Definitions

  • the invention relates to a holding plate for a vacuum cleaner filter bag of the type specified in the preamble of claim 1.
  • a holding plate of this type known from DE-OS 2 407 478 consists of two layers which are glued together and which have a hole in the middle and between which there is a tab.
  • the tab is an opening provided with a band or strip which is connected at its end to a layer of the holding plate and folded so that the passage opening remains free in the position of use and the band is stretched by pulling at the other end and thereby the passage opening is blocked .
  • This holding plate is in three parts, consisting of a base plate, a cover plate and a tab. The production of this holding plate is therefore technically complex and therefore expensive.
  • the invention has for its object to provide a holding plate of the type mentioned that is simple and inexpensive to manufacture, easy to use and allows a safe closing of the passage opening.
  • the flap is formed in one piece with the base plate, a thin, easy-to-bend material is selected for this molded part.
  • the cover plate fixed on it is used in a rigid form.
  • the displaceable tab could also be formed in one piece with the cover plate, which would then have to be selected to be thin and easy to bend, the base plate again having to be formed from rigid material.
  • the essential idea of the invention is to give the holding plate in its entirety the necessary rigidity in order to ensure a secure fit in the vacuum cleaner.
  • the tab on the other hand, is designed so soft that in its foldable area it offers little resistance when moving and the deflection loop remains quite flat and only forms a small radius, but the tab still has sufficient inherent strength.
  • the tab Due to the one-piece design of the tab with the cover plate or with the base plate, there is no danger when closing that the tab can be removed detachably alone. In the shut-off position, the tab keeps the passage opening of the holding plate optimally closed, so that no dust can escape when the filled filter bag is removed and transported.
  • the proposed two-part embodiment of the holding plate ensures that it can be manufactured inexpensively.
  • a material saving is achieved in that only those parts which give the holding plate its strength consist of thick or stiff material.
  • This will also achieved that the holding plate can be made considerably thinner than would be possible if the same materials were used for all components.
  • connection points or mechanical connections such as Proven riveting.
  • welding is preferable because it is easier to carry out.
  • the molded parts are preferably connected exclusively in the region of the side edges of the holding plate. In this case, the connection of the molded parts also acts as a guide for the tab. If the connection points are approximately diagonally opposite one another, two connection points are sufficient to ensure that the base plate and the cover plate are held securely and to give the tab sufficient guidance.
  • the embodiment according to claim 3 is particularly favorable since the displacement of the tab that is inseparably connected to the base plate on one side with a foldable area is particularly easy to implement.
  • the tab is turned through 180 °.
  • the folding area can be folded by a particularly small bending radius due to the flexible material from which the flap is made. This prevents the cover plate from lifting off the base plate.
  • the production of the tab together with the cover plate as a one-piece molded part is particularly cost-effective.
  • Particularly favorable slip shadows are obtained according to claim 5 by coating the surface.
  • this surface coating can be accompanied by the printing of symbols or names, which reduces additional costs.
  • a coating results in a particularly smooth surface, which also improves the sealing effect of the tab. This is particularly the case with Dust allergies are important wherever any leakage of dust from the filter bag must be avoided.
  • the molded part has a smaller width in the foldable area than in the area of the flap.
  • the width of the tab is determined by the diameter of the passage opening to be covered.
  • the width of the molded part can be reduced in the foldable area. This saves material.
  • the holding plate made of cardboard or cardboard. Since these materials are particularly inexpensive, they are preferable in the case of disposable filter bags. They also rot easily.
  • the flap is preferably made of cardboard or strong paper.
  • Another alternative is the use of composite materials, the mechanical properties of which can be tailored for this application.
  • a holding plate H for a vacuum cleaner filter bag (not shown) according to FIG. 1 has the task of closing access to the suction chamber of the vacuum cleaner and only opening one passage to the interior of the filter bag.
  • the full filter bag should be closed during removal and transport.
  • the holding plate H consists of a base plate 1, a cover plate 2 and a tab 3.
  • the filter bag is connected to either the base plate 1 or the cover plate 2.
  • In the base plate 1 there is a passage opening 1a for receiving a suction nozzle of the vacuum cleaner.
  • a seal is attached to this opening, which separates the suction port of the vacuum cleaner from the space outside the filter bag in an airtight manner. This seal is not shown in Figure 1 to increase clarity.
  • the base plate 1 is glued to the cover plate 2 at points K, welded or inseparably connected by mechanical elements. Alternatively, the connection could take place along the entire edges K 1 or at one or a few points along both edges K 1 .
  • the cover plate 2 also has a passage opening 2a, which is aligned with the passage opening 1a of the base plate 1. Between the base plate 1 and the cover plate 2 there is a slidably held tab 3. In order to increase the slidability of the tab 3, the surface O 1 or O 2 of at least one molded part Z 1 , Z 2 is smoothed or coated with a lubricious layer.
  • the tab 3 has an opening 3a which, in the position of use of the tab 3 shown in FIG. 1, opens the passage opening 1a of the base plate 1.
  • the cover plate 2 is made in one piece with the tab 3.
  • This molded part Z 2 has a foldable area 4, which is shaped to improve its bending properties with cuts 5 perpendicular to the direction of displacement of the tab 3 into slats 6.
  • the slats 6 run like a blind.
  • the width of the molded part Z 2 in the area of the fins 6 is reduced in order to improve its elasticity in bending.
  • FIG. 3 shows a folded blank of the molded parts Z 1 and Z 2 , for example made of cardboard, film or plastic, from which the holding plate H according to FIGS. 1 and 2 can be produced.
  • the molded part Z 1 consists of a rigid material and forms the base plate 1.
  • the one-piece molded part Z 2 forms the cover plate 2 together with the tab 3 and consists of a softer, flexible material than the molded part Z 1 .
  • the two molded parts Z 1 and Z 2 are placed one on top of the other in such a way that the adhesive points K shown overlap.
  • the tab 3 is folded in the direction of the cover plate 2, so that the molded part Z 2 is deflected in the region 4 by 180 °.
  • the cover plate 2 is glued to the base plate 1 at the points K, welded or otherwise mechanically inseparably connected.
