Description

Die Erfindung bezieht sich auf eine Bürstabdeakung für rotierend angetriebene walzenförmige Reinigungsbürsten, insbesondere an Handbürst- bzw. Handbürstsauggeräten mit vorzugsweise mehreren in Abständen voneinander zwischen die Borstenbüschel der Bürste eingreifenden Querstegen.The invention relates to brush brushing for rotatingly driven roller-shaped cleaning brushes, in particular on hand-brush or hand-brush suction devices, preferably with a plurality of transverse webs which engage between the bristle tufts of the brush.

Eine Bürstabdeckung bei solchen Geräten hat nicht nur den Zweck, den aufgebürsteten Staub einem Absaugkanal zuzuführen, sondern auch das Herumwickeln von losen Gegenständen, z. B. von Kleidungsstücken u. dgl., um die Bürste zu vermeiden. Dieselbe kann aber auch noch dazu ausgebildet sein, die durch die Bürste mitgenommenen Fäden abzustreifen, um diese einem Auffangbehälter zuzuführen bzw. in einen Absaugkanal abzuleiten, wie dies beispielsweise in den bekannten Geräten gemäß der DE-OS 23 33 817 oder der Oe Patentschrift Nr. 308 23 bzw. der Oe Patentschrift Nr. 297 647 beschrieben ist. Um dies zu ermöglichen, werden quer zur Bürstachse sog. Abstreifkämme im oberen Bereich der Bürste, d. h. an der dem Reinigungsgegenstand entgegengesetzten Seite, so angeordnet, daß die abgestreiften Fäden ohne Behinderung einem anschliessenden Auffangbehälter oder einem Absaugkanal zugeführt werden können. Die Ableitung der abgestreiften Fäden ist dann am wirksamsten, wenn der Abstreifkamm an der nach abwärts gerichteten Drehseite der Bürste angeordnet ist (DE-OS 2333817). Bei allen bisher bekannten Bürstabdeckungen besteht aber weiterhin die Gefahr, daß durch die rotierende Bürste lose Gegenstände an der Unterseite der Abdeckung hineingezogen werden. Selbst bei einer knapp um die Bürste und bis an die untere Mantellinie derselben angeordneten Abdeckung verbleibt an den borstenfreien Stellen der Bürste ein genügend großer Spalt, der sich von der Abdeckung bis zur Bürstwelle hin erstreckt, welcher zusammen mit der Elastizität der Borstenbüschel diese gefährliche Eigenschaft rotierender Bürsten ermöglicht. Besonders bei motorisch angetriebenen Handbürstgeräten, deren Handlichkeit dazu führt, daß diese sehr leicht in die Nähe der Kleidung der Bedienungsperson gebracht werden können, bedeutet dies eine Gefährdung derselben. Nicht zuletzt ist aus diesem Grund eine Beschädigung einer solchen Vorrichtung durch die wesentlich höhere Bürstumdrehung, im Gegensatz zu manuell bewegbaren Bodenkehrgeräten, unvermeidbar.A brush cover in such devices not only has the purpose of supplying the brushed dust to a suction channel, but also the winding around of loose objects, e.g. B. of clothing u. Like. To avoid the brush. However, the same can also be designed to strip off the threads entrained by the brush in order to feed them to a collecting container or to discharge them into a suction channel, as is the case, for example, in the known devices according to DE-OS 23 33 817 or Oe Patent Specification No. 308 23 or Oe Patent Specification No. 297 647. To make this possible, so-called scraper combs are arranged transversely to the brush axis in the upper region of the brush, ie on the side opposite the cleaning object, in such a way that the stripped threads can be fed without hindrance to a subsequent collecting container or a suction channel. The stripping of the stripped threads is most effective when the stripping comb is arranged on the downward rotating side of the brush (DE-OS 2333817). With all previously known brush covers, however, there is still the risk that loose objects on the underside of the cover will be drawn in by the rotating brush. Even with a cover arranged just around the brush and up to the lower surface line of the same, a sufficiently large gap remains at the bristle-free points of the brush, which extends from the cover to the brush shaft, which, together with the elasticity of the bristle tufts, rotates this dangerous property Allows brushing. Particularly in the case of motor-driven hand brushing devices, the handiness of which means that they can very easily be brought close to the clothing of the operator, this means that the same is at risk. Last but not least, damage to such a device due to the significantly higher brush revolution, in contrast to manually movable floor sweepers, is unavoidable.

