Definitions
- the invention relates to a dust filter bag made of flexible, foldable filter material, with a bag jacket, the two mutually opposite, extending in the longitudinal direction of the bag Flat walls and two the flat walls on the sides of the bag interconnecting folding walls, each one extending in the longitudinal direction of the bag, facing inwards Main fold with two on one inside main fold apex interconnected main fold legs form, has, so that the bag during operation from a flattened initial shape under unfolding of the folding walls inflated, and with an end-sided, rectangular Block bottom, which is attached in one piece to the bag jacket is and two flat wall floor parts each facing a flat wall and two folding wall floor sections each facing a folding wall has, the two of each one Flat wall extension formed flat wall floor parts each over a flat wall folding edge to the facing one Flat wall and the two folding wall floor sections each the respective main fold via a folding wall folding edge Triangular transition area of the relevant folding wall are attached.
- Such dust filter bags are especially for one on one Hand-held machine tool removing material, for example Grinding machine, with an integrated dust extraction device thought the removal of material to a dust outlet opening on the machine to which the filter bag is conveying connected for example via a connector attached to it is so that the dust air through a connection opening can enter the filter bag.
- the one that forms this Filter material retains the dust inside the bag while the dust-free air through the filter material got outside.
- the dust filter bag In the initial state, the dust filter bag is folded flat. In operation, it becomes the one entering it Airflow inflated, the maximum possible filling volume and the effective filter area through the unfolding capacity of the Folding walls is determined.
- the present invention has the object based on a dust filter bag of the type mentioned kind with larger and larger filling volume since then to create effective filter area.
- the folding walls at least to one side of the main fold between this and the facing flat wall at least one to the main fold parallel additional fold with two additional fold vertices running on the inside have interconnected additional fold legs, the end facing the block bottom on the facing Flat wall fold edge converge, with extensions of the additional fold legs together with the respective flat wall floor section forming flat wall extension on the flat wall folding edge are bent and reinforcements of the flat wall floor part form.
- main fold present formed at least one additional fold so that the bag continues than can be expanded since then and one of the additional fold legs appropriate enlargement of the effective filter area receives.
- the two exemplary embodiments differ in that in the embodiment according to FIGS. 8 to 11 on each folding wall not just on one side of the main fold but on both sides the main fold has an additional fold. Otherwise there is agreement. Therefore, the following is for the embodiment 8 to 11 with the exception of the second Additional fold the same reference numbers as for the filter bag 1 to 7 used.
- the respective dust filter bag 1 or 1a consists of flexible, foldable filter material, for example made of paper-like material It is an originally flat material, the longitudinal edges of which along an interface, not shown be glued so that a tube-like piece of filter material arises, which is then folded into a filter bag.
- the filter bag 1 or 1a has a bag jacket 2, which of two opposite each other and in the longitudinal direction of the bag 3 extending flat walls 4.5 and two of the flat walls 4.5 formed on the bag sides interconnecting folding walls 6,7 becomes. While the flat walls 4.5 have a flat shape, contain the two folding walls 6, 7 each in the longitudinal direction of the bag 3 extending main fold 8 and 9, the inside is directed between the two flat walls 4.5 and two Main fold legs 10,11 and 12,13 is formed on a inside main fold apex 14 and 15 connected to each other are, i.e. merge into one another, so that each one results in a V-shaped fold in cross section.
- the bag jacket is 2 folded flat, i.e. the two flat walls 4, 5 and main fold legs 10, 11 and 12, 13 arranged between them take at least one additional fold, which will be explained later a layer on top of each other.
- the filter bag 1 or 1a i.e. whose bag jacket 2 is on one of its two ends closed by the flat walls 4,5 and the fold legs of the fold walls arranged between them are folded into a folded wrap 16.
- the folding wrap 16 is fixed by gluing.
- the filter bag 1 or 1a a block floor 17, also called block floor, on a rectangular Has peripheral shape and contains a connection opening 18.
- the block bottom 17 carries a rigid material, for example Carton, existing connector 19, which is only in 11 is indicated by dash-dotted lines.
- the connector 19 is glued to the block bottom 17 and contains an aligned to Connection opening 18 arranged passage opening.
- the connector 19 makes the thin, flexible filter material Block bottom 17, so to speak, stable and provides in use of the filter bag the connection to the dust extracting Device forth, with a device-side connector through the Through opening of the plate-shaped connector 19 in the Connection opening 18 of the block bottom 17 is inserted.
- the block bottom 17 is attached in one piece to the bag jacket 2 and is made by appropriately folding the end portion of the tubular Output filter material piece shaped.
- the block bottom 17 In the width direction 20 of the filter bag, the block bottom 17 is the same width as that Flat walls 4.5.
- the other two rectangular sides of the block bottom 17 are the same length as the stretched width of the same two Main folds 8.9, the stretched main fold width being the sum of the inwardly extending width dimensions 21, 22 of the corresponds to both main fold legs 10, 11 and 12, 13 respectively. Are there the two width dimensions 21.22 are the same size.
