US 2008/0164676 A1 · Bicycle training wheel assembly

Abstract

A training wheel assembly for standard bicycles comprises training wheels connected by resilient legs to a dynamic compression fitting. The wheels project generally rearwardly and outwardly apart from the bicycle rear. Adjustable mounting brackets enable wheel height to be varied. The dynamic compression fitting comprises an adjustable flange section mounted to the bicycle frame within the standard trapezoidal void to the rear of the crank sleeve. A pair of yoke segments can be slidably adjusted to accommodate varying dimensions. An intermediate flexing section resiliently coupled beneath the flange section receives ends of the legs and establishes an up and down pivot. A damper section connected beneath the intermediate section comprises a rigid, tubular sleeve that slidably receives a tubular cap. A resilient grommet coaxially confined between the sleeve and the cap is compressed by an elongated through bolt coaxially penetrating the compression fitting. The bolt establishes a radial pivot.

Dependent claims

A training wheel assembly adapted to be mounted upon a conventional bicycle for stabilizing it, the bicycle comprising a pedal-driven crank, a sleeve for the crank, a rear wheel, a pair of side frame tubes extending from the crank sleeve to the rear wheel, and a generally trapezoidal or void defined between the side frame tubes proximate the crank sleeve, the assembly comprising:

a pair of spaced apart training wheels adapted to be disposed on opposite sides of the bicycle adjacent said rear wheel;
a pair of rearwardly projecting, offset training wheel support legs for mounting the wheels;
and,
a dynamic compression fitting for flexibly mounting the training wheel legs, the compression fitting mounted within said void region, the compression fitting comprising:
an adjustable mounting flange section secured proximate said void region upon said bicycle side frame tubes;
an intermediate flexing section resiliently coupled to and disposed immediately beneath said flange section for receiving the training wheel legs and establishing a first pivot;
a damper section disposed beneath said intermediate flexing section;
and,
an elongated through bolt that generally coaxially penetrates said flange section, said flexing section, and said damper section for axially compressing said sections together, said bolt establishing a second pivot point.
