Definitions
- the invention relates to a movable over the floor to be cleaned floor cleaning machine with a drive assembly for the method of floor cleaning machine and for driving various elements and units of floor cleaning machine, can be brought into contact with the ground, rotationally driven cleaning brush and with a at least one mechanically pivotable lifting arm content Erten container which is displaceable between an operating position in which it is in sealing engagement with the opening edge of a dirt passage opening with its opening edge, and a raised position from which it can be pivoted by releasing a holding connection in a discharge position, wherein the at least a Aushebearm part of a parallelogram linkage having a with its outer end at a distance from the articulation of the Aushebearms on the dirt container pivotally mounted on this parallel arm, the inner s end is articulated in the operating position and in the raised position of the dirt container at a machine-fixed point.
- Such floor cleaning machines are known in various forms, for example from the US 5,377,376 , and in them threw the rotary driven cleaning brush, which usually had the form of a sweeping roller, which extended transversely to the longitudinal center plane of the floor cleaning machine, the dirt collected from the ground along a Schmutzleitkanal to a dirt passage opening.
- the dirt container In the operating position of the dirt container this was arranged on the outside of the dirt passage opening with its opening edge sealingly fitting, so that the dirt received from the ground was collected in it.
- the dirt container was located on at least one lifting arm, which together with a parallel arm formed a parallelogram linkage, generally on each lateral end of the dirt container attack a parallelogram linkage.
- the Aushebearme were pivoted by means of at least one hydraulic cylinder or a electric linear actuator upwards so that the dirt container was moved from the operating position to a raised position, whereby he maintained its orientation in space due to the effect of the parallelogram. In the raised position, the operator could then move the floor cleaning machine so that the dirt container in the region of the opening of a container o.ä. was to be emptied into the dirt container.
- the operator had to manually release a holding connection which non-pivotally coupled the dirt container to the parallelogram linkage.
- this holding connection was released, the dirt container usually pivoted by gravity about its pivot points at the outer end of the Aushebearme so that the dirt contained in it fell out.
- a floor cleaning machine of the type mentioned is inventively designed such that the holding connection is formed by the connection of the parallel arm with the dirt container and the machine-fixed point that the dirt container is supported when lowering the Aushebearms with dissolved holding connection against pivoting with respect to the Aushebearm in order to restore the holding connection, and that the support of the dirt container is automatically rendered inoperative after restoration of the holding connection.
- the support of the dirt container is automatically rendered ineffective, so that the Parallelogrammgestfite or Parallelogrammgestfite the dirt container can shift back into the operating position in which the opening edge sealingly abuts the opening edge of the dirt passage opening.
- a particularly advantageous solution for effecting the support of the dirt container is to provide an abutting on a stop surface spring whose support effect is ineffective due to deformation due to the increasing force of the lowering parallelogram linkage.
- This spring which may be, for example, a leaf spring attached to the hopper, which cooperates with a stop surface provided on the Aushebearm holds the dirt container while in the emptying position until the holding connection is restored, ie the spring must only exert such a support effect that overcome the resistances be a return of the parallel arm and the restoration of the holding connection counteract.
- the first guide surface is provided on the dirt container and the rigid stop at a machine-fixed point. Furthermore, can connect to the first guide surface, a second guide surface, which limits the pivoting of the dirt container when the free-coming of the rigid stop of the first guide surface, so that there is no overshoot of the dirt container.
- the release of the holding connection can be effected in that the inner end of the parallel arm is released from the machine-fixed point.
- the inner end of the parallel arm can be performed in a guide slot.
- it is pivotally connected to the upper end of an auxiliary arm, the lower end pivotally connected to the floor cleaning machine connected is.
- the auxiliary arm is held unverschwenkbar in existing holding connection, so that its connection with the parallel arm forms the machine-fixed point for this, while the auxiliary arm for releasing the holding connection from this non-pivoting holder is releasable.
- the non-pivotal mounting of the auxiliary arm can be effected for example by engagement of a latch, which can move the operator to a release position, in this way to release the holding connection, thus causing the pivoting of the dirt container in the emptying position.
