Description

Technical Field

[0001] The present invention relates to a snow sliding device for sliding on snow, including a plate-shaped or board-shaped base body that defines a longitudinal axis and has an upper side and a lower side, wherein the base body has a sliding surface for sliding on snow on the lower side. Background Art

[0002] Such snow sliding devices are basically known in the prior art in various configurations, such as skis, sleds or snowboards, and are continuously improved in order to provide the user with the best possible sliding characteristics. Improving the sliding characteristics of the corresponding snow sliding devices in turn forms the basis for performing simple and / or difficult actions (such as turning, jumping, rolling, etc.), depending on the user's skill level.

[0003] Although there are various snow sliding devices that basically meet the needs of inexperienced and experienced users, in order to further enhance the sliding experience of inexperienced and experienced users, for example, in performing certain sliding actions, further improvements in sliding characteristics are still required. Summary of the Invention

[0004] Based on this, the object of the present invention is to provide an improved snow sliding device for sliding on snow.

[0005] This object is achieved by the snow sliding device according to independent claim 1, and the dependent claims relate to possible embodiments of the snow sliding device according to independent claim 1.

[0006] The first aspect of the present invention relates to a snow sliding device for sliding on snow. Thus, the snow sliding device is basically configured as a device that enables the user to slide on snow in a controllable manner at least through appropriate practice. When used as intended, the user usually stands on the snow sliding device with at least one leg; for this purpose, as described in more detail below, the snow sliding device may have at least one fastening interface for a connecting member, which is configured to fasten a boot, that is, for example, a ski boot or a sled boot, to the snow sliding device.

[0007] Specific embodiments of the snow sliding device described herein are skis, sleds or snowboards; thus, the snow sliding device described herein may be configured as, for example, skis, sleds or snowboards.

[0008] The snow sliding device includes a plate-shaped or slab-shaped base body, which has an upper side and a lower side, and the base body defines a longitudinal axis or direction and a transverse axis or direction. The base body can also be referred to or regarded as a base plate. The base body can have a core or core structure made of a single layer or multiple layers, optionally a sandwich-like core material, or a single layer or multiple layers, optionally a sandwich-like core material structure; the corresponding core material can be or include, for example, wood, plastic, metal, or composite materials, such as fiber composite materials, and the corresponding core material structure can be or include, for example, a material structure including wood, plastic, metal, or composite materials, such as a material structure composed of fiber composite materials.

[0009] On the lower side of the base body, at least partially, especially completely, a sliding surface or surface for sliding on snow is arranged or formed, sometimes also called the "base". Therefore, the lower side of the base body is at least partially, especially completely provided with a sliding surface or base for sliding on snow. The corresponding sliding surface or the corresponding riding surface can be made of, for example, graphite, plastic (especially polyethylene-based plastic), or metal, or include at least one of the above materials.

[0010] At least one structure body is arranged on the upper side of the base body. The at least one structure body includes at least one first elastic region having elastic resilience characteristics, and the first elastic region is formed by at least one first bending part (longitudinal bending part) extending in the longitudinal direction of the base body. Therefore, the snow sliding device has a structure with a corresponding base body, on the upper side of which is arranged at least one separated or independent structure body, which is formed by at least one first elastic region having elastic resilience characteristics, or includes such an elastic region, and the at least one first elastic region is formed by at least one first bending part extending in the longitudinal direction of the base body. Therefore, the structure of the snow sliding device provides at least one structure body arranged on the base body, that is, on the upper side of the base body, and the structure body includes at least one first elastic region having elastic resilience characteristics. Therefore, when a corresponding load or force is applied, the first elastic region is elastically resilient, and the first elastic region is formed by at least one first bending part extending in the longitudinal direction of the base body.

[0011] The at least one structure body, that is, especially the at least one first elastic region, due to its elastic resilience characteristics, can also be referred to or regarded as a first elastic body.

[0012] The at least one first bending part is usually a convex bending part; therefore, at least because the first elastic region is formed by at least one first bending part, the at least one structure body has an outwardly curved surface, especially outwardly curved with respect to the upper side of the base body; therefore, at least in terms of the maximum height extension, the snow sliding device is higher than traditional snow sliding devices.

[0013] In principle, the at least one structure body can be formed of the same material or the same material structure as the base body, that is, in particular, the same as the core or the core structure of the base body. Therefore, the difference from the base body lies particularly in its geometric configuration, that is, in particular, at least one first bending portion. Alternatively, the at least one structure body can be formed of a material different from the base body or a material structure different from the base body, that is, in particular, different from the core or the core structure of the base body. Therefore, the difference from the base body lies not only in its geometric configuration, that is, in particular, at least one first bending portion, but also in its "material quality".

[0014] Conveniently, the at least one structure body, that is, in particular, at least one first elastic region, is formed of an elastic resilient material or an elastic resilient material structure, in particular a multi-layer elastic resilient material structure. Specifically, the at least one structure body, that is, in particular, at least one first elastic region, can be formed of, for example, wood, plastic, metal or composite materials, such as fiber composite materials; configurations including single-layer or multi-layer material structures are also conceivable, and the single-layer or multi-layer material structures include wood, plastic, metal or composite materials, such as fiber composite materials.

[0015] The at least one first bending portion forming the at least one first elastic region of the at least one structure body is particularly characterized by a radius extending along the longitudinal direction of the base body, particularly a radius not present in the base body. Therefore, the at least one structure body is in principle different from the base body, particularly in terms of the radius. The radius can, for example, be in the range between 1750 mm and 1950 mm, particularly in the range between 1800 mm and 1900 mm. Tests have shown that in a design favorable for women, the radius is between 1825 mm and 1875 mm, particularly approximately 1855 mm, and in a design favorable for men, the radius is between 1875 mm and 1915 mm, particularly approximately 1895 mm.

[0016] The at least one structure body can, for example, be configured as a web. Specifically, the at least one structure body can, for example, be formed of at least one single-layer or multi-layer plate having a corresponding first bending portion extending in the longitudinal direction of the base body and thus having a corresponding first elastic region, or be formed of at least one single-layer or multi-layer plate having a corresponding first bending portion extending in the longitudinal direction of the base body and thus having a corresponding first elastic region. Therefore, the at least one structure body can be formed of a plate that at least partially, particularly mainly, and if necessary completely, has a bending portion or a protrusion extending in the longitudinal direction of the base body and thus has a plate-like or plate-shaped geometry, or be formed of a plate having a bending portion or a protrusion extending in the longitudinal direction of the base body and thus having a plate-like or plate-shaped geometry.

[0017] Regardless of the specific geometry of the at least one structure or the first elastic region, the structure can be attached or fastened to the substrate, specifically to the upper side of the substrate, via one or more fastening points or regions, in particular via one or more first fastening points or regions and via one or more second fastening points or regions, as follows.

[0018] The configuration of the at least one structure with several corresponding plates or sheets is also conceivable, for example arranged adjacent, opposite and / or laminated. Thus, the at least one structure can also have a plurality of corresponding plates or sheets, which are arranged adjacent, opposite and / or laminated, possibly stacked, in particular in order to specifically influence its structural properties, namely in particular its elasticity and stiffness.

[0019] However, the snow sliding device is characterized not only by the at least one structure arranged on the upper side of the substrate, which has at least one first elastic region formed by at least one first bending portion extending in the longitudinal direction of the substrate and having elastic resilience properties, but also by the fact that the substrate has at least one second elastic region formed by at least one second bending portion extending in the transverse direction of the substrate and having elastic resilience properties. Thus, the substrate also includes at least one elastic region (second elastic region) formed by at least one bending portion (second bending portion) and having elastic resilience properties, wherein, compared with the at least one first bending portion, the at least one second bending portion does not extend in the longitudinal extension or longitudinal direction of the substrate, but in the transverse extension or transverse direction of the substrate. Thus, the extending directions of the at least one first bending portion of the structure and the at least one second bending portion of the substrate are orthogonal to each other, which imparts special structural properties to the snow sliding device as a whole, namely in particular elastic resilience properties.

[0020] By providing at least one corresponding structure on the upper side of the base body and by providing at least one second elastic region on a part of the base body, the structural properties, namely in particular the elastic resilience properties and the stiffness, can be significantly influenced, thereby influencing the gliding properties or gliding performance of the sliding device, for example when the sliding device can be given a certain elasticity, in particular in a direction perpendicular to the upper side of the base body, and the stiffness, in particular in the direction of the longitudinal and / or transverse axis of the base body. The elasticity and stiffness achievable by means of at least one first bend on the structure part and at least one second bend on the base body part bring various advantages for inexperienced and experienced users alike. In order to synergistically achieve the special performance of the snow sliding device, it is crucial that at least one first bend on the structure part and the first elastic region formed thereby match at least one second bend on the base body part and the second elastic region formed thereby, and vice versa. Therefore, the geometric construction characteristics of at least one first bend on the structure part and the first elastic region formed thereby are selected taking into account the geometric construction characteristics of at least one second bend and the second elastic region formed thereby, and vice versa, so as to synergistically achieve the special structural properties of the snow sliding device, namely in particular the special elastic resilience properties and the special stiffness.

