SKI

The present invention relates to a ski, as specified in claim 1. A gliding device, in particular of board type, is specified, this being provided for the practice of winter sports. The ski according to the invention is specifically designed for the practice of alpine skiing on snow.

A generic ski is described in document EP 0 563 569 A1. This ski, in particular intended for alpine skiing, comprises a lower bearing structure, of board type, said lower carrying structure comprising, at at least one of its ends longitudinal, a spatula section oriented upwards. An upper supporting structure is produced at the upper side of the lower supporting structure, said upper supporting structure extending at least inside a mounting area for a ski binding. In the part of the longitudinal center of the mounting area of the binding, said upper supporting structure is divided and / or cut and an elastic spring element can be provided inside this separation and / or heaving plane, this element capable of cooperating on the one hand with the front partial section and on the other hand with the rear partial section of the upper supporting structure divided in two. When the corresponding ski is stressed by buckling, it is either the inserted spring element which is used, or, in the absence of such a spring element, the stiffness of the ski which is increased up to a buckling value determined, by making the front surfaces facing each other of the partial front and rear section of the upper bearing structure meet and support each other. The performance and / or the deployment of power targeted with a ski mounted in such a way are therefore only provided in a satisfactory manner.

Document WO 93/16769 A1 also describes a ski comprising a lower bearing construction of the board type intended to slide on snow. In the part of a mounting mounting area, the lower load-bearing board-type construction has a trough-like recess in the thickness. In this recess, a supporting fixing plate formed in a complementary manner is positioned in the part of the fixing mounting zone. This bearing fixing plate is in this case held in the recess via a viscoelastic intermediate layer. The selected thickness of the fixing support plate is such that the fixing screws used for the ski bindings do not pass through the fixing support plate and are thus only anchored in the fixing support plate. The ski may at least comprise a reinforcing layer of stiffening material in the part of the lower supporting construction in which the recess provided for the supporting fixing plate is formed. The interposed viscoelastic layer must provide flexible coupling between the ski binding and the lower bearing structure. The flexural rigidity of this ski also varies relatively suddenly with respect to its various longitudinal sections in terms of distribution of the flexural rigidity and / or characteristic curve of the flexural rigidity.

The objective of the present invention is to overcome the drawbacks of the state of the art and to make available a ski offering improved performance to a user practicing skiing.

This objective is achieved by a ski according to the claims. A ski according to the invention comprises a lower load-bearing structure and an upper load-bearing structure, said load-bearing structures being preferably connected to each other firmly and / or in a non-detachable manner. The lower supporting structure forms at the level of at least one of its longitudinal ends a spatula section, in the form of an upward arc. The upper bearing structure has a length corresponding at least to a longitudinal extension of a mounting area for a ski binding. Preferably, the length of the upper bearing structure exceeds the opposite end sections of a ski binding. The upper supporting structure is subdivided, by means of at least two transverse slots extending transversely to the longitudinal direction of the ski, into at least three segments and / or partial sections. These transverse slots extend from the upper side of the upper supporting structure, in the direction of the lower supporting structure. At least one of these transverse slots made in the upper bearing structure is arranged outside the mounting area provided for a ski binding.

A ski thus assembled has the advantage of being able to offer a high sporting performance allowing the user dynamic use while allowing the most precise possible guidance of the corresponding ski. This can in particular be obtained by means of a mounting mounting plan and / or a raised shoe imprint surface offering the user large inclined positions and / or edge angles without the sports shoe and / or ski binding comes into contact with the ground below. A characteristic curve of bending and / or a distribution of the stiffness in relative harmonic bending can also be achieved with respect to the longitudinal direction of the ski. This most harmonic bending characteristic curve guarantees the trajectory holding and / or the guiding of the ski with respect to momentum of movement to the left and to the right, so that has an increased controllability of the ski. This makes it possible in particular to create an action

The corresponding user, alternating improved between the height of the footprint of the shoe of the user relative to the ground below and the characteristic curve of flexion which can be obtained for skiing.

