Description

AT 400 524 B

The invention relates to a ski, in particular alpine skiing, with an upper and a lower base layer consisting of several layers, and a core layer arranged between them, in which the upper base layer has a cover layer and the lower base layer has a tread surface and this in the region of the side edges of the ski Edge profiles are assigned, which are optionally formed by upper or driving edges embedded in the upper and / or lower base layer.

The various forms of ski have already become known, which differ in particular in the composition of the different layers and by different built-in parts. With these skis, attempts have been made, in particular in the area of the base layers and the core layer, to meet the contradicting requirements, such as exact edge grip, harmonic tension curve, good damping properties against impacts perpendicular to the running or surface of the skis, and good deformation properties when cornering.

A device for improving the steerability of skis with little effort is known from DE-A-22 59 375. For this purpose, the unloaded ski is pretensioned upward in its end regions, that is to say in the direction facing away from the running flank, so that it only lies raised at one point on the ground. This is achieved by a spring arranged on the ski, which is articulated to the ski. The space created between the spring and the ski is closed to the outside or filled with foam, which also has a damping effect. When the spring is loaded by a user, it is deformed in the direction of the support surface, whereby the articulated connection between the ski and the spring also deforms the ski more or less in the direction of the support, depending on the amount of the load. The function of the spring is disadvantageously blocked by the ski binding, which is subject to the deformation movements of the spring under load.

Another known ski construction is described in US-A-2,995,379. This ski consists of a tread surface, in which integrated running edges, continuous side cheeks and two ski cores spaced apart from one another in the transverse direction of the ski. In this embodiment, the upper belt consists of two metal layers spaced apart from one another in the vertical direction, which are connected to one another by means of an elastic rubber layer and extend over the entire length of the ski. If the ski is deformed, e.g. when driving through undulating terrain, the entire top chord and thus also the binding connection area is deformed.

Due to the ski described in FR-A-1.580.326, it is known to use a top layer, for example made of aluminum, in a ski, the serpentine or opposite side edges projecting in the direction of the opposite side edges in the longitudinal direction of the ski from each other distanced incisions is provided. By reducing the section modulus of this top layer, the elastic properties of a ski designed in this way are to be improved. It is disadvantageous that, due to the incisions of the same kind, only one-sided follow-up and a consequent cupping of the ski is achieved, which prevents the ski from being guided exactly on the support surface.

In such a known ski - according to CH-A-657 276 by the same applicant - this is provided with an upper flange, a lower flange with side cheeks and a core enclosed by them. The core contains, below the binding connection area, a damping plate made of elastic material, lying approximately parallel to the ski, which passes through the side wall. As a result, the impacts or blows acting on the tread of the ski are better damped, since they can now also not be passed on to the surface of the ski via the side cheeks. However, the tension curve and the deformation properties of the ski could not be improved significantly.

In another known ski - according to AT-B-378 327 by the same applicant - an upper flange is spaced from a lower flange by a core located between them, which extends over the entire length of the ski. The distance from the upper to the lower flange varies along the length of the ski. In the binding area, the top flange is also offset in relation to the adjacent longitudinal areas of the ski in the direction of the tread, i.e. the distance between the upper flange is smaller in the binding area than in at least one of the longitudinal areas of the ski adjacent to the binding area. In order to obtain a uniform harmonic stress curve when the ski is stressed in the direction perpendicular to the tread, additional reinforcement layers or reinforcement inserts are provided in the binding area, some of which extend beyond the binding area into the adjacent longitudinal areas of the ski, despite the reduced thickness the desired resistance moment of the ski can be maintained. This made it possible to advantageously reduce the distance between the footprint of a skier and the running surface of the ski, but a decoupling between the ski movement and the ski binding fixing the ski boot to the ski could not be achieved with this solution. 2nd

AT 400 524 B

The invention is based on the object of creating a ski that has a continuous unimpeded deformation in the ferry operation and thus a harmonic voltage curve; especially when driving through heavily copied terrain. In addition, the impact loads acting on the ski from the tread are to be transmitted to the area of the top layer of the ski only to a reduced extent.

