ABSTRACT:
A projector holder has a connecting element with a coupling element for connecting the holder to a supporting structure, and three arms carried by the connecting element for rotation about parallel axes and for radial displacement relative to the axes. One end of the arms is aligned with threaded openings in a projector housing wall, and each arm carries a coupling device for connecting one arm end to a threaded opening in the housing wall. The connecting element releasably secures second end portions of the connected arms. The coupling device has a screw that extends through an opening in the arm, and two nuts mounted on a respective side of the arm. The nuts can be moved to position the arm at a chosen distance from the housing wall and to be tightened against the arm so as to secure the screw against rotation.
