Description

Mobile workstation comprising a mobile vacuum cleaner and a storage unit

Technical Field

In general, the present invention is in the field of vacuum suction devices, preferably used in conjunction with hand-held power tools that generate dust or powder particles during their intended use, such as in conjunction with hand-held sanders, polishers, or grinders. In particular, the present invention relates to a mobile workstation comprising a mobile vacuum cleaning device and a storage unit attached to the mobile vacuum cleaning device and adapted to store a hand-held power tool, an accessory for the power tool, consumables for the power tool and/or other items. Vacuum cleaners are similar to conventional cleaners used by homes or hobby tradesmen, but are generally more powerful and efficient in terms of air throughput, dust capacity and filtration efficiency.

The main idea of such a mobile workstation is to combine the industrial vacuum cleaner with a storage unit in order to enable easy and flexible manoeuvring of the workstation to the desired working position and at the same time provide sufficient functional storage options in the mobile workstation in order to bring all necessary hand-held power tools, accessories for power tools, consumables for power tools and/or other hand-held items within reach of the user when in the working position. This makes it possible to optimize the working process, for example during repair, refurbishment and/or polishing of the surface of the vehicle body or ship hull.

Background

Basically, there are two different types of mobile stations in the prior art. The first type is based on a mobile cart comprising a storage unit adapted to store a storage unit for a hand-held power tool, accessories for a power tool, consumables for a power tool and/or other items. Furthermore, the trolley comprises a storage compartment for the vacuum cleaning device. Such mobile workstations are supplied and sold by Norton (Norton) corporation, residing in the united states, under the name "Vac Rack". The second type is based on a mobile vacuum cleaner and a storage unit attached to the mobile vacuum cleaner and adapted to store a hand-held power tool, accessories for the power tool, consumables for the power tool and/or other items. For example, finnish corporation KWH mill card (Mirka) supplies and sells a second type of workstation for its vacuum cleaner 1230. Furthermore, German company Stokes (Festool) supplies and sells such a workstation named "Stokes 497471CT working centre WCR-1000 (Festool 497471CT workshop WCR-1000)".

Known mobile workstations have the disadvantage that they have only a relatively limited flexibility in terms of the type and number of power tools, accessories, consumables and other items that can be stored in the storage unit of the mobile workstation. In particular, the storage units of known mobile workstations have a predominantly static structure, which results in storage units having a sufficiently large storage capacity when in use, but which require a large space even when not in use, or which require little space when not in use, but which have a rather limited storage capacity when in use.

SUMMERY OF THE UTILITY MODEL

It is therefore an object of the present invention to provide a mobile workstation with a greater degree of flexibility, which in particular comprises a storage unit which, on the one hand, has a large storage capacity when in use and, on the other hand, requires only a very limited amount of space when not in use.

This object is solved by a mobile workstation: a mobile workstation comprising a mobile vacuum cleaning apparatus and a storage unit attached to the mobile vacuum cleaning apparatus, wherein a top portion of a housing of the mobile vacuum cleaning apparatus comprises at least one movable part adapted to move between a closed position and an open position, wherein the at least one movable part forms a receiving chamber when in the open position, the at least one movable part being in the form of a cover element adapted to hinge between the closed position and the open position about a first hinge axis, the first hinge axis extending in a substantially horizontal plane. In particular, starting from a mobile workstation of the above-mentioned type, it is proposed that the top of the housing of the mobile vacuum cleaning apparatus comprises at least one movable part which is adapted to be moved between a closed position and an open position, wherein the at least one movable part forms a receiving chamber which, in the open position, is adapted to receive a hand-held power tool, an accessory for the power tool, a consumable for the power tool and/or other items.

In the mobile workstation according to the invention, the mobility of the workstation is preferably achieved by means of a mobile vacuum cleaner provided with wheels. Vacuum cleaning devices are similar to conventional vacuum cleaners used by homes or amateur trades, except that they are generally more powerful and efficient in terms of air throughput, dust capacity and filtration efficiency. The vacuum cleaning device comprises a housing, preferably made of plastic and/or metal, which can be composed of two separate parts. The first bottom part of the housing can have the form of a chamber and be adapted to receive a primary filter element, for example in the form of a vacuum cleaner bag. The bottom part of the housing is equipped with wheels in order to enable the vacuum cleaning apparatus to move freely over the floor of the space where it is used. Furthermore, the bottom part of the housing comprises at least one air inlet opening for attaching a first end of a vacuum hose for attachment of the first end of the vacuum hose for suction of dust laden air, for example air from a hand held power tool, for example a sander, a grinder or a polisher. The opposite end of the vacuum hose is attachable to the power tool.

The second top part of the housing can comprise an electric or pneumatic drive (e.g. an electric or pneumatic motor and turbine) for generating a vacuum for drawing dust laden air. The top part of the housing can be releasably attached to the bottom part of the housing, for example by means of a quick-release clamping element. Furthermore, the top part of the housing can comprise electric and/or pneumatic input and output means for controlling the operation of the vacuum cleaning device, such as buttons, rotary switches and/or power sockets, pneumatic sockets.

