Definitions

  • the present invention relates to a watch, in particular a wristwatch, with an analog time display, which has at least one minute and one hour hand, and with a rattrapante mechanism, which has at least one minute rattrapante arranged coaxially with the hands of the normal time display. Has hands and / or hour rattrapante hands.
  • Such a watch is intended both to enable normal time display and to allow the measurement of time differences or the reading of time periods of different events in an effective and simple manner.
  • the prior art contains chronographs in particular, which have a guidebook function.
  • the advice trap mechanism is mostly used to temporarily stop the stop pointer during the stopping process while the measuring process continues, in order to then let it advance to the total time measured. This is the case, for example, to allow the safe reading of intermediate times, while the measurement of the end time continues for the time being.
  • the normal time display is omitted from such clocks and it is a pure stopwatch or the stop function is implemented in a separate secondary display.
  • the desired information from the information in the normal time display and the measurement of the secondary display must first be carefully calculated, and it is usually not possible to read the absolute time of the beginning or end of an event directly.
  • clocks with a normal, analog time display which have additional hands that can be brought to a desired position at a certain point in time and thus directly display the connection and the time difference with the current time.
  • document US 1 790 359 describes a device by means of which a watch with a conventional time display by means of minute and hour hands can be equipped with additional minute and hour hands in order to display the time difference between the moment an event started and the current time.
  • the additional minute and hour hands are set manually, the position of the additional minute and hour hands is therefore always stationary as long as they are not moved manually.
  • the use of such a manual device is obviously cumbersome, time consuming and troublesome when reading the time normally.
  • the patent US 5 255 248 describes a watch with the same purpose, that is, a watch which simultaneously allows both the normal time display and the measurement of a time difference, which is therefore neither a stopwatch nor a completely normal watch, but both functions in one display integrated.
  • the means used for this and above all the mode of operation are different here.
  • the watch proposed in this patent on the one hand has an additional minute hand arranged coaxially to the hands of the normal time display, which can be brought from a stationary normal position into the current position of the normal minute hand by pressing a push button. There he remains stationary to mark the beginning of an event.
  • the step of setting the additional pointer to the current time can be carried out using a conventional rattrapante mechanism.
  • the watch described has a ring which can be rotated coaxially around the dial, with a marking and a scale, for example to mark the end of the event and thus to integrate a "countdown" function.
  • the aim of the present invention is the realization of a clock both for normal time display and for the effective and simple measurement of time differences or for reading time periods of different events while avoiding the aforementioned disadvantages of the current systems, as well as the realization of a rattrapante suitable for this purpose.
  • the present invention therefore relates to a watch, in particular a wristwatch, which has the characteristics of claim 1, and a rattrapante mechanism suitable for realizing this clock with the characteristics mentioned in the claims.
  • a watch according to the invention is characterized in particular in that the rattrapante hand or hands are moved in a normal mode of the watch in synchronism with the hands of the normal time display and relative to them in an overlapping position, and that they are stopped in a stop mode for marking any point in time and after the expiry of any period of time for the synchronous run again, the hands of the normal time display can be brought back into an overlapping position relative to these.
  • this solution makes it possible to arrange the additional hand or hands in the normal mode of the watch, for example, under the hands of the normal time display, that is to say not visible from above, and to have them perform a synchronous movement, while the known ones mentioned above In contrast to this, the clock or hands in normal mode remain in a stationary position.
  • the additional hand (s) are reset by the rattrapante mechanism from their stop position to their (non-stationary) normal position in an overlapping position relative to the hands of the normal time display.
  • the rattrapante mechanism in the above-mentioned document US 5 255 248 is used in a reverse manner, so to speak, in that the additional minute hand is moved from its (stationary) normal position to its stop position by means of the rattrapante mechanism.
  • the stopping and resetting of the additional hands can be triggered via an operating element such as a push button or a rocker.
  • a status display be it by the rocker mentioned above, an explicit display window or the like, can be provided in order to inform the user of the current functional mode.
  • FIGS 1 a to 1 d schematically illustrate the principle and the functional sequence of a first embodiment of such a clock.
  • Figures 2a to 2b represent schematic views of a second embodiment of such a watch.
