The circumferential ends (15a) of the clamping ring are retained securely against lateral deflection and guided by a profiled part, matched to the trapezoidal profile of the clamping ring, in the form of an elongate bridging piece (20). The clamping lever (22) is constructed and arranged in such a way that, in the closed position of the closure, it grips over and secures the bridging piece (20) from the outside over its entire length with the ends of the clamping ring (15a, 15b), accommodated therein, with tight profile matching. <IMAGE>

Description

Die Erfindung betrifft einen Spannringverschluß für Behälter aus Blech, wie Eimer, Hobbock oder dgl. mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a clamping ring closure for containers made of sheet metal, such as buckets, hobbock or the like. With the features of the preamble of claim 1.

Derartige behälter mit Spannringen und Spannringverschlüssen sind seit langem all­gemein bekannt. So zeigt das deutsche Gebrauchsmuster 19 90 800 einen Spannring­verschluß, bei dem der Verschluß abweichend von der allgemeinen Krümmung des Spannringes auf seiner Länge geradlinig ausgebildet ist. Dies gilt auch für ein profiliertes Überbrückungsstück, das an dem einen Umfangsende des Spannringes fest angebracht ist und das andere Umfangsende des Spannringes verschieblich auf­nimmt. die beweglichen Elemente des Verschlusses sind so an den Teilen angelenkt, daß sie in einer Ebene beweglich sind, die senkrecht zu der Ebene des Spannringes verläuft. Das Überbrückungsstück weist einen Rastbügel auf, der in ein Fenster am freien Ende des Betätigungshebels des Verschlusses in der Schließstellung eingreift um einVerschwenken des Hebels in Richtung Offenstellung zu verhindern. Es sind auch Spannringverschlüsse bekannt, bei denen die beweglichen Elemente des Verschlusses um Achsen schwenkbar sind, die senkrecht zu der Ebene des Spann­ringes verlaufen, wobei die Elemente der Umfangskrümmung des Spannringes angepaßt sind, sodaß sie satt an der Außenfläche des Spannringes in der Verschluß­stellung des Behälters anliegen (vgl. deutsche GM-Schriften 72 10 719, 75 12 896 oder 76 11 482). Bei den Spannringverschlüssen gemäß den beiden zuerst ge­nannten Gebrauchsmustern sind die Umfangsenden des Spannringes weder in der Offenstellung noch in der Schließstellung noch in irgendeiner dazwischenliegen­den Stellug geführt. Bei dem Verschluß nach dem zuletzt genannten Gebrauchs­muster ist ebenfalls ein profiliertes Uberbrückungsstück vorhanden, in dem in jeder Phase der Verschlußbewegung beide Umfangsenden des Spannringes aufgenommen und geführt sind, wobei das Überbrückungsstück mit dem einen Umfangsende fest verbunden ist. Im Bereich seines anderen Endes weist das Überbrückungsstück einseitig einen über die Längskante vorspringenden Lappen auf, der um die Längskante des beweglichen Umfangsendes des Spannringes zur Bildung einer Führung umgelegt ist. An diesem gleichen Ende des Überbrückungs­stückes ist die Zuglasche angelenkt, während der Spannhebel im Abstand davon am Spannring selbst schwenkbar gelagert ist. In der Schließstellung liegt somit der Spannhebel direkt über dem Spannring in einem Umfangsabstand von dem die Umfangsenden des Spannringes aufnehmenden Überbrückungsstück. Bei diesem bekannten Verschluß sind zwar die Umfangsenden des Spannringes im Überbrückungsstück geführt und gesichert. Diese Sicherung reicht jedoch in vielen Fällen bei der teilweise hohen Beanspruchung des Randes eines solchen Behälters durch Einwirkung äußerer Kräfte oft nicht aus, um ein seitliches Ausweichen der Umfangsenden des Spannringes oder eine Verformung des Überbrückungsstückes auszuschließen. Auch das halbkreisförmige Profil von Spannring und Überbrückungsstück setzt darüber hinaus den möglichen hohen Beanspruchungen des Spannringverschlusses keinen ausreichend hohen Verformungswiderstand entgegen.Such containers with clamping rings and clamping ring closures have long been known. So the German utility model 19 90 800 shows a clamping ring closure, in which the closure is formed in a straight line along its length, deviating from the general curvature of the clamping ring. This also applies to a profiled bridging piece which is fixedly attached to one circumferential end of the clamping ring and slidably receives the other circumferential end of the clamping ring. the movable elements of the closure are articulated on the parts so that they are movable in a plane which is perpendicular to the plane of the clamping ring. The bridging piece has a locking bracket which engages in a window at the free end of the actuating lever of the closure in the closed position in order to prevent the lever from pivoting in the direction of the open position. Clamping ring closures are also known, in which the movable elements of the closure are pivotable about axes which are perpendicular to the plane of the clamping ring, the elements being adapted to the circumferential curvature of the clamping ring so that they fit snugly on the outer surface of the clamping ring in the closed position of the container concerns (see German GM publications 72 10 719, 75 12 896 or 76 11 482). In the tension ring closures according to the two first-mentioned utility models, the circumferential ends of the tension ring are neither in the open position nor in the closed position nor in any position in between. In the closure according to the last-mentioned utility model, there is also a profiled bridging piece in which both circumferential ends of the clamping ring are received and guided in each phase of the closure movement, the bridging piece being firmly connected to one circumferential end. In the area of its other end, the bridging piece has on one side a tab projecting over the longitudinal edge, which is folded around the longitudinal edge of the movable peripheral end of the clamping ring to form a guide. At this same end of the bridging piece, the pull tab is articulated, while the clamping lever is pivotally mounted at a distance from it on the clamping ring itself. In the closed position, the tensioning lever thus lies directly above the tensioning ring at a circumferential distance from the bridging piece receiving the circumferential ends of the tensioning ring. In this known closure, the peripheral ends of the clamping ring are guided and secured in the bridging piece. In many cases, however, this securing is not sufficient when the edge of such a container is subjected to high loads due to the action of external forces in order to rule out lateral deflection of the circumferential ends of the clamping ring or deformation of the bridging piece. In addition, the semicircular profile of the clamping ring and bridging piece does not counter the possible high stresses of the clamping ring closure with a sufficiently high resistance to deformation.