- the detent pawl in existing holding connection, for example, in positive engagement with a provided on the auxiliary arm locking surface.
- the in the FIGS. 1 to 8 shown floor cleaning machine has a common basic structure with a chassis 1, on the rear wheels 2 and a front wheel 6 are arranged.
- a driver's seat 5 is provided, which has a driver's seat 6 and the various operating elements for the operation of the floor cleaning machine.
- a rotating drivable sweeping roller 3 comes in operation in contact with the soil to be cleaned and is in FIG. 1 Turned clockwise so that it throws the dirt picked up.
- the dirt guide channel terminating at a lower inlet opening of an air guide housing in which a filter device, not shown, above which a removable cover is provided.
- This structure including one provided in the side wall of the air duct housing, not shown blower is in the older German patent application 103 24 825.0 described.
- a hood 7 for example, according to the in the parallel German patent application "floor cleaning machine” ( German Patent Application No. 103 42 454.7 ) described in the applicant and, as explained there, covers the engine compartment for an internal combustion engine, not shown, with the help of which, inter alia, the blower, the sweeping roller 3 and a hydraulic motor for driving are driven.
- the illustrated floor cleaning machine differs from that of the parallel older German patent application "floor cleaning machine” ( German Patent Application No. 103 42 454.7 ) of the applicant and in the older one German patent applications 103 24 825.0 and 103 24 826.9 described floor cleaning machines, which is hereby incorporated by reference, only in that the dirt container is shaped and supported differently.
- the floor cleaning machine shown has a trough-shaped dirt container 10, as is already common in such floor cleaning machines, which is supported on one side by a parallelogram linkage which acts on the outer lateral ends of the dirt container. In the figures, this is provided in the direction of travel on the left side. On the other side of the Schmutzbumblelters 10 attacks only one Aushebearm, as described below as part of the Parellelogrammgestfites.
- the parallelogram linkage includes a lifting arm 12 pivotally attached to the upper end of a support column 11 mounted on the chassis 1.
- This support column is shown only partially in different figures to illustrate the operation of the parallelogram linkage. In these cases, the upper end of the support column 11 'of the Aushebearms provided in the figures in the direction of travel on the right side can be seen in the figures.
- Aushebearms 12 is pivotally connected at 14 with the side wall of the dirt container 10.
- a plate 31 is attached to the side wall of the dirt container, which carries a functionally to be described in terms of its function, made of elastically deformable plastic or rubber stop 32 and a leaf spring 33 also to be described.
- Aushebearm 12 engages 26 pivotally engages the outer end of the piston of a hydraulic working cylinder 25 which is pivotally mounted on the chassis 1 and in a manner not shown by a hydraulic motor driven by the hydraulic pump hydraulic fluid can be supplied to the Aushebearm 12 from the operating position of the dirt container 10 according to FIG. 8 For example, in the position according to FIG. 1 to raise.
- the corresponding lowering movement depending on the design of the hydraulic cylinder, either alone by discharging hydraulic fluid or by pushing out the hydraulic fluid causing the lifting by supplying hydraulic fluid to a counter surface of the piston of the working cylinder can be effected.
- a parallel arm 15 is hinged at its outer end at 17 below the linkage 14 of the outer end of the Aushebearms 12 on the side wall of the dirt container 10.
- the inner end of the parallel arm 15 is pivotally connected at 16 to the upper end of an auxiliary arm 18.
- the auxiliary arm 18 is pivotally mounted at 19 at a housing fixed point, and it has a guide pin which engages in a guide slot in a housing-fixed guide plate 20, so that the guide pin is guided in the still to be described pivoting of the auxiliary arm 18 in the guide slot and the auxiliary arm 18 is supported.
- the auxiliary arm 18 carries at its upper end a projection 21 which in the operating position of the dirt container ( FIG. 8 ) behind a pawl 30 ( FIG. 6 ), which is seated in a pawl housing 29 fastened to a machine-fixed point and which can be actuated by means of an actuating lever 27, which is provided adjacent to the driver's seat 6 and can be actuated by the driver sitting there, via a Bowden cable 28 against spring force from the locking position FIG. 6 can be pulled down so as to release the projection 21 and thus to release the auxiliary arm 18 from its non-pivoting holder.
