Definitions

  • the present invention relates to a filter device for a vacuum cleaner with a filter bag and an attached holding plate provided with an inflow opening and with a closure plate which is displaceable in its longitudinal direction, which can be brought into a position which releases and covers the inflow opening of the holding plate and with its longitudinal edge regions in guide elements Holding 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 lie congruently with one another, so that the connection of the filter bag interior with the nozzle of the Vacuum cleaner can be made.
  • the closure plate is moved so that the inflow opening of the holding plate is closed.
  • a filter device known from DE-GM 91 01 700 are the guide elements of the holding plate guide tabs, which are formed by arcuate incisions.
  • the guide tabs can be deformed accordingly for the insertion of the closure plate.
  • the present invention has for its object to provide a filter device of the type mentioned with improved guidance for the closure plate.
  • the filter device with the closed bag should be simple and easy to remove from the guide frame of the vacuum cleaner.
  • the object is achieved in that the guide elements extend essentially over the length of the holding plate, and in that the holding plate is formed from at least two layers at least in the edge regions.
  • the closure plate is now guided approximately over the entire length of the holding plate. This effectively prevents hiding and canting. If the edge regions are double-layered, strips that fire the filter device may be omitted.
  • the length of the guide elements corresponds essentially to that Length of the holding plate and is therefore much cheaper compared to the guide tabs according to the prior art.
  • the mutually facing edge regions of the position of the holding plate facing away from the filter bag are formed as guide strips which are formed by deformation and overlap the edge regions of the closure plate.
  • the restoring forces formed by the deformation cause the closure plate to be pressed against the holding plate with a certain pressing force, so that the closure is extremely tight.
  • the guide strips are expediently shaped by embossing the corresponding material parts in such a way that they are offset relative to the plane formed from the assigned layers to the side facing away from the filter bag. The embossing or shaping takes place in such a way that the distance of the guide strips from the assigned surface of the holding plate corresponds to the thickness of the closure plate or approximately corresponds.
  • the holding plate is formed in two layers and that the closure plate is slidably guided between the two layers of the holding plate.
  • the closure plate cannot be pulled out of the guides, since it is covered on both sides by the two layers of the holding plate.
  • that of the holding plate and the closure plate formed unit are made from a one-piece blank if the connecting area between the layers forming the holding plate and the closure plate consists of several lamellae.
  • This embodiment also advantageously offers the possibility that the filter bag can be glued to both sides of the holding plate.
  • a particularly simple embodiment results if the opposing longitudinal edge edge regions of the holding plate are connected to one another by adhesive to form the guide elements for the closure plate.
  • the holding plate has at least on one side two guide tongues assigned to the longitudinal edges of the closure plate, the mutually facing, parallel and spaced end edges of which form guide surfaces for the closure plate. Since the cuts are made extremely precisely in the course of the manufacture of the holding and closing plate, the closing plate is guided exactly.
  • the closure plate is usually movably connected to the holding plate. The guide tongues are then on the side facing away from the connection area.
  • the guide surfaces of the guide tongues are slightly offset towards the center towards the outer fold edges of the guide strips.
  • the closure plate can be moved particularly easily since the edges of the closure plate are only moved into the region of the guide strips which are parallel to the plane of the Sealing plate lie, or in the second embodiment in the parallel areas of the two layers.
  • the holding plate of the filter device is usually inserted into a guide frame of the vacuum cleaner. It is now desirable that the inflow opening of the holding plate be closed before being removed from the guide frame. So that even in such a position of the filter device, the guidance of the closure plate is ensured, it is provided in a further embodiment that the holding plate is provided on the two longitudinal edges with at least one latching recess, engage in the latching cams of the guide frame when the closure plate is inserted therein. In a particularly advantageous manner, these locking recesses are located at the end of the closure plate, which is assigned to the connection area between the holding plate and the closure plate.
  • the strip-shaped edge regions of the holding plate can move towards one another, so that the filter device can be easily pulled out of the guide frame. Due to the tight fit before closing, the exact guidance of the closing plate is given.
  • the filter bag 10 of the filter device is only indicated in dash-dotted lines in FIG. 1.
  • the filter bag 10 is fastened to a holding plate 11 in a manner that is not explained in more detail.
  • the holding plate 11 is provided with a central, circular inflow opening 12, which, however, is only partially visible in FIG. 1, since a closure plate closes the inflow opening 12 13 is shown in an intermediate position.
  • the closure plate 13 is also provided with a central and circular opening 14, the inflow opening 12 and the opening 14 being congruent with one another when the filter device is inserted in a vacuum cleaner housing.
  • the closure plate 13 is moved before removal from the vacuum cleaner housing in such a way that the inflow opening 12 of the holding plate 11 is completely closed.
  • the closure plate 13 is movably connected to the holding plate 11.
  • the connection area is formed by a plurality of lamellae 15 running transversely to the longitudinal edges. It can be seen from FIGS. 1 and 2 that the holding plate 11 is formed on the two long sides from two layers 11a, 11b, which are connected to one another by adhesive bonding.
  • the figures also show that the mutually facing edge regions are deformed in the manner of an offset, so that guide strips 16 are formed for the closure plate 13.