[0021] Therefore, the final structural properties of the snow sliding device are produced by the combination of the geometric and structural properties of the base body and at least one structure arranged on the upper side of the base body. Thus, the construction of the snow sliding device 10 with at least one structure arranged on the upper side of the base body, compared to a snow sliding device with a conventional construction, shows significantly improved gliding properties in terms of the achievable structural properties (as described above, in particular the special elasticity and stiffness, and thus the special bending or torsional properties in the longitudinal and / or transverse direction of the base body), and thus in terms of the gliding properties of the snow sliding device formed thereby. The improved gliding properties of the snow sliding device in turn have a positive impact on the execution of certain gliding maneuvers; specifically, for example, the increased elastic resilience properties can improve jumping and landing. Therefore, the snow sliding device can, for example, have a stronger "pop" and / or "flexibility" than a conventional snow sliding device; in any case, the "pop" and / or "flexibility" of the snow sliding device (which particularly applies to snowboards) is especially influenced by the interaction of the base body equipped with the second elastic region and at least one structure arranged on the upper side of the base body and equipped with the first elastic region, i.e., the first elastic region and the second elastic region are configured to match each other.

[0022] In addition to the combination of the structural properties of the base body and of each of the at least one structure, for example the specific dimensions of the at least one structure (in particular relative to the dimensions of the base body), the shape of the at least one structure, the orientation and / or position of the at least one structure relative to the base body, the number, dimensions and arrangement of the contact surfaces on the base body with the at least one structure, are also important for the final structural performance and the final handling performance of the snow sliding device. Thus, the construction of the described snow sliding device is also such that the final structural properties and the final sliding properties of the snow sliding device are influenced not only in particular by the respective structural properties, but also by other aspects, such as in particular the aforementioned aspects.

[0023] As shown below, during the intended use, the user generally does not stand on the base body, but on the at least one structure. Thus, the construction of the snow sliding device also allows the user to stand higher than in a conventional construction, which can also have a positive influence on the sliding properties.

[0024] In a particular embodiment, the interaction of a base body having at least one second elastic region and a structure having at least one first elastic region and arranged or attached on the upper side of the base body can achieve the effect that the snow sliding device can have a special torsion or winding behavior; for example, the special torsion or winding behavior of the snow sliding device can enable it to twist up to 45° about or around the longitudinal axis of the base body. The at least one structure can act as an additional lever, in particular when performing certain maneuvers, such as turning, jibbing, jumping, grinding, etc. This can be due to, for example, the construction of the described snow sliding device being such that the inclination during sliding can be compensated, for example, in a way that allows for a "lever return" to the initial state. As described above, since the user generally does not stand on the base body, but on the elevated at least one structure, the turn control is also made easier or supported, enabling a turn or a corresponding steering to be initiated with less force; thus, the construction of the snow sliding device can include a kind of "power steering", which makes it easier for inexperienced users to learn and thus enhances their sliding experience.

[0025] Overall, there is an improved snow sliding system for sliding on snow.

[0026] The at least one structure, in particular at least one first elastic region, generally has elastic recovery characteristics with respect to forces directed at or acting on the upper side of the substrate, in particular gravity. The elastic recovery characteristics are generally produced by at least one first bending portion. Therefore, the first elastic region formed by at least one first bending portion acts like a leaf spring or imparts leaf spring characteristics to the structure. Thus, the elastic resilience characteristics of the at least one structure, i.e., in particular at least one first elastic region, can be adjusted not only by the elastic resilience characteristics of the material forming the at least one structure or the material structure forming the at least one structure, but also in particular by the specific geometric configuration of at least one first bending portion, i.e., in particular the radius.

[0027] In a similar manner, at least one second elastic region can have elastic resilience recovery characteristics with respect to forces directed at or acting on the upper side of the substrate, in particular gravity. The elastic resilience characteristics are generally produced by at least one second bending portion. Therefore, the second elastic region formed by at least one second bending portion can also act like a leaf spring or impart leaf spring characteristics to the substrate. Thus, the elastic resilience characteristics of at least one second elastic region can be adjusted not only by the elastic resilience characteristics of the material forming the substrate or the material structure forming the substrate, but also particularly by the specific geometric configuration of at least one second bending portion, i.e., in particular the radius.

[0028] A free space is generally formed between the upper side of the substrate and the at least one structure, in particular between the upper side of the substrate and at least one elastic region formed by at least one first bending portion. The free space is curved in the longitudinal direction of the substrate, in particular arch-shaped or arch-like when viewed in the longitudinal direction, and may be dome-shaped or dome-like when viewed from a three-dimensional perspective. The dimensions of the free space, i.e., in particular the maximum distance of the free space from the upper side of the substrate or the maximum height of the free space defined by the dimensions of at least one first bending portion, may also affect the sliding performance of the snow sliding device, as these may affect, for example, the shock absorption characteristics or shock absorption performance of at least one structure.

[0029] Specifically, the free space can, for example, have a maximum distance or maximum height relative to the upper side of the base body of 10 cm, particularly 9 cm, further particularly 8 cm, further particularly 7 cm, further particularly 6 cm, further particularly 5 cm, further particularly 4 cm, further particularly 3 cm, further particularly 2 cm, further particularly 1 cm. As can be seen from the following, the maximum distance or maximum height of the free space can vary, particularly under the corresponding loads, for example, particularly by changing the arrangement of one or more front first attachment points or areas of the structure on the upper side of the base body relative to one or more rear first attachment points or areas, or vice versa. If necessary, this can also be supported by a floating attachment or mounting of at least one structure on the base body, which will be described in more detail below.

[0030] The dimension of at least one structure or at least one first elastic region in the longitudinal direction of the snow sliding device, i.e., its longitudinal extension, is generally selected according to the dimension of the base body in the longitudinal direction, i.e., its longitudinal extension. The dimension of at least one structure or at least one first elastic region in the longitudinal direction of the snow sliding device, i.e., its longitudinal length, is generally smaller than the dimension of the base body in the longitudinal direction, i.e., its longitudinal length; thus, at least one structure or at least one first elastic region is generally shorter than the base body, particularly with respect to the corresponding maximum longitudinal length.

[0031] For example, the at least one structure can have a maximum length dimension that is at least 15%, particularly at least 20%, further particularly at least 25%, particularly at least 30%, further particularly at least 35%, further particularly at least 40%, further particularly at least 45%, further particularly at least 50%, further particularly at least 55%, further particularly at least 60%, further particularly at least 65%, further particularly at least 70%, further particularly at least 75%, further particularly at least 80%, further particularly at least 85%, further particularly at least 90%, further particularly at least 95% of the maximum length dimension of the base body. The selection of the maximum length dimension of the at least one structure and / or the degree to which the base body is covered by the at least one structure also provides a measure, particularly for influencing the final structural characteristics of the snow sliding device. Of course, the maximum length dimension of the at least one structure can vary according to the specific design of the sliding device; when the snow sliding device is designed as a sled, the length dimension of the at least one structure should be at least 15 cm, for example, in order to be able to attach the sled connection as expected.

[0032] Regarding the arrangement of at least one structure on the upper side of the base body, in principle, at least one structure can be arranged in any area of the upper side of the base body. The selection of the arrangement position of at least one structure on the upper side of the base body, especially in combination with the specific length dimension of the at least one structure, also provides a measure for especially influencing the final structural characteristics of the snow sliding device.

[0033] In the longitudinal direction, the base body can include a first base body part having a first free end, a second base body part having a second free end, and a third base body part arranged between the first base body part and the second base body part. The third base body part can, for example, occupy at least 25%, especially at least 30%, further especially at least 35%, further especially at least 40%, further especially at least 45%, further especially at least 50%, further especially at least 55%, further especially at least 60%, further especially at least 65%, further especially at least 70%, further especially at least 75%, further especially at least 80%, further especially at least 85%, further especially at least 90%, further especially at least 95% of the maximum longitudinal dimension of the base body. The at least one structure can be arranged inside or above the third base body part, and the at least one structure can at least partially, especially mainly, and even completely cover the third base body part.

[0034] This also applies to the width or lateral extension of at least one structure or at least one first elastic region in the width or lateral direction of the snow sliding device, that is, in the direction extending transversely to the longitudinal direction of the snow sliding device. Therefore, the dimension of at least one structure or at least one first elastic region in the width or lateral direction, that is, its width or lateral extension, is usually selected according to the dimension of the base body in the width or lateral direction, that is, its width or lateral extension. The dimension of at least one structure or at least one first elastic region in the width or lateral direction of the snow sliding device is usually smaller than the dimension of the base body in the width or lateral direction, that is, its width or lateral extension; thus, at least one structure or at least one first elastic region is usually narrower than the base body, especially with respect to the corresponding maximum width or lateral extension.

[0035] The dimension of at least one second elastic region in the width or transverse direction, i.e., its width or transverse extension, can also be selected according to the dimension of the base body in the width or transverse direction, i.e., its width or transverse extension. The dimension of at least one second elastic region in the width or transverse direction of the snow sliding device can correspond to the dimension of the base body in the width or transverse direction, i.e., its width or transverse extension. However, it is also conceivable that the dimension of at least one second elastic region in the width or transverse direction of the snow sliding device is smaller than the dimension of the base body in the width or transverse direction, i.e., its width or transverse extension; thus, at least the second elastic region can be narrower than the base body, especially with respect to the corresponding maximum width or transverse extension.

[0036] As described above, at least one structure or at least one first elastic region can have a geometry defined by at least one length dimension and at least one width or transverse dimension. The width or transverse dimension of at least one structure or at least one first elastic region can be constant or variable along its longitudinal length, i.e., decreasing and / or increasing. This also applies to at least one second elastic region; thus, the width or transverse dimension of at least one second elastic region can be constant or variable along its longitudinal length, i.e., decreasing and / or increasing.

