Abstract
This is a corrugated light reflective ring made from thin flexible material and having a light reflective surface on both sides thereof and adapted to be intertwined between the spokes of a bicycle wheel. This invention also embodies the method of making a corrugated light reflective ring.
Claims3
The method of producing a light reflective strip for bicycle wheels comprising,
- providing an elongated strip of relatively thin light-weight malleable material,
- corrugating said strip of material to produce alternate ridges and valleys of substantial depth therein,
- at least partially flattening the corrugations along only one marginal edge portion of the strip to reduce the depth of said ridges and valleys along said one marginal edge portion thereof and thus increase the length of that edge portion as compared with the other marginal edge of said corrugated stip and produce a curved strip wherein the flattened portions form the larger radius of curvature thereof, and
- applying light reflective material to the surfaces of said strip.
