Description

Die Erfindung betrifft eine Saugbürste für einen Staubsauger, die zur Reinigung von harten Fußböden mit rundum einer Fassung verlaufenden Bürstenleisten und zur Reinigung von weichen Teppichen und Textilverkleidungen mit einer harten Gleit-Saugplatte versehen ist und einen Verstellmechanismus aufweist, mittels dessen nach Wahl entweder die Bürste oder die Gleit-Saugplatte in Kontakt mit dem Fußboden gebracht wird.The invention relates to a suction brush for a vacuum cleaner which is provided with a hard sliding suction plate for cleaning hard floors with brush strips running all around a socket and for cleaning soft carpets and textile cladding and has an adjustment mechanism by means of which either the brush or the sliding suction plate is brought into contact with the floor.

Aus der deutschen Patentschrift Nr. 21 36 452 ist eine Saugbürste für einen Staubsauger mit einer heraus- und hereinschiebbaren Bürste bekannt, welche in ihrem unteren Teil Saugkanäle und - öffnungen aufweist. Sie umfaßt ferner eine selbsttätige Anordnung zur Feststellung der Lage der Bürste, welche durch eine in einem Betätigungshebel eingesetzte Sperrklinke umgeschaltet wird, wobei die Klinke die Bürste aus ihrer einen Lage in die andere Lage mittels eines Drehbügels bringt. In der Anordnung zum Feststellen der Bürste befinden sich Steuerelemente, welche einige Nasen aufweisen, die die Drehbewegung des Bügels beeinflussen. Ein Nachteil dieser Lösung besteht in der komplizierten Konstruktion sowie in den technologischen Schwierigkeiten bei der Ausführung solcher Teile wie der Nasen und des Drehbügels, der in Form eines « U » ausgebildet ist. Außerdem gewährleistet diese Konstruktion nicht eine gleichmäßige Lage der Saugbürste gegenüber der zu reinigenden Fläche.From German Patent No. 21 36 452 a suction brush for a vacuum cleaner with a brush that can be pushed in and out is known, which has suction channels and openings in its lower part. It also includes an automatic arrangement for determining the position of the brush, which is switched over by a pawl inserted in an actuating lever, the pawl bringing the brush from its one position into the other position by means of a rotating bracket. In the arrangement for locking the brush there are control elements which have some lugs which influence the rotary movement of the bracket. A disadvantage of this solution is the complicated construction as well as the technological difficulties in the execution of such parts as the lugs and the rotating bracket, which is designed in the form of a "U". In addition, this construction does not ensure a uniform position of the suction brush in relation to the surface to be cleaned.

Aus der deutschen Patentschrift 2947992 ist eine Saugbürste für einen Staubsauger bekannt, die dadurch gekennzeichnet ist, daß die Verstellanordnung der Bürste ein Jochwerk in Form eines rechteckförmigen Rahmens besitzt, welches eine geradlinige Bewegung ausübt. Zur Erzeugung der geradelinigen Bewegung des Jochwerkes ist ein auskippbares Element eingesetzt, welches .,als doppelter Hebel ausgebildet ist. Ein Nachteil dieser Lösung besteht in dem komplizierten Jochwerk sowie in der komplizierten Konstruktion der Saugbürste.From German patent specification 2947992 a suction brush for a vacuum cleaner is known, which is characterized in that the adjustment arrangement of the brush has a yoke in the form of a rectangular frame, which exerts a linear movement. To generate the linear movement of the yoke, a tiltable element is used, which is designed as a double lever. A disadvantage of this solution is the complicated yoke structure and the complicated construction of the suction brush.

Aus dem deutschen Gebrauchsmuster 7 812 958 ist eine Saugplatte für eine Saugbürste eines Staubsaugers mit einem Einrillen-Saugkanal bekannt. Der Kanal weist eine gleichmäßige Breite auf und ist nur beträchtlich an den seitlichen Stirnseiten der Platte verengt, wobei er durch eine vordere und eine hintere schräge Gleitfläche eingeschränkt ist, die am Rand der Saugöffnung enden.A suction plate for a suction brush of a vacuum cleaner with a single-groove suction channel is known from German utility model 7 812 958. The channel has a uniform width and is only considerably narrowed at the lateral end faces of the plate, it being limited by a front and a rear oblique sliding surface which end at the edge of the suction opening.

