Arranged at least on one leg and on the vacuum cleaner housing at a distance from the locking elements are latching elements, which are able to be brought into engagement with one another by pivoting the gripping bar into its vertical position. - The documents WO 2018/057358 A1, CN 201847612 U, JP H0646974, WO 2010/092514 A1, EP 1656064 B1, US 2005/0257340 A1, U.S. Pat. No. 5,339,487 A and EP 0935944 A1 each disclose further vacuum cleaners with a vacuum cleaner housing, a gripping bar being pivotably mounted on the vacuum cleaner housing.
- US 2005/0050677 A1 discloses a vacuum cleaner with a suctioned material container, wherein the suctioned material container is releasably connected to a suction head of the vacuum cleaner and wherein the suctioned material container comprises a pivotably mounted gripping bar.
- Disclosed in EP 3448218 B1 is a vacuum cleaner comprising a container, a suction unit, an air channeling unit, and an exhaust air unit, wherein the exhaust air unit comprises a collection container defining a substantially annular air flow volume, which is concentric to the suction unit and which is positioned around one or more outlet openings of the suction unit in order to collect air and to conduct collected air to an outlet opening of the collection container. The exhaust air unit further comprises two opposing exhaust air channels, wherein each of the two channels surrounds a respective portion of the collection chamber and comprises an inlet end coinciding with the outlet opening of the collection container and a respective outlet end, which is opposed to the inlet end, in order to discharge air that is suctioned by the suction unit.
- U.S. Pat. No. 4,809,394, US 2002/0088103 A1, and DE 602 00 858 T2 also disclose vacuum cleaners.
- In accordance with an embodiment of the invention, a suction apparatus is provided, which is versatile while having a compact design and which is easily and comfortably operable. In accordance with an embodiment of the invention, provision is made in a suction apparatus that the suction apparatus comprises a pipe element with an adapter device, wherein the adapter device is fluidically releasably connectable or connected to a suction port of the suction apparatus for performing a suction operation and the adapter device is fluidically releasably connectable or connected to the first air outlet for performing a blowing operation, and wherein an air inlet opening of the second channel for supplying process air from the suction blower device to the second air outlet is closed by at least one wall element of the adapter device when the adapter device is properly connected to the first air outlet.
- As a result, a decoupling of process air through the second air outlet can be blocked or unblocked depending on whether the adapter device is connected to the first air outlet or not. Assuming the adapter device is properly connected to the first air outlet, the decoupling of the process air takes place, in particular, exclusively via the first air outlet, the process air then being decoupled from the suction head via the first air outlet, in particular, at an increased outflow speed and/or at an increased pressure. Thus, for example, an effective blowing function can be achieved on the suction apparatus.
- If the adapter device is separated from the first air outlet, the second air outlet is unblocked. The process air is then decoupled from the suction head both via the first air outlet and via the second air outlet. An air flow of the decoupled process air is thereby distributed to the first air outlet and the second air outlet, such that an outflow speed and/or a pressure of the decoupled process air is reduced at the first air outlet or at the second air outlet. An operator of the suction apparatus undesirably being blown on during operation is thereby minimized.
- The suction apparatus in accordance with the invention can thereby be used by an operator in a particularly versatile and comfortable manner.
- When the adapter device is separated from the first air outlet, the second channel is, in particular, completely unblocked and/or completely open. When the adapter device is properly connected to the first air outlet, the second channel is, in particular, completely blocked and/or completely closed so that, in particular, no process air is decoupleable by the second air outlet.
- In principle, it is also possible that an intermediate state is achievable using the adapter device, in which the air inlet opening of the second channel is at least partially unblocked and/or partially open.
- In principle, it is also possible that the air inlet opening of the second channel is able to be closed or unblocked by a nozzle element, wherein, for example, the nozzle element is arranged on the suction head or on the adapter device.
- It is further possible that the air inlet opening of the second channel is able to be closed or unblocked by arranging an accessory element of the suction apparatus within the first channel. For example, the accessory element is a nozzle element or a crevice nozzle for use with the suction apparatus, which is arrangeable within the first channel. When the accessory element is arranged within the first channel, the air inlet opening of the second channel is blocked by the accessory element.
- It may be favorable if the air inlet opening of the second channel is arranged in a transition region between a connecting channel of the channel device and the second channel, wherein process air from the suction blower device is suppliable to the first channel and/or the second channel by the connecting channel. The second channel can thereby be fluidically separated from the connecting channel in a technically simple manner.
