BRIEF DESCRIPTION OF THE DRAWINGS

[0016] FIG. 1 shows an embodiment of a device according to the disclosure.

[0017] FIG. 2 shows a further embodiment of a device according to the disclosure.

DETAILED DESCRIPTION

[0018] As required, detailed embodiments of the present disclosure are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the disclosure that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present disclosure.

[0019] The illustration of FIG. 1 shows an embodiment of the disclosure, which has a mobile transport device 1 with a chair-like seat unit 2a, which is in particular a chair-like seat unit 2a of a motor vehicle. The device 1 has four leg-like mobility fittings 3.

[0020] The chair-like seat unit 2a has typical components of a chair, e.g. a seat surface 5, a head rest 6. Furthermore, operating devices 7 for operating or inputting commands for movement are arranged on the chair-like seat unit 2.

[0021] The leg-like mobility fittings 3 each have a first part 3a and a second part 3b, which are connected to one another by a hinge-like unit 3c. The part 3a is connected to the chair-like seat unit 2a by way of a similar hinge-like unit 3d. As an alternative to the illustrated two-part embodiment of the leg-like mobility fittings 3, these can also be sub-divided into even more parts, e.g. have three or four parts overall. The foot regions 3e of the leg-like mobility fittings 3 can also have expansions, which increase the stability of the device 1 when stationary and also when moving, as well as increase the all-terrain access by counteracting sinking into soft ground, for example.

[0022] The leg-like mobility fittings 3 can be driven in particular electrically, but also however, for example, hydraulically. The device 1 has at least one drive unit 8 for driving the leg-like mobility fittings 3. In FIG. 1, a drive device 8 is arranged in the chair-like seat unit 2 in the region of the connection 3d of the leg-like mobility fittings 3 to the chair-like seat unit 2, which directly enable the movement of the leg-like mobility fittings 3. Alternatively, a central drive device can also be arranged in or on the chair-like seat unit 2a.

[0023] The leg-like mobility fittings 3 are designed to move independently of one another. The movement of the leg-like mobility fittings 3 can also be undertaken in a coordinated manner. In order to coordinate the movements of the leg-like mobility fittings 3, a control unit 9 is provided, which is arranged in the region of the chair-like seat unit 2a, for example inside or underneath the seat surface 4.

[0024] The device 1, furthermore, has a row of sensors 10, which are likewise connected to the control unit 9. The sensors are designed in particular for detecting orientation and speed of the device 1. The sensors 10 may comprise, inter alia, a gyroscope, which may be used for the active position regulation of the device 1. The control unit 9 detects the sensor values and sends corresponding control commands to the drive device 8 in order to balance the device 1 by moving the leg-like mobility fittings 3. The control unit 9 comprises a sub-unit designed for balancing the device 1. Alternatively, a separate second control unit can be provided (not shown), which is provided solely for balancing the device 1.

[0025] Using the operating devices 7, a person seated on the seat surface 4 can impart manual control commands that are processed by the control unit 9 and forwarded to the leg-like mobility fittings 3. The control unit 9 can also be connected by a wireless communication to a remote control device through which the control commands can be imparted to the device 1.

[0026] The leg-like mobility fittings 3 are designed so that they can be collapsed and brought into a rest position underneath the chair-like seat unit 2a. If the leg-like mobility fittings 3 are in a rest position underneath the chair-like seat unit 2a, the parts 3a and 3b are located substantially parallel to the floor and to the seat surface 4 of the chair-like seat unit 2a.

[0027] The device 1 is designed to be moved into or out of the vehicle on the basis of corresponding control commands. In the ideal case, the device 1 is moved into or out of the vehicle with a person sitting on the seat surface 4. In order to exit the vehicle, the leg-like mobility fittings 3 are moved out of the rest position in a coordinated sequence of movements controlled by the control unit 9 so that they lift up or raise the chair-like seat unit 2a, and the device 1 is moved out from the vehicle by a coordinated movement of the leg-like mobility fittings 3. In other words, the movement of the device 1 can be pre-set so that the device 1 runs from the vehicle. If the device 1 is fixed by means of a mechanism for engaging in the vehicle, then where necessary a horizontally acting force has to be exerted on the part of the device 1 or the vehicle in order to move the device out from an engaged position.

[0028] Alternatively, the device 1 can be combined with a sliding unit. The device 1 can slide by means of the sliding unit at least partially out of the vehicle (or into same) before the leg-like mobility fittings 3 come into operation. Thus, secondary means can be used, for example units which support the device 1, before the leg-like mobility fittings 3 are fully in a working position. The term sliding unit embraces means that enable, for example, wheeling, particularly in combination with rails. It is here clear to the person skilled in the art how corresponding units function or are to be configured.

[0029] The device 1 can furthermore be movable in its circumferential direction relative to the vehicle floor so that it can be turned at least in part. The device 1 can thus be turned into a suitable position in the direction of a vehicle door for getting out so that the device 1 can be moved more easily out of (or into) the vehicle. It is clear to the person skilled in the art how corresponding units function or are to be configured.

[0030] In order to move the device 1 into the vehicle, the device is controlled so that it basically runs into the vehicle. At the place where the seat is to be locked, the leg-like mobility fittings 3 are moved in a coordinated sequence of movements controlled by the control unit 9 so that the chair-like seat unit 2a is let down onto the floor of the vehicle, wherein the device 1 is moved through a coordinated movement of the leg-like mobility fittings 3. For this, a horizontally acting force is to be exerted when necessary on the part of the device 1 or the vehicle in order to engage the device 1 in a corresponding unit. In other words, the movement of the device 1 can be pre-set so that the device 1 runs and is let down into the vehicle. The sliding units or turning units mentioned above can likewise be used when moving into the vehicle.

[0031] In a further embodiment according to the illustration of FIG. 2, the useful surface 2 of the device 1 has no seat unit but a loading surface 2b. Also in this embodiment, the device 1 has the features described above of a control unit, drive devices and sensors. The loading surface 2b is designed to be flat. The loading surface 2b is provided to transport a payload. The device 1 can have means in order to fasten a payload on the loading surface, e.g. straps. The control of the device 1 with the loading surface 2b is by remote control. The device 1 according to FIG. 2 is to be conveniently housed since it can be stowed, for example, on the rear shelf of a vehicle, the rear bench or in the trunk space and can be stored there by folding in the leg-like mobility fittings 3. When necessary the leg-like mobility fittings 3 are controlled so that the device 1 is raised and brought to a position where a payload 11 is to be arranged on the loading surface 2b.

[0032] While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms of the disclosure. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the disclosure. Additionally, the features of various implementing embodiments may be combined to form further embodiments of the disclosure.
