Appeal No. 96-2476
Application 07/890,785
Therefore, only claims 14 through 17 and 22 through 24
are before us on appeal.
The appellant's invention is directed to an in-line
roller skate having a plurality of operating surfaces on each
wheel. The subject matter before us on appeal is illustrated
by reference to claim 14, which reads as follows:
14. An inline roller skate for skating along a skating
surface, said skate comprising:
wheel means comprising at least one wheel attached to
said skate and constrained for rotation about only a first
axis, said wheel means comprising at least a rolling first
surface rotatable about said first axis, a second surface
disposed to one side of said first surface along said first
axis and a third surface disposed on an opposite side of said
first surface along said first axis; and
a first sliding surface disposed between said first and
second surfaces and a second sliding surface disposed between
said first and third surfaces, said first sliding surface
contacting said skating surface only when said skate is tilted
in a first direction and said second sliding surface
contacting said skating surface only when said skate is tilted
in a second direction, each of said sliding surfaces having a
lower friction coefficient than said rolling first surface.
