Description

Die Erfindung betrifft ein Kehrgerät mit einer in einem Gehäuse gelagerten Bürstenwalze, einem mit dem Gehäuse lösbar verbindbaren Schmutzsammelbehälter und mit einer der Bürstenwalze benachbarten Schmutzeintrittsöffnung im Schmutzsammelbehälter, an deren Unterkante eine Schwelle angeordnet ist.The invention relates to a sweeper with one in one Brush roller mounted on the housing, one with the housing detachably connectable dirt collection container and with a the dirt inlet opening adjacent to the brush roller in the dirt collecting container, one on the lower edge Threshold is arranged.

Bei Kehrgeräten ist es bekannt, die Schmutzsammelbehälter zur Entleerung vom Gehäuse zu trennen und dann an eine Entleerungsstelle zu transportieren. Diese Schmutzsammelbehälter sind meistens einseitig offen, die offene Seite bildet die Schmutzeintrittsöffnung in den Sammelbehälter.In sweepers, it is known, the dirt collector to separate from the housing for emptying and then on to transport an emptying point. This Dirt collection containers are usually open on one side, the open side forms the dirt inlet opening in the collection container.

Beim Transport an die Entleerungsstelle ergibt sich dabei die Gefahr, daß im Schmutzsammelbehälter gesammelter Schmutz aus dem Innenraum austritt. Um dies zu verhindern, ist es weiterhin bekannt, am Boden des Schmutzsammelbehälters im Bereich der Schmutzeintrittsöffnung eine Schwelle vorzusehen, über die die Schmutzteilchen beim Betrieb des Kehrgeräts hinweggeschleudert werden. Eine solche Schwelle verhindert jedoch, daß am Boden des Schmutzsammelbehälters gesammelte Schmutzteilchen beim Transport zur Entleerungsstelle aus dem Innenraum herausfallen.This results in the transport to the emptying point the risk of collecting in the dirt container Dirt escapes from the interior. To prevent this, it is still known at the bottom of the Dirt collecting container in the area of the dirt inlet opening to provide a threshold over which the dirt particles flung away while operating the sweeper become. However, such a threshold prevents Dirt particles collected in the bottom of the dirt collecting container during transport to the emptying point from the Interior fall out.

Schmutzsammelbehälter werden häufig als Kunststoffbehälter ausgebildet, und dabei ist es schwierig, derartige Schwellen an das Bodenteil anzuformen, insbesondere ergeben sich dabei Ausformprobleme bei der Herstellung. Ein solcher Schmutzsammelbehälter ist beispielsweise aus der DE 196 01 976 A1 bekannt. Die Schwelle wird dort durch eine Stufe im Boden des Schmutzsammelbehälters gebildet, und derartige Stufen führen zu einem relativ komplizierten Herstellungsverfahren.Dirt collection containers are often called plastic containers trained, and it is difficult to find such To mold sleepers to the bottom part, in particular Forming problems arise during manufacture. Such a dirt collector is, for example known from DE 196 01 976 A1. The There is a step in the floor of the threshold Dirt collector, and such stages lead to a relatively complicated manufacturing process.

Es ist Aufgabe der Erfindung, ein gattungsgemäßes Kehrgerät so auszugestalten, daß die Schwelle an der Unterkante des Schmutzsammelbehälters in besonders einfacher Weise hergestellt werden kann.The object of the invention is a generic sweeper To be designed so that the threshold at the bottom edge of the dirt collecting container in a particularly simple manner Way can be made.

Diese Aufgabe wird bei einem Kehrgerät der eingangs beschriebenen Art erfindungsgemäß dadurch gelöst, daß die Schwelle aus einem Wandabschnitt gebildet wird, der längs seiner beiden Längskanten in einer Ebene verläuft und dazwischen nach einer Seite aus dieser Ebene hervorsteht, und daß der Wandabschnitt längs seiner Längskanten mit dem Boden des Schmutzbehälters verbunden ist, wobei mindestens längs einer Längskante eine zweistückige Verbindung zwischen dem Boden und dem Wandabschnitt besteht.This task is described in a sweeper of the beginning Art solved according to the invention in that the Threshold is formed from a wall section that runs in one plane along its two longitudinal edges and protrudes from this level to one side in between, and that the wall section along its longitudinal edges connected to the bottom of the dirt container is, at least along a longitudinal edge a two-piece Connection between the floor and the wall section consists.

