Description

The invention relates to a vacuum cleaner with a receptacle and received therein, having a retaining plate Dust filter bag (see US-A-2 864 462), wherein at the receptacle a Closing plate formed with an actuating projection is, for actuating a an opening to the nozzle connection in a fan air duct of the vacuum cleaner on the dust filter bag occlusive closure element the holding plate, wherein further the actuating projection Federbar in its extension direction is formed and a total of pivoting.

For the appropriate interaction of the vacuum cleaner with the Dust filter bag proposes the invention that the Actuating projection in the course of pivoting the closure element regarding the Relocated opening, by cooperation of the actuating projection with a manipulation projection, formed at an opposite end of the opening Closure element.

The opening of the dust filter bag in the area of the holding plate for a suction pipe of a vacuum cleaner can by means of the closure element both closed as also be opened, wherein the closure element in the Closure position and in the open position in one Outer contour of the holding plate practically completely absorbed is and that the closure element in one of the opening separate recess of the uppermost layer exposed, wherein a longitudinal extent of the recess adapted to a displacement of the closure element is. It is also preferred that at least three times arranged cardboard paper material layers of the holding plate a layer a support for the closure element in the open position forms. The closure element is designed in size so that this both in the Closure as well as in the open position in the outer contour the holding plate is completely absorbed. This is achieved, for example, in that the closure element one of the opening of the holding plate adapted Closure surface with arranged thereon handle has which closure surface for the production of Closure position in the region of the opening of the holding plate is relocated. The minimalest displacement corresponds to the diameter of the opening of the Retaining plate. To an accidentally closed To open the dust filter bag again, the closure element shifted so that the closure surface the Area of the opening of the holding plate at least as far leaves that the suction pipe of the vacuum cleaner introduced can be. The size of the closure element is hereby chosen so that the movements within the outer contour of the holding plate done. A safe Leadership of the closure element is characterized ensures that at least three fixed One sheet of cardboard material layers of sheet one layer a substantially full surface support for the Closing element forms. In a preferred embodiment the arrangement is such that the full-surface Supporting the closure element both in the Open as well as in the closed position is formed. Deviating from the full-surface support can also a contoured support may be provided, extending itself for example with regard to reducing friction can. For improved handling of the closure element to reach, lies the closure element in one of the opening separate recess of the uppermost Location free, with a longitudinal extension of the recess to a displacement of the closure element is adapted. The in the separate recess of the top layer exposed area of the closure element serves as a handle. This area can both gripped by hand and mechanically in the course subjected to opening or closing of the vacuum cleaner become. Preferably, the training of the Closing element owning holding plate so chosen be that the latter consists of three fixed layers, where the middle layer has a recess for receiving the closure element having. The width of the recess corresponds to the width of the closure element. The length of the recess, however, results from the Length of the closure element plus the displacement, which at least the diameter of the to be closed Opening corresponds. The middle, the closure element receptive situation can thus be considered as all four sides be formed closing frame. The lowest Location forms here a full-surface support for the closure element. Around the opening of the retaining plate close tightly when entering the suction tube, is in the preferred embodiment another, below the lowest layer arranged position provided between which two layers a seal in the area the opening rests. It is thus a lockable Dust filter bag created for a vacuum cleaner, the handling technology is optimized. The closure element is in the closed and in the open position in the outer contour of the holding plate completely absorbed. Neither in the two end positions nor in one Intermediate position protrude portions of the closure element beyond the outer contour of the retaining plate. Various Vacuum cleaners provide in the area of intake the holding plate of the dust filter bag no clearance for entering an over the outer contour of the retaining plate protruding portion of the closure element. Of the Dust filter bag can, however, in one such vacuum cleaners are used and here mechanically in the course of opening or closing the vacuum cleaner closed or opened. It exists but also the possibility of manual control the closure element by hand. In an advantageous Training is provided that at least one Part of the displacement of the closure element a Closure element edge up to the edge contour of the holding plate or beyond. This embodiment can, for example, in the area of peripheral recesses the holding plate for gripping the latter when removing the dust filter bag formed from the vacuum cleaner be. In the area of these marginal recesses, the Closure element edges up to the edge of the recess extend, with at least part of the Moving path, the closure element here, for example can be moved by means of stapling. There is also the possibility here that the closure element edges over the edge contour in the area of Extend Randausnehmung addition. In a first version the closure element edges extend only very a little, on the order of tenths of a millimeter, beyond the edge recess. In a second version but the extension can also be essential For example, be a few millimeters or even in the Move centimeter range. Especially if a separate displacement projection laterally on the closure element something is formed, which is also possible Alternative represents. Due to this configuration is another way to move given the closure element when, for example, a mechanical defect is present. As already mentioned, is the closure element is mounted between two fixed layers, with a lateral guide through between the two fixed layers arranged webs or the like given is. In the area of these webs can further Stops may be provided, which both the Offenals also the closure position of the displacement element define. Advantageously, the closure element a substantially spade-shaped plan. The spade stem here forms the operating section for the closure element. Here is the lateral support the closure element realized by that between two fixed layers another, only an edge-forming layer is arranged, which as Negative form of the spade-shaped closure element under Considering the displacement is formed. in the Area of transition from the spade stem to the closure surface the closure element are due to the spade-shaped plan, stop edges formed, which against corresponding stop edges of the frame-shaped, the lateral support forming position in the open position to step. In the closed position occurs the Spade stem opposite edge of the closure element against a corresponding area of the Edge forming location. For optimal handling ensure that the spade handle of the Recess is assigned. As already mentioned, the Longitudinal extension of the recess to the displacement adapted to the closure element. advantageously, in this case, the recess has at least one same Width on as the spade handle of the closure element. Alternatively, it is also possible that the spade handle has a greater width than the recess. One- or on both sides of the spade stem moves at this Embodiment in the lower handle to the edges of the recess. In the area of this recess can now as Operating section trained Spatenstiel by hand gripped or moved mechanically. For this purpose can be provided that on the spade handle a manipulation projection is trained. This may be one on the free end of the spade handle arranged thickening or also a recess provided in this area be. In a preferred embodiment, the manipulation projection chosen so that the spade handle a Bendable section has. This section can be grasped in the simplest way by hand. It is also conceivable, a mechanics in the field of ausknickbaren Section to be effective. Preference is given here an education, formed in the two kinks are.