This object of the invention is achieved in that the upper base layer is assigned a cover layer consisting of a plurality of cover layer parts arranged one behind the other in the longitudinal direction of the ski, of which cover layer parts at least the cover layer part arranged in the binding connection area or several cover layer parts via at least one elastically deformable bearing body independently of the other cover layer parts is non-positively and / or positively connected to a top and / or intermediate layer of the upper base layer arranged between this and the core. The surprising advantage of this solution is that both a good damping of the impacts on the different areas of the ski from the tread is achieved, since this is only reduced to a limited extent by the interposition of the elastically deformable bearing body and the relative mobility achieved thereby the binding area of the ski are guided, as well as good cornering is achieved by a uniform deformation over the entire length of the ski. In addition, due to the elastic change of the cover layer with the base layer, the deformation properties of the ski in the longitudinal direction are additionally favored, since the cover layer, which is normally fixed over the length of the shoe, is pressed against the sole of the shoe and is now deformed by the interposition of the elastic bearing body Ski can not hinder in the binding area. Due to the possibility of changing the length and relative movement between the support layer and the cover layer, the apparent shortening that occurs during the deflection of the ski between two points spaced in the longitudinal direction of the ski, due to the reduction in the chord dimension, can be easily compensated. This makes it possible to achieve a continuous course of deformation of the ski that corresponds to the manufacturer's ideas. It has surprisingly been found that by dividing the cover layer into several parts and the longitudinal compensation between the cover layer part in the binding area and the other cover layer parts, in addition to the now continuous edge grip, due to the trouble-free deformation of the ski, the control or steering is very improved because the blade pressure is also reduced when the direction changes due to a reduction in the compressive stress in the bond area. By using several cover layer parts, it is possible to change the deformation behavior of the ski accordingly, for example by the additional cover layer running over the entire length of the ski. On the other hand, however, it is also possible to design these additional cover layer parts only as transition parts in the manner of Spoiiers, in order to compensate for the height distance between the additional cover layer and the upper base layer, and to achieve a closed outer overall impression of the ski. However, it is also possible, among other things, to provide the cover layer parts adjacent to the binding area with relatively soft intermediate layers or cover layers, so that despite the greater distance of these layers from the neutral fiber of the ski, no undesirable stiffening of the ski is achieved. So it is also possible with the cover layer parts directed as spoiler parts in the direction of the tip or the end to be made of materials that do not change the deformation behavior of the ski, or only insignificantly. Above all, a disadvantageous change in the deformation behavior of the ski can be compensated for by the fact that the elastically deformable bearing body extends continuously over the entire length of the cover layer or between all cover layer parts and the upper base layer. Furthermore, the cost of materials for the manufacture of a ski for using the advantages according to the invention can be kept low, and additional layers can only be provided in those areas in which they are actually needed. Above all, such a version is also suitable for retrofitting an already produced ski.

According to another further development, it is provided that one of the individual cover layer parts has an elastically deformable bearing body, e.g. with a hardness of 70 to 85 Shore, preferably 80 Shore and the other cover layer parts are supported on the upper base layer by means of elastically deformable bearing bodies with different hardnesses, so that the damping adhesion can be easily adapted to the different areas of the ski.

However, it is also advantageous if the cover layer parts are arranged at a distance from one another in the longitudinal direction of the ski, since this allows the relative movements between the individual cover layer parts to run undisturbed, and an additional change in the suspension or deflection characteristics of the ski, due to the greater distance from the ski neutral fiber arranged additional top layer, is avoided. 3rd

AT 400 524 B

Furthermore, it is also possible for the intermediate layers and / or the top layer of the upper base layer, in particular in the bonding area, to be deformed in relation to the adjacent areas in the direction of the tread covering. This also prevents damage to the top layer of the top layer. Furthermore, it is possible to use these additional cover layer parts to produce a transition between the cover layer arranged at a distance above the upper base layer and the base layer, for example by means of transitions running. This means that the top layer with spoiler-like parts can be integrated into the design of the ski.

According to another design of the ski, it is provided that the cover layer part and the elastically deformable bearing body are arranged in a staggered or recessed area of the base layer, whereby an almost unchanged thickness profile can be achieved after the insertion of the cover layer compared to the conventional ski without cover layer.

However, it is also advantageous if the binding connection area is assigned additional intermediate layers in the area of the upper and / or lower base layer which protrude on both sides in the longitudinal direction of the ski. By inserting additional intermediate layers that extend beyond the bond area in the longitudinal direction, the strength that changes due to the reduction in cross-section between the upper and lower base layers can be compensated for and adapted to the original values.

However, it is also advantageous if the cover layer and, if appropriate, the intermediate layers of the cover layer connected to it cover the upper base layer and have or are interrupted in the spaces between the individual cover layer parts, at least in the longitudinal direction of the ski. As a result, a continuous design and a uniform surface of the ski can be achieved, and moreover this top layer is provided with corresponding elastic deformation areas in the spaces, e.g. by using appropriate highly elastic foils, the design can also be seamlessly guided across these gaps. As a result, damage to the top layer can also be avoided even with extremely severe deformations and stresses on the ski.

However, it is also advantageous if the cover layer part connected to the ski by means of the elastically deformable bearing body is arranged in the longitudinal direction of the ski between two cover layer parts which are connected directly to the ski or to an intermediate layer of the upper base layer in a non-positive and / or positive manner, since As a result, it can move freely in relation to the other parts of the ski, especially in the binding area or in the area in which the greatest bow height occurs when a ski is deformed. In this embodiment, it is also advantageously possible to compensate for the transition between the cover layer arranged above the base layer and the upper base layer by extending spoilers, which can result in a correspondingly favorable flow pattern when traveling at high speed.

However, it is also advantageous if the cover layer part which is elastically connected to the ski via the bearing body has a length that is approximately 15% of a total length of the ski and the front cover layer part arranged between the tip and this cover layer part has a length that is half corresponds to the length of the ski, and the rear cover layer part, which extends between the cover layer part and one end of the ski, extends over about a third of the length of the ski, since despite the design according to the invention, the ski is still sufficiently strong to withstand the stresses and deformations Ferry operation can be achieved in a wide variety of driving situations.

