By means of such a combination of the movement receiving ring (17) covering the watch movement (22) and having the ball bearing (14) and the rotatable plate (15) which covers the ball bearing (14) with a central centre of gravity and by means of such a connection of the movement receiving ring to the watch movement that the inner components of the watch can only be taken out of the watch with the plate (15), and since the movement receiving ring (17), watch casing (20) and the back of the casing (19) form a casing for the watch movement, on the one hand a more cost-effective production is made possible and on the other hand the decorative elements serving to catch the eye are perfectly guided without elements spoiling the appearance being present. <IMAGE>

Description

Die Erfindung betrifft eine Armbanduhr gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a wristwatch according to the preamble of claim 1.

Unter Innenteile im Sinne des Patentanspruches 1 werden sämtliche Teile der Uhr verstanden, die nicht von außen zugänglich sind. Zu diesen Teilen gehören z.B. Uhrwerk, Werkaufnahmering, drenbare Scheibe, Kugellager, Zeigerwelle, Zeiger.Inner parts within the meaning of claim 1 mean all parts of the clock that are not accessible from the outside. These parts include e.g. Clockwork, movement support ring, drenbare disc, ball bearing, pointer shaft, pointer.

Bei einer bekannten Armbanduhr dieser Art (CH-PS 666 380 G A3) sind zwei vorzugsweise als Scheiben ausgebildete Dekorelemente mit exzentrischen Massen unabhängig voneinander, um eine zentrale Achse frei drehbar angeordnet, in welcher Achse sich zugleich die Zeigerwellen befinden. Dabei ist das eine Dekorelement unterhalb und das andere Dekorelement oberhalb eines gesonderten, das Uhrwerk aufnehmenden Gehäuses angeordnet. Jede Scheibe ist für sich an einem gesonderten Kugellager gelagert. Aufgrund der Anordnung des Uhrwerkgehäuses oberhalb der unteren Scheibe ist eine das untere Dekorelement teilweise verdeckende Werkhalterung erforderlich. Überdies erfordern die zwei beweglichen Scheiben sowie deren Lager eine derartige Bauhöhe, daß es nicht möglich ist, die Uhr flach zu bauen, zumal aufgrund der exzentrischen Massen der Scheiben belastbare lager erforderlich sind. Um das unter der unteren Scheibe angeordnete Uhrwerk zu verdecken, ist ein gesondertes Gehäuse erfoderlich. Zudem ergibt sich beim Zussmmenbau der Uhr eine aufwendige Montage und die Notwendigkeit von Sonderanfertigungen von Uhrenteilen. Bei einer weiteren bekannten Armbanduhr (CH-PS 411 428) sind verzierte Formteile auf mehreren kugelgelagerten, konzentrischen Trägerringen angeordnet, welche ihre Bewgungsimpulse durch die Körperbewegung der Trägerperson erhalten. Auf der nicht sichbaren Unterfläche der Trägerringe können dabei exzentrische Massen angeordnet werden. Eine derartige Anordnung von konzentrischen Ringen erfordert jedoch eine extreme Bauhöhe, die das ganze Aussehen der Uhr beeinflußt.In a known wristwatch of this type (CH-PS 666 380 G A3), two decorative elements, preferably designed as disks, with eccentric masses are arranged independently of one another, freely rotatable about a central axis, in which axis the pointer shafts are located at the same time. The one decorative element is arranged below and the other decorative element above a separate housing that accommodates the clockwork. Each disc is mounted on a separate ball bearing. Due to the arrangement of the clockwork housing above the lower disc, a movement holder partially covering the lower decorative element is required. In addition, the two movable disks and their bearings require such a height that it is not possible to build the clock flat, especially since the eccentric masses of the disks require resilient bearings. A separate housing is required to cover the clockwork located under the lower pane. In addition, when assembling the watch, there is a complex assembly and the need for custom-made watch parts. In a further known wristwatch (CH-PS 411 428), decorated molded parts are arranged on several ball-bearing, concentric support rings, which receive their movement impulses through the body movement of the wearer. Eccentric masses can be arranged on the invisible lower surface of the carrier rings. However, such an arrangement of concentric rings requires an extreme height, which affects the overall appearance of the watch.

