Definitions

  • the invention relates to a suction mouthpiece according to the Preamble of the first claim.
  • a suction mouthpiece of this type (EP 0 338 513 A2) is a base plate made of plastic which auxiliary elements can be rotated like a suction channel stored roller brush, one parallel to the suction channel extending sealing strip and wheels and the like corresponding brackets are provided.
  • For the Sealing strip is located in the bottom plate essential U-shaped groove leading to the surface to be machined is open and at the relevant ends of the groove flanks Has retaining webs.
  • the invention is based, with one Suction mouthpiece according to the preamble of the first claim Take measures by which the necessary Retaining webs in one only parallel to the level of the Bottom plate split mold can be made can.
  • the retaining webs are only in the area generated by breakthroughs in the groove base, the Undercut edges created by a tool core pin which is firmly attached to the injection mold part, with which the back of the base plate is molded.
  • the Groove bases and those to the working side of the base plate Pointing flank parts of the retaining webs are by the the working side of the base plate forming tool part educated.
  • their inguinal foot is largely in cross section hat-shaped, the narrower hat bow the Groove bases and the widened hat brim of the open Side of the groove is facing.
  • the transition between arches and brim has chamfers so that the hat bow can be freely inserted between the retaining webs can and at first a stable assembly position is reached.
  • By pressing down the groin foot is under appropriate compression of the brim in the area of Retaining bridges the hat brim between the retaining bridges pressed through.
  • the brim then expands again and reaches under the bridges while the hat bow grips between support ribs, the opposite, extending parallel to each other over the length of the groove Groove flanks are formed in the area of the groove base webs. This also prevents the hat bow from being installed Secured transverse adjustment and thus the sealing strip overall held stable in the groove.
  • Lugs may be provided in the guide slots same as the retaining webs of the groove by one from the back of the base plate in the concerned Bearing slot engaging on the back forming injection mold fixed core part being represented.
  • the locking lugs opposite the closed as a bearing surface only for the bearing axles serving the wheel axles a separation of the injection mold in the plane of the Base plate required.
  • the invention is based on the sketches of a Embodiment explained in more detail.
  • a suction mouthpiece for a vacuum cleaner has one Base plate 1, on which auxiliary elements as a Suction channel 2 with associated thread lifter 3, sealing strips 4, Wheels 5 and support surfaces 6 or support bales 7 are provided are.
  • the wheels 5 are partially immersed in Wheel arches 8, in which the wheels with their wheel axles 9 are supported and fixed at both ends.
  • the Base plate 1 is made of plastic in a spray or Press tool made, the suction channel 2, the Wheel arches 8 and groove holders 10 for sealing strips 4 or Slits 11 are integrally formed for the wheel axles.
  • the bearing slots 11 run perpendicular to the one shown Bottom of the base plate 1 into the plane rear, top side 28 during operation the bottom plate 1 and are U-shaped both when viewed from above on the base plate 1 as well as in the side view according to 3, the respective bearing slot 11 in the slot depth an end bearing surface 12 for End of the wheel axis 9 has.
  • an upstream locking lug 13 which is radial to the wheel axis 9 is directed and as a securing means for the wheel axle 9 serves in the assembled operating position.
  • the wheel arches 8 Lifting flanks 15 assigned, which point under a Angle 16 to the level of the base plate 1 are inclined so that compared to the remaining distance between the wheel circumference and wheel arch results in increased distance.
  • a flank screwdriver 17 in the wheel arch 8 are inserted so that when tipping over the between the lifting flank 15 and the plane of the Base plate 1 formed edge 18 by the cutting edge 19 of the Screwdriver a lifting torque to the extent of the concerned wheel can be exercised, the Main force component to the open side of the concerned Slot guides 11 is directed.
  • the wheel in question can thus against the locking action of the locking lugs 13th lever out the associated bearing slots 11 again.
  • the wheel axles 9 parallel to the longitudinal direction of the base plate 1 or Suction channel 2 and in the skin pusher direction at a distance are offset from each other, then the Lifting flanks 15 are arranged so that they are each towards the center the bottom plate 1 run out. It results in a simplified access during disassembly as well as Possibility to get the wheels as close as possible to the concerned Use the longitudinal edges of the base plate 1.
  • the locking lugs 13 To the with the locking lugs 13 bearing slots 11 in one only pullable in the longitudinal direction of the bearing slots 11 To be able to form the mold, the locking lugs 13 axially next to the end bearing surface 12 arranged and the bearing slot 11 in the demolding direction only in the area of the latch 13 to the rear 28 of the Base plate 1 designed open. It is therefore enough Forming tool with drivable cores.
  • the sealing strips 4 provided in the base plate 1 molded grooves 10 extend into Main slide direction laterally next to the support surface 6 in essentially parallel to the suction channel 2.
  • the grooves 10 are formed essentially U-shaped in the longitudinal direction and open to the working level of the floor slab. Of the Groove bottom points through openings 22 toward the rear 28 on, so that groove base support webs 23 remain on which the last foot 24 of the sealing strip 4 is supported.
  • the opposing flanks 25 Retaining web sections 26 are formed, each for opposite groove flank point and as a counter bearing serve for the last foot 24. They extend in Longitudinal direction of the groove 10 only at most over one respective assigned opening 22 corresponding length, do not use the in a vertical projection Groove bases 23 over.
  • 24 is a thin, soft, elastic sealing lip 27 integrally formed, the free lip edge to over the plane determined by the edges of the suction channel 2 and in particular over the plane determined by the wheels 5 protrudes.
  • This sealing strip 4 largely prevents the free inflow of air from the rear long edge 21 forth, as that also causes the increased support surface 6.
  • To the Inserting the sealing strip 4 requires its strip foot 24 only on the open side of the groove 10 or on the Restraint webs 26 placed and under elastic Deformation between the retaining webs 26 in the Groove 10 to be pushed in. The retaining webs 26 then prevent the inadvertent falling out Sealing strip from the groove 10. Need for disassembly only one end of the sealing strip 4 in question of a tool to be levered out of the groove 10 in order to then by hand or with pliers from the rest Part of the groove 10 to be pulled out.
  • the sealing strip 4 To the rest of the sealing strip 4 in a simple manner to be able to execute are within the groove 10 of the Groove bases 23 outgoing and to the open side of the groove 10 directed support ribs 30 to itself opposite, parallel to each other over the length of the Groove 10-reaching groove flank webs 29 are formed.
  • the Support ribs 30 extend only over a part the height of the groove 10. Accordingly, the last foot 24 approximately hat-shaped in cross section, the narrower hat arch 24.1 facing the groove base webs 23 engages between the support ribs 30 while the hat brim 24.2 directly on the groove flanks 25 adjacent to the Retaining bars 26 abuts after moving into this area the support ribs 30 do not extend.