- the block bottom 17 is essentially distributed over the circumference by four Bottom parts formed, each one of the sides of the rectangle extend along.
- Two are each a flat wall 4 or 5 facing flat wall floor parts 23, 24 and two each a folding wall 6 or 7 facing folding wall bottom parts 25, 26 are present.
- the floor sections 23, 24, 25, 26 are each one folded extension of the relevant bag wall 4, 5, 6 or 7 educated.
- These wall extensions are the in FIGS. 2, 3, 9 and 10 end sections facing the viewer of the individual walls, which are not included for reasons of clarity Reference numerals have been provided.
- the two flat wall floor parts 23, 24 are each one Flat wall folding edge 27 or 28, which extends over the flat wall width (Width direction 20) extends to the respective facing Flat wall 4 or 5 attached.
- the two folding wall floor parts 25, 26 on the other hand connect via a folding wall folding edge 29 or 30 one end of the respective main fold 8 or 9, triangular transition area 31 or 32 of the relevant flat wall 4 or 5. It’s an isosceles triangle, whose base corresponds to the folding wall folding edge 29 or 30.
- the two triangle legs 33, 34 are formed by fold lines, starting from the two facing corners of the block floor 17, meet at the main fold apex 14 or 15.
- the block bottom 17 takes one approximately parallel to the bag casing 2 (see FIGS. 1 and 8, in which the block bottom 17 for clarity below is drawn at an acute angle to the bag jacket 2). To do this the block bottom 17 around a flat wall folding edge 27 to the opposite Flat wall 5 folded, which is a kink 35th receives.
- the floor parts 23, 24, 25, 26 cover the surface of the block floor 17 not completely but leave the connection opening 18 free.
- the bottom parts 23, 24, 25, 26 have a strip-like shape on.
- the folding walls 6.7 at least one additional fold parallel to the main fold 8.9 form. Through these additional folds, the filter bag in the Unfold position of use further so that it has a larger filling volume and also receives an enlarged effective filter area.
- an additional fold gives the folding walls a zigzag-like appearance trending cross section.
- the two additional folds 36, 37 are each on one side the main fold 8 or 9 belonging to the same folding wall 6 or 7 between the main fold 8 or 9 and the facing flat wall 4 or 5.
- the additional pleats 38, 39 of the exemplary embodiment 8 to 11, on the other hand, are on the respective folding wall 6 or 7 to the other side of the main fold 8 or 9 between the Main fold 8 or 9 and the facing flat wall 5, so that with each folding wall the main fold between the two additional folds runs.
- Each additional fold 36,37,38,39 corresponds to the main folds each of two additional fold legs 40.41, 42.43 and 44.45 and 46.47 formed on an additional fold vertex running on the inside 48 or 49 or 50 or 51 are connected to each other.
- the additional folds can be of the same width be like the main folds, i.e. into the bag extend into it.
- the two additional fold legs merges so that they face each other Flat wall folding edge 27 or 28 converge.
- the Additional fold legs like the flat walls 4,5 over the place of Flat wall folding edge 27 or 28 also extended, the extensions the additional fold leg together with the flat wall extension, the respective flat-wall floor section 23 or 24 forms, are bent at the flat wall folding edge 27 or 28, so that they reinforce, so to speak, the flat wall floor part form.
- the pair of additional folds adjacent to the respective flat wall 4 or 5 is held together at the end with the respective flat wall, so that the extensions of the additional fold legs and the associated flat wall together to the floor section 23 or 24 fold over.
- the floor parts obtained in this way are included the folding wall-floor parts glued 25,26.
- FIGS. 2 to 7 forth The various forming steps are shown in particular in FIGS. 2 to 7 forth.
- 2 shows the same throughout permanent cross-section, tube-like initial filter material piece, in which the main folds 8.9 and the additional folds 36.37 are already formed.
- 3 is the parallel Put the additional folds together on the facing flat wall 4 forth.
- the width of the bottom parts to be molded appropriate distance to the end of the two triangular ones Transitional areas 31,32 folded to the main folds 8,9, so that the wall ends or their extensions resulting in the floor parts superscript, as indicated in Fig. 4.
- folds first, for example, the two folding wall floor sections 25, 26 and then the two flat wall floor parts 23, 24 inwards, so that the block bottom 17 results. It is understood that this Steps flow smoothly into one another.
- the filter bag according to FIGS. 8 to 11 becomes corresponding manufactured.
- the block bottom 17 can also be closed trained and the connection opening through which the dust air occurs at another location, e.g. on one of the flat walls 4, 5, may be arranged.
- a closed block floor can be obtained, for example, by way of Floor elongated floor sections 23, 24, 25, 26 so that they overlap, or at one of the connection openings shown corresponding opening leaving the floor areas open Stick on a piece of material that closes the opening e.g. foil-like shape.
- the rigid connector 19 could be missing, for example be replaced by a perforated piece of film.