The measures according to claim 2 are also advantageous since all the screws and / or pairs of screws placed at a certain distance from each other in the longitudinal direction of the ski are anchored and / or can be anchored to fix the front jaw and that all the screws and / or pairs of screws placed at a certain distance from each other in the longitudinal direction of the ski are anchored and / or can be anchored to fix the automatic heel piece of the ski binding in each different segment of the structure upper bearing. This makes it possible to obtain the smallest possible stiffening of the ski and in particular in the partial sections of the ski located below the front jaw and / or located below the automatic heel piece and / or overlapping them. This makes it possible to obtain the most limited warping possible of the ski and / or a bending characteristic curve as homogeneous as possible. This advantageous effect can be further improved by housing and / or hanging at least one fixing screw and / or at least one pair of fixing screw screws placed at a certain distance from each other in the longitudinal direction of the front jaw and / or the automatic heel piece for the front jaw and / or the automatic heel piece in the oblong recesses and / or the through passages for compensating the length of the front jaw and / or the automatic heel piece.

In this context, the measures according to claim 3 are also suitable because this ensures that the fixing screws positioned at a certain distance from each other relative to a longitudinal extension of the front jaw and / or the automatic heel pieces are each anchored in different segments and / or articulated elements of the upper bearing structure. This makes it possible in particular to avoid and / or simply prevent screws and / or pairs of screws placed at a certain distance from one another from being fixed in a single segment in the longitudinal direction of the jaw front and / or automatic heel.

An embodiment according to claim 4 is also suitable, since it makes it possible to improve the oscillatory behavior of the ski, in particular to attenuate it. This makes it possible to reduce and / or delay the warping between the upper bearing structure and the lower bearing structure when the viscoelastic layer is subjected to shear stress relative to the longitudinal direction of the ski, as occurs in the case of elastic buckling or bending up the ski body.

The measures according to claim 5 according to which the upper supporting structure is connected in a non-detachable manner to the lower supporting structure via a viscoelastic layer disposed between are also advantageous. It is particularly indicated in this case that the upper supporting structure is connected, in particular glued, by complementarity of forces to the lower supporting structure by interposing the viscoelastic layer and / or using the viscoelastic layer. This guarantees a bond by complementarity of forces of the largest possible area between the upper bearing structure and the lower bearing structure, so as to allow, within the framework of such a bonded bond, to constitute and / or make available forces of high bond. Such an adhesive bond using the viscoelastic layer disposed between also allows rational production in series, which allows to keep relatively low manufacturing costs for the ski concerned.

As a variant, it is also possible to use a screw fastening of the upper supporting structure, as indicated in claim 6. An advantage of this embodiment is that this makes it possible to create a multiple, almost punctual connection of the supporting structure. upper with the lower supporting structure, making it possible to produce and / or position the respective connection points and / or fixing screws specifically at the level of the longitudinal positions of the ski at which a high performance connection is indicated and / or necessary between the structure upper and lower load-bearing.

The measures according to claim 7 are also advantageous since the viscoelastic layer defines a sealing layer on the upper side of the lower supporting structure and thus makes it possible to increase the robustness of the ski. This also makes it possible to obtain the most rational manufacturing possible and thus the cheapest possible ski of the invention.

Alternatively, the measures of claim 8 are also suitable. They make it possible to avoid a through and / or uninterrupted viscoelastic layer with respect to the longitudinal direction of the ski. This makes it possible to support at least individual segments of the upper bearing structure on each of the associated, delimited, relatively small and / or adapted partial sections of the viscoelastic layer. Concomitant effects and / or advantages are that, above all inside the transverse slots, the surface sections are as flat as possible and / or without friction in order to make it possible to prevent an undesired accumulation of particles or any other aggregation.

The measures according to claim 9 are also advantageous since they make it possible to obtain an effective and / or optimized mutual alternating action between the upper bearing structure and the lower bearing structure.

The measures according to claim 10 are also particularly suitable since the upper supporting structure is designed in the form of an articulated belt and therefore the upper supporting structure serves mainly to increase the exposure area and / or represents a load-bearing plate for almost integral fixing while its reinforcing and / or warping function is relegated to the background compared to the lower load-bearing structure. It is also advantageous that, if necessary, a screwing of the corresponding parts of the ski binding can occur without problem in segments independent of each other of the upper bearing structure. It is in particular possible to guarantee, by virtue of this high number of transverse slots serving for the formation of at least ten segments, that the influence of rigidity of the upper bearing structure is relatively reduced. The at least ten segments of the upper bearing structure can in this case be hooked to each other autonomously and / or be made at least entirely autonomously from the construction point of view. This can be adjusted and / or selected if necessary simply by means of the respective depth of the transverse slots with respect to the respective cross-sectional height of the upper supporting structure.

