Description

The present invention relates to a ski, in particular an alpine ski, with

  an upper and a lower base layer consisting of a plurality of thicknesses, and a core layer or core arranged therebetween, wherein the base top layer has an outer layer and the base bottom layer has a surface layer of sliding and to it are assigned, in the zone of the lateral edges of the ski, profiles which, if necessary are formed of upper edges or respectively edges respectively embedded in the upper layer and / or lower

basic.

  We already know various ski configurations which are differentiated in particular by the assembly of

  various layers and by the various pieces of structure.

  In these skis, it has been attempted, in particular in the zone of the base layers and the core layer or core, to respond to various partially contradictory conditions, such as an exact edge grip, a harmonious tension pattern, good properties of cushioning against shocks perpendicular to the sliding surface or the upper surface of the ski as well as good deformation properties when cornering. In such a ski known from CH-PS 657 276 of the same applicant, it is provided with an upper sole, a lower sole with side cheeks and a soul they surround. The core contains, beneath the connection area of the binding, a damping plate made of an elastic material, which is approximately parallel to the ski, and which passes through the side wall. As a result, shocks or impacts that act on the sliding surface of the ski are better damped because they can no longer be transmitted by the lateral cheeks to the upper surface of the ski. The tracing of tension and the deformation properties of the ski can therefore be

  still significantly improved.

  In another known ski, according to the AT PS 378 327 of the same applicant, an upper sole is spaced from a lower sole by a soul which is between them, and which extends over the entire length of the ski. The distance from the upper sole to the lower sole is variable along the length of the ski. In the area of the binding, the upper sole is further offset from the adjacent longitudinal areas of the ski in the direction of the sliding surface, i.e. the distance from the upper sole is greater. small in the area of the binding that at least a longitudinal portion of the ski defining the attachment area. In order to obtain a smooth and harmonious drawing of the tensions when the ski is urged in a direction perpendicular to the sliding surface, reinforcement layers or reinforcing gaskets are provided in addition in the zone of the binding. extend partially beyond the area of attachment in the adjacent longitudinal areas of the ski, and despite the lower thickness of the ski, it must be possible to maintain a desired moment of resistance. It was thus possible, advantageously, to reduce the distance between the contact surface of a skier and the sliding surface of the ski, but nevertheless a decoupling between the movement of the ski and the ski binding securing the ski boot. ski skiing could not be achieved by this solution. The task of the invention is to create a ski which, in its operation, allows a continuous and unobstructed deformation and thus a harmonious alignment of the tensions, in particular when passing over

  heavily hilly terrain. In addition,

  Skiing shocks from its sliding surface should be conducted only to a small extent in the area of the

ski.

  This task of the invention is solved by the fact that at the upper base layer is affected a covering layer which is connected, by force and / or form, through a support body elastically deformable, to an outer layer and / or an intermediate layer of the upper base layer which is placed between them. The surprising advantage of this solution lies in the fact that one also obtains good damping shocks acting, the sliding surface on the various areas of the ski because they are not driven, thanks to the incorporation the elastically deformable bearing body and the relative mobility thus obtained, that to a lesser extent in the ski binding area, that also a good passage in the bends by a regular deformation over the entire length of the ski. It should be added that, by the elastic change of the covering layer with the base layer, the deformation properties of the ski are further favored in the longitudinal direction, because the covering layer, normally fixed on the length of the shoe, straight and pressed against the sole

  the shoe can no longer prevent, thanks to the incorpo-

  ration of the elastic support body, the deformation of the ski, even in the zone of the fixation. By the possibility of the change in length and the relative movement between the base layer and the cover layer, the apparent shortening occurring during the bending of the ski between two points distant from each other in the longitudinal direction of the ski, because of the decrease in the size of the rope, can be simply compensated. This makes it possible to obtain a continuous ski deformation pattern corresponding to the manufacturer's idea. It is also advantageous for the covering layer to consist of several overlapping layer portions arranged one behind the other in the longitudinal direction of the ski and connected independently of one another to an outer layer and / or intermediate layer of the upper layer of based. On this occasion, it has been surprisingly found that by dividing the overlap layer into several parts and compensating in length between the overlap portion in the area of the fastener and the remaining portions of the overlayer a continuous edge grip was obtained due to the undisturbed deformation of the ski, that the guidance or steering of the ski was improved and that the pressure on the spatula when changing direction, due to a reduction compression strains in the fastening area were also reduced. By the use of several parts of the cover layer, it is possible to modify the deformation behavior of the ski by the continuous additional covering layer over the entire length of the ski. However, it is also possible to configure these other cover layer portions as spool-like transition portions to compensate for the distance in height between the additional cover layer and the base top layer and to obtain an impression. general external closed ski. But it is also possible, among other things, to equip the cover layer part close to the fastening zone with relatively soft outer layers or outer layers so that, despite the greater distance of these layers from the neutral fiber of the ski, we do not get any unwanted stiffening of the ski. Thus, it is also possible with the cover layer parts directed towards the tip or the end, considered part of the spoiler, to manufacture them in materials that do not change or little deformation behavior of the ski. Above all, a disadvantageous change in the deformation behavior of the ski can be compensated by the fact that the elastically deformable support body extends over the entire length of the cover layer or between all the cover layer parts and the layer. higher

basic, continuously.

  Selor. an alternative embodiment, it is expected that the covering layer extends only over a part of the total length of the ski, which allows to keep minimal expenditure of material for the manufacture of a ski for the purpose of useful use of

  advantages according to the invention, and additional layers

  only in the areas where they are really needed. Above all, such an achievement is also suitable for the retrofitting of a

ski already produced.

  According to another configuration, it is provided that the elastically deformable bearing body is arranged between one of the covering layer parts and the outer layer and / or an intermediate layer of the

  top layer, and that the individual parties

  dual layers of support are supported by different resiliently deformable bearing bodies, for example having different hardnesses, on the upper base layer, thus, in a simple manner, a determination of the damping behavior on the

  various areas of skiing is made possible.

  But it is also advantageous for the covering layer parts to be arranged spaced apart from one another in the longitudinal direction of the ski, so that the relative movements between the individual parts of the covering layer can take place without disturbance, and a further modification of the characteristic of damping or flexing of the ski, because of the additional layer of covering arranged at a greater distance from the

neutral fiber.

  In addition, it is also possible for the intermediate layers and / or the outer layer of the upper base layer, in particular in the connection zone of the binding, to be offset in the direction of the sliding surface coating with respect to neighboring areas. It is thus possible to avoid damage to the outer layer of the covering layer. In addition, it is possible, through these other cover layer parts, to produce a transition between the cover layer arranged at a distance above the base top layer and the base layer, for example by transitions. continuous. It is thus possible to integrate, in the design of the ski, the layer of

  covering with parts in the form of spoilers.

