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.

An adjustable elastomer bias device comprising: a rigid, fixed base member having N base receptacles, N being an integer larger than one; N elongated organic elastomer rods each having a predetermined length of at least L and a predetermined cross sectional area, one end of each elastomer rod being firmly mounted in each base receptacle with the rods projecting from the base member in a preselected direction; an index member having at least N rod guide passages therethrough, each rod passage through the index member having a cross-sectional area larger than the cross sectional area of the elastomer rod that passes therethrough so that the index member is movable longitudinally along the elastomer rods; and anchor means for anchoring the index member at any one of a plurality of different displacements, in the preselected direction, from the base member.