[0037] In principle, at least one structure or at least one first elastic region can have at least one first region and at least one second region. The first region has a first width or transverse dimension extending in the width or transverse direction of the base body, and the second region has a second width or transverse dimension extending in the width or transverse direction of the base body and different from the first width dimension. Thus, at least one structure or at least one first elastic region can have different width or transverse dimensions; the shaping in the width or transverse direction, i.e., the realization of especially different widths or width regions, also represents a measure for especially influencing the structural characteristics of at least one structure and thus the final structural characteristics of the snow sliding device.

[0038] Specifically, at least one structure or at least one first elastic region may have at least one first region having a first width or transverse dimension extending in the width or transverse direction of the base; at least one second region, which may also be referred to as a connecting web or intermediate web and which has a second width or transverse dimension extending in the width or transverse direction of the base and smaller than the first width or transverse dimension; and a third region having a third width or transverse dimension extending in the width or transverse direction of the base and smaller than the first width or transverse dimension. The width or transverse dimensions of the first region and the third region may be the same or different. At least one second region may be arranged or formed between the first region and the third region in the direction of the longitudinal axis of the base. Thus, at least one structure may have at least one waist due to three independent, possibly different widths or transverse dimensions; the realization of the corresponding at least one waist and its specific dimensions or shape also represents a measure for particularly influencing the structural properties of the structure and thus the final structural properties of the snow sliding device. This applies in particular to the design of the snow sliding device as a ski or sled.

[0039] In a corresponding embodiment of at least one structure having three regions, at least one first elastic region may be formed by or include the at least one second region. Thus, at least one second region may be convexly curved. Thus, at least one first bend may be formed by the at least one second region. Conversely, the corresponding first region and third region may be flat. The respective first region and third region may form first and second support or force-introducing regions or corresponding support surfaces, through which at least one structure is placed on the upper side of the base and through which the forces acting on at least one structure are introduced into the base during use of the snow sliding device.

[0040] In principle, at least one second elastic region may also have at least one first region having a first width or transverse dimension extending in the width or transverse direction of the base, and at least one second region having a second width or transverse dimension extending in the width or transverse direction of the base and different from the first width dimension. Thus, the at least one second elastic region may have different widths or transverse dimensions; the shaping in the width or transverse direction, i.e., in particular the realization of different widths or width regions, also represents a measure for particularly influencing the structural properties of the base and thus the structural properties of the snow sliding device.

[0041] Specifically, the at least one second elastic region may have at least one first region having a first width or lateral dimension extending in the width or lateral direction of the base body; at least one second region, which may also be referred to as a connecting or intermediate web, and which has a second width or lateral dimension extending in the width or lateral direction of the base body and being smaller than the first width or lateral dimension; and a third region having a third width or lateral dimension extending in the width or lateral direction of the base body and being smaller than the first width or lateral dimension. The width or lateral dimensions of the first region and the third region may be the same or different. The at least one second region may be arranged or formed between the first region and the third region in the direction of the longitudinal axis of the base body. Thus, the base body may have at least one waist due to three independent, possibly different widths or lateral dimensions; the realization of the corresponding at least one waist and its specific dimensions or shape also represents a measure for specifically influencing the structural properties of the base body and thus the final structural properties of the snow sliding device. This also applies in particular to the design of snow sliding devices such as skis or sleds.

[0042] At this point, it should generally be noted that the at least one structural body may be directly provided on the upper side of the base body by means of a corresponding support or force - applying region or a corresponding support surface; however, this is not absolutely necessary, since one or more spacers, for example strip - shaped or ribbon - shaped, may be arranged or formed between the at least one structural body and the upper side of the base body such that the at least one structural body is not directly provided on the upper side of the base body, but is provided on one or more corresponding spacer elements, which are directly provided on the upper side of the base body. The final structural properties of the snow sliding device are also particularly influenced by the number, dimensions, arrangement and structural properties of the spacer elements. The height and / or angular position of the user relative to the upper side of the base body is also influenced by the dimensions of one or more spacer elements in the height direction (i.e., in a direction perpendicular to the upper side of the base body). Thus, the corresponding spacer elements may have a height of, for example, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm or more. The corresponding spacer elements may be formed, for example, of an elastic material or an elastic material structure, which also influences the elastic rebound characteristics of the snow sliding device. Thus, the corresponding spacer elements may be made of or composed of, for example, an elastomeric material; damping characteristics may also be generated or influenced in this way, for example for improving the landing performance after a jump.

[0043] It is also conceivable that at least one structural body has a plurality of second regions, each second region being separated from each other by at least one gap. One, several or all of the second regions may be arranged parallel to the longitudinal axis of the base body. Alternatively or additionally, one, several or all of the second regions may be arranged at an angle to the longitudinal axis of the base body. At least two of the several second regions may be arranged parallel to each other. At least two of the plurality of second regions may have the same or different dimensions in the longitudinal and / or transverse directions. Regardless of their orientation and / or position or their dimensions, at least one elastic region may be formed by or include a plurality of second regions that are separated from each other by at least one gap space. Thus, the number, orientation and / or position of the respective second regions, in particular relative to the longitudinal axis of the base body and / or relative to each other, and the dimensions of the respective second regions also provide a measure for particularly influencing the structural properties of the structural body and thus the final structural properties of the snow sliding device. This also applies in particular to the design of snow sliding devices such as skis or sleds.

[0044] In addition to at least one first bend extending in the longitudinal direction of the base body as described above, at least one first elastic region may also have at least one additional bend (transverse bend) extending in the width or transverse direction of the base body. At least with respect to the second region, the at least one structural body may be a dome-shaped or domed member; thus, at least due to the bends in the longitudinal and transverse directions, the at least one first elastic region may be dome-shaped or domed. By shaping at least one first elastic region to have at least one first bend extending in the longitudinal direction of the base body, at least one second bend extending in the width or transverse direction of the base body, and the three-dimensional shape of at least one resulting structural body, another measure is provided for particularly influencing the structural properties of the structural body and thus the final structural properties of the snow sliding device.

[0045] The geometric parameters of the first bend and the other bend of at least one first elastic region, i.e., in particular their respective radii, may be the same or different; the specific geometric parameters of the respective first bend and the other bend also provide a measure for particularly influencing the structural properties of at least one structural body and thus the final structural properties of the snow sliding device.

[0046] In addition to at least one second bending portion extending in the transverse direction of the substrate as described above, at least one second elastic region may also have at least one additional bending portion (longitudinal bending portion) extending in the longitudinal direction of the substrate. At least with respect to the second region, at least one second elastic region may be a dome-shaped or domed structure; thus, at least due to the bending portions in the longitudinal and transverse directions, the at least one second elastic region may be a dome-shaped or domed structure. By shaping the second elastic region to have at least one first bending portion extending in the longitudinal direction of the substrate and at least one second bending portion extending in the width or transverse direction of the substrate and the three-dimensional shape of the at least second elastic region thus formed, another measure is provided in order to particularly influence the structural properties of the structure and thus the final structural properties of the snow sliding device.

[0047] The geometric parameters of the first bending portion and the other bending portion of the at least one second elastic region, i.e., in particular their respective radii, may be the same or different; the specific geometric parameters of the respective first bending portion and the other bending portion also provide a measure for particularly influencing the structural properties of the substrate and thus the final structural properties of the snow sliding device.

[0048] As described above, the at least one structure is generally fastened to the substrate, i.e., in particular to the upper side of the substrate. Thus, the at least one structure may have at least one first fastening interface for fastening the at least one structure to the substrate. The corresponding first fastening interface may be, for example, a form-fitting and / or force-fitting and / or material-fitting fastening interface such that the at least one structure can be fastened to the substrate using a form-fitting and / or force-fitting and / or material-fitting fastening method. Positive and / or non-positive fastening types may in particular be clamping, screwing or tensioning or latching fastening; thus, the corresponding fastening interface may be, for example, a clamping, screwing or tensioning or latching interface, so that, for example, an opening that can be at least partially penetrated by a screw or bolt may be considered. Material-locking fastening types may in particular be adhesive or welding fastening; thus, the corresponding fastening interface may be an adhesive or welding interface, so that, for example, an adhesive or welding surface may be considered.

[0049] In particular, for form-fitting and / or force-fitting fastening types, they enable at least one structural body to be fastened to the base body in a (destructive or non-destructive) detachable manner. Thus, the structural body or at least one structural body can be attached to the base body in a replaceable manner, which in turn opens up the possibility of providing the snow sliding device with different structural characteristics by replacing the first structural body with a second structural body that is (e.g., geometrically and structurally) different. In this way, for example, the same base body can be adapted to users with different sliding abilities and / or different sliding situations. For example, for a sliding situation where multiple jumps must be completed, such as in a U-shaped track, the structural body 30 is advantageous because of its structural characteristics and the way it is attached to the upper side 21 of the base body 20, which supports jumping and landing. While in a sliding situation where multiple turns must be completed, such as in snowboard cross, the structural body 30 is advantageous because of its structural characteristics and the way it is attached to the upper side 21 of the base body 20, which supports turning.

[0050] Specifically, the at least one structural body can particularly have at least one front first fastening interface for fastening the at least one structural body to the base body, the front first fastening interface being arranged or formed in the region of the first or front structural body part facing the first free end of the base body, and at least one rear first fastening interface for fastening the at least one structural body to the base body, the rear first fastening interface being arranged or formed in the region of the second or rear structural body part facing the second free end of the base body.

[0051] The at least one front first fastening interface enables the fastening of the at least one structural body, which is movable in at least one degree of freedom in a movement plane arranged parallel to the upper side of the base body. Thus, the so-called floating attachment or mounting of at least one structural body on the upper side of the base body can be achieved through the at least one front first fastening interface, which in turn represents a measure for particularly influencing the sliding characteristics of the snow sliding device. Specifically, turning can be influenced in this way, for example, by providing the user with additional degrees of freedom to introduce and / or absorb forces, such as when making a turn. Alternatively or additionally, the elastic rebound or recovery characteristics of at least one structural body can be improved, thereby improving, for example, jumping or landing performance, so as to introduce and / or absorb forces, such as when making a jump.