Weiterhin ist es bekannt, bei mit einer automatischen Aufziehvorrichtung versehenen Armbanduhren Scheiben anzuordnen, die zumindest zeitweise mit einem Uhrwerk in Verbindung stehen (BE-PS 533 232, FR-PS 1 046 943). Derartige Scheiben sind jedoch einer freien ungehinderten Bewegung nicht zugänglich.Furthermore, it is known to arrange discs in wristwatches provided with an automatic winding device, which are at least temporarily connected to a clockwork (BE-PS 533 232, FR-PS 1 046 943). However, such disks are not accessible to free, unimpeded movement.

Bei einer weiteren bekannten Armbanduhr (CH-PS 609 517) sind die Dekor- oder Schmuckelemente, wie vor allem Diamenten, auf einer Bahn um das Zifferblatt angeordnet. Die jeweils für sich beweglichen Dekorelemente bewegen sich dabei mit radialem Spiel auf der Bahn. Die nicht exakt kreisförmige Bahn der Dekor- oder Schmuckelemente führt jedoch zu einer raschen Abnutzung der Wandungen der Bahn. Überdies kann bei einer solchen Ausbildung das Dekor- oder Schmuckelement seine Wirkung nicht voll entfalten. Siehe auch US-4 734 895.In another known wristwatch (CH-PS 609 517), the decorative or decorative elements, such as diamonds in particular, are arranged on a track around the dial. The decorative elements, each movable for themselves, move with radial play on the track. However, the not exactly circular path of the decorative or decorative elements leads to rapid wear of the walls of the path. In addition, with such a design, the decorative or decorative element cannot fully develop its effect. See also US 4,734,895.

Der Erfindung liegt die Aufgabe zugrunde, eine Armbanduhr der eingangs genannten Gattung derart weiterzubilden, daß einerseits eine kostengünstige Fertigung ermöglicht wird und andererseits die dem Blickfang dienenden Dekorelemente perfekt geführt sind, ohne daß die Ästhetik störende Elemente vorhanden sind.The invention has for its object to develop a wristwatch of the type mentioned in such a way that on the one hand an inexpensive production is made possible and on the other hand the decorative elements serving the eye-catcher are perfectly guided without the aesthetic disturbing elements being present.

Diese Aufgabe wird durch die im Kennzeichen des Patentanspruches 1 genannten Merkmale gelöst.This object is achieved by the features mentioned in the characterizing part of patent claim 1.

Bei einer solchen Ausbildung stören keine sichtbaren Befestigungselemente die Ästhetik der Uhr. Zudem kann eine extrem flache, ästhetische Bauweise erreicht werden. Der Betrachter kann äußerlich nicht feststellen, wie die drehbare Scheibe befestigt ist. Außerdem ist der Einsatz der die Dekor- oder Schmuckelemente tragenden Scheibe sowohl in Herren- als auch in Damen-Armbanduhren universell möglich. Überdies läßt sich die Montage der Uhr mit wenigen Handgriffen bewerkstelligen. Nach dem Zusammenführen von Scheibe, Kugellager und Werkaufnahmering kann das Uhrwerk und die Zeiger mit diesen Teilen verbunden werden und diese Montageeinheit letztendlich in das Uhrgehäuse eingesetzt werden. Aufgrund der flachen und kompakten Bauweise finden größtenteils Standardteile Verwendung.With such a design, no visible fasteners interfere with the aesthetics of the watch. In addition, an extremely flat, aesthetic design can be achieved. The viewer cannot determine externally how the rotatable disk is attached. In addition, the disc carrying the decorative or decorative elements can be used universally in both men's and women's wristwatches. In addition, the watch can be assembled in just a few simple steps. After the disc, ball bearing and movement mounting ring have been brought together, the clockwork and the hands can be connected to these parts and this assembly unit can ultimately be inserted into the watch case. Due to the flat and compact design, mostly standard parts are used.

Dies erleichtert z.B. auch eine wasserdichte Ausführung der Uhr, da verkehrsübliche, wasserdichte Gehäuseböden verwendbar sind.This facilitates e.g. also a waterproof version of the watch, as customary, waterproof case bottoms can be used.

