ABSTRACT:
A bicycle lock comprised of a U-shaped shackle and a bolt lockable across the end of the shackle is detachably connected to a bracket mountable to the bicycle frame for storage purposes. The lock bolt is formed with a flat shank portion and an enlarged end portion. The shank portion passes through a pair of opposing slots formed at the ends of the shackle legs to engage a locking mechanism on one leg of the shackle. The enlarged end of the bolt prevents the bolt from passing through the shackle leg and also serves to engage the bracket. The bracket preferably is formed from two strips of metal bent and joined to define a pair of parallel leg sections with a pair of spaced apart semi-cylindrical portions one of which engages a part of the bicycle frame while the other engages the enlarged end of the bolt. Integral tab portions are formed on the free end of the bracket to extend through the shackle slot and against the shank of the bolt to hold the lock assembly in clamping engagement against the bracket. The lock assembly may be separated from the bracket by either unlocking the bolt from the shackle or bending the legs of the shackle together sufficiently to clear the tabs of the bracket.
