Appeal No. 96-1881
Application No. 08/095,476
APPENDIX
37. A shoe sole including a bladder, said bladder made of
an elastomeric material and comprising upper and lower surfaces
defining at least three pressurized fluid-filled chambers, each
chamber having a different volume from the other said chambers,
said upper and lower surfaces in contact at one location to
define a blocking seal, each said chamber having an end, each
said end disposed adjacent said blocking seal, said blocking seal
precluding fluid communication between any one said chamber and
another said chamber through said ends, wherein said at least
three chambers are pressurized to the same pressure and thereby
have a different resistance to compression.
40. A method of making a shoe sole comprising the steps of:
forming a bladder having opposing surfaces from elastomeric
material, said bladder formed to include two chambers opened at
one end to a common area, said chambers isolated from each other
except at said common area;
supplying fluid into said bladder, said fluid flowing
through said common area so that each chamber is pressurized; and
joining said surfaces to each other at the common area after
the chambers are pressurized and thereby isolating said chambers
out of fluid communication from each other.
