Definitions

• This invention consists of a clock according to claim 1.
• this clock has a time display of 24 hours. These are arranged in such a way that a unique, clear time reading or time display is possible, thanks to a device that has a 24-hour rotation.
• the time of day can clearly be distinguished from the night on a 12-part dial.
• this 24-hour clock differs from other 24-hour clocks, in which the time display is always ambiguous; the question remains whether it is, for example, 10 p.m. or 10 a.m.
• the novelty of the invention consists of this clear distinction between day and night.
• - Fig. 1 is the front view of the dial with the two digit systems for day and night time display.
• - Fig. 2 is the front view of the dial with another example of two digit systems.
• 3 is the front view of the dial with another example of two digit systems.
• - Fig. 4 is the front view of the element which has a 24-hour rotation with the two surfaces facing each other.
• - Fig. 5 is the representation of the entire display at 10:00 and normal hour and minute hands.
• - Fig. 6 is the front view of the disc, which has a 12-hour rotation and the two openings through which the Time is displayed.
• FIG. 7 is the section according to I-I of FIGS. 1 and 6 when the element which has a 24-hour revolution lies over the dial and the schematic representation of the elements of the movement transmission.
• 10 is a representation of the two opposing surfaces (4, 5) and how they can be lengthened or shortened.
• - Fig11 is the representation of the position of the two opposite surfaces of the element with a 24-hour rotation also to the openings of the disc (9) at 6:00 a.m.
• FIG.12 is like Figure 11, but at 6 p.m.
• the dial has two number systems for time display, which are in two concentric
• Annular rings are included and each contain 12 hours. However, the night hours are included in one (3), ie exactly the hours: 1 2 3 4 5 18 19 20 21 22 23 24; in the other are Day hours : 6 7 8 9 10 11 12 13 14 15 16 17 included.
• the position of 6 and 18 can be exchanged for aesthetic and functional reasons, which does not change the invention. If the hours 07.00 or 08.00 are regarded as night hours and the hour 05.00 as day hours, you will have to use the two digit systems as shown in Figures 2 and 3.
• Figure 1 in an example for practical reasons: at 6:00 a.m. and 6:00 p.m., the two transitions of the time display or reading are from one system to another, so that the transitions 1 to 24 take place without gaps. This transition and in general the functioning of the invention is made possible and readable by the special display device and contains:
• a 24-hour element (6) which, depending on the mechanism, is located above or below the dial
• the elements 6 and 20 and 9 rotate in the same direction.
• the raw work is available in different versions, e.g. : with a disc with a 24-hour revolution under the dial, or with an hour hand with a 24-hour revolution over the dial. No further description is necessary since this is not part of the invention.
• the element 6 is above the dial.
• Rotation preferably in the form of a disk, is e.g. also completely transparent, with the exception of two areas (4,5), each of which lies above a number system, so that they cover these systems, but only half, ie that each area has an angular opening of 180 °, which covers 6 hours of each system will.
• the two surfaces which geometrically form two semicircular rings, must lie opposite each other, ie the two angles in the center form -x and R 360 °. All of this is fundamental to the position of the element with 24-hour rotation with respect to the dial and with respect to the element with 12-hour. m rotation, the hour hand.
• the two surfaces each in the form of a semicircular ring, can be lengthened or shortened with respect to the angular opening of 180 ° (FIG. 10), depending on the aesthetic or functional requirement.
• This change can be made within certain limits, e.g. this change from the extreme points A and B must not exceed 15 °. If this limit is exceeded, the properties of the invention change; e.g. there is a transition from 4:00 a.m. to 5:00 p.m., or a simultaneous overlap of the two systems, where the time is also displayed.
• the change is complementary, and this also applies to the outermost points B. So if one looks at the two surfaces 4 and 5, each in the form of a semicircular ring, the element that lasts 24 hours - The rotation has (6) at midnight just such that the radius (23) that goes through the center of the semicircle, which corresponds to the day system (4), coincides with the point that corresponds to the time 12:00 and the hour hand (20) will just show midnight, which can be seen on the night system.
• the shape of the element with 12 hours. m rotation, the hour hand can be changed significantly, depending on the model; it can be a simple hour hand that shows the hours on both systems in ⁇ directly, like the pointer 20. There can also be two hour hands of different colors, so that the time on both systems is displayed directly by the one hour indicator matches the color of the system and the other shows the time on the other system.
• the color and functional combinations of the dial with the two surfaces 4 and 5 are numerous. It can also be a disc 9 with two hour indicators.
• the following solution was chosen for reasons of clarity: a disk 9 with the two openings (7, 8), preferably lying between two identical radii are concentric, correspond and correspond to a time unit 13 and 14, in this case equal to 60 minutes of the corresponding number systems 2 and 3, which are on the dial (1).
• These two openings have two hour indicators, 11 and 12, each corresponding to a number system. Starting from midnight, it will take 6 hours to make a quarter turn. At 6:00 a.m. it will be such that the radius (19) is perpendicular to the diameter 18.
• the two hour indicators 11 and 12 at a double speed, will have reached the outermost points B of the semicircular rings and from 6:00 a.m. they will start to exceed them and display the time and the hour indicator 11 will show the time on the now Show exposed day system, while the other system is covered by the other semicircular ring (Fig. 11).
• 6:00 p.m. ie after a further 12 hours, during which the hour indicators 11 and 12 have made one revolution, indicating the time on the daytime system, they reach the outermost points A of areas 4 and 5, which have made half a revolution ( Fig. 12).
• From 6 p.m. the daytime system will be covered and the hour indicator 12 will show the hours on the now exposed nighttime system. Until midnight, and then start again as described.
• the movement on the element 6 is transmitted by the hour wheel 15, which has a 24-hour revolution.
• the movement aaf 9 and 20 is transmitted by the hour wheel 16, which has a 12-hour revolution.
• Minute and hour hands can of course also be attached.
• the dial can lie above or below the element 6, depending on the movement. If it is below, the opposite surfaces 4 and 5 cover the digits. If it is above, it has to be transparent, for example, in order to make the two surfaces visible (4,5); The color of the numbers can align with the two areas. If, according to one variant, you want to carry out the transition from one system to the other between 06:00 and 07:00, e.g. at 6.30am, or using one of the two numbering systems (2a or 3a of Fig.
