Abstract
The device comprises a fixed base (1) and a support (3) for the optical component, together with at least one intermediate plate (2). These parts are hinged to one another by means of at least two independent hinge means each of which comprises a rod (13) co-operating with grooves (9, 10) provided respectively in facing plane faces of two of the parts (2, 3) for guiding said parts in rotation, screw adjustable abutment means (17, 18) for separating the plates (2, 3) from each other, and a resilient clip (14) placed astride the guide means (9, 10, 13) and the adjacent edges (11, 12) of the plates (2, 3) and urging them towards each other.
Claims23
A device for orienting an optical component, said device comprising:
- a first plate forming a fixed base having first and second faces;
- a second plate separable from said first plate and having first and second faces, for receiving the optical component relative to said first plate;
- and
- a first hinge means for rotating said second plate and the optical component relative to the first plate about a first axis of relative rotation and for maintaining the optical component at a selected orientation, said first hinge means including,
- first and second grooves formed in facing portions of the first face of the first plate and the first face of the second plate, respectively, said grooves formed along an edge of each of said first faces along said first axis of relative rotation between said first and second plates,
- a first body of revolution constituting the first axis of relative rotation between said first and second plates, said first body of revolution cooperating with surfaces of said first and second grooves,
- a first resilient return means including a U-shaped clip fitted astride said first body of revolution and bearing against the second face of the first plate and the second face of the second plate, said first resilient return means insuring contact between said first body of revolution and the surfaces of said grooves and urging return rotation between said first and second plates to a closed parallel position, removal of said first resilient return means permitting an easy replacement of said first and second plates;
- and
- a first adjustable abutment means opposing the return action of the first resilient return means of said first hinge means.

A device for orienting an optical component comprising:
- a first plate having first and second faces;
- a second plate having first and second faces hingedly connected to said first plate;
- a third plate having first and second faces and hingedly connected to said second plate;
- a fourth plate hingedly connected to said third plate having first and second faces, for receiving an optical component;
- first hinge means for hingedly connecting first faces of said first and second plates along a first hinge edge of said first and second plates;
- second hinge means for hingedly connecting the second face of said second plate to the first face of said third plate along a second hinge edge of said second plate, said second hinge edge being perpendicular to the first hinge edge;
- third hinge means for connecting the second face of said third plate to the first face of said fourth plate along a third hinge edge of said third plate, which is perpendicular to the first and second hinge edges;
- wherein each of said first, second and third hinge means respectively includes,
- first and second grooves formed in facing portions of the faces of respective hinging plates, said grooves formed along an axis of relative rotation between said hinging plates,
- a body of revolution constituting the axis of relative rotation between said respective hinging plates, said body of revolution cooperating with surfaces of said first and second grooves,
- a resilient return means including a U-shaped clip fitted astride said body of revolution and bearing against nonhinging faces respective to each of said hinge means, said resilient return means insuring contact between said body of revolution and the surfaces of said grooves and urging rotation between said respective hinging plates to a parallel direction, removal of said resilient return means permitting an easy replacement of said respective hinging plates;
- and
- first, second and third adjustable abutment means corresponding to said first, second and third hinge means, respectively, for opposing return action of respective resilient return means.
