Definitions

  • the invention relates to a vacuum cleaner mouthpiece according to the preamble of claim 1.
  • Such a vacuum cleaner mouthpiece is known from DE-PS 30 09 648.
  • the body is pivoted about its tilting axis by the forces acting on it when sliding over the surface to be suctioned, so that it lies flat on the surface to be suctioned regardless of the position of the mouthpiece housing.
  • the invention is based on the object of forcibly pivoting the mouthpiece body in a vacuum cleaner mouthpiece in such a way that at least one working edge is increasingly used in the corresponding direction of movement.
  • the connecting part coupled to it Due to the forces exerted on the actuating member when the mouthpiece is moved back and forth, the connecting part coupled to it is moved axially back and forth between two end positions. By this axial movement of the connecting part, the mouthpiece body is forcibly tilted, so that, depending on the position of its tilting axis, at least its one working edge is pressed more strongly against the surface to be extracted.
  • the connecting part can be designed as a rigid rod or as a toggle joint.
  • the movement of the connecting part in the corresponding direction necessary for tilting the mouthpiece body is carried out via the actuating member.
  • the forcible tilting of the mouthpiece body with the parts necessary for the function of the mouthpiece is achieved in that a suction nozzle forming the suction connection is rotatably connected at one end above the tilting axis of the mouthpiece body and at its other end an articulated connection with a suction tube serving as an actuator, that furthermore the articulated connection is movably connected to the support body by means of a horizontal slot guide or at least one horizontal component.
  • the mouthpiece body can be tilted about an axis lying outside its vertical center, the front working edge is tilted towards the surface to be extracted in both directions of movement. It is particularly advantageous that the tilt axis is behind the vertical center with respect to the front of the mouthpiece. In this way, when the mouthpiece body is tilted, the forces acting differently in both directions of movement are taken into account, so that an equally good suction result is achieved in both directions.
  • the tilt angle of the mouthpiece body can be changed by adjusting the length of the slot guide.
  • the working edge in question Due to the forced inclination of the mouthpiece body, the working edge in question is pressed into the carpet pile, thereby improving its effect. At the same time, the opposite working edge is raised accordingly, so that more air can flow in and the dirt loosened from the effective working edge can also be safely removed. This also reduces the pushing force, which is essentially determined by the rear edge in the direction of movement.
  • the forced tilting of the mouthpiece body depending on the direction of movement of the mouthpiece is there according to a further embodiment of the invention in a structurally simple manner achieved by a suction pipe forming the suction connection, consisting of two telescopically displaceable pipe parts, is articulated with its one pipe part on the mouthpiece body and with its other pipe part on a suction pipe serving as an actuator, that the suction pipe and the articulated other pipe part are guided axially movably on the support body are and that a linkage is provided as a connecting part, which is coupled at one end to these axially movable parts and is rotatably connected to the other end above the tilting axis of the mouthpiece body.
  • a simple assembly of the rod is achieved in that it consists of a U-shaped wire bracket, which is clamped with its yoke into a groove provided on the other tube part and the leg ends of which are bent at right angles and into a slot provided in each case in the molded ears on the mouthpiece body intervention.
  • a vacuum cleaner mouthpiece with a vacuum cleaner mouthpiece is designated that has a tiltable mouthpiece body. Furthermore, the mouthpiece 1 is provided with a support body 3 which rests on the surface to be suctioned off and carries the entire mouthpiece. With the mouthpiece body 2, a suction nozzle 4 is movably connected at one end 4a, for example via an elastic piece of hose. With its other end 4b, the suction nozzle 4 is pivotably articulated via a hinge connection 5 to a suction pipe 6 forming the actuating member. An extension part 7 is provided on the suction pipe 6, which is movably connected by a slot guide to a tab 8 arranged on the support body 3.
  • the slot guide is formed by an elongated hole 9 formed on the extension part 7 and a pin 10 engaging in it and arranged on the tab 8.
  • the extension part 7 is guided in a straight line by guide pieces 11 formed on the tab 8, so that the extension part 7 cannot carry out a pivoting movement.
  • the mouthpiece body 2 is pivotably mounted on a cross member 12 connected to the support body 3, which crosses around the mouthpiece body 2 in a forked manner.
  • a rod 13 is articulated with its one end 13a as a connecting part, which is rotatably attached to the extension part 7 with its other end 13b.
  • the extension part 7 is moved up and down due to the slot guide. This leads to an axial displacement of the rod 13, whereby the mouthpiece body 2 is pivoted about its tilt axis 14.
  • the connecting part pivoting the mouthpiece body 2 is designed as a toggle joint 21.
