Abstract
The invention concerns a device for fixing and adjusting a member to be supported, characterised by the fact that it comprises: a support base (1); two triangular levers (6), each of the said levers comprising two arms (7, 8) disposed in a triangle and connected together at one of the vertices (9) of the triangle, each of the said levers being articulated on the said base at its respective vertex, a first one (7) of the two arms of each lever being extendable and connected at its free end to means of fixing (14) to the said member; and an adjustment means (5) mounted on the said base and arranged to make the second arm (8) of each lever pivot in the plane of the said lever. Application to the fixing and adjustment of a precision optical element.
Claims19
A device for fixing and adjusting a member to be supported, comprising:
- a support base;
- two triangular levers, each of the said levers comprising two arms disposed in a triangle and connected together at one of the vertices of the triangle, each of the said levers being articulated on said support base at its respective vertex, a first one of the two arms of each lever being extendable and connected at its free end to means of fixing support to said member;
- and
- adjustment means mounted on said support base and arranged to make the second arm of each lever pivot in the plane of said lever.
A supporting device comprising:
- a support;
- a plurality of levers;
- each of said levers having at least a first arm and a second arm substantially disposed in a triangle and connected together at a selected vertex of the triangle;
- each of said levers being articulated on said support at its respective vertex,
- said first arm being selectively extendable;
- and
- an adjuster extending from said support base and operable to allow said second arm of each of said levers to rotate along a selected plane.
An apparatus comprising:
- an optical member;
- a base;
- at least three devices, wherein each device comprises:
- (a) a plurality of levers;
- each of said levers having at least a first member and a second member substantially oriented in a triangular manner and connected together substantially at a selected vertex of the triangle;
- each of said levers being articulated on said base substantially at its respective vertex,
- said first member being selectively extendable and operably connected to the optical member;
- and
- (b) an adjustment assembly mounted on said base and arranged to make said second member of each of said levers move along a selected plane;
- and
- (c) a fixing assembly operably interconnected to said device;
- wherein said fixing assembly of each of said three devices is arranged so as to be fixed to the optical member at at least three distinct points.
