The plate may also comprise hinges, as described below. [Background technology] 【0005】 Canadian Patent 2762892 discloses a vehicle with a second side having wheels for rolling on the ground, however, the vehicle does not include a plate having such a second side and a first side for sliding or rocking on the ground. 【0006】 WO2020053855 discloses a vehicle, but the vehicle does not have wheels and sliding surfaces for alternative use. 【0007】 In the prior art, a vehicle with the product name wheelybug is known. The plate of the vehicle has a first side with a sliding surface and a second side with a wheel, as described on the website Not disclosed in JPEG2025515649000002.jpg846. 【0008】 The vehicle disclosed on the website shop.chillafish.com does not have a first side with a sliding surface and a second, opposite side with wheels. An element designed to sit on the vehicle cannot be releasably placed on a plate with these sides. The sliding surface is not formed in a planar shape. A small child can use the vehicle for rocking (U.S. Design Patent No. 878,480). 【0009】 The vehicles disclosed in each of U.S. Patent No. 6,676,148, China Patent Publication No. 104973184, International Publication No. 2021040620, U.S. Patent No. 5,441,289, U.S. Patent No. 10,470,585, Taiwan Patent Publication No. 201707758, Spain Utility Model No. 1009546, Japan Utility Model No. 0528392, and China Utility Model No. 206950648 do not include a plate having a first side with a substantially planar sliding surface and a second side with rollers for alternative use. 【0010】 CN Utility Model No. 212395837 comprises a plate with a wheel disposed on a second side, but the plate does not include a sliding surface opposite the second side. The side of the plate from CN Utility Model No. 212395837 does not include a resting surface. The plate comprises a recess for receiving an inflatable element. 【0011】 The vehicle disclosed in U.S. Patent Application Publication No. 2002164917 does not include a plate having a sliding surface disposed on a first side and a wheel disposed at a second location opposite the first side. 【0012】 The difference between the invention described below and ITPD20090281 becomes clear based on the cross-sectional view in, for example, Fig. 6 of ITPD20090281. Reference number 12 denotes an operating means, which means that said means is necessarily required to use the device disclosed in ITPD20090281. The presence of the operating means prevents the surface located at the top of Fig. 6 from being used as a sliding surface. 【0013】 U.S. Design Patent No. 878,480 discloses a vehicle having a curved sliding surface on only a first side. The vehicle does not have wheels on a second side. 【0014】 US Patent No. 2,595,839 shows a vehicle with a sliding part. The vehicle has wheels on one side, but the other side cannot be used as a sliding surface due to a protuberance. The sliding part includes a flat surface on one side, but the other side is not formed as a single curved surface. 【0015】 DE 297 22 538 discloses a vehicle having wheels but no sliding surfaces. 【0016】 Online Link JPEG2025515649000003.jpg6158 reveals another vehicle with a sliding surface on a first side and at least one wheel on a second side. The sides each have a resting surface. The vehicle shown by this link does not have a receptacle for placing a seating / holding element on either the first or second side. 【0017】 FIG. 6 of US2019193770 shows a vehicle having a first side implemented as a sliding surface and a side provided with at least one wheel, the vehicle further comprising a rope as a retaining element 224, 229, 225, 227. FIG. 6 of US2019193770 shows that the vehicle disclosed in D1 comprises a retaining element as a string. US2019193770 does not show that the retaining element is releasably arranged on the plate. The rope is a flexible element. Thus, US2019193770 does not disclose that the retaining element is formed from a solid material, or an expandable or expansive material. A solid material is understood to mean a material that can be arranged in a special layer and that maintains said assigned layer. US2019193770 does not disclose that the handle can be arranged in a longitudinal position by being inserted into a receiving device. Moreover, this is not possible due to the flexibility of the rope. For example, from FIG. 6 of US2019193770, it can be seen that the hole for receiving the rope extends horizontally as a handle. Thus, even the sub-area of ​​the rope extending into the hole is not arranged vertically as a handle.

[Means for solving the problem] 【0020】 According to the invention, this is achieved by the independent claims. 【0021】 The vehicle of the present invention comprises: the first side includes at least one first sliding surface having a first sliding characteristic for sliding the surface on a ground surface; the first sliding surface is formed as a planar sliding surface extending over a sub-region of the first side surface or over the entire first side surface, the second side includes at least one wheel for displacing the vehicle in a direction of travel over a ground surface; the first side comprises a first retention surface and / or the second side comprises a second retention surface; the first side and / or the second side are provided with a first receiving device and a second receiving device, respectively, for releasably arranging a seating / retaining element; The seating / holding element may be formed as an element, which may be converted from a first position for use as a seating element to a second position for use as a holding element, or the seating / holding element may be formed only as a seating element, or the seating / holding element may be formed only as a holding element, the seating / retaining element is made from a solid material or from an expansive or expandable element, It may be characterised in that the receiving device is formed to position the seating / holding element in a horizontal or vertical position relative to the plate. 【0022】 The first sliding surface may be a single sliding surface. The first sliding surface may also be formed as a plurality of first sliding surfaces. The plurality of first sliding surfaces may be spaced apart from each other and thus implemented separately. The plurality of first sliding surfaces may also be formed adjacent to each other. 【0023】 In its contact area with the ground, the sliding surface comprises a planar and / or smooth surface in both directions of extension of the surface for contacting the ground. The sliding surface may be formed as a sliding surface on the surface adjacent to the contact area with the ground. 【0024】 In its contact area with the ground and optionally in the surface adjacent or adjacent to said contact area, the longitudinal extension of the sliding surface may be oriented substantially parallel to the direction of movement of the vehicle of the invention and parallel to the direction of relative movement between the sliding surface and the ground. A planar sliding surface extends parallel to the special shape of the planar ground. 【0025】 In an advantageous manner, the sliding surface does not comprise part surfaces extending transversely to the direction of movement. In this advantageous embodiment, the sliding surface only comprises part surfaces extending longitudinally substantially parallel to the direction of movement. The part surfaces referred to in this specification do not necessarily have to appear as such. 【0026】 The sliding surface may be formed as a geometric surface having no curvature in the contact area with the ground and optionally in the surfaces adjacent or adjacent to the contact area and thus being planar. 【0027】 Planar sliding surfaces are used in a conventional manner and have the technical effect that when moving over a planar ground surface, the sliding surface contacts the ground over its entire surface, preventing rocking or relative movements that would change the extent of the contact surface between the sliding surface and the ground. Planar sliding surfaces can include planar sub-areas at different heights. The planes may have a cascading design. 【0028】 In addition to or instead of the planar formation of the sliding surface described above, the sliding surface may be curved one or more times. 【0029】 The curved sliding surface may be curved only about a first axis, the first axis being oriented at a 90° angle to the direction of movement. Curvature about multiple axes is also possible. 【0030】 The sliding surface may be characterized by a coefficient of friction less than 0.5. 【0031】 The second side may include a single wheel. The second side may also include multiple wheels. A person skilled in the art will select the number of wheels depending on the desired rolling characteristics of the vehicle. 【0032】 The first receiving device on the first side and the second receiving device on the second side are described in the present disclosure below. 【0033】 The seating / retaining element may be formed as an element that can be transformed from a first position for use as a seating element to a second position for use as a retaining element. The seating / retaining element may be formed only as a seating element. The seating / retaining element may be formed only as a retaining element. This definition is applicable throughout the entire disclosure of the present invention. 【0034】 When used as a seating element or as a holding element or as an element which can be converted from a seating element to a holding element and vice versa, the seating / holding element may be formed as a rigid element. 【0035】 In its use as a seating element, the seating / holding element extends substantially horizontally. In its use as a holding element, the seating / holding element extends substantially vertically. A rigid element may be defined such that if the element is used as intended and under a common load, then only to the extent that the use of the rigid element for this purpose is possible. 【0036】 The seating / retaining element may therefore be formed as a rigid element. The seating / retaining element as a retaining element may also be implemented to be non-flexible, in particular as a retaining rod. The sufficiently rigid properties mean that it is made of a solid material. 【0037】 The seating / retention element may be made from an expandable portion of the expandable element. 【0038】 The plate and / or the seating / holding element may be made of a plastic or foam material such as EPP. The use of a foam material is particularly advantageous in that it may allow children to lift the vehicle of the invention. Furthermore, the lower weight allows children to push the vehicle of the invention in a sliding or rolling manner. 【0039】 The vehicle of the invention may be formed such that it moves in the direction of movement envisaged for its conception. Said direction of movement may be determined by the shape of the wheels. The direction of movement may be defined by the shape of the sliding surface, which, like the sliding boards of a sled or ski, for example, has its greatest extension parallel to the envisaged direction of movement when running normally and straight ahead. 