- FIG. 1 the floor cleaning machine is shown in a state in which the Aushebearm 12 of the ParallelogrammgestShes pivoted to a raised position and the dirt container 10 is positioned over a container C, in which the dirt container 10 is to be emptied.
- the ParallelogrammgestShe in operation ie the auxiliary arm 18 is held by the pawl 30 in its non-pivotal holder, and therefore the inner end of the parallel arm 15 of the Parallelogrammgestfites is connected to a machine-fixed point, ie a holding connection between pivot point 17 of the outer end of the parallel arm 15 and the machine-fixed point available.
- the operator pivots the operating lever 27 and thereby pulls down the pawl 30 by means of the Bowden cable 28, so that the projection 21 of the auxiliary arm 18 is released, the parallel arm 15 no longer supports the dirt container 10. Due to the position of the center of gravity of the dirt container 10, this therefore pivots about the pivot point 14 in the emptying position FIG. 2 so that it is emptied into the container C.
- the articulation point 17 of the parallel arm 15 has performed an arcuate movement about the articulation point 14 of the Aushebearms 12, and the inner end of the Parallel arm 15 is as in FIG. 2 can be seen, under pivoting of the auxiliary arm 18 has been displaced to its lower pivot point 19 clockwise to the right.
- FIGS. 9 to 11 is shown in partial representations another way of supporting the dirt container, in these figures for the same and each other functionally corresponding elements as in the FIGS. 1 to 8 same, but increased by 100 reference numerals have been used. Elements already described will not be described again unless it appears necessary for the understanding.
- the dirt container 110 on its side wall (and also on the opposite side wall) on a first guide surface 133, which serves the dirt container when lowering from the position accordingly FIG. 4 by means of a machine-fixed, rigid projection 134 support. If this lead on in FIG. 9 Left end of the first guide surface 133 comes to rest, it prevents in the context of the leaf spring 33 in the embodiment according to FIGS. 1 to 8 described that the linkage 117 of the outer end of the parallel arm 114 (in the figures) can shift counterclockwise about the linkage 114 of the outer end of the Aushebearms 112, whereby, as also in connection with the embodiment according to FIG FIGS.
- the inner end of the parallel arm 115 is guided in its locked position. During this displacement movement, the first guide surface 133 slides over the projection 134 until the locked position of the parallel arm 115 is reached. This is the case if, as in FIG. 10 indicated, the projection 134 has arrived at the rear or right end of the first guide surface 133. Since now, as described above, to the action of the parallelogram linkage of the articulation point 117 of the front end of the parallel arm 115 (in the figures) must be shifted in the counterclockwise direction about the pivot point 114 of the front end of Aushebearms 112 comes on continuation of the lowering movement of the projection 134 of the first guide surface 133 free.
Description
Die Erfindung bezieht sich auf eine über den zu reinigenden Boden verfahrbare Bodenreinigungsmaschine mit einer Antriebsanordnung für das Verfahren der Bodenreinigungsmaschine und für den Antrieb verschiedener Elemente und Baueinheiten der Bodenreinigungsmaschine, mit einer in Berührung mit dem Boden bringbaren, drehend antreibbaren Reinigungsbürste und mit einem an mindestens einem maschinell verschwenkbaren Aushebearm gehalterten Schmutzbehälter, der zwischen einer Betriebsstellung, in der er mit seinem Öffnungsrand in dichtendem Eingriff mit dem Öffnungsrand einer Schmutzdurchtrittsöffnung steht, und einer angehobenen Stellung verlagerbar ist, aus der er durch Lösen einer Halteverbindung in eine Entleerungslage verschwenkbar ist, wobei der mindestens eine Aushebearm Teil eines Parallelogrammgestänges ist, das einen mit seinem äußeren Ende im Abstand von der Anlenkung des Aushebearms am Schmutzbehälter schwenkbar an diesem befestigten Parallelarm aufweist, dessen inneres Ende in der Betriebsstellung und in der angehobenen Stellung des Schmutzbehälters an einem maschinenfesten Punkt angelenkt ist.The invention relates to a movable over the floor to be cleaned floor cleaning machine with a drive assembly for the method of floor cleaning machine and for driving various elements and units of floor cleaning machine, can be brought into contact with the ground, rotationally driven cleaning brush and with a at least one mechanically pivotable lifting arm content Erten container which is displaceable between an operating position in which it is in sealing engagement with the opening edge of a dirt passage opening with its opening edge, and a raised position from which it can be pivoted by releasing a holding connection in a discharge position, wherein the at least a Aushebearm part of a parallelogram linkage having a with its outer end at a distance from the articulation of the Aushebearms on the dirt container pivotally mounted on this parallel arm, the inner s end is articulated in the operating position and in the raised position of the dirt container at a machine-fixed point.
