Description
Einrichtung für den Anschluss von Schläuchen und Rohren an Hohlkörpern. Es kommen Anschlüsse von Schläuchen und Rohren an Hohlkörpern vor, welche ohne Verschraubung oder Bajonettverschluss be werkstelligt werden. Die vorliegende Erfin dung bezieht sich auf eine Einrichtung für einen solchen Anschluss, bei welchem ein mit zum Beispiel konischem Kopfstück versehener Schlauch oder biegsames oder starres Rohr an einen Hohlkörper angeschlossen werden soll.
Der Hohlkörper besitzt erfindungsgemäss einen Anschlussstutzen, auf welchen ein ela stischer Ring angesteckt ist, der sich nach Einführung des Kopfstückes des Schlauches oder Rohres an die Mantelfläche des Kopf stückes anzuschmiegen und es durch Reibung so zu halten vermag, dass das Kopfstück mit dem Schlauch oder Rohr gedreht werden kann, ohne sich hierbei gleich vom Stutzen loszutrennen.
Die beigegebene Zeichnung stellt an einem Gehäuse zur Aufnahme des von einem elek trischen Staubsaugeapparatangesaugten Stau bes und Unrates ein Ausführungsbeispiel des Erfindungsgegenstandes dar. Fig. 1 ist ein Längsschnitt eines Hohlkörpers, an dessen einem Ende ein Schlauch oder Rohr ange- schlossen werden soll; Fig.2 ein Längs schnitt des an jenem Ende anzustecken be stimmten elastischen Ringe.
Die vordere Stirnwand<I>a</I> des Gehäuses g, in dessen hinterem Teil ein Elektromotor mit Ventilator eingebaut zu denken ist, weist einen inwendig mit Isoliermaterial gefütterten Anschlussstutzen <I>b</I> auf, dessen Durchgang<I>d</I> in der Weise konisch ist, dass die lichte Weite am vordern Ende etwas grösser ist als an der dem Gehäuseinnern zugekehrten Seite. Auswendig ist der Stutzen b mit einer Nut c hinter einem Bundring e versehen.
Auf den Anschlussstutzen ist ein elastischer Ring ic, am besten aus Gummi, gesteckt, der einen nach innen ragenden, in die Nut c eingreifenden Stirnflansch s und eine auf den Bundring e passende Nut t besitzt. Das Kopfende des Ringes u weist eine Durch- gangsöffnung auf, deren lichte Weite minde stens nicht grösser, sondern vorteilhafterweise etwas kleiner ist als diejenige des vordern Endes des Anschlussstutzens b.
Nachdem das konische Kopfstück r eines Schlauches oder Rohres in den entsprechend konischen Anschlussstutzen b eingeschoben ist, schmiegt sich das Kopfende des elasti schen Ringes u eng an jenes Kopfstück an und verhindert dessen Lostrennung vom An schlussstutzen, lässt aber Drehungen und Schwenkungen des Schlauches oder Rohres zu. Durch die erwähnte Ausführung des An schlussstutzens b mit Isoliermaterial und den Gummiring u ist die den Schlauch oder das Rohr handhabende Person gegen allfällige unliebsame Einwirkungen des Elektromotors geschützt.
Device for connecting hoses and pipes to hollow bodies. There are connections of hoses and pipes to hollow bodies, which are made without screwing or bayonet lock. The present invention relates to a device for such a connection, in which a hose provided with, for example, a conical head piece or a flexible or rigid pipe is to be connected to a hollow body.
According to the invention, the hollow body has a connection piece to which an elastic ring is attached which, after the head piece of the hose or pipe has been introduced, clings to the surface of the head piece and is able to hold it by friction so that the head piece with the hose or pipe can be rotated without separating from the nozzle.
The accompanying drawing shows an exemplary embodiment of the subject matter of the invention on a housing for receiving the dust and debris sucked in by an electric vacuum cleaner. FIG. 1 is a longitudinal section of a hollow body, at one end of which a hose or pipe is to be connected; 2 shows a longitudinal section of the elastic rings to be attached to that end.
The front end wall <I> a </I> of the housing g, in the rear part of which an electric motor with a fan is to be imagined, has a connection piece <I> b </I> which is internally lined with insulating material and whose passage <I> d </I> is conical in such a way that the clear width at the front end is slightly larger than on the side facing the inside of the housing. On the outside, the connector b is provided with a groove c behind a collar e.
An elastic ring ic, preferably made of rubber, is plugged onto the connecting piece and has an inwardly protruding end flange s that engages in the groove c and a groove t that fits onto the collar e. The head end of the ring u has a through opening, the clear width of which is at least not larger, but advantageously somewhat smaller than that of the front end of the connecting piece b.
After the conical head piece r of a hose or pipe has been pushed into the corresponding conical connection piece b, the head end of the elastic ring u clings closely to that head piece and prevents it from being separated from the connection piece, but allows the hose or pipe to rotate and swivel . Due to the aforementioned execution of the connection piece b with insulating material and the rubber ring u, the person handling the hose or pipe is protected against any undesirable effects of the electric motor.
