ABSTRACT:
Measuring apparatus for use in vehicle collision repair work. The measuring apparatus comprises first and second telescopic extension members each having a first end for affixation, respectively, at first and second reference points. A cross-member is connectible between the second ends of the extension members. Indicator means are provided on each extension member for indicating displacement between the extension member first and second ends. Alignment means are also provided for aligning the extension member second ends on opposite sides of the vehicle center line and at equal distances from that center line. Third and fourth indicator means are also provided for indicating, respectively, the vertical height of third and fourth reference points above a reference line defined by the extension member second ends. The third and fourth indicator means also indicate, respectively, horizontal displacement of the third and fourth reference points from the vehicle center line. The measuring apparatus may be quickly connected to most collision damaged vehicles despite the presence of obstructions which frequently interfere with conventional measuring apparatus. The collision repairman may then, without moving away from the front of the vehicle, align the measuring system with respect to the damaged vehicle, lock it into position and obtain measurements indicative of the extent of collision damage to the vehicle.