The invention further relates to a vacuum cleaner with a dust filter bag, the dust filter bag a holding plate having an opening for a suction nozzle, wherein the holding plate is a closure element has, in the course of opening the vacuum cleaner automatically displaced into a closed position is.

Such a configuration is also from the already US Pat. No. 2,864,462. Here is the already mentioned closable dust filter bag such inserted into the vacuum cleaner that an actuating projection of the vacuum cleaner in a recess of the free End of the closure element can engage. through this actuating projection becomes the closure element the holding plate in the course of opening the vacuum cleaner automatically shifted to a closed position. It is also known, by means of the actuating projection when closing the vacuum cleaner the closure element act in such a way that a release the opening of the retaining plate of the dust filter bag he follows.

It is envisaged that the actuating projection designed springable in its direction of extension is. Due to this configuration, the actuating projection can also be used with such vacuum cleaners, which has a narrow radius between the pivot axis of the dust filter bag carrying the vacuum cleaner part and the closure element of the other vacuum cleaner part exhibit. With such tight radii it is mandatory necessary that the actuating projection after engagement in the closure element or after its application as a function of the pivoting movement yields. From Of particular importance is the flexibility or resilience the actuating projection also to prevent a self-inhibition or self-blockade. Even if the operating projection once in an unfavorable Angle should hit the dust filter bag, can by the deflection another pan of the Actuating projection carrier (in the individual case of the towing cover, see below) and so the angle of attack between actuating projection and dust filter bag be changed, so that no more self-locking is. The mobility or resilience is in individual solved so that the actuating projection itself in the course of pivoting the dust filter bag in the Use position of the vacuum cleaner in its extension direction can shorten accordingly. This springy Training of the operating tab is also especially advantageous, if not appropriate adapted dust filter bags are used. Especially then when dust filter bags are used, which no device for closing the opening have for the suction. In an advantageous Further development is provided that the actuating projection is formed on a towing lid. One Such drag cover is especially for vacuum cleaners with falling arranged dust filter bags of advantage. Here is the removal of the dust bag Bag chamber swung together with the towing cover. After that, then the actual opening of the bag chamber, by the towing cover like that is pivoted that the dust filter bag released becomes. Here, the trained on the towing cover Actuating projection, the closure element of Holding plate of the dust filter bag such that the opening closed the holding plate for the suction becomes. After that, however, the re-use of this Dust filter bag desired, then the towing cover pivoted back towards the bag holder, wherein the actuating projection in turn the closure element shifted so that the opening of the holding plate is released. It is, however, quite conceivable, the actuating projection directly, i. under Bypassing a towing lid to arrange on the vacuum cleaner. A usage optimization is the further given by the fact that the actuating projection is pivotable against a spring. The second spring (im Difference to the first spring, against which the actuating projection lengthenable) provides in the essentially a closure force for a shift the closure element in the closed position. Especially during an opening process of the vacuum cleaner pushes the second spring, in the course of the opening movement, the actuating projection still forward and thus causes at least the last part of the closure movement the closure element. In addition to the federbaren training of the actuating projection in Extension direction is thus this against a Spring pivotally formed. Furthermore, it is envisaged that associated with the actuating projection registration projections are provided, which after pivoting the actuating projection in registration openings retract the other vacuum cleaner part, wherein a closure of the vacuum cleaner only when retracted Registration tabs is possible. This is to ensure be that closing the vacuum cleaner only with inserted dust filter bag is made possible. If no dust filter bag is inserted, it will find Actuation projection no corresponding support when closing the vacuum cleaner, so that this not shifted from his position, which also with the this associated registration projections in their locked position remain. Will now try the vacuum cleaner Close the registry tabs corresponding blocking areas of the other vacuum cleaner part. However, when the dust filter bag is inserted, it pivots the actuation advantage in the course of closing of the vacuum cleaner, with which also the registration tabs be shifted so that they in the registration openings retract the other vacuum cleaner part can and thus allow the closing of the vacuum cleaner. Advantageously, it is provided that the registration projections at one with the actuating projection firmly connected plate are formed. at Use of a dust filter bag in the already described Art acts on the actuating projection of the vacuum cleaner, the closure element in the region of his Spatenstieles formed as an operating section. Is the spade handle of the closure element with a provided ausknickbaren section, so engages the Actuating projection when opening the vacuum cleaner this bendable section and thus shifted the Closure element in a closed position of the opening the retaining plate of the dust filter bag. Should such a thing closed dust filter bag continue to be used, so acts on the actuating projection of the vacuum cleaner in the course of closing the vacuum cleaner the Area of the bendable portion such that the Closing element is displaced in an open position. It goes without saying that it is also at insertion a normally opened dust filter bag to no disturbances in the function of the actuating projection comes. It is therefore irrelevant whether the dust filter bag in a closed or open Condition is inserted into the vacuum cleaner. In the Displacement of the closure element in the open position may in one embodiment of the actuating projection a manipulation projection on the closure element, preferably the spade stem of the closure element, run over. Even after overflowing this closure lead is the length of the - slightly compressed

Actuating projection not yet fully extended. Rather, it is intended that the actuating projection under certain length shortening (spring deflection) against a housing-fixed stop after overflowing the Manipulation projection abuts. This is also true Meaning that when you first open the suction of the vacuum cleaner from the opening of the filter bag can drive out before then in the course of further Opening or pivoting of the actuating projection mitgeschwenkt, since in the meantime the length stock fully exploited by extending the telescopic Length of the actuating projection. Only then will the opening of the dust filter bag eingeschiebert because now the opening is also free, since the suction nozzle is extended. Moreover, when closing of the vacuum cleaner by the mentioned overflow of the Manipulation projection by the actuating projection and the movement limit of the operating projection by concerns on the housing-fixed projection a striking Clicking sound that also signals to the user that the vacuum cleaner now fully functional is.

