00001 dust filter bag for a vacuum cleaner

00002

The invention relates to a dust filter bag for one

00004 Vacuum cleaner, with one made of a cardboard paper material

00005 existing holding plate with which a dust bag

00006 is glued, for example, which holding plate

00007 a sealable opening for an exhaust pipe

00008 of a vacuum cleaner, the opening having a

00009 separate closure element is closable from

00010 leave an open position in a closed position

Is producible, the closure element between two

00012 layers is displaceable. 00013

Such a dust filter bag is from DE-OS 2 407

00015 478 known. Here is a dust filter bag shown

00016 whose opening for a suction pipe of a vacuum cleaner

00017 closable by means of a foldable paper strip

Is 00018. This foldable paper strip is between two

Layers made of cardboard arranged such that a

00020 end of the paper strip in the area of a fold on the

00021 fixed lower position, for example glued

Is 00022. The other, free end of the paper strip protrudes

00023 beyond the contour of the layers to form a

00024 touch areas. The two layers have circular openings

00025 gen for the suction pipe of the vacuum cleaner. The paper-

00026 stripe also has a circular opening,

00027 which in the open position of the dust filter bag axially

00028 the openings of the fixed layers is aligned. To the

00029 Closing the opening of the dust filter bag pulls the 00030-free end of the paper strip outwards, where

00031 is partially stretched through the folded strips. The

00032 opening of the paper strip leaves the area

00033 of the openings of the two fixed layers, whereby the opening

00034 the dust filter bag is closed. It is

00035 there is no design-related possibility 00036 an already closed dust filter bag again

Open 00037 by moving the paper strip back.

00038 To remove such a dust filter bag after an

00039 wanted to continue closing the opening to use

00040 here is only the possibility of destroying the

00041 paper strip in the area of the openings of the two

00042 fixed layers. Furthermore, there is a holding plate with an opening which can be closed by a seal

00044 provided dust filter bag from US Pat. No. 2,864,462

00045 known. Here is also a sealing strip between

00046 see two fixed layers arranged, being at the bottom

00047 fixed position of the dust bag is attached. The closure-

00048 stripe extends lengthwise over the entire length

00049 Length of the two layers. In the open position for

00050 the suction pipe of a vacuum cleaner is the openings of the

00051 two fixed positions in the axial direction in the closure

00052 strips assigned another opening. For locking

00053 opening of the suction pipe is in the upper

00054 location provided an open edge through which

00055 the closure strip is within reach. Should the opening for

00056 the suction tube of the dust filter bag can be closed

00057, the fastener strip is on its in the

Gripped recess of the uppermost layer projecting area

00059 and then so far from the area between the two

00060 fixed layers until the opening of the sealing strip

00061 fens leaves the area of the two fixed layers. 00062

In the two aforementioned known solutions, the protrudes

00064 sealing strip in the closed position of the filter bag

00065 means beyond the contour of the respective holding plate. 00066

The object of the present invention is to provide a gate

00068 dust filter bag according to the invention for a vacuum cleaner

00069 cheaper to handle. 00070 00071 This problem is solved by the main claim

00072 specified invention. 00073

00074 The subclaims represent advantageous developments

00075. 00076

00077 Due to this configuration, a dust filter bag is

00078 tel created for a vacuum cleaner, the opening in

00079 area of a holding plate for a suction pipe of a dust

00080 suction device by means of a closure element

00081 locks can also be opened, the

00082 final element in both end positions, but also in

00083 each intermediate position does not have the outer edges of the

00084 holding plate protrudes. This is solved by the fact that the

00085 closing element in the closed position and in the open

Practical position in an outer contour of the holding plate

00087 is completely included and that the closure element

00088 in a separate from the opening of the

00089 top layer is exposed, with a longitudinal extension of the

00090 recess on a displacement path of the closure element

00091 is adjusted. It is also preferred that at least

00092 three fixed cardboard-paper material layers of

00093 holding plate one layer a support for the closure

Forms element in the open position. The locking element

00095 ment is designed so that this both

00096 in the closed and in the open position in the

00097 outer contour of the holding plate is completely included.

00098 This is solved, for example, by the fact that the

00099 closing element adapted to the opening of the holding plate

00100 has a closure surface with a handle arranged thereon,

00101 which closure surface for the production of the closure

00102 in the area of the opening of the holding plate

00103 device. The minimum displacement distance corresponds to

00104 at the diameter of the opening of the holding plate. Around

00105 an accidentally closed dust filter bag 00106 to open again, the closure element is so

00107 pushed the closure surface over the area of the opening

00108 leaves the holding plate at least to such an extent that the

00109 suction pipe of the vacuum cleaner can be inserted. The

00110 size of the closure element is chosen so that

00111 the displacement movements within the outer contour of the

00112 holding plate. Safe guidance of the locking

00113 element is hereby ensured that at

00114 at least three fixed cardboard-paper material layers

00115 a layer a substantially fully

00116 forms a flat support for the closure element. In

00117 a preferred embodiment is the arrangement

00118 met that the full-surface support of the closure

00119 element in both the open and the closed

00120 position is formed. Deviating from the full area

00121 A contoured support can also be provided.

00122 hen, which can be recommended with a view to reducing friction. To improve handling

To reach 00124 of the closure element, the closure

00125 element in a recess separate from the opening

00126 the top layer free, with a longitudinal extension of the

00127 recess on a displacement path of the closure element

00128 is adjusted. The in the separate recess of the

00129 top layer exposed area of the closure element

00130 tes serves as a handle. This area can

00131 both taken by hand and mechanically in the course

00132 to open or close the vacuum cleaner

00133 be struck. Preferably, the formation of the

00134 Closing element possessing holding plate selected

00135 be that the latter consists of three solid layers, wherein

00136 the middle layer has a recess for receiving the

00137 has final element. The width of the recess

00138 corresponds to the width of the closure element.

00139 The length of the recess, however, results from the

00140 length of the closure element plus the displacement path, 00141 which is at least the diameter of the

00142 corresponds to the opening. The middle, the locking element

00143 ment receiving layer can thus as one every four sides

00144 th closing frame can be formed. The lowest position

00145 forms a full-surface support for the

00146 closure element. Around the opening of the holding plate

00147 to close the inlet of the suction tube is sealed at

00148 of the preferred embodiment, a further layer arranged below the lowest layer 00149 is provided between

00150 which two layers a seal in the area of the opening

00151 voltage lies. It is therefore a closable dust filter

00152 created for a vacuum cleaner that handles

00153 is technically optimized. The closure element is

00154 in the closed and in the open position in the outer

00155 contour of the holding plate completely included. Neither in

00156 the two end positions still in an intermediate position

00157 project parts of the closure element over the outer

00158 contour of the holding plate. Different vacuum cleaners

00159 offer in the area of the holding plate of the dust

00160 filter bag no space to enter a

00161 the outer contour of the holding plate projecting area

00162 of the closure element. The dust filter according to the invention

00163 bag can, however, be inserted into such a vacuum cleaner.

00164 sets and here mechanically in the course of opening

00165 or closing the vacuum cleaner closed or opened

00166 net. However, there is also the possibility of one

00167 manual control of the closure element by hand. In

An advantageous further development provides that

00169 at least on part of the displacement path of the

00170 closing element a closing element edge up to

00171 edge contour of the holding plate or beyond

00172 stretches. This configuration can, for example, in

00173 area of edge recesses of the holding plate for gripping

00174 fen the latter when removing the dust filter bag

00175 be formed from the vacuum cleaner. In the area of this 00176 edge recesses can the closure element edges themselves

00177 extend to the edge of the recess, with which at least

00178 least on part of the displacement the locking element

00179 ment also here, for example, by means of a clamp handle

00180 can be moved. There is also the possibility

00181 speed that the closure element edges over the edge

00182 contour extend in the area of the edge recess.