Furthermore, the mobile workstation comprises a storage unit attached to the mobile vacuum cleaning apparatus and adapted to store the hand-held power tool, the accessories for the power tool, the consumables for the power tool and/or other items. The storage unit can comprise a storage rack, a container, a compartment, a paper holder and/or a support arm for supporting a vacuum hose of the mobile vacuum cleaning apparatus. According to the present invention, it is proposed that the top part of the housing of the mobile vacuum cleaning device comprises at least one movable part adapted to be moved between a closed position and an open position. The at least one movable member forms a receiving chamber adapted to receive a hand-held power tool, an accessory for a power tool, a consumable for a power tool, and/or other items when the movable member is moved into its open position. This has the advantage that the at least one movable part can be moved into its closed position when the mobile workstation is not in use, thereby taking up as little space as possible. On the other hand, when the at least one movable part is in its open position, it provides an additional receiving compartment with a large amount of storage space. Furthermore, the at least one movable part of the top part provides additional walls and cavities in the area of the top part when the at least one movable part is in its closed position, resulting in a significant reduction of the noise emitted by the electric or pneumatic drive means used for generating the vacuum during the intended use of the vacuum cleaning apparatus.

Preferably, the top of the housing of the mobile vacuum cleaning apparatus comprises a first receiving portion adapted to receive and secure at least one receptacle when the at least one movable part is in its closed position, the receptacle being embodied as a separate entity from the mobile vacuum cleaning apparatus. According to this embodiment, the at least one container can be received and fixed at a first receiving portion provided on top of the top part of the housing, even when the at least one movable part is in its closed position. At least one container is preferably of a standard type, such as that from Tanos GmbH, Germany

To this end, the first receiving portion on the top of the housing has a substantially flat extension corresponding to the bottom surface of the containerAnd (5) kneading. Furthermore, depending on the type of container to be received and secured, the first receiving portion can be provided with recesses and/or projections for positioning and holding the container in a predetermined position. Finally, still depending on the type of container to be received and secured, the first receiving portion can be provided with securing means for releasably securing the container to the top part of the housing.

According to another embodiment of the invention, the top of the housing of the mobile vacuum cleaning apparatus comprises a second receiving portion adapted to receive and secure at least one container when the at least one movable part is in its open position, the container being implemented as a separate entity from the mobile vacuum cleaning apparatus. According to this embodiment, the at least one container can be received and secured at the second receiving portion when the at least one movable member is in its open position and provides a storage compartment. The container can be box-shaped, closed by a lid, or bowl-shaped, open and accessible from the top. The second receiving portion can be the same as the first receiving portion. However, it is preferred that the first receiving portion and the second receiving portion are different from each other. Thus, only the first receiving portion is accessible when the at least one movable part of the top of the housing is in its closed position. Only the second receiving portion is accessible when the at least one movable part of the top of the housing is in its open position.

Preferably, at least one container is a box of standard type, such as those from Tanos GmbH, Germany

For this purpose, the second receiving portion has a substantially flat extension, which corresponds to the bottom surface of the container. Furthermore, depending on the type of container to be received and secured, the second receiving portion can be provided with recesses and/or projections for positioning and holding the container in a predetermined position. Finally, still depending on the type of container to be received and secured, the second receiving portion can be provided with securing means for releasably attaching the container to the top part of the housing in a predetermined position.

According to yet another preferred embodiment of the invention, it is proposed that the top part of the housing of the mobile vacuum cleaner comprises a third receiving portion adapted to receive and fix the at least one partition wall when the at least one movable part is in its open position. According to this embodiment, wherein the at least one movable member is in its open position, the storage unit not only provides one or more storage compartments, but also a partition wall for storing the hand-held power tool, accessories for the power tool, consumables for the power tool and/or other items. For this purpose, the partition wall can be provided with a shelf, a hook and a holder. The partition wall can be embodied as a perforated plate with a plurality of holes, which are preferably distributed uniformly relative to each other along the entire plate. The rack, hooks, and retainers can then be individually positioned and releasably attached to the perforated plate using one or more holes. The partition wall is made of plastic or metal. When not in use, the partition wall is preferably stored in another location, in particular a location which does not form part of the mobile work station, for example in a separate storage compartment provided between two vertical rods of the handle of the mobile work station. The third receiving portion can be an integral part of the second receiving portion, enabling the container or the partition wall to be selectively received and attached through the top of the housing when the at least one movable member is in its open position.