The invention further relates to a dust filter bag of the type mentioned in the edge one over provided the opening edge inwardly projecting rubber seal is. Such a dust filter bag is for example known from DE A 1 39 19 256. Next is to State of the art also refer to DE A 1 24 07 478. In the known from DE A 1 39 19 256 Dust filter bag is in a sliding closure part also formed an opening, wherein the Using the dust bag the opening in the holding plate and the opening in the sliding closure member must be brought into a superimposition. The Has opening in the sliding closure member an annular seal. In such a seal it may come in the course of use to the effect that the seal is in a certain way and closing the dust filter bag in the desired shape is then no longer possible. The result resulting problem, such a dust filter bag indicate at which complete closure is assured by it solved, that in overlap with the Rubber seal inward from the opening edge Stabilization is provided. A rubber seal, as it is addressed here, it is not on the material rubber arrives, but this seal also from another elastomeric or comparable Material can exist when using a such dust filter bag through the retracted suction tube experience a certain embossed deformation.

In particular, is often a decrease in the elastic To observe characteristics. This particular if, as is often the case, the dust filter bag with retracted suction tube over several weeks or months remaining in this position. When driving out of the suction tube, it can then turn the in itself protruding into the interior of the dust filter bag Come rubber seal. This then blocks a complete Addicts of the opening. The invention provided stabilization part now ensures that it does not come to this turning or the rubber seal each a forepart towards the interior of the Dust filter bag (down) is abandoned. The Stabilization part can in particular also from the already mentioned cardboard-paper material exist. This also occurs when retracting the suction tube to a kinking of the stabilization part. Here but the stabilization part due to its surface stability when moving the suction tube out of the opening can not fold, remains even after a complete Remove the suction tube from the opening one Alignment of the rubber seal inside the dust filter bag. Suitably, the stabilizing part attached to the location of the opening, which at a closure last of the closure element is run over. In addition, of course, too several such stabilizing parts may be provided or even a stabilizing ring edge, the total is bent over when retracting the suction tube. It is also advantageous if an extension of the stabilizing part inside with respect to the opening edge the opening about half the extent of the rubber seal inward, ie in the same direction. This also requires that the rubber seal with a much larger width than previously pictorial is trained. The stabilization part has rather suitably an extension, which is the hitherto usual width or extent inward of the rubber seal equivalent. Related to a diameter of Opening in the holding plate of the dust bag is the extent of the stabilization part after inside for example 1/10. Accordingly extends the usually annular rubber seal about by the dimension of 2/10 of the diameter of the opening Inside. A retaining plate of a dust filter bag, such as she is talking about, for example, has one multilayer construction. It is made of several layers of Cardboard paper composite. In this relationship the stabilizing part is preferably at an in in direct contact with the rubber seal Position of the holding plate mitangeformt. Also recommends it is, the stabilizing part on a dust bag To arrange the opposite side of the rubber seal. In particular, the stabilization part may also be tongue-like be educated.

The invention is also a generic Vacuum cleaner, in particular with a receptacle for a Dust filter bag, wherein on the recording a Schleppdekkel or a closure plate with an actuating projection is formed, for actuating a slide as a closure element on a dust filter bag, wherein further the Actuate projection in its extension direction Federbar is formed and overall is pivotable against a spring. The pivotability is given relative to the closure plate. In detail reference is also made to EPO 532057, in that regard, as the basic structure of the vacuum cleaner with the receptacle for the dust filter bag and the Retaining plate, which is movably attached to the receptacle is affected.

At this recording is now below the actuating projection formed, which is for actuating a in the Dust filter bag integrated slide or shutter slide serves. With regard to such a dust filter bag is the technical problem, the operation of the slider, acting on the dust filter bag as reliable and safe as possible lowest possible wear attack or more generally Impairment of the dust filter bag and in particular to reach the retaining plate. In this regard proposes the invention that the actuating projection is attached to the closure plate, such that in Course of a compression of the actuating projection at the same time a pivoting is introduced. The connection causes the operating projection to the closure plate, that at a compression, in which first a linear displacement of the actuating slide takes place, the distance between the attachment locations themselves increased. If you now connect to a band or the like, this is streamlined and achieved a state in which it is no longer essential can length. Upon further pressure on the Shutter plate, the actuating projection is therefore on the closure plate attracted to, so that it to the anyway in the course of further operation occurring Pivoting of the actuating projection on the closure plate but sooner, come. Is reached hereby at the same time a pressure limit, as with increasing deflection of the actuating projection in also linear direction through the tip of the actuating projection on the retaining plate of the dust filter bag exerted pressure increased. Due to the connection, the length-limited, a premature termination takes place this compression movement under increased pressure on the holding plate as in a movement without the connection. In a further embodiment, it is provided that the connection from a flexible binding means consists. The attachment means can be a band or a cord.

In a further solution of the problem is also provided that the actuating projection lateral Supporting elements, for supporting on a frame the recording. The lateral support elements can be immediate be formed on the actuating projection. In particular, if this, as preferred, as a plastic injection molded part is trained. The picture forms more preferably for the lateral support a sliding path out. If during the movement of the shutter plate after an initial compression of the actuating projection in its axial direction, the pivoting the actuating projection on the closure plate takes place, the lateral supports slide on from the mentioned glides. It is essential that through these supports a force load, which initially on the retaining plate of the dust filter bag a movement the closure plate of the recording in the closed position is set to a certain value or range is limited. In addition, the power derived from the supports, from the inclusion of the dust filter bag added.

The illustrated electric vacuum cleaner 1 is as a handheld device designed. He has a housing 2, to which above a stem 3 connects with end-side handle. 4 Located in the transition area between handle 4 and handle 3 An on / off switch 5. The electrical cable connection is designated by the number 9.

The housing 2 is divided into a motor housing 6 and an extending chamber 7 for receiving a dust filter bag 8. The engine fan is drawing not shown in detail.

The motor housing 6 facing side of the dust filter bag 8 is in the operating position of the vacuum cleaner according to Figure 1 in connection piece connection to a Blower air duct of the engine fan.

The motor housing 6 goes below into a pipe coupling 10 via which the air flow connection to a Suction nozzle 11 produces.

With respect to the suction nozzle 11 may be a so-called Suction / brush nozzle act in the nozzle mouth a Brush roller contains, via a separate drive is set in rotation.

The fan motor works from bottom to top thus pushes the dust in the above the Motor housing 6 tumbling dust filter bags 8th.

The cross section of the housing 2 is consistently long rectangular with slightly bulging broadsides and the like Narrow sides. In Figure 1, the vacuum cleaner of to see the broadside.

The cross-section corresponding dust filter bag. 8 receiving chamber 7 is of a wire basket stiffened Textile bag 12 is formed, which bottom, i. motor housing side in a stiffened edge in the form of a filter frame 13 passes. The stiffened textile bag 12 can this filter frame 13 by way of releasable clip-in connector be assigned. The attachment area is deducted.

