arm having a total length that extends along the direction of movement of the slide, the first arm constrained by the at least one guide to travel in the direction of movement, wherein the first arm has a thickness extending in a direction away from the plate, the direction being perpendicular to the longitudinal axis of the plate; and a lever arm having a total length that extends perpendicular to the direction of movement of the slide, the lever arm being coupled to the first arm, wherein the lever arm has a thickness extending in a direction away from the plate, the direction being perpendicular to the longitudinal axis of the plate; wherein the total length of the first arm is greater than the total length of the lever arm.