Trotz allem führt die Beweglichkeit der Dekorelemente nicht zu einer Verringerung der Lebensdauer der Teile der Armbanduhr.Despite everything, the mobility of the decorative elements does not reduce the life of the parts of the wristwatch.

Bei einer Ausbildung entsprechend den Ansprüchen 2 und 3 wird mit einfachen Mitteln eine sichere Festlegung des Uhrwerkes im Gehäuse gewährleistet, ohne daß ein zusätzliches Gehäuse erforderlich ist. Diese Ausbildung verhindert auch eine zerstörende Demotage der Uhr, die z.B. dann zustandekommen könnte, wenn bei Reparaturarbeiten versucht wird, das Werk alleine ohne die durch die Scheibe hindurchgreifenden Zeiger zu entfernen.In a design according to claims 2 and 3, a simple fixing of the clockwork in the housing is ensured by simple means, without the need for an additional housing. This design also prevents the watch from being demolished, e.g. could occur if an attempt is made during repair work to remove the movement alone without the pointers reaching through the pane.

Eine Ausbildung gemäß Patentanspruch 5 stellt eine kostengünstige, einfache und dennoch auf Dauer feste Verbindung von Werkaufnahmering, Kugellager und drehbarer Scheibe dar. Ein Auswuchten gemäß einer Ausbildung entsprechend Patentanspruch 6 erhöht vor allem die Lebensdauer des Kugellagers.A training according to claim 5 represents an inexpensive, simple, yet permanent connection of the factory mounting ring, ball bearing and rotatable disc. Balancing according to a training according to claim 6 primarily increases the life of the ball bearing.

Durch eine Sicherungsvorrichtung entsprechend dem Patentenspruch 7 wird vorzugsweise bei Verwendung von Diamanten als Dekor- oder Schmuckelement sichergestellt, daß selbst bei Ausfall des Kugellagers der Diamant nicht mit dem Uhrglas in Berührung kommen kann oder sonstige Teile der Uhr zerstört werden.A securing device according to patent claim 7, preferably when using diamonds as a decorative or decorative element, ensures that even when it is off in the event of the ball bearing, the diamond cannot come into contact with the watch glass or other parts of the watch can be destroyed.

Unter Dekor- oder Schmuckelementen im obigen Sinne versteht man z.B. Email, Diamanten, Ornamente, Verzierungen, oder ähnliches.Decorative or decorative elements in the above sense mean e.g. Enamel, diamonds, ornaments, decorations, or the like.

Im folgenden wird die Erfindung anhand der Zeichnung an einem Ausführungsbeispiel näher erläutert.The invention is explained in more detail below with reference to the drawing using an exemplary embodiment.

Es zeigen:

  • Figur 1: Eine Armbanduhr mit abgenommenem Gehäuseboden im Schnitt.
Show it:
  • Figure 1: A wristwatch with the case back removed on average.