00183 In a first version, the locking elements extend

00184 margins very little, on the order of

00185 tenths of a millimeter, beyond the edge recess. In

00186 of a second version can also extend

00187 may be essential, for example a few millimeters or

00188 even move in the centimeter range. In particular

00189 if there is a separate sliding projection laterally

00190 is formed on the closure element, which also

00191 represents a possible alternative. Conditional on this

00192 configuration is another way of shifting

Given the closure element ben, if for example

00194 there is a mechanical defect. As already mentioned,

00195 is the closure element between two fixed layers

00196 stored, with a lateral guide through between

00197 webs arranged in the two fixed layers or the like

00198 chen is given. In the area of these webs

00199 further stops can be provided, which both

00200 open as well as the closed position of the sliding

Define 00201 element. This advantageously indicates

00202 closure element a substantially spade-shaped

00203 floor plan. The spade handle forms the actuating

00204 supply section for the closure element. Here is the

00205 lateral support of the closure thereby

00206 realizes that between two fixed layers another

00207 only a layer forming an edge is arranged, which

00208 before as a negative form of the spade-shaped closure element

00209 tes formed taking into account the displacement

00210 is. In the area of the transition from the spade handle to the 00211 end surface of the closure element are caused by

00212 the spade-shaped plan, stop edges formed,

00213 which against corresponding stop edges of the frame

00214 migen, the position forming the lateral support in open

00215 step into position. In the closed position, the

00216 spade handle opposite edge of the closure element

00217 mentes against a corresponding area of the edge

00218 forming location. To ensure optimal handling

00219 most, it is provided that the spade handle of the recess

00220 is assigned. As already mentioned, the longitudinal first

00221 stretching the recess to the displacement path of the

00222 final element adapted. Advantageously,

00223 in the recess at least the same width as

00224 the spade handle of the closure element. Alternative is

00225 it is also possible that the spade handle has a larger width

00226 as the recess. Moved on one or both sides

00227 the spade handle in this embodiment is

00228 reached for the edges of the recess. In the area of this

00229 recess can now be used as an actuating section

00230 trained spade handle gripped by hand or mecha-

00231 be moved niche. For this purpose, it can be provided that

00232 formed a manipulation projection the spade handle

00233 is. This can be at the free end of the spade handle

00234 arranged thickening or also in this area

00235 provided recess. In a preferred embodiment

00236 design, the manipulation lead is chosen so that

00237 the spade handle has a foldable section.

00238 This section can be easily done by hand

00239 can be gripped. It is also conceivable to have a mechanic in

00240 the area of the bendable section act

Let 00241. An education is preferred in which

00242 two kinks are formed. 00243

The invention further relates to a vacuum cleaner

00245 with a dust filter bag, the dust filter bag 00246 has a holding plate with an opening for one

00247 suction nozzle, wherein the holding plate is a closure element

00248, which in the course of opening the vacuum cleaner

00249 is automatically shiftable to a closed position. 00250

00251 Such an embodiment is also known from the

00252 already mentioned US Pat. No. 2,864,462. Here is the

00253 closable dust filter bag already mentioned

00254 inserted in the vacuum cleaner that an actuation

00255 jump of the vacuum cleaner in a recess of the free

00256 end of the closure element can engage. through

00257 this actuation projection becomes the closure element

00258 of the holding plate in the course of opening the vacuum cleaner

00259 automatically moved to a closed position. in this connection

00260 it is also known by means of the actuating projection

00261 when closing the vacuum cleaner on the closure element

00262 act so that a release of the opening of the

00263 Holding plate of the dust filter bag is done. 00264

00265 In an advantageous embodiment of the invention

00266 stand is provided that the actuating projection in

00267 its direction of extension is resilient.

00268 Due to this configuration, the actuation

00269 jump can also be used with such vacuum cleaners, which

00270 a narrow radius between the pivot axis of the

00271 dust filter bag carrying vacuum cleaner part and

00272 closure element of the other vacuum cleaner part on

00273 sen. With such tight radii, it is imperative

00274 that the actuating projection after engagement in the

00275 closing element or after its application in

00276 yields from the pivoting movement. By particular

00277 meaning is the resilience or resilience of the

00278 actuation projection also to prevent

00279 Self-locking or self-blocking. Even if the actuator

00280 projection lead once at an unfavorable angle 00281 should hit the dust filter bag can through the

00282 deflection a further pivoting of the actuation

00283 jump carrier (in the individual case of the drag cover, see

00284 below) and so the angle of attack between

00285 cleaning projection and dust filter bag are changed,

00286 so that there is no longer any self-locking. The moving

00287 availability or resilience is solved in detail so

00288 that the actuating projection changes in the course of the

00289 kens of the dust filter bag in the use position of the

00290 vacuum cleaner in its direction of extension accordingly

00291 can shorten. This resilient training of the actuator

00292 is also particularly advantageous

00293 if not appropriately adapted dust filter bag

00294 can be used. Especially when dust filter bags

00295 tel are used, which do not have a device for

00296 Have the opening for the suction nozzle closed.

In an advantageous development it is provided that

00298 the actuating projection on a drag cover

00299 det. Such a drag cover is particularly useful for

00300 vacuum cleaners with falling dust filter bags

00301 is an advantage. Here is to remove the dust filter

00302 prey the bag chamber together with the drag lid

00303 pivots. The actual opening then takes place

00304 the bag chamber by the drag cover in such a way

00305 is pivoted that the dust filter bag is released

00306 will. Here, the

00307 actuation projection formed the closure element of the

00308 holding plate of the dust filter bag such that the opening

00309 closed the holding plate for the suction nozzle

00310 will. After this, however, the reuse of this

00311 dust filter bag desired, so the drag lid

00312 pivoted again in the direction of the bag holder,

00313 the actuating projection in turn the locking element

00314 ment shifted such that the opening of the holding plate

00315 is released. However, it is 00316 bar, the actuating projection directly, ie under

00317 hung a drag cover to be attached to the vacuum cleaner

00318 NEN. Second-hand optimization is also

00319 ren given that the actuating projection against

00320 a spring is pivotable. The second feather (in the lower

00321 switched to the first spring against which the actuating

00322 protrusion can be shortened in length) essentially produces 00323 a locking force for a displacement of the locking

00324 element in the closed position. Especially at

00325 one opening of the vacuum cleaner bumps the second

00326 spring, in the further course of the opening movement, the

00327 actuation projection still forward and so causes

00328 at least the last part of the closing movement of the

00329 closure element. In addition to the resilient training

00330 fertilization of the actuating projection in the direction of extension

00331 it is also pivotable against a spring.

00332 forms. It is also provided that connected to the

00333 actuation projection registration projections provided

00334 which, after swiveling the actuator

00335 in the registration openings of the other

00336 Retract vacuum cleaner part, a closure of the

00337 vacuum cleaner only with retracted registration tabs

00338 is possible. This is to ensure that

00339 the vacuum cleaner should only be closed when the dust

00340 filter bag is made possible. Is not a dust filter bag

00341 inserted, the actuating projection does not find any

00342 corresponding support when closing the vacuum cleaner

00343 gers so that it does not move out of position

00344 device, with which the registration

00345 projections remain in their locked position. Now

00346 tries to close the vacuum cleaner, the regi

00347 strings protrusions against corresponding restricted areas of the

00348 other vacuum cleaner parts. When the dust filter

00349 bag, however, the actuating projection swivels in the

00350 train of closing the vacuum cleaner, which also the 00351 registration tabs are shifted so that they in

00352 the registration openings of the other vacuum cleaner part

00353 can retract and thus closing the vacuum cleaner

Allow 00354 gers. Advantageously,

00355 see that the registration tabs on one with the

00356 actuation projection formed firmly connected plate

00357 are. When using a dust filter bag in the

00358 already described type acts on the actuating

00359 jump of the vacuum cleaner the closure element in the area

00360 of his spade step designed as an operating section

00361 les. Is the spade handle of the closure element with

00362 provided a bendable section, so engages behind

00363 the actuation projection when opening the vacuum cleaner

00364 this foldable section and thus relocates it

00365 closure element in a closed position of the opening of the

00366 Holding plate of the dust filter bag. Should such

00367 sealed dust filter bag can still be used

00368 the actuating projection of the dust

00369 sucker in the course of closing the vacuum cleaner

00370 area of the ^' foldable section such that the

00371 closure element is moved to an open position.

