Abstract

Rotating body with a magnetic coupling, characterized in that a body (e.g. rotating body with spherical shape - also flattened spherical shape or ovalized spherical shape) is kept in a floating state by a controlled magnetic field and rotates around its own axis with the help of a drive (motor) defined orbital period is offset, corresponding to FIGS. 1 to 5.

Description

State of the art:

The term "floating ball" is the technique of bodies controlled by a magnetic field, apparently weightlessly floating in space. A body is made using materials with magnetic properties - e.g. Iron - attracted by an electromagnet and controlled with the help of a sensor (e.g. Hall sensor) so that the magnetic field of the electromagnet weakens the closer the body is to the electromagnet. The magnetic field of the electromagnet becomes stronger as the body moves away from the electromagnet. This keeps the body in a state of limbo.

A clock is designed based on this technology.
The clock is represented by a floating rotating body (ball) that rotates once or twice around its own axis within 24 hours. The floating behavior of the rotating body is generated with the help of a magnetic field of an electromagnet. The rotation of the rotating body is effected by magnetic coupling and a motor.
For example, the current time is marked with a luminous dot on the rotating body. The time digits are shown on the rotating body, see. 1 . A world map can also advantageously be depicted on the rotating body (the rotating body (ball) should rotate to the left [viewing direction from above on the rotating body], because this corresponds to the actual rotation of the earth).

In order to produce a torque for the rotary movement of the rotating body, the magnetic coupling between the electromagnet and the rotating body is accomplished by an iron bracket. As a result, the magnetic force effect on the rotating body is distributed not only to one, but to several points, see. 1 and 2nd . To increase the magnetic effect, magnets (so-called permanent magnets) can also be used in the rotating body, see 3rd .

A motor (this can be a synchronous motor with gear or stepper motor, for example) turns the iron bracket 1 rotated. The iron orbital period 1 must be exactly 24 hours or 12 hours. The rotating body rotates with the magnetic coupling.
The electromagnet is mounted in such a way that it does not have an iron bracket 1 rotates, so slip rings for the power supply of the electromagnet are avoided.

The illuminated dot on the rotating body can be scanned with a weak laser, e.g. used in laser pointers. The luminous point can also be generated by a conventional incandescent lamp or light-emitting diode with lens optics.

4th shows the exemplary accommodation of motor, iron bracket 1 , Electromagnet, sensor and light source in one housing.

1. a) Bei der wahrscheinlich kostengünstigsten Variante dient ein Einstellschlitz im Drehkörper zur Zeiteinstellung. Hier kann z.B. mit einem Schraubendreher ein Stab und mit ihm Eisenbügel 2 (s. 2) bzw. die Magnete (s. 3) im inneren des Drehkörpers verdreht werden. Hierdurch kann die Stellung von Eisenbügel 1 mit Eisenbügel 2 bzw. der Magnete und der aktuellen Uhrzeit, welche durch den Leuchtpunkt angezeigt wird, in Übereinstimmung gebracht werden.
2. b) Eine weitere Möglichkeit wäre, die Uhr mit einer Elektronik automatisch auf die richtige Position einzustellen. Hierzu wäre entweder ein Uhrenmodul im Gehäuse, welches auf herkömmliche Weise durch Tasten eingestellt wird, oder ein Funkuhrenmodul erforderlich. Für den Motor bzw. Eisenbügel 1 wäre zur Winkelerfassung ein weiterer Sensor erforderlich. Eisenbügel 2 (s. 2) bzw. die Magnete (s. 3) müssten in einer feste, definierten Position - also in einem bestimmten Winkel zur Drehrichtung des Drehkörpers - im Drehkörper befestigt werden, z.B. durch Kleben. Stab, Spange und Einstellschlitz (s. 2 und 3) werden hierbei nicht benötigt.
3. c) Hierbei kann mit Hilfe von zwei Tasten im Gehäuse per Knopfdruck ein schneller Rechts- oder Linkslauf des Motors ausgelöst werden, so dass der Drehkörper schnell in die Position gebracht werden kann, wo der Lichtpunkt auf die aktuelle Zeit weist. Die Anfangsstellung von Eisenbügel 1 oder Eisenbügel 2 bzw. der Magnete muss hierbei nicht erfasst werden, d.h. Eisenbügel 2 bzw. die Magnete können innerhalb des Drehkörpers fest eingebaut werden (z.B. durch kleben), die Stellung in Drehrichtung ist hier beliebig. Stab, Spange und Einstellschlitz (s. 2 und 3) werden hierbei nicht benötigt. Zwischen Kostenaufwand und Bedienfreundlichkeit ist dies wahrscheinlich der beste Kompromiss.

There are several ways to set the clock to the current time:

1. a) In the probably cheapest variant, an adjustment slot in the rotating body is used to set the time. Here, for example, a rod can be used with a screwdriver and an iron bracket with it 2nd (see 2nd ) or the magnets (see 3rd ) are rotated inside the rotating body. This allows the position of iron bracket 1 with iron bracket 2nd or the magnets and the current time, which is indicated by the illuminated dot, are brought into agreement.
2. b) Another option would be to automatically set the clock to the correct position using electronics. This would require either a clock module in the housing, which is set in the conventional manner using buttons, or a radio clock module. For the motor or iron bracket 1 another sensor would be required for angle detection. Iron bracket 2nd (see 2nd ) or the magnets (see 3rd ) would have to be fixed in a fixed, defined position - i.e. at a certain angle to the direction of rotation of the rotating body - eg by gluing. Rod, clasp and adjustment slot (see 2nd and 3rd ) are not required here.
3. c) With the help of two buttons in the housing, a quick right or left rotation of the motor can be triggered at the push of a button, so that the rotating body can be quickly brought into the position where the light point points to the current time. The initial position of iron bracket 1 or iron bracket 2nd or the magnet does not have to be detected here, ie iron bracket 2nd or the magnets can be permanently installed within the rotating body (e.g. by gluing), the position in the direction of rotation is arbitrary here. Rod, clasp and adjustment slot (see 2nd and 3rd ) are not required here. This is probably the best compromise between cost and ease of use.

Another application example would be the projection of the time onto the rotating body by a so-called watch projector (watch projectors are state of the art). The clock projector could be parallel to the light source (see 1 and 4th ) work or replace them.
When displaying the world map on the rotating body, the luminous point or the projected time could then mark the point on the world map at which the sun is currently at its highest position (midday).