Es ist Aufgabe der Erfindung die aufgezeigten Nachteile zu vermeiden und einen Spannringverschluß mit den Merkmalen des Oberbegriffs des Anspruchs 1 so weiterzubilden, daß besser als bisher gewährleistet ist, daß der Spannring in jeder Phase des Schließ- oder Öffnungsvorganges und auch bei starken äußeren Beanspruchungen seine Kreisform beibehält und Spannring und Verschluß einen gegen die Einwirkung äußerer Kräfte hohen Verformungswiderstand und hohe Festigkeit zeigen und im Verschlußbereich die Umfangsenden des Spannringes zu­verlässig und wie der Verschluß selbst widerstandsfähiger gegen äußere Einwirkungen geschützt sind.It is an object of the invention to avoid the disadvantages shown and to develop a clamping ring closure with the features of the preamble of claim 1 in such a way that it is better ensured than before that the clamping ring in Every phase of the closing or opening process and even with strong external stresses maintains its circular shape and the clamping ring and closure have a high resistance to deformation and high strength against the action of external forces and the circumferential ends of the clamping ring in the closure area are reliably protected and, like the closure itself, are more resistant to external influences are.

Diese Aufgabe wird durch die Lehre des Anspruchs 1 gelöst.This object is achieved by the teaching of claim 1.