Die in den oben angeführten Patentschriften beschriebenen Anordnungen sind aber keineswegs in der Lage, das Hineinziehen loser Gegenstände zu verhindern,und somit eine Beschädigung der Vorrichtung oder die Gefährdung der diese bedienenden Person zu vermeiden, da die nachteiligen Folgen bereits dann voll wirksam sind, wenn Kleidungsstücke o. ä. über die Achsmitte der Bürste hineingezogen werden.However, the arrangements described in the above-mentioned patents are in no way able to prevent loose objects from being pulled in, and thus to prevent damage to the device or the danger to the person operating it, since the disadvantageous consequences are already fully effective when clothing items are used or the like over the center of the axis of the brush.

Zweck der Erfindung ist es, eine Bürstabdeckung zu schaffen, welche diese Nachteile vermeidet und einen besseren Schutz für die das Gerät bedienende Person gewährleistet.The purpose of the invention is to provide a brush cover which avoids these disadvantages and ensures better protection for the person operating the device.

Erfindungsgemfß wird dies dadurch erreicht, wenn die Querstege an der der Reinigungsseite gelegenen Bürsthälfte im Bereich der offenen Unterseite der Abdeckung zwischen die . Borstenbüschel der Bürste eingreifen. Schon die Anordnung eines einzigen Steges zwischen zwei Borstenbüscheln gemäß der Erfindung, z. B.-in der halben freien Länge der Bürste, erschwert das Hineinziehen loser Gegenstände zwischen Bürste und Abdeckung. Vorteilhaft-ist es, mehrere Stege in Abständen voneinander zu verwenden, welche so angeordnet sind, daß die Borstenbüschel mindestens einige Millimeter unter diesen vorstehen, sodaß der-Reinigungsvorgang durch dieselben nicht behindert bzw. eingeschränkt wird. Die zweckmäßigerweise mit rechteckigem Querschnitt ausgebildeten Querstege können dabei auch in einem schrägen Winkel zur Bürstachse angeordnet sein. F ß invention, this is achieved if the transverse webs situated at the side of the cleaning Bürsthälfte in the region of the open bottom of the cover between the. Engage the bristle tufts of the brush. Already the arrangement of a single web between two tufts of bristles according to the invention, for. B.-in half the free length of the brush, it is difficult to pull loose objects between Brush and cover. It is advantageous to use a plurality of webs at intervals from one another which are arranged in such a way that the bristle tufts protrude at least a few millimeters below them, so that the cleaning process is not hindered or restricted by them. The transverse webs, which are expediently designed with a rectangular cross section, can also be arranged at an oblique angle to the brush axis.

Die Anbringung der Querstege kann in einer Weiterbildung der Erfindung dadurch erfolgen, daß diese an der nach aufwärts gerichteten Drehseite der Bürste zwischen der Abdeckung und der Bürstwelle angeordnet sind. Dabei ist es zweckmäßig, die einzelnen bis etwa an die Bürstwelle reichenden Querstege einstückig mit der Abdeckung zu fertigen.In a further development of the invention, the transverse webs can be attached by arranging them on the upward rotating side of the brush between the cover and the brush shaft. It is expedient to manufacture the individual transverse webs reaching approximately to the brush shaft in one piece with the cover.

Besonders vorteilbringend ist es aber, wenn gemäß einer anderen, für alle Bürstanordnungen geeigneten Weiterbildung der Erfindung, die Querstege unterhalb der Bürstwelle(n) an der gesamten Breite der Bürstabdeckung durchgehend angeordnet sind. Damit ist auch eine leicht austauschbare Anbringung derselben an der Abdeckung möglich.However, it is particularly advantageous if, according to another development of the invention which is suitable for all brush arrangements, the transverse webs are arranged continuously below the brush shaft (s) along the entire width of the brush cover. This also allows an easily replaceable attachment to the cover.

