Abstract

The time display has a substrate having a display surface, medium for visual highlighting of discrete points. The scales are arranged such that the starting point for each display of the hour for display corresponds to a closed analogue circulating hour arrangement and the finishing point is arranged distinctly separate from the temporally directly succeeding hour position. The display of the change in hour occurs with a jump and the scales form a common intersection, through which each scale runs or the scales actually or in the imaginary extension thereof do not form a common intersection.

Description

The invention relates to a time indicator.

The analog representation of the time is usually carried out by means of the known circular analog or also referred to as closed-analog or linear-analog display types.

In the circular-analog representation of the time usually by means of the known pointer display the variable distances of time in hour, minute and possibly second by separate hands circumferentially clockwise on one, the variable distance associated circularly closed scale by the immediate reference of the distance traveled by the pointer displayed to the reference point of the scale. The total value of the time is read by adding the displayed individual values.

Usually, the scales of the variable distances to be displayed are arranged in a display area with a common center and the reference points are set to the "12 o'clock" or 24 o'clock "position of the hourly value Hourly, the scale of the hourly value is subdivided into 12 subsections, whereby the "five-steps" (5-10-15-etc.) of the scales of minute and second subdivided into 60 sections each have identical geometric positions with the full hours of the 12- This system of overlapping scales is so well-known to the observer that, for aesthetic reasons, visible scaling is often dispensed with and the mere position of the pointers with respect to their known reference points at the "12 o'clock position" provides a sufficiently accurate estimate of the displayed one Time in hours, minutes and possibly seconds, therefore also circul ar-analog displays are known that use other, non-numeric symbols instead of indicating numeric characters on the dial.

Also known is the use of multiple display areas or display means in a display area, for example, simultaneous display of the time of day different time zones or the time of day and additionally the moon phases, a stopped time, the calendar day, etc.

The hour hand in the conventional 12-hour clock performs a continuous rotation of 30 degrees in the course of one hour and 15 degrees in the 24-hour clock, which displays not only the current hour but also the minutes within that 15 or 30 degrees. Pointer watches are known which indicate the hour and minute alone with the continuously rotating hour hand. It is also known that the hour hand in multi-hand clocks the rotational movement to the next following hour position takes place suddenly at the time of the hour change and relocate from Kreissegmentskalenanordnungen pointers as a function of time leaps and bounds to the reference point of the scale. In circularly circulating multi-hand watches, the minute hand makes a rotation of 360 degrees per hour and the second hand of 360 degrees per minute.

A number of inventions, such as the publication CH534379 . US2006104160 such as US4939708 . GB2376089 . US6683821 . DE3731872 have set themselves the task of changing the appearance of the above "pointer clock" by using instead of one or more pointer elements each have a helical, optically contrasting disc pair with common center and provided with a radial slot use. Starting from the 12 o'clock position as the respective scale reference point, the first rear disk shifts completely in rotation in the clockwise direction as a function of time in front of the first overlapping disk through its radial slot, whereby the visible sector segment formed by the exit point at the 12 o'clock position and the visible radial slit of the displacing forward disc cumulatively and thus, compared to the known clock with increased intuitive estimation of the displayed time "at a glance" indicates the course of each displayed variable value. The proposal is for 12 hour clocks by means of alternating hourly slices between day and night, alternating at 12-hour intervals Distinguish night hours, for example, by the lighter disc 12 "day hours" and the darker the 12 "night hours" 24 hours a day, or the 12 hour rhythm each fixed at the 6 o'clock or 8 o'clock position to index, thereby the Reflect the light course of a 24-hour day almost realistically.

From the publication FR368617 For example, the hour and minute display are known by an hour hand, which is 30 degrees (12-hour display) or 15 degrees (24-hour display) per hour, and a minute scale with subdivisions of 390 degrees (12-hour display ) or 375 degrees (24-hour display) per hour. The hour hand indicates the hour at the hour positions of the circulating "hand watch" and the minute value by superimposing the numerical value of the minute scale corresponding directly to the hour position. This display does not allow the waiver of a visible scale division with numerical indication, which is often desired for aesthetic reasons.

