Description
Wasserdichtes Uhrgehäuse. Das wasserdichte Uhrgehäuse nach der Erfindung weist ein aus elastischem Material angefertigtes Glas auf, das in einer gerbe des Gehäusemittelteils eingesetzt ist.
Der Gehäuseboden ist vermittels Nut und Feder mit dem Gehäusemittelteil verbinden. Es ist auf diese Weise möglich, für unbe dingte Dichtigkeit zu sorgen, denn die Feder kann sehr genau der Nut angepasst .werden. Gegebenenfalls kann sogar die Nut etwas tie- fer als absolut notwendig gemacht werden und eine Packung enthalten, welche einen jeden Wasserdurchgang ausschliesst.
Die Zeichnung zeigt beispielsweise im Schnitt ein wasserdichtes Uhrgehäuse nach der Erfindung.
Der Gehäusemittelteil ist mit 1 bezeich net. Das elastische Glas 2 ist in einer gerbe 3 dieses Gehäusemittelteils auf bekannte Weise mit etwas Spannung eingelassen. Diese Spannung und der gewöhnlich zum Haftenlassen des Glases in der gerbe ange wendete Kitt sorgen hier für die Dichtigkeit.
Der Boden 4 des Gehäuses ist abnehmbar und wird, nach Einführen des Werkes in das Gehäuse, durch eine als Ring auf dem Ge häuseboden gedrehte Feder 5, welche in eine in dem Gehäusemittelteil eingedrehte Nut 6 greift, gehalten. Diese Nut-und-Feder-Verbin- dung kann sehr genau passend gemacht wer den und jede Sicherheit bieten zur Verhin derung des Wasserdurchlasses.
Nichtsdesto weniger kann in der etwas tiefer geschnitte- nen Nut, wie links in der Figur dargestellt ist, eine Packung 8 vorgesehen werden, welche den Eintritt des Wassers unbedingt verhindert.
Es sind Mittel vorgesehen, welche gestat ten, zur Trennung der beiden Teile vermit tels eines Werkzeuges zwischen Boden und Gehäusemittelteil zu greifen.
Waterproof watch case. The waterproof watch case according to the invention has a made of elastic material glass, which is used in a gerbe of the case middle part.
The housing base is connected to the middle part of the housing by means of a tongue and groove. In this way, it is possible to ensure absolute tightness, because the tongue can be adapted very precisely to the groove. If necessary, the groove can even be made somewhat deeper than absolutely necessary and contain a packing which excludes any passage of water.
The drawing shows, for example, in section a waterproof watch case according to the invention.
The middle part of the housing is denoted by 1. The elastic glass 2 is embedded in a gerbe 3 of this middle part of the housing in a known manner with some tension. This tension and the putty usually used to allow the glass to adhere to the tan ensure the tightness here.
The bottom 4 of the housing is removable and, after the movement has been inserted into the housing, is held by a spring 5 rotated as a ring on the housing bottom, which engages in a groove 6 screwed into the housing middle part. This tongue-and-groove connection can be made to fit very precisely and offer every security to prevent water from passing through.
Nevertheless, a packing 8 can be provided in the slightly deeper cut groove, as shown on the left in the figure, which absolutely prevents the entry of the water.
Means are provided which gestat th to grab to the separation of the two parts by means of a tool between the bottom and the housing middle part.
