Support surfaces S are provided, which are arranged behind the suction channel 2 with respect to the working direction of the mouthpiece. Outside the mouthpiece sole, behind the same, a pair of rollers 4 is rotatably mounted as a support body on the suction nozzle 5 connected to the suction channel I. A brush strip 7 is arranged in a height-adjustable manner in front of the front working edge 6. The brush strip 7 is designed as a thread lifter 8 over part of its length. On the rear longitudinal side of the mouthpiece, a height-adjustable thread lifter 9, which extends over the entire length of the mouthpiece and only has recesses for the bearing surfaces 3, is provided.

{) The brush strip 7 is secured to a pivotally mounted in the rear portion of the mouthpiece housing 1 rocker 10th The adjustment of the rocker 10 and thus the height adjustment of the brush strip 7 takes place by means of an eccentric element 11 which is arranged non-rotatably on an adjustment shaft 14 and which has a first and second eccentric disc 12 and 13 which are arranged axially spaced apart on the adjustment shaft 14. A window-like opening 15 is punched on the rocker 10, at whose longitudinal edge adjacent to the rocker a first stop tab 16 is bent in the axial direction to the adjusting shaft 14, which is passed through the window-like opening 15.

On the opposite longitudinal edge of the window-like J opening 15 is opposite to the first stop tab

a second stop tab 17 bent axially. The two eccentric disks 12 and 13 are arranged on the adjusting shaft 14 in such a way that the first eccentric disk 12 with their eccentric cams 12a and 12b with the first stop tab 16 and the second eccentric disk 13 with their Eccentric cam 13a interacts with second stop bracket 17. The other arm of the rocker 10 can also be assigned such eccentric discs, so that a Canting of the rocker 10 as a result of one-sided actuation is avoided.

As FIGS. 5 and 7 show, two eccentric cams 12a and 12b are located opposite one another on the first eccentric disk 12 arranged. On the other hand, there is 13 on the second eccentric disk only one eccentric cam 13a is provided, which compared to the Eccentric cams 12a and 12b of the first eccentric disk 12 are offset by 90 ° in the circumferential direction. It is believed, that the adjusting shaft 14 is rotated by 90 ° when actuated. Corresponding to the illustration in FIG. 5 the first stop tab 16 rests on one flat part of the first eccentric disk 12. The rocker arm 10 can thus tilt downwards and the brush strip 7 protrudes downward from the mouthpiece housing 1. The brush y strip 7 is due to its own weight or given if also by the force of a spring acting on it on the surface to be vacuumed and can be raised against its own weight or against the spring force at any time, since between the lower longitudinal side of the window-like opening 15 and the two eccentric disc bed 12 and 13 connecting middle part 18 is a distance 19 through which an upward pivoting of the rocker 10 is possible will.

If the adjusting shaft 14 is designed as a step button 20 adjusting element on which with one on the Adjusting shaft 14 arranged, in the reverse direction of rotation free-running pinion 21 in meshing gear

- ίο - VPA 8% P 3 1 93 DE

segment 22 is formed, adjusted by 90 ° clockwise, then the eccentric cam 12a of the first eccentric disk 12 strikes against the first stop bracket 16 and presses the rocker 10 upwards. The brush strip 12 is thus raised and held out of engagement. With a further rotation by 90 °, the eccentric cam 13a of the second eccentric disk 13 strikes the second stop bracket 17 and presses the rocker 10 downwards. The brush strip J is thereby in its extended position and is held rigidly in this position by the eccentric cam 13a resting on the second stop bracket 17. After a further 90 "rotation, the rocker 10 is pushed up again by the eccentric cam 12b of the first eccentric disk 12 and the brush strip 7 is thus held in its raised position. The next 90 ° rotation returns to the starting position.

