Definitions

  • the invention relates to a vacuum cleaner mouthpiece which is pivotally articulated with its housing outside the effective suction surface of its mouthpiece sole on a roller support body arranged in relation to the working direction behind the mouthpiece sole and resting on the surface to be cleaned, and which has at least one height-adjustable brush strip on which mouthpiece furthermore at least one thread lifter is arranged.
  • Such a vacuum cleaner mouthpiece is known from DE-OS 28 46 847.
  • 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 mouthpiece with its sole is pressed against the surface to be suctioned in accordance with the negative pressure prevailing at this mouthpiece sole, so that a correspondingly high pushing force results.
  • the soleplate sole can be raised by means of height-adjustable brush strips arranged on its two long sides and guided over the hard floor at a short distance. In addition to this lifting of the mouthpiece sole, there is no further possibility in the known vacuum cleaner mouthpiece to bring it into a suction position adapted to the particular nature of the base surface to be extracted.
  • 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 by providing a window-like opening on the rocker arm through which the adjusting shaft is passed, with the first stop tab and projecting on one side of the rocker arm on the edge of this opening above the adjusting shaft a second stop tab protruding to the other side of the rocker is bent on the edge below the adjusting shaft.
  • each support surface is assigned 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 edge are designed as engagement points for the eccentric cam.
  • the thread lifter is uncoupled from the support surfaces by a single one on the adjusting shaft Eccentric cams axially offset from the eccentric for the support surfaces and 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 an axial projection cooperating with the individual eccentric cams is provided.
  • a fixed assignment of the various positions of the brush bar, support surfaces and the thread lifter is achieved in that the adjusting means of the adjusting element is operable only in one direction of rotation, that the first eccentric disk two 180 0 opposite eccentric cam and the second eccentric disc a by 90 ° with respect to the eccentric cam of the first eccentric cam offset cam, that further, with respect to the direction of rotation of the adjusting shaft, the two eccentric cams of the eccentric for the bearing surfaces lag the eccentric cam of the second eccentric disk by 180 ° and 270 ° and the individual eccentric cam forming the locking member for the thread lifter follows 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 bracket connected to the brush strip and in the control slot of the second control slide a pin provided on a bracket 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 track running between an upper and a lower height is provided, with which this rests 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 button connected to it or also by the fact that a rotary knob is provided which has a toothed ring which interacts with a rack arranged on the control part.
  • 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.
  • the housing of a vacuum cleaner mouthpiece is designated, which has a suction channel 2 on its mouthpiece sole.
  • 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.
  • On the opposite longitudinal edge of the window-like opening 15 is opposite to the first stop tab 16 a second stop tab 17 is axially bent.
  • the two eccentric discs 12 and 13 are arranged on the adjusting 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 disks 12 and 13 connecting the middle part 18 there is a distance 19 by which the rocker arm 10 can be pivoted upwards.
  • the adjustment shaft 14 is by means of an adjustment element designed as a step button 20, on which a gearwheel which is arranged on the adjustment shaft 14 and which is free-running in the reverse direction of rotation is in engagement segment 22 is formed, adjusted by 90 ° clockwise, then the eccentric cam 12a of the first eccentric disk 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 Trit button 20 is actuated is achieved by a corresponding transmission ratio between the pinion 21 and the gear segment 22 connected to the Trit 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 translation 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 at least one point and a leaf spring 24 is brought into abutment on one side of the square 23.
  • the adjustment shaft 14 is either switched back to the old position or to the new position if the actuation of the step button 20 is insufficient, depending on whether the adjustment shaft has been adjusted by less or more than 45 ° when the step button 20 has been actuated.
  • the height adjustment of the support surfaces 3 and the thread lifter 9 arranged behind the suction channel 2 can be done by means of separate adjusting elements or also in combination with the Adjustment shaft 14 take place.
  • further eccentric elements for adjusting the height of the support surfaces 3 and the thread lifter 9 are provided on the adjusting shaft 14. When the adjusting shaft 14 is actuated, these parts of the mouthpiece are thus simultaneously adjusted with the brush strip 7.
