The invention relates to a watch having a watch face comprising an analog 12-hour display which displays a 24-hour day in an ambiguous manner using an hour hand and a minute hand, and an additional display which is used to determine the time indicated by the hour and minute hands and has two distinguishable symbols which are visible in said additional display separately from each other and change approximately every 12 hours. The invention is characterized in that the distinguishable symbols are configured as day and night symbols in such a way that they can be unambiguously interpreted as such by anyone and that the change-over from the night symbol to the day symbol occurs at 6 a.m. and the change-over from the day symbol to the night symbol at 6 p.m. either suddenly and precise to the second or over a period of time which can be observed dynamically so that there is never any doubt as to the time being shown.


Watch with a full-day dial

technical field

The invention relates to a timepiece having a dial, which consists of an analogue 12-hour display, which represents a 24-hour day using an hour hand and minute hand ambiguous, and has an auxiliary display that for the determination of the hourly and minute hands is displayed time and the two distinguishable symbols provides from each other in the auxiliary display separately visible and alternate in a time interval of about 12 hours.

State of the art

To illustrate the above-mentioned associated with analog Uhrzifferblätter problem that is not unique time determination are 1 to 5 known watch will be described using the figures.

Fig. 1a shows in the middle of the ambiguous half-day dial with the display on 6:00 or 18:00. Anyone who can read this normal dial is so used to it that he can read one of the two possible times by the position of the minute and hour hand. In the analog ambiguous halfway dial, which often contains numbers, but mostly just dots and lines, we read really only angle from and know what time it is. However, objectively can not be determined exactly the time you put the information exclusively for reasons that can be read by the clock. Without knowing whether it is in the evening or in the morning, the mere information of the pointer position does not allow eindeitige time assignment in the middle Uhrdarstellung.

Quite different, however, for example in one of the many analog 24-hour auxiliary dials. Left and right of part-time dial in figure 1 a time is 6:00 or 18 o'clock shown on a very frequent benützten dial, where the midnight is 24:00 at the zenith, at midday 12:00 at the point where we expect otherwise 6:00 or 18:00. How strange the presentation 6:00 18:00 is early or evening, this example clearly.

FIG. 1b. Again, in the middle of the ambiguous half-day dial in a typical angle that tells us clearly and quickly that it only 9:00 early or 21: 00 may be in the evening.

For both sides of the half-day dial a likewise very common variation of a 24-hour dial is shown in which, however, is represented in the zenith at noon 12:00 to 24:00 midnight on the ground. The inventor of this rare benützten dial may have felt that we expect the sun at 12:00 more overhead. Nevertheless, the representation of time is 9:00 or 12:00 just as confusing and without numbers can not be read.

Fig. 1c shows an analog clock with 3 analog time displays. At first glance, one would assume that all three dials 8:07 or 19:07 Show. Not even close. Only two of them, the main dial and the lower half of the known ambiguous halfway dials, while above the local time is displayed 16:07, but what one can only decipher when you look closely.

Fig. 1d shows a widely used 24-hour auxiliary display is shown with an hour hand. These auxiliary display is used only in conjunction with an ambiguous half-day dial, to make this clear. The hour hand is here at 21: 00th Fig. 1e is also widespread wristwatch, which represents 3 different times. All three times must be shown in this case, completely different, so elusive way. The main analog display in the ambiguous halfway dial displays at 8:07 and 20:07. In a 24-hour auxiliary display 1 this ambiguity is canceled because the hour hand of the auxiliary display shows at about 20:00. In order to understand this quickly because the pointer position to 20 o'clock is very foreign to us, are additionally 2 half day rings for pm and am, however am- pm- zones are us Europeans completely foreign. A 24-hour display 2 is similar to Fig. 1a is mounted in the upper part of the main dial. On the right side of the main dial 3, a second local time is provided in digital representation. By 3 different times to represent, are 4 different modes of representation benötigt.Ein quick grasp or perhaps comparing the times where it is now day or night, is, oddly enough, only in the numerical representation of that one but basically can not read fast.

Fig. 1f and Fig. 1g are timing charts in a rotating to the right dial, in which the bright side very clearly shows the day, the dark side of the night. , Characterized, however, that these dials to turn, the presentation time is 8:30 not automatically and instantaneously capture.