From the publication EP0209335 For example, a time display is known in which the minutes are indicated by a pointer in direct relation to the current hour by "walking" the reference point of the minute scale with the rotation of the hour hand of 30 degrees in one hour, and the minute hand rotating by 390 degrees in one hour takes place. The reading of the current minute value is made more difficult by the reference point, which changes continuously in its geometric position, in that the position of the hour hand must first be determined precisely, in order then to be able to determine its displayed value on the basis of the relative position of the minute hand. Since the appearance of this display is equal to that of the conventional "two-hand watch", it has a considerable potential for confusion with it and the time indicated. The invention therefore provides to visibly display the subdivision of the "wandering" minute scale so as to be able to read the given numerical value or, at the respective position of the minute hand, by means of the numerical values specified in the immediate vicinity on the "wandering" minute scale. The display thus does not allow an intuitive reading of the time "at a glance" and also requires three, depending on the time shifting display elements for displaying two variable values.

From the publication DE2044355 as well as for example DE3632785 . EP199808 For example, there are known displays using minute and hour rings for time display in accordance with the above-described principle of the minute display directly corresponding to the minute display, in which the minute-representing ring is eccentric to the "hour ring" and the current value of the time at which, by the rotational movement of the "minute ring" resulting Adjazenzpunkt is read by means of mapped numerical values. Similarly, the hour ring by means of eccentric storage and rotational movement cause the Adjazenzpunkt with the minute ring. Disadvantage of this principle is the dependence of the size ratio of each other eccentrically mounted rings, as with similar sized rings, the precise determination of Adjazenzpunktes and thus the time displayed is difficult, or at significantly different sizes of the smaller ring has a smaller scale and thus the time this Variable value one, in comparison, has significantly lower reading accuracy.

The publication WO0031594 develops this principle further so that a much smaller minute ring forms a clearer adjacency point with the hour ring and thus allows the more precise determination of the hour and indicates the minutes by means of the adjacency point of the minute ring with an additional disc rotating in the minute ring. As a result, the invention can dispense with the specification of visible scale divisions and numbers and allows a just as intuitively readable as clear time display. Due to the smaller display screen, however, the minutes display is significantly less precise than, for example, in the case of the conventional watch with superimposed, equally large hour and minute scales. In addition, this display principle requires three, depending on the time shifting display means for displaying two variable values.

The GB 1 429 688 A shows in the expression of FIG. 2 a wristwatch whose time display graphically indicates the hours and minutes according to the known circular 12 hour analogue display beginning at the 12 o'clock position in two separate scales such that the hours are cumulatively referred to as "fruits" of a tree at the known hour positions are displayed and the minutes at the hour positions in 5-minute increments by means of 5 inward "leaves" are also displayed cumulatively.

It is well known that the described time display principles can be realized by means of mechanically moving or electro-optical highlighting means.

The advantage of the predominantly applied "hand watch" with overlapping scales of equal size is that each scale fully utilizes the entire available space of the display and thus allows the greatest possible detail within the given display frame. A disadvantage is that the scales do not correspond directly with each other, whereby each individual pointer positions have to be thoughtfully projected and read into their respective geometric scale and the individual results determined in this way must be added to form an overall result. This explains why adolescents learn the "clock" at a relatively late stage of development, since the "intuitive" reading of the clock is based on detailed knowledge and considerable reading exercise. In addition, this watch has the disadvantage that on the one hand, the size of the entire display area, and thus the individual scales, determines the display accuracy of the displayed time values, such as hour and minute, and therefore a large display area is desirable, but this with the, at a glance "Detecting the pointer positions at geometric distance to each other is difficult, or at pointer positions in geometric proximity to each other carries the risk of confusion of the represented variable values, the more the smaller the display surface is formed.

Although the described group of cumulative displays by means of turntables offer a changed appearance, they do not solve the described reading disadvantages of the display of conventional "hand clocks" by the use of separate display means for the respective time intervals such as hour and minute. In addition, their use of the 12 o'clock position as the starting point for the cumulatively displaying the time segment of the circle segment already indicates the known scale arrangement and thus its time-indicating function. This effect increases the more variable distances by means of additional pairs of discs are used, since in addition to the visible common starting point at the 12 o'clock position also the time-indicating endpoints of the circle segment sectors are identical to the pointer positions of the conventional "hand watch" and therefore reveal the time-indicating function immediately.

