Description détaillée des modes de réalisation préférésDetailed Description of the Preferred Embodiments

L'invention concerne un ensemble 20 de maintien ou d'appui d'un ressort spiral 21 d'horlogerie, comportant un piton 1 et un porte-piton 2.The invention relates to an assembly 20 for holding or supporting a spiral spring 21 of watchmaking, comprising a stud 1 and a stud holder 2.

Ce porte-piton 2 comporte :

  • un premier logement 3 de réception du piton 1 ;
  • des moyens de fixation 4 du piton 1 comportant au moins une vis 5 ;
  • et des moyens de fixation 6 du porte-piton 2 à un mécanisme d'échappement 30.
This bolt carrier 2 comprises:
  • a first housing 3 for receiving the peak 1;
  • fastening means 4 of the stud 1 comprising at least one screw 5;
  • and means 6 for fixing the bolt carrier 2 to an exhaust mechanism 30.

Le piton 1 comporte au moins une surface d'orientation 7 définissant une direction de maintien ou d'appui d'un tel ressort spiral 21.The stud 1 comprises at least one orientation surface 7 defining a direction of support or support of such a spiral spring 21.

La figure 1 illustre l'art antérieur, avec un piton 1 logé dans un alésage 3 du porte-piton 2, et une vis 5 engagée dans un taraudage 21 du porte-piton 2 et venant en appui sur le piton 1 au niveau d'une face latérale.The figure 1 illustrates the prior art, with a stud 1 housed in a bore 3 of the bolt carrier 2, and a screw 5 engaged in a tapping 21 of the bolt carrier 2 and bearing on the bolt 1 at a side face .

Selon l'invention, cette au moins une vis 5 traverse le piton 1 pour son maintien en position indexée et de blocage.According to the invention, this at least one screw 5 passes through the stud 1 for its holding in the indexed and locking position.

Selon un exemple ne faisant pas partie de l'invention, tel que visible sur les figures 4 à 6, le piton 1 comporte au moins un taraudage 8 coopérant avec cette au moins une vis 5. Ce taraudage 8 constitue la surface d'orientation 7.According to an example not forming part of the invention, as visible on the Figures 4 to 6 , the stud 1 comprises at least one tapping 8 cooperating with this at least one screw 5. This tapping 8 constitutes the orientation surface 7.

Et ce porte-piton 1 comporte:

  • un premier alésage 11 pour le passage de chaque au moins une vis 5 ;
  • une première face d'appui 110 pour l'appui en butée d'une tête de vis 51 que comporte cette au moins une vis 5, cette face d'appui 110 étant disposée à l'entrée du premier alésage 11, du côté opposé au premier logement 3 du piton 1.
And this bolt carrier 1 comprises:
  • a first bore 11 for the passage of each at least one screw 5;
  • a first bearing face 110 for abutment support of a screw head 51 that includes this at least one screw 5, this bearing face 110 being disposed at the inlet of the first bore 11, on the opposite side to the first housing 3 of the piton 1.

La tête de vis 51 vient en appui sur la première face d'appui 110 du porte-piton 2. Dans cet exemple, la vis 5 est utilisée de manière conventionnelle, en faisant travailler ses filets par déformation élastique. Le piton 1 n'est plus poussé contre le porte-piton 2 comme dans l'art antérieur, mais il est tiré vers le porte-piton 2 par la vis 5. L'orientation est donnée par la tête de vis 51, qui détermine l'orientation de la vis 5 et donc du taraudage 8 du piton, qui constitue la surface d'orientation 7 du piton 1 pour le maintien du ressort-spiral 21.The screw head 51 comes to rest on the first bearing face 110 of the stud holder 2. In this example, the screw 5 is used in a conventional manner, by making its threads work by elastic deformation. Piton 1 is no longer pushed against the bolt carrier 2 as in the prior art, but it is pulled towards the bolt carrier 2 by the screw 5. The orientation is given by the screw head 51, which determines the orientation of the screw 5 and thus the tapping 8 of the pin, which constitutes the orientation surface 7 of the pin 1 for the maintenance of the spiral spring 21.

Le porte-piton 2 peut comporter un dégagement afin de pouvoir régler le plat du spiral par le desserrage de la vis. En effet, les horlogers veillent à toujours positionner le spiral de manière à ce qu'il soit le plus plat possible. Si le point d'attache sur le piton est, par exemple, plus bas que le point d'attache sur l'axe de balancier, le spiral aura tendance à prendre une forme de parapluie. Pour corriger ce phénomène, l'horloger desserre la vis du piton et remonte le piton jusqu'au moment où les deux points d'attache se trouvent à la même hauteur, et le spiral est ainsi remis à plat. Mais ce réglage n"est possible que dans le cas où le piton peut se déplacer dans le porte piton. Dans l'exemple de la figure 5, le piton ne peut se déplacer que vers le bas ; dans ce cas, la position nominale du piton devrait être choisie de manière à ce que la vis soit centrée dans l'ouverture afin de permettre une correction dans les deux directions.The bolt carrier 2 may have a clearance in order to adjust the spiral flat by loosening the screw. In fact, watchmakers are always careful to position the hairspring so that it is as flat as possible. If the attachment point on the peak is, for example, lower than the point of attachment on the balance shaft, the spiral will tend to take an umbrella shape. To correct this phenomenon, the watchmaker loosens the bolt and raises the bolt until the two attachment points are at the same height, and the hairspring is thus flat. But this setting is only possible in the case where the bolt can move in the piton door.In the example of the figure 5 the piton can only move downwards; in this case, the nominal position of the stud should be chosen so that the screw is centered in the opening to allow correction in both directions.

