    The invention relates to a cross-country ski with at least one means for Rückgleithem-determination, as indicated in the preamble of claim 1.
    The US 5,292,147 A describes a cross-country ski, which is designed specifically for the classic cross-country skiing style. Such a cross-country ski has, in the middle longitudinal section, a so-called climbing zone in which a back-restraining means, for example a climbing aid profiling or a climbing wax zone, is formed. The front and rear end sections of this cross-country ski define the casting zones of the cross-country ski. Such Schier have an arcuate, upwardly curved Schivorspannung, whereby the riser zone in the unloaded or moderately loaded condition with the ground does not or only slightly comes into contact. Only at elevated pressure load of the central region, as occurs in the classic Schilangfauf especially in the so-called repulsion phase, this middle section comes into contact with the ground and thus allows Rückgleithemmung or the construction of a repelling force by the user of cross-country ski. In order to achieve an improved flattening of this cross-country ski during the kick-off phase, it has been proposed to provide a slot or opening extending transversely to the cross-country ski through which the cross-country ski has an upper strand body and a lower strand body in the area of the shoe contact zone. With punctual loading of the upper strand body in the course of a repulsion movement by the user of the cross-country ski, the upper strand body easier to dodge down or buckle and thus cause a stronger or more intensive flattening of the underside of the cross-country ski. Such a transverse slot in Gleitbrettkörper is relatively expensive to implement in the course of the production of a cross-country ski and thus only partially suitable for the market. In addition, such kink or lead. Eindrückbewegungen in the upper flange of the cross-country ski to get used to the characteristics of cross-country skiing and also to increased mechanical stress on the strength-relevant elements of such a cross-country skiing.

    The present invention has for its object to provide a cross-country ski, which allows an optimized transition or change between sliding and repulsion phase especially in the exercise of classic cross-country skiing and still has a very economical and robust construction.
    This object of the invention is achieved by a cross-country ski according to the features in claim 1.
    A resulting from the cross-country skiing according to the invention according to the features of claim 1 advantage is that an optimized transition or change between sliding and repulsion phase, and vice versa, can be achieved. In particular, an improved pressure or force transmission to the subsurface of the cross-country ski, in particular to underlying snow surfaces, is achieved by the additionally integrated force distribution element, which is formed immediately above the climbing or repelling zone. Especially when the user of such a cross-country skiing predominantly transfers his body weight to only one of the cross-country skis to be used in pairs, then his climbing or kicking zone comes into comparatively intimate or intensive contact with the ground, so that a comparatively delay-free or impulsive Repelling movement is executable. This pressure or Kraftverteilungseiement allows above all a much kontroliiertere or more targeted transmission of repelling forces of the user on the underside of the cross-country ski, especially in relation to the climbing or repelling zone. Moreover, it is possible by simple position or length variations between the power distribution element and the predefined climbing or repelling zone of the cross-country ski in a simple manner, with minor structural modifications and with relatively marginal production engineering modifications a variety of different types or characteristics to provide cross-country skiing. In addition, a cross-country ski constructed according to the invention is relatively easy to produce and thus cost-effective with respect to the overall production costs, which favors its market acceptance and its economic success. In addition, a cross-country ski constructed according to the invention is relatively robust with regard to increased loads and with respect to above-average loads. In addition, the risk of delamination with respect to the penetration of moisture into the interior of the sliding board body is minimal, so that the cross-country ski according to the invention also has a high practicality. N2010 / 26100
    The measures according to claim 2 are also advantageous, since the mechanical properties of the force distribution element, in particular its elasticity or flexural strength characteristic values, have a relatively direct influence on the climbing or repelling zone on the underside of the tread covering. As a result, a relatively targeted power transmission with respectively desired properties or characteristics in terms of construction can be implemented particularly easily.
    A particularly practical embodiment is specified in claim 3. Such a pressure transmission construction allows a relatively impulsive or delay-free transmission of repulsive forces or pressure forces starting from the user's sports shoe to the underside, in particular to the climbing or kicking zone of the cross-country ski. In addition, this design is particularly useful in terms of production technology and also the requirements for robustness and everyday practicality of such a running cross-country ski are well met.
    Also advantageous are the measures according to claim 4, since this creates a type of punch or pressure plate function, which is a relatively uniform transmission of repulsive or compressive forces starting from the top of the sliding board body towards the underside, in particular in the riser - Or rejection zone allows.
    An optimized ratio between the usual height of the sliding board body and the height or thickness of the force distribution element is achieved by the measures according to claim 5. In addition, this ensures a pressure transfer to the entire width of the climbing or repelling zone, so that its re-hindering effect is utilized as effectively as possible, as soon as the user of the cross-country ski applies corresponding loads or repulsive forces.