Fig. 1h illustrates a 24-hour circle that rotates once a day to the left to indicate a local time which is used with a rotatable bezel or as a fixed point in the wristwatch.

FIG. 1i shows represent a further variant, the day or night using a propeller-like hour hand. This wing moves once within 24 hours about its axis and shows a half-time scale with the bright wing times of the day, with the dark wing the night times.

Fig. 1k a half-day display 1 is similar to Fig. I, at which an hour hand rotates with 2 panels. On one hand, "N" stands for the night, on the other side "D" for day or time of day. Fig. 11 is a time chart with 2-time rings. On the outer ring part are the daylight hours 6:00 to 18:00, written early in the night hours 18:00 to 6:00 on the inner ring part. A 24-hour pointer, in which on the one hand a moon, on the other side of the sun are indicated, reveals to us what time it day or at night is.

Fig. 2a shows how it is used in heating a display. The sun and the moon are both shown on dark fields. A quick discrimination, which is the day or the night time is not given.

FIG. 2b shows a variant of the illustrated in Fig. 24-hour auxiliary display 1d. This foreign hour selection is somewhat easier detectable by the fact that the night time is 18:00 to 6:00 shown early in dark color, time of day in lighter colors.

However, Fig. 2c shows a 24-hour wrong angle display is also used in which strangely, the nighttime bright, the time of day is shown somewhat darker. Such a display unsettles the reader unfamiliar.

Fig. 2d shows a further 24-hour wrong angle auxiliary display a well-known watch. In the dark color is the pm time here, shown in light on the time so that it can no longer be closed on day or night.

Fig. 2e is bright, an auxiliary display of a wrist watch for the dark and for pm. Behind the circular right small window a 24-hour disk rotates, as with many other watches. In this illustration, it is about midnight. The little window is dark in the early morning hours and from 12:00 noon again getting light.

Fig. 2f is a 6 local time clock is to be sold as a unit for different international times. The local time ambiguous halfway dial is supplemented here by a am-pm auxiliary display (2f1). However, it is shown on the bright and dark pm in this display. Here, too, is therefore not easy to grasp a smooth transition and the time.

For a new Time Management Program still small analog time displays are not only the digital times represented to capture the time faster (see Fig. 2g). To remove the ambiguity of our normal dial, the on-time with light clock, pm time is shown with dark AM. Oddly enough, the night hours after midnight appear bright, the day after 12:00 hours dark!

Figure 2h. In the battle for customers simple and clear presentation of the store opening times plays a major role. Here is a successful attempt to take the ambiguous half-day dial any ambiguity. This type of representation has the advantage that it is very quickly detected over any other.

Fig. 2i shows only an overview at which points usually auxiliary windows are mounted in the dial:

1 which is under 2e. Discussed auxiliary window. The change takes place there from top to bottom. 2 is the day / night auxiliary windows of a 24 hour alarm. The change from day to night occurs smoothly and from right to left. 3 is an AM-PM window of a prior art wrist watch, which is represented by 2m. 4 is a day / night window of a watch, in which the transition from one period to the other also vertically, but from left to right. The uncertainty that make this window into the transitional period depends on their size. In no case, however, the display is clear, since the change is very slow sliding without that one can perceive a movement towards light or dark, so the time is not unique.

In Fig. 2k a wristwatch with two day / night auxiliary windows 1 and 2 is shown. The auxiliary window explains the main display. The second auxiliary window explaining a second hour hand 3, a second with the time can be displayed. This second time is to capture very good, because it is in a normal 12-hour-style ones shown,. However, a major disadvantage is the ambiguity during a relatively large period of time because the transition from day to night is also slidably here as in Fig. 21 is described.

Fig. 21 shows the change of the day / night window Fig. 2k. In Fig. 21, pictures 1 to 3, the darkening from bottom left to the top while in the images 4, 5 and 6, the darkening according to a right moving from bottom right to top.

Fig 2m. Figures 1 to 6 show the change of day and night window in a wristwatch in a window, which is mentioned in Fig 2i3.. The second time zone is displayed with this clock on a 24-hour scale on the edge of the dial with a white pointer. The change in the day / night window is done first with a point which comes from the lower right in the window, and then - see Fig 2I2 and 2I3 -. Followed by an area in right-hand rotation until the window after about 4 hours totally dark is.

