Positive-lock clamp / adapter
A wheel clamp attaches to a vehicle wheel for performing a wheel alignment on the vehicle. The wheel clamp has a mechanism to mount on the studs of the wheel and to securely mount on the flat surface of the rim. The wheel clamp may have a retractable mechanism that while mounted on the wheel's stud, can slide along the length of the stud without the need to turn it using the threads of the stud. Different methods may be used to attach to the stud, such as by means of treading a device, using a contraction mechanism or magnetic attraction. The wheel clamp has a crossbar and mechanism for supporting a measuring sensor, head or target and can be accommodated to different sizes, shapes and patterns of wheels and studs in the automotive industry.
1. A clamp/adapter pair directly mountable on a vehicle rim for attaching heads, sensors or targets during wheel alignment of a vehicle, each member of the pair comprising:
a cylinder ( 20 ) having a back surface and a front surface ( 21 ), the cylinder ( 20 ) containing a sliding mechanism ( 2 , 3 ) and an interchangeable apparatus ( 1 ) constructed to allow the cylinder ( 20 ) to slide onto a vehicle lug nut's threads ( 5 ) and then grip the threads ( 5 ) when the sliding mechanism ( 2 , 3 ) is released;
an internal mechanical apparatus ( 9 ) mounted in the interchangeable apparatus ( 1 ) constructed to be threaded onto the vehicle lug nut's threads ( 5 ) after the sliding mechanism ( 2 , 3 ) is released; the internal mechanical apparatus ( 9 ) constructed to be tightened with a gadget ( 7 ) attached to an internal shaft ( 8 ) that cooperates with the internal mechanical apparatus ( 9 ) causing the cylinder ( 20 ) to make a positive mechanical connection the vehicle rim ( 6 );
the cylinder ( 20 ) having a protruding central circular end ( 22 ) extending outward from the back surface.
2. The clamp/adapter pair of claim 1 , wherein the cylinders ( 20 ) of the pair are adapted to be mounted separated from one-another on the rim ( 6 ) using two lug nut's threads ( 5 ) that are opposite one-another on the rim ( 6 ); and wherein, a machined crossbar ( 13 ) is adapted to be attached to the protruding central circular ends ( 22 ) of the cylinders ( 20 ) of the pair.
3. The clamp/adapter pair of claim 2 , wherein the machined crossbar ( 13 ) is configured to mount heads, sensors or targets.
4. The clamp/adapter pair of claim 2 , wherein the machined crossbar ( 13 ) includes a plurality of openings ( 16 ) constructed to match different sizes and shapes of rims and bolt patterns.
5. The clamp/adapter pair of claim 2 , wherein the machined crossbar ( 13 ) can be extended away from the cylinders ( 20 ) with extenders ( 19 ).