Derartige Bodenreinigungsmaschinen sind in unterschiedlichen Formen bekannt, beispielsweise aus der
Um die Entleerung des Schmutzbehälters zu bewirken, musste die Bedienungsperson von Hand eine Halteverbindung lösen, die den Schmutzbehälter mit den Parallelogrammgestängen unverschwenkbar koppelte. Wenn diese Halteverbindung gelöst war, verschwenkte der Schmutzbehälter üblicherweise infolge Schwerkraft um seine Anlenkpunkte am äußeren Ende der Aushebearme, so dass der in ihm enthaltene Schmutz herausfiel.In order to effect the emptying of the dirt container, the operator had to manually release a holding connection which non-pivotally coupled the dirt container to the parallelogram linkage. When this holding connection was released, the dirt container usually pivoted by gravity about its pivot points at the outer end of the Aushebearme so that the dirt contained in it fell out.
Nach dem Entleeren war es erforderlich, den Schmutzbehälter von Hand in seine Ausgangsstellung bezüglich dem Parallelogrammgestänge zurückzuschwenken und die Halteverbindung wieder herzustellen. Es war allerdings auch bereits bekannt, im Bereich eines seitlichen Endes des Schmutzbehälters einen hydraulischen Arbeitszylinder oder einen elektrischen Linearantrieb vorzusehen, der bei Aktivierung den Schmutzbehälter aus der Entleerungsstellung in die übliche Ausrichtung bezüglich dem Parallelogrammgestänge zurückschwenkte, so dass dann die Halteverbindung wiederhergestellt werden konnte.After emptying, it was necessary to return the dirt container by hand to its original position with respect to the parallelogram linkage and restore the retaining connection. However, it was also already known to provide a hydraulic cylinder or an electric linear drive in the region of a lateral end of the dirt container, which pivoted back when activated the dirt container from the emptying position in the usual orientation with respect to the Parallelogrammgestänge, so that then the holding connection could be restored.
Bei den bekannten Lösungen war es somit erforderlich, die Rückschwenkung des Schmutzbehälters aus der Entleerungsstellung von Hand vorzunehmen, wozu die Bedienungsperson von der Bodenreinigungsmaschine heruntersteigen und mit erheblichem Kraftaufwand die Verschwenkbewegung des Schmutzbehälters vornehmen musste, oder es wurde ein zusätzlicher Antrieb für das maschinelle Zurückschwenken des Schmutzbehälters aus der Entleerungsstellung vorgesehen.In the known solutions, it was thus necessary to make the return pivoting of the dirt container from the emptying position by hand, for which the operator descend from the floor cleaning machine and with considerable effort had to make the pivoting movement of the dirt container, or it was provided an additional drive for the mechanical pivoting back of the dirt container from the emptying position.
Es ist Aufgabe der Erfindung, eine Bodenreinigungsmaschine so zu verbessern, dass das Zurückschwenken des Schmutzbehälters aus seiner Entleerungsstellung selbsttätig und ohne das Vorsehen eines gesonderten Antriebs bewirkt wird.It is an object of the invention to improve a floor cleaning machine so that the pivoting back of the dirt container from its emptying position is effected automatically and without the provision of a separate drive.