Preferably, the third receiving part of the housing of the mobile vacuum cleaner comprises two guide rails, each guide rail being adapted to hinge between a folded position and an unfolded position about a second hinge axis extending in a substantially horizontal plane, such that the guide rails in the unfolded position face each other, and the partition wall is insertable into and retained by the guide rails. It is proposed that the top part of the housing comprises a recess for receiving the guide rail in its folded position, thereby forming a flat surface of the second receiving portion. Thus, when the rail is in its folded position, the at least one container can be received and releasably attached to the second receiving portion. When there is no container received and attached to the second receiving portion, the rail can be hinged into its deployed position and the partition wall can be inserted into and retained by the rail. The guide rail has a substantially vertical extension in its deployed position, so that the partition wall inserted therein also has a vertical extension.

The at least one movable part of the top part of the housing can have many different embodiments in order to provide at least one storage compartment when the at least one movable part is in its open position. For example, it is proposed that the at least one movable part is in the form of a drawer adapted to be moved in a substantially horizontal plane between a closed position and an open position by means of at least one linear guide element. Preferably, the at least one linear guide element has a horizontal extension. Preferably, each drawer is assigned two linear guide elements. The linear guide elements are disposed on outer surfaces of two opposite lateral sides of the drawer.

Optionally, it is suggested that the at least one movable part is in the form of a cover element adapted to hinge between the closed position and the open position about a first hinge axis extending in a substantially horizontal plane. Preferably, the first hinge axis of the at least one cover element extends in a horizontal plane parallel to the longitudinal extension of the mobile work station, such that the at least one cover element can be hinged to a lateral side of the housing. It is further preferred that the mobile workstation comprises two cover elements which can be hinged to both lateral sides of the housing, which when the cover elements are in their closed position and when they are in their open position provide a symmetrical design with respect to the longitudinal extension of the mobile workstation. The cover element, when in its open position, can be embodied as a bowl which is open and freely accessible from the top. Optionally, the cover element, at least when in its open position, can also be closed by an additional cover. The inner side of the cover element is only accessible from the top when the additional cover is opened. An additional lid can be hinged to the remainder of the cover element. When closed, the additional lid is held to the rest of the lid element by means of snaps, magnets or other closing means. In this way, the additional cover will remain closed even if the cover element is brought into its closed position, and the items contained in the cover element will not fall out. The cover element can be held in its closed position by means of magnetic force. For this purpose, the top part and the cover element of the vacuum cleaner are provided with corresponding magnetic and/or ferromagnetic elements.

Preferably, the or each cover element has an exterior side surface adapted to lie against a lateral side surface of the housing of the mobile vacuum cleaning device when the or each cover element is in its open position, wherein the first hinge axis is located between the exterior side surface of the cover element and the lateral side surface of the remainder of the top part of the housing. The remaining part of the outer side surface of the cover element is placed against the lateral side surface of the housing when the cover element is in its open position, which provides a very stable and strong storage compartment when the cover element is in its open position.

According to yet another alternative embodiment, the at least one movable part is in the form of a cover element of the housing, the cover element being adapted to be moved between the closed position and the open position by means of a guide mechanism acting between the at least one cover element and the remainder of the top part of the housing of the mobile vacuum cleaning apparatus. Preferably, the guide mechanism comprises at least two guide rods on opposite sides of the at least one cover element and providing translational movement of the at least one cover element between the closed position and the open position. It is suggested that the outer side surface of the at least one cover element is placed against the lateral side surface of the housing of the mobile vacuum cleaning apparatus when the at least one cover element is in its open position.

It is further proposed that the mobile work station comprises a handle adjustable between an insertion position and at least one extracted position, the handle comprising a handlebar adapted to be gripped by a user for freely moving the mobile work station on the floor of the space, wherein the handlebar is height-adjustable by extracting and inserting the handle and the handlebar is fixable in the at least one extracted position. Preferably, the handle has two telescopic rods having a substantially vertical extension, the stationary telescopic element of each vertical rod being attached to the mobile dust extraction, in particular to the bottom part of the housing. An opposite extractable telescoping member is attached to the handlebar. The fixing of the handlebar in the desired extracted position is preferably achieved by means of a quick-lock or quick-clamp mechanism. The height-adjustable handle has the advantage that it can be inserted completely, so that only very little space is required, if no mobile workstation is used and/or no handle is required.

Preferably, the at least one storage rack is attached to the handle in a manner foldable about a substantially horizontal folding axis, wherein the storage rack is adapted to be folded about the horizontal folding axis between a rest position and a working position, and wherein the storage rack is adapted to be held or fixed in its working position. The at least one storage rack is preferably attached to both vertical rods of the handle, in particular to the extractable element of the vertically telescopic rod of the handle, so that the height of the at least one storage rack can be adjusted together with the height adjustment of the handlebar. When the storage rack is not needed, it can be brought into the rest position, so that only a very small space is needed. When one or more storage shelves are needed, they can be folded into a working position, thereby providing additional storage space for hand-held power tools, accessories for power tools, consumables for power tools, and/or other items. When the storage rack is in its working position, one or more support bars may be brought into a supporting position below the storage rack, supporting and holding the storage rack in the working position. In particular, the support bar can be hinged about a third hinge axis into a position below the storage rack. The third hinge axis of the support bar extends substantially perpendicular to the horizontal folding axis of the storage rack and thus extends in the vertical direction. The upper support surface of the support bar in its support position extends substantially in the same plane as the bottom surface of the storage rack in its operative position.