00372 It goes without saying that it is also on insertion

00373 a dust filter bag opened in the usual way

00374 no disturbances in the function of the actuating projection

00375 total is coming. It is therefore irrelevant whether the dust filter

00376 bag in a closed or open state in

00377 the vacuum cleaner is used. When relocating the

00378 closure elements in the open position can be at a

00379 embodiment of the actuating projection a manipulation

00380 tion projection on the closure element, preferably

00381 over the spade handle of the closure element. Also

00382 after overflowing this locking projection is the

00383 stock length of the - somewhat sprung - actuation

00384 jump not fully extended. Rather,

00385 want the actuation projection under certain length 00386 gene shortening (deflection) against a housing-fixed

00387 stop after overflowing the manipulation projection

00388 is present. This is also important in that

00389 First open the suction nozzle of the vacuum cleaner

00390 opening of the filter bag can move out before then

00391 in the course of further opening or pivoting the

00392 actuating projection is also pivoted because

00393 borrowed the length reserve is fully exhausted by

00394 ren the telescopic length of the actuating projection

00395 sat. Only then is the opening of the dust filter bag

00396 slid shut, since now the opening is also free because

00397 the suction port is extended. Moreover, it follows

00398 when closing the vacuum cleaner due to the above-mentioned

00399 the manipulation lead through the actuator

00400 lead and the movement limitation of the actuation

00401 projection by resting on the housing-fixed

00402 head start a distinctive click sound that the user

00403 also signals that the vacuum cleaner is now full

00404 is ready for use. 00405

00406 The invention further relates to a dust filter bag

00407 of the type mentioned in the one on the edge

00408 the rubber seal protruding inwards from the opening edge

00409 is seen. Such a dust filter bag is for example

00410 as known from DE A 1 39 19 256. Next is to

00411 prior art also refer to DE A 1 24 07 478

00412 sen. In the dust filter known from DE A 1 39 19 256

00413 terbasche is in a sliding closure part

00414 likewise an opening is formed, whereby for use

00415 tongue of the dust bag the opening in the holding plate and

00416 the opening in the sliding closure part in a

00417 must be placed on top of each other. The opening in

00418 the sliding closure part has an annular

00419 shaped seal. With such a seal it can

00420 In the course of use, the effect that the sealing 00421 in some way sets up and a lock

00422 then the dust filter bag in the desired shape

00423 is no longer possible. The resulting pro

00424 blem to specify such a dust filter bag, at

00425 which ensures a complete closure

00426 is, first and foremost the subject

00427 of claim 14 solved, with the focus being

00428 that one overlaps with the rubber seal

00429 Stabilizing part protruding inwards

00430 is provided. A rubber seal as mentioned here 00431, whereby it is not the rubber material 00432 that matters, but this seal also from another

00433 can consist of elastomeric or comparable material,

00434 can when using such a dust filter bag

00435 through the retracted suction tube a certain

00436 experience deformation. In particular, is also often a

00437 observed deterioration in elastic properties.

00438 This is particularly the case when, as is often the case,

00439 the dust filter bag with retracted suction tube remains in this position for several weeks or months.

00441 When pulling out the suction tube it can then become a

00442 Turn the rubber seal that protrudes into the interior of the dust filter bag. This then blocks

00444 a complete closing of the opening. That invented

00445 stabilizing part provided in accordance with the invention now provides

00446 to ensure that this does not occur or the 00447 rubber seal each have a knockout in the direction of the

00448 interior of the dust filter bag (down) abandoned

00449 is. The stabilizing part can in particular also consist of

00450 the cardboard-paper material already mentioned

00451 hen. This occurs when the suction pipe is retracted

00452 also for kinking the stabilizing part. There

00453 but the stabilizing part due to its surface

00454 bility when pulling the suction pipe out of the opening

00455 can not fold over, remains even after a full 00456 constant removal of the suction tube from the opening

00457 an orientation of the rubber seal in the interior of the

00458 dust filter bag. The stabilization is suitably

00459 tion part attached to the location of the opening, which at

00460 a closure is the last to be run over by the closure element 00461. In addition, of course, you can too

00462 several such stabilizing parts can be provided

00463 or even a stabilizing ring rim, which is bent over a total of 00464 when the suction tube is retracted. It

00465 also advantageous if an extension of the stabilization

00466 tion part inward with respect to the opening edge of the

00467 opening about half the extent of the rubber seal

00468 direction inwards, that is, in the same direction.

00469 This also means that the rubber seal with a little

00470 is considerably wider than previously formed 00471 det. Rather, the stabilizing part has suitable

00472 extension, which of the usual

00473 Width or extension inside the rubber seal

00474 corresponds. Relative to a diameter of the opening in

00475 of the holding plate of the dust filter bag is the first

00476 stretching the stabilizing part inwards for example

00477 wise 1/10. Accordingly, the usual

00478 se circular rubber seal about the dimension of

00479 2/10 of the diameter of the opening inwards. A holding

00480 plate of a dust filter bag, as discussed here

00481 is, for example, has a multi-layer structure. 00482 It is made from several layers of cardboard-paper material

00483 composed. In this respect, the stabilization

00484 tion part preferably on one in direct contact

00485 with the rubber seal located position of the holding plate

00486 molded on. It is also recommended that the stabilization

00487 rung part on the side facing away from the dust bag

00488 rubber seal to arrange. In particular, the stabilization

00489 can also be tongue-shaped. 00490 00491 The invention also relates to a generic

00492 vacuum cleaner, in particular with a holder for one

00493 dust filter bag, with a drag

00494 kel or a closure plate with an actuating

00495 jump is formed for actuating a slide

00496 as a closure element on a dust filter bag, wherein

00497 the actuation lead in its extension

00498 direction is resilient and overall

00499 is pivotable against a spring. The pivotability

00500 is given relative to the closure plate. In detail

00501 is also referred to EPA 12532057, inso-

00502 far than with the basic structure of the vacuum cleaner

00503 the holder for the dust filter bag and the holding plate

00504 te, which is movably attached to the receptacle,

00505 fen. 00506

00507 The actuating

00508 formed projection, which for actuating one in the

00509 dust filter bag integrated slider or closure

00510 slider is used. With regard to such a dust filter

00511 today there is a technical problem, the actuation

00512 movement of the slide, acting on the dust filter bag

00513 as reliable and safe as possible with

00514 caused minor wear or general

00515 pregnancy of the dust filter bag and in particular the

00516 to reach the holding plate. In this regard, the

00517 invention that the actuating projection on the

00518 end plate is connected, such that in the course of a

00519 deflection of the actuating projection at the same time a

00520 swiveling can be initiated. The connection of the operating

00521 protrusion on the closure plate causes

00522 a compression, in which initially a linear compression

00523 slide of the actuating slide takes place, the distance

00524 increases between the tying locations. If you now

00525 uses a tape or the like to connect 00526 this streamlined and reached a state in which it

00527 can no longer lengthen significantly. If another 00528 pressure is exerted on the locking plate, the actuator

00529 lead therefore towards the closure plate

00530 gen, so that it is already in the course of the further operations

00531 pivoting of the actuation

00532 jump to the locking plate, but earlier,

00533 is coming. This has also achieved a

00534 tongue, since with increasing deflection of the actuator

00535 in the linear direction also by the

00536 tip of the actuating projection on the holding plate of the

00537 Dust filter bag applied pressure increased. Through the

00538 connection, which is limited in length, is an early

00539 abort this compression movement under increased

00540 pressure exerted on the holding plate than when moving

00541 process without the connection. In a further embodiment

00542 device is provided that the connection consists of a flexible 00543 slack connection means. The connection means 00544 tel can be a ribbon or a cord.

