- a children's ride or a steering system for a children's ride is characterized by the fact that the driving characteristics, the size, etc. of the ride or the steering are tailored to the size, sensory and motor skills of children.
- the driving device or the steering can be designed in such a way that the further development of these skills is further promoted.
- the children's ride can be, for example, a scooter on which a child can assume a sitting or standing position.
- kick scooters comprising an element are known, which element can be attached or articulated to the chassis via a console and can be transferred from a position as a seat element to a position as a holding element, so that the child assumes a standing or a sitting position on the kick scooter can.
- kick scooters with a handrail and a seat that can be arranged on the handrail are known (see EP2476607).
- the child can assume a standing or sitting position on such a scooter, whereby the seat on the handrail has to be attached or removed for this purpose.
- the prior art kick scooters mentioned above as examples include a single steering system.
- these kick scooters known from the prior art have a decisive disadvantage. While a standing child can presumably operate weight-shifting steering more easily, a sitting child can presumably operate turning steering more easily, although these abilities vary from child to child and no general statement can be made in this regard.
- a kick scooter can also be referred to as a kickboard or scooter.
- a skateboard with a handrail can be called a kick scooter.
- ride-on vehicles There is also the general name of ride-on vehicles for children.
- DE69320335T2 and US4133546 describe a driving device with weight-shift steering.
- the documents FR2822430, US2014224556, US883371 and CN104369817 describe a driving device with rotary steering. In these documents, the person skilled in the art receives no incentive to supplement a driving device with weight-shift steering with rotary steering (or vice versa) or to combine the steering mechanisms mentioned with one another.
- the invention disclosed here is directed in particular to children's rides, which children's rides are designed for a standing or sitting position of the child on the children's ride.
- the invention has the task of combining the advantages of a weight-shifting steering known from the prior art and the advantages of a rotary steering known from the prior art for a children's ride.
- the invention disclosed here has the particular task of combining these advantages in a single steering system.
- the term steering mentioned above refers to those structural elements of the driving device which elements the user can operate and/or set directly or indirectly and thus change the direction of travel of the driving device rolling on a surface by positioning the wheels of the driving device in a curved direction and thus changeable Determine directions of travel.
- the basic technical solution of this invention provides that a weight-shifting steering system known from the prior art and a rotary steering system known from the prior art are coupled to one another via a mechanical forced system (hereinafter referred to as a “forced steering system”).
- the coupling by means of the mechanical forced system is such that the exclusive actuation of a steering system from the group of weight-shift steering and the rotary steering is not possible with an upright coupling of the weight-shifting steering and the rotary steering by the mechanical forced steering system.
- a mechanical constraint system between two movable elements is fundamentally characterized by the fact that a movement of one movable element is made dependent on the movement of the other movable element.
- the movement of one movable element causes a movement of the other movable element.
- the movement of one movable element requires the release of this movement of the one movable element by releasing the movement of the other movable element.
- Exclusive movement of a movable element is not possible.
- the number of degrees of freedom of the other element is therefore reduced by one degree of freedom corresponding to the movement of one element.
- the mechanical constraint system can be designed to be non-detachable or detachable. With a detachable constraint system, the user can decouple the movement of the elements.
- a mechanical forced steering system that couples the weight shift steering and the rotary steering is referred to as a mechanical forced steering system within the scope of the disclosure of this invention.
- the term “forced system” is expanded to include the term “steering”, since this forced system or “forced steering system” couples the steering systems with each other.
- the forced steering system can be designed to be non-detachable or detachable.
- the user can select a steering system from weight shift steering and rotary steering by releasing the forced steering system.
- a proposed solution according to the invention can be achieved in that at least a first wheel is connected to the chassis via a weight-shifting steering system and can be adjusted in a first curve direction by actuating the weight-shifting steering system, which first wheel is rotatably mounted on a first wheel suspension element about a first wheel axle, which first wheel suspension element is rotatably mounted on the chassis about a first wheel suspension axis of rotation, which first wheel suspension axis of rotation is inclined to the vertical by a first inclination, and at least one second wheel can be adjusted in a second curve direction by means of a rotary steering, which second wheel is rotatably mounted on a second wheel suspension element about a second wheel axis, which second wheel suspension element is rotatably mounted on the chassis about a second wheel suspension pivot point, wherein a rotary steering rod via a second coupling system is coupled to the second wheel suspension element, wherein the weight transfer steering and the rotary steering are coupled via a mechanical positive steering system, which mechanical positive steering system couples the movement of the first wheel
- the first wheel suspension element of the weight transfer steering is mounted rotatably about the first wheel suspension axis of rotation.