  According to another configuration of the ski, it is expected that the cover layer and the Plastiquement deformable support body are arranged in this offset or respectively depressed area of the base layer, so, after setting up the covering layer, one can get a shape in thickness almost unchanged compared to the traditional ski without covering layer. However, it is also advantageous for the attachment area of the fastener to be allocated additional intermediate layers extending from both sides in the area of the upper basecoat and / or

  lower. By setting up intermediate layers

  additional diaries, extending beyond the zone of fixation in the longitudinal direction, it is possible to compensate for the changing resistance by the reduction of section between the upper and lower layers of base, and

  adapt it back to the original values.

  But it is also advantageous if the outer layer of the upper base layer covers the covering layer and, where appropriate, the intermediate layers of the base top layer which are connected thereto, and are connected to it, and advantageously, that the outer layer has a zone of elastic deformation in the spaces between the

  overlap, at least in the longitudinal direction of the ski.

  It is thus possible to obtain a continuous shape or design and a unitary upper surface of the ski and if, moreover, this outer layer is provided with corresponding elastic zones of deformation in the intermediate spaces, for example, by the use of sheets of a corresponding high elasticity, a shape can be obtained that is connected even on these

intermediate spaces.

  But it is also possible that the outer layer is interrupted in the area of the intermediate spaces, which avoids destruction of the outer layer even in the case of deformations

  and extremely strong demands of the ski.

  But it is also advantageous that the part

  covering layer connected to the ski through

  diaire of the elastically deformable bearing body is arranged in the longitudinal direction of the ski between two cover layer portions connected by force bonding and / or shape to the ski or respectively to an intermediate layer of the upper base layer, because before everything, in the area of the binding or respectively in any area where there is a very high arc height during the deformation of a ski, these parts can move unimpeded vis-à-vis the remaining parts of the ski. In this embodiment, it is also more advantageously possible to compensate for the transition between the cover layer arranged above the base layer and the base top layer by continuous spoilers which may have a favorable flow effect.

  corresponding during fast speed descents.

  According to another embodiment, it is provided that one of the other cover layer portions is directly connected by force bonding and / or form to an intermediate layer of the base top layer. By the use of an elastically deformable support body it can occur, over the entire length of the ski, primarily in the area of the coupling device or the ski binding respectively, an unhindered elastic deformation and a relative movement of the sliding surface of the ski, because the lower base layer and the core, because of the high elastic displacement in the support body, can move independently and unhindered with respect to the base layer portion which is fixed in the area of the fastener. In this way, it is possible to obtain a solid and highly-resilient protection zone, in front of and behind the elastically mobile covering layer portion, which can limit a

maximum displacement.

  But it is also advantageous that the base layer portion elastically connected to the ski by the support body has a length which represents about 15% of the total length of the ski and that the front cover layer portion arranged between the tip and this lap layer portion has a length that is approximately half the length of the ski and that the rear lap layer portion extending between the lap layer portion and an end of the ski extends to about one-third of the length of the ski because, despite the configuration according to the invention, it is still possible to obtain sufficient resistance of the ski against stresses and deformations during operation in the most diverse situations. But it is also possible that the covering layer portion is formed in several thicknesses and has an outer layer and at least two intermediate layers and that, in particular between the two intermediate layers, is housed the upper edge and the deformation movement is not hindered by the upper edges and the layer part

  basic still has enough resistance.

  But it is also possible for an intermediate layer of the covering layer to be arranged over the entire length of the ski and for the support body to be arranged between this intermediate layer and the other intermediate layers of the base layer. This gives a continuous sandwich construction of the ski and therefore a continuous band of traction or compression is ensured on both sides of the core, and thus a degradation can be avoided from the soul o respectively its full function can be maintained , even in the case of a ski skirted with several parts of the covering layer. It should also be mentioned that by setting up this continuous intermediate layer, the possibility of ski

  various use cases can be easily adapted.

  It is furthermore possible that the covering layer portions arranged at a distance from each other in the longitudinal direction of the ski are of identical configuration which makes it possible to avoid, even in the case of large differences in the size of the ski. arc and the size of the rope during a deformation on a height of arc also large, impediments due to the shocks of parts of the outer layer of the base layer parts arranged the

one behind the others.

  But it is also advantageous that several overlap portions are provided, arranged at a distance from each other in the longitudinal direction of the ski, of which at least two cover layer portions extend towards each other at from the tip and the end of the ski and between these two, other parts of the covering layer are arranged which are supported on the ski by a support body and between which is provided another portion of the covering layer for thus, the magnitudes of the relative movements both in the longitudinal direction of the ski and also perpendicular to the sliding surface can be minimized and above all the area between the front jaw and the rear jaw of the coupling device, o, according to experience, the defcrmaticns are presented with the greatest height of bow, or respectively the front or rear jaw or the sole of the shoe are not hindered in their free deformation, which reduces the stress on the body elastically

  deformable support and thus extend its life.

  But it is also possible that the part of the covering layer arranged at the middle part of the ski, forming a support element for a coupling device between ski and ski boot or the other parts of the covering layer are provided with housing for fixing means of the coupling device, which allows at the same time to save the mounting accessories or respectively the support elements or the like for mounting the coupling device. But it is also possible that the housing is formed of at least one longitudinal rib running parallel to the longitudinal direction of the ski, on the side of the covering layer portion which is turned towards the core. This is advantageous because this longitudinal rib can exert a dual function and, in addition to the formation of corresponding fixing points for the coupling devices, it can also have the effect of stiffening the covering layer part which favors the operation. impeccable of a coupling device especially when it is formed

a security fastener.

  According to another configuration, it is provided that the housing for the fastening means of the coupling device is formed of a reinforcement lining extending from the other covering layer part in the direction of the core, for example of a tear-resistant synthetic material and / or wood and / or aluminum, which makes it possible to be satisfied with a minimal thickness of the covering layer portion

  receiving the coupling device.

  It is furthermore advantageous for the housing to be formed of an anchor bushing which is anchored by anchoring portions in or between the intermediate layers of the other covering layer parts. As a result, a greater thickness of the covering layer part for fastening the coupling device is only necessary if

punctually.

  It is furthermore possible that the covering layer portion provided with the housings for the coupling device has the same outer and intermediate layers as the adjacent base layer, so, in addition to a continuous configuration, the base layer portions allow also a

unitary solicitation.

