Abstract

An electric timepiece having a square dial with corners at the twelve, three, six and nine o'clock positions has a first array of twelve light sources at one to twelve o'clock positions, a second array of four light sources which are inwardly adjacent the light sources of the first array at the twelve, three, six and nine o'clock positions, and a centrally located light source. The color and/or intensity of radiation issuing from the centrally located light source changes at midnight and at noon, and all of the remaining light sources are used to indicate minutes. The light sources of the second array indicate single-minute periods, and the light sources of the first array indicate five-minute periods. In addition, the light sources of the first array are used to indicate hours in colors or hues other than those used to denote five-minute periods.

Description

Die Erfindung betrifft eine elektrische Uhr, aus einer mit Leuchtelementen versehenen Anzeigefläche und einem elektronischen Gerät zur Steuerung dieser Leuchtelemente.The invention relates to an electric clock, comprising a display surface provided with lighting elements and an electronic device for controlling these lighting elements.

Herkömmliche elektrische Uhren arbeiten entweder mit Zeigern oder mit Ziffernblättern (Analoganzeige) oder mit Hilfe wechselnder Ziffern (Digitalanzeige).Conventional electric clocks work either with hands or with dials (analog display) or with the help of changing numbers (digital display).

Bisherige elektrische Uhren, welche mit Leuchtelementenanzeige arbeiten (DE-Gebrauchsmuster G 84 34 084.3 und G 85 12 790.6), übernehmen das Grundprinzip einer Analoguhr. Sie benötigen 12 + 60 Leuchtelemente zur Anzeige von Stunden und Minuten (Anordnung in Kreisform); dabei erlauben sie keine Unterscheidung zwischen den Zeiträumen 0 - 12 und 13 - 24 Uhr.Previous electrical clocks that work with light element display (DE utility model G 84 34 084.3 and G 85 12 790.6) adopt the basic principle of an analog clock. You need 12 + 60 light elements to display hours and minutes (arranged in a circle); they do not allow a distinction to be made between the periods 0:00 to 12:00 and 1:00 to 12:00 midnight.

Der Erfindung liegt die Aufgabe zugrunde, eine elektrische Uhr der gleichen Art zu schaffen, bei der weniger als 12 + 60 Leuchtelemente zur Anzeige der aktuellen Zeit in Stunden und Minuten erforderlich sind und zusätzlich zwischen den Zeiträumen 0 - 12 und 13 - 24 Uhr unterschieden werden kann.The invention has for its object to provide an electric clock of the same type, in which fewer than 12 + 60 lighting elements are required to display the current time in hours and minutes, and in addition a distinction is made between the periods 0-12 and 13-24 can.

Diese Aufgabe wird bei einer eingangs näher bezeichneten Uhr dadurch gelöst, daß die der Anzeige dienende Fläche als auf der Spitze stehendes quadratisches Feld ausgebildet und mit 16 Leuchtelementen versehen ist, wobei auf dem äußeren Teil zwölf Leuchtelemente sowie auf dem inneren Teil vier Leuchtelemente jeweils symmetrisch angeordnet sind.This object is achieved in a clock specified in the introduction in that the surface serving for the display is designed as a square field standing on top and is provided with 16 lighting elements, with twelve lighting elements on the outer part and four light elements on the inner part each being arranged symmetrically are.

Nach einer weiteren Ausbildung der Erfindung ist vorgesehen, daß in der Mitte des quadratischen Felds ein zusätliches Leuchtelement angeordnet ist.According to a further embodiment of the invention it is provided that an additional lighting element is arranged in the middle of the square field.

Eine andere Ausbildung der Erfindung besteht darin, daß die zwölf Leuchtelemente, die vier Leuchtelemente sowie das zusätliche Leuchtelement in Form, Farbe und Größe voneinander verschieden sein können.Another embodiment of the invention is that the twelve lighting elements, the four lighting elements and the additional lighting element can be different in shape, color and size.

Erfindungsgemäß ist vorgesehen, daß als Leuchtelemente mehrfarbig ansteuerbare Dioden verwendet werden.It is provided according to the invention that diodes which can be controlled in multiple colors are used as lighting elements.