  • This toggle lever joint is articulated on the housing of the mouthpiece body 2 with one end 21a and on the support body 3 with its other end 21b.
  • stops 22 fixed to the housing, the Ver travel of the toggle lever 21 and thus also the pivoting angle of the mouthpiece body 2 is limited.
  • the toggle joint 21 is coupled to the suction pipe 6 via a connecting arm 23.
  • the toggle joint 21 is moved from its one end position to the other end position and the mouthpiece body 2 is pivoted accordingly, as is shown schematically in FIGS. 3 and 4.
  • FIG. 5 differs from the embodiments shown in FIGS. 1 and 2 in that no separate structural parts are required for executing the pivoting movement of the mouthpiece body 2.
  • the pivoting movement of the mouthpiece body 2 is brought about by a suction nozzle 25 which is articulated at one end 25a on the mouthpiece body 2 by means of an articulation point 24 and which at its other end 25b via the articulation 5 with the Suction pipe 6 is coupled.
  • the axis of rotation 26 of the articulation 5 is slidably guided in a horizontal slot 27, which is provided in the tab 8 connected to the support body 3.
  • the ends of the slot 27 each form the limit stops for the adjustment path of the axis of rotation 26 and thus again for the adjustment angle of the mouthpiece body 2.
  • the axis of rotation 26 accordingly slides back and forth in the slot 27 between the two slot ends . This axial movement is converted into a corresponding pivoting movement of the mouthpiece body 2 via the suction nozzle 25.
  • the mouthpiece body 2 is connected by suction to a suction pipe 6 via a suction nozzle consisting of two pipe parts 28 and 29.
  • One tube part 28 is inserted at one end 28a into the other tube part 29, so that the two tube parts 28 and 29 can be telescopically displaced relative to one another.
  • One tubular part 28 is also connected to a support plate 30, which in turn is attached to the support body 3. So that the one pipe part 28 is rigidly attached.
  • the one tube part 28 is articulated to the mouthpiece body 2, the axis of this joint being in the tilting axis 14 of the mouthpiece body 2.
  • the other tube part 29 is rotatably connected to the suction tube 6.
  • Laterally projecting guide pins 31 are integrally formed on the other tube part 29, through which the other tube part 29 and the suction tube 6 connected to it are movably guided in horizontally extending guide slots which are provided in support blocks 33 fastened to the support body 3.
  • the displacement path of the suction pipe 6 and the other pipe part 29 is limited by means of a nipple 35 formed on the outer wall of the other pipe part 29 and engaging in a limiting slot 34 provided on the support plate 30.
  • the horizontal movement of the suction pipe 6 and the other pipe part 29 into a tilting movement of the mouthpiece body 2 takes place via a linkage consisting of a U-shaped wire bracket 36.
  • the wire bracket 36 With its yoke 36a, the wire bracket 36 is clamped into a groove 37 formed on the other tube part 29.
  • the wire bracket 36 is thus held on the other tube part 29 without further fastening parts.
  • the leg ends 38 of the U-shaped wire bracket 36 are bent at right angles and each engage in a slot 39 which is provided in ears 40 formed on the mouthpiece body 2. In this way, a rotatable connection between the leg ends 38 and the mouthpiece body 2 is achieved.
  • the mouthpiece body 2 is tiltably supported by means of pivot pins 41 which engage in corresponding bearing bores 42 provided in the side walls 43 of the mouthpiece housing 44.
  • the suction pipe 6 and the other pipe part 29 are moved back and forth in accordance with the distance predetermined by the limiting slot 34. These back and forth movements are converted into corresponding tilting movements of the mouthpiece body 2 via the U-shaped wire bracket 36 connected to the other tube part 29.
  • the front working edge 16 or 18 in the respective direction of movement is inevitably pressed into the carpet pile 19, so that the relevant working edge 16 or 18 grips deeper layers of the carpet pile 19 and loosens the dirt deposited there. Since the pivoting of the mouthpiece body 2 raises the working edge, which is in each case in engagement with the carpet pile 19, above the surface of the carpet pile, more air can flow into the suction opening 20 of the mouthpiece body 2, so that the through the working edge 16 or 18 loosened dirt can also be safely removed.
  • an adjustment possibility for the adjustment path of the connecting part (rod 13, toggle joint 21, suction nozzle 25, wire bracket 36) and thus for the pivoting angle can be provided.
  • the depth of penetration of the working edge 16 or 18 can be adjusted, so that the effect of the vacuum cleaner mouthpiece 1 can be adapted to the respective carpet type.