Die Armbanduhr besitzt ein Uhrgehäuse 20, das nach oben durch ein Uhrglas 12 und nach unten durch einen Gehäuseboden 19 begrenzt ist. Im Innern der Uhr befindet sich ein Uhrwerk 22, Zeiger 23,24 mit Zeigerwellen 11,12. Eine Scheibe 15 ist um eine zentrale Achse s-s frei drehbar an einem Kugellager 14 beweglich gelagert angeordnet. Die Scheibe trägt Dekor-und/oder Schmuckelemente. Durch die Nabe 15c der Scheibe 15 sind die Zeigerwellen 10,11 der Zeiger 23,24 hindurchgeführt. Das Uhrwerk 22 ist von einem Werkaufnahmering 17 abgedeckt. Der Werkaufnahmering 17 ist mit dem Kugellager 14 und der das Kugellager 14 abdeckenden drehbaren Scheibe 15 durch Verpressen zusammengefügt. Die Scheibe 15 besitzt zur Entlastung der Kugellager 14 einen mittigen Massenschwerpunkt. Der Werkaufnahmering 17 ist derart mit dem Uhrwerk 22 verbindbar, daß die Innenteile der Uhr nur mit der Scheibe 15 aus der Uhr herausnehmbar sind. Das Uhrwerk 22 ist vom Werkaufnahmering 17, Uhrgehäuse 20 und Gehäuseboden 19 derart umschlossen, daß kein gesondertes Gehäuse für das Uhrwerk 22 erforderlich ist. Das Uhrwerk ist auf seinem ganzen Umfang von einem Werkring 16 umfaßt. Der Werkring 16 besitzt eine eingeformte Ringnut 16a, in die Rastnasen 17a des Werkaufnahmeringes eingreifen. Die Rastnasen 17a sind am äußeren Flansch 17b des Werkaufnahmeringes 17 über dessen gesamten Umfang angeformt. Nach Einbau aller Innenteile und nach Verschließen der Uhr mittels Gehäuseboden 19 liegt der äußere Flansch 17b des Werkaufnahmeringes und damit auch die Rastnasen 17a und die Ringnut 16a derart an einer Wandung 20a des Uhrgehäuses an, daß die Rastung festgelegt ist und daß es nicht möglich ist, das Werk aus der Uhr zu entfernen, ohne gleichzeitig die übrigen Innenteile der Uhr auch aus der Uhr herauszunehmen.The wristwatch has a watch case 20 which is limited at the top by a watch glass 12 and at the bottom by a case bottom 19. Inside the watch there is a clockwork 22, hands 23, 24 with pointer shafts 11, 12. A disk 15 is arranged so as to be freely rotatable about a central axis s-s on a ball bearing 14. The pane carries decorative and / or decorative elements. The pointer shafts 10, 11 of the pointers 23, 24 are passed through the hub 15c of the disk 15. The clockwork 22 is covered by a movement receiving ring 17. The factory mounting ring 17 is joined to the ball bearing 14 and the rotatable disk 15 covering the ball bearing 14 by pressing. The disc 15 has a center of gravity to relieve the ball bearings 14. The movement receiving ring 17 can be connected to the clockwork 22 such that the inner parts of the clock can only be removed from the clock with the disk 15. The clockwork 22 is enclosed by the movement receiving ring 17, the clock case 20 and the case back 19 in such a way that no separate housing is required for the clockwork 22. The entire movement is encompassed by a movement ring 16. The work ring 16 has a molded-in annular groove 16a, into which the locking lugs 17a of the work receiving ring engage. The locking lugs 17a are formed on the outer flange 17b of the work receiving ring 17 over its entire circumference. After all the internal parts have been installed and after the watch has been closed by means of the case base 19, the outer flange 17b of the movement receiving ring, and thus also the latching lugs 17a and the annular groove 16a, bear against a wall 20a of the watch case in such a way that the latching is fixed and that it is not possible to remove the movement from the watch without simultaneously removing the other inner parts of the watch from the watch.

Am Werkring 16 bzw. am Werkaufnahmering 17 sind Stützelemente 18 angeordnet, die sich am Gehäuseboden 19 abstützen. Über diese Stützelemente 18 ist eine Stoßdämpfung des Uhrwerks möglich.Support elements 18, which are supported on the housing base 19, are arranged on the work ring 16 or on the work receiving ring 17. Shock absorption of the clockwork is possible via these support elements 18.

Besonders zu erwähnen ist die Scheibenaufhängung der Scheibe 15. Ein innerer radialer Flansch 17c des Werkaufnahmerings 17 ist mit dem äußeren Kugellagerring 14a und ein innerer radialer Flansch 15a der Scheibe 15 ist mit dem inneren Kugellagerring 14b verbunden. Dadurch ist es möglich, daß auf der sichtbaren Oberfläche der Scheibe keine Kugellagerabdeckung mehr erforderlich ist. Durch das Zentrum der Scheibe treten lediglich noch die Zeigerwellen 10,11 durch die Nabe 15c hindurch. Trotz dieser Ausbildung ist es möglich, eine derart feste Verbindung zwischen Scheibe, Kugellager und Werkaufnahmering zu erreichen, daß diese schwerlich von Hand getrennt werden kann. Der Aufbau dieser Scheibenaufhängung erlaubt zudem die gewünschte flache Bauweise der gesamten Uhr.The disc suspension of the disc 15 should be mentioned in particular. An inner radial flange 17c of the work support ring 17 is connected to the outer ball bearing ring 14a and an inner radial flange 15a of the disc 15 is connected to the inner ball bearing ring 14b. This means that there is no longer any need for a ball bearing cover on the visible surface of the disc. Only the pointer shafts 10, 11 pass through the center of the disk through the hub 15c. Despite this design, it is possible to achieve such a firm connection between the disc, ball bearing and factory mounting ring that it can hardly be separated by hand. The structure of this disc suspension also allows the desired flat design of the entire watch.