[0052] Alternatively or additionally, at least one rear first fastening interface can enable fastening of the at least one structure that is movable in at least one degree of freedom of movement in a movement plane arranged parallel to the upper side of the base body. Thus, at least one rear first fastening interface can also be used to enable so-called floating fastening or mounting of the at least one structure on the upper side of the base body, which is also a measure that particularly affects the sliding characteristics of the snow sliding device. For example, the turning can also be affected in such a way that the user can obtain an additional degree of freedom in order to introduce and / or absorb forces when turning, for example. Alternatively or additionally, the elastic resilience or recovery characteristics of the at least one structure can be improved, thereby improving, for example, the jumping or landing performance in order to introduce and / or absorb forces when jumping, for example.

[0053] According to a specific exemplary embodiment, only at least one rear first fastening interface (optionally, all rear first fastening interfaces) can enable fastening of the at least one structure that is movable in at least one degree of freedom of movement in a movement plane arranged parallel to the upper side of the base body, while at least one front first fastening interface (optionally, all front first fastening interfaces) is fastened at a fixed position of the base body and is thus immovable in at least one degree of freedom of movement in a movement plane arranged parallel to the upper side of the base body. In the corresponding arrangement, at least one rear first fastening interface is thus also mounted movably relative to at least one front first fastening interface. A configuration contrary to this is also conceivable.

[0054] Specifically, at least one front first fastening interface and / or at least one rear fastening interface can, for example, enable the at least one structure to be fastened to the base body in at least one translational degree of freedom along a translation axis that is oriented in the longitudinal direction of the base body or transversely to the longitudinal direction of the base body. At least one front first fastening interface and / or at least one rear first fastening interface can be displaced relative to the base body along the translation axis, which is thus oriented in the longitudinal direction of the base body or transversely to the longitudinal direction of the base body. This can be achieved, for example, by guide means arranged or formed on and / or in the base body and / or the at least one structure; the corresponding guide means can be formed as, for example, guide grooves in which a guide bolt, for example, serving as a fastening element, is installed in order to engage therein. The corresponding guide grooves can be arranged or formed, for example, in a straight or curved manner, in a direction parallel to the longitudinal and / or transverse axis of the base body or at an angle to the longitudinal and / or transverse axis, that is, in particular, at an angle to the longitudinal and / or transverse axis, on or in the base body or the at least one structure.

[0055] Alternatively or additionally, at least one front first fastening interface and / or at least one rear first fastening interface can fasten at least one structure to or on a substrate such that the structure is movable in at least one rotational degree of freedom about a rotation axis oriented perpendicular to the plane of motion. Thus, at least one front first fastening interface and / or at least one rear first fastening interface can pivot relative to the substrate about a rotation axis oriented perpendicular to the plane of motion. This can also be achieved, for example, by means of guiding means arranged or formed on and / or in the substrate and / or at least one structure; the corresponding guiding means can in turn be, for example, guiding grooves in which a guiding bolt, for example serving as a fastening element, is installed for engagement therein. The corresponding guiding grooves can be arranged or formed, for example, linearly or curvilinearly, in a direction parallel to the transverse axis of the substrate or at an angle to this transverse axis, i.e., in particular at an angle to this transverse axis, on or in the substrate or at least one structure.

[0056] The at least one front first fastening interface and / or the at least one rear first fastening interface can be specifically arranged or formed, for example, in the region of a part of the structure that forms a flat support on the upper side of the substrate, i.e., for example, in the first region and / or the third region of the structure further mentioned above. In this way, a stable attachment of at least one structure to the substrate can be achieved despite the at least one structure having at least one translational and / or rotational degree of freedom relative to the substrate.

[0057] As mentioned at the beginning, the snow sliding device can have at least one fastening interface for a connecting element (such as a ski connecting element or a sled connecting element) through which a boot (such as a ski boot or a sled boot) can be fastened to the snow sliding device. Specifically, the corresponding fastening interface can be arranged or formed on at least one structure. Thus, in all embodiments, at least one structure can have at least one second fastening interface for fastening a connecting element for the user. Specifically, the at least one structure can have one or more second fastening interfaces for fastening a first connecting element, which are arranged or formed in the region of the first free end (front free end) of the structure part facing the substrate, and one or more second fastening interfaces for fastening a second connecting element, which are arranged or formed in the region of the second free end (rear free end) of the structure part facing the substrate. This applies in particular to the design of skis.

[0058] The corresponding second fastening interface can, for example, be a form-fitting and / or force-fitting fastening interface, such that a form-fitting and / or force-fitting fastening method can be used to fasten the connecting member to at least one structural body. In particular, for positive and / or non-positive fastening types, these can enable the connecting member to be attached to at least one structural body in a detachable (without damage or destruction) manner. The positive-fitting and / or non-positive-fitting fastening types can in particular be clamping, screwing or tensioning or latching fastening; thus, the corresponding fastening interface can be, for example, a clamping, screwing or tensioning or latching interface, such that, for example, an opening that can be at least partially penetrated by a screw or bolt can be considered.

[0059] Another measure that particularly affects the structural properties of at least one structural body and thus the final structural properties of the snow sliding device can be implemented, since at least one structural body has one or more influencing structures, in particular in the form of local strengthening and / or weakening, in at least one direction, in particular in the longitudinal direction and / or the transverse direction of the base body, locally influencing the elastic resilience properties. The corresponding local strengthening can be achieved, for example, by geometric structure parameters, such as (relatively) higher wall thicknesses, material accumulations, strengthening geometries (such as rib geometries), etc. Similarly, the corresponding local weakening can be achieved, for example, by geometric structure parameters, such as (relatively) lower wall thicknesses, material cuts, weakening geometries (such as openings), etc.

[0060] In addition to the at least one structural body, the base body can also be constructed in a specific manner in order to improve the final structural properties of the snow sliding device and thus its sliding properties. For example, the base body can include, in the longitudinal direction, a first base body part having a first free end, a second base body part having a second free end, and a third base body part arranged between the first base body part and the second base body part, wherein the third base body part includes at least a second bending part and thus forms a second elastic region. Thus, the third base body part can have a second elastic region that is formed by at least one second bending part extending in the longitudinal and / or transverse direction of the base body and has elastic, resilient properties. The second elastic region can be formed, for example, by a relatively thin wall thickness of the base body. Specifically, at least one second elastic region of the base body can thus be formed, for example, by a groove-shaped or trough-shaped depression extending specifically in the longitudinal direction of the base body and / or by a protrusion extending in the longitudinal direction of the base body.

[0061] The corresponding depressions and protrusions may have a maximum length dimension that is at least 15%, particularly at least 20%, further particularly at least 25%, particularly at least 30%, further particularly at least 35%, further particularly at least 40%, further particularly at least 45%, further particularly at least 50%, further particularly at least 55%, further particularly at least 60%, further particularly at least 65%, further particularly at least 70%, further particularly at least 75%, further particularly at least 80%, further particularly at least 85%, further particularly at least 90%, further particularly at least 95% of the maximum length dimension of the substrate. By selecting the maximum length dimension of the depressions and / or protrusions, a measure is provided that particularly affects the structural properties of the substrate and thus the final structural properties of the snow sliding device. Of course, the maximum length dimension of the depressions and / or protrusions may vary according to the specific design of the snow sliding device.

[0062] The width or lateral dimension of the depressions and / or protrusions may be constant or variable along their longitudinal or transverse extension, i.e., decreasing and / or increasing, for example. The depth of the depressions and / or the height of the protrusions may also be constant or variable along their longitudinal or transverse extension, i.e., decreasing and / or increasing. Generally speaking, therefore, the corresponding depressions and / or protrusions may have a cross-sectional geometry that is constant or variable in the longitudinal and / or transverse direction.

[0063] The corresponding depressions or protrusions in the substrate are typically formed in the upper side of the substrate. Specifically, due to the fact that the lower side of the substrate is provided with a sliding surface or gliding surface, it can be easily processed, for example, for maintenance and / or repair, just like traditional snow sliding devices.

[0064] The second elastic region or at least one second bending portion forming the second elastic region may be at least partially integrated into the substrate and, if desired, may be fully integrated into the substrate. Specifically, the second elastic region or at least one second bending portion forming the second elastic region may be formed by a core structure of the substrate that has at least one second bending portion extending transversely to the substrate. Thus, the second elastic region may be formed by a core structure of the substrate that is arranged between the upper side and the lower side of the substrate and that has at least one second bending portion extending transversely to the substrate.

[0065] Regarding the type of at least one first bending portion and at least one second bending portion, they may be configured to be in opposite directions. Thus, for example, at least one first elastic region may have at least one convex bending portion extending along the longitudinal direction of the substrate, and at least one second elastic region may have at least one concave bending portion extending along the transverse direction of the substrate. However, a configuration in which at least one first bending portion and at least one second bending portion are of the same type is also conceivable in principle.

[0066] Specifically, therefore, at least one first elastic region may have at least one convex bend extending in the longitudinal direction of the substrate, and at least one second elastic region may be formed by a core structure of the substrate having at least one concave bend extending in the transverse direction of the substrate. Surprisingly, in tests, this configuration of the snow sliding device has been found to have characteristics that are particularly useful in terms of sliding characteristics and performance.

