Description

Die Erfindung bezieht sich auf eine Armbanduhr gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a wristwatch according to the preamble of claim 1.

Eine derartige Armbanduhr ist aus der CH-B-624 535 bekannt. Hierbei ist der aus einem elastisch verformbaren Kunststoff bestehende Werkhaltering ziemlich kompliziert gestaltet. Er ist derart gestuft ausgebildet, dass sein unterer Abschnitt gegenüber seinem oberen Abschnitt radial nach aussen versetzt ist und in einer entsprechenden Ausdrehung im unteren Bereich des Mittelteils sitzt, wobei die aneinanderliegenden Flächen der Ausdrehung und des Umfangs des unteren Abschnitts des Werkhalterings kegelstumpfförmig gestaltet sind. Der sich zwischen oberem und unterem Abschnitt radial erstreckende Abschnitt des Werkhalterings liegt mit seiner Oberseite an der die erwähnte Ausdrehung begrenzenden radialen Ringschulter des Mittelteils und mit seiner Unterseite auf dem oberen Rand des nach innen gerichteten, ringförmigen Vorsprungs des Bodens. Es ist also nur dieser die Stufe bildende, sich radial erstreckende Abschnitt des Werkhalterings, welcher beim Eindrücken des Bodens komprimiert wird, da der radial nach aussen über den ringförmigen Vorsprung des Bodens hinrausragende Bodenrand die Unterseite des Werkhalterings im montierten Zustand der Uhr nicht berührt. Da ausserdem die oberen und unteren Anlagestellen für den radialen Abschnitt des Werkhalterings, das heisst die Ringschulter des Mittelteils und der obere Rand des ringförmigen Vorsprungs des Bodens, nicht vertikal übereinanderliegen, sondern radial versetzt sind, erfährt das durch den Boden komprimierte Material des Werkhalterings eine Scherdeformation, deren Stärke von der Kraft abhängt, mit welcher der Boden eingedrückt wird. Zur Halterung des Uhrwerks greift eine an diesem vorgesehene, radial vorstehende Leiste in eine Ringnut am Innenumfang des oberen Abschnitt des Werkhalterings ein. Das Zifferblatt, dessen Unterseite sich im grösseren Abstand vom oberen Rand des Werkhalterings befindet, wird lediglich durch das Uhrwerk, auf dem es befestigt ist, gehalten.Such a wristwatch is known from CH-B-624 535. Here, the movement retaining ring consisting of an elastically deformable plastic is designed to be quite complicated. It is designed so that its lower section is offset radially outwards from its upper section and sits in a corresponding recess in the lower region of the middle part, the abutting surfaces of the recess and the circumference of the lower section of the movement retaining ring being frustoconical. The section of the movement retaining ring which extends radially between the upper and lower sections lies with its upper side on the radial annular shoulder of the central part which limits the aforementioned rotation and with its lower side on the upper edge of the inwardly directed, annular projection of the base. It is therefore only this radially extending section of the movement retaining ring that forms the step, which is compressed when the base is pressed in, since the base edge protruding radially outward beyond the annular projection of the base does not touch the underside of the movement retaining ring when the watch is in the assembled state. In addition, since the upper and lower contact points for the radial section of the movement holding ring, i.e. the ring shoulder of the middle part and the upper edge of the ring-shaped projection of the base, are not vertically one above the other but are radially offset, the material of the movement holding ring compressed by the base undergoes shear deformation whose strength depends on the force with which the soil is pressed in. To hold the clockwork, a radially protruding bar provided thereon engages in an annular groove on the inner circumference of the upper section of the movement retaining ring. The dial, the underside of which is at a greater distance from the upper edge of the movement retaining ring, is only held by the movement on which it is attached.

