  • Patent number: 6769192
    Abstract: An extension ruler intended for symmetry measurements of vehicles, having a built in measuring device for the extension of the ruler and transfer of data or figures to a display. The measuring device includes a tape extending from one end of the ruler to the other end where the tape is wound on a drum spring biased in the winding direction, which drum is provided with teeth and that the passage of these is detected and counted by a light source and a photo diode and that the drum rotation detected in this way is used to provide a measure of the extending of the ruler.

  • Patent number: 6598308
    Abstract: Device for measuring the bottom of vehicles comprising an extendable rule that in one end is provided with a conical mandrel for contact with measuring holes or points and that the ruler in its other end is provided with a magnetic fastening means and a centering means for centering the fastening means relative to holes in the bottom. The centering means is a conical mandrel that against the force of a spring can be pushed into the fastening bracket.

  • Patent number: 5636445
    Abstract: A method for the measuring of symmetry when in particular repairing cars including the use of a measurement bar comprising in each end a laser head that can be swiveled around the length axis of the bar. The laser heads can emit light beams perpendicular to the length axis of the bar. The bar is on a straightening bench (on which the car is mounted) mounted perpendicular to the length axis of the car. When the laser heads are swiveled their beams construct parallel planes on each side of the car from which measures can be taken to the sides of the car in order to establish if symmetry exist or how great the necessary correction has to be.
