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-PS 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-PS 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 impellers.

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 attach the LedigLich drive wheels to the axles. The axes themselves are extremely quickly mounted over 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. Because the drive wheels are simply plugged onto the axle, it is also possible to make them smooth on the outside. This also meets fashion requirements, according to which the drive impellers 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 design of the bearing hole 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 exemplary embodiment of the invention is explained in more detail below with reference to the drawings.

Es zeigen:

  • Figur 1 eine Gesamtansicht eines Kehrgerätes,
  • Figur 2 ein Schnitt gemäß der Linie II-II nach Figur 1, wobei Links das Antriebslaufrad in Ansicht und rechts im Schnitt gezeichnet ist,
  • Figur 3 eine Detailvergrößerung gemäß dem Ausschnitt III 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 II-II according to FIG. 1, the drive impeller being drawn in view on the left and in section on the right,
  • Figure 3 shows an enlarged detail according to section III of Figure 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 impellers 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 elongated hole-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 and engage in the thrust washers 11 of the drive impellers 5. This makes it possible for the drive impellers 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 impellers 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.