Durch die CH-B-657 957 ist ein Uhrgehäuse mit einem metallischen Werkhaltering bekannt, der auf dem oberen Rand eines an der Innenfläche des Bodens angeformten ringförmigen Vorsprungs aufliegt und dessen Oberseite eine Auflage für den Zifferblattrand bildet, welcher von einem am Innenumfang des Mittelteils angeformten Ringvorsprung übergriffen wird. Hierbei liegt die Oberseite des Werkhalterings nicht an einer Ringschulter des Mittelteils an, und alle zusammenwirkenden Einzelteile müssen so bemessen sein, dass der Zifferblattrand nach der Montage des Bodens, welcher durch Schrauben befestigt wird, spielfrei, jedoch ohne Verformung infolge zu starker Pressung, gehalten wird.From CH-B-657 957 a watch case is known with a metallic movement retaining ring, which rests on the upper edge of an annular projection formed on the inner surface of the bottom and the upper side of which forms a support for the dial edge, which is formed by one on the inner circumference of the central part Ring projection is overlapped. Here, the top of the movement holder ring does not lie on an annular shoulder of the middle part, and all interacting individual parts must be dimensioned so that the dial edge is kept free of play after assembly of the base, which is fastened by screws, but without deformation due to excessive pressure .

Der Erfindung liegt die Aufgabe zugrunde, eine Armbanduhr der im Oberbegriff des Anspruchs 1 beschriebenen Art im Aufbau zu vereinfachen und so auszubilden, dass das Gehäuse leicht aus seinen Einzelteilen zusammengesetzt werden kann und dass ein besonderer Dichtungsring zwischen Mittelteil und Boden entfällt.The invention has for its object to simplify the construction of a wristwatch of the type described in the preamble of claim 1 and to design it in such a way that the housing can easily be assembled from its individual parts and that a special sealing ring between the middle part and the bottom is omitted.

Diese Aufgabe wird erfindungsgemäss durch die im Patentanspruch 1 angegebenen Merkmale gelöst.
Der wesentliche Vorteil der Armbanduhr nach der Erfindung besteht darin, dass nicht nur Mittelteil und Boden des Gehäuses unter Einsparung eines getrennten Dichtungsrings einfach unter Zuhilfenahme des Ringflansches des aus Kunststoff bestehenden Werkhalterings dicht miteinander verbunden sind, sondern dass dieser Werkhaltering gleichzeitig auch als Auflage für den Zifferblattrand dient und auf diese Weise die Lage des Zifferblattes fixiert, wenn der Boden durch Eindrücken in den Mittelteil montiert wird. Da die radiale Ringschulter am Innenumfang des Mittelteils in Höhe des oberen Randes des Werkhalterings angebracht ist und daher diese Ringschulter, und nicht das Zifferblatt selber, den oberen Anschlag für den Werkhaltering bildet, wird beim Andrücken des Bodens der Werkhaltering zwischen dem äusseren Rand des Bodens und dem erwähnten Ringvorsprung, und nicht zwischen dem Boden und dem Zifferblatt, komprimiert, so dass eine ungewollte Einquetschung des Zifferblattrandes vermieden wird.According to the invention, this object is achieved by the features specified in patent claim 1.
The main advantage of the wristwatch according to the invention is that not only the middle part and the bottom of the case are tightly connected to one another, without the need for a separate sealing ring, simply with the aid of the ring flange of the plastic retaining ring, but also that this retaining ring also serves as a support for the dial edge serves and in this way fixes the position of the dial when the bottom is installed by pressing into the middle part. Since the radial ring shoulder is attached to the inner circumference of the middle part at the level of the upper edge of the movement holder ring and therefore this ring shoulder, and not the dial itself, forms the upper stop for the movement holder ring, the movement holder ring is pressed between the outer edge of the base and when pressing the bottom the aforementioned ring projection, and not between the bottom and the dial, compressed, so that an unwanted crushing of the dial edge is avoided.

Aus der FR-A-2 019 019 ist eine Kleinuhr ohne Werkhaltering bekannt, bei welcher das mit Uhrglas und Uhrwerk versehene Gehäuse eine vorgefertigte Baueinheit ohne Bandanschlüsse bildet und ein mit Bandanschlüssen versehener Aussenring vorgesehen ist, in den das Gehäuse von unten eingeschoben werden kann. Aussenring und Gehäuse sind lösbar durch einen elastischen Ring miteinander verbunden, der im montierten Zustand in zwei einander gegenüberliegenden Nuten auf dem Aussen-Umfang des Gehäuses und auf dem Innenumfang des Aussen-rings sitzt.From FR-A-2 019 019 a small watch without a movement retaining ring is known, in which the housing provided with watch glass and clockwork forms a prefabricated unit without band connections and an outer ring provided with band connections is provided, into which the housing can be inserted from below. The outer ring and the housing are detachably connected to one another by an elastic ring which, in the assembled state, is seated in two mutually opposite grooves on the outer circumference of the housing and on the inner circumference of the outer ring.

