Abstract

Mechanical sweeper with slotlike bearing bores with introduction slits in partition walls and outwardly open wheel recesses in the housing wherein the drive/running wheels are closed externally with a smooth surface and are retained by check plates and retaining pockets on the partition walls.

Description

Die Erfindung bezieht sich auf ein Kehrgerät gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a sweeper according to the preamble of claim 1.

Durch die DE-A-22 59 964 ist ein derartiges Kehrgerät bekannt. Die Lagerung der Achsen für die Antriebslaufräder ist aber sehr aufwendig und montagefeindlich.Such a sweeper is known from DE-A-22 59 964. The storage of the axles for the drive wheels is very complex and easy to assemble.

Aufgabe der Erfindung ist es, ein Kehrgerät zu schaffen, bei dem die Achsen derart gelagert sind, daß eine einfache Montage möglich ist und zudem das Gehäuse im Bereich der Antriebslaufräder frei gespart sein kann.The object of the invention is to provide a sweeper in which the axles are mounted in such a way that simple assembly is possible and, moreover, the housing can be freely saved in the area of the drive wheels.

Diese Aufgabe wird -mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Durch diese Lagerung der Achsen ist es möglich, die Antriebslaufräder lediglich auf die Achsen aufzustecken. Die Achsen selbst sind äußerst schnell über die Einführschlitze montiert.This object is achieved with the characterizing features of claim 1. This mounting of the axles makes it possible to simply attach the drive wheels to the axles. The axes themselves are installed extremely quickly via the insertion slots.

Weitere Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen. Durch die Möglichkeit des bloßen Aufsteckens der Antriebslaufräder auf die Achse ist es auch möglich, diese außenseitig glatt zu gestalten. Dies kommt insbesondere auch modischen Anforderungen entgegen, nach denen die Antriebslaufräder frei sichtbar sein sollen.Further embodiments of the invention can be found in the subclaims. By simply plugging the drive wheels onto the axle, it is also possible to make them smooth on the outside. This also meets fashion requirements, according to which the drive wheels should be freely visible.

Dessen ungeachtet hat dies auch Vorteile für die Reinigung des Gerätes. Die Ausführung der Lagerbohrung als L-förmiger Einführschlitz bringt zu der einfachen Montage noch eine weitere Sicherheit in der Lagerung. Selbst bei Extrembelastung, hervorgerufen durch nicht ganz sachgemäße Handhabung, kann die Achse nicht herausspringen.Nevertheless, this also has advantages for cleaning the device. The execution of the bearing bore as an L-shaped insertion slot brings additional security to the storage for easy installation. Even under extreme loads, caused by improper handling, the axis cannot jump out.

Ein Ausführungsbeispiel der Erfindung wird im folgenden an Hand der Zeichnungen näher erläutert.An embodiment of the invention is explained below with reference to the drawings.

Es zeigen :

  • Figur 1 eine Gesamtansicht eines Kehrgerätes,
  • Figur 2 ein Schnitt gemäß der Linie 11-11 nach Figur 1, wobei links das Antriebslaufrad in Ansicht und rechts im Schnitt gezeichnet ist,
  • Figur 3 eine Detailvergrößerung gemäß dem Ausschnitt 111 nach Figur 2 und
  • Figur 4 ein Schnitt gemäß der Linie IV-IV nach Figur 2.
Show it :
  • FIG. 1 shows an overall view of a sweeper,
  • FIG. 2 shows a section along the line 11-11 according to FIG. 1, the drive impeller being drawn in view on the left and in section on the right,
  • FIG. 3 shows an enlarged detail according to section 111 according to FIGS. 2 and
  • Figure 4 is a section along the line IV-IV of Figure 2.

Der Kehrer besteht äußerlich im Wesentlichen aus einem Gehäuse 1, einem Stielbügel 2 mit einem Stiel 3, einer Walzenbürste 4, Antriebslaufräder 5 und diese tragende Achsen 6.On the outside, the sweeper essentially consists of a housing 1, a handle bracket 2 with a handle 3, a roller brush 4, drive wheels 5 and axles 6 supporting them.

Die Achsen 6 werden von langlochartigen Lagerbohrungen 7, die in Einführschlitze 8 übergehen, aufgenommen. Ein Herausfallen der Achsen 6 wird durch den Gegendruck der Walzenbürste 4 beziehungsweise eines nicht näher dargestellten Reibrades verhindert. Die Lagerbohrungen 7 befinden sich in Zwischenwänden 9 des Gehäuses 1.The axes 6 are received by slot-like bearing bores 7, which merge into insertion slots 8. The axes 6 are prevented from falling out by the counterpressure of the roller brush 4 or a friction wheel (not shown in more detail). The bearing bores 7 are located in the partition walls 9 of the housing 1.

An den Zwischenwänden 9 sind Haltetaschen 10 angeformt, in die Anlaufscheiben 11 der Antriebslaufräder 5 eingreifen. Dadurch ist es möglich, daß die Antriebslaufräder ohne zusätzliche Halteeinrichtung auf die Enden 12 der Achsen 6 aufgesetzt sind.Holding pockets 10 are formed on the intermediate walls 9, into which thrust washers 11 of the drive wheels 5 engage. This makes it possible for the drive wheels to be placed on the ends 12 of the axles 6 without an additional holding device.

Das Gehäuse 1 ist im Bereich 13 der Antriebslaufräder 5 frei gespart. Die Antriebslaufräder 5 sind nur einseitig mit einer Lagernabe 14 versehen. Der nach Außen weisende Teil ist glattflächig mit einer Schutzkappe 15 verschlossen. Diese Schutzkappe 15 dient gleichzeitig als Halterung für den Laufradgummi 16.The housing 1 is freely saved in the area 13 of the drive wheels 5. The drive wheels 5 are provided on one side only with a bearing hub 14. The part facing outwards is closed with a smooth protective cap 15. This protective cap 15 also serves as a holder for the impeller rubber 16.

Claims (3)

1. Sweeper which essentially consists of a housing (1), in which axles (6) for drive travel wheels (5) for the drive of a revolving brush (4) are mounted in slotted bearing bores (7, 8) having in each case an insertion slot, at least one dirt- collecting -container and a guide handle (3), characterized in that the drive travel wheels (5) are provided in each case with a check disc (11), and the housing (1) is provided with two intermediate walls and/or retaining pockets (10), behind which grip the check discs (11) for retaining the drive travel wheels.
2. Sweeper according to Claim 1, characterized in that the housing (1) is recessed in the area of the drive travel wheels (5) and the latter are closed towards the outside in smooth-faced manner.
3. Sweeper according to Claim 1 or 2, characterized in that the insertion slot (8) is arranged approximately perpendicularly and merges into the approximately horizontaly disposed bearing bore (7) made like an elongated hole.
