Abstract

A bicycle pedal comprises a pedal axle, a pedal body, a movable member, and an actuator. The pedal axle is configured to be secured to a crank arm having a longitudinal axis extending from a rotational axis to a crank rotational axis of the crank arm. The pedal body is rotatably coupled to the pedal axle about the rotational axis. The pedal body has a reference axis perpendicular to the rotational axis of the pedal axle. The movable member is movable relative to the pedal body from a rest position toward an actuated position. The actuator is configured to move the movable member from the rest position toward the actuated position in response to a first relative angle defined between the reference axis and the longitudinal axis of the crank aim when viewed in an axial direction parallel to the rotational axis of the pedal axle.

First claim

What is claimed is:

1. A bicycle pedal comprising:
a pedal axle defining a rotational axis, the pedal axle being configured to be secured to a crank arm having a longitudinal axis extending from the rotational axis to a crank rotational axis of the crank arm;
a pedal body rotatably coupled to the pedal axle about the rotational axis, the pedal body having a reference axis perpendicular to the rotational axis of the pedal axle;
a movable member movable relative to the pedal body from a rest position toward an actuated position; and
an actuator configured to move the movable member from the rest position toward the actuated position in response to a change in a first relative angle defined between the reference axis and the longitudinal axis of the crank arm when viewed in an axial direction parallel to the rotational axis of the pedal axle.

2. The bicycle pedal according to claim 1 , further comprising
a cleat engagement part coupled to the pedal body, wherein
the movable member includes an additional cleat engagement part spaced apart from the cleat engagement part.

3. The bicycle pedal according to claim 1 , wherein
the actuator includes an actuation part engageable with at least one of the pedal axle and the crank arm in response to a relative rotation between the pedal body and the crank arm about the rotational axis.

4. The bicycle pedal according to claim 3 , wherein
the pedal axle includes a first axle end configured to be engaged with the crank arm, and
the actuation part is engageable with the first axle end in response to the relative rotation between the pedal body and the crank arm about the rotational axis.

5. The bicycle pedal according to claim 3 , wherein
the actuator is movable relative to the pedal axle from a non-actuation position toward an actuation position to move the movable member relative to the pedal axle from the rest position toward the actuated position.

6. The bicycle pedal according to claim 5 , wherein
the actuation part is engageable with the at least one of the pedal axle and the crank arm in response to the relative rotation between the pedal body and the crank arm about the rotational axis to move the actuator from the non-actuation position toward the actuation position.

7. The bicycle pedal according to claim 5 , wherein
the actuator is movable relative to the pedal axle from the non-actuation position toward the actuation position to move away from the crank arm in the axial direction.

8. The bicycle pedal according to claim 5 , wherein
the actuation part is movable relative to the at least one of the pedal axle and the crank arm without engaging with the at least one of the pedal axle and the crank arm in an actuation state where the actuator is at the actuation position.

9. The bicycle pedal according to claim 5 , further comprising
a positioning structure configured to position the actuator at the actuation position.

10. The bicycle pedal according to claim 9 , wherein
the positioning structure includes an actuation-position biasing member to bias the actuator toward the actuation position.

11. The bicycle pedal according to claim 10 , wherein
the positioning structure includes a positioning part configured to restrict a relative movement between the pedal body and the actuator in an actuation state where the actuator is at the actuation position.

12. The bicycle pedal according to claim 5 , further comprising
a release structure configured to move the actuator from the actuation position to the non-actuation position.

13. The bicycle pedal according to claim 12 , wherein
the release structure is movably coupled to the pedal body.

14. The bicycle pedal according to claim 13 , wherein
the release structure is pivotally coupled to the pedal body.

15. The bicycle pedal according to claim 13 , wherein
the release structure includes an engagement portion engageable with a cleat to move the actuator from the actuation position to the non-actuation position.

16. The bicycle pedal according to claim 1 , wherein
the movable member includes a coupling part coupled to the actuator.

17. The bicycle pedal according to claim 16 , wherein
the actuator is movably coupled to the coupling part.

18. The bicycle pedal according to claim 1 , wherein
the movable member and the actuator are rotatable relative to the pedal axle about the rotational axis.

19. The bicycle pedal according to claim 1 , further comprising
a rest-position biasing member to bias the movable member toward the rest position.

20. A bicycle pedal comprising:
a pedal axle defining a rotational axis, the pedal axle being configured to be secured to a crank arm having a longitudinal axis extending from the rotational axis to a crank rotational axis of the crank arm;
a pedal body rotatably coupled to the pedal axle about the rotational axis, the pedal body having a reference axis perpendicular to the rotational axis of the pedal axle;
a movable member movable relative to the pedal body from a rest position toward an actuated position; and
an actuator configured to move the movable member from the rest position toward the actuated position in response to a first relative angle defined between the reference axis and the longitudinal axis of the crank arm when viewed in an axial direction parallel to the rotational axis of the pedal axle, wherein
the actuator includes an actuation part engageable with at least one of the pedal axle and the crank arm in response to a relative rotation between the pedal body and the crank arm about the rotational axis,
the pedal axle includes a first axle end configured to be engaged with the crank arm,
the actuation part is engageable with the first axle end in response to the relative rotation between the pedal body and the crank arm about the rotational axis, and
the actuator is provided between the first axle end and the pedal body in the axial direction.

21. A bicycle pedal comprising:
a pedal axle defining a rotational axis, the pedal axle being configured to be secured to a crank arm having a longitudinal axis extending from the rotational axis to a crank rotational axis of the crank arm;
a pedal body rotatably coupled to the pedal axle about the rotational axis, the pedal body having a reference axis perpendicular to the rotational axis of the pedal axle;
a movable member movable relative to the pedal body from a rest position toward an actuated position; and
an actuator configured to move the movable member from the rest position toward the actuated position in response to a first relative angle defined between the reference axis and the longitudinal axis of the crank arm when viewed in an axial direction parallel to the rotational axis of the pedal axle, wherein
the movable member includes a coupling part coupled to the actuator,
the actuator is movably coupled to the coupling part, and
the actuator is pivotally coupled to the coupling part about a pivot axis non-parallel to the rotational axis of the pedal axle.
