Description

KEHRGERAT KEHRGERAT
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 a brush roller mounted in a housing, a dirt collecting container that can be detachably connected to the housing and with a dirt inlet opening in the dirt collecting container adjacent to the brush roller, on the lower edge of which a 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 to separate the dirt collection container for emptying from the housing and then to transport it to an emptying point. These 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.When transported to the emptying point, there is a risk that dirt collected in the dirt collecting container will escape from the interior. In order to prevent this, it is also known to provide a threshold at the bottom of the dirt collecting container in the area of the dirt inlet opening, via which the dirt particles are thrown away during operation of the sweeper. However, such a threshold prevents dirt particles collected at the bottom of the dirt collecting container from falling out of the interior during transport to the emptying point.
Schmutzsammelbehälter werden häufig als Kunststoffbehälter ausgebildet, und dabei ist es schwierig, derartige Schwellen an das Bodenteil anzuformen, insbeson- dere ergeben sich dabei Ausformprobleme bei der Herstellung.Dirt collecting containers are often designed as plastic containers, and it is difficult to form such thresholds on the base part, in particular This gives rise to molding problems during manufacture.
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.It is an object of the invention to design a generic sweeper so that the threshold on the lower edge of the dirt collecting container can be manufactured in a particularly simple manner.
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 object is achieved according to the invention in a sweeper of the type described in the introduction in that the threshold is formed from a wall section which runs along its two longitudinal edges in a plane and projects in between on one side from this plane, and in that the wall section along its longitudinal edges with is connected to the bottom of the dirt container, wherein there is a two-piece connection between the bottom and the wall section at least along one longitudinal edge.
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 is thus formed to protrude on one side, for example by means of an arcuate or an angled cross section, and this wall section is connected to the bottom of the dirt collecting container. The connection along both longitudinal edges can be in two parts, that is to say the wall section independent of the dirt collecting container and the bottom of the dirt collecting container are connected to one another in the connection region, 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 Verbin- düng 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.However, it is also possible for such a two-piece connection to be made only along one longitudinal edge, while a one-piece connection is made along the other longitudinal edge. fertilizer between the floor and the wall section. In this case, the wall section is formed in one piece with the floor when the dirt collecting container is formed and is then positioned by bending the wall section relative to the floor in the manner in which the threshold is ultimately to be arranged. Normally this will be a pivoting movement, this can be simplified in particular in that the one-piece connection is designed as a hinge connection, 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.In this embodiment, the free longitudinal edge is then connected to the floor in a suitable manner, either by means of a mechanical snap-in connection, whether by 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 is particularly advantageous in which it is provided that the two-piece connection of the bottom and the longitudinal edge of the wall section can be produced by engaging a projection in a recess.
Der Rücksprung kann beispielsweise durch eine Längsnut im Boden gebildet werden, in die die Längskante des Wandabschnitts eingreift.The recess can be formed, for example, by a longitudinal groove in the bottom, 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 is formed by a step in the floor, the upper edge of which projects over its lower edge.
Insbesondere kann die Längsnut im Querschnitt V-förmig ausgebildet sein. 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.In particular, the longitudinal groove can have a V-shaped cross section. It is also advantageous if the wall section is wedge-shaped in cross-section along its longitudinal edge engaging in the longitudinal groove, thereby facilitating the insertion of the longitudinal edge into the longitudinal groove.
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 it is provided that the connections of the longitudinal edges to the floor lie so closely together that the wall section is bulged elastically and the longitudinal edges are therefore subjected to a tensioning force which moves them away from each other. This ensures that a free edge of the wall section engaging in a longitudinal groove is held; it can only be pulled out of the longitudinal groove against the elastic tensioning force which separates the longitudinal edges from one another.
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 planar wall surfaces connected at an angle to one another, the connecting edge of which runs parallel to its longitudinal edges.
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 favorable if the threshold partially dips into a complementary recess of the housing when the dirt collecting container is connected to the housing, this leads to a particularly good fixing of the dirt collecting container to the housing and also serves as an insertion aid. The complementary recess in the housing can be designed as a one-sided open, cross-sectionally V-shaped sleeper or ramp, which is directly adjacent to a rotating brush roller and thus as Guide surface for the dirt particles thrown off the brush roller.