  But it is also possible that the cover layer portion with the housing for the coupling device is provided with reinforcements *, reinforcing elements and / or intermediate layers so that the deformation forces necessary for triggering can be transmitted without deformation. of the cover layer. It is furthermore advantageous that the covering layer portion having the housing for the coupling device is formed in a preformed flexural-resistant part, for example, a cast aluminum part or an aluminum molded part or else a metal-plastic composite part, as the strength properties of the cover layer part can be established exactly as required with a height as low as possible of

the structure.

  According to another embodiment, it is expected that the outer layer is composed. of a synthetic resin and that the intermediate layers are formed of a carpet of fibers impregnated with resin, for example with son of coal and / or glass and / or titanium or nets or fabrics with a mesh of threads or

  respectively fibers of the same or different type.

  By the use of several fairly thin carpets with different threads, we can deal with the various

solicitations of such a ski.

  But it is also possible that the support body is formed of an elastic intermediate layer, or respectively of a carpet or several liners at a distance from each other in the longitudinal direction, of an elastically deformable material, for example rubber or a synthetic material or a foam of synthetic material or a sandwich part of various metallic or non-metallic materials, which makes it possible to reduce the total stress of the bearing bodies with respect to the size of the deformation and the like. In addition, the arrangement of such elastically deformable support cores has the advantage that in each zone where deformation occurs between the cover layer parts and the other parts of the ski, neither the snow nor the ice can penetrate and so, even with long use at low temperatures, one can maintain the properties

desired deformation.

  It is furthermore advantageous for each covering layer portion to have its own side edge portion, in particular its own upper edge, and thus the relative movement of the lap layer portions vis-à-vis the ski. is not influenced by the lateral edge parts and above all by deformations exceeding the average between these parts, degradations or tearing of such parts

  Lateral edges can also be prevented.

  Similarly, it is advantageous for each covering layer portion to have its own side cheek portion, which are advantageously connected by elastically deformable lining pieces in the region of the interspaces between the cover layer portions, in one portion. Lateral side play continues, because the parties of Lateral Play

  Configured in a staggered manner

  the deformation of the ski perpendicular to the

  sliding surface, a relatively high strength.

  However, in spite of this, it is also possible to use continuous lateral cheek portions when they have deformable parts of the lining which are in the zone of the intermediate spaces, because in this case also an irreproachable relative displacement of the parts layer layers and zones of

deformation of the ski is possible.

  According to another variant embodiment, provision is made for a width of an intermediate space arranged between the individual portions of the covering layer or for a portion divided by the number of intermediate spaces to be approximately as large as the difference between a distance of the leading edges facing each other from directly overlapping cover layer parts, both sides of another cover layer part and a length of rope between these two edges attack during deformation of the ski corresponds to a height of arc directed perpendicularly to its covering layer. As a result, the deformation movement of the ski during extremely strong bending is facilitated, since the support or outer layers of the cover layer portions can move relative to one another and thus the deformation of these support layers or external forces does not lead to any pressure build-up in the upper layer of

  recovery, acting against deformation.

  But it is also possible for several cover layer portions to be provided with housing for the coupling device and for the width of all the interspaces arranged between these cover layer portions and the other cover layer parts which are therefor adjacent to them corresponds approximately to a difference between the distance of the leading edges furthest away in the longitudinal direction of the ski and a length of rope obtained during the maximum deformation of the ski between these leading edges. By the use of several parts of the covering layer, it may be sufficient to deform less in the area of the individual parts of the covering layer and moreover, by the arrangement of the intermediate spaces or the parts of the covering layer, the deformation of the ski can be modified or respectively influenced as desired. It is moreover possible, simply with a general construction of the ski which remains the same, only by arrangement of various parts of cover layer and intermediate spaces, to adapt it to various purposes of use such as for example the descent , giant slalom, super G or special slalom because, for example, the relatively high flexibility required of a slalom ski can be achieved by a large amount of overlap parts with a basic ski construction which is otherwise identical. It is thus also possible to lower overall production prices for such skis because they can be produced in identical form, a large number of parts and be adapted, simply by the arrangement of more or less of overlay parts at the end of production, for various purposes of use. According to another embodiment, it is expected that the leading edges of directly adjacent cover layer portions essentially pass through.

  perpendicular to the side edges or respectively

  parallel to the covering layer and

  perpendicular to a median longitudinal axis of the ski.

  A regular change of position of the cover layer portions in a direction perpendicular to the sliding surface or respectively of the coating becomes

so possible.

  According to another advantageous variant embodiment, it is provided that at least one of two leading edges of directly adjacent overlapping layer portions passes obliquely with respect to the lateral edge or respectively to the median longitudinal axis. ski. This embodiment provides an additional surprising and unpredictable advantage in that in the case of internal ridges passing obliquely with respect to the lateral edge or respectivemernt the median long axis of the ski of neighboring parts of layers of covering, during the elastic deformation of the ski in a direction perpendicular to the sliding surface or respectively to the sliding surface coating and simultaneously in the case of a corresponding pressure on a lateral edge of the ski, a turning movement in the direction corresponding to the pressure is triggered or respectively supported. It is thus possible to obtain, in a simple and surprising manner, dual use of the arrangement of moving cover layer portions relatively to one another over a length of a ski, also by improving the comfort or respectively

  behavior when traveling on the ski.

  Thus, it is possible for the two leading edges of overlap portions which are directly adjacent to pass obliquely with respect to the lateral edge or respectively to the median longitudinal axis of the ski, in particular parallel to one another. to the other. By the various oblique positions of the leading edges, the behavior at the turn of the ski or respectively the support of the turn triggered by the deformation can easily be adapted to the various use cases. In addition, if the leading edges facing each other of two directly adjacent overlapping layer portions are parallel to each other, the turning movement or cornering support on the same deformation range remains

almost constant.

  According to another variant embodiment, provision is made for an elastically deformable piece of packing or an elastically deformable filling material in the space between two cover layer parts, which prevents the penetration of the snow and the ice in the displacement zone separates the individual parts of the covering layer, reliably, and despite the use of the advantages according to the invention, an optically pleasing upper surface configuration or respectively

a form of skiing is possible.

  But it is also possible that several pieces of lining, advantageously of hardness or respectively different deformation properties are arranged side by side, whereby, over the entire width of the ski, it is also possible to obtain intermediate spaces of the same width and edges attacking

  parts of the covering layer passing perpendicularly

  side edges, as well as support from the

  Turning motion in a simple way.

  It is also advantageous for the packing pieces to be configured as a damping device since it is possible to obtain a multiple function of the packing pieces. Thus, by virtue of these lining pieces, it is not only possible to keep the intermediate space empty of ice and snow to form a motion path for the relative movement of the individual parts of the covering layer, but the deformation movements can also be damped or respectively slowed in a desired manner or a shock transmission in

  the area of fixation can be decreased.