- It may be favorable if the air inlet opening of the second channel is unblocked when the adapter device is separated from the first air outlet. As a result, for example, an automatic transition into an operating mode in which the decoupling of the process air via the first air outlet and the second air outlet takes place when an operator separates the adapter device from the first air outlet, which enables a comfortable operation of the suction apparatus.
- It may be advantageous if the at least one wall element of the adapter device has a curved shape and/or if the at least one wall element lies in a geometrical cylinder portion. The at least one wall element can thereby be connected, for example, to a cylindrical hose element in a technically simple manner, thereby making it possible for the adapter device to be arranged or formed on a cylindrical hose element in a technically simple manner.
- It may be favorable if the suction apparatus comprises a connecting device, by which the adapter device is releasably fixable and/or releasably latchable to the first air outlet.
- In particular, provision may be made that the suction apparatus comprises a connecting device, by which the adapter device is releasably fixable and/or releasably latchable to the suction port.

- For example, within the suction head, the second channel is in fluidic connection with a connecting channel for supplying process air from the suction blower device to the first channel and/or the second channel when the adapter device is separated from the first air outlet.
- For example, within the suction head, the second channel is closed in a fluid-tight manner relative to a connecting channel for supplying process air from the suction blower device to the first channel and/or the second channel in the suction head when the adapter device is properly connected to the first air outlet.
- For example, within the suction head, the first channel is in fluidic connection with a connecting channel for supplying process air from the suction blower device to the first channel and/or the second channel when the adapter device is separated from the first air outlet.
- For example, within the suction head, the first channel is in fluidic connection with a connecting channel for supplying process air from the suction blower device to the first channel and/or the second channel when the adapter device is properly connected to the first air outlet.
- In accordance with an embodiment of the invention, provision is made in the suction apparatus stated at the outset that a smallest angle between a first longitudinal central axis of the first channel and a second longitudinal central axis of the second channel is at least 40° and/or at most 70°.
- A torque exerted on the suction apparatus and/or on the suction head upon the decoupling of process air from the suction head during operation can thereby be reduced. Undesired movements and, in particular, undesired rotational movements of the suction apparatus during operation can thereby be reduced. An operation of the suction device that is as comfortable as possible is thereby made possible.
- The suction apparatus can thereby also be comfortably used, in particular, when it has, for example, reduced static friction relative to a ground, for example because the ground is smooth or because the suction apparatus is equipped with rollers for moving on the ground. In the case of the suction apparatus in accordance with the invention, undesired (rotational) movements resulting from the decoupling of process air can be reduced in these situations, too.
- In particular, provision may be made that a smallest angle between the first longitudinal central axis of the first channel and the second longitudinal central axis of the second channel is at least 50° and/or at most 60°. A torque on the suction apparatus that arises upon the decoupling of process air can thereby be further reduced.
- It may be favorable if a smallest angle between a main flow direction of process air conducted through the first channel and a main flow direction of process air conducted through the second channel is at least 40° and/or at most 70° and, in particular, at least 50° and/or at most 60°.
- For example, a first longitudinal central axis of the first channel and a second longitudinal central axis of the second channel lie at least approximately in a common plane, wherein the plane is oriented transversely and, in particular, perpendicularly to a longitudinal central axis and/or to a height direction of the suction apparatus.
- For example, a main flow direction of process air conducted through the first channel and a main flow direction of process air conducted through the second channel lie at least approximately in a common plane, wherein the plane is oriented transversely and, in particular, perpendicularly to a longitudinal central axis and/or to a height direction of the suction apparatus.
- For example, an outer contour of the first air outlet is of at least approximately circular configuration.

A torque arising during the coupling of process air can thereby be further reduced.
- For example, a first midpoint of an outer contour of the first air outlet and a second midpoint of an outer contour of the second air outlet are at least approximately at the same height with respect to a height direction of the suction apparatus.
- For example, a lower end of the at least one first air outlet and a lower end of the second air outlet are at least approximately at the same height with respect to a height direction of the suction apparatus.
- For example, an upper end of the first air outlet and an upper end of the second air outlet are at least approximately at the same height with respect to a height direction of the suction apparatus.
- For example, the second air outlet has an at least 10% and, in particular, at least 15% and, in particular, at least 20% greater cross sectional area than the first air outlet. As a result, a decoupling of process air via an enlarged cross sectional area can be achieved, thereby reducing a flow speed and/or a pressure of the decoupled air.
- For example, an outer contour of the second air outlet is of substantially rectangular configuration.