Dans le mode de réalisation de l'invention, selon la figure 8, le trou traversant le piton empêche le déplacement. Un réglage n'est pas possible dans une version à trou cylindrique ; dans une variante, un oblong autorise ce réglage en hauteur.In the embodiment of the invention, according to the figure 8 , the hole crossing the piton prevents the displacement. Adjustment is not possible in a cylindrical hole version; in a variant, an oblong allows this height adjustment.

De préférence, dans l'exemple selon les figures 4 à 6, la vis 5 est unique, ainsi que le taraudage 8 du piton 1.Preferably, in the example according to Figures 4 to 6 , the screw 5 is unique, as well as the tapping 8 of the piton 1.

Selon le mode de réalisation, selon l'invention, tel que visible sur les figures 7 à 9, le piton 1 comporte au moins un deuxième logement 12 pour le passage sans contact de cette au moins une vis 5, et ce porte-piton 1 comporte :

  • d'un premier côté 13 du premier logement 3 du piton 1, un taraudage 14 coopérant avec cette au moins une vis 5 ;
  • d'un deuxième côté 15 du premier logement 3 du piton 1, un troisième alésage pour le passage d'une tête de vis 51 que comporte cette au moins une vis 5, cette tête de vis 51 coopérant en appui avec la surface d'orientation 7 du piton 1 constituée par un plat 16.
According to the embodiment, according to the invention, as visible on the Figures 7 to 9 , the stud 1 comprises at least a second housing 12 for the non-contact passage of this at least one screw 5, and this stud holder 1 comprises:
  • a first side 13 of the first housing 3 of the stud 1, a thread 14 cooperating with this at least one screw 5;
  • a second bore 15 for the passage of a screw head 51 that comprises at least one screw 5, this screw head 51 cooperating in abutment with the orientation surface of a second side 15 of the first housing 3 of the stud 1; 7 of the piton 1 constituted by a dish 16.

Dans ce mode, le piton 1 est poussé contre le porte-piton 2 par la vis 5, et l'orientation est donnée par la tête de vis 51.In this mode, the stud 1 is pushed against the stud holder 2 by the screw 5, and the orientation is given by the screw head 51.

Dans une première variante de ce mode, pour permettre un réglage en hauteur du piton 1, cet au moins un deuxième logement 12 est oblong dans une direction perpendiculaire à celle de cette au moins une vis 5, pour le réglage en hauteur dudit piton 1.In a first variant of this mode, to allow a height adjustment of the peak 1, this at least a second housing 12 is oblong in a direction perpendicular to that of the at least one screw 5, for the height adjustment of said pin 1.

Dans une deuxième variante de ce mode, pour permettre un réglage en hauteur du piton 1 comme exposé ci-dessus, cet au moins un deuxième logement 12 est dimensionné plus grand que le diamètre extérieur du filetage de cette au moins une vis 5, notamment sous forme d'un oblong, avec un jeu J de réglage pour le réglage en hauteur du piton 1. La tête de vis 51 est d'un diamètre dimensionné pour rester en appui sur la périphérie du deuxième logement 12 en toute position de réglage du piton 1.In a second variant of this mode, to allow a height adjustment of the pin 1 as explained above, this at least one second housing 12 is dimensioned larger than the outer diameter of the thread of this at least one screw 5, in particular under oblong shape, with a clearance J for adjusting the height of the peak 1. The screw head 51 is of a diameter sized to remain in abutment on the periphery of the second housing 12 in any adjustment position of the peak 1.

De préférence, dans ce mode, la vis 5 est unique, ainsi que le deuxième logement 12 du piton 1.Preferably, in this mode, the screw 5 is unique, as well as the second housing 12 of the piton 1.

L'invention concerne encore un mécanisme d'échappement 30 d'horlogerie comportant au moins un tel ensemble 20.The invention also relates to a horological escapement mechanism comprising at least one such assembly 20.

L'invention concerne encore un mouvement d'horlogerie 40 comportant au moins un tel mécanisme d'échappement 30.The invention also relates to a watch movement 40 comprising at least one such exhaust mechanism 30.

L'invention concerne encore une pièce d'horlogerie 50 comportant au moins un tel mouvement 40. De façon particulière, cette pièce 50 est une montre.The invention also relates to a timepiece 50 comprising at least one such movement 40. In particular, this piece 50 is a watch.

  • le maintien du réglage est assuré, et permet l'intégration dans un mouvement haut de gamme ;
  • dans le mode de réalisation proposé, un réglage en hauteur est possible ;