Furthermore, it is also possible for the cover layer part to be formed from a cover layer and at least two intermediate layers, and for the upper edges to be arranged in particular between the two intermediate layers, as a result of which the deformation movement is not impeded by the upper edges, and for the cover layer part nevertheless to have sufficient strength .

It is also possible that the top layer parts, which are spaced apart from one another in the longitudinal direction of the ski, are formed from the same top and intermediate layers, as a result of which even with large differences between the bow and chord dimensions when deformed by a correspondingly large bow height, hindrances caused by the Impact of parts of the cover layer or the intermediate layer of the cover layer parts arranged one behind the other can be avoided.

However, it is also advantageous if two further cover layer parts are arranged between at least two cover layer parts which extend towards one another from the tip and the end of the ski, each of which is supported on the ski via a bearing body and between which an additional cover layer part is provided , since this allows the size of the relative movements both in the longitudinal direction of the ski and perpendicular to the tread to be minimized, and above all that area between the toe and toe of the coupling device, in which experience has shown deformations with the greatest arc height, of the coupling device or Toe and buttocks or 4

AT 400 524 B of the shoe sole in the free deformation are not hindered, whereby the stress on the elastically deformable bearing body is reduced and thus their life can be extended considerably.

However, it is also possible that the cover layer part arranged in the central longitudinal section of the ski is designed as a supporting element for a ski binding and is provided with receptacles for fasteners of the ski-5 fertilizer, thereby additionally saving assembly aids or supporting elements or the like for mounting the coupling device can.

Furthermore, it is also possible that the receptacle by at least one longitudinal rib running parallel to the longitudinal axis of the ski, arranged on the side of the cover layer part facing the core, or by a reinforcement insert extending from the cover layer part in the direction of the core, for example from a pull-out resistant Plastic and or or wood and or or aluminum is formed. This is advantageous insofar as this longitudinal rib can perform a double function and, in addition to the arrangement of corresponding fastening points for the coupling devices, at the same time also stiffens the cover layer part, which favors the proper functioning of a coupling device, in particular if it is formed by a safety ski binding. In this way, even with a small thickness for the cover layer part receiving the coupling device, it is possible to find sufficient length.

It is also advantageous if the receptacle is formed by an anchor sleeve which is anchored via anchoring parts in or between the intermediate layers and the top layer of the cover layer part, since this only necessitates a greater thickness of the cover layer part for fastening the coupling device at certain points. 20 is.

Furthermore, it is also possible for the cover layer part provided with receptacles for the ski binding to be formed from the same cover and intermediate layers as the further cover layer parts arranged adjacent to this cover layer part, whereby, in addition to a continuous design, the cover layer parts also allow uniform stress. 25 It is also possible, however, for the cover layer part to be provided with the receptacle for the ski binding with additional reinforcing inserts and / or intermediate layers in relation to the cover layer part adjacent to it, or for it to be made of a rigid molded part, e.g. an aluminum casting or an aluminum pressed part or a metal-plastic composite part is formed, so that the deformation forces necessary for triggering can be transmitted without deformation of the base layer plate, since the strength properties of the cover layer part are tailored precisely to the requirements with the smallest possible height can be.

According to a further embodiment, it is provided that the cover layer made of a plastic resin and the intermediate layers made of resin-impregnated fiber mats, e.g. with carbon and / or glass or or titanium threads and / or nets or knitted fabrics of such identical or different types of threads or fibers are formed. By using several thin mats with different threads, the different stresses of such a ski can be met.

But it is also possible that the bearing body by an elastic intermediate layer or a mat or several longitudinally spaced insert parts made of elastically deformable material e.g. Rubber or plastic or plastic foam is formed, whereby the total stress of the 40 bearing body can be reduced with respect to the size of the deformation and the like. Furthermore, the arrangement of such elastically deformable bearing bodies has the advantage that neither snow nor ice can penetrate in the area in which a deformation takes place between the cover layer parts and the other parts of the ski, and thus maintain the desired deformation properties even after prolonged operation at low temperatures can be. It is also advantageous if each cover layer part is assigned its own side cheek, in particular its own top edge or its own part of a side cheek, which are preferably connected via elastically deformable insert parts in the area between the cover layer parts to form a continuous side cheek, since this causes the relative movement the top layer parts compared to the ski are also not influenced by parts of the side edge and, especially in the case of above-average deformations between these parts, damage or tearing out of such side edges can also be prevented. The web-like side cheek parts usually provide a relatively high resistance to the deformation of the ski perpendicular to the tread. Nevertheless, it is also possible, if necessary, to use continuous side cheek parts if they have deformable intermediate pieces which lie in the area of the intermediate spaces, since even then a correct relative adjustment of the individual cover layer parts and deformation areas of the ski is possible.