- For example, an outer contour of the second air outlet lies in a geometrical rectangle at least one sections.
- For example, at least three of four edge portions of the outer contour of the second air outlet lie in a geometrical rectangle.
- For example, a fourth edge portion of the outer contour of the second air outlet comprises a first subportion and a second subportion adjoining the first subportion, wherein the second subportion is oriented transversely to the first subportion.
- For example, at least one edge portion of the outer contour of the second air outlet is oriented transversely and, in particular, perpendicularly to a height direction of the suction apparatus.
- For example, an edge portion of the outer contour of the second air outlet pointing toward the first air outlet is of rectilinear configuration.
- It may be favorable if the first channel and the second channel have flow spaces for air that are fluidically separated or fluidically separable from one another. The second channel can thereby be fluidically separated from the first channel within the suction head so that, for example, no decoupling of process air is able to take place via the second channel.
- It may be advantageous if a flow cross section of the first channel is at least approximately constant. As a result, for example, the connection of the adapter device to the first air outlet can be realized in a technically simple manner.
- It may be favorable if a flow cross section of the second channel expands toward the second air outlet, and in particular if the flow cross section of the second channel is greatest at an end of the second air outlet that points toward the second air outlet and/or is smallest at an end of the second channel that points away from the second air outlet. A flow speed of process air decoupled through the second channel can thereby be reduced.
- In particular, provision may be made that the channel device comprises a connecting channel for producing a fluidic connection between an exit of the suction blower device and the first air outlet and/or the second air outlet, wherein air to be decoupled from the suction head by the connecting channel is divided or is divisible to the first channel and/or to the second channel. For example, process air can thereby be suppled to the first channel and the second channel simultaneously to be decoupled.
- For example, the connecting channel is arranged in an inside space of the suction head.
- For example, the connecting channel comprises a first subregion in which a flow cross section of the connecting channel is at least approximately constant.
- For example, the connecting channel comprises a second subregion adjoining a first subregion, wherein the second subregion points toward the first channel and/or the second channel, and wherein a flow cross section of the connecting channel in the second subregion expands and, in particular, monotonously expands toward the first channel and/or toward the second channel. As a result, for example, a division of process air to the first channel and the second channel can be achieved in a technically simple manner.
- For example, the connecting channel surrounds the suction blower device in sections.
- For example, the connecting channel has a shape that is curved toward a longitudinal central axis of the suction apparatus, wherein the longitudinal central axis is oriented in parallel to a height direction of the suction apparatus.
- For example, the connecting channel is arranged between an exit and/or exit channel of the suction blower device and the first channel and/or the second channel with respect to a main flow direction of air decoupled from the suction blower device.
- For example, a transition region for air is formed between an exit and/or exit channel of the suction blower device and the connecting channel.
- For example, a transition region for air formed between an exit and/or exit channel of the suction blower device and the connecting channel is configured in such a way that a main flow direction of air decoupled from the suction blower device reverses and, in particular, reverses by at least approximately 180° in the transition region. As a result, torques on the suction head that arise upon the decoupling of process air are further reduced.
- In one embodiment, the suction apparatus comprises at least one air guiding element for distributing air to be decoupled from the suction head to the first channel and the second channel, wherein the at least one air guiding element is arranged in the connecting channel or is associated with the connecting channel.

- For example, the at least one air guiding element is arranged in a subregion and/or end region of the connecting channel that points toward the first channel and/or second channel.
- For example, an air guiding element and a further air guiding element spaced at a distance from the air guiding element are provided, wherein the air guiding element and the further air guiding element, in particular, are oriented at least approximately in parallel to one another.

