Abstract

An adjustable stirrup type motorcycle gear shifter allows the cyclist to slip his shoe into shifting position, either sidewardly or lengthwise, for safe retention during up and down gear shifting.

Claims

1. For combination with a gear shifting crank member adapted to extend lengthwise alongside a motorcyclist'"'"'s shoe, said crank member extending forwardly, the combination comprising

(a) an L-shaped bracket having a first leg connected to the crank member and a second leg projecting laterally to fit over and terminate above a portion of the shoe upper side proximate the toe region, the first leg merging arcuately and smoothly toward the second leg at a junction which is concave toward the shoe, the crank and legs being one-piece, the underside of the second leg being substantially flat to conform to the normally flat upper side of a shoe top portion,

(b) a peg connected to said member and projecting laterally to fit under and terminate beneath a portion of the shoe sole forwardly of the shoe heel, the lateral length of the second leg being substantially less than the width of the shoe toe portion and the length of the second leg in a forward direction being greater than the space between shoe laces, to prevent snagging, the second leg having rounded edges throughout its projecting extent, said edges defining a U-shaped locus which extends laterally from said junction,

(c) whereby the motorcyclist'"'"'s shoe is readily insertible between said second leg and peg and may then be displaced toward either the second leg or peg to rotate the crank member for effecting gear shifting.

2. The combination of claim 1 wherein said L-shaped bracket and said crank member are integral.

3. The combination of claim 1 wherein said L-shaped member has releasable connection to said crank member.

4. The combination of claim 1 wherein said peg has adjustable connection to said crank member characterized in that the peg may be adjustably shifted toward or away from said second leg.

5. The combination of claim 4 wherein the crank member includes a portion defining a slot elongated in the direction of separation of the peg and second leg, said peg including an extension projecting through the slot.

6. The combination of claim 1 wherein the peg includes an elastomeric outer sleeve.

7. The combination of claim 1 including motorcycle structure having a second peg to support an arch portion of the shoe, said first peg spaced forwardly of the second peg, the crank arm connected to the motorcycle transmission.
