Claim 6:
7. A method for resisting motion between two surfaces which may displace relative to one another in a first direction, comprising:
a frame assembly attachable to a first surface;
a slide assembly attachable to a second surface, and slidably connected to the frame assembly;
a brake assembly, which when biased against the slide assembly will resist sliding of the slide assembly, and which when not biased against the slide assembly adds no substantial resistance to sliding of the slide assembly;
a wedge-shaped trigger, comprising a first vertex with a first angle wherein the trigger is spring-urged toward the first vertex at a first force, and bonded to a first brake pad of the brake assembly wherein said first brake pad is in slidable contact with a first surface of the slide assembly;
a power wedge, comprising a second vertex with a second angle wherein the second angle is equal to the first angle of the first vertex of the trigger, and wherein the power wedge is spring-urged toward the second vertex at a second force which is greater than the first force;
a backing plate bonded to a second brake pad of the brake assembly, and in which the second brake pad is in slidable contact with a second surface of the slide assembly;
a first roller, disposed between the trigger and the power wedge;
a second roller disposed between the power wedge and the frame assembly;
a third roller disposed between the backing plate and the frame assembly;
wherein the slide assembly resists sliding when the slide assembly is urged to slide in a first direction, and wherein the slide assembly slides with no substantial resistance when the slide assembly is urged in a second direction opposite to the first direction.