  It is also advantageous that the pieces of trim are exchangeable by means of fixing means, because the ski can be quickly adapted.

  to the various conditions of use.

  According to another configuration, provision is made for a width of the intermediate space to become increasingly narrow with the increase in the distance of the covering layer, which does not present a too great reduction in the resistance of the ski despite

  the arrangement of intermediate spaces.

  In addition, it is also possible for the outer layers of mutually adjacent overlap portions to be arranged in the region of the leading edges facing each other at different distances from the sliding surface of the ski or respectively are offset in height so that the gold. may be content with intermediate spaces of lesser width without the individual portions of cover layer or respectively higher are hampered in their relative movement in the longitudinal direction of the ski during the deformations thereof. But it is also possible that the cover layer and / or the intermediate layers of the base layer are shifted, approximately in the middle zone of the ski, the thickness of a support element forming the covering layer for a coupling device between ski and ski boot, in the direction of the sliding surface of the ski and that advantageously the upper layer is interrupted on the zone of the recess, to be able to obtain a continuous and invariable construction of the ski, while being able to to save the height of structure in the area of a portion of the covering layer arranged additionally. It is furthermore advantageous that between the individual parts of the ski covering layer there is arranged a vibration damping device, thus, regardless of the space in the spaces between the individual parts of the covering layer, it is possible to obtain damping best suited to all data of vibration movements or shocks respectively acting on the

parts of the ski.

  It is furthermore advantageous for the vibration damping device to be provided with adjustable stops in longitudinal irection of the ski for a damping element or, respectively, that, moreover, the vibration damping device is provided with a device adjustment of the damping path because, therefore, the damping characteristics of the device can be quickly

adapted to the various conditions.

  But it is also possible that the lower edge or respectively the edge of the ski is bar-shaped and is advantageously configured over the entire length of the ski which allows to obtain, over the entire length of the ski, a continuous strip of traction

  in the zones of the lateral edges of the ski.

  But it is also advantageous for the lower edge or the edge of the ski to be configured in the region of the intermediate spaces between the individual parts of the covering layer and / or in the region of the covering layer part receiving the device. as an articulated head and advantageously the lower edge is continuous over the entire length of the ski as the deformation movement between the individual parts of the covering layers is advantageously supported and, despite this, a continuous support

ski on the ground.

  According to another variant embodiment, it is provided that between the covering layer portion and the sliding surface of the ski, an apparatus is arranged

  additional cushioning of a damping device

  vibration, in particular between the lower edge or the edge and the intermediate layer arranged above in the direction of the covering layer, for example, a rubber strip, thus, the various stresses occurring during the course can be diminished by

  measurements independent of each other.

  According to another variant embodiment, it is provided that the ski-s form a pair of skis consisting of two skis, the two skis having inner edges facing each other and outer edges distant one from the other. 'other. Such a pair of skis is characterized in that between the overlap portions of the two skis having the housings for the fastening means of the coupling device and the covering layer parts extending therefrom. in the direction of the tip of the ski is arranged an intermediate space and that the end edges facing towards each other of the intermediate space pass obliquely by

  airport to the median longitudinal axis of the ski or

  in relation to the lateral edge and that a distance between the tip of the ski and the leading edge which is closest to it on the inner side of the ski is greater than on the outer side. By the arrangement of corresponding intermediate spaces and cover layer parts, it is now possible, at the end of ski manufacture, in a simple way, by the corresponding arrangement of the intermediate spaces, to produce skis. right "and" left "which, when loading an internal edge, guarantee the user support during a turn or respectively a

  change in the direction of skiing on its momentum.

  But it is furthermore advantageous that a width of the intermediate space of the inner side of the ski is greater than that of the outer side, and thus, with an increase in the flexing of the ski, the support for the turn becomes greater. But it is also possible that the distance between the end of the ski e: the leading edge which is closest to a portion of the lap layer, the inner side of the ski, is greater than the outer side and / or that a width of the intermediate space on the inner side of the ski is greater than that of the outer side, so during loads on the downhill ski, a support of the turn movement with respect to the slope is triggered. Finally, it is also possible that, in the case of several recoating layer portions, the sum of the widths of the interspaces between the individual cover layer portions is greater on the inner side than on the outer side, thereby obtaining all the deformation movement, support

  getting stronger at the turn for the user.

  The invention will be better understood and other purposes, features, details and advantages thereof

14, in plan view.

  FIGS. 1 and 2 show a ski 1, which, as can be seen, has, along its length 2, a tip 3, to an end 4, different thicknesses or different dimensions, and in the unloaded state, a prior tension 6 vis-a-vis a flat surface 7 of contact with the ground. A fastening connection zone 8 is provided approximately at the ski area adjacent to the longitudinal middle towards the end 4. In addition, the úki has an upper base layer 9, a lower base layer 10 and a 11. On the upper base layer 9 is arranged, on the opposite side to the lower base layer 10, a covering layer 12. The lower base layer 10 has a

  sliding surface coating 13.

  As best seen in FIG. 2, the base top layer 9 is composed of a plurality of cover layer portions 14, 15, 16. The cover layer portions 14-16 are separated from each other by gaps intermediate 17, at least in the area of an outer layer 18 of the ski 1 or respectively of the covering layer 12 .. The covering layer portion 16 is provided with housings 19, for example, metal trim plates or plates of synthetic material of high capacity or the like, for the fixing means of a coupling device 20 for connecting the ski 1 to a ski boot. While the various layers, in particular those of the covering layer portions 14, 15 with the upper base layer 9 as well as the lower base layer 10 with the core 11 are glued or joined by means of adhesive layers or respectively of resin or synthetic material, the cover layer portion 16 is supported on the upper base layer 9 by a elastic deformable support body 21. But in the embodiment shown, it is of course also possible that the layer 12 covers only on the connection connection zone 8, that is to say essentially on

  the length of the covering layer portion 16.

  To produce a transition to the upper base layer 9, may be arranged instead of the overlap layer portions 14, 15 configured in spoilers in this embodiment, directly on the front sides remote from each other, a spoiler portion relatively movable relative to the upper base layer 9, on the cover layer portion 16. These spoilers directed towards the tip 3 and the end A may be provided with a continuous upper layer 18 so as to get a continuous form of skiing. A possible embodiment of such a spoiler is indicated, in FIG. 1, in dotted line, at the end directed towards the covering layer portion 14. In addition, it must be indicated that it is possible, in order not to undesirably changing the deformation characteristic of the ski 1, of configuring intermediate layers or respectively outer layers 18 of the covering layer portions 14, in a direction perpendicular to the contact surface 7 and in the longitudinal direction of the ski elastically, of in such a way that the covering layer portions 14, 15 have only one optical function

  and do not change the damping characteristic too much

skiing.

