DEVICE FOR POSITIONING AN OBJECT IN SPACE

"Device for positioning an object in space" Abstract The subject matter of the invention is a device for positioning an object in space comprising at least 4 plates (T1, T2, T3, T4), each capable of moving in relation to one of the other said plates with which it is contiguous along one of the 3 axes of space, the movement of a plate in relation to another plate potentially being guided by a mortise/tenon assembly in which said tenon may be rigidly connected with one of said plates and the mortise thereof may be built into the other plate, the orientation in space of each of the mortise/tenon assemblies being different from the other 2 and along one of the 3 axes of space, characterised in that: Said device is free of all return springs; At least one of the mortise/tenon assemblies may be in a dovetailed shape; A pre-tension aimed at limiting the movement of a plate with respect to another is laterally applied to one of the edges of the tenon of the mortise/tenon assembly, said pre-tension limiting but not preventing the movement of said plates with respect to one another; The movement of at least one plate with respect to another plate may be assured by means of at least one micrometric screw that can act on at least one of the 2 plates that must be moved with respect to one another, said micrometric screw potentially being rigidly connected with one of said 2 plates, said micrometric screw potentially being fastened in direct contact with said plate; The immobilisation of one plate with respect to another plate in the desired position may be assured, independently for each of the mortise/tenon assemblies, by at least one means of immobilisation. «Dispositif de positionnement d'un objet dans l'espace» Abrégé L'invention a pour objet un dispositif de positionnement d'un objet dans l'espace comprenant au moins 4 plateaux (T1, T2, T3, T4), chacun apte à se déplacerpar rapport à un autre desdits plateaux qui lui est contigu selon l'un des 3 axes de l'espace, le déplacement d'un plateau par rapport à un autre plateau pouvant être guidé par un ensemble tenon/mortaise dans lequel ledit tenon peut être solidaire de l'undes plateaux et sa mortaise pouvant être confectionnée dans l'autre plateau, l'orientation dans l'espace de chacun des ensembles tenon/mortaise étant différente des 2 autres et selon l'un des 3 axes de l'espace, caractérisé en ce que: Ledit dispositif est exempt de tout ressort de rattrapage; Au moins l'un des ensembles tenon/mortaise peut être sou