The measures according to claim 11 are suitable for maintaining the resistance torque and / or the torque the load-bearing structure of flexural rigidity as high as possible as much as possible and simultaneously obtaining the most homogeneous bending characteristic curve of the total structure of the ski. . One can in particular thus maintain the influence of the upper bearing structure on the bending stiffness of the total construction relatively reduced and the upper bearing structure can thus mainly fulfill the function of an increase in the plane of the ski user according to claim.

The measures according to claim suitable for obtaining a buckling of the lower bearing structure as little as possible possible at least during the impression phase for and / or 13 are the start of buckling of the lower bearing structure and / or the least hampered possible by the upper supporting structure. This makes it possible in particular to delay and / or avoid mutual support of the individual segments of the upper bearing structure up to a certain degree of buckling of the construction of the ski.

The measures of claim 14 may also be appropriate. Penetration of ice or snow into these transverse slots can thus be avoided, especially above all in cases in which the transverse slots are detached and / or accessible from the upper side of the ski. One can thus obtain under unfavorable conditions of use a behavior of constant and / or the most regular possible.

The measures according to claim 15 are also advantageous, since the ski thus structured can be reinforced in longitudinal sections defined via the upper bearing structure and can in particular comprise a relatively high bending torque compared to buckling while this ski has a comparatively lower curvature resistance torque compared to counter-bending movements, in particular compared to elastic upward curvatures of the ski environment relative to the ends of the ski.

To keep the stiffening influence of the upper bearing structure as small as possible, the measures according to claim 16 are also suitable. This makes it possible in particular to subject the ski to relatively reduced buckling in the middle of the ski relative to the ends of the ski. If necessary, the upper supporting structure can thus be produced in the manner of a belt articulated in several parts and / or in the manner of hinge-type segments with butted film.

An improvement according to claim 17 is particularly advantageous. It makes it possible in particular to obtain the safest possible operation and / or the most constant behavior possible also in the presence of unfavorable reports and / or environmental conditions. This allows among other things to delay and / or avoid an accumulation of snow or ice and finally an obstruction of the corresponding transverse slots.

The complementary measure according to claim 18 is also particularly appropriate in this context. It guarantees the lowest possible compressive strength and / or a relatively limited inherent stiffness of the covering film. This can make it possible to form folds by compression and / or curvatures down and / or up relatively few and / or marginal. Such folds by compression and / or such curvatures are in this case made possible with respect to the overlapping sections of the transverse slots and thus contribute to the flexibility of a ski constructed according to the invention as free as possible or least hampered. possible with respect to the covering film.

The measures according to claim 19 make it possible to obtain a structure with as few individual layers as possible. The covering film thus has in particular a multiple functionality since it prevents on the one hand the penetration of snow or ice in the transverse slots and that it also fulfills and / or assumes an aesthetic and / or protective function for the structure of the ski. This measure also guarantees a robust structure and / or the best possible protection before delamination.

The measures according to claim 20 also make it possible to optimize and / or improve the long-term resistance of the ski claimed. It is in particular possible to delay all delamination of the layered structure and in addition to obtain an aesthetic and pleasant appearance.

An advantageous measure is further set out in claim 21. It makes it possible to obtain increased robustness and / or security against improved destruction. This is especially used in the case of a relatively thin covering film and when this covering film spans the transition section between the upper bearing structure and the lower supporting structure.

Particularly high robustness and / or safety against destruction of an especially thin outer covering film can be obtained at the upper side of the ski construction by means of the measures according to claim 22.

The measures according to claim 23 are also advantageous. The embodiment of an upper and lower bearing construction can in particular make it possible to simply obtain an increased imprint plane for binding the ski and / or for the boot of a user. This makes it possible to provide relatively inexpensive bearing plates for fixing between the ski and the ski binding. This thus promotes the efficiency of the ski according to the invention and increases the usability and / or creates a good basis for the widest possible distribution and / or for the penetration of a market.

The measures according to claim 24 are also advantageous, since an at least limited elastic decoupling is maintained between the upper and lower bearing structure of the ski also after the mounting of an ordinary ski binding. It is also advantageous that a fixing attachment can occur directly at the upper side of the ski, also without interposing of a carrying fixing plate. The thickness and / or height of the individual segments and / or segments in the part of the mounting mounting area is suitably greater than 8 mm and / or 10 mm in this case.