【0040】 The above solutions comprise a seating / retaining element which is releasably attached to one side of the plate via a receiving device. 【0041】 The vehicle of the present invention comprises: the first side includes at least one first sliding surface having a first sliding characteristic for sliding the surface over a ground surface; the first sliding surface is formed as a planar sliding surface extending across a sub-region of the first side surface or across the entire first side surface, or a first sliding surface extending across the first side and formed as a single surface curved about a first axis; a first axis extends in a first plane spaced apart from the ground at an angle of 90° to the direction of movement; the second side includes at least one wheel for displacing the vehicle in a direction of travel over a ground surface; the first side comprises a first retention surface and / or the second side comprises a second retention surface; a seating / retaining element formed integrally with the plate is disposed on the first side and / or the second side; The seating / holding element may be formed as an element, which may be converted from a first position for use as a seating element to a second position for use as a holding element, or the seating / holding element may be formed only as a seating element, or the seating / holding element may be formed only as a holding element, the seating / retaining element is made from a solid material or from an expansive or expandable element, The receiving device is configured to place the seating / holding element in a horizontal or vertical position relative to the plate; The present invention may be characterized in that: 【0042】 The seating / retaining element may also be implemented integrally with the plate. 【0043】 The sliding surface formed as a single surface curved about a first axis or plane may be formed as a surface having depressions or protrusions, either continuous or formed from one element or material. The depressions or protrusions may extend tangentially to the curved surface. 【0044】 The sliding surface may be curved about a single first axis. The sliding surface may be curved about only the one first axis. In the present invention, it is also possible for the sliding surface to be curved about additional axes. 【0045】 The embodiment of the vehicle of the present invention described above comprises a sliding surface on a first side and wheels on a second side for moving the vehicle of the present invention on a ground surface. This formation defines two sides of the vehicle of the present invention having different movement characteristics at a relative movement v≧0 with respect to the ground surface. 【0046】 Different movement characteristics can be achieved by providing sliding surfaces with different characteristics. 【0047】 The vehicle of the present invention comprises: the first side comprises a first sliding surface having a first sliding characteristic; the second side includes a second sliding surface having a second sliding characteristic; The first sliding surface and the second sliding surface are formed in a planar shape, The first sliding characteristic and the second sliding characteristic are different. The present invention may be characterized in that: 【0048】 The different sliding characteristics may be achieved by different geometrical formations of the sliding surfaces. Additionally or alternatively, the different sliding characteristics may be achieved by forming the sliding surfaces with different coefficients of friction with respect to the ground. 【0049】 When the first side surface is the first sliding surface, the second side surface is the second placement surface. When the second side surface is the second sliding surface, the first side surface is the first placement surface. 【0050】 The vehicle of the present invention comprises: the first side comprises a first sliding surface having a first sliding characteristic; the second side includes a second sliding surface having a second sliding characteristic; One of the sliding surfaces is formed flat, One of the sliding surfaces is formed as a curved surface, the curved sliding surface extends across the first side within a sub-region of the first side or across the entire first side, The curved sliding surface is curved about a first axis; a first axis extends in a first plane spaced apart from the ground at an angle of 90° to the direction of movement; The first side comprises a first retention surface and / or the second side comprises a second retention surface; The present invention may be characterized in that: 【0051】 The inventions disclosed herein generally provide that the vehicle of the invention can either slide on a first side or roll or slide on a second side on the ground. By rotating a plate or seating / retention element of the vehicle of the invention, the first side or the second side may be selectively oriented toward the ground. 【0052】 The infant may sit, stand, kneel, or in any other position on each of the upward facing resting surfaces. 【0053】 Since no boundaries should be set for the infant, the term "dwelling surface" is used to describe the manner in which the infant dwells on the dwelling surface. A dwelling surface is generally a surface configured such that the infant can remain on it, either by sitting or standing, or without having to modify or adapt the dwelling surface in any other way. 【0054】 The retention surface may have a reinforcing material. 【0055】 The retention surface and / or plate may be formed to be elastically and / or plastically deformable, such that a person carrying excess weight will deform the retention surface or plate such that movement of the plate is prevented. 【0056】 The restraint surface may have a rough surface to prevent a child from slipping off. 【0057】 The vehicle of the present invention comprises: the first side comprises a first sliding surface having a first sliding characteristic; the second side includes a second sliding surface having a second sliding characteristic; The sliding surface is formed as a curved surface, each curved about a first axis; a first axis extends in a first plane spaced apart from the ground at an angle of 90° to the direction of movement; The first side comprises a first retention surface and / or the second side comprises a second retention surface; The present invention may be characterized in that: 【0058】 In the two most recently mentioned embodiments, the first and second sliding characteristics may be the same or different. In particular, the first and second sliding surfaces may have equal or different coefficients of friction against the ground. 【0059】 The invention disclosed herein may be based on the use of a single plate. 【0060】 The invention disclosed herein may be based on the use of a number of plates, which are preferably connected to architectural elements that function as static plates. The connection of the elements may be implemented in such a way that an operator can release or lock the connection of the architectural elements when converting the vehicle of the invention into a storage position. The user may release or lock the connection, for example, depending on the use of a seating / holding element as described below or depending on the user's position on the vehicle. 【0061】 In its contact area with the ground, and optionally in the longitudinal extension and (relative) direction of movement, in the surfaces adjacent to or adjacent to the contact area, the planar or curved sliding surface may have a dimension that is greater transverse to the longitudinal extension or (relative) direction of movement. 【0062】 A planar or curved sliding surface may be characterized in that the surface load transferred from the sliding surface to the ground does not exceed a threshold value, so that neither the sliding surface nor the ground is deformed by common loads and typical use conditions. The surface load should be selected by dimensioning the sliding surface such that a child pushing the vehicle or a child positioned in the vehicle and accelerating can overcome the static friction acting between the sliding surface and the ground. 【0063】 A sliding surface that moves relative to the ground and is in contact with the ground may be deformed, especially at its leading edge in the direction of movement, and the leading edge may be easily caught by unevenness in the ground. The leading edge of a planar or curved sliding surface may be shorter than the longitudinal extension of the sliding surface. The planar or curved sliding surface may include a scoop shape in the region of its leading edge, which includes a curve or other surface that extends away from the ground. 【0064】 The vehicle of the present invention may comprise a plurality of planar sliding surfaces distributed on the first side of the plate and extending over sub-areas of the first side. The planar sliding surfaces may be arranged in corner areas of the first side of the plate. This is also applicable to further embodiments of the present invention comprising sliding surfaces. 【0065】 The curved sliding surface may allow the child to swing. When swinging, there is always a risk of the child getting caught between the moving sliding surface and the ground. In this connection, it should be noted that a high number of edges increases the risk of getting caught. This is why only curved sliding surfaces are provided to increase safety. 【0066】 The edge of the sliding surface may be located at a distance from the edge of the first side. A person skilled in the art will select the distance between the edge of the sliding surface and the edge of the first side to be large enough so that a child cannot place a hand or finger under the sliding surface. The vehicle of the present invention may be characterized in that the first sliding characteristic and the second sliding characteristic are different. 【0067】 The sliding properties of a surface are determined by the design of the surface and the choice of material. The choice of material for the side may define the coefficient of friction of said side against the ground. 【0068】 Thereby, a person skilled in the art may form sides with different sliding characteristics to allow a child using the vehicle of the present invention to have different sliding experiences when using different sides. This is applicable to all embodiments of the vehicle with sliding surfaces. The vehicle of the present invention may be equipped with a holding device or an element generally suitable for gripping or holding, which is arranged adjacent to or within the resting surface so that a child resting on the resting surface can hold onto the holding device. 【0069】 The above description relates inter alia to a sliding surface which is curved once, although a sliding surface which is curved twice is also possible. 