To remove the dust filter bag can be Housing 2 practically under complete release of his Open the cross section. The Aufklappstellung yields from the figures 1 (here in dash-dotted line style), 3, 4 and 11 to 13. Enabling this Folding axis 14 is located on one narrow side of the housing 2. Your filter frame side bearing eyes are designated 15. These bearing eyes 15 are located on Transition area between narrow side and broadside the chamber 7. extends between two bearing lugs 15 a continuous bearing eye of the motor housing. 6

In the area of the parting line of the motor housing 6 and Chamber 7 is further a towing cover T in shape integrated an intermediate carrier, on which the dust filter bag 8 sits. Such an intermediate carrier T is from German Patent Application 39 11 580 of Applicant known. It is full content in this regard referred to this document.

The drag cover T has a housing cross-section adapted plan, emerges from the mantle wall of the Housing 2, however, back, so that it in the from Figure 1 apparent coaxial position of the motor housing 6 and Chamber 7 substantially completely removed from view is. The towing cover T is also foldable, the towing cover T also hinged side, as well as the filter frame 13, two bearing eyes formed. Here, the towing lid T works around the same Folding axis 14 as the chamber. 7

The immediately following the towing lid T Dust filter bag 8 has a holding plate 16 trained soil. His general outline corresponds also the cross-sectional shape of the filter frame 13, which for supporting support of the holding plate 16 on the inner wall edge steps 17 forms. This can the holding plate 16 in the Aufklappstellung of the device do not slip into the chamber 7. The common Folding axis 14 of filter frame 13 and trailing cover T extends approximately at the level of Auflagerandstufe 17 the filter bag holding plate 16.

With the housing 2 closed, that is in the operating position of the vacuum cleaner 1, projects the fan-air duct of the Motor blower with a stepped, cylindrical Mouth end in the lower portion 18 'of a suction 18. The latter is above the top of the towing cover T before, wherein the suction port 18 the Schleppdekkel T is the same shape and where the suction 18, a cross-sectional corresponding opening 19 of the filter bag holding plate 16 enforcing, border closing protrudes into the interior of the dust filter bag 8.

The suction nozzle 18 tapers to its free end out, so that its insertion into the opening 19 practically has centering effect.

To remove the dust filter bag 8, the chamber is the 7th with the towing cover T after loosening a housing-side Lock assurance in the illustrated in Figure 3 Open position pivoted. To now the dust filter bag 8 to release to release, the Schleppdekkel T folded away from the chamber 7, including a handle 20 on the suction port 18 facing away from the top Tow plate T is provided. This handle 20 is via a film hinge at the top of the towing lid T arranged hinged.

In accordance with at the operating position of the vacuum cleaner Figure 1, due to the falling position of the dust filter bag 8, a falling back of suction material in the area of the motor housing 6 to avoid, on the free end of the suction nozzle 18 is formed a valve flap be.

At the bottom, i. at the suction nozzle 18 facing Side of the towing lid T, this is one pivotable plate 21 for holding an actuating projection B assigned. This plate 21 is over a Hinge 22 at the free end of the towing cover T arranged pivotally. The plate 21 extends from the hinge 22 starting to about the middle of the Trailing cover T under the suction nozzle 18. For this purpose, the plate 21 has a slot-like Breakthrough 23. The hinge 22 facing away from the area the plate 21 is tapered. In this area is a rectangular receiving chamber in cross-section 24 positively arranged, which over the End portion of the plate 21 protrudes. In this recording room 24, the operating projection B is freely displaceable stored, wherein the actuating projection B in the essentially of a rectangular cross-section Actuating arm 25 and one at the free end of this Actuating arm 25, i. the receiving chamber 24th turned away end formed actuating lug 26 composed. The actuating lug 26 has in the position according to FIG. 3 in the direction of the dust filter bag 8.

The operating projection B is in its extension direction spring-trained. This is served in the Receiving chamber 24 arranged compression spring 27, which one on the in the receiving chamber 24 protruding End of the actuating arm 25 arranged pin 28th includes. At the other end, the compression spring 27 is supported an end wall 29 of the receiving chamber 24 from. Latter is closed with a lid 30, which is clamping the end wall 29 and the side walls of the receiving chamber 24 includes. In the open end area, i. in that area, in which the actuating arm 25 in the receiving chamber 24 protrudes, the lid 30 has a after inside projecting support collar 31. The latter serves as Stop limit for by the compression spring 27 in Outward direction loaded actuator arm 25, which a corresponding, corresponding support edge 32 has.

The plate 21 and the actuation projection carried thereby B are against a spring 33 around the hinge 22 swiveling. This spring 33 extends here between the underside of the towing lid T and the this underside associated side of the plate 21st For this purpose, at the bottom of the towing cover T a corresponding recess 34 for receiving the one End of the spring 33 is formed. The other end of the Spring 33 includes a circular projection 35 of Plate 21 in the region of the transition from the plate 21 to the receiving chamber 24. The spring 33 loads the plate 21 and the associated with this operating projection B always in the direction of the dust filter bag 8. Der Verschwenkweg the plate 21 is limited such that in a swinging away of the towing lid T of the Dust filter bag 8 or from its support plate 16 away the plate 21 with the edge of the in the area of Breakthrough 23 protruding projection 35 at one outer edge side collar 36 of the suction nozzle 18 is supported (See Figure 12). The spring 33 is how next already described in detail above, in particular also of importance for further implementation and in particular completion of the closure movement in a Opening the vacuum cleaner.

The dust filter bag 8 is essentially made the already mentioned holding plate 16 and one at the Underside of this holding plate 16, for example, adhesively bonded, preferably made of paper Dust bag 37 together.

The holding plate 16 has almost the inside the filter frame 13 corresponding contour and sets It consists of four layers of cardboard-paper material stacked on top of each other together. These layers 38 to 41 are glued together. The retaining plate 16 thus formed is supported in the inserted state of the dust filter bag 8 at the edge steps 17 of the filter frame 13 from. Around a sagging of the dust filter bag 8 in the operating position of the vacuum cleaner 1 according to FIG. 1, Locking devices 42 are provided, which at the Inside the filter frame 13 are arranged and on the top of the support plate 16 act. The dust filter bag 8 is thus in the region of its holding plate 16th locked.

