Definitions

  • the invention relates to a dust filter bag for vacuum cleaners, in the form of a block bottom bag, with a two opposing flat walls forming bag body made of flexible filter material and arranged at one of the longitudinal ends of the filter bag, a passage opening holding plate for holding the filter bag in the vacuum cleaner, the bag body two each attached to one of the flat walls and end mutually connected bottom parts, which are arranged below the holding plate and form a fixed to the holding plate connected bag body bottom, so that in the position of use, the holding plate is transverse to the flat walls and the flat walls are kept at a distance from each other, wherein the holding plate is arranged on the outside of the first of the two bottom parts and the second bottom part has an inwardly folded, laid against the inside of the first bottom part and extending along the holding plate Forming bottom fold and wherein the bag body bottom has a passage opening of the holding plate adjacent entrance hole assembly.
  • Block bottom bags also called block bottom bags, are used both in household vacuum cleaners and in commercially used vacuum cleaners.
  • a suction flow is generated by means of a vacuum cleaner fan, which loads the loaded with the dust or the like particles of air into a suction hose and from there through the passage opening of the holding plate and the inlet hole arrangement of the bag body bottom promotes into the bag interior.
  • the particles contained in the intake air are retained by the filter material wall of the bag body. The dust-free air penetrates the bag wall and is blown into the environment.
  • Block bottom bags are usually closed at one of their longitudinal ends, for example, by attaching a weld seam or a folding wrap produced by repeated folding and gluing and at the opposite longitudinal end have a holding plate which connects to the vacuum cleaner.
  • the bottom fold extends at least over the width of the holding plate and passes into a resting on the outside of the dust bag overfolding. This results in a correspondingly large amount of material.
  • the present invention has for its object to provide a dust filter bag of the type mentioned, which not only has a relatively simple structure but as little as possible filter material is required for its production.
  • first bottom section includes a first entrance hole and that the bottom fold of the second bottom section is folded so far inward that its pleat crest is arranged approximately in the middle of the first inlet hole.
  • the two each attached to one of the flat walls bottom parts are substantially the same size. If the holding plate and the first bottom part, for example, the same width and the passage opening of the holding plate in the width direction centered, also only one in the width of the holding plate corresponding material area is required for the second bottom part, so that you can make do with a minimal cost of materials.
  • the pleat crest can run continuously over the first entry hole.
  • the two pleat limbs of the second bottom part, which merge into each other at the pleat crest each contain an entry half hole emanating from the pleat crest, so that the two entry halfholes merge into one another at the pleat crest, with the two inlet halfholes adjacent to the facing half of the first entrance hole are arranged.
  • the air flow can enter the bag interior, since one half of the inlet hole of the first bottom part opens directly into the bag interior and in the former case, the bottom fold is pushed away either by the air flow or arranged on a vacuum cleaner connection, while in the latter case the other Half of the inlet hole is arranged in alignment with the inside of the bag facing, overlapping inlet half-holes of the second bottom section.
  • resulting dust filter bag 1 has the shape of a block bottom bag (this type of bag is called in practice also block bottom bag) and is composed of a bag body 2 and arranged at one longitudinal end 3 of the filter bag 1 holding plate 4 together.
  • the bag body 2 is made of flexible filter material, which may be one or more layers.
  • the type of filter material is of minor importance in the present case.
  • the holding plate 4 is rigid and made of plastic. It serves to set the filter bag 1 in a vacuum cleaner, which has a corresponding receptacle for the retaining plate.
  • the holding plate 4 has substantially the shape of an elongated rectangle.
  • the longitudinal direction of the holding plate 4 and thus the longitudinal edges 6, 7 extend transversely to the longitudinal direction 8 of the filter bag 1.
  • the holding plate 4 is in FIG. 3 only schematically drawn. It is formed in the embodiment of an injection molded part and can have the material savings openings and for fixing in the vacuum cleaner on the circumference protruding projections.
  • the holding plate 4 further includes a passage opening 9 for the passage of the sucked air from the vacuum cleaner.
  • the bag body 2 forms two mutually opposite flat walls 10, 11, which have a rectangular shape in the present embodiment.
  • the ends 14, 15 are connected together. This can be done for example by gluing or by means of a glued Faltwickels or in particular by welding.
  • the two bottom parts 12, 13 integrally merge into each other, so that the two flat walls 10, 11 can be formed together with the two bottom parts 12, 13 of a one-piece filter material.