Zur Lösung dieser Aufgabe wird eine Bodenreinigungsmaschine der eingangs erwähnten Art erfindungsgemäß derart ausgestaltet, dass die Halteverbindung durch die Verbindung des Parallelarms mit dem Schmutzbehälter und dem maschinenfesten Punkt gebildet wird, dass der Schmutzbehälter beim Absenken des Aushebearms bei gelöster Halteverbindung gegen Verschwenkung bezüglich dem Aushebearm abgestützt wird, um die Halteverbindung wieder herzustellen, und dass die Abstützung des Schmutzbehälters nach Wiederherstellung der Halteverbindung selbsttätig unwirksam gemacht wird.To solve this problem, a floor cleaning machine of the type mentioned is inventively designed such that the holding connection is formed by the connection of the parallel arm with the dirt container and the machine-fixed point that the dirt container is supported when lowering the Aushebearms with dissolved holding connection against pivoting with respect to the Aushebearm in order to restore the holding connection, and that the support of the dirt container is automatically rendered inoperative after restoration of the holding connection.
Bei der erfindungsgemäßen Bodenreinigungsmaschine wird also der in der Entleerungsstellung befindliche Schmutzbehälter beim Absenken des Aushebearms an diesem abgestützt und so in der Entleerungsstellung gehalten. Dies hat zur Folge, dass der Anlenkpunkt des Parallelarms am Schmutzbehälter entlang einer Bahn geführt wird, durch die das innere Ende des Parallelarms in Richtung auf den maschinenfesten Punkt verlagert wird, und zwar bis in eine Stellung, in der die Halteverbindung wiederhergestellt wird. Sobald dies erfolgt ist, befindet sich der Schmutzbehälter in einer Ausrichtung entsprechend der Betriebsstellung und wird bei Fortsetzung der Absenkbewegung des Aushebearms durch das nunmehr wieder wirksame Parallelogrammgestänge in dieser gehalten. Um diese Schwenkbewegung zu ermöglichen, wird die Abstützung des Schmutzbehälters selbsttätig unwirksam gemacht, so dass das Parallelogrammgestänge bzw. die Parallelogrammgestänge den Schmutzbehälter wieder in die Betriebsstellung zurückverlagern können, in der dessen Öffnungsrand dichtend am Öffnungsrand der Schmutzdurchtrittsöffnung anliegt.In the floor cleaning machine according to the invention thus located in the emptying position dirt container is supported when lowering the Aushebearms at this and so kept in the emptying position. This has the consequence that the articulation point of the parallel arm is guided on the dirt container along a path through which the inner end of the parallel arm is displaced towards the machine-fixed point, to a position in which the holding connection is restored. As soon as this is done, the dirt container is in an orientation corresponding to the operating position and is held by the now again effective parallelogram in this continuation of the lowering of the Aushebearms. In order to enable this pivoting movement, the support of the dirt container is automatically rendered ineffective, so that the Parallelogrammgestänge or Parallelogrammgestänge the dirt container can shift back into the operating position in which the opening edge sealingly abuts the opening edge of the dirt passage opening.
Eine besonders vorteilhafte Lösung zur Bewirkung der Abstützung des Schmutzbehälters besteht darin, eine sich an eine Anschlagfläche anlegende Feder vorzusehen, deren Abstützwirkung durch Verformung infolge der zunehmenden Kraftwirkung des sich absenkenden Parallelogrammgestänges unwirksam wird. Diese Feder, die beispielsweise eine am Schmutzbehälter befestigte Blattfeder sein kann, die mit einer am Aushebearm vorgesehenen Anschlagfläche zusammenwirkt, hält den Schmutzbehälter solange in der Entleerungsstellung, bis die Halteverbindung wiederhergestellt ist, d.h. die Feder muss nur eine solche Stützwirkung ausüben, dass die Widerstände überwunden werden, die einer Rückführung des Parallelarms und der Wiederherstellung der Halteverbindung entgegenwirken. Sobald die Halteverbindung hergestellt ist und das dadurch wirksame Parallelogrammgestänge bei der Absenkung des Aushebearms eine entsprechende Kraft zur Verschwenkung des Schmutzbehälters ausübt, wird die Feder verformt, und sie verhindert die Rückführung des Schmutzbehälters in die Betriebsstellung nicht.A particularly advantageous solution for effecting the support of the dirt container is to provide an abutting on a stop surface spring whose support effect is ineffective due to deformation due to the increasing force of the lowering parallelogram linkage. This spring, which may be, for example, a leaf spring attached to the hopper, which cooperates with a stop surface provided on the Aushebearm holds the dirt container while in the emptying position until the holding connection is restored, ie the spring must only exert such a support effect that overcome the resistances be a return of the parallel arm and the restoration of the holding connection counteract. Once the holding connection is made and thereby effective parallelogram in the lowering of the Aushebearms exerts a corresponding force for pivoting the dirt container, the spring is deformed, and it does not prevent the return of the dirt container in the operating position.
