Patent number: 9459589Abstract: The invention relates to a double balance spring (21) including, made in a layer of silicon-based material (11), a first balance spring (23) coaxially mounted on a collet (13, 27), the collet (13, 27) including an extending part (9) that projects from said balance spring and which is made in a second layer of silicon-based material (5). According to the invention, said extending part extends (17) into a third layer (7) of silicon-based material coaxially with a second balance spring (25) so as to form a one-piece double balance spring (21) made of silicon-based materials. The invention also relates to a timepiece including a balance spring of this type and the method of manufacturing the same. The invention concerns the field of timepiece movements.Type: GrantFiled: March 20, 2009Date of Patent: October 4, 2016Assignee: Nivarox-FAR S.A.Inventors: Pierre-André Bühler, Marco Verardo, Thierry Conus, Jean-Philippe Thiebaud, Jean-Bernard Peters, Pierre Cusin

Patent number: 8622611Abstract: The invention relates to a one-piece hairspring (21, 21?) including, a balance spring (25, 25?) coaxially mounted on a collet (27, 27?), made in the same layer of silicon-based material. According to the invention, the hairspring includes an elevation device (2, 2?) for the outer coil of the balance spring above the layer of silicon-based material so as to improve the concentric development of the hairspring. The invention also relates to a timepiece including a hairspring of this type and the method of manufacturing the same. The invention concerns the field of timepiece movements.Type: GrantFiled: August 31, 2012Date of Patent: January 7, 2014Assignee: Montres Breguet S.A.Inventors: Pierre-André Buhler, Marco Verardo, Thierry Conus, Jean-Phillipe Thiebaud, Jean-Bernard Peters, Pierre Cusin

Patent number: 8550699Abstract: The invention relates to a composite balance (45, 45?) formed in a layer of silicon-based material (21) and including a hub (39, 39?) connected to a felloe (37, 37?) by at least one arm (40, 41, 42, 43). According to the invention, the felloe (37, 37?) includes at least one additional part approximately in the shape of a notched ring (23, 23?) of higher the than the silicon-based material, which increases the inertia of the balance. The invention also relates to a method 1 of manufacturing this type of balance. The invention concerns the field of timepiece movements.Type: GrantFiled: March 13, 2009Date of Patent: October 8, 2013Assignee: Nivarox-FAR S.A.Inventors: Pierre-André Bühler, Marco Verardo, Thierry Conus, Jean-Philippe Thiebaud, Jean-Bernard Peters, Pierre Cusin

Patent number: 7337542Abstract: The method consists, from a profile having a section corresponding either to the envelope of the base of the symbol or to that of its section, in first of all machining the feet, transferring the preformed profile in a clamp, gripping the symbol by the feet, cutting the preform, shaping and diamondpolishing all of the visible faces of said symbol, and transferring said finished symbol into an individual packing tray using a robot.Type: GrantFiled: January 21, 2005Date of Patent: March 4, 2008Assignee: Nivarox-Far S.A.Inventors: Jean-Luc Brazin, Pierre-Andre Buhler

Patent number: 7213966Abstract: The collet is formed by a metal band (10) whose inner contour (11) delimits the recesses (11a, 11b, 11c) for driving the collet onto a balance staff (2) and whose outer contour (12) includes a function point (4) between the collet and the balance spring (9) located at the end of an arm (14) at a distance R from the centre 0 of the staff (2) greater than that of any other point (6, 8, 13, 15, 17) of the outer contour (12). It is characterised in that the inner contour (11) includes a discrete number of points of contact (1, 3, 5, 7) with the staff (2) distributed along identical or different angular apertures ? and in that width “I” of the band (10) varies such that the compression forces of the contact points (1, 3, 5, 7) on the staff (2) do not substantially alter the distance R after driving in, leading to a friction torque allowing angular orientation of the collet on the staff (2) and not introducing any unbalance.Type: GrantFiled: March 31, 2005Date of Patent: May 8, 2007Assignee: Nivarox-Far SA.Inventors: Roger Lambert, Raymond Gabus, Pierre-André Bühler, Marco Verardo, Jean-Luc Bazin
