Definitions

  • the invention relates to a universal watch according to the Preamble of claim 1.
  • a universal watch known from US 4,451,159 has a rotatable outer ring, which the allows manual selection among several intended functions.
  • this ring has the underside in certain arrangement concave and convex areas that cooperate with switches housed in the watch case.
  • the states of the switches each have a specific state pattern, which is evaluated by an electronic circuit becomes.
  • this document there are solutions for the cases shown with up to twelve rotary positions. Will that be in it described teaching on, for example, twenty-four rotational positions expanded, a number of Switches that do not correspond to the minimum possible. So this solution comes as small as possible Number of switching elements and thus cost minimization not to a satisfactory extent.
  • the CH 608 323 shows a universal watch for twenty-four Time zones with a twelve dial division.
  • cams are provided, which in turn Operate the switches arranged in the watch case. Similar to in the previous case, when turning the outer ring the status of counters relative to a reference position changed. Accordingly, the problem of the Error entrainment and leakage.
  • To provide cams and switches permanent magnets and magnetic switches The arrangement of the cams and switches shown on several circular orbits close to each other can be but impossible to transfer to a magnetic solution because the distances of the permanent magnets and the magnetic switches a lot would be too small.
  • the universal clock according to the invention points the following advantages based on the state of the art:
  • each defined rotational position of the Outer ring has its own state pattern of the magnetic switches assigned, i.e. in that each set rotational position regardless of the previous rotational positions can be detected, there is no dragging one possibly in the electronic circuit of the Clockwork occurring error.
  • Permanent magnets and magnetic switches do not show any signs of wear, so that an excellent tightness can be guaranteed.
  • a first embodiment according to claim 7 through the choice of eight magnetic switches and five permanent magnets a relatively large distance between the permanent magnets before in favor of increased operational safety a better decoupling of the individual, each by to enable the permanent magnets generated magnetic circles.
  • the power consumption is the magnetic switch low, since at the same time only a maximum of two in switched on state.
  • Universal watch according to claim 9 are only five Magnetic switch, but ten permanent magnets are provided. This Solution is particularly interesting if the price of the Magnetic switch significantly exceeds that of permanent magnets.
  • the five magnetic switches according to claim 10 are arranged side by side, only a small one Requires space, making a smaller one, for example Total height of the watch can be achieved. Furthermore can be the effort in terms of electrical connection the magnetic switch with the clockwork can be kept small.
  • the magnetic switches and the Permanent magnets also referred to below as detection elements.
  • FIG. 1 shows a universal watch 10 according to the invention shown, which has a central part 11, in which underside a bottom 12 and a glass 13 on the upper side is.
  • the middle part 11 forms with the bottom 12 together a watch case.
  • the two seals 14 and 15 as well as control shaft and not shown Battery cover seals close one labeled 16 Interior of the universal watch 10 waterproof from the Outside world.
  • a with 22 designated axis of rotation corresponds to the axis of hands not shown, which together with the dial 18 are referred to as a display device.
  • Fig.1 there is a small, hermetically sealed one Switch housing 25 shown, which is in a tooth-shaped Groove 26 of the printed circuit 24 used and is glued.
  • the switch housing 25 fills the groove 26 completely and stands on the underside of the printed Circuit 24 to the clockwork 21 adjacent.
  • a magnetic switch 27e which has an elongated, fixed contact 28 and an elongated, Movable contact 29 has. Both contacts 28 and 29 are on tracks, not shown, on both sides of the printed circuit 24 with which electronic circuit of the clockwork 21 connected.
  • the magnetic switch 27e is in a first one Intersection 30, which consists of a about the axis of rotation 22nd extending first circumferential line 31 and an associated, first radius line 32 emerges.
  • the two elongated contacts 28 and 29 run at rest, i.e. if they are not exposed to a magnetic field, in essentially in the direction of this first radius line 32.
  • the magnetic switch 27e shown in FIG Magnetic field is exposed, only the fixed contact 28 in this direction, while the movable contact 29 is curved.
  • a second Intersection 35 which is concentric from a second to the first Circumferential line 36 of the same diameter and an associated second radius line 37 is formed a recess 38 is arranged.
  • a permanent magnet 39c is used and with the outer ring 33 glued.
  • the permanent magnet 39c is positioned in such a way that the radius line 37 through its two poles N and S runs, with its N-S polarity not initially must be taken into account.
  • the permanent magnet 39c is advantageously located in the immediate vicinity above the magnetic switch 27e, i.e., the permanent magnet 39c with the magnetic switch 27e connecting and through the two intersections 30 and 35 connecting line 40 runs parallel to the axis of rotation 22. Between the permanent magnet 39c and the magnetic switch 27e is a closed magnetic circuit 41 shown.
  • the universal watch 10 has according to this embodiment eight magnetic switches 27a-h on, which with the in Fig.1 shown magnetic switch 27e identical and also via conductor tracks, not shown, with the electronic Circuit of the clockwork 21 are connected.
  • Analogous the permanent magnet 39c shown is representative of a total of five permanent magnets 39a-e have been described.