  • Figure 3 represents a further embodiment of a clock according to the invention, in which a rocker was selected as the operating element of the council rocket mechanism.
  • Figure 4 shows an embodiment of such a clock, which additionally has a window for status display and a ring with a scale.

  • the present invention is a watch 1, in particular a wristwatch, with an analog time display, which has at least a minute 2 and an hour hand 3. It can also have a second hand 4.
  • this watch has a minute and hour rattrapante mechanism or only a minute rattrapante mechanism or only an hour rattrapante mechanism, depending on the intended use of the watch, the different orders of magnitude of time to be measured concern and can therefore influence the above choice.
  • the rattrapante mechanism has at least one rattrapante hand arranged coaxially with the hands 2, 3 of the normal time display, usually a minute rattrapante hand 5 or an hour rattrapante hand 6, but can also have several rattrapante hands , for example, in addition to the minute rattrapante hand 5, also an hourly rattrapante hand 6, which is also arranged coaxially, or even a second rattrapante hand.
  • the present mechanism is inserted into a normal watch, for example a wristwatch, so that the normal time display and the measurement of a time difference with the help of the rattrapante -Mechanism can be done simultaneously in a single display.
  • the minute or hour rattrapante mechanism could be identical to known versions of a rattrapante mechanism for chronograph double hands.
  • a rattrapante mechanism is For example, explained in more detail in patent application EP 0 562 155, so that a description in this regard need not be repeated here.
  • the mechanism is advantageously implemented by one of the embodiments of such a mechanism described in more detail below, since these both reduce the height of the movement and thus the height of the watch as well as improve the accessibility of the individual components of the rattrapante mechanism, for example in the event of maintenance or repair.
  • a (minute) rattrapante mechanism is generally similar to that of known rattrapante mechanisms.
  • the present mechanism is characterized by a different composition and arrangement of the parts or assemblies of the mechanism.
  • the non-positive coupling of a rattrapante mechanism according to the invention is not, as in known rattrapante mechanisms, in the center of the pointer mechanism, but outside next to the pointer mechanism.
  • the minute rattrapten mechanism mainly consists of three assemblies, namely a blocking device 20 (Fig. 5) with a slide 21, a spring 22 and pliers 23, a reset device 30 including a heart gear 31 (Fig. 8a) and a reset lever gear 33 (Fig. 8b) with clutch and a pointer mechanism 50 (Fig. 5, 9a, 9b and 12), which houses parts or associated wheels of the mechanism.
  • the slide 21 is guided by means of, on the one hand, an elongated recess and a sleeve 26 and, on the other hand, two adjustable eccentrics 24a, b or, as an alternative, two fixed pins which are attached to the work plate 15 to the right and left of the slide 21 ,
  • the slide 21 can be brought straight into one of two positions 21 a, b, a drawn position 21 a with open pliers ends 23a, b (see FIGS. 6a and 6b) and a pressed position 21 b with closed Plier ends 23a, b (see Fig. 7a and 7b).
  • the movement of the slide 21 (FIGS.
  • the pliers 23 causes the pliers 23 to be opened and closed by a pin 21c attached to the end of the slide 21 which is directed into the housing interior, on narrowing lateral inner surfaces 23e of the shorter pliers ends 23c and 23d of the pliers Pliers 23 slide along.
  • the curved shape of the narrowing inner side surfaces 23e of the shorter pliers ends 23c and 23d forms a kind of cam which creates a pressure point in order to prevent uncontrolled displacement of the pin 21c by external impacts.
  • a spring 22 is placed by means of the screw 25 and / or other fastening elements in such a way that their outwardly facing ends with pins 22a, b on the outer sides of the shorter pliers ends 23c and Press 23d and thereby force to open the longer pliers ends 23a, b of the pliers 23.
  • the spring 22 also limits the height play of the slide 21 in the area of the screw 25 (see Fig. 9b).
  • the closing wheel 55 In the depressed position 21 b of the slide 21, the closing wheel 55 is thus blocked against its rotation by the closing of the pliers 23, while it can rotate freely in the drawn position 21 a of the slide 21.
  • the non-positive coupling arranged coaxially to the axis 58 of the pointer mechanism 50 consists of a reset device 30.