  In FIGS. 3 to 8, the ski 1 is shown in section on an enlarged scale, so that the construction of the covering layer 12, the base layers 9, and the core 11 as well as the lateral edges 22, 23 be better seen. The cover layer 12 is again composed of three cover layer portions 14, 15, 16. The covering layer portion 14 extends from the ski tip 3 to the connection area of the binding 8, in which the cover layer portion 16 is arranged. The cover layer portion, however, extends from the cover layer portion 16 to the ski end 4. In the present embodiment, the cover layer portions 14-16 are of identical configuration and comprise the outer layer 18 and the intermediate layers 24, for example various thicknesses of layered fibers of synthetic material, for example coatings. threads embedded in the resin, such as a phenolic resin and the like, or nonwovens, nets or knits formed from such yarns. The wires can also be

  compose of metals, glass, and also graphite.

  As can be seen in FIG. 4, the upper edges 25 of the lateral edges 22, 23 are embedded in the intermediate layers 24 of the covering layer 12. The upper base layer 11 is also composed of several intermediate layers 24, which can be configured as previously described. The core 11 is composed of a certain amount of wooden rods 26 which are schematically indicated and which are bent and pressed together. The individual rods 26 are connected to each other by means of adhesive layers 27 or a synthetic resin. Of course, it is also possible that the core 11 is formed of a sandwich construction piece, for example consisting of various foams of synthetic material or a

  corresponding construction of aluminum or the like.

  The lower base layer 10 is composed of the sliding surface coating 13 where a groove 28 is formed as well as intermediate layers 29 arranged between it and the core 11, which may be configured in the same or similar manner as the

intermediate layers 24.

  Between the slip surface coating 13 and the intermediate layers 29 or respectively as their lateral limit, is provided as another constituent part of the lateral edges, a edge 30 of metal or other highly resistant material. In addition, it is possible for a further vibration damping, especially when taking very fast turns, with use of the edge 30, an elastically deformable damping member 31 of a damping device vibrations 32 is arranged between the intermediate layers 29 at least in the area of the edges 30 or between the edges 30 and the layer

  intermediate placed above. Intermediate layers

  24, 29 are covered, in the zone of the lateral edges 22, 23, by lateral cheeks 33, for example, made of acrylonitrile-butadiene-styrene, chloride

polyvinyl or "Teflon".

  As can also be seen from the representation of FIG. 5, the covering layer portion 16 also includes an outer layer 18 with intermediate layers 24 arranged below, where the individual upper edge 34 is embedded, which is arranged at a certain distance from the upper edge in the cover layer portions 14, 15. In addition, this cover layer portion 16 is provided with housings 19 which, for example, may also form part of an intermediate layer 35 Thus, for example, this intermediate layer 35 may be formed of a press piece made of aluminum or respectively of a piece made of aluminum die-cast iron or of a hard aluminum or steel lining. However, it is of course also possible for this intermediate layer 35 to form, with the housings formed therein, an independent piece made of high-strength synthetic macerate, or else it is also possible to integrate them into the part made of synthetic material or into a corresponding pre-impregnated sheet, that is to say, carpets prepared in advance of fibers or nets, knits or nonwovens of such high-strength fibers of metal, glass or carbon impregnated with a resin that reacts only under the effect of pressure and temperature. In such a shaped part, anchoring bolts or anchoring sleeves 36 having a rough surface for better retention in the intermediate layer 35 may be inserted as housings 19. It is possible, among other things, to give to these an internal thread and to provide a fixing screw for direct integration into the part of

covering layer 16.

  The cover layer portion 16, or respectively the intermediate layer 35 facing the core 11, is fixed movably, in particular in a direction perpendicular to the cover layer 12 (double arrow 37) and in the longitudinal direction of the ski (arrow double 38 in FIG. 3) by means of an elastically deformable body 39 on the base layer 9. The construction of the lower base layer 10 can be unchanged with respect to the construction of the base lower layer 10 in the zone covering layer portions 14, 15. In that the upper covering layer 9 is provided with recesses or respective recesses 40 in the area of the recesses 19, it is possible to maintain, even in the area of the recesses recesses 40, a corresponding elastic path between them and the core 11. However, to save the height of structure in the case of the cover layer portion 16, it is also it is possible, as shown in the figure, in the region of the left housing 19, that the elastically deformable support body 39 does not extend over the entire area between the surfaces directly adjacent to the core II and the housing 19 so that the total height of the recess 40 remains available for the relative movement of the covering layer portion 16 vis-à-vis the upper base layer 9. As is shown against in the housing area right 19, there, the elastically deformable bearing body 39 extends continuously between the recess 40 and the

housing 19.

  FIG. 6 further shows that both the upper edges 34 and also the covering layer 12 and the intermediate layers 24 recommence after the intermediate spaces 17, that is to say that they are interrupted in space intermediate 17. While the lateral cheeks 33, the core 11 and the base layers 9, 10 as well as the sliding surface coating 13 and the edges 30

are continuous.

  FIG. 7 shows, by means of a highly exaggerated deformation and extremely distorted proportions, the individual layers or thicknesses of the ski 1, the manner in which the relative position of the individual portions of the covering layer 14-16 changes mutually. Dotted.is represented the rest position of the ski 1, when it is on a flat contact surface 7. At this rest position, two leading edges 41, 42 turned towards each other parts of the covering layer 14, 15 are spaced apart by a distance 43 in the longitudinal direction of the ski 1 (double arrow 38). Thus, between the leading edges 41, 42 and the leading edges 44, É5 turned towards them, intermediate spaces 17 having a width 46, 47 are obtained. If, now, the ski is deformed from the position rest shown in point. In the operating position shown in a solid line, for example, when passing over a strongly undulating terrain or a bump track respectively, the upper and lower base layers 9, 10 separated by the core 11 act as a bending traction band respectively while the cover layer portion 16, given the pre-tension against a shoe sole 48, with the coupling device 20, does not bend so much and, depending on the stiffness of the element the support or respectively of the covering layer 12 and the elasticity of the support body 39, maintains a flat line, more or less rectilinear. The deformation of the ski 1 against this cover layer portion 16 serving as a support member and in the form of a plate results in the distance between the two leading edges 41, 42 being reduced to a length 49, a rope of the ski 1 forming an arc, because now the

  dimension 43 corresponds to an arc length 50 of the ski 1.

