Definitions

  • the invention first relates to a dust filter bag for a vacuum cleaner, with a holding plate, preferably made of cardboard paper material, layered one above the other, with which a dust bag is, for example, adhesively bonded, which holding plate has a sealable opening for a suction pipe of a vacuum cleaner, the opening having a separate closure element is closable, which can be moved from an open position into a closed position, the closure element located below an uppermost layer of the holding plate further having an edge which can be moved in the open position in abutment with a stop.
  • a dust filter bag provided with such a holding plate is known, for example, from WO 95/15108.
  • a holding plate is specified which has a closure element which can be displaced from an open position into a closed position between two layers.
  • the holding plate is constructed in four layers, the closure element being arranged between a first, the uppermost layer and a third layer, and a stop being formed between these two layers, ie in the plane of the closure element, against which the closure element comes into contact in the open position ,
  • the edge of the closure element which corresponds to the stop extends here almost — viewed transversely to the direction of displacement of the closure element — the entire width of the closure element, which has a spade-shaped design.
  • the closure element essentially consists of a closure plate closing the opening of the holding plate and a spade handle arranged thereon, the spade handle being positioned on the side of the closure plate opposite the opening. In the transition area from the closure plate to the spade handle, the edge that is movable against the stop is formed.
  • a dust filter bag of this type is also known from US-A-5 468 272.
  • a technical problem of the invention is seen in specifying a dust filter bag for a vacuum cleaner with a holding plate, preferably made of a cardboard paper material, which is distinguished in terms of improved functional reliability of the displaceable closure element.
  • the holding plate comprises a layer on which the stop is arranged, so that the stop and the peripheral edge are exposed in the open position in a free cut area of the top layer ,
  • the stop area is disclosed and is therefore accessible.
  • the user can remove any soiling from the area of the stop, which soiling could otherwise impair the function of the closure element.
  • this configuration according to the invention makes it possible to first connect the closure element to the holding plate in the region of the stop during the production of the holding plate and to detach it from the holding plate only in a last working step.
  • a knife-like tool can cut through the closure element layer in the area of the stop to be formed, for example in the area of the cutout of the top layer. Only then is the closure element released for displacement.
  • This avoids all production problems associated with a part that is not stable. This prevents, for example, interlocking of layers that have already been punched out from one another, since the attached closure element cannot protrude from the plane in which it is attached.
  • it is also conceivable here in the area of the stop to connect the closure element to the remaining holding plate via a perforation. This connection is only broken up by the user when the closure element is actuated for the first time.
  • there is the advantage that the closure element is firmly attached to the holding plate over the entire production process.
  • the holding plate in four layers, the closure element being slidably arranged between an uppermost, the first layer and a third layer.
  • the second layer formed here is composed of the closure element and a fixed layer which is firmly connected to the other layers and forms the guide and the stop of the closure element.
  • the closure element is laterally viewed from this second position in the direction of displacement.
  • the stop area is free to eliminate any malfunctions that could affect a displacement of the closure element.
  • a holding plate made of a cardboard-paper material with the same cardboard quality compared to the known prior art is significantly stiffer in terms of bending and twisting. This can be used, for example, to increase the functional reliability of the entire closure system with unchanged cardboard quality and unchanged locking mechanism, in order to increase quality, further with unchanged cardboard quality to simplify the mechanics even while tolerating increased forces impressed into the holding plate or with unchanged mechanics and unchanged Functional reliability to reduce the cardboard quality, both with a view to reducing costs.
  • the connection of the closure element to the position of the holding plate assigned to this element during production has the further advantage that the process speed in the manufacture of the holding plate can be increased.
  • the invention further relates to a dust filter bag for a vacuum cleaner of the type mentioned, in which the closed position is further limited by a stop.
  • This configuration in particular the Stop-limited locking position is known from WO 95/15108.
  • the stop in the direction of displacement of the closure slide when viewed in the closure position, is formed in front of the opening.
  • the stop limitation of the closed position viewed in the direction of displacement — is formed behind the holding plate opening. Since this area always comes into contact with dust and / or dirt particles due to its function, such particles can accumulate here over time, which can lead to impairment of the limit stop.
  • the closure element may no longer be completely displaceable into the closed position, so that after the dust filter bag has been removed from the vacuum cleaner, the opening of the bag may at least partially be open. For hygienic reasons, this is not desirable.