Furthermore, it is proposed that the mobile workstation comprises at least one support arm which is rotatable about a substantially vertical first axis of rotation, the support arm having an upper portion and being adapted to support a vacuum hose of the mobile vacuum cleaning apparatus, the upper portion having a substantially horizontal extension. The at least one support arm is preferably attached to the handle and can be height-adjusted together with the handle. Alternatively, the support arm can also be attached to a stationary part of the housing, preferably to a bottom part of the housing, or to a stationary telescopic element of a vertically telescopic rod of a handlebar, with which the handlebar is attached to the housing, preferably to the bottom part of the housing. Preferably, the support arm comprises a clamping element for releasable attachment of a vacuum hose of the mobile vacuum cleaning apparatus.

According to another preferred embodiment it is proposed that the mobile workstation comprises at least two support legs, each support leg being adapted to be moved between a folded position, in which the support leg is placed against a side of the housing of the mobile vacuum cleaner, and an unfolded position, in which the support leg extends away from the side of the housing of the mobile vacuum cleaner, preferably in a radial direction. An intermediate position can be defined between the folded position and the unfolded position. The support legs can be releasably secured in their respective positions, for example by means of a detent mechanism, a quick lock mechanism or a quick clamp mechanism. The distal ends of the support legs each include a support element that is height adjustable so as to be able to be brought into contact with the floor on which the mobile workstation stands when the support legs are in their deployed position. The support legs provide a high stability of the mobile workstation during its intended use. In its folded position with the retracted support element, the support leg requires only a very small space. In its deployed position with the extended support elements, the support legs increase the standing surface of the mobile workstation. The support legs are preferably attached to the bottom part of the housing, in particular to vertical bars of a handle attached to the bottom part of the housing.

It is proposed that the support legs are rotatable about a vertical second axis of rotation to move the support legs between the folded and unfolded positions, and wherein the support element is attached to the distal ends of the support legs by means of a vertical threaded connection. In this embodiment, the support element can be retracted and extended in the vertical direction by rotating the support element in a threaded connection.

Alternatively, it is suggested that the support legs are rotatable about a second axis of rotation having a slightly inclined extension with respect to the vertical extension, so as to move the support legs between the folded and unfolded positions. Due to the inclination of the second rotation axis, the support element is lowered when the support legs are brought into the unfolded position and raised when the support legs are brought into the folded position. In this embodiment, the support element is automatically retracted and extended in the vertical direction by moving the support leg between the folded and unfolded positions.

Furthermore, according to another preferred embodiment, it is suggested that at least one wing wall is attached to the mobile workstation in a foldable manner about a substantially vertical folding axis, wherein the at least one wing wall is adapted to be folded about the vertical folding axis between the rest position and the working position. An intermediate position can be defined between the rest position and the working position. The wing walls can be releasably secured in their respective positions, for example by means of a detent mechanism, a quick-lock mechanism or a quick-clamp mechanism. The at least one wing wall is preferably attached to a vertical rod of the handle, in particular to an extractable element of a vertically telescopic rod of the handle, so that the height of the at least one wing wall can be adjusted together with the height adjustment of the handlebar. The at least one wing wall is attached to the handle such that the wing wall is foldable about a substantially vertical folding axis between a rest position and a working position. The at least one wing wall is preferably embodied as a perforated plate with a plurality of holes, which are preferably distributed uniformly relative to each other along the entire plate surface. The rack, hooks, and retainers can be individually positioned and releasably attached to the perforated plate using one or more holes. The at least one wing wall is made of plastic or metal. Preferably, the mobile workstation has two wing walls, each wing wall being attached to a vertical post of the handle. A symmetrical design of the mobile workstation with respect to its longitudinal extension can be maintained when both wing walls are in their deployed position. Preferably, the deployed position of the wing walls extends to opposite lateral sides of the mobile workstation.

Detailed Description

Fig. 1 shows a mobile workstation 2 according to the invention in a first preferred embodiment. The workstation 2 comprises a mobile vacuum cleaning apparatus 4 and a storage unit 6, the storage unit 6 being attached to the mobile vacuum cleaning apparatus 4.