    Also advantageous are the measures according to claim 6, since abrupt changes in stiffness with respect to the bending characteristic of the sliding board body can be avoided in a simple manner and virtually predefined buckling points or abrupt characteristic changes in relation to the bending behavior of the sliding board body can be kept behind. In addition, optimized bending stiffness or elasticity parameters for the force distribution element can be achieved thereby.
    By means of the measures according to claim 7, abrupt transitions or abrupt changes with respect to the bending characteristic of the sliding board body are avoided. A significant advantage lies in the fact that especially the strength-relevant lower flange of the cross-country ski experiences no spontaneous or too intensive changes of direction, but may be relatively uniform or uniform, so that so-called kinks or strong changes in the Force direction are avoided.
    Due to the design according to claim 8 a good, in particular as delay as possible transmission of compressive forces is ensured starting from the top of the sliding board body in the direction of the underside. A significant advantage is also that the measures specified a core of a relatively lightweight, such as porous, material can be used within the sliding board body, which core favors a lightweight construction of Gleitbrettkörpers. Despite this porous and relatively little pressure-resistant Kemelementes, for example, a polyurethane foam or a honeycomb body, a transmission of high forces is relatively delay achievable.
    Also advantageous are the measures according to claim 9, since such a force distribution element is easy to work, can be constructed relatively lightweight and still performs a good pressure or force distribution function. In addition, such a force distribution element is simple and functionally reliable implementable in the structure of the sliding board body.
    Of particular advantage are the measures according to claim 10, since thereby the lower belt mechanical, in particular force-related influence on the force distribution element exerts. In particular, in deflections of the sliding board body down the lower chord is claimed to train, so quasi stretched, whereby the force distribution element tends to be pushed down. Thereby, an improved introduction of loading or pressure forces in the central climbing or repelling zone is achieved when the user opposite the top of the cross-country ski repulsive movements exerts. To some extent, the force distribution element is spanned by the lower chord, so that in the case of changes in shape, in particular during stretching of the lower chord, a force is effectively introduced onto the upper side of the force distribution element and thus onto the riser or repulsion zone.
    Also advantageous are the measures according to claim 11, since thereby the force effects of the lower flange, in particular its loads, to a great extent on the pressure or. Force distribution element to be transmitted or transferred. N2010 / 26100 -5-
    By the measures according to claim 12, an optimized compromise between a lightweight construction of Gleitbrettkörpers and sufficient load capacity and pressure transmission capability is achieved. In particular, despite a relatively lightweight and usually less pressure-resistant Kemelementes intensive transfer of pressure loads, starting from the top of the sliding board body toward the underside, be accomplished.
    Due to the configuration of claim 13, a lightweight cross-country skiing is created, which still allows a good, especially a delay possible as possible transmission of pressure loads. Above all, with such a cross-country skiing an optimized weight and power ratio, in particular an increased performance can be achieved.
    Also advantageous is a development according to claim 14, characterized in that the climbing or repelling behavior of cross-country skiing in a simple manner the individual needs or the prevailing conditions, in particular the different snow conditions, can be adjusted in a simple manner.
    Also advantageous are the measures according to claim 15, as this relatively limp Rückgleithemmer, especially filing or brush-type Rückgleithemmer can be used without increased handling costs or increases the risk of replacement.
    Also advantageous are the measures according to claim 16, as it also porous cores or little moisture-resistant core elements can be used without the risk of delamination or destruction of the Gleitgeräteaufbaus. In addition, the power transmission element is also used in a simple manner as an advantageous receiving or holding element for the Rückgleithemmer or its support element.
    Also advantageous are the measures according to claim 17, since this results in an effective or high-grade utilization of the available, re-hindering surface of the climbing or repelling zone. In addition, the risk of unintentional detachment of the Rückgleithemmers or of its supporting element from the sliding board body, in particular with respect to the recess, held back. N2010 / 26100 -6-
    Finally, the measures according to claim 18 are also advantageous, since thereby the shell body is supported load-transmitting on the lower flange, so that the forces exerted on the U-shaped shell body loads or compressive forces are transmitted to a high degree on the lower flange of Gleitbrettkörpers and then on the force distribution element efficiently forwarded to the climbing or repelling zone.

Also, the location information chosen in the specification, such as. top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions. All statements on ranges of values in the description of the present invention should be understood to include any and all sub-ranges thereof, e.g. is the statement 1 to 10 to be understood that all sub-areas, starting from the lower limit 1 and the upper limit 10 are included, ie. all subregions begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1, or 5.5 to 10.
    A cross-country ski 1 will be described with reference to FIGS. 1 to 5, which has at least one means for preventing or inhibiting backward sliding movements. Such a cross-country skiing 1 belongs to the genus of so-called cross-country or back-country skis, which are provided on the one hand for gliding and on the other hand for the most effortless coping with gradients. The specified ski can also be designed as a so-called touring or Mountaineering ski. That is, the ski disclosed herein may be designed as a cross country ski 1 for well-groomed or unpaved terrain, but also as a ski for the practice of mountaineering sport.
