The projector fixture comprises a union arrangement (2) provided with a connecting component (23) for connection of the fixture to a support structure and at least two arms (1) supported by the union arrangement for pivoting around parallel axes and for radial displacement relative to the axes, so that a first end of the arms can be directed towards threaded apertures (42) in a projector housing wall (41). Each arm has a connecting device (3) for connection of the first arm end with the threaded aperture adjacent to the projector housing wall. The union arrangement releasably maintains the other end parts of the arms. The connecting device (3) incorporates a screw (31) which with clearance extends through an aperture through the arm first end part and two threaded nuts (33,34) which are fitted on each side of the arm. |