The vacuum cleaning apparatus 4 is similar to a conventional vacuum cleaner used by home or hobby tradesmen, except that the vacuum cleaning apparatus 4 is generally more powerful and more efficient in terms of air throughput, dust capacity and filtration efficiency. The vacuum cleaning apparatus 4 comprises a housing which, in this embodiment, is made up of two

parts

8, 10. The first bottom part 8 of the housing can have the form of a dust and debris collecting chamber and is adapted to receive a primary filter element (not shown), for example in the form of a vacuum cleaner bag made of paper or fabric. The bottom part 8 of the housing is provided with wheels 12 in order to enable the vacuum cleaning apparatus 4 to move freely over the floor 14 of the space where it is used. The mobility of the workstation 2 is thus achieved by means of the wheels 12 of the mobile vacuum cleaning device 4. Furthermore, the bottom part 8 of the housing comprises at least one air inlet opening 16 for the attachment of a first end of at least one vacuum hose 18 for sucking dust laden air from a hand held power tool 20, for example from a sander, grinder or polisher. The opposite end of the vacuum hose 18 is connected to the power tool 20, and in particular to the active or passive suction device of the power tool 20.

In this embodiment, the second top part 10 of the housing comprises an electric or pneumatic drive (not shown) for generating a vacuum in order to draw dust-laden air into the chamber formed by the bottom part 8 of the housing via the vacuum hose 18. The drive means can comprise one or more electric or pneumatic motors and turbines. The top part 10 of the housing can be releasably attached to the bottom part 8 of the housing, for example by means of a quick-release clamping element 22. Furthermore, the top part 10 of the housing can comprise electric and/or pneumatic input and output means for controlling the operation of the vacuum cleaning device 4, such as buttons, rotary switches 24 and/or power sockets 26, pneumatic sockets 28.

Furthermore, the mobile workstation 2 comprises a storage unit 6, the storage unit 6 being attached to the mobile vacuum cleaning device 4 and being adapted to store hand-held power tools, such as power tools 20, accessories for power tools (e.g. different back pads, tools for releasing and securing back pads, tools for detaching sandpaper or polishing pads from a backing pad), consumables for power tools (e.g. sandpaper, polishing pads, abrasive paste, rechargeable batteries) and/or other items (e.g. conventional tools such as screwdrivers, hammers, or cloths, sponges). The storage unit 6 can include a storage rack (e.g., rack 80), receptacles (e.g., sections 40, 46) for containers (e.g., container 42), a chamber, a tissue holder (e.g., tissue holder 100), a support arm (e.g., support arm 88) for supporting the vacuum hose 18 of the mobile vacuum cleaning apparatus 4, all of which are described in further detail below. According to the present invention, it is proposed that the top part 30 of the top part 10 of the housing of the mobile vacuum cleaning device 4 comprises at least one movable part 32 adapted to be moved between a closed position and an open position. The at least one movable member 32 forms a receiving chamber 33 (see fig. 5-9) adapted to receive a hand-held power tool, an accessory for a power tool, a consumable for a power tool, and/or other items when the movable member 32 is in its open position.

In the embodiment of fig. 1, there are two movable parts 32 in the form of cover elements 32', the cover elements 32' being adapted to hinge between a closed position (see fig. 1 to 4) and an open position (see fig. 5 to 9) about a first hinge axis 34 extending in a substantially horizontal plane. Preferably, the first hinge axis 34 of the cover element 32 'extends in a horizontal plane parallel to the longitudinal extension of the mobile work station 2, so that the cover element 32' can be hinged to a lateral side of the housing. Two cover elements 32 'are hinged to both lateral sides of the housing to provide a symmetrical design with respect to the longitudinal extension of the mobile station 2 when the cover elements 32' are in their closed position and when they are in their open position.

Preferably, the or each cover element 32' has an outer side surface 36 adapted to lie against a lateral side surface 38 of the housing of the mobile vacuum cleaning device 4 when the or each cover element 32' is in its open position, with the first hinge axis 34 being located between the outer side surface 36 of the cover element 32' and the lateral side surface 38 of the housing. This provides a very stable and robust storage compartment 33 when the cover element 32' is in its open position (see fig. 5 to 9).

Preferably, the top portion 30 of the housing of the mobile vacuum cleaning apparatus 4 comprises a first receiving portion 40 (see fig. 1) adapted to receive and secure at least one container 42 (see fig. 2-4) when the at least one movable part 32 is in the closed position. For example, the container 42 is implemented as a separate entity from the mobile vacuum cleaning apparatus 4. In particular, the container 42 is preferably of a standard type, such as that of Tanos GmbH, a German company

However, any other container 42 can be used. It is possible to receive and fix only one container 42 to the first receiving portion 40 of the housing. Alternatively, it is also possible to be able to receive two smaller containers 42 (with half the footprint of the containers mentioned earlier) and fix them to the first receiving portion 40 of the housing. Finally, it is also possible to attach a plurality of containers 42 (with the same or different footprint dimensions) on top of each other to the first receiving portion 40.

The first receiving portion 40 is accessible when the at least one movable member 32 is in its closed position, and at least one container 42 can be received and secured at the first receiving portion 40, the first receiving portion 40 being disposed on the top 30 of the top member 10 of the housing. Thus, the first receiving portion 40 on the top 30 of the housing has a substantially flat or planar extension, which substantially corresponds to the bottom surface of the container 42. Further, depending on the type of container 42 to be received and secured, the first receiving portion 40 can be provided with a recess 44 and/or a protrusion (not shown) for positioning and holding the container 42 in a predetermined position. Finally, still depending on the type of container 42 to be received and secured, the first receiving portion 40 can be provided with securing means (not shown) for releasably attaching the container 42 to the top part 10 of the housing. Alternatively, fastening means can also be provided at the bottom region of the container 42 in order to interact with corresponding elements on the first receptacle 40 and/or the top 30 and/or the top part 10 of the housing.

