Description

The present disclosure relates generally to a kick scooter, and more particularly to an electrified kick scooter (e-scooter).

Kick scooters are well known. Ordinary scooters are operated with muscle power. Newer scooters have an integrated electric drive (e-scooter).

Ordinary scooters are muscle-powered, two-wheeled small vehicles with a step close to the ground on which a person (driver) can move while standing. Kick scooters are driven by the driver by pushing one of his legs and can be made of wood, plastic-reinforced plastics and / or metal.

Two-wheeled scooters are single-track and have rim sizes of up to 28 inches. Usually, scooters have pneumatic tires. The larger the wheels, the higher the speeds that are possible in principle.

In the middle of the 2010s, the first, compact battery electric scooters (e-scooters) came onto the market, which became popular worldwide with the launch of commercial rental systems from 2018 and which subsequently increased sales of scooters for adults. The electrification of scooters, i.e. the use of integrated electric drives, has led to e-scooters being operated at a higher average speed. Due to their range, e-scooters have also led to an increase in general short-distance mobility (5 to 15 km).

So-called kickboards are also known. Kickboards are also muscle-powered and - unlike classic scooters - have three rollers or wheels (and are therefore two or three lanes) and the handlebar is a round knob, similar to a gear lever in a car. Kickboards are a combination of a skateboard and a scooter. You steer by tilting the knob to the side and shifting your weight.

When driving long distances, the use of scooters can be tiring for the driver because the driver has to stand on the step all the time. This applies regardless of whether the scooter is powered by muscle power or electrically. That is why there are already scooters that are equipped with a seat and / or saddle where the rider can sit down (anatomically with his buttocks). In the 5 Muscle-powered and electrified scooters with seating are shown as examples.

Scooters that are equipped with a seat or saddle, however, make the rider's overview worse because the rider sits lower than he is standing. Dangers are recognized later when sitting than when standing.

With conventional scooters without a seat, the driver holds on to the handles on the handlebars with both hands while the driver stands on the step. Signaling a turning maneuver by hand is almost impossible because the driver has to take one of his hands off the handlebars for this purpose in order to stretch out the associated arm to the side. In this case, the driver only holds on to the handlebars with one hand. This deteriorates the stability. The driver feels insecure. The risk of the driver falling increases. The slower the scooter is moved and the smaller the diameter of the wheels, the greater the uncertainty. The wheelbase also plays a role. Increased stability would be desirable, especially during turning maneuvers that are signaled by hand signals.

It is therefore an object of the present disclosure to provide an improved, in particular electrified, scooter.

This object is achieved by a scooter with: a step which is oriented essentially parallel to a driving surface during use and which defines a standing surface for a driver; a first wheel, which is mounted in the direction of travel on a front portion of the footboard, and a second wheel, which is mounted on a rear portion of the footboard; a handlebar with handlebar, wherein the handlebar is oriented substantially perpendicular to the driving surface and is mounted on the front portion of the footboard; preferably an electric drive and an energy store; and a (multifunctional) leaning device which comprises a leaning rod which is oriented essentially perpendicular to the driving surface, the leaning device being set up so that the driver can lean against the direction of travel, in particular in the area of an upper iliac crest of the driver, during the Driver drives standing on the step.

The fact that the driver can lean against it while driving means less driver fatigue.

At the same time, however, the driver has a good view of the traffic situation, as his vision is better when standing than when sitting. The eyes are positioned higher than when sitting. This enables the driver to recognize dangerous situations at an early stage.

The driving experience is also improved. By leaning against and holding the handlebars at the same time, the rider can build up a higher body tension in order to keep the scooter more stable. This applies in particular to cornering and turning maneuvers that are signaled by hand signals.

Another advantage is that turning maneuvers can be signaled by hand because the driver has an (additional) contact point between his body and the scooter in axial alignment with the footboard. With conventional scooters, the driver can only hold on with one hand, which is then arranged off-axis and thus leads to instability (the line between the hand on the handlebar and the foot on the footboard is off-axis).

The leaning device is preferably free of a seat and / or saddle.

In this way, it is prevented that the driver's point of view is lowered compared to standing.

In particular, the scooter is single-track.

This means that a front wheel and a rear wheel drive in the same lane when driving straight ahead. In this sense, a kickboard is a three-lane vehicle. The leaning device is therefore particularly aimed at single-lane vehicles, because there the stability is increased by the driver leaning against it.

It is also advantageous that the height of the leaning bar is adjustable.

In this way it is possible to set a leaning point (preferably in the area of the upper iliac crest) depending on the size of the driver. Big drivers and small drivers alike can lean comfortably and safely.

The leaning bar is preferably designed in several parts, the parts of the leaning bar being mounted in particular so as to be displaceable relative to one another.

In a further special embodiment, the leaning device has a leaning member which is shaped such that the driver, when leaning against it, is received almost positively in the area of his upper iliac crest.

It is also advantageous if the region of the leaning member facing the driver is designed in the shape of a bowl.

The bowl shape enables the driver's pelvis to be positively received when the driver leans against it. The width can be varied in the horizontal direction.

In particular, the leaning member is arranged in an upper (vertical) end section of the leaning rod.

