Vacuum cleaner mouthpiece

The innovation concerns a vacuum cleaner nozzle for optional vacuuming of textile floor or hard floor, the vacuum cleaner nozzle with a Fixed base plate for vacuuming on textile floor and one that can be raised A bristle ring is provided for vacuuming on hard floors.

There have long been known for household vacuum cleaners, vacuum cleaner mouthpieces, so-called combination nozzles, with which you can vacuum either on textile floors or on hard floors by using a fixed base plate or a movable bristle ring as an alternative.
With these nozzles, the movable bristle ring has to fulfill various functions when vacuuming hard floors.
It must bear the weight of the device, absorb the forces of movement, and absorb wear by means of suitable dimensions, ie in its original length.

It is extremely disadvantageous here that two criteria have to be met with regard to the last point, which work in opposite directions.
On the one hand, the bristle length must be large in order to absorb the wear and, on the other hand, an attempt must be made to bring the base plate as close as possible to the hard floor in order to maintain the suction power.
If one of the measures is carried out, the base plate is far away from the hard floor surface and the suction power is poor.
If the other measure is carried out, ie if the bristles are made shorter, the base plate can grind on the hard floor surface when the bristles are worn.

The task of the innovation is now to ei-τ ot.aubsaugermundstück the aforementioned Art to be trained in such a way that between the bottom plate and the hardwood surface the smallest possible distance, even if the bristle ring is worn is available*

According to the innovation, the task is solved by the features of claim 1. Advantageous configurations result from the features of claims 2 to 4.

A schematic section through a new $

Nozzle with retracted bristle ring, 1

Fig. 2:

a section according to FIG. 1 with the bristle ring extended;

Fig. 3:

an alternative to the nozzle with a spring-loaded bristle ring,

In Fig. 1, a vacuum cleaner nozzle housing 1 is shown in section, which, as is usual with normal so-called combination nozzles, has a fixed base plate 2 and an adjustable bristle ring 3. This The bristle ring 3 is attached to a bristle ring carrier 4 that can move up and down. Below this bristle ring carrier 4 is additional a plate 5 also movably arranged up and down, on which rolling elements 6 (two rolling elements 6 are shown) are arranged.

In Fig. 2, the mode of operation on a carpet 7 is shown. f-

In this case, the bristle ring carrier 4 including the bristle ring 3 and the plate 5 are pulled into the vacuum cleaner nozzle housing 1 and the solid base plate 2 rests on the carpet 7. \

If vacuuming is to be carried out on a solid surface 8, both the boron 1 stenkranzträger 4 as well as the plate 5 by a mechanism (this is not shown here). In this case, the plate 5 is locked after it has been extended and thus ensures that it is on the solid base 8 through the rolling body 6 for a constant distance between sub- ' Grund 8 and base plate 2.;.

The distance should be chosen as small as possible to the To increase suction power »The bristle ring support 4 is in this version not connected to the plate 5 and freely movable. That is, the The bristle ring 3 stands on the substrate 8 and can be together with the bristle ring carrier 4 move freely up and down.

Another embodiment is shown in FIG.

Here the bristle ring carrier 4 is connected to the vacuum cleaner nozzle housing 1 via springs 9. As a result, the bristle ring 3 is on the one hand pressed against the substrate 8 with a certain force, which may be higher than its weight, and on the other hand the system is damped so that the bristle ring carrier 4 does not start to vibrate.
This type of design can of course also be implemented in such a way that short springs are arranged between the bristle ring support 4 and plate 5, which take on the task of the springs 9. However, this design is not shown in the drawing.