  • This has two subassemblies and, as will be explained later, works with one further subassembly suitable for this purpose or corresponding parts of the rattrapante mechanism arranged in the pointer mechanism 50.
  • the first sub-assembly of the reset device 30 has a heart wheel 31 with a heart 32 fastened thereon
  • the second sub-assembly has a reset lever wheel 33 with a lever spring 34, a lever 35 and a roller 36 (variant 1) or a sliding block 37 (variant 2).
  • the variant with the sliding block 37 is rather loud for the reset device assembly Figure 8d is preferred because the flat surface of the sliding block 37 can lie completely on the "heart valves" or shoulders of the heart 32, which is equivalent to a 2-point support. The latter is more stable than a 1-point support in the case of roller 36 in the variant according to Figure 8c.
  • a helical eccentric could also be used. However, this entails a disadvantage in the pointer position via the winding shaft and the crown, which in this case can only be done in one direction.
  • the basic structure of the pointer movement 50 in the center of the clockwork roughly corresponds to that of a classic world clock, as shown in Fig. 9a, but contains additional parts belonging to the rattrapante mechanism.
  • the lowest level has a minute tube 51 with a minute tube wheel 52 mounted thereon, the minute tube 51 carrying the minute hand 2.
  • the middle level houses the parts of the rattrapante mechanism that carry the rattrapante pointer (s) 5,6 and interact with the non-positive coupling. These are a minute towing pointer tube 53 carrying the minute towing pointer 5 with a minute towing pointer wheel 54 mounted thereon, which is also called an indicator wheel, a stop wheel 55 being attached to the latter in such a way that it is at the level of the aforementioned pliers 23, insofar as the pliers 23 are as mentioned grips the stop wheel 55 on two sides.
  • the top level has an hour tube 56, which is riveted, for example, to the bridge 17 lying below the upper bridge 16 and serves as an axis of rotation for an hour wheel 57, the hour wheel 57 carrying the hour hand 3 on its tubular part.
  • the pliers 23 or their longer ends 23a and 23b were mounted in height so that they span the stop wheel 55 on two sides and keep the minute drag pointer wheel 54 connected to it and having a larger diameter in suspension.
  • the minute trailing pointer wheel 54 thus rests on the longer tong ends 23a and 23b without touching on the upper side the hour tube 56 attached to the bridge 17 on its lower part and without being supported on the lower part on the upper part of the minute tube 51.
  • the minute tube 51 is freely rotatable and the daily movement of the watch is not disrupted by additional friction on other parts.
  • the minute trailing pointer wheel 54 In the event of an axial impact upward, the minute trailing pointer wheel 54 abuts the hour tube 57, and in the case of an axial impact downward, the two pins 23f can be supported on the work plate 15 on the longer ends 23a and 23b of the pliers. In so far as the tong ends 23a and 23b have been shaped as springs, after a possible impact they push the minute trailing pointer wheel 54 back into the starting position. In the event of a radial impact, the pliers ends 23a and 23b yield, in extreme cases abut the inner wall 52a of the minute tube wheel 52 provided with a recess on its upper side at the level of the toothing, and are thus stopped.
  • the spring 22 described above presses the pliers 23 back into the starting position by means of the pins 22a and 22b which engage the shorter pliers ends 23c and 23d.
  • the hour wheel 57 lies on the bridge 17 and thus has no influence on the lower wheels in the pointer mechanism.
  • the hour wheel 57 is driven in the usual way via the change wheel 59, as shown in FIG. 9b.
  • the stop wheel 55 is blocked by the pliers 23 after actuation of the operating element 7, the minute drag indicator wheel 54, which is fixedly connected to the stop wheel 55, and the reset lever wheel 33 which is in engagement therewith are opposite blocked from rotation, so that the minute trailing pointer 5 is stopped.
  • the minute tube wheel 52 and the hour wheel 57 are still driven by the change wheel 59, so that the minute and hour hands 2, 3 of the normal time display continue to rotate normally. This creates a relative rotation between the heart gear 31 and the blocked reset lever gear 33 so that, as illustrated in Figures 8c and 8d, the side surface of the heart 32 during its rotation against the restoring force of the lever spring 34 on the roller 36 attached to the lever 35 or the sliding block 37 acts.
