Appeal 2006-3169
Application 09/829,883
Appellant invented a vibration isolation member that provides
substantially equal dynamic stiffness in radial and axial dimensions and
includes an outer member, an inner member, and a resilient member
disposed between and bonded to the inner and outer members (Specification
[0001] and [0022]). The dimensions of the peripheries of the inner and outer
members provide for an interference between the inner and outer members
to afford a fail-safe feature in the event the resilient member fails
(Specification [0001], [0007], and [0021]).
Independent claim 1 is illustrative of the invention and reads as
follows:
1. 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