According to another embodiment variant, it is provided that a width of gaps between the end edges of the cover layer part receiving the ski binding and the mutually facing end edges of the further cover layer parts on both sides of the cover layer part receiving the ski binding

AT 400 524 B is as large as a difference between the distance of the end edges of the further cover layer parts, which are spaced apart from one another in the longitudinal direction of the ski, and a chord length that results between these end edges when the ski is deformed to the maximum. This facilitates the deformation movement of the ski in the event of extremely strong deflections, since the individual base or cover layer parts of the cover layer parts can move relative to one another, and thus the deformation of these base or cover layer parts does not lead to pressure build-up in the upper base layer, which leads to deformation counteracts. By using several cover layer parts, less deformation can be found in the area of the individual cover layer parts and, moreover, the deformation course of the ski can be changed or influenced as desired by the arrangement of the spaces or the cover layer parts. As a result, it is easily possible to adapt the overall structure of the ski by arranging different cover layer parts and gaps, for different purposes, such as downhill skiing, giant slalom, Super-G or special slalom, for example because of the greater flexibility required by a slalom ski is achieved by a plurality of cover layer parts with an otherwise identical basic structure of the ski. However, this makes it possible to reduce the production costs of such skis as a whole, since they can be produced in larger numbers in the same design and can only be adapted to the different uses by arranging more or fewer top layer parts at the end of production.

According to another embodiment it is provided that end edges of immediately adjacent cover layer parts preferably run perpendicular to the side edge or parallel to the cover layer and perpendicular to a longitudinal central axis of the ski. This enables a uniform change in the position of the cover layer parts in the direction perpendicular to the running surface or to the covering.

According to another advantageous embodiment variant, it is provided that at least one of two end edges of cover layer parts immediately adjacent to one another runs obliquely to the side edge or longitudinal central axis of the ski. This embodiment provides a surprising, unforeseeable additional advantage insofar as in the case of inner edges of adjacent cover layer parts which run obliquely to the side edge or longitudinal central axis of the ski, when the ski deflects in the direction perpendicular to the tread or tread surface, at the same time with corresponding pressure on a side edge of the ski, one Steering movement in the direction corresponding to the pressure is triggered or supported. As a result, a double benefit from the arrangement of cover layer parts that can be adjusted relative to one another and over a length of a ski can also be achieved in a surprisingly simple manner, and an improvement in the driving comfort or the driving behavior of the ski.

So it is also possible that both end edges of directly adjacent cover layer parts run obliquely to the side edge or to the longitudinal center axis of the ski, in particular parallel to one another. Because the different inclination of the front edges, the steering behavior of the skis or the steering assistance triggered during the deformation can be easily adapted to different applications. If, in addition, the mutually opposite end edges of two directly adjacent cover layer parts run parallel to one another, the steering movement or steering support remains approximately constant over the entire deformation range.

According to another embodiment variant, it is provided that an elastically deformable insert part or an elastically deformable filling compound is provided in the space between two cover layer parts, as a result of which the penetration of snow and ice in the movement area between the individual cover layer parts is reliably prevented, and despite the use of the advantages according to the invention optically appealing surface design or design of the ski is possible.

However, it is also possible for several insert parts, preferably with different hardnesses between 40 and 100 Shore, preferably 70 Shore or deformation property, to be arranged next to one another in the intermediate space transversely to the longitudinal axis of the ski, as a result of which the intermediate spaces are of equal width over the entire width of the ski and perpendicular to the side edges of the front edge of the cover layer parts, a support of the steering movement can be achieved in a simple manner.

It is also advantageous if the insert parts are designed as an additional damping device, since a multiple function of the insert parts can thereby be achieved. These insert parts not only make it possible to keep the space between ice and snow free to form a movement path for the relative movement of the individual cover layer parts to one another, but also to dampen or slow down the deformation movements to the desired extent or to transmit impacts be reduced in the bond area.

It is also advantageous if the insert parts can be exchanged by means of fastening means, since the ski can thereby be quickly adapted to different operating conditions. In another development it is provided that the width of the interspace becomes narrower as the distance from the cover layer increases, so that the strength of the ski 6 is not reduced too much

AT 400 524 B is given despite the arrangement of gaps.

Furthermore, it is also possible that the cover layers of the adjacent cover layer parts in the region of their mutually facing end edges are arranged offset from one another at different distances from the running surface of the ski or the height, as a result of which it is possible to find 5 spaces with gaps of smaller width without that the individual cover or cover layer parts are hindered in their relative movement in the longitudinal direction of the ski during deformation of the ski.

However, it is also possible for the cover layer and / or the intermediate layers of the base layer to have a different distance from the running surface of the ski over the longitudinal direction of the ski, since this allows the different stresses in the different areas to be compensated for.

Furthermore, it is also possible for the cover layer and / or the intermediate layers of the base layer to be offset, preferably in the direction of the tread of the ski, approximately in the central longitudinal section of the ski, by a thickness of a support element forming the cover layer for a bond between the ski and the ski shoe the cover layer is interrupted over the area of the depression, as a result of which a continuous, T5 constant layer structure of the ski can be achieved and, despite this, structural height can be saved in the area of an additionally arranged cover layer part.

It is furthermore advantageous if a vibration damping device is arranged between the individual cover layer parts of the ski, since, regardless of the space available in the spaces between the individual cover layer parts, a damping of the vibration movements or of the ski parts that is best adapted to the respective circumstances impacts can be achieved.

