Abstract: A hinged cord locking device is adapted to be clamped onto the support bar of an article to be locked such as one of the frame bars of a bicycle. The cord may be withdrawn from a spring retractable reel, wrapped around a stationary object and the locking bolt on free end of the cord locked in a locking channel in the hinged body portion of the device to thereby affix the article to the object. The hinged body portions rotatably support the two piece cable reel which is positively interlocked with the body portions to prevent removal thereof from the support bar. The locking channel is defined by the two body portions such that insertion of the locking bolt into the channel locks the cord to the body portions, the hinged body portions together and the cable reel to the body portions. When so locked, the locking device cannot be removed by opening or sliding axially off a support bar.

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.