A particularly robust and / or tear-resistant connection can be made between the ski binding and the ski by means of the measures according to claim 25. It is in particular thus possible to obtain, without the interposition of a bearing support plate, a binding binding directly at the upper side of the ski. It is also possible to obtain tear strengths and / or tear strengths from a mounted ski binding, the values of which are also sufficient in the event of high loads on the ski body.

For a better understanding of the present invention, it will be explained in more detail using the following figures, in which, in highly simplified schematic representation:

To begin with, it should be mentioned that in the various embodiments described, similar parts are provided with similar references and / or similar component designations and that the presentations contained throughout the description can be given by analogy to identical parts with identical references and / or identical component designations. The position indications chosen in the description, for example at the top, bottom, side, etc. refer to the figure shown and described immediately and these position indications are transferred correspondingly to the new location in the event of a change of position.

Figure 1 illustrates very schematically an embodiment of a ski 1 according to the invention. This ski 1 is in this case intended for the practice of alpine skiing, in particular for the descent of preferably prepared snow slopes. As known per se, such a ski 1 is used in pairs and can in particular be detachably placed on the left and right foot of a user, for which a standard ski binding 2 can be provided for each ski. By way of example, the ski binding 2 is made in two parts and comprises a front jaw 3 provided for hanging the toe of the shoe and an automatic heel piece 4 of the heel section of a sports shoe and / or ski can detach if necessary. The front jaw 3 and / or the automatic heel piece 4 can in this case be made in the form of a safety ski binding reducing the risk of injury to the user in the context of his skiing practice.

The ski 1 is made, in terms of shape, essentially in the manner of a board and can be called a board type winter sport device. The corresponding ski 1 comprises in this case a lower bearing structure 5 essentially in the form of a board and an upper bearing structure 6 held above which can also be produced essentially in the form of a board or plate. The upper bearing structure 6 in this case comprises with respect to the longitudinal axis of the ski 1 a length 7 corresponding at least to a longitudinal extension 8, measured in the same direction, of a mounting area 9 for a ski binding 2 to be mounted on the ski 1. The minimum length 7 of the upper bearing structure 6 is therefore at least greater than or equal to the mounting part and / or to the mounting area 9 for a ski binding 2. This makes it possible to guarantee that the ski binding 2, in particular its front jaw 3 and its automatic heel piece 4, can be fixed and / or maintained, with load transmission, on the upper bearing structure 6.

In the illustrated embodiment, the length 7 of the upper supporting structure 6 is approximately twice the longitudinal extension 8 of the mounting area 9. It seems appropriate that the upper supporting structure 6 has a length 7 greater than 50 % of a length 10 of the lower bearing structure 5. According to an advantageous measure, the front and rear longitudinal end of the upper bearing structure 6 protrudes relative to the longitudinal direction of the ski 1 beyond the mounting area 9 for a ski binding 2 which can be fixed to ski 1 and / or to be fixed to it.

The upper supporting structure 6 and the lower supporting structure 5 are fixedly and / or non-slidingly connected together. It is provided in particular, according to a practical embodiment, that the upper supporting structure 6 is connected in a durable and / or non-detachable manner to the lower supporting structure 5, in particular glued entirely flat. The lower supporting structure 5 comprises, at at least one of its longitudinal ends, a spatula section 11 extending upwards in the form of an arc. This tip section 11 supports the sliding capacity and / or the progression of the ski 1 on undulating and / or bumpy and soft and / or deep and / or on snow. First of all, the front end section of the ski 1 forms the tip section 11 with respect to the direction of forward movement - the arrow 12. If necessary, a curved and / or tip section systematically made below can be also provided with respect to the rear longitudinal end of ski 1.