    1 shows an exemplary embodiment of a generic ski, in particular a cross-country ski 1, which in a manner known per se in the middle longitudinal section, that is to say in the binding mounting section, has a defined preload height 2 - also the pivot voltage N2010 / 26100 * * * * * m -8 - named - has. By means of this preloading height 2, the middle longitudinal section of a lower side 3 of a gliding board body 4, which essentially defines the ski, in the unloaded state or under load conditions below a predetermined threshold, is distant from a planar surface. This preload height 2 is dimensioned comparatively larger in cross-country ski 1 or in so-called cross-country ski, as in so-called touring or Mountaineering Schiem. In the case of a touring or mountaineering ski, on the other hand, the longitudinal section, in which there is a means for rear hindering, is usually larger in size than in cross-country skiing or cross-country skiing. In such Touring skis, the Rückgleithemmende longitudinal section can namely extend over the entire length of the tread of the ski body.
    With regard to the longitudinal direction of the ski, in a cross-country ski 1, which is the preferred kind of ski, at least one centering device for retraction inhibiting, that is to say a climbing or kicking zone 5, is formed at least in the central longitudinal section of the sliding board body 4. In particular, in the region of a binding mounting zone or in the region of a shoe contact section on the underside 3 of the gliding board body 4, a back-hemming section is provided which comprises at least one known backlash hammers 6 and thus forms the at least one climbing or kick-off zone 5. The climbing or kicking zone 5 usually extends in about more than a third of the ski length. Optionally, this section can also be made shorter, or even run almost over two-thirds of the ski length. In any case, the climbing or repelling zone 5 is only partially executed with respect to the total length of a cross-country ski 1 on its underside 3.
    Optionally, a back-up damper 6 forming the climbing or kicking zone 5 may, as required, be releasably secured to the underside 3 of the sliding board body 4, as exemplified in FIG. According to an advantageous embodiment variant of the Rückgleithemmer 6 executed scaly profile-like. However, the Rückgleithemmer 6 may also be implemented in a filing or brush. It is essential that the respective Rückgleithemmer 6 causes in a first direction of movement, in particular in a common direction of travel of the cross-country ski 1, the lowest possible sliding resistance to the ground and in a second, opposite direction provides the highest possible braking or Verkrallungswirkung compared to the ground, so that the corresponding climbing or repelling zone 5 can act as a slip-back protection or as a climbing or kicking aid. N2010 / 26100 -9-
    The climbing or kicking zone 5 can thus be either an integral, for example chemically or mechanically processed, section of a running surface covering 7 of the sliding board body 4, or designed as a structurally separate section, as was shown by way of example in FIG.
    As best seen in Fig. 5, the gliding board body 4 is typically multilayered. Such a gliding board body 4 comprises at least one strength-relevant top chord 8, at least one strength-relevant bottom chord 9 and at least one core 10 arranged therebetween, which can be designed as a filling core or as a statically significant or relatively insignificant core element. In addition, the multilayer gliding board body 4 comprises at least one decorative or cover layer 12 forming at least the upper side 11 of the gliding board body 4. Furthermore, the multilayer gliding board body 4 comprises at least one tread surface 7 defining the underside 3, at least one rising or pushing zone 5 at its lower flat side is designed to achieve a Rückgleithemmung. In particular, this climbing or repelling zone 5 is formed on the side facing away from the core 10 underside of the tread covering 7 and executed in relation to the Schilängsrichtung in the central portion of the Laufflä-chenbelages 7.
    The respective strength-relevant elements, in particular the upper flange 8 and / or the lower flange 9, can be formed by any elements or layers known from the prior art. In particular, these elements can be made in one piece, in several parts, integrally or otherwise. What is essential is primarily that the corresponding gliding board body 4 achieves the required static characteristics by means of these straps or elements which are strong enough to withstand strength, and nevertheless the construction is as lightweight as possible. For example, these tension or pressure-voltage-relevant straps can be formed by so-called prepreg elements, by metallic elements, by plastic elements, by composite materials, such as CFRP elements, or by similar elements.
    An essential design feature of the invention is defined by at least one additional pressure or force distribution element 13, which is integrated in the gliding board body 4 or defines an integral part of the gliding board body 4. This pressure or force distribution element 13 is arranged between the core 10 of the sliding board body 4 and the upper side 14 of the tread pad 7 facing the core 10. It is particularly expedient here, the power distribution N2010 / 26100
    between the upper side 14 of the tread covering 7 and the lower side of the strength-relevant lower flange 9 to arrange or train.
    It is essential that the pressure or force distribution element 13 acts on the upper side 14 of the tread surface 7 and thereby has at least on the riser or repelling zone 5 influence. In particular, the pressure or force distribution element 13 serves to influence, preferably to even out, the forces to be transmitted to the climbing or kicking zone 5, in particular pressure forces exerted by the user of the cross-country ski 1 on the multilayer sliding board body 4. In particular, a more homogeneous or specifically controllable transition or transmission of compressive forces, starting from the user's shoe on the upper side 11 of the gliding board body 4, into the climbing or repelling zone 5 on the underside 3 of the gliding board body 4 is achieved by the force distribution element 13.
