[0027] FIG. 12 shows the rear rolling device from FIG. 11, at a different angle to the deck;

[0028] FIG. 13 shows the brake lever of a kick scooter according to the invention from FIG. 1 or FIG. 5 in a side view;

[0029] FIG. 14 shows the brake lever from FIG. 13 in a view from the rear;

[0030] FIG. 15 shows the brake lever from FIG. 13 in a diagonal view; and

[0031] FIG. 16 shows the brake lever from FIG. 13 in a view from above.

[0032] A kick scooter 100 according to the invention having a deck 101 and a handlebar 102 is shown in FIGS. 1 to 4. Furthermore, the kick scooter 100 has a rear rolling device 103 and a front rolling device 104. A bracket 105 having a bearing bush 106 is fixedly connected to the deck 101. The handlebar 102 is guided through the bearing bush. To achieve a steering capability, the front rolling device 104 is embodied as a single wheel, which is arranged on the handlebar 102. The rear rolling device is arranged on the side of the deck facing toward the ground in the usage position.

[0033] The rear rolling device 103 has seven rollers 107, which are arranged essentially adjacent to one another on a carrier element 108. The carrier element 108 is embodied as circularly curved. Each roller 107 has a recess in its axle for accommodating a roller bearing for guiding through the carrier element. Each roller is essentially normal to the tangent which leads through the center line of the carrier element at the point of the center of the roller 107.

[0034] Another embodiment variant 200 is shown in FIGS. 5 to 8, wherein equivalent parts have identical reference signs. This embodiment variant is also designed for athletic transportation. For this purpose, a joint 215 is arranged in the bracket 105. This enables the handlebar 102 to be collapsed parallel to the deck, in order to enable simpler transportation and storage. To enable an even more compact form, the handlebar 102 is shaped narrower and is embodied so it can be divided. In addition, a brake lever 111 is pivotably connected to the deck 101 in the region of the rear rolling device 103 for safer riding.

[0035] The rear rolling device 103 is shown in detail in FIG. 9. The wheels are embodied rounded to ensure optimum driving dynamics. By way of explanation, an axle 107a of a roller 107 is shown, which forms a tangent at a center line 103a, which connects the center points of the rollers 107 to one another.

[0036] An alternative embodiment of a rear rolling device 207 is shown in FIG. 10. In this case, barrel-shaped rollers 207 are arranged on the carrier element 108. This enables substantially less wear. In the two above-mentioned embodiment variants, roller bearings 109 are arranged in the rollers 107 or 207, respectively. The axles 207a are also tangents on the center line 203a here and enclose an angle 217, which is approximately 12.

[0037] A plane 110, which is formed by the axles of the rollers 107 of the rear rolling device 103, is shown in FIG. 11 and FIG. 12. In FIG. 11, this plane is perpendicular to the deck 101. This enables pleasant riding dynamics, similarly to a wide rear tire. In FIG. 12, the plane is inclined to the rear. A feeling of sliding to the side can thus be generated. The carrier element 108 is preferably pivotably connected to the deck 101 to enable individual adaptation.

[0038] FIGS. 13 to 16 show the brake lever in detail. The brake lever has an actuating surface 112 and a friction block 113, wherein the friction block 113 has at least one curved friction surface 114 adapted to the shape of the carrier element 108. A force distributed uniformly onto all rollers is thus transmitted upon actuation of the brake via the actuating surface 112. The braking action is thus constant, independently of the roller presently touching the ground.
