Detailed description of an embodiment

The mobile computer workstation according to the invention can be pulled in a convenient manner like a luggage trolley, the term trolley is used below only as a designation for a suitcase or a bag or a backpack with wheels exclusively. However, it is clear to the person skilled in the art that the invention should not be limited to this term.

FIG. 1 schematically shows the structure of the trolley 10 according to the invention. In this case, the trolley 10 is shown unfolded as a seat workplace.

The support arm 12 serves as a central load-bearing element and is extendable in the direction of the double arrow A (telescopic), for example, designed as a hollow profile. However, it is clear to those skilled in the art that other profile shapes are possible as long as they are designed so that the profile of the support leg (see below) "disappears" in the contour of the load arm. Thus, for example, two parallel profiles can be provided, in the middle of the support foot can find space.

In this way, the support arm 12 can be adapted to the respective ergonomic requirements of the user. Furthermore, the support arm 12 (see below) may have an internal electrical and / or data-technical connection between a central unit 30 with a power supply and a storage surface 24. At its bottom end, the support arm 12 is provided with rollers 14 for mobile transport of the trolley 10, while at its upper end a support leg 16 is pivotally mounted (along the double arrow B) such that it can be pivoted into the contour of the Tragarmprofils. Also, the support leg 16 itself is telescopically formed (in the direction of the double arrow C), so that it ergonomically to the extract of the support arm 12 can be adjusted. At its bottom end of the support leg 16 carries a support member 18, which may for example consist of a tubular element with trained feet. Both the support arm 12 and the support leg 16 have known elements for locking, ie, for fixing their current position (not shown). As an additional anti-tipper, the support member 18 may be formed as a cross-beam.

On one side of the support arm 12, a seat member 20 is pivotally and slidably disposed (in the direction of the double arrows D and E), so that it can be ergonomically adjusted in height and tilt to the respective user. The seat member 20 can be folded when not in use in the contour of the support arm 12. The profile of the support arm 12 opens completely or partially in the direction of the rollers 14, similar to a tuning fork, so that the seat member 20 finds place between the two "forks". In the side view thus disappears the seat member 20 in the contour of the support arm 12th

The support arm 12 further has at its upper, telescopic end a swivel joint 22 for connecting a storage surface 24, which is prepared for receiving a mobile dialogue device 26 such as a notebook or a laptop or a docking station. With the help of the rotary joint 22, the shelf 24 can be rotated by angles up to 180 °. A pivoting along the double arrow F is possible. The storage surface 24 has on its one side an integrated handle element 28, which serves on the one hand for telescoping the support arm 12 and for inserting support arm 12 and folded support leg 16 and on the other hand for pushing, pulling or carrying the folded trolley 10 (see. Fig. 3 ). In addition, it is possible, with the aid of the grip element 28, to incline or turn the depositing surface 24.

In a particularly advantageous embodiment, the storage surface 24 can be transported separately in the transport container 34 and can be plugged onto the gripping element 28 as needed. In this case, the storage surface 24 is designed comparable to a docking station, which not only mechanically receives and fixes the dialog device 26, but at the same time also provides the electrical and data-related connections required for operation. Thus, by attaching the docking station (storage area 24) on the handle element 28 at the same time said connections to the Powerbox (see below) produced.

Of course, the shelf 24 but also only as a flat worktop for filing bspw. A writing pad can be formed.

Fig. 5 schematically shows the mounted on the handle member 28 shelf 24. The attached to the support arm 12 handle member 28 has two extendable (telescopic) halves 48, 50 and receiving points 36 for receiving the shelf 24. Furthermore, connection sockets 38, 40 for connecting the solar module 32nd (see below) and the dialogue device 26 are provided. The storage surface 24 also has guided in a receiving shaft 42 extracts 44, for example. As supports for bottles, ashtrays or the like. Usable. For this purpose, the extracts 44 have corresponding recesses 46. It is also possible to use the extracts 44, for example, as a shelf for display devices (eg computer mouse, etc.) and the like. In this case, the extracts 44 have no recesses 46. The extracts 44 may be located either only on one or both sides of the storage surface 24.

