Abstract

The invention relates to a nozzle (1) for a vacuum cleaner (2) to which the suction unit is attached in a decentralised manner at a hinge joint (8), the weight of the suction unit engaging outside the centre of gravity of the appliance. For the even distribution of the weight of the machine, it is proposed to mount one or more springs (11) at the hinge joint. <IMAGE>

Description

Die Erfindung betrifft ein Mundstück für einen Staubsauger an dem die Saugeinheit dezentral an einem Kippgelenk angelenkt ist, wobei die Gewichtskraft der Saugeinhelt außerhalb da Geräteschwerpunkts angreift und insbesondere elektrisch betriebene Bürst- und Poliermaschinen für die Fußbodenbearbeltung mit mehreren Bürst- bzw. Polierscheiben.The invention relates to a mouthpiece for a vacuum cleaner on which the suction unit is articulated decentrally on a tilting joint, the weight of the suction unit acting outside of the center of gravity of the device and in particular electrically operated brushing and polishing machines for floor treatment with several brushing or polishing disks.

Bisher sind in der Technik Federentlastungssysteme unterschiedlicher Art bekannt. So zeigt das DE- Gebrauchsmuster 3618803.4 beispielsweise die Verringerung der Schiebekraft eines Staubsaugermundstücks auf dem Untergrund mit Hilfe einer Feder.
Ein Entlastungssystem, das die Gewichtskraft eines Staubsaugers, der dezentral an ein Mundstück angeschlossen ist, auf alle Bürst- bzw. Pollerschelben verteilt, existiert jedoch bisher nicht.
Infolge dieser fehlenden Einrichtung werden die Scheiben je nach der auf sie wirkenden Gewichtskraft unterschiedlich stark abgenutzt. Das macht den häufigen Austausch der durch die ungleichmäßige Gewichtsverteilung teilweise stark abgenutzten Scheiben notwendig. Diese Ersatzteilbeschaffung ist mit auf die Dauer hohen Kosten für den Verbraucher verbunden.
Die einseitige Gewichtsverteilung macht sich außerdem negativ bemerkbar, indem beim Bearbelten des Fußbodens die Maschine "wegläuft". Diese Erscheinung läßt sich dadurch erklären, daß die Scheibe, die stärker als die anderen belastet wird, so stark auf den Untergrund gepreßt wird, daß sie antreibend wirkt und die Maschine seitlich ausschert. Um effektiv arbeiten zu können, muß der Benutzer der Maschine ständig einen Gegendruck gegen das Ausscheren aufbringen, was unnötige Anstrengungen erfordet.So far, spring relief systems of various types are known in the art. For example, DE utility model 3618803.4 shows the reduction of the pushing force of a vacuum cleaner nozzle on the surface with the aid of a spring.
However, a relief system that distributes the weight of a vacuum cleaner, which is connected decentrally to a mouthpiece, to all brush or bollard heads does not yet exist.
As a result of this missing device, the disks are worn to different extents depending on the weight force acting on them. This necessitates the frequent replacement of the disks, which are sometimes very worn due to the uneven weight distribution. This procurement of spare parts is associated with long-term high costs for the consumer.
The one-sided weight distribution also has a negative impact because the machine "runs away" when the floor is tiled. This phenomenon can be explained by the fact that the disc, which is more heavily loaded than the others, is pressed onto the surface so strongly that it has a driving effect and the machine swings out to the side. In order to operate effectively, the user of the machine must constantly apply back pressure against the shear, which requires unnecessary effort.

Aufgabe der Erfindung ist es deshalb, sicherzustellen, daß die Gewichtskraft der Maschine so gleichmäßig verteilt wird, daß die obengenannten Nachteile nicht mehr auftreten. Gelöst ist diese Aufgabe durch die in Anspruch 1 dargelegte Erfindung. Die Unteransprüche 2 bis 5 sind vorteilhafte Ausgestaltungen der Erfindung.The object of the invention is therefore to ensure that the weight of the machine is distributed so evenly that the above-mentioned disadvantages no longer occur. This object is achieved by the invention set out in claim 1. The sub-claims 2 to 5 are advantageous embodiments of the invention.