The time display by means of adjacency points formed from eccentrically mounted disc arrangement for the respective time intervals such as hour and minute allows appearances that do not close due to the viewing habits directly on their time-indicating function and, depending on the specific form, increase the intuitive detectability of the time displayed, this However, only with reduced display accuracy or using a larger number depending on the time displaced display means are displayed as variable values.

In the linear-analog representation, the possible result values of the time intervals to be displayed, for example the hour, minute and second, in, for each value of time (hour, minute, second) to be displayed become separate linear scales with spatially separated start and end points shown. It is known from the published patent application DE 29504124 for displaying the 12 hours of a half-day 12, use separate linear scales arranged linearly one above the other, the hour being indicated by the position of the scale within which the current minute value is displayed by means of an optical marking. To facilitate the reading of the displayed hour by their position within the 12 scales subgroups are formed with 3 scales.

The US Pat. No. 6,693,606 B1 shows a computerized method for displaying and recording measurable quantities including time information. According to FIG. 2 the display takes place within an inner and an outer block groups, each consisting of 12 concentrically arranged blocks, with the two block groups also displaying correlating and non-correlating measured values. In one embodiment, it is proposed to display both the time history of the year and the day such that the outer block group indicates the months and days and the inner block group the hours and minutes, with the position of the currently displayed block within the In each circle arrangement, the measured value (month or hour) and the degree of color change within the block represent a subunit of the measured value (day or minute) cumulatively. While the display of the measured value (month or hour) is accurate due to the unambiguous position determination, the accuracy of the minute representation is limited by the limitation of the scale to a maximum of the radius of the circle arrangement in each case severely.

It is also known from the published patent application DE 3838407 the radial arrangement of 720 display points for the 720 minutes of a 12 hour display around a common center, with each 15 display points forming a beam from the outside to the center so that the display moves inward / outward about the center of the scale and the overrun time separate display points is displayed.

Also the DE 10 2004 058 246 A1 shows a time indicator indicating the hour and minute according to a 1-hand (hour) clock by the course of the minute course within the hour position of the hour to be displayed and the time-dependent next is displayed. The D3 proposes to represent the minute course between the two time-determining hour positions along any geometric curve.

Conventional displays have the disadvantage that, on the one hand, a certain span of variable values must be able to be displayed, and, on the other hand, a certain display accuracy is to be achieved. Both requirements can usually not be met simultaneously if the scale length should remain in justifiable, in particular at a glance intuitively detectable frame. Examples of variables for which these framework conditions apply are, in particular, the hours and minutes of the (daily) time.

Typically, the problem is addressed such that a partial display indicates a larger unit of variable value (eg, hours), a second partial display indicates a smaller unit of variable value (eg, minutes), so that only both partial displays together provide a sufficiently accurate display. A disadvantage here is that simultaneous intuitive capturing of both partial displays can be made difficult at a glance, and In particular, it can also lead to a confusion of the two partial advertisements, in particular if the ads are kept as discreet as possible, ie small.

The conventional linear-analog displays have the disadvantage of using a scale for each variable value to be displayed (for example, hour and minute) that the spatial distance of the respective current value specification makes it difficult to intuitively record the total value, which is the disclosure, for example DE 29504124 with respect to the numerically accurate detection of the position of the displaying scale. Other known linear analog displays, such as the published patent application DE 3838407 require a lot of space for the optical display elements and are therefore not suitable for use in worn on the body clocks, such as a wristwatch.

The time displays described are monofunctional in that they only display the time. In particular, they are not suitable for time display in jewelry pieces, since the general viewing habits of the commonly used pointer elements, display surfaces or scale arrangements the function "clock" always over the function of "trinket" in the foreground. Although such watches are known, which are decorated with gemstones and thereby also meet aesthetic requirements, but also in such watches, the time-indicating function is dominant as such. Because the "glance at the clock" is a frequent and recurring activity in everyday life and is unambiguous for the reasons mentioned above, it now represents a body language signal, which is usually interpreted as a sign of impatience. In addition, there are various occasions in everyday life, such as festive evening events or relaxation recreational activities in which the obvious wearing a watch is not desired, for example because a clock does not fit the chosen evening wear or the desired relaxed leisure activities.

