Description

Uhrenbewegerwinder

The invention relates to a watch winder for mounting automatic watches and the like.

From the prior art, the use of mechanical devices known as watch winders is known for mounting automatic watches or mechanical watches with automatic winding and keeping them operational even when not worn. A conventional watch winder slowly turns an automatic watch mounted on it about a single rotor axis. By the movements of the watch case and the rotation of the rotor triggered thereby, a torque is exerted on the Aufziehmechanismus of the clock and the clock is wound.

From the US 7,530,733 B2 an advanced watch winder is known, which additionally rotates the automatic watch mounted on it by a further rotor axis, to put the clock in a circular wobbling motion.

Such an arrangement has the disadvantage that the clock is rotated in an artificial form, which does not correspond to the complex everyday movements of a human wearer, which at the expense of energy and time efficiency of the Aufziehprozesses affects.

The invention is therefore an object of the invention to provide a watch winder, which mimics the varied positions and relative rotational movements of the human wrist.

This object is achieved by a watch winder with a frame and three within the same rotatably interconnected rings, wherein at least one of the rings driven by a motor and the innermost ring is provided with a holder for receiving the clock. The term "ring" is understood to mean any closed, essentially annular object.

Such an arrangement makes it possible to put the clock located therein in a random rotational movement about three potentially different axes of rotation, wherein the axes of rotation of the respective inner ring is determined by the orientation of the respective outer ring surrounding it and so the generated rotational movement has a large variability, which approximates that of the human wrist.

In addition, the movement described allows a particularly advantageous presentation of their subject clock, which can be perceived with unchanged viewer position over the duration of the rotation process from different angles. Especially valuable collector's items can be kept so presentable and ready to wear.

A preferred embodiment of the invention provides that at least three or more rings are nested in each other, which are rotatably connected to each other via respective axes of rotation, so that, for example, in three rotatably connected rings a gimbal suspension is provided. In addition, four or more rings can be connected to each other and rotatable with each other.

Preferably, at least the first, second and / or third ring is rotatably mounted about the respective axis of rotation by 360 °. Preferably, the nested rings are each arranged to be rotatable through 360 °, whereby a random rotational movement for the holder of the clock is generated during a drive movement, so that due to the outside of a crossing point of the three arranged around several axes of gravity centers of the clock, which fastened to the holder is, the complete rotational movement of the clock is achieved in different directions. This generated motion comes very close to the hand movement compared to a staggering movement according to the prior art.

A preferred embodiment of the invention provides that the first axis of rotation is perpendicular to the second axis of rotation and the third axis of rotation is arranged offset by 45 ° to the second axis of rotation. Such an advantageous arrangement of the axis of rotation is also known as cardanic suspension and is used approximately in gyro compasses. There, it serves to align a rapidly rotating gyroscope so that its axis of rotation is parallel to the earth's surface. However, in conjunction with the drive mechanism described, the described suspension allows a deliberately induced chaotic rotational movement which allows numerous positions and relative rotational movements of the clock in the inertial space.

According to an advantageous embodiment of the invention it is provided that the first axis of rotation, the second axis of rotation and the third axis of rotation have a crossing point which is located in the holder receiving the clock. Such a configuration of axes of rotation and support allows a bearing of the clock, whose translational movements are minimized in the inertial space in this way and almost exclusively rotational movements are generated.

According to a preferred embodiment of the invention adjacent rings are rotatably connected by at least one pin, wherein the outermost ring is rotatably connected by a pin to the frame. The term "pin" in the context of this application comprises any - preferably cylindrical - extension of a ring or the frame, which serves for its mechanical connection with another component of the watch winder. The thus arranged pins thus define the three axes of rotation of the device, without destroying the delicate appearance of the ring assembly and the aesthetic impression of acting as a "free-floating" in the center clock.

In order to further increase the stability of the device engage on the respective ring preferably in pairs in diametrically opposite arrangement pins, so that the axis of rotation of each ring passes through the pair of pins overlapping it.

