Abstract
A derailleur guard adapted to be mounted on a bicycle frame and shaped to protect a rear derailleur from impacts from a generally sideward direction. The derailleur guard includes a forward portion shaped to engage a chain stay of a bicycle frame, a rearward portion shaped to engage a dropout attached to the chain stay, and a loop portion extending between the forward and rearward portions and shaped to extend sidewardly from the frame about a rear derailleur mounted on the dropout of the frame.
Claims2
A derailleur guard for use with a bicycle frame having a derailleur mounted on a rear dropout thereof and a claim stay adjacent to said dropout, said derailleur guard comprising:
- a forward portion shaped to engage said chain stay, said forward portion including a hook shaped to extend about said chain stay, and having interior and exterior legs for engaging interior and exterior sides of said chain stay, respectively, and an angle, extending from said interior leg, having a stop shaped to engage an underside of said chain stay;
- a rearward portion shaped to engage said dropout, said rearward portion including a screw adapted to be threaded into said dropout and flat flange shaped to receive said screw therethrough, said flange being offset from said forward end such that attachment of said rearward end to said dropout causes said guard to pivot about said exterior let relative to said chain stay, whereby said forward portion is caused to bind against said chain stay;
- and
- a loop portion extending between said forward and rearward portions shaped to extend downwardly and sidewardly from said frame when said guard is mounted thereon and provide non-contacting clearance between said derailleur and said guard such that, when mounted on said frame, said guard touches only said frame.