  This depends on a height of arc 51 occurring during the deformation between the rest position and the deformed position of the core 11. If the cover layer portion 16 could freely deform, for example, if its position plane was not maintained by the coupling device 20 in conjunction with a ski boot 52, the changes in length on the width measurements A6, 47, in the outer layer 18 or respectively the cover layer 12 would accumulate as compression stresses, which would attempt to raise the outer layer 18 away from the upper base layer 9 or the intermediate layers 24. For a correspondingly larger choice of fixing forces between the outer layer 18 and the intermediate layers 24 or respectively the base layer 9, these voltages do not

  point out that in the base layer 12.

  However, in the present case, by the arrangement of the elastically deformable bearing body 39, the changing distance 53 between the covering layer portion 16 or respectively its upper layer

  18 and the soul 11, or respectively an intermediate layer

  of the base layer 9 continues on the area of the base layer portion 16 is compensated by an elongation of the bearing body 39 in a direction perpendicular to the slip surface coating 13. At the same time as the deformation, due to the various arcing heights, there is also a longitudinal defcrmation of the bearing body 39 because the parts of the bearing body 39 which, in the rest position, overlap with the leading edges 44, 45, move relative to each other, like this

  is schematically shown in Figure 7.

  The hardness or elasticity of the support body 39, which consists of rubber or synthetic material and which can have a Shore hardness of 70 to 85 and preferably 80, is established so as to make possible a sufficient modification of thickness in the direction of the arc height 51 as well as longitudinal displacement and deformation of the base layers 9, 10 with respect to the lap layer portion 16 and, as far as possible, stability lateral guidance can be obtained without additional measures. In addition, during the deformation of the ski 1 in the arcuate position shown, the deformation movement is opposed, by the increasing elongation of the elastic bearing body 39 towards the height of arc 51 with the increase of this arc height 51, a resistance increasingly important and also, when decreasing the height of the arc 51 to the rest position shown in dotted line, damping in the reverse direction is possible. Thus, short impacts, for example applied by the lower edges or the edges to the ski, can be amortized

  vis-à-vis the covering layer portion 16.

  FIG. 8 shows that during the deformation of the support body 39 which, in this embodiment, extends only inside the lateral cheeks 33, the lateral cheeks 33 move with the upper and lower layers 9, 10 and the core 11 therefore, between the cover layer portion 16 and the upper base layer 9, the result is a space of a width 54 whose size corresponds essentially to the height of the beam 51. To prevent, in this space, during the use of the ski 1, the remains of snow and

  ice-cream are fixed, which can be a disadvantage

  deformations of the ski 1, the elastic bearing body 39 can, as shown in Figure 5, be arranged continuously up to the zone of the lateral edges 22, 23 and also between the base layer 9 and the cheeks

lateral 33.

  FIG. 9 shows an alternative embodiment in which an intermediate layer 55 of the base layer 9, which continues along the entire length of the ski, is integral in movement with the intermediate layer 24 or respectively with the covering layer 12 of the part of the covering layer 14 and the core 11. The support body 39 is supported on this intermediate layer 5 with the covering layer portion 16. Thus, also above the web 11 is obtained a laminate layer sufficiently massive that the support effect of the core 11 can be used even in one embodiment o one or more cover layer portions 16 are supported on the core 11 by means of bodies In addition, this representation shows that the intermediate spaces 17 between the covering layer parts 14, 15, 16 may be closed by gaskets 56 or an elastically deformable material of filling. The gaskets 56 or respectively fillers may for example be formed of a mass of silicone or a material having a high coefficient of elongation. But it is also possible that these linings have a corresponding hardness, for example a Shore hardness between 40 and 100 and preferably 70, so that they can be used as damping members of a device. Indeed, as can best be seen from the representation of FIG. 7, during extreme deformations of the ski, it is possible for the intermediate space 17 to be practically reduced to zero. The fitting 56 can then be used as a damping path for the deflection movements or respectively the deformation movements of the ski between the zones facing the individual portions of the covering layer 14. , 15, 16. Thus, by a corresponding choice of the hardness, and / or the elasticity of these linings 56, it is possible to oppose the deformation movement of the forward part. t of the ski between the cover layer portion 16 and the tip 3 of the ski 1, a greater resistance, for example, than to the deformation of the portion of the ski extending from the cover layer portion 16 in the end direction 4 of the ski, or vice versa. But, simultaneously, during the rise of the tip 3 of the ski 1 on a bump or respectively at the arrival of the ski 1 after a jump, the shocks conducted in the user's joints can be advantageously damped, respectively the The danger of edge errors in such situations, especially in the race, can be reduced in a surprising and advantageously unpredictable way. In spite of everything, we obtain a harmonious course of tension along the length of the ski 1 and a deformation path desired by the producer and thus a continuous grip of the edge and a support as continuous as possible of the sliding surface coating 13 on the ground, on very wavy tracks or respectively during

  passage on bumps or hollows respectively.

  Another unpredictable advantage obtained due to the configuration according to the invention of the ski 1 resides in the fact that the stresses or the danger of raising the covering layer 12 during an extreme deformation of the ski are reduced. In addition, despite the support and the distribution of the compressive forces in the cover layer 12, by the abandonment of the rigid assembly between the individual parts of the coating layer 14-16, the behavior of the deformation of the ski 1 is further improved. In FIG. 10 is shown a ski 1 whose top coating layer 12 consists of several covering layer portions 57, 58, 59, and 61, arranged one behind the other in

  longitudinal direction of the ski 1 (double arrow 38).

  While the cover layer portions 57, 58, 59 are integral in motion directly, through the intermediary of corresponding layers of glue or fastening means, the base layer 9 or respectively the core 11 of the ski 1 or respectively of the lower base layer 10, the connection between the covering layer parts 60, 61 occurs with incorporation of elastically deformable bearing bodies 62, 63. The bearing bodies 62, 63 are separated in the longitudinal (double arrow 38) by intermediate spaces 64, 65, 66, 67. In each of these intermediate spaces 64-67 can be arranged a piece of packing 56, as it is shown only in the interspaces 64, 66 to ensure clarity of the drawing. This can, as already explained with reference to the previous embodiments, consist only of a filling material, for example, silicone or correspondingly elastic material, or be configured as a damping member of a damping device. The covering layer portions 60, 61 are provided with housings 19 for fastening means of a coupling device 20 for assembling a ski boot 52 to the ski 1. The tear resistance of the means in the covering layer parts 60, 61 corresponds to the resistance values required for the various stresses, between 2500 and 4500 N. Similarly, the elastic support body 62, 63 is configured so that it can absorb if high surface charge without separation of the overlap portion 61 and the upper or lower layer of

  base 9, 10 or respectively of the ski 1.