00545

00546 In a further solution to the problem presented, 00547 is also provided that the actuating projection has lateral support elements for supporting on a frame of the 00549 receptacle. The side support elements can be

00550 bar on the actuating projection. par-

00551 if, as preferred, as a plastic injection

00552 is partially formed. The recording continues to

00557 projection on the closure plate,

00558 the side supports slide on the mentioned sliding

00559 gen. It is essential that through these supports a

00560 force load, which first on the holding plate of the 00561 dust filter bag a movement of the closure plate

00562 recording in the closed position adjusts itself

00563 has a certain value or range. About that

00564 the force derived from the supports is derived from

00565 the inclusion of the dust filter bag added. 00566

00683 The illustrated electric vacuum cleaner 1 is a hand-held device

00684 designed. It has a housing 2, on which

00685 a handle 3 connects with the end handle 4. In

00686 transition area between handle 4 and handle 3 is located

00687 an on / off switch 5. The electrical cable connection

00688 is designated by the number 9. 00689

00690 The housing 2 is divided into a motor housing 6 and

00691 an extending chamber 7 for receiving

00692 of a dust filter bag 8. The motor fan is drawn

00693 risch not reproduced in detail. 00694

00695 The side of the dust filter

00696 beuteis 8 is in the operating position of the vacuum cleaner

00697 according to FIG. 1 in connection piece connection to one

00698 Blower air duct of the engine blower. 00699 00700 The motor housing 6 merges into a pipe coupling 00701 10 on the underside, which produces the air flow connection to a suction nozzle 00702. 00703 00704 With regard to the suction nozzle 11, it can be a so-called 00705 th suction / brush nozzle, which contains a 00706 brush roller in the nozzle mouth, which is set in rotation by a separate drive 00707. 00708 00709 The blower motor therefore works from the bottom upwards, 00710 consequently presses the dust air into the dust filter arranged above the 00711 motor housing 6 00712 bag 8 and the same 00716 narrow sides. In Figure 1, the vacuum cleaner can be seen from the 00717 broadside. 00718 00719 The chamber 7 corresponding to the cross-sectional dust filter bag 8 00720 is formed by a wire basket-stiffened 00721 textile bag 12 which merges into a stiffened edge in the form of a filter frame 00723 mens 13 at the bottom, ie on the motor housing side. The stiffened textile sack 12 can be assigned 00724 to this filter frame 13 by means of the detachable clip-in connection 00725. The plug-on area is offset from 00726. 00727 00728 To remove the dust filter bag, the housing 00729 se 2 can practically be opened with its cross-section 00730 fully released. The opening position results from 00731 Figures 1 (here in dash-dotted lines), 3, 4 00732 and 11 to 13. The folding axis 14 00733 that enables this is located on one narrow side of the housing 2. 00734 Your filter frame-side bearing eyes are denoted by 15. 00735 net. These bearing eyes 15 are located at the transition area

00736 between narrow side and wide side of chamber 7. Between

00737 εchen two bearing eyes 15 extends a continuous

00738 of the bearing eye of the motor housing 6. 00739

00740 In the area of the joint of motor housing 6 and

00741 chamber 7 is also a drag cover T in shape

00742 integrated an intermediate carrier on which the dust

00743 filter bag 8 sits. Such an intermediate carrier T

00744 is from German Offenlegungsschrift 39 11 580 of

00745 applicant known. It will be fully relevant in this regard

00746 referred to this document. 00747

00748 The drag cover T has a housing cross section

00749 adapted floor plan, occurs from the wall of the

00750 housing 2, however, so that it can be seen in FIG

00751 apparent coaxial position of motor housing 6 and

00752 chamber 7 essentially completely hidden from view

00753 is. The drag cover T is also foldable

00754 det, the drag cover T being flat on the hinge side.

00755 if, like the filter frame 13, two bearing eyes

00756 trains. Here, the drag cover T folds over diesel

00757 be folding axis 14 as the chamber 7. 00758

00759 The one immediately following the drag cover T

00760 dust filter bag 8 has a holding plate 16

00761 trained floor. Its general layout

00762 also speaks of the cross-sectional shape of the filter frame

00763 13, which is used to support the holding plate 16

00764 forms on the inner wall edge steps 17 - This allows the

00765 Holding plate 16 not in the opened position of the device

00766 slip into chamber 7. The common folding axis

00767 se 14 of filter frame 13 and drag cover T stretched

00768 approximately at the level of support level 17 of the filter bag

00769 tel holding plate 16. 00770 With housing 2 closed, ie in the operating position of the

00771 vacuum cleaner 1, the blower air duct of the motor

00772 blown with a stepped, cylindrical muzzle end

00773 in the lower area 18 'of an intake port 18. Last-

00774 rer protrudes over the top of the drag cover T,

00775 wherein the suction nozzle 18 is the same as the drag cover T.

00776 is integrally formed and wherein the suction nozzle 18, a transverse

00777 cut corresponding opening 19 of the filter bag holding

00778 plate 16 penetrating, edge-closing in the interior

00779 of the dust filter bag 8 protrudes. 00780

00781 The suction nozzle 18 tapers to its free end

00782 out so that its insertion into the opening 19 practical

00783 has a centering effect. 00784

00785 To remove the dust filter bag 8, the chamber 7

00786 with the drag cover T after loosening one on the housing side

00787 locking device in the open position shown in FIG.

00788 position pivoted. Now around the dust filter bag 8

To release 00789 for removal, the drag cover T from

00790 of the chamber 7 folded down, for which a handle 20 on the

00791 the upper side of the drag

00792 kels T is provided. This handle 20 is over a

00793 Film hinge on the top of the drag cover T

00794 arranged foldable. 00795

00796 To in the operating position of the vacuum cleaner according to the figure

00797 1, due to the falling position of the dust filter bag

00798 telε 8, a fall back of suction material in the area deε

00799 engine housing 6 can be avoided at the free end

00800 of the suction nozzle 18 a valve flap can be formed. 00801

00802 At the bottom, i.e. at the suction port 18

00803 turned side of the drag lid T, this is one

00804 pivotable plate 21 for holding an actuating device 00805 jump B assigned. This plate 21 is over a

00806 hinge 22 at the free end of the Schleppdeckelε T

00807 pivotally arranged. The plate 21 extends from

00808 the hinge 22 starting approximately to the middle of the

00809 drag cover T enclosing the suction nozzle 18.

00810 For this purpose, the plate 21 has a long-bore type

00811 break 23. The area of the hinge 22 facing away from the

00812 plate 21 is tapered. In this area

00813 is a receiving chamber which is rectangular in cross section

00814 24 arranged positively, which over the end region

00815 of the plate 21 protrudes. In this receiving chamber 24

00816 the actuation projection B is freely displaceable

00817 device, the actuating projection B being essentially

00818 chen from an actuator with a rectangular cross section

00819 gungsarm 25 and one at the free end of this actuator

00820 poor 25, i.e. that facing away from the receiving chamber 24

00821 end integrally formed actuating lug 26. The

00822 actuating nose 26 points in the position according to FIG. 3

00823 towards the dust filter bag 8. 00824

00825 The actuation projection B is in its extension

00826 direction springy. This is done in the

00827 receiving chamber 24 arranged compression spring 27, which

00828 one on the protruding into the receiving chamber 24

00829 end of the actuating arm 25 arranged pin 28th

00830 includes. At the other end, the compression spring 27 is supported

00831 from an end wall 29 of the receiving chamber 24. Latter

00832 is closed with a cover 30, which 00833 clamps the end wall 29 and the side walls of the receiving chamber