Gemäss einer Ausführungsform der vorliegenden Erfindung ist die durch den Patentanspruch 1 gekennzeichnete Armbanduhr mit einem derartigen, an sich bekannten lösbaren Aussenring versehen, wobei jedoch gemäss Anspruch 2 der elastisch komprimierbare Ring nur in einer einzigen Ringnut sitzt, die auf dem Aussenumfang des Mittelteils angebracht ist, wodurch das Aufschieben des Aussenrings auf das Gehäuse bzw. das Abnehmen des Aussenrings vom Gehäuse erleichtert wird.According to one embodiment of the present invention, the wristwatch characterized by claim 1 is provided with such a detachable outer ring which is known per se, but according to claim 2 the elastically compressible ring is seated only in a single annular groove which is provided on the outer circumference of the central part, whereby the pushing of the outer ring onto the housing or the removal of the outer ring from the housing is facilitated.

Auf diese Weise kann ein Vollständig vorgefertigtes Gehäuse ohne grossen Kraftaufwand in einen nach Wunsch des Kunden zu wählenden Aussenring eingesetzt und aus diesem entfernt werden; so lässt sich insbesondere auch ein Reparaturdienst direkt an der Verkaufsstelle durchführen, indem einfach das Gehäuse mit dem defekten Uhrwerk unter Beibehaltung desselben Aussenrings durch ein neues vorgefertigtes Gehäuse ersetzt wird.In this way, a completely prefabricated housing can be inserted into and removed from an outer ring to be selected by the customer without great effort; in particular, this is also possible carry out a repair service directly at the point of sale by simply replacing the housing with the defective clockwork with the same outer ring and a new prefabricated housing.

Die Erfindung wird anhand der Zeichnung an einem Ausführungsbeispiel näher erläutert. Es zeigen:

  • Figur 1 einen Schnitt der Hälfte einer Armbanduhr in der senkrecht zum Zeigerstellrohr orientierten Ebene, und
  • Figur 2 einen Schnitt der Ausführungsform nach Figur 1 in der Ebene, in welcher das Zeigerstellrohr liegt.
The invention is explained in more detail with reference to the drawing using an exemplary embodiment. Show it:
  • 1 shows a section of half of a wristwatch in the plane oriented perpendicular to the pointer setting tube, and
  • Figure 2 shows a section of the embodiment of Figure 1 in the plane in which the pointer control tube lies.

Nach den Figuren 1 und 2 besteht die Armbanduhr aus einem dichten Gehäuse 1, das aus einem Mittelteil 2 und einem Boden 3 zusammengesetzt und an seiner Oberseite durch ein Uhrglas 4 verschlossen ist, und aus einem Aussenring 5, der ein äusseres Gehäusemittelteil mit angeformten Bandanschlüssen 6 bildet. In das Gehäuse 1 ist ein das Uhrwerk 8 tragender Werkhaltering 7 eingesetzt, welcher aus einem etwa elastisch nachgiebigem Kunststoff besteht und am Innenumfang eine Ringschulter 10 hat, auf der sich das Uhrwerk 8 mit seinem oberen Flansch abstützt. Das Zifferblatt 9 liegt auf der Oberseite des Uhrwerks 8 und des Werkhalterings 7 auf.According to FIGS. 1 and 2, the wristwatch consists of a sealed housing 1, which is composed of a middle part 2 and a base 3 and is closed on its top by a watch glass 4, and an outer ring 5, which has an outer middle part with molded band connectors 6 forms. In the housing 1, a movement holding ring 7 is inserted, which consists of an approximately resilient plastic and has an annular shoulder 10 on the inner circumference, on which the movement 8 is supported with its upper flange. The dial 9 rests on the top of the clockwork 8 and the movement retaining ring 7.