Preferably, the top portion 30 of the housing of the mobile vacuum cleaning apparatus 4 comprises a second receiving portion 46 (see fig. 5) adapted to receive and secure the at least one container 42 (see fig. 7 and 9) when the at least one movable part 32 is in its open position. The container 42 is embodied as a separate entity from the mobile vacuum cleaning apparatus 4. Further, the container 42 is preferably of a standard type, such as Tanos GmbH, a German company

When the at least one movable member 32 is inThe second receiving portion 46 is accessible when in its open position and provides the storage compartment 33, and is capable of receiving at least one container 42 and being secured at the second receiving portion 46. The second receiving portion 46 can be identical to the first receiving portion 40 (see fig. 10). However, it is preferred that the first receiving portion 40 and the second receiving portion 46 are different from each other. The second receiving portion 46 has a substantially flat extension, which corresponds to the bottom surface of the container 42. Furthermore, depending on the type of container 42 to be received and secured, the second receiving portion 46 can be provided with a recess 48 and/or a protrusion (not shown) for positioning and holding the container 42 in a predetermined position. Finally, still depending on the type of container 42 to be received and secured, the second receiving portion 46 can be provided with securing means (not shown) for releasably attaching the container 42 to the top part 10 of the housing when the at least one movable part 32 is in its open position. Alternatively, the fastening device can also be provided on the container 42.

According to yet another preferred embodiment of the invention, it is proposed that the top part 30 of the top part 10 of the housing of the mobile vacuum cleaning apparatus 4 comprises a third receiving portion 50 (see fig. 5) adapted to receive and fix at least one partition wall 52 (see fig. 8) when the at least one movable part 32 is in its open position. According to this embodiment, by the at least one movable member 32 being in its open position, the storage unit 6 not only provides one or more storage compartments 33, but also provides the possibility of attaching the partition wall 52 for storing hand-held power tools 20, accessories for power tools, consumables 55 for power tools, and/or other items. The partition wall 52 can thus be provided with a shelf, a hook 54 and a retainer. In the embodiment shown in fig. 8, hooks 54 are provided for consumables 55, the consumables 55 being in the form of sandpaper, which may have different particle sizes or particle sizes. The partition wall 52 can be embodied as a perforated plate with a plurality of holes 56, the holes 56 preferably being distributed uniformly with respect to each other along the entire plate 52. The rack, hooks 54, and holders can then be individually positioned and attached to the perforated plate 52 using one or more holes 56. The partition wall 52 is made of plastic or metal. When not in use, the partition wall 52 is stored in another position, preferably as part of the mobile station 2, for example in a separate storage compartment 58 (see fig. 4 and 7), which storage compartment 58 is arranged between two vertical rods 60 of a handle 62 of the mobile station 2. The third receiving portion 50 can be an integral part of the second receiving portion 46, enabling the container 42 or the dividing wall 52 to be selectively received and secured by the top portion 30 of the housing when the at least one movable member 32 is in its open position.

Preferably, the third receiving portion 50 of the housing of the mobile vacuum cleaning apparatus 4 comprises two rails 64 (see fig. 5 and 8), each rail 64 being adapted to be hinged between a folded position (see fig. 5) and an unfolded position (see fig. 8) about a second hinge axis 66 extending in a substantially horizontal plane, such that the rails 64 in the unfolded position face each other, and the partition wall 52 is insertable into and retainable by the rails 64. It is proposed that the top 30 of the top part 10 of the housing comprises a recess (not shown) for receiving the guide rail 64 in its folded position (see fig. 5) so as to form a flat surface of the second receiving portion 46. Thus, when the rail 64 is in its folded position, the at least one container 42 can be received and releasably attached to the second receiving portion 46. When there is no container 42 received and attached to the second receiving portion 46, the rails 64 can be hinged into their deployed position, and the dividing wall 52 can be inserted into the rails 64 and retained by the rails 64 (see fig. 8). The guide rails 64 have a substantially vertical extension in their deployed position, so that the partition wall 52 inserted therein also has a vertical extension which is substantially perpendicular to the horizontal extension of the second receiving portion 46.

In addition to the hinged lid 32' shown in fig. 1 to 8, the at least one movable part 32 of the top 30 of the top part 10 of the housing can have many different embodiments in order to provide at least one storage compartment 33 when the at least one movable part 32 is in its open position. For example, in the embodiment of fig. 10, it is proposed that the at least one movable member 32 is in the form of at least one drawer 32 "adapted to be moved in a substantially horizontal plane between a closed position and an open position by means of at least one linear guide element 68. Preferably, the at least one linear guide element 68 has a horizontal extension. It is proposed that each drawer 32 "is assigned two linear guide elements 68. Linear guide elements 68 are provided on the outer surfaces of two opposite lateral sides 70 of the drawer 32 ".