For positionally correct, secure assignment of the dust filter bag 8, the holding plate 16 in the area both Narrow-side orientation features 43 in matching Counter features 44 of the inner wall of the filter frame 13 intervene. Regarding the orientation features are trapezoidal projections on the Narrow side of the holding plate 16 forming plate-shaped Body. How to achieve an alignment-oriented Position between opening 19 and suction 18th

At the longer side margins, the holding plate 16 gripping openings 45. Both gripping openings 45 are Beveled and the corresponding inner wall of the Filter frame 13 open. In the open position of the Housing 2 and after pivoting the towing cover T can be retracted by cocking grip of the wasp-waisted Center zone of the holding plate 16 of the dust filter bag 8 comfortably detected and excavated from the chamber 7.

As already mentioned, the holding plate 16 is made four layered layers 38 to 41 together, wherein the underside of the bottom layer 41 of the Paper dust bag 37 is glued. This lowest Lage 41 has a circular breakthrough 46th Die over this layer 41 arranged layer 40 is contours and coextensive as the layer 41 is formed and has also arranged coaxially with the opening 46 Breakthrough 47 on, which also has the same radius as the breakthrough 46 has.

The layer 39 arranged above the layer 40 is in the form of a spacer layer for the ceiling forming layer 38 is formed and serves to form a free space 48. FIG. 10 shows a plan view of the situation 39 with omission the lying above this layer 39, forming the ceiling Lage 38. The situation 39 is essentially as a same outer contour as the other three layers having Edge strips formed. Specifically, this is solved that in the region of the opening 47 of the layer 40th edge outer side layer portions 49 to 51 arranged are, which from the respective outer edge to the Near breakthrough 47 extend, leaving a distance between the aperture 47 and the Inner edge of the respective ply strip. The Andes Longitudinal sides of the retaining plate 16 arranged layer strips 49 and 51 are at the breakthrough 47 facing End face connected to the ply strip 50 and extend starting from this starting in the area the gripping openings 45, which gripping openings 45 through corresponding recesses in the layers 38, 40 and 41st are formed. The distance between the two edge edges the ply strips 49 and 51 is larger here chosen as the distance between the facing ones Edge edges of the gripping openings 45. On the Layer strips 49 and 51 opposite side of Gripping openings 45 put the ply strips as Layer strip sections 49 'and 51' while maintaining the same width away. Keeping a distance to the gripping openings 45, the ply strip portions thicken 49 'and 51' in such a way that they, from Outgoing edge of the holding plate 16, starting in the middle area of the holding plate 16, leaving a slot 52 extend. These widened Regions of the layer 39, which consequently in the the Breakthrough 47 opposite end portion of the holding plate 16 are arranged, are denoted by the reference numerals 53 and 54. In the transition area between the position strip portions 49 'and 51' and the regions, respectively 53 and 54 are thus in the longitudinal extension of Holding plate 16 acting stops 55 formed.

The uppermost layer 38 forming the ceiling has a contours and almost the same area of education on as the layers 40 and 41. Again, is coaxial with the apertures 46 and 47, an opening 56 is provided. These openings 46, 47 and 56 form the already mentioned opening 19 of the holding plate 16. The top Layer 38 is further with one above the slot 52 arranged the situation 39, open-edge and almost the same width as the slot 52 having recess 57 provided. This recess 57 extends from the opening 19 opposite narrow side the holding plate 16, starting in the direction of the longitudinal extent the holding plate 16 to about the middle the latter.

Between the two lower layers 40 and 41 is a Rubber seal 58 inserted and preferably glued. This rubber seal 58 is in the region of the openings 46 and 47 arranged and has a circular opening 59, which is formed smaller diameter than the apertures 46 and 47. The opening 59 of the rubber seal 58 is coaxial with the apertures 46 and 47 aligned. The rubber seal 58 is used in by the opening 59 passing and into the interior of the dust filter bag 8 projecting suction 18 for sealing Termination between the dust filter bag 8 and the suction nozzle 18.

In between the layers 38 and 40 formed and by the ply strips of the layer 39 limited space 48 is a closure element V slidably mounted (See Figure 10). The closure element V has in this case essentially a spade-shaped plan, a spade stem 60 in the one shown in FIG Position in the slot 52 of the layer 39 rests. The with the spade stem 60 connected closure plate 61st has a nearly the distance between the edge inside pages the ply strips 49 and 51 and the ply strip sections 49 'and 51' corresponding width on and extends in the position shown in FIG 10 of the Stops 55 of the layer 39, starting up to the edge of the Breakthrough 47 of the situation 40 or up to the edge of the Opening 19.

The spade stem 60 of the closure element V is in this case in the recess provided in the uppermost layer 38 57 free and serves as an operating section. For this the spade stem 60 has a manipulation projection M in the form of a kink 62. This results in the free end of the spade stem 60 a ausknickbarer Section 63.

It is also conceivable, the manipulation projection M so form, that at the free end of the spade stem 61 is arranged a thickened area. Alternatively, can also in this area a Recess in the form of a longitudinal slot or the like be provided.

Due to this configuration of the holding plate sixteenth it is now possible, the opening 19 by means of Closing element V either to close or to to open. Here is the closure element V in the area the free space 48 of the layer 39 is longitudinally displaced, wherein the closure element V in both the closure and Open position as well as in any intermediate position in the Outer contour of the holding plate 16 completely absorbed is. This means that neither at the closure nor in the open position, parts of the closure element V beyond the outer contour of the support plate 16 protrude. This is also in the illustrated embodiment not possible because of the shape and size of the filter frame 13 of the vacuum cleaner 1 no enlargement of the outer contour the holding plate 16 would allow.

The displacement of the closure element V is performed by Grasping or attacking the manipulation projection M, which in the region of the recess 57 of the uppermost Location 38 is exposed for attack. This recess 57 is here in the longitudinal extension of the displacement the closure element V adapted. By moving the closure element V from the open position according to Figure 10 in a closed position in the direction of Arrows y is the opening 19 of the holding plate 16 by means closed the closure plate 61. The closure element V is in this case by the ply strips 49 and 51 led sideways. The end position of the closure position is reached when the front side of the closure plate 61 to the inner peripheral edge of the front side Layer strip 50 abuts.