Die Vorteile der erfinderischen Lösung liegen insbesondere darin, daß durch die gieichäßige Gewichtsverteilung der Maschine über alle Scheiben keine einseitige Abnutzung einiger Scheiben mehr auftritt. Die Scheiben müssen seltener ausgetauscht werden, und die Ersatzteilkosten werden gespart. Das Gerät schert auch nicht mehr seitlich aus, was für den Benutzer ein wesentlich leichteres und praktischeres Arbeiten bedeutet.
Durch einen Schalter, der das Gerät beim Abstellen automatisch abschaltet, ist gewährleistet, daß es sich selbst im Stand bei voller Gewichtskraftwirkung des Aufsatzgerätes auf eine Stelle des Bohnervorsatzes nicht von selbst von der Stelle bewegt.The advantages of the inventive solution are, in particular, that none due to the uniform weight distribution of the machine over all disks one-sided wear of some discs occurs more. The disks have to be replaced less frequently and the spare parts costs are saved. The device also no longer swings out to the side, which means that working is much easier and more practical for the user.
A switch that automatically switches the device off when it is switched off ensures that it does not move automatically from its own place to a point on the front attachment even when the attachment is fully weight-bearing.

Der Gegenstand der Erfindung ist nachstehend anhand eines zeichnerisch veranschaulichten Ausführungsbeispiels näher erläutert.The subject matter of the invention is explained in more detail below on the basis of an illustrative embodiment.

Figur 1 zeigt die Kräfteverteilung in der Bürst- und Poliermaschine, wobei F₂ (4) den Schwerpunkt des Staubsaugers (2) außerhalb des Bohnervorsatzes (1) und F₁ (3) den Schwerpunkt des Bohnervosatzes (1) darstellt. Aufgrund dieser Kräfte (3 und 4) ist die Auflagekraft der Arbeitsscheiben (6) auf dem Boden unterschiedlich.
Um dies auszugleichen, sind am Kippgelenk (8) Ausgleichsfedern (11) angeordnet. Sie verlagern die außerhalb des Bohnervorsatzes (1) liegende Gewichtskraft F₂ (4) auf die Handlast F₃ (5) und den Schwerpunkt des Bohnervorsatzes (1) F₁ (3).Figure 1 shows the distribution of forces in the brushing and polishing machine, F₂ (4) being the center of gravity of the vacuum cleaner (2) outside the polisher (1) and F₁ (3) being the center of gravity of the polisher (1). Because of these forces (3 and 4), the contact force of the working discs (6) on the ground is different.
In order to compensate for this, compensating springs (11) are arranged on the tilt joint (8). You shift the weight force F₂ (4) lying outside the front attachment (1) to the hand load F₃ (5) and the center of gravity of the front attachment (1) F₁ (3).

Dazu sind am Drehpunkt (7) des Kippgelenks (8) in diesem Fall zwei Schwenkarme (9) angeordnet An diesen wirken über Führungsteile (10) die Druckfedern (11).For this purpose, two pivot arms (9) are arranged at the pivot point (7) of the tilting joint (8). The compression springs (11) act on these via guide parts (10).

Die gestrichelten Linien (13) mit den Gradangaben der Arbeitsstellung des Kippgelenks (8) zeigen in ihren Verlängerungen (14) die zugehörige Stellung der Schwenkarme (9). Die Auslegung der Schwenkarme (9), Druckfedern (11) und Führungsteile (10) muß je nach Art der restlichen Komponenten und je nach Problemstellung passend gewählt werden. Die Druckfedern (11) sind bei waagerechter Stellung des Kippgelenks (8) entspannt, bei senkrechter Stellung desselben unterstützen sie mit geringer Kraftverteilung die Standsicherheit.
Wird das Gerät abgestellt bzw. das Kippgelenk (8) mit dem Staubeauger (2) In eine Stellung von ca. 90° gebracht, wird ab ca. 60 - 80° Arbeitastellung ein Schalter (12) durch einen Schwenkarm (10) betätigt und dadurch das Gerät abgeschaltet.The dashed lines (13) with the degrees of the working position of the tilt joint (8) show in their extensions (14) the associated position of the swivel arms (9). The design of the swivel arms (9), compression springs (11) and guide parts (10) must be chosen according to the type of other components and the problem. The compression springs (11) are relaxed when the tilt joint (8) is in a horizontal position, and when it is in a vertical position they support stability with little force distribution.
If the device is switched off or the tilt joint (8) is moved to a position of approx. 90 ° with the jam eye (2), a switch (12) is actuated by a swivel arm (10) from approx. 60 - 80 ° working position and thereby the device is switched off.
