  • Such a vacuum cleaner mouthpiece is known from DE-A-2 846 847.
  • the mouthpiece is tiltably attached to a pair of wheels so that the sole of the mouthpiece can rest freely on the surface to be cleaned.
  • the sole of the mouthpiece is raised in accordance with the height-adjustable brush strips on this mouthpiece sole by means of height-adjustable brush strips arranged on its two longitudinal sides and guided over the hard floor at a short distance.
  • a vacuum cleaner mouthpiece is also known in which a support surface is rigidly connected to a mouthpiece sole containing a suction channel.
  • a thread lifter is arranged such that it can be adjusted in height so that it can be brought into and out of engagement with the surface to be suctioned off. The thread lifter can be locked in either of the two positions.
  • skids are provided as a support surface on the two narrow sides of the mouthpiece within the contour of the mouthpiece housing.
  • a height-adjustable brush is arranged inside the mouthpiece housing behind the suction channel, which brush can be extended and retracted by actuating an adjusting lever. Through the actuation mechanism of the brush, a thread lifter attached in front of the suction channel can also be adjusted in height. The brush and thread lifter are adjusted in opposite directions.
  • the invention has for its object to design a vacuum cleaner mouthpiece of the type described above so that it can be adjusted according to the nature of the floor surface to be cleaned in such a way that the best possible cleaning effect is achieved.
  • a brush strip is provided only in front of the front working edge of the mouthpiece sole and a support surface or several separate support surfaces lying laterally to one another are arranged in a height-adjustable manner between the mouthpiece sole and the roller body, in addition that the thread lifter with or the support surfaces can be uncoupled and can be locked in a raised position relative to the support surface or surfaces by means of a locking member.
  • the suction behavior of the mouthpiece can be varied to a greater extent, so that good cleaning results can be achieved with one and the same mouthpiece on different floor surfaces.
  • the height adjustment of the brush strip arranged in front of the front working edge of the mouthpiece sole is achieved in a structurally simple manner in that the brush strip is arranged on a rocker arm pivotally mounted in the rear region of the mouthpiece housing, which can be pivoted by means of an adjusting element provided on the mouthpiece housing and can be locked in the respective position .
  • a simple, height-adjustable arrangement of the support surfaces and a decouplable connection of the thread lifter with these support surfaces is provided in that the support surfaces are guided vertically by means of a rod-shaped or tubular extension in a correspondingly designed receptacle of the mouthpiece housing and their height is adjustable by means of an adjusting member provided on the mouthpiece housing are that, furthermore, a bar carrying the thread lifter is held by spring force in abutment on a back surface of the support surfaces and can be lifted from this back surface against the spring force by means of a locking member which can be actuated from the outside.
  • the adjustment of the brush strip, the support surface and the thread lifter can be carried out with a single adjustment element if this is coupled to an adjustment shaft on which axially offset eccentric elements for adjusting the rocker and support surfaces and for locking the thread lifter are arranged.
  • the adjustment and locking of the brush strip in the respective position is carried out with simple means in that the rocker is assigned an eccentric element consisting of two axially offset eccentric disks, the first eccentric disk with a first stop plate arranged above the adjusting shaft on the rocker and the second eccentric disk interacts with a stop plate arranged below the adjusting shaft on the rocker.
  • a separate manufacture and assembly of the stop tabs can be avoided in that a window-like opening is provided on the rocker arm through which the adjusting shaft is guided, with a first stop bracket and protruding on one side of the rocker arm protruding from the edge of this opening above the adjusting shaft on the edge below the adjusting shaft there is a second protruding to the other side of the rocker Stop tab is bent.
  • the height adjustment and locking of the support surfaces at the respective height is achieved by assigning each support surface to an eccentric arranged on the adjusting shaft, which has two eccentric cams offset in the circumferential direction by 90 ° and in the plane of a vertical side wall connected to the respective support surface provided opening is located, the lower and upper boundary are designed as engagement points for the eccentric cam.
  • the thread lifter is uncoupled from the support surfaces in that a single eccentric cam on the adjusting shaft is axially offset relative to the eccentric for the support surfaces and is arranged in the circumferential direction opposite one of the two eccentric cams of the eccentric for the support surfaces and on the bar carrying the thread lifter one with the individual Eccentric cam interacting axial projection is provided.
  • a fixed assignment of the different positions of the brush strip, support surfaces and thread lifter is achieved in that the adjusting shaft can only be actuated in one direction of rotation by means of the adjusting element, that the first eccentric disc has two eccentric cams opposite each other by 180 ° and the second eccentric disc one by 90 ° with respect to the eccentric cams of the first eccentric cam offset cam that further, with respect to the direction of rotation of the adjusting shaft, the two eccentric cam of the eccentric for the bearing surfaces lag the eccentric cam of the second eccentric disk by 180 ° and 270 ° and the single eccentric cam forming the locking member for the thread lifter the eccentric cam of the second Eccentric disc lags 90 °.
  • the vacuum cleaner mouthpiece is pre-programmed for several different settings. The corresponding settings can be selected by actuating the adjustment element.
  • the taking of an intermediate position of the adjusting shaft in the event of incomplete depression of the adjusting element is prevented in that the adjusting shaft is designed as an equilateral square at one point on its circumference and a leaf spring lies flat on at least one side of the square.
  • a common guide for the height-adjustable support surfaces and the likewise height-adjustable thread lifter results from the fact that the rod-shaped or tubular extension of the support surfaces is guided inside in a pipe socket provided on the mouthpiece housing and the bar of the thread lifter with a hollow socket molded onto it on the outside of the pipe socket and a helical spring which is supported at one end on the mouthpiece housing and at the other end on the bar is arranged on the hollow connector.
  • the height adjustment of the brush bar, the thread lifter and the support surfaces can also be carried out by providing a first, assigned to the brush bar and a second, assigned to the thread lifter, each extending vertically, horizontally adjustable control slide, each of which at least has a control slot, the control path of which runs between an upper and a lower height, that in the control slot of the first control slide a pin provided on a support tab connected to the brush strip and in the control slot of the second control slide a pin provided on a support link connected to the thread lifter is that the support surfaces are also connected to a horizontally extending, vertically adjustable support bar, on which at least one control path extending between an upper and a lower height is provided, with which this is under spring force on a control cam of a third, horizontally adjustable control slide.
  • the different positions of the brush bar, thread lifter and support surfaces can be predetermined to one another by combining the three control spools by means of connecting parts to form a single control part, the first control spool on one and the second control spool on the other long side of the third Control spool are arranged and the control part is horizontally displaceably guided by provided on the connecting parts and on the mouthpiece housing, interlocking guide grooves and rails and adjustable by means of an adjusting element arranged on the mouthpiece housing.
  • the individual functional parts of the vacuum cleaner mouthpiece are each brought into a position which is determined by the geometry of the individual control slides connected to one another.
  • the control part can be adjusted by means of a sliding key connected to it or also by the fact that a rotary knob is provided which arranges one with one on the control part th rack interacting gear.
  • a tilt-proof arrangement of the support bar bearing the support surfaces results from the fact that on both sides of the support bar in the longitudinal direction of the support bar spaced control tracks are provided and a control cam is arranged on the third control slide for each control track.
  • control slots spaced apart in the longitudinal direction of the control slides are provided on the first and second control slides means that any further fastening and guide elements for the brush strip and the thread lifter are eliminated.

