Monitor to check the alignment of two hinge axes, at a motor vehicle, has a lamp at one hinge with an indicator at the other for a light beam to show the alignment

摘要

The monitor (1) to check the alignment of hinge axes (2,2') in at least two hinges (3,4), especially at a motor vehicle, has a lamp (5) fitted to one hinge to give a light beam (11) parallel to its axis. An indicator (6) on a plane (12) is at the other hinge with a curved segment (13). The axes are in alignment when the gap (d2) between the segment and the second hinge axis equals the gap (d1) between the lamp and the first hinge axis.