  The aforementioned embodiment example has the advantage that the cover layer parts 57-59 can deform with the upper or lower part of the base layer 9, 10 of the ski 1 or its core 11 respectively. there is a displacement with respect to the base layers 9, 10 only in the case of the covering layer portions 60, 61. As, therefore, it is not the entire length of the ski 1, on which the shoe extends between the coupling devices 20> which is to move with respect to the web 11 of the ski, the excursion movements and the relative movements of the covering layer portions 60 , 61 opposite the diaper parts

  neighboring overlays 57, 58, 59 are also smaller.

  This follows that the width 46, 47 of the intermediate spaces can be kept small and that despite this, sufficient deformation of the ski 1 independent of the sole of the shoe or the coupling device 20 is ensured. In order not to have to transmit the high tensile loads of the coupling device 20 exclusively by the elastically deformable bearing bodies 62, 63, it is possible to connect the coupling device 20 by a traction band 68, which forms with the cover layer portions 60, 61, a support member for the ski boot 52 or the coupling devices 20, in the longitudinal direction of the ski (double boom 38) in a manner that is resistant to traction. In FIG. 11 is shown another variant embodiment of a ski 69. In this case, in the intermediate spaces 17, between the covering layer portions 14, 15, 16 arranged one behind the other in the direction longitudinally (double arrow 38) of the ski 69, lining pieces 70, 71. The coupling device 20 is fixed on a covering portion 16 for assembling the ski 69 to a

ski boot.

  In each intermediate space 17 in the form of a slot is arranged a piece of trim 70, 71 transversely to the longitudinal direction of the ski. If parts of various hardness or elasticity are used for the lining pieces 70, 71, and assuming that the lining pieces 71 have a higher elasticity or a lower hardness, the ski 69 in the area of the cover layer portions 14, 15, during a unilateral load, such as a load of the edge of the inner side 72 of the ski 1, for example, because a higher pressure is exerted on this side that the outer side 73, in the area of the cover layer portions 14, 15, which is indicated in dashed lines, tends to also deform in the direction of this inner side 72 in a directional deformation perpendicular to the upper surface. This deformation supports or respectively reduces when a corresponding load of edge, the turning movement of the skier and a depression of the ski 69 in the tip area 3 or respectively of the end 4 is decreased. Depending on the choice of the hardness of the trim pieces 70, 71, it is thus possible to strengthen or weaken this "turning effect" of the ski. Of course, it is also possible, as shown in the area of the packing piece 71, at the end of the cover layer portion 16 facing the cover layer portion 14, to provide a device for adjustment 74 with which the pre-tension of the lining piece 71 can be variously adjusted. This adjustment device 74 is formed in the present example as a corrector member by an adjustable threaded rod which is held by a locknut. But it is of course also possible to use any other desired type of adjustment devices, for example, movable corners transversely to the ski or setting snaps

  and toothed sticks, or the like.

  It should also be mentioned, only for the good shape, that for a better understanding of the deformation of a ski 69 configured according to the invention, the proportions between length of the ski and width of the ski or respectively concerning the width of the intermediate spaces and the deformation of the individual ski areas, have been greatly exaggerated or respectively

  deformed in the exemplary embodiments.

  In FIG. 12 is shown another variant embodiment of a ski 69, the leading edges 41, 42 of a covering layer portion 16 as well as the leading edges 44, 45 of the diaper portions. overlap 14, 15 have a different layout. While a leading edge 44 passes roughly perpendicular to a median longitudinal axis 75, as well as parallel to the cover layer 12, the leading edge 41 which is opposite to it also runs parallel to the covering layer. 12 of the ski 69 but nevertheless obliquely to the median longitudinal axis 75. As a result, the distance 76 from the tip 3 of the ski is identical to the inner side 72 and the outer side 73. On the other hand, the distance 77 to the inner side 72 of the ski 69 is greater than a distance 78 to the outer side of the ski. An intermediate space 17 is thus obtained which has a width 79 on the outer side and a greater width 80 on the inner side. If there is a lining piece 56 in this intermediate space 17, it has the same elasticity values or, respectively, the same hardness over the entire width of the ski 69, it happens that, due to the various thicknesses of the trim piece 56, the ski 1 is deformed more in the area of the cover layer portion 14 in the direction of the internal side 72 that in the direction of the outer side 73. It is thus possible to change the maneuverability in the turns of a ski of such a configuration depending on whether the hardness or the elasticity of the trim parts is used or that the width 80 is determined relative to the width 79 as well as taking into account an angle 8I at which the leading edge 41 passes obliquely relative to

to the median longitudinal axis 75.

  As is further shown for the leading edges 42, 45, both of them can be configured parallel to the cover layer 12 but oblique to the median longitudinal axis 75. Therefore, the distances 82 ' and respectively 82 of the leading edge 45 at the end 4 are different while the difference between the distances 76 ', 77 of the leading edge 42 is also of the same magnitude while the distances are greater, width 79 'of

  the intermediate space 17 as the distances 82 ', 82.

  But, of course, in the case of such oblique leading edges 42, 45, it is possible that the difference between the distances 82, 82 'or respectively 761, 77 is different so that the intermediate space 17

  passing obliquely to the longitudinal axis

  dinal median 75 of the ski, considering transversely

  ski 69, has a variable width.

  FIG. 13 shows another variant of a ski 69, where intermediate spaces 17, 83, 84 are provided. The upper covering layer 12 of the ski 69 is consequently divided into

  cover layer portions 57, 58, 59, 60, 61.

  As can also be seen in the figure, in the case of intermediate spaces 17, 83, 84 directed obliquely with respect to the median longitudinal axis 75 or respectively in the case of a single oblique leading edge such intermediate spaces, they pass about symmetry with respect to a center line of the ski boot (Figure 12). In the present example, the angle 81 between the intermediate spaces 83, 84 and the median longitudinal axis 75 is greater than the angle 86 between the intermediate spaces 17 or respectively the leading edges assigned to them and the median longitudinal axis 75. This results in a regular deformation along the length of the ski 69, in the direction of the height and on the sides and a better curved path, or respectively a lower resistance to the deformation in the lateral direction, that is to say -say

  transversely to the median longitudinal axis 75 of the ski.

  In addition, the deformation range of the elastic bearing bodies 62, 63 is lower because the two coupling devices 20 are accommodated on different cover layer portions 60, 61 and the cover layer portion 58 in the zone of which the greatest height of arc of the deformation of the ski presents itself, is directly integral in movement of the

base layer 9.

