Abstract
Abstract An improved bicycle lock, featuring a U-shaped shackle, a cross bar and means for securing one to the other, is disclosed. The means for securing the shackle to the cross bar also functions as a fulcrum, permitting a tilting movement between the two parts, required in assembling and dissassembling them. The means further includes a locking mechanism removably mounted in the cross bar in between the shackle's legs, and features a dead bolt. The cross bar extends beyond the shackle's legs less than twice the diameter of one of those legs, resulting in a compact and sturdy design. A plastic cover encloses at least the cross bar and is preferably formed of two parts slidably fitted over the cross bar, with means for securing the two parts to one another. Preferably, an environmental protection means is provided for the locking mechanism.
