Patent number: 9740170Abstract: An oscillator (10) includes a spiral spring (11) made from a paramagnetic or diamagnetic material and an assembled balance wheel (12) having a shaft (13) on which the following elements are fitted: a balance wheel (14), a plate (15) and a collet (16) rigidly connected with the spiral spring (11). The maximum diameter (Dmax) of the shaft is less than 3.5, or even 2.5, or even 2 times the minimum diameter (D1) of the shaft on which one of the elements is fitted, or the maximum diameter (Dmax) of the shaft is less than 1.6, or even 1.3 times the maximum diameter (D2) of the shaft on which one of the elements is fitted.Type: GrantFiled: October 23, 2012Date of Patent: August 22, 2017Assignee: ROLEX SAInventors: Jean-Louis Bertrand, Benoit Boulenguiez, Thomas Cimprich, Raoul Behrend

Patent number: 8672535Abstract: This spiral-spring and balance wheel regulating member includes a shaft mounted pivotably on the frame of a timepiece. The spiral spring includes at least one blade, whose inner end is designed to be fixed to the pivot shaft and whose outer end is made in one piece with a member (2) for connection to the frame, the rigidity of this connecting member being substantially greater than that of the spiral. The connecting member (2), on one hand, and the frame (9) or a member (6) for the angular positioning of the regulating member on the frame, on the other hand, both have respective bearing surfaces which are at least partially complementary, and these complementary bearing surfaces are joined.Type: GrantFiled: September 29, 2011Date of Patent: March 18, 2014Assignee: Rolex S.A.Inventors: Benoit Boulenguiez, Eric Jolidon

Patent number: 7927008Abstract: This escapement comprises a balance wheel fastened to an impulse element (7a), an escape wheel (1), a detent swing-arm (2) having a stop element (2a) and a disengagement element (2b), a disengagement finger (11d), constrained to rotate with the balance wheel, to come into engagement with the disengagement element (2b) of the detent swing-arm (2) once per oscillation period of the balance wheel. The disengagement finger (11d) is fastened to an inertial member (11) mounted to move freely between two extreme positions in one of which the trajectory of the disengagement finger (11d) passes through the disengagement element (2b) of the swing-arm (2) and in the other of which this trajectory does not pass through this disengagement element (11b), the passage of the inertial member (11) from one position to the other resulting from the inertia force caused by the variations of speed of the balance wheel in each alternation of oscillation of the balance wheel.Type: GrantFiled: December 10, 2009Date of Patent: April 19, 2011Assignee: Rolex S.A.Inventors: Fabiano Colpo, Benoit Boulenguiez