Das elektrische Steuergerät ist zweckmäßigerweise so ausgebildet, daß als Steuergerät für die Leuchtelemente drei hintereinander geschaltete Zähler mit nachgeschalteten Dekodern vorgesehen sind, daß die Zähler über einen Frequenzteiler mit einem quarzstabilisierten Oszillator verbunden sind und daß die Anzeige für Vor-/Nachmittag von dem Stundenzähler über eine Flip-Flop-Schaltung gesteuert wird.The electrical control unit is expediently designed such that three consecutive counters with downstream decoders are provided as control units for the lighting elements, that the counters are connected via a frequency divider to a quartz-stabilized oscillator and that the display for morning / afternoon from the hour counter via a Flip-flop circuit is controlled.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß mit einem geringen Aufwand an Anzeigemitteln eindeutig die Zeit nach Stunden und Minuten sowie die Unterscheidung nach Vor- bzw. Nachmittag abgelesen werden kann.The advantages achieved with the invention consist in particular in that the time after hours and minutes and the distinction after morning and afternoon can be read clearly with a small expenditure of display means.

Die Erfindung wird anhand der Zeichnungen näher erläutert.The invention is explained in more detail with reference to the drawings.

  • Fig. 1, the display panel of the new electric clock and
  • Fig. 2 shows the block diagram of the associated electrical control unit.

Die Uhrzeit wird gemäß Fig. 1 durch Verwendung eines auf der Spitze stehenden quadratischen Felds 1 als Anzeigefläche und Anordnung von 12 symmetrisch verteilten Leuchtelementen 4 im äußeren Teil 2 und vier symmetrisch verteilten Leuchtelementen 5 im inneren Teil 3 durch Aufleuchten eines oder zweier Leuchtelemente 4 des äußeren Teils 2 und gegebenenfalls von einem bis vier Leuchtelemente 5 des inneren Teils 3 angezeigt, wobei die Leuchtelemente 4, 5 je nach Stunden- und Minutenanzeige in unterschiedlicher Farbe aufleuchten (z.B. grün für die Stunden und rot für die Minuten).The time is shown in FIG. 1 by using a square field 1 standing on the top as a display area and arrangement of 12 symmetrically distributed lighting elements 4 in the outer part 2 and four symmetrically distributed lighting elements 5 in the inner part 3 by lighting up one or two lighting elements 4 of the outer Part 2 and optionally one to four light elements 5 of the inner part 3 are displayed, the light elements 4, 5 lighting up in different colors depending on the hour and minute display (for example green for the hours and red for the minutes).

Die Stundenanzeige erfolgt durch Aufleuchten einer der im äußeren Teil 2 angeordneten Leuchtelemente, wobei diese wie die Stundenziffern herkömmlicher Uhren angebracht sind und dem oberen Leuchtelement die Uhrzeit 12 bzw. 24 und dem unteren Leuchtelement die Uhrzeit 6 bzw. 18, sowie den dazwischen liegenden Leuchtelementen die ihnen entsprechende Uhzreit zugeordnet ist.The hour is displayed by lighting up one of the lighting elements arranged in the outer part 2, which are attached like the hour numbers of conventional clocks and the upper lighting element the time 12 or 24 and the lower lighting element the time 6 or 18, and the lighting elements in between which are assigned the corresponding time.

Die Minutenanzeige erfolgt einmal durch Aufleuchten eines der gleichen zwölf Leuchtelemente 4 im Uhrzeigersinn für alle Fünf-Minuten und durch die im inneren Teil 3 liegenden vier Leuchtelemente 5 für die jeweils vier folgenden Minuten, in einer von der Stundenanzeige verschiedenen Farbe.The minute is displayed once by lighting up one of the same twelve lighting elements 4 in a clockwise direction for all five minutes and by the four lighting elements 5 in the inner part 3 for the four subsequent minutes each, in a color different from the hour display.

Das sich stündlich einmal ergebende Problem, zur gleichen Zeit mit dem gleichen Leuchtelement sowohl eine Stunden- als auch eine (Fünf-) Minutenanzeige auszudrücken (vergleichbar der Situation des Überlagerns der Zeiger bei einer Analoguhr), ist dadurch gelöst, daß für diesen Zeitraum das betreffende Leuchtelement doppelt angesteuert wird und in einer dritten, von den beiden anderen Farben unterscheidbaren Farbe aufleuchtet.The problem that arises once an hour, of expressing both an hour and a (five) minute display at the same time with the same light element (comparable to the situation where the hands are superimposed on an analogue clock), is solved by the fact that for this period the relevant one Light element is controlled twice and lights up in a third color that can be distinguished from the other two colors.

In der Mitte des quadratischen Felds 1 ist ein zusätzliches Leuchtelement 6 angeordnet, welches beispielsweise während der zweiten Tageshälfte (13 bis 24 Uhr) ständig erleuchtet bleibt, um so auf einen Blick die beiden Tageshälften unterscheiden zu können.In the middle of the square field 1 there is an additional lighting element 6 which, for example, remains illuminated during the second half of the day (1:00 p.m. to midnight) so that the two halves of the day can be distinguished at a glance.