    It is expedient if the pressure or force distribution element 13 extends in relation to the Schilängsrichtung in about 50% to 200%, in particular over 80% to 120% of a length 15 of the riser or repulsion zone 5 and thereby in relation overlaps on the Schilängsrichtung großteiis at least with the riser or repelling zone 5, or covers the riser or repulsion zone 5 over its entire length 15 or bridged. As a result, the pressure or force distribution element 13 can exert a targeted or to a certain extent controllable pressure or force distribution, whereby the riser or repulsion zone 5 in the desired intensity or under full contact as possible with the ground can enter into force and thus a Improved Rückgleithemmung can unfold, as illustrated in Fig. 4 graphically or was compared by schematic characteristics with conventional structures or faced.
    It is particularly effective when the force distribution element 13 of the top surface 14 of the tread 7 is assigned directly, in particular with the tread surface 7 is bonded directly, so that the force distribution element 13 in the overlap area with the Rückgleithemmer 6, in particular in the overlap or overlap area with the Rising or repelling zone 5, load-bearing on the upper side 14 of the tread covering 7 is supported. It has been found to be expedient in this case to bond the force distribution element 13 largely rigidly with the upper side 14 of the tread covering 7 or to weld it.
    As best seen in a synopsis of Figs. 2 and 5, the force distribution element 13 is preferably plate-like. Such a plate-like Kraftver- N2010 / 26100 -11 - dividing element 13 allows an effective power transmission or pressure distribution to the riser or repulsion zone 5 of Gleitbrettkörpers 4. To reduce the mass or increase the adhesion to surrounding layers or elements, the plate-like Force distribution element 13 has a plurality of depressions or openings 16, which may expediently extend between the opposite flat sides or may be formed on at least one flat side, as was indicated by dashed lines in Fig. 5 by way of example. Such breakthroughs 16 or surface structuring in the form of depressions or elevations on Kraftverteiiungselement 13 favor a lightweight construction as possible without thereby significantly affect the pressure distribution function or force transmission function of the plate-like force distribution element 13. In addition, by these measures, the risk of delamination of the structure of the sliding board body 4 are kept back.
    It is expedient if the force distribution element 13 has a thickness 17 between 1 mm to 10 mm, preferably of approximately 4 mm, in order to achieve a sufficient bending stiffness and force distribution. It is advantageous if the force distribution element 13 has a transverse width measured to the ski direction, which corresponds to a width 18 of the tread surface 7 in the region of the riser or repelling zone 5 or at least approximately. As a result, a kind of press ram is created, which effectively and relatively uniformly transfers the force exerted by the user on the gliding board body 4 repulsion or use forces on the climbing or repelling zone 5. The length of the force distribution element 13 depends primarily on the length of the gliding board body 4 or its bending stiffness characteristic and is typically between 30 cm to 90 cm, preferably between 40 cm to 60 cm.
    To intensify the pressure or force transmission to the climbing or repelling zone 5 of the sliding board body 4, it is expedient if the force distribution element 13 extends continuously between opposing side cheeks 19, 20 of the sliding board body 4, wherein the force distribution element 13 preferably has a width which a width 18 of the tread covering 7 corresponds or at least approximately corresponds, as was shown schematically above all in Fig. 5.
    Furthermore, it is expedient, at least in the central region of the length of the gliding board body 4, or at least in the region of the climbing or repelling zone 5, to cover at least the cover layer 12 of the gliding board body 4 as a shell 22 which is essentially U-shaped in cross-section. This downwardly open, substantially U-shaped shell body 21 defines the so-called "cap" of Gleitbrettkörpers 4. This Schaienkörper 21 is oriented such that its base 22 ausbiidet the top 11 of the sliding board 4 and the two projecting from the base 22 legs 23,24 of this shell body 21 form the opposite side cheeks 19, 20 of the sliding board body 4, as dargesteilt example in Fig. 5. It is particularly favorable if the longitudinal edges 25, 26 of the shell body 21 facing away from the base 22 of the shell body 21 or of its legs 23, 24 support the longitudinal side edges 27, 28 of the force distribution element 13 in a load-transmitting manner. As a result, a pressure transmission structure 29 is provided, which is formed mainly by the shell body 21 and the core 10, and with which the forces to be transmitted from the top 11 of the sliding board 4 on the underside 3 can be forwarded as delay or unattenuated, although the Core 10 of the GleKbrettkör-pers 4 per se may be relatively compliant, in particular may be formed by polyurethane foam. In particular, by means of this pressure transmission construction 29, despite an inherently porous or less pressure-resistant core 10, an impulsive or delay-free force or pressure transfer can be achieved starting from the upper side 11 in the direction of the underside 3 of the sliding board body 4. According to an advantageous embodiment, the core 10 of the sliding board body 4 may be formed by a relatively porous, lightweight plastic, in particular by a foam plastic, such as PU foam. Likewise, the core 10 of the sliding board body 4 may be formed of a structural element having a plurality of cavities, for example a honeycomb body. Despite such cores 10 of materials with relatively low density and per se relatively low compressive strength, an intense or substantially instantaneous transfer of the forces exerted by the user on the top 11 forces towards the bottom 3, in particular in the climbing or repelling zone 5 done. Moreover, such a core 10 is particularly lightweight, whereby the total mass of the sliding board body 4 can be kept low and the sport performance achievable thereby can be promoted or increased.