- the possible rotational movement of the first wheel suspension element is predetermined by the first wheel suspension axis of rotation which is inclined to a vertical.
- the first wheel suspension axis of rotation can be inclined forward or backward as viewed in the direction of travel. Other inclinations are also conceivable according to the state of the art, for example to achieve certain driving dynamics (camber, spread, toe-in).
- the inclination, in particular the inclination forwards or backwards, of the first wheel suspension axis of rotation creates an unstable position of the first wheel suspension element, so that when there is a change in the moments of force acting on the first wheel suspension element (and/or possibly forces) or the moment of force (and) transmitted by the first wheel suspension element / or if necessary forces) a positioning of the first wheel suspension element is achieved.
- the first wheel suspension element can rotate around the wheel suspension axis of rotation in a plane of movement extending at right angles to the first wheel suspension axis of rotation.
- the second wheel suspension element is rotatably mounted about a second wheel suspension pivot point.
- the second form of movement of the second wheel suspension element does not necessarily have to be limited to a second plane of movement when the second wheel suspension element is articulated via a second wheel suspension pivot point.
- a point-shaped articulation of the second wheel suspension element can be produced, for example, via a ball joint; The person skilled in the art knows other forms of point-shaped articulation.
- the first wheel suspension element and/or the second wheel suspension element can be made from a single part or from several parts, which part or parts can have elastic or rigid properties. This feature of the formation of one part or of several parts with rigid or elastic properties of the material is fundamentally applicable to all elements of the driving device mentioned in the context of the disclosure of the invention.
- a rotary steering system is characterized in that a rotary steering rod is rotated about an axis of rotation and the wheel is thus adjusted.
- the rotary steering rod can be used around its longitudinal axis Rotary axis can be rotated. Transmitting the rotational movement of the rotary steering rod as an adjusting movement for positioning the wheels requires a steering mechanism, which steering mechanism is known to those skilled in the art based on the prior art.
- the rotary steering rod and/or the rotation axis can be formed from a single element or from several elements. This can also be achieved by providing one or more joints or deformable elements between the axle sub-areas and/or rotary steering rod sub-areas.
- the elements of the rotary steering rod can be guided and positioned telescopically towards one another.
- the elements of the rotary steering rod can be coupled via gears, shafts such as and not limited to cardan shafts or deformable elements.
- the rotational movement of the rotary steering rod causes a movement of the wheel suspension element about the wheel suspension pivot point, so that the wheel articulated on the wheel suspension element is positioned.
- the second coupling system couples a movement of the wheel suspension element that can be adjusted by means of the rotary steering and a rotary movement of the rotary steering rod.
- this coupling is achieved, for example, via a steering gear or by engaging the rotary steering rod and the wheel suspension element, whereby the person skilled in the art can also provide intermediate elements such as a tie rod designed as a single element or in several parts.
- the second coupling system can be designed in such a way that positioning a wheel that can be adjusted via the rotary steering causes a movement of the elements of the rotary steering and vice versa.
- the second coupling system can further be designed in such a way that positioning a wheel that can be adjusted via the rotary steering does not cause any movement of the elements of the rotary steering, but in the opposite sense, actuation of the rotary steering causes the wheel that can be adjusted via the rotary steering to move.
- the second coupling system can be designed such that a movement of the first wheel suspension element causes a movement of the rotary steering rod. The user can thus allow or prevent the first wheel suspension element of the weight-shift steering from being adjusted using the rotary steering rod.
- the mechanical forced steering system may include at least one element, such as a rigid or deformable element, which element is articulated on the first wheel suspension element and on the second wheel suspension element.
- the element can be formed from a single part or from several parts.
- the element designed as a single part or the several parts of the element can have rigid or elastic properties.
- the element may comprise a wheel or a gear or a rod element.
- the rod element can have a straight extension axis or a single or multiple curved rod extension axis.
- the element can be articulated to one of the wheel suspension elements by arranging further elements, which further elements are arranged between the element and a wheel suspension element.
- the element can be arranged or deflected on the first wheel suspension element at a distance from the first wheel suspension rotation axis and on the second wheel suspension element at a distance from the second wheel suspension pivot point.
- This arrangement has the technical effect that a movement of the first wheel suspension element causes a movement of the second wheel suspension element.
- Those skilled in the art can also arrange the element at other points of the weight transfer steering and the rotary steering (such as on a second tie rod, a second coupling element or on the rotary steering rod) to achieve a similar effect.
- the wheels can be positioned in the cornering directions in such a way that the wheels are positioned in the same positioning directions or in different positioning directions, as can be seen in the figures below.