Diese kann gemäß einer vorteilhaften Fortbildung der Erfindung dadurch erfolgen, daß die Querstege mittels beiderseits an diesen anbringbaren Längsstegen an der Unterseite der Abdeckung einsetzbar sind. Die'Querstege bilden daher mit den Längsstegen einen Rahmen, welcher beispielsweise durch Eigenspannung oder mit Hilfe von federnden Klammern in der Abdeckung haltbar angebracht werden kann.According to an advantageous further development of the invention, this can be achieved in that the transverse webs can be used on the underside of the cover by means of longitudinal webs which can be attached to these on both sides. The crossbars therefore form a frame with the longitudinal webs, which can be attached to the cover in a durable manner, for example by internal tension or with the aid of spring clips.

Bei zwei oder mehreren parallel nebeneinander angeordneten mit nach innen gerichteter Drehrichtung angetriebenen Reinigungsbürsten können gemäß einer weiteren vorteilbringenden Fortbildung der Erfindung die Querstege an einem zwischen den Bürsten, vorzugsweise unter dem Schnittpunkt der Mantellinien derselben liegenden, an der Abdeckung anbringbaren Längssteg angeordnet sein. Es ist dabei auch möglich, den Achsabstand beider Bürsten zu vergrößern und den Längssteg zwischen den Bürsten ggf. bis an die Oberkante der Abdeckung reichend auszubilden, um dessen Stabilität zu vergrößern. Die an dem Längssteg anbringbaren Querstege können entweder nur bis nahe den Bürstwellen oder auch unterhalb derselben durchgehend bis zu den Unterkanten der Abdeckung reichend angeordnet sein.In the case of two or more cleaning brushes arranged in parallel with one another and driven in the direction of rotation, according to a further advantageous further development of the invention, the crosspieces can be attached to the cover on a cover which is located between the brushes, preferably below the intersection of the surface lines of the same Be arranged longitudinal web. It is also possible to increase the center distance of the two brushes and to extend the longitudinal web between the brushes, if necessary, to the top edge of the cover in order to increase its stability. The transverse webs which can be attached to the longitudinal web can either be arranged extending only as far as near the brush shafts or also underneath the brush shafts extending as far as the lower edges of the cover.

Sind in der Abdeckung zwei oder mehrere Bürsten parallel nebeneinander liegend angeordnet, so kann in einer besonders vorteilhaften Ausgestaltung der Erfindung vorgesehen sein, daß die Querstege einer Bürstseite gegenüber jener der anderen Bürstseite etwa um den halben Durchmesser eines Borstenbüschels versetzt angeordnet sind. Da zusammenhängend damit auch die Borstenbüschel beider Bürsten um diesen Abstand zu versetzen sind, ergibt sich dadurch an der gesamten Länge der Bürstabdeckung eine lückenlose Anordnung von Borstenbüscheln, die eine wirksame Reinigung des Gegenstandes in einem Arbeitsgang ermöglicht.If two or more brushes are arranged parallel to one another in the cover, it can be provided in a particularly advantageous embodiment of the invention that the transverse webs of one brush side are offset with respect to that of the other brush side by about half the diameter of a tuft of bristles. Since the bristle tufts of both brushes are to be offset by this distance in connection therewith, this results in a complete arrangement of bristle tufts over the entire length of the brush cover, which enables effective cleaning of the object in one operation.

Die Erfindung wird anhand einiger Ausführungsbeispiele näher erläutert: Es zeigen: Fig. 1 u. 2 je eine Bürstabdeckung nach der Erfindung mit einer in dieser angeordneten Reinigungsbürste, Fig. 3 u. 4 ebenfalls im Querschnitt je eine weitere Ausbildung der erfindungsgemäßen Abdeckung mit zwei parallel nebeneinander liegenden in diesen angeordneten Reinigungsbürsten und Fig. 5 einen Schnitt gemäß der Linie I-I in Fig. 4.The invention is explained in more detail with the aid of a few exemplary embodiments: FIG. 1 and FIG. 2 each a brush cover according to the invention with a cleaning brush arranged in this, Fig. 3 u. 4, also in cross-section, each a further embodiment of the cover according to the invention with two cleaning brushes arranged in parallel next to each other, and FIG. 5 a section along the line I-I in FIG. 4.

