<p>The subject of the present invention is a mounting and guiding device for a collimator, especially for the collimators intended to be placed in the roof of an aircraft. More precisely, the invention enables a collimator to follow, between a given operational position and a given stowed position, a complex predefined trajectory with a movement, in three-dimensional (X, Y, Z) space, which may have up to six degrees of freedom. The device according to the invention includes a first structure (3) fixed to the aircraft, and including three guide grooves, a first, central, groove (30) along a plane trajectory in a first plane (XY), and two side grooves (31, 32) on either side of the central groove, and following a second and third trajactory located in two planes perpendicular to the first plane. A second structure (4) rigidly attached to the collimator (1) can move along the grooves by means of rolling rollers (8a, 8b, 9a, 9b, 10), the number and shape of which enable this second structure to have the six degrees of freedom along the complex trajectory. One field of application of the invention relates to civil aeronautics. <IMAGE></p> |
