Description

Die Erfindung betrifft einen Sauger, insbesondere Werkstattsauger, zum Auf- und/oder Absaugen von Spänen und/oder Staub mit einem vorzugsweise mit Rollen versehenen Unterteil, einem hierauf aufnehmbaren Auffangbehälter und einem diesen verschließenden Oberteil, das einen motorisch antreibbaren Ventilator und eine diesen vom Innenraum des Auffangbehälters trennende Filterpatrone aufweist, wobei ein in den Auffangbehälter mündender, mit einem Anschlussstutzen versehener Lufteinlass und ein dem Ventilator zugeordneter Luftauslass vorgesehen sind.The invention relates to a sucker, in particular workshop vacuum cleaner, for suction and / or suction of chips and / or dust with a preferably provided with rollers lower part, a receptacle on this receptacle and a closing this upper part, a motor driven fan and this from the interior having the collecting container separating filter cartridge, wherein an opening into the collecting container, provided with a connecting piece air inlet and a fan associated with the air outlet are provided.

Bei den bekannten Anordnungen dieser Art ist der Auffangbehälter als topfartiges Formteil ausgebildet. Dieses Formteil ist in sich steif und legt damit die Gerätehöhe für alle Fälle fest. Es ergibt sich daher ein vergleichsweise hohes Transportvolumen, was nicht nur zu hohen Transportkosten bei der Auslieferung führt, sondern auch zu einem vergleichsweise großen Raumbedarf bei mobilem Einsatz des Saugers. Dies wirkt sich ungünstig auf die erreichbare Gesamtwirtschaftlichkeit aus.In the known arrangements of this type, the collecting container is designed as a pot-shaped molding. This molded part is inherently stiff and thus defines the device height for all cases. There is therefore a comparatively high transport volume, which not only leads to high transport costs during delivery, but also to a relatively large space requirement for mobile use of the nipple. This has an unfavorable effect on the achievable overall economy.

Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung einen Sauger eingangs erwähnter Art mit einfachen und kostengünstigen Mitteln unter Beibehaltung der grundsätzlichen Vorteile so zu verbessern, dass die Gerätehöhe veränderbar ist.On this basis, it is therefore an object of the present invention to improve a sucker of the type mentioned with simple and inexpensive means while maintaining the basic advantages so that the device height is variable.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass zwischen Unterteil und Oberteil eine teleskopartig ausgebildete Stützeinrichtung angeordnet ist, der eine Aufnahmeeinrichtung für den oberen Endbereich des Auffangbehälters zugeordnet ist, der in axialer Richtung zusammenschiebbar und bodenseitig am Unterteil festlegbar ist.This object is achieved in that between the lower part and upper part a telescopically formed support means is arranged, which is associated with a receiving device for the upper end of the collection container is, which is collapsible in the axial direction and the bottom side of the lower part can be fixed.

Mit diesen Maßnahmen werden die oben geschilderten Nachteile des gattungsgemäßen Standes der Technik vollständig beseitigt. Die teleskopartig ausgebildete Stützeinrichtung ermöglicht in Verbindung mit dem in der Höhe stauchbaren Auffangbehälter eine Veränderung der Gerätehöhe zwischen dem minimalen und maximalen Ausschub der teleskopartigen Stützeinrichtung. Der erfindungsgemäße Sauger kann daher in vorteilhafter Weise für Transportzwecke auf eine geringe Gerätehöhe zusammengeschoben und für den Gebrauch auf die maximale Gerätehöhe auseinandergezogen werden, so dass ein großes Fassungsvermögen des Auffangbehälters bereitgestellt wird.With these measures, the above-described disadvantages of the generic state of the art are completely eliminated. The telescopically formed support device, in conjunction with the height-constrictable collecting container allows a change in the height of the device between the minimum and maximum extension of the telescopic support device. The sucker according to the invention can therefore be pushed together advantageously for transport purposes to a low device height and pulled apart for use to the maximum device height, so that a large capacity of the collecting container is provided.

Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den Unteransprüchen angegeben.Advantageous embodiments and expedient developments of the higher-level measures are specified in the subclaims.

So kann der Auffangbehälter zweckmäßig als aus einem in sich beweglichen, luftdichten Material, vorzugsweise einer Kunststoffhaut, bestehender Sack ausgebildet sein, der in radialer Richtung mittels einer zweckmäßig als in die Wandung des Auffangbehälters eingebaute Spirale ausgebildeten Aufspanneinrichtung aufgespannt ist. Diese Maßnahmen ergeben einen Auffangbehälter mit hohem Fassungsvermögen, der in axialer Richtung leicht und einfach um ein großes Maß zusammengestaucht werden kann.Thus, the collecting container may expediently be formed as consisting of a movable in itself, airtight material, preferably a plastic skin, existing sack, which is clamped in the radial direction by means of a suitably designed as built into the wall of the collecting container spiral clamping device. These measures result in a collecting container with high capacity, which can be easily and easily compressed in the axial direction by a large amount.