  • the Arrangement of the magnetic switches 27a-h and the permanent magnets 39a-e can be seen in FIGS. 2 and 3.
  • FIG 2 is a schematic plan view of the in Fig.1 shown universal watch 10, but only from the detection elements are visible.
  • the Positions 1h-24h are therefore in relation to the housing 11, 12 immovably defined.
  • the eight magnetic switches 27a-h are in the positions 3h, 6h, 9h, 12h, 15h, 18h, 21h and 24h while moving the five permanent magnets 39a-e for the rotational position shown here of the outer ring 33 are in the positions that the Hourly marks correspond to 5h, llh, 15h, 19h and 24h.
  • There contacts 28 and 29 of magnetic switches 27a-h only then close when above them, i.e. in the same Position, a permanent magnet 39a-e is present in the rotational position shown, only the two magnetic switches 27e and closed at 27h while the remaining six magnetic switches 27a-d and 27f-g remain open.
  • FIG.2 A truth table is shown in FIG the state pattern for that shown in Fig.2 Arrangement of the eight magnetic switches 27a-h and the five Permanent magnets 39a-e for all twenty-four rotary positions of the outer ring 33 are listed.
  • each rotational position of the outer ring 33 can be independent of the or the previous ones from the electronic circuit of the clockwork 21 can be detected.
  • Figure 3 shows an illustration in the sense of Figure 2, however with a different number and distribution of the magnetic switches and permanent magnets.
  • Here are just five magnetic switches provided with the magnetic switches 27a-h from Fig.2 identical and are therefore marked with 27a-e.
  • the magnetic switches 39a-j are identical to those 39a-e of Fig.2.
  • the five Magnetic switches 27a-e are in the positions 16h-20h provided while the ten magnetic switches 39a-j on the Positions 2h, 3h, 6h-8h, 14h, 17h, 19h and 23-24h distributed are.
  • the one next to the other Permanent magnets 39a-j i.e. the permanent magnets of the two Groups of two 39a-b and 39i-j as well as those of the group of three 39c-e are advantageously opposite to each other Tru. That means, for example, the permanent magnets 39c and 39e are oriented according to FIG. 1, during the intermediate permanent magnet 39d reversed, i.e. with the N pole is directed towards the axis of rotation 22. As a result of that in this way the magnetic field strength between each Permanent magnet 39c-e becomes minimal, the underlying one falls Magnetic switch when the outer ring 33 rotates between the two corresponding defined rotary positions briefly.
  • the decision as to which permanent magnet pair is rectified must be in accordance with the design conditions be adjusted to the clock.
  • Figure 5 shows analogous to the truth table of Figure 4 for the solution shown in Figure 2 that for each of the twenty four Rotational positions of the outer ring 33 each also a clearly characterizing state pattern consists.
  • Magnetic switches 27a-e corresponds to the absolute minimum for twenty four rotary positions.
  • the small number of Magnetic switch 27a-e has a favorable effect on the manufacturing costs from, since their price is generally clear is higher than that of permanent magnets.
  • the wiring effort can be reduced, what also has a favorable effect on the manufacturing costs.
  • the display device takes over only after the crown has been pressed down briefly the local time of the selected time zone.
  • the electronic circuit reads the advantageously contains a microprocessor, the state pattern the magnetic switch 27a-h or 27a-e, is looking for this Pattern in a saved table, reads the associated, new target position of the pointer and corrected the pointer position accordingly. Because the state of the Magnetic switch 27a-h or 27a-e only open in this case Command is briefly queried, can be on its permanent Feeding can be dispensed with. Because of the magnetic switch only when the crown is depressed electrical energy is saved.
  • the universal clock 10 is continuous follows the manipulations on the outer ring 33, i.e. that the display device continuously the local time the selected time zone from the electronic circuit takes over without, as described in the previous Case, an acknowledgment must be awaited.
  • the displayed local time immediately with each change of position of the outer ring 33. After the outer ring 33 during ten seconds, for example has been, however, the display device goes back to the originally displayed local time, regardless of the rotation position of the Outer ring 33. If the crown is pressed, it takes over Display device in any case the local time of the selected time zone.
  • This solution is Mainly intended for users who use their time zone rarely leave, but often the local time of other time zones need to know to find the appropriate one For example, dial the moment for phone calls can.
  • acknowledgment can be done on a other ways, e.g. by pulling the crown or with an additional push button.
  • the magnetic switch can be interesting, one or to provide several additional magnetic switches to one To achieve redundancy.
  • the information of the additional Magnetic switches allow locking or even correcting a possible reading error. On in this way, for example, the failure of a magnetic switch determined and the watch wearer noticed be made. Otherwise the faulty state pattern the magnetic switch as a different rotational position of the outer ring 33 interpreted and the universal watch 10 indicates an incorrect local time.
  • the inventive design of a universal watch enables for a long time at low manufacturing costs reliable detection of discrete rotational positions of the outer ring without any tendency to accumulate of emerging in the electronic circuit Errors must be accepted. This solution offers optimal conditions also with regard to housing tightness.
