Abstract
A pedal crank for a bicycle comprising structural fibers incorporated in a matrix of polymeric material which has two seats in which two metal inserts are received. The seats have a mouth which opens onto the outer surface of the pedal crank and have a geometry such as to allow the insertion of the inserts from outside of the pedal crank.
Claims37
A force transmitting bicycle component comprising:
- a body of structural fibers incorporated in a matrix of polymeric material that has at least one seat with spaced apart ends that define a recess having a mouth at a first end, a base at a second end and a wall extending between the first and second ends that includes at least two body attachment zones;
- and
- at least one metal insert that fits within the seat creating at least two insert attachment zones, one of said at least two insert attachment zones is dimensioned to complement one of the body's at least two attachment zones in an interference fit and a remaining one of said at least two insert attachment zones is dimensioned to define a gap between itself and a remaining one of said at least two body attachment zones,
- wherein said at least one metal insert is configured to connect to a bottom bracket of a bicycle and has a widened head portion that abuts and extends beyond an outermost surface of said body.

A bicycle crank comprising:
- an elongated body, formed of structural fibers incorporated in a matrix of polymeric material, having first and second ends and first and second sides;
- at least one seat, defining an opening at one end of the body that extends between the sides and defines a mouth on one of the sides and a base on the other side, having walls that are substantially uniform between the mouth and the base;
- and
- at least one metal insert comprising a first coupling zone that substantially engages one end of the opening and a second coupling zone defining an interspace that is a gap between the insert and the other end of the opening,
- wherein said at least one metal insert has a widened head portion that abuts an outermost surface of said body, and extends axially outward from a plane formed by said outermost surface of said body.

A bicycle component comprising a body made from structural fibers incorporated in a matrix of polymeric material, the body comprising:
- at least one seat having an opening therein, the opening comprising:
- a mouth at a first end of the opening;
- a base at a second end of the opening opposite the first end being of a size not greater than the size of the mouth end;
- and
- walls with cross-sections that do not increase from the mouth to the base;
- and
- at least one metal insert that engages the seat;
- wherein at least a portion of the metal insert extends axially outward from the body.

A force transmitting bicycle component comprising:
- a body of structural fibers incorporated in a matrix of polymeric material that has at least one seat with spaced apart ends that define a recess having a mouth at a first end, a base at a second end and a wall extending between the first and second ends that include at least two attachment portions;
- at least one metal insert that fits within said seat and includes at least two attachment portions and a head portion, one of said at least two attachment portions is dimensioned to complement one of the body's attachment portions in an interference fit and a remaining one of said at least two attachment portions is dimensioned to define a gap between it and a remaining one of said at least two body attachment portions, the head portion configured to abut the body at a location radially outward of the mouth of the recess, and extend axially outward from an outermost surface of the body;
- and,
- an adhesive within said gap between said respective body and insert attachment portions.