Die Umfangsenden des Spannringes sind bei dem Verschluß gemäß der Erfindung nicht nur ständig in dem profilierten Überbrückungsstück aufgenommen, sondern das bewegliche Umfangsende ist stets über seine ganze Eingriffslänge am Über­brückungsstück zuverlässig geführt, so daß während der Betätigung des Ver­schlusses ein seitliches Ausweichen der Umfangsenden des Spannringes nicht zu befürchten ist. Gleichzeitig wird durch diese Ausbildung eine exakte Kreisform des Spannringes zwangsweise aufrechterhalten, wodurch die Betätigung des Ver­schlusses erleichtert wird. Die Formstabilität des Verschlußbereiches wird dabei ganz wesentlich dadurch erhöht, daß in der Schließstellung der dem Profil des Spannringes und Überbrückungsstückes angepaßte Spannhebel die Enden des Spannringes und das Überbrückungsstück auf dessen ganzer Länge an allen freien Seiten zuverlässig übergreift. Damit ist eine zweifache Überlappung und damit eine zweifache Sicherung der Stoßstelle des geschlitzten Spannringes erreicht.The circumferential ends of the tension ring are not only continuously received in the profiled bridging piece in the closure according to the invention, but the movable circumferential end is always reliably guided over its entire engagement length on the bridging piece, so that lateral deflection of the circumferential ends of the tensioning ring does not occur during the actuation of the closure is to be feared. At the same time, an exact circular shape of the clamping ring is forcibly maintained by this design, which facilitates the actuation of the closure. The dimensional stability of the closure area is increased considerably by the fact that in the closed position the clamping lever adapted to the profile of the clamping ring and bridging piece reliably overlaps the ends of the clamping ring and the bridging piece along its entire length on all free sides. This results in a double overlap and thus a double securing of the joint of the slotted clamping ring.

Die Unteransprüche beinhalten vorteilhafte Weiterbildungen des Spannringver­schlusses gemäß der Erfindung.The subclaims contain advantageous developments of the clamping ring closure according to the invention.

Die Erfindung wird nachfolgend anhand schematischer Zeichnungen an einem Ausführungsbeispiel näher erläutert. Es zeigen:

  • Figur 1 den offenen Spannringverschluß gemäß der Erfindung mit Blick in Rich­tung der Verschluß- bzw. Behälterachse.
  • Figur 2 in gleicher Darstellung wie Figur 1 den Verschluß in der Schließstellung.
  • Figur 3 den Verschluß nach Figur 1 und 2 in Draufsicht und
  • Figur 4 im größeren Maßstabe und im Ausschnitt einen senkrechten Schnitt durch den Veschlußbereich entlang der Schnittebene IV-IV der Figur 2.
The invention is explained in more detail below with the aid of schematic drawings using an exemplary embodiment. Show it:
  • Figure 1 shows the open clamping ring closure according to the invention with a view in the direction of the closure or container axis.
  • Figure 2 in the same representation as Figure 1, the closure in the closed position.
  • Figure 3 shows the closure of Figure 1 and 2 in plan view and
  • FIG. 4 on a larger scale and in the detail a vertical section through the closure area along the section plane IV-IV of FIG. 2.

Der Spannringverschluß gemäß der Erfindung ist bestimmt zur Verwendung bei Behältern aus Blech, wie Eimer, Hobbock oder dergleichen. Eine bevorzugte Aus­führungsform eines solches Behälters ist in Figur 4 angedeutet. Der Behälter 1 weist einen Behälterrumpf 8 auf, dessen Randbereich zu einer spiralförmigen Bordierung 9 mit unter Flankenpressung anliegenden Windungsbereichen ausgebil­det und somit versteift ist. Die freie Kante der Bordierung ist bei 14 angedeu­tet. Der Eindrückdeckel 2 weist einen Deckelspielge 3 auf, der über eine Kernwand 4 mit einem kreisbogenförmig nach außen gekrümmten Randflansch 5 verbunden ist. Die Kernwand kann, wie angedeutet, eine Stapelschulter 10 zum Stapeln der Deckel aufweisen. Der äußere Schenkel 6 ist zylindrisch nach unten verlängert und sein Rand ist bei 7 nach außen eingerollt. Die Einrollung 7 und die Bordierung 9 sind so angeordnet, daß ihre Unterkanten in einer gemeinsamen, senkrecht zur Behälterachse verlaufenden Ebene 12 liegen. Dabei weist die Bor­dierung 9 einen wesentlich größeren Durchmesser als die Einrollung 7 des Deckels auf, vorzugsweise ist er mindestens doppelt so groß.The clamping ring closure according to the invention is intended for use in containers made of sheet metal, such as buckets, hobbocks or the like. A preferred embodiment of such a container is indicated in Figure 4. The container 1 has a container fuselage 8, the edge region of which is formed into a spiral border 9 with winding regions lying under flank pressure and is thus stiffened. The free edge of the border is indicated at 14. The press-in cover 2 has a cover play 3 which is connected via a core wall 4 to an edge flange 5 which is curved outward in the shape of a circular arc. The core wall can, as indicated, have a stacking shoulder 10 for stacking the lids. The outer leg 6 is extended cylindrically downwards and its edge is rolled out at 7. The curl 7 and the border 9 are arranged so that their lower edges lie in a common plane 12 running perpendicular to the container axis. The border 9 has a much larger diameter than the curl 7 of the cover, preferably it is at least twice as large.

