Title: GUIDANCE DEVICE WITH FLEXIBLE HIGH FATIGUE RESISTANCE PSEUDO-PARALLELOGRAMS
Abstract:
The device, which is capable of translationally guiding a component, comprises: - two pairs (30, 30') of flexible beams (31, 32, 31', 32') that are symmetrical relative to an axis (20), the two beams of a pair being curved and not parallel to each other; - a central mechanical structure (3) intersected by said axis (20), on which structure said pairs of beams are fixed at fixing points (B, C, A', D'), said mechanical structure being capable of being mechanically linked to said component; - two mechanical interfaces (4, 4') each having a pair of beams fixed thereto at fixing points (A, B, C', D'), said interfaces being capable of being fixed on a mechanical structure; the two sets of fixing points (A, B, C, D, A', B', C', D') located either side of said axis of symmetry each forming a parallelogram, the guidance of said component being obtained by a force exerted on said central mechanical structure parallel to said axis of symmetry.