  • the hour rattrapante mechanism works in an analogous manner to the minute rattrapante mechanism described above. The differences in structure are shown in Figures 10 and 11 and 9 and 12.
  • the blocking device 20 remains unchanged.
  • the reset device 40 for the hourly drag indicator 6, which is constructed in the same way as that described above, was made for reasons that will be apparent later, in comparison to that described above Reset device for the minute trailing pointer 5 attached to the opposite side of the movement 60, as shown in Figures 10 and 11.
  • the structure of the pointer mechanism 60 in the center of the clock is shown in the section of FIG. 12 in the case of an hour rattrapante mechanism.
  • the wheels are separated from one another by a safety distance so that the torques, for example that of the hourly drag indicator 64 or the date setting wheel 66, have no influence on the neighboring wheels.
  • the individual functions of the watch are not disturbed by uncontrollable friction effects with other parts.
  • the pointer 60 can be explained in levels. On the lowest level is the minute tube 61, which carries the minute hand 2 as in the previous case and is driven by the change gear 69. This also drives the hour wheel 62, which is located on a middle level and carries the hour hand 3. The free rotation of the hour wheel 62 above the minute tube 61, which does not have a minute tube wheel here, is ensured by the resting of the hourly drag indicator wheel 64 located in the plane above it on the pliers 23. This hourly drag pointer wheel 64 is attached to the hourly drag pointer tube 63, which carries the hourly drag indicator 6 and rotates concentrically in the hole of the tube 67 riveted on the bridge 17 with a small amount of play.
  • the height play of the hourly drag pointer wheel 64 is limited at the bottom by the two longer pliers ends 23a and 23b and at the top by the lower part of the tube 67 riveted in the bridge 17, as can be seen in FIG.
  • the date setting wheel 66 located in the upper level and also driven by the change gear 69 belongs to the date mechanism. It was shown in Figure 12 to illustrate its separation from the hour drag pointer wheel 64.
  • the date setting wheel 66 lies on the bridge 17 and rotates concentrically with a slight play around the firmly riveted tube 67 variable torques of the date mechanism have no influence on the hourly drag indicator wheel 64 located below.
  • the pointer mechanism is staggered around a central bearing tube attached coaxially to the axes 58 and 68, and all the wheels outside the pointer mechanism 50/60 or outside the center of the clock are advantageously mounted on bearing stones, as indicated in the sectional views.
  • the minute and hour rattrapante mechanism shown in Figure 13a is created by combining the minute rattrapante mechanism shown in Figure 10 with the hour rattrapante mechanism shown in Figure 11. Due to the advantageous arrangement of the reset devices on radially opposite sides of the movement this combination of the two rattrapante mechanisms according to the invention described above for the Minutes and an easy task for the hours. At the same time, this constellation illustrates the advantages of a mechanism according to the present invention, since the saving in work height is very clear. In addition, the modularity of the mechanism becomes clear, which enables the separate access to the individual, separate assemblies for separate maintenance or repair.
  • the gradation in section, from bottom to top, can look in detail as follows, for example: In the first level, the minute tube 51 with the minute tube wheel 52 is located, in the second level the minute drag pointer tube 53 with the minute drag pointer wheel 54 and the stop wheel 55, in the third level the newly inserted bridge and the hour wheel 62, in the fourth level the hour drag pointer tube 63 with the hour drag pointer wheel 64 and the associated stop wheel 65 and in the fifth level the bridge 17, the date setting wheel 66 and the bridge 16.
  • the pliers 23 are designed and placed in such a way that they act on both stop wheels 55 and 65 simultaneously on the corresponding levels. As described above, the two resetting devices 30 and 40 are in engagement with the corresponding wheels of the pointer mechanism 50/60 and are therefore arranged at a corresponding height at their radial position around the pointer mechanism.
  • this minute and hour rattrapante mechanism is also in this variant in complete analogy to the previously explained, so that in the present case, both the minute hand 2 and Hour hands 3 have an associated double or trailing hand 5 or 6, which are either moved or stopped in an overlapping position relative to the hands of the normal time display.