  • the surfaces of the guide strips 16 facing the filter bag 10 lie at a distance from one another corresponding to the thickness of the closure plate 13.
  • the material layers 11a, 11b facing away from the filter bag 10 are also provided with two guide tongues 17, 18, which are assigned to a transverse edge.
  • these guide tongues 17, 18 lie on the side opposite the connecting region of the holding plate 11 to the closure plate 13. If the holding plate 11 is not connected to the closure plate 13, they lie in the region of the front edge when the movement of the closure plate 13 to close the inflow opening 12 is taken as a basis.
  • FIG. 3 shows the design of the guide tongue 18.
  • the guide tongue 17 is a mirror image of this. So that an exact transition from the Guide strips 16 to the guide tongues 17, 18 are provided in the transition area punched 19, 20.
  • the holding plate 11 On the transverse edge opposite the guide tongues 17, 18, the holding plate 11 is provided on the outer longitudinal sides with two latching recesses 21, 22. These locking recesses 21, 22 engage in locking lugs of the guide frame when the holding plate 11 is inserted therein.
  • the holding plate 11 is also provided with insertion bevels 23, 24.
  • latching tongues, not shown, of the holding frame of the vacuum cleaner can spring back when the holding plate 11 is pulled out of the holding frame. As a result, the filter device can be removed from the holding frame with little effort. From Figure 1 it also follows that the guide strips extend approximately over the entire length or height of the holding plate 11. This length is only reduced by the height of the guide tongues 17, 18.
  • Figures 1 and 5 show that the closure plate 13 is provided with two finger holes 25 which are arranged in the edge region running transversely to the guide strips 16. This edge area is facing away from the slats 15. When moving the closure plate 13 you can then engage in these finger holes 25.
  • two elongated holes 26 are provided in the holding plate 13 facing the filter bag 10, the central longitudinal axes of which are aligned with the center points of the circular grip holes 25.
  • the holding plate 13 projects outwards relative to the guide strips.
  • the diameter of the grip holes 25 is approximately the same as the width of the elongated holes 26 match.
  • the length of the elongated holes 26 is selected so that in the open position of the closure plate 13, the finger holes 25 lie on the sides of the elongated holes 26 facing the inflow opening 12. In the closed position of the closure plate 13, the finger holes 25 are located in the opposite region of the elongated holes 26.
  • moving the closure plate 13 one can reach through the elongated holes with the fingers. This ensures that when the inflow opening 12 is closed, when the filter bag 10 is removed from the guide frame of the vacuum cleaner, the closure plate 13 is not peeled out of the guide strips 16.
  • FIGS. 6 to 8 show a further exemplary embodiment of the unit formed from the holding plate 11 and the closure plate 13. Identical parts are also identified by the same reference numerals as in the exemplary embodiment according to FIGS. 1 to 5. From Figure 6 it follows that the holding plate 11 and the closure plate 13 are made from a one-piece blank. FIG. 6 also shows that the holding plate 11 consists of two adjacent individual plates 11c, 11d arranged in mirror image to one another. To produce the unit shown in FIG. 7, the individual plates 11c, 11d are folded around the mirror axis 27. Before that, however, the closure plate 13 was folded around the uppermost lamella 15 facing away from the inflow openings 12, so that it lies between the two individual plates 11c, 11d.
  • a recess 28 is provided on both sides of the mirror axis 27 and extends approximately over the entire width of the individual plates 11c, 11d.
  • the holding plate 11 is not only double-layered in the longitudinal edge areas, but over the entire surface. This makes it impossible that the closure plate 13 can be pulled out of the plane of the holding plate 11.
  • the longitudinal edge edge regions of the individual plates 11c, 11d are glued together to form the holding plate 11.
  • the application of adhesive is not shown in FIG.
  • the embodiment according to FIGS. 6 to 8 is also provided with the latching recesses 21, 22 and the insertion bevels 23, 24.
  • FIG. 9 shows a further exemplary embodiment of the present invention.
  • the holding plate 11 and the closure plate 13 are made from a one-piece blank, which is shown in FIG. The difference is that adhesive flaps 29, 30 are provided on both end faces of the individual plate 11d.
  • the adhesive tabs 29, 30 are part of the blank, which in turn is in one piece. After the blank has been folded, these adhesive flaps 29, 30 are folded along the folding lines 31, 32 onto the outside of the individual plate 11c of the holding plate 11 and glued to the adjacent material layers, so that the stability of the holding plate 11 is ensured.
  • the embodiment shown in FIG. 9 is cheaper in terms of production technology, since the embossing process is omitted compared to the embodiments according to FIGS. 1 to 5. In addition, it is prevented in machine production that the closure plate 13 is also glued in an undesired manner.
  • the lamellae extend 15 only over the central region of the individual plate 11c or the closure plate 13. Since they do not protrude into the edge region, there is a favorable spring effect between the individual plates 11c and 11d of the holding plate 11. Since the individual plates 11c, 11d of the holding plate 11 are made in one piece are manufactured, a higher load capacity is achieved, so that the adhesive connection is relieved.
  • the slats 15 can only extend over the central area.