Fig. 3a shows the sun and moon dial of a watch movement, in which the main dial has a larger window at 12:00. The ground is not bright as here in the drawing, but the sun and moon stand with their rays and stars on a blue sky, making the day / night boundary hard to see - and only in full sun or full moon uniqueness is given. These day / night indication is given either by the symbolism nor the color nor the exact replacement time.

FIG. 3b shows the dial of a watch, in which the half-day main dial is supplemented with a 24-hour display, the left shows, in contrast to all other 24-hour display midnight 24:00 (at 9 o'clock) - 6 : 00 early up (at 12:00) etc .. in this way the night time in the left half of the additional display, the day in the right half appears. In addition, the left is "Night" and right "Day", therefore the globally ever confused tra- Veller day and night. Fig. 3c is a wrist watch with an analog half-day local time indication (3c1) and an original 24-hour additional display shows (Fig. 3C2). Both displays are merging so that the togetherness is clear and the visibility is relatively good.

Fig. 3d is a further development of practical Fig. 3c. The analog local time (3d1) with a half-day dial is a day / night window supplemented (Fig. 3d2) through which a portion of the underlying rotating 24-hour disk is visible (see Fig. 3e).

Fig. 3e shows the change of the window from Fig. 3d2. but although the affiliation of the window is solved very well for half-day dial and even with a full day or full night, the display is very good, so is the doubt zone in the transitional period from light to dark or dark to light over a very long period of time, leading to an not given general, clear and unambiguous 24-hour display.

Fig. 3f shows one in which every second the right time can be read on the day 24-hour display because the change from a half day to the other not to slide, is per second as with all other systems, but. This is about the German patent "clock with dynamic time representation" (P 42 26 448).

Fig. 3F1 shows an analog clock with date in the upper half and a Terminschleppuhr in the lower half. In Fig. 3f2 but the Terminschleppuhr has a further characteristic, a ring, which can also be colored. This ring means that the time represented is located in the second half of the day. Thus was clear that the time to morning time in Fig 3f2. Refers in Fig. 3f1 on the evening. The ring which wraps around the clock, is effected by a mechanical device, as depicted at 3f3 and 3f4. Although this is compared with all other systems is by far the best solution, it is completely inadequate for a non-technical creation of a unique, natural 24-hour analog clock. Only the expert knows whether it is in the watch with a dark border around the am- pm or time, or perhaps the day or night (6:00 morning to 18:00 in the evening or 18:00 to 6:00) ,

In addition, the design is limited in essential points through this ring for strong edged analog dials in watches and table clocks are a popular artistic element.

This attempt to solve the problem and to present a clear, understandable and detectable at a glance time or local time, must be described as a failure.

In summary it can be said that the decades of attempts by many well-known international companies and individuals so far have not been successful to develop simple analogue time display in conjunction with the date for the presentation of appointments or to represent local example in the context of cities, for which an enormous by globalization demand.

All previous attempts, whether by the 24-hour dial, or the auxiliary displays contain no even remotely satisfactory solution. Neither the color nor the light or dark areas, nor the direction of movement, whether left or right, up or down, have any logical relationships with time. Added to this is that, except for the last example (Fig. 3f), the transitions from one half of the day to another are always displayed slide to act statically, a movement can not be seen and the time display can not be exactly recognized for hours can be. Thus, day or night icons and even pictures of the moon or sun have yielded no solution to the problem.

Using the above unsatisfactory dissolved distinctive ways whether it is day or night it is, but it is still to some extent possible to enter date prone dates as target times in a day. you want to set more distant times, for example, are 5 or 20 hours from the present time in analog desk or wrist watches that are with the current watches a problem because they are either very slow or very confusing steer towards such a time.

There are basically two systems. The first time the needle on the analog dial go minute by minute and hour by hour on the goal to show this time or go after the appointment was shown back to the present time. This process takes at the usual clock 15 to 30 seconds. A quick display of an appointment is not possible with this, also the real time can be displayed within a full day 24 hours only with the help of a second 24-hour auxiliary pointer or the like.

A faster method that is increasingly being used, is that the minute and hour hands are kept separate and that on the respective shortest way to display the target time. How confusing this is, is easy to imagine, because often the hands rotate in reverse when a time is displayed that lies ahead. It is also not possible to follow this process internally, because the cursor movement is completely detached from the removal of the to be driven target time. In order to create these problems corrective and represent great leaps in time to known important early days as the beginning of the afternoon, evening, the beginning of the next day, the next week or the next month, be related to the new, natural 24-hour dial performed here.