Der Werkhaltering 7 weist an seinem Rande einen angeformten, axial nach unten gerichteten Ringflansch 11 auf, der als Halteelement und Dichtung für den Boden 3 dient. Zu diesem Zwecke hat der Boden 3 auf seiner Innenfläche einen angeformten ringförmigen Vorsprung 13. Der Ringflansch 11 wird zwischen dem Aussenumfang dieses Vorsprungs 13 und dem Innenumfang des Mittelteils 2 eingeklemmt, wobei er aufgrund seines etwas elastischen Kunststoffmaterials komprimiert wird und so eine dichte Presspassung für den Boden 3 bildet.The plant retaining ring 7 has on its edge a molded, axially downwardly directed ring flange 11, which serves as a holding element and seal for the base 3. For this purpose, the bottom 3 has an integrally formed annular projection 13. The ring flange 11 is clamped between the outer circumference of this projection 13 and the inner circumference of the middle part 2, whereby it is compressed due to its somewhat elastic plastic material and thus a tight press fit for the Bottom 3 forms.

Der Boden 3 hat einen den ringförmigen Vorsprung 13 radial nach aussen überragenden Rand 14, der den Ringflansch 11 und wenigstens einen Teil der Unterseite des Mittelteils 2 übergreift. Eine am Bodenrand 14 vorgesehene Kerbe 15 dient zum Einführen eines Werkzeugs, um den Boden 3 vom Mittelteil 2 zu lösen.The bottom 3 has an edge 14 which projects radially outward from the annular projection 13 and which engages over the annular flange 11 and at least part of the underside of the middle part 2. A notch 15 provided on the bottom edge 14 serves to insert a tool in order to detach the bottom 3 from the middle part 2.

Der am Mittelteil 2 anliegende Werkhaltering 7 stösst mit seinem oberen Rand an eine am Innenumfang des Mittelteils 2 vorgesehene Ringschulter 12, so dass er axial zwischen dieser Ringschulter 12 und dem Rand 14 des Bodens 3 fixiert ist. Ein von einem oberen konischen Randabschnitt 16 gebildeter Ringvorsprung 17 am Innenumfang des Mittelteils 2 übergreift den Rand des Zifferblatts 9 und fixiert auf diese Weise dessen Lage. Das Uhrglas 4 ist unter Zwischenlage eines Dichtungsrings 18 in eine am oberen Rand des Mittelteils 2 angebrachte Ausdrehung 19 eingepresst und hat eine die axiale Höhe der Ausdrehung 19 bzw. des Dichtungsringes 18 um etwa das Doppelte übersteigende Dicke.The work holding ring 7 resting on the middle part 2 abuts with its upper edge against an annular shoulder 12 provided on the inner circumference of the middle part 2, so that it is fixed axially between this annular shoulder 12 and the edge 14 of the base 3. An annular projection 17 formed by an upper conical edge section 16 on the inner circumference of the middle part 2 engages over the edge of the dial 9 and in this way fixes its position. The watch glass 4 is pressed with the interposition of a sealing ring 18 into a recess 19 attached to the upper edge of the middle part 2 and has a thickness which exceeds the axial height of the recess 19 or the sealing ring 18 by approximately twice.

Das beschriebene Gehäuse 1 ist einfach aufgebaut und durch den das Glas 4 haltenden Dichtungsring 18 einerseits und den zum Werkhaltering 7 gehörenden Ringflansch 11 andererseits, dessen Kunststoffmaterial eine gewisse Elastizität aufweist, wasserdicht verschlossen, wobei ein besonderer Dichtungsring für den Boden 3 entfällt. Beim Zusammenbau des Gehäuses 1 wird das Glas 4 von oben in die mit dem Dichtungsring 18 versehene Ausdrehung 19 des Mittelteils 2 eingepresst, während das Zifferblatt 9, das Uhrwerk 8 sowie der Werkhaltering 7 von unten in das Mittelteil 2 eingelegt werden und dann der Boden 3 eingepresst wird. Das Rohr 27 für die Zeigerstellwelle, die in Figur 2 nur durch ihre strichpunktierte Mittelachse angedeutet ist, durchsetzt eine Oeffnung 24 im Mittelteil 2 und ragt mit seinem inneren Ende in eine entsprechende Oeffnung 23 im Werkhaltering 7.The housing 1 described has a simple construction and is sealed watertight by the sealing ring 18 holding the glass 4 on the one hand and the ring flange 11 belonging to the work retaining ring 7, the plastic material of which has a certain elasticity, a special sealing ring for the bottom 3 being omitted. When the housing 1 is assembled, the glass 4 is pressed from above into the recess 19 of the middle part 2 provided with the sealing ring 18, while the dial 9, the movement 8 and the movement retaining ring 7 are inserted into the middle part 2 from below and then the bottom 3 is pressed. The pipe 27 for the pointer adjusting shaft, which is indicated in FIG. 2 only by its dash-dotted central axis, passes through an opening 24 in the central part 2 and projects with its inner end into a corresponding opening 23 in the movement holding ring 7.

