  • Patent number: 4556322
    Abstract: An arrangement for measuring dimensions and/or checking the dimensional accuracy of large objects (1), such as car bodies or the like. The arrangement comprises a straight movement path (8) and one or a plurality of transmission units (10) movable along the path. During indication of each checking point which may comprise a bolt head, a suspended measuring rod (2-7) or the like, two measuring light beams are projected onto the point concerned from two different directions. When the light beams are projected, two are predetermined and one a variable of the following components: the distance between the starting positions for the first and the second light beam, the angular position between the first light beam and a line drawn between the starting positions and the angular position between the second light beam and said line.

  • Patent number: 4441818
    Abstract: A deflection unit on a path parallel to a light beam has a rider, which grips the track of a measuring guide (not shown) and permits a beam component to pass while deflecting a component. A levelling means is provided on a line bisecting the angle between the incoming and the deflected beams in or parallel to their common plane to facilitate remote positional measurements of reference points on a body in order to make measurements more accurate.
