Description

Es ist bereits vorgeschlagen worden, nachgiebige, druckdichte Verbindungen in Form eines Metallschlauches aus im Querschnitt U-förmigen Ringelementen, die an den Enden ihrer freien Schenkel miteinander verbunden sind, zu bilden.It has already been proposed to form compliant, pressure-tight joints a metal hose made of ring elements with a U-shaped cross-section, which at the ends their free legs are interconnected to form.

Diese bekannten Einrichtungen werden nach der Erfindung dadurch verbessert, daß die Außenflächen der Ringscheiben der einzelnen U-förmigen Ringelemente in der Mitte verstärkt und an den Wurzelenden verjüngt sind, während'die inneren Flächen eben verbleiben. Hierdurch wird gegenüber den bekannten Anordnungen der Vorteil erzielt, daß ein unmittelbares Aufeinanderabstützen der einzelnen Scheiben im zusammengedrückten Zustande der Verbindung eintritt, ohne daß ein völliges Zusammenlegen verhindert würde. Außerdem tritt eine besonders zweckmäßigeThese known devices are improved according to the invention in that the outer surfaces of the ring disks of the individual U-shaped ring elements in the middle are reinforced and tapered at the root ends, while the inner surfaces remain flat. This has the advantage over the known arrangements that a direct support of the individual disks occurs in the compressed state of the connection without a complete collapse would be prevented. In addition, a particularly expedient occurs

so Materialverteilung innerhalb jeder einzelnen Scheibe, also innerhalb jedes Schenkels der U-förmigen Ringelemente, ein, wodurch eine größere'Festigkeit ohne Beeinträchtigung der Elastizität und Erhöhung des Gewichts erreicht wird. Durch die ebene Ausbildung der inneren Flächen der U-förmigen Ringelemente ergibt sich trotz Beibehaltung der günstigen, in der Mitte verstärkten Form eine einfachere Bearbeitung. Diese ebene Ausgestaltung wird insbesondere dadurch ermöglicht, daß die nachträglich hergestellte Verbindungsstelle, beispielsweise Schweißstelle, zwischen zwei benachbarten U-förmigen Ringelementen liegt, jedoch nicht zwischen den beiden Schenkeln dieser Ringelemente, zwischen denen ein unmittelbarer Materialzusammenhang besteht.so material distribution within each individual disc, i.e. within each leg of the U-shaped ring elements, creating a greater 'strength without affecting the Elasticity and increase in weight is achieved. Due to the level training of the inner surfaces of the U-shaped ring elements result despite retention of the favorable, in the middle reinforced form for easier machining. This flat design will in particular made possible by the fact that the subsequently produced connection point, e.g. welding point between two adjacent U-shaped ring elements, but not between the two legs of these ring elements, between which a direct one There is a material connection.

In der Zeichnung ist die Erfindung beispielsweise veranschaulicht, und zwar zeigt Abb. ι einen Schnitt durch einen Teil einer.In the drawing, the invention is illustrated by way of example, namely shows Fig. Ι a section through part of a.

druckdichten Verbindung, Abb. 2 einen ein Einzelelement der Verbindung darstellenden, im Querschnitt U-förmigen Ring, Abb. 3 die Verbindung nach Abb. 1 in zusammengedrücktem Zustande.pressure-tight connection, Fig. 2 shows a single element of the connection, in cross-section U-shaped ring, Fig. 3 the connection according to Fig. 1 in compressed Conditions.

In der Zeichnung sind α im Querschnitt *5 U-förmige· Ringe, die zur Bildung der nachgiebigen, druckdichten Verbindung zusammengefügt und durch Schweißen bei b miteinander verbunden sind.In the drawing, α in cross section * 5 are U-shaped rings which are joined together to form the flexible, pressure-tight connection and connected to one another by welding at b.

Die nach außen zu liegenden Flächen der die Schenkel der Ringe ar bildenden Scheiben c sind derart bearbeitet, daß sie in der Mitte eine ringförmige Verstärkung d erhalten, während der Querschnitt an den Wurzeln bei e verjüngt ist.The outwardly facing surfaces of the disks c forming the legs of the rings ar are machined in such a way that they receive an annular reinforcement d in the center, while the cross-section is tapered at the roots at e.

Die Bearbeitung läßt sich mit einfachen Mitteln erreichen, da sie nur an den nach außen zu liegenden Flächen der Ringe α stattfindet, während die nach innen zu liegenden Wandungen/ eben bleiben.The machining can be achieved with simple means, since it only takes place on the surfaces of the rings α facing outwards, while the walls / walls facing inwards remain flat.

Beim Zusammendrücken der Verbindung legen sich die nach dem Scheibenmittelpunkt zu liegenden abgeschrägten Flächen g, wie in Abb. 3 dargestellt, gegeneinander und verhindern hierdurch ein übermäßiges Zusammendrücken der Verbindung und schützen die Scheiben vor Überbeanspruchungen. When the connection is pressed together, the inclined surfaces g, which are to be located towards the center of the pane, lie against one another, as shown in Fig. 3, and thereby prevent the connection from being excessively compressed and protect the panes from overstressing.