Eine Armbanduhr nach der Erfindung kann lediglich aus dem vorstehend beschriebenen, dichten Gehäuse 1 bestehen, wobei in diesem Falle am Mittelteil 2 übliche Bandanschlüsse angeformt oder befestigt sind.A wristwatch according to the invention can only consist of the above-described, sealed housing 1, in which case the usual band connections are formed or attached to the middle part 2.

Gemäss der in den Figuren gezeigten besonderen Ausführungsform kann jedoch eine Armbanduhr nach der Erfindung auch einerseits aus dem vorstehend beschriebenen Gehäuse 1, das eine vorgefertigte Baueinheit bildet, und aus dem mit Bandanschlüssen 6 versehenen Aussenring 5 bestehen. Bei dieser Ausführungsform kann das vorgefertigte Gehäuse 1 nach Wunsch mit einem Aussenring 5 beliebigen Aussehens kombiniert werden, indem es einfach von unten in den Aussenring 5 eingeschoben wird, der eine nach unten offene Ausnehmung 25 für das Rohr 27 der Zeigerstellwelle hat, auf der die strichpunktiert angedeutete Krone 26 sitzt.According to the particular embodiment shown in the figures, however, a wristwatch according to the invention can also consist on the one hand of the housing 1 described above, which forms a prefabricated structural unit, and of the outer ring 5 provided with band connections 6. In this embodiment, the prefabricated housing 1 can be combined as desired with an outer ring 5 of any appearance, simply by inserting it from below into the outer ring 5, which has a downwardly open recess 25 for the tube 27 of the pointer actuating shaft, on which the dot-dash line is shown indicated crown 26 sits.

Zur axialen Befestigung des Gehäuses 1 im Aussenring 5 dient ein Ring 20 aus elastischem Material, vorzugsweise ein O-Ring, wie er als Dichtungsring benutzt wird. Dieser Ring 20 sitzt in einer im Aussenumfang des Mittelteils 2 angebrachten Ringnut 21 und hat eine radiale Dicke, die um so viel grösser als die Tiefe der Ringnut 21 ist, dass er im montierten Zustand der Uhr hinreichend komprimiert ist.A ring 20 made of elastic material, preferably an O-ring, such as is used as a sealing ring, is used for axially fastening the housing 1 in the outer ring 5. This ring 20 is seated in an annular groove 21 provided in the outer circumference of the middle part 2 and has a radial thickness which is so much greater than the depth of the annular groove 21 that it is adequately compressed in the assembled state of the watch.

Im betrachteten Beispiel hat die Ringnut 21 einen rechteckförmigen Querschnitt. Zwischen Mittelteil 2 und Aussenring 5 besteht ein kleiner Zwischenraum. Da der Innenumfang des Aussenrings 5 keine Nut hat und glatt ist, benötigt man zum Herausdrücken des Gehäuses 1 aus dem Aussenring 5 eine kleinere Kraft, als wenn der Ring 20 auch mit seinem äusseren Bereich in einer Nut des Aussenrings sässe, aus der er herausgequetscht werden müsste.In the example considered, the annular groove 21 has a rectangular cross section. There is a small space between the middle part 2 and the outer ring 5. Since the inner circumference of the outer ring 5 has no groove and is smooth, a smaller force is required to push the housing 1 out of the outer ring 5 than if the ring 20 were also seated with its outer region in a groove of the outer ring from which it was squeezed out should.
