Definitions

  • the invention relates to a vacuum cleaner housing with at least one bearing pin projecting on a wall part of the vacuum cleaner housing and having at least one radially directed undercut.
  • Such a vacuum cleaner housing is known from DE-A-42 21 817.
  • a turntable provided with a guide wheel is arranged in a corresponding housing recess.
  • the turntable is rotatably mounted on a bearing journal formed on the housing wall within the housing recess, the turntable being locked in undercuts provided on the bearing journal. Due to the position of the bearing pin within the housing recess, there are considerable problems in the production of the undercuts required on the bearing pin, since, due to the limited space within the housing recess, only little space is available for the side shifters required on the injection mold, so that these are difficult to attach. In addition, the injection mold is more susceptible to failure because of the complicated structure caused by the side shifters.
  • the invention has for its object to provide a vacuum cleaner housing of the type described above so that it can be manufactured with a simpler tool.
  • the bearing pin is formed as a separate component and can be fastened to the wall part of the vacuum cleaner housing by means of a latching connection. Since the bearing journal is designed as a separate part, there is a part that is easy to remove from the production point of view with regard to the vacuum cleaner housing. The tool can therefore be essential be made easier.
  • the separate production of the journal also poses no problems, since there is no longer any spatial disability.
  • the separate production also has the advantage that a different material that better corresponds to the function of the journal can be selected for the journal.
  • a forcefully highly resilient locking connection results from the fact that it consists of parts that engage behind one another in the manner of a bayonet catch. When assembling the impeller, these parts are brought into engagement with one another by rotating them against one another.
  • an advantageous constructive embodiment results from the fact that a radially directed bearing surface is provided on the fastening side of the bearing journal, with which the bearing journal lies against the relevant wall part of the vacuum cleaner housing and that at least one wall wall of the wall part is opposite the Support surface spaced radial projection is provided, which can be passed through a corresponding push-through opening in the wall part of the vacuum cleaner housing and engages behind the wall part by rotating the bearing pin, the bearing pin being locked in this position.
  • a loosening of the bearing journal is prevented in that a latching and counter-latching element are provided on the wall part of the vacuum cleaner housing and on the bearing surface of the bearing journal, which are locked together in the mounting position of the bearing journal on the wall part of the vacuum cleaner housing.
  • the bearing pin 2 has on its fastening side a radially projecting bearing surface 4 with respect to its longitudinal axis 3, with which it bears against the wall part 1 in the state attached to the vacuum cleaner housing.
  • a round axial projection 5 is formed, on which in turn two opposite radial projections 6 are formed, which are axially spaced from the bearing surface 4 by the wall thickness of the wall part 1.
  • a push-through opening 7 is provided, the circumferential contour of which corresponds to the circumferential contours formed by the axial projection 5 and the radial projections 6 formed thereon.
  • This circumferential contour has an elliptical shape. It could also correspond entirely to an ellipse.
  • a latching recess 8 is formed thereon.
  • This locking recess is arranged at a position spatially offset by 90 ° with respect to the connecting axis 9 of the two radial projections 6.
  • a latching tongue 11 is arranged in a wall opening 10, at the free end of which one from the Level of the wall part 1 projecting locking lug 12 is located.
  • the locking lug 12 lies on the central axis 13 of the radial bulges 14 of the push-through opening 7 corresponding to the radial projections 6.
  • the bearing journal 2 which is designed as a separate component, is inserted through the push-through opening 7 of the wall part 1 when it is attached to the wall part 1 with the radial projections 6.
  • the radial projections 6 coincide with the radial bulges 14 of the push-through opening 7.
  • the bearing journal 2 is then rotated through 90 °.
  • the radial projections 6 engage behind the wall part 1 in the region 15 lying between the two radial bulges 14.
  • FIG. 3 the position of the radial projections 6 in this position of the bearing journal 2 is shown in broken lines. The bearing journal 2 is thus fixed in this position on the wall part 1 in the axial direction.
  • the locking recess 8 When the bearing pin 2 is rotated by 90 °, the locking recess 8 also reaches the locking lug 12 of the locking tongue 11. As a result of the elasticity of the locking tongue 11, the locking lug 12 snaps into the locking recess so that the bearing pin 2 can no longer be rotated.
  • the bearing journal 2 is thus fixed on the wall part 1. It is advantageous to provide two opposing locking recesses 8 instead of a locking recess 8, since the bearing journal 2 can then be rotated in any direction during assembly on the wall part 1 in order to bring about the locking with the locking tongue 12.