It is also advantageous if an area of the leaning member facing away from the driver has a, preferably spherical, protrusion which can be set up as a pushing and lifting aid and as a load suspension (e.g. for luggage).

The driver can, for example, hang a bag on the spherical projection without impairing the stability of a straight-ahead journey.

When climbing stairs, the driver can grab the scooter by the spherical protrusion and lift it.

When going uphill, the rider can grab the scooter by the spherical protrusion and push it up the mountain.

Preferably, the leaning bar forms an angle of 10-20 degrees with the vertical one.

It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the respectively specified combination, but also in other combinations or on their own, without departing from the scope of the present invention.

An embodiment of the invention is shown in the drawings and is explained in more detail in the following description. Show it:

• 1 a block diagram of a scooter;
• 2 a schematic side view of a scooter with leaning device;
• 3 a side view of another scooter;

1 Figure 3 shows a block diagram of a scooter 10 .

The scooter 10 generally has a running board 12th , at least two wheels 14th and a (vertical) handlebar 16 with a (horizontal) handlebar 18th on. The following can optionally be provided: an electric drive 20th as well as a corresponding energy storage (battery) 22nd who have both in the scooter 10 can be integrated.

The scooter 10 further comprises a leaning device 24 and optionally a brake 26th .

The scooter 10 is single-track. This means that there are at least two wheels 14th move in the same lane when driving straight ahead.

2 shows a schematic view of an embodiment of the scooter 10 on which a driver 28 and the example from right to left (direction of travel 30th ) moves.

The step 12th can be designed in one or more parts. In the 2 is the stepping stone 12th eg formed in two parts and comprises a front section 32 which can be slightly inclined towards the ground, as well as a rear section 34 , which is preferably oriented parallel to the ground. The driver 28 stands on a stand 36 of the running board 12th that extends over the entire footboard 12th or only parts of it can extend.

The front wheel 14-1 is on the front portion 32 appropriate. The rear wheel 14-2 is on the rear portion 34 appropriate.

The handlebar 16 is also on the front section 32 attached and closes in the 2 an exemplary angle of 10 degrees with the vertical that is perpendicular to a driving surface 38 (Underground) stands. The driving surface 38 is in the 2 horizontally aligned as an example. It goes without saying that the scooter 10 but can also be used for uphill or downhill driving. The stand area 36 is preferably parallel to the driving surface 38 oriented.

The handlebar 16 is preferably to the driver 28 inclined towards. The angle of inclination of 10 degrees is only exemplary. Tilt angles of 10 to 20 degrees are common. The handlebar 16 is in this sense “essentially perpendicular” to the driving surface 38 oriented.

The driver 18th Includes a bar and optional handles (unspecified) to keep the driver comfortable 28 can hold on to with both hands while driving. The rod is perpendicular to the plane of the drawing 2 oriented.

The leaning device 24 includes a one-piece or multi-piece leaning bar 40 . In the 2 is a two-part leaning bar 40 shown, the height-adjustable (compare double arrow 42 ) can be formed. It goes without saying that the leaning bar 40 can consist of more or fewer parts.

The leaning device 24 is - like the handlebar 16 - "essentially perpendicular" to the driving surface 38 oriented. This means that the leaning bar 40 does not have to enclose an angle of exactly 90 ° with the subsurface. Slight angular deviations are permitted. Specifically, in the 2 an angle of inclination of approximately 15 degrees is shown. The angle of inclination can be changed.

Furthermore, the leaning device comprises 24 a leaning link 44 , which is arranged at the upper end of the leaning rod part 40 '.

The leaning link 44 serves to keep the driver 28 on the scooter 10 can lean on it while standing. The arrow 46 illustrates a leaning direction that is opposite to the direction of travel 30th is oriented and which is essentially free of vertical components (seating). In other words, this means that the driver is 28 in the direction of travel backwards on the leaning device 24 leans against it while driving standing. The driver 28 does not sit on the leaning link 44 but leans in the direction 46 only on the scooter 10 away.

The (relative) height of the corresponding contact point is preferably selected so that the driver is 28 in the area of his upper iliac crest (anatomy) leans, this area in the 2 with a dashed line 48 is outlined. The sitting-free leaning in the area of the upper iliac crest is particularly good from the side view of the 3 can be seen showing another embodiment of a scooter 10 indicates.

For this purpose, the leaning link 44 in its front area 50 preferably bowl-shaped around the driver's pelvis 28 form fit as it looks good 4th can be seen, which is yet another embodiment of a scooter 10 indicates..

In the 2 can in the rear area 52 that from the driver 28 is turned away, the leaning link 44 a, preferably spherical, projection 54 (e.g. a knob), which serves multifunctionally as a pushing aid, lifting aid and / or load suspension. At the lead 54 can the driver 28 e.g. a bag, a (shopping) basket 55 Make purchases or the like while using the scooter 10 moves. The basket 55 could also be placed elsewhere (see e.g. 4th ).

It goes without saying that the driver 28 so has a good overview while he drives, relaxed, standing. Even when signaling a turning maneuver by hand, stability is guaranteed due to the additional contact point with the support.
