摘要：A generally flat, flexible, resilient, double faced spring used in combination with a generally flat spacer with the spring having the same number of uniform protrusions on each of its flat surfaces, the protrusions on each surface being equidistant from each other. The protrusions have spherical tips which function as multiple fulcrums, a spherical tip protrusion on one side of the spring surface being precisely halfway between the spherical protrusion on the other surface such that no protrusion on one surface is exactly opposite a protrusion on the other. The essentially flat spacer is equipped with protrusion receiving recesses spaced to coincide with the locations of the protrusion on the adjacent spring. The tip of each protrusion of a spring is in alignment with a respective spacer recess so that when multiprotrusion springs are combined with a spacer, they are prevented by the recesses from laterally shifing or moving into a rotational position.