In dem erfindungsgemäßen Beispiel in Fig. 1 ist die Reinigungsbürste 1, die aus der Bürstwelle 2 und den Borstenbüscheln 3 besteht, von der Abdeckung 4 umgeben, welche in einen Absaugkanal 5 einer staubabsaugenden Einrichtung mündet. An der nach aufwärts gerichteten Drehseite der Bürste 1. sind in Längsrichtung derselben in einigen Abständen zwischen den Borstenbüscheln 3 quer liegende Stege 6, die mit der Abdeckung 4 verbunden sind, bis knapp an die Bürstachse 2 reichend angeordnet.In the example according to the invention in FIG. 1, the cleaning brush 1, which consists of the brush shaft 2 and the bristle tufts 3, is surrounded by the cover 4, which opens into a suction channel 5 of a dust-extracting device. On the upward rotating side of the brush 1 stood between the bristle tufts 3 transverse webs 6, which are connected to the cover 4, arranged just up to the brush axis 2 reaching.

Die Fig. 2 zeigt eine von der Abdeckung 4 umschlossene Reinigungsbürste 1, bei welcher die Querstege 6 unter der Bürstwelle 2 durchgehend über die gesamte Breite der offenen Abdeckung 4 angeordnet sind. Um das Auswechseln der Reinigungsbürste 1 zu ermöglichen, - sofern diese an der Vorrichtung nicht selbst austauschbar gelagert ist - ist die mit den Querstegen 6 verbundene Abdeckung 4 in dem Gehäuse 10 der Vorrichtung, in welcher der Absaugkanal 5 angeordnet ist, einsetzbar. Die Abdeckung 4 wird demnach über die Bürste 1 geschoben und ist daher an ihrer 0berseite in einer Breite, die etwa dem Bürstdurchmesser entspricht, geöffnet. Die Abdeckung 4 rastet in Einkerbungen des Gehäuses 10 ein und ist durch Eigenspannung in demselben haltbar.FIG. 2 shows a cleaning brush 1 enclosed by the cover 4, in which the transverse webs 6 are arranged under the brush shaft 2 continuously over the entire width of the open cover 4. In order to make it possible to replace the cleaning brush 1, provided that it is not interchangeably mounted on the device itself, the cover 4 connected to the crossbars 6 can be used in the housing 10 of the device in which the suction channel 5 is arranged. The cover 4 is therefore pushed over the brush 1 and is therefore open on its upper side in a width which corresponds approximately to the brush diameter. The cover 4 snaps into notches in the housing 10 and can be held in it by internal stress.

In Fig. 3, die eine Bürstanordnung mit zwei parallel nebeneinander liegenden, mit nach innen gerichteter Drehbewegung angetriebenen Reinigungsbürsten zeigt, sind die querliegenden und jeweils bis zu den Bürstwellen 2 reichenden Querstege an einem unter dem Schnittpunkt der Mantellinien der Bürsten 1 u. 1' anbringbaren Längssteg 7 angeordnet. Der mit den Querstegen verbundene Längssteg kann einstückig mit der Abdeckung gefertigt sein oder mit Hilfe von Federklammern o. dgl. in diese einsetzbar abgeordnet werden.In Fig. 3, which shows a brush arrangement with two parallel side by side, driven with an inward rotating cleaning brushes, the transverse and each reaching to the brush shafts 2 crosspieces are at a below the intersection of the surface lines of the brushes 1 and. 1 'attachable longitudinal web 7 arranged. The longitudinal web connected to the transverse webs can be made in one piece with the cover or can be inserted into it with the aid of spring clips or the like.

