Description

00001 vacuum cleaner with a motor housing 00002

The invention relates to a vacuum cleaner with a

00004 Motor housing, if necessary with a connected one

00005 filter chamber, and a device handle, the device

00006 handle in a plug-in receptacle of the motor housing

00007 ses can be plugged in and when the device is plugged in

00008 testieles a line attached in the motor housing

00009 control switch is operated. 00010

Such vacuum cleaners are known. So is in the

00012 WO 95/28867 specified a vacuum cleaner, which one in

Has the motor housing anchored device handle.

00014 the latter actuates when plugged into the motor

00015 housing or when pulled out of the same one

00016 switch arranged in the motor housing. The latter

00017 causes a condition-related electronically

00018 Activate or deactivate a motor housing side

00019 circuit breaker. When the device is plugged in

00020 Stieles in the motor housing is the circuit breaker

00021 electronically controlled in full load position,

00022 so that a further line connected in series

00023 switch in the handle or in a handle

00024 of the handle is activated. The control of the

00025 electric motor of the vacuum cleaner only takes place after this

00026 still on the device-side circuit breaker.

00027 When pulling the handle out of the engine

00028 housing the switch is operated such that a

00029 Changeover of the circuit breaker on the motor housing side

00030 takes place in a zero position. The latter is therefore the

00031 active circuit breakers. Vacuum cleaner with a peeled off

00032 Tool handle are preferred for over-floor work

00033 used, the power control of the suction

00034 motors via the circuit breaker on the motor housing side

00035 is done. With regard to the above-described prior art

00037 becomes a technical problem of the invention therein

Seen 00038, a vacuum cleaner of the type in question

00039 with regard to the changes caused by the handle

00040 Circuit of the motor-side circuit breaker

00041 to improve. 00042

00043 This problem is first and foremost

00044 solved the object of claim 1,

Is that the trained as a slide switch

00046 circuit breaker a remote control extension

00047 has the by inserting the handle

00048 simultaneous actuation of the circuit breaker

00049 strikes. There is therefore a switchover here

00050 mechanically. They are not prone to failure

00051 electronic parts and circuits required. The as

00052 slide switch trained circuit breaker in the motor

00053 housing has a cooperable with the device handle

00054 ren remote control extension on, with the help of the latter

00055 by inserting the handle into the motor housing

00056 the slide switch preferably in a full load position

00057 is relocated. Here too - as in the prior art

00058 technology already indicated - so that the engine housing

00059 termed circuit breaker is connected in series to one

00060 device-side second switch. This sits

00061 preferred in the area of a handle handle. loading

00062 is due to the series connection and the full load

00063 position of the circuit breaker on the housing is the

00064 with the handle inserted, the handling side

00065 switch activated. With the help of the latter can

00066 the power of the naturally aspirated engine can now be controlled.

00067 The remote control extension can be made of the same material

00068 with the operating range of the circuit breaker

00069 be bound. Further training can be done in this way

Be that when you pull the handle from the 00071 Motor housing the circuit breaker on the motor housing side

00072 automatically moves back to the zero position, this

For example, by means of a tension spring or the like.

This ensures that the naturally aspirated engine

00075 a removal of the handle is switched off.

00076 whose power control is then only about

00077 regulated the motor housing side circuit breaker.

00078 In an advantageous development of the invention

It is envisaged that the remote actuation

00080 set at its handle end a detent

00081 mung for interaction with a locking exception

00082 me on the handle. When the device is plugged in

00083 les in the motor housing catches the locking exception of the

00084 handle the latching extension of the remote control

00085 continues and relocates the via this extension

00086 circuit breaker in a full load position. A man

00087 pulling out the handle caused by the form

00088 coherent connection between the remote

00089 actuation extension and the locking exception of the device

00090 Stieles a relocation of the circuit breaker in

00091 the zero position. Here, for example, the remote control

00092 continued at least in the area of the catch formation

00093 be designed so that when the zero

00094 position of the circuit breaker at the detent

00095 a further pulling out of the device handle resiliently

00096 leaves the locking exception of the handle. For this

It is further proposed that a device handle side

00098 end of the remote control extension when pulled out

00099 of the implement handle in one position at most

00100 is dragged, which is opposite a mouth of the plug

00101 recording is relocated. The remote actuation

00102 set or its latching shape accordingly protrudes from

00103 do not pull the handle out of the plug receptacle

00104 beyond the mouth of the same, with which the remote

00105 extension always in a protected location within 00106 of the connector remains. To be particularly advantageous

00107 it turns out that the handle end of the device

00108 remote control extension in a gap between one

00109 plug-in receptacle inner wall and one in the plug receptacle

00110 arranged connector is slidable. Hereby

00111, the Fätätigungs lawsuit drives one guide and one

00112 secured position positioning within the plug-in

00113 me, which also ensures that the

00114 shaping by the locking recess of the handle

00115 ben. The connector located in the connector

00116 forms the electrical coupling to one in the device

00117 stem the assignable coupling part. Further

00118 it is proposed that the shift by a

00119 stop is limited on the back of a connector. E.g.

00120, the remote control extension can be a molded one

00121 have stop nose, which when pulled out

00122 of the handle against the back of the

00123 gene connector occurs to define the zero position

00124 of the circuit breaker. In an advantageous further

00125 formation of the subject of the invention is proposed

00126 that the outermost position of the handle end

00127 of the remote control extension in overlap with the

00128 connector is such that arranged on the connector

00129 contact flags over the free end of the remote control

00130 protrude continuously. This ensures that

00131 only a tool handle, the locking recess level

00132 protrudes beyond its connector, a relocation

00133 of the circuit breaker can cause. This is further

00134 training is particularly advantageous if

00135 genem handle for the power supply of the suction motor

00136 an adapted network coupling in the connector receptacle

00137 is introduced. This network coupling can be in the form, for example

00138 of a known IEC connector.

00139 The latter is inserted into the plug receptacle in such a way

00140 that the contact tabs of the connector on the motor housing side 00141 can be captured to form the electrical coupling

00142 den. Actuation of the actuation process

00143 does not take place here. This is also desirable because

00144 such a configuration of the motor housing side

00145 circuit breaker initially in a zero position

00146 should remain. This position should only be emphasized

00147 can be left by actuation on the switch side. 00148

The invention further relates to a vacuum cleaner

00150 with a motor housing, possibly with an attached

00151 closed filter chamber, and a device handle, wherein

00152 the handle of the device in a socket close to the housing

00153 motor housing is insertable and the plug

00154 has contact flags. Here is to improve

00155 coupling between the handle and motor housing

00156 hit that the plug in the plug receptacle

00157 is arranged offset such that the front ends

00158 of the contact flags at a distance from the mouth of the

00159 plug receptacle. The contact flags of the motor

00160 house-side connector are thus in such a

00161 inserted position within the plug receptacle,

00162 that this is not accidentally, for example when dropping

00163 of the vacuum cleaner can be bent. Likewise

00164 is thus a safe coupling within the plug-in

00165 would guarantee. The inner wall of the plug-in

00166 me offers lateral guidance of the device

00167 stick socket. It is also proposed that the

00168 plug cantilevered in the receptacle

00169 is. E.g. can the plug one against the

00170 connector receptacle cross section reduced cross section

00171 have. In the annular space thus formed between

00172 connector and connector receptacle inner wall can be

00173 extension of a device-side power

00174 switch, as already described, be positioned.