According to an advantageous embodiment, the holder for receiving the clock is carried by a connected to the innermost ring and projecting radially into this rod. In favor of a more stable bearing of the clock and to prevent bending of the rod this can also pass diametrically through the innermost ring, wherein the holder would be located near the coincident with the center of gravity of the device center of the rod.

Furthermore, it is preferably provided that the rod are detachably arranged to the third ring and / or the holder detachably to the rod. As a result, a mounting and removal of the clock on and from the holder can be made possible in a simple manner.

According to a first embodiment, the frame is formed substantially annular and the other rings are arranged concentrically thereto. Alternatively, the frame and the rings may be polygonal. As a result, different optical effects can be achieved. The operating principle for initiating the rotational movement for the watch via the cardan suspension is retained.

It is preferably provided that the motor acts on the first ring and has a drive element for initiating the rotational movement. This can be variously designed.

For example, the drive element has a drive axle, which lies in the first axis of rotation or forms the first pin. This may make it possible that from the outside the introduction of a rotary drive is not visually apparent, creating a particularly aesthetic design is created.

Alternatively, a magnetic drive can be provided, which is also to be understood in the sense of an engine.

In order to obtain the filigree overall impression of the ring assembly, the motor is preferably arranged outside the frame.

Furthermore, it is preferably provided that the frame is received by a base with a base, in which the motor is arranged. As a result, the motor can be invisibly integrated from the outside in the watch winder, whereby the drive technology does not appear, but only a rotation of the rings is visible to each other.

A further preferred embodiment of the watch winder provides that the base of a standing surface opposite a concave receiving surface has, in which the frame is arranged. As a result, a stable configuration and also an example. Schmalbauende arrangement can be created at rest.

The invention and further advantageous embodiments and developments thereof are described in more detail below with reference to the examples shown in the drawings and explained. The features to be taken from the description and the drawings can be applied individually according to the invention individually or in combination in any combination. Show it:

FIG. 2 is a side view of the embodiment of FIG. 1,

FIG. 3 is a front view of the embodiment of FIG. 1 during a rotational movement;

Figure 4 is a side view of the embodiment of Figure 1 during a rotational movement and

FIG. 1 shows a front view of a watch winder 11 according to the invention. This watch winder 11 has a base 12 with a base 17 and a concave receiving surface 18. This receiving surface 18 receives a circular arc-shaped portion of a substantially annular frame 19 along a center angle of approximately 120 ° and is rigidly connected to this frame 19. Alternatively, it can also be provided that the base receives the frame 19 by one, two or more support points quasi self-supporting.

Within the frame 19 and to this concentrically a first ring 20, a second ring 21 and a third ring 22 are arranged equidistantly, the radii gradually decrease. Each preferably

metallic ring

20, 21, 22 is thereby spaced from the ring adjacent to it and the outermost ring 20 to the surrounding frame 19 to the extent that between them an air gap remains, the width of which, for example, about the difference of external and inner diameter of a

single ring

20, 21, 22 or the frame 19 may correspond. The third and thus innermost ring 22 has a diametrical leading rod 23 with a comparatively small outer circumference or diameter, which near its center, which coincides with the centers of the

rings

20, 21, 22 and in particular the frame 19, a holder 24 for receiving a clock 25 carries.

The frame 19 has on its inner surface a diametrically arranged

first pin pair

26, 27, between which the first ring 20 rotatably supported, so that a ring 20 associated with this first axis of rotation 35 extends through the first pair of

pins

26, 27 overlapping it. A second pair of

pins

28, 29 and a

third pin pair

30, 31 are provided in a corresponding arrangement on the inner surfaces of the first ring 20 and the second ring 21, where they carry the second ring 21 and third ring 22 and thus simultaneously define a second ring 21st The

first pin pair

26, 27 and the

second pin pair

28, 29 are arranged offset at right angles on the inner surfaces of the frame 19 and the first ring 20, so that the first axis of rotation 35th is perpendicular to the second axis of rotation 37. The third pair of

pins

30, 31 in turn is on the inner surface of the second ring 21 both the first pair of

pins

26, 27 and the second pair of

pins

28, 29 offset at an angle of 45 ° and in extension of - in the rest state shown horizontal - rod 23rd arranged. The diameter of the pins 26 to 31 can remain slightly behind that of the rod 23, so that the pins 26 to 31 do not dominate the visual appearance of the construction.

