Abstract:
1. A movement mechanism for moving at least an interception element mounted mobile on a support frame, to assume an optimized interception condition, said movement mechanism being able to be mounted on said support frame and to be constrained to said interception element, to allow the movement thereof with respect to the support frame, and comprising a drive member able to generate a determinate motion, and a transmission kinematism able to transmit the motion generated by the drive member to a rotation shaft constrained to the interception element, wherein said transmission kinematism comprises a screw gear with gears mounted rotatable on a first support and mechanically connected to said drive member, and a toothed wheel with gears engaged on said screw gear, mounted rotatable on a second support, and keyed to said rotation shaft, the first support and the second support being pivoted to each other with respect to a determinate pivoting axis, to be able to be relatively rotated around said pivoting axis, so as to reciprocally bring together/distance the screw gear and the toothed wheel wherein said movement mechanism comprises at least a thrust wedge element, disposed in cooperation with a pin constrained to the second support or the first support by an elastic member able to act on said thrust wedge elements, so that the thrust wedge element is kept elastically in cooperation with the first support or the second support, so as to generate an elastic thrust action of the relative first support or second support toward the opposite second support or first support, and to maintain a condition of proximity between them, and wherein the thrust wedge element is disposed with a first inclined surface in cooperation with the pin so as to stop on said pin and impart the desired thrust on the support and with a second surface resting on a contrasting surface, the contrasting surface being a surface of the support opposite the one to which the pin is constrained.
