Universal frame gauge for motorcycle and bicycle

摘要

The frame gauge (10) is formed from a cross-beam (l1) of prismatic configuration which consists of a middle section (eve) with base parts (11b) arranged at its ends and lower part. A through-going drill hole (12) with decreasing diameter is arranged in the middle section. The drill hole serves for securing the end of a preferably circular profile or a shaft (32), which is led through the interior of the reed (30) of the frame (28). Corresponding side beams (14) and angle measuring devices (19) are provided at the ends of the cross-beam. The vertical position between the side beams and the cross-beam is assured by device of bracing disks (17) which are connected with the side beams and the cross-beam through screws or other mounting devices, and which enable a perfect alignment of side beams and cross-beam in an angle of 90 deg.
