Patent ID: 7316389

Claim:
A single resilient member iso-elastic vibration isolation member comprising: (a) an inner member for attachment to a suspended body, said inner member comprising a frustoconical seat having an angled surface and an outer periphery diameter D′; (b) an outer member for attachment to a planar support structure, said outer member comprising a planar base defining a base plane and a shroud that extends away from the planar base and said base plane, the shroud extending to overlay the inner member outer periphery diameter D′, said shroud having an angled segment with an inner surface, said angled segment inner surface oriented substantially parallel to said angled surface of said frustoconical seat, said shroud defining an inner periphery diameter D″, said inner periphery diameter D″ less than said outer periphery diameter D′, said inner member not extending through said outer member base plane; and (c) consisting essentially of a single sole resilient member constrained between the shroud angled segment inner surface and the inner member frustoconical seat angled surface, said single resilient member having a cross section, said single resilient member bonded to said shroud angled segment inner surface and said inner member frustoconical seat angled surface, wherein said single resilient member bonded to said shroud angled segment inner surface and said inner member frustoconical seat angled surface provides for iso-elastic displacement of said inner member in a radial direction and in an axial direction from said outer member with said frustoconical seat outer periphery diameter D′ providing an interference with said shroud inner periphery diameter D″ to prevent a seperation of the vibration isolation member in the event of a failure of said single resilient member, wherein said single sole resilient member is the sole resilient member providing for isolation between the suspended body and the support structure with said iso-elastic vibration isolation member providing a substantially equal dynamic stiffness in the radial direction and in the axial direction for an applied load between the suspended body and the support structure.
