Abstract
A pedal assembly mountable on a bicycle crank arm associated with a bicycle drive assembly; the pedal assembly comprising: a pedal which is operably connected to a retaining member; the retaining member including a first end and a second end and on one side a spigot which engages the crank arm to enable support of the pedal assembly by the crank arm; the pedal including a first connection which engages the first end of the retaining member and a—second connection which engages the second end of the retaining member, wherein the first and second connections allow the pedal to move relative to the retaining arm during rotation of the crank arm.
Claims33
A pedal assembly mountable on a bicycle crank arm associated with a bicycle drive assembly;
- the pedal assembly comprising:
- a pedal which is operably connected to a retaining member;
- the retaining member including a first end and a second end and on one side a spigot which engages the crank arm to enable support of the pedal assembly by the crank arm;
- the pedal including a first connection which engages the first end of the retaining member and a second connection which engages the second end of the retaining member;
- wherein the first and second connections allow the pedal to move relative to the retaining arm during rotation of the crank arm.
A pedal assembly according to claim 2 wherein, movement of the pedal relative to the retaining member allows the pedal to advance and retract during rotation of the crank arm.
A pedal assembly connectable to a bicycle crank arm;
- the pedal assembly comprising a pedal body which includes a tread which receives a rider's foot;
- a retaining member which receives and retains the pedal body and is connected via a spigot to said crank arm, the retaining member having a first and second end, the first end including a coupling which retains a part of the pedal body to the retaining member, the second end including a coupling which retains another part of the pedal body;
- the first end coupling comprising an offset spigot which allows the pedal to move relative to the retaining member;
- the second end coupling comprising a link arm which engages the pedal and the retaining member and allows the pedal to move relative to the retaining member;
- wherein as the crank arm rotates during riding of the bicycle, the pedal moves relative to the retaining member such that at least for part of a revolution of the crank arm the pedal alters its position relative to the retaining member forward and rearward.
A pedal drive assembly for a bicycle;
- the assembly comprising a pair of crank arms each having a first end connected to a drive shaft and a second end connected to a pedal assembly;
- the pedal assembly including a pedal body mounted to a retaining member via swivel connections, the swivel connections allowing each pedal body to at least partially rotate relative to the retaining member;
- wherein as the crank arms rotate an increase in torque is achieved by advancing of the pedal during at least part of the arc of rotation of the crank arms, while maintaining a rotational circumference substantially the same as that defined by a pedal connected directly to the crank arm.