Aus dem deutschen Gebrauchsmuster 7 621 523 ist eine Saugplatte für eine Staubsauger-Saugbürste mit einem Zweirillen-Saugkanal bekannt, wobei der eine Kanal seitens der Seitenflächen geschlossen und der andere Kanal seitens der Ecken offen ist und einen geradlinigen Verlauf aufweist.From German utility model 7 621 523 a suction plate for a vacuum cleaner suction brush with a two-groove suction channel is known, one channel being closed on the side surfaces and the other channel being open on the corners and having a straight course.

Ein Nachteil der Saugplatte mit Einrillen-Saugkanal besteht darin, daß die Arbeitsfläche der Platte nicht völlig ausgenutzt wird, weil darin nur ein Saugkanal untergebracht ist. Dadurch ist der Benutzer gezwungen, mehrere Bewegungen der Saugbürste auf der zu reinigenden Fläche auszuführen ; somit erhöht sich der Arbeitsaufwand für die Reinigung einer bestimmten Fläche, beispielsweise eines Teppichs oder einer Fußbodenverkleidung.A disadvantage of the suction plate with a grooved suction channel is that the working surface of the plate is not fully utilized because only one suction channel is accommodated in it. This forces the user to make several movements of the suction brush on the surface to be cleaned; this increases the workload for cleaning a certain area, for example a carpet or a floor covering.

Ein Nachteil der Saugplatte mit doppeltem Saugkanal, bei welcher der offene Kanal geradlinig verlaüft und nicht direkt mit den Ecken verbunden ist, besteht u.a. in der fehlenden Möglichkeit des Absaugens von Staub aus den Ecken der Räume.A disadvantage of the suction plate with a double suction channel, in which the open channel has a straight line and is not directly connected to the corners, is among others. in the absence of the possibility of extracting dust from the corners of the rooms.

Des weiteren ist aus der FR-A-2112137 eine Saugbürste bekannt, mit einer einschiebbaren und in den Staubsauger eingebauten Bürste, die ein Steuerelement mit zwei Wahltasten aufweist. Diese gestatten ein Anheben und Absenken der Bürste mittels einer beweglichen Platte (Bürstenfassung). Jede dieser Wahltasten besitzt eine V-Form und weist zwei schenkeiförmige Elemente auf. Das eine Element, ein sogenannter Steuerarm, reicht durch die Bohrung im Saugbürstengehäuse hindurch und ist in diesem gelagert, während das zweite Elemente, ein sogenannter Arbeitsarm, in das Innere des Saugbürstengehäuses hineinreicht und mit seinem eine Laufrolle aufweisenden Endteil unmittelbar auf der Platte aufliegt. Die Platte weist zwei in angehobener Stellung neben den Endteilen der zwei Wahltasten-Arbeitsarme liegende erhabene (nockenförmige) Wölbungen auf. Infolge des Verschwenkens der Wahltasten, deren Arbeitsarme mittels einer U-förmigen Stange senkrecht zur Drehachse verbunden sind, findet eine Verlagerung der Endteile statt. Während des Verschwenkens der Wahltasten (Druckknöpfe) laufen die Rollen über die erhebenen Wölbungen, wodurch die Platte eine senkrechte Bewegung erfährt und zugleich die an der Platte befestigte Bürste angehoben bzw. abgesenkt wird. Für eine sichere Funktion müssen Bürstenplatte und Wahltasten eine relativ genaue und starre Ausbildung aufweisen. Auch erlaubt diese bekannte Saugbürste das Absaugen von Staub aus Ecken nicht optimal.Furthermore, a suction brush is known from FR-A-2112137, with a brush which can be inserted and installed in the vacuum cleaner and which has a control element with two selection buttons. These allow the brush to be raised and lowered using a movable plate (brush holder). Each of these selection buttons has a V-shape and has two leg-shaped elements. One element, a so-called control arm, extends through the bore in the suction brush housing and is supported therein, while the second element, a so-called working arm, extends into the interior of the suction brush housing and rests directly on the plate with its end part which has a roller. The plate has two raised (cam-shaped) arches lying in the raised position next to the end parts of the two selector button working arms. As a result of the pivoting of the selection buttons, the working arms of which are connected by means of a U-shaped rod perpendicular to the axis of rotation, the end parts are displaced. While the selection buttons (push buttons) are being swiveled, the rollers run over the raised arches, as a result of which the plate experiences a vertical movement and at the same time the brush attached to the plate is raised or lowered. For a safe function, the brush plate and selection keys must have a relatively precise and rigid design. Also, this known suction brush does not optimally allow dust to be extracted from corners.