00175 The device handle to be inserted into the plug receptacle can 00176 for actuating this remote control extension

00177 protruding into the annular space formed

00178 have. The latter can, for example, extend one

00179 molded socket on this side

00180. The arrangement of the connector in the motor housing

00181 is preferably carried out in such a way that the plug has a

00182 plug base is fastened in the plug receptacle. The

00183 attached to the connector housing thus protrudes

00184 freely in the plug receptacle. The between connector

00185 and plug-in receptacle inner wall is formed

00186 in depth through the plug base, which

00187 sectional the internal cross section of the plug receptacle

00188 is adjusted, limited. This also means that

00189 stroke limitation for a device handle extension for

00190 actuation of the remote control extension of the power

00191 switch given. In order to transmit high mechanical

00192 shear loads between the handle and motor housing

To ensure 00193, it is proposed according to the invention

00194 that the handle of the device by a measure in the plug receptacle

00195 can be inserted, which is at least 1.5 times,

00196 preferably 2 times the largest free dimension

00197 corresponds to a handle cross-section. Will continue

00198 proposed that the dimension from the mouth

00199 of the plug receptacle to the foot of the contact lugs approximately

00200 corresponds to the largest dimension of the handle section

00201 speaks. It follows that the handle of the device

00202 preferably by the dimension from the mouth of the plug-in receptacle

00203 me up to the foot of the contact flags over the foot of the contact

00204 tact flags in between the cantilever

00205 plug and the receptacle inner wall formed

00206 Annulus enters. The cantilevered length of the housing

00207 side connector is selected accordingly. Further

00208 result from this configuration in the area of

00209 plug-in receptacle two areas with different tasks

00210 ben. The first associated with the muzzle 00211 area forms the electrical coupling area between

00212 see socket-side socket or instead of

00213 power socket and the housable

00214 side connector. The second subordinate area

00215 is a coupling area between the handle and

00216 a remote control extension of a device housing side

00217 gene circuit breaker, preferably the

00218 length of this second area, i.e. H. the length of the

00219 cantilevered area of the plug, such as the maximum

00220 len displacement path of the circuit breaker corresponds.

00221 Both areas together make up the mechanical coupling

00222 area between the handle and the motor housing,

00223 whose entire length is dimensioned so that high

00224 Forces and moments can be transmitted. In a

00225 advantageous development of the subject of the invention

00226 it is provided that the handle and / or a network

00227 socket one protrudes perpendicular to the direction of insertion

00228 existing locking pin which in a locking receptacle

00229 snaps into place. This locking serves

00230 for secure mounting of the device handle or the

00231 mains socket within the plug receptacle, which

00232 latching for releasing the connection only emphasized

00233 can be canceled. The on the handle or on

00234 the locking socket provided for example can.

00235 perpendicular to the direction of insertion in a latching direction

00236 be spring loaded. E.g. can the locking pin

00237 fen be provided with a compression spring on the underside. It

00238, however, training are conceivable in which the locking

00239 tap as a partially released from the housing shell

00240 cut, resilient section formed

00241 is. The snap-in recess on the receptacle

00242 taking the locking pin is in a preferred embodiment

00243 fertilizer in the already mentioned first area of the plug

00244 recording provided, d. H. in the field of electrical

00245 clutch. To remove the snap connection between 00246 handle or mains socket and plug receptacle

00247 proposed that the catch with an ejector

00248 is provided for disengaging the locking pin. By

00249 actuation of the ejector, the locking pin is such

00250 preferably against a spring force, shifted that

00251 then pulling off the handle or the mains

00252 socket can be done. Here it turns out to be

00253 advantageous that the ejector from a flexible

00254 plastic part consists of an integrated, e.g.

00255 metallic pressing part. The latter can be

00256 ren execution also be a hard plastic part. 00257

Finally, the invention relates to a vacuum cleaner

00259 with a motor housing, possibly with an attached

00260 closed filter chamber, and a device handle, being

00261 the handle of the device in a socket close to the housing

00262 motor housing can be plugged in, with a mains socket,

00263 whereby the mains socket can be inserted into the handle

00264 is. Here is to improve the vacuum cleaner

00265 suggest that the handle of the device has a connector on one side

00266 for interaction with the mains socket,

00267 the plug in a socket receptacle of the device

00268 les by the dimension of the largest free cross section of the

00269 power socket is shifted back that the device handle

00270 is configured as a socket on the other side for

00271 effect with a compared to the handle side

00272 connector moved back by the same amount

00273 of the plug-in receptacle, the plug of the plug-in receptacle

00274 however at least partially from a hollow profile of the

00275 handle can be run over and the socket of the

00276 tool handle on the overrun dimension in the hollow profile

00277 is arranged moved back. Here comes

00278 pulls a power socket with at least two flat

00279 keraufnahmen to use, the power outlet in

00280 cross section perpendicular to the insertion direction out of round, with 00281 a symmetry extending through the largest dimension

00282 axis is formed. The training is concrete

00283 chosen that a division axis transverse to the axis of symmetry

00284 runs in such a way that the cross section above and below

00285 half the division axis of a convex Krürnrπungsli-

00286 is never limited, with both lines of curvature essentially

00287 are circular, with different

00288 radii. This results in a kind of elliptical

00289 ger cross section, preferably the transition areas

00290 of the two cross-sectional sections also rounded

00291 det are formed. An embodiment is preferred

00292 device, in which the radius of the above the division

00293 axis arranged cross-sectional section is larger

00294 as the radius below the division axis

00295 line of curvature. E.g. can the radius of the

00296 ren convex line of curvature 45 to 55 mm, preferred

00297 50 mm and the lower Krürriπungslinie a radius of 35

00298 to 40 mm, preferably 37 mm. It is essential

00299 that the center point of the radius of curvature

00300 outside the total cross section of the mains socket

00301 is arranged and the center of the smaller radius

00302 KrürruTiungslinie lies within the total cross-section,

00303 where both centers on the axis of symmetry of the

00304 mains socket are positioned. There is also further

00305 the possibility of the two above and below the

00306 dividing axis extending curvature lines each

00307 several circular sections of different radii

00308 to assemble. This results in a manageable

00309 practice-friendly design of the power outlet.