- the geometric rays passing through the wheel axles of the wheels intersect into a single instantaneous pole when the wheels are positioned in a single curve direction.
- the geometric rays of the wheel axles of the non-adjustable wheels and/or the adjustable wheels can also extend through this instantaneous pole.
- Positioning at least one wheel can require that a spring is pretensioned, which spring can be articulated on the one hand to an immovable element and on the other hand to a movable element.
- a spring can further or alternatively be articulated to two elements that move relative to one another.
- the spring can thus be arranged on a selection of chassis, wheel suspension element(s), tie rod(s) and/or forced steering system, taking into account the above conditions.
- the proposed solution explained above provides, among other things, that the first wheel is set by the weight-shift steering and the second wheel by the rotary steering, with the positioning process of the wheels or steering process of the steering systems being forcibly coupled.
- the weight shift steering and rotary steering coupled via a mechanical forced system provide a single wheel or two wheels (left wheel, right wheel of the driving device).
- a further solution according to the invention can be characterized in that the wheels are connected to the chassis via a weight-shifting steering system and can be adjusted in a curved direction by actuating the weight-shifting steering system, the wheels being rotatably mounted on at least one wheel suspension element about a wheel axle, which wheel suspension element is rotatable by at least a wheel suspension rotation axis is rotatably mounted on the chassis, which wheel suspension rotation axis is inclined to the vertical by an inclination, and the wheels can be adjusted in the cornering direction by means of a rotary steering, a rotary steering rod being coupled to the wheel suspension element via a coupling system, the weight transfer steering and the rotary steering via a mechanical forced steering system is coupled, which mechanical forced steering system is formed by a one-piece design of the at least one wheel suspension element, so that the wheel, which can be adjusted with the weight shift steering and/or the rotary steering, can be positioned in the same curve directions.
- the second proposed solution can also refer to just one wheel.
- the second solution variant provides that the wheels are placed using weight-shift steering and rotary steering.
- the wheels can include, for example, a left wheel and a right wheel.
- the second solution variant only one wheel is placed over the weight shift steering and the rotary steering.
- another wheel cannot be adjusted by steering.
- the additional wheel can be arranged on the driving device in a non-adjustable manner or as a freely rotatable wheel on the driving device.
- the coupling of the rotary steering and the weight-shifting steering can also have a learning effect for children or small children. Children, especially small children, are often unable to steer a driving device such as a kickboard solely using weight-shift steering. Children often find it easier to steer a ride-on toy using rotary steering.
- the mechanical coupling of rotary steering and weight-shift steering has the effect that when the rotary steering is set, the driving device according to the invention, in particular the running board of the driving device according to the invention, is transferred to a tilting position, which tilting position would correspond to the tilting position that is usual when the weight-shifting steering is actuated.
- actuation of the rotary steering also requires the scooter to be moved into the tilting position mentioned. This teaches the child how to use weight-shifting steering.
- the children's ride device according to the invention can be characterized in that a second wheel suspension rotation axis extending through the second wheel suspension pivot point extends vertically.
- the term used for vertical extension is to be understood as meaning that the axis or straight line in question extends in a vertical position when the driving device is standing on a horizontal surface.
- the axis extends parallel to the direction of the weight forces to be dissipated in a stationary driving device.
- This concept of verticality is common in children's rides such as kick scooters.
- a definition of the vertically extending axes or straight lines relative to another element of the scooter is not possible since these elements, such as a footboard of a scooter, can have any position.
- the vertical position mentioned is essential in relation to the driving characteristics of the driving device, which driving characteristics are essentially determined by the position of the ground.
- the second wheel suspension axle can be arranged vertically and thus at an angle of 90 degrees to the tread surface.
- the second movement of the second wheel suspension element is limited to a second plane of movement, which second plane of movement is oriented at right angles to the second wheel suspension axis of rotation.
- the mechanical forced steering system can be in the form of a wheel or a gear or a coupling element articulated on both elements simplest form.
- the mechanical forced steering system must, if necessary, compensate for the movement of the two elements in their different planes of movement.
- the children's ride device can be characterized in that the second wheel suspension rotation axis extending through the second wheel suspension pivot point extends at a second inclination to the vertical.
- the second wheel suspension axis of rotation may extend parallel to the first wheel suspension axis of rotation.
- a mechanical forced steering system does not have to compensate for different forms of movement of the elements moving in different planes of movement.
- the person skilled in the art can also provide a second wheel suspension axis of rotation, which second wheel suspension axis of rotation is point-shaped and thus adjustable on the chassis.