Der Erfindung liegt die Aufgabe zugrunde, die oben genannten Nachteile durch Entwicklung einer neuen, einfachen und unkomplizierten Konstruktion der Saugbürste und insbesondere einer Anordnung zum Absenken und Anheben der Bürstenfassung mit den Bürstenleisten und der Saugplatte zu beheben und gleichzeitig die Forderung an die Funktionsfähigkeit und Brauchbarkeit zu erfüllen.The invention has for its object to eliminate the above-mentioned disadvantages by developing a new, simple and uncomplicated construction of the suction brush and in particular an arrangement for lowering and lifting the brush holder with the brush strips and the suction plate and at the same time the requirement for functionality and usability fulfill.

Gemäß der Erfindung ist eine solche Saugbürste dadurch gekennzeichnet, daß der Saugkanal als Zweirillensaugkanal ausgebildet ist, bei welchem der eine Kanal in bezug auf Seitenränder der Saugplatte geschlossen ist und der andere Kanal seitens der Ecken der Saugplatte offen ist, daß die Saugplatte die Form eines Trapezes hat und seitens der längeren Seite und der Seitenränder jeweils einen Profilvorsprung aufweist, und der offene Saugkanal, der im Querschnitt die Gestalt eines Trapezes mit veränderlichen Abmessungen aufweist, seitens der Profilvorsprünge jeweils in einem Bogen verläuft und in die Ecken übergeht, die Kreisabschnitte der Vorsprünge darstellen.To achieve this object, the invention is based on a suction brush for a vacuum cleaner consisting of a body in which seats for push buttons of an adjusting mechanism for raising and lowering a brush holder with brushes arranged thereon are arranged in the upper part on both sides of a suction opening, and one below the brush holder attached arranged suction plate with a suction channel. According to the invention, such a suction brush is characterized in that the suction channel is designed as a two-groove suction channel, in which one channel is closed with respect to the side edges of the suction plate and the other channel is open on the corners of the suction plate, that the suction plate is in the shape of a trapezoid has and on the part of the longer side and the side edges each a profile projection, and the open suction channel, which has the shape of a trapezoid in cross section with variable dimensions, on the part of the profile projections runs in an arc and merges into the corners, which represent circular sections of the projections .

Die Ränder des offenen Saugkanals haben einen Radius von 1 bis 3 mm, und eine. vordere Gleitfläche ist unter einem Winkel von 8 bis 12° gegenüber einer mittleren Gleitfläche geneigt.The edges of the open suction channel have a radius of 1 to 3 mm, and one. the front sliding surface is inclined at an angle of 8 to 12 ° to a central sliding surface.

Der offene Saugkanal verläuft seitens der Saugöffnung geradlinig und seine Breite weist auf der Höhe der vorderen und der mittleren Gleitfläche einen veränderlichen Wert von 16 bis 18 mm auf, der sich im Bereich der Bögen bis auf einen Wert von 5 bis 8 mm verkleinert, während sie sich im Bereich der Ecken vergrößert.The open suction channel runs straight on the side of the suction opening and its width has a variable value of 16 to 18 mm at the height of the front and the middle sliding surface, which decreases in the area of the arches to a value of 5 to 8 mm while it increases in the area of the corners.

Die Tiefe des offenen Kanals ist veränderlich und beträgt im Bereich der Saugöffnung 7 bis 12 mm, und im Bereich der Ecken 2 bis 5 mm.The depth of the open channel is variable and is 7 to 12 mm in the area of the suction opening and 2 to 5 mm in the area of the corners.

Auf den Schenkeln eines C-förmigen Verbindungsstückes eines C-gestalteten Steuermechanismus sind die Druckknöpfe und Hebel, deren kreisförmige Enden in den ihre festen Drehpunkte bildenden Sitzen der Fassung untergebracht sind, drehbar gelagert.On the legs of a C-shaped connecting piece of a C-shaped control mechanism, the push buttons and levers, the circular ends of which are accommodated in the seats of the socket which form their fixed pivot points, are rotatably mounted.