The upper supporting structure 6 is provided with a plurality of transverse slots 13 extending transversely to the longitudinal direction of the ski 1. It is appropriate that these transverse slots 13 are oriented essentially at right angles to the axis longitudinal of the ski 1. One can also provide transverse slots 13 oriented obliquely to the longitudinal axis of the ski 1. The upper bearing structure 6 is in particular subdivided into at least three segments 14 by means of at least two transverse slots 13 extending transversely to the longitudinal direction of the ski 1. The segments 14 succeeding one another in the longitudinal direction of the ski 1 can in this case be arranged independently of one another or be made in the plane of the construction at least partly interconnected and / or linked. The transverse slots 13 in this case extend from the upper side 15 of the upper supporting structure 6 in the direction of the lower supporting structure 5. Depending on the depth of the transverse slots 13 from the upper side 15 in the direction of the structure lower bearing 5, the individual segments 14 are separated from each other in terms of construction and / or mechanically connected to one another in the manner of an articulated belt, via relatively narrow and / or thin connecting stays. A possible mechanical connection between the individual segments 14 can be carried out in the manner of a film hinge. A film hinge is understood to mean a relatively thin and / or narrow connecting strut between connected segments 14 of the upper bearing structure 6.

It is thus possible to make available a succession of segments 14 decoupled from each other and / or a succession of segments 14 produced in the manner of an articulated belt.

It is essential that at least one of the transverse slots 13 is disposed in the upper bearing structure 6 outside the mounting area 9 provided for a ski binding 2. A transverse slot 13 is then produced inside the mounting area 9 provided for a ski binding 2 in the event of the formation of two transverse slots 13 in the upper bearing structure 6 and an additional transverse slot 13 is provided outside the mounting area 9, in particular with respect to the longitudinal direction of the ski, in front of or behind the mounting area 9.

As best shown in Figure 1, it is appropriate that the upper supporting structure 6 is subdivided into at least ten segments 14. The upper supporting structure 6 is essentially made in the form of a plate and / or board, in this is why the individual segments 14 defined by the transverse slots 13 are also made in the form of a plate and / or block and are maintained and / or supported with load transmission on the lower bearing structure 5. These more than ten segments 14 are at the origin of an articulated and / or caterpillar type structure with articulated parts, said articulated parts being defined by the individual segments 14. First of all, in case of more than ten such segments 14, it is necessary to provide more than nine transverse slots 13 distributing and / or dividing both inside the mounting area 9 provided for a ski binding 2 and on the sections located in front of and behind this mounting area 9. The upper support structure 6 of board and / or plate type in this case presses completely flat and / or almost entirely flat with its lower side on the upper side of the lower bearing structure 5.

According to an appropriate embodiment, provision may be made for the transverse slots 13 to be positioned in such a way with respect to the longitudinal direction of the upper bearing structure 6 that the fixing screws 16, 17 placed at a certain distance from each other in the longitudinal direction of the upper bearing structure 6 and / or of the ski for the front jaw 3 of a ski binding 2 and / or that the binding screws 18, 19 placed at a certain distance from each other in the longitudinal direction of the ski 1 for the automatic heel piece 4 of this ski binding 2 can be anchored and / or are anchored in the different segments 14 of the upper bearing structure 6, as best shown in FIG. 1. The fixing screws 16 to 19 can be made in pairs with respect to the longitudinal direction of the ski, as illustrated in FIG. 1. It is however also possible that at least some of the screws attachment 16 to 19 are carried out only once and / or uniquely. This is particularly applicable with respect to the fixing screw 16 before the front jaw 3. Thereafter, all the fixing screws 16 to 19 and / or all the pairs of screws are anchored in different segments 14. This results in the the most reduced possible warping of the ski and / or a characteristic bending curve extending as homogeneously as possible and / or a characteristic bending stiffness curve in connection with the buckling loads of the ski 1. In this context, it is appropriate and practical that the segments 14 provided for screwing with a front jaw 3 and / or an automatic heel piece 4, or for screwing with the guide rails 20, 21 of a ski binding 2, have a length 22 20 cm maximum. It may in particular be appropriate for the segments 14 of the upper bearing structure 6 to have at least a length 22, inside the mounting zone 9 for a ski binding 2, less than 20 cm. The corresponding fixing screws 16, 17 and / or 18, 19 provided for the ski binding 2, in particular for the front jaw 3 and / or the automatic heel piece 4 and / or for the interacting guide rails 20, 21, are anchored in different segments 14 arranged one behind the other with respect to the longitudinal direction of the ski 1.

According to an appropriate embodiment, a viscoelastic layer 23 can be arranged between the upper supporting structure 6 and the lower supporting structure 5. This viscoelastic layer is illustrated in FIG. 2 by a relatively thick line. A thickness of this viscoelastic layer 23 is suitably between approximately 0.5 mm and 3 mm.

interrupted and / or individual segmented overlap sections

As best shown in Figure 2, it can be provided according to one embodiment that the upper supporting structure 6 is connected in a non-detachable manner, in particular glued, to the lower supporting structure 5 via the viscoelastic layer 23 disposed between. Such a viscoelastic layer 23 allows in this case a high performance and durable bonding and / or bonding of the upper bearing structure 6 and / or of its segments 14 with the lower bearing structure 5.