In the example shown, theabutment region 230 comprises afirst subregion 230 a for the abutment of thefirst leg element 206 of thegripping bar 202 and asecond subregion 230 b for the abutment of thesecond leg element 208. For example, thefirst subregion 230 a and thesecond subregion 230 b are arranged opposite one another on the suction head housing. For example, thefirst subregion 230 a and thesecond subregion 230 b are arranged on different and/or opposite sides of thecover element 76 of thesuction head housing 68. - The
abutment region 230 lies, for example, in a plane oriented transversely and, in particular, perpendicularly to the longitudinalcentral axis 28. Theabutment region 230 extends in theoutside region 214 and/or rim region of thesuction head housing 68 between the pivot joints 212 and the receivingregion 216. - For example, the
abutment region 230 and/or thefirst subregion 230 a and/or thesecond subregion 230 b transition into atransverse portion 232 formed on the outside 218, which delimits the receivingregion 216. Thistransverse portion 232 is oriented transversely to theabutment region 230 and/or to thebottom portion 228. Thetransverse portion 232 is arranged between thebottom portion 228 and theabutment region 230. - For example, a smallest angle between the
transverse portion 232 and thebottom portion 228 is about 65°. - The holding
device 92 and the associated receivingregion 216 are configured at least approximately mirror symmetrical to a plane, for example mirror symmetrical to themidplane 192 extending through the longitudinalcentral axis 28. - The holding
device 92 and the associated receivingregion 216 are arranged in theoutside region 214 and/or rim region of thesuction head housing 68 with respect to thetransverse direction 174, wherein the holdingdevice 92 is arranged on anouter contour 234 of thesuction head housing 68. - The

For example, theouter contour 234 comprises at least approximately a constant curvature and/or a constant radius of curvature. - For example, the
outer contour 234 extends throughouter sides 235 of thesuction head housing 68 located in theoutside region 214 and/orrim region 214, which adjoin the receivingregion 216 in the peripheral direction. - The receiving
region 216 is configured as an indentation with respect to theouter contour 234. - The receiving
region 216 extends inwardly commencing from theouter contour 234 and/or from the holding device 92 (toward thecover element 76 and/or toward the longitudinal central axis 28). - The holding
device 92 extends in theheight direction 32 from alower end 236 to anupper end 238 of the receivingregion 216. For example, thebottom portion 228 is located at the height of thelower end 236 and thetransverse portion 232 extends between thelower end 236 and theupper end 238. - For example, the holding
device 92 is configured as ahook element 239 or comprises ahook element 239. - The holding
device 92 comprises asecond region 240, which is arranged in anupper end region 242 of the holdingdevice 92. Thesecond region 240 is connected to afirst region 244 of the holdingdevice 92, wherein thefirst region 244 is connected to thesuction head housing 68. - For example, the
second region 240 is connected to thefirst region 244 by means of a screw connection. Thefirst region 244 is, for example, connected to thesuction head housing 68 in one piece. - The
second region 240 projects beyond the first region in thetransverse direction 174. For example, thesecond region 240 projects beyond thefirst region 244 in thetransverse direction 174 toward thecover element 76 and/or toward the longitudinalcentral axis 28. - The holding
device 92 has width B1, wherein a width direction is oriented in theperipheral direction 100 of thesuction head housing 68. The width B1 is greatest at alower end 246 of the holdingdevice 92 and is smallest at anupper end 248 of the holdingdevice 92. - The
lower end 246 is located at the height of thelower end 236 of the receivingregion 216 and theupper end 248 is located at the height of theupper end 238 of the receivingregion 216. - The holding
device 92 comprises anupper end face 250, which is oriented at least approximately in parallel to theabutment region 230. For example, the upper end face is located at least approximately at the height of theabutment region 230 with respect to theheight direction 32. For example, theabutment region 230 and theupper end face 250 are lie at least approximately in a plane. - For example, the
grip element 210 of thegripping bar 202 abuts against theupper end face 250 when thegripping bar 202 is located in thefirst position 203 a. For example, the upper end face 250 forms an abutment region for thegripping bar 202 and/or thegrip element 210. - The holding
device 92 comprises an outside 252, which faces away from the receivingregion 216 and/or the longitudinalcentral axis 28. The outside 252 is lies, for example, in theouter contour 234. - Provision may be made that a
locking device 254 is associated with thegripping bar 202, by which thegripping bar 202 can be fixed and/or snapped in and/or latched in thefirst position 203 a. For example, the grippingbar 202 can be fixed and/or snapped in and/or latched in thefirst position 203 a on the holdingdevice 92 by thelocking device 254. - In one embodiment, associated with the
gripping bar 202 is aspring device 256, by which thegripping bar 202 can be transferred from thefirst position 203 a into thesecond position 203 b in the direction of or counter to a spring force exerted by thespring device 256. For example, thespring device 256 is arranged or formed on at least one of the pivot joints 212. - The first pivot joint 212 a comprises a
pin element 258, which is arranged and/or formed on thefirst leg element 206. When thegripping bar 202 is properly positioned on thesuction apparatus 10, thispin element 258 extends from thefirst leg element 206 in the direction of thecover element 76 of thesuction head 20. For example, thepin element 258 projects commencing from thefirst leg element 206 in the direction of thecover element 76. - For example, the first pivot joint 212 a and/or the
pin element 258 are arranged on anend 259 and/or end region of thegripping bar 202 located on thecover element 76. - Furthermore, the first pivot joint 212 a comprises a
sleeve element 260 for rotatably mounting thepin element 258. For example, thepin element 258 can be accommodated by thesleeve element 260 and/or thepin element 258 is insertable into thesleeve element 260. - For example, the
pin element 258 is arrangeable on thesleeve element 260 and/or is insertable into thesleeve element 260 toward thecover element 76. - The
sleeve element 260 is arranged and/or formed on thecover element 76. For example, thesleeve element 260 is configured as an indentation on awall element 262 of thecover element 76 facing toward thefirst leg element 206 and/or thepin element 258. - Adjoining the
wall element 262, for example, in theperipheral direction 100 is thewall element 221 of thecover element 76, which faces toward thegrip element 220 when thegripping bar 202 is located in thefirst position 203 a. - In the embodiment depicted, the pivot joint 212 a is of identical configuration as the second pivot joint 212 b.