Summary of the Invention

The invention is based on the object to create a new 24-hour dial, which throughout the day a unique time display allows based on our present ambiguous half-day dial, which by anyone around the world, captured clearly and quickly between young and old in any cultural environment can be. This new Dial will not only allow the display of world times in connection with cities such as at airports, stock exchanges, banks, travel agencies, reception halls, table and watches, but just for the presentation of appointment times relating to date and for the general time display during the entire day at store opening times, computer time representations, television stations, allow. This dial should be designed so that it can be combined versatile, such as appointment times with world times Abiaufzeiten etc., times, all the presented with the same dial and therefore can be compared quickly. Moreover, the clock is to give the user the ability to easily using the unique distinction between day and night and visually easy to understand set of lying in the future target time points.

The object underlying the invention is indicated in claim 1 and 13. FIG. The inventive concept advantageous forming features are the subject of the dependent claims.

According to the invention is a timepiece having a dial with an analogue 12-hour display, which represents a 24-hour day using an hour hand and minute hand ambiguous, an auxiliary display that is used to determine the direction indicated by the hour and minute hands time and the two having distinguishable symbols that are separated from each other in the auxiliary reading visible and alternate in a time interval of about 12 hours, formed such that the distinguishable symbols are designed as day and night symbol such that it from anyone are clearly interpertierbar, and that the change from night icon to the tag icon at 6am and the change from the tag icon on the night symbol at 18 o'clock, either abruptly and accurate to the second, or takes place in a dynamic miterlebbaren period so that any time there is clarity on the time of day. Such miterlebbare periods are typically a few seconds, a maximum of 1 minute.

Therefore, a watch according to the invention preferably has the following characteristics: The time display has as today's half-day display the same hands and the same numerals hour leaf.

There are shown two half times of the day, but not 12 hours and 12 hours pm but the natural day and night from 6:00 morning to 18:00 in the evening and 18:00 in the evening until early 6:00. There are the typical day and night symbols Sun and Moon used. To underline day by a light surface with the sun and a dark area is used with moon. Thus, day and night is instantly recognizable in two ways and for everyone, and by the color scheme - has the dark or bright area a great distance effect - even with any non-unique symbol recognition of the distance.

The time accuracy during the entire 24 hours is ensured that the day or night numerals surrounded the exact second, so by spring sun at 6:00 early in the beginning of the day - is presented at 18:00 by the leaping moon beginning of the night.

, The day or night symbol is attached to a striking position in the dial, so that the readability of the time display is virtually not limited, and that, moreover, an extensive possibility of combination with other timing charts in the same dial can be performed.

Further, the display and the setting of target times enterable by typical movements of pointers according to the invention is carried out so that each of the typical hand guiding the target time point is already characterizable. A user can go with internally and on reaching the target point in time, the event of the arrival of the pointer position it is indicating precise, either through a typical hand position, the change in the day / night symbol or one date. To enter the target times are target time keys as example. From WO 93/03428 emerge provided. The disclosure of this document is expressly noted at this point and reference. One can - always starting from the present time - by single or repeated operation of an input means heading directly at peak times. The idea according to the invention for this is described with particular reference to the figures.

Further, it is of particular advantage when carried out at a starting of a point in the future appointment time points are also affected date, the date change and the respective setting of the sun / moon symbols quickly and / or erratic. The hour and minute hands move on the shortest route from the currently displayed time, to the respective lying in the future appointment time. For example. at a current time of 12:30 and a future appointment time of 9:45, to be displayed as quickly as possible on the clock, the minute hand moves clockwise from the 6 °° °° to 9 and the hour hand position of the "After 12 °° position" into the "After 9 °° position" counterclockwise. In this way, the clock hands can assume the positions of the new appointment time in a short period of time.

Brief Description of Drawings

The invention is described below, without limiting the general inventive idea with reference to embodiments with reference to the drawings. Show it:

Fig. 1 - 3 Known Uhrzifferblätter

Fig. 4 - 5 Uhrzifferblätter with inventive additional display 6 ae representation of a fast and reproducible setting of target points in time and Figure 7a-c miterlebbarer dynamically switch between day and Nachtsysmbol...