【0070】 The sliding surface may have a flat surface. 【0071】 The sliding surface may have one or more concave or convex or otherwise curved surfaces. 【0072】 In general, the sliding surfaces may be made from materials that do not deform under typical loads. 【0073】 In general, the sliding surface may be made of an elastically and / or plastically deformable material. A sliding surface made of a deformable material may further allow bouncing motion of the child with the vehicle, with the flexibility and / or damping properties of the material supporting or preventing such motion. 【0074】 The sliding surface may comprise a deformable cavity, the cavity being filled with a gas at normal or excess pressure. 【0075】 The vehicle of the present invention comprises: The curved sliding surface is formed as a sliding surface curved about a second axis, The second axis extends in a second plane spaced from the ground at an angle of 90° to the direction of movement; The present invention may be characterized in that: 【0076】 The vehicle of the present invention preferably comprises a curved sliding surface about a single axis or about multiple axes on one side and a planar sliding surface or at least one wheel on the other side. The feature of at least one wheel is understood to mean that the other side includes a single wheel or multiple wheels. 【0077】 The sliding surface may, for example, be elliptical. 【0078】 The vehicle of the present invention comprises: The sliding surface is curved about a plurality of first axes and / or a plurality of second axes; The present invention may be characterized in that: 【0079】 The shape of the curved sliding surface is not limited to a circular arc in any view. The curvature may also be in the shape of a subregion of an ellipse. According to current teachings, a surface curved to approximate an ellipse has multiple axes of curvature parallel to each other, since an ellipse includes foci. 【0080】 The sliding surface may have any shape, and may be curved in one direction or in multiple directions. 【0081】 The sliding surface may include multiple arcs or curves that are spaced apart or continuous with one another. 【0082】 The sliding surface may be wavy. 【0083】 The vehicle of the present invention comprises: The first sliding characteristic is different from the second sliding characteristic; The present invention may be characterized in that: 【0084】 The characteristics of the different sliding properties are described above based on the planar potential embodiments of the first and second sliding surfaces. It is also possible for curved and planar sliding surfaces, or curved sliding surfaces, to have different sliding properties from each other. 【0085】 In the literature, the sliding properties of one surface are described in terms of the coefficient of friction against another surface. 【0086】 The vehicle of the present invention comprises: The direction of movement is oriented parallel to the longitudinal extension of the plate or sliding surface or at an angle to the longitudinal extension. The present invention may be characterized in that: 【0087】 The angles referred to are preferably acute angles, ie angles between 1° and 45°, preferably between 10° and 30°. 【0088】 However, angles of 90° or angles other than 90° are also possible. 【0089】 The vehicle of the present invention allows a child to freely choose the direction of travel. The vehicle of the present invention may not have a preferred direction of travel. 【0090】 The vehicle of the invention may comprise at least two sliding surfaces, the longitudinal extensions of which are arranged relative to one another at the mentioned angle. 【0091】 The vehicle of the invention may comprise at least two sliding surfaces, the longitudinal extension directions of which are arranged symmetrically to the direction of movement and at the mentioned angle relative to one another. 【0092】 As described above on the basis of one embodiment, the seating / retaining element may be arranged on one side of the plate via a receiving device, nevertheless, embodiments of the invention described without such a receiving device may also comprise such a receiving device. 【0093】 The vehicle of the present invention comprises: the first side and / or the second side are provided with a first receiving device and a second receiving device, respectively, for releasably arranging a seating / retaining element; The present invention may be characterized in that: 【0094】 The receiving device may be implemented as a releasable mechanical connection means for mechanically connecting the plate and the seating / retaining element. The receiving device may be scaled to prevent relative movement between the plate and the seating / retaining element under typical loads and / or movements due to the connection made. 【0095】 The receiving device may create a well-defined arrangement of seating / retention elements on and against the plate, which can be achieved by matching shapes to fit together. 【0096】 The mechanical connection may prevent separation of the plate and the seating / retaining element, for example by lifting the plate or the seating / retaining element off the ground. A person skilled in the art may design the mechanical connection such that in order to lift the plate or the seating / retaining element, additional effort or additional release of the connection is required to separate the plate and the seating / retaining element. 【0097】 The additional effort may be achieved, for example, by a jamming and / or latching mechanical connection. The mechanical connection may, for example, be a dovetail joint as known according to the current teaching. In the arrangement of the seating / retaining element, the receiving device may have a bias that prevents the release of the seating / retaining element and / or the movement of the seating / retaining element relative to the plate. 【0098】 The mechanical connection may also include a partial surface that is oriented at an angle and thus not parallel to the separation movement of the plate and the seating / retaining element, so that said partial surface acts as a locking surface, and separation of the plate and the seating / retaining element is only possible upon deformation of said locking surface. Preferably, the locking surface is made of an elastic material. The locking surface may prevent movement of the element in that the element moves relative to the locking surface and the locking surface prevents further movement of the element in the direction of the locking surface. 【0099】 The seating / retention element applied to the first side or the second side may extend or cover over the entire extension of the respective side or over a sub-region of the respective side. 【0100】 The vehicle of the present invention comprises: a receiving device for arranging a seating / retaining element is formed for use as a seating element, The seating / holding element arranged in a horizontal position is provided with a seating means on its surface opposite the first side or the second side, The present invention may be characterized in that: 【0101】 The receiving device and the seating / holding element may have matching shapes to place the seating / holding element in its horizontal position. The horizontal position may be defined by contact of the matching shapes. 【0102】 The seating / retention element may comprise seating means on which a child may be seated. The seating means may have the shape of a saddle providing good support for the child. 【0103】 The seating / retaining element, which is designed to seat on the seating / retaining element, is arranged above the plate and is connected to the plate via respective lateral receiving devices for force transmission, the connection being preferably made in a releasable manner to allow a universal design of the vehicle of the invention. 【0104】 Potential uses of the vehicle of the present invention include a child seated in the seating means accelerating the vehicle with their feet or hands by sliding, gliding or rolling. Additionally, the vehicle can be pulled by another person. 【0105】 The seating / holding element may have a seating / holding element side shape-adapted to the first side and / or the second side, the seating / holding element side may for example comprise a recess, inside which the wheel can be placed when the seating / holding element is placed on the second side. 【0106】 The vehicle of the present invention comprises: A retaining device is disposed adjacent the seating means. The present invention may be characterized in that: 【0107】 The retaining device may be shaped so that it can be held by a child seated on the seating / retaining element. In an advantageous embodiment, the retaining device has a circular or chamfered shape without sharp edges to avoid injuries. The retaining device may, for example, be T-shaped or annular. 【0108】 Preferably, the support device is located at the front or rear end of the vehicle when viewed in the direction of travel, so that a child standing in front or behind the vehicle can hold the support device. Thus, the vehicle of the present invention is useful as a means for learning to walk. 【0109】 The retaining device may be releasably attached to the seating / retaining element. 【0110】 The seating / retaining element may be releasably attached to the plate. Optionally, a retaining device may extend through the seating / retaining element. The retaining device may be used to secure the seating / retaining element to the plate. 【0111】 As mentioned above, the retaining device may be disposed adjacent to the resting surface.