The open position is due to the already mentioned stop the closure plate 61 to the stops 55 of the Location 39 defined.

To remove one with such a holding plate sixteenth provided dust filter bag 8 from the chamber 7 is this initially together with the towing lid T off the operating position according to Figure 1 in a removal position pivoted according to FIG. As from this presentation to recognize this lies with the actuating projection B provided, pivotable plate 21 in parallel Position to the towing cover T between the latter and the holding plate 16. The operating lug 26 of the actuating projection B engages behind the auszubickbaren Section 63 of the spade stem 60 of the closure element V. Hereinafter, the towing cover T by means of Handle 20 swung from the chamber 7, so causes the attacking on the ausfinkbaren section 63 Actuator 26 a displacement of the closure element V in the closed position of the opening 19. In the train pivoted the pivoting of the towing cover T. at the same time the plate 21 with the actuating projection B about the hinge 22, due to the spring 33, such that the Abknickbare section 63 of the closure element V at least over a large part of the Verschwenkweges of the towing cover T always from the operating lug 26 is applied. There is one here scissors-like opening between the towing lid T and the plate provided with the operation projection B 21. Due to the fact that the actuating arm 25 resilient is stored in the receiving chamber 24, this can according to the course of movement in the receiving chamber Dodge 24. The resilient support of the actuating projection B and the resilient Ver-swiveling the Plate 21 and associated with this operating projection B always ensure the rear grip of the Actuation nose 26 behind the auskickable section 63 over the entire displacement of the closure element V. Once the closure element V, the closure position the opening 19 is supported, as already mentioned, the front edge of the closure element V or the closure plate 61 at the inner peripheral edge of the ply strip 50 of the layer 39 from. In this position also reaches the kink 62 of the spade handle 60, the front edge 64 of the recess 57 of the uppermost Position 38. The actuating projection B is in this position continue to strive, the closure element V in further To shift direction of the arrow y. The operating nose 26 still engages behind the ausknickbaren Section 63 of the spade stem 60. In the course of further Swiveling the towing lid T from the chamber 7 fort now takes a grip under the operating lug 26 under the buckling section 63, which, conditioned by this and by the still prevailing Actuation in the direction of the arrow y, upwards towards, i. through the recess 57 of the uppermost layer 38th stepping out, buckling. This turns out to be one second kink point 65 (see Figure 11). Here shows itself that the spade stem 60 width as the recess 57 may be formed, if necessary also even narrower than this, because otherwise of the operating nose 26 acted upon or underrun area do not dodge in the position shown in Figure 11 can. This would lead to destruction of the closure element V in the area of the attack surface of the actuating nose 26 lead. As far as the shift of the Closure element and the action on the spade handle 60 is not realized via a bend, but only by one on the Spatenstiel bspw. applied manipulation projection M, it is too possible and is preferred that the spade stem 60 with a larger width than the recess 57 is formed is, so that the edges of the recess of the spade handle are under attack.

In the course of the further pivoting of the towing lid T in a position releasing the dust filter bag 8 according to Figure 12 passes over the actuating projection B with the actuating lug 26 the buckling section 63, with the latter, the recess 57 of the uppermost layer 38 passing through, being raised. The actuating projection B reaches a predefined end position, by, as already described, in the breakthrough 23 of the plate 21 protruding projection 35 itself arranged on the outer edge side of the suction nozzle 18 Collar 36 is supported. The towing lid T can too even further than in the 90 ° position shown in Figure 12 be pivoted so that the dust filter bag. 8 can be easily removed from the chamber 7.

To remove the dust filter bag 8 this is in Area of the gripping openings 45 of the holding plate 16 gripped and against the locking action of the locking devices 42 of the filter frame 13 pulled out of the chamber 7.

However, if such a sealed dust filter bag 8 continue to be used, it is opened the opening 19 in the simplest way. For this purpose, the Tow cover T back towards the chamber 7 ver-pivots, whereby the actuating projection B with the free end portion of the actuating arm 25 at the End edge 64 of the recess 57 of the holding plate sixteenth applied kink point 62 applied. In the course of the further pivoting of the towing lid T in the Closed position displaces the actuating projection B the closure element V in an open position of the opening 19, by the actuating arm 25, the closure element V in the area of his spade stem 60 in front of him pushes. As mentioned earlier, is in this context, in particular, the Längenveränderbarkeit of the actuating projection B against the Compression spring 27 of importance. Namely, then, if due an unfortunate angular position when Impact of the actuating projection B on the spade handle 60 would set itself a blockage. Instead, initially shortens the length of the actuating arm 25, whereby also the angle of influence changed to the spade stem 60, so that an optionally resulting self-locking or blocking can be overcome. In the further course of the pivoting movement the towing lid T also closes the scissors-like arrangement of towing lid T to the Plate 21 and the actuating projection arranged thereon B. After complete opening of the opening 19 of the Holding plate 16, with corresponding edges of the Closure plate 61 on the stops 55 of the layer 39th supported, the actuating projection B passes over in Area of the free end of the actuating arm 25 the bendable section 63 and sits down with his Actuator 26 in turn behind this section 63rd It is also important that the actuating projection 26 against a housing-fixed stop 26 'moves (See, for example, Fig. 3). This is preferably done under a certain noise, which the User a proper opening state of the Filter bag and a total of functionally flawless Operational readiness of the vacuum cleaner signals.

The illustrated and described dust filter bag 8 is with its support plate 16 in vacuum cleaners. 1 can be used, which no device for automatic Close or open in the course of opening or closing of the vacuum cleaner. Here is now also the possibility of the closure element V by hand to relocate in the respective position by the abknickbare Section 63 is seized by hand and thus a displacement of the closure element V done can. In addition, there is still the possibility that Closing element V in the region of the gripping openings 45 to capture by using the staple grip between the Layers 38 and 40 in this area exposed closure element V is seized and relocated. This also works in the specific example as it is in the embodiment is shown, in which the closure element only up to the edge of the contour of the retaining plate 16 extends in the region of the gripping openings 45 and does not protrude beyond this contour.

When using a vacuum cleaner 1, with a like illustrated and described actuating projection B is also a use of conventional Dust filter bags, i. Dust filter bags without closure element V, conceivable. Here would be a panning of the towing cover T in an open or Closure position of the actuating projection B on the Retaining plate 16 run away without any Functions would be performed.

