Abstract (en)

An open tension ring (3) with a fixing section (5,7) at each end encloses two ring-shaped clamping jaws (11) which fit with their outer contour (12) against the ring and form a circular ring opening with their inner face (19). At least one spring-like member (15) is set between the clamping jaws to drive these apart and hold them secure in the ring. A tension member with at least two engagement sections engage against the fixing sections and tension the open ring to reduce its diameter. INdependent claims describe method for mounting and an arrangement where the fixing member is inside the clamping jaws to form a ring opening.

Abstract (de)

Für das Anordnen bzw. Spannen oder Schrumpfen eines ringförmigen Festhalteorganes wird eine Vorrichtung vorgeschlagen, welche mindestens die folgenden Elemente aufweist: Einen offenen Spannring (3) mit je endständig einem Festhalteabschnit (5, 7), mindestens zwei, innerhalb des Spannringes angeordnete, ringartig gebogene, weitgehendst seitlich aneinanderstossende Klemmbacken (11), welche mit ihrer äusseren Kontur (12) am Spannring anliegen und welche mit ihrer inneren Oberfläche (19) insgesamt wenigstens nahezu eine kreisrunde Öffnung bilden. Weiter weist die Vorrichtung je mindestens ein federartiges Organ (15) zwischen je den seitlich aneinanderstossenden Klemmbacken auf, um diese voneinanderzutreiben bzw. den Spannring im nicht-gespannten Zustand in Ringöffnungs-Durchmesser-vergrössender Richtung auseinanderzutreiben und die Klemmbacken fest im Spannring zu halten. Mittels eines Spannorgans mit mindestens zwei Eingriffabschnitten, vorgesehen, um an den Festhalteabschnitten einzugreifen, kann der offene Spannring in Durchmesser-verkleinernder Richtung gespannt werden. <IMAGE>