It is advantageous here if stops for a damping element are assigned to the vibration damping device in the longitudinal direction of the ski, or if the vibration damping device is also provided with an adjusting device for the damping path, since the damping characteristics of the damping device can thereby be quickly adapted to different conditions .

However, it is also possible for the lower edge or running edge of the ski to be rod-shaped and preferably continuous over the entire length of the ski, as a result of which a continuous tension band is achieved in the side edge regions of the ski over the entire length of the ski. 30 However, it is also advantageous if the lower edge or running edge of the ski is designed as a link edge in the area between the individual cover layer parts and / or in the area of the cover layer parts receiving the coupling device, and preferably the lower edge over the entire length of the ski is continuous, since this advantageously supports the deformation movement between the individual cover layer parts, and nevertheless the ski 35 is in continuous contact with the ground.

According to another embodiment variant, it is provided that between the cover layer part and the running surface of the ski, an additional damping member of a vibration damping device, in particular between the lower edges or driving edges, and the intermediate layer arranged above in the direction of the cover layer part, e.g. a rubber strip is arranged, since the different stresses occurring during the ferry operation can be reduced with mutually independent training or measures.

According to another embodiment variant, it is provided that the skis form a pair of skis consisting of two skis and that the two skis have mutually facing inner sides and outer sides facing away from each other in the side-by-side position. Such a pair of skis is characterized by the fact that an intermediate space is arranged between the cover layer parts of the two skis, which have the receptacles for the fastening means of the binding, and the cover layer parts extending from these in the direction of the tip of the ski, and the end edges that face each other obliquely run to the longitudinal center axis of the ski or to the side edge and a distance between the ski tip and the front edge closest to it is greater on the inside of the respective ski 50 than on the outside. By arranging appropriate gaps and cover layer parts, it is now possible at the end of the production of ski in a simple manner, by the corresponding arrangement of the gaps " rights " and " left " To produce skis that provide the user with steering support when the respective inner edge is loaded or whose deformation supports the ski guidance in the swing. It is also advantageous if a width of the space on the inside of the ski is larger than a width on the outside, since this increases the steering support with increasing bending of the ski. 7 ΑΤ 400 524 Β

Furthermore, it is also possible that a distance between the end of the ski and the face edge of a cover layer part closest to it on the inside of the ski is greater than a distance than on the outside and / or a width of the space on the inside of the ski is greater than a width on the outside, which automatically triggers a steering movement towards the slope when the Taischi is loaded.

Finally, it is also possible that the sum of the width of the 'gaps between the individual cover layer parts is greater on the inside than on the outside in the case of a plurality of cover layer parts, as a result of which a steadily increasing steering support for the user is achieved over the entire deformation movement.

For a better understanding of the invention, it is explained in more detail below with reference to the exemplary embodiments shown in the drawings.

15 shows the ski according to FIG. 14 in a top view.

1 and 2, a ski 1 is shown which, as can be seen, has a different thickness 5 or a different tailing over its length 2 from a tip 3 to one end 4, and a preload 6 with respect to a flat contact surface in the unloaded state 7 has. A binding connection and closing area 8 is provided approximately in an area of the ski which adjoins the longitudinal center in the direction of the end 4. Furthermore, the ski has an upper base layer 9, a lower base layer 10 and a core 11. A cover layer 12 is arranged on the upper base layer 9 on the side facing away from the lower base layer 10. The lower base layer 10 has a tread surface 13.

As can be seen better from FIG. 2, the upper cover layer 12 consists of several cover layer parts 14, 15, 16. The cover layer parts 14-16 are spaced apart from one another via spaces 17 at least in the area of a cover layer 18 of the ski 1 or the cover layer 12. The cover layer part 16 is equipped with receptacles 19, for example metal insert plates or high-strength plastic plates or the like, for fastening means of a binding 20 for connecting the ski 1 to a ski boot. While the various layers, in particular those of the cover layer parts 14, 15, are glued or foamed to the upper support layer 9 and this, and the lower support layer 10 to the core 11 via adhesive layers or resins or plastics, the cover layer part 16 is elastic deformable bearing body 21 supported on the upper support layer 9.

Of course, it is also possible in the exemplary embodiment shown that the cover layer 12 extends only over the binding connection area 8, that is to say essentially over the length of the cover layer part 16. In order to make a transition to the upper base layer 9, instead of the cover layer parts 14, 15 formed in this embodiment in a spoiler-like manner, a spoiler part that is relatively movable relative to the upper base layer 9 can be arranged on the cover layer part 16 directly on the end faces that are turned away from one another. These spoilers directed towards the tip 3 and the end 4 can be provided with a continuous cover layer 18, so that a continuous design of the ski is obtained. A possible embodiment of such a spoiler is shown in FIG. 1 at the end directed in the direction of the cover layer part 14 or 15 with dashed lines. It should also be noted that, in order not to undesirably change the deformation characteristics of the ski 1, it is possible to provide intermediate layers or cover layers 18 of the cover layer parts 14, 15 in the direction perpendicular to the contact surface 7 and in the longitudinal direction of the ski, so that the cover layer parts 14, 15 only perform an optical function and almost do not change the suspension characteristics of the ski.