  • the top layer in the area of the stop has a window-like opening. This window-like opening can be formed in the form of an annular punched-out portion of the uppermost layer, both the stop for defining the open position and the stop for the closed position being able to be provided with a window-like opening.
  • an intermediate stop is formed between a front and a rear end of the locking slide.
  • this intermediate stop is formed from solid cardboard strips of the layer containing the closure element.
  • the intermediate stop is formed from two cardboard strips lying opposite one another in the plane, which extend inwards from the longitudinal sides of the second layer, which are already referred to as "rails", ie in the direction of the closure slide. The slide is slidable between these opposing cardboard strips.
  • the intermediate stop lies in the direction of displacement of the locking slide within the diameter of the opening.
  • the longitudinal edges of the holding plate in the area of the position receiving the closure element have a constant width over the entire length of the holding plate, in particular in the area of the stop and in the area of the holding plate opening, there is the effect that the Cardboard strips forming the intermediate stop would protrude in an extension in the direction of displacement into the area of the holding plate opening.
  • the closure slide on the intermediate stop both in the open position and in the Lock position is present.
  • the intermediate stop is formed between a front and the rear end of the locking slide, for which purpose the locking slide in the region receiving the intermediate stop is, for example, H-shaped and the intermediate stop engages in the waist of the H plan.
  • a rear H-web of the locking slide occurs rearward against the intermediate stop in the closed position and a front H-web is moved against the front in an open position against the intermediate stop. Due to this configuration, a preferred window-like opening of the uppermost layer is only necessary in the area of the intermediate stop to expose both the opening and the closing stop.
  • the closure plate closing the holding plate opening is - viewed in the direction of displacement - positioned in front of the front H-web forming the counter-stop for the open position.
  • a stop edge of the intermediate stop encloses an acute angle with the direction of displacement.
  • the connection to the layer is preferably made in the open position of the closure element, the connection being severed through the window-like opening of the uppermost layer.
  • a separation is preferred here, which is carried out by means of two cuts at angles of 45 ° and 315 ° (based on the longitudinal extent of the holding plate in the direction of the holding plate opening) in the region of the cardboard strips forming the intermediate stop.
  • the web is severed in such a way that a part of the web forms the intermediate stop and part forms a movable stop associated with the locking slide.
  • the above-mentioned front H-web of the closure slide, which defines the open position, is thus formed in the course of severing the connection of the slide to the cardboard layer, so that the stop associated with the slide in a preferred embodiment corresponds to the stop edge of the intermediate stop and also to the direction of displacement has an edge that encloses an acute angle.
  • three stop points are formed.
  • a stop is formed at the end of the slide, which only comes into effect in the open position.
  • This stop is the third stop point to the two stop points of the intermediate stop and is preferably located on the end side of the holding plate opposite the holding plate opening. Against this attack the Lock slide only in an open position in the system.
  • a connection of the slide to the holding plate layer can be provided for fixing the position of the closure slide during the production process of the holding plate, which connection can be severed by a window-like opening of the uppermost layer provided in this area.
  • the end stop is preferably designed like a web here, the connection being severed in such a way that part of the web forms the end stop on the plate side and part forms a movable stop associated with the locking slide.
  • the cut is preferably made at an angle of 90 ° (based on the longitudinal extent of the holding plate in the direction of the holding plate opening). Together with the two oblique cuts of the intermediate stop, these three cuts together, each extrapolated, result in the shape of a blunted arrowhead.
  • the third stop acts as an end stop, which positions the slide in relation to the long holding plate side in its starting position. It is also provided that the slide valve has a slide handle which is exposed in a separate opening and has a form-fitting recess for a lock actuating element.
  • a vacuum cleaner-side closure actuating element which causes the closure slide to be displaced into the open or closed position when the suction housing is closed or opened.
  • designs are known in which an approximately 2 cm 2 piece of cardboard is glued to the slide handle, which is accessible through a separate opening in the holding plate.
  • the slide handle is provided with a form-fitting recess, which ensures that a safe actuation of the closure by a closure actuating element is not dependent on the quality of the bonding of various cardboard layers (slide handle cardboard piece) averaged over a relatively small area. Furthermore, this ensures that the friction of the slide is not directly increased by the normal force impressed on the holding plate by the locking mechanism.