    In contrast, the material forming the force distribution element 13 has a density, in particular a material density, which is approximately 2 to 15 times, in particular approximately 5 to 10 times, higher than a density, in particular a material density, of the core 10 Thus, the power transmission or force distribution is optimized with respect to the riser or repelling zone 5, after the increased density N2010 / 26100 -13- or the higher compressive strength of Kraftverteiiungseiementes 13 the pressure distribution or power transmission compared to the material of Kerns 10 improved.
    Preferably, the force distribution element 13 is made of plastic, in particular of hard plastic, such as HDPE. Alternatively, it is also possible to achieve the increased pressure resistance of the force distribution element 13 - compared to the compressive strength of the core 10 - by the use of wood or a composite material, for example by a CFRP element with high compressive strength and dimensional stability. The respective, relatively pressure-resistant and dimensionally stable or dimensionally stable force distribution element 13 -in comparison to the compressive strength or dimensional stability of the core 10 of the sliding board body 4 - is firmly connected to adjacent layers or surrounding elements of the sliding board body 4, in particular rigidly glued to them, so that a one-piece , multi-layered unit is created.
    According to a first embodiment according to FIGS. 1 to 5, the strength-relevant lower flange 9 is not or only partially visible, as can be seen from a synopsis of FIGS. 2 and 5. In contrast, the preferably plate-like force distribution element 13 is at least partially visible or led out on the side cheeks 19, 20 of the Gieitbrettkörpers 4, as best seen in FIGS. 2 and 5 can be seen. In particular, at least a portion of the thickness 17, preferably the complete thickness 17 of the force distribution element 13, on at least one side cheek 19,20, preferably on both side cheeks 19, 20 of the Gieitbrettkörpers 4, visible or accessible. That is, the opposing side surfaces or side walls of the force distribution element 13 according to an advantageous embodiment define at least a portion of the opposing side cheeks 19, 20 or side surfaces of the Gieitbrettkörpers 4, as best seen in FIGS. 2 and 5. Opposing side walls of the force distribution element 13 thus form lateral boundary surfaces of the Gieitbrettkörpers 4, wherein these lateral boundary surfaces increase the robustness of the Gieitbrettkörpers 4. As best seen in Fig. 2 it can be seen, the opposite longitudinal edges 25, 26 of the legs 23, 24 of the shell body 21 are based in sections outside the climbing or repelling zone 5 directly on the top 14 of the tread 7 from. Optionally, between the said elements and the lower flange 9 extend, as shown in FIGS. 7 and 8. However, in the region of the rising or pushing zone 5 or in the region of the binding mounting zone, the longitudinal edges 25, 26 of the shell body 21 N2010 / 26100 are preferably supported on the upper longitudinal side edges 27, 28 of the force distribution element 13.
    As best seen from a synopsis of Fig. 7, 8, it is expedient if the strength-relevant lower flange 9 of the sliding board body 4 with respect to the Schilängsrichtung without interruption between the front and rear sliding zone 30, 31 of the sliding board body 4 extends the strength-relevant lower flange 9 runs in the region of this front and rear sliding zone 30, 31 of the sliding board 4 relatively close to the top of the tread 7. In particular, the lower flange 9 in the region of the front and rear sliding zone 30, 31 immediately adjacent to the top 14 of the tread 7. In the region of the climbing or repelling zone 5, this strength-relevant lower flange 9 then extends beyond the force distribution element 13, so that it is distanced comparatively farther from the upper side 14 of the running surface covering 7 in the region of the riser or repelling zone 5. Viewed in side view-according to FIG. 7 -the lower flange 9 preferably extends over the force distribution element 13 in a curved manner. The strength-relevant lower flange 9, which is subjected to bending of the gliding board body 4, thereby causing a force transfer to the force distribution element 13, so that this is pressed as completely as possible down and thus relatively intensively initiates the corresponding forces in the climbing or repelling zone 5. A downward sliding board body 4 transmits so by the specified course of the lower flange 9, which extends over the entire length or at least over long longitudinal sections of Gleitbrettkörpers 4, the corresponding forces amplified on the power transmission element 13 and subsequently on the climb or Shock zone 5, so that they can come into defined contact with the respective ground, for example snow or ice. In particular, the force distribution element 13 is virtually spanned or bridged by the lower flange 9, as best seen in FIG. 7. Accordingly, the construction of the gliding board body 4 is executed such that the force distribution element 13 is arranged between the running surface covering 7 and the strength-relevant lower belt 9, which is predominantly tension-stressed, and is non-positively connected, in particular adhesively, to said components.
