Description

Die Erfindung betrifft ein Teppich-Pftegegerät gemäß Oberbegriff des Anspruchs 1.The invention relates to a carpet care device according to the preamble of claim 1.

Bei einer bekannten derartigen Ausgestaltung ist eine Tragachse in einer aus mehreren zusammensteckbaren Teilen gebildeten hohlen Welle angeordnet, wobei die Drehmoment-Übertragung auf die beiderseits der Antriebsstelle vorgesehenen Bürsten über die hohlen Welle erfolgt. Als nachteilig an dieser Ausgestaltung erweisen sich die hohen Herstellungskosten der hohlen Welle sowie die aufwendige Montage.In a known configuration of this type, a support shaft is arranged in a hollow shaft formed from a plurality of parts which can be plugged together, the torque being transmitted to the brushes provided on both sides of the drive point via the hollow shaft. The high manufacturing costs of the hollow shaft and the complex assembly prove to be disadvantageous in this configuration.

Dem Gegenstand der Erfindung liegt die Aufgabe zugrunde, ein Teppich-Pflegegerät der vorausgesetzten Gattung so auszugestalten, daß neben einer günstigen Drehmomentübertragung auf die Bürstenwalzen die Herstellungskosten senkbar und die Montage vereinfacht sind.The object of the invention is based on the object of designing a carpet care device of the type required in such a way that, in addition to favorable torque transmission to the brush rollers, the production costs can be reduced and the assembly simplified.

Gelöst wird diese Aufgabe durch das Kennzeichen des Anspruchs 1.This problem is solved by the characterizing part of claim 1.

Zufolge derartiger Ausgestaltung ist ein gattungsgemäßes Teppich-Pflegegerät angegeben, welches sich einerseits durch eine einfache Montage auszeichnet und andererseits den Vorteil geringerer Herstellungskosten bringt. Die Drehmomentübertragung der Bürstenwalzen erfolgt nun nicht mehr über die Welle selbst. Diese hat nur die Aufgabe einer Stützfunktion. Die Welle kann durchgehend glatt ausgebildet sein und stellt dadurch ein sehr einfaches, kostengünstig zu fertigendes Automatenteil dar. Die Drehmomentübertragung auf die Bürstenwalzen geschieht über die Gegenklauen der Nabe des Antriebszahnrades, welche Gegenklauen formschlüssig in die Kupplungsklauen der Kupplungsbüchsen eingreifen, die endseitig Kopfstücke tragen. Die stehen wiederum in Steck-Rastverbindung mit den Bürstenwalzen. Eine beiderseits der Antriebsstelle brückenartige Abstützung erhält die Welle durch die von den Kupplungsbüchsen der Kopfstücke durchsetzten gehäuseseitigen Kugellagern. Das Montieren der Bürstenwalzen und der mit diesen zusammenwirkenden Bauteile kann im Wege der Steckmontage ausgeführt werden. Vorerst sind das Antriebsrad sowie die beiderseits davon befindlichen Kugellager zu positionieren. Anschließend sind die Kupplungsbüchsen durch die Kugellager zu stekken, deren Kupplungsklauen in die Gegenklauen der Nabe des Antriebszahnrades eingreifen. Der nächste Arbeitsschritt besteht darin, die Bürstenwalzen auf die Wellenenden aufzuschieben unter Herstellung der Steck-Verrastung mit den Kopfstücken. Ein Auswechseln der Bürstenwalzen nach einem etwaigen Verschleiß ist daher auch sehr vereinfacht.As a result of such a configuration, a generic carpet care device is specified, which is characterized on the one hand by simple assembly and on the other hand has the advantage of lower production costs. The torque transfer of the brush rollers is no longer carried out via the shaft itself. This only has the function of a support function. The shaft can be smooth throughout and thus represents a very simple, inexpensive machine part to be produced. The torque is transferred to the brush rollers via the counterclaws of the hub of the drive gear, which counterclaws form-fit into the clutch claws of the coupling sleeves, which have end pieces at the ends. These are in turn plug-in with the brush rollers. The shaft receives a bridge-like support on both sides of the drive point through the ball bearings on the housing side, which are penetrated by the coupling sleeves of the head pieces. The brush rollers and the components interacting with them can be assembled by means of plug-in assembly. For the time being, the drive wheel and the ball bearings on both sides of it are to be positioned. Then the coupling bushes are to be inserted through the ball bearings, the coupling claws of which engage in the counterclaws of the hub of the drive gear. The next step is to push the brush rollers onto the shaft ends, making the push-fit with the head pieces. Replacing the brush rollers after any wear is therefore also very simplified.