[0067] A second aspect of the present invention relates to a method of manufacturing a snow sliding device according to the first aspect of the present invention. Specifically, the method comprises the steps of: providing a plate-like substrate defining a longitudinal axis and having an upper side and a lower side, the substrate having at least one second elastic region and a sliding surface on the lower side for sliding on snow, the second elastic region being formed by at least one second bend extending in the transverse direction of the substrate and the second elastic region having elastic resilience characteristics; and fastening at least one structural body to the upper side of the substrate, wherein the at least one structural body has at least one elastic region formed by at least one first bend extending in the longitudinal direction of the substrate and the elastic region having elastic resilience characteristics. All descriptions related to the snow sliding device apply to this method and vice versa. Description of the Drawings

[0068] The present invention will now be explained again with reference to the embodiments shown in the drawings:

[0069] Figures 1 - 5 are schematic diagrams of the principle of a snow sliding device according to an exemplary embodiment;

[0070] Figures 6 - 12 are schematic diagrams of the principle of a snow sliding device according to a further embodiment; and

[0071] Figure 13 and Figure 14 are schematic diagrams of the substrate of a snow sliding device according to an exemplary embodiment. Detailed Description of the Invention

[0072] Figures 1 - 5 Schematic diagrams of a snow sliding device 10 according to an exemplary embodiment are shown respectively. The snow sliding device 10 is shown in Figure 1 in a perspective view, in Figure 2 in a top view, and in Figure 3 in a side view. Figure 4 and Figure 5 show Figure 2 magnified views of details IV and V in

[0073] The snow sliding device 10 is configured as a device that enables a user to slide or glide on snow in a controlled manner, at least with appropriate practice. When used as intended, the user typically stands on the snow sliding device 10 with at least one leg; to this end, the snow sliding device 10 may include at least one (second) fastening interface for a connecting member, as will be described in more detail below, which is configured to fasten a boot, such as a ski boot, for example, to the snow sliding device 10.

[0074] In the embodiment shown in the figures, the snow sliding device 10 is configured as a ski; however, the following embodiments are equally applicable to other embodiments of the snow sliding device 10, such as embodiments as a sled or a snowboard.

[0075] The snow sliding device 10 includes a plate-shaped or board-shaped base body 20 that defines a longitudinal axis A1 or longitudinal direction and a transverse axis A2 or transverse direction, and the base body has an upper side 21 and a lower side 22. The base body 20 may also be referred to or regarded as a base plate and may have a core or core structure 28 made of a single layer or multiple layers of optionally sandwich-like core materials, or a single layer or multiple layers of optionally sandwich-like core material structures; the core material may be, for example, wood, plastic, metal, or a composite material, such as a fiber-reinforced composite material, and the core material structure may be, for example, a material structure including wood, plastic, metal, or a composite material, such as a material structure composed of a fiber-reinforced composite material.

[0076] On the lower side 22 of the base body 20, a sliding surface 23 or a surface for sliding or gliding on snow, sometimes also referred to as a "base", is at least partially, particularly completely, arranged or formed. Thus, the lower side 22 of the base body 20 is at least partially, particularly completely, provided with a sliding surface 23 or a gliding surface for sliding on snow. The sliding surface 23 or the gliding surface may be formed, for example, by graphite, plastic (particularly polyethylene-based plastics), or metal, or include at least one of the above materials.

[0077] The structure 30 is arranged on the upper side 21 of the base body 20. In the exemplary embodiment, the structure 30 includes a first elastic region 31 having elasticity, and the first elastic region 31 is formed by a first bending portion 32a (longitudinal bending portion) extending in the longitudinal direction of the base body 20. Thus, the snow sliding device 10 has a configuration with the base body 20, and a separate structure 30 is provided on the upper side of the base body 20. The structure 30 is formed by or has the first elastic region 31 having elastic resilience characteristics. The first elastic region 31 is formed by the first bending portion 32a extending in the longitudinal direction of the base body 20. Therefore, the configuration of the snow sliding device 10 provides a structure 30 arranged on the upper side 21 of the base body 20. The structure 30 includes a first elastic region 31 having elastic resilience characteristics. Thus, when a corresponding load or force is applied, the first elastic region 31 is elastically resilient, and the first elastic region 31 is formed by the first bending portion 32a extending in the longitudinal direction of the base body 20.

[0078] The structure 30, that is, in particular the first elastic region 31, due to its elastic resilience characteristics, can also be referred to or regarded as a first elastic body.

[0079] From Figure 1 and Figure 3 It can be seen that the first bending portion 32a can be a convex bending portion; thus, the structure 30 includes an outwardly curved surface at least because the first elastic region 31 is formed by the first bending portion 32a, in particular outwardly curved with respect to the upper side 21 of the base body 20; thus, at least in terms of the maximum height extension, the snow sliding device 10 is higher than the conventional snow sliding device.

[0080] In principle, the structure 30 can be formed of the same material or the same material structure as the base body 20, that is, in particular the same as the core or core structure of the base body 20. Therefore, the difference from the base body 20 is especially its geometric configuration, that is, in particular the first bending portion 32a. Alternatively, the structure 30 can be formed of a material different from the base body 20 or a material structure different from the base body 20, that is, in particular different from the core or core structure of the base body 20. Therefore, the difference from the base body 20 lies not only in its geometric configuration, that is, in particular the first bending portion 32a, but also in its "material".

[0081] Conveniently, the structure 30, that is, in particular the first elastic region 31, is formed of an elastically resilient material or an elastically resilient material structure, in particular a multi-layer elastically resilient material structure. Specifically, the structure 30, that is, in particular the first elastic region 31, can be formed of, for example, wood, plastic, metal, or a composite material, such as a fiber composite material; a configuration including a single-layer or multi-layer material structure including wood, plastic, metal, or a composite material, such as a fiber composite material, is also possible.

[0082] The first bending portion 32a that forms the first elastic region 31 is particularly characterized by a radius R extending in the longitudinal direction of the base body 20, which does not exist in the base body 20. Therefore, as shown in the figure, the structural body 30 is particularly different from the base body 20 in terms of this radius R. The radius R of the first bending portion 32a can, for example, be in the range between 1750 mm and 1950 mm, particularly in the range between 1800 mm and 1900 mm. In the construction of the snow sliding device 10 for women, the radius R can be in the range between 1825 mm and 1875 mm, particularly approximately 1855 mm, and in the construction of the snow sliding device 10 for men, the radius R is in the range between 1875 mm and 1915 mm, particularly approximately 1895 mm.

[0083] The drawings show that the structural body 30 can in principle be configured, for example, in a mesh or net shape. Specifically, the drawings show that the structural body 30 can be formed by corresponding first bending portions 32a extending in the longitudinal direction of the base body 20, thereby having corresponding first elastic regions 31, single or multi-layer plates, or corresponding single or multi-layer sheets. Therefore, the structural body 30 can be formed by a plate or a corresponding sheet, which at least in some parts, particularly in the main part, optionally completely has curvature or curvation, thereby presenting a curved or bent plate-like or sheet-like or disc-like or stacked or laminated geometric shape.

[0084] A construction of the structural body 30 having a plurality of corresponding plates or sheets, for example arranged adjacent, opposite, and / or laminated, is also conceivable. Therefore, particularly in order to specifically influence its structural properties, namely particularly its elasticity and stiffness, the structural body 30 can also have a plurality of corresponding plates or sheets, which can be arranged in a stacked, adjacent, opposite, and / or laminated manner.

[0085] By providing the structural body 30 on the upper side 21 of the base body 20, the structural properties of the snow sliding device 10 can be significantly influenced, namely particularly elasticity and stiffness, thereby influencing the sliding characteristics or sliding performance. For example, when the snow sliding device 10 can be given a certain elasticity, particularly in the direction perpendicular to the upper side 21 of the base body 20, and stiffness, particularly in the direction of the longitudinal and / or transverse axes of the base body 20. Such elasticity and stiffness that can be achieved or have been achieved by the structural body 30 bring various advantages to both inexperienced and experienced users.

[0086] From Figure 13 and Figure 14 it can be seen that each figure shows the base body 20 of the snow sliding device 10 in a perspective view. However, its structural properties are not only determined by at least one structural body 30 arranged on the upper side 21 of the base body 20 (which is in Figure 13and Figure 14 is not shown) to determine. The structure 30 includes a first elastic region 31 formed by at least one first bending portion 32a and having elastic resilience characteristics. The first bending portion 32a extends along the longitudinal direction of the base body 20. Moreover, the base body 20 includes a second elastic region 27 formed by at least one second bending portion 27a and having elastic resilience characteristics. The second bending portion 27a extends along the transverse direction of the base body 20. Therefore, the base body 20 includes an elastic region 27 (second elastic region) formed by at least one bending portion (second bending portion 27a) and having elastic resilience characteristics. Among them, compared with at least one first bending portion 32a of the first elastic region 31, at least one second bending portion 27a of the second elastic region 27 does not extend along the longitudinal direction or the longitudinal direction of the base body 20, but extends along the transverse direction or the transverse direction of the base body 20. Therefore, the extending directions of at least one first bending portion 32a of the structure 30 and at least one second bending portion 27a of the base body 20 are orthogonal to each other, which endows the snow sliding device with special structural characteristics as a whole, namely, especially elastic resilience characteristics.