    According to the embodiment according to FIG. 8, the strength-relevant lower flange 9 has a width 32 at least in the region of the rising or pushing zone 5 of the sliding board body 4, which corresponds to a width 18 of the preferably plate-like force distribution element 13 or at least approximately corresponds. In this embodiment, N201 <V26100 -15- is supported by a substantially U-shaped shell body 21 which forms the top 11 and at least portions of the side cheeks 19,20 of the gliding board body 4 with the interposition of the bottom chord 9 on the top of the force distribution element 13 off. This means that in the embodiment according to FIG. 8, the longitudinal side surfaces of the lower flange 9 on the side walls can be seen, in particular on the side cheeks 19, 20 of the sliding board body 4 are accessible. With respect to an intensive power transmission and with respect to favorable static characteristics, it is expedient if the longitudinal side surfaces of the lower belt 9 define sections of the lateral boundary surfaces or boundary walls of the sliding board body 4, as can be seen in FIG.
    According to an alternative embodiment, as shown in Fig. 6, a width 32 of the lower flange 9 may correspond to the clear width between the legs 23, 24 of the shell body 21 or be slightly smaller than the clear width between the legs 23, 24 of the Shell body 21. In particular, the lower flange 9 and also the force distribution element 13 is covered by the shell body 21, in particular completely concealed. In this embodiment, the longitudinal edges 25,26 of the shell body 21 are supported on the longitudinal side edges of the tread surface 7. Accordingly, a width 32 of the lower flange 9 and the force distribution element 13 is somewhat Weiner dimensioned as the width 18 of the tread covering 7 in the region of climbing or repelling zone 5. Thus, although a force distribution element 13 ausgebiidet in the region of rising or repelling zone 5, the latter is However, due to the pulled down to the tread surface 7 down legs 23, 24 of the shell body 21 is not visible or not accessible.
    The relative position between the climbing or repelling zone 5 and the force distribution element 13 with respect to the longitudinal direction can be adjusted or changed in the course of the production of the cross-country ski 1 in view of the respective desired properties of the cross-country ski 1 in a simple manner. Thus, in the embodiment according to FIGS. 1 and 2, the force distribution element 13 is made comparatively longer than the climbing or repelling zone 5. In this case, the force distribution element 13 bridges the climbing or repelling zone 5 both with respect to the front and with respect to the rear end portion the riser or repelling zone 5. To change the riser-o repelling effect, in particular to achieve an optimal transition between sliding and repelling phase, only a partial overlap in the longitudinal direction between the force distribution element 13 and the riser or repulsion zone 5, which the Ν2010 / 2Θ100 Rückgleithemmer 6 includes, may be provided. In the embodiment according to FIG. 7, the force distribution element 13 is slightly set back relative to the climbing or repelling zone 5, in particular displaced in the direction of the rear end of the cross-country ski 1. Likewise, the force distribution element 13 can be quasi forward offset and thus surmount the front end portion of the riser or repulsion zone 5 quasi. In addition, the climbing or repelling zone may have a length 15 - Fig. 1 - which is dimensioned larger than the longitudinal extent of the immediately above the force distribution element 13 positioned thereby. Depending on the desired characteristics of the cross-country ski 1 with relatively simple production engineering measures of the respective desired cross-country ski 1 or respectively the required behavior can be achieved economically and efficiently.
    In FIGS. 3, 4, such an influencing of the characteristic, in particular the influence of the force distribution element 13 on the usage behavior or on the soil distribution of a cross-country ski 1, is illustrated graphically and by way of example. The characteristic curves 33, 34, 35 shown in FIG. 4 are to be regarded as completely schematic and exemplary and serve only to illustrate the achievable effects or effects.
