  • the front wheel 6 of the device is freely rotatably mounted on the fork arms 4, specifically about an axis perpendicular to the axis A1.
  • the two frame elements 2 are also connected to the rear end of the frame 1 which is remote from the bearing 3. Furthermore, a first, rear standing surface 7 is formed there on the frame 1, specifically by means of a plate fastened on top of the two frame elements 2.
  • two rear wheels 9 are freely and independently rotatable between the two frame elements on a shaft 8, which is perpendicular to the longitudinal extension of the frame elements 2 parallel there and both ends of which are each held on a frame element 2 stored.
  • the two wheels 9 have the same diameter and, in the embodiment shown, a slightly smaller diameter than the front wheel 6.

  • the frame elements 2 run in a straight line in the section 2 ′′ between the shaft 8 and the transition to the section 2 ′′.
  • the stand area 10 is located in this section 2 ′′.
  • the frame elements 2 form a section 2 ′′ ′′ at the rear end, on which these elements run obliquely upwards and on which the Stand area 7 are provided so that the latter is inclined with respect to the plane of the stand area 10.
  • the axis A lies in an imaginary central plane, which is arranged perpendicular to the plane of the standing surfaces 7 and 10 and includes the longitudinal axis L of the device, to which the frame elements 2 are also symmetrically symmetrical and closes an angle ⁇ of 90 ° or with the imaginary plane of the standing surface 10 less than 90 °, for example an angle ⁇ of 90 ° or less than 90 °, for example an angle ⁇ of 90-80 °, which opens towards the front of the device.
  • the axis A1 is also perpendicular to a plane including the axis of the wheel 6 and the longitudinal extent of the fork arms 4.
  • a mounting 11 for a rick 12 is also provided on the frame 1, as is also used for surfboards and which has a joint 13 which enables pivoting on all sides.

  • the device can also be used as a scooter, for which purpose a scooter handle is then inserted into the attachment 11 and fastened in a suitable manner becomes.
  • the wheels 6 and 9 are each spoke wheels with air tires.
  • the two wheels 9 ensure that the device is still standing on a flat surface, i.e. can be arranged with the central plane oriented in the vertical direction, in order to facilitate the ascent onto the device.
  • the stability of the device when driving straight ahead can be prevented by adjusting the angle ⁇ .
  • FIG. 4 shows a further possible embodiment of the rolling device according to the invention in a simplified representation.
  • This device consists of a frame 1a, which is essentially identical to the frame 1 of the device of FIGS. 1-3.
  • the front, steerable wheel 6 is again provided on the front of the frame 1a by means of the wheel carrier (wheel fork 5) which can be pivoted about the axis A1.
  • a wheel fork 19 is provided at the rear end of the frame 1a so as to be pivotable about an axis A4 which, like the axis A1, is a vertical axis which lies in the vertical central plane including the longitudinal axis L of the frame 1a and which is opposite to that of FIGS plane formed by both wheel axles A2 and A3 includes an angle ⁇ of 90 ° or less than 90 °, which opens towards the front of the device, ie for example an angle ⁇ in the range between 90 ° and 80 °.
  • the wheel fork 19 also has two fork arms 20, which are connected to one another via a yoke section and carry at their free ends the shaft 8, on which the two rear wheels 8 are freely rotatable between the two fork arms 20. At which connecting the two fork arms 20 together Yoke piece, the wheel fork 19 is pivoted about the axis A 4 to the frame 1a or to a bearing 21 there.
  • the distance between the two wheels 9 in the direction of the axis of the shaft 8 is again chosen so small in this embodiment that the two wheels 9 allow the device to be placed in an unstable equilibrium on a surface, but the device then tips over and thereby stopping when the user leaves the device during use.
  • the rear footprint 7 is omitted in this embodiment.
  • the device of FIG. 4 has a standing surface 10a with a larger dimension in the direction of the longitudinal axis L.
  • the driving properties of the device can be changed, i.e. by reducing the angle ⁇ , there is an increasing stabilization of the steering of the rear wheels 9.
  • the fork arms 4 and 20 of the wheel forks 5 and 19 each lie with their longitudinal extension in a plane that is perpendicular to the associated steering axis A1 and A4.
  • Fig. 5 shows an enlarged individual view of another possible storage for the two rear wheels 9 in such a way that these wheels can perform a limited amount of pivoting movement in the respective wheel plane RE according to the double arrow B, and that parallel to an axis to the longitudinal axis L for a corresponding inclination of these wheels with respect to the horizontal plane.
  • the wheels 9 are each mounted on a shaft 22 which is connected at both ends to the frame 1 by means of a bearing 23 and which has the function of the shaft 8.
  • the shaft or axle 22 is designed to be elastic, so that an inclination of the two wheels 9 is possible while deforming this elastic area.
  • the elastic region 24 is for example formed by a block made of an elastomer or by a spring arrangement.
  • the two bearings 23 are designed such that they enable the respective end of the axis 22 to pivot about an axis parallel to the longitudinal axis L of the rolling device and at least one bearing 23 also permits an axial displacement of the axis 22.
  • FIG. 6 shows an embodiment in which the two rear wheels 9 are mounted on an axle which forms a parallelogram arrangement 25 in their area 25 between the wheels 9, which also pivots the wheels 9 or their wheel planes RE by a predetermined amount around an axis parallel to the longitudinal axis L.
  • the parallelogram arrangement forming section 25 further has a resetting and damping element 27 formed by an elastic body, for example an elastomer, which is provided between the two arms 26 forming the parallelogram arrangement 25.
  • Fig. 7 shows a plan view of a suspension of the rear wheels 8 and 9 in such a way that these wheels are not mounted with their axle or shaft 8 directly on the frame 1, but on an auxiliary frame 28, which in turn with the help of hinge pin 29th is provided on the frame 1 so as to be pivotable about the longitudinal axis L, the two hinge pins 29 being provided with the same axes at the front and rear ends of the auxiliary frame 28 and with their axes lying in a plane intersecting the shaft 8 and arranged between the wheels 9.

  • a damping or restoring element 38 is in turn provided between the parallelogram arms 34.
  • the inclination of the wheels 9 enables safe and, above all, sporty driving on an inclined surface at an angle to the fall line.
  • a spring 39 is indicated very schematically as a functional element in FIG. 2, with which the front wheel 6 is rotated slightly from the zero position of its steering. When getting out and driving or controlling the device, the force of this spring is easily overcome or neutralized by the user.
  • the spring 39 causes the steering to turn so that the device immediately turns and then stops. This also makes it possible to make the distance between the rear wheels 9 adjustable in the axial direction, so that for beginners (even during training) the state of the device is improved by the greater distance between the two rear wheels 9 without the required self-locking or Braking (due to falling over) is lost in the event of a fall or accident.

  • the buffers and thus also the maximum steering deflection are adjustable in the embodiment shown.
  • the spring 39 acts between the bracket 45 and the bolt 43.
  • the handlebar 46 indicated in FIG. 2 can also be fastened to the frame 1 in order to enable driving with the roller board similar to a scooter, the handlebar 46 not causing the front wheel 6 to be steered, but in the case of the one shown Embodiment is rigidly attached to the frame 1 and only serves as a holder for the user.
  • the rear wheel arrangement so that it has more than two wheels 9 next to one another.