According to an alternative embodiment, as illustrated in FIG. 5, it can also be provided that the upper supporting structure 6 is connected and / or screwed to the lower supporting structure 5 by interposing the viscoelastic layer 23 by means of a plurality of fixing screws 24. It may also be appropriate, above all in this context, that the viscoelastic layer 23 is produced less in conduits leading to the transverse slots 13. Consequently, at least some segments 14 of the upper bearing structure 6 are maintained on the partial sections and / or associated segments, relatively small and / or adjusted in terms of surface area, of the viscoelastic layer 23. A tearable outline and / or a periphery of the individual partial sections of the viscoelastic layer 23 corresponds in this case to the essentials with a tearable outline and / or at the periphery of the segments 14 of the upper bearing structure 6 held above. As shown in the embodiment according to FIG. 2, it is also possible, as a variant, to provide that the viscoelastic layer 23 extends without interruption between the longitudinal end, front and rear, of the upper bearing structure 6 relative to the direction longitudinal of ski 1.

As always best shown in Figure 2, it may be appropriate that a depth 25 of at least some of the transverse slots 13 measured transversely to the longitudinal direction of the upper supporting structure 6 is more than 50% the height 26 of the upper supporting structure 6. In the embodiment illustrated in FIG. 2, the depth 25 of the transverse slots 13 corresponds to approximately 100% of the height 26 of the upper supporting structure 6. It can in particular be provided that a depth 25 measured transversely to the longitudinal direction of the upper supporting structure 6 of at least some of the transverse slots 13 reaches the viscoelastic layer 23 between the upper supporting structure 6 and the lower supporting structure 5. It is particularly suitable that the depth 25 of the transverse slots 13 produced inside the mounting zone 9 for a ski binding 2 has a depth 25 which can reach the viscoelastic layer 23.

It is appropriate that a width 26 measured parallel to the longitudinal direction of at least some of the transverse slots 13 is between 0.1 mm to 10 mm, preferably between 1 mm and 5 mm. As best shown in Figure 5, at least some of the transverse slots 13 are provided and / or filled at least in part with an elastomeric plastic material 27. This elastomeric plastic material 27 can serve as an elastic flexible counter-bearing and / or damping element between at least individual segments 14 of the upper bearing structure 6.

According to an alternative embodiment, as illustrated by way of example in FIG. 6, it is also possible to provide that at least some of the segments 14 of the upper bearing structure 6 rest against each other, at the unsolicited state of ski 1, without gap and abut against each other. The front ends are in particular positioned between segments 14 which are already linked in the unsolicited state of the ski 1 without gaps and / or with load transmission, as shown on the left half of FIG. 6 by way of example . In this embodiment, the segments 14 of the upper supporting structure 6 are bonded to the lower supporting structure 5 via the viscoelastic layer 23.

To guarantee that the ski 1 buckles with as little tension as possible, it may also be appropriate for a length 28 measured transversely to the longitudinal direction of the upper bearing structure 6 of at least some of the transverse slots 13 s' extends over the entire width 29 of the upper bearing structure 6 as shown diagrammatically in FIG. 1, 2.

According to an advantageous embodiment, as illustrated in FIGS. 2 to 4, it is also possible to provide that at least some of the transverse slots 13 are covered by a covering film 30. This covering film 30 prevents and / or hinders penetration of snow or ice into the transverse slots 13 enveloped and / or covered by the covering film 30. According to an appropriate measure, provision is made for the covering film 30 to be formed from plastic material and having a thickness 31 less than 0.2 mm, in particular less than 0.1 mm. This makes it possible to obtain a high form flexibility of the covering film 30 and to delay a blocking of the relative displacements between the front surfaces oriented towards each other of the transverse slots 13.

The covering film 30 can in this case wear and / or comprise a decoration and / or a graphic pattern of the ski 1. According to an appropriate embodiment, provision can be made for the covering film 30 to be produced, at least in a few sections arranged in overlap with at least some of the transverse slots 13, in a transparent or translucent manner.

