Abstract (en)
[origin: EP2450756A1] The device (1) has a pivoting mobile (5) including a guide unit arranged for cooperating with a complementary guide unit (9) that includes a roller (3) fixed to a balance (2). The guide unit or complementary guide unit includes a cam arranged to move the mobile closer to a pivot axis (D1) when the balance is pivoting in a pivoting direction and to move the balance from the axis when the balance is pivoting in another pivoting direction opposite to the former pivoting direction. The complementary guide unit or the guide unit includes a fixed finger arranged to cooperate with the cam. The assembly formed of balance and roller is made of silicon, or quartz or silicon or quartz compound or an alloy issued from microelectromechanical system (MEMS) technology or alloy obtained from Deep reactive-ion etching (DRIE) or Lithography, electroplating, and molding process or partially amorphous material. An independent claim is also included for an escape mechanism comprising an anti-trip device.