  • the form-fitting recess is preferably designed as a slot. The closure actuating element engages in this slot by appropriate means, it being further preferred that the slot is a through opening.
  • the means of the closure actuating element engaging in the slot thus acts only as a push or pull on the closure slide, the spring force being derived through the slot upon the spring-loaded configuration of the closure actuation element onto the large-area layer arranged below the closure slide.
  • the function of the closure slide is thus not impaired, for example by an increase in the frictional force.
  • the slot extend transversely to the direction of displacement with a length that corresponds approximately to the width of the separate opening.
  • the separate opening is preferably a window-like opening in the area of the top layer formed, the length of which corresponds at least to the displacement of the slide.
  • the width of this window-like opening corresponds to approximately half of the holding plate opening diameter.
  • the slot of the slide handle extends almost over the entire width of the separate opening.
  • the slot width corresponds to approximately a quarter of the length of the slot.
  • a dust filter bag 1 which is composed essentially of a holding plate 2, preferably made of a cardboard paper material, and a dust bag 3, for example adhesive-bonded, preferably made of paper, on the underside of this holding plate 2.
  • the holding plate 2 is composed of four layers of cardboard-paper material which are stacked one on top of the other. These layers 4 to 7 are glued together. The holding plate 2 thus formed is supported in the inserted state of the dust filter bag 1 in a vacuum cleaner on corresponding edge steps or the like of the housing receiving the dust filter bag 1.
  • the plan shape of the holding plate 2 shown in the figures is long and rectangular. It is conceivable to provide the holding plate 2 with support ribs and / or with orientation features for safe, correct positioning.
  • the paper dust bag 3 is glued to the lowest layer 7.
  • This lowermost layer 7 has an almost circular opening 8.
  • the layer 6 arranged above this layer 7 is of the same shape and area as the layer 7 and also has a breakthrough 9 arranged coaxially to the opening 8, which also has the same radius as that Breakthrough 8 has.
  • Shaped to the third layer 6 is a stabilizing part in the form of a tongue 10.
  • this likewise consists of a cardboard paper material, like the other layers of the holding plate second
  • a rubber seal 11 is gripped between the lowest layer 7 and the layer 6 of the holding plate 2 arranged above it.
  • the rubber seal 11 is secured by gluing between the layers 6 and 7.
  • the rubber seal 11 extends in a ring shape inward and has an inner opening edge 13.
  • the tongue 10 has an extension, starting from the opening edge 12 into the interior of the opening 9, which corresponds to approximately half the extension of the rubber seal 11 from the opening edge 12 into the interior of the opening 8.
  • the task of the tongue 10 is to hold down the rubber seal 11, i.e. H. counteract any protrusion of the rubber seal 11 through the opening 9.
  • the layer 5 arranged above the layer 6 is designed as a spacing layer for the layer 4 forming the ceiling and serves to form a space 14 that is closed on all sides.
  • FIG. 6 shows a top view of the layer 5, leaving out the layer 4 that lies above this layer 5. To indicate that these layers are glued to one another and are therefore connected the section plane, insofar as it matches the gluing, is shown in hatched representation.
  • the layer 5 is essentially designed as a peripheral edge strip that has the same outer contour as the other three layers. Specifically, this is solved in such a way that the layer 5 forms a frame, the frame legs of which have a width of 8-10 mm in the plane extension.
  • the free space 14 formed within this frame also includes the area of the openings 8 and 9 of the layers 7 and 6, so that there is free space coaxially with these openings.
  • the frame-like layer 5 is glued to the layers 6 and 4 on both sides, so that there is a stable configuration of the holding plate 2.
  • the top layer 4 forming the ceiling has the same shape and almost the same surface area as the bottom layer 7.
  • an opening 15 is provided coaxially with the openings 8 and 9. These openings 8, 9 and 15 form the holding plate opening 16 for the entry of a suction pipe of the vacuum cleaner in the operating position.
  • a closure element in the form of a closure slide 17 is inserted displaceably in the area of the free space 14.
  • the latter essentially consists of a closure plate 18 and a longitudinal extension of the holding plate 2 aligned slide handle 19 together.
  • the task of this slide valve 17 is to close the opening 16 of the holding plate 2 in a way that is intentional.
  • the closure plate 18 is moved into the area of the opening 16, this between the openings 9 and 15 of the layers 6 and 4.