Es ist auch möglich, zur Abstützung des Schmutzbehälters beispielsweise einen starren Anschlag vorzusehen, der in abstützenden Eingriff mit einer ersten Führfläche kommt und sich im Verlauf der Absenkbewegung des Aushebearms relativ entlang dieser Führfläche verlagert, so dass auf diese Weise der Parallelarm entsprechend verlagert und die Halteverbindung wiederhergestellt wird. Sobald dies erreicht ist, kommt der Anschlag von der ersten Führfläche frei, und er behindert die Rückschwenkung des Schmutzbehälters durch das Parallelogrammgestänge in die Betriebsstellung nicht mehr.It is also possible to provide, for example, a rigid stop for supporting the dirt container, which comes into supporting engagement with a first guide surface and relatively displaced along this guide surface in the course of the lowering movement of the Aushebearms, so that displaced in this way the parallel arm and the holding connection is restored. Once this is achieved, the stopper comes free from the first guide surface, and it no longer impedes the return pivoting of the dirt container through the parallelogram linkage into the operating position.
Vorzugsweise ist bei einem solchen Aufbau die erste Führfläche am Schmutzbehälter und der starre Anschlag an einem maschinenfesten Punkt vorgesehen. Ferner kann an die erste Führfläche eine zweite Führfläche anschließen, die die Verschwenkung des Schmutzbehälters beim Freikommen des starren Anschlags von der ersten Führfläche begrenzt, so dass es nicht zu einem Überschwingen des Schmutzbehälters kommt.Preferably, in such a structure, the first guide surface is provided on the dirt container and the rigid stop at a machine-fixed point. Furthermore, can connect to the first guide surface, a second guide surface, which limits the pivoting of the dirt container when the free-coming of the rigid stop of the first guide surface, so that there is no overshoot of the dirt container.
Das Lösen der Halteverbindung kann dadurch erfolgen, dass das innere Ende des Parallelarms von dem maschinenfesten Punkt gelöst wird. Um dieses innere Ende bei gelöster Halteverbindung in einer definierten Lage zu halten und es insbesondere beim Absenken des Aushebearms in eine Stellung zurückführen zu können, die die Wiederherstellung der Halteverbindung ermöglicht, kann das innere Ende des Parallelarms in einem Führschlitz geführt werden. Vorteilhafterweise ist es jedoch schwenkbar mit dem oberen Ende eines Hilfsarms verbunden, dessen unteres Ende schwenkbar mit der Bodenreinigungsmaschine verbunden ist. Der Hilfsarm wird bei bestehender Halteverbindung unverschwenkbar gehalten, so dass seine Verbindung mit dem Parallelarm den maschinenfesten Punkt für diesen bildet, während der Hilfsarm zum Lösen der Halteverbindung aus dieser unverschwenkbaren Halterung lösbar ist. Die unverschwenkbare Halterung des Hilfsarms kann beispielsweise durch Eingriff einer Rastklinke bewirkt werden, die die Bedienungsperson in eine Freigabestellung bewegen kann, um auf diese Weise die Halteverbindung zu lösen und so das Verschwenken des Schmutzbehälters in die Entleerungsstellung zu bewirken.The release of the holding connection can be effected in that the inner end of the parallel arm is released from the machine-fixed point. In order to keep this inner end in a defined holding connection in a defined position and to be able to return it particularly when lowering the Aushebearms in a position that allows the restoration of the holding connection, the inner end of the parallel arm can be performed in a guide slot. Advantageously, however, it is pivotally connected to the upper end of an auxiliary arm, the lower end pivotally connected to the floor cleaning machine connected is. The auxiliary arm is held unverschwenkbar in existing holding connection, so that its connection with the parallel arm forms the machine-fixed point for this, while the auxiliary arm for releasing the holding connection from this non-pivoting holder is releasable. The non-pivotal mounting of the auxiliary arm can be effected for example by engagement of a latch, which can move the operator to a release position, in this way to release the holding connection, thus causing the pivoting of the dirt container in the emptying position.
