Folding arm for the projection head of an overhead projector

摘要

For simplifying the operation, a pinion gear (10) is arranged on the folding arm (1), which pinion gear is guided on the projection head (7) which is pivotably arranged, a drive element (14) being provided outside the axis of rotation of the folding arm (1) on the overhead projector (2) for the pinion gear (10) in such a manner that the pinion gear (10) is operated when the folding arm (1) is pivoted and, when the folding arm (1) has reached a final position, the projection head (7) is rotated about 180@ and is aligned parallel to the work surface (4) of the overhead projector (2). <IMAGE>