00310 In particular, this embodiment proves to be

00311 friendly. This is also a visual aid

00312 for the user, the socket in the correct position

00313 to be assigned plugs through which asyrπmetri-

00314 see given non-circular design of the cross section.

00315 In an advantageous development of the invention 00316 object is provided that one by the two

00317 transition areas of the different circular lines

00318 given cross-sectional dimension is significantly larger than

00319 a perpendicular largest dimension of the cross-sectional

00320 tes. This results in a relatively flat construction

00321 se the mains socket. Together with the circular section

00322 shaped cross-sectional sections above

00323 and below the division axis there is an ergonomic

00324 mix favorable design. Are preferred here

00325 ratios of 15:10 to 20:10, preferred

00326 17:10. In a preferred embodiment, one is

00327 largest cross-sectional dimension of approximately 34 mm and one

00328 for this vertical dimension of approx. 20 mm

00329 provided. It is also proposed that the insertion lengths

00330 ge of the mains socket into the device

00331 term plug-in receptacle about the largest cross-sectional

00332 solution to the mains socket. This means

00333 has an aspect ratio of the largest cross-sectional dimension

00334 solution for insertion length of approx. 1: 1. Furthermore, in

00335 suggestion that the tab receptacles in

00336 reference to a connecting line between the transition

00337 areas asymmetrically, namely to the cross-section

00338 cut with the more curved outline,

00339 are offset. As already indicated, the network

00340 socket - related to the connecting line between

00341 the transition areas - asymmetrical, but related

00342 on the axis perpendicular to this line

00343 symmetrical. The result of this is that at

00344 a symmetrical arrangement of the tab receptacles

00345 to the perpendicular to the connecting line between the

00346 transition areas extending axis and a -bezo-

00347 centered on the total cross section of the mains socket

00348 aligned arrangement the tab receptacles

00349 -related to the connecting line- asymmetrically

00350 are classified. In the preferred embodiment of the network 00351 socket, at which above and below this

00352 connecting line the cross section limited curvature

00353 nien different radii are provided, are the

00354 tab receptacles in the direction of the more

00355 curved outline, i.e. H. more in the area of small

00356 cross section having a smaller radius

00357 sets. It is preferred here that the flat plug receptacle

00358 parallel to the connecting line between the

00359 to shift corridors such that a connection

00360 line between the centers of the flat connector

00361 recordings at least approximately due to the area

00362 point of the entire cross section of the socket runs,

00363 the latter - due to the composition of the

00364 cross-section from lines of curvature different

00365 radii - not with the intersection of the connecting line

00366 between the two transition areas and this

00367 vertical axis coincides. The flat

00368 plug receptacles are otherwise those in the state of the

00369 technology based on known recordings. You point

00370 each have a rectangular entry cross section

00371 hand up. In the longitudinal direction of the mains socket

00372 extending opening is an electrical

00373 Connection-forming, metallic clamping sleeve provided.

00374 According to the invention it is further proposed that the

00375 mains socket protrude beyond its outer surface

00376 has the locking pin, which is perpendicular to the first

00377 stretching the tab receptacles is resilient. loading

00378 is essential due to this design, a pull-out

00379 tion of the connector. With an insertion

00380 ken the power socket into a device and / or

00381 stem-side, appropriately trained plug-in receptacle

00382 the locking pin enters a locking recess. This

00383 latching can only be unlocked, which is why

00384 area of the plug-in receptacle a corresponding button

00385 ment provided in the form of an ejector or the like 00386 hen can be. This is particularly the case with vacuum cleaners from

00387 advantage, because it is due to tensile loads

00388 the mains socket to unintentionally disconnect the plug

00389 connection can come. It is also proposed that

00390 the locking pin on the less curved outside

00391 is arranged. It proves to be particularly advantageous

00392 here that the locking pin is approximately in the middle of the

00393 flat connector receptacles is aligned. At a

00394 preferred embodiment, in which the weaker

00395 curved outline of the socket cross section

00396 forms the upper area of the power socket, results

00397 the advantage that when gripping the power outlet

00398 the locking pin sits ergonomically, so that this

00399 in the simplest way by means of the thumb for insertion

00400 the mains socket into a device-side and / or stick

00401 side receptacle can be depressed. It

00402 there is also the possibility of the device side

00403 and / or stem-side plug-in with a locking

00404 pin assigned to bevel, which

00405 when the mains socket is inserted

00406 of the locking pin. An embodiment is preferred

00407 device, in which cross-sectionally between the two

00408 flat plug receptacles a non-conductive round plug

00409 recording is formed. The round connector thus formed

00410 recording is therefore a blind recording without con-

00411 clock sleeve formed. The socket in the engine

00412 housing is the socket holder of the handle in the

00413 modeled essentially. Only the cross section

00414 of the plug arranged in the plug receptacle

00415 reduced in cross section so that between the plug

00416 and the inner wall of the plug-in receptacle

00417 remains. For this purpose, the connector on the housing is on one

00418 plug base arranged and cantilevered freely in the interior

00419 in the plug receptacle. In the so educated

00420 annulus occurs when inserting the tool handle 00421 a hollow profile of the same, which hollow profile in

00422 Extension of the socket on the device side arranged

00423 is net. This socket on the side of the device is

00424 cut adapted to the housing-side connector. The

00425 training is also chosen so that the power plug

00426 can both in the can holder of the handle

00427 can also be used in the plug socket of the motor housing

00428, i. H. Can holder of the handle and plug

00429 Name of the motor housing are the same in cross section

00430 trained. The length of the mains socket is

00431 chooses that when it is inserted into the plug

00432 do not take the motor housing in between

00433 plug and plug-in receptacle inner wall formed annulus

00434 entry. The can holder of the handle and the

00435 plug-in receptacle of the motor housing have a

00436 Socket and appliance handle end section cross section

00437 adapted internal cross section. Conditional on this

00438 configuration, the plug-in receptacles receive an introduction

00439 serfunction for the mains socket or for the device

00440 stem end section. With a slightly twisted attachment

00441 effect the power socket on the plug receptacle

00442 the convex curvature lines a reeving of the network

00443 socket in the socket. The power socket will

00444 automatically move to the desired insertion position

00445 device. It also follows from the geometries that despite

00446 only slight asymmetry a significant blocking

00447 incorrect handling is given. For example, if the network

00448 socket in a position rotated by 180 °

00449 plug receptacle fed, so it is not a plug

00450 possible. Here comes the referring function

00451 on the receptacle not applicable. The user

00452 cannot use the clutch either

Teach 00453 so that malfunctions are counteracted. 00454 00455 Due to the previously described configurations

