Technical field of the invention

The invention relates to a timepiece having an hour disc rotatable about an axis and having a minute disc rotatable about the same axis for indicating the time of day. It may be a clock with an annular body, which is filled in the middle either empty or with a transparent or other not related to the clock function element.

State of the art

Watches, in particular watches with an annular body are known from the prior art. The GB 2,162,663 shows an annular body having either a through opening inside, as shown in the Fig. 1 there, or in which a jewelry insert (there Fig. 13 to 20) may be provided. The display is realized in the local Fig. 7 as a window with rotating number discs, while the local Fig. 10 shows two rotating rings, which has a corresponding optical element at the time indicating points.

EP 0 507 097 shows a similar clock with a special arrangement of the work.

EP 0 389 732 uses a digital disc for the hour display, that is to say an hour disc with the numbers 1 to 12. This disc rotates in unison with a minute disc and the current hour is displayed in a window of the minute disc, this window simultaneously displaying the minute disc Pointer for the minutes to be displayed analogously. Summary of the invention

Based on this prior art, the invention has the object, a clock of the type mentioned in such a way that in addition to the reading of the current time and the display of hour and minute information for another adjustable time information is possible.

The object is achieved according to the invention for a clock according to the preamble of claim 1, characterized in that rotatable, adjustable display elements are provided about said axis, said with the said display elements can be pointed to the said time.

These other display elements allow the display of hour and minute information for another adjustable time information.

The hourglass and / or the minute disc may be substantially full discs, with the inner disc being the smaller disc and the outer disc being the larger one located below the smaller disc. The term disc is also to be understood as meaning a ring which rotates about the said axis, for example guided correspondingly at its edges, so that the hour ring and the minute ring can be arranged next to one another.

Advantageously, these rings or discs are provided with numbers or number symbols for the digital display of the time. In a preferred embodiment, said display elements each comprise an annular disc with a window. This disc with fenter is rotatable together with the hour or minute disc for setting the further time, while the watch drive rotates said hour or minute disc relative to the disc with window. In this case, this rotation is advantageously indexed in the sense that the hourly disc advances only 1/24 of the circumference every hour, while the minute disc is advanced by 1/60 of the circumference every minute, when every minute a number can be represented in the window. It will be apparent to one skilled in the art that he can provide corresponding other indexing drives.

In another advantageous embodiment, the hour disc and the minute disc are provided with indicators for displaying the time. In contrast, the display elements each comprise a display symbol which can be set to a specific radial ray of the hour or minute disc. The indicators may include numbers or number symbols, but also interval divisions between any two numbers or number symbols. The display elements which can be set on a radial beam are, according to a design, hour hands, minute hands and, if appropriate, seconds hands, starting from said axis. The adjustability on the radial beam, for example, be at an angular distance of 6 degrees, so one setting per minute in a circular display.

Finally, the display elements which can be set on a radial beam can comprise annular display symbols which cover at least a part of the respective pane or adjoin it. This means that it may be to the discs abutting pointer sections with a dash symbol or a hint triangle, or a radial sweeping the said discs displays. This makes it possible, in principle, to display the minutes analogously, which means here that the display symbol is not aligned in each case exactly on a number or a number symbol, but, for example, every minute on the said interval divisions is indexed.

In another embodiment, a second disk rotatable about the same axis for indicating the time of day is additionally provided with a further, adjustable display element rotatable about the said axis. In addition to the possibility not mentioned here of providing a third second display in isolation, that is to say a conventional second hand for the current time, a second hand can also be provided, the display of which, as in the case of the windows, can be set according to the main claim.

The hour disc and the minute disc can be rotated in opposite directions and preferably labeled in the circumferential direction in the opposite sense, as shown for example in FIGS. 3 and 14 show.

The hour disc and the minute disc can also be readably inscribed in the radial direction, as shown for example in FIGS. 6, 9, 10 and 16.

In one embodiment, the hourly disc is the innermost disc opposite the minute disc and optionally the seconds disc.