The adjustment by 90 ° each time the step button is actuated is achieved by a corresponding step-up ratio between the pinion 21 and the gear segment 22 connected to the step button 20. If the adjustment angle of the step button 20 is 45 °, for example, an adjustment angle of 90 ° is achieved on the adjustment shaft 14 by a ratio of 1: 2. In order to avoid an intermediate position of the adjusting shaft 14 when the step button 20 is not completely depressed, this is designed as a square 23 at at least one point and a leaf spring 24 is positioned on one side of the square 23. By means of this leaf spring 24, the adjustment shaft 14 is either switched back to the old position or switched to the new position if the step button 20 is insufficiently actuated, depending on whether the adjustment shaft has been adjusted by less or more than 45 ° when the step button 20 is actuated.

The height adjustment of the bearing surfaces 3 and the fill lifter 9 arranged behind the suction channel 2 can be carried out by means of a separate Adjusting elements or in combination with the

Adjusting shaft 14 take place. In the illustrated embodiment are on the adjusting shaft 14 further eccentric elements for adjusting the height of the support surfaces 3 and of the thread lifter 9 is provided. When the adjusting shaft 14 is actuated, these parts of the mouthpiece also become adjusted simultaneously with the brush strip 7.

The bearing surfaces 3 are provided with a rod-shaped or tubular extension 25, which is guided vertically in a pipe socket 26 formed on the mouthpiece housing 1 and serving as a receptacle. The pipe socket 26 can have a round V ) or square cross section. An opening 29 is provided in each of the vertical side walls 27 and 28 of the bearing surfaces 3, in the plane of which an eccentric 30 is arranged that is connected to the adjusting shaft 14 in a rotationally fixed manner and is assigned to the relevant bearing surface 3. The opening 19 is designed in such a way that the eccentric 30 comes to rest with its or stine eccentric cam 31 on the upper or lower edge of the opening 29, so that the bearing surfaces 3 are either raised or pressed down. In the illustrated embodiment, the eccentric cam 31 is designed as a double cam, that is, two cams immediately follow each other at a distance of 90 °. The sole of the mouthpiece no longer rests on the surface to be suctioned off, but is held at a small distance above this surface by the support surface ^ 3.

30th

The two vertical side walls 27 and 28 are over a Back surface 32 on which the tubular extension 25 is also integrally formed is connected to each other. In the area of the back surface protruding laterally from the tubular extension 25 32 rests on a bar 33 carrying the thread lifter 9. A hollow connector 34 is provided on the bar 33, which is pushed over the pipe socket 26. The pipe socket

thus also serves at the same time for the vertical guidance of the thread lifter 9 the mouthpiece housing 1 and with its other end 35b supporting compression spring 35 on the bar 33, the bar 33 held in contact with the back surface 32.

An axial projection 36 is also integrally formed on the bar 33, with which a single, likewise rotationally fixed, projection is also formed the adjusting shaft 14 connected eccentric cam 37 is assigned. This single eccentric cam 37 is opposite the eccentric 30 for the bearing surfaces 3 axially offset on the adjusting shaft 14 and is located in the circumferential direction the two eccentric cams 31 opposite. This ensures that in the one position in which the bearing surfaces 3 are adjusted down, the thread lifter 9 by the individual eccentric cam 37, which in this position then engages with the axial projection 36, is raised. In the other positions, the thread lifter 9 takes the position of the support surfaces 3, since it rests freely on the back surface 32 and thus the respective adjustment movement the support surfaces 3 with executes.

The various eccentric cams for operating the brush strips 7, the support surfaces 3 and the thread lifter 9 are, as already mentioned, on a common adjusting shaft 14 arranged. The appropriate arrangement of these eccentric cams in the circumferential direction can be used for setting the a fixed program should be provided for the individual parts. So are the mouthpiece described in the execution part The following four combinations of positions of brush strip 7, contact surfaces 3 and thread lifter 9 are possible: Position I:

a) Brush strip 7 resiliently extended, i.e. the brush strip can swing back up,

b) support surfaces 3 rigidly extended,

c) thread lifter 9 resiliently extended, i.e. against the force the compression spring can be moved upwards.