00 834 24 includes. In the open end area, i.e. in the loading

00835 rich, in which the actuating arm 25 came into the receptacle

00836 mer 24 protrudes, the lid 30 has one after

00837 inner protruding collar 31. The latter serves as

00838 limit stop for the by the compression spring 27 in

00839 outward direction loaded actuator arm 25, which 00840 has a corresponding, corresponding support edge 32 00841. 00842 00843 The plate 21 and the actuation 00844 projection B carried by it can be pivoted against a spring 33 about the hinge 22 00845. This spring 33 extends between the underside of the drag cover T and the side of the plate 21 assigned to this 00847 underside. For this purpose, 00848 on the underside of the drag cover T is a corresponding 00849 de recess 34 for receiving one end of the spring 00850 33 trained. The other end of the spring 33 comprises 00851 a circular projection 35 of the plate 21 in the region 00852 of the transition from the plate 21 to the receiving chamber 00853 24. The spring 33 always loads the plate 21 and the actuating projection B connected to 00854 in the 00855 direction the dust filter bag 8. The pivoting path 00856 of the plate 21 is limited in such a way that when the drag cover T pivots 00857 away from the dust filter bag 00858 8 or from its holding plate 16, the plate 21 00859 with the edge of the area in the opening 23 00860 protruding projection 35 on an outer edge 00861 collar 36 of the suction port 18 (see FIG. 00862 12). As already described further above in detail, the spring 33 is also of particular importance for 00864 for the further implementation and, in particular, the completion of the 00865 closing movement when the vacuum cleaner is opened. 00866 00867 The dust filter bag 8 is essentially composed of 00868 the holding plate 16 already mentioned and a dust bag 00870, for example adhesively bonded to the 00869 underside of this holding plate 16, preferably made of paper. 00872 00873 The holding plate 16 has a contour almost corresponding to the inside 00874 of the filter frame 13 and settles 00875 made of four layers of cardboard

00876 pier material together. These layers 38 to 41 are

00877 glued to each other. The holding plate 16 thus formed

00878 is supported when the dust filter bag is inserted

00879 means 8 on the edge steps 17 of the filter frame 13. Around

00880 a sagging of the dust filter bag 8 in the operating

00881 to prevent the vacuum cleaner 1 according to FIG. 1,

00882 locking devices 42 are provided, which on the

00883 inside of the filter frame 13 are arranged and on

00884 act the top of the holding plate 16. The dust filter

00885 bag 8 is thus in the area of its holding plate 16

00886 locked. 00887

00888 For the correct and safe allocation of the dust filter bag

00889 item 8 has the holding plate 16 in the area of both switches

00890 pages orientation features 43 that fit into

00891 counter features 44 of the inner wall of the filter frame 13

Intervene 00892. Regarding the orientation features

00893 are trapezoidal projections on the narrow side

00894 of the plate-shaped body forming the holding plate 16

00895 pers. How to achieve an orientation-oriented location

00896 between opening 19 and suction port 18. 00897

00898 The holding plate has on the longer side edges

00899 16 gripping openings 45. Both gripping openings 45 are

00900 beveled and to the corresponding inner wall of the

00901 filter frame 13 open. In the open position of the

00902 housing 2 and after swiveling the drag cover T

00903 can be pulled in like a wasp waist

00904 NEN central zone of the holding plate 16 of the dust filter bag

00905 8 can be easily gripped and lifted out of the chamber 7. 00906

00907 As already mentioned, the holding plate 16 is exposed

00908 four layers 38 to 41 stacked together,

00909 where on the underside 41 of the paper 00910 dust bag 37 is glued. This lowest layer 41

00911 has a circular opening 46. The above this

00912 layer 41 arranged layer 40 is contour and surface

00913 formed the same as the layer 41 and also has

00914 a through-hole arranged coaxially to the opening 46

00915 break 47, which is also the same radius as the

00916 has breakthrough 46. 00917

00918 The layer 39 arranged above the layer 40 is

00919 position for the layer 38 forming the ceiling

00920 det and serves to form a free space 48. FIG. 10

00921 shows a top view of position 39 with omission

00922 of the layer 39 lying above this layer and forming the ceiling

00923 layer 38. Layer 39 is essentially as one

00924 have the same outer contour as the other three layers -

00925 the edge strip formed. Specifically, this is

00926 triggers that in the area of the opening 47 of the layer 40

00927 layer sections 49 to 51 arranged on the outside

00928, which are from the respective outer edge to *

00929 extend near the opening 47, leaving it

00930 a distance between the opening 47 and the interior

00931 edge of the respective layer strip. The on the longitudinal

00932 th the holding plate 16 arranged layer strips 49 and

00933 51 are on the front side facing the opening 47

00934 connected to the layer strip 50 and extend

00935 starting from this to the area of the gripping

00936 gen 45, which gripping openings 45 by corresponding

00937 recesses in the layers 38, 40 and 41 are formed.

00938 The distance between the two inner edges of the

00939 layer strips 49 and 51 is chosen larger than

00940 the distance between the mutually facing edge edges

00941 of the gripping openings 45- on the layer strips 49 and

00942 51 Set opposite side of gripping openings 45

00946 the layer strip sections 49 'and 51' thicken

00947 such that they extend from the outer edge of the holding plate 16.

00948 going down to the central area of the holding plate

00949 16, leaving a slot 52. This

00950 widened areas of the layer 39, which consequently

00951 ge in the end area opposite the opening 47

00952 richly arranged the holding plate 16 are with the

00953 reference numerals 53 and 54. In the transition

00954 rich between the layer strip sections 49 'and 51'

00955 and areas 53 and 54 are thus in the longitudinal direction

00956 ung of the holding plate 16 acting stops 55 are formed. 00957

00958 The top layer 38 forming the ceiling has a

00959 same and almost also in terms of area training

00960 like layers 40 and 41. Here too is coaxial to the

00961 openings 46 and 47 an opening 56 is provided.

00962 These openings 46, 47 and 56 form the already

00963 imagined opening 19 of the holding plate 16. The top layer

00964 38 is also one with a slot 52 above it

00965 the layer 39 arranged, open to the edge and almost the

00966 same width as the slot 52 having recesses

00967 57 provided. This recess 57 extends from

00968 the narrow side of the opening opposite the

00969 holding plate 16 starting in the direction of the longitudinal extension

00970 ung of the holding plate 16 to about the middle of the latter. 00971

00972 Between the two lower layers 40 and 41 is one

00973 rubber seal 58 inserted and preferably glued. This

00974 rubber seal 58 is in the area of the openings 46 and

00975 47 arranged and has a circular opening 59,

00976 which is smaller in diameter than the diameter

00977 breaks 46 and 47. The opening 59 of the rubber seal 58

00978 is coaxial with the openings 46 and 47.

00979 aimed. The rubber seal 58 is used by the opening 00980 tion 59 stepping into the interior of the dust filter

00981 beuteis 8 protruding suction nozzle 18 for sealing

00982 closure between the dust filter bag 8 and the suction

00983 nozzle 18. 00984

00985 In the formed between layers 38 and 40 and by

00986 the layer strip of layer 39 is limited free space 48

00987 a locking element V slidably mounted (see.

00988 Figure 10). The closure element V has here

00989 drew up a spade-like plan, with a

00990 spade handle 60 in the position shown in Figure 10 in

00991 the slot 52 of the layer 39 lies. The one with the spade

00992 stem 60 connected closure plate 61 has an almost

00993 the distance between the inner edges of the layer strips

00994 fen 49 and 51 or the layer strip sections 49 'and

00995 51 'corresponding width and extends in the

00996 position according to Figure 10 of the stops 55 of the position

00997 39 starting to the edge of the opening 47 of the

00998 layer 40 or up to the edge of the opening 19. 00999

01000 The spade handle 60 of the closure element V lies here

01001 with the exception provided in the top layer 38

01002 mung 57 free and serves as an operating section. For this

01003 the spade handle 60 has a manipulation advantage

01004 M in the form of a kink 62. This results in

01005 the free end of the spade handle 60 a bendable

01006 section 63.01007

01008 It is also conceivable to design the manipulation projection M in this way

01009 that at the free end of the spade step

01010 les 61 a thickened area is arranged. Alternatively

01011, a recess in

01012 provided a longitudinal slot or the like

01013. 01014 01015 is due to this design of the holding plate 16

01016 it is now possible to open the opening 19 by means of the

01017 element V either to be closed or opened.