• and each individual (hour) scale forms an intersection with at least one other (hour) scale such that it extends beyond that intersection ( Fig. 1a, 1b, 2a, 2b, 3a, 3b ), wherein in the arrangement.

Advantageous embodiments of the invention are characterized in the subclaims.

Time indicator according to the first aspect

Advantageous characteristics of the time indicator, each with a linear or curve-linear scale for each hour to be displayed, the scale arrangement according to a circular or elipsenfömigen or approximately circular or elipsenfömigen or closed in accordance with a rectangular or trapezoidal or diamond-shaped or approximately rectangular or trapezoidal or diamond-shaped analog hourly arrangement.

In the case of, for example, circular or elliptical hourly arrangements, it is advantageous to store the scales in such a way that the scales form a common center over which they extend, whereby only the geometrical position of the scale enables insiders to intuitively record the indicated time at a glance, for non-initiated but not obviously the time is displayed because the time display contrary to viewing habits is not radial or undulating about the center but beyond this, or not in juxtaposed linear scales with the same geometric orientation, and the scale arrangement not on a close to the usual time displays. This applies equally to the arrangement of the scales that do not form a common center.

According to the invention, the discretion is increased by not indexing the scale arrangement and / or the current scale, whereby for non-initiates, the cumulative display appears to migrate within the display area without a reference point.

For example, in circumferentially rectangular scale arrangements, it is advantageous to arrange the scales at the respective edge lengths so that each accommodates the same number of hour positions; or in the case of a 12-hour arrangement at two opposite edge lengths in each case 5 and at the other opposite two (12/6 or 3/9) to arrange; or to arrange only at two opposite edge lengths in each case the same number of hour positions.

If two hour positions have scales with the same geometric position, the invention provides to display the minute representation of these hour positions in a common scale with changing starting point of the minute display, whereby in the cumulative minutes display the hour is indicated by the visible starting point in each case without a mistake. For punctual highlighting, the geometric position of the scale within the overall figure and thus the two possible hour positions is indexed for initiates, whereby the current hour is recognized intuitively by time-bound everyday events such as brightness or darkness of the halves of the day, mealtimes or working rhythms.

In order to increase the discretion of the time display has been proven, for example, in a 12 hour display 6 scales according to their geometric position in a closed-analog hourly arrangement next to each other or above each other, each scale corresponding to the two geometrically opposite hour positions.

The invention provides, in particular for punctual highlighting of the current minute value, to additionally display the current hour by means of distinguishable emphasis means within the scale or by means of additional emphasis means in the immediate spatial proximity to the starting point of the minute indication. If the current hour is indicated separately, the invention also contemplates using the minutes for detailed display of minute values by displaying within the scale the minute value represented by the position of the hour indication, respectively, according to a closed-analog display. in the case of a 12 hour display at the "hour 1" position, the minute value "5", whereby the minute values "5-10" are then displayed linearly within this scale.

To increase the reading accuracy, the invention proposes for each hour to display two, three or four scales next to each other, each having a specific, preferably represent the same length of the full hour. When using 3 "minute" scales, it is advantageous to control the display in such a way that each scale represents a quarter of an hour and the minute course of the last quarter of an hour is displayed together in all three scales.

To increase the reading accuracy, the invention further proposes to arrange for each hour to be displayed a scale with common start and end point on the hour position to be displayed, the scale is preferably formed of linear or curve-linear sub-segments representing a particular leg of the hour, for example the quarter hours by means of 4 equally long sections.

Has proven useful when using scales formed from linear or curve-linear sub-segments to arrange at least one connection point of the sub-segments on another hour to be displayed position.

It has proven to be advantageous to arrange a screen provided with one or more openings in front of the display and to shift as a function of time so that in each case the, the current time indexing scale is made visible through the opening of the screen.