According to yet another alternative embodiment, illustrated in fig. 11, the at least one movable part 32 is in the form of a cover element 32 "'adapted to be moved between the closed position and the open position by means of a guiding mechanism 72, the guiding mechanism 72 acting between the at least one cover element 32"' and the rest of the top part 10 of the housing of the mobile vacuum cleaning apparatus 4. In the embodiment of fig. 11, there are four cover elements 32 "'that are movable relative to the top part 10 of the housing, two cover elements 32"' on each side of the housing. Preferably, the guide mechanism 72 comprises at least two guide rods 74, the guide rods 74 being on opposite sides of the at least one cover element 32 "'and providing translational movement of the at least one cover element 32"' between the closed position and the open position. In the embodiment shown, each side of the top part 10 of the housing has two cover elements 32 "', with three guide rods 74 arranged on opposite sides of the cover elements 32"'. When the at least one cover element 32 "'is in its open position, an outer side surface of the at least one cover element 32"' can be placed against a lateral side surface 38 of the top part 10 of the housing of the mobile vacuum cleaning apparatus 4. Optionally, the bottom surface of the at least one cover element 32 "' can be placed against the top part 10 of the housing or the top surface of another cover element 32" ' provided below the cover element 32 "'.

It is also suggested that the mobile work station 2 comprises a handle 62 adjustable between an insertion position and a plurality of extracted positions, the handle 62 comprising a handlebar 76 adapted to be gripped by a user in order to move the mobile work station 2 freely on the floor 14 of the space. The handlebar 76 is height adjustable by withdrawing and inserting the stem 60 of the handle 62. The handlebar 76 is fixable in at least one extracted position. Preferably, the handle 62 has two telescopic bars 60 having a substantially vertical extension and wherein the bottom ends of the bars 60 are attached to the mobile vacuum cleaner 4 or the bottom part 8 of the vacuum cleaner 4, respectively. The fixing of the handlebar 76 in the desired extracted position is achieved by means of a quick locking or quick clamping mechanism 78. An advantage of the height-adjustable handle 62 is that the handle 62 can be inserted if the mobile work station 2 is not used and/or if no handle 62 is required, so that only very little space is required.

Preferably, at least one storage rack 80 is attached to the handle 62 in a manner foldable about a substantially horizontal folding axis 82. The storage rack 80 is adapted to be folded about a horizontal folding axis 82 between a rest position (see fig. 1 and 2) and a working position (see fig. 3 to 9). When the storage rack 80 is not needed, it can be brought into the rest position, so that only a very small space is required, for example between the vertical bars 60 of the handle 62. When one or more storage shelves 80 are needed, they can be folded into their operative positions to provide additional storage space for the hand-held power tool 20, accessories for the power tool, consumables 55 for the power tool, and/or other items. The at least one storage rack 80 is adapted to be held and/or secured in its operative position. When the storage rack 80 is in its working position, one or more support rods 84 can be brought into a supporting position below the storage rack 80, thereby supporting and maintaining the storage rack 80 in the working position. In particular, the support bar 84 can be hinged about a third hinge axis 86 into a support position below the storage rack 80. The third hinge axis 86 extends substantially perpendicular to the horizontal folding axis 82 of the storage rack 80. The upper support surface of the support bar 84 in its support position extends substantially in the same plane as the bottom surface of the storage rack 80 in its operative position. The at least one storage rack 80 is preferably attached to both vertical bars 60 of the handle 62, in particular to the extractable element of the vertically telescopic bars 60 of the handle 62, so that the height of the at least one storage rack 80 can be adjusted together with the height adjustment of the handlebar 76.

Furthermore, it is proposed that the mobile workstation 2 comprises at least one support arm 88 which is rotatable about a substantially vertical first axis of rotation 90. The support arm 88 has an upper portion 92, the upper portion 92 having a substantially horizontal extension, and the support arm 88 is adapted to support the vacuum hose 18 of the mobile vacuum cleaning apparatus 4. The at least one support arm 88 is preferably attached to the handle 62, in particular to the extractable element of the vertically telescoping rod 60 of the handle 62, and can be height-adjusted together with the handle 62. Alternatively, the support arm 88 can also be attached to a stationary part of the housing, preferably to the bottom part 8 of the housing, or to a stationary telescopic element of the vertically telescopic rod 60 of the handle 62, with which the handle 62 is attached to the housing, preferably to the bottom part 8 of the housing. The support arm 88 can comprise a clamping element 94 for releasably attaching the vacuum hose 18 of the mobile vacuum cleaning apparatus 4.

