Patent ID: 7347000

Claim:
Probe including: a fixed organ ( 1 ); a feeler ( 12 ) held by an elastic element ( 21 ) in a resting position relatively to said fixed organ, said resting position being reproducible, said feeler ( 12 ) being capable of moving from said resting position in response to a deflective force and capable of returning to said resting position when said force ceases to be applied; a plurality of mobile positioning elements ( 131 , 132 , 133 , 134 , 135 , 136 , 231 , 232 , 233 ) united with said feeler ( 12 ); a plurality of fixed positioning elements ( 141 , 142 , 143 , 144 , 145 , 146 ) united with said fixed organ and capable of engaging with said mobile positioning elements to define six contact points; characterized in that said six contact points are distributed around the axis of said feeler ( 12 ) so as to obtain an essentially uniform sensitivity to deflective forces in an orthogonal plane to said feeler ( 12 ), said mobile positioning elements comprising pins, said fixed positioning elements comprising spheres, and wherein said pins are arranged in three pairs, in an arrangement essentially symmetrical by 120° rotations, each pair comprising two said pins, each of which touches one of said spheres.
