Definitions

  • the invention relates to a suction mouthpiece according to the preamble of the first claim.
  • a known suction mouthpiece of this type (DE-OS 28 46 847) has a nozzle body, which is equipped with a suction pipe piece articulated thereon via a further pivotable pipe joint with a suction nozzle for connection to a vacuum cleaner.
  • the suction nozzle is additionally provided with a pipe joint that can be rotated about the pipe longitudinal axis.
  • the suction nozzle part coupled to the suction pipe piece is provided with impellers which are arranged on opposite sides and roll in the main sliding direction behind the nozzle body on the floor surface to be extracted.
  • the invention has for its object to take a suction mouthpiece according to the preamble of the first claim measures by which a closed structure is achieved.
  • the pipe joints assigned to the suction pipe piece are protected by a cover cap which is fitted onto this suction pipe piece and which at the same time also overlaps the laterally projecting impellers.
  • the cover cap forms a protection for the sealing lips necessary on the pipe joints, in particular the nozzle body in the area of the pipe joint provided there can be made so low that the sealing lip can be moved to the area in which there is otherwise the risk of bumping against furniture edges or Like. Is given.
  • the covering of the wheels has the effect that, especially when vacuuming under upholstered furniture with fringes or fabric shelves, the risk is reduced that these decorative elements get caught in the gap between the wheels.
  • the cover cap has to hold it in the direction of the pivot axis on opposite side edges, preferably side cheeks which are perpendicular to the pivot axis of the pipe joint and carry latching means which are releasably engaged with counter-catches on the suction pipe piece.
  • the suction pipe section can have adapted wall parts which are oriented vertically upward and which bear the counter-catches.
  • the top of the cap is preferably rectangular and of such a width that it overlaps the outer end faces of the impellers and engages with the side cheeks in front of the end faces of the impellers.
  • a suction mouthpiece for a vacuum cleaner has a nozzle body 1 which is to be guided with a mouthpiece plate 2 over a bottom surface 3 to be suctioned off.
  • a mouthpiece plate 2 Provided in the base plate 2 is an upwardly directed suction channel 4 which runs transversely to the main direction of displacement and which in the middle of its longitudinal extent merges into an essentially upwardly directed channel socket 5.
  • a suction pipe piece 6 engages laterally from above in the channel connection piece 5, where it is pivotably mounted about a pivot axis 7 and engages in the channel connection piece in the manner of a pipe swivel joint.
  • the free end of the suction tube piece 6, which dips into the duct connection, is designed as a sealing lip 8, which is formed in particular on the edge which runs parallel to the pivot axis 7 and is adjacent to the upper side of the nozzle body 1.
  • the other end of the suction pipe section 6 protrudes rearward beyond the main direction of travel beyond the nozzle body 1 and merges there into a further pipe swivel joint 9, which can also be pivoted to a limited extent about its assigned axis of rotation 10.
  • the pivot axes 7 and 10 run parallel to each other.
  • the suction nozzle 11, which is coupled to the suction pipe piece 6 via the pipe swivel joint 9, is provided on both sides with impellers 12 which are mounted in the same axis as the pipe swivel joint 9 and roll freely on the floor surface 3 to be cleaned.
  • the impellers 12 absorb forces which are exerted by a suction pipe to be connected to the suction nozzle 11, to be guided by hand, or a vacuum cleaner to be connected to it. Due to the interposition of the tubular swivel joint 9, these forces have practically no effect on the nozzle body 1.
  • a cover cap 14 is provided which is adapted to the contour of the cutout 13 and can be detachably placed on the side of the suction tube piece 6 lying in the operating position from above and fixed thereon.
  • the cover cap 14 has, at its side edges opposite in the direction of the pivot axis, side cheeks 15 which are perpendicular to the pivot axis 7 and carry latching means 16, which have counter latches 17 are releasably engaged or to be brought into place on holding bars 17.1 on the suction pipe section 6
  • the top of the cover cap 14 is rectangular and has a width which corresponds at least to the distance between the outer end faces of the impellers 12.
  • the cover cap 14 extends from the nozzle body 1 over the center of the impellers 12 and at the same time covers the upward gap of the tubular swivel joint 9.
  • the side cheeks 15 engage in front of the end faces of the impellers 12, but cover them to the side only to a fraction.
  • the covering cap 14 engages in the cutout 13 with its edge 18 running parallel to the pivot axis 7, engages under an adjacent edge 13.1 of this cutout 13 and, when the suction pipe piece 6 is pivoted relative to the nozzle body 1, dips under the relevant front edge 13.1 or the top 13.2 of the hood covering the nozzle body 1 upwards.
  • the sealing lip 8 which is located approximately at the same height with this edge, is also protected by the cover cap 14 against damage which may occur due to bumping against furniture edges or the like during suction.