According to another preferred embodiment, it is proposed that the mobile workstation 2 comprises at least two support legs 96, each support leg 96 being adapted to be moved between a folded position (see fig. 1 to 4), in which it is placed against a side of the housing of the mobile vacuum cleaning apparatus 4, and an unfolded position (see fig. 5 to 9), in which it extends away from the side of the housing of the mobile vacuum cleaning apparatus 4. The distal ends of the support legs 96 each include a height adjustable support element 98 so as to be able to be brought into contact with the floor 14 on which the mobile workstation 2 stands when the support legs 96 are in their deployed position. The support legs 96 provide high stability of the mobile workstation 2 during the intended use of the mobile workstation 2. In its collapsed position with the support members 98 retracted, the support legs 96 require only a very small amount of space. In its deployed position with extended support members 98, support legs 96 increase the standing surface of mobile workstation 2. The support legs 96 are preferably attached to the bottom part 8 of the housing, in particular to the vertical bars 60 of the handle 62, which vertical bars 60 are attached to the bottom part 8 of the housing.

The support legs 96 are rotatable about a second vertical axis of rotation 99 to move the support legs 96 between the folded and unfolded positions. The vertical second axis of rotation 99 extends substantially parallel to the vertical first axis of rotation 90 of the support arm 88. In the embodiment shown in the figures, the support member 98 is attached to the distal end of the support leg 96 by means of a vertical threaded connection. In that case, the support member 98 can be retracted and extended in the vertical direction by rotating it in a threaded connection relative to the distal end of the support leg 96. Optionally, the support element 98 can also be attached to the distal end of the support leg 98 by means of a linear guide mechanism for enabling vertical linear movement of the support element 98 into a desired vertical position relative to the distal end of the support leg 96 in conjunction with a quick release clamping element for securing the support element 98 in the desired vertical position. Furthermore, it is also possible to rotate the support elements 98 about a substantially horizontal axis with respect to the respective support legs 96 to which they are attached, in order to increase the ground clearance and avoid the support elements 98 contacting the ground when the mobile workstation 2 is moved over the ground by means of the wheels 12.

According to yet another alternative (not shown in the figures), it is proposed that the support legs 96 are rotatable about a second axis of rotation 99, the second axis of rotation 99 having an extension that is slightly inclined with respect to the vertical extension, so that the support legs 96 are movable between the folded position and the unfolded position. The support member 98 is fixed to the distal end of the support leg 96 at a predetermined position. The inclination of the second axis of rotation 99 is such that the support element 98 is automatically lowered when the support legs 96 are brought into the unfolded position, and the support element 98 is automatically raised when the support legs 96 are brought into the folded position. Thus, in this alternative embodiment, the support member 98 is automatically retracted and extended in the vertical direction by moving the support legs 96 between the folded and unfolded positions.

Similar to the support arm 88 for the vacuum hose 18, a tissue holder 100 can be provided at the other vertical bar 60 of the handle 62. The tissue holder 100 can be height adjustable along with the handle 62. Further, the tissue holder 100 is rotatable about a substantially vertical rotation axis extending parallel to the vertical first rotation axis 90 of the support arm 88. The tissue holder 100 can include a horizontal portion (not visible in the figures) for receiving and carrying a tissue roll 102. The distal end of the horizontal part of the tissue holder 100 is provided with a stop element 104. To provide for easy and quick replacement of an empty roll of tissue 102 with a new roll of tissue, a stop element 104 can be releasably attached to the distal end of the horizontal portion of the tissue holder 100. The stop element 104 can be provided with an upwardly facing concave arcuate receiving portion 106 for receiving at least a portion of a power tool, such as the power tool 20, and maintaining the power tool ready for grasping by a user of the mobile workstation 2 (see fig. 3). Instead of the paper towel holder 100, the mobile workstation 2 can also be provided with a second support arm, similar to the support arm 88, for a second vacuum hose.

Furthermore, according to another preferred embodiment, it is proposed that at least one wing wall 108 is attached to the mobile workstation 2 in a manner foldable about a substantially vertical folding axis 110. The embodiment shown in the figures comprises two wing walls 108, each wing wall 108 being adapted to fold about this vertical folding axis 110 between a rest position (see fig. 4) and a working position (see fig. 5 to 9). The wing wall 108 is preferably attached to the vertical post 60 of the handle 62, in particular to the extractable element of the telescopic rod 60 of the handle 62, so that the height of the wing wall 108 can be adjusted together with the height adjustment of the handlebar 76. The wing wall 108 is preferably implemented as a perforated plate with a plurality of holes 112, the holes 112 preferably being evenly distributed with respect to each other along the entire plate 108. The shelf, hooks (corresponding to hooks 54), and retainer 114 can be individually positioned and attached to the perforated sheet 108 using one or more apertures 112. The holder 114 can be implemented similar to the stop element 104 of the tissue holder 100 with a concave arcuate receiving portion 106 for receiving and holding a power tool, such as the power tool 20. The wing walls 108 are made of plastic or metal.