The holder 24 is positioned on the rod 23 such that the point of intersection of the axes of

rotation

35, 37, 39 coincides with the holder 24.

FIG. 2 shows the embodiment of FIG. 1 in a side view. The width of the frame 19 preferably covers the

inner rings

20, 21 and 22 in a resting state of the watch winder 11. The inner rings 20, 21, 22 may be formed of the same width and / or wall thickness, but are preferably slightly in width and / or wall piece smaller and / or smaller than the frame 19. Alternatively, all rings 20, 21 and 22 and the frame 19 of the width and / or wall thickness ago be the same, resulting in a particularly harmonious appearance. In addition, it can alternatively also be provided that the

rings

20, 21, 22 concentrically arranged one inside the other can also deviate from one another in terms of geometry, and yet they can be rotatable relative to each other via the

rotation axis

35, 37, 39 as a cardanic suspension.

By contrast, FIG. 2 shows that the frame 19 is surrounded by the base 12 and its concave receiving surface 18 approximately in the region of its lower vertical quarter. The base 12 itself is of a depth which provides stable support to the frame 19 therein when it is centered, as shown, between the front and rear surfaces of the base 12 and upright thereon.

FIG. 3 shows a front view of the watch winders 11 in the operating state, that is, during the rotation of the watch 25 located in the holder 24. It becomes clear that the watch 25 largely rests in its center even under the most varied angles of rotation of the

rings

20, 21, 22 and none is subjected to significant translation movement. With regard to its direction of rotation, on the other hand, the clock 25-defined by the current position of the

rings

20, 21, 22 carrying it-occupies very different positions which, in contrast to a conventional watch winder, have a constant uniform distribution over the entire period of use. In this arrangement, the second axis of rotation 37 rotates perpendicular to the first axis of rotation 35. The second ring 29 rotates again at right angles to the axis of rotation 37 and the third ring 22 rotates again at right angles to the axis of rotation 39. This results in this chaotic rotational movement. It should not just aligned as the gimbal for the gyroscope interior and sedated, but the holder 24 perform a chaotic rotation movement to drive the automatic elevator of a mechanical clock 25.

In FIG. 4, the same movement state of the watch winder 11 is again shown in a side view corresponding to FIG. It is clear that the three

rings

20, 21, 22 of approximately the same and over its circumference in each case constant width, for example, behind that of the frame 19 remains about halfway.

FIG. 5 shows a longitudinal section of the stationary watch winder 11 along the plane AA of FIG. 2. In particular, a motor 32 arranged in the base 12 for driving the ring 20 can be seen, which drives a drive force on the first shaft 33 via a drive axis 33 which is congruent with the first rotation axis 35 Ring 20 initiates by putting the first pin 26 or the first ring 20 in a rotational movement. For this purpose, the first pin 26 may be the drive shaft 33 of the motor or be connected by means of a coupling, not shown, with a drive shaft 33 of the motor 22.

The motor 22 may be provided depending on the configuration of the base 12 in the angled arrangement as well as in a directly below the bracket 24 lying arrangement. Alternatively, it is also conceivable that the motor 32 is arranged outside of the base 12 and, for example, lies in a horizontal, in which case the first axis of rotation 35 is likewise horizontal, so that a drive of the first ring 20 can take place. The second and third axes of

rotation

37, 39 are accordingly arranged rotated analogously.

A - not shown in Figure 5 - control unit provides the user different elevator programs for controlling the motor 32 is available. The typical speed of the motor 32 varies between 650 and 900 revolutions per day (UPT).