Es wird also ein Wandabschnitt einseitig hervorstehend ausgebildet, beispielsweise durch einen bogenförmigen oder einen abgewinkelten Querschnitt, und dieser Wandabschnitt wird mit dem Boden des Schmutzsammelbehälters verbunden. Dabei kann die Verbindung längs beider Längskanten zweistückig sein, das heißt, es werden im Verbindungsbereich der vom Schmutzsammelbehälter unabhängige Wandabschnitt und der Boden des Schmutzsammelbehälters miteinander verbunden, beispielsweise durch eine Verrastung oder eine Verklebung.A wall section thus protrudes on one side formed, for example by an arcuate or an angled cross-section, and this wall section comes with the bottom of the dirt collector connected. The connection can be along both Longitudinal edges must be in two pieces, that is, it will be in Connection area that is independent of the dirt collection container Wall section and the bottom of the dirt container connected to each other, for example by a latching or gluing.

Es ist aber auch möglich, daß eine solche zweistückige Verbindung nur längs einer Längskante erfolgt, während längs der anderen Längskante eine einstückige Verbindung zwischen dem Boden und dem Wandabschnitt vorliegt. In diesem Falle wird der Wandabschnitt beim Formen des Schmutzsammelbehälters einstückig mit dem Boden ausgebildet und wird dann durch Abbiegen des Wandabschnitts gegenüber dem Boden so positioniert, wie die Schwelle letztendlich angeordnet werden soll. Normalerweise wird dies eine Verschwenkbewegung sein, diese kann insbesondere dadurch vereinfacht werden, daß die einstückige Verbindung als Scharnierverbindung ausgebildet ist, also beispielsweise als sogenanntes Filmscharnier.But it is also possible that such a two-part Connection only takes place along one longitudinal edge, while a one-piece connection along the other longitudinal edge between the floor and the wall section. In this case, the wall section when molding the Dirt collecting container formed in one piece with the bottom and then by bending the wall section positioned opposite the floor as the threshold ultimately to be ordered. Usually it will this can be a pivoting movement, this can in particular be simplified in that the one-piece Connection is designed as a hinge connection, that is for example as a so-called film hinge.

Die freie Längskante wird bei dieser Ausgestaltung dann in geeigneter Weise mit dem Boden verbunden, sei es durch eine mechanische Rastverbindung, sei es durch eine Verklebung oder Verschweißung.The free longitudinal edge is then in this embodiment appropriately connected to the ground, be it by a mechanical locking connection, be it by a Gluing or welding.

Besonders vorteilhaft ist eine Ausgestaltung, bei der vorgesehen ist, daß die zweistückige Verbindung des Bodens und der Längskante des Wandabschnitts durch ein Eingreifen eines Vorsprungs in einen Rücksprung herstellbar ist.An embodiment in which it is provided that the two-piece connection of the Bottom and the longitudinal edge of the wall section through a Intervention of a projection in a recess can be produced is.

Der Rücksprung kann beispielsweise durch eine Längsnut im Boden gebildet werden, in die die Längskante des Wandabschnitts eingreift.The recess can be through a longitudinal groove, for example be formed in the ground, in which the longitudinal edge of the Wall section engages.

Dabei ist es vorteilhaft, wenn die Längsnut von einer Stufe im Boden gebildet wird, deren obere Kante gegenüber ihrer unteren Kante vorspringt.It is advantageous if the longitudinal groove of one Step is formed in the bottom, the top edge opposite protrudes from its lower edge.

Insbesondere kann die Längsnut im Querschnitt V-förmig ausgebildet sein. In particular, the longitudinal groove can be V-shaped in cross section be trained.

