Definitions

  • the present invention relates to a watch of the wristwatch type, comprising a display, for example an analog time display, a electronic circuit for controlling said display, a time-setting rod and at least two electrical contact elements, each of them opening and alternately closing an electrical connection of said electronic circuit during the rotation of the time-setting rod so as to generate at least two electrical signals formed by pulses, transmitted to said circuit control electronics.
  • a display for example an analog time display
  • a electronic circuit for controlling said display a time-setting rod and at least two electrical contact elements, each of them opening and alternately closing an electrical connection of said electronic circuit during the rotation of the time-setting rod so as to generate at least two electrical signals formed by pulses, transmitted to said circuit control electronics.
  • These watches have a time-setting rod having a square section over part of its length.
  • two cams which can in particular have a substantially square profile, rectangular, triangular or ellipsoidal. These two cams are offset angularly with respect to each other and are mounted on the rod such so that the rotation of the time setting rod causes the rotation of cams.
  • These cams are also arranged near two blades elastic conductors which open and close alternately electrical connections when moved by rotation cams. This has the consequence that during a rotation of the cams, electrical signals formed by pulses are generated, these signals passing through from the open state to the closed state and vice versa, offset in the time.
  • the time-setting rod can usually be placed in positions different longitudinal ones, so as to access different functions of the watch.
  • the cams are sliding on the square section of the time-setting rod so that they always remain opposite the blades regardless of the longitudinal position of the release rod time.
  • This embodiment has various drawbacks.
  • the square section of the time setting rod must be large enough to receive the cams.
  • these cams occupy a large volume. This poses space problems, especially in small watches dimensions, such as ladies' watches or very flat watches.
  • cams must remain opposite the conductive blades implies the establishment of a cam retention element in a position given longitudinal, regardless of the longitudinal position of the rod setting the time. This element also complicates assembly.
  • the present invention proposes to overcome these drawbacks by realizing a watch comprising a time-setting rod not carrying cams sliding, but access to functions is the same as for watches with sliding cams.
  • a wristwatch as defined in the preamble and characterized in that the time-setting rod comprises, on at least one part of its length, at least one helical profile cooperating with said electrical contact elements for alternately opening and closing a electrical connection of the electronic circuit during the rotation of said rod time setting.
  • the time-setting rod comprises two helical profiles.
  • the time-setting rod comprises three helical profiles.
  • each profile helical has a constant helix pitch.
  • the electrical contact elements are preferably separated from one given distance d.
  • the helical pitch of the helical profiles, the angular offset of these profiles as well as the distance d separating the electrical contact elements are determined so that the signals electric formed by the alternating opening and closing of each electric contact element during constant speed rotation of the rod time setting have a duty cycle of between 30% and 70%, and advantageously substantially equal to 50%.
  • the pitch of the helical profiles, the angular offset of these profiles as well as the distance d separating the electrical contact elements are advantageously determined so that the electrical signals formed by the alternative opening and closing of each element of electrical contact when rotating the setting rod at constant speed the hour are substantially in quadrature.
  • each electrical contact element cooperates with said zone of the time-setting rod comprising at least one helical profile, for all the longitudinal positions of the time-setting rod, except at maximum one position of this rod.
  • the watch 10 notably comprises a display 11 such as a analog or digital time display, an electronic circuit 12 of control of said display, a time-setting rod 13 and two elements of electrical contacts 14, 14 '.
  • these electrical contact elements are elastic conductive strips.
  • the time setting rod 13 is formed essentially from four zones.
  • a zone 15 includes a time setting crown 16 accessible from the outside of the watch case and allowing the user to move the time-setting rod in rotation and thus access certain functions of the watch.
  • the rod also has two cylindrical zones 17, 18 ensuring guidance of the time-setting rod both in rotation and in translation.
  • the time setting rod has a zone 19 having at minus a helical profile, this area being referred to below as the area helical 19.
  • FIGS. 3A to 3C which are cross-sectional views of the helical zone 19 of different rods of time setting, this area has three helical profiles 20, 20 ', 20 ".
  • FIG. 3A illustrates a first embodiment of the helical zone 19 a time-setting rod.
  • This area is a ruled area, which means that each section perpendicular to the longitudinal axis of the rod is delimited by line segments 21.
  • This embodiment allows a simple manufacturing.
  • FIG. 3B illustrates an embodiment in which the sections of the helical zone 19 of the rod are delimited by arcs of a circle 22.
  • these sections are delimited by a slightly curved curve 23. It is clear that others curve shapes could also be chosen.
  • the shape of these sections is essentially determined by the method chosen for the manufacture of the time-setting rod.
  • FIG. 3D has two profiles helical 24, 24 'for moving the contact elements electric.
  • Figure 4 illustrates the two electrical contact elements 14, 14 '.
  • these elements of contacts are formed by two elastic, electrically conductive blades and separated by a given distance d.
  • These contact elements are preferably made in one piece so that the distance d between the two blades cannot be modified during assembly in the watch. he it is however also possible to make the contacts so independent and to maintain the distance d by mounting.