A receiving device formed as a releasable mechanical connection means has the advantage that the arrangement of the vehicle shown in Figures 1 and 2 can be achieved by removing and installing the seating / holding element 8. 【0247】 The vehicle shown in Figures 1 and 2 having a removable and attachable seating / holding element is a vehicle according to claim 1, optionally read together with at least one claim dependent thereon. 【0248】 The seating / retaining element 8 and the plate 1 may also be made in one piece. 【0249】 The vehicle shown in Figures 1 and 2 in which the plate 1 and the seating / retaining element 8 are integrally formed is a vehicle according to claim 2, optionally read together with at least one claim dependent thereon. 【0250】 The embodiment shown in the top left of FIG. 1, which does not include a seating / retention element 8, is not an embodiment of the present invention. 【0251】 The embodiment shown in the top right of FIG. 1, which does not include a seating / retention element, is not an embodiment of the present invention. 【0252】 The embodiment shown in the bottom left of FIG. 1 is an embodiment of the invention according to claim 1 or claim 2, optionally read together with at least one dependent claim. 【0253】 The vehicle of the present invention comprising the plate 1 and the seating / holding element 8 may be rolled over a ground surface 6, the upper side of which forms a seating means 9, as shown in the bottom left of FIG. 【0254】 The seating / holding element 8 may be arranged on the first side 2 via a releasable receiving device. 【0255】 The seating / retaining element 8 may be formed integrally with the plate 1 , the seating / retaining element 8 being arranged on the first side 2 . 【0256】 The embodiment shown in the bottom right of FIG. 1 is an embodiment of the invention according to claim 1 or claim 2, optionally read together with at least one dependent claim. 【0257】 The seating / retaining element 8 may be arranged horizontally relative to the second side surface 3, the seating / retaining element being formed as a receiving device for the wheels 4, 5. The receiving device of this embodiment and of the further embodiments may be formed according to the description above. 【0258】 Furthermore, the upper side of the seating / retaining element forms a seating means 9 on which a child can be placed. The child may drive the vehicle of the present invention having a first side 2 sliding on a ground surface 6 in a direction of travel 7, as shown in the bottom right of FIG. 【0259】 The horizontal arrangement of the seating / retaining elements 8 on the plate 1 implies that the upper side of the seating / retaining elements forms the seating means 9 . 【0260】 A vehicle of the present invention may have the retaining devices 11 in the positions and arrangements shown. 【0261】 The embodiment shown in the upper part of figure 2 is an embodiment of the invention according to claim 1 (releasable receiving device) or claim 2 (integral formation of plate 1 and seating / retaining element 8) optionally read together with at least one dependent claim. In particular, claim 2 may be combined with claim 22. 【0262】 It is also possible to arrange the seating / holding element 8 on the downwardly facing second side 3 using a second receiving device. The seating / holding element 8 is formed as a receiving device for the wheels 4, 5. The child, which is placed on the first resting surface 18, may move in the travel direction 7 while the vehicle slides on the ground 6, the bottom side of the seating / holding element 8 forming a seating / holding element sliding surface 10 for sliding on the ground 6. The formation of a curved seating / holding element sliding surface 10 for sliding and / or rocking on the ground 6 is also possible. The embodiment shown in the upper part of FIG. 2 is only possible by the removable arrangement of the seating / holding element 8, which is arranged above and thus surrounds the wheels 4, 5. The embodiment shown in the lower part of FIG. 2 is an embodiment of the invention according to claim 1 (releasable receiving device) or claim 2 (integral formation of the plate 1 and the seating / holding element 8), which is optionally read together with at least one dependent claim. 【0263】 The seating / holding element 8 may also be arranged on the plate 1 in a longitudinal position, as shown in the lower part of Fig. 2. The seating / holding element 8 may be arranged in a longitudinal position on the first side 2 (see bottom left of Fig. 2) or on the second side 3 (see bottom right of Fig. 2). In its longitudinal position, the seating / holding element 8 serves as a retaining element for the child standing on the first resting surface 18 or on the second resting surface 19. Depending on the wheels 4, 5 (see bottom left of Fig. 2) or the planar sliding surface (see bottom right of Fig. 2) in contact with the ground 6, the vehicle moves in the direction of travel 7 by rolling or sliding on the ground 6. 【0264】 The longitudinal arrangement of the seating / retaining element 8 requires that the seating / retaining element 8 is made from a rigid, in particular non-flexible, material. 【0265】 The seating / holding element 8 is positioned adjacent to the first side 2 using a first receiving device, as shown in the bottom left of Figure 2. A child resting on the first resting surface 18 may hold onto the longitudinally positioned seating / holding element 8 or a retaining element 11 attached to the seating / holding element 8. 【0266】 The seating / holding element 8 is arranged adjacent to the second side surface 3 by means of a second receiving device, as shown in the bottom right of Fig. 2. The seating / holding element 8 is formed in the area of ​​the second receiving device relative to the receiving device of the front wheel 4. The child resting on the second resting surface 19 may hold on the longitudinally arranged seating / holding element 8 or on a holding element 11 attached to the seating / holding element 8. 【0267】 Instead of providing a releasable receiving device, the formation of the plate 1 and the seating / retaining element 8 is also possible. 【0268】 The representations in Figures 1 and 2 are based on horizontally arranged seating / retaining elements 8 extending over the entire surface of adjacent sides 2, 3. It is also possible for the horizontally extending seating / retaining elements 8 to extend over only a sub-area of ​​the adjacent sides 2, 3, as shown in Figure 3. 【0269】 FIG. 3 shows an embodiment of the invention according to claim 1 (releasable receiving device) or claim 2 (integral formation of plate 1 and seating / retaining element 8), optionally read together with at least one dependent claim. 【0270】 Similar to the representations in Figures 2 and 3, the skilled person can also imagine a longitudinally arranged seating / holding element 8, which extends over the entire adjacent side surfaces 2, 3, which are not shown in Figures 2 and 3. Figures 2 and 3 show a seating / holding element 8, which extends over a sub-region of the side surfaces 2, 3. 【0271】 1 to 3, the receiving device may for example be formed as a connector when designed according to claim 1, optionally read together with at least one dependent claim. The seating / retaining element 8 may be plugged into the plate 1 in the direction dictated by the formation of the connector. 【0272】 The seating / holding element 8 shown in figures 1 to 3 is made of a solid material. The seating / holding element 8 has sufficient inflexibility, especially in its position as a holding element, so that a child standing on the resting surface 18, 19 can be held on the holding element (see the bottom part of figure 2). The seating / holding element 8 has sufficient inflexibility in its position as a seating element on which a child can be seated on the seating means 9 or plate 1 (see the bottom part of figure 1, see the top part of figure 2, see figure 3). 【0273】 FIG. 4 shows an embodiment of the invention according to claim 1 (releasable receiving device) or claim 2 (integral formation of plate 1 and seating / retaining element 8) optionally read together with at least one dependent claim. 【0274】 4 shows a particular embodiment of the receiving device, which may comprise a receiving hinge 20, by means of which the seating / holding element may be attached to the plate 1 so as to rotate or pivot. 【0275】 In an embodiment having a releasable receiving device according to claim 1, optionally read together with at least one dependent claim, the hinge 20 may be formed as a mechanical hinge or from a deformable material. 【0276】 In an embodiment where the plate 1 and the seating / retaining element 8 are integrally formed, the hinge may be formed as a mechanical hinge, and the hinge portion of the hinge 20 cannot be opened. As an alternative to a mechanical hinge, the hinge 20 may be made from a deformable material, which is inserted into a mould, for example by foaming or injecting the plate 1 and the seating / retaining element 8, thus creating a single workpiece. 【0277】 The top left and top right of FIG. 5 show an embodiment of the invention according to claim 4, optionally read together with at least one dependent claim. 【0278】 5 shows a further embodiment of a plate 1, which comprises a first side 2 having a first curved sliding surface. The plate 1 comprises a second side 3 having at least one wheel, in particular at least one front wheel 4 and at least one rear wheel 5. 【0279】 When the wheels 4, 5 contact the ground 6, the vehicle can be moved on the ground 6 rolling in a moving direction 7 with the second side 3 facing down, as shown in the top left of Figure 5. The first side 2 comprises a first resting surface 18. 【0280】 When the first side 2 contacts the curved sliding surface, the vehicle can be moved by rocking and / or sliding on the ground 6 in the moving direction 7, as shown in the upper right of Fig. 5. The second side 3 is provided with a second resting surface 19. 【0281】 The bottom left and bottom right of Fig. 5 show an embodiment of the invention according to claim 1 (releasable receiving device) or claim 2 (integral formation of plate 1 and seating / retaining element 8) optionally read together with at least one dependent claim. The embodiment shown in the bottom left and bottom right of Fig. 5 is also an embodiment according to claim 4 optionally read together with claim 10 and other claims. 【0282】 A horizontally positioned seating / retaining element 8 may be positioned adjacent to the first side 2 using a first receiving device, with the upper side of the seating / retaining element 8 acting as a seating means 9. This is shown in the bottom left of FIG. 【0283】 The horizontally arranged seating / retaining element 8 may be arranged adjacent to the second side 3 using a second receiving device, the upper side of the seating / retaining element 8 serving as a seating means 9. This is shown in the bottom right of Fig. 5. In a sub-area, the seating / retaining element is implemented to be hollow in order to receive the present wheels 4, 5. 【0284】 The embodiment shown is preferably formed such that the retaining element 11 is positionable adjacent the seating means 9 . 【0285】 Figure 6 shows an embodiment of the invention according to claim 1 (releasable receiving device) or claim 2 (integral formation of plate 1 and seating / retaining element 8), optionally read together with at least one dependent claim. The embodiment shown in Figure 6 is also an embodiment according to claim 4, optionally read together with claim 10 and at least one other dependent claim. 【0286】 If the vehicle of the invention is formed according to claim 1, FIG. 6 shows another arrangement of the vehicle of the invention in relation to FIG. 5, in which the longitudinal seating / retaining element 8 is arranged on the first side 2 (see the left side of FIG. 6) or on the second side 3 (see the right side of FIG. 6). 【0287】 The upper part of FIG. 7 shows an embodiment of the vehicle invention as defined in claim 3, which is optionally read together with the further claims. 【0288】 The top part of Fig. 7 shows another embodiment of the plate 1, which comprises a first side 2 with a planar sliding surface and a second side 3 with a planar sliding surface. The sides 2, 3 are opposite sides of the plate 1, which are formed parallel to each other in the special form shown in Fig. 7. The sides 2, 3 form the top and bottom sides of the plate 1. 