Es ist weiterhin vorteilhaft, wenn der Wandabschnitt längs seiner in die Längsnut eingreifenden Längskante im Querschnitt keilförmig ausgebildet ist, dadurch wird das Einschieben der Längskante in die Längsnut erleichtert.It is also advantageous if the wall section along its longitudinal edge engaging in the longitudinal groove is wedge-shaped in cross section, thereby the insertion of the longitudinal edge into the longitudinal groove easier.

Bei einer bevorzugten Ausführungsform ist vorgesehen, daß die Verbindungen der Längskanten mit dem Boden so dicht beieinanderliegen, daß der Wandabschnitt elastisch aufgewölbt wird und die Längskanten daher mit einer sie voneinander entfernenden Spannkraft beaufschlagt sind. Dies stellt sicher, daß eine in eine Längsnut eingreifende freie Kante des Wandabschnitts gehalten wird, sie kann nur gegen die elastische Spannkraft, die die Längskanten voneinander entfernt, aus der Längsnut herausgezogen werden.In a preferred embodiment, that the connections of the longitudinal edges to the ground so lie close together that the wall section is elastic is bulged and therefore the longitudinal edges a clamping force that removes them from each other are. This ensures that one in one Long edge engaging free edge of the wall section is held, it can only against the elastic tension, which separate the long edges from each other the longitudinal groove are pulled out.

Insbesondere kann der Wandabschnitt aus zwei winklig miteinander verbundenen ebenen Wandflächen bestehen, deren Verbindungskante parallel zu seinen Längskanten verläuft.In particular, the wall section can consist of two angles interconnected flat wall surfaces exist, the connecting edge parallel to its longitudinal edges runs.

Es ist günstig, wenn die Schwelle bei mit dem Gehäuse verbundenem Schmutzsammelbehälter teilweise in eine komplementäre Ausnehmung des Gehäuses eintaucht, dies führt zu einer besonders guten Festlegung des Schmutzsammelbehälters am Gehäuse und dient auch als Einführhilfe. Die komplementäre Ausnehmung im Gehäuse kann als einseitig offene, im Querschnitt V-förmige Schwelle oder Rampe ausgeführt sein, die unmittelbar einer rotierenden Bürstenwalze benachbart ist und die damit als Leitfläche für die von der Bürstenwalze abgeschleuderten Schmutzteilchen dient.It is convenient if the threshold is with the case connected dirt collection container partially in a complementary recess of the housing dips this leads to a particularly good definition of the dirt collecting container on the housing and also serves as an insertion aid. The complementary recess in the housing can be as one-sided open, cross-sectionally V-shaped threshold or ramp that are immediately rotating Brush roller is adjacent and thus as Guide surface for those thrown off the brush roller Debris serves.

Das in der Zeichnung dargestellte Kehrgerät 1 umfaßt ein Gehäuse 2, in dem eine Bürstenwalze 3 drehbar gelagert ist, die von einem Antrieb 4 über einen Riemen 5 in Drehung versetzt werden kann. Das Gehäuse 2 ist mit einem kastenförmigen Schmutzsammelbehälter 6 verbunden, der auf seiner dem Gehäuse 2 zugewandten Stirnseite 7 offen ist und somit eine Schmutzeintrittsöffnung ausbildet. The sweeper 1 shown in the drawing includes a housing 2 in which a brush roller 3 rotatably mounted is that of a drive 4 via a belt 5th can be rotated. The housing 2 is with connected to a box-shaped dirt collecting container 6, on its end face 7 facing the housing 2 is open and thus forms a dirt inlet opening.

Die offene Stirnseite 7 steht mit einer ebenfalls offenen, dem Schmutzsammelbehälter 6 zugewandten Stirnseite 8 des Gehäuses 2 in Verbindung, in diesem Bereich ergibt sich also ein Durchtritt aus dem Inneren des Gehäuses 2 in das Innere des Schmutzsammelbehälters 6.The open end face 7 is also open, the dirt collecting container 6 facing end face 8 of the housing 2 in connection, results in this area there is a passage from inside the housing 2 into the inside of the dirt collecting container 6.

