ADJUSTABLE PEDAL

Abstract

An adjustable motorcycle pedal includes a member attached to the motorcycle and a peg attached to the member. The peg is moveable between a first position in which the peg extends from the member in a first direction and is anchored to the member in a manner suitable for a rider's foot to rest on the peg, and a second position in which the peg extends from the member in a second direction and is moveable to adjust the height of the peg relative to the member when the peg is returned to the first position.

An adjustable motorcycle pedal, comprising: a member attached to the motorcycle: and a peg attached to the member, wherein the peg is moveable between a first position in which the peg extends from the member in a first direction and is anchored to the member in a manner suitable for a rider's foot to rest on the peg, and a second position in which the peg extends from the member in a second direction and is moveable to adjust the height of the peg relative to the member when the peg is returned to the first position.

2. The adjustable motorcycle pedal of claim 1, wherein the peg height is adjustable by rotation of the peg.

3. The adjustable motorcycle pedal of claim 1, wherein the pedal is used to actuate a control function and the member is a lever configured to be moved by the rider's foot to actuate the control function.

DETAILED DESCRIPTION

[0027] The embodiments described below are in relation to a brake pedal. However, it should be appreciated that the principles described may be employed in relation to any motorcycle foot pedal, including, but not necessarily limited to brake pedals, gear change pedals or foot rests.

[0028] Referring to FIGS. 2a and 2b, FIG. 2a shows part of a brake pedal assembly in accordance with an embodiment of the invention, with a lever 20 having a foot-peg 22 mounted in a first, higher position relative to the lever 20. FIG. 2b shows the same part of the brake pedal assembly as FIG. 2a, but with the peg 22 mounted at a second, lower position. As will be described further below, the position of the peg 22 can be changed quickly and without use of tools by means of a gripping and flipping action. As shown in FIGS. 2a and 2b, the peg 22 extends substantially perpendicular to the lever 20 (i.e. out of the page), in what will be referred to as the first or normal position of the peg.

[0029] Also partially visible in FIGS. 2a and 2b are an anti-rotation block 24 and a spring 26.

[0030] FIG. 3 shows a cross-section of the peg 22 of FIGS. 2a and 2b. The peg 22 includes a U-shaped castellated strip 30 (typically formed of a metal such as steel), which is attached to and extends from a cylindrical bolt portion 32. The bolt portion 32 is attached at a position such that one side of the castellated strip 30 is further from the axis of the bolt 32 than the other side. The cylindrical bolt portion 32 passes through a shaped aperture 34 in a part of the lever 20. The shaped aperture 34 allows the bolt 32 to pivot through an angle relative to the lever 20. This is shown in FIG. 4 with the peg 22 folded back at an angle to the lever 20. In the depicted embodiment the angle is about 45. In this folded, or second, position, the peg 22 can be rotated about the axis of the bolt. Rotation of the peg 22 through 180 and then returning the peg to the first or normal position will mean that the top and bottom surfaces of the peg 20 have been reversed so as to change the height of the peg (i.e. to change from the position shown in FIG. 2a to that of FIG. 2b, or vice versa). It will be appreciated that the angle between the peg and the lever when the peg is folded need not be 45 but may be any suitable angle such as any angle between 20 and 70, or preferably between 30 and 60 degrees, more preferably between 40 and 50.

[0031] The spring 26 shown in FIGS. 2a, 2b and 4 urges the peg 22 into the first, normal position. Accordingly, to change the height of the peg 22 relative to the lever 20, a user simply pushes the peg against the action of the spring into the second, folded position, rotates the peg through 180 and releases it so that the spring urges the peg 22 back to the normal position but with its top and bottom surfaces reversed.

[0032] It will be appreciated that the peg 22 is adjustable to two different heights, but that pegs may be provided that have more than two heights. For example a peg may have a triangular shape with three surfaces each at a different spacing from the bolt axis, and such that the peg may be rotated through two different angles to obtain a total of three different peg heights. The same principle may be extended to pegs having four or more different heights.

[0033] FIG. 5 shows more detail of the aperture 34 in the lever 20 and shows the bolt portion 32 of the peg 22 in each of the two positionsfirst or normal position 32a and second or folded position 32b. In the first position of the bolt 32a, it extends along an axis X-X, while in the second position of the bolt 32b it extends along axis Y-Y at an angle (e.g. 45) to axis X-X. The shape of the aperture 34 allows the bolt 32 to pivot around an axis orthogonal to the axes X-X and Y-Y intersecting them at the point where the axes cross. Also shown in FIG. 5 is the profile of a keyway 50, 52 formed as a recess in a surface of the lever 20. The keyway has a first part 50 adjacent to the axis X-X of the bolt in the first position 32a, and a second part 52 adjacent to the axis Y-Y of the bolt in the second position 32b.

[0034] FIG. 6 shows the keyway 50, 52 looking towards the aperture 34 in the lever 20 from the direction of the peg 22, but without the peg being present. The first part 50 of the keyway has a parallel-sided, or rectangular shape, while the second part 52 has a circular shape. The reason for this will be apparent from FIG. 7, which shows the anti-rotation block 24 that is fixed to the peg 22, as shown in FIGS. 2a and 2b. The anti-rotation block 24 has a square (or rectangular) protrusion 56 sized to fit into the first, parallel-sided part of the keyway 50, when the peg 22 is in the first position. In this position the peg 22 cannot be rotated due to the presence of the protrusion 56 in the keyway 50. However, when the peg 22 is moved to the second position, such that the axis of the bolt 32 extends through the aperture 34 adjacent to the second part of the keyway 52, the circular shape of the second part of the keyway 52 no longer prevents the protrusion 56 from being rotated and so the peg 20 can be rotated to allow adjustment of the peg height as described above.

[0035] It will be apparent from the above that the brake pedal described provides numerous advantages over prior art designs. In particular the brake pedal combines the functions of a folding peg design and an adjustable peg height. In addition, the peg height can be quickly and easily adjusted without the use of tools by means of a simple flipping grip action. The use of the keyway and anti-rotation block ensures that the peg can only be adjusted (flipped) when it is in the maximum fold-up position. This also ensures that the lever performs like a solid lever and peg pedal during normal operating conditions and while the spring maintains the peg firmly pressed into its normal position. All of the above advantages may also apply to other types of motorcycle pedal, including gear change pedals and foot rests.