01018 Here the closure element V in the area of the free

01019 space 48 of the layer 39 is shifted longitudinally, the

01020 closing element V in both the locking and open position

01021 as well as in every intermediate position in the outer

01022 tur of the holding plate 16 is completely included. This

01023 means that neither the shutter nor the

01024 open position parts of the closure element V over the

01025 protrude outside contour of the holding plate 16. This is at

01026 the exemplary embodiment shown is also not possible because

01027 the shape and size of the filter frame 13 of the vacuum cleaner

01028 1 no enlargement of the outer contour of the holding plate 16

01029 would allow. 01030

01031 The locking element V is moved by

01032 grasping or attacking the manipulation device

01033 jump M, which in the area of the recess 57 of the upper

01034 most layer 38 exposed for attack. This recess 57

01035 is adapted in the longitudinal extent to the displacement path 01036 of the closure element V. By moving the

01037 closure element V from the open position according to the figure

01038 10 in a closed position in the direction of arrow y

01039 the opening 19 of the holding plate 16 is closed by means of the

01040 end plate 61 closed. The closure element V

01041 is laterally through the layer strips 49 and 51

01042 led. The end position of the closed position is

01043 is sufficient if the end face of the closure plate 61

01044 the inner edge of the face layer layer

01045 fens 50. 01046

01047 The open position is

01048 impact of the closure plate 61 against the stops 55 of the

01049 layer 39 defined. 01050 For removing a holding plate 16 of this type

01051 provided dust filter bag 8 from the chamber 7

01052 this first together with the drag cover T from the

01053 operating position according to FIG. 1 in a removal position

01054 pivoted according to Figure 3. As from this illustration too

01055, this is the one with the actuation projection

01056 B provided, pivotable plate 21 in a parallel position

01057 the drag cover T between the latter and the holding plate

01058 te 16. The actuating lug 26 of the actuating projection

01059 B reaches behind the foldable section 63

01060 of the spade handle 60 of the closure element V. Will

01061 then the drag cover T by means of the handle 20

01062 pivoted away from the chamber 7, so that causes

01063 bendable section 63 attacking operating lug

01064 26 a displacement of the closure element V into the

01065 Final position of the opening 19. In the course of the pivoting

01066 of the drag cover T swings the plate at the same time

01067 21 with the actuation projection B around the hinge 22,

01068 due to the spring 33, such that the kinkable

01069 Section 63 of the closure element V at least over

01070 a large part of the pivoting path of the drag cover

01071 T is always acted upon by the actuating nose 26. It

01072 there is a scissor-like opening between the

01073 drag cover T and the one with the actuating projection B

01074 plate 21. Due to the fact that the actuator

01075 gungsar 25 resiliently mounted in the receiving chamber 24

01076 iεt, this can be in accordance with the course of movement in

01077 evade the receiving chamber 24. The resilient support

01078 the actuation projection B and the resilient

01079 pivoting of the plate 21 and of the connected

01080 an actuation projection B ensure εtetε the

01081 rear grip of the actuating lug 26 behind the bendable

01082 section 63 over the entire displacement path of the

01083 closure element V. As soon as the closure element V the

01084 closure position of opening 19 is reached, is supported, 01085 as already mentioned, the front edge of the closure element

01086 tes V or the closure plate 61 on the inside

01087 edge of the layer strip 50 from the layer 39. In the-

01088 this position also reaches the kink 62 of the spade

01089 handle 60 the end edge 64 of the recess 57 of the upper

01090 first position 38. The actuation projection B is in this

01091 position continues to strive to continue the closure element V.

01092 in the direction of arrow y. The actuation

01093 nose 26 still engages behind the foldable

01094 Section 63 of the spade handle 60. In the course of the further

01095 Swiveling the drag lid T away from the chamber 7

01096 the actuating nose 26 is now reached under

01097 under the bendable section 63, which, thereby

01098 and due to the still prevailing

01099 stroke in the direction of arrow y, upwards, i.e.

01100 through the recess 57 of the uppermost layer 38

01101 tend, buckles. Here is a second articulation

01102 set 65 (see Figure 11). This shows that

01103 the spade handle 60 in width as the recess 57

01104 can be formed, possibly even narrower

01105 as this, otherwise the one from the actuating lug 26

01106 acted upon or under attacked area in the figure

01107 11 position can not evade. This would

01108 to a destruction of the closure element V in the area

Guide 01109 of the contact surface of the actuating nose 26. As far as OHIO, however, the displacement of the closure elements and the

01111 action on the spade handle 60 not via a

01112 kung realized, but only by one

01113 the spade handle. applied manipulation

01114 jump M, it is also possible and preferred that

01115 the Spatenεtiel 60 with a larger width than that

01116 recess 57 is formed so that the edges of the

01117 recess from the spade handle are underneath. 01118 01119 In the course of the further pivoting of the drag cover T

01120 in a position releasing the dust filter bag 8

01121 according to FIG. 12 passes over the actuation projection B.

01122 of the actuating lug 26, the bendable section 63,

01123 with which the latter, the recess 57 of the top layer 38

01124 pushing through, superscript. The actuation

01125 jump B reaches a predefined end position 01126 by, as already described, the

01127 break 23 of the plate 21 protruding projection 35 itself

01128 is supported on the collar 36 arranged on the outer edge side of the suction nozzle 18. The drag cover T can also

01130 still further than in the 90 "position shown in FIG

01131 can be pivoted so that the dust filter bag 8 pro-

01132 can be easily removed from chamber 7. 01133

01134 To remove the dust filter bag 8, this is in the

01135 area of the gripping openings 45 of the holding plate 16 gripped

01136 fen and against the locking action of the locking devices

01137 42 of the filter frame 13 pulled out of the chamber 7. 01138

01139 If a dust filter bag 8 that is closed in this way is nevertheless to be used, the 01140 is opened

01141 opening 19 in the simplest way. For this, the towing

01142 cover T back towards chamber 7.

01143 swivels, so that the actuation projection B with the free

01144 and the end region of the actuating arm 25 which

01145 edge 64 of the recess 57 of the holding plate 16

01146 kink 62 acted upon. In the course of the further verse

01147 swiveling the drag cover T into the closed position

01148 the actuation projection B shifts the locking element

01149 ment V in an open position of the opening 19 by the

01150 actuating arm 25, the closure element V in the area

01151 pushes his spade handle 60 in front of him. How ready

01152 mentioned earlier is in this context

01153 especially the length changeability of the actuator 01154 projection B against the compression spring 27 of meaning

01155 tung. Namely, when due to an unfortunate

01156 angular position when the actuation

01157 jump B on the spade handle 60 itself a blocking

01158 would set. Instead,

01159 next the length of the actuating arm 25, whereby

01160 also the angle of action on the spade handle 60

01161 changes, so that a possibly resulting self-

01162 inhibition or blocking can be overcome. in the

01163 further course of the pivoting movement of the drag cover

01164 T also closes the scissor-like arrangement of

01165 drag cover T to plate 21 and the arranged thereon

01166 th actuation projection B. After fully opening

01167 of the opening 19 of the holding plate 16, with corresponding

01168 corresponding edges of the closure plate 61 at the stops

Support 01169 55 of position 39, the actuation projection 01170 jumps B in the area of the free end of the actuating arm.

01171 with 25 the bendable section 63 and sits with

01172 of its actuating nose 26 in turn behind this section 01173 63. It is also important here that the

01174 actuation projection 26 against a housing-fixed

01175 stroke 26 'moves (see, for example, Fig. 3). this happens

01176 also preferred under a certain noise

01177 lung, which the user a proper opening

01178 condition of the filter bag and overall a functional

01179 nell perfect operational readiness of the vacuum cleaner

01180 signals. 01181

01182 The dust filter bag 8 shown and described

01183 is also in vacuum cleaner 1 with its holding plate 16

01184 can be used, which no device for automatic

01185 Closing or opening in the course of opening or closing

01186 outside of the vacuum cleaner. Here now exists

01187 also the possibility of the closure element V by hand in

01188 to shift the respective position by 01189 re section 63 is gripped by hand and thus a

01190 displacement of the closure element V can take place.