Die Sitze der Druckknöpfe an der Innenseite des Körpers weisen Anschläge und Aussparungen zum Feststellen der Lage des Verbindungsstückes mit den Druckknöpfen und der Hebel des Mechanismus zum Anheben der Bürste auf.The seats of the push buttons on the inside of the body have stops and recesses for determining the position of the connector with the push buttons and the lever of the mechanism for lifting the brush.

The subject matter of the invention is explained in more detail below with reference to an embodiment shown in the drawing. It shows:
  • 1 shows a longitudinal section through the suction brush,
  • Fig. 2 shows the body of the suction brush with seats shown in longitudinal section, and
  • Fig. 3, the suction plate of the suction brush in a front view.

Die Saugbürste besteht aus einem Körper 1, der an den beiden Seiten einer Saugöffnung 2 Sitze 3 für einen linken und einen rechten Druckknopf 4, 5 einer Anordnung zum Anheben und Absenken einer Bürste aufweist. Die Innenteile 6, 7 des linken und des rechten Druckknopfes 4 und 5 sind an ihren Enden mit Öffnungen 8 versehen, in welchen ein Verbindungsstück 9 untergebracht ist, an dessen Enden jeweils drehbar ein Hebel 10 aufgesetzt ist, dessen eines Ende 11 in einem Formsitz 12 gelagert ist.The suction brush consists of a body 1 which has 2 seats 3 on the two sides of a suction opening for a left and a right push button 4, 5 of an arrangement for lifting and lowering a brush. The inner parts 6, 7 of the left and right push buttons 4 and 5 are provided at their ends with openings 8, in which a connecting piece 9 is accommodated, at the ends of which a lever 10 is rotatably fitted, one end 11 of which is in a molded seat 12 is stored.

Die Sitze 12 sind in einer oberen Fläche 13 einer Bürstenfassung 14 ausgeführt, in welcher Bürstenleisten 15 und 16 eingesetzt sind. Die Sitze 3 weisen in bezug auf das Innere des Körpers 1 Anschläge 17 und Aussparungen 18 zum Feststellen der Lage des Verbindungsstückes 9 und der Hebel 10 auf. Die Bürstenfassung 14 wird an die Hebel 10 durch zwei Kegelfedern 19 angepreßt, die jeweils darunter angeordnet sind und sich auf einer Saugplatte 20 abstützen, die selbst durch Schrauben 21 am Körper 1 befestigt ist.The seats 12 are embodied in an upper surface 13 of a brush holder 14, in which brush strips 15 and 16 are inserted. The seats 3 have stops 17 and recesses 18 for determining the position of the connecting piece 9 and the lever 10 with respect to the interior of the body 1. The brush holder 14 is pressed against the lever 10 by two conical springs 19, which are each arranged below and are supported on a suction plate 20, which is itself fastened to the body 1 by screws 21.

Die Saugplatte 20 hat die Gestalt eines Trapezes und weist seitens der längeren Seite 22 und der Seitenränder 23 Profilvorsprünge 24 und einen Zweirillen-Saugkanal 31, 25 auf, wobei der eine Kanal 31 seitens der Seitenränder 23 geschlossen und der andere Kanal 25 seitens der Ecken 27 der Profilvorsprünge 24 offen ist. Der offene Saugkanal 25 hat im Querschnitt die Gestalt eines Trapezes mit veränderlichen Abmessungen und verläuft seitens der Profilvorsprünge 24 in einem Bogen 26 und geht in die Ecken 27 über, welche Kreisabschnitte der Profilvorsprünge 24 bilden, die an beiden Seiten in Rändern 28 mit einem Radius von 1 bis 3 mm enden. Seitens der Saugöffnung 2 verläuft der offene Kanal 25 geradlining und seine Breite weist auf der Höhe einer vorderen Gleitfläche 29 und einer mittleren Gleitfläche 30 einen veränderlichen Wert auf.The suction plate 20 has the shape of a trapezoid and has profile projections 24 on the longer side 22 and the side edges 23 and a two-groove suction channel 31, 25, one channel 31 being closed on the side edges 23 and the other channel 25 on the corners 27 the profile projections 24 is open. The open suction channel 25 has the shape of a trapezoid with variable dimensions in cross-section and extends on the part of the profile projections 24 in an arc 26 and merges into the corners 27, which form circular sections of the profile projections 24, which are on both sides in edges 28 with a radius of End 1 to 3 mm. On the side of the suction opening 2, the open channel 25 runs in a straight line and its width has a variable value at the height of a front sliding surface 29 and a central sliding surface 30.