Eine vorteilhafte Weiterbildung besteht darin, daß die Kupplungsbüchsen federnde Finger mit Auflaufschrägen besitzen, welche vor den Kugellager-Innenring schnappen. Das bedeutet, daß nach Durchstecken der Kupplungsbüchsen durch die Kugellager die Kupplungsbüchsen in Achsrichtung fixiert sind. Wird dann die Welle eingebracht, können die federnden Finger nicht aus ihrer Sicherungsstellung treten.An advantageous development is that the coupling sleeves have resilient fingers with bevels that snap in front of the inner ring of the ball bearing. This means that after the coupling bushes have been pushed through the ball bearings, the coupling bushes are fixed in the axial direction. If the shaft is then inserted, the resilient fingers cannot move out of their secured position.

Ein weiteres vorteilhaftes Merkmal besteht darin, daß die Kugellager von topfförmigen Hülsen des Gehäuses umfaßt sind und die Welle sich über die Hülsen hinaus bis in Naben der Bürstenwalzen erstreckt, deren Stirnendöffnungen von eingeklipsten Deckeln verschlossen sind, die eine topfförmige Eintrittsbohrung für das Ende der Welle besitzen. Die die Kugellager aufnehmenden Gehäuseabschnitte können demgemäß schalenartig ausgebildet sein. Das Einsetzen der Kugellager ist dadurch vereinfacht. Die auf die Gehäuseabschnitte gesteckten topfförmigen Hülsen sichern die Lage der Kugellager, welche gleichzeitig die Welle abstützen. Die Enden derselben greifen in die Naben der Bürstenwalzen ein sowie in die topfförmigen Eintrittsbohrungen der in den Stirnendöffnungen eingeklipsten Deckel. Die beiden Deckel dienen zur axialen Lagesicherung der Welle. Nach Entfernen eines Deckels ist es möglich, die Welle herauszuziehen.Another advantageous feature is that the ball bearings are surrounded by cup-shaped sleeves of the housing and the shaft extends beyond the sleeves into the hubs of the brush rollers, the end openings of which are closed by clipped-on covers which have a cup-shaped entry bore for the end of the shaft . The housing sections accommodating the ball bearings can accordingly be of shell-like design. The insertion of the ball bearings is simplified. The cup-shaped sleeves placed on the housing sections secure the position of the ball bearings, which simultaneously support the shaft. The ends of these engage in the hubs of the brush rollers and in the cup-shaped inlet bores in the End openings clipped in lid. The two covers are used to axially secure the shaft. After removing a cover, it is possible to pull out the shaft.

Damit die Bürstenwalzen nicht ungewollt aus ihrer vorschriftsmäßigen Steck-Rastverbindung treten, sind den Kopfstücken Auswerferfedern für die Bürstenwalzen zugeordnet.Ejector springs for the brush rollers are assigned to the head pieces so that the brush rollers do not accidentally come out of their plug-in snap-in connection.

Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Fig. 1 bis 6 erläutert. Es zeigt:

  • Fig. 1 in etwa natürlichem Maßstab strichpunktiert ein Gehäuse eines Teppich-Pflegegeräts, welches beiderseits der Antriebsstelle fliegend ausladende, auf einer Welle angeordnete Bürstenwalzen aufweist, wobei bei einer Bürstenwalze zwecks vereinfachter Darstellung die Bürsten nicht veranschaulicht sind,

An exemplary embodiment of the invention is explained below with reference to FIGS. 1 to 6. It shows:
  • 1 on a natural scale, dash-dotted lines, a housing of a carpet care device, which has on both sides of the drive point overhanging brush rollers arranged on a shaft, the brushes not being illustrated in the case of a brush roller for the purpose of simplified illustration,
  • 2 shows a longitudinal central section through a brush roller arranged on the shaft,
  • 3 shows the section along the line 111-II1 in FIG. 2,
  • 4 shows the section along the line IV-IV in FIG. 2,
  • Fig. 5 shows the section along the line VV in Fig. 2 and
  • Fig. 6 partly in view, partly in section, a pre-assembly position, before inserting a head piece provided with a coupling sleeve.

