Wheel suspension 16 arranged. The cover element 76 is arranged on the side of the receiving element 70 facing away from the front wheel suspension 16. The fastening element 78 extends through the cover element 76, the receiving element 70 and the respective end 58, 62 of the front suspension 16 and is on one of the respective fixing device 66, 67 facing end of the shaft 68 introduced and attached. In other words, the fastener 78 secures the cover member 76 and the receiving member 70 to the front suspension 16. The fastener 78 may be formed as a screw or bolt.

The blocking element 74 is arranged between the receiving element 70 and the cover 76. The receiving element 70 and the cover element 76 provide a guide for the locking element 74, so that the blocking element 74 can only be moved in the axial direction 69.

Between the receiving element 70 and the cover 76, an additional end of the respective longitudinal element 56, 57 facing the respective mounting device 60, 64 is additionally arranged. The two longitudinal elements 56, 57 each have a circular recess 81, which is arranged on one of the respective bearing means 60, 64 facing the end of the respective longitudinal element 56, 57. The blocking element 74 is arranged in the recess 81. A diameter of the recess 81 is greater than or equal, in particular substantially equal, the diameter of the locking element 74. The respective longitudinal element 56, 57 is thus rotatably mounted on the circumference of the locking element 74 about the longitudinal axis of the axis 68 of the front wheel 20.

The blocking element 74 has on the receiving element 70 side facing three

Locking lugs 75 which are arranged around a circumference of the locking element 74 radially outward. Preferably, the locking lugs 75 are spaced along the circumference of the locking element 74 at an angle of 120 ° symmetrically to each other. Each recess 81 has three locking grooves 82 which are formed complementary to the three locking lugs 75 of the locking element 74. Preferably, the locking grooves 82 are also arranged radially outwardly and spaced along the circumference of the recess 81 each at an angle of 120 ° symmetrically to each other.

The locking lugs 75 are engageable in a blocking state 84 in engagement with the locking grooves 82. The locking lugs 75 are arranged in alignment with the locking grooves 82. In the blocking state 84, the holding device 46 is in the driving position 50 or the trans- port position 52 arranged. In the blocking state 84, a rotational movement of the holding device 46 about the axis 68 is blocked.

The locking lugs 75 are also in a release state 86 out of engagement with the

Locking grooves 82 can be brought. In the release state 86, a rotational movement of the holding device 46 around the axis 68 is released so that the holding device 46 can be moved between the drive position 50 and the transport position 52.

In other words, the blocking element 74 is in the blocking state 84, in which the

Locking lugs 75 are in engagement with the locking grooves 82, brought by a movement in the axial direction away from the front suspension 16 when the locking lugs 75 and the locking grooves 82 are arranged in alignment. The locking member 74 is also in the release state 86, in which the locking lugs 75 are out of engagement with the locking grooves 82, brought by a movement in the axial direction in the direction of the front suspension 16.

The spring element 72 is arranged between the blocking element 74 and the receiving element 70. The spring element 72 generates a biasing force against the blocking element 74, which is directed by the receiving element 70 to the cover 76. The spring element 72 thus biases the locking element 74 in the engagement direction, so that when the locking lugs 75 and locking grooves 82 are arranged in alignment, the spring element 72 by means of the biasing force, the locking lugs 75 engages with the locking grooves 82 and thus the locking element 74 in the locked state 84 pretensions.

The actuator 80 is remote from one of the front suspension 16

Side of the cover 76 is arranged. The actuating element 80 has, on a side facing the cover element 76, three extensions 83, which are arranged radially outward around a circumference of the actuating element 80 and extend in the direction of the cover element 76. Preferably, the extensions 83 along the circumference of the actuating element 80 are each spaced at an angle of 120 ° symmetrically to each other. The cover member 76 has three complementary to the extensions 83 formed openings 77 through which the extensions 83 extend. The operation Transmission member 80 is guided in the openings 77 so that it is movable only in the axial direction 69. The extensions 83 are each hook-shaped at the end facing the front suspension 16. The front wheel suspension 16 facing the end of each extension 83 is located on a side facing away from the front suspension 16 of the locking element 74 at.

The actuator 80 may be actuated by a user of the scooter 10.

For this purpose, the user can press the actuating element 80 in the axial direction 69 in the direction of the front suspension 16. In other words, by operating the operating member 80, the operating member 80 is moved in the axial direction 69 toward the front suspension 16. As a result, the blocking element 74 is also moved in the axial direction 69 in the direction of the front suspension 16 against the biasing force of the spring element 72 from the blocking state 84 into the release state 86.

In principle, several transport positions can be provided, wherein in each

Transport position the locking lugs 75 are in engagement with the locking grooves 82. For example, in the embodiment described in FIGS. 5 to 7, basically three positions of the holding device 46 with respect to the front suspension 16 are possible, each being spaced from one another by a 120 ° rotation about the axis 68 and in which the locking lugs 75 engage with the locking grooves 82 are. These positions would thus correspond to a driving position and two transport positions.

In an alternative embodiment, it may also be provided that the

Locking element 74 only two locking lugs 75 and the recess 81 has only two locking grooves 82 which are each spaced 180 ° apart. In this case, only two positions of the holding device 46 are provided, which correspond to a driving position and a transport position.

In a further alternative embodiment it can be provided that the

Locking element 74 four locking lugs 75 and the recess 81 has four locking grooves 82 which are each spaced 90 ° apart. In this case, four positions are the Holding device 46 is provided which can correspond to a driving position and three transport positions.

In a further alternative embodiment it can be provided that the

Locking element 74 N locking lugs 75 and the recess 81 has N locking grooves 82, where N is a natural number greater than one. The Sperrnassen 75 and locking grooves are each arranged symmetrically along the circumference of the locking element 74 and the recess 81. In this case, N positions of the holding device 46 are provided, which can correspond to a driving position and N-1 transport positions.

Basically, the fixing means 66, 67 and the holding means 46 may be formed so that the holding device is pivotable only between two positions, in particular the driving position and the desired transport position, even if additional positions of the holding device 46 based on the formation of the recess 81 and of the blocking element 74 would be possible in principle.
