Abstract

A system and method for improving the engagement reliability of a clipless pedal system is disclosed. Briefly, a magnetic material is positioned near the critical engagement point on the pedal. A ferrous material is added to the front edge of the cleat, such that this edge of the cleat is attracted toward the magnetic material, thereby simplifying the engagement process. In certain embodiments, the magnetic material is placed on a biasing element, such that it has an operative and stowed position. In other embodiments, the magnetic material is fixed in location.

Claims

1. A clipless bicycle pedal system comprising:

a. A cleat for attachment to a shoe, having a first tab comprising a magnetic material and a second tab;

b. A bicycle pedal comprising a first retaining element adapted to hold said first tab in place and a second retaining element adapted to hold said second tab in place; and

c. A magnetic material located near said first retaining element.

2. The system of claim 1, wherein said first tab comprises the front tab of said cleat.

3. The system of claim 1, wherein said first retaining element is fixed and said second retaining element is pivotable.

4. The system of claim 1, wherein said first retaining element comprises a space into which said first tab is inserted.

5. The system of claim 4, wherein said magnetic material is located in said space.

6. The system of claim 4, wherein said magnetic material is affixed to a movable element, wherein said movable element is biased so as to position said magnetic material in said space.

7. The system of claim 6, wherein said magnetic material is moved to a stowed position when said first tab is inserted in said space.

8. A clipless bicycle pedal comprising:

a. A bicycle pedal comprising a first retaining element adapted to hold a first tab of a cleat in place and a second retaining element adapted to hold a second tab of a cleat in place, wherein said first tab comprises a magnetic material; and

b. A magnetic material located near said first retaining element.

9. The system of claim 8, wherein said first tab comprises the front tab of said cleat.

10. The system of claim 8, wherein said first retaining element is fixed and said second retaining element is pivotable.

11. The system of claim 8, wherein said first retaining element comprises a space into which said first tab is inserted.

12. The system of claim 11, wherein said magnetic material is located in said space.

13. The system of claim 11, wherein said magnetic material is affixed to a movable element, wherein said movable element is biased so as to position said magnetic material in said space.

14. The system of claim 13, wherein said magnetic material is moved to a stowed position when said first tab is inserted in said space.

15. A method of securing a shoe to a clipless pedal, comprising:

a. Providing a cleat, attached to said shoe, wherein said cleat has a first and second tab, and said first tab comprises a magnetic material;

b. Providing a clipless pedal comprising first and second retaining elements, where said first retaining element is adapted to retain said first tab, and said first retaining element comprises a magnetic material;

c. Moving said shoe toward said first retaining element;

d. Having the magnetic field between said first retaining element and said first tab draw said first tab toward said first retaining element;

e. Engaging said first tab with said first retaining element; and

f. Engaging said second tab with said second retaining element subsequent to said engagement of said first tab.

16. The method of claim 15, whereby said first retaining element is fixed and said second retaining element is pivotable.

17. The method of claim 15, whereby said first tab comprises the front tab of said cleat.

18. The method of claim 15, whereby said first retaining element comprises a space into which said first tab is inserted, further comprising locating said magnetic material in said space.

19. The method of claim 18, wherein said magnetic material is affixed to a movable element, and further comprising biasing said movable element so as to position said magnetic material in said space.

20. The system of claim 19, further comprising moving said magnetic material to a stowed position when said first tab is inserted in said space.