  • 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 adjusting shaft 14 and is associated with the relevant contact surface 3, is arranged.
  • 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.e. two cams immediately follow one another at a distance of 90 °.
  • the support surfaces 3 When the support surfaces 3 are pressed downwards, they are adjusted downwards from the level of the mouthpiece sole and protrude above this level. The mouthpiece sole is therefore no longer on the surface to be suctioned off, but is kept at a short distance above this surface by the contact surfaces 3.
  • 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.
  • the pipe socket 26 thus at the same time also serves for the vertical guidance of the thread lifter 9.
  • the bar 33 is held in abutment on the back surface 32 by a compression spring 35 which is supported at one end 35a on the mouthpiece housing 1 and at the other end 35b on the bar 33.
  • 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.
  • axially adjustable control slides are provided, the axial adjustment of which is implemented via corresponding control slots in a vertical adjustment of the parts coupled to them.
  • a first control slide 40 is arranged above the brush strip 7 on the front of the mouthpiece housing 1.
  • this first control slide 40 shown in FIG. 12 shows, it has two control slots 41 spaced apart in its longitudinal direction.
  • the control path of these control slots 41 runs between an upper and lower height 42 and 43.
  • 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 brushes bar 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 7 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 suctioned off and then rests on the surface to be suctioned off due to its own weight or possibly also by spring force and can spring back upwards .
  • 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.
  • control position C 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 the control path of the control slots 11 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.
  • pins 51 provided on the support tabs 50 connected to the thread lifter 9 engage, so that the thread lifter 9 is carried by the control slide 48.
  • the control path of the control slots 49 likewise runs between an upper and lower height 52 and 53, wherein in the control position A the control path again runs in the vertical direction through an elongated hole-like configuration 54 of the control slot 49.
  • the control path of the second control slots 48 runs uniformly at the upper height 52, so that the thread lifter is always raised in these control positions, i.e.
  • the contact surfaces 3 are connected to a support bar 55 which extends horizontally in the mouthpiece housing 1.
  • control tracks 56 are formed which are spaced apart from one another in the longitudinal direction of the support bar 55. 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.
  • Coil springs 62 are arranged between the support bar 55 and a wall 61 fixed to the housing the support bar 55 with its control tracks 56 pressed against the control cam 60, so that depending on the course of the control tracks 56, the support bar 55 and thus the bearing surfaces 3 are moved up and down.
  • control tracks 56 run at their upper height 57.
  • the support bar 55 is thus pressed down by the control cams 60 in these control positions.
  • the contact surfaces 3 are extended downwards in these control positions and are held rigidly in this position by the control cams 60 resting on the control tracks 56.
  • control tracks 56 run at their lower height 58.
  • the support bar 55 is now pressed upward by the coil springs 62, so that the control tracks 56 continue to bear against the control cams 60.
  • the contact surfaces 3 are thus raised and no longer lie on the surface to be extracted.
  • the three control slides 40, 48 and 59 can each be separately displaced in the mouthpiece housing and thus the brush bar 7, the thread lifter 9 and the contact surfaces 3 can be adjusted in height independently of one another.
  • the three control slides are connected to a single control part by connecting parts 63 and 64.
  • the first control spool 40 is coupled via the connecting part 63 to the one long side of the third control spool 59.
  • the connecting parts 63 and 64 have guide grooves 65 and 66, with which they are plugged onto corresponding guide rails 67 and 68 provided on the mouthpiece housing 1.
  • the complete control part is slidably guided in the horizontal direction and thereby enables the horizontal adjustment of the three control slides 40, 48 and 59.
  • a knob 69 is arranged on the mouthpiece housing 1, which is provided with a ring gear 70. With this ring gear 70, the rotary knob 69 engages in a rack 71 provided on the control part. The rotary movement of the rotary knob 69 is thereby converted into a sliding movement of the control part.
  • the difference between the upper and lower heights 42, 43; 52, 53 or 57, 58 of the scattering slots 41 and 49 or of the control tracks 56 can be the same or different. Likewise, different upper or lower heights can be selected in the different control positions A to D for the individual control positions.