[0087] Therefore, the final structural characteristics of the snow sliding device 10 are generated by the combination of the geometric characteristics and structural characteristics of the base body 20 and the structure 30 disposed on the upper side 21 of the base body 20. Therefore, the structure of the snow sliding device 10 with the structure 30 disposed on the upper side 21 of the base body 20, compared with the snow sliding device with a traditional structure, shows significantly improved sliding characteristics in terms of the achievable structural characteristics (as described above, especially special elasticity and stiffness, and thus special bending or torsional characteristics in the longitudinal and / or transverse directions of the base body 20), and in terms of the sliding characteristics of the snow sliding device 10 formed thereby. The improved sliding characteristics of the snow sliding device 10 in turn have a positive impact on the execution of certain sliding actions; specifically, for example, the increased elastic resilience performance improves jumping and landing. Therefore, the snow sliding device 10 can, for example, have stronger "bounce" and / or "flexibility" than traditional snow sliding devices; in any case, the "bounce" and / or "flexibility" of the snow sliding device 10 (which especially applies to snowboards) is particularly affected by the structure 30 disposed on the upper side 21 of the base body 20.

[0088] In addition to the combination of the respective structural characteristics of the base body 20 and the structure body 30, aspects such as, for example, the specific dimensions of the structure body 30 (especially relative to the dimensions of the base body 20), the shape of the structure body 30, the orientation and / or position of the structure body 30 relative to the base body 20, and the number, dimensions, and arrangement of the contact surfaces 33a, 33b are also important for the final structural performance and the final sliding performance of the snow sliding device 10. Therefore, the described construction of the snow sliding device 10 also enables the final structural characteristics and the final sliding characteristics of the snow sliding device 10 to be influenced not only particularly by the corresponding structural characteristics, but also by other aspects, such as especially the aforementioned aspects.

[0089] As can be seen from the following figures, when the snow sliding device 10 is used as intended, the user usually stands on the structure body 30 rather than on the base body 20. Therefore, the construction of the snow sliding device 10 also allows the user to stand higher than in a conventional construction, which may also have a positive impact on the sliding characteristics.

[0090] In a specific embodiment, the interaction between the base body 20 and the structure body 30 arranged or attached to its upper side 21 can achieve the effect that the snow sliding device 10 can have a special twisting or winding behavior; the special twisting or winding behavior of the snow sliding device 10 enables it to twist up to 45° about or around the longitudinal axis of the base body 20. The structure body 30 can act as an additional lever, especially when performing certain actions, such as turning, rocking, jumping, rolling, etc., not only promoting or supporting improved sliding characteristics, but also being able to compensate for possible sliding mistakes, which helps to avoid or at least reduce the number of falls. This may be because, for example, the described construction of the snow sliding device 10 enables the inclination during sliding to be compensated, for example, by means of "lever return" to the initial state. As described above, since the user usually does not stand on the base body 20, but on the elevated structure body 30, the turning control also becomes easier or is supported, enabling a turn or the corresponding steering to be initiated with less force; therefore, the construction of the snow sliding device 10 can include the characteristic of "power steering", which makes it easier for inexperienced users to learn and thus enhances their sliding experience.

[0091] Due to its geometry, the structure 30, especially the first elastic region 31, has an elastic resilience recovery characteristic with respect to forces directed at or acting on the upper side 21 of the base body 20, especially gravity. The elastic recovery characteristic is mainly generated by the first bending portion 32a. Therefore, the first elastic region 31 functions similar to a leaf spring or imparts the characteristics of a leaf spring to the structure 30. Thus, the elastic resilience characteristic of the structure 30, that is, especially the elastic resilience characteristic of the first elastic region 31, can be adjusted not only by the elastic resilience characteristic of the material forming the structure 30 or the material structure forming the structure 30, but also especially by the specific geometric configuration of the first bending portion 32a, that is, especially the radius R.

[0092] In a similar manner, the second elastic region 27 has an elastic recovery characteristic with respect to forces directed at or acting on the upper side of the base body 20, especially gravity. The elastic recovery characteristic is generally generated by at least one second bending portion. Therefore, the second elastic region 27 can also function similar to a leaf spring or impart the characteristics of a leaf spring to the base body 20. Thus, the elastic resilience characteristic of the second elastic region 27 can be adjusted not only by the elastic resilience characteristic of the material forming the base body 20 or the material structure forming the base body 20, but also especially by the specific geometric configuration of at least one second bending portion 27a, that is, especially the radius.

[0093] It can also be seen from the figure that a free space FR is formed between the upper side 21 of the base body 20 and the structure 30, especially between the upper side 21 of the base body 20 and the first elastic region 31 formed by the first bending portion 32a. The free space FR extends in a curved manner in the longitudinal direction of the base body 20, especially in an arch-like or arch-shaped manner, and in any case when observed from the longitudinal direction. When observed from a three-dimensional perspective, the free space FR can be dome-shaped or dome-like. The size of the free space FR, that is, especially the maximum distance of the free space FR from the upper side 21 of the base body 20 or the maximum height h of the free space FR defined by the size of the first bending portion 32a max , may also affect the sliding characteristics of the snow sliding device 10 because these may affect, for example, the damping characteristics or damping performance of the structure 30.

[0094] Specifically, the free space FR can, for example, have a maximum distance or maximum height relative to the upper side 21 of the base body 20 of 10 cm, especially 9 cm, further especially 8 cm, further especially 7 cm, further especially 6 cm, further especially 5 cm, further especially 4 cm, further especially 3 cm, further especially 2 cm, further especially 1 cm. As can be seen from the following, the maximum distance or maximum height h of the free space FR maxIt can vary, especially under corresponding loads, for example by selectively changing the arrangement of one or more front first fastening points 37a or areas of the structure 30 on the upper side 21 of the base 20 relative to one or more rear first fastening points 37b or areas. If necessary, this can also be supported by a floating fastening or mounting of the structure 30 on the base 20, which will be described in more detail below.

[0095] The dimension of the structure 30 or the first elastic region 31 in the longitudinal direction of the snow sliding device 10, i.e., its longitudinal extension, is generally selected according to the dimension of the base 20 in the longitudinal direction, i.e., its longitudinal extension. The dimension of the structure 30 or the first elastic region 31 in the longitudinal direction of the snow sliding device 10, i.e., its longitudinal length, is generally smaller than the dimension of the base 20 in the longitudinal direction, i.e., its longitudinal length; thus, the structure 30 or the first elastic region 31 is generally shorter than the base 20, especially in terms of the corresponding maximum longitudinal length.

[0096] As can be seen Figures 1 - 5 from, the structure 30 can, for example, have a maximum length dimension that is at least 50% of the maximum length dimension of the base 20. The selection of the maximum length dimension of the structure 30 and / or the degree to which the base 20 is covered by the structure 30 can also be used specifically to influence the final structural characteristics of the snow sliding device 10. Of course, the maximum length dimension of the structure 30 can vary according to the specific configuration of the snow sliding device; when the snow sliding device 10 is designed as a sled, the length dimension of the structure 30 should be at least 15 cm, for example, in order to be able to attach the sled connection as expected.

[0097] Regarding the arrangement of the structure 30 on the upper side 21 of the base 20, in principle, the structure 30 can be arranged in any area of the upper side 21 of the base 20. The selection of the arrangement position of the structure 30 on the upper side 21 of the base 20, especially in combination with the specific length dimension of the structure 30, also provides a measure for especially influencing the final structural characteristics of the snow sliding device 10.

[0098] As can be seen Figures 1 - 5 from, the base 20 can include a first base portion 24 having a first free end, a second base portion 25 having a second free end, and a third base portion 26 arranged between the first base portion 24 and the second base portion 25 in the longitudinal direction. The third base portion 26 can, for example, occupy at least 50% of the maximum length dimension of the base 20. In an exemplary embodiment, the structure 30 is exemplarily arranged inside or above the third base portion 26 and at least partially, especially mainly, even completely covers the third base portion 26.

[0099] The same applies to the width or lateral extent of the structure 30 or the first elastic region 31 in the width or lateral direction of the snow slide device 10, i.e., in a direction transverse to the longitudinal direction of the snow slide device 10. Thus, the dimension of the structure 30 or the first elastic region 31 in the width or lateral direction, i.e., its width or lateral extent, is typically selected according to the dimension of the base body 20 in the width or lateral direction, i.e., its width or lateral extent. The dimension of the structure 30 or the first elastic region 31 in the width or lateral direction of the snow slide device 10 is typically smaller than the dimension of the base body 20 in the width or lateral direction, i.e., its width or lateral extent; thus, the structure 30 or the first elastic region 31 is typically narrower than the base body 20, especially with respect to the corresponding maximum width or lateral extent.

[0100] As shown in the figure, the structure 30 can have a geometry defined by at least one length dimension and at least one width or lateral dimension. The width or lateral dimension of the structure 30 can be constant along its longitudinal length or, as shown by way of example in the figure, variable, i.e., decreasing and / or increasing.

[0101] It can also be seen from the figure that the structure 30 can in principle have at least one first region 34 and at least one second region 36, the first region 34 having a first width or lateral dimension extending in the width or lateral direction of the base body 20, and the second region 36 having a second width or lateral dimension different from the first width dimension extending in the width or lateral direction of the base body 20. Thus, the structure 30 can have different width or lateral dimensions; the shaping in the width or lateral direction, i.e., in particular the realization of different widths or width regions, also represents a measure for especially influencing the structural characteristics of the structure 30 and thus the structural characteristics of the snow slide device 10.

