Abstract

A cylindrical peg adapted for side mounting on each axle of a bicycle to extend laterally outward therefrom for riding a rail when participating in the stunt of grinding. The peg includes a rotatable cover to effect a rolling mode on the rail and optionally may include a detent to convert the cover from a rolling mode to a fixed mode by securing the cover against rotation.

Claims

1. A peg for operating a bicycle in the stunt of grinding, wherein the peg comprises:

an elongated cylindrical unit adapted to be received and laterally supported on a wheel axle of the bicycle with which the peg is to be used, wherein the unit includes a central hub defining a concentrically threaded aperture in which to receive the wheel axle of the bicycle and the cover is bearing mounted for rotation about the hub;

a cover defining the periphery of the unit, the cover being supported for rotation so as to effect a rolling mode when engaging an elongated rail in the course of performing the stunt; and

apparatus for converting the peg on site interchangeably between supporting the cover for rotation in the rolling mode and supporting the cover secured against rotation in a fixed mode.

2. A peg in accordance with claim 1 wherein the apparatus comprises a displaceable detent threadedly supported in the hub and the detent is manually displaceable from a first position wherein an end of the detent interlocks the cover against rotation and a second position displaced from the cover so as to permit rotation of the cover.

3. A peg in accordance with claim 2 wherein the hub includes an eccentrically located bore extending longitudinally within the hub and the detent is threadedly contained within the bore for displacement between the first and second positions. inward of the aperture.

4. A peg in accordance with claim 3 wherein the cover includes an aperture opposite the location of the bore and the second position is effected by causing the detent to extend inward of the aperture.

5. A peg for operating a bicycle in the stunt of grinding, wherein the peg comprises:

an elongated cylindrical unit adapted to be received and laterally supported on a wheel axle of the bicycle with which the peg is to be used, wherein the unit includes a central hub defining a concentrically threaded aperture in which to receive the wheel axle of the bicycle and the cover is bearing mounted for rotation about the hub;

a cover defining the periphery of the unit, the cover being supported for rotation so as to effect a rolling mode when engaging an elongated rail in the course of performing the stunt and including an annular recess in the periphery of the cover for engaging a rail in the course of performing the stunt; and

apparatus for converting the peg on site interchangeably between supporting the cover for rotation in the rolling mode and supporting the cover secured against rotation in a fixed mode.

6. A peg in accordance with claim 5, wherein at least a portion of the remainder of the cover periphery beyond the recess includes a knurled finish.