00456 is the simplest vacuum cleaner according to the invention

00457 way for both floor and above-ground processing

00458 device usable, using only one connecting cable

00459 finds. The latter is only from an upper device

00460 testielend in a plug-in receptacle of the motor housing

00461 repositioned. The plug receptacle fulfills the

00462 tasks of a good transmission of high mechanical

00463 loads between handle and motor housing,

00464 a coding of the mains cable or mains socket and

00465 handle, an electrical contact of devices

00466 testiel and motor housing as well as a simple plug and

00467 Removal possibility for tool handle and mains socket.

00468 To be able to transmit the forces and moments, dives

00469 the handle, which is preferred as an aluminum

00470 profile tube is made, preferably at least 80 mm

00471 into the socket. The detection of whether a device

00472 handle or a mains socket is for the

00473 Function of electronics in the vacuum cleaner mandatory

00474 like this. If the handle is inserted, the

00475 electronics the potentiome integrated in the handle

00476 ter / switch module as setpoint generator and as mains

00477 switch. If the mains socket is plugged in, however, the following applies

00478 a potentiometer / switch mounted in the basic device

00479 module as setpoint generator and as mains switch. To the

00480 Power cable connection in the upper end of the handle

00481 contrary to the handle connection only the requirements

00482 after an electrical contact and a simple

00483 Chen plugged and removed. Height

00484 mechanical forces do not occur here. A plug

00485 length of, for example, 80 mm also comes in at this point

00486 generally out of the question for reasons of space. Out of this

00487 results that the outer profile of the handle and

00488 the mains socket is identical, that the detent from

00489 equipment handle tube and power socket is identical and that 00490 a coding of the handle and mains socket

00491 lies. It also follows that the insertion length of the

00492 device handle preferably at least 80 mm and the plug

00493 length of the mains socket is preferably a maximum of 35 mm

00494 carries. The last two dimensions contradict

00495 appear to be, but can be inventively

00496 agree with each other, since the electrical contact

00497 ation within 35 mm behind the insertion opening

00498 takes place, but the device tube is inserted by 80 mm

00499 must be used. This measure will simultaneously

00500 in an elegant way the coding of the handle and

00501 mains socket enables. It can also ensure this

00502 will be that either handle as well as

00503 mains socket can be plugged into the motor housing

00504 NEN, but that excludes in the upper end of the handle

00505 lent the power socket is pluggable. Due to the special

00506 le contour of tool handle and mains socket is

00507 ensures that the use of network cables

00508 gen, the high number of bending cycles and loads,

00509 that occur when operating a vacuum cleaner, not

00510 withstand, is excluded. It turns out further

00511 is advantageous in that the device arranged in the basic device

00512 potentiometer / switch module with device

00513 stalk is brought into a position in which the

00514 switch is turned on. This is required

00515 since the circuit breakers in the device handle and in the motor

00516 houses are arranged in series. In the invention

00517 the circuit breaker in the

00518 motor housing through the device inserted by 80 mm

00519 stem tube pushed into its maximum position. To at

00520 a conversion to an above-ground operation is not that

00521 entire device with plugging in the mains socket

00522 must be opened when removing the handle

00523 this switch is pulled back into its off position

00524 gene. For this purpose there is a coupling between 00525 hen the circuit breaker and the device stem tube 00526 hen. 00527 00528 The invention is explained below with reference to the drawing, 00529, which merely represents an exemplary embodiment, 00530. 00531 00532, FIG. 1 shows a perspective illustration of a vacuum cleaner according to the invention with a motor housing 00534 and a connected filter chamber, 00535 whereby a device handle is inserted into a 00536 plug-in receptacle and a power socket is inserted into the 00537 device handle; 00538 00539 FIG. 2 shows a representation corresponding to FIG. 1, 00540 but after the appliance handle has been removed from the 00541 motor housing and the mains socket from the appliance 00542 handle; 00543 00544 FIG. 3 shows another illustration corresponding to FIG. 1, but omitting the device 00546 les, here the power socket being plugged directly into 00547 the plug-in receptacle of the motor housing 00548; 00549 00550 FIG. 4 shows an enlarged detailed illustration from 00551 FIG. 2, showing the plug receptacle close to the housing; 00552 00553 Fig. 5 is an end view of the plug-in close to 00554; 00555 00556 FIG. 6 shows a further perspective detailed illustration 00557 of a 00558 device handle end section corresponding to the plug-in receptacle, partially broken open 00559 chen; 00560 FIG. 7 shows a further perspective detailed illustration

The motor housing G has a 00622 bracket 20 with a plug receptacle 21. In this 00623 plug receptacle 21 is a preferred as Aluminum tube 00624 trained handle St inserted. The latter 00625 has a handle 22 on its end region facing away from the motor housing G. The electrical connection is made in 00627 via a connecting line 2, which 00628 ends a conventional electrical plug and the other ends 00629 a mains socket designed as a power connector O 97/32511 PCΪ7EP97 / 01054

00630 N. This mains socket N is inserted with reference to 00631 FIG. 1 into a socket receptacle 9 on the handle side, assigned to the area of the 00632 handle 22. 00633 00634 Both the handle St and the motor housing G each 00635 have a circuit breaker 23, 24 designed as a potentiometer / switch module. These circuit breakers 23, 24 are designed as slide switches 00638, circuit breaker 23 being positioned in the area of handle 00639 fixed 22 and circuit breaker 24 being in the area of bracket 00640 20 of motor housing G. 00641 00642 According to the invention, the design is selected so that 00643 both the power plug N from the handle St and 00644 the handle St from the motor housing G can be separated. 00645 This is shown, for example, in FIG. 2. This gives 00646 the possibility of connecting the mains socket N directly to the motor housing 00648 via the plug-in receptacle 21 while leaving the device stem 00647. Such a configuration is shown in FIG. 3. 00650 results in a design that is easy to handle for 00651 use of the vacuum cleaner 1 for above-ground work. 00652 00653 With reference to FIGS. 7 to 14, the 00654 mains socket N and the socket receptacle 9 are described in more detail below. 00656 00657 The mains socket N is non-circular in cross section perpendicular to 00658 with an insertion direction r, with a 00659 symmetry axis 00660 x running through the largest dimension. As can be seen from FIG. 10, the mains 00661 socket N essentially consists of two areas arranged one behind the other 00662. On the one hand, 00663 is a plug-in area A, which has a division axis y running transverse to the 00664 axis of symmetry x, 00665 whereby the cross section into an upper and a lower

00666 divided area, whereby both areas are different

00667 have different area dimensions. The second

00668 section of the mains socket N connects to the

00669 first section A and forms a connection

00670 cut out B. At this connection section B is the

00671 mentioned connecting line 2 arranged, in which

00672 section B a usual train security not shown

00673 tion for line 2 is available. Area B

00674 is in the form of a truncated pyramid and

00675 has ribs 4 on the outside for improved handling

00676 availability. 00677

00678 The cross section of the insertion area A is above

00679 and below the division axis y of one each

00680 convex Krürtiriungslinie Kl and K2 limited, both

00681 curvature lines Kl and K2 essentially circular

00682 are sectional. The above the division axis y

00683 running curvature line Kl is less strong

00684 curved than that below the division axis y

00685 end curvature line K2, which means that the radius

00686 the upper KrürruTiungslinie Kl is greater than the radius

00687 of the lower curve K2. In the transition areas

00688 Chen U between the different lines of curvature

00689 Kl and K2 is a soft transition in form

00690 provided a rounded connecting line. A

00691 connecting line between these transition areas U

00692 forms the division axis y already mentioned. 00693

00694 The flat plug receptacles 6 open in the area of the socket

00695 end face 5 and are rectangular in cross section.

