Problems solved by technology

Therefore, the optimization of the two contours is limited by
Furthermore, a coaxial escapement with triple coaxial wheels requires, due to its configuration, a limitation on the volume of the balance and thus on the inertia of the balance
However, limiting the inertia of the balance wheel does not allow for the best isochronous qualities of a timepiece movement, nor does it completely eliminate variations / deviations in the movement's operation

Embodiment Construction

[0033] In the following description, reference is made to a timepiece movement provided with an escapement, preferably coaxial, for an oscillator of the balance-spring type. The usual components of a timepiece movement, well known to those skilled in the art, are described only in simplified form or not at all. Indeed, a person skilled in the art will be able to adjust / adapt these various components and make them cooperate to achieve the function of the timepiece movement. In particular, everything related to an oscillator of the balance spring type will not be described below, although such a balance spring can advantageously cooperate with the coaxial escapement according to the invention.

[0034] figure 1 , Figure 4a , Figure 4b and Figure 5 A part of a timepiece 1 is shown, which includes a timepiece movement 2 . Timepiece 1 is typically a watch or clock.

[0035] Timepiece movement 2 comprises an oscillator with balance and balance spring (not shown), an energy ...

Abstract

The invention relates to an escapement mechanism for a timepiece, comprising: a first escapement wheel, a second escapement wheel, referred to as an impact pinion, and a drive pinion, wherein the impact pinion, the driving pinion and the first escape wheel are mounted on the same axis; an intermediate gear engaged with the drive pinion; a balance plate carrying a plate pin and a direct impact pallet shoe, the direct impact pallet shoe being arranged to cooperate with the first escape wheel; a pallet comprising a pallet head cooperating with the peg, an impact pallet tile arranged to cooperate with the impact pinion, and first and second support pallet tiles arranged to cooperate with the first escapement wheel; the first escape wheel, the drive pinion, and the impact pinion are mounted in this order. The invention also relates to a timepiece movement comprising an escapement and a hairspring and to a timepiece comprising a timepiece movement.

Description

technical field [0001] The invention relates to escapements for timepieces. [0002] The invention also relates to a timepiece movement comprising such an escapement. [0003] Finally, the invention relates to a timepiece comprising such a timepiece movement. The timepiece is, for example, a watch or a clock. Background technique [0004] In the field of horological movements, systems for realizing the escapement function are known. The escapement is usually located between the energy source of the timepiece movement and the balance-spring type oscillator. The purpose of the escapement is to count and keep the balance spring oscillating. Generally, it is known to use a Swiss-pallet-type escapement in certain mechanical watches. This escapement with a Swiss pallet consists of an escape wheel (also called a pallet wheel), a pallet with in and out risers (in and out), and a double plate. The escapement of the Swiss pallet type transmits force from the pallet wheel to the ...