Die Arbeitsweise der Saugbürste kann folgendermaßen beschrieben werden :The operation of the suction brush can be described as follows:

In einer ersten Lage, in der die Bürstenfassung 14 samt Bürstenleisten 15 und 16 in das Innere des Körpers 1 eingezogen ist, ist die Stellung der Anordnung zum Anheben und Absenken der Bürste derart, daß der rechte Druckknopf 5 in den Sitz 3 des Körpers 1 eingedrückt ist, so daß sein Innenteil 7 samt dem Verbindungsstück 9 und dem Hebel 10 sich in der extremen Lage am nächsten der Innenwand des Körpers 1 befinden, während die Schenkel des Verbindugsstückes 9 in den Aussparungen 18 des Sitzes 3 liegen und in dieser Lage durch die Druckkraft der Kegelfedem 19 über die Enden der Hebel 10 gehalten werden, die in den Formsitzen 12 der Bürstenfassung gelagert sind. Da das Verbindungsstück 9 die Gestalt eines C-Profils hat und durch die Schenkel der Innenteile 6, 7 des linken Drucknopfes 4 und des rechten Druckkknopfes 5 sowie die beiden Hebel 10 hindurchgreift, ist ein Gestänge gebildet, dessen Elemente eng verbunden sind. Dadurch ist der linke Druckknopf 4 höchstmöglich nach oben angehoben. In solcher Lage arbeitet die Saugbürste mit ihrer Saugplatte 20 zur Reinigung beispielsweise weicher Teppiche.In a first position, in which the brush holder 14 together with brush strips 15 and 16 is drawn into the interior of the body 1, the position of the arrangement for raising and lowering the brush is such that the right push button 5 is pressed into the seat 3 of the body 1 is so that its inner part 7 together with the connecting piece 9 and the lever 10 are in the extreme position closest to the inner wall of the body 1, while the legs of the connecting piece 9 lie in the recesses 18 of the seat 3 and in this position by the pressure force the conical spring 19 are held over the ends of the levers 10 which are mounted in the molded seats 12 of the brush holder. Since the connecting piece 9 has the shape of a C-profile and extends through the legs of the inner parts 6, 7 of the left push button 4 and the right push button 5 and the two levers 10, a linkage is formed, the elements of which are closely connected. As a result, the left push button 4 is raised as far as possible. In this position, the suction brush works with its suction plate 20 for cleaning soft carpets, for example.

Durch Druck auf den linken Druckknopf 4 wird eine Verlagerung der Elemente zur Umschaltung bewirkt, wodurch ein Herausschieben der Bürstenfassung 14 samt den Bürstenleisten 15 und 16 aus dem Körper 1 in eine Arbeitsstellung erreicht wird. In dieser Lage stützen sich die Schenkel des Verbindungsstückes 9 auf den Anschlägen 17 ab. Der rechte Druckknopf 5 ist über den Körper 1 hinaus angehoben. Damit arbeitet die Saugbürste mit ihren Bürstenleisten 15 und 16.By pressing the left push button 4, the elements for switching are shifted, whereby the brush holder 14 together with the brush strips 15 and 16 is pushed out of the body 1 into a working position. In this position, the legs of the connecting piece 9 are supported on the stops 17. The right push button 5 is raised beyond the body 1. The suction brush thus works with its brush strips 15 and 16.

Nach dem Eindrücken des rechten Druckknopfes 5 verlagert sich wieder die Bürstenfassung 14 samt den Bürstenleisten 15 und 16 in das Innere des Körpers 1 und alle Vorgänge verlaufen in entgegengesetzter Richtung.After the right push button 5 has been pressed in, the brush holder 14, together with the brush strips 15 and 16, again moves into the interior of the body 1 and all processes take place in opposite direction.

Die erfindungsgemäße Saugbürste erlaubt es also dem Benutzer, schnell und sicher die Arbeitsart mit Bürste oder mit Saugplatte je nach Bedarf zu wählen und sichert dadurch vollkommen die Forderungen nach optimaler Funktionsfähigkeit und Brauchbarkeit.The suction brush according to the invention thus allows the user to quickly and safely choose the type of work with a brush or with a suction plate as required and thereby completely ensures the requirements for optimal functionality and usability.
