U-Lock with novel cross-sectional shape
A U-lock, e.g. often used as a bike lock, including a U-shaped shackle that includes two legs extending from a bow, the legs being received in a locked orientation in apertures formed in a crossbar, and a lock mechanism coupled to the crossbar for locking the legs with the crossbar. At least a portion of the U-shaped shackle 12 has a cross-sectional shape of a polygon which has flat sides and none of the flat sides are parallel to each other. One or both legs and bow may include polygonal profile. The polygon may be a triangle, pentagon, heptagon, nonagon.
