Adjustable bracket in fixtures with a bottom plate (5) for fastening on a supporting structure and a top plate (4) on which a fixture can be mounted. The top plate (4) can be adjusted in the six degrees of freedom in the room. Three adjustment screws (8) in the top plate (4) are used to adjust this vertically and in two angular directions relative the bottom plate. Two adjustment screws (10) in the bottom plate act from the side against a downwards from the top plate (4) protruding part (12), that extends down into a recess (13) in the bottom plate and has a play relative the walls of the recess. By adjustment of the screws (10) the top plate is displaced laterally and an associated angle. A likewise laterally directed adjustment screw (1 1 ) gives displacement in the third longitudinal axis. To each one of the laterally directed adjustment screws also corresponding counter screws (14) belong. They are used to secure that an adjusted lateral position of the top plate is maintained. Corner bolts (15) are used for locking of the top plate (4). The corner bolts (15) pass through holes 15 in the top plate, which have a greater diameter relative the diameter of the bolts. |
