Abstract

A scooter, which is driven by an electric motor, for transporting persons, includes an electric drive motor and a standing platform. A front wheel is arranged along a center axis of the standing platform. A steering rod is coupled to the front wheel. Handlebars pivot the front wheel about a rotational axis, which is formed by the steering rod. Two rear wheels are at a spacing from the front wheel and are each arranged laterally offset with respect to the center axis. A feed-through aperture, which is preferably completely closed circumferentially and is passed through by the steering rod, or in which the front wheel sits, is incorporated into the standing platform. The front wheel is flanked on both sides in each case by at least one support element which projects from an underside of the standing platform that faces an underlying surface.

First claim

What is claimed is:

1. A scooter for transporting persons, comprising:
an electric drive motor;
a standing platform;
a front wheel which is arranged along a center axis of the standing platform;
a steering rod coupled to the front wheel at a first end of the steering rod;
handlebars for pivoting the front wheel about a rotational axis which is formed by the steering rod, wherein the handlebars are connected to the steering rod at second end of the steering rod and wherein the second end is located opposite the first end and the front wheel; and
two rear wheels which are at a spacing from the front wheel and are each arranged laterally offset with respect to the center axis, wherein
the standing platform is a flat surface, a region of a rear edge of an upper side of the flat surface has a foot mat, and the two rear wheels project from an underside of the flat surface that faces an underlying surface,
a feed-through aperture, which is completely closed circumferentially and is passed through by the steering rod, or in which the front wheel sits, is incorporated into the standing platform as a recess defined by the standing platform, and
at least one support element arranged on each side of the front wheel projects from the underside of the standing platform that faces the underlying surface.

2. The scooter as claimed in claim 1 , wherein
the support elements are positioned on the underside in each case laterally outside a tilt line which extends between the front wheel and a respective rear wheel.

3. The scooter as claimed in claim 2 , wherein
the support elements are support wheels.

4. The scooter as claimed in claim 1 , wherein
the support elements are arranged behind the front wheel, offset toward the rear wheels along the center axis.

5. The scooter as claimed in claim 1 , wherein
the front wheel is driven by the electric drive motor.

6. The scooter as claimed in claim 5 , wherein
the electric drive motor is a wheel hub motor of the front wheel.

7. A scooter for transporting persons, comprising:
an electric drive motor;
a standing platform;
a front wheel which is arranged along a center axis of the standing platform;
a steering rod coupled to the front wheel;
handlebars for pivoting the front wheel about a rotational axis which is formed by the steering rod; and
two rear wheels which are at a spacing from the front wheel and are each arranged laterally offset with respect to the center axis, wherein
a feed-through aperture, which is completely closed circumferentially and is passed through by the steering rod, or in which the front wheel sits, is incorporated into the standing platform,
at least one support element arranged on each side of the front wheel projects from an underside of the standing platform that faces an underlying surface, and
the front wheel, which is arranged within the feed-through aperture, is pivotable about 360° by way of the handlebars.

8. A scooter for transporting persons, comprising:
an electric drive motor;
a standing platform;
a front wheel which is arranged along a center axis of the standing platform;
a steering rod coupled to the front wheel;
handlebars for pivoting the front wheel about a rotational axis which is formed by the steering rod;
two rear wheels which are at a spacing from the front wheel and are each arranged laterally offset with respect to the center axis, wherein
a feed-through aperture, which is completely closed circumferentially and is passed through by the steering rod, or in which the front wheel sits, is incorporated into the standing platform, and
at least one support element arranged on each side of the front wheel projects from an underside of the standing platform that faces an underlying surface; and
a vehicle battery integrated in the steering rod for power supply of the electric drive motor.

9. The scooter as claimed in claim 1 , wherein
the steering rod is pivotable in relation to the standing platform.