Finally, it is also possible to use the plate 21 of the Tow cover T with registration tabs to provide. These registration projections move after pivoting of the actuating projection B in corresponding Registration openings, which in the embodiment shown the gripping openings 45 of the holding plate sixteenth can be one. Here, the education is taken that a closing of the vacuum cleaner 1 only in the registration openings or gripping openings 45 retracted Registration tabs is possible. This device should serve to close the vacuum cleaner 1 only possible with the dust filter bag 8 inserted is. Is a dust filter bag 8 inserted into the chamber 7, so the actuating projection B pivots, as already described in the course of the closing movement in Direction to the underside of the towing lid T, which also moves the registration tabs accordingly in the closing position of the Chamber 7 to the towing lid T in the appropriate Registration openings or gripping openings 45 occur can. However, if no dust filter bag 8 is inserted, so the operating projection B does not find an abutment for pivoting, whereby the registration tabs in remain in their locked position. In this locked position These are based on the closing movement of the Towing lid T, for example, on the outer edge of the Filter frame 13 from, bringing a closing of the vacuum cleaner 1 counteracted. Will be different now large registration tabs according to different associated with large registration holes, so is also a correct insertion of the dust filter bag 8 ensured in the chamber 7.

Shown and described, first with reference to Fig. 14 in a second embodiment, a Holding plate 101 of a dust filter bag. The holding plate 101 is, as shown in Fig. 15, a total of four layers (Fig. 15 is a greatly enlarged Presentation). An upper layer 102 has a circular Opening 103 with an opening edge 104. Next is in the upper layer 102 a wider slot 105 educated. Under the top layer 102 is a slidable Closing element V arranged. The closure element V is at its style end with an essay 106, which in the embodiment also consists of a poplar layer provided. The essay 106 protrudes into the slot opening 105. By means of this Aufsatzes 106 is the shutter V by hand or automatically movable.

The shutter V is shown in FIG External dimensions by the dot-dash line indicated. The opening 107 of the middle layer 108, i.e. the third layer from the top of the holding plate 101, is formed larger than the - upper - opening 103 or the lower opening 109 (see Fig. 15). Between the Layer 108 and the lowermost layer 110 of the holding plate 101 a rubber seal 111 is taken. For example the rubber seal 111 by gluing between the Layers 108 and 110 secured. The rubber seal 111 extends annularly from the opening edge 104 inside and has an inner opening edge 112th

Formed to the middle layer 108, i. the third Top position of the holding plate 101 is a stabilizing part in the form of a tongue 113. The tongue 113 is on from an end edge 114 of the closure element V farthest place (relative to the withdrawn position as shown in FIG. 14) of the opening 103 formed.

By the Anformung of the tongue 113 to the position 108 of Holding plate 101 shows that this in the embodiment also from a paperboard paper material exists, as well as the other layers of the holding plate.

The tongue 113 has an extension e, starting from the opening edge 104 in the interior of the opening 103, which is about half of the extension E of the rubber seal 111 from the opening edge 104 in the interior of Opening 103 corresponds. In the embodiment amounts a diameter d of the circular opening 103 about 5 cm. The extension e corresponds to about 1/10 of this Diameter, so about 5 mm, whereas the Rubber seal 111 about 1 cm in the inside of the opening 103 extends (dimension E).

The sectional view of Fig. 16 shows a section in the plane between the layers 115 - the second layer from above - and the situation 108. To indicate that this Layers are glued together and are therefore connected, is the cutting plane, as far as the Bonding coincides, in hatched representation played.

It can be seen that the tongue 113 immediately on the layer 115 is formed. Between the situation 115 and the layer 108, the rubber seal 111 is taken, wherein the outer edge of which runs only partially circular.

From the illustrations of Figs. 17 and 18 is the behavior the tongue 113 and the action of the tongue 113 in the operating state of the vacuum cleaner.

It is in detail a vacuum cleaner with a so-called drag cover 116, to which a Suction tube 117 is formed. To the characteristics of the Vacuum cleaner in detail, for example, on the EP A 25 32 057 referenced.

The suction tube 117 passes through the openings 103 and 109 and the openings of the intermediate layers the holding plate 111. The dimensions of the openings and in particular the dimension of the tongue 113 is on the diameter the suction tube 117 tuned such that a Kinking of the tongue 113 in the interior of the dust bag results. The seal 111, however, overhangs the tongue 113 completely - and protrudes radially inwards beyond - And lies fully on the suction tube 117 at. When pulling out the suction tube 117 from the Holding plate 101 of the dust filter bag remains due the occurred kinking of the tongue 113 a certain Preload to the inside and a corresponding action the tongue 113 on the rubber seal 111. This has As a result, that the rubber seal 111 in any case not up toward the opening 103 too extends and thus the closure element V readily can be closed. In the locked state is running the closure element V on top of the tongue 113 on - Based approximately on a representation of FIG. 15 -.

With reference to FIGS. 19 and 20 is in cross section, partially, a receptacle 118 for a dust filter bag shown. Regarding the dust filter bag is in particular in cross-section, a holding plate 101 to recognize as previously described.

The vacuum cleaner or the receptacle 118 has a closure plate 119, with the previously mentioned suction tube 117. Next is an actuating projection 120 to recognize who has a nose 121 with which he acting on the closure element V of the dust filter bag. The operating projection 120 is in a receptacle 122 linearly displaceable against the force of a spring 123. Further, the shutter 120 is over a band 124 - directly - connected to the closure plate 119. Specifically, the tether 125 of the tape 124 on the closure plate 119 at the bottom, formed near a pivot 126.

In the position shown in Fig. 19, in which the operating slide 120 only on the holding plate 111 of the dust filter bag is the tape 124 in a relaxed position. It still owns a certain amount of stock that can be exploited.

In the position shown in Fig. 20 is a rotational movement the closure plate 119 has been introduced, so that these about the axis of the joint 126 on the holding plate 111 of the dust filter bag pivots out. at This movement initially remains the relative position of the Actuating projection 120 relative to the holding plate 111 unchanged. The actuating projection 120 moves just against the spring force of the spring 123 something in the actuating projection 122 a. This movement can continue until the belt 124 tightened is. This streamlining occurs rather than the max. Einfahrvermögen of the actuating projection 120 in the receptacle 122 is used. As soon as the volume 124 tightened is, occurs by a further rotation of the shutter plate 119 about the axis of the joint 126 as it were Pulling away the actuating projection 120, so that this - by means of the recording 122 - to its articulation 127 around the closure plate 119 on the - bottom - The closure plate 119 to be pivoted. This is a further pressure build-up of the actuating projection 120 on the holding plate 111 of the dust filter bag counteracted.