00696 forms. The longer side of the rectangular cross

00697 section aligned parallel to the axis of symmetry x

00698 with a length / width ratio of approx. 15:10

00699 or from approx.8.5 to 5.5 mm. Parallel to the extension 00700 of the division axis y, the two flat plug receptacles 00701 with a dimension of approximately 9 mm are spaced from one another, with a symmetrical arrangement with the axis 00703 x. 00704 00705 As can be seen from FIG. 9, the flat plug receptacles 00706 are asymmetrical with respect to the division axis y, namely 00707 towards the cross-sectional section with the more 00708 curved outer line K2, offset such that a 00709 parallel to the division axis y running center axis 00710 of the two tab receptacles 6 runs approximately through the surface center F 00711. 00712 00713 The circular connector receptacle 7 is arranged in cross-section between 00714's two connector receptacles 6 and 00715 has a circular cross-section. The arrangement 00716 is made such that an axis of symmetry of the 00717 circular connector receptacle 7 is congruent with the symmetry 00718 axis x of the mains socket N and the axis of symmetry of the circular connector 00720 kerchief 7 running perpendicular to this axis is almost in height with the lower edges of the 00721 flat connector receptacles 6 is aligned. 00722 00723 The flat plug receptacles 6 have internally arranged 00724 ned, electrically conductive ferrules 8 to which 00725 the individual wires of line 2 are connected at the rear 00726 sen. The circular connector receptacle 7 is designed as a blind receptacle, ie non-conductive. 00728 00729 In the exemplary embodiment shown, the radius R1 00730 of the line of curvature Kl is approx. 50 mm and the radius R2 00731 of the line of curvature K2 is approx. 37 mm (see 00732 FIG. 9). The transition areas U between the curvature lines K1 and K2 are also formed in the manner of a circular section 00734. 00735 Furthermore, it follows from these dimensions that the geometrical center 00736 of the curvature line K1 lies outside the 00737 total cross section of the mains socket N, whereas 00738 the geometric center M2 of the curvature line 00739 K2 is arranged within the overall cross section. 00740 Both geometric centers Ml and M2 are aligned on the 00741 axis of symmetry x. 00742 00743 Due to the asymmetrical design of the cross section 00745, which is intended perpendicular to the axis of symmetry x 00744, a surface center point F results which does not coincide with 00746 the intersection of the axis of symmetry x and the division axis 00747 y. It is rather the case that this surface center F - based on FIG. 9 - is formed below the 00749 division axis y, ie offset in the direction of the 00750 more curved line of curvature K2. 00751 00752 From the geometric dimensions described, 00753, based on the cross section, results in a width / height ratio of approx. 17:10. Based on the exemplary embodiment, a result is given by the two transition ranges 00756 che U. Cross-sectional dimension b of approx. 34 mm 00757 and a perpendicular largest dimension c of approx. 00758 20 mm. 00759 00760 As can further be seen from FIG. 11, the insertion area A is dimensioned such that the length 11 of the insertion area 00762 corresponds approximately to the cross-sectional width dimension b 00763. 00764 00765 Furthermore, the mains socket N has a locking cam 18 protruding beyond the 00766 outer surface, which 00767 is resilient perpendicular to the extension of the flat plug receptacles 00768 6. Specifically, the arrangement is made so that 00769 that the locking cam 18 on the by 00770 Krürnrπungslinie Kl described upper outer surface of 00771 insertion area A is arranged, with central Aus¬ 00772 direction to the flat plug receptacles 6. Furthermore 00773 the position is selected so that the locking cam 18 about 00774 in the middle of the longitudinal extent 11 of the insertion area A 00775 00776 this locking cam 18th can be moved against a pressure spring 19 arranged in the insertion area 00777 such that the locking cam 18 is completely immersed in the outer wall 00779 of the insertion area A. 00780 00781 The positioning of the locking cam 18 on the top 00782 of the insertion area A and the approximately central positioning 00783 there offers the ergonomic advantage of 00784 simply pressing down the locking cam 18 by means of 00785 thumb pressure. 00786 00787 The socket receptacle 9 on the handle side essentially consists of a housing 13 and a plug 14 embedded in this 00789 housing 13. This 00790 connector 14 is relocated to a front edge of the 00792 housing 13 facing the outer wall 00791 of the socket receptacle 9, so that a cavity is formed in front of the connector 00793 ker 14. In this cavity 00794, tabs 12 00795 arranged on the connector 14 protrude, the length of these tabs 12 being smaller 00796 than the 00797 depth of the cavity measured in the same direction. The tabs 12 are electrically conductive and are connected at the rear in the area of the connector 00799 14 with corresponding connecting lines. 00800 00801 As can be seen in particular from FIG. 12, the 00802 socket receptacle 9, in particular its housing 13, has a 00803 cross section which corresponds to that of the mains socket N 00804. The inner wall line of the cross-section 00805 tes of the housing 13 corresponds to the outer line 00806 of the mains socket N. The corresponding 00807 radii and clear dimensions of the housing 13 are chosen somewhat 00808 larger than that of the mains socket N, so that 00809 the latter without problems in the socket receptacle 9 or in 00810 the cavity 11 can be performed. 00811 00812 In the case of the can receptacle 9 too, the cross section 00813 is composed of a cross-sectional section arranged above and below a dividing axis y '. 00815 The upper area is delimited by a convex curve line K3 and the lower section by a curve line K4. Here, too, the radius of the 00818 upper curve K3 is larger than that of the 00819 lower line K4. 00820 00821 It can also be seen that both in the mains plug 00822 se N and in the socket receptacle 9, the dimension between 00823 between the two transition areas U is significantly 00824 larger than the perpendicular largest dimension 00825 of the cross section. 00826 00827 The flat plugs 12 already mentioned are arranged on 00828 the plug 14 in such a way that when the 00829 mains socket N is inserted into the socket receptacle 9, the flat plugs 00830 12 the flat plug receptacles 6 pass through into the 00831 clamping sleeves 8 to form a coupling. It can also be seen from FIGS. 13 and 14 that 00833 the length 11 of the insertion area A measured in the insertion direction r corresponds to the 00835 depth 12 of the socket receptacle 9 measured in the same direction, so that after 00836 the mains socket N is plugged in the Dosenaufnah¬ 00837 me 9 only the connection area B of the power outlet N 00838 emerges from the can receptacle 9. This results in 00839 further functions of the two areas A and B. 00840 Area A is the actual coupling area for 00841 to achieve a connector. Area B is 00842 as the handling area, in which area the 00843 socket N is detected for insertion into or execution from the socket receptacle 9. 00845 00846 The socket receptacle 9 has in the area of its housing 13 00847 a locking cam during the insertion process 18 of the 00848 socket N against the compression spring 19 relocating 00849 bevel 25. 00850 00851 The locking cam 18 takes place in the coupling position according to 00852. FIG. 14 is received in a housing-side bore 26 00853 of the socket receptacle 9. The locking cam 18 displaced by the compression spring 19 in 00854 prevents 00855 an unwanted removal of the mains plug N from the 00856 socket receptacle 9. 00857 00858 The release of this clutch is only possible with emphasis on 00859. For this purpose, the can receptacle 9 has a key element 00860 27. The latter is integrally formed on the housing 13 in the region of the insertion side on the upper, less curved 00862 outer surface formed by the line of curvature K3. The transition area between housing 00864 se 13 and sensing element 27 is designed to be resilient in the case of a one-piece design, for example by material thinning in the transition area. On the inside, the 00867 push-button element 27 is formed with a release finger 00869 28 pointing downwards, ie in the direction of 00868 the bore 26 of the housing 13. 