  • the ski includes a central platform that is adjustable in height and longitudinal angle for fixing a respective skier's foot with the aid of a ski binding system.
  • a roller that can be rotated perpendicularly to the center platform is provided in each case.
  • the rotatable roller can align itself freely so that, depending on its rotational position, it enables rolling movements in any direction along the ground - including transverse to the longitudinal center axis.
  • a height difference between the fixed rollers and the rotatable rollers allows the skier to shift their weight or tilt the ski to switch between the fixed and rotating wheels, which should result in the driving feel and control characteristics of actual snow skiing.
  • the present invention has set itself the task of further developing the previously known personal transportation device in such a way that a personal transportation device results with improved driving feel and control properties that come even closer to actual snow skiing.

Furthermore, the at least one rolling arrangement has a braking device, by means of which a transverse braking force can be generated, which increases the rolling resistance of the transverse rolling device and thereby has a braking effect on rolling movements along the transverse axis. Finally, the lateral braking force can be changed by the person driving via the standing area.

  • the braking device is preferably designed in such a way that the transverse braking force is lowest, in particular zero, along the transverse axis into the locomotion device by the driving person in relation to the longitudinal center axis.
  • the braking device is designed in such a way that the lateral braking force increases with increasing inclination of the standing surface relative to the rolling arrangement or the rolling arrangements.

Furthermore, the axes of rotation of all longitudinal rolling devices run perpendicular to the longitudinal center axis in the basic position. Finally, the standing surface preferably extends parallel to the longitudinal central axis and parallel to the axes of rotation of the longitudinal rolling devices.

  • the pairs of roller assemblies 8 are attached to the platform 3 such that they can be pivoted about the associated steering pivot axis 35 such that the rotational position of the roller devices 15 about the steering pivot axis 35 can be adjusted as a function of the inclination of the platform 3 relative to the pairs of roller assemblies 8 .
  • FIG. 28 and 29 By way of example, a plan view of the front roller assembly pair 8 is shown without the platform 3 but with the support plate 12, wherein figure 28 the Rolling assembly pair 8 in the unloaded basic state, figure 29 with the platform 3 in an inclined state. It can be seen that the rolling devices 15 together with a bearing block 36 change their rotational position in relation to the steering pivot axis 35 depending on the inclination of the carrier plate 12 and thus of the platform 3 .
  • the bearing block 36 is used to support the rolling devices 15 about the overall axes of rotation 16 of the rolling devices 15.
  • the bearing block 36 also includes the brake cylinder 27 and brake piston 26 of the hydraulic braking device 14 of the rolling arrangement pair 8. It is connected via the pivot bearing 37 ( figure 30 ) mounted on the support plate 12 about the steering pivot axis 35.
  • a driver 38 attached to the carrier plate 12 causes the changes in the rotational position of the bearing block 36 depending on the inclination of the carrier plate 12.
  • Control cylinders 22 and control pistons 23 together with control profiles 13 of the braking device 14 are fastened to the support plate 12 or the platform 3 in a rotationally fixed manner about the steering pivot axis 35 .
  • the control cylinder 22 is connected to the brake cylinder 27 by means of a flexible hydraulic line 24 ( figure 31 ) tied together.
  • the roller ski 2 according to Figures 27 to 31 can be steered in addition to the control with the help of the variable transverse braking force to execute curves by the rotational position of the rolling devices 15 to the longitudinal center axis 7 can be changed or adjusted by changing the platform inclination in the manner of a conventional skateboard.
  • This additional control option leads to a driving behavior of the roller ski 2 that is even more similar to snow skiing and in particular to what is known as carving on snow.
  • a variant can be mentioned as an example, in which the lateral braking force is controlled electronically and by means of sensors (eg in the form of gyro sensors) which measure the inclination of the platform relative to the roller arrangement or the roller arrangement pair.
  • sensors eg in the form of gyro sensors
  • the personal mobility device according to the invention can also be equipped with an (electric) motor drive device, by means of which the mobility device can be driven in addition to, instead of and/or counter to a slope driving force.
  • an (electric) motor drive device by means of which the mobility device can be driven in addition to, instead of and/or counter to a slope driving force.
  • a braking force device can be provided, by means of which the person driving can brake the rolling movement along the longitudinal center axis.
  • a roller assembly is generally considered to be inventive that includes a first roller assembly that enables rolling movement along a first axis of movement and a second roller assembly that is superimposed on the rolling movement enabled by the first roller assembly along the first movement axis, a rolling movement along a second movement axis, which runs at an angle, preferably perpendicular, transverse to the first movement axis.
  • the rolling arrangement also has a braking device, by means of which a braking force can be generated which increases the rolling resistance of the second rolling device and thereby has a braking effect on rolling movements along the second axis of movement, the braking device comprising a control element which is used to adjust the braking force on the second rolling device acts, is pivotable about the first axis of movement of the first rolling device or an axis parallel thereto.