Erfolgt durch Absenken des Aushebearms die Verlagerung des inneren Endes des Parallelarms und damit die Verschwenkung des Hilfsarms zurück in Richtung auf dessen unverschwenkbare Halterung, so kann durch Eingriff mit der Rastklinke die Halteverbindung selbsttätig wiederhergestellt werden. Dazu kann die Rastklinke bei bestehender Halteverbindung beispielsweise in formschlüssigem Eingriff mit einer am Hilfsarm vorgesehenen Riegelfläche stehen.Is done by lowering the Aushebearms the displacement of the inner end of the parallel arm and thus the pivoting of the auxiliary arm back toward its unverschwenkbare holder, it can be restored automatically by engagement with the latch, the holding connection. For this purpose, the detent pawl in existing holding connection, for example, in positive engagement with a provided on the auxiliary arm locking surface.

Der nicht dargestellte Schmutzleitkanal endet an einer unteren Eintrittsöffnung eines Luftführungsgehäuses, in dem sich eine nicht dargestellte Filtereinrichtung befindet, oberhalb derer ein herausnehmbarer Deckel vorgesehen ist. Dieser Aufbau, einschließlich eines in der Seitenwand des Luftführungsgehäuses vorgesehenen, nicht dargestellten Gebläses ist in der älteren
Auf dem Chassis 1 befindet sich eine Haube 7, die beispielsweise gemäß der in der parallelen deutschen Patentanmeldung "Bodenreinigungsmaschine" (
Die dargestellte Bodenreinigungsmaschine unterscheidet sich von derjenigen aus der parallelen älteren deutschen Patentanmeldung "Bodenreinigungsmaschine" (
Die dargestellte Bodenreinigungsmaschine weist einen wannenförmigen Schmutzbehälter 10 auf, wie er auch bei derartigen Bodenreinigungsmaschinen schon üblich ist, der an einer Seit von einem Parallelogrammgestänge gehaltert ist, das am äußeren seitlichen Enden des Schmutzbehälters angreift. In den Figuren ist dieses in Fahrtrichtung an der linken Seite vorgesehen. An der anderen Seite des Schmutzbählters 10 greift nur ein Aushebearm an, wie er nachstehend als Teil des Parellelogrammgestänges beschrieben wird.The floor cleaning machine shown has a trough-shaped
Das Parallelogrammgestänge enthält einen Aushebearm 12, der schwenkbar am oberen Ende einer auf dem Chassis 1 befestigten Stützsäule 11 angebracht ist. Diese Stützsäule ist in verschiedenen Figuren nur teilweise gezeigt, um die Funktionsweise des Parallelogrammgestänges zu verdeutlichen. In diesen Fällen ist in den Figuren das obere Ende der Stützsäule 11' des in den Figuren in Fahrtrichtung an der rechten Seite vorgesehenen Aushebearms zu erkennen.The parallelogram linkage includes a lifting
Das äußere Ende des Aushebearms 12 ist bei 14 schwenkbar mit der Seitenwand des Schmutzbehälters 10 verbunden. In diesem Verbindungsbereich ist an der Seitenwand des Schmutzbehälters eine Platte 31 befestigt, die einen hinsichtlich seiner Funktion noch zu beschreibenden, aus elastisch verformbaren Kunststoff oder Kautschuk bestehenden Anschlag 32 sowie eine ebenfalls noch zu beschreibende Blattfeder 33 trägt.The outer end of