  • the slide handle 19 is viewed in an open position of the closure slide 17 (cf. FIG. 1) at that of the opening 16 opposite side of the closure plate 18 arranged on this.
  • the closure plate 18 has a width measured transversely to the direction of displacement R, which corresponds approximately to the clear distance in the area of the free space 14 between two frame legs of the position. In the course of a displacement of the closure slide 17, it experiences lateral guidance in the region of the closure plate 18 through the frame legs of the layer 5.
  • the slide arm 19 extending away from the closure plate 18 has a width measured transversely to the displacement direction R, which corresponds to approximately two thirds of the width of the closure plate 18.
  • the slide arm 19 extends into the rear area of the free space 14 facing away from the opening 16 —in an open position as shown in FIG. 1 — the slide arm 19 being enlarged in the width direction in this end area.
  • a width is selected which corresponds to that of the closure plate 18, which also provides lateral guidance on the frame legs of the layer 5.
  • a recess 21 is provided in the middle of the width extension, which is open at the edge, approximately square in plan, and extends in the direction of the opening 16.
  • the latter has a web-like stop 22 in the center, that is to say in the region of a longitudinal central axis aa of the holding plate 2, pointing towards the rear end of the free space 14, the length of which, viewed in the longitudinal extent of the holding plate 2, is approximately half that of the likewise lengthwise extension of the holding plate 2 considered depth of the recess 21 corresponds.
  • the web-like stop 22 has a length of approximately 6 mm, the depth of the recess 21 corresponding to approximately 12 mm.
  • the width of the web-like stop 22 corresponds to approximately a quarter of the total width of the recess 21.
  • the stop 22 has a width of 4 mm and the recess 21 has a width of approximately 16 mm.
  • this slide-side stop 22 comes into contact with a stationary, also web-like stop 23.
  • the stop edges of the stops 22 and 23 form an angle beta of 90 ° with the direction of displacement R, so that the stops abut each other.
  • the fixed stop 23 is — in relation to the abutting edge in the open position — a mirror image of the stop 22, so that the addition of the lengths of stop 22 and 23 corresponds approximately to the depth of the recess 21 (see FIG. 6).
  • an embodiment is preferred in which the addition of the lengths results in a somewhat larger dimension than the dimension of the depth of the recess 21, so that in the open position the closure slide 17 is only on the through the stops 22 and 23 formed stop A supports.
  • the stops 22 and 23 form a common web 26 'in the open position according to FIG. 1, which is severed in the middle to form the stops.
  • each stop 24 is assigned a fixed stop 25 arranged on the inside of a frame leg of the second layer 5. In an open position according to FIG. 1, the stops 24 are supported on the respective fixed stops 25 to form stop points B and C.
  • the stops 24 and 25 jointly form a web 26 which is used to form the two stops 24 and 25 is severed in such a way that a stop edge 27 of the intermediate stop 28 formed in this way and an edge 29 of the stop 24 on the slide slide side enclose an acute angle alpha of approximately 45 ° with the displacement direction R.
  • the orientation of this dividing line is chosen so that only a displacement of the slide slide 17 from the stop position into the closed position according to FIG. 7 can take place.
  • the intermediate stop 28 lies in the direction of displacement R of the closure slide 17 within the diameter of the holding plate opening 16, i. H. the clear distance between the two web-like intermediate stops 28 is smaller than the diameter, in particular the width dimension of the opening 16.
  • the intermediate stop serves not only to define the open position but also to define the closed position.
  • the closure slide 17 is displaced in the direction of displacement R in such a way that the closure plate 18 closes the holding plate opening 16 by the closure plate 18 being pushed between the opening 15 in the position 4 and the opening 9 in the position 6.
  • the locking position is limited by the stop.
  • the slide slide 17 moves until the slide foot 20 comes into contact with the intermediate stop 28 or the stops 25 on the rear.
  • the closure plate 18 closes the opening 16 entirely, a gap 30 remaining due to the defined end position between an end edge 35 of the closure plate 18 and the frame leg of the layer 5 associated therewith. Any dirt particles or the like, which can accumulate in the region of the opening 16, can be displaced into this gap 30 by the closure plate 18. This serves to increase functional reliability.
  • the top layer 4 already mentioned has circular, window-like openings 31 in the area of the stop points A, B and C in order to expose the respective stop.
