Definitions

  • Each compartment contains a spirally wound spring whose first inner end cooperates with the first and second hubs respectively and whose second end cooperates with the drum.
  • the present invention aims to provide an alternative and advantageous construction, to improve the energy performance of a cylinder in a limited space.
  • the invention relates to a barrel and a timepiece and its mounting method as defined in the claims.
  • FIG. 1 a timepiece cylinder 10 illustrating the invention.
  • This barrel 10 comprises a drum 14 which defines two compartments 16a, 16b superimposed with reference to the geometric axis of the barrel and each containing a spring 18a, 18b wound in a spiral.
  • the barrel comprises a first and a second tubular hubs, separated.
  • the first hub 22a is secured to a first cover 24a.
  • the first hub 22a is housed at least partially in the first compartment 16a, said lower with reference to the figure 1
  • the second hub 22b is secured of a second cover 24b, and is housed at least partially in the second compartment 16b, said upper with reference to the figure 1 .
  • Each of the springs 18b, 18a is spirally wound. Their inner end cooperates respectively with a hook which are provided with the first and second hubs and their outer end cooperates with the drum 14.
  • the compartments are open on the side of the lids.
  • cover is meant the element that covers or even closes a compartment of the drum.
  • the first 24a and second 24b covers are free with reference to the drum 14 and are separated from the drum by a gap 30.
  • the covers 24a and 24b are each provided with a peripheral toothing while the drum 14 is free of teeth. One of these teeth is used to arm the springs, while the other is used as PTO, to supply energy to a finishing gear of a timepiece in which is mounted the cylinder according to the invention .
  • the skilled person can choose to use one or other of the lids for winding or for supply energy.
  • covers 24a, 24b are independent of the drum 14, there may be a drum 14 of diameter greater than that of one or both covers 24a, 24b, which increases the number of turns of the springs. 18a, 18b and therefore, the power reserve available.
  • the covers may be supported, each on a shoulder 25a, 25b that respectively comprise the hubs 22a and 22b.
  • the drum 14 comprises a cylindrical wall 26 and a flat wall 28, projecting with reference to the cylindrical wall 26.
  • the flat wall 28 is disposed substantially at mid-height of the cylindrical wall 26 and delimits the compartments 16a, 16b.
  • the cylindrical wall 26 and the flat wall 28 are integrally formed.
  • the plane wall 28 defines, at its center, an opening 28a positioned and dimensioned so as to substantially extend a channel formed by the hubs 22a and 22b. At the opening 28a, the flat wall may have an extra thickness to position the hubs in height. Between the lower hubs 22a and 22b and the walls of the drum 14, compartments 16a and 16b are thus defined.
  • compartments 16a, 16b take place, respectively, the first spiral spring 18a and the second spiral spring 18b.
  • the inner end cooperates with the lower hub 22a or the upper hub 22b, via the hooks mentioned above.
  • the outer end of the springs 18a, 18b cooperates with the cylindrical wall 26 of the drum 14.
  • the skilled person may consider making a fixed or sliding cooperation, of a type known in the field of barrels.
  • the two springs 18a, 18b are mounted so that the spirals they describe are in opposite directions.
  • the two springs of the barrel 10 being interconnected via the cylindrical wall 26 of the drum 14, they are thus arranged in series.
  • At least one of the covers is provided on its face facing the compartments with an anti-friction coating 50.
  • the two covers are thus provided with such antifriction coating 50.
  • the flat wall 28 may be provided on at least one of its faces facing the compartments, preferably on both sides, an anti-friction coating.
  • the friction coating can be achieved by a washer fixed to the cover 24a, 24b or to the flat wall 28.
  • the washer can be glued or deposited on the cover or on the flat wall.
  • a housing can be provided in the covers and / or in the flat wall, to accommodate the coating.
  • the antifriction coating may be made of a material selected from PTFE (polytetrafluoroethylene), or DLC (diamond like carbon), or silicon, or in another hard material within the reach of the skilled person.
  • PTFE polytetrafluoroethylene
  • DLC diamond like carbon
  • silicon silicon
  • the barrel 10 according to the invention does not have a pivot, in the usual sense of the term in terms of timepieces.
  • the barrels of the state of the art comprise an axis on which is mounted the inner end of the spring.
  • the ends of the axis define pivots which pivot in bearings of the frame of the timepiece in which the barrel is mounted.
  • the hubs and the drum pivot on a fixed shaft which takes place in the channel defined by the hubs 22a and 22b and by the central opening 28a of the flat wall.
  • the shaft 20 is arranged in the frame of the timepiece.
  • the barrel as defined by the present invention forms a functional whole constituted by the hubs 22a and 22b, the drum 14 and the springs 18a and 18b. According to this definition, the barrel pivots on the shaft 20 which is associated with it.
  • the shaft 20 serves to guide the barrel in rotation, without defining a pivot relative to the frame of the timepiece.
  • the shaft 20 may advantageously comprise bearing surfaces 20a, 20b for positioning in height, that is to say along the axis of the shaft, the hubs 22a and 22b and the drum 14.
  • the shaft also participates in defining means for axial positioning of the barrel, to maintain the relative positioning of the components of the barrel.
  • the shaft 20 can receive a screw 34 or a nut, clamped against a third bearing 20c of the shaft. It will be noted that the axial positioning means do not force the hubs against each other and leave them free to rotate.
  • the shaft 20 is provided to be assembled on the timepiece independently of the constituents of the barrel.
  • the shaft participates in both the axial positioning means and the rotating guide means.
  • the shaft can thus receive a bearing screw 34 or a nut holding the hubs and the drum axially.
  • the shaft is intended to be free and independent from the plate and defines only the axial positioning means.
  • the means for guiding the drum in rotation is a bearing 52 acting at the periphery of the drum.
  • the bearing serves as an interface between the drum and the frame of the timepiece and allows to suspend the barrel without the use of a bridge. External rollers could also be used to pivot the drum.
  • the lower hub 22a serves as a rotational guide for the upper hub 22b.
  • the lower hub 22a can advantageously participate in the axial positioning means, receiving, at its end, a nut or a bearing screw 34.
  • the lower hub forms a tube that can be positioned on a fixed shaft integral with the timepiece.
  • the barrel can thus form an independent, functional assembly, without pivot or axis of rotation, which can be assembled independently of the timepiece and then be mounted on the axis, previously fixed to the timepiece.
  • the springs can be connected to their respective hub by rotating each of the hubs until its hook cooperates with the inner end of the spring.
  • the proposed constructions are advantageously simple in that they comprise a small number of parts and a small footprint. Both springs can be mounted independently of each other, which also facilitates assembly operations.
  • This return can, for example, be the average wheel of the movement.
  • springs used either springs of the automatic winding type, that is to say allowing a limitation of the arming, or springs of the manual winding type, cooperating rigidly with the drum 14.
