Definitions

  • the invention relates to an arrangement for releasable connection a suction nozzle with the suction opening of a vacuum cleaner according to the preamble of claim 1.
  • the invention is therefore based on the object of an arrangement of the generic type Kind in such a way that one of both possible Longitudinal tolerances of the parts to be sealed against each other as well as unaffected by these tensile forces Sealing of the coupled parts is achieved.
  • sealing element protrudes in the axial direction in the between the tubular end of the suction nozzle and the suction opening of the vacuum cleaner existing annular gap. Because the sealing element is nowhere in the axial direction rests with an axial movement of the suction nozzle or, in the case of axial length tolerances, the sealing effect of the sealing element in no way affected. The sealing element is only in the axial direction on the wall moved along the suction opening without losing its sealing effect to be influenced.
  • a good sealing effect is achieved by using a sealing lip on the tubular part of the extension an oblique collar is formed on the outside.
  • the extension provided on the locking element can also be used to lock the locking element, in that on the inside of the tubular extension a lockable on the tubular end of a pipe socket Locking element is provided.
  • FIG. 1 With 1 is a wall part of a hint shown Called vacuum cleaner housing.
  • the Suction opening of the vacuum cleaner On the wall part 1 is the Suction opening of the vacuum cleaner provided.
  • a suction nozzle 3 At this suction opening 2 is a suction nozzle 3 connected to a suction hose connectable.
  • the suction opening 2 thus forms one with the Suction nozzle 3 connectable other pipe socket.
  • One suction port 3 has a tubular one which can be inserted into the suction opening 2 End 4 on that to a certain axial length of a tube extension 5 of the suction nozzle 3 with a radial distance is surrounded. This results in between the tubular End 4 and the tube extension 5 an annular space 6.
  • a locking element 7 is inserted in the annular space 6.
  • the locking element 7 has one to the tubular End 4 concentric ring part 8.
  • Two locking cams 9 projecting radially outwards, each through a slot 10 of the tube extension 5 protrude and a locking projection 11 formed on the wall part 1 reach under.
  • the suction nozzle 3 on the vacuum cleaner housing held in the suction opening 2.
  • Axially above everyone Locking cam 9 is in each case by a corresponding Opening 12 in the wall of the suction nozzle 3 protruding outwards
  • Release button 13 is provided on the ring part 8.
  • the Release buttons 13 exerted a corresponding pressure.
  • the ring part 8 is correspondingly radially inward deformed so that the locking lugs 9 out of engagement with the locking projection 11 come and the suction nozzle 3 from the suction opening 2 can be pulled out.
  • the locking element 7 On the locking element 7 is also a tubular Extension 14 provided.
  • the inside diameter of this extension 14 corresponds to the outer diameter of the tubular End 4 of the suction nozzle 3 so that the locking element 7th with its extension 14 to the tubular end 4 of the Suction nozzle 3 can be pushed.
  • locking lugs 15 are provided, which in corresponding adapted locking recesses 16 of the tubular end 4 engage.
  • the locking lugs 15 and the locking recesses 16 are so shaped that in the sliding direction of the locking element 7 a latching takes place in the direction of the slide opposite direction is no longer solvable.
  • a collar 18 is formed which is inclined radially outwards, which in turn has a sealing lip at its free end 19 is provided.
  • the outer diameter of the sealing lip 19 is in the state not plugged into the suction opening 2 Intake 3 dimensioned slightly larger than the inner diameter the suction opening 2 in the area in which the Sealing lip 19 in the state coupled to the suction opening 2 the suction nozzle 3 is located. This ensures that the sealing lip 19 when coupling the suction nozzle 3 the suction opening 2 under a certain state of tension creates the wall 20 of the suction opening 2. This is a perfect one Sealing the coupling point of the suction nozzle 3 to the Suction opening 2 guaranteed.
  • the quality of the sealing point depends no longer of any length tolerances of the interlocked Parts off. Also have exerted on the suction nozzle 3 Tensile forces no longer influence the sealing effect. Such Influences can only lead to an axial displacement of the Line of contact of the sealing lip 19 with the wall 20 of the suction opening 2 lead.