[0102] Specifically, the drawing shows that the structure 30 includes a first region 34 having a first width or lateral dimension extending in the width or lateral direction of the base body 20; at least one second region 36, which may also be referred to as a connecting web or intermediate web and which has a second width or lateral dimension extending in the width or lateral direction of the base body 20 and smaller than the first width or lateral dimension; and a third region 35 having a third width or lateral dimension extending in the width or lateral direction of the base body 20 and smaller than the first width or lateral dimension. In an exemplary embodiment, the width or lateral dimensions of the first region 34 and the third region 35 are (substantially) the same, but in principle they may also be different. At least one second region 36 is arranged or formed between the first region 34 and the third region 35 in the direction of the longitudinal axis A1 of the base body 20. Thus, the structure 30 can have a waist due to three independent, possibly different widths or lateral dimensions; the implementation of the corresponding waist and its specific dimensions or shape also represents a measure for particularly influencing the structural properties of the structure 30 and thus the final structural properties of the snow sliding device 10.

[0103] Obviously, in the corresponding embodiment of the structure 30 having three regions 34 - 36, the first elastic region 31 can be formed by or include at least one second region 36. Thus, at least one second region 36 can be convexly curved. Thus, the first bend 32a can be formed by at least one second region 36. On the other hand, the first region 34 and the third region 35 can be flat and form a first support or force introduction region and a second support or force introduction region or corresponding support surfaces 33a, 33b, through which the structure 30 is placed on the upper side 21 of the base body 20 and through which the forces acting on the structure 30 during the use of the snow sliding device 10 are introduced into the base body 20.

[0104] At this point, it should generally be noted that according to Figures 1 - 5 the structure 30 in the exemplary embodiment of Figure 9Example embodiments, which are not absolutely necessary, since between the upper side 21 of the structure 30 and the base body 20, one or more spacer elements 40 (spacers), for example in the form of strips or bands, can be arranged or formed such that the structure 30 is not directly arranged on the upper side 21 of the base body 20, but on one or more corresponding spacer elements 40, which are directly arranged on the upper side 21 of the base body 20. The final structural properties of the snow sliding device 10 are also particularly influenced by the number, size, arrangement and structural properties of the spacer elements 40. The size of one or more spacer elements 40 in the height direction, i.e., in the direction perpendicular to the upper side 21 of the base body 20, can also be used to influence the height and / or angular position of the user relative to the upper side 21 of the base body 20. Thus, the corresponding spacer elements 40 can have a height of, for example, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm or more. The corresponding spacer elements 40 can be formed, for example, from an elastic material or an elastic material structure, which also influences the elastic rebound properties of the snow sliding device 10. Thus, the corresponding spacer elements 40 can be formed or composed of, for example, an elastomeric material; damping properties can also be generated or influenced in this way, for example for improving the landing performance after a jump.

[0105] As described above, the structure 30 is attached to the base body 20, i.e., in particular to the upper side 21 of the base body 20. Thus, the structure 30 can have at least one first fastening interface 37a, 37b for fastening the structure 30 to the base body 20. The corresponding first fastening interfaces 37a, 37b can be, for example, form-fitting and / or force-fitting and / or material-fitting fastening interfaces such that a form-fitting and / or force-fitting and / or material-fitting fastening method can be used to fasten the structure 30 to the base body 20. The form-fitting and / or force-fitting fastening types can specifically be clamping, screwing or tensioning or latching fastening; thus, the corresponding first fastening interfaces 37a, 37b can be, for example, clamping, screwing or tensioning or latching interfaces, so that, for example, openings that can be locally penetrated by screws or bolts can at least be considered. The material-locking fastening type can specifically be adhesive or welding fastening; thus, the corresponding first fastening interfaces 37a, 37b can be adhesive or welding interfaces, so that, for example, adhesive or welding surfaces can be considered.

[0106] In particular, for positive and / or non-positive fastening types, it is suitable for fastening the structure 30 to the base 20, and this fastening can be detachable (without damage or destruction). Therefore, the structure 30 or at least one structure 30 can be attached to the base 20 in a replaceable manner, which in turn opens up the possibility of providing the snow sliding device 10 with different structural characteristics by replacing the first structure 30 with a second structure 30 that is different (for example, in terms of geometry and design). In this way, for example, the same base 20 can be adapted to users with different sliding abilities and / or different sliding situations. For example, for a sliding situation where multiple jumps must be completed, such as in a halfpipe, the structure 30 is advantageous because of its structural characteristics and the way it is attached to the upper side 21 of the base 20 to support jumping and landing. While in a sliding situation where multiple turns must be completed, such as in cross-country skiing, the structure 30 is advantageous because of its structural characteristics and the way it is connected to the upper side 21 of the base 20 to support turning.

[0107] As can be seen from the figure, the structure 30 can have one or more front first fastening interfaces 37a for fastening the structure 30 to the base 20, and this interface is arranged or formed in the region of the first or front structure part facing the first or front free end of the base 20 (see Figure 4 ), and one or more rear first fastening interfaces 37b for fastening the structure 30 to the base 20, and this interface is arranged or formed in the region of the second or rear structure part facing the second or rear free end of the base 20 (see Figure 5 ).

[0108] Referring to Figure 5 , it can be seen that at least one front first fastening interface 37a, that is, the fastening interface 37a shown as elongated, can achieve the fastening of the structure 30, and the structure 30 is movable in at least one degree of freedom of movement in a movement plane arranged parallel to the upper side of the base 20. Through this front first fastening interface 37a, therefore, a so-called floating fastening or mounting of the structure 30 on the upper side 21 of the base 20 can be achieved, which in turn represents a measure for particularly influencing the sliding characteristics of the snow sliding device 10. Specifically, the turning can be influenced in this way, for example, by providing the user with additional degrees of freedom to introduce and / or absorb forces, such as when turning. Alternatively or additionally, for example, the elastic rebound or recovery characteristics of the structure 30 can be improved, thereby improving, for example, the jumping or landing performance, so as to introduce and / or absorb forces, for example, during jumping.

[0109] In an exemplary embodiment, an exemplary combination of two front fastening interfaces 37a with different configurations is particularly shown, wherein the fastening interface 37a directly arranged in the region of the front free end of the structure 30 can in principle achieve a floating fastening or mounting of the structure 30 on the upper side 21 of the base body 20 in each case, while the other two fastening interfaces 37a shown in an annular manner achieve a position-fixed fastening or mounting of the structure 30 on the upper side 21 of the base body 20 in each case.

[0110] It can be seen from Figure 5 that the rear first fastening interface 37b can also achieve the fastening of the structure 30, which is movable in at least one degree of freedom in a movement plane arranged parallel to the upper side 21 of the base body 20. Therefore, the so-called floating fastening or mounting of the structure 30 on the upper side 21 of the base body main body 20 can also be achieved by the rear first fastening interface 37b, which also represents a measure for particularly influencing the sliding performance of the snow sliding device 10. For example, the turning can also be influenced in such a way that the user can obtain an additional degree of freedom in order to introduce and / or absorb forces, for example when turning. Alternatively or additionally, the elastic resilience or recovery characteristics of the structure 30 can be improved, thereby improving, for example, the jumping or landing performance in order to introduce and / or absorb forces, for example when jumping.

[0111] In an exemplary embodiment, an exemplary combination of two rear fastening interfaces 37b with the same configuration is particularly shown, and each rear fastening interface can achieve a floating fastening or mounting of the structure 30 on the upper side 21 of the base body 20.

[0112] In principle, and thus independent of the embodiment shown in the figure, only at least one front or rear first fastening interface 37a, 37b (possibly all front or rear first fastening interfaces 37a, 37b) can achieve the fastening of the structure 30, which is movable in at least one degree of freedom in a movement plane arranged parallel to the upper side 21 of the base body 20, while the remaining front or rear first fastening interfaces 37a, 37b are fastened at fixed positions of the base body 20 and are thus immovable in at least one degree of freedom in a movement plane arranged parallel to the upper side 21 of the base body 20.

[0113] Returning to Figure 4 、 Figure 5In the exemplary embodiment shown, the front and rear first fastening interfaces 37a, 37b for achieving floating fastening or mounting can specifically fasten the structure 30 to or on the base 20, and the structure 30 is movable in terms of translational freedom on a translation axis oriented in the longitudinal direction of the base 20. Thus, the corresponding front and rear first fastening interfaces 37a, 37b, and in any case the rear first fastening interface 37b, can be displaced relative to the base 20 along a translation axis oriented in the longitudinal direction of the base 20. This can be achieved, for example, by arranging or forming guiding means on or in the base 20 and / or the structure 30. As shown in the example in the figure, the guiding means can be configured, for example, as guiding grooves 38a, 38b, and guiding bolts serving as fastening elements 39a, 39b are installed in the guiding grooves 38a, 38b so as to engage therein. The corresponding guiding grooves 38a, 38b can be arranged or formed, for example, in a straight line or a curve (although not shown), in a direction parallel to the longitudinal axis of the base 20 or at an angle to this longitudinal axis (although not shown), that is, especially at an angle to this longitudinal axis, on or in the base 20 or the structure 30.

[0114] Although not shown, the front and rear first fastening interfaces 37a, 37b for achieving floating fastening or mounting can fasten the structure 30 to or on the base 20, and the structure 30 is movable in at least one rotational movement freedom on a rotation axis oriented perpendicular to the movement plane. Thus, at least one of the front and / or rear first fastening interfaces 37a, 37b can pivot relative to the base 20 about a rotation axis oriented perpendicular to the movement plane. This can also be achieved, for example, by arranging or forming guiding means on or in the base 20 and / or the structure 30; the corresponding guiding means can in turn be, for example, guiding grooves, and guiding bolts serving as fastening elements are installed in the guiding grooves so as to engage therein. The corresponding guiding grooves can be arranged or formed, for example, in a straight line or a curve, in a direction parallel to the transverse axis of the base 20 or at an angle to this transverse axis, that is, especially at an angle to this transverse axis, on or in the base 20 or the structure 30.