Die nachfolgende Beschreibung einer bevorzugten Ausfüh- rungsform der Erfindung dient im Zusammenhang mit der Zeichnung der näheren Erläuterung. Es zeigen:The following description of a preferred embodiment of the invention serves in conjunction with the drawing for a more detailed explanation. Show it:

Figur 4: eine Ansicht ähnlich Figur 3 nach Ausbildung einer Schwelle.Figure 4 is a view similar to Figure 3 after the formation of a threshold.
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 3 zugewandten Stirnseite 7 offen ist und somit eine Schmutzeintrittsöffnung ausbildet. 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 sweeper 1 shown in the drawing comprises a housing 2 in which a brush roller 3 is rotatably mounted, which can be set in rotation by a drive 4 via a belt 5. The housing 2 is connected to a box-shaped dirt collecting container 6, which is open on its end face 7 facing the housing 3 and thus forms a dirt inlet opening. The open end face 7 is connected to a likewise open end face 8 of the housing 2 facing the dirt collecting container 6, so in this area there is a passage from the inside of 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 collecting container 6 carry rollers 9, 10, so that the sweeper 1 can be moved on a surface 11 to be cleaned, for example with the aid of a handle 12 pivotably mounted on the upper side of the housing 2 4 rotated brush roller 3, which emerges downward from the housing 2 and rests against the surface 11, dirt particles lying on this surface 11 away from the surface 11 and conveys them into the interior of 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 after the brush roller 3, a rising ramp 13 is arranged in the housing 2, which delimits the open end face 8 of the housing on the underside and which forms a guide surface for the dirt particles thrown off by the brush roller 3, these are via the ramp 13 into the interior of the dirt collector 6 flung.
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 there is a threshold 15 which delimits the open end face 7 on the underside, which extends over the entire width of the dirt inlet opening of the dirt collecting container 6 and which is formed by a wall section 16 with two flat, along one edge 19 at an obtuse angle to one another adjoining wall surfaces 17, 18. The two wall surfaces 17 and 18 end in longitudinal edges 20 and 21, which run parallel to one another and parallel to the edge 19 and which span a plane from which the wall surfaces 17, 18 protrude on one side.
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 integrally connected along a longitudinal edge 20 to the end edge 22 of the bottom 14, thus forming an extension of this bottom 14. The connection is designed in the manner of a film hinge, that is, by a material thinning 23 a bendable area in the transition between the Bottom 14 on the one hand and the wall section 16 on the other hand 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 ) .At a distance from the end edge 22, the bottom 14 has a step 24 running parallel to it, whose upper edge 25 projects beyond the lower edge 26, so that a longitudinal groove 27 with a V-shaped cross section is created (FIG. 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 is pivoted upward about the terminating edge 22, engagement of the longitudinal edge 21 in the longitudinal groove 27 can only be achieved in that the wall surfaces 17th and 18 of the wall section 16 can be pivoted elastically against one another, so that the angle between the two wall surfaces 17, 18 is reduced. This results in an elastic deformation of the wall section 16, as soon as the longitudinal edge 21 enters the longitudinal groove 27, the wall section 16 relaxes again, so that the longitudinal edge 21 is then under tension is held in the longitudinal groove 27. A particularly good engagement of the longitudinal edge 21 in the V-shaped longitudinal groove 27 results from the fact that the wall surface 18 is tapered in a wedge shape in the region of the longitudinal edge 21, that is to say it is essentially complementary to the cross section of the longitudinal groove 27.
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 is possible to form a threshold on the top of the floor 14 through the wall section 16 integrally formed on the bottom 14 of the dirt collecting container 6, it is sufficient to pivot the molded wall section 16 upwards and to insert the longitudinal edge 21 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 2 wird dadurch praktisch Teil der Rampe 13. The threshold 15 formed in this way plunges into the V-shaped recess 28 in the ramp 13 when the dirt collecting container 6 is connected to the housing 2, so that an exact guidance of the dirt collecting container relative to the housing 2 can be achieved, the threshold 2 thereby becoming a practical part the ramp 13.