The individual positions of the Stavhsaugermundstückes are selected according to the nature of the respective area to be vacuumed, in order to with the respective nature to achieve the best possible cleaning result.

In the embodiment of a vacuum cleaner mouthpiece shown in FIGS. 11 to 14, axially adjustable Control slide is provided, the axial adjustment of which into a vertical adjustment via corresponding control slots the parts coupled with them is implemented.

A first control slide 40 is arranged above the brush strip 7 on the front side of the mouthpiece housing 1. As the view of this first control slide 40 shown in FIG. 12 shows that it has two control slots 41 spaced apart from one another in its longitudinal direction. the The control path of these control slots 41 runs between an upper and lower level 42 and 43. Through A, B, C and D are four control divisions of the control slide 40 indicated. In In control position A, the control path runs through a slot-like formation 44 of control slot 41 in FIG perpendicular direction. In each control slot 41 protrudes

because one connected to one of the brush strip 7 V support bracket 45 provided pin 46 so that the brush

• ι * ■ ·

- 14 - VPA WP 3 1 9 3 DE

strip 7 is suspended from the control slide 40. The brush strip 7 is guided in a shaft 47 of the mouthpiece housing 1 so that the pins 46 cannot slip out of the control slot 41.
5

In the control position A, the pins 46 are at the lower level 43 of the control path. The brush strip 7 is thus extended downward out of the mouthpiece housing 1. Their lower edge protrudes downwards over the level of the Mouthpiece sole in front. As a result of the elongated hole-like formation44

can move the pin 46 upwards, so that the ί 'Brush strip 7 when placing the mouthpiece on the Surface is pushed up and then as a result of its own weight or possibly also rests on the surface to be vacuumed by spring force and can spring back upwards.

In the control position B, the control path of the control slots 41 reaches the upper level 42. The brush strip 7 is thus raised when the control slide 40 is moved and no longer touches the surface to be vacuumed. The pin 46, which is adapted in its diameter to the width of the control slot 41, can now no longer execute vertical movements ζ, so that the brush bar is rigidly held in the respective position. 7

In control position C, the control path of the control slots runs 41 at the lower level 43. The brush strip 7 is in this position down from the mouthpiece housing extended. Since the pins 46 are guided without significant play in the control slots 41, the brush strip held rigidly in the extended position. The sole of the mouthpiece is thus opposite to the one to be sucked off by the brush strip 7 Surface slightly raised. This position of the brush strip 7 is selected when vacuuming hard floors.

- 15 - VPA WP 3 193 DE

In the control position D, the control path of the control slots 41 is guided back up to the upper level 42. In this control position the brush strip 7 is raised again as in the control position B. 5

A second control slide 48 (FIG. 14) is arranged behind the suction channel 2 in the mouthpiece housing, the two tax spaced apart in its longitudinal direction * slits 49 «Into these control slits 49, support straps 50 connected to the thread lifter 9 engage Pin 51 so that the thread lifter 9 is carried by the control slide () via 48. The control path of the control slots 49 also runs between an upper and lower level and 53, the control path through in the control position A a slot-like formation 54 of the control slot 49 again runs in the vertical direction. In the rest Control positions B, C and D, the control path of the second control slots 48 runs uniformly at the upper level 52, so that the thread lifter is always raised in these control positions, i.e. out of engagement with the surface to be suctioned. In contrast, in the control position Aist, the thread lifter is extended downwards, but can, as a result of the slot-like shape Training 54 of the control slots 48 move upwards. /, The thread lifter 9 is thus resiliently on the suctioned Surface on.

The support surfaces 3 are in this vacuum cleaner mouthpiece with a horizontally extending in the mouthpiece housing 1 Support bar 55 connected. On both longitudinal sides of this support bar 55 are each in the longitudinal direction of the support bar 55 control tracks 56 spaced from one another are formed. These control tracks 56 in turn run between one upper and lower height 57 and 58.