【0289】 The sliding surfaces extend over the entirety of each side or over sub-areas of each side. The sliding surfaces have different sliding properties for sliding on the ground 6. 【0290】 The lower part of FIG. 7 and FIG. 8 shows an embodiment of the invention according to claim 3, which is optionally read together with at least one dependent claim. 【0291】 The seating / retaining element 8 may be arranged adjacent to the first side 2 in a horizontal position (see bottom left of FIG. 7) and in a vertical position (see left of FIG. 8). Furthermore, the seating / retaining element 8 may be arranged adjacent to the second side 3 in a horizontal position (see bottom right of FIG. 7) and in a vertical position (see right of FIG. 8). Such an arrangement is effected via a releasable receiving device in case of implementation according to claim 1 or via integral formation in case of integral formation of the plate 1 and the seating / retaining element 8. 【0292】 The seating / holding element is formed in one piece so that the holding element can be held by a child standing on the resting surfaces 18, 19. This is achieved by forming the seating / holding element from a solid material which also allows the child to sit on the seating means 9. 【0293】 The embodiment of figures 7 and 8 features different sliding characteristics resulting in different sliding movements. The child as a user can selectively contact the first side 2 or the second side 3 with the ground 6, thereby selecting the sliding characteristics of the vehicle of the invention. This applies to all arrangements of this embodiment of the vehicle of the invention shown in figures 7 and 8. 【0294】 The upper part of FIG. 9 shows an embodiment of the invention according to claim 4, optionally read together with at least one dependent claim. 【0295】 Figures 9 and 10 (bottom) show another embodiment of the vehicle of the invention in a different arrangement according to claim 4, optionally read together with at least one dependent claim. 【0296】 The first side 2 has a curved sliding surface. When the first side 2 contacts the ground 6, the vehicle can be moved by rocking and / or sliding on the ground 6 in the moving direction 7. The second side 3 on the upper side of the plate 1 can function as a second resting surface 19 (see the top right of FIG. 9). 【0297】 The second side surface 3 has a sliding surface formed in a flat shape. When the second side surface 3 comes into contact with the ground 6, the vehicle of the present invention slides and moves in the running direction 7. The first side surface 2 as the upper side of the plate 1 can function as a first retention surface 18 (see the upper left of FIG. 9). 【0298】 Furthermore, the seating / holding element 8 may be in contact with the first side 2 (see bottom left of FIG. 9) or with the second side 3 (see bottom right of FIG. 9), and the upper side of the seating / holding element 8 may function as a seating means 9. The embodiment shown in the lower part of FIG. 9 and in FIG. 10 is an embodiment of the invention based on the seating / holding element 8 arranged on one side. The seating / holding element 9 may then be arranged in a vertical position adjacent to the first side 2 (see left side of FIG. 10) or adjacent to the second side 3 (see right side of FIG. 10), so that a child standing on the first resting surface 18 or the second resting surface 19, respectively, can hold the seating / holding element 8. In the above-mentioned positions, the seating / holding element 8 may be provided with a retaining element 11. 【0299】 The sliding surfaces of the first side 2 and the second side 3 may have different sliding characteristics. The vehicle of the present invention may have different running characteristics depending on which side 2, 3 contacts the ground 6 due to different sliding characteristics and / or different designs of the sliding surfaces. 【0300】 Figures 11 and 12 show another embodiment of the vehicle of the present invention according to claim 5, optionally read together with at least one claim 5. The first side 2 and the second side 3 are provided as curved sliding surfaces, such that the vehicle of the present invention can be moved sliding and / or rocking in the moving direction 7 when the first side 2 or the second side 3 contacts the ground 6. 【0301】 The first side 2 and the second side 3 are sliding surfaces with similar or equal curvature. The sides 2, 3 may also have differently curved sliding surfaces. 【0302】 The sliding surfaces of the lateral sides 2, 3 may also have different sliding properties. 【0303】 The vehicle of the invention may have different driving characteristics depending on which side 2, 3 comes into contact with the ground 6 due to different sliding characteristics and / or different designs of the sliding surfaces. 【0304】 11 and 12 then show the arrangement of the seating / holding element 8 in a horizontal position (see the bottom of FIG. 11) and in a vertical position (see FIG. 12) via a removable receiving device. The above description of the figures is equally applicable to FIGS. 11 and 12. 【0305】 Instead of a releasable receiving device, an integral formation of the plate 1 and the seating / retaining element 8 may also be provided. 【0306】 Figure 13 shows another embodiment of the invention according to claim 1, optionally read together with another dependent claim. Figure 13 also shows an embodiment according to claim 4, optionally read together with dependent claim 15 and claim 4, optionally read together with another dependent claim. 【0307】 Figure 13 shows another feature of the vehicle of the present invention based on the example embodiment shown in Figures 1 and 2. However, this feature is also applicable to other embodiments of the vehicle. 【0308】 13 shows the features of wheels 4, 5 that can be introduced into the plate 1. This requires that the plate is sufficiently thick and hollow in at least each sub-area of ​​the plate 1 to form a receiving space for receiving the wheels 4, 5. 【0309】 The top left of Figure 13 shows a first use of the vehicle of the invention according to claim 4 read together with claim 15, where the vehicle is moved in a moving direction 7 on wheels 4, 5 by rolling on a ground surface 6. The first side 2 on the upper side may serve as a resting surface 18. 【0310】 At least one wheel 4, 5 may be displaced within the plate 1. The bottom left of Fig. 13 shows the wheels 4, 5 in a retracted position so that the vehicle can be slidably moved in the direction of travel 7 when the second side 3 contacts the ground 6. The bottom left of Fig. 13 and the bottom right of Fig. 13 therefore show an embodiment of the invention according to claim 4, which is optionally read together with claims 15 and 22 and at least one dependent claim. 【0311】 When the first side 2 contacts the ground 6, the second side 3 serves as a second resting surface 19, and the wheels 4, 5 introduced into the plate 1 do not interfere. 【0312】 The description of FIG. 13 refers to the plate 1 being formed with a thickness necessary to accommodate the wheels 4, 5. Regardless of the features that introduce the wheels 4, 5 into the plate 1, forming the plate 1 with a greater thickness, and thus forming the plate 1 as a rectangular parallelepiped, may provide the advantages described in FIG. 14. 【0313】 Figure 14 shows an embodiment of the invention according to claim 1 or according to claim 4, which are read together with claim 22. These embodiments of the invention may have the features of the other dependent claims. 【0314】 The left side of Fig. 14 shows the plate 1 in a front view. The plate 1 has a rectangular cross section with a first side length 21 and a second side length 22. Since the rectangular parallelepiped as the plate 1 includes, in addition to the sides 2, 3, two further sides 23, 24 included in Fig. 14, thus four sides 2, 3, 23, 24, the plate 1 can be placed in four different positions by orienting any of the four sides 2, 3, 23, 24 towards the ground 6. The latter includes the use of any of the sides 2, 3, 23, 24 as sliding surfaces for sliding or rocking movements, or the use of wheels for rolling movements on the ground 6. 【0315】 If the first side length 21 and the second side length 22 are different, the upper side of the plate 1 will be located at different respective heights from the ground 6, as shown in FIG. 【0316】 In realising claim 4, the four side surfaces 2, 3, 23, 24 have different sliding characteristics regardless of the design of the side surface lengths 22, 23. 【0317】 Figure 15 shows an embodiment of the invention according to claim 1 or claim 3 or claim 4 or claim 5 read together with claim 17. This embodiment may also have the features of the further dependent claims. Removable seating / retention elements are not included in figure 15. 【0318】 The plate 1 can comprise a first plate part 25 and a second plate part 26. The plate parts 25, 26 arranged behind each other as seen in the direction of travel 7 are connected in an exemplary manner via a hinge 14, so that the plate parts 25, 26 can be set relative to each other to achieve a steering effect, as shown by the arc-shaped arrow in Figure 15. Such a steering effect can be achieved both for a rolling movement of the vehicle (see the left side of Figure 15) and for a sliding movement of the vehicle (see the right side of Figure 15). 【0319】 The hinge 14 may be implemented as a ball hinge. The hinge 14 may also include an adjustment axis, which is oriented at an angle of 90° to the side surfaces 2, 3 or the ground 6. 【0320】 Figure 16 shows an embodiment of the invention according to claim 1 or claim 3 or claim 4 or claim 5 read together with claim 17. This embodiment may also have the features of the other dependent claims. The removable seating / retaining element 8 is not included in figure 16. 【0321】 Figure 16 shows another way in which the hinges can be set up: the plate 1 comprises a front plate sub-region 12 and a rear plate sub-region 13. The sub-regions 12, 13 are connected via a hinge 14, which comprises a hinge axis extending parallel to the extension direction of the plate 1. 【0322】 The rear plate sub-region 13 is provided with wheels 5 on its first side 2 and with wheels 5' on its second side 3. The wheels 5, 5' symbolize that the first side 2 and the second side 3 of the rear plate sub-region 13 generally have different movement characteristics on the ground 6. In the case of the wheels 5, 5' these are different rolling characteristics on the ground 6. Instead of one or more wheels 5, 5' the skilled person may also provide a sliding surface on the first side 2 and / or the second side 3, thus establishing different movement characteristics of the sides 2, 3 on the ground 6. 【0323】 The hinge 14 allows selective setting of the sliding surface relative to the wheels 5, 5' or the ground 6 so that different movement characteristics can be produced. 【0324】 An embodiment will now be described on the basis of figures 17, 18 and 19, of which an unpublished prototype has been developed. Figures 17 and 18 show views of the sides 2, 3 of the plate 1. Figure 19 shows a perspective front view and a perspective rear view of the vehicle of the invention. 