U.S. Patent No. 7,665,928, issued on February 23, 2010 to Crank Brothers, Inc. of Laguna Beach, CA, discloses a quick-release camming mechanism for bicycles.

According to the ‘928 patent, quick release camming mechanisms for mounting the wheel and/or the seat of a bicycle to the frame can be difficult to close and open, especially for people with less hand strength.  The patent discloses a two-lever configuration which, according to the patent, is substantially easier to open and close, making it easier to fix a flat tire or to adjust the seat height.

According to the company’s website, Crank Brothers is a small company based in a Laguna Beach studio.  Besides the ‘928 patent, the USPTO database lists three other U.S. patents owned by Crank Brothers, directed to a bicycle wheel, a bicycle pedal and crank apparatus, and to a bicycle tire air pump.
