Definitions

  • the present invention relates to the field of watchmaking. It relates, more particularly, to a watch provided with a control member of the internal mechanism comprising a so-called winding stem carrying a maneuvering ring and extending in a tube passing through the case of a watch, in which the operating ring has an oblong or rectangular shape and comprises means for allowing a repositioning of the major axis of the ring parallel to the plane of the housing in order to avoid any injury to the wearer of the watch.
  • screwed crowns are commonly used.
  • This type of crown has the particularity of being able to take a unscrewed position in which the watch can be reassembled, put on time etc. and a screwed position in which the ring is screwed and locked on a tube driven or screwed into the middle of the watch case to compress a seal, thus improving the seal of the watch.
  • the screwed position corresponds to the normal position when the watch is worn.
  • crowns bearing on their end face an inscription or a pattern for example a logo, a trademark or a similar sign and comprising means for bringing the crown in a specific orientation with respect to the box after their screwing so that the inscription or the pattern is always in the same orientation.
  • EP 1 411 401 EP 1 124 167 , EP 2 182 417 , EP 1 701 225 and WO2014 / 067743 especially.
  • the document EP 1 411 401 discloses a particular ring comprising, on its upper outer face, a steerable substrate with respect to a head formed by a central body and a side skirt, the substrate being provided with an inscription and being able to be disengaged in rotation from the crown head when pressure is exerted against braking means.
  • This particular solution has the disadvantage of being somewhat robust with respect to shocks, the latter also being able to exert a pressure force on the substrate and thus reorient it inadvertently with respect to the body of the ring. Moreover, this solution is not suitable for a crown of oblong or rectangular shape in particular.
  • the document EP 1 124 167 describes a crown comprising a hollow cap on an outer face of which the logo to be oriented is machined, and within which the orientation device is arranged.
  • a shape memory alloy ring is placed between the caseband and a tube, or between the ring and a tube for adjusting, in a position or orientation determined, a ring after screwing thereof on the tube.
  • This type of crown has several disadvantages. Indeed, this solution increases the size of the ring and is more expensive to achieve insofar as the shape memory alloys are not currently available in the form of small bars.
  • the document EP 2 182 417 discloses an alternative device for the orientation of a screwed crown with a hood provided with a logo, said device comprising three tubes, two of which are mutually oriented relative to each other by means of teeth which are maintained in contact via a nut.
  • the document EP 1 701 225 describes an adjustable crown screwed with a conventional hood on which there is an inscription, and a head integral with a winding stem.
  • the head and the cap are secured in rotation by means of frustoconical surfaces kept in contact with one another by means of an elastic element, and the adjustment of the angular position of the cap is effected by axially withdrawing the latter from the middle part along the longitudinal axis of the crown.
  • a rotatable screw element comprising a cover and a device for adjusting the angular orientation of the cover relative to a middle watch.
  • the device for adjusting the angular orientation of said cover comprises a first part provided with a first planar friction surface, a second part integral with the cover provided with a second planar friction surface and return means tending to make integral. in rotation said hood and said first part.
  • the cover and the first part are axially movable relative to each other between a first position in which the first planar friction surface and the second planar friction surface are pressed against each other by said means in such a way that the cover is rotationally fixed with respect to the first part, and a second position in which the first planar friction surface and the second planar friction surface are no longer in contact, the cover being then free to rotate around the axis of rotation of the rotatable screw element.
  • the present invention thus aims to overcome the drawbacks of the aforementioned prior art by providing a device for the orientation of a crown of oblong or rectangular shape, simple and economic, the size can be reduced, with or without a pattern such as a logo or a mark, and in which the position of the crown can easily be adjusted in a position or orientation determined in which the major axis of the crown extends parallel to the plane of the housing.
  • the invention relates to a control member of the internal mechanism of a watch, said member comprising at least one said winding stem carrying a maneuvering ring and extending in a tube passing through the case of the watch, remarkable in that the operating ring has an oblong or rectangular shape and comprises at least one recess formed on the proximal face of said ring, said recess being adapted to receive a ball of a ball pawl integral with the case of the watch so to allow a repositioning of the crown so that the major axis of the crown extends parallel to the plane of the middle-bezel of the watch.
  • This arrangement makes it possible to simply and economically provide the orientation of a crown of oblong or rectangular shape, with or without a pattern such as a logo or a mark, while limiting the size of the crown.
  • the ring preferably comprises at least two recesses made on its proximal face, said recesses extending on either side of the winding stem and being able to receive the balls of two ball pawls integral with the housing of the watch, said ball pawls extending on either side of the tube.
  • Each recess is hemispherical and preferably has a radius substantially equal to the radius of the ball of each ball pawl.
  • said ring has an oblong truncated cone shape whose large base forms the proximal face of the crown.
  • the tube advantageously comprises near its threaded distal end, an annular groove receiving an O-ring to ensure sealing between the ring and the housing.
  • the invention also relates to a timepiece comprising a control member as previously defined.
  • the timepiece can be a watch provided with an oblong shaped control member, with its return mechanism inside.
  • control member of the internal mechanism of a timepiece such as a watch
  • said control member according to the invention can be adapted to any type of timepiece without departing from the scope of the invention.
  • the timepiece consists of a wristwatch 1 comprising a watch case 2 which comprises in particular a caseband 3, a lens 4 and a bottom 5 removably mounted on the caseband 3, a casing ring 6 ensuring the positioning of a movement 7 in the watch case 2, said movement 7 comprising at least one hour hand 8, a minute hand 9 and a second hand 10 and carrying a dial 11 covering the plate of said movement 7 .
  • Said middle-telescope 3 consists of two parts 3a and 3b, a first so-called central part 3a having an upper opening 12 intended to be closed by ice, a lower opening 13 intended to be closed by the bottom 5, as will be detailed further, and a second generally U-shaped peripheral portion 3b extending around the periphery of the central portion 3a to which it is attached.
  • the central portion 3a has a substantially rectangular shape and the peripheral portion 3b has an open rectangle shape.
  • the peripheral portion 3b is fixed to the central portion 3a by means of screws 14 cooperating with threaded holes formed in lugs 15 projecting outwardly from the side and / or longitudinal walls of the central portion 3a.
  • central portion 3a and the peripheral portion 3b may have any shape such as a circular or ovoid shape for example without departing from the scope of the invention.
  • the movement 7 is arranged in the central portion 3a so that the dial 11 bears on a shoulder 16, said movement 7 being fixed inside the central portion 3a by means of the casing ring 6 which is secured to the central portion 3a by screws 17, and that the floor 18 of the movement 7 is eccentric with respect to the center of the central portion 3a while extending in the center of the central portion 3a / peripheral portion 3b together to provide an appearance asymmetrical visual.
  • the central portion 3a comprises at least one slot 19 formed in one of the inner walls of the central portion 3a to allow passage of the end of the body of the seconds hand 9 said second hand.
  • Said slot 19 extends parallel to the dial between the window and the shoulder on which the dial 11 bears.
  • one of the longitudinal walls of the central portion 3a has a hole 20 for the passage of the tube 21 winding 22 which will be detailed a little further.
  • Said longitudinal wall comprising the hole 20 for the passage of the tube 21 of the winding 22 is convex and said slot 19 for the passage of the end of the body of the second hand 10 is formed in the inner face of the longitudinal wall opposite to that comprising the hole 20 for the passage of the tube 21 of the winding 22.
  • central portion could comprise a second slot to allow the passage of the end of the body of the minute hand 9 for example, depending on the selected eccentricity, without departing from the scope of the invention.