- By way of the first pivot joint 212 a and/or the second pivot joint 212 b, the gripping
bar 202 is pivotable about apivot axis 264 and/or rotational axis, which is oriented, for example, transversely and, in particular, perpendicularly to the longitudinalcentral axis 28 and/or to theheight direction 32. - In one embodiment, a delimiting
element 266 associated with the first pivot joint 212 a, by which a movement of thefirst leg element 206 in a direction away from thecover element 76 is blocked when thegripping bar 202 is located in thesecond position 203 b. Correspondingly, provision may be made that a delimitingelement 266 is associated with the second pivot joint 212 b. - In the embodiment shown, the delimiting
element 266 is arranged on thesuction head 20 at a distance from thecover element 76 and/or at a distance from thesleeve element 260. The delimitingelement 266 is arranged in aregion 268 located at the pivot joint 212 a. - For example, the delimiting
element 266 is arranged at thefirst subregion 230 a of theabutment region 230. For example, the delimitingelement 266 is configured as a raised portion. - The
gripping bar 202 comprises aninner wall element 268 that faces toward thecover element 76 and anouter wall element 270 that faces away from thecover element 76. Thepin element 258 is arranged, in particular, on theinner wall element 268. - Formed between the
inner wall element 268 and theouter wall element 270 is, in particular, aninterspace 272 which, in particular, is open toward abottom side 274 of thegripping bar 202, wherein thebottom side 274 faces toward theabutment region 230 when the gripping bar is located in thefirst position 203 a. - Arranged in the
interspace 272 are, for example, one ormore rib elements 276, which are arranged between theinner wall element 268 and theouter wall element 270. For example, therib elements 276 are oriented transversely and, in particular, perpendicularly to theinner wall element 268 and/or theouter wall element 270. - The delimiting
element 266 is arranged, at least in sections, in theintermediate space 272 and/or is arranged, at least in sections, between theinner wall element 268 and theouter wall element 270. - When the
gripping bar 202 is located in thesecond position 203 b, the delimitingelement 266 is arranged between theouter wall element 270 and astop element 278. Thisstop element 278 can abut against the delimitingelement 266 and thereby prevents a movement of thefirst leg element 206 in a direction away from thecover element 76 when thegripping bar 202 is located in the second position. - As a result of the cooperation of the delimiting
element 266 and thestop element 278, a movement of thefirst leg element 206 in a direction away from thecover element 76 is prevented when thegripping bar 202 is located in thesecond position 203 b. It is thereby prevented that thepin element 258 in thesecond position 203 b moves out of thesleeve element 260. - The
stop element 278 can be pivoted and/or rotated about the pivot axis 267 relative to the delimiting element, such that a movement of thegripping bar 202 from thesecond position 203 b into thefirst position 203 a is possible. - For example, the
stop element 278 is arranged in theinterspace 272 between theouter wall element 270 and theinner wall element 268. For example, thestop element 278 is arranged on arib element 276 a, which is oriented transversely and, in particular, perpendicularly to theinner wall element 268 and/or theouter wall element 270. Thestop element 278 is oriented, for example, transversely and, in particular, perpendicularly to therib element 276 a. - Provision may be made that a
recess 280 is formed on therib element 276 a, wherein the delimitingelement 266 can be passed or is passed, at least in sections, through therecess 280 when thegripping bar 202 is moved from thesecond position 203 b into thefirst position 203 a. - In the
first position 203 a, the delimitingelement 266 is arranged at a distance from thestop element 278. Thestop element 278 can then be moved relative to the delimitingelement 266, in particular without being hindered by the delimitingelement 266. For example, the grippingbar 202 in thefirst position 203 a is movable between a first position in which the delimitingelement 266 abuts against theouter wall element 270 and a second position in which the delimitingelement 266 abuts against the inner wall element 268 (cf.FIGS. 14 and 15 ). - In the first position, the