01191 There is also the option of

01192 element V in the area of the gripping openings 45,

01193 by using the clamp grip between layers 38 and

01194 40 in this area exposed closure element V

01195 is gripped and relocated. This also works in

01196 the concrete example as it is shown in the

01197 game is shown, in which the closure element only up

01198 to the edge of the contour of the holding plate 16 in the area of

01199 gripping openings 45 is sufficient and not over this contour

01200 protrudes. 01201

01202 When using a vacuum cleaner 1 with a like

01203 shown and described actuating projection B

01204 is also a use of conventional

01205 dust filter bags, i.e. Dust filter bags without

01206 closing element V, conceivable. Here would be a

01207 ken of the drag cover T in an open or closed

01208 Position of the actuation projection B over the holding plate

01209 16 run away without any functions

01210 would lead. 01211

01212 Finally, it is also possible to plate 21 of the

01213 drag cover T with registration protrusions.

01214 These registration tabs move after the

01215 pivoting of the actuating projection B into corresponding

01216 registration openings, which in the embodiment shown

01217 can be, for example, the gripping openings 45 of the holding plate 16

01218 can, a. Here the training is made so

01219 that a closing of the vacuum cleaner 1 only in the

01220 registration openings or gripping openings 45 retracted

01221 registration protrusions is possible. This device

01222 should serve to ensure that the vacuum cleaner 1 is closed

01223 is only possible when the dust filter bag 8 is inserted. Is 01224 a dust filter bag 8 inserted into the chamber 7, so

01225 pivots the actuation projection B, as already

01226 described in the course of the closing movement towards

01227 the underside of the drag cover T, with which also the

01228 registration tabs are shifted accordingly, and

01229 so that in the closed position of the chamber 7 for

01230 drag cover T in the corresponding registration openings

01231 or gripping openings 45 can occur. But it is

01232 no dust filter bag 8 is inserted, the actuator

01233 projection B no abutment for pivoting, with what

01234 the registration protrusions remain in their locked position

01235 ben. In this locked position, they are supported in the course

01236 of the closing movement of the drag lid T, for example

01237 on the outer edge of the filter frame 13, with which one

01238 closing the vacuum cleaner 1 is counteracted. Become

01239 registration tabs of different sizes

01240 according to different sized registration openings

01241 assigned, it is also a correct insertion of the

01242 dust filter bag 8 guaranteed in the chamber 7. 01243

01244 Shown and described, initially with reference to

01245 Fig. 14 in a second embodiment, a

01246 Holding plate 101 of a dust filter bag. The holding plate

As can be seen from FIG. 15, 01247 te 101 is a total of four

01248 built up (Fig. 15 is a greatly enlarged

01249 illustration). An upper layer 102 has a circular

01250 en opening 103 with an opening edge 104. Further in

01251 the upper layer 102 a - wider - slot 105 formed -

01252 det. Under the upper layer 102 there is a displaceable one

01253 closure element V arranged. The closure element V

01254 is at its style end with an attachment 106,

01255 which in the exemplary embodiment is also made from a layer of cardboard

01256 stands, missed. The attachment 106 protrudes into the slit opening

01257 105. Mean of this essay 106 is the 01258 locking slide V by hand or automatically displaceable 01259 bar. 01260 01261 The closing slide V is shown in FIG. 14 with regard to its outer dimensions by the dash-dotted line 01263. The opening 107 of the middle layer 108, ie 01264 of the third layer from the top of the holding plate 101, is larger than the - upper - opening 103 or the 01266 lower opening 109 (cf. FIG. 15). Between the layer 108 01267 and the lowest layer 110 of the holding plate 101, a 01268 rubber seal 111 is held. For example, the rubber 01269 seal 111 is secured by gluing between the layers 108 and 01270 110. The rubber seal 111 extends 01271 from the opening edge 104 in a ring shape towards 01272 inside and has an inner opening edge 112. 01273 01274 Shaped to the middle layer 108, ie the third layer 01275 from above of the holding plate 101, is a stabilizing part 01276 in the form a tongue 113. The tongue 113 is formed on the 01277 most distant location (based on the retracted position 01279 according to FIG. 14) of the opening 103 from an end edge 114 of the closure element V. 01280 01281 Due to the formation of the tongue 113 on the layer 108 of the 01282 holding plate 101, it follows that in the embodiment 01283 it also consists of a cardboard paper material 01284, like the other layers of the holding plate. 01285 01286 The tongue 113 has an extension e, starting from 01287 the opening edge 104 into the interior of the opening 103, 01288 which corresponds approximately to half the extension E of the rubber seal 111 from the opening edge 104 into the interior of the 01290 opening 103. In the embodiment example 01291, a diameter d of the circular opening 103 is approximately 5 cm. 01292 The extension e corresponds to approximately 1/10 of this diameter 01293 sers, i.e. about 5 mm, whereas the rubber seal

01294 111 extends about 1 cm into the interior of opening 103

01295 (dimension E). 01296

01297 The sectional view of FIG. 16 shows a section

01298 in the plane between layers 115 - the second layer

01299 from above - and the situation 108. To indicate that this

01300 layers are glued together and thus together

01301 is the cutting plane, insofar as it matches the

01302 Adhesion matches, in hatched representation

01303 reproduced. 01304

01305 It can be seen that the tongue 113 directly on the

01306 layer 115 is formed. Between layer 115 and the

01307 layer 108 is the rubber seal 111, which

01308 The outer edge is only partially circular. 01309

01310 From the representations of FIGS. 17 and 18, the behavior

01311 of the tongue 113 and the effect of the tongue 113 in the loading

01312 operating status of the vacuum cleaner can be seen. 01313

01314 This is a vacuum cleaner in detail

01315 with a so-called drag cover 116, on which a

01316 suction pipe 117 is formed. The characteristics of the dust

01317 sucker is described in detail, for example, in EP A 25

01318 32 057, the content of which is hereby fully contained in

01319 the disclosure of the present application, also for the purpose

01320 an inclusion of such features in the claims,

01321 is included. 01322

01323 The suction pipe 117 passes through the openings 103 and 109

01324 and the openings of the layers in between

01325 holding plate 111. The dimensions of the openings and in particular

01326 the dimension of the tongue 113 is on the diameter of the suction

01327 tube 117 so that there is a kink 01328 of the tongue 113 in the interior of the dust bag. The

01329 seal 111 covers tongue 113 completely -

01330 and protrudes radially inwards - and lies

01331 on the exhaust pipe 117 to the full extent. With a man

01332 pull the suction tube 117 out of the holding plate 101

01333 of the dust filter bag remains due to the success

01334 bend the tongue 113 after a certain preload

01335 inside and a corresponding action of the tongue 113

01336 on the rubber seal 111. This has the consequence that

01337 the rubber seal 111 in any case not upwards in

01338 extends towards the opening 103 and thus the device

01339 closing element V can be closed easily. in the

01340 state of closure, the closure element V runs on the upper side

01341 on the tongue 113 - based on an illustration

01342 tion according to FIG. 15. 01343

01344 With reference to FIGS. 19 and 20, in cross section, partially

01345 wise, a receptacle 118 for a dust filter bag

01346. With regard to the dust filter bag, a holding plate 101 can be seen in particular in cross-section, 01348 as has already been described above.

01349

01350 The vacuum cleaner or the holder 118 has a

01351 end plate 119, with the already mentioned suction

01352 tube 117. An actuating projection 120 is also closed

Recognize 01353, which has a nose 121 with which it faces

01354 the closure element V of the dust filter bag acts.

01355 The actuation projection 120 is in a receptacle 122

01356 can be moved linearly against the force of a spring 123.

01357 Next, the slide gate 120 is over a band 124 -

01358 directly - connected to the closure plate 119. in the

01359 individual is the connection point 125 of the band 124 to the

01360 closure plate 119 on the underside, near one

01361 swivel joint 126 formed. 01362 01363 In the position shown in Fig. 19, in which

01364 the actuating slide 120 only on the holding plate

01365 te 111 of the dust filter bag is band 124

01366 in a relaxed position. It has another

01367 certain length stock that can be used. 01368

01369 In the position shown in FIG. 20, a rotary

01370 movement of the closure plate 119 has been initiated, so

01371 that this about the axis of the joint 126 on the holding

01372 plate 111 of the dust filter bag swings out. at

01373 this movement remains the relative position of the

01374 actuation protrusion 120 relative to the holding plate 111

01375 unchanged. The actuation projection 120 moves single

01376 borrowed something against the spring force of spring 123

01377 actuation projection 122 a. This movement can

01378 be continued until the tape 124 is tightened.