  • Two height-adjustable support surfaces 3 are provided on the mouthpiece, which are arranged behind the suction channel 2 with respect to the working direction of the mouthpiece.
  • a pair of rollers 4 is rotatably mounted behind it as a support body on the suction nozzle 5 connected to the suction channel 2.
  • a brush strip 7 is arranged such that it can be adjusted in height.
  • the brush strip 7 is designed as a thread lifter 8 over part of its length.
  • On the rear longitudinal side of the mouthpiece there is also a height-adjustable thread lifter 9 which extends over the entire length of the mouthpiece and which only has cutouts for the bearing surfaces 3.
  • the brush strip 7 is fastened to a rocker 10 which is pivotably mounted in the rear region of the mouthpiece housing 1.
  • the rocker arm 10 and thus the height adjustment of the brush strip 7 are adjusted by means of an eccentric element 11, which is arranged on a twist-proof shaft 14 and has a first and second eccentric disk 12 and 13, which are axially spaced on the adjusting shaft 14.
  • a window-like opening 15 is stamped on the rocker arm 10, on the longitudinal edge of which the rocker arm 10 is adjacent, a first stop tab 16 is bent in the axial direction of the adjusting shaft 14, which is guided through the window-like opening 15.
  • a second stop plate 17 is bent axially opposite to the first stop plate 16.
  • the two eccentric discs 12 and 13 are arranged on the displacement shaft 14 in such a way that the first eccentric disc 12 with its eccentric cams 12a and 12b cooperates with the first stop lug 16 and the second eccentric disc 13 with its eccentric cam 13a with the second stop lug 17.
  • Such eccentric discs can also be assigned to the other arm of the rocker 10, so that tilting of the rocker 10 as a result of one-sided actuation is avoided.
  • the brush strip 7 is due to its own weight or possibly also by the force of a spring acting on it on the surface to be extracted and can be lifted up 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 the two eccentric discs and 13 connecting the middle part 18 there is a distance 19 by which a swinging of the rocker 10 is made possible.
  • the adjustment shaft 14 is by means of an adjustment element designed as a step button 20, on which there is a toothed pinion 21 which is arranged on the adjustment shaft 14 and is freewheeling in the direction of rotation engaging gear segment 22 is formed, adjusted by 90 ° clockwise, then the eccentric cam 12a of the first eccentric disc 12 abuts the first stop plate 16 and presses the rocker 10 upward.
  • the brush bar 12 is thus raised and kept out of engagement.
  • the eccentric cam 13a of the second eccentric disk 13 abuts the second stop plate 17 and presses the rocker 10 downward.
  • the brush strip 7 is thereby in its extended position and is held rigidly in this position by the eccentric cam 13a abutting the second stop lug 17.
  • the rocker 10 is pressed upwards 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 starting position is reached again with the next 90 ° rotation.
  • the adjustment by 90 ° each time the pedal button 20 is actuated is achieved by a corresponding transmission ratio between the pinion 21 and the gear segment 22 connected to the pedal button 20. If the adjustment angle of the step button 20 is 45 °, for example, an adjustment angle of 90 ° on the adjustment shaft 14 is achieved by a ratio of 1: 2. In order to avoid an intermediate position of the adjusting shaft 14 when the kick button 20 is not fully depressed, it is designed as a square 23 at least at one point and a leaf spring 24 is brought into abutment on one side of the square 23.
  • the adjustment shaft 14 in case of insufficient operation of the Trittaste 20 either back into the old STEL - lung back or forwarded to the new position depending on whether the adjusting been more displaced than 45 ° when actuating the Trittaste 20 less or is.