  But it is of course also possible that the elastically deformable bearing body 39, as shown schematically in FIG. 13 by a double dotted line, extends over the intermediate spaces 17 in the direction of the tip 3 or respectively the end 4. That is to say that the elastically deformable support body 39 could also be incorporated as a layer or continuous thickness or continue over a large part of the length of the ski 69. This layer or thickness would then allow, in all areas to change position vis-à-vis the bending line of the ski 69 because of the anchoring with the coupling device 20 or the ski boot 52, such displacement while that it could be used in other areas, where appropriate, for additional shock

perpendicular to the ski 69.

  Of course, it is also possible, in the other embodiments shown, not to arrange the elastically deformable bearing bodies only between the coating layer parts and the ski where there will be relative movements, but it is also possible to use sheets or layers or respectively elastic support body mats

deformable and continuous.

  FIGS. 14 and 15 show an embodiment of a ski 69 which has, for example, three covering layer portions 14, 15, 16, at least the

2638370;

  part of the covering layer 16 being connected by an elastically deformable bearing body 21 to the other parts of the ski 69. To make it possible, by the use of the intermediate spaces 17, a damping easy to choose and a controlled distortion of each zone of the ski 69, the coupling devices 20 or the part of. cover layer 16 could for example be provided with fasteners 87 for damping elements 88, for a vibration damping device 89, which would be supported by their other end, on the

overlapping overlays 14, 15.

  As can better be seen in FIG. 15, it is also possible to arrange two damping elements 88 between the covering layer portion 16 and the covering layer portions 14, 15, which makes it possible to obtain a mounting by three points. It is thus possible to obtain a distribution and a regular support and distribution of the forces that present damping and deformation. Moreover, it is possible, in a simple manner, to program in advance a resistance to distortion by the various hardnesses of the damping elements 88 assigned to the inner side 72 or respectively to the outer side 73 of the ski 1. Of course, it is also possible to use any other desired type of damping element 88 in place of the compression or tensile springs which are shown, for example gas springs, rubber spring elements, material blocks synthetic or

  torsion or leaf springs respectively.

  In this embodiment as well, it is of course possible that the covering layer is formed only of the covering layer portion 16 while the length positioning of the areas of the covering layer 12 or respectively of the layer portion overlap 16 extending in the opposite direction to that in the direction of the tip 3 and the end 4 of the ski, occurs by means of the vibration damping device 89. In addition, this damping device allows adjust the elastic deformation behavior and thus the deformation movement of the ski vis-à-vis the covering layer which is formed only by the layer portion of

recovery 16.

  Finally, we must point out again, only for the good order, that for a better understanding of the invention, the ski or the individual layers and thicknesses of the ski are represented strongly exaggerated as well in longitudinal extension as respectively in thickness or well deformed and without

respect the proportions.

  It is of course also possible to exchange the various individual parts of each of the exemplary embodiments, so that, for example, a vibration damping device 89 can be used for the embodiment of the ski according to FIGS. Similarly, the construction of the individual layers such as the base bottom layer 10, the base top layer 9, the core 11 may occur according to the various known embodiments of the art and the The invention is in no way limited to the construction of the layers shown in the drawings and in the exemplary embodiments. It is important for the present invention that the covering layer

* or, respectively, in the case of a layer of

  overlap consisting of several parts, that the cover layer parts arranged with the coupling device or respectively in the assembly area are connected to the ski 1 by means of elastically deformable bearing bodies, this assembly can occur on if necessary, by metal spring elements or plastic spring elements of corresponding configuration, instead of the elastic layers. In addition, it is also possible to arrange, inside the ski, in addition, corresponding damping devices such as springs, az springs or the like which are not visible from the outside and therefore do not pose no

  problem of icing or clogging by snow.

  Of course, the parts of spoilers which are directly formed on the part of the covering layer, as shown in dashed lines in FIG. 1, can also consist of a material that is itself elastically deformable so that they can be adapt without any play to the various

  deformations of the base top layer 9.

  In addition, it should be remembered, in the case of the solution according to the invention with use of cover layer 12 or respectively of parts of layer

  16 o is fixed the coupling device-

  20 for the ski boot, that by the incorporation of an elastically deformable support body, it is possible to

  prevent angular displacement of the coupling parts

  the coupling device 20 with respect to a contact surface of the ski boot 52, as shown for example in FIG. 7. In this embodiment, an angle 90 is always about 90, regardless of the deformation of the ski 1. If the cover layer 12 or respectively the cover layer portion or portions arranged in the area of the binding are configured with a lower bending resistance in a direction perpendicular to the contact surface 7 of the ski, it is still obtained that the decrease of the angle 86 due to the deformation of the covering layer 12 or respectively of the covering layer portion 16 is less than when the coupling device 20 is arranged directly. on the upper base layer 9, since part of the deformation movement or the change in the relative position of the ski 1 is compensated by the elastically deformable body 21. nsi, compared to ski and ski binding combinations used Until now, a significant improvement. Thus, in FIG. 7, the angular change of the angle 90 is indicated by the dotted line when the cover layer portion 16 is not configured to withstand bending and deforms under the effect of deformation. ski 1, at this line indicated in dashed line. We thus arrive at the smallest angle 90 indicated in dashed line. This deformation movement is weaker than when the coupling device 20 is attached directly to the upper base layer 9 of the ski 1. For a direct attachment to the ski, the angle 90 which is delimited by the angular limit 91 ( represented in double dashed line), is smaller, so we arrive at higher deformations and thus prior tensions between the

  coupling device 20 and the ski boot 52.

  As furthermore schematically shown in FIG. 12, the edge 30 may, in the region of the intermediate spaces 17, be configured as an articulated head 92 while, for example, in the neighboring areas, the edge 30 may be configured as a solid edge 93. If the edge 30 is generally configured as an articulated edge 92 or at least in the region of the intermediate spaces 17, the deformation movement or the turning movement of the ski 1, respectively, configured according to FIG. invention can still be supported. It is thus also possible that the hinged edge 92 extends over the entire length of the part

  covering layer serving as a support member.

  According to another variant embodiment, it is provided that the support body is arranged between the covering layer or an intermediate layer and another intermediate layer of the upper base layer or the core, and has a length, in the longitudinal direction. of the ski, which is larger than the length of a base layer part and that advantageously, the support body extends over the entire length of the ski, thus the danger of detachments in the extreme part of the body of support is further diminished and moreover, the manufacture of a ski can be simplified. Furthermore, the elastically deformable bearing body may also be provided in the area of the other base layer parts to obtain a desired flexure pattern or

respectively deformations.