Die Fig. 4 zeigt wiederum die Anordnung von zwei parallel nebeneinander liegenden Reinigungsbürsten in einer erfindungsgemäß ausgebildeten Bürstabdeckung. Bei dieser sind die Querstege 6, die in der Mitte einen zur Versteifung dienenden Längssteg 11 aufweisen, mit Längsstegen 12 uj 13 verbunden, welche in Längsrichtung der Bürsten 1 u. 1' beiderseits nach oben hin mit nach innen gewölbten Laschen ausgebildet sind. Die mit den Längsstegen 12 u. 13 verbundenen Laschen rasten in Ausnehmungen der Abdeckung 4 ein, sodaß dadurch eine leicht austauschbare Anbringung der Querstege 6 in der Abdeckung 4 möglich ist.4 in turn shows the arrangement of two cleaning brushes lying next to one another in parallel in a brush cover designed according to the invention. In this, the transverse webs 6, which have a stiffening longitudinal web 11 in the middle, are connected to longitudinal webs 12 and 13, which in the longitudinal direction of the brushes 1 u. 1 'are formed on both sides upwards with inwardly curved tabs. The with the longitudinal webs 12 u. 13 connected tabs snap into recesses in the cover 4, so that an easily replaceable attachment of the crossbars 6 in the cover 4 is possible.

In der Fig. 5 ist beispielsweise die-Anordnung der Querstege 6 entlang der Bürsten 1 u. 1' dargestellt. Die Querstege einer Bürste und somit auch die Borstenbüschel derselben sind dabei gegenüber jenen der anderen Bürste etwa um den halben Durchmesser eines Borstenbüschels versetzt angeordnet, sodaß trotz der Querstege eine lückenlose Anordnung von Borstenbüscheln in der gesamten Bürstlänge möglich ist. In diesem Ausführungsbeispiel ist zwischen zwei nebeneinander liegenden Borstenbüscheln 3 je ein Quersteg 6 vorgesehen. Die Anzahl der erforderlichen Querstege 6 ist je nach Bürstanordnung und Bürstausbildung verschieden; auch die Ausbildung der Abdeckung 4 kann ausschlaggebend für die Zahl der notwendigen Querstege sein, um damit die erfindungsgemäßen Vorteile zu erzielen. Eine Kombination der verschiedenen Ausführungen untereinander ist möglich. Die möglichen Anordnungen beschränken sich daher keineswegs auf die dargestellten Ausführungsbeispiele; so können beispielsweise die-Querstege 6 in verschiedenen Abständen voneinander angeordnet oder auch mit unterschiedlichen Längen bzw. Querschnitten ausgebildet sein.5, for example, the arrangement of the crosspieces 6 along the brushes 1 u. 1 'shown. The crosspieces of a brush and thus also the tufts of bristles are offset from those of the other brush by about half the diameter of a tufts of bristles, so that despite the crosspieces, an uninterrupted arrangement of tufts of bristles is possible along the entire length of the brush. In this embodiment, a transverse web 6 is provided between two bristle tufts 3 lying next to one another. The number of crossbars 6 required varies depending on the brush arrangement and brush training; the design of the cover 4 can also be decisive for the number of crossbars required in order to achieve the advantages according to the invention. A combination of the different designs is possible. The possible arrangements are therefore in no way limited to the exemplary embodiments shown; for example, the transverse webs 6 can be arranged at different distances from one another or can also be designed with different lengths or cross sections.

Die Erfindung ist daher für die verschiedensten Bürstausbildungen und Bürstanordnungen anwendbar. Der Einfachheit halber sind in den Ausführungsbeispielen die Borstenbüschel parallel zur Längsachse der Bürste dargestellt, obwohl üblicherweise schraubenförmig o. dgl. an der Bürstwelle verlaufende Bürstbüschelanordnungen bevorzugt verwendet werden. Die erfindungsgemäße Bürstanordnung ist auch für zwei oder mehrere parallel nebeneinander in der Vorrichtung oder in der Abdeckung gelagerte Reinigungsbürsten vorteilbringend anwendbare selbst dann, wenn die Borstenbüschel beider Bürsten ineinander greifend angeordnet sind.The invention is therefore applicable to a wide variety of brush designs and brush arrangements. For the sake of simplicity, the bristle tufts are shown parallel to the longitudinal axis of the brush in the exemplary embodiments, although usually brush tufts arranged on the brush shaft in a helical or the like manner are preferably used.