    For the sake of simplicity, an embodiment is shown in Fig. 3, in which the force distribution element 13, the climbing or repelling zone 5 completely, that is vome and rear at least slightly bridged. The characteristic curve 33 in accordance with FIG. 4 shows that the formation of the force distribution element 13 makes it possible to achieve a relatively uniform ground pressure distribution-characteristic curve 33. In particular, by means of the force distribution element 13, the contact pressure exerted by the climbing or repelling zone 5 on the substrate can largely be uniformized or evened out over the entire longitudinal extent of the climbing or repelling zone 5. In contrast, in conventional constructions without a force distribution element 13, a significantly more irregular ground pressure distribution can be observed. In the known from the prior art training - for example, according to the characteristic curve 34 shown in dashed lines - it may occur in the front and rear end portion of the riser or repelling zone 5 punctually to relatively high ground pressure values, while the central portion of the riser or repulsion zone. 5 is pressed comparatively weak against the Unteigrund and can muster only comparatively lower Anpresswerte or ground pressure forces. Likewise, it can degenerate in the known from the prior art embodiments - according to the characteristic curve 35 shown in dash-dotted lines - that especially the central region of the riser or repelling zone 5 comparatively intense, that is N2010 / 26100 ·· ft ·· ft * ftft ft ft
    • · · · · · · · · · · · · · · · · · · · · · ·------------------------ is pressed with high contact forces against the ground, while the front and / or the rear end portion of the riser or repelling zone 5 comparatively low contact forces or contact pressures against the ground achieved. These relative to the respective gradients relatively strongly fluctuating curves 34,35 according to the known from the prior art versions have a relatively unfavorable effect on the change between sliding and repulsion phase during the intended use of a cross-country ski 1 from. In contrast, by the significant equalization of Anpress- or bottom pressure ratios in the region of the Kraftverteilungselemen-th 13 a controlled and controlled, in particular almost full-surface exploited pressing the riser or repelling zone 5 carried against the ground, so that the user of a Langfaufschis 1 according to the invention with appropriate Strain an optimal repulsion and with appropriate relief an immediate transition to an optimal sliding phase, and vice versa, implemented or can be achieved. An advantageous effect of the specified force distribution element 13 is that the sliding or repelling zone 5, in particular its Rückgleithemmer 6, is used as effectively as possible.
    It has been shown that by the specified training and arrangement of the pressure or. Force distribution element 13, the maximum effective area of the riser or repulsion zone 5 and the respective Rückgleithemmers 6 can be used as highly as possible for use.
    For further optimization of the characteristics of the characteristic curve 33 of a cross-country ski 1 designed according to the invention, the measure shown in FIG. 3 can furthermore be provided above all. In particular, it is expedient to carry out the force distribution element 13 on at least one of its longitudinal ends 36, 37, in particular on the front and / or rear longitudinal end 36, 37, in a tapered manner. Preferably, at the front and rear longitudinal end 36, 37 of the force distribution element 13 in each case a flattening or run-on slope 38,39 is formed. These flattenings or Aniaufschrägen 38, 39 form a shortened compared to the underside of the force distribution element 13, substantially parallel to the riser or repelling zone 5 extending top of the force distribution element 13, as best seen in FIG. 3 can be seen. Accordingly, the Kraftverteiiungselement 13, starting from the central portion toward at least one of its longitudinal ends 36, 37 with respect to its thickness 17 tapered or made ver-schmälemd. Instead of the arcuate sloping longitudinal ends 36, 37 illustrated in FIG. 3, it is also possible for the force distribution element 13 to be an arcuate or substantially crescent-shaped element in longitudinal section. N2010 / 26100 # · · · · * ································································································································································································································ Shape. This means that the force distribution element 13 can also be executed in the manner of a statically optimized carrier which has its greatest thickness 17 in the middle section and is narrowed or tapered continuously or discontinuously in the direction of the longitudinal ends 36, 37, until finally narrow Outlets or longitudinal ends 36, 37 are present. The abovementioned embodiments favor an optimized course of the characteristic 33, in particular the bending or ground pressure characteristic. In addition, an improved course of the strength-relevant lower flange 9 is achieved by these measures or embodiments. In particular, the lower flange 9 can thus run as directly above the force distribution element 13 as possible without complex positioning measures for the elements mentioned during the production of the sliding board body 4.
    According to an expedient embodiment, the run-on slope 38, 39 formed on at least one longitudinal end 36, 37 of the force distribution element 13 is designed such that it occupies an acute angle 40, 41 with respect to the underside of the force distribution element 13. As advantageous and expedient has been found to provide an angle 40, 41 between 5 ° to 70 °, preferably between 8 ° to 30 °, relative to the substantially planar underside of the force distribution element 13. As a result, a favorable course of the characteristic curve 33 is achieved after inter alia an abrupt change of direction or an abrupt deflection of the strength-relevant lower belt 9 is avoided or held back. In the preferred embodiment of two run-on slopes 38, 39, these angles 40,41 may also be set differently.
    These angles 40, 41, which among other things determine the lengths of the respective run-on slopes 38, 39, can also be used to influence or regulate the course of the characteristic curve 33. In particular at relatively small angles 40, 41, that is to say with flat outlet ends 36, 37, a comparatively flat characteristic curve can be achieved, while at steep angles 40, 41 comparatively more abrupt pressure transitions in the characteristic curve 33 with respect to the sections between the sliding zones 30 , 31 and the climbing or repelling zone 6 are to be observed.