01379 This tightening occurs sooner than the ax. Run-in

01380 like the actuation projection 120 in the receptacle 122

01381 is used. Once the band 124 is tightened, kick

01382 by further rotation of the shutter plate 119

01383 the axis of the joint 126, as it were, pulling the

01384 actuation projection 120 so that this -

01385 means the mount 122 - around its articulation 127 around the

01386 closure plate 119 on the - underside - the closure

01387 plate 119 swiveled. That is another

01388 pressure build-up of the actuating projection 120 on the holding

01389 plate 111 deε dust filter bag counteracted. 01390

01391 For the rest, the general configuration of the

01392 holder and the locking plate and the actuating device

01393 also jumps to the unpublished documents

01394 referred to the German patent application 43 41 248. 01395

01396 Alternatively - which is not shown in detail

01397 is - can also on the actuating projection 120- 01398 loaned, that is, supports formed perpendicular to the plane of the drawing

01399 det. These supports can, for example, on the -

01400 inner - edge 128 the holder 118 for the dust filter 01401 bag come to rest. Through a suitable vote

01402 mung between the total length of the actuating projection

01403 120 and the arrangement of the supports can be achieved

01404 that the actuating projection 120 comes with its nose 121 01405 onto the holding plate 111 of the dust filter bag for the 01406 edition, but that in the case of the described swiveling of the closure plate 119 the resulting one

01408 increased force in the course of - linear - compression of the

01409 actuation projection 120 through the support edge 128

01410 is added. The receiving edge 128 or the supports,

01411 formed laterally on the actuating projection 120

01412, can then be further developed in detail

01413 be that they have as little friction as possible on each other

01414 slide. 01415

01416 In a further exemplary embodiment is described in

01417 ner type a closure plate 219 with suction nozzle 217

01418 via a swivel joint 226 opposite a vacuum cleaner housing

01419 se 202 pivoted. A head start

01420 220 on a plate 221 is pivotally attached to the free end of the closure plate 219 via a hinge 222 on 01421

01422 arranges. On axis 227 of hinge 222 is one

01423 spreader spring 233 arranged, which over a hose

01424 fe 234 on the underside 237 of the closure plate 219

01425 supports, being the circular shape of the suction nozzle

01426 217 adapted this encloses. By the power of

01427 Spreading spring 233 with the locking plate open

01428 219 this and the plate 221 slightly V-shaped.

01429 The opening angle of this V-shape is determined by striking

01430 of an L-shaped nose 224 which is connected to a

01431 long bore-like opening 223 for the nozzle 217 01432 closes, limited to this nozzle 217, cf. Fig.

01433 27. 01434

01435 The suction nozzle 217 is on with a valve flap 205

01436 provided its free end, which is a falling back of

01437 Suction material, due to the falling position of the dust

01438 terbeutels 208 in operating position, prevented. This is 01439 a rib-reinforced membrane that is simply riveted to a mandrel 218. 01441

01442 The plate 221 pivotally attached to the underside 237 of the closure plate 219 carries the plate against the

01444 force of two springs 228, 229 slidably mounted

01445 actuation projection 220. Fits in the extended position

01446 the outline of the plate 221 with the extended 01447 actuation projection 220 roughly corresponds to the outline shape of the

01448 closing plate 219 or the closing plate 219 and plate

01449 221 receiving inside of the filter frame 213.

01450 That means that the actuating arm 225 has approximately the same

01451 Width like plate 221. At its free end

01452 carries the actuating arm 225, slightly off-center

01453 sets, an actuating lug 216, which in the input

01454 described a closure element V of a retaining plate

01455 te 201 of the dust filter bag 208. 01456

01457 With reference to FIGS. 21 to 26, the mounting of the actuator

01458 tion projection 220 on the plate 221 explained in more detail.

01459 The plate 221 has vertically protruding, the actuating

01460 lug 220 side leg 230,

01461 231, which at its free end on the axis

01462 227 opposite side by means of a bolt 232

01463 connected. Between the bottom 235 of the plate

01464 221 and bolt 232 is the actuating arm 225 of the

01465 actuation projection 220 led. A blocking nose 236

01466 strikes the belt when relaxing springs 228, 229 01467 gel 232 and prevents it from being pulled out. The fairy-

01468 dern 228, 229 are U-shaped in cross section

01469 th channels 238, 239 deε actuation projection held.

01470 The free leg ends of channels 237, 238 lie on

01471 the underside 235. For better management of the

01472 actuation protrusions protrude from the free legs

01473 230, 231 of the plate 221 protrusions 240, 241, so that

01474 the channels 238, 239 between these projections and the

01475 underside 235 are held. Is in the longitudinal direction

01476 each channel 238, 239 closed at one end by a wall

01477 sen, on which the springs 228, 229 are supported. The

01478 opposite longitudinal end is open and support there

01479 the springs 228, 229 on plate-tight counter bearings

01480 242, 243. When the dust filter bag 8 is closed

01481 the actuating projection 220 initially against the force

01482 of springs 228, 229 towards opening 223

01483 postponed. The breakthrough 223 lies between the

01484 channels 238, 239 and can connect channels 238, 239

01485 the actuating arm 225 rounds off a rounded portion 244

01486. To limit the displacement of the actuation

01487 projection 220 on the breakthrough 223 are on the

01488 wall 245 of the nose 224 stops 246 provided on the

01489 the end face of the rounding 244 of the actuating

01490 jump 220 hits. 01491

01492 The holding plate 201 with the closure element V iεt im

01493 essentially according to the previous explanations

01494 gene trained. However, it shows the spade handle

01495 260 a manipulation lead in the form of an attachment

01496 261, cf. Fig. 28, the one with the ceiling

01497 top layer of the holding plate 201 completes. The width

01498 of the attachment 261 corresponds somewhat less than the pulp

01499 te deε for the actuation of the closure element V

01500 agile width of the slot in the uppermost layer of the

01501 holding plate 201, cf. see also Fig. 9. Against that of 01502 the top of the spade handle 260 and the long side

01503 of the angled space 261 formed by the

01504 lug 216 of the actuation projection 220 in motion

01505 direction, εo finding a counter bearing. Alternatively

A recess could also be provided for the attachment

01507. 01508

01509 When pivoting the locking plate 219 out of the in

27 shows the position shown in FIG. 28

01511 the plate 221 and the actuating projection 220

01512 the underside 237 of the closure plate 219. Missing that

01513 holding plate 201 and accordingly remains the V position between

01514 see the closure plate 219 and plate 221 or

01515 received the actuation projection 220, the

01516 Do not close locking plate 219. Registration tab

01517 ge 203, 204 on the plate 221, formed by a

01518 widening compared to the free end of the plate 221

01519 or the actuation projection 220, drive at maximum

01520 swiveling in registration recordings 206 from on the filter

01521 frame 213 inward projecting receptacles 207. Also

01522 this means that the vacuum cleaner can only be closed when the

01523 placed filter bag 208 possible. 01524

01525 When closed, cf. 28, 29 is the

01526 locking plate 219 locked by locking lugs

01527 209 openings 210 in the closing plate 219

01528 zen. The detents 209 can from a sealing edge

01529 212 protrude, at least over the longitudinal extent of the

01530 filter frame 213 freestanding on an angle 211 of the

01531 filter frame 213 is arranged. Against the smooth interior

01532 side of the sealing edge 212 comes in the closed

01533 state one on the outside of the closure plate 219

01534 all-round sealing lip 214 in sealing system. Also at

01535 this exemplary embodiment can, as already described

01536 ben, a connection of the actuation projection 220 to the 01537 closure plate 219, e.g. B. by a bendy slack

01538 connecting means take place in the course of a compression

01539 of the actuating projection 220 at the same time a