- Such a point-shaped articulation can be produced, for example, using a ball joint according to the prior art;
- the person skilled in the art knows other forms of point-shaped articulation.
- the children's ride device according to the invention can be characterized in that the wheel suspension element is rotatably mounted about a wheel suspension tilt axis.
- Tilt steering systems are known from the prior art, which tilt steering systems allow a rotating movement of a wheel suspension element about a tilt axis oriented essentially parallel to the direction of travel (when driving straight ahead) or to the central axis of the driving device.
- the children's ride device according to the invention can be characterized in that the weight-shifting steering comprises a force introduction element.
- the force introduction element transmits forces acting directly or indirectly on the force introduction element into the weight-shifting steering system, so that a changed force state caused by the forces causes an actuation of the weight-shifting steering system.
- the force introduction element can be formed by the chassis or by the holding rod.
- the user can stay on the chassis like on a tread and bring about a changed state of force by changing his position.
- the user can also remain on an element connected to the chassis or to the support rod and cause a changed state of force by changing the position.
- a seat connected to the support rod is known, on which seat the person can make a position change to actuate the weight shift steering.
- the user can hold on to the handrail.
- the rotary steering rod can be designed as a holding rod and thus act as a force introduction element.
- the children's ride device can be characterized in that the rotary steering comprises a rotary steering rod and optionally a handlebar, the mechanical forced steering system coupling the movement of the single rotary steering rod and the movement of the wheel suspension elements.
- the rotary steering can comprise a single rotary steering rod.
- the user grips the handlebars with his hands. The user can thereby allow or prevent adjustment of the first wheel suspension element and the second wheel suspension element.
- the second wheel suspension element is coupled to the rotary steering rod via a mechanical forced steering system.
- a mechanical forced steering system couples the positions of the wheel suspension elements.
- the children's ride device comprising at least two first wheels, each first wheel being rotatably mounted about a wheel suspension pivot point via a wheel suspension element, can be characterized in that the first wheel suspension elements and the second wheel suspension elements are formed in one piece, with a rotating steering rod being connected to each wheel suspension element, whereby the forced steering system couples the movements of the rotating steering rods.
- a one-piece design of the wheel suspension elements requires a one-piece design of the wheel suspension axles. Since the first wheel suspension axles are inclined to a vertical by definition, this embodiment requires that the second wheel suspension axle is also inclined.
- a rotating steering rod can be rotated by the user about its longitudinal axis and thus cause movement of the second wheel suspension element. Such a movement of rotary steering rods is common in children's rides such as kick scooters or scooters which have rotary steering.
- the rotary steering rod can further be rotated about another point or about an axis by the user to cause actuation of the rotary steering.
- the rotary steering rod can be mounted rotatably about a wheel suspension axis of rotation to actuate the rotary steering.
- the mechanical forced steering system can be formed by an element which is connected to the rotary steering rods.
- the element can form a handle.
- the element can be rigidly connected to the rotating steering rods.
- the children's ride device according to the invention can be characterized in that the first wheel and the second wheel are formed in one piece.

- one wheel suspension element is to be viewed as the first wheel suspension element and as the second wheel suspension element; the first wheel suspension element and the second wheel suspension element are formed in one piece.
- One wheel is connected to the one wheel suspension element via a wheel axle.
- the one-piece design of the first wheel and the second wheel as one wheel is in no way limited to a one-piece design of the wheel suspension elements.
- One wheel can also be connected to the first wheel suspension element and to the second wheel suspension element.
- the weight shift steering and the rotary steering cause one wheel to move.
- the children's ride device can be characterized by a one-piece design of the first wheel and the second wheel in that the mechanical forced steering system is designed as a one-piece wheel suspension elements.
- the mechanical forced steering system can also be formed by further integrally formed elements of the weight shift steering and the rotary steering such as tie rods, wheel suspension rotation axes, etc.
- the person skilled in the art can combine the one-piece design of several elements of the rotary steering and the weight-shifting steering.
- the children's ride device according to the invention can be characterized in that the first wheel and the second wheel are different wheels.
- the first wheel is therefore placed via the weight-shifting steering and the second wheel is placed via the rotary steering, the weight-shifting steering and the rotary steering being coupled via a mechanical forced steering system. Setting the first wheel always requires setting the second wheel and vice versa.
- Children's ride device comprising two first wheels and at least one second wheel, the first wheels being adjustable via a weight-shifting steering system and the at least one second wheel being adjustable via a rotary steering system, and the weight-shifting steering system being coupled to the rotary steering system via a mechanical forced steering system.