    The force distribution element 13 may be formed in one or more parts, but is preferably designed as a one-piece element. According to the embodiment according to FIG. 9, it is provided to form the force distribution element 13 from at least two interacting elements. In particular, two essentially plate-like pressure distribution bodies 42, 43 are formed. These two pressure distribution bodies 42,43 are arranged one above the other, wherein the upper pressure distribution body 43 is supported load-transmitting on the lower pressure distribution body 42. Expediently, the upper pressure distribution body 43 has a shorter longitudinal extent than the lower pressure distribution body 42. The upper, shorter pressure distribution body 43 is preferably positioned substantially centrally with respect to the longitudinal extent of the lower pressure distribution body 42. Preferably, each of these pressure distribution body 42, 43, which together form a multi-layer or multi-part force distribution element 13, flattened at its front and rear longitudinal ends 36, 37 and tapered. It is expedient - as shown schematically in FIG. 9 - to provide graduated run-on slopes 38, 39. The respective outlets of the force distribution element 13, in particular of the lower pressure distribution body 42 are selected such that they slightly project beyond the front and rear end of the riser or repulsion zone 5, as shown in FIG. 9 by way of example. But it is also possible, both pressure distribution body 42,43 at both longitudinal ends beyond the Längserstre-ckung the riser or repulsion zone 5 protrude, or a supernatant of the riser or repulsion zone 5 with respect to the longitudinal ends 36, 37 of the force distribution element 13 only to provide simple and / or only unidirectional. Furthermore, it is conceivable to dimension the longitudinal extent of the force distribution element 13 by up to 50% shorter than the length 15 of the riser or repulsion zone 5. The shorter the force distribution element 13 is selected with respect to the length 15 of the riser or repulsion zone 5, the lower is the static or pressure-based influence of the power transmission element 13 ausfal-len.
    Likewise, it is possible for the lower and upper pressure distribution bodies 42, 43 to be covered with different materials and / or cross-sectional geometries and thus to achieve different rigidity values. The lower and upper pressure distribution body 42, 43 can also be made different in color.
    In Fig. 10, an advantageous development of a Langiaufschi 1 is illustrated in conjunction with the advantageous force distribution element 13. In this case, at least a portion of the climbing or repelling zone 5 of the cross-country ski 1 is formed by a screed-like return hammer 6. Alternatively, it is also possible to provide a filigree or brush-type backlash hammers. It is essential that the corresponding Rückgieithemmer 6 is in an elongated, running in the ski longitudinal direction recess 44 in the tread surface 7, if necessary removably attached. This makes it possible, under different N2010 / 26100 different types or types of Rückgleithemmern 6 according to the individual needs within the climbing or repelling zone 5 to use and thus to achieve different characteristics.
    According to an expedient embodiment, the backlash damper 6, for example a chemically or mechanically treated covering or a covering with a flake profile 45, is arranged on a comparatively rigid and dimensionally stable support element 46. This support member 46 for the corresponding Rückgleithemmer 6, for example, for filing or brush-like Rückgleithemmer is then at least partially replaceable in the recess 44 in the tread surface 7 and if necessary from the recess 44 in the tread surface 7 again removed. That is, it is a need-replaceable and, if necessary, removable or exchangeable climbing or repelling zone 5 is provided. In addition, if necessary, the climbing or kicking zone 5 can also be converted to a further sliding zone by inserting a running surface section, in particular a sliding lining, into the recess 44 with increased slidability.
    Conveniently, a depth 47 of the recess 44 is dimensioned such that the recess 44 extends into the preferably plate-shaped force distribution element 13. Consequently, a base 48 of the recess 44 is formed or limited by the material of the force distribution element 13. The base 48 of the recess 44 is thus formed by plastic, in particular by a hard plastic. A need-releasable coupling between the support member 46 and the recess 44 is preferably achieved or supported by magnetic action. In particular, at least one permanent magnet 49, 49 ', 49 &quot; arranged, which can be set with the Rückgleithemmer 6, in particular with its support member 46, in and out of magnetic interaction or attraction. The proper mounting of the support member 46 relative to the sliding board body 4 is accomplished on the one hand by the positive connection between recess 44 and support member 6 and additionally by the magnetic interaction between the support member 46 and the permanent magnets 49,49 ', 49 "built or secured.
    It is expedient, furthermore, to dimension a width 50 of the recess 44, measured transversely to the ski direction, to be slightly smaller than the width 18 of the tread surface 7 in the region of the riser or kick zone 5, so that a peripheral boundary 51 of the recess 44 on the one hand passes through the tread surface 7 and on the other N2010 / 26100 • ·
    Is formed by the preferably päattenartige force distribution element 13. According to an advantageous embodiment, the magnetic force or the mutual magnetic attraction is chosen such that a tool-free separation of the support member 46 and the Rückgleithemmers 6 relative to the sliding board body 4 is made possible.

    So are all conceivable embodiments, which are possible by combinations of individual details of the illustrated and described embodiment variant, includes the scope of protection.