In Fig. 1 sind besonders (strahlenförmig) gekenneichnet vier Leuchtelemente 4, 5, 6, welche durch ihr Aufleuchten die Uhrzeit 13 Uhr und 11 Minuten angeben, wobei z.B. die Stunden in grüner und die Minuten in roter, sowie die weite Tageshälfte in roter Farbe angezeigt werden können.In Fig. 1, four (4), 6, 6 are particularly marked (radiating), which, when illuminated, indicate the time 1:00 p.m. and 11 minutes, for example the hours in green and the minutes in red, and the broad half of the day in red can be displayed.

Aus Fig. 2 ist das Blockschaltbild des elektrischen Steuergeräts für die Leuchtelemente 4, 5, 6 ersichtlich. Es ist ein quarstabilisierter Oszillator 7 vorgesehen, der z.B. eine Frequenz von 32 kHz erzeugt. Mit 8 ist ein Frequenzteiler bezeichnet, mit dessen Hilfe die Oszillatorfrequenz auf 1 Hz herunter geteilt wird, um damit einen ersten Zähler 9 anzusteuern. Dieser Zähler 9 steuert alle 60 Sekunden über einen Dekoder 10 die Leuchtelemente 5 für die Minutenanzeige 1 bis 4.2 shows the block diagram of the electrical control device for the lighting elements 4, 5, 6. A quartz stabilized oscillator 7 is provided, which e.g. generates a frequency of 32 kHz. 8 denotes a frequency divider, by means of which the oscillator frequency is divided down to 1 Hz in order to control a first counter 9. This counter 9 controls the lighting elements 5 for the minute display 1 to 4 every 60 seconds via a decoder 10.

Ist der 4-Minutenzähler 9 (mit Impulsen) voll gelaufen, so gibt er einen Impuls an den Zähler 11 für die 5-Minuten-Intervalle, die mit den Leuchtelementen 4 angezeigt werden. Der Zähler 11 ist über den Dekoder 12 mit den Leuchtelementen 4 verbunden.If the 4-minute counter 9 (with pulses) has run full, it gives a pulse to the counter 11 for the 5-minute intervals which are indicated by the lighting elements 4. The counter 11 is connected to the lighting elements 4 via the decoder 12.

Der Stundenzähler 13 erhalt Impulse von dem Zähler 11 und steuert nach Ablauf jeder Stunde über den Dekoder 14 ebenfalls die Leuchtelemente 4 an.The hour counter 13 receives pulses from the counter 11 and also controls the lighting elements 4 via the decoder 14 after each hour.

Die Leuchtelemente 4 können so ausgebildet sein, daß sie, als 5-Minutenanzeige angesteuert, grün aufleuchten. Werden die Leuchtelemente 4 dagegen als Stundenanzeige angesteuert, so leuchten sie z.B. rot auf. Wenn einmal pro Stunde die 5-Minutenanzeige und die Stundenanzeige mit dem gleichen Leuchtelement 4 erfolgen, so leuchtet das Leuchtelement 4 in einer von grün und rot verschiedenen Farbe.The lighting elements 4 can be designed such that they light up green when activated as a 5-minute display. If, on the other hand, the lighting elements 4 are activated as an hour display, they light up e.g. red on. If the 5-minute display and the hour display occur once per hour with the same lighting element 4, the lighting element 4 lights up in a color different from green and red.

Nach Ablauf von 12 Stunden gibt der Stundenzähler 13 einen Impuls an die Flip-Flop-Schaltung 15, die das Leuchtelement 6 je nach Tageszeit aufleuchten oder erlöschen läßt. Auf diese Weise kann auf der Uhr jederzeit abgelesen werden, ob die Zeit für Vor- oder Nachmittag angezeigt wird.After 12 hours have passed, the hour counter 13 gives a pulse to the flip-flop circuit 15 which, depending on the time of day, causes the lighting element 6 to light up or go out. This way, on the watch read at any time whether the time for morning or afternoon is displayed.

Mit 16 ist ein Netzteil bezeichnet, das die Stromversorgung für alle Elemente des elektrischen Steuergeräts sicherstellt.With 16 a power supply is designated, which ensures the power supply for all elements of the electrical control unit.

Die elektrische Uhr nach der Erfindung kann für alle Uhren-Typen verwendet werden, so beispielsweise als Stand-, Tisch-, Wand- oder am Arm zu tragende Uhr.The electric clock according to the invention can be used for all types of clocks, for example as a standing, table, wall or arm-worn clock.
