Abstract

A bicycle fairing for attachment to the handlebar and front wheel of a bicycle is disclosed. The fairing is constructed of a lower portion having a sheet-over-frame construction and an upper portion having a window therein. The window is comprised of a flexible, resilient pane which is unframed to provide the bicyclist with an unobstructed line of vision. The pane portion of the fairing is secured to the handlebar by a flexible line which prevents the pane from vibrating. The fairing is generally semicircular in cross section and is of such a length that it shields the rider'"'"'s entire body, from his head to his feet, when is in a crouched position on the seat, from wind, rain projectiles and the like. The fairing is positioned on the bicycle so that the center point of the semicircular fairing is concentric with the vertical steering axis of the bicycle and so that the medial edges of the fairing extend along the sides of the handlebar. This positioning of the fairing alleviates the stability problems caused by the buffeting of the fairing by crosswinds and headwinds.

Claims

means for stabilizing said free, elastically deformable pane when said shell is positioned on the bicycle.

8. A fairing as recited in claim 7 wherein said means for stabilizing said pane comprises a flexible line connected with said pane, adjacent upper corners thereof, and with the bicycle.

9. A fairing as recited in claim 8 wherein the ends of said flexible line are connected to opposite side edges of said pane;

said means for stabilizing said pane further comprising a cylinder through which each of the ends of said flexible line are passed before said ends are attached to said opposite side edges, said cylinder being slidable along said flexible line to form an adjustable noose therebelow; and

a cord which is first inserted through said adjustable noose and then tied around said handlebars to form a second noose;

whereby the tension on said pane is adjusted by sliding said cylinder along said flexible line.

10. A fairing for bicycles as recited in claim 1 wherein said outer shell comprises:

a frame having spaced apart lateral members connected together at various points along their length by spaced apart, generally semicircular ribs; and

a fabric sheet stretched over said frame to provide a sheet-over-frame construction which is extremely lightweight and affords good protection to the rider shielded thereby.