pin element 258 is arranged in thesleeve element 260. In the second position, thepin element 258 is arranged outside thesleeve element 260. Thegripping bar 202 in thefirst position 203 a can thereby be mounted to or dismounted from thesuction head 20 in atoolless manner 20. - The suction apparatus in accordance with the invention functions as follows:
- For performing a suction operation using the
suction apparatus 10, an operator connects, for example, the suction hose of thesuction apparatus 10 to thesuction port 34. The user then switches on thesuction apparatus 10, for example by way of theoperating element device 82. Corresponding parameters of the suction apparatus can, for example, be controlled by the operator by way of theoperating element device 82. - (Dirty) process air is coupled through the
suction port 34 into the receivingspace 14 of the suctionedmaterial container 12 by thesuction blower device 22. - The dirt content of the coupled process air is discharged into the receiving
space 14 of the suctionedmaterial container 12 and/or on the dirty side 64 of thefilter unit 56. - (Clean) process air is coupled into the
suction blower device 22 via theclean side 60 of thefilter unit 56. This process air is then decoupled from thesuction head 20 via thefirst air outlet 102 and thesecond air outlet 104 by thechannel device 96. - For emptying the suctioned
material container 12, the fixingdevice 52 is opened and then thesuction head 20 is lifted upwardly from the suctionedmaterial container 12 using thegripping bar 202. For this purpose, the grippingbar 202 is transferred by a user into thesecond position 203 b. After emptying the suctionedmaterial container 12, thesuction head 20 is placed back onto the suctionedmaterial container 12 using thegripping bar 202 and then is fixed to said suctionedmaterial container 12 with the fixingdevice 52. - For performing a blowing operation using the
suction apparatus 10, the suction hose is connected to the connectingdevice 184 of thefirst air outlet 102 by theadapter device 186. - As a result, the
closure device 185 is transferred from the first state into the second state, such that no process air is decoupled from thesuction head 20 through thesecond air outlet 104. The decoupling of the process air then takes place via thefirst air outlet 102 and, in particular, exclusively via thefirst air outlet 102. - The process air is thereby coupled into the suction hose and decoupled at an end of the suction hose, so that the blowing function is usable by the user using the suction hose.
- For storing the
suction apparatus 10, the suction hose is, for example, released from thesuction port 34 and/or from the connectingdevice 184. For example, the suction hose may be fixed to and/or stored on thesuction head 20 using the holdingelement 79. - The
cable 94 of thesuction apparatus 10 can be held and/or stored on thesuction head 20 using the holdingdevice 92 and the receivingregion 216 associated with the holdingdevice 92. - For arranging the
cable 94 in the receivingregion 216, the operator transfers thegripping bar 202 into thesecond position 203 b so that the receivingregion 216 on thesuction head 20 is accessible from above (see e.g.FIG. 1 ). In this state, thecable 94 can be arranged in the receivingregion 216 and be, for example, rolled up and/or arranged as a loop there. - Then, the gripping
bar 202 is transferred by the operator, for example, into thefirst position 203 a, so that thegripping bar 202 adjoins the receivingregion 216. In this position of thegripping bar 202, a movement of thecable 94 arranged in the receivingregion 214 in a direction upward and in atransverse direction 174 outwards is blocked (see e.g.FIG. 2 ). - For removing the
cable 94 from the receivingregion 216, the operator transfers the gripping bar from thefirst position 203 a into thesecond position 203 b, so that a removal of thecable 94 upwards out of the receivingregion 216 is made possible (see e.g.FIG. 1 ). - For dismounting the
gripping bar 202 without tools, it is transferred into thefirst position 203 a. Thefirst leg element 206 is pushed outwardly away from thecover element 76 by an operator until the delimitingelement 266 abuts against theinner wall element 268 and/or until thepin element 258 has receded from the sleeve element 260 (cf.FIG. 15 ). Thefirst leg element 206 can then be moved upwards away from the suction head when thepin element 258 is decoupled. This is then repeated accordingly with thesecond leg element 208 when thefirst leg element 206 is dismounted, so that thegripping bar 202 is released from thesuction head 20. For toolless assembly, the stated steps are performed accordingly in reverse order. -