3 to 8, the ski 1 is shown cut on a larger scale, so that the structure of the cover layer 12, the base layer 9, 10 and the core 11 and of side edges 22, 23 can be seen better. The cover layer 12 again consists of three cover layer parts 14, 15, 16. The cover layer part 14 extends from the tip 3 of the ski to the binding connection area 8, in which the cover layer part 16 is arranged. The cover layer part 15, however, extends after the cover layer part 16 to the end 4 of the ski. In the present exemplary embodiment, the cover layer parts 14-16 are of the same design and consist of the cover layer 18 and the intermediate layers 24, for example different layers of fibers in plastic layers, for example corresponding resins, such as phenolic resins and the like. Embedded threads or nonwovens, nets or formed from such threads Knitted. The threads can consist of metals, glass, fabrics or graphite.

As can be seen from FIG. 4, upper edges 25 of the side edges 22, 23 are embedded in the intermediate layers 24 of the cover layer 12. The upper support layer 9 also consists of several intermediate layers 24, which can be designed as described above. The core 11 consists of a plurality of schematically indicated strips 26 made of wood which are glued and pressed together. The individual strips 26 are connected to one another via adhesive layers 27 or glue layers or synthetic resins. Of course, it is also possible that the core 11 can consist of a sandwich component, for example consisting of different plastic foams or a corresponding aluminum construction or the like.

The lower base layer 10 consists of the tread surface 13, in which a running groove 28 is incorporated, and intermediate layers 29 arranged between the latter and the core 11, which intermediate layers 24 can be designed identically or similarly.

Between the tread surface 13 and the intermediate layers 29 or for their lateral delimitation, a driving edge 30 or a driving edge made of metal or another high-strength material is incorporated as a further component of the side edge. Furthermore, for additional vibration damping, especially when cornering very quickly, using the driving edge 30, it is possible for an elastically deformable damping element 31 to be provided between the intermediate layers 29 at least in the area of the driving edges 30, or between the driving edge 30 and the intermediate layer 29 arranged above it Vibration damping device 32 is arranged. The intermediate layers 24, 29 are in the region of the side edges 22, 23 by side cheeks. 33 e.g. covered in ABS, PVC or Teflon.

As can also be seen from the illustration in FIG. 5, the cover layer part 16 likewise comprises a cover layer 18 with intermediate layers 24 arranged underneath, into which a separate upper edge 34 - this is arranged at a distance from the upper edges 25 in the cover layer parts 14, 15 - is embedded. Furthermore, this cover layer part 16 is provided with receptacles 19 which, for example, can also form part of an intermediate layer 35. For example, this intermediate layer 35 can be formed from an aluminum pressed part or an aluminum die-cast part or a corresponding hard aluminum or steel insert. However, it is of course also possible for this intermediate layer 35 to form its own high-strength plastic part with the molded-on receptacles 19, or in the plastic part or a corresponding prepreg -that are prepared mats made of fibers or nets, knitted fabrics or fleeces of such high-strength fibers made of metal , Glass or carbon, which are impregnated with a resin that only reacts under the influence of pressure and temperature - are integrated. In such a molded part, anchor bolts or anchor sleeves 36 can also be incorporated as receptacles 19 with a rough surface for better adhesion in the intermediate layer 35. Among other things, it is also possible to provide these with an internal thread and the fastening screw and to integrate them directly into the cover layer part 16.

The cover layer part 16, or the intermediate layer 35 facing the core 11, is adjustable on the base layer 9 via a bearing body 39 which is elastically deformable, in particular in the direction perpendicular to the cover layer 12 - double arrow 37 - and in the longitudinal direction of the ski - double arrow 38 in FIG attached. The structure of the lower base layer 10 can be unchanged from the structure of the lower base layer 10 in the area of the cover layer parts 14, 15. Because the upper support layer 9 is provided with corresponding recesses 40 or depressions in the area of the receptacles 19, it is also possible in the 9th

AT 400 524 B

Area of the recesses 40 to maintain a corresponding spring travel between this and the core 11. However, in order to save the overall height of the cover layer part 16, it is also possible - as shown in FIG. 5 in the area of the left receptacle 19 - that the elastically deformable bearing body 39 does not extend over the entire area between the directly adjacent surfaces of the core 11 and FIG. 5 Receptacle 19 extends so that the entire height of the recess 40 is available for the relative movement of the cover layer part 16 with respect to the upper base layer 9. In contrast, as shown in the area of the receptacle 19, the elastically deformable bearing body 39 extends continuously between the recess 40 and the receptacle 19.

In Fig. 6 it is further shown that both the top edges 25 and the top layer 12 and the io intermediate layers 24 start again after the spaces 17, i.e. are interrupted in the space 17. While the side cheeks 33, the core 11 and the base layers 9, 10, as well as the tread surface 13 and the driving edges 30 pass through.

