3. 197 now U.S. No. 3.746.367. invention relates auxiliary bicycle for stabilizing alignment of bicycle. and particularly to auxiliary wheels.

the inventive wheels are as training since this the most use of wheels. However. term is used to any auxiliary bicycle wheels of whether are used training a to ride bicycle. stabilizing a motorcycle. or like. Bicycle generally requires and balance. comes from experience. In to acquire experience. it common practice attach a of small. wheels at back of bicycle to stability despite inexperienced riders of balance.

attachment and of such is a consuming chore: the user reluctant to the wheels after the rider has his training. if someone wishes to the bicycle. has the of riding the training in place of not at all. addition. the needs and change; therefore. is desirable provide optional of training during a of time the beginner acquired some of basic but before is a experienced rider.

For example. beginner may able to two-wheeled over clean. dry. pavement. However. same beginner not ride over the surface covered a thin of loose . for Thus. it be desirable the beginner be able ride without wheels until comes to loose sand.

he should able to lower the wheels. and ride on he again to clean. pavement where training wheels raised and riding is The training in common are very unsuitable since tend to in planes are not parallel to planes of main bicycle Thus. the wheel tends drag slightly which often the wheel brackets. As brackets bend. dragging force the tendency bend the still further.

the training are a hinderance than Finally. these wheels should relatively low They are for only short period time. and beginner is to spend much for Thus. there the conflicting of sturdy. aligned. retractable which do cost very

Accordingly. there a need new and training wheels. greater detail. object is provide training which are to attach remove. sturdy to withstand abuse. and sell for low cost. addition. an is to wheels which so simple retract that a small can manipulate In particular. objective is provide a mechanism which not fail if a operates them an inept

The outer of the 36 is. to a 39 which through the 28; therefore. can swing the position in FIG. in the A. The 37 includes aperture or suitable support for receiving axle for supporting a wheel 46. axle 45 a hub for capturing retaining the 46 in area defined. the inner by a or a 48.

The end of axel 45 captured and held in on bracket 37 by nut 49. the wheel is free rotate in unencumbered manner. foregoing use the terms and outer” for convenience expression only. should be that these terms depend the viewpoint by the In this case. these are used member 36 hinged at 39 which inside the formed by brackets 26.

Therefore. no significance should attached to particular use these terms. are provided latching the into either extended or retracted position. greater detail. first latch a bifurcated 56 rigidly to the 36. A member 57 pivotally attached the bifurcations means of pin 58. that the member may in the B. when lever 59 pushed in C. A spring inside post 56 forces the member 57 the capture seen in drawing.

A latch member (FIG. 3) a spring or captureing 6i (FIG. and a ball or member 62. cap 61 affixed to outer vertical member 26. the detent 62 is to the horizontal member When the 35 swings the extremity its motion direction A. ball 62 captured in spring clip (FIGS).

The used to the training exclusively to rear axle the bicycle vary. depending the bicycle structure- In detail. the 26 includes hold 65 is sized fitover the 18 of bicycle. The position of hole fixes elevation of trainingwheels relative the ground. it may desirable to a series holes for giving a adjustment.

FIG. shows a attaching bracket shaped to over the axle and and over training wheel member 26 on the axle. Thus, hole 65 fitted over axle 18 I) and the hole in bracket is also over the axle.
