Definitions

  • the invention relates to a connector of a filter bag for vacuum cleaners, with a fixed, essentially plate-shaped Basic body, the inner one facing the bag Material layer and an outer material layer facing away from the bag, has these layers of material, in particular of cardboard material, which are arranged one above the other and on both sides one between their existing, open end guide slot are connected to one another in which a protruding from the base body Locking slide is guided, the base body a connection opening formed by aligned perforations in the material layers and the slide valve has a through opening has and the slide valve from a connection opening releasing open position, in its through opening is aligned with the connection opening, in a connection opening closing position is movable and the base body on its outside facing away from the bag forms a contact surface surrounding the connection opening, the one in the state in the vacuum cleaner Sealing body of the vacuum cleaner rests.
  • Vacuum cleaners are used to collect the accumulated Dusty filter bags - including larger filter bags or to understand - used. Doing so generates a suction flow by means of a vacuum cleaner fan, which the dust into a suction channel, suction hose or the like pulls and from there through the dust inlet opening in the concerned Filter bag promotes. The one in the sucked air dust contained is retained by the filter bag wall, during the dust-free air flow the filter bag wall penetrated and then blown into the environment. If the filter bag is full, it is removed and can be thrown away become.
  • a exclusion piece of the type mentioned is from the EP-A-0 623 305 known. This is done Fix the filter bag on the vacuum cleaner using the attached to the filter bag in the area of its inlet opening Connector that is attached so that the from its base body formed connection opening with the inlet opening of the actual filter bag, so that the Dust air can be introduced. With the help of the slide can then the mentioned connection opening and thus also the inlet opening of the filter bag is closed, when the filter bag is removed from the vacuum cleaner. On this way no dust can be removed from the removed filter bag escape into the environment.
  • the guide slot of the connector receiving the slide is however at its the direction of movement of the Slider corresponding ends open because of the slider protrudes from the base here so that it Hand can be taken. Although it is a very flat, essentially the material thickness of the slide gate corresponding guide slot. Nevertheless, dust particles, especially if the dust is fine, get out through the open guide slot ends and contaminate the filter bag receiving area of the vacuum cleaner.
  • the present invention is therefore based on the object to create a connector of the type mentioned at which improves the tightness against dust leakage. This should be achieved with the simplest possible means, what is particularly important with regard to this, that this is a mass article.
  • connection opening of a starting from the inner material layer bearing ring protruding in or through the perforation of the outer material layer is arranged, which forms the contact surface or a holds the sealing surface forming part in position, whereby the base body with the contact ring and / or the locking slide are so flexible that the locking slide over the bearing ring is movable away into its closed position.
  • This contact ring or the sealing part held by it in position seals on the one hand against the vacuum cleaner side Sealing body and the other around the circumference Guide slot of the slide gate, so that also on the Guide slot no dust can get into the vacuum cleaner.
  • the bearing ring is expediently in one piece with the inner ring Material layer of the base body connected by the perforation of the inner material layer a smaller diameter than the perforation the outer layer of material, so that a radial inside over the perforated edge of the perforation of the outer material layer protruding ring area of the inner material layer is formed becomes that in or through the perforation of the outer material layer projecting bearing ring is shaped.
  • the ring can forming ring area of the inner material layer at the edge of the hole the outer layer of material. In this way can in the manufacture of the hole edge of the outer layer of material so to speak as a shaping part when pressing the bearing ring be used.
  • the sealing part can be a perforated sealing membrane which between the two material layers of the base body is.
  • the filter bag is made of air-permeable filter material (Paper, fleece, etc.) and is placed in a dust-extracting device, so used in a vacuum cleaner.
  • the connector serves 1 for connecting the filter bag with the vacuum cleaner.
  • the connector 1 is essentially one of the filter bag fixed, essentially plate-like shape having base body 5 and a locking slide mounted on this 6 formed.