Zur Erreichung eines mittigen Schwerpunktes ist die Scheibe 15 in bekannter Weise ausgewuchtet. Ihre Bewegungen erfolgen aufgrund der Körperbewegungen des Trägers der Uhr. Den Antrieb für die Bewegungen bildet dabei die Trägheitskraft der Scheibe.To achieve a central center of gravity, the disk 15 is balanced in a known manner. Their movements are based on the body movements of the wearer of the watch. The drive for the movements is the inertia of the disc.

Als Scheibe kann auch eine wenigstens teilweise durchsichtige Scheibe gewählt werden, die dann die Sicht auf den aus undurchsichtigem Material gebildeten Werkaufnahmering 17 freigibt. Die Scheibe besitzt in den Außenbereichen Verstärkungen 15b, die eine feste Unterbringung der Dekor-und Schmuckelemente erlauben.An at least partially transparent pane can also be selected as the pane, which then releases the view of the work receiving ring 17 formed from opaque material. The pane has reinforcements 15b in the outer areas, which allow the decorative and decorative elements to be securely accommodated.

Zur Sicherung gegen eine Beschädigung z.B. von Zeigern 23,24 oder Uhrglas 12 ist am Uhrgehäuse 20 ein die Ablösung der Scheibe 15 in Richtung auf das Uhrglas 12 verhindernder Rand 20b vorgesehen. Dieser Rand stört bei intakter Aufhängung die Beweglichkeit der Scheibe 15 nicht. Lediglich bei Versagen der Scheibenaufhängung z.B. bei einem Defekt des Kugellagers 14, verhindert dieser Rand 20b, daß sich die Scheibe selbständig macht und durch ihre Bewegung empfindliche Teile der Uhr zerstört.To protect against damage e.g. A pointer 20, 24 or watch glass 12 has an edge 20b on the watch case 20 which prevents the disc 15 from detaching in the direction of the watch glass 12. This edge does not interfere with the mobility of the disc 15 when the suspension is intact. Only if the window suspension fails, e.g. in the event of a defect in the ball bearing 14, this edge 20b prevents the disk from becoming independent and, through its movement, destroying sensitive parts of the watch.

Ein wichtiger Punkt bei der Kosteneinsparung ergibt sich durch die Montage der Uhr. Zunächst wird die Scheibe 15 mit Kugellager 14 und Werkaufnahmering 17 verpreßt. Anschließend wird der das Uhrwerk umgreifende Werkring mit dem Werkaufnahmering über die Rastnasen 17a verbinden, wobei gleichzeitig die Zeigerwellen 10,11 durch die Nabe 15c der Scheibe hindurchgeführt werden. Nach Montage der Zeiger 23,24 werden Scheibe 15, Werkaufnahmering 17, Uhrwerk 22 und Zeiger 23,24 mit all ihren Verbindungsteilen als eine bauliche Montageeinheit in das Uhrgehäuse 20 eingesetzt. Abschließend muß nur noch die Uhr mit dem Gehäuseboden 19 verschlossen werden.An important point in saving costs is the assembly of the watch. First, the disc 15 is pressed with ball bearing 14 and factory mounting ring 17. The movement ring encompassing the movement is then connected to the movement receiving ring via the locking lugs 17a, the pointer shafts 10, 11 being simultaneously passed through the hub 15c of the disk. After the assembly of the pointers 23, 24, the disc 15, the movement support ring 17, the clockwork 22 and the pointers 23, 24 with all their connecting parts are inserted into the watch case 20 as a structural assembly unit. Finally, only the clock has to be closed with the case back 19.