Finally, the hour disc, the minute disc and the adjustable display elements may be annular and the watch may have a continuous opening in the region of the said axis, so that said axis does not comprise a physical shaft, but all drive elements for the different discs and the display elements on the then toroidal Corpus of the clock are provided. Further advantageous embodiments will become apparent from the drawings and the associated description, without any limitation to the existing claims applicant side is provided.

Detailed description of embodiments of the invention

The embodiments essentially show two different versions of watches according to the invention. These are watches with minute and hour hands according to a first embodiment and these are watches with minute and hour window according to a second embodiment.

The invention is based on the one hand on the insight that a clock, such as a wristwatch, pocket watch, wall clock, etc., has two hands that are fixed or rotationally adjustable and turn the numbers on two rings. In a second-ring version, there may also be three rings. In the clock of Fig. 1, not the hands 72, 73, but the hour differential ring 70 and the minute-number ring 71 rotate. The pointer positions minute hand 72 and hour hand 73 are arbitrary. For example, the pointer position can be set to serve as a reminder of an appointment. The exact time is read in extension and opposite the pointer ends 72, 73. The setting of Fig. 1 can thus serve as a reminder to 14:50 clock, the current time is 12:30. The setting of the long pointer to the position 45 degrees before the upward direction and the shorter pointer to the position in the direction of the crowns (ie 90 degrees to the right with respect to the visual axis on an applied or correspondingly suspended clock) is freely selectable for the user, wherein the selected position preferably locks in a manner that avoids accidental twisting sure.

In the case of the clock according to FIG. 17, that is to say according to a modified first exemplary embodiment, it is likewise not the hands 72, 73, 77 but the hour differential ring 70, the minute-number ring 71 and the second-number ring 79 that rotate.

Pointer positions minute hand 72, hour hand 73 and second hand 77 are freely selectable. The exact time is also read there against the pointer ends 72, 73, 77. In the following text, the clock hands are called a clock according to a first embodiment of the invention.

The clock according to Fig. 2 corresponds to the second embodiment and has no hands, but a minute window ring 72 and a hour window ring 73. In this clock, the hour differential ring 70 and the minute-number ring 71 rotate. The position of the window, minute window ring 72 and hour window ring 73 are arbitrary , The minute and hour windows of Fig. 2 thus assume the same function as the hour and minute hands of Fig. 1; they indicate where the time is to be read. The exact time appears in the windows, minutes 93 and hours 94.

The clock of FIG. 18 also has no hands but a minute window ring 72, an hour window ring 73 and a second window ring 78. In this clock, the hour differential ring 70, the minute differential ring 71 and the second differential ring 79 rotate. The position of the window, minute window ring 72 , Hour window ring 73 and second window ring 78 are freely selectable by rotating the rings relative to the clock body specified by the clock band. For other watches than wristwatches then exist corresponding housings which can be suspended or set up. The exact time appears in the windows, minutes 93, hours 94 and seconds 95. In the following text, the clocks with the penster rings are each called a clock according to a second embodiment of the invention.

A clock according to a first embodiment of the invention will now be described in detail. This has two pointers 72, 73, which can be set to any, but then fixed location. The exact time is read on an inner 70 and an outer 71 digit ring. The inner digit ring 70 indicates the hours, compared to the fixed hour hand 73. The outer digit ring 71 indicates the minutes, compared to the fixed minute hand 72. The clock can also be equipped with a second hand 77, it turns as in a conventional Clock, ie one revolution per minute. The exact second time can be displayed on the housing edge 80.

The seconds division is more marked 81 every five seconds, (1/12 turn, corresponding to one hour) and is e.g. marked with small dots 82 between the five second sections. The two digit rings 70, 71 rotate counterclockwise or clockwise. The hour differential ring 70 makes 1/12 revolution per hour and the minute differential ring 71 makes one revolution per hour.

The numbers on the two rings 70, 71 may be parallel or orthogonal to the arc, which may be Arabic or Roman numerals or other symbols indicative of clock times.

The clock according to FIG. 17, that is to say according to a modified first exemplary embodiment, has three hands 72, 73, 77, which are connected to one another. lovely, but then fixed place can be adjusted. The exact time is read on an inner 70, a middle 71 and an outer 79 digit ring.