  • the outline of the base body 5 can be shaped like a rectangle or in another way, so that one receives an adaptation to the respective device type of the vacuum cleaner.
  • the base body 5 has two cardboard-like ones arranged one above the other rigid material layers 7, 8, which are regularly made of cardboard material consist.
  • One of the material layers, the material layer 7 (hereinafter referred to as the inner material layer) is the filter bag front wall 2 facing and glued to this while the other Material layer, the outer material layer 8, the filter bag is facing away and the outside of the connector facing away from the bag 1 forms.
  • the base body 5 also contains the already Mentioned port 4 with which the connector 1 plugged onto a connecting piece on the vacuum cleaner can be.
  • connection opening 4 is through a corresponding Perforation of the two layers of material 7, 8 produced, see above that on the inner layer of material 7 a perforation 9 and on the outer Material layer 8 a perforation aligned with the perforation 9 10 is present.
  • the closure slide 6 is between the two base material layers 7, 8 guided in its longitudinal direction L. and can be made of film-like thin, flexible material, the slide 6 in its longitudinal direction L also composed of several areas of different strength can be, but not in the present context interested.
  • Form for storage of the slide 6 the two layers of material 7, 8 have a guide slot between them 11.
  • the material layers 7, 8 are on both sides of the guide slot 11, d. H. on both sides of the guided in this Locking slide 6, in the areas 12, 13 firmly together connected, which is done regularly by gluing. Between the two material layers 7, 8 are not connected to the two areas 12, 13, so that the slide 6 is added and in Longitudinal direction L can be moved.
  • the slide valve 6 contains one of the connection opening 4 of the Main body 5 assigned through opening 14.
  • the slide 6 In its initial position, which he when inserting the connector 1 in occupies the vacuum cleaner, there is the slide 6 in its open position (Figure 1), in the through opening 14 at the location of the connection opening 4 of the base body is arranged so that this and thus also the inlet opening 3 of the filter bag is free. From this open position can the slide 6 in a closed position ( Figure 2) are moved in which it closes the connection opening 4. In the exemplary embodiment, this movement is carried out by pulling of the slide 6 in the longitudinal direction L.
  • the slide valve 6 has in its in the embodiment direction of movement coinciding with the longitudinal direction L. on the one hand the through opening 14 has a closure area 15 and on the other hand the through opening 14 one outside of the base body 5 arranged handle 16, which with the Hand can be taken. You pull the handle in Figure 1 16 to the left, the closure area 15 comes into place the connection opening 4 of the base body and closes it.
  • the slide 6 can, but not necessarily, also protrude with its closure region 15 from the base body 5, and on the side of the body opposite the handle 16.
  • 3 and 4 are in the cross-sectional illustration from the slide 6 only the two on both sides of the through opening 14 horizontal, web-like locking slide areas 17, 18 visible.
  • the two basic material layers are 7, 8 wider than the slide 6 and on both sides of this on the side areas 12, 13 over the base body length glued together.
  • the area leading the slide can at least one of the material layers by means of the slide slide on both sides attached embossing lines 21, 22 somewhat offset, d. H. be somewhat distant from the other material layer.
  • the Sliding game for the slide gate could be reach in other ways. This is in the present context but of no further interest.
  • the guide slot 11 is open at both ends 23, 24, d. H. the two layers of material 7, 8 are not on top of each other here glued so that the slide 6 can emerge. Possibly, when the slide gate with its handle opposite end should not protrude from the main body, you could also use the guide slot at that end close. In any case, the guide slot is open at least at the end facing the handle 16.
  • the Vacuum cleaner for which the filter bag shown is intended has a fixed sealing body, one on the outside of the base body 5 of the connector 1 around the connection opening 4 circumferential contact surface is assigned, which in inserted in the vacuum cleaner state on the facing Sealing surface 25 of the sealing body arranged on the vacuum cleaner rests, so that here one around the connection opening 4 Ring seal is formed.