Representation of exemplary embodiments and industrial applicability

Fig. 4a shows three typical world times in New York, Paris and Tokyo, which can be easily read by anyone. A characteristic of the Sun and the Moon in the entire dial is that the intersection of the boundary of the sun and moon symbols normally passes exactly through the point on the dial, on the other of the first and second hour is displayed. Thus, the minutes 6 to 9, but this is not necessary in all models shown here could also be applied in case of need with appropriate Ausildung the pointer and the sun and moon symbol on the edge of the day or night symbol.

FIG. 4b shows a clock with date-time input in the base in accordance with patent and the entered date is displayed on an additional display in the main dial - 10:13 am here. The watch is also equipped with two world times, their reading everyone's understandable. Watches with this type the great demand can be satisfied by world time and time clocks.

Fig. 4c shows an astronaut reminder clock. In the main dial the night symbol moon on a dark surface to show that the main display shows early 21:00 and not 9:00 except the analog appointment display 10:13 in the morning.

FIG. 5a is again a Astronautenuhr, characterized by great night icon on the main dial. In the same analog representation are two more time displays that can be used for appointment times, local or other purposes and must be recognized as swift. A fourth display enables the display of additional data - even other times, even if only in a digital manner.

Fig. 5b is the combination of a chronograph with an appointment time.

Fig. 5c is a world time and reminder clock. On the one natural 24-hour display, a date can be dagestellt in connection with the date. In the second natural 24-hour dial a universal time, for example, in conjunction with an additional pointer may be displayed, pointing to a city on the edge of the dial.

In other ads for watches, screen images as well as images of shop opening times, TV times, etc. as these of the few examples listed here are analogous evident is waived. FIG. 6 shows four representations, as the jumps on the time of day (12:00, 18:00, 0:00, 6:00), to tomorrow, Monday or the beginning of a month are performed. It is this accomplished with 4 elements. Once with segregated pointers with the symbols sun and moon, day and night, as well as the date display.

Fig. 6.a. shows the input elements for the starting of a target times starting from the present time. The round button on which the sun for 12:00 noon, the moon for 18:00 is at night, allowing the start of the beginning of the day peak hours midday, evening, night and morning. The overlying triangular button with the abbreviations "To" for tomorrow (Tomorrow), "Mo" for Monday and "M" for month allows single or multiple input the target times morning (0:00), the next Monday (0:00) or the beginning of next month (0:00). If you want to, for example, come on Tuesday next week 6:00 am, one would the Monday button (Monday 12:00), then the Tomorrow button (Tuesday 00:00) then the round time of day button (jump from midnight to 6:00 early). in order to follow this process internally and yet very rapidly perform the time input, the typical pointer movements in Fig. 6b are explained to 6e.

In FIG. 6.b. starts from the time (1) 8:10. The first target time is 12:00 (3). Instead of rotating hour after hour at 12:00, the minute hand moves only toward 12 o'clock, while the hour hand starts at the same target (2). Both hands are simultaneously at 12:00. The next day Time 18:00 h is also achieved in only a forward rotation by both pointers move towards isolated on their respective target (4). During the last approach from 17:59 to 18:00 the day / night indicator of solar jumping on the moon and in the same way one might jump in understandable and comprehensible manner internally to midnight 00:00. This third jump to 0:00 but would make no sense, because he is overcome with just one key press and the "Tomorrow-Jump" or "Next-Day Jump" as follows. Fig. 6.c. Output is, as in all following examples, the time 8:10 (1) on (W = Wednesday) is 20 The objective, morning, Thursday 21 (T = 21 Thursday), 0.00 (5). Again both hands to move separately, wherein said first rotation is performed during the day and the hour hand at an angle of 45 ° on the south border 12:00 18:00 direction is pushed (2), when crossing the evening time limit (3) 18:00 bounces the day display sun on the moon. In this 45 ° angle, which impresses itself to the user as a jump to the next well, the first hour hand reaches 12:00 (4) so ​​that this angle of 45 ° stands for the fraction of a second as a vertical angle memorable before the next day. Grab the big hand to 0:00, also skips the day display from Wednesday 20 to Thursday 21 (T 21). A jump to the next day from 0:00 could be similarly represented graphically as here in two turns at a 45 ° angle, which at 6:00 the sun and again at 18:00 the moon appears.

