Abstract
Abstract A bolt is locked against axial or longitudinal displacement by means of a rotatable locking unit. The locking unit is mounted within an enclosure and, in the preferred embodiment, is keyoperated. The unit includes a pair of locking cams adapted to be rotated into locking engagement with a pair of cooperating holes formed near the end of the bolt. The bolt is fed through a slot in a housing whereupon the cams are turned and locked into position to prevent removal of the bolt. In a preferred form of the invention the housing is fixed to one leg of a U-shaped shackle with the bolt passing through a slot formed in another leg of the shackle to provide a locking mechanism for bicycles and the like. The bolt and shackle are of heavy stock, high strength metal so as to be resistant to bolt cutters and the like.