  • the electrical contact elements 14, 14 ′ are mounted in the watch of such that they alternately open and close circuit connections electrical circuit 12 as a function of the part of the profile helical which moves these contacts. This mounting of the contact elements electric is similar to conventional mounting with two cams sliding.
  • FIGS. 5A, 5B and 5C illustrate a time-setting rod in three different possible longitudinal positions.
  • the time-setting rod is fully pushed towards inside the watch case.
  • the rotation of this rod does not cause opening and / or closing of electrical connections.
  • This position therefore corresponds to a "neutral" position of the contacts.
  • the diameter of the area cylindrical 17 implies that the electrical connections are always established. In order to minimize the power consumption due to these connections, it is it is possible to provide for the supply to be stopped if the contacts remain stationary for more than a predetermined period.
  • the time-setting rod is represented in a position slightly moved to the outside of the watch case.
  • the area helical 19 is located opposite the contacts 14, 14 '.
  • Rod rotation causes the alternative opening and closing of each connection.
  • This opening and closing generate electrical signals formed of pulses, which are used in the electronic circuit 12 of the watch so as to control different functions.
  • Signal generation same as the discrimination of the direction of rotation of the rod are discussed below with reference to Figures 7A and 7B.
  • the use of these signals for accessing watch functions, is not discussed in detail, being given that these elements are well known to those skilled in the art.
  • Figure 5C illustrates the time setting rod in a strongly moved to the outside of the watch case.
  • the helical zone 19 remains opposite the contacts 14, 14 '. So electrical signals formed pulses can again be generated by rotation of the rod, with an identical phase shift, therefore independent of the axial position of this rod.
  • FIGS. 6A, 6B, 6C and 6D The embodiment illustrated in FIGS. 6A, 6B, 6C and 6D is similar to that of FIGS. 5A, 5B and 5C.
  • the time-setting rod 13 can however be moved to four different longitudinal positions. In the position illustrated by FIG. 6A, corresponding to the position of the rod pushed towards inside the watch, the contacts 14, 14 'are arranged in an area cylindrical 17, but they are not moved by this area. In this position, the connections remain permanently open and do not consume so no energy.
  • the contacts 14, 14 ' are located opposite the helical zone 19, which, as before, allows generate electrical signals by rotating the rod.
  • FIGS. 7A and 7B illustrate electrical signals obtained during a constant speed rotation of a time-setting rod as illustrated by Figure 3A for example.
  • the duration during which each contact is closed is substantially equal to the length of time it is open. We are talking in this case of 50% duty cycle.
  • the switching of one of the contacts occurs substantially in the middle of the period during which the other contact remains in a given stable state. AT As an example, if a switch to one of the contacts occurs every 0.2 seconds, it is desirable that the switching of the other contact is each time 0.1 seconds after switching the first contact.
  • the electrical signals are said to be "in quadrature".
  • this condition is filled when the pitch of the helically developed section is such that the angle traversed circularly by a stop over a distance d is 30 °.
  • this step must be 45 °. This configuration minimizes the risk of false detection of switching, and therefore ensuring that the electrical signals will be interpreted correctly.
  • FIG. 7A illustrates for example the signals obtained during a rotation in clockwise of the time setting rod. From this figure, we can see that the transition from logical state 0 to logical state 1 of the first contact is followed by a transition from logical state 0 to logical state 1 of the second contact.
  • the present invention has many advantages over prior art devices.
  • the time setting rod 13 is made in one piece and does not include no sliding elements such as cams or sliding gears. This reduces the number of parts to be produced and considerably simplifies the assembly of the entire watch.
  • the helical zone 19 it is possible to provide for the helical zone 19 to be a regulated surface, which also simplifies the manufacture of this rod.
  • section of the helical zone 19 is large compared to the square section of the rods of the prior art. This improves robustness thanks to greater mechanical resistance for a reduced bulk.
  • the total length of the rod can also be reduced, since it is no longer it is necessary to take into account the play related to the sliding mounting of the cams. This frees up space in the watch, which is advantageous, in particular in small watches.
  • the positioning of the contacts 14, 14 'need not be particularly specific. It is enough that the distance d between the contacts agrees with the pitch of the helix of the helical area of the rod. This is particularly simple to guarantee due to the manufacturing processes generally used to make the contacts.
  • the present invention is not limited to the embodiments described, but extends to any variant or modification obvious to a person skilled in the art.
  • the shape of the helical area can be changed, provided that that it allows to move the contacts during the rotation of the rod. It is indeed possible to provide two or four helical profiles for example at location of the three profiles illustrated in FIGS. 3A to 3C. he is also possible to use only one contact if it is not necessary to discriminate the direction of rotation of the rod. This would determine a displacement in translation of the rod, since in the absence of rotation, such displacement would produce an inversion of the state of the contact.
  • the pitch of the propeller can vary along the helical zone. This would determine the axial position of the time setting rod.
  • the offset between the signal generated by one of the contacts compared to the offset of the signal generated by the other contact is different if the pitch of the helicoid in two helical zones is different.
  • signals can be quadrature when the time setting rod is in a first axial position and not be in quadrature when the rod is in a second axial position. Signal analysis would thus allow determine the axial position of the time setting rod.