The inner digit ring 70 indicates the hours relative to the fixed hour hand 73. The middle digit ring 71 indicates the minutes against the fixed minute hand 72. The outer digit ring 79 indicates the seconds against the fixed second hand 77. The three digit rings 70, 71, 79 rotate counterclockwise or clockwise. The hour digit ring 70 makes 1/12 revolution per hour, the minute digit ring 71 makes one revolution per hour, and the second digit ring 79 makes one revolution per minute.

The numbers on the three rings 70, 71, 79 can be parallel or orthogonal to the arc, which may be Arabic or Roman numerals. According to the first embodiment discussed above, the use of any other symbols is conceivable.

The function of a clock according to a first embodiment of the invention of FIG. 1 will be explained in more detail. The clock according to a first embodiment of the invention can for example be driven by an electronic drive as shown in FIG. 13 according to US 3,712,046 dill. The dial rings 70, 71 are driven by a gear from the stepper motor. This watch may for example have two crowns to adjust the position of the annuli 70, 71 and the hands 72, 73. In addition, the clock can be equipped with an alarm function, as indicated in Fig. 14. In the middle of the two crowns, a button 74 can be added at the 3 o'clock position, which switches the alarm function on and off. Another option for activating the alarm would be to use the keys 85 or 87. Setting the alarm time is set with the two adjustable hands 72, 73. As orientation of the hour setting there is a stronger mark 81, 12 o'clock 83 on the edge of the case every hour (1/12 turn). Alarm time can be an appointment, appointment, alarm time etc. When the alarm time is turned on, alarm icon 96 will display an LCD Liquid Crystal Display LCD, which may be a small alarm bell, as in a conventional clock. As an example, Fig. 14 shows the alarm time at 3 o'clock. The time is in the illustrated position 1 o'clock 37 minutes and 30 seconds.

The crown 85 has two positions: the crown position 1 (Fig. 4, 88) adjusts the minute-number ring 71, hereby can the time

(Minutes) can be set exactly. At the same time, when the crown is pulled out, the second hand 77 (only in the version "watch with second hand") moves to 12 o'clock position 83, ie to zero seconds.This function allows the exact time to be set Fig. 4, reference numeral 89, adjusts the hour differential ring 70, hereby can the time

(Hours) can be set exactly. With these functions, the movement continues to run normally in the background.

For setting the displays, two crowns 85, 87 are provided in a clock according to a first embodiment of the invention, wherein both crowns can take two positions when pulling out. This is shown in FIG. 4 by reference numerals 88 and 89 and in FIG. 5 by reference numerals 90 and 91. There are two ways to set the displays: 1. Time setting, 2. Hand setting.

For setting the time with the crown 85, the minute-number ring 71 is set here at position 1 (FIGS. 19, 88), and the toothed wheel Z 3 engages with the toothed wheel Z 1, which meshes with the toothed rim Z 5 of FIG Minutenzifferringes is connected. Z 1 is in turn connected to the clockwork gear and thus moves the hour differential ring 70 via the gear Z 2 in the ratio 1:60, as in a conventional clock. One turn of the minute differential ring equals 1/12 turn of the hour differential ring.

As an illustrative example, consider the following: If the minute hand ring is set to 60 minutes from the minute hand (full hour), the hour hand ring must point to one digit from the hour hand.

In position 2 (FIGS. 19, 89), the hour differential ring 70 is set, and the toothed wheel Z 4 engages with the toothed wheel Z 2, which is connected to the toothed rim Z 6 of the hour differential ring. On the axis of Z 4 it has a snap mechanism, which only turns Z 4, if the hour differential ring to a full hour (1/12 turn on the digit ring) to move. With this mechanism it is guaranteed that the hourly differential ring only adjusts by one full hour.

As another example, if the hour differential is adjusted at 4:40 to 7:40, the hour differential must be adjusted by 3/12 turn.

17, setting the time with the crown 85 is the same as in the above example except that the second differential ring 79 goes to 60 seconds ("zero" position) when the minutes are set the time can be set to the second.

