A training wheel assembly for children's bicycles includes an elongated bracket having a lower portion adapted to adjustably mount a training wheel, and an upper portion formed with multiple, vertically spaced hexagon-shaped apertures each adapted to receive the rear wheel axle of the bicycle. A brace arm is provided to assist in carrying torque applied to the bracket, and includes a hexagon-shaped projection at one end adapted to releasably lock within the hexagon-shaped apertures of the bracket, and a pair of spaced fingers at the other end adapted to mount to a frame member of the bicycle. The angular position of the brace arm relative to the bracket is adjustable so that the spaced fingers of the brace arm may be positioned to mount over and embracingly engage the rear fork member of varying configurations of forks of bicycles. |

DETAILED DESCRIPTION OF THE INVENTION Referring now to the drawings, the rear portion of three bicycles 10, 12, 14 of slightly different design are illustrated in FIGS.
1, 2 and 3, respectively.
Each of the bicycles 10, 12, 14 include a rear axle 16 threaded at each end which is adapted to span a pair of spaced, substantially parallel fork members 18 which form part of the bicycle frame.
Supported between the fork members 18 by the rear axle 16, are the rear wheel 22, its hub 24, a chain drive sprocket 21, chain 23, and a chain guard 30.
Each rear fork member 18 includes a substantially flat plate 32 which is formed with a slot 34 adapted to receive the threaded end of the rear wheel axle 16.
The rear wheel axle 16 is adjustable along the length of the slot 34 to vary the tension of the drive chain in a well known manner.
The design of bicycles 10, 12 and 14 differs in that different frame members are accessible in the area of the rear wheel axle 16.
For example, in the bicycle 12 shown in FIG.
2, the chain guard 30 extends to the rear wheel axle 16 and completely covers one of the rear fork members 18.
The bicycle 12 includes a luggage or article support 36 having a pair of spaced support arms 38, 40 which are attached at opposite ends of the rear wheel axle 16 and are unobstructed by the chain guard 30.
The bicycle 14 shown in FIG.
3 also includes a chain guard 30 which overlies one of the rear fork members 18.
In this bicycle, the posts 42, 44 which support the bicycle seat (not shown) mount to opposite sides of the rear wheel axle 16 and are not covered by the chain guard 30.
The bicycle 10 shown in FIG.
1 is a somewhat different design than either of the bicycles 12 or 14 because the chain guard (not shown) does not cover either of the rear fork members 18 in the area of rear wheel axle 16.
Referring now to FIG.
1, the training wheel assembly 46 of this invention is shown in an exploded view.
As described below, the training wheel assembly 46 is adapted to mount to unobstructed frame elements of each of the bicycles 10, 12 and 14 shown in FIGS
