Definitions

  • the present invention relates to a push-button crown suitable for a timepiece, and in particular for high reliability watches.
  • the first two positions correspond to the positions that can be taken by a conventional crown.
  • the third position (position "-1") is known in 'multi-mode' watches, generally in watches with a first analog display indicating the time and a second display, often digital with liquid crystal, indicating one or more other watch functions such as a second hour or a wake-up time, etc.
  • the desired mode can be activated.
  • These push-button crowns are fixed to the movement rod so that when the axial or radial position of the push-button crown is changed, the rod is moved axially or radially.
  • the push crown in the "0" rest position, the push crown is rigidly connected longitudinally to the rod and can be pulled or pushed.
  • the pulled out position (position "1") the push-button crown is also rigidly linked to the rod in order to transmit angular information to the movement, such as for example setting the time by means of this rod.
  • this construction is generally known for simple push crowns, that is to say the push crowns having only two positions, the first (which corresponds to position "0") where the rod is free and a second position (which corresponds to position "-1") where the rod is engaged with the movement, allowing for example the time setting.
  • a push-button crown is described in the document CH 577 701.
  • the push-button crown is also provided with a spring whose advantage is to compensate for a misalignment between itself and the movement.
  • This pusher ring does not have the third position (position "1") and is of a relatively simple construction.
  • the present invention thus aims to remedy these defects while providing a push-button crown which has the seal suitable for high reliability watches.
  • the spring undergoes, in its stable position, a strong precompression so that, after having been brought from its stable position to its fleeting position, it returns completely to its stable position as soon as it is loose, even if the friction due to the seal between the tube and the crown is high.
  • the invention also relates to a timepiece characterized in that it comprises a push-button crown as defined above.
  • Figure 1 shows an embodiment of the pusher ring according to the invention in its rest position, called position "0".
  • the push-button crown 1 is mounted on a middle part C of a watch, preferably high-end, middle part C in the lateral edge of which is mounted a mounting tube T.
  • the latter has a flange annular R defining a radial shoulder E1 bearing on a complementary shoulder E2 formed at the mouth of a radial passage P pierced in the edge of the middle part C.
  • a seal J preferably in silver is interposed between the shoulders E1 and E2 .
  • the tube T also has, near its free end another radial shoulder E3 whose purpose will appear later.
  • the tube T is used, in the usual way for the passage of a winding rod TR which can here occupy three positions defined by the movement (not shown) of the watch to which the middle part C.
  • the three positions of the stem are a neutral position or "0" (figure 1), a drawn position called “+1” (figure 2) in which it allows the time setting of the watch, and a fugitive pushed position called “-1" (FIG. 3) in which it makes it possible to control one or more other functions of the watch, for example by closing an electrical contact (not shown) provided inside the movement.
  • the rod also has a usual thread at its free end in order to allow a push-button crown to be made integral therewith.
  • the push-button crown 1 comprises a hollow head 2, the bottom of which has a projection 3 provided with a blind hole 4.
  • the latter is internally threaded to allow the crown to be screwed onto the end of the rod TR.
  • the inner wall of the head 2 has a radial shoulder 5.
  • this internal wall has an annular groove 6 with a rounded bottom.
  • the head 2 also has an annular groove 7 which is here of rectangular profile.
  • a return spring 8 of helical shape is disposed axially in the hollow head 2 and surrounds the projection 3.
  • This spring is supported by its inner end on the bottom of the head 2, while its opposite end is supported on a ring stop 9 which surrounds the outer end of the tube T beyond the shoulder E3.
  • This ring 9 has an internal flange 10 defining a radial shoulder 11 intended to come into contact with the shoulder E3 of the tube T under the action of the spring 8, at least in the configuration of the push-button crown 1 shown in the figure 1.
  • the stop ring 9 has a beveled annular face 12 which is intended to come to bear against a circlip 13 placed in the annular groove 6 of the head 2.
  • the ring 9 is in abutment against the circlip 13 in the positions " 0 "and” +1 "of the push-button crown 1.
  • the pusher ring according to the invention also comprises a seal made of two rings 14 and 15 of rectangular section and trapped between, on the one hand, a washer 16 bearing against the circlip 13 and, on the other hand , a washer 17 which is in fact a circlip engaged in the groove 7 of the head 2.
  • the spring 8 is in a state of precompression while being trapped between the bottom of the head 2 and the shoulder 11.
  • it generates an axial force in extension incapable of defeating the forces which maintain the rod TR in its neutral position, forces which are conventionally imposed on this rod by the time-setting mechanism (not shown) of the movement of the watch fitted with the push-button crown according to the invention.
  • the precompression can be equal, for example, to 60% of the total clamping force of the spring 8, when all of its turns are clamped against each other.
  • the push-button crown according to the invention is intended more particularly to ensure an irreproachable return stroke of the rod TR from its fleeting position "-1" towards its neutral position "0", and this despite the friction forces which can be exerted on this rod by the seal which surrounds it.
  • the push-button crown 1 can move on either side of its position "0" over a distance which is preferably the same.
  • its axial stroke is the same around this "0" position.
  • this stroke is, for example, 0.35 mm, the distance separating the face of the head 2 facing the middle, and the lateral face of the latter being respectively 0.50 mm , 0.85 mm and 0.15 mm depending on whether the push-button crown is in its "0", "+1" and "-1" positions.
  • these dimensions essentially depend on the construction of the movement at which the push-button crown is associated and they can therefore vary from one type of movement to another.
  • the driving stroke towards the fugitive position "-1" is limited by the shoulder 5 of the head 2.
  • the shoulder 5 comes into contact with the stop ring 9 , the spring 8 is compressed so as to provide a return force which is very close to its maximum compression force (Fmax in FIG. 4). It is possible, according to a variant not shown in the figures, to omit the shoulder 5, whereby the end of the driving stroke will be defined by the total compression of the spring 8, all of its turns then being pressed one on the other. others.
  • the precompression force F o can be chosen according to the needs. For example, in the case of the use of a push-button crown according to the invention in watches for divers, it is important that the water pressure cannot push the push-button crown. We must then choose this precompression according to the depth that can be reached with the watch. We understand that it is necessary push the push crown relatively hard to reach position "-1" for waterproof watches at a very great depth. In such a case, the precompression F o can be equal to more than 70% of the maximum compression force F max .