Der Deckel wird zum Verschließen des Behälters in das Rumpfende eingedrückt, so daß eine ursprünglich O-ringförmige Dichtung 11 den Freiraum zwischen Randflansch 5 und Bordierung 9 ausfüllt, wie dies in Figur 4 gezeigt ist. Die Teile werden in dem fest zusammengepreßten und abgedichteten Zustand durch den Spannring 15 gehalten.The lid is pressed into the end of the fuselage to close the container, so that an originally O-ring-shaped seal 11 fills the space between the edge flange 5 and the flange 9, as shown in FIG. The parts are held in the tightly compressed and sealed state by the clamping ring 15.

Der Spannring 15 weist bevorzugt ein etwa trapezförmiges Querschnittsprofil auf. Sein unterer Schenkel 16 verläuft parallel zu der Ebene 12 und liegt unter Flankenpressung an der Randeinrollung 7 und der Bordierung 9 von Deckel und Rumpf an. Die Innenkante 17 des unteren Schenkels 16 liegt fest an der Rumpf­wand 8 an. Der Spannring 15 schmiegt sich dann unter Flankenpressung mit ent­sprechender Krümmung an die Randeinrollung 7 und die kreisbogenförmige Krümmung des Randflansches 5 an. Die gekrümmten Bereiche werden durch den Bereich 18 des Spannringes miteinander verbunden. Der obere Schenkel 19 ragt schräg nach innen und über die Kernwand 4 des Eindrückdeckels hinaus.The clamping ring 15 preferably has an approximately trapezoidal cross-sectional profile. Its lower leg 16 runs parallel to the plane 12 and lies under flank pressure on the edge curl 7 and the border 9 of the lid and body. The inner edge 17 of the lower leg 16 lies firmly against the fuselage wall 8. The clamping ring 15 then nestles against the edge curl 7 and the arcuate curvature of the edge flange 5 with flank pressure with a corresponding curvature. The curved regions are connected to one another by the region 18 of the clamping ring. The upper leg 19 protrudes obliquely inwards and beyond the core wall 4 of the push-in cover.

Im Verschlußbereich sind die Umfangsenden 15a, 15b des Spannringes 15 nahezu über die ganze Querschnittslänge in dem annähernd trapezförmigen, gleichartigen Profil des Überbrückungsstückes 20 aufgenommen. Der untere Schenkel des Überbrückungsstückes endet etwa in der zur Behälterachse parallelen Mittellinie des Rollrandes, während der obere Schenkel über den Schenkel 19 des Spannringes 15 hinausragt und zur Bildung einer über die ganze Länge des Über­brückungsstückes 20 reichenden Führung 21 nach innen umgelegt ist, die in der ausgezogenen oder in der gestrichelten Form in Fig. 4 ausgeführt sein kann.In the closure area, the peripheral ends 15a, 15b of the clamping ring 15 are accommodated in the approximately trapezoidal, similar profile of the bridging piece 20 over almost the entire cross-sectional length. The lower leg of the bridging piece ends approximately in the center line of the rolled edge parallel to the container axis, while the upper leg protrudes beyond the leg 19 of the clamping ring 15 and to form a guide 21 extending over the entire length of the bridging piece 20, which is folded inwards in the extended or in the dashed form in Fig. 4 can be executed.

In der Schließstellung wird wiederum das Überbrückungsstück 20 auf seiner ganzen Erstreckung und über im wesentlichen die ganze Umfangslänge mit einem gleichartigen trapezförmigen Profil des Spannhebels 22 umfaßt. Damit ergibt sich eine außerordentlich hohe Stabilität im Verschlußbereich.In the closed position, the bridging piece 20 is in turn covered over its entire extent and over substantially the entire circumferential length with a trapezoidal profile of the tensioning lever 22 of the same type. This results in an extraordinarily high stability in the closure area.

