"Teleskoprohrkupplung für Staubsauger""Telescopic pipe coupling for vacuum cleaner"
Die Neuerung betrifft eine Teleskoprohrkupplung für Staubsauger oder dergl..The innovation concerns a telescopic pipe coupling for vacuum cleaners or the like.
Es sind Teleskoprohrkupplungen bekannt, bei denen das äußere Rohr eine konische Aufbördelung aufweist. Über Kunststoffgewinde-Teile wird ein geschlitzter Klemmring gegen die konische Aufbördelung gedrückt und damit das innere Rohr festgeklemmt. Nachteilig bei dieser Ausführung ist jedoch, daß das äußere Rohr konisch aufgebördelt werden muß. Außerdem besteht die Kupplung aus drei Teilen.Telescopic pipe couplings are known in which the outer pipe has a conical flare. About plastic thread parts a slotted clamping ring is pressed against the conical flare and thus the inner tube is clamped. The disadvantage of this design, however, is that the outer tube must be flared conically. There is also the Three-part coupling.
Die Aufgabe der Neuerung ist, eine Teleskoprohrkupplung zu offenbaren, bei der die Teleskoprohre nicht mehr konisch
aufgebördelt sind, und bei der die Kupplung selbst nur aus zwei Teilen besteht.
IThe task of the innovation is to disclose a telescopic pipe coupling in which the telescopic pipes are no longer flared conically and in which the coupling itself consists of only two parts.

Der Klemmring 1 besitzt Einrastnasen 1', welche in am äußeren Rohr 2 angeordnete Öffnungen 2' einrasten. Außerdem besitzt der Klemmring 1 Klemmnasen 1" mit konischen Spannflächen 1"'. Mit dem Gewindering 3 können die Klemmnasen 1" gegen das innere Rohr 4 gedrückt werden. Die Klemmnasen 1" ragen dabei durch im äußeren Rohr 2 angeordnete Schlitze 2". Dadurch ergibt sich eine sehr gute Führung des inneren Rohres 4 in dem äußeren Rohr 2. Selbstverständlich können die Klemmnasen 1" verbreitert werden. Dadurch wird jedoch die Führung des inneren Rohres 4 verschlechtert.The clamping ring 1 has snap-in lugs 1 'which snap into openings 2' arranged on the outer tube 2. In addition, the Clamping ring 1 clamping lugs 1 "with conical clamping surfaces 1" '. With the threaded ring 3, the clamping lugs 1 ″ can be pressed against the inner tube 4. The clamping lugs 1 ″ protrude through Slots 2 ″ arranged in the outer tube 2. This results in very good guidance of the inner tube 4 in the outer one Tube 2. Of course, the clamping lugs 1 ″ can be widened Tube 4 deteriorated.
Durch die in dem inneren Rohr 4 angeordnete Nut 4' wird ein völliges Auseinanderziehen der Rohre 2 und 4 verhindert.The groove 4 'arranged in the inner tube 4 prevents the tubes 2 and 4 from being pulled apart completely.
Das innere Rohr 4 wird in den Klemmnasen 1" und den Einrastnasen 1' geführt. Da praktisch keine metallische Berührung zwischen dem inneren Rohr 4 und dem äußeren Rohr 2 besteht, ist eine Beschädigung der Oberfläche des inneren Rohres beim Verschieben der Rohre 2 und 4 nicht mehr möglich.The inner tube 4 is guided in the clamping lugs 1 ″ and the latching lugs 1 '. There is practically no metallic contact exists between the inner tube 4 and the outer tube 2, there is damage to the surface of the inner tube no longer possible when moving tubes 2 and 4.
Claims (5)
Klemmring 1 Klemmnasen 1" besitzt, welche von dem Gewindering 3 gegen das innere Rohr 4 gedrückt werden.1) Telescopic pipe coupling for vacuum cleaner or the like, characterized in that the attached to the outer pipe 2