【0325】 Provided that the seating / retention element is removable, the vehicle shown in Figures 17, 18 and 19 is an embodiment according to claim 1, optionally read together with at least one dependent claim. 【0326】 In a hypothetical integral formation of the plate and the seating / holding element, the vehicle shown in figures 17, 18 and 19 is an embodiment according to claim 2, which is optionally read together with at least one dependent claim. The children's vehicle of the invention comprises a plate 1 having a first side 2 (see the diagram in figure 17) and a second side 3 (see the diagram in figure 18), the sides 2, 3 being arranged opposite each other. The plate 1 therefore has a certain thickness, which is selected by the skilled person in order to achieve the required stability and with regard to fulfilling the following structural characteristics: 【0327】 FIG. 19 shows two perspective views of the vehicle of the present invention. 【0328】 The first side 2 comprises four first sliding surfaces 30, 31, 32, 33. The first sliding surfaces 30, 31, 32, 33 have a first sliding characteristic when in contact with the ground 6. The first sliding characteristics of the first sliding surfaces 30, 31, 32, 34 may be different from each other or may be paired. In the prototype shown in FIG. 17, the first sliding surfaces 30, 31 have a first surface extension, while the first sliding surfaces 32, 33 have a smaller first surface extension. In the prototype shown, the first sliding surfaces 30, 31, 32, 33 are formed from the same surface material, although this is by no means a requirement. 【0329】 The sliding surfaces 30, 31, 32, 33 may also be made from different materials. 【0330】 The first sliding surfaces 30, 31, 32, 33 extend over sub-areas of the first side 2. The first sliding surfaces 30, 31, 32, 33 are arranged at the corners of the first side 2 of the plate 1. 【0331】 The first sliding surfaces 30, 31, 32, 33 are formed as flat surfaces. The first sliding surfaces 30, 31, 32, 33 include elongated grooves 28, and for the sake of clarity, only the elongated groove of the first sliding surface 30 is indicated by the reference number 28. Each sliding surface 30, 31, 32, 33 is smoothly implemented between each elongated groove 28. 【0332】 The longitudinal extension of the sliding surfaces 30, 31, 32, 33 may be oriented at an acute outward angle with respect to the direction of movement 7. Similarly, the elongated groove 28 may be oriented at an acute outward angle with respect to the direction of movement 7. 【0333】 The first sliding surfaces 30, 31, 32, 33 are formed at a height distance up to the first surface 29 of the first side surface 2. When sliding on a flat ground (see FIG. 17), the first surface 29 does not contact the ground 6. Since the first sliding surfaces 30, 31, 32, 33 are implemented as partial surfaces of the first side surface 2, only the first sliding surfaces 30, 31, 32, 33 contact the ground 6. It is also generally possible to form the entire first surface 29 as a sliding surface. 【0334】 The sliding surfaces 30, 31, 32, 33 are provided with a recess 41 for receiving an element with special sliding properties, for example a felt element. The recess 41 is indicated only by the reference number in the sliding surface 30. Two sub-areas in the sliding surface 30 are formed with different sliding properties by the introduced pieces of felt. 【0335】 One of the sliding surfaces 30, 31, 32, 33 may also be made entirely from felt or Teflon or another material having selected sliding properties. 【0336】 The first side 2 comprises a first retention surface 18. Here, the first retention surface 18 has the particular shape of a recess 16. The first retention surface 18 may also be a more unspecified sub-area of ​​the first surface 29. It is not necessary to show a representation of the first retention surface 18, since the child should be able to retain it on the first side 2 in any shape or form. 【0337】 The first side 2 is provided with a groove 34, which serves as a receiving device for a seating / retaining element 8 arranged adjacent to the first side 2. The seating / retaining element 8, which has a corresponding shape of a receiving device, not shown in FIG. 17. Providing a tongue and groove as receiving device is a possible advantageous form of the receiving device. Other forms of mechanical connection are also possible. 【0338】 In particular, the tongue and groove connection can be implemented as a releasable connection of the seating / retaining element 8 to the plate 1. In a preferred embodiment, the releasably formed tongue and groove connection is a clamp, so that the connection is released by overcoming the clamping force. 【0339】 In particular, the tongue and groove connection can be implemented as an integral connection between the plate 1 and the seating / retaining element 8. The plate 1 and the seating / retaining element 8 may have a bond in the area of ​​this connection. 【0340】 In the special case shown in figures 17 and 18, the receiving device extends in a sub-region following the periphery of the plate 1. It therefore follows the arcuate shape of the front plate region 12 and the rear plate region. Diverting forces acting tangentially on the plate 1 in all directions from the seating / retaining element is achieved by this special shape of the receiving device. 【0341】 The plate 1 has a tapered shape. It has a greater width in the front plate region 12 and in the rear plate region 13, seen in the direction of movement 7, than in the central region of the plate 1. The advantages achievable thereby are explained below on the basis of FIG. 【0342】 FIG. 18 shows a top view of the second side 3 of the plate 1. In FIG. 17, the second side 3 is in contact with the ground 6, whereas in FIG. 18, the first side 2 is in contact with the ground 6. The child may determine the running characteristics of the vehicle of the invention by orienting the first side 2 and the second side 3 towards the ground 6. In the position of the plate 1 of the vehicle shown in FIG. 17, the running characteristics of the vehicle are determined by the characteristics of the second side 3, in particular the sliding characteristics of the first side 2 with the ground 6. In the position shown in FIG. 18, the running characteristics of the vehicle are determined by the characteristics of the first side 2, in particular the rolling characteristics of the wheels 4, 5 shown in FIG. 18 on the ground 6. Various designs of the sides 2, 3 to achieve specific characteristics of the sides 2, 3 against the ground 6 have been described in detail above and are mentioned only by way of example in the description of the prototype. The prototype may also have other designs of the sides 2, 3 mentioned above, instead of a planar sliding surface on the first side 2 and wheels on the second side 3. 【0343】 The second side 3 is provided with wheel suspensions and wheel cases 35, 36, 37, 38 for receiving wheels 4, 5 which are not visible in FIG. 【0344】 The wheel is oriented with the second side 3 towards the ground 6 and the second surface 39 away from the ground 6 . 【0345】 It should be noted that the second side surface 3 has a recess 16 as the second retention surface 19, and in this regard, the formation of the second retention surface 19 is not limited to this shape. Also, the shape of the second retention surface 19 may be made different to retain the child on the second side surface 3. 【0346】 The tapered shape of the plate 1 is also clearly shown in figure 18. In a preferred, and therefore non-limiting manner, the first side 2 and the second side 3 are of congruent shape. 【0347】 Like the first side 2, the second side 3 is provided with a groove 34 as a receiving device and the seating / retaining element is provided with a matching tongue as a receiving device. 【0348】 The first side 2 and the second side 3 may comprise a spacing element 42, which spaces the first surface 29 and the second surface 39, respectively, from the surface of the seating / holding element 8, at least in the region of the spacing element 42. If the spacing element 42 has a sufficiently large height extension, the contact or distance between the plate 1 and the seating / holding element 8 can preferably be formed by the spacing element 42. By such spacing element 42, noise caused by relative movements between the plate 1 and the seating / holding element 8 can be prevented or the seat height can be adjusted. 【0349】 Fig. 19 shows a front and rear perspective view of a vehicle of the invention, which comprises a plate 1 and a seating / retaining element 8. As explained in detail above, the seating / retaining element 8 may be arranged adjacent to the first side 2 or adjacent to the second side 3. In Fig. 19 only the arrangement of the seating / retaining element 8 adjacent to the second side 3 is shown. An arrangement of the seating / retaining element 8 adjacent to the first side 2 is also possible. 【0350】 The plate 1 contacts the ground 6 at a first side 2. The plate 1 is provided with sliding surfaces 30, 31, 32, 33 on its first side 2 and may be moved in a moving direction 7 by sliding on the ground 6. 【0351】 The seating / holding element is arranged horizontally. On its inner side, the seating / holding element receives the wheels arranged on the second side 3. The seating / holding element 8 comprises a seating means 9 for the child on its upper side. In an advantageous non-limiting manner, the seating means 9 has the shape of a saddle. Thus, in order to facilitate the child to place his / her feet on the ground 6, the seating / holding element 8 has a tapered shape that corresponds to the shape of the plate 1 described above. The seating / holding element 8 and the plate 1 have a tapered shape in the central region, with a greater width in the front region of the seating / holding element 8 adjacent to the front plate region 12 and in the rear region of the seating / holding element 8 arranged adjacent to the rear plate region 13. 【0352】 Furthermore, the seating / holding element 8 and the plate 1 have a concave shape in the rear region 12. This shape is advantageous to allow free movement of the child pushing the vehicle, in particular space for the feet or knees. 【0353】 The seating / retaining element 8 is provided in its front area with a receiving device 40 for a retaining device 11, which is shown in FIG. 【0354】 The plate 1 and the seating / retaining element 8 may be made of foam. This material is advantageous due to its light weight and elastic deformability. The receiving device 40 for the retaining device is provided with reinforcements for deflecting forces within the seating / retaining element 8. 【0355】 In an advantageous embodiment, the plate 1 comprises a recess 16 which forms a storage space 15 for receiving an object such as a toy or a resting surface 18, 19. The recess 16 is advantageous in that it prevents a child or an object contained in the storage space 15 from shifting or falling. 