For setting the pointer positions with the crown 87, the minute hand 72 is here (FIGS. 5, 90) set to any, but then fixed location and (FIGS. 5, 91) the hour hand 73. posed. If one of these two hands is misaligned, the corresponding hour difference ring or minute ring must run along with the currently matching digits, ie the time remains correct when the hands are moved, the movement continues to run normally in the "background." For these "hand setting functions" a conventional mechanism are used, however, must, as mentioned above, to run with the respective adjustment of a pointer of the corresponding number ring, since the time is not adjusted, but only the position.

In Fig. 17, this is about adjusting the pointer positions with the crown 87, the same as above, except that three positions are needed here: a position of the second hand, a position of the minute hand, and a third position of the hour hand. If one of these hands is misaligned, as mentioned above, the corresponding number ring must run with the currently matching digits.

In another example, FIG. 14 will be explained. In this clock, the hour differential ring 70 and the minute number ring 71 rotate counterclockwise. The time is 1 clock 37 minutes and 30 seconds. The alarm is set to 3 o'clock 00 minutes. In this example, when the minute hand 72 or the hour hand 73 is moved to another location (for example, a new alarm time, the minute ring 71 and / or the hour ring 70 must go along, it is still 1 hour 37 minutes and 30 seconds Movement continues in the "background" and if, for example 40 seconds have passed setting after completion of the setting the minute different ring 71 against the minute hand 72 to 38 minutes (plus 1/6 of a minute distance = 10 seconds, because the minute ring 71 continuously The second hand 77 is opposite the edge of the housing to 10 seconds, ie 1/6 Um- turn.

A timepiece according to the first embodiment of the invention can be constructed in various ways. Fig. 1 shows the clock in the version with Arabic numerals on the minute and hour digit ring, arranged parallel to the circular ring with second hand and alarm function. Fig. 3 shows the clock in a version with Arabic numerals on the minute and hour digit ring, arranged parallel to the circular ring, without second hand and without alarm function. The time shown is 12:30. Figure 6 shows the clock in the version with Roman numerals on the minute and hour digit ring, arranged orthogonal to the annulus, including a second hand. The time shown is 12 o'clock 30 minutes 00 seconds. Figure 9 shows the clock in the version with Roman numerals on the minute and hour digit ring, arranged orthogonal to the annulus, including the second hand, but the hands are set at a different position; it is still 12 o'clock 30 minutes 00 seconds , Fig. 10 shows the clock, same as in Fig. 6, but without second hand. Fig. 14 shows the clock with Arabic numerals on the minute and hour dial arranged parallel to the annulus, with second hand and an alarm button at 3 o'clock position. The "alarm time" is 3 o'clock 00 minutes The time shown is 1 o'clock 37 minutes and 30 seconds.

Fig. 16 shows the clock in rectangular shape, with Arabic numerals on the minute and hour digit ring, arranged orthogonal to the annulus, with second hand and alarm function. The hour and minute dial turns counterclockwise. The time shown is 3:30 30 minutes 15 seconds. The alarm is set to 12 o'clock 50 minutes.

In the clock of Fig. 2, the two hands of a clock after Fig. 1 replaced by two window rings 72, 73. They perform essentially the same function. The clock according to the second embodiment of the invention has two rings with openings

(Window), where at the outer ring 72 the minute 75 is displayed. The inner ring 73 displays hour 76. The inner circular surface (Kreiskδrper) 86 includes the movement. This watch need not include a hollow body such as in Patent No. GB 2,162,663A. The clock requires four movable circular rings, each two circular rings 72, 73 are provided with "windows" 93, 94 and two circular rings 70, 71, which are provided with minute-75 and hour-76 digits This clock can also be used with a second hand 77, same as the clock according to a first embodiment of the invention The two window rings 72, 73 with the "windows" 93, 94 can be positioned at any, but then fixed location. The window rings 72, 73 are mounted superimposed over the hour differential ring 70 and the minute number ring 71. The hour differential ring 70 and the minute number ring 71 rotate clockwise or counterclockwise. The circular surface 86 can be used as jewelry or advertising space. The exact time is read on an outer 93 and inner 94 digit ring window. The inner digit ring 70 indicates the hours, compared to the fixed hour window 94. The outer digit ring 71 indicates the minutes, compared to the fixed minute window 93. The clock according to a second embodiment of the invention can also be equipped with a second hand 77, he turns like a conventional clock. The exact second time is displayed on the edge of the case. The second division is every five seconds