In FIG. 7, an exaggerated deformation and extremely distorted proportions of the individual layers or layers of the ski 1 show how the relative position of the individual cover layer parts 14-16 changes. The rest position of the ski 1 - when it rests on a flat contact surface 7 - is shown in dashed lines. In this rest position, two mutually facing end edges 41, 42 of the cover layer parts 14, 15 are spaced apart by an amount 43 in the longitudinal direction of the ski 1 - double arrow 38. This results in the spaces 17 with a width 46, 47 between the end edges 41, 42 and the end edges 44, 45 facing them. If the ski 1 is now deformed from the rest position shown in broken lines in 20 into the operating position drawn in full lines, for example when driving through heavily undulating terrain or a mogul slope, the upper and lower base layers 9, 10 spaced by the core 11 act as a tension or bending band, while the cover layer part 16 does not bend as much due to the tension against a shoe sole 48 with the binding 20, and depending on the rigidity of the support element or the cover layer 12 and the elasticity of the bearing body 39 one more or maintains less straight, plate-shaped course. The deformation of the ski 1 resulting from the deformation of the ski 1 relative to this plate-like cover layer part 16, which serves as a supporting element, means that the distance between the two end edges 41, 42 is reduced to a length 49, a chord of the ski 1 forming an arc of a circle , since the extent 43 now corresponds to an arc length 50 of the ski 1. This is dependent on an arc height 51 occurring at 30 of the deformation between the rest position and the deformed position of the core 11. Could the cover layer part 16 deform freely, for example if its flat position were not determined by the binding 20 in connection with a ski boot 52, the length changes in the extent of the widths 46, 47 in the cover layer 18 or layer 12 would build up as compressive stresses which would attempt to lift the cover layer 18 from the upper base layer 9 and the intermediate layers 24. With a correspondingly large selection of the fastening forces between the cover layer 18 and the intermediate layers 24 or the base layer 9, these will only be noticeable by internal stresses in the cover layer 12.

In the present case, however, the arrangement of the elastically deformable bearing body 39, the changing distance 53 between the cover layer part 16 or its cover layer 18 and the core 40 11, or an intermediate layer of the support layer 9 which is continuous over the area of the cover layer part 16 an expansion of the bearing body 39 compensated in a direction perpendicular to the tread surface 13. Simultaneously with the deformation due to the different arc height 51, there is also a longitudinal deformation of the bearing body 39, since the parts of the bearing body 39, which are in the rest position in register with the end edges 44, 45, move towards one another, as is shown schematically in FIG. 45. 7 is indicated.

The hardness or elasticity of the bearing body 39, which consist of rubber or plastic and a hardness of e.g. 70 - 85 Shore preferably 80 Shore is determined so that a sufficient change in thickness in the direction of the arch height 51, as well as a longitudinal displacement and deformation of the base layers 9, 10 relative to the cover layer part 16, and if possible without such additional measures, a sufficient Cornering stability can be obtained. In addition, when the ski 1 is deformed into the deflected position of the deformation movement shown, the increasing resistance of the elastic bearing body 39 in the direction of the arch height 51 increases as the arch height 51 increases, and on the other hand when the arch height 51 is reduced, the resistance increases Resting position shown by dashed lines, damping in the opposite direction 55 allows. As a result, short impacts that are introduced into the ski, for example via the lower edges or driving edges, can be damped with respect to the cover layer part 16.

8 shows that when the bearing body 39 is deformed, which in this exemplary embodiment only extends within the side cheeks 33, the side cheeks 33 with the upper and lower 10

AT 400 524 B

Shift the base layer 9, 10 and the core 11, so that a gap with a width 54, the size of which essentially corresponds to the arch height 51, is formed between the cover layer part 16 and the upper base layer 9. In order to prevent ice and snow residues from becoming lodged in this gap during use of the ski 1, and thus the deformations of the ski 1 can disadvantageously change, the elastic bearing body 39 can be shown in FIG. 5 as far as the region of the side edges 22, 23 and also be arranged continuously between the support layer 9 and the side cheeks 33.

FIG. 9 shows an embodiment variant in which an intermediate layer 55 of the base layer 9, which is continuous over the entire length of the ski 1, is motionally connected to the intermediate layers 24 or the cover layer 18 of the cover layer part 14 and to the core 11. The bearing body 39 with the cover layer part 16 is supported on this intermediate layer 55. As a result, a sufficiently massive laminate layer is also achieved above the core 11, so that the supporting effect of the core 11 can also be used in an embodiment in which one or more cover layer parts 16 are supported on the core 11 via elastically deformable bearing bodies 39.

In addition, this illustration also shows that the spaces 17 between the cover layer parts 14, 15, 16 can be closed with insert parts 56 or an elastically deformable filling compound. The insert parts 56 or filling compounds can be formed, for example, by a silicone compound or a material with a high expansion coefficient. However, it is also possible to form these insert parts with a corresponding hardness, for example between 40 and 100 Shore, preferably 70 Shore, as a result of which they can be used as damping members of a damping device. As can be seen best from the illustration in FIG. 7, in the event of extreme deformations of the ski, the space 17 is practically reduced to 0. This adjustment path can now be used as a damping path. The insert part 56 then simultaneously serves as a damping device for the deflection movements or the deformation movements of the ski between the regions facing the individual cover layer parts 14, 15, 16. Thus, by appropriate choice of the hardness and / or elasticity of these insert parts 56, it is possible to oppose the deformation movement of the front ski part between the cover layer part 16 and the tip 3 of the ski 1 with greater resistance than, for example, the deformation of the cover layer part 16 in the direction of the end 4 of the ski-extending ski part, or vice versa.