【0356】 The embodiment shown in Figures 17, 18 and 19 is also characterized by a hollow implementation of the seating / holding element, such that the storage space 15 is formed by the recess 16 and the hollow area of ​​the seating / holding element. 【0357】 Preferably, the width of the plate (measured transversely to the direction of travel 7 in the front plate area 12 or the rear plate area 13) is large or greater than the seat height (distance from the highest point of the seating means 9 to the ground 6), thereby preventing the vehicle from tipping over. 【0358】 Figure 20 shows another embodiment of the vehicle of the invention according to claim 1 (releasable receiving device) or claim 2 (non-releasable receiving device, optionally read together with at least one dependent claim). The plate 1 comprises a first side 2 with a sliding surface which is flat (in the particular form shown). A curved sliding surface or any other design of the first side 2 as described herein is also possible. 【0359】 In the special wheeled configuration shown in figure 20, the plate 2 is provided with a second side surface 3. Other designs of the second side surface 3 are possible. 【0360】 The vehicle further comprises a seating element 8, which is coupled to the plate 1 via a receiving device. The receiving device is formed as at least one receiving hinge 20, which is included in the plate 1. The hinge axis of the receiving hinge 20 extends parallel to the extension axis of the plate 1, seen in the direction of movement 7. Figure 20 shows the special case of a plate 1 with receiving hinges 20 at both ends. 【0361】 By pivoting the plate 1 about the hinge axis relative to the element 8, the first side 2 or the second side 3 can be selectively oriented towards the ground, thereby setting the vehicle's dynamic characteristics. 【0362】 20 further shows the special case of a hinge axis arranged eccentrically with respect to the height extension of the plate 1, optionally including the wheels, whereby a height adjustment of the seating means 9 on the upper side of the element 8 may also be achieved. 【0363】 Figure 21 shows another embodiment of the vehicle of the invention (releasable receiving device) according to claim 1, optionally read together with at least one dependent claim. Similar to the embodiment shown in figure 20, the plate 1 comprises two sides with different movement characteristics on the ground 6. 【0364】 The seating element 8 is removably coupled to the plate 1 via a receiving device. The seating element 8 also contacts the ground 6 and forms a further sliding surface. 【0365】 FIG. 22 shows a further embodiment of the vehicle of the invention as defined in claim 1 (releasable receiving device) or claim 2 (non-releasable receiving device, optionally read together with at least one dependent claim). 【0366】 The plate 1 comprises a first side 2, which is formed as a sliding surface. Figure 22 shows a planar sliding surface, curved sliding surfaces are also possible. 【0367】 The plate 1 is provided with a second side 3, which in the special case shown in Fig. 22 is provided with wheels 4, 5. The second side 3 may also be provided with a planar or curved sliding surface instead of the wheels 4, 5. 【0368】 The seating / holding element 8 is connected to the first side 2 via a receiving device. The receiving device is formed by a receiving hinge 20, which is included in the plate 1. The seating / holding element 8, hinged to the first side 2 via the receiving hinge 20, may be transformed from a horizontal position as seating means 9 to a vertical position as holding device 11 by rotating or pivoting, preferably when the second side 3 contacts the ground 6. 【0369】 Advantageously, the plate is provided with a recess which serves as a storage space 43. This storage space 43 can be sealed by element 8 as seating means 9. It is also possible to provide a further element which, like element 8, is supported for rotation and which can be used as a retaining device in the folded position. 【0370】 When the first side 2 contacts the ground 6, the seating / retention element acts as a sliding surface. 【0371】 Figure 23 shows another embodiment of the invention according to claim 1 (releasable receiving device) or claim 2 (non-releasable receiving device, optionally read together with at least one dependent claim). In particular, Figure 23 shows a potential formation of the sliding surface with reference to the embodiment shown in the top right corner of Figure 9. The following is also applicable to other possible embodiments of the sliding surface. 【0372】 The depiction of one embodiment of the vehicle of the invention on the left side of Fig. 23 shows a sliding surface having protrusions 44. The protrusions 44 may be dot-like or may be formed to extend across the width of the sliding surface (perpendicular to the image plane). As shown on the left side of Fig. 34, the protrusions 44 may be implemented in sub-areas of the sliding surface or may be distributed across the entire partial surface. 【0373】 The depiction of one embodiment of a vehicle of the present invention on the right hand side of FIG. 23 shows a sliding surface having projections 44 extending in a linear or planar fashion. 【0374】 In both embodiments, the projections 44 are popped, thereby producing a motivating sound for the child during the rocking motion. 【0375】 The formation of a sliding surface having such protrusions 44 can be regarded as the formation of a multi-curved sliding surface having a continuous sliding surface. 【0376】 Figure 24 shows in cross section a detail of an advantageous configuration of the sliding surface of the first side 2 or the second side 3. The sliding surface may be a sliding surface as described above. This detail is applicable to the embodiment of the invention. 【0377】 The edge 45 of the sliding surface is located at a distance from the edge 46 of the side surface 2. In the area between the edges 45, 46, the first surface 29 of the plate 1 does not contact the ground. A person skilled in the art can select the distance between the edges 45, 46 so that a child can get his / her hands in that area, but not between the sliding surface 39 and the ground 6. This prevents a child from getting his / her hands or toes stuck between the ground 6 and the sliding surface 39. 【0378】 Figure 25 shows another embodiment of the vehicle of the invention according to claim 3 or claim 5, optionally read together with at least one dependent claim, and a potential combination of the vehicle of the invention with a scooter, kick scooter, etc. In the following, the term "scooter" is selected, which scooter may have weight shift steering and / or turn steering. 【0379】 The scooter comprises a carriage 47 having at least one front wheel 4 and at least one rear wheel 5. A holding device 11 is connected to the plate 1. The carriage 47 extends substantially between the front wheel 4 and the rear wheel 5. Furthermore, the seating means 9 is connected to the holding device 11 by mechanical connection means. The seating means 9 can be released from the holding device 11. 【0380】 In a potential embodiment of the invention, the vehicle of the invention may be formed with seating means 9 in the position shown on the left side of Figure 25. The vehicle of the invention may also be positioned under the scooter shown in the figure such that the seating means 9 forms a plate 1 having a first side 2 and a second side 3, as shown in the center of the right side of Figure 25. 【0381】 In all cases shown in Figure 25, the vehicle of the invention is provided with a receiving device for connecting the vehicle of the invention directly (see the left side of Figure 25) or indirectly (see the centre and right side of Figure 25) to the retaining element 11 of the scooter. 【0382】 The formation of the side surfaces 2, 3 is not limited to the side surfaces 2, 3 shown in Fig. 25. Those skilled in the art can apply the above description to Fig. 25. 【0383】 Figure 26 shows another embodiment of the vehicle of the invention according to claim 1 (releasable receiving device) or claim 1 (integral formation of plate and seating / retaining element). The embodiment shown in Figure 26 may also be regarded as an embodiment according to claim 4 or claim 5, optionally read together with claim 10 and at least one independent claim. 【0384】 The elements 8, 8' are arranged on one side 2 of the plate 1, the elements 8, 8' forming another sliding surface. The elements 8, 8' may be formed as sliding plates. The sliding plates may be releasably attached to the first side 2, for example by means of plugging. The sliding plates may be embodied as curved shapes as described above. 【0385】 FIG. 27 shows at least one embodiment according to claim 1 (releasable receiving device) or claim 2 (non-releasable receiving device), optionally read together with at least one dependent claim. 【0386】 27 shows another embodiment of the present invention. The vehicle of the present invention may also comprise a first plate 1 and a second plate 1', which can be set relative to each other. The first plate 1 and the second plate comprise sides 2, 3, 2', 3' and sides 2', 3', respectively, which can selectively contact the ground 6. 【0387】 A seating element 8 may be added to the plates 1, 1', one or more of the plates 1, 1' being provided with a receiving device as a receiving device for the element 8. The element 8 may be provided with a holding device 11. 【0388】 The individual positions are shown in FIG. 27 and the skilled person can also apply the above description to form the sides 2, 3 as flat or curved sliding surfaces or with wheels. 【0389】 Figure 28 illustrates the embodiment shown in the top left of Figure 27 using an exploded view. The embodiment shown in Figure 28 is an embodiment according to claim 3 or claim 4 or claim 5, optionally read together with at least one dependent claim. 【0390】 The embodiment shown in FIG. 28 comprises a plate having a first plate 1 and a second plate 1′. 【0391】 The first plate 1 and the second plate 1' are releasably connected to each other. The releasable connection may be established by an interference fit. Figure 28 shows a possible embodiment of a releasable interference fit connection, which is described below. Further releasable interference fit connections are possible. 【0392】 The first plate 1 comprises a first side 2, which is formed as a curved sliding surface. Figure 28 shows the special case where the first side 2 is curved about a single axis, which is oriented at an angle of 90° to the direction of movement 7. First side 2 curved about further axes, and thus curved about multiple axes, are also possible. 【0393】 In the embodiment shown in FIG. 28, the first side 2 of the first plate 1 contacts the ground, which is not included in FIG. 【0394】 The first side 2 of the first plate 1 forms a first resting surface 18. The infant may be rested on the curved surface by sitting or standing. 