Am Aushebearm 12 greift bei 26 schwenkbar das äußere Ende des Kolbens eines hydraulischen Arbeitszylinders 25 an, der schwenkbar auf dem Chassis 1 befestigt ist und dem in nicht dargestellter Weise von einer vom Verbrennungsmotor angetriebenen Hydraulikpumpe Hydraulikflüssigkeit zugeführt werden kann, um den Aushebearm 12 aus der Betriebsstellung des Schmutzbehälters 10 gemäß
Als weiteres Element des Parallelogrammgestänges ist unterhalb der Anlenkung 14 des äußeren Endes des Aushebearms 12 an der Seitenwand des Schmutzbehälters 10 ein Parallelarm 15 mit seinem äußeren Ende bei 17 angelenkt. Das innere Ende des Parallelarms 15 ist bei 16 schwenkbar mit dem oberen Ende eines Hilfsarms 18 verbunden. Der Hilfsarm 18 ist bei 19 an einem gehäusefesten Punkt schwenkbar befestigt, und er weist einen Führstift auf, der in einen Führschlitz in einem gehäusefesten Führblech 20 eingreift, so dass der Führstift bei der noch zu beschreibenden Verschwenkung des Hilfsarms 18 in dem Führschlitz geführt wird und den Hilfsarm 18 abstützt.As a further element of the parallelogram linkage, a
Der Hilfsarm 18 trägt an seinem oberen Ende einen Vorsprung 21, der in der Betriebsstellung des Schmutzbehälters (

Zum Entleeren des Schmutzbehälters 10 verschwenkt die Bedienungsperson den Betätigungshebel 27 und zieht dadurch mittels des Bowdenzuges 28 die Klinke 30 herunter, so dass der Vorsprung 21 des Hilfsarms 18 freikommt, der Parallelarm 15 den Schmutzbehälter 10 also nicht mehr abstützt. Infolge der Lage des Schwerpunktes des Schmutzbehälters 10 schwenkt dieser daher um den Anlenkpunkt 14 in die Entleerungsstellung gemäß
Beim Lösen des Hilfsarms 18 kann es vorkommen, dass Schmutzbehälter 10 infolge seiner trägen Masse, insbesondere dann, wenn er stark befüllt ist, über die dargestellte Enleerungsstellung hinaus und unter entsprechender elastischer Verformung der nachstehend beschriebenen Blattfeder 33 (in den Figuren) im Gegenuhrzeigersinn überschwingt. Dies wird durch den am Schmutzbehälter 10 angebrachten Anschlag 32 verhindert, der die Verschwenkbewegung des Schmutzbehälters 10 durch Anlage am Aushebearm 12 begrenzt.When loosening the
Die Bodenreinigungsmaschine wird nunmehr nach weiterem Anheben des Schmutzbehälters verfahren, so dass der Schmutzbehälter 10 aus dem Bereich des Containers C kommt, und dann wird der Aushebearm 12 abgesenkt. Wie ein Vergleich der diesen Absenkvorgang zeigenden
Bei der Absenkung des wirksamen Parallelogrammgestänges führt der Anlenkpunkt 17 des äußeren Endes des Parallelarms 15 eine bogenförmige Bewegung um den Anlenkpunkt 14 des äußeren Endes des Aushebearms 12 durch, und zwar in den Figuren im Gegenuhrzeigersinn, wodurch während der Absenkbewegung die Ausrichtung des Schmutzbehälters 10 im Raum beibehalten wird. Dies wurde vor dem Wiederherstellen des Eingriffs zwischen Klinke 30 und Vorsprung 21 durch die Wirkung der Blattfeder 33, die sich am Vorsprung 34 des Auslegearms 15 abstützt, verhindert. Auf diese Weise erfolgte die Wiederherstellung des Verriegelungseingriffes zwischen Klinke 30 und Vorsprung 21 und damit die Wiederherstellung der Halteverbindung durch Verbindung des Parallelarms 15 mit dem maschinenfesten Punkt. Sobald diese Halteverbindung hergestellt und dadurch das Parallelogrammgestänge wirksam gemacht ist, verlagert sich beim weiteren Absenken der Anlenkpunkt 17 des äußeren Endes des Parallelarms 15 also in den