(1/12 turn) is marked 81 more heavily and has, for example, only small dots 82 between the five second sections. The two digit rings 70, 71 rotate counterclockwise or clockwise, with the hour differential ring 70 moving only at the hour of the hour to the next hour, ie the number of hours 76 stops relative to the hour ring window 94 until the full hour has expired. This does not necessarily have to be the case with the minute differential ring, ie this ring can move continuously. However, it is advantageous if the minute-number ring moves only every full minute by 1/60 turn, thus ensuring that thus always whole digits in the window 93 are visible. As an example, the clock of Fig. 2 indicates the time 3:45 minutes 00 seconds. The hour differential ring 70 with the numeral 3, reference numeral 76, is compared to the fixed hour window 94 stand until 3 clock 59 'and then moves at point 4 o'clock 00' to the next digit, in this case to the number 4, in which case the minute differential ring 71 against the minute window 93 to (60 minutes) respectively 00 (as a display) has run. It is now 4: 00 minutes. The minute-ring 71 with the numeral 45, reference numeral 75, remains in the "window" 93 until a full minute has elapsed and then moves to the next digit, in this example at 46.

The second hand 77 here, at the exact time 3:45, points to the 12 o'clock position 83, second "zero", as in a conventional watch The numbers on the two rings 70, 71 can be parallel or orthogonal to the arc. Arabic numerals are better: the Roman numerals are disadvantageous in this clock because the individual minute digits would look rather complicated (eg 48 would be Roman XLVIII).

The clock shown in Fig. 18 has three window rings 72, 73, 78 with the "windows" 93, 94, 95 which can be positioned at any but fixed location middle 71 and an outer digit ring 79. The inner digit ring 70 shows the hours in the "window" 94 in relation to the fixed hourly window ring. The middle digit ring 71 points in the "window" 93 The minute digit ring 79 in the "window" 95 shows the seconds in relation to the permanently set second window ring 78. The three digit rings 70, 71, 79 rotate counterclockwise or clockwise 70 makes 1/12 revolution per hour, minute ring 71 makes one revolution per hour and second ring 79 makes one revolution per minute The numbers on rings 70, 71, 79 can be parallel or orthogonal to the circular arc Arabic numerals are suitable better, as shown in an example above.

A clock according to Fig. 2 according to a second embodiment of the invention, for example, by an electronic drive as in Fig. 13, see. US 3,712,046 dill, to be driven.

This watch needs (for example) two crowns to control the function of the dial rings 70, 71 and the window rings 72, 73. In addition, the clock can be equipped with an alarm function, as shown in Fig. 15. In the middle between the crowns 85, 87, a button 74 can be added at 3 o'clock position, which switches the alarm function on and off. The alarm time setting is set using the two adjustable rings 72, 73. As an orientation of the hour setting, there is a stronger mark 81 on the edge of the case every hour (1/12 turn). Alarm time can be appointment, appointment, alarm time etc. When the alarm time is turned on, an icon appears in the alarm window 96, which may be a small alarm bell, as in a conventional clock.

As an example, the clock of FIG. 15 indicates the alarm time 9:15. You have to imagine that the windows are the hands like in a conventional clock, in the inner ring "little pointer" The time is 3:45 minutes and 00 seconds The crown 87 has two positions Crown position 1 (Figures 8, 88) adjusts the minute ring 71, which allows the exact time (minutes) At the same time, when the crown is pulled out, the second hand 77 (version clock with second hand) goes to 12 o'clock position 83, ie to zero seconds.This function can be used to set the exact time.The crown position 2 (Fig. 8, 89) adjusts the hour differential ring 70, with which the clock time (hours) can be set exactly.With these functions, the movement continues to run normally in the "background".