  • the two bottom parts 12, 13 are arranged in the finished filter bag 1 below the support plate 4 and form a firmly connected to the support plate 4 bag body bottom 16. In this way it follows that in from the FIGS. 7 and 8 Outstanding position of use, the holding plate 4 transversely to the projecting from the support plate 4 flat walls 10, 11 and the flat walls 10, 11 holds at a distance to each other.
  • the flat walls 10, 11 are welded together or fixedly and tightly connected to each other by a glued Faltwickel.
  • the two flat walls 10, 11, as shown FIG. 8 it can be seen in the direction of the transverse holding plate 4 pointed away from each other away.
  • the two bottom parts 12, 13 are in the position of use in each case along a bending line 20 and 21 at an angle from the facing flat wall 10 and 11 from.
  • the filter bag 1 is folded flat by the holding plate 4 together with the bag body bottom 16 around one of the two bending lines, conveniently around the bending line 20 as a pivot center in the direction indicated by arrow 18 to the outgoing from the bending line 20 flat wall 10 turns back.
  • the other flat wall 11 is bent accordingly.
  • the bag body bottom 16 has one of the passage opening 9 of the holding plate 4 adjacent inlet hole assembly 19, so that the sucked dust air passes through the passage opening 9 and the inlet hole assembly 19 into the bag interior.
  • the particles contained in the dust air are retained by the wall of the bag body 2.
  • the freed from the dust particles air passes through the wall of the bag body 2 through to the outside.
  • the holding plate 4 is arranged on the outside of one of the two bottom parts of the bag body 2, in this case on the attached to the flat wall 10 bottom portion 12 and fixed, in particular by gluing connected thereto, so that not only results in a solid cohesion but at the same time the transition from the passage opening 9 of the holding plate 4 is sealed to the entrance hole assembly 19 of the bag body bottom 16 to the outside.
  • the first bottom part 12 extends, starting from its bending line 20, over the passage opening 9 of the holding plate 4 away and contains a first inlet hole 22, which is part of the inlet hole assembly 19 and aligned with the passage opening 9 of the holding plate 4.
  • the second bottom part 13 forms an inwardly folded against the holding plate 4 facing away from the inside of the first bottom section 12 and along the support plate 4 extending bottom fold 23 with two fold legs 24, 25, which merge into one another at a fold crest 26.
  • a pleat leg 24 extends from the bending line 21, at which the second bottom part 13 to the Flat wall 11 is attached, to the pleat crest 26.
  • the other pleat leg 25 extends from the pleat crest 26 to the end 15 of the second bottom portion 13th
  • the bottom fold 23 is folded inwards to such an extent that its pleat crest 26 is arranged approximately in the middle of the first entry hole 22 of the first bottom section 12 so that the pleat crest 26 extends approximately along the diameter line of the first entry hole 22 extending in the longitudinal direction 5 of the support plate 4 runs.
  • the two pleat legs 24, 25 each contain an outgoing from the pleat crest 26, i. on the pleat leg 26 open-edged inlet half-hole 27, 28.
  • the two inlet half-holes 27, 28 thus go on the pleat crest 26, so to speak into each other and overlap.
  • the two inlet half-holes 27, 28 are further arranged adjacent to the facing half of the first inlet hole 22, so that the inlet hole assembly 19 on the one hand of the pleat crest 26 of the bending line 20 facing half of the passage opening 9 of the holding plate 4 and the other part of the pleat crest 26 of the bending line 20 remote half of the passage opening 9 and the two aligned with this inlet half-holes 27, 28 of the second bottom part 13 is formed.
  • the pleat leg 24 facing the first floor section 12 is firmly and tightly connected to the first floor section 12. Furthermore, the two pleat legs 24, 25 are solid and tight connected with each other.
  • the respective bonding is advantageously carried out by gluing, in particular by hot gluing.
  • the ends 14, 15 of the two bottom parts 12, 13 are firmly connected to each other.
  • the two bottom parts 12, 13 are expediently connected to one another in the vicinity of the respective longitudinal edge 7 of the retaining plate 4.
  • the holding plate 4 and the bag body bottom 16 are at right angles to the longitudinal direction 5 about the same width. Further, the arrangement is suitably made so that the passage opening 9 of the support plate 4 in the width direction of the support plate 4 is centrally located on this and the first entrance hole 22 in alignment with the passage opening 9 and that the pleat crest 26 of the bottom fold 23 extends in half the width of the support plate 4.
  • the filter bag 1 has on both sides thereof in each case a side fold 30, 31 folded inwards between the two flat walls 10, 11 over its entire length, in the use of the filter bag 1, when it inflates through the air sucked in, is everted, so that the bag volume increases accordingly.