Fig. 6.d. shows a jump from Wednesday, 20 (1), on Monday, 25 (5). The charac- acteristic for a jump on Monday is the right angle at which the hour and minute hands move toward the goal. During this movement, the date display changes continuously from Wednesday 20 to Monday 25, with the date of Sunday only changes on Monday, when the minute hand has closed the 45 ° angle to 0 (5). With a jump on the following Monday, the hour hand would first leap forward and represents the 45 ° angle to the minute hand, after which the rotation could start towards the finish.

Fig. 6.e. illustrates the jump to the beginning of the next month, wherein the characteristic of the angle of 180 ° for the month jump. Pressing the Month button several times, the hands always rotate in the same 180-degree position as a propeller and the date of the target month appears, so you have a clear orientation for jumping with an analog display. b.-e. with Fig. 6 forward movements are displayed on a target in a manner analogous to that can accompany inwardly. the display automatically returns to the present time or a very obvious appointment, then a backward movement of the pointer and the date format in a similar manner as described here, the forward movement.

The embodiment of FIG. 7 is based on strongly to what we see in nature.

the all-day dial refers to a date representation that can be entered very quickly, the question is not whether you can evenings watch the changing of the sun and moon at 6 am and 18 am, for the time display for appointments remains motionless.

In contrast, however, the all-day display is used with a clock as the main display, and the transition from day to night and night to day into an experience. Moreover, it would in some cases more convenient to delay this process somewhat if the recordable in action at a distance, the second hand can not be seen, but rather whether the sun is small, so sunset or vice versa.

This embodiment is particularly cause a strong emotional experience and it is night very clearly by the movement of the stars and rising of the moon show. For countries where thirty percent of younger people practically can not read the ambiguous half-day dial, there is thus the possibility of a completely new approach to analog "Twelve - hour - clock" to get if it is understood that the day of twelve night - and twelve daytime hours there.

Fig. 7a shows a wristwatch with dial 1 and an opening 2 through which a moon is seen, which is part of a sun-moon disk 4. By slowly turning the wheel the switch from night to day or from day can be witnessed at night. Fig. 7b shows the change of the sun on moon in sliding transition by sunset and sunrise is simulated.

FIG. 7b is a dial 1 with an opening 2, the sun 3 shown can be seen by the on a lower level. Between the dial 1 and the underlying layer 2 on which the sun is displayed, a star / moon - moving eccentric disc 4, which can be rotated in a counterclockwise direction at sunset about the main axis 5, so that the disc at a slow left-hand rotation the sun slowly darkened left upward obliquely from below and the beginning of a sunset is displayed. 6 At 7 some stars already appear. Phase 8 is how to put on the star / moon - can see disc aware an extended period because the movement of the stars is particularly nice to look again, to another, but also because this specific constellations can be shown, depending on the clock from the manufacturer or watchmaker with the desired zodiac signs or more signs of the zodiac could be produced, which would be interesting for the sale. The phase 9 passes the final stage 10 a with moon.

The sunrise is effected by rotating the disc in a clockwise direction.

Fig. 7c shows a slightly different solution of the same idea, namely to allow the sunset and sunrise appear natural as possible. While the sun is rather obscured from left bottom Fig. 7b is shown a somewhat simpler, less dynamic but more realistic in the course of the horizon change from sunrise and sunset in Fig. 7c. In the main dial 1 is also as in Fig. 7b, an opening 2, which can see the sun illustrated therein on the underlying Level 3. A moon disc 4 can be moved about the axis 5, wherein a cutout 6 on this plate allows the through projection of the axes of the pointer of the main clock face. This moon disc is located between the main dial 1 and the underlying layer 3 on which the sun is displayed. This moon disc can now be pivoted by a clockwise rotation about the axis 5 of the drawn here the 7-position to position. 8 Whereby the sun obscured relatively accurately from bottom to top, as indicated in the positions 9 to 13. The advantage compared to the solution 7b is that this transition takes place, of course, although less dramatic but relatively waagrechteren by the horizon.

All solutions are "jumping the moon" or "spring sun" the advantage that the transition period of several seconds can be drawn without doubt about whether it will be day or night over the.