【0395】 The first plate 1 is provided on its second side 3, thus opposite the first side 2, with a first opening 50 into which the second plate 1' can be inserted, thus partially, up to a stopper 53. The stopper 53 limits the insertion depth of the first plate 1' into the second plate 1". The second plate 1' can be partially releasably inserted into the first opening 50, in that the second side 3' of the second plate 1' can be brought into contact with the ground. 【0396】 The infant may sit in the first opening, the closure of which may function as a second resting surface 19 of the first plate 1 . 【0397】 The second plate 1' has a second side surface 3'. The second side surface 3' is formed in a planar shape with a hump. Forming a hump on a planar sliding surface is a special case. It is also possible to form the second side surface 3 without a hump. The hump may be hemispherical, etc. 【0398】 The infant may be placed on the second side 3' of the second plate 1'. The second side 3' of the second plate 1' is the second placement surface 19 of the second plate 1'. 【0399】 The second plate 1' comprises a first side 2' on which the wheels 4', 5' are arranged. The front wheels 4' are configurably implemented via a steering mechanism. The rear wheels 5' are not configurably implemented. The child may be placed on a first resting surface 18' of the second plate 1' between the wheels 4', 5'. The first side 2' of the second plate 1' thus represents the first resting surface 18' of the second plate 1'. 【0400】 The first plate 1 surrounds the peripheral area of ​​the second plate 1 ′ when the second plate 1 ′ is inserted into the first opening 50 . 【0401】 The releasable connection of the plates 1, 1' is achieved via a first opening 50 in the second side 3 of the first plate 1, into which the second plate 1' can be inserted. The second plate 1' can be inserted into the first plate 1 with its first side 2' or its second side 2' facing outwards. 【0402】 This allows the first side surface 2 of the first plate 1, or the first side surface 2' of the second plate 1', or the second side surface 3' of the second plate 1', to come into contact with the ground. Preferably, the first plate 1 includes a stopper 53 for limiting the insertion depth of the second plate 1' into the first opening. The second plate 1' inserted into the first opening 50 comes into contact with the first side surface 2' or the second side surface 3' of the stopper 53. 【0403】 The formation of the plates 1, 1' is applicable to FIGS. 【0404】 Figure 29 shows, using an exploded view, the embodiment shown in the middle left of Figure 27. The plates 1, 1' of the embodiment shown in Figure 29 correspond to the embodiment shown in Figure 28. However, the plates 1, 1' are arranged in a different arrangement. 【0405】 The embodiment shown in FIG. 29 is an embodiment as defined in claim 3 or claim 4 or claim 5, which is indicated to be read optionally together with at least one dependent claim. 【0406】 The first side 2 of the first plate 1 in Fig. 28 does not contact the ground, which is not included in Fig. 28, while the second side 3' of the second plate 1' in Fig. 29 faces the ground, which is not included in Fig. 29. In Fig. 28, the second side 3' of the second plate 1' can function as a resting surface. In Fig. 29, the first side 2 of the first plate 1 functions as a resting surface. 【0407】 Figure 30 shows another arrangement of plates 1, 1' as shown in the middle left part of Figure 27. The embodiment shown in Figure 30 is an embodiment according to claim 3 or claim 4 or claim 5, which is indicated to be read optionally together with at least one independent claim. 【0408】 The plates 1, 1' are formed like the plates in Figure 28 or Figure 29. In Figure 30 the plates 1, 1' are arranged relative to each other in a different arrangement than in Figure 28 or Figure 29. 【0409】 30, the first side surface 2' of the second plate 1' faces the ground. The first side surface 2 of the first plate 1 becomes the placement surface 18. 【0410】 The seating / retaining elements may be releasably arranged in the embodiment shown in Figure 28 or Figure 29 or Figure 30, thereby achieving the embodiment shown in Figures 31, 32, 33. Thus, the description of Figures 28, 29 and 30 is applicable to the design of plates 1, 1' therein. 【0411】 Using an exploded three-dimensional view, a cross-section and a top view, FIG. 31 illustrates the embodiment shown in the upper center and upper right corners of FIG. 【0412】 FIG. 31 or FIG. 32 or FIG. 33 show an embodiment according to claim 3 or claim 4 or claim 5, optionally read together with at least one independent claim. 【0413】 The embodiment shown in Fig. 31 comprises a removable seating / retaining element 8 with a retaining device 11 in addition to the plates 1, 1'. The seating / retaining element 8 has an opening 52 on the side facing the first plate 1 and / or the second plate, into which the first plate 1 and / or the second plate 1' can be partially inserted. The seating / retaining element 8 and the opening 52 are formed in particular such that the first plate 1 or the second plate 1' facing the ground contacts said ground. Preferably, the seating / retaining element 8 comprises a stopper 54 in the opening 52, which limits the insertion depth of the plates 1, 1' into the opening. 【0414】 The seating / holding element 8 comprises a resting surface on which the holding device 11 is located opposite the opening 52. The resting surface and the holding device 11 are formed in such a way that the holding device 11 can be grasped by a child, for example in a sitting position on the resting surface as the seating means 9. 【0415】 The embodiment shown in FIG. 31 can be converted into various other arrangements, which is why the connection between the plates 1, 1' with the seating / retaining element 8 and one of the plates 1, 1' is made releasable. 【0416】 The arrangement shown in FIG. 31 allows for rocking or sliding on the ground. 【0417】 The arrangement shown in Figure 31 may be redesigned as shown in Figure 32. The embodiment shown in Figure 32 allows for sliding on the ground, with the hump on the second side 3' of the second plate 1' in contact with the ground. 【0418】 The arrangement shown in Figure 31 may be redesigned to that shown in Figure 33. The embodiment shown in Figure 33 allows rolling on ground with the wheels 4', 5' in contact with the ground on the first side 2' of the second plate 1'. 【0419】 Figures 34 and 35 show cross-sectional views of the embodiment shown in Figures 17, 18 and 19. Figure 34 shows a cross-sectional view with a cross-sectional plane that is perpendicular to the longitudinal axis of the plate 1 and perpendicular to the direction of movement 7 when traveling straight ahead. Figure 35 shows a longitudinal cross-sectional view with a cross-sectional plane that is parallel to the longitudinal axis of the plate 1 or parallel to the direction of movement 7 when traveling straight ahead. 【0420】 The plate 1 comprises a first side 2 and a second side 3. As can be seen in particular in FIG. 35, wheels 4, 5 are arranged on the second side 3. The plate 1 comprises, on each of its first side 2 and its second side 3, an upwardly and downwardly facing groove 34, the upwardly facing groove 34 being engageable by a downwardly facing tongue 55 of the seating / retaining element 8. The seating / retaining element 8 is attached to the plate 1 by a releasable tongue-and-groove connection. Preferably, the tongue-and-groove connection is biased by inserting the tongue 55 into the groove 34. This bias prevents the release of the tongue-and-groove connection, since for the release an existing tongue-and-groove connection must be overcome. 【0421】 The bias may be caused by the tongue 55 having a greater width than the groove 34 (as can be seen from Figs. 34 and 35 in the image plane) such that the tongue 55 is inserted into the groove 34 while deforming the tongue 55 and / or the groove. Preferably, the tongue 55 and / or the groove 34 are made from a deformable material. The deformation of the tongue 55 and / or the groove 34 when inserting the tongue 55 into the groove 34 creates a frictional force on the contact surface between the tongue 55 and the groove 34, which inhibits the release of the connection. 【0422】 The seating / retaining element 8 comprises a retaining device 11 and, on its upwardly facing side, a seating means 9 (covered by the retaining device in FIG. 34). The retaining device 11 comprises a transverse rod 60 and, on at least one side, a longitudinal rod 61. The transverse rod 60 is centrally located at the upper end of the longitudinal rod 61, whereby the transverse rod 60 and the longitudinal rod 61 form a T-shape. 【0423】 Further advantageous details of this embodiment of the invention can be seen in FIG. 35, the details of which are described below. 【0424】 The front wheels 4 are implemented as settable wheels. The wheels can be set around a steering axis 56, which extends longitudinally as an example in FIG. 35. A child riding on the vehicle of the invention may set the front wheels 4 by pushing the plate 1 in a certain direction. The rear wheels 5 are not implemented as steerable / settable. The front wheels 4 and the rear wheels 5 are arranged in wheel cases 35, 37, respectively. Each wheel case 35, 37 is inserted into the second side surface 3 of the plate 1, preferably via a recess, in the case of a wheel case with a circular cross section via a hole. The implementation shown in FIG. 35 implements the wheel cases 35, 37 conically in their longitudinal extension. The wheel cases 35, 37 are preferably press-fitted into correspondingly implemented holes in the plate 1. 【0425】 The first side 2 has sliding surfaces 30,31. 【0426】 The plate 1 is provided with a recess 16 on the first side 2 and on the second side 3 , which recess 16 defines a storage space 15 . 【0427】 The retaining device 11 is connected to the seating / retaining element 8 via a latch connection. The retaining device 11 is provided with a radially extending hole in the region of the lower end of the longitudinal rod 61. A pin-shaped element of the spring element 59 is inserted through the hole in the longitudinal part 61 and through the hole in the pipe piece 58. In the embodiment shown in FIG. 35, the spring element 59 is implemented as a leaf spring, which is supported on the lateral inner surface of the longitudinal rod 61 opposite the hole. In the inserted position of the retaining element 11, the axes of the holes in the pipe piece 58 and in the longitudinal rod 61 are oriented in the same direction. 【0428】 For this purpose, a receiving plate 57 is inserted into a recess in the seating / retaining element 8. The receiving plate 57 is provided with a pipe piece 58 into which a longitudinal rod 61 of the retaining device 11 is inserted. 【0429】 The receiving plate 57 causes a distribution of the forces acting between the holding device 11 and the seating / holding element 8. This is particularly advantageous when the seating / holding element 8 is made from a foam material.
