Patent number: 11409243Abstract: A transmission coupling (100), especially a timepiece transmission coupling, for the mechanical linkage of at least one first part (2A) of a first shaft at least movable in rotation about a first axis (A2) to at least one second part (3A) of a second shaft at least movable in rotation about a second axis (A3), the first and second axes being parallel or substantially parallel, the transmission coupling including the at least one first part (2A), the at least one second part (3A), and at least a first elastic return system (15, 16; 18; 16a?-16d?; 111a, 111b; 221, 222, 223, 224) arranged so as to limit or cancel out the play between the at least one first part (2A) and the at least one second part (3A), and connecting the at least one first part (2A) and the at least one second part (3A).Type: GrantFiled: July 5, 2018Date of Patent: August 9, 2022Assignee: ROLEX SAInventors: Raoul Behrend, Blaise Fracheboud, Ludovic Zbylut

Publication number: 20200278644Abstract: A gearing (E1) for a horological mechanism (100), comprising a first toothed wheel (R1) including first symmetrical teeth (d1) and a second toothed wheel (R2) including second symmetrical teeth (d2), each of the first and second teeth being conformed so that the primitive backlash (J) of the gearing is less than 0.3 .m, or even less than 0.25 .m, or even less than 0.2 .m, or even less than 0.15 .m, or even less than 0.1 .m, or even less than 0.08 .m for the nominal axial center distance (e) of the gearing, where m is the modulus of the wheel of which the tooth forms part.Type: ApplicationFiled: February 27, 2020Publication date: September 3, 2020Applicant: ROLEX SAInventor: Raoul Behrend

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: 8876371Abstract: A watch case includes a middle (2, 24, 34), one opening of which is closed by a bezel (8, 18, 28) and/or a crystal (1, 11, 21), or by a back (40). An element for closing the opening is connected to the middle by a resilient metal member (3, 23, 33) having a recessed cross-section defined by the profile of a non-rectilinear wall having a constant thickness, whose ends (3a, 3b) are connected to the periphery of the closing element (1, 11, 21, 18), respectively. The profile of the non-rectilinear wall defines at least one annular fold having an orientation parallel to the plane of the opening, the fold being formed by a curvature whose arc defines an angle of between >90° and 180°, so as to impart to the closing member (1, 11, 21, 18) a freedom of movement relative to the plane of the opening.Type: GrantFiled: March 8, 2010Date of Patent: November 4, 2014Assignee: Rolex S.A.Inventors: Raoul Behrend, Julien Cattaneo, Olivier Kuffer, Antonio Meleddu
