Abstract

An improved motorcycle steering lock assembly smoothly and reliably operates to immobilize the rotating shaft upon which the handle bars and front wheel forks are installed. The lock, mounted in front of the motorcycle seat and in close proximity to the handle bars and rotating shaft, selectively engages a receiving detent in the rotating shaft so as to prevent rotation of the steering assembly when the motorcycle is not in use. In particular, the steering lock assembly of the present invention comprises: a housing having a shell portion at one side and a base portion at the opposite side; a lock plug assembly rotably disposed in the shell portion of the housing and having a spindle which rotates when the lock plug is turned by a key; a locking bolt slidably disposed in a projecting sleeve in the base portion; a movable bolt means for selectively positioning the bolt between an engaged position wherein the bolt extends beyond the sleeve of the base portion of the housing (so that the bolt can engage the receiving detent of the rotating shaft) and a disengaged position wherein the bolt is fully retracted within the sleeve (so that the bolt cannot engage the receiving detent); and a drum operated camming means coupled to the lock plug spindle and rotably mounted in the housing for linearly actuating the movable bolt means.
