Embodiment Construction

[0025] figure 1 A barrel system 1 according to the invention is shown. The barrel comprises a cylinder 2 , here in the shape of a smooth cylinder, particularly adapted to be surrounded by a chain of a cone mechanism (not shown), driving the cylinder in rotation. However, the invention applies equally to drums 2 comprising peripheral teeth. As is generally known, one side of the drum 2 is closed by a barrel bottom 4 forming a box in which a prime mover spring (not shown) is placed. The barrel system also includes a positioning system 3 on the barrel bottom 4, comprising a movable sheave 5 mounted to rotate freely on the barrel bottom 4 by means of a screw 22, the movable sheave being connected to the pin The sub 6 engages for limiting the number of revolutions possible for the barrel cylinder 2, as will be described in detail below. Furthermore, the barrel system comprises a bridge 7 and a mobile dent 8 , the function of which will be explained in detail below.

Abstract

The invention relates to a barrel system (1) for a timepiece, including: a supporting pin (9); a barrel (2, 4) comprising a drum (2) closed by a barrel bottom (4), the barrel housing a mainspring, an outer end of the mainspring being connected to the drum (2); a barrel pin (11) in the form of an hour wheel located in the barrel (2, 4) and surrounding the supporting pin (9), an inner end of said mainspring being connected to the barrel pin (11). According to the invention, the barrel system (1) also includes a rotation transmission pin (12) arranged such as to transmit a rotation motion of said drum (2) to a clockwork element, the rotation transmission pin (12) being in the form of an hour wheel surrounding the supporting pin (9) and being surrounded by the barrel pin (11), the rotation transmission pin (9) being rotatably secured to the drum (2).

Description

technical field [0001] The invention relates to the field of watches and clocks. In particular, the invention relates to a barrel system for a timepiece. Background technique [0002] A large number of barrel systems for timepieces are known from the prior art, such as those described in documents CH 431 389 , CH 333 241 and EP 1 970 778 . However, all these barrel systems have only one mechanical output capable of providing energy and lack the aesthetics that are so important in today's high-end watches that often form a so-called "rack", accessible through a transparent bottom and / or divided The dial sees the movement. [0003] The object of the present invention is therefore to provide a barrel system that makes it possible to transmit the rotational movement of the barrel to the additional mechanism of the timepiece movement and is more aesthetically pleasing and also easy to install on the timepiece In the movement.
