PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist eine Einrichtung an fernrohrartig ineinander geschobenen Metallrohren, wie sie vielfach angewendet werden, z. B. als verstellbarer Stiel bei hauswirtschaftlichen Geräten, und bezweckt, eine schraubenlose Feststellung der einzelnen Rohre in der jeweils gewünschten Lage zu ermöglichen. Die Zeichnung stellt ein Ausführungsbeispiel dar, und zwar istThe subject of the invention is a device to telescope-like nested Metal pipes, as they are often used, z. B. as an adjustable handle for domestic use Devices, and aims to enable a screwless fixing of the individual pipes in the desired position. The drawing represents an embodiment, namely is

Fig. 3 bis 6 in größerem Maßstabe Einzelheiten veranschaulichen.Fig. 3 to 6 on a larger scale details illustrate.
Von den dünnwandigen Rohren a, b, c, die schließend ineinander passen, sind die äußeren (b und c) am oberen Ende mit mehreren Längsschlitzen versehen, so daß dazwischen federnde Zungen entstehen. Hierauf passen innen schwach kegelförmig ausgebohrte Muffen d, e, die beim Verschieben der Rohre abgeschoben werden, und die beim Aufschieben die Zungen fest gegen das innere Rohr pressen und infolge der Reibung die gegenseitige Verschiebung hemmen. Ah dem dünnsten Rohre α kann nun ein Querstück/1 zur Befestigung des Besens g oder eine sonstige geeignete Befestigungsvorrichtung angebracht sein.Of the thin-walled tubes a, b, c, which fit into one another, the outer (b and c) are provided with several longitudinal slots at the upper end, so that resilient tongues are formed between them. Sockets d, e, drilled out in a slightly conical shape on the inside, fit on this and are pushed off when the pipes are moved, and which press the tongues firmly against the inner pipe when the pipes are pushed on and, as a result of the friction, inhibit the mutual displacement. Ah the thinnest tube α can now be attached a cross piece / 1 for fastening the broom g or some other suitable fastening device.
Damit man die Rohre nicht völlig herausziehen kann, sind die inneren Rohre am unteren Ende umgebörtelt (vgl. Rohr b in Fig. 3), und das umschließende Rohr c erhält an passender Stelle eine ringförmige Eindrückung ; die engeren Rohre werden in das weitere c von unten her eingeführt und dann der Stopfen h (Fig. 1) eingesetzt.So that the pipes cannot be pulled out completely, the inner pipes are crimped at the lower end (cf. pipe b in FIG. 3), and the surrounding pipe c is given an annular indentation at a suitable point; the narrower tubes are inserted into the further c from below and then the stopper h (FIG. 1) is inserted.
Die beschriebene schraubenlose Feststellung der Rohre hat die Vorzüge größter Einfachheit, Sicherheit und des Fehlens vorstehender, sich verhakender Teile.The described screwless fixing of the pipes has the advantages of great simplicity, Safety and the absence of protruding, entangling parts.
