Description
Düse zum Aufpumpen von aufblasbaren Gegenständen Nozzle for inflating inflatable objects
BESCHREIBUNGDESCRIPTION
Die Neuerung betrifft eine Düse zum Aufblasen von aufblasbaren Gegenständen, z.B. von Freizeitartikeln, bzw. Luftkissen, Schlauchbooten etc..The innovation concerns a nozzle for inflating inflatable objects, e.g. of leisure items or air cushions, inflatables etc.
Der Neuerung liegt die Aufgabe zugrunde, eine Düse zum Aufblasen von aufblasbaren Gegenständen anzubieten, welche eine erhöhte Pumpleistung besitzt.The innovation is based on the task of offering a nozzle for inflating inflatable objects, which has an increased pumping capacity.
Diese Aufgabe wird durch eine Düse mit den Merkmalen des Schutzanspruchs 1 gelöst. Vorteilhafte Ausführungsformen der Düse werden in den Unteransprüchen 2 - 11 beschrieben.This object is achieved by a nozzle with the features of protection claim 1. Advantageous embodiments of the nozzle are described in subclaims 2-11.
Bei der neuerungsgemäßen Düse ist ein Düsenkanal zur Führung von Luft vorgesehen, wobei der Düsenkanal mindestens eine seitliche Öffnung aufweist. Beim Zuführen von Luft zum Aufpumpen der aufblasbaren Gegenstände wird diese Luft in den Düsenkanal eingeführt, an der Stelle, an der sich die seitliche Öffnung des Düsenkanals befindet, vorbeigeführt und weiter im Düsenkanal in das Innere des aufblasbaren Gegenstandes hineingeführt. Überraschenderweise entsteht durch die angebrachte seitliche Öffnung des Düsenkanals kein Verlust der Pumpleistung, vielmehr steigert sich die Pumpleistung. Damit kann die Aufpumpzeit zum Aufpumpen von aufblasbaren Gegenständen deutlich verkürzt werden.In the nozzle according to the innovation, a nozzle channel for guiding air is provided, the nozzle channel having at least one lateral opening. When air is supplied to inflate the inflatable objects, this air is introduced into the nozzle channel, past the point at which the lateral opening of the nozzle channel is located, and further into the interior of the inflatable object in the nozzle channel. Surprisingly, the lateral opening of the nozzle channel does not result in a loss of pump power, rather the pump power increases. This significantly reduces the inflation time for inflating inflatable objects.
Nach einer vorteilhaften Ausführungsform ist die seitliche Öffnung als Bohrung ausgebildet und mündet seitlich in den Düsenkanal.According to an advantageous embodiment, the lateral opening is designed as a bore and opens laterally into the nozzle channel.
Gemäß einer weiteren vorteilhaften Ausführungsform besitzt der Düsenkanal einen Abschnitt mit bereichsweise abnehmendem Durchmesser. Hierdurch kann eine Beschleunigung der eingepumpten Luft erreicht werden.According to a further advantageous embodiment, the nozzle channel has a section with a decreasing diameter in some areas. As a result, the pumped-in air can be accelerated.
Bei Verwendung eines Rückschlagsventils kann ein unerwünschtes Entweichen von Luft aus dem aufblasbaren Gegenstand vermieden werden. Die in den Gegenstand eingeführte Luft verbleibt somit im Gegenstand und kann nicht entweichen, auch wenn während des Aufpumpens eine Unterbrechung auftritt.When using a check valve, an undesirable escape of air from the inflatable object can be avoided. The air introduced into the article thus remains in the article and cannot escape, even if an interruption occurs during inflation.
Das Rückschlagventil kann dabei auf verschiedene an sich bekannte Art und Weise und in einer besonders einfachen und kostengünstig herstellbaren Ausführungsform als Klappe ausgebildet sein.The check valve can be designed as a flap in various ways known per se and in a particularly simple and inexpensive embodiment.
Nach einer weiteren vorteilhaften Ausführungsform ist die seitliche Öffnung des Düsenkanals, z.B. über eine Hülse, abdeckbar. Bei Verschiebung der Abdeckung, kann die Größe der seitlichen Öffnung (Öffnungsgrad) variiert werden. Hierdurch kann der beim Aufpumpen auftretende Ansaugeffekt variiert und verstärkt oder vermindert werden. So kann beim anfänglichen Aufpumpen, z.B. ein größerer Öffnungsgrad gewählt werden. Beim abschließenden und sich dem Ende nähernden Aufpumpen kann zur Erhöhung eines größeren Pumpendruckes die seitliche Öffnung verringert bzw. ganz geschlossen werden. Im umgekehrten Fall kann durch Öffnen der seitlichen Öffnungen ein Überdruck im aufzupumpenden Gegenstand vermieden werden.According to a further advantageous embodiment, the lateral opening of the nozzle channel can be covered, for example via a sleeve. When the cover is moved, the size of the side opening (degree of opening) can be varied. As a result, the suction effect that occurs when inflating can be varied and increased or reduced. For example, during the initial inflation, a larger one Degree of opening can be selected. When pumping up and approaching the end, the side opening can be reduced or closed completely to increase a higher pump pressure. In the opposite case, overpressure in the object to be inflated can be avoided by opening the side openings.
