    专利说明:

    The invention relates to a component for clocks which, when installed, is rotated or pivoted about an axis with normal operation at an angular velocity greater than 0.105rad / s and / or with a periodically changing direction of rotation.
    The aim of the use of light in or on a clock can be on a functional level by making light-emitting pointers or illuminated dials facilitate reading of the time or other data in the dark or even enable it in the first place. Illuminated components on or in watches can also make the aesthetic and emotional side appealing and create visual effects. Slowly moving or stationary components such as hands or dials that emit light have been known for a long time and are state of the art. In these cases, phosphorescence (afterglow, e.g. based on doped strontium aluminate) or tritium gas light sources (also GTLS or Gaseous Tritium Light Sources) in the form of mostly round glass tubes are typically used to emit the light.
    For fast moving components of clocks, however, a design is very difficult to implement, which enables an active emission of light from these components. Up to now, illuminated components or passively luminous components have been proposed, for example the use of passive phosphorescent paints as a direct application of paint to a restlessness or restlessness spring. The production of a 3D element from the phosphorescent paint has also been proposed in DE 212014000245U1. In EP 2904458B1, EP 2717103B1, CH 711961A2 or CH 714532B1, passive lighting options either by backlighting moving parts, mostly unrest springs, are disclosed. A solution with phosphorescence (afterglow) has also been proposed, for example, in US 2017285575A1 or EP 3226082A1.
    In CH 714514A2bzw. US 2019196408A1 discloses a new, very complex manufacturing method in which recesses can be made on the balance using inserts in the tool, which is therefore very complex and expensive, in which, for example, tritium gas light sources can be inserted. In a special alloy (based on platinum or palladium, with shaping in the amorphous or partially crystalline state) and under special manufacturing conditions (e.g. with precise temperature control), these weakenings can be generated in the balance wheel, in which conventional tritium tubes are then placed perpendicular to the level of the frost . According to the current state of industrial technology, the length of such a tube is significantly greater than the diameter (L / D ratio> 2), especially in the sub-millimeter range, so that installation is difficult as a result. Other active or self-luminous lighting for relatively fast moving (0.5 to 10Hertz range) components of watches are not implemented due to the high weight or the large dimensions of the active lighting elements.
    The object of the present invention was to overcome the disadvantages of the prior art and to provide a component for clocks which, while being simple and inexpensive to manufacture, enables active lighting even for rapidly moving components.
    This object is achieved by a component according to the claims.
    The device according to the invention is characterized in that at least one active light source, preferably a tritium gas light source, is attached to the surface of the component, which preferably rotates or pivots in its entirety in the manner of a rigid body. Instead of a new, expensive manufacturing process for the watch components and without the need for subsequent processing and the weakening of these components, which is often associated with this, in order to prepare them for the use of light sources, the present invention provides for the quick and easy fixing of a self-illuminating light source on the surface of a conventional standard component.
    Preferably, the active light source is firmly attached to the component. In this way, any type of weakening of the component can be reliably avoided and standard components can be used without any further processing.
    According to a further optional feature of the invention, a component with a rotation or pivot axis and at least one section proceeding from this axis is characterized in that the light source is positioned on a section proceeding from one of the axis.
    In the case of a component with a structure that is rotationally symmetrical about an axis of rotation, a plurality of light sources is preferably arranged rotationally symmetrically on the component. This minimizes the influence on the imbalance and maximizes the light yield.
    According to a preferred embodiment of the invention, the light source is a self-illuminating light source. A tritium gas light source is preferably used for this purpose. With a small overall size and low mass, this provides a particularly long emission of light without any external energy supply. The manufacture of such tritium gas light sources also allows the application according to the invention to mass-sensitive components of clocks, such as the balance, which are integrated in the clockwork and additionally have little space in the available installation space (installation height).
    In order to influence the moving component as little as possible and to make active lighting of the component possible with the given space, the light source has a maximum length of 4mm. The length of the active light source is preferably limited to a maximum of 2mm. The largest transverse dimension for this is limited to a maximum of 2mm, and is preferably even a maximum of 0.6mm. The ratio between length and a transverse dimension of the light source is typically between 2 and 10.
    Another embodiment according to the invention is characterized in that the tritium gas light source has a height between 0.1mm and 0.6mm parallel to the axis of the component. The width B of the light source is preferably in a range between 0.1 mm and 1.5 mm. According to the invention, the ratio of length to height of the tritium gas light source is in the range between 2 and 10.
    In order to influence the movement of the component as little as possible and also to keep the influence on the imbalance low, it is preferred not to exceed the weight of the light source 1 mg.
    According to a particularly advantageous embodiment of the invention, the component is designed as a balance with a circular hoop, a central hub and at least two arms arranged in a rotationally symmetrical manner. This is then characterized in that at least one active light source is attached to the surface of the hoop or at least one arm.
    Preferably, at least one light source is attached to the surface of at least one of the arms. A plurality of active light sources are preferably distributed symmetrically around the hub on the arms.
    Another embodiment of the invention provides a component designed as an anchor or hammer for the repetition, and this is characterized in that at least one active light source is attached to its surface.
    For a better understanding of the invention, it is explained in more detail with reference to the following figures.
    In each case, in a greatly simplified, schematic representation: FIG. 1 shows a plan view of a restlessness designed according to the invention with applied tritium gas light sources; Fig. 2 shows a longitudinal section through the unrest of Fig. 1 along the line II-II; Fig. 3 shows a cross section through an arm of the unrest of Fig. 1 along the line III-III; and FIG. 4 shows schematic representations of tritium gas light sources for use in accordance with the present invention.