For setting the displays in a clock according to a second embodiment of the invention, two crowns are used, as shown in FIG. 2 with the reference numerals 85, 87, wherein both crowns 85, 87 have two positions when pulled out (FIGS. 7, 90, 91). and (Figures 8, 88, 89). There are two ways to set the displays: 1. Time setting, 2. Window ring setting.

1. When setting the time with the crown (Fig. 20, 87), the minute-number ring 71 is set to position 1 (Fig. 20, 88), the gear Z 3 engages the gear Z 1, which meshes with the teeth ring Z 9 of the minute ring is connected. Z 1 is connected to the clockwork gear and thus moves the hour differential ring 70 via the gear Z 2 in the ratio 1:60, as in a conventional clock. With a snap mechanism on the axle, the hourly differential ring should only ever move at one full hour, so that only whole hour digits in the hour window become visible. For example, if the minute ring is set to 60 minutes from the minute window (the number 60 does not exist, but 00, ie after the number 59 should follow the digit "zero", 00 minutes for the next hour), the next hour must be in the hour window at- to be shown. At position 2 (FIGS. 20, 89), the hour-rate ferring 70 is set, and the toothed wheel Z 4 engages with the toothed wheel Z 2, which is connected to the toothed rim Z 10 of the hour-differential ring. On the axis of Z 4, it has only a spin mechanism of Z 4 rotates when the hour differential ring to a full hour (1/12 turn on the digit ring) to move. With this mechanism it is guaranteed that the hourly differential ring only adjusts by one full hour. In Fig. 18, the time setting is as in Fig. 20, except for the second differential ring goes to zero in this clock when the minute differential ring is adjusted.

2. When setting with the crown (Figures 20, 85), the minute window ring 72 is positioned at position 1 (Figures 20, 90) at any location but then fixed location, the gear Z 7 engages the gear Z 5 which is connected to the teeth circle Z 11 of the minute-fingering ring. Z 5 is in turn connected to the clockwork gear, so that when adjusting the minute window ring 72, the minute-number ring 71 moves synchronously with the 35 correspondingly indicated digit. (The time is not adjusted, only the position of the window rings 48-50). At position 2 (FIGS. 20, 91), the hour-window ring 73 is set, and the toothed wheel Z 8 engages the toothed wheel Z 6, which is connected to the toothed rim Z 12 of the timepiece ring. On the axis of Z 8 it has a snap mechanism, the Z 6 only rotates when the hour window ring to one hour (1/12 turn) to move. If one of these two rings 72, 73 is adjusted, as mentioned above, the respective number must run in the respective window, except a full minute or hour has just passed, ie the movement continues normally in the "background" adjusting the window rings as in Fig. 20, except that the crown 85 has three positions, position 1 second window ring, position 2 minute window ring and position 3 hour window ring. A timepiece according to a second embodiment of the invention can be constructed in various ways. Fig. 2 shows the clock in a version with Arabic numerals on the minute and hour digit ring, arranged parallel to the circular ring, with second hand.

The time is 3:45. Fig. 11 shows the clock in the version with Arabic numerals on the minute and hour number ring, arranged parallel to the circular ring, without a second hand. The time is 3:45 am, but the minute window ring and the hour window ring are set to a different position.

Fig. 12 shows the clock in the version with Arabic numerals on the minute and hour digit ring, arranged parallel to the circular ring, including second hand. The time is 3:45 and 39 seconds. Fig. 15 shows the clock in the version with Arabic numerals on the minute and hour digit ring, arranged parallel to the circular ring, with second hand and alarm function. The time is 3:45 minutes. Alarm is set to 9:15 minutes. Fig. 18 shows a clock with three digit rings and rectangular housing shape. Arranged with Arabic numerals on the second, minute and hour digit ring, orthogonal to the annulus. The time is 4 o'clock 29 minutes and 37 seconds.

In an advantageous embodiment, the display elements 72 and 73 are coupled together as usual hour and minute hands, so that setting this time via a crown rotation of the usual procedure corresponds, that is, a rotation of the minute hand 72 by 360 degrees leads to a further rotation of the hour hand 73 at 360/12 = 30 degrees.