Das dargestellte Teppich-Pflegegerät besitzt ein strichpunktiert dargestelltes Gehäuse 1. Dieses ist etwa T-förmig gestaltet. In dem T-Steg 2 befindet sich ein nicht veranschaulichter Getriebemotor, während der T-Balken 3 Bürstenwalzen 4, 5 aufnimmt.The carpet care device shown has a dash-dot housing 1. This is approximately T-shaped. In the T-bar 2 there is a gear motor, not shown, while the T-bar 3 receives brush rollers 4, 5.

In dem T-Steg 2 des Gehäuses 1 ist eine Getriebebrücke 6 befestigt. Diese setzt sich beiderseits einer mittleren Antriebsstelle in zwei Halbschalen 7, 8 fort. Zwischen beiden Halbschalen 7, 8 erstreckt sich ein Antriebszahnrad 9, welches undrehbar und unverschieblich auf einer Nabe 10 sitzt. Letztere überragt beidseitig das die Antriebsstelle bildende Antriebszahnrad 9 und formt endseitig Gegenklauen 11. Diese stehen in formschlüssigem Eingriff mit Kupplungsklauen 12 koaxial zur Nabe 10 angeordneter Kupplungsbüchsen 13, die innenringe 14 von Kugellagern 15 durchsetzen. Die Kugellager 15 sind eingelassen in die Halbschalen 7, 8 der Getriebebrücke und dort von Schultern 16, 17 gesichert. Über jede Halbschale 7, 8 ist eine topfförmige Hülse 18 geschoben, deren Topfrand 18' sich an einer Stufe 19' der Getriebebrücke 6 abstützt.A gear bridge 6 is fastened in the T-web 2 of the housing 1. This continues on both sides of a middle drive point in two half-shells 7, 8. A drive gear 9 extends between the two half-shells 7, 8 and sits non-rotatably and immovably on a hub 10. The latter protrudes on both sides of the drive gear 9 forming the drive point and forms counter-claws 11 at the end. These are in positive engagement with clutch claws 12, which are arranged coaxially to the hub 10, clutch bushings 13 which pass through the inner rings 14 of ball bearings 15. The ball bearings 15 are embedded in the half-shells 7, 8 of the gear bridge and secured there by shoulders 16, 17. A cup-shaped sleeve 18 is pushed over each half-shell 7, 8, the cup edge 18 'of which is supported on a step 19' of the gear bridge 6.

Jede Kupplungsbüchse 13 ist mit sich in Achsrichtung erstreckenden federnden Fingern 20 versehen, welche an ihrem der Antriebsstelle abgewendeten Enden Auflaufschrägen 21 ausbilden. Die Fingerenden 22 erstrecken sich vor den Innenringen 14 der Kugellager 15. Eine axiale Unverschieblichkeit erhalten die Kupplungsbüchsen 13 durch eine den Fingerenden 22 gegenüberliegende Stützschulter 23.Each coupling sleeve 13 is provided with resilient fingers 20 which extend in the axial direction and which form bevels 21 at their ends facing away from the drive point. The finger ends 22 extend in front of the inner rings 14 of the ball bearings 15. The coupling bushes 13 are axially immovable by a support shoulder 23 opposite the finger ends 22.

