Accordingly, in one embodiment, the rollator has a control which, in particular hardware and / or software technology, for controlling at least one, in particular electrical, functional element of the rollator, in particular

at least one drive and / or at least one brake of the chassis, based on or depending on one, in particular by the or the

Detection means, detected position or movement of the transport container and / or the storage surface is set up. Further advantages and features emerge from the subclaims and the exemplary embodiments. This shows, partially schematized:

1 shows a meridian section through a rollator according to an embodiment of the present invention;

Fig. 2: the rollator in Fig. 1 corresponding view with horizontal

shifted transport container;

3 shows the rollator in a plan view with the transport container shifted horizontally to the front and the cover surface displaced laterally to the right; and

Fig. 4: the rollator in Fig. 2 corresponding view with the transport container in a seat covering a position and laterally shifted to the left cover surface.

Fig. 1 shows a meridian section through a walker according to an embodiment of the present invention.

The rollator has a motorized chassis 10 with a plurality of driven wheels 1 1 and handles 12.

Next, the rollator on a transport container 20 which by a

Linear guide 23 is mounted in a degree of freedom x manually displaceable on the chassis 10 (see Fig. 2).

The degree of freedom x is parallel to a footprint of the chassis 10 or in horizontal standing chassis to the horizontal (horizontal in Fig. 1). The straight axis of the linear guide 23 forms with the footprint and a

Forward direction or median plane of the chassis in each case an angle which is at most 15 °. In other words, the transport container 20 is in

Substantially in forward-backward direction (left-right in Fig. 1, 2) displaceable (stored). Next, the rollator has a substantially flat storage surface or plate 30, on.

This is mounted by a linear guide 31 in a degree of freedom y manually displaceable on the transport container 20 (see, Fig. 2-4). As a result, the mobility x of the transport container 20 can advantageously also provide one degree of freedom of the depositing surface 30 and additionally serve as a closure or cover of the transport container.

The storage surface 30 is thus mounted by the guide 23, 31 in the two degrees of freedom x, y manually displaceable on the chassis 10 The degree of freedom y is the footprint of the chassis 10 or horizontally stationary chassis to the horizontal (horizontal in Fig. 1) also parallel. The straight axis of the linear guide 31 forms with the footprint and a

Transverse direction or frontal plane of the chassis in each case an angle which is at most 15 °. In other words, the support surface 30 is substantially in the left-right direction of the rollator or laterally (top-bottom in Fig. 3, 4) displaceable (stored).

In a modification, not shown, the transport container 20 is at the

Chassis 10 and / or the storage area 30 on the transport container 20th

pivotally mounted, in particular about an axis of rotation, with the

Footprint of the chassis includes an angle which is at least 75 °. This also makes it possible to provide a horizontal degree of freedom.

Next, the walker on a connected to the chassis 10, substantially parallel to the footprint of the chassis seat surface 40. The seat surface 40 has a first region 41 and a second region 42, which can alternatively be covered and released by opposing movements of the transport container 20, as can be seen in FIG. Thus, by oppositely moving the transport container 20 in the front-to-rear direction optionally the first or second region of the seat can be released, so that the seat 40 can be used either from the front or rear. In a covering position of the shown in Fig. 1

Transport container 20 covers this 100% of the seat 40 from.

The transport container 20 has an ergonomically shaped front side wall 21 and an ergonomically shaped rear side wall 22, the backrests to the released from the transport container 20 area 42 and 41 form.

The rollator has two mechanical stops 50 for limiting both sides of an opposite movement of the transport container 20 in its degree of freedom x. In addition, it has two mechanical stops 60 for limiting both sides of an opposite movement of the support surface 30 in its degree of freedom y relative to the transport container 20.

In addition, the rollator has a manually and / or by a controller 80 actuated detent 50 for fixing the transport container 20 in the cover position shown in Fig. 1, in which the transport container 20 covers 100% of the seat 40, and / or in a in Fig. 2, in which it exposes the second area 42 and covers the first area 41, and / or in a position shown in dashed lines in FIG. 2, in which, conversely, it releases the first area 41 and covers the second area 42. This lock is in

Embodiment formed with the stops 50 and therefore identified by the same reference numeral. In a modification not shown can

Locking and stops also be spaced from each other.

Additionally or alternatively, the rollator has a manual and / or by the

Control 80 actuated lock 60 for fixing the shelf 30 in a plurality of variable or discrete positions, of which in Fig. 3, 4th

two positions are shown by way of example, in which the storage surface 30 is displaced to the left or right and each one (filling) opening of the transport container 20 releases. In particular, the storage surface 30 can be determined by the lock 60 in a covering position in which this closes or covers the (filling) opening of the transport container. This lock is in Embodiment formed with the stops 60 and therefore identified by the same reference numeral. In a modification not shown can

Locking and stops also be spaced from each other.

Furthermore, the rollator has a detecting means 50 for detecting the covering position of the transporting container 20 above the seating surface 40 and a detecting means 60 for detecting the covering position of the depositing surface 30 above the (filling) opening. This detection means are formed in the embodiment with the stops or detents 50 and 60 and therefore identified by the same reference numeral. In a modification, not shown, detection means and locking or stops can also be spaced from each other.

In operation, the user can if necessary the transport container 20 from the

Fig. 1) move forward or backward (see Fig .. 2) and so areas of the seat 40 from the rear or front board.

By moving the storage surface 30 on the transport container 20 to the left or right (cf., Fig. 3, 4) and / or the transport container 20 forward or backward, he can advantageously position the tray 30, in particular on a Tischkahte or the like vorzuschieben, and / or open or close the (filling) opening of the transport container 20.

The controller 80 detects, via the detection means 50, whether the front portion 41 of the seat 40 is released by the transport container 20, and in this case closes brakes of the chassis 10, so that the user can sit down safely.

The controller 80 also detects via the detection means 50 whether the rear portion 42 of the seat 40 is released by the transport container 20, and in this case releases drives of the chassis 10, so that the user can use it as an electric wheelchair.

The controller 80 also detects via the detection means 60 whether the (filling) opening of the transport container 20 is released by the storage surface 30, and activates an interior lighting of the transport container 20 by way of example in this case. The storage surface 30 has a circumferential and ergonomically shaped handle 70. As a result, it can, in particular in conjunction with the detents 50, 60, advantageously function as a secure stand-up aid

Although exemplary embodiments have been explained in the foregoing description, it should be understood that a variety of modifications are possible. It should also be noted that it is the exemplary

The explanations are merely examples of the scope of protection

Applications and the structure should in no way limit. Rather, the expert is by the preceding description a guide for the

Implementation of at least one exemplary embodiment given, wherein various changes, in particular with regard to the function and arrangement of the described components, can be made without departing from the scope, as it is apparent from the claims and these equivalent
