Abstract:
An improved adjustable training wheel apparatus for a bicycle comprising:a right hinged parallelogram structure; means for attaching said right hinged parallelogram structure adjacent to a rear bicycle tire on the right side of a bicycle body; a right limiting means with a first end attached adjacent to the lower and inner part of said right parallelogram structure, and a second end of said right limiting means attached adjacent to the upper and outer part of said right parallelogram structure, whereby said right limiting means limits said bicycle body from leaning to the right; a right restoring means, having a first end of said right restoring means attached adjacent to said first end of said right limiting means, and a second end of said right restoring means attached adjacent to said second end of said right limiting means, whereby said right restoring means restores said bicycle body to an upright position when said bicycle body leans to the right; a right auxiliary wheel rotatably attached adjacent to the lower and outer part of said right parallelogram structure, whereby said right auxiliary wheel leans in concert with said bicycle body, while a fixed distance is maintained at the points of ground contact between said right auxiliary wheel and said rear bicycle tire;a left hinged parallelogram structure; means for attaching said left hinged parallelogram structure adjacent to said rear bicycle tire on the left side of said bicycle body; a left limiting means with a first end attached adjacent to the lower and inner part of said left parallelogram structure, and a second end of said left limiting means attached adjacent to the upper and outer part of said left parallelogram structure, whereby said left limiting means limits said bicycle body from leaning to the left; a left restoring means, having a first end of said left restoring means attached adjacent to said first end of said left limiting means, and a second end of said left restoring means attached adjacent to said second end of said left limiting means, whereby said left restoring means restores said bicycle body to an upright position when said bicycle body leans to the left; a left auxiliary wheel rotatably attached adjacent to the lower and outer part of said left parallelogram structure, whereby said left auxiliary wheel leans in concert with said bicycle body, while a fixed distance is maintained at the points of ground contact between said left auxiliary wheel and said rear bicycle tire.