00870 00871 To release the plug connection, the pushbutton 27 00872 is pressed in, so that the pushbutton 00873 27 together with the disengaging finger 28 is tilted, the 00874 free end of the disengaging finger 28 being the latching cam 18th 00875 against the spring force of the compression spring 19 moved back 00876 that the locking cam 18 comes out of the area of 00877 housing bore 26. The 00878 mains socket N can then be removed. 00879 00880 This designing trigger protection is particularly desired 00881 for vacuum cleaners, since here the 00883 mains socket N could be unintentionally pulled off with a plug device without locking during operation, 00884, which is not desirable for safety reasons. 00885 00886 The bracket 20 of the 00887 motor housing G which has the plug-in receptacle 21 is tubular. The plug 00888 receptacle 21 is positioned in a freely projecting 00889 end region of the arm 20, a 00890 muzzle cross section of the plug receptacle 21 corresponding to the muzzle cross section 00891 of the can receptacle 9 (cf. 00892 in this respect FIGS. 5 and 12). It follows from this, 00893 that the inner-walled line profile of the cross section 00894 of the plug receptacle 21 corresponds to that of the outer line profile 00895 of the power socket N, the radii and 00896 clear dimensions of the plug receptacle 21 being chosen slightly larger than that of the power socket N, so that the latter without 00898 problems in the receptacle 21 can be performed. 00899 00900 Also in the plug receptacle 21, the cross section 00901 is composed of a cross-sectional section 00903 arranged above and below a 00902 division axis y ¹ '. The upper area is bounded by a 00904 convex curve K5 and the lower section by 00905 a curve K6. Here, too, the 00906 radius of the upper line of curvature K5 is larger than 00907 of the lower line K6. 00908 00909 Specifically, this means that the radius R5 describing the upper curvature line 00910 K5 essentially corresponds to the radius 00911 R1 and the lower 00912 radius R6 describing the curvature line K6 corresponds essentially to the radius R2 of the mains socket N 00913 chen. 00914 00915 The plug 29 arranged in the plug-in receptacle 21 is fastened in the plug-in receptacle 21 00916 00916 via a plug base 30. The plug base 30 has a cross-section 00918 which corresponds to the hollow profile cross-section of the 00919 bracket 20 or the plug-in receptacle 21. The 00920 plug base 30 is held in a precise fit in the plug receptacle 21 00921 and, for example, is adhesively bonded to the inner wall of the bracket 00922 20. 00923 00924 The connector 29 assigned to the connector base 30 protrudes 00925 from the base 30 freely into the space of the connector 00926 receptacle 21, for which purpose the connector 29 is cross-sectionally reduced in relation to the connector base 30 or the inner wall 00928 of the connector receptacle 21. Here, too, 00929 results in a cross section composed essentially of an upper crimping area 00930 K7 and a lower crimping area K8 00931, the dimensions and radii 00932 being directly related to those of the plug 00933 receptacle 21. 00934 00935 Due to the cantilevered design of the plug 00936 core 29, there is an annular space 00938 between the plug-in interior 00937 wall 31 and the outer wall of the plug 29. In the exemplary embodiment 00939 shown, there is a distance between the plug-in inner wall 31 00940 and connector 29 approx. 3 mm. 00941 00942 The connector 29 and the connector base 30 are preferably 00943 connected to one another in the same material. On the 00944 free end 33 of the plug 29 are flat plugs 00945 34 cantilevered in the plug-in space 21 positio¬ 00946 niert. The latter are arranged according to the flat plug receptacles 00947 6 of the mains socket N on the end face 33 00948. As can be seen from FIG. 5, a round plug 35 is provided in the middle 00949 between the flat plugs 34, the lower region of curvature K8, 00950, 00951, which also protrudes into the plug-in space 21 00952. 00953 00954 This circular plug 35 is used when the device 00955 stem St is inserted for signal transmission of the circuit breaker 23 arranged in the stem 00956 St or in its handle 22. 00957 00958 00959 Both the flat plug 34 and the round plug 35 00960 are electrically conductive and rearward in the area of the 00961 connector 29 or the connector base 30 with 00962 corresponding to the connecting lines 36, which lead inside the motor housing 00963 G to electronics or the like, 00964. 00965 00966 The positioning of connector 29 and connector base 30 00967 is selected so that a distance 13, measured from 00968 of the end face 33 to the mouth 37 of the plug socket 00969 21, is set, which corresponds to the length dimension 11 of section 00970 A of the mains socket N. . In the 00971 exemplary embodiment shown, a dimension 13 of 35 mm is selected in accordance with the 00972 N mains socket. 00973 also results from the fact that dimension 13 of plug receptacle 21 is equal to 00974 dimension 12 of socket receptacle 9. 00975 00976 Furthermore, the arrangement is such that the flat connector 00977 34 and the circular connector 35 are at a distance from the 00978 mouth 37 ends. This also applies to the flat plug 00979 12 in the receptacle receptacle 9. 00980 00981 The total length 14 is calculated from the addition 00982 of the first free length 13 and the length 15 of the cantilevered section of the plug 29, measured from the root 00984 area 38 to the end face 33 (cf. 00985 Fig. 15). An embodiment is preferred here, at 00986 which, as shown, corresponds to dimension 14 at least twice 00987 th of dimension 13. In the embodiment shown, the dimension 14 measures 80 mm, which results in a 00989 cantilevered length 15 of the plug 29 of preferably 00990 45 mm. 00991 00992 In the free areas between the mouth 37 and the end face 00993 of the plug 29, the plug receptacle 21 00994 has a receptacle 39 into which, for example, the Rastnok- 00995 ken 18 of the power outlet N can snap into place. This locking device 00996 is provided with an ejector 40 for disengaging 00997 a locking pin 00998 entering the locking device 39. The ejector 40 consists of a flexible 00999 plastic part 41 with an integrated metallic 01000 pressing part 42, which projects into the snap-in receptacle 39 01001. This pressing part 42 can also consist of hard plastic 01002. The flexible plastic part 41 is held in the region of the locking receptacle 39, so that by simply pressing this plastic part 41, the pressing part 01005 42 is displaced such that a locking cam lying in this locking receptacle 39 moves 39 out of the receptacle 01007 becomes the release of the catch. 01008 01009 As already mentioned, a circuit breaker 24 is arranged in the arm 20 of the motor housing 01010 G, which is designed as a slide switch 01011. 15 through 24 are shown in the sectional views 01013 only the slide actuation handle 43 of the circuit breaker 01014 is shown, ie omitting 01015 the potentiometer 01016 / switch module to be actuated by the handle 43. However, the handle 43 is connected to this module in a known manner in 01017, so that 01018 sliding movements of the handle 43 are transmitted directly to the module 01019 for switching and controlling the engine speeds 01020. 01021 01022 The slide actuation handle 43 is exposed in a longitudinal slot 01023 44 of the wall of the arm 20. The 01024 handle 43 passes through this longitudinal slot 44 with a 01025 protrusion for securely gripping the handle 43. 01026 on the underside, ie the inside of the outer jacket wall, 01027 the actuating handle 43 has a rosette-like collar 01028 45, the width of which, measured transversely to the longitudinal extension 01029 of the bracket 20, is chosen to be larger is the width of the longitudinal slot 44 measured in the same direction. 01030. The length of the collar 45, measured in the longitudinal extent 01032 of the arm 20, corresponds approximately to 1.5 times the length of the longitudinal slot 01034 44 measured in the same direction in 01033. wherein a length of 01035 handle 43 measured in the same direction corresponds to approximately half the longitudinal slit length 01036. Thus, over the entire displacement path of the 01037 handle 43 or the circuit breaker 24, there is an underside of the longitudinal slot 44 on the 0103838 side, 01039, for example, for the dust-protected position of the components arranged under the longitudinal slot 4440, such as the Poten¬ 01041 tiometer / switch module. 01042 01043 This results in a displacement of the handle 43 01044 or the circuit breaker 24 of approx. 20 to 25 mm. 01045 01046 In a basic position according to FIG. 15, 01047 extends an upper width edge 46 of the collar 45 at the height 01048 of a rear of the connector 47. 