Clock with dial with time and quarter display

The invention according to the utility model relates to a clock with a dial with hour, minute, second, and possibly date and location display, wherein the dial is provided with a 24-hour division and the hour hand makes a movement in 24 hours and wherein at least one rotatable ring with a division is arranged on the circumference of the dial.

Clocks with numeral dials of the type mentioned at the beginning are known from the star*·! of technology.

The object of the invention is to develop a clock with a dial of the generic type in such a way that, in addition to the time display of the local time, the local ^times and also the location according to longitudes can be read in a simple manner.

To solve the problem , it is proposed to provide the rotating ring 1 with a scale which corresponds to the division of the longitudes of the earth and to project onto the dial 4 the northern or southern hemisphere with longitude division with the poles as the center of the dial 4, with the entry of important cities, whereby with the exception of the scale of the 24-hour division the dial (hemisphere projection) is rotatable.

With the clock according to the invention, it is possible to determine in a simple manner not only the time of the location but also the local times of different places in the northern hemisphere or southern hemisphere in relation to the longitude. Among other things, the hour hand immediately shows not only the local time of the location but also the longitude (place) at which 12 noon is, because the hour hand always corresponds to the position of the sun at 12 noon.

at noon. In addition, with the present invention, by determining the time of the highest sun position (12 noon), the location in relation to the longitude can be read via the hour hand as seen by the observer.

The invention is explained in more detail below in an embodiment and in the drawing:

It shows Fig. 1: A view of the dial display with

Illustration of the Northern Hemisphere

The ^dial display according to the invention has an inner circular area with the image of the northern hemisphere, on which the longitudes are numbered. At the same time, the most important world cities can be assigned to the image of the hemisphere in relation to the longitude division. Both are shown on a rotating circular area, around which a stationary circular ring is provided, with a 24-hour numeral scale, whereby the hour interval is 1/24th of the

The 15 degrees of longitude are divided into 100 degrees of circumference. The rigid hour division ring is provided with at least one outer rotating ring with a longitude division, which is referred to as the squatter ring.

Claims (10)

Gbm registration G 89 06 306.6 of G. P. Clanner-Engelshofen Protection claims: 1. Clock with a dial with hour, minute, second, date and location display, the dial having a 24-hour division and the hour hand making one revolution on the dial every 24 hours, and at least one rotatable ring (1) with a scale (2) corresponding to the division of the longitudes of the earth's hemisphere being provided on the circumference of the dial, and the northern or southern hemisphere of the earth being projected onto the dial (3) with a numbered, equatorial longitude division (4) with the poles as the centre of the dial, with the entry of important cities, cL.g., with the exception of the 24-hour scale, the dial (earth hemisphere projection) being rotatable. I. Clock with dial according to claim 1, characterized in that the outer ring (1) is rotatable independently of the rotatable part of the dial. 3. Clock with dial according to claim 1, characterized in that the rotatable part of the dial is rotatable together with the outer ring (1). 4. Clock with dial according to claim 1 or 3, characterized in that the rotatable part of the dial is rotatable via the outer ring (1). 5. Clock with a dial according to one of claims 1 to 4, characterized in that the hour and/or minute and/or second display is digital. 6. Clock with dial according to one of claims 1 to 5. characterized in that when the northern hemisphere is depicted on •I♦ t · I • ItIl Page 3
On the dial the numbering is clockwise. 7. Clock with a dial according to one of claims 1 to 5, characterized in that when the southern hemisphere is depicted on the dial, the numbering is anti-clockwise or the depiction of the southern hemisphere is shown in mirror image. 8. Clock with a dial according to one of the preceding claims, characterized in that the dial with the northern hemisphere is provided on the top of the clock and the dial with the southern hemisphere is provided on the bottom. 9. Watch with a dial according to one of the preceding claims, characterized in that the case of the watch is transparent and can be viewed from both sides and is in particular watertight. 10. Clock with dial according to claim 1, characterized in that the outer ring (1) is formed in two parts, with one rotatable ring part having the longitude division and the other rotatable ring part having a 24-hour division with a numbering increasing anti-clockwise.