Moreover, to the general embodiment of Recording and the closure plate and the actuating projection also on the unpublished documents German Patent Application 43 41 248 referenced.

Alternatively - but not shown in detail is - can also on the actuating projection 120 laterally, d. H. formed perpendicular to the plane supports be. These supports can, for example, on the - inner edge 128 of the receptacle 118 for the dust filter bag come to the edition. By a suitable vote between the total length of the actuating projection 120 and the arrangement of the supports can be achieved be that the actuating projection 120 with his nose 121 while on the holding plate 111 of the dust filter bag comes to the condition that, however, in the described Pivoting the closure plate 119 the resulting increased force in the course of - linear - compression of the Actuating projection 120 through the support edge 128th is recorded. The receiving edge 128 or the supports, formed laterally on the actuating projection 120 can then be further developed in detail be that they are under as little friction as possible slide on each other.

In a further embodiment is described in Type a closure plate 219 with suction 217th via a pivot 226 opposite a vacuum cleaner housing 202 mounted pivotally. An actuation advantage 220 on a plate 221 is over a hinge 222 at the free end of the closure plate 219 pivotally arranged. On the axis 227 of the hinge 222 a spreading spring 233 is arranged, which extends over a loop 234 on the underside 237 of the closure plate 219 supported, whereby the circular ring form of the Saugstutzens 217 adapted encloses this. By the Force of the spreading spring 233 are open shutter plate 219 these and the plate 221 slightly V-shaped held. The opening angle of this V-shape is by striking an L-shaped nose 224, the at a slot-like opening 223 for the Connecting piece 217 adjoins, bounded against this connecting piece 217, see. Fig. 27.

The suction nozzle 217 is connected to a valve flap 205 its free end, which is a falling back of Suction due to the falling position of the dust filter bag 208 in operating position, prevented. It deals this is a rib-reinforced membrane, which is simply riveted to a mandrel 218.

The pivotable on the underside 237 of the closure plate 219 attached plate 221 carries the against the Force of two springs 228, 229 slidably mounted Actuating projection 220. In the extended position The outline of the plate 221 fits with the extension Actuating projection 220 about the outline shape of the closure plate 219 and the closure plate 219 and plate 221 receiving the inside of the filter frame 213 at. That is, the operating arm 225 has approximately the same width as the plate 221. At his free End carries the actuator arm 225, slightly off-center offset, an actuating nose 216, which in the beginning described type a closure element V a Holding plate 201 of the dust filter bag 208 entrains.

Referring to Figs. 21 to 26, the mounting of the operating projection 220 explained in more detail on the plate 221. The plate 221 has perpendicular projecting, the actuating projection 220 laterally enclosing legs 230, 231 on, which at its free end on the axis 227 opposite side by means of a bolt 232nd are connected. Between the bottom 235 of the plate 221 and the latch 232 is the actuating arm 225 of the Actuating projection 220 out. A locking nose 236 beats when relaxing the springs 228, 229 to the latch 232 and prevents its withdrawal. The feathers 228, 229 are formed in cross-section U-shaped Channels 238, 239 held the actuating projection. The free leg ends of the channels 237, 238 are located on the bottom 235 on. For a better leadership of the operating projection protrude from the free ones Legs 230, 231 of the plate 221 projections 240, 241st from, so that the channels 238, 239 between these projections and the bottom 235 are held. In longitudinal extension each channel 238, 239 is one at a time Wall closed, on which the springs 228, 229 support. The opposite longitudinal end is open and there, the springs 228, 229 are based on plate-resistant Counter bearings 242, 243 from. When closing the dust filter bag 8, the operating projection 220 becomes first against the force of the springs 228, 229 in the direction postponed to breakthrough 223. It lies the Breakthrough 223 between the channels 238, 239 and can the actuating arms 225 connecting the channels 238, 239 for a rounding 244 have. To limit the Displacement of the actuating projection 220 on the Breakthrough 223 are on the wall 245 of the nose 224th Plates 246 provided on the front of the Fillet 244 of the actuating projection 220 impinges.

The holding plate 201 with the closure element V is in essentially according to the previous embodiments educated. But here it is the spade handle 260 a manipulation projection in the form of an essay 261, cf. Fig. 28, with the ceiling forming the uppermost position of the holding plate 201 closes. The Width of essay 261 is slightly less than the width of the for the actuation of the closure element V necessary width of the slot in the top Position of the holding plate 201, see. See also Fig. 9. Against the top of the spade stem 260 and the longitudinal side of the attachment 261 formed angular space is the operating lug 216 of the actuating projection 220 in the direction of motion, so finding an abutment. Alternatively to the essay could also be a recess be provided.

When swinging the closure plate 219 of the in Fig. 27 position shown in the position shown in FIG. 28 sets the plate 221 and the actuating projection 220 on the bottom 237 of the closure plate 219 at. Is missing the holding plate 201 and thus remains the V position between the shutter plate 219 and the plate 221 or the actuating projection 220, can be do not close the closure plate 219. Registration projections 203, 204 on the plate 221, formed by a widening towards the free end of the plate 221 and the actuating projection 220, drive at maximum pivoting in registration pictures 206 of on the filter frame 213 inwardly projecting recordings 207. Even so, closing the vacuum cleaner is only possible with inserted filter bag 208 possible.

In closed condition, cf. Figs. 28, 29 is the Closing plate 219 thereby locked by locking lugs 209 penetrate breakthroughs 210 in the closure plate 219. The locking lugs 209 can from a sealing edge 212 protrude, at least over the longitudinal extent of the filter frame 213 freestanding on an angle 211 the filter frame 213 is arranged. Against the smooth Inside the sealing edge 212 comes in a closed Condition one on the outside of the closure plate 219 circumferential sealing lip 214 in sealing contact. Also in this embodiment, as already described, a connection of the actuating projection 220th to the closure plate 219, z. B. by a limp Tying means take place in the course of a compression the actuating projection 220 at the same time a Pivoting the actuating projection 220 to initiate.