    At the outset, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, and the disclosures contained in the entire description can be transferred accordingly to the same parts with the same reference numerals or the same component names. The position details selected in the description, such as above, below, to the side, etc., also relate to the figure immediately described and shown and these position details are to be transferred accordingly to the new position in the event of a change in position.
    In Fig. 1 is shown as a preferred embodiment of a component designed according to the invention, a three-armed balance 1 for a wristwatch. However, the invention is not restricted to the embodiment variant specifically shown. In any case, the invention is intended for components that rotate in their entirety around an axis in the manner of a rigid body and / or are pivoted around an axis or a fastening point.
    The balance 1 comprises a circular hoop 2 which is connected to a central hub 4 via three radial arms 3. The axis of rotation A runs through the center of the hub 4 and thus the balance 1, which is a fast moving component of the watch that rotates around the axis A in alternating directions. The angular velocity of this rotation of the balance 1 considerably exceeds the value of 0.105 rad / s.
    On the surface of the arms 3 are applied in the radially outer area, immediately following the hoop 2, self-luminous tritium gas light sources 5 as a preferred variant for active, self-luminous light sources and fixed on the arms 3 by a material connection. Preferred examples of connection methods are gluing, bonding, soldering and welding, including all subtypes of these material connections. In FIG. 3, an arm 3 with a tritium gas light source 5 fixed by means of an adhesive 6 is shown in cross section.
    Other types of active light sources that can draw their energy from a radiation field, for example in the form of RFID devices, would also be conceivable.
    The placement of the tritium gas light sources 5 on the arms 3 of the unrest 1 exploits the existing symmetry of the unrest 1 and at the same time reduces the influence on the inertia and thus on the imbalance of the unrest 1, since the light sources are placed closer to the axis of rotation A, compared to an embedding in the hoop 2 of unrest 1.
    The accuracy of the balancing relates essentially to the mass of the balance wheel 2, which is typically between 0.05g and 0.2g. Accordingly, unrest 1 is balanced to well below 1 mg, typically down to approx. 0.1 mg. It follows from this that disturbances on the outer hoop are significantly less sensitive to imbalances below 1 mg. The tritium gas light sources 5 according to the invention with their maximum mass of 1 mg are therefore so light that the influence on the imbalance on the balance balance can no longer be felt. Another possibility is to place the light source further towards the center of the unrest 1 in order to reduce the influence of the mass of the light source on the moment of inertia.
    In other applications, too, such as for an armature, a symmetrical, inertia-minimal or inertia-neutral arrangement of the light sources must be ensured. Depending on the mass or inertia of the balance wheel 2 and the precision of the fixation of the tritium gas light sources 5 on the arms 3 of the balance wheel 1, small imbalances may occur. As before, these can be corrected by balancing the unrest 1 at the end of the mechanical manufacturing process or, in the case of smaller unrest, after the light source has been fixed by mechanical processing.
    As can be seen in FIG. 3, the connection can be made, for example, by gluing with an adhesive 6. By attaching the tritium gas light sources 5 to each of the three arms 3, a rotationally symmetrical arrangement with minimal influence on the imbalance of the unrest 1 is given.
    The light sources can in principle be attached to each side of the component or to its subsections. For example, the arrangement of the tritium gas light sources 5 in relation to the plane of rotation of the unrest 1 is possible both on the upper side and on the lower side, as is a combination in which light sources are arranged on both opposite sides. The light sources can also be mounted on surfaces of the components according to the invention for clocks that are oriented transversely or inclined to the said plane of rotation.
    These tritium gas light sources 5 are, for example, in the form shown in FIGS. 4a and 4b, automated and can be produced with high reproducibility. The high precision in diameter, length, wall thickness and thus in mass results in a high reproducibility of the already small influence on the inertia of the unrest 1 and, in the case of a rotationally symmetrical arrangement, only introduces a hardly measurable additional imbalance.
    Typically, the diameter D in the case of cylindrical tubular tritium gas light sources 5, as shown in FIG. 4a, is between 0.1 mm and a maximum of 0.6 mm. The length is preferably limited to 4 mm, it being particularly preferred if the length is a maximum of 2 mm and the ratio between length and diameter is in a range between 2 and 10. The particularly preferred length L of the tritium gas light source 5 is a maximum of 2 mm.
    For elongated cuboid tritium gas light sources 5 as in Fig. 4b, a height H (i.e. the dimension parallel to the axis A of the balance 1) between 0.1mm and 0.6mm is preferred. The width B, on the other hand, is in a range between 0.1mm and 1.5mm. The range between 2 and 10 applies here for the ratio of length to height of the light source 5.
    Together with a wall thickness in the range between preferably 0.01 mm and 0.1 mm, a preferred range results for the mass of the tritium gas light source 5 between 0.05 mg and 1 mg, preferably at a maximum of 0.5 mg.
    The very small dimensions and the low mass of the tritium gas light sources 5 which are preferably used according to the invention enable use on small, fast-moving components of the clocks, such as balance 1, armature, or additional complications such as hammers for repetition, without having to make recesses. They can therefore be used for conventionally manufactured components that either move quickly, preferably at more than 0.105 rad / s, and at the same time or alternatively move with a periodically changing direction of rotation.