Jenseits der Stützschulter 23 setzt sich jede Kupplungsbüchse 13 in ein Kopfstück 24 fort. Von der Stirnseite des Kopfstückes 24 sind beim Ausführungsbeispiel vier Bajonettschlitze 25 eingearbeitet derart, daß die Einführenden 25' trichterförmig erbreitert sind. Sodann enthält das Kopfstück eine mittlere Bohrung 26 zur Aufnahme einer Druckfeder 27. In die Bajonettschlitze 25 greifen kreuzend zueinander angeordnete Stege 28 ein, die den Bürstenwalzen-Mantel 29 mit der Nabe 30 der Bürstenwalze verbinden. Die Stege 28 erstrecken sich in den Abschnitten 25" der Bajonettschlitze 25. Zufolge der Druckfeder 27, die sich einerseits am Kopfstück 24 und andererseits an der Nabe 30 der Bürstenwalze abstützt, verbleiben die Stege in den Abschnitten 25".Beyond the support shoulder 23, each coupling sleeve 13 continues into a head piece 24. In the exemplary embodiment, four bayonet slots 25 are incorporated from the end face of the head piece 24 in such a way that the insertion ends 25 'are widened in a funnel shape. Then the head piece contains a central bore 26 for receiving a compression spring 27. In the bayonet slots 25, crosswise arranged webs 28 engage, which connect the brush roller casing 29 to the hub 30 of the brush roller. The webs 28 extend in the sections 25 "of the bayonet slots 25. As a result of the compression spring 27, which is supported on the one hand on the head piece 24 and on the other hand on the hub 30 of the brush roller, the webs remain in the sections 25".

Ferner sind die Bürstenwalzen 4, 5 mit Speichenwänden 31 ausgestattet, die die Nabe 30 mit dem Mantel 29 verbinden.Furthermore, the brush rollers 4, 5 are equipped with spoke walls 31 which connect the hub 30 to the casing 29.

Die Stirnendöffnungen der Bürstenwalzen 4, 5 sind von eingeklipsten Deckeln 32 verschlossen. Im einzelnen besitzt jeder Deckel 32 eine Topfform. Der auswärtsgerichtete Topfrand 33 stützt sich an dem Stirnende der Bürstenwalze 4 bzw. 5 ab. Vom Topfboden gehen bürstenwalzeneinwärts gerichtete Stege 34 aus, deren auswärts weisende Rastnasen 35 klipsend in formangepaßte Öffnungen 36 der Bürstenwalze 4 bzw. 5 eingreifen.The end openings of the brush rollers 4, 5 are closed by clipped-on covers 32. In particular, each lid 32 has a pot shape. The outwardly directed pot edge 33 is supported on the front end of the brush roller 4 or 5. From the bottom of the pot, there are webs 34 directed inward of the brush rollers, the outward-facing latching lugs 35 of which engage in clips 36 of the brush roller 4 and 5 that conform to the shape.

Jeder Topfboden der Deckel 32 formt bürsteneinwärtsgerichtete Büchsen 37. In die Eintrittsbohrungen 38 der Büchsen 37 der Deckel ragen die freien Enden 39 einer Welle 40, welche die Nabe 10 des Antriebszahnrades 9, die Kupplungsbüchsen 13, die Kopfstücke 24 sowie die Naben 30 der Bürstenwalzen 4, 5 durchsetzt. Sämtliche vorstehend genannten Bauteile sitzen drehbar auf der Welle 40, so daß das von einer nicht dargestellten Schnecke in Umdrehung versetzte Antriebszahnrad 9 über die Klauenkupplungs-Verbindungen 11, 12 die Kupplungsbüchsen 13 mit den daran befestigten Kopfstücken 24 antreibt, welche ihrerseits zufolge der Bajonettschlitze 25 die Bürstenwalzen 4, 5 mitnehmen.Each pot bottom of the cover 32 forms brush-oriented bushes 37. The free ends 39 of a shaft 40, which the hub 10 of the drive gear 9, the coupling bushes 13, the head pieces 24 and the hubs 30 of the brush rollers 4 protrude into the inlet bores 38 of the bushes 37 of the cover , 5 interspersed. All of the above-mentioned components are rotatably seated on the shaft 40, so that the drive gear 9, which is rotated by a worm (not shown), drives the coupling sleeves 13 with the head pieces 24 attached to them via the claw coupling connections 11, 12, which in turn, according to the bayonet slots 25, the Take brush rollers 4, 5 with you.

