Title
(DE) KUNSTSTOFFSCHALE FÜR EINE ELEKTRONISCHE ARMBANDUHR
(EN) PLASTIC SHELL FOR AN ELECTRONIC WRISTWATCH
(FR) COQUE EN PLASTIQUE POUR BRACELET-MONTRE ELECTRONIQUE
Abstract
(DE)
Die Kunststoffschale besitzt in ihrem Gehäuseboden (14) eine konische Öffnung (15), die zum Auswechseln der Batterie dient. Zum dichten Verschliessen dieser Öffnung (15) wird ein armiertes Verschlussstück (1) aus flexiblem, elastischem Kunststoff verwendet, das in seinem Zentrum einen axial angegossenen Kegelstumpf (3) aufweist. Der Kegelstumpf (3) dient zur Aufnahme und zur axialen Sicherung eines Chromstahlringes (4). Bei Temperaturänderungen gewährleistet der Chromstahlring (4) die Formbeständigkeit des armierten Verschlussstückes (1) am Pressitz (13).
(EN)
A plastic shell has in its bottom (14) a conical opening (15) for exchanging the battery. For sealing this opening (15), an armed closure piece (1) made of a flexible, elastic plastic is used, having at its center an axially cast truncated cone (3). The truncated cone (3) receives and secures in the axial direction a chrome steel ring (4). The chrome steel ring (4) ensures the dimensional stability of the armed closure piece (1) in the pressure contact zone (13).
(FR)
Une coque en plastique est pourvue, dans son fond (14), d'une ouverture conique (15) pour le remplacement de la pile. Pour fermer cette ouverture (15), on utilise un élément de fermeture armé (1) en matière plastique souple, élastique, qui présente en son centre un cône tronqué (3) moulé axialement. Le cône tronqué (3) sert à loger et à retenir dans le sens axial une bague d'acier chromé (4) qui assure la stabilité dimensionnnelle de l'élément de fermeture armé (1) dans la zone de pression (13).
