Abstract
A bicycle pedal for permitting a user wearing in-line skates to pedal a bicycle. The bicycle pedal includes a crank with a generally cylindrical rod rotatably coupled to one end of the crank. A sleeve with alternating grooves and ridges is disposed around the rod. An in-line skate is rotatably mounted to an end of the rod opposite the end of the rod coupled to the crank.
Claims12
A pedal structure, comprising:
- a crank having a pair of opposite ends and a longitudinal axis extending between said ends of said crank;
- a rod having a pair of opposite ends and a longitudinal axis extending between said ends of said rod;
- a first of said ends of said rod being rotatably coupled to one of said ends of said crank;
- and
- an in-line skate wheel being rotatably and detachably mounted to a second of said ends of said rod.

A pedal structure, comprising:
- a crank having a pair of opposite ends and a longitudinal axis extending between said ends of said crank;
- an elongate generally cylindrical rod having a pair of opposite ends and a longitudinal axis extending between said ends of said rod, said rod having a generally circular transverse cross section taken substantially perpendicular to said longitudinal axis of said rod;
- a first of said ends of said rod being rotatably coupled to one of said ends of said crank to permit free rotation of said rod about said longitudinal axis of said rod;
- said longitudinal axis of said rod being extended substantially perpendicular to said longitudinal axis of said crank;
- said rod having a length defined between said ends of said rod and an outer diameter defined substantially perpendicular to said longitudinal axis of said rod;
- wherein said length of said rod is about ten times said outer diameter of said rod;
- an in-line skate wheel adapted for mounting to an in-line skate, said in-line skate wheel being rotatably and detachably mounted to a second of said ends of said rod to permit free rotation of said in-line skate wheel about an axis coaxial with said longitudinal axis of said rod and to permit detachment of said in-line skate wheel from said second end of said rod;
- a resiliently deformable sleeve being disposed around said rod to substantially cover said rod;
- said sleeve having a pair of opposite ends and a longitudinal axis extending between said ends of said rod, one of said ends of said sleeve being positioned adjacent one of said ends of said rod, the other of said ends of said sleeve being positioned adjacent the other of said ends of said rod;
- said longitudinal axes of said rod and sleeve being generally coaxial with one another;
- said sleeve having a plurality of alternating annular grooves and annular ridges therearound arranged in a row extending between said ends of said sleeve, said row of grooves and ridges terminating at a groove at both ends of said sleeve;
- each of said grooves of said sleeve being adapted for resting a wheels portion of an in-line skate thereon such that said groove is positioned in a gap formed between a pair of adjacent wheels of the in-line skate so that each of the adjacent wheels engages a portion of said sleeve;
- and
- each of said grooves of said sleeve having therearound a striated surface for frictionally enhancing contact between said sleeve and the wheels of an in-line skate in contact with one of said grooves of said sleeve.