Sowohl das Gehäuse 2 als auch der Schmutzsammelbehälter 6 tragen Rollen 9, 10, so daß das Kehrgerät 1 auf einer zu reinigenden Fläche 11 verfahrbar ist, beispielsweise mit Hilfe eines an der Oberseite des Gehäuses 2 verschwenkbar gelagerten Handgriffs 12. Dabei kehrt die durch den Antrieb 4 in Drehung versetzte Bürstenwalze 3, die nach unten aus dem Gehäuse 2 austritt und an der Fläche 11 anliegt, auf dieser Fläche 11 liegende Schmutzteilchen von der Fläche 11 weg und befördert sie in das Innere des Gehäuses 2.Both the housing 2 and the dirt collector 6 carry rollers 9, 10 so that the sweeper 1 on a surface 11 to be cleaned is movable, for example with the help of a pivotable on the top of the housing 2 stored handle 12. This returns the brush roller set in rotation by the drive 4 3, which emerges downwards from the housing 2 and on the Surface 11 rests, lying on this surface 11 Debris away from surface 11 and conveys it inside the housing 2.

Unmittelbar anschließend an die Bürstenwalze 3 ist im Gehäuse 2 eine ansteigende Rampe 13 angeordnet, die die offene Stirnseite 8 des Gehäuses an der Unterseite begrenzt und die eine Leitfläche für die von der Bürstenwalze 3 abgeschleuderten Schmutzteilchen bildet, diese werden über die Rampe 13 in den Innenraum des Schmutzsammelbehälters 6 geschleudert.Immediately following the brush roller 3 is in Housing 2 arranged a rising ramp 13 which the open front 8 of the housing limited at the bottom and the one guide surface for that of the brush roller 3 thrown off dirt particles, this are on the ramp 13 in the interior of the dirt collector 6 hurled.

Am Boden 14 des Schmutzsammelbehälters 6 befindet sich eine die offene Stirnseite 7 an der Unterseite begrenzende Schwelle 15, die sich über die gesamte Breite der Schmutzeintrittsöffnung des Schmutzsammelbehälters 6 erstreckt und die gebildet wird durch einen Wandabschnitt 16 mit zwei ebenen, längs einer Kante 19 stumpfwinklig aneinander anschließenden Wandflächen 17, 18. Die beiden Wandflächen 17 und 18 enden in Längskanten 20 beziehungsweise 21, die parallel zueinander und parallel zu der Kante 19 verlaufen und die eine Ebene aufspannen, aus der die Wandflächen 17, 18 einseitig abstehen.At the bottom 14 of the dirt collecting container 6 is located a the open end face 7 delimiting at the bottom Threshold 15, which extends across the entire width of the Dirt inlet opening of the dirt collecting container 6 extends and which is formed by a wall portion 16 with two planes along an edge 19 wall surfaces 17 adjoining each other at an obtuse angle, 18. The two wall surfaces 17 and 18 end in longitudinal edges 20 or 21, which are parallel to each other and run parallel to the edge 19 and the one plane span, from which the wall surfaces 17, 18 one-sided protrude.

Der Wandabschnitt 16 ist längs einer Längskante 20 einstückig mit der Abschlußkante 22 des Bodens 14 verbunden, bildet also eine Verlängerung dieses Bodens 14. Die Verbindung ist dabei nach Art eines Filmscharniers ausgebildet, das heißt durch eine Materialverdünnung 23 wird ein biegbarer Bereich im Übergang zwischen dem Boden 14 einerseits und dem Wandabschnitt 16 andererseits geschaffen.The wall section 16 is in one piece along a longitudinal edge 20 connected to the end edge 22 of the bottom 14, thus forms an extension of this bottom 14. The connection is like a film hinge formed, that is by a material thinning 23rd becomes a bendable area in the transition between the floor 14 on the one hand and the wall section 16 on the other created.

