ABSTRACT:
An adjustable elastomer bias device includes a base member (metal or rigid plastic) having plural receptacles for receiving one end of each of a like plurality of bendable, resilient, elastomer rods. An index member is included in the device; the index member has plural rod guide passages and each elastomer rod passes through one guide passage so that the index member can slide longitudinally along the rods, toward and away from the base member. The index member is anchored at one of several displacement distances from the base member to change the effective stiffness (bias) of the rods. The index member may be rotated for torsional bias or moved laterally for linear bias to effect a further bias adjustment; a retainer holds the additional bias adjustment. The bias force of the device results from bending of the elastomer rods.