Advantageously, the inventive mobile variable computer workstation 10 has a power box 30 ("power box"), which is preferably attached to the support arm 12. These Powerbox 30 contains a 230V, 50Hz power supply via power cord and plug, preferably with an integrated cable rewind. Alternatively or additionally, it may have a central unit with corresponding batteries for temporary off-grid power supply of the devices to be supplied. The power box 30 preferably also has an adaptive power supply for providing the power supply for the connected devices, such as a mass storage, etc. on. It is coupled to the storage surface 24 by means of a data-technical connection (for example a conventional USB connection).

However, the power box 30 is not basically limited to elements for power supply, but may include a complete central unit, that is, a stand-alone computer. In this case, it is sufficient to position only a display with keyboard or a touch panel on the shelf 24, which communicates with the central unit in the power box 30. In this way, a "PC on wheels" would be feasible.

In a further advantageous embodiment of the trolley 10 according to the invention, a solar module 32 can be in a designated socket (see. FIG. 5 ) at the end of the handle and thus mechanically fix on the one hand and on the other hand contact electronically. The solar module 32 serves on the one hand for charging the batteries in the power box 30, on the other hand, it can also be used as a glare protection for the display of the dialogue device 26. Advantageously, therefore, the inclination angle of the module can be varied. Furthermore, it may have a backside LED illumination. This has the advantage that when using the invention in an industrial environment in which the necessary infrastructure is not yet developed, the invention can be used as a self-sufficient workspace. When not in use, the module 32 can be easily folded and stowed so easily in the transport container 34.

The transport container 34, which is detachably arranged on the support arm 12, preferably has an electrical through-connection to the power box 30, in order to hold devices or aggregates contained in the transport container 34, such as e.g. Cooling or heating elements to be able to drive. The transport container 34 can be designed as a travel or service case, bag or backpack. In a particularly advantageous embodiment, it is designed for use independently of the trolley 10, removable.

In Fig. 2 the inventive computer workstation 10 is shown unfolded as a standing workstation. The support leg 16 is as in Fig. 1 swung out and pulled out to a length required for the ergonomic headroom (telescoped). The seat member 20 is folded in this position in the contour of the support arm 12. According to the ergonomic requirements of a standing workstation, the support arm 12 is further extended, so that the grip element 28 can be tilted into the position suitable for this work position. The handle member 28 is rotated by 180 °, so that the integrated shelf 24 is in the same orientation (display directed to the user) as in the sitting position available. Depending on the ambient conditions, it is also possible in this form of use to plug the solar module 32 into the socket provided at the end of the handle in order to be able to illuminate the shelf 24 on the one hand, and to supply the power box 30 with energy, depending on the solar radiation.

Fig. 3 shows the computer workstation 10 according to the invention folded into a handy transport format. In this case, the support leg 16 as well as the seat member 20 is pivoted into the contour of the support arm 12 and thus takes up no space outside the overall contour of the trolley 10 a. The grip element 28 is also brought into a space-saving position.

The Fig. 4 shows the trolley 10 in a rolling position, as it is commonly used by the user on foot to be covered on foot paths.

In a further advantageous embodiment of the mobile computer workstation according to the invention, the movable elements can be driven entirely or at least partially electromechanically. In this way, the workplace according to the invention could be built up virtually independently after a corresponding command. Using corresponding menus on the dialogue device, the workstation could then assume user-defined positions and thus adapt optimally to the ergonomic needs of the current user that were once saved.

The achievable with the mobile variable computer workstation 10 according to the invention consist in particular that except a pure storage and transport aids a simple aufzubauender complete workplace with seating and storage space can be provided, the u.a. a comfortable operation of mobile dialogue devices while sitting or standing allows.

Further advantages are the folding or foldability of the trolley 10 or in its telescopic structure for easy and space-saving transport. Furthermore, the appropriately designed support structure allows a secure footing. Working and seat heights are ergonomically adjustable according to the relevant regulations for workplace design. In addition, rollers, preferably with a large diameter, allow easy running and a secure footing on uneven ground.