Zweckmäßig kann das Unterteil mit vorzugsweise zwei einander gegenüberliegenden Zungen versehen sein, die jeweils mit einer zugeordneten Tasche des Auffangbehälters zum Eingriff bringbar sind. Auf diese Weise wird eine einfache und zuverlässige bodenseitige Festlegung des Auffangbehälters erreicht.Suitably, the lower part can be provided with preferably two opposing tongues, which can be brought into engagement with an associated pocket of the collecting container. In this way, a simple and reliable bottom-side fixing of the collecting container is achieved.

Eine weitere vorteilhafte Maßnahme kann darin bestehen, dass die Stützeinrichtung vorzugsweise zwei einander gegenüberliegende Stützen aufweist, die durch teleskopartig ineinander eingreifende T-Profile gebildet werden. Diese Maßnahmen ergeben eine hohe Biegesteifigkeit der Stützen und ermöglichen dennoch eine einfache und kostengünstige Herstellung. Die ineinander eingreifenden Teile der Stützen können einfach mittels einer Spannschraube in der gewünschten Auszugslänge aneinander festgelegt werden.A further advantageous measure may consist in that the support device preferably has two opposing supports formed by telescoping T-profiles become. These measures result in a high bending stiffness of the supports and still allow a simple and inexpensive production. The interlocking parts of the supports can be easily fixed together by means of a clamping screw in the desired extension length.

Vorteilhaft können die Stützen mit ihren unteren Enden nach Art von Steckzapfen in zugeordnete Einsteckausnehmungen des Unterteils einsteckbar bzw. einrastbar sein. Hierdurch ergibt sich eine einfache Montage.Advantageously, the supports can be inserted or latched with their lower ends in the manner of plug-in pins in associated Einsteckausnehmungen of the lower part. This results in a simple installation.

Mit Vorteil kann die auf der Stützeinrichtung aufgenommene Aufnahmeeinrichtung für den Auffangbehälter als ringförmig umlaufender Steg ausgebildet sein, an dem in die oberen Enden der Stützen einsteckbare bzw. einrastbare Steckzapfen angebracht sind. Auch hierdurch wird die Montage des erfindungsgemäßen Saugers stark vereinfacht.Advantageously, the recorded on the support means receiving means for the collecting container may be formed as an annular circumferential ridge, are attached to the plug in the upper ends of the supports or snap-in. This also greatly simplifies the assembly of the vacuum cleaner according to the invention.

In weiterer Fortbildung der übergeordneten Maßnahmen kann das Oberteil mit einem die Filterpatrone umgebenden Ringraum versehen sein, in den der Lufteinlass vorzugsweise tangential einmündet. Dieser Ringraum bietet im Transportzustand genügend Platz zur Aufnahme eines an einen dem Lufteinlass zugeordneten Anschlussstutzen ansteckbaren Saugschlauchs, so dass dieser für Transportzwecke schonend und platzsparend verstaubar ist.In a further development of the higher-level measures, the upper part can be provided with an annular space surrounding the filter cartridge into which the air inlet preferably opens tangentially. This annular space provides sufficient space in the transport state for receiving a hose connected to the air inlet connection piece attachable suction hose, so that it is gently and space-saving stowed for transport purposes.

Zweckmäßig können an den Saugschlauch unterschiedliche Düsen ansteckbar sein. Um diese übersichtlich und zuverlässig unterbringen zu können, ist das Unterteil zweckmäßig mit Einsteckausnehmungen für einen Düsensatz versehen. Das Unterteil ist vorteilhaft einfach als Plattform mit Rollen und mit Einsteckausnehmungen für die Stützen und die Düsen sowie mit den oben genannten Laschen zur Halterung des Auffangbehälters ausgebildet.Appropriately, different nozzles can be attached to the suction hose. In order to accommodate this clear and reliable, the lower part is expediently provided with Einsteckausnehmungen for a nozzle set. The lower part is advantageously designed simply as a platform with rollers and with insertion recesses for the supports and the nozzles and with the abovementioned tabs for holding the collecting container.

Weitere vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen ergeben sich aus den restlichen Unteransprüchen und sind aus der nachstehenden Beispielsbeschreibung anhand der Zeichnung näher entnehmbar.Further advantageous embodiments and expedient developments of the parent measures will become apparent from the remaining dependent claims and are apparent from the following example description with reference to the drawings.