Die Figuren 1 bis 3 zeigen den Verschluß in verschiedenen Phasen und verschie­denen Ansichten. Das Überbrückungsstück 20 und der Spannhebel 22 sind der kreisförmigen Krümmung des Spannringes 15 angepaßt. Sie sorgen also auch in dem Unterbrechungsbereich des Spannringes für die exakte Einhaltung der Kreisform des Spannringes. Das Überbrückungsstück 20 ist an dem Umfangsende 15a des Spannringes 15 starr befestigt, z.B. festgeschweißt. An diesem Ende weist das Überbrückungsstück eine außenliegende, in Umfangsrichtung auskragen­de Zunge 29 mit nach außen vorspringendem Hakenelement 30 auf, das in der Schließstellung nach Figur 2 und 3 durch ein Fenster 32 des Spannhebels 22 ragt und den Spannhebel verriegelnd übergreift. Der Verschluß kann nur geöffnet werden, wenn das hakenförmige Ende 30, das im Bereich 31 nach Figur 1 eine Soll-Bruchstelle aufweist, abgebrochen wird. Der Verschluß wirkt so als Garan­tieverschluß. Der Sicherungshaken ist so ausgeführt, daß alle handelsüblichen Plombierungseinrichtungen eingesetzt werden können.Figures 1 to 3 show the closure in different phases and different views. The bridging piece 20 and the clamping lever 22 are adapted to the circular curvature of the clamping ring 15. They also ensure that the circular shape of the clamping ring is maintained precisely in the interruption area of the clamping ring. The bridging piece 20 is rigidly attached to the peripheral end 15a of the clamping ring 15, e.g. welded. At this end, the bridging piece has an outer, circumferentially projecting tongue 29 with an outwardly projecting hook element 30, which in the closed position according to FIGS. 2 and 3 projects through a window 32 of the tensioning lever 22 and overlaps the tensioning lever in a locking manner. The closure can only be opened if the hook-shaped end 30, which has a predetermined breaking point in the area 31 according to FIG. 1, is broken off. The closure thus acts as a guarantee closure. The safety hook is designed so that all commercially available sealing devices can be used.

Am anderen Ende des Überbrückungsstückes 20 sind aus diesem Lappen ausgeformt, durch die ein nietförmiger Schwenkzapfen 25 ragt, an dem der Spannhebel 22 mit Hilfe aus dem Spannhebel ausgeformten Lappen schwenkbar gelagert ist. Aus dem Spannhebel 22 sind weiter Lappen für einen nietförmigen Zapfen 28 herausgeformt, an dem das eine Ende der z.B. als Blattfeder ausgebil­deten Spannzunge 26 verankert ist. Das andere Ende der Spannzunge oder Spann­lasche ist am Umfang des Spannringes 15 bei 27 befestigt, z.B. durch Punktschweißen.At the other end of the bridging piece 20 are formed from this tab, through which a rivet-shaped pivot pin 25 projects, on which the tensioning lever 22 is pivotally supported by means of tabs formed from the tensioning lever. Flaps for a rivet-shaped pin 28 are formed out of the tensioning lever 22, on which one end of the e.g. is designed as a leaf spring clamping tongue 26 is anchored. The other end of the clamping tongue or lug is attached to the circumference of the clamping ring 15 at 27, e.g. by spot welding.

Die Funktion des Spannverschlusses ist aus den Figuren 1 bis 3 und der vorherge­henden Beschreibung ohne weiteres ersichtlich. Aus Figur 2 erkennt man, daß der Spannhebel 22 das Überbrückungsstück 20 und die darin aufgenommenen Enden 15a, 15b des Spannringes 15 über mindestens die ganze Länge des Über­brückungsstückes 20 von außen sicher umgreift, wie dies anhand der Figur 4 bereits erläutert ist.The function of the turnbuckle is readily apparent from Figures 1 to 3 and the preceding description. It can be seen from FIG. 2 that the tensioning lever 22 securely grips the bridging piece 20 and the ends 15a, 15b of the tensioning ring 15 accommodated therein from the outside over at least the entire length of the bridging piece 20, as has already been explained with reference to FIG.