Gemäß einer weiteren vorteilhaften Ausführungsform besitzt der Düsenkanal mindestens ein Filterelement zur Luftreinigung der zugeführten Luft, um zu vermeiden, daß Schmutzpartikel die Durchgangsbohrung verschließen.According to a further advantageous embodiment, the nozzle channel has at least one filter element for air purification of the supplied air, in order to prevent dirt particles from closing the through hole.
Wenn der aufblasbare Gegenstand ein Rückflußventil zur Vermeidung des unbeabsichtigten Entweichen von Luft aufweist, kann die Düse vorteilhafterweise frontseitig eine Verlängerung zum Öffnen eines derartigen Rückflußventils beim Einführen der Düse in den aufblasbaren Gegenstand besitzen.If the inflatable object has a reflux valve to prevent the unintentional escape of air, the nozzle can advantageously have an extension on the front for opening such a reflux valve when the nozzle is inserted into the inflatable object.
Nach einer weiteren vorteilhaften Ausführungsform kann die Düse ein Gewinde zum Anbringen von Reifenfüllvorrichtungen zum beschleunigten Befüllen eines aufblasbaren Gegenstandes aufweisen.According to a further advantageous embodiment, the nozzle can have a thread for attaching tire inflation devices for the accelerated filling of an inflatable object.

Fig. 1 ein Längsschnitt einer Düse mit geöffneter Hülse sowie Fig. 2 ein Längsschnitt gemäß Fig. 1 mit geschlossener Hülse.Fig. 1 is a longitudinal section of a nozzle with the sleeve open and Fig. 2 is a longitudinal section according to FIG. 1 with the sleeve closed.
Fig. 1 zeigt eine im wesentlichen als Rundkörper ausgebildete Düse 1 als Längsschnitt mit einem Gewinde 2 zur Anbringung an einem Reifenfüllgerät. Im Eingangsbereich 3 der Düse 1 ist ein Filterelement 4 zur Reinigung der zugeführten Luft vorgesehen. Hinter dem Filter 4 ist eine Düsenbohrung 5 mit verringertem Durchmesser zur Beschleunigung der zugeführten Luft vorgesehen. Dahinter befindet sich die seitliche (durchgängige) Öffnung 6. Im Anschluß daran wird die Düse 1 durch den Düsenkanal 7 fortgeführt, welcher mit einem Rückschlagventil 8 (z.B. einer Klappe) abschließt.1 shows a nozzle 1, which is essentially designed as a round body, as a longitudinal section with a thread 2 for attachment to a tire inflation device. A filter element 4 for cleaning the supplied air is provided in the inlet area 3 of the nozzle 1. A nozzle bore 5 with a reduced diameter is provided behind the filter 4 to accelerate the air supplied. Behind it is the lateral (continuous) opening 6. Subsequently, the nozzle 1 is continued through the nozzle channel 7, which closes with a check valve 8 (e.g. a flap).
Danach verengt sich die Düse 1 bis hin zur Austrittsöffnung 9. Im Anschluß daran ist eine teilweise Verlängerung 11 angebracht, die beim Einführen in die Öffnung des aufblasbaren Gegenstandes die dort befindliche Klappe zurückstoßen kann. Auf der Düse 1 befindet sich eine Hülse 12, welche in Fig. 1 in einer zurückgeschobenen und in Fig. 2 in einer geschlossenen Position abgebildet ist. In der zurückgeschobenen Position nach Fig. 1 ist die Öffnung 6 vollständig geöffnet. In der geschlossenen Position nach Fig. 2 ist die Öffnung 6 vollständig geschlossen.Thereafter, the nozzle 1 narrows to the outlet opening 9. Subsequently, a partial extension 11 is attached, which can push back the flap located there when inserted into the opening of the inflatable object. A sleeve 12 is located on the nozzle 1, which is shown in a retracted position in FIG. 1 and in a closed position in FIG. 2. In the retracted position according to FIG. 1, the opening 6 is completely open. In the closed position according to FIG. 2, the opening 6 is completely closed.
Die Hülse 12 kann auch in mittleren Positionen eingestellt werden, um damit den Öffnungsgrad der Öffnung 6 einzustellen um den im Inneren des aufblasbaren Gegenstandes sich aufbauenden Druck zu regulieren (nicht abgebildet). Auch kann die Befestigung der Hülse auf der Düse durch ein Gewinde erfolgen, das gleichzeitig eine Feineinstellung erlaubt, eventuell mit Skalierung. The sleeve 12 can also be adjusted in middle positions in order to adjust the opening degree of the opening 6 in order to regulate the pressure building up inside the inflatable object (not shown). The sleeve can also be attached to the nozzle by means of a thread, which at the same time allows fine adjustment, possibly with scaling.