Die Montage der mit den Bürstenwalzen zusammenwirkenden Bauteile geschieht derart, daß vorerst in die Halbschalen 7, 8 der Getriebebrücke 6 die -Kugellager 15 eingesetzt werden. Dann erfolgt das Aufschieben der Hülsen 18 auf die Halbschalen. Anschließend ist das Antriebszahnrad 9 in der Getriebebrücke 6 zu positionieren, woraufhin die Kupplungsbüchsen 13 unter Durchsetzen der Kugellager 15 angebracht werden. Deren Kupplungsklauen 12 treten dabei in Eingriff mit den Gegenklauen 11 der Nabe 10 des Antriebszahnrades 9. In der Endphase der Einsteckverlagerung der Kupplungsbüchsen 13 hintergreifen die zuvor federnd ausweichenden Finger 20 den Innenring 14 der Kugellager 15. Danach wird die Welle 40 eingeschoben, die das Einwärtsfedern der Finger 20 ausschließt. Der letzte Montageschritt besteht darin, die Bürstenwalzen 4, 5 in Steck-Rastverbindung mit den Kopfstücken 24 zu bringen. Zu diesem Zweck werden die Stege 28 In die BaJonettschlitze 25 eingeführt, wobei die als Auswerferfeder dienende Druckfeder 27 aufgeladen wird. Nach einer Verdrehung der Bürstenwalze gelangen die Stege 28 in die ihnen zugeordneten Abschnitte 25" der Bajonettschlitze 25.The assembly of the components interacting with the brush rollers takes place in such a way that the ball bearings 15 are initially inserted into the half-shells 7, 8 of the gear bridge 6. Then the sleeves 18 are pushed onto the half-shells. Subsequently, the drive gear 9 is to be positioned in the gear bridge 6, whereupon the coupling sleeves 13 are attached while the ball bearings 15 pass through. Their clutch claws 12 engage with the counter claws 11 of the hub 10 of the drive gear 9. In the final phase of the insertion displacement of the clutch sleeves 13, the previously resilient fingers 20 engage behind the inner ring 14 of the ball bearings 15. Then the shaft 40 is inserted, which springs inwards the finger 20 excludes. The last assembly step consists in bringing the brush rollers 4, 5 into plug-in locking connection with the head pieces 24. For this purpose, the webs 28 are inserted into the bayonet slots 25, the compression spring 27 serving as an ejector spring being charged. After the brush roller has been rotated, the webs 28 enter the sections 25 ″ of the bayonet slots 25 assigned to them.

Sollten die Deckel 32 noch nicht den Bürstenwalzen 4, 5 zugeordnet sein, so kann dieses anschließend durch Aufklipsen geschehen, so daß die Welle 40 mit ihren Enden 39 in den Eintrittsbohrungen 38 der Deckel 32 einliegt unter Erzielung einer axialen Lagesicherung.If the cover 32 is not yet assigned to the brush rollers 4, 5, this can then be done by clipping on, so that the ends of the shaft 40 in the inlet bores 38 of the cover 32 lie to achieve an axial position securing.

Ein Auswechseln der Bürstenwalzen 4, 5 geschieht durch Druck auf diese in Richtung der Antriebsstelle und anschließender Drehung, wobei die Stege 28 der Bürstenwalzen 4, 5 die Bajonettschlitze 25 verlassen können. Unterstützt wird das Abziehen der Bürstenwalzen von der Welle durch die Auswerferfedern 27.The brush rollers 4, 5 are replaced by pressure on them in the direction of the drive point and subsequent rotation, the webs 28 of the brush rollers 4, 5 being able to leave the bayonet slots 25. The removal of the brush rollers from the shaft is supported by the ejector springs 27.

Alle in der Beschreibung erwähnten und in der Zeichnung dargestellten neuen Merkmale sind erfindungswesentlich, auch soweit sie in den Ansprüchen nicht ausdrücklich beansprucht sind.All the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
