Problems solved by technology

[0003] However, the mechanical performance of escapements is generally poor, since the best type of escapement (the Swiss lever escapement) is generally considered to transmit only about 30% of the energy it receives to the regulating member

Embodiment Construction

[0023] In the following, an orientation of rotation, in particular a direction of rotation, is provided with reference to the drawings.

[0024] will refer to Figures 1 to 8 A first embodiment of the escapement of the timepiece movement according to the invention is described.

[0025] According to this embodiment, the escapement is intended to be equipped in a timepiece movement comprising a balance with sprung and an escapement mobile connected to a mainspring gate by a time train. Such an escapement is in this embodiment a constant-force escapement and comprises a strike lever that cooperates on the one hand with the escapement mobile and on the other hand with the control of the arbor fixedly connected to the balance with sprung Component collaboration.

[0026] In this first embodiment, the escapement has an escapement mobile 1 comprising an escape wheel 1.2 mounted on an axle 1.1 and passing through a time train (not shown) Kinematically connected to the clockwork sp...

Abstract

A timepiece movement includes an escapement mobile connected to a barrel by a going train and a spring balance as well as an escapement mechanism (1) including an impulse lever (8) and at least one regulating member (9). The impulse lever (8) and the regulating member (9), which co-operate with the escapement mobile, are controlled by control members (6.1, 6.2, 7.1) supported on the axle of the balance. Between positions in which they co-operate with the escapement mobile (1) and positions in which they do not co-operate with the escapement mobile, the impulse lever (8) and the regulating member (9) move in two different planes forming an angle therebetween.

Description

technical field [0001] The invention relates to an escapement for a timepiece movement. Background technique [0002] In a timepiece movement, the purpose of the escapement is to hold and count the oscillations of a regulating member of said movement, such as, for example, a balance with sprung hair. The escapement receives the energy provided by the spring brake of the timepiece's movement and allows the periodic release of some of this energy to return to the regulating member the energy lost by friction. It is important that the escapement interferes with the adjustment member to the least extent possible. [0003] However, the mechanical performance of escapements is generally poor, since the best type of escapement (the Swiss lever escapement) is generally considered to transmit only about 30% of the energy it receives to the regulating member. In particular, this is due to the inertia of rapidly moving parts, friction, impact and the inevitable presence of lost trave...
