Appeal No. 96-2653
Application No. 08/395,681
APPENDIX
1. A vibration isolator grommet capable of preassembly
with a workpiece and cooperative with a workpiece supporting
structure to limit compression of an elastomeric element of the
grommet, said grommet comprising:
a compression limiting metal sleeve having a cylindrical
portion with a radially outwardly extending flange at
one end thereof, and
an annular elastomeric element having a radially outwardly
extending flange portion at one end thereof underlying the
flange on said sleeve and a cylindrical portion with an
inside diameter complementary to the outside diameter of the
cylindrical portion of said sleeve so as to be acceptable
thereover in a slidable frictional fit, the cylindrical
portion of said elastomeric element having an outside
diameter less than the diameter of a grommet accepting
aperture in said workpiece whereby said grommet is readily
accepted therein, said element having a radially inwardly
extending portion at the opposite end of the cylindrical
portion thereof from the flange portion thereon initially
underlying the cylindrical portion of said sleeve but
movable radially outwardly upon axial advancement of said
sleeve relative to said elastomeric element to lock said
grommet in the aperture in said workpiece, the length of the
cylindrical portion of said metal sleeve being related to
the length of the cylindrical portion of said elastomeric
element so as to be engageable with the supporting structure
