  • Patent number: 6938734
    Abstract: A configurable wheel lock comprising a rigid chock and an adjustable fork pivoted to the chock that engages a wheel seated within a cradle. The fork projecting from the control portion mounts a pair of separate arms pivoted to opposite ends of an axle that is slidably captivated within guide slots in the chock sides. Projecting arm stubs are inserted within the wheel to be captivated for locking. The fork arms rotate in a first plane that is coplanar with both arms and the axle, and they may be rotated about the axle. These combined rotational features enhance the positional abilities of the arms, and the dexterity of the wheel lock. Rigid locking-links pivoted to at least one of the arms are extended to the opposite arm to lock it in a selected locking position about the wheel.