  • an initial bag 32 (see Figures 1 and 2 ), which is formed by two equal sized and identically contoured blank material pieces 33, 34 of the filter material, which are superimposed and welded together along its peripheral edge, so that a circumferential weld 35 is formed, which consists of successive weld seam areas composed.
  • One of these weld seam regions, the weld seam region 47 connects the two ends 14, 15 of the two bottom parts 12, 13 in the finished filter bag 1.
  • Another weld seam region, the weld seam region 48 connects the two at the finished filter bag 1 on the longitudinal side 17 of the holding plate 4 Flat walls 10, 11 with each other.
  • Each of the two cut material pieces 33, 34 forms a flat-wall material region 37, 38 which results in the finished filter bag 1, a bottom-end material region 39, 40 resulting from the respective bottom part 12, 13 and a gusset leg on each side.
  • a through recess 45 is attached through both bottom part material areas 41, 42, which in the finished filter bag 1 on the one hand the first entrance hole 22 of the first bottom section 12 and on the other hand, the second inlet hole 29 of the second Floor lot 13 results.
  • the two inlet holes 22, 29 are thus produced in a single step and are inevitably aligned with each other. From the second entry hole 29 later arise the two already mentioned entry half-holes 27, 28th
  • the two side folds 30, 31 are folded inwardly between the two flat-wall material regions 37, 38.
  • the one side fold 30 is formed by the two side fold leg material areas 41 and 43 and the other side fold 31 is formed by the two other side fold leg material areas 42, 44.
  • the two lateral weld seam areas 49, 50 yield, after the folding in of the lateral folds 30, 31, their side-fold peaks 51, 52.
  • the holding plate 4 is attached to the bottom-portion material region 39 of the blank material piece 33, so that the out of the FIGS. 3 and 4 resulting intermediate bag 53 results.
  • the bottom plate material region 40 of the other flat-wall material region 38 facing away from the holding plate 4 is folded in, so that the bottom fold 23 is formed.
  • This folding process is over FIG. 6 seen.
  • the first bottom-part material region 39 which carries the holding plate 4, bends off the flat-wall material region 37 at the bending line 20.
  • the bottom fold legs 24, 25 are completely folded and placed against the first bottom section material region 39 or the first bottom section 12.
  • the two bottom pleat legs 24, 25 are glued together and the side pleat leg 25 with the first bottom section 12.
  • the second bottom part 13 has a bottom fold crest 26 corresponding Sollfaltline 54.
  • This desired fold line 54 can be formed by a weld line which has been introduced into the respective cut piece of material 34.
  • At least one of the two bottom pleat legs in the expedient embodiment of the base pleat leg 24 facing away from the support plate 4, is solidified in itself, in particular by hot stamping.
  • This solidification already takes place in the blank material piece 34, as shown in FIGS Figures 2 and 4 evident.
  • This is the solidification zone 55 shown with cross-hatching.
  • This material consolidation does not yield only a stable counter surface when gluing the bottom fold legs 24, 25 but also prevents damage to the filter material during hot bonding.
  • the layers of material forming the second bottom section 13 may be connected to one another in a punctiform and / or line-like and / or planar manner, so that the material layers can not shift relative to each other when the bottom fold 23 is folded.
  • the joining of the material layers by welding or gluing takes place.
  • this joining of the material layers on the one hand of the bottom pleat crest 26 takes place through the solidification region 55 - if such a solidification region were missing, for example, would suffice a weld line - and on the other hand the bottom pleat crest 26 through a weld line 56.
  • the two pleat legs 24, 25 of the bottom fold 23 each have an entrance half-hole 27, 28 originating from the pleat crest 26, so that the two entry half-holes 27, 28 merge at the pleat crest 26, the two entry pleats 26 Half holes 27, 28 adjacent to the facing half of the first entrance hole 22 are arranged.
  • these half-holes 27, 28 can also be omitted so that the pleat crest runs uninterruptedly over the first entry hole 22.
  • This embodiment is readily conceivable, so that was dispensed with a separate presentation.
  • the area of the bottom fold crossing the entry hole 22 is pushed aside by the incoming air flow or a connection piece arranged on the vacuum cleaner, inserted through the entry hole 22, so that the air practically undisturbed passes into the bag interior.
  • the omission of the entry half-holes lowers the manufacturing costs, since the punching of the second bottom portion 13 and the sealing bonding of the pleat legs 24, 25 omitted.