01049 01050 Furthermore, the circuit breaker 24 or its 01051 slide actuation handle 43 has a remote actuation 01052 extension 48, which is , starting from an underside 01053 of an area of the collar 01054 45 facing away from the plug 29, extends in a basic position according to FIGS. 15 to 01055 to the end face 33 of the plug 29. 01056 01057 In concrete terms, the design of the remote control extension 01058 48 is selected such that a section starting from 01059 the underside of the collar 45, including an acute 01060 angle to it, extends into the area of the 01061 upper width edge 46 of the collar 45 extends. This section of the section 01062 is identified in the drawings with the number 01063 number 49 and is designed as a rigid section 01064, with side walls which are supported on the 01065 underside of the collar 45 or are connected to this 01066 in the same material. On the end region 01068 of the section 49 facing the upper 01067 width edge 46 of the collar 45, a stop 50 is formed which is oriented perpendicular to the collar 45 01069 and extends from 01070 the free end of the section 49 to the underside 01071 of the collar 45. 01072 01073 In the area of the transition from the stop 50 to the collar 45 01074, a second section 51 of the remote actuating extension 48, which projects freely in the direction of the plug-in receptacle 01015 me 21, is formed on the stop 50. As a result of this free-standing configuration of the second section 51, 01078 has the possibility of resilient evasion 01079. At its free end 52, the remote actuation extension 80 or its second section 51 has one 01081 latching formation 53, which is formed in the form of a 01083 nose-like elevation facing downwards, ie 01082 facing away from the plug-in inner wall 31. 01084 01085 The cantilevered portion 51 of the extension actuation 01086 set 48 lies at least in the area of the latching formation 01087 53 in the annular space 32 formed between the plug 29 and the plug-in receptacle interior 01088 31. For the 01089 passage of the plug base area, the plug 01090 core base 30 has a groove 54 which is open towards the plug receptacle inner wall 31 and has side walls which at the same time cause the section 51 to be guided laterally. 01093 01094 Corresponding to the socket receptacle 9, the plug-in 01095 receptacle 21 also has a run-up bevel 01097 55 which is displaced by a detent during a plug-in operation 01096 cam against a spring. 01098 01099 In the free end region of the handle St, which is shown in FIG. 6 and faces away from the handle 22 and which, as already mentioned, is tubular, 01102 a distance 16 to the mouth 56 is a socket 57 posi¬ 01103 . The latter is, for example, adhesive-bonded to the inside of the tubular article handle St. 01105 01106 The socket 57 has, corresponding to the mains socket N 01107, two flat plug receptacles 58 and a round plug 01109 arranged between these 01108 two flat plug receptacles 58 59. Contrary to the mains socket N in OHIO this socket 57, all three receptacles 58 and 59 are connected and the back of the socket 57 is connected to a connecting line 60 running in the 01112 handle St, 01113. The two wires of the flat plug receptacles 01114 58 are connected at the other end to the flat plugs 12 of the receptacle-side plug 14. The round 01116 plug receptacle 59 connected wire leads to the power switch 23 arranged in 01117 the handle 22. 01118 These connections are not shown in detail. 01119 01120 The dimension 16 by which the socket 57 is moved back in relation to the 01121 mouth 56 in the device handle St, 01122 corresponds to the dimension 15 of the cantilevered plug 29 in 01123 of the plug receptacle 21 or the length of the plug 29 and plug receptacle 01124 Inner wall 31 formed free 01125 space 32. 01126 01127 The cross-sectional area of the 01128 hollow profile 61 formed on the length 16 is adapted to the 01129 of the mains socket N in the area of its outer contour. A curvature line K9 running above a 01130 dividing line y ¹ '' corresponds in its design to the curvature line K 1 of the 01132 mains socket N and thus essentially also to the 01133 curvature line K5 in the region of the plug-in receptacle 21. The 01134 below the dividing line y ''' running Krüirατtungs- 01135 line K10 therefore corresponds to the Krürnrnungslinie K2 the 01136 power socket N and also essentially the Krürnrnungs¬ 01137 line K6 in the area of the plug-in receptacle 21. 01138 01139 The wall thickness of the hollow profile 61 is 01140 the width of the free space 32 in the plug-in receptacle 21 01141 selected. In the exemplary embodiment shown, the hollow profile 61 has a wall thickness of approximately 3 mm 01143. This results in inner curvature lines K1 and 01144 K12, which essentially correspond to the curvature lines K7 and 01145 K8 of the outer contour of the plug 29. 01146 01147 Furthermore, the design is selected such that the length 16 01148 of the hollow profile 61 corresponds approximately to 2.3 times the largest free dimension of the tool handle cross section, 01150 which largest free dimension is equivalent to dimension b of the mains socket N 01151. 01152 01153 Approximately at the level of the socket 57, the device handle 01154 St has a locking cam 01155 62 which projects beyond the outer surface and which is resilient in accordance with the power plug socket 01156 to extend the tab receptacles 58 of the plug 01157 socket 57. This locking cam 62 is shown in 01158 FIGS. 17 to 22. 01159 01160 On the outer surface of the hollow profile 61 described by the curvature line K9, on which the locking cam 62 is also arranged 01162, the hollow profile 01163 61 has a locking recess 01164 63 positioned near the mouth 56. 01165 01166 If the handle St with its socket-side 01167 free end is inserted into the plug-in receptacle 21, 01168 first acts on the hollow profile wall on the 01169 side in the area of the mouth 56 in the area of the mouth 56 of the free end 52 of the remote control extension 48, which is initially at the level of the 01171 plug end face 33 is positioned. The flat plug 01172 ker 34 and the round plug 35 are still freely in this position 01173 in the hollow profile 61 of the handle St 01174. This position is shown in FIGS. 17 and 18. A further displacement of the tool handle St 01176 in the direction of the arrow r initially causes the resilient end 52 of the remote control device 01178 zes 48 to be deflected in such a way that, in the further course of the insertion of the tool handle 01179, the catch formation 53 into the catch recess 01180 63 entry. This has the consequence that when the tool handle St is shifted further in the direction r 01182 to reach the end position according to FIGS. 19 and 20 01183, the remote control extension 48 is dragged along with the catch 01184, which shifts the power 01185 switch 24 or its slide actuation handle 43 01186 in a maximum position. In the course of this 01187 insertion, the device handle St passes over the plug 29 of the plug-in socket 01189 21 in the area 01188 of its hollow profile 61, by immersing the hollow profile wall in the free space 32 01190. Due to the length 01191 described above, in an end position according to 01192 FIGS. 19 and 20, the device handle St is supported on the one hand in the area 01193 of its mouth-side end face on the plug socket 30 and on the other hand in the area of its socket area on the end face 33 on the plug side. The 01196 flat plugs 34 and the round plug 35 find receptacle 01197 in the flat plug receptacles 58 and the round plug receptacle 01198 59 of the socket 57 for coupling the electrical 01199 lines. 01200 01201 In the end position, the latching cam 62 of the device 01202 handle St engages in the latching receptacle 39 of the plug receptacle 01203 21. A cancellation of this latching is only possible with emphasis on the lens, in that the ejector 40 is actuated in such a way that the pressing part 42 embedded in the flexible plastic part 41 01206 moves the locking cam 62 back against the spring force 01207. 01208 01209 The power connection is made via the coupling of the power socket 01210 and socket receptacle 9 according to FIG. 14. In 01211 of such a configuration, which is shown in FIG. 1 as a whole, the vacuum cleaner 1 is a handheld device 01213 for Tillage usable. The suction motor or its power control 01215 is switched on and off 01215 via the circuit breaker 23 in the handle 22. 01216 The 01217 circuit breaker 24 in the motor housing G connected in series with this circuit breaker 23 is shifted to a 01218 full load position. 01219 01220 To use vacuum cleaner 1 for above-ground work,