Preferably, the covering film 30 forms the uppermost and / or outermost top layer 32 of the ski 1. A lower side 33 of the covering film 30 is glued, with the exception of the covering sections leading to the transverse slots 13, entirely flat with the ski 1 and / or with its upper bearing structure 6.

As best shown in Figure 2, it can be expected that the covering film 30 takes in cross section essentially the shape of an inverted U and / or is made in the form of a plug. The wall sections 34, 35 opposite to each other of the upper and lower supporting structure 6, 5 as well as the longitudinal side surfaces of the viscoelastic layer 23 are covered at least in part by the covering film 30.

As best shown in Figure 7, it can be provided that the upper bearing structure 6 has at its longitudinal ends opposite one with respect to the other a step height 36 less than 3 mm relative to the bearing structure lower 5. This guarantees in particular a relatively homogeneous and / or as continuous as possible transition between the upper and lower supporting structure 6, 5, which above all promotes robustness and / or security against the destruction of a covering film 30 As a variant, this step height 36 can also end at around zero, in particular be carried out almost continuously. One can in particular provide that at least one longitudinal end of the upper supporting structure 6 is produced so as to end in thickness dimensions and / or to extend around zero.

According to a practical measure, it can also be provided that the ski 1 according to the invention has, for a length 10 of more than 160 cm, in particular in the case of projected length 10, a maximum thickness 37 greater than 25 mm inside the zone mounting 9 for a ski binding 2, as illustrated in Figures 1 and 7 schematically. A ski 1 produced according to the present invention comprising a lower support structure 5 of board type and an upper support structure 6 held above with a plurality of transverse slots 13 is therefore relatively thick compared to what traditional and / or typical skiers practicing downhill skiing. The ski can in particular make in this section a thickness 37 of between 27 to 34 mm.

As best shown in Figure 3, it may be appropriate that the top side of the cover film 30 is selected to directly support the guide rails 20, 21 for the front and heel jaws 3, 4 of a ski binding 2 and to select a height 38 of the segments 14 in the part of the mounting area 9 for a ski binding 2 so that the fixing screws 16 to 19 are exclusively anchored in the segments 14 of the upper bearing structure 6 for the attachment of the guide rails 20, 21.

According to an alternative embodiment, as shown in FIG. 4, it can also be provided that the upper side of the covering film 30 is provided for direct spreading of the guide rails 20, 21 for the front and heel jaws 3, 4 of a ski binding 2, a length 39 of fixing screws 16 to 19 being chosen to hang the guide rails 20, 21 so that the fixing screws 16 to 19 can be anchored in the upper bearing structure 6 as well as in the lower supporting structure 5.

The lower bearing structure 5 of the ski 1 is preferably made in several layers. It may in particular comprise a sliding and / or rolling surface lining, made of plastic, an upper and / or lower strap, relevant in terms of resistance, made of metallic materials and / or made of composite materials, and at least one element of core placed between, in wood and / or plastic foam. The upper supporting structure 6 arranged above can also have a structure with several layers, as illustrated by way of example in FIG. 2. The upper supporting structure 6 can however also be produced in the form of an expanded component, injected or milled, so as to reduce the multiplicity of layers and to be able to keep the manufacturing cost as low as possible.

The exemplary embodiments indicate possible variant embodiments, knowing that it can be seen at this level that the present invention is not limited to the variant embodiments specifically illustrated thereof but that, on the contrary, that various combinations of the variants of individual realization between them are possible and that this possibility of variation is an innovative technical teaching belonging to the technical field of the skilled person.

The scope of protection is defined by the claims. The description and the drawings are however used for the interpretation of the claims. Individual characteristics or combinations of characteristics taken from the various exemplary embodiments illustrated and described may in themselves represent independent solutions according to the invention. The description explains the independent solutions according to the invention.

All the indications of ranges of values in the present description can be understood so that these any partial ranges as well as all of them are included, for example the indication from 1 to 10 must be understood so that all the partial zones starting from the lower limit 1 and up to the upper limit 10 are encompassed, that is to say that all the partial zones start with a lower limit of 1 or more and end with an upper limit of 10 or less, for example 1 to 1.7, or 3.2 to 8.1, or 5.5 to 10.

For form, it is finally mentioned that for a better understanding of the structure, elements have been illustrated in part without scaling and / or enlarged and / or reduced.