  • the movement height is slightly higher than in the case of only a rattrapante function, but this is due to the non-coaxial arrangement (according to Figure 13a) of the reset devices 30 and 40, which would otherwise be in the pointer movement and would increase the movement height accordingly, compensated, which makes the advantage of a mechanism according to the invention particularly clear.
  • the individual assemblies are also extremely easy to access due to their radial arrangement around the pointer mechanism and can therefore be handled separately in the event of maintenance or repair.
  • Figure 13b shows a variant of the minute and hour rattrapante mechanism, in which the reset device 40 controls the hourly drag indicator wheel 64 for the hours and, via the change gear 59a, the minute drag indicator wheel 54 simultaneously.
  • This change gear 59a like the reset device for the hours, advantageously takes a position radially outside of the hand mechanism arranged in the center of the watch and functions in the opposite way with regard to the flow of force in comparison with the traditional change gear 59.
  • the reset device 40 for the hours first controls the hourly drag pointer wheel 64 as described above, and this is in engagement with the drive of the change gear 59a for the minute double pointer 5.
  • the wheel of this change gear 59a is in engagement with the minute drag indicator wheel 54 and as a result of this the speed of rotation is translated, the synchronous movement of the minute double hand 5 and the hour double hand 6 or the simultaneous stopping of these hands.
  • the translations do not change in a mechanism according to the invention in comparison with a traditional pointer mechanism.
  • the clock 1 has an operating element 7, such as one, for controlling the rattrapante mechanism or the associated rattrapante hands 5, 6 Pusher 7a, which is arranged independently of the crown 8 of the watch on the edge of the case of the watch.
  • the operation of the rattrapante mechanism by the associated operating element 7 or the interaction of these two components takes place in a conventional manner.
  • a first actuation of the control element 7 causes the minute and / or hour rattrapante hands 5, 6 to stop at their current position; further actuation of the control element 7, which is possible at any time, brings the hand (s) 5, 6 back into congruence with the Minute and / or hour hand 2,3 of the normal time display for synchronized running with them again.
  • the functional sequence for measuring time differences or reading time periods of different events by means of the clock 1, which in this example has a minute and hour rattrapante mechanism is as follows.
  • the minute and hour rattrapante hands 5,6 during normal movement of watch 1 are preferably, not visible from above, below the minute and hour hands 2, 3 of the analog time display, which are symbolic with are marked with a rectangle and rotate synchronously with them.
  • the minute and hour rattrapante hands 5, 6 could also be attached above the minutes or hour hands 2, 3 of the analog time display, insofar as the overlapping relative position of the hands 2, 3 and 5, 6 and their synchronous movement are important is.
  • the minute and hour rattrapante hands 5, 6 form a kind of double hand in the normal mode of the watch with the hands 2, 3 of the normal time display.
  • the minute and hour rattrapante hands 5, 6 shown as white hands are, as shown schematically in Fig. 1 b, stopped by their first actuation of the operating element 7 at their current position, which is symbolically represented by the arrow "stop" , while the minute and hour hands 2,3 of the analog time display continue to rotate. Their movement is symbolically indicated with lines and arrows.
  • Fig. 1 c shows the same constellation as in Fig. 1 b after several hours. It can be clearly seen that the minute and hour rattrapante hands 5,6 set the time of an event start in relation to the current time, which is indicated by the minute and hour hand 2, 3 of the normal time display. The relationship between these two times and the corresponding time difference can be read off in a single display, as well as, in particular, the corresponding absolute times.
  • the stopped minute and hour rattrapante hands 5, 6 can finally be shifted at any time by further actuation of the operating element 7 under the minute and hour hands of the normal time display in order to measure the time difference to end since the beginning of the event.
  • This process is symbolically represented by the arrow "reset"; the stop position of the hands is symbolically marked with dash-dotted lines and the direction of movement with arrows.
  • FIGS. 2a and 2b show a watch with the same functions as described above, but in one embodiment with only one minute rattrapante mechanism, that is, without hour rattrapante hand 6.
  • the views correspond to figures 1a and 1c, the entire functional sequence is analogous to that described above.
  • minute and hour rattrapante hands 5,6 always rotate congruently and synchronously with the minute and hour hands 2, 3 of the normal time display in a watch 1 according to the invention when not stopped. This is also the case when setting the hands 2, 3 of the normal time display.