[0115] Figure 4 、 Figure 5 It is also shown that the front and rear first fastening interfaces 37a, 37b can be specifically arranged or formed, for example, in the support surfaces 33a, 33b, and these support surfaces 33a, 33b form a flat support on the upper side 21 of the base 20. In this way, although the structure 30 has at least one translational and / or rotational movement freedom relative to the base 20, stable fastening of the structure 30 to the base 20 can still be achieved.

[0116] Finally, from Figure 4 、 Figure 5As can be seen, the snow sliding device 10 can have a second fastening interface in the form of a hole or aperture for one or more ski bindings, to which the ski boots can be fastened via these interfaces. In an exemplary embodiment, the second fastening interface is arranged or formed on or in the structure 30. Thus, in all embodiments, the structure 30 can have one or more second fastening interfaces for fastening the bindings for the user. Specifically, the structure 30 can include a plurality of second fastening interfaces for fastening a first binding, which are arranged or formed in the region of the first free end (front free end) of the structure part facing the base 20, and one or more second fastening interfaces for fastening a second binding, which are arranged or formed in the region of the second free end (rear free end) of the structure part facing the base 20.

[0117] The corresponding second fastening interfaces can be, for example, positive and / or non-positive fastening interfaces, such that the bindings can be fastened to the structure 30 using positive and / or non-positive fastening methods. In particular for positive and / or non-positive fastening types, these can enable the bindings to be attached to the structure 30 in a manner that can be disassembled (without damage or destruction) when required. The positive and / or non-positive fastening types can specifically be clamping, screwing or tensioning or latching fastenings; thus, the corresponding fastening interfaces can be, for example, clamping, screwing or tensioning or latching interfaces, so that openings that can be at least partially penetrated by screws or bolts can be considered, for example.

[0118] Based on the exemplary embodiment according to Figure 6 which shows a cross-section of the corresponding snow sliding device 10 taken approximately in the central region, it can be seen that in addition to at least one first bend 32a extending in the longitudinal direction of the base 20 as described above, the first elastic region 31 can also have at least one second bend 32b (lateral bend) extending in the width or lateral direction of the base 20. Thus, at least with respect to the second region 36, the structure 30 can be a dome-shaped or domed component; thus, due to the bends in the longitudinal and lateral directions, at least the first elastic region 31 can be dome-shaped or domed. By shaping the first elastic region 31 to have at least one first bend 32a extending in the longitudinal direction of the base and at least one bend 32b extending in the width or lateral direction of the base 20 and the resulting three-dimensional shape of the structure 30, another measure is provided to specifically influence the structural properties of the structure 30 and thus the structural properties of the snow sliding device 10.

[0119] The geometric parameters of the respective first bending portions 32a and second bending portions 32b of the first elastic region 31, i.e., in particular their respective radii R, may be the same or different; the specific geometric parameters of the respective first bending portions 32a and second bending portions 32b also provide a measure for in particular influencing the structural characteristics of the structure 30 and thus the final structural characteristics of the snow sliding device 10.

[0120] As can be seen from Figure 7 and Figure 8 it is also conceivable to configure at least one structure 30 to have a plurality of second regions 36, each second region being separated from one another by at least one gap. One, several or all of the second regions 36 may be arranged parallel to the longitudinal axis A1 of the base body 20 (see Figure 7 ). Alternatively or additionally, one, several or all of the second regions 36 may be arranged at an angle to the longitudinal axis A1 of the base body 20 (see Figure 8 ). In two exemplary embodiments, it is also shown that at least two of the plurality of second regions 36 may be arranged parallel to one another. At least two of the plurality of second regions 36 are the same or different in size in the longitudinal and / or transverse directions (although not shown). Regardless of their orientation and / or position or their size, the elastic region 31 may be formed by or include a plurality of second regions 36 that are separated from one another by at least one gap. Thus, the number, orientation and / or position of the respective second regions 36, in particular with respect to the longitudinal axis of the base body 20 and / or with respect to one another, and the size of the corresponding second regions 36 also provide a measure for in particular influencing the structural characteristics of the structure 30 and thus the final structural characteristics of the snow sliding device 10.

[0121] in accordance with Figure 10 、 Figure 11Based on a view approximately transversely cut through the central region of the base body 20, it can be seen that in addition to the structural body 30, the base body 20 can also be constructed in a special way in order to improve the final structural characteristics of the snow sliding device 10 and the associated sliding characteristics. As described above, the base body 20 can have a first base body portion 24, a second base body portion 25, and a third base body portion 26 in the longitudinal direction. The first base body portion 24 has a first free end, the second base body portion 25 has a second free end, and the third base body portion 26 is arranged between the first base body portion 24 and the second base body portion 25 as shown, wherein the third base body portion 26 includes at least one second elastic region 27, and the second elastic region 27 is formed by at least one concave bending portion extending in the longitudinal and / or transverse direction of the base body and having elastic resilience characteristics. In an exemplary embodiment, the second elastic region 27 of the base body 20 is formed by a relatively thin wall thickness of the base body 20. Specifically, the second elastic region 27 of the base body 20 can thus be formed, for example, by a depression extending in the longitudinal direction of the base body 20, in particular a groove-shaped or trough-shaped depression, and / or by a protrusion extending in the longitudinal direction of the base body 20 (although not shown). As can be seen from the cross-sectional view, the depression, in particular the groove-shaped or trough-shaped depression, is oriented in the transverse direction of the base body 20.

[0122] The length dimension of the depression and / or the protrusion corresponds to, for example, at least 50% of the maximum length dimension of the base body 20.

[0123] The width or transverse dimension of the depression and / or the protrusion can be constant or variable along its longitudinal length, i.e., for example, decreasing and / or increasing. The depth of the depression and / or the height of the protrusion can also be constant or variable along its longitudinal length, i.e., decreasing and / or increasing. Generally, the corresponding depression and / or protrusion can thus have a constant or variable cross-sectional geometry in the longitudinal direction.

[0124] As Figure 11 shown, the corresponding depression or protrusion in the base body 20 can also be formed in the upper side 21 of the base body 20. This can be useful because the lower side 22 of the base body 20 is provided with a sliding surface 23 or a gliding surface, and thus can be easily machined, for example, for maintenance and / or repair, just like that of a traditional snow sliding device.

[0125] Figure 12 A pure schematic side view of an exemplary embodiment of the snow sliding device 10 with several structural bodies 30 is shown. Each structural body 30 has its own first elastic region 31. Each structural body 30 can be individually attached to the base body 20. Each structural body 30 can also have one or more second fastening interfaces for connecting members.

[0126] For all embodiments, other measures that affect the structural properties of the structure 30 and thus the final structural properties of the snow sliding device 10 can be implemented, since the structure 30 has one or more influencing structures (not shown), in particular in the form of local strengthening and / or weakening, in at least one direction, in particular in the longitudinal direction and / or the transverse direction of the base body 20, locally affecting the elastic resilience properties. Corresponding local strengthening can be achieved, for example, by geometric structure parameters, such as (relatively) higher wall thicknesses, material accumulations, strengthening geometries (such as rib geometries), etc. Similarly, corresponding local weakening can be achieved, for example, by geometric structure parameters, such as (relatively) lower wall thicknesses, material cuts, weakening geometries (such as openings), etc.

[0127] Finally, it can be seen from Figure 13 、 Figure 14 that the second elastic region 27 or at least one second bending portion 27a forming the second elastic region 27 can be at least partially integrated into the base body 20 and, if desired, completely integrated into the base body 20. Specifically, the second elastic region 27 or at least one second bending portion 27a forming the second elastic region can be formed by the core structure 28 of the base body 20, which has at least one second bending portion 27a extending in the transverse direction of the base body 20. Thus, the second elastic region 27 can be formed by the core structure 28 of the base body 20, which is arranged within the base body 20 and is located between the upper side 21 and the lower side 22 of the base body 20, and the core structure 28 has at least one second bending portion 27a extending in the transverse direction of the base body 20.

[0128] Regarding the types of at least one first bending portion 32a and at least one second bending portion 27a, they can be configured to be in opposite directions. Thus, the first elastic region 32a can, for example, have at least one convex bending portion extending in the longitudinal direction of the base body 20, and the second elastic region 27 can have at least one concave bending portion extending in the transverse direction of the base body 20. In principle, it is also conceivable that the bending portions 32a and 27a are of the same type of construction; both constructions are shown by way of example in Figure 13 、 Figure 14 。

[0129] Specifically, the first elastic region 31 can have at least one convex bending portion 32a extending in the longitudinal direction of the base body 20, and the second elastic region 27 can be formed by the core structure 28 of the base body 20, which has at least one concave bending portion extending in the transverse direction of the base body 20. Surprisingly, it has been found in tests that this construction of the snow sliding device 10 has particularly useful properties in terms of sliding characteristics and performance.

[0130] A method for manufacturing a snow sliding device 10, specifically including the following steps: providing a plate-shaped base body 20 defining a longitudinal axis A1 and having an upper side 21 and a lower side 22, wherein the base body 20 has at least one second elastic region 27, and a sliding surface 23 on the lower side 22 for sliding on snow, the second elastic region 27 being formed by at least one second bending portion extending in the transverse direction of the base body 20, and the second elastic region 27 having an elastic resilience characteristic; and fastening at least one structure body 30 on the upper side of the base body 20, wherein at least one structure body 30 has at least one elastic region 31, the elastic region 31 being formed by at least one first bending portion 32a extending in the longitudinal direction of the base body 20, and the elastic region 31 having an elastic resilience characteristic.