01221 the device handle St is removed from the motor housing G

01222 gen. This takes place when the

01223 equipment handle St in the direction of arrows r ¹ according to

01224 FIGS. 21 and 22 entrainment of the remote actuation

01225 set 48, due to the locking of force

01226 Ausformung 53 and rest exception 63. This dragging along

01227 is only ended as soon as the stop 50 of the remote

01228 extension 48 against the rear of the connector 47

01229 occurs. Thereafter, the detent formation 53 leaves conditionally

01230 by the resilient design of section 51, the

01231 latching exception 63. This position defines the exhibition

01232 circuit breaker 24. This ensures

01233 indicates that pulling the tool handle St off

01234 switching of the suction motor results. 01235

01236 After removing the device handle St, you can insert it

01237 of the mains socket N into the plug receptacles 21.

01238 This is shown in Figs. 23 and 24. Here is

01239 to recognize that the power socket N with their

01240 end face 5 on the end face 33 of the plug 29

01241 supports. Here too you will find the tabs 34 and

01242 round plug 35 their corresponding flat plug receptacle

01243 men 6 or round plug receptacle 7 in the mains socket

01244 N, whereby, as already mentioned, the round plug holder

01245 7 is only designed as a blind receptacle. loading

01246 is due to the fact that the mains socket N does not protrude

01247 of the hollow profile, which in the free space 32nd

01248 could occur, through the mains socket N the

01249 Remote control extension 48 neither acted on nor

01250 relocated. From this it follows that with such

01251 configuration, which is shown in its entirety in FIG.

01252 is, the circuit breaker 24 first in one

01253 Off position remains. A manual, operator-side

01254 Actuation of the circuit breaker 24 has no effect 01255 interfering with the area of the plug receptacle 21. The 01256 vacuum cleaner 1 is thus designed in the simplest manner for over-ground work, the power supply being carried out in a direct way. 01259 01260 As a result of the configurations 01261 described above, it is possible to insert the mains socket N both into the 01262 socket receptacle on the handle side and into the 01263 housing receptacle 21 for the power supply 01264. The device handle St, on the other hand, can only be inserted into 01265, the plug-in receptacles 21 of the motor housing G 01266. The hollow profile-like design of the 01267 handle end mechanically activates the circuit breaker 01269 required for the work corresponding to 01268. Furthermore, the design 01270 of the handle end means that high forces and moments can be transmitted from the 01271 handle St to the device housing G 01272. 01273 01274 All features disclosed are essential to the invention. 01275 In the disclosure of the application, the 01276 disclosure content of the associated / attached priority documents (copy of the prior application) is hereby fully incorporated, also for the purpose of including features of these 01279 documents in claims of the present application with 01280. 01281