  • the diameter of these window-like openings 31 is in each case dimensioned such that the stops located underneath are exposed over their entire web width.
  • This configuration according to the invention is also used to ensure that during the production process of the holding plate 2, the closing slide 17 is initially operated via the Crosspieces 26 and 26 'remain firmly connected to the layer 5 and are only separated from the layer 5 in a final work step by means of a knife or the like, which passes through the circular openings 31, in order to release the displaceability.
  • the cuts are made in accordance with the stop edges to be formed and already described, that is to say at the stop point A transversely to the longitudinal extent of the holding plate 2 and in the area of the stop points B and C at an acute angle alpha of approximately 45 ° to the direction of displacement R.
  • the closure slide 17 Bars that stop during the production process thus serve as stops immediately after they have been severed.
  • the holding plate 2 in its uppermost position 4 has a separate opening 32, which is elongated in rectangular shape in plan. As can be seen from Fig. 1, this separate opening 32 is arranged in the center of the layer 4 and partially releases the underlying slide valve 17.
  • the slide handle 19 is partially underneath, which is provided with a form-fit recess 36 in the form of a slot 33 for a vacuum cleaner-side closure actuating element.
  • This slot 33 is formed as a through opening, which in turn makes the third layer 6 visible through this slot 33.
  • the slot 33 extends transversely to the direction of displacement R and has a length l, which corresponds approximately to the width B of the separate opening 32, however the length l of this slot 33 is chosen to be less than the width x of the slide handle 19 measured in the same direction. Specifically, in the exemplary embodiment shown, the dimension is chosen such that the slot has a length l of approximately 20 mm compared to that measured in the same direction Width x of the slide handle of approx. 30 mm.
  • slot width r measured in the direction of displacement R — is dimensioned approximately with a quarter of the length l of the slot 33.
  • a closure actuating element on the vacuum cleaner side enters this slot 33 and, with the aid of this positive fit, shifts the closure slide 17 into the closure or opening position.
  • the length L of the separate opening 32 measured in the direction of displacement R, is so large that this displacement path, in the exemplary embodiment shown approximately 45 mm compared to approximately 60 mm of the length L, can be traced.
  • FIG. 7 The closed position is shown in FIG. 7 in a top view. It can be seen that viewed between the separate opening 32 and the holding plate opening 16 in the longitudinal extent of the holding plate 2, a sufficiently large web 38 remains. The stability even in the uppermost layer 4 is thus given.
  • the holding plate 2 has continuous circumferential bonding of at least 8 mm over all four layers 4 to 7.
  • Each existing layer 4 to 7 thus contributes to the strength of the holding plate 2.
  • the gluing over all cardboard layers 4 to 7 is on the long sides executed so that the layer 5 in the area of the slide 17 can act as a kind of "track” with a "rail” on each of the two long sides.
  • These "rails” are additionally stabilized with continuous gluing over all four layers 4 to 7 on the narrow sides of the holding plate 2.
  • the forces introduced into the holding plate 2 can be increased without the holding plate 2 deforming appreciably.
  • connection of the slide valve 17 via the three massive, the later stops forming webs 26, 26 'to the layer 5 has the further advantage that the connection can be maintained over the entire production process of the holding plate 2 and beyond the production process of the complete dust filter bag and only has to be solved in a last step. This avoids all production problems associated with a part that is not fixed in position. This prevents, for example, jamming of layers which have already been punched out and are punched out, since the locking slide 17 firmly connected via three points cannot protrude from the plane of the layer 5 to which it is connected.
  • connection of the closure slide 17 is cut through three cuts at angles of 90 °, 45 ° and 315 ° (based on the longitudinal extent of the holding plate 2 in the direction of the opening 16), through the circular openings 31 in the top layer 4.
  • the three Cuts taken together give the shape of a blunted arrowhead.
  • the design for coupling a closure actuating element as a slot 33 has the particular advantage that the safe actuation of the closure by a closure mechanism does not depend on the quality of the bonding of various cardboard layers, as is known from the prior art, averaged over a relatively small area. Furthermore, the friction of the slide slide 17 is not directly increased by the normal force impressed on the holding plate by the locking mechanism. The latter is rather derived through the slot 33 to the third layer 6 arranged below the slide slide 17. Thus, no further force is applied to the slide valve 17, which would lead to increased friction of the latter.
