Definitions
- the present invention relates to a rotary attachment for a watch drive according to the preamble of claim 1.
- the common embodiment here has a drive with a clock generator which drives a gear train in accordance with the times.
- a gear train Connected to the gear train are pointer shafts that are partially pushed into each other and are firmly connected to corresponding pointers.
- a dial Between the gear train and the pointer there is a dial with corresponding holes through which the pointer shafts run.
- the glass on the top of the case is connected to the case by a bezel. There is also a cover on the underside of the housing. The housing is therefore accessible from above and below.
- All housings have a side hole through which an adjusting shaft runs, with which the hands are brought into a corresponding position via a gear train, which indicates the current time.
- a bracelet is usually attached to the case to attach the watch to the wrist. This is available in a wide variety of designs and materials, for example made of steel, leather or other.
- wristwatches which, instead of the pointer, have rotating disks on which corresponding markings are located.
- the position of these markers in relation to the dial markers visualize time for the viewer.
- An image of the continents is usually located on the rotating disc, the position of the continents in relation to the dial markings reflecting the corresponding time at the respective place in the world.
- Versions are also known in which place names of the world are plotted on the rotating disk, for which the respective time can be specified on the basis of the markings on the dial.
- the glass can cause reflections that affect the legibility of the time.
- a rotary attachment for a watch drive consist of a drive plate which is connected to the housing by a bearing, the drive plate being driven by a conventional clockwork, characterized in that between the drive plate and the housing at least one drive ring is connected to these by means of storage is and a magnetic coupling is arranged between the clockwork, the drive plate and the drive rings.
- the invention is intended to improve the visualization for clocks by switching off parallax and reflexes.
- the dial, glass and hands of a conventional watch are eliminated.
- the driver disks and driver rings are located on the surface of the wristwatch and rotate about individual or common axes that are perpendicular to the disk or ring surface. They are connected to each other and to the housing via appropriate bearings, which allow mutual rotation with the least possible friction.
- a first magnetizable disk, a second magnetizable disk, at least a first permanent magnet and at least a second permanent magnet are parts of a magnetic coupling between the drive disk and the driving disk, the force distribution between the permanent magnets being such that there is only one position of the driving disk without external influence in relation to the drive pulley.
- a first magnetizable ring, a second magnetizable ring, at least a first permanent magnet and at least a second permanent magnet are parts of a magnetic coupling between the drive ring and the driving ring, the force distribution between the permanent magnets being such that there is only one position of the driving ring without external influence in relation to the drive ring.
- the magnetic coupling consists of two superimposed disks or rings, the drive disk or the drive ring and the drive disk or the drive ring, permanent magnets corresponding to the opposite permanent magnets being attached to each disk or ring and thus the drive torque from the drive disk or the drive ring to the Driving plate or the driving ring is transmitted.
- the maximum transmissible torque between the drive disks and drive rings and the drive disks and drive rings is influenced by the size and design of the drive disks and rings, drive disks and rings, the permanent magnets and the distance between the magnets. If the maximum transmissible torque between the two disks is exceeded by a torque based on undesired external influences on the driving disk, the disks move against one another.
- the maximum transferable torque between the drive and drive plate is to be designed in such a way that the accuracy of the clock, which is loaded by external influences on the drive plate, is within an acceptable tolerance.
- a further advantageous embodiment provides that, depending on the need, there are no one or more driving disks and no, one or more driving rings which rotate individually about their own vertical axis or, depending on the application, in some cases have common vertical axes.
- a general visualization is not only possible through a fixed configuration of drive plates and rings, but also through any position and number of drive plates and drive rings on the surface of the rotary carrier.
- a radial magnetic coupling which minimizes the load on the bearings.
- This object is achieved in such a way that a radial magnetic coupling consisting of an outer ring, an inner ring, magnets, a hood and a housing, characterized in that the outer ring and the inner ring consist of magnetizable material and both rings can rotate relative to one another and around a common axis and on the outer ring radially inward one or more magnets are attached and on the inner ring radially outward one or more magnets are attached, the magnets on the respective circumferential halves of the outer ring and the inner ring having opposite polarity and in that between the magnets of the outside and the Inner ring attached a hood made of non-magnetizable and magnetically permeable material and is firmly connected to a housing.
- the magnetic coupling is constructed in such a way that the magnets of the magnetic coupling are applied to magnetically conductive rings which additionally increase the magnetic force within the magnetic coupling due to the closed magnetic circuit resulting from this design.
- the magnets on the respective circumferential halves of the inner and outer ring have opposite polarity and therefore the magnets of the inner and outer ring can only assume one position corresponding to one another.
- a further advantageous embodiment provides that the drive magnets can be controlled and the magnetism can be induced is, whereby the drive plate is positioned accordingly and the drive of a conventional clockwork is omitted.
- drive disks and drive rings can be rotated in a time-conforming manner via the permanent magnets by means of a time-compliant actuation of controllable magnets on a drive disk, which, however, is then fixed, i.e. does not rotate.
- Figure 1 is an illustration of the wristwatch with a rotating attachment.
- Figure 2 is a basic representation of the cross section through the rotary attachment.
- FIG. 3 shows half of a cross section through the rotary attachment, the other half being symmetrical to the vertical axis A.
- Figure 4 shows a possible positioning and shape of the drive magnets.
- Figure 5 and Figure 6 shows the design of a radial magnetic coupling for reducing axial magnetic forces. Description of drive pulley 2
