Title: Stabilizer training wheel for bicycle
Inventor: PLANA SALVIO
IPC: B62H7/00
Filed: 1996-07-30
Abstract: This invention is a side wheel attachment (18) for removably attaching an auxiliary side wheel to a bicycle (10). The side whell attachment comprises a single structural rod which is folded in the desired shape, i.e. forms a helical torsion spring (22). In natural unbiased condition, the first and second ends of the spring rod extend generally perpendicularly to one another.      The first end (20) of the spring is inversely U-shaped and tangentially engages by its web the rear axle (14) of the bicycle where it can be fixed after adjusting is vetical position relative to the bicycle. The second end (24) of the spring rod is rotatably engaged by the auxiliary side wheel, therefore acting as its axle. Both ends can angularly move relative to one another due to the helical spring. Therefore, in use, both auxiliary side wheels (installed on one side and the other of the rear bicycle wheel) and the rear bicycle wheel loaded by bicycle rider, always stay in contact with the ground so as to accomplish their rescpective tasks. The novelty of this invention resides in the structural simplicity of the side wheel attachment which is, as previously stated, constructed from a single structural rod.