  • a rocker 7b is attached as an operating element 7 to the clock 1 instead of a pusher, at the position of which the function mode can be read. If the rocker 7b is pressed into the lower position, the clock 1 is in the "reset” function mode, the normal mode, that is to say the minute and hour rattrapante hands 5, 6 rotate congruently and synchronously with the hands 2, 3 time display. If the rocker 7b is pressed into the upper position, the clock 1 is in the “stop” function mode, the stop mode, that is to say the minute and hour rattrapante hands 5, 6 are stopped while the other hands 2, 3 continue to rotate ,
  • This embodiment has the advantage that the function mode of the clock 1 is displayed directly by the position of the control element.
  • the function mode of the clock 1 can, as shown in FIG. 4, also be displayed with the aid of a disc 10 visible through a window 9 in the dial of the clock 1, which has the same function as the rocker 7b of FIG. 3.
  • the pane 10 is rotated by actuating the pusher 7a or the rocker 7b, so that a sector of the pane 10 corresponding to the current functional mode is visible through the window 9.
  • the disk 10 is designed accordingly for this, depending on the rotation angle caused by the actuation of the operating element, which can be selected in various ways, and on the good legibility of this display.
  • the display of the function mode is useful insofar as, for example, in certain applications of the watch 1, such as during diving, a status display is recommended for safety reasons.
  • the clock 1 shown in FIG. 4 also has a rotatable ring 11 which is arranged coaxially to the axis of the hands of the analog time display and which can be implemented either as an inner or outer ring. In the case of an outer ring, this can be rotated manually; in the former case of an inner ring, the watch 1 has a conventional device, which can be integrated, for example, in the operating element 7 or in the crown 8 in order to rotate it of the ring.
  • the ring 11 has a scale, which preferably has divisions into ranges of 10, 5 and 1 minute with corresponding inscriptions, which can be designed in various ways, and can also have a marking, for example in the form of an arrowhead or a, for example fluorescent, dot, exhibit.
  • the ring 11 is useful, for example, for reading the duration of an event directly by rotating the zero of the ring scale to the time of the start of the event, or for specifying a desired time for the end of the event and explicitly using the ring 111 marking to display on clock 1.
  • a clock 1 with minute and hour rattrapante mechanism according to the present invention is suitable for easily reading the elapsed time since the start of a certain event. Because by means of an operating element 7 such as a pusher 7a or a rocker 7b on the housing, the time indicated by minute and hour rattrapante hands 5, 6 is stopped at the moment an event begins, while the minute and hour hands 2, 3 of the normal time display keep turning.
  • an operating element 7 such as a pusher 7a or a rocker 7b on the housing, the time indicated by minute and hour rattrapante hands 5, 6 is stopped at the moment an event begins, while the minute and hour hands 2, 3 of the normal time display keep turning.
  • the wearer is reminded when, for example, a device was switched on, when work started, when a trip started, or when a break is necessary, etc.
  • such a watch 1 can be used as an alternative to a classic chronograph for purposes similar to this or during dives, for example during a decompression phase.
  • a watch according to the invention can therefore be characterized mainly by the following features.
  • a minute and / or hour rattrapante mechanism is integrated in the watch.
  • the normal time display of the watch remains unchanged.
  • the minute and / or hour hands of the rattrapante mechanism move in the normal mode of the watch in an overlapping position relative to the hands of the normal time display and are synchronized with these hands, thus forming a kind of double hand with the latter, while in stop mode they remain in their position show the time of an event start.
  • the control of the stopping and resetting of the hands of the rattrapante mechanism is carried out by means of an operating element such as a pusher or a rocker.
  • the function mode can be displayed using this rocker or a pane visible through a window.
  • the watch can have a ring with a scale and / or a marking.
  • the primary object of the present invention is achieved to allow the normal time display and the measurement of a time difference simultaneously, in direct mutual connection, and in an effective and simple manner, the normal time display not being adversely affected by their presence when the additional hands are not in use ,
  • the rattrapante mechanism which is advantageously used for this is characterized by a reset device which is not arranged coaxially relative to the axis of the pointer mechanism, as a result of which the movement height is reduced and the modularity of the watch is increased.