  • the contact surfaces 3 are provided with a rod-shaped or tubular extension 25 which is guided vertically in a pipe socket 26 which is formed as a receptacle and is molded onto the mouthpiece housing 1.
  • the pipe socket 26 can have a round or square cross section.
  • an opening 29 is provided, in the plane of which an eccentric 30, which is connected to the adjustment shaft 14 and is associated with the relevant support surface 3, is arranged in a rotationally fixed manner.
  • the opening 29 is designed so that the eccentric 30 with its eccentric cam 31 comes to rest against the upper or lower edge of the opening 29, so that the bearing surfaces 3 are either raised or pressed down.
  • the eccentric cam 31 is designed as a double cam, i. H.
  • the two vertical side walls 27 and 28 are connected to one another via a back surface 32, on which the tubular extension 25 is also molded.
  • a bar 33 carrying the thread lifter 9.
  • a hollow socket 34 is provided, which is pushed over the pipe socket 26.

  • an axial projection 36 is formed on the strip 33, to which a single eccentric cam 37, which is also connected non-rotatably to the adjusting shaft 14, is assigned.
  • This single eccentric cam 37 is axially offset relative to the eccentric 30 for the bearing surfaces 3 on the adjusting shaft 14 and lies opposite one of the two eccentric cams 31 in the circumferential direction. This ensures that in the one position, in which the bearing surfaces 3 are adjusted downward, the thread lifter 9 is raised by the individual eccentric cam 37, which in this position is then in engagement with the axial projection 36. In the other positions, the thread lifter 9 assumes the position of the support surfaces 3, since it rests freely on the back surface 32 and thus carries out the respective adjustment movement of the support surfaces 3.
  • the individual positions of the vacuum cleaner mouthpiece are selected according to the nature of the surface to be vacuumed, in order to achieve the best possible cleaning result with the respective nature.
  • Position 11 allows vacuuming with minimal pushing force and position 111 is used for vacuuming hard surfaces.

  • Four control positions of the control slide 40 are indicated by A, B, C and D.
  • the control path runs in the vertical direction through a slot-like configuration 44 of the control slot 41.
  • a pin 46 provided on a support bracket 45 connected to the brush strip 7 protrudes, so that the brush strip 7 is suspended on 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.
  • the pins 46 are at the lower height 43 of the control track.
  • the brush strip is thus extended downwards out of the mouthpiece housing 1. Your lower edge protrudes downwards beyond the level of the mouthpiece sole.
  • the pins 46 can deflect upward, so that the brush strip 7 is pushed upwards when the mouthpiece is placed on the surface to be extracted and then rests on the surface to be extracted due to its own weight or, if appropriate, also by spring force and spring back upwards can.
  • control position B the control path of the control slots 41 reaches the upper height 42.
  • the brush strip 7 is thus raised when the control slide 40 is moved and no longer touches the surface to be extracted.
  • the pin 46 the diameter of which is adapted to the width of the control slot 41, can now no longer perform vertical movements, so that the brush strip 7 is held rigidly in the respective position.
  • the control path of the control slots 41 runs at the lower height 43.
  • the brush strip 7 is extended downward from the mouthpiece housing. Since the pins 46 are guided in the control slots 41 without any significant play, the brush strip 7 is held rigidly in the extended position. The soleplate sole is thus raised somewhat by the brush strip 7 in relation to the surface to be suctioned off. This position of the brush strip 7 is selected when vacuuming hard floors.
  • control position D In the control position D, the control path of the control slots 41 is guided upwards again to the upper height 42. In this control position, the brush strip 7 is raised again as in the control position B.
  • a second control slide 48 (FIG. 14), which has two control slots 49 spaced apart from one another in its longitudinal direction, is arranged in the mouthpiece housing 1 behind the suction channel 2.

On both long sides of this support bar 55 are each in the longitudinal direction of the support bar 55 spaced apart control tracks 56 formed. These control tracks 56 in turn run between an upper and lower height 57 and 58. Above the support bar 55 there is a third control slide 59, on which control cams 60 associated with the control tracks 56 of the support bar 55 are formed.
