Definitions

  • the invention relates to a filter device for a vacuum cleaner with a filter bag and a holding plate attached thereto and provided with an inflow opening and with a longitudinally displaceable closure plate which in one Inflow opening of the holding plate releasing and covering position can be brought and is guided with its longitudinal edge areas in guide elements of the holding plate, the guide elements extending essentially over the length of the holding plate, the holding plate consists of two individual plates and between the two layers of the holding plate the closure plate is guided.
  • the closure plate is usually provided with an opening which corresponds to the inflow opening of the holding plate, so that in the corresponding position of the closure plate, the openings of the holding plate and the closure plate are congruent with each other, whereby the Connection of the filter bag interior made with the nozzle of the vacuum cleaner can be.
  • the Closure plate moved so that the inflow opening of the holding plate is closed is.
  • a filter device in which the holding plate consists of two layers.
  • the closure plate is arranged between these two layers.
  • the holding plate is not connected to the closing plate. So that the closure plate cannot be pulled out of the holding plate, are the two End positions limited by stops of the closure plate and the holding plate.
  • the holding plate is made from one piece.
  • a connection of the longitudinal edge areas of the two layers of the holding plate is in the different versions not known to be known.
  • the closure plate is within the double layer Holding plate guided separately and positively. Nevertheless, it cannot be ruled out that the guidance is inaccurate, so that there is a tilting and tilting can come.
  • the object is achieved in that the opposite longitudinal edge areas the two layers of the holding plate to form the guide elements for the closure plate are connected to each other by adhesive, and that the connection area between the holding plate and the closure plate by a plurality of incisions formed slats extending transversely to the end edges is formed, and that these Slats only extend over the central area of the holding plate.
  • the closure plate is now approximately over the entire length of the holding plate guided. This means that hiding and canting will still be effective prevents if the adhesive connection of each longitudinal edge area even out there are at least two adhesive dots.
  • the closure plate not only through the two individual plates, but also through the slats.
  • the slats in particular bring about a special side stabilization of the Locking plate.
  • the closure plate is on both sides of the layers of the holding plate covered so that it cannot be pulled out. There is a possibility optionally glue the filter bag on both sides of the holding plate.
  • the holding plate becomes a particularly simple design for forming the guide elements reached for the closure plate.
  • the area of leadership is precisely defined by the two layers of the holding plate lying against one another it happens that the movement of the closure plate is stiff.
  • the holding plate at least on one side two guide tongues assigned to the longitudinal edges of the closure plate has whose mutually facing, parallel and spaced from each other Form the front edges of the guide surfaces for the locking plate. Because the cuts carried out extremely precisely in the course of the manufacture of the holding and closing plate the closure plate is guided exactly. Since the closure plate with the holding plate is movably connected by the slats, the guide tongues are then on the side facing away from the connection area. The closure plate can be move particularly easily since they are only in the area between the two parallel ones Layers is moved.
  • the holding plate of the filter device in a guide frame of the Vacuum cleaner used. It is now desirable that the inlet opening of the Holding plate is closed before removal from the guide frame. Thus, even in such a position of the filter device, the guidance of the closure plate is guaranteed, it is provided in a further embodiment that the Provide the holding plate on the two longitudinal edges with at least one locking recess is to engage in the locking cams of the guide frame when inserted therein is. In a particularly advantageous manner, these locking recesses lie on the End of the holding plate, which is the connection area between the holding plate and is assigned to the closure plate.
  • the filter bag is in a manner not explained on a holding plate 11 attached.
  • the holding plate 11 is in the illustrated embodiment with a centric, circular inflow opening 12 provided.
  • the closure plate 13 is also provided with a central and circular opening 14, the Inflow opening 12 and the opening 14 when used in a vacuum cleaner housing
  • the filter device is congruent. After the filter bag has reached the filling level, before being removed from the vacuum cleaner housing the closure plate 13 moves so that the inflow opening 12 of the holding plate 11 is completely closed.
  • the connection area is across by several the longitudinal edges extending fins 15 are formed.
  • the holding plate 11 and the closure plate 13 formed a unit. From Fig. 1 it follows that the holding plate 11 and the closure plate 13 made from a one-piece blank are. Fig. 1 also shows that the holding plate from two adjacent, mirror image individual plates 11c and 11d arranged to each other. To make the unit shown in FIG. 2, the individual plates 11c, 11d around the mirror axis 27 folded. Previously, however, the closure plate 13 was the in the inflow openings 12 facing away from the top lamella folded so that they between the two individual plates 11c, 11d.
  • FIG. 4 shows a further exemplary embodiment of the present invention. How 1 to 3 is the holding plate 11 and the Closure plate 13 made from a one-piece blank, which is shown in FIG. 4 is. The difference is that on both ends of the single plate 11d adhesive tabs 29, 30 are provided. The adhesive tabs 29, 30 are part of the blank, which in turn is in one piece. After folding the blank these glue tabs 29, 30 along the fold lines 31, 32 to the outside of the Single plate 11c of the holding plate 11 folded and with the adjacent layers of material glued so that the stability of the holding plate 11 is ensured. This will help Mechanical production prevents the closure plate in an undesired manner 13 is glued with. In the embodiments shown in FIGS.
  • the slats 15 extend only over the central region of the single plate 11c or the closure plate 13. Since they do not protrude into the edge area, there is a favorable spring effect between the individual plates 11c and 11d Holding plate 11. Since the individual plates 11c, 11d of the holding plate 11 are made in one piece are, a higher load capacity is achieved, so that the adhesive connection is relieved becomes.
