Abstract
An in-line skate having tapered, metallic wheels for skating on ice surfaces. The skate has in-line wheels which are made of metal and taper from an inner main body to an outer edge. The tapered wheels contact the ice and provide a low rolling resistance in a forward direction to facilitate high speed skating and provide in the same surface an edge which has a high friction coefficient when the contact with the ice surface is oblique to the forward direction allowing a skate to push off with the wheels oblique to the line of travel and glide along the line of travel.
Claims3
An in-line skate for skating on ice comprising:
- a boot for securing the foot of a user, said boot having a lower periphery;
- a wheel support connected to said lower periphery of said boot and having a central flange, said central flange having a plurality of holes defined therein spaced a predetermined distance apart;
- a plurality of non-plastic wheels each having a central portion, a circumference and a central hole in said central portion defined therethrough and aligned with a one of said plurality of holes in said flange;
- a plurality of bolts bolting said plurality of wheels to said flange and defining an axis of rotation;
- and
- at least one of said plurality of wheels comprises a constant width body section smoothly tapering radially outward from said body section to form a narrow outer edge parallel with said axis of rotation and centered about said wheel for contacting the ice.