Der Boden 14 weist im Abstand zu der Abschlußkante 22 eine parallel zu dieser verlaufende Stufe 24 auf, deren obere Kante 25 über die untere Kante 26 vorspringt, so daß dadurch eine im Querschnitt V-förmige Längsnut 27 entsteht (Figur 3).The bottom 14 is at a distance from the end edge 22 a parallel to this level 24, whose protrudes upper edge 25 over the lower edge 26, so that thereby a V-shaped longitudinal groove 27th arises (Figure 3).

Die Abmessungen sind dabei so gewählt, daß die Längskante 21 in die Längsnut 27 eingreift, wenn der Wandabschnitt 16 um die Abschlußkante 22 nach oben geschwenkt wird, wobei ein Eingreifen der Längskante 21 in die Längsnut 27 nur dadurch zu erreichen ist, daß die Wandflächen 17 und 18 des Wandabschnitts 16 elastisch gegeneinander verschwenkt werden, daß also der Winkel zwischen den beiden Wandflächen 17, 18 verkleinert wird. Dadurch erfolgt eine elastische Verformung des Wandabschnitts 16, sobald die Längskante 21 in die Längsnut 27 eintritt, entspannt sich der Wandabschnitt 16 wieder, so daß dann die Längskante 21 unter Spannung in der Längsnut 27 gehalten wird. Ein besonders guter Eingriff der Längskante 21 in der V-förmigen Längsnut 27 ergibt sich dadurch, daß die Wandfläche 18 im Bereich der Längskante 21 keilförmig zugespitzt ist, also im wesentlichen komplementär zum Querschnitt der Längsnut 27 ausgebildet ist.The dimensions are chosen so that the longitudinal edge 21 engages in the longitudinal groove 27 when the wall section 16 pivoted upward about the end edge 22 is, an engagement of the longitudinal edge 21 in the Longitudinal groove 27 can only be achieved in that the wall surfaces 17 and 18 of the wall section 16 elastically against each other be pivoted so that the angle reduced between the two wall surfaces 17, 18 becomes. This results in an elastic deformation of the Wall section 16 as soon as the longitudinal edge 21 in the Longitudinal groove 27 occurs, the wall section relaxes 16 again, so that the longitudinal edge 21 is under tension is held in the longitudinal groove 27. A particularly good one Engagement of the longitudinal edge 21 in the V-shaped longitudinal groove 27 results from the fact that the wall surface 18 in the area the longitudinal edge 21 is tapered in a wedge shape, that is essentially complementary to the cross section of the longitudinal groove 27 is formed.

Auf diese Weise gelingt es, durch den einstückig an den Boden 14 des Schmutzsammelbehälters 6 angeformten Wandabschnitt 16 eine Schwelle auf der Oberseite des Bodens 14 auszubilden, es genügt dazu, den angeformten Wandabschnitt 16 nach oben zu schwenken und die Längskante 21 in die Längsnut 27 einzuführen.In this way it succeeds in integrating the Bottom 14 of the dirt collecting container 6 integrally formed wall section 16 a threshold on the top of the floor 14 form, it is sufficient to the molded wall portion 16 to pivot upwards and the longitudinal edge 21 insert into the longitudinal groove 27.

Die in dieser Weise ausgebildete Schwelle 15 taucht bei mit dem Gehäuse 2 verbundenem Schmutzsammelbehälter 6 in eine V-förmige Ausnehmung 28 in der Rampe 13 ein, so daß eine exakte Führung des Schmutzsammelbehälters relativ zum Gehäuse 2 erzielbar ist, die Schwelle 15 wird dadurch praktisch Teil der Rampe 13.The threshold 15 designed in this way is immersed dirt collecting container 6 connected to the housing 2 in a V-shaped recess 28 in the ramp 13, so that an exact guidance of the dirt collector relative to the housing 2 can be achieved, the threshold 15 thereby practically part of the ramp 13.