At the same time, however, when the tip 3 of the ski 1 ascends to a hump or when the ski 1 emerges after a jump, the blows which are passed on to the joints of the user are advantageously dampened, or the risk of edge defects in such driving situations, especially in Racing operations can be reduced in a surprisingly and unpredictably advantageous manner.

Nevertheless, over the entire length of the ski 1 there is a harmonic tension curve, and a deformation path desired by the producer and thus a continuous edge grip and a continuous contact of the tread surface 13 on the ground with very rippled or wavy slopes or when driving through humps or Troughs reached.

Another unforeseeable advantage achieved due to the configuration of the ski 1 according to the invention is that the stresses or the risk of the cover layer 12 being lifted off in the event of extreme deformation of the ski are reduced. In addition, despite the support and distribution of the compressive forces in the cover layer 12, by eliminating the rigid connection between the individual cover layer parts 14-16, the deformation behavior of the ski 1 is additionally improved.

10 shows a ski 1, the upper cover layer 12 of which consists of a plurality of cover layer parts 57, 58, 59, 60, 61 arranged one behind the other in the longitudinal direction of the ski 1 - double arrow 38. While the cover layer parts 57, 58, 59 are directly connected to the base layer 9 or the core 11 of the ski 1 or the lower base layer 10 via corresponding adhesive layers or fastening means, the cover layer parts 60, 61 are connected with the interposition of elastically deformable bearing bodies 62 , 63. The bearing bodies 62, 63 are each spaced apart from one another by spaces 64, 65, 66, 67 in the longitudinal direction - double arrow 38. In each of these intermediate spaces 64-67, an insert part 56, as shown only in the intermediate spaces 64, 66 to ensure the clarity of the drawing, can be arranged. As already explained with reference to the above exemplary embodiments, this can be formed only from filler material, for example from silicone or a correspondingly highly elastic plastic, or else as an attenuator of an attenuation device. The cover layer parts 60, 61 are each provided with receptacles 19 for fastening means of a binding 20 for connecting ski boots 52 to the ski 1. The pull-out strength of the fasteners in the cover layer parts 60, 61 corresponds to the strength values required for the different stresses, between 2500 and 4500 N. Likewise, the elastic bearing body 62, 63 is designed such that it has such a high surface load without separation of the cover layer part 61 from the upper or lower base layer 9, 10 or from the ski 1. 11

AT 400 524 B

The above-mentioned exemplary embodiment has the advantage that the cover layer parts 57-59 can deform along with the upper or lower base layer 9, 10 of the ski 1 or its core 11, while a shift relative to the base layers 9, 10 only in the cover layer parts 60 , 61 is given. Since the entire longitudinal region of the ski 1, over which the shoe extends between the bindings 20, does not have to be displaced with respect to the core 11 of the ski, the deflection movements and relative movements of the cover layer parts 60, 61 with respect to the adjacent cover layer parts 57, 58, 59 lower. The consequence of this is that the width 46, 47 of the interspaces can also be kept small, and nevertheless sufficient deformation of the ski 1, independent of the shoe sole or binding 20, is ensured. In order not to have to transmit the high tensile loads between the bindings 20 exclusively via the elastically deformable bearing bodies 62, 63, it is possible to bind the bindings 20 via a tension band 68, which together with the cover layer parts 60, 61 is a support element for the ski boot 52 or the bonds 20 forms, to connect in the longitudinal direction of the ski - double arrow 38 - tensile.

Another embodiment variant of a ski 69 is shown in FIG. In this case, insert parts 70, 71 are provided in spaces 17, between cover layer parts 14, 15, 16 arranged one behind the other in the longitudinal direction - double arrow 38 - of the ski 69. The coupling device 20 for connecting the ski 69 to a ski boot is fastened on a cover layer part 16.

In each slot-shaped intermediate space 17, an insert part 70, 71 is arranged next to one another transversely to the longitudinal direction of the ski. If those with different hardness or elasticity are used for the insert parts 70, 71 and if one assumes that the insert parts 71 have a higher elasticity or a lower hardness, the ski 69 has one in the area of the cover layer parts 14, 15 one-sided loading, i.e. a loading of the driving edges on an inner side 72 of the ski 69, for example in which a higher pressure is exerted on the driving edges than on the outer side 73, in the area of the cover layer parts 14, 15 the tendency indicated by dashed lines to move towards that Deformation running in the direction perpendicular to the surface, also to be deformed in the direction of its inside 72. This deformation supports or facilitates the steering movement of the skier with a corresponding edge load, and digging of the ski 69 in the region of the tip 3 or the end 4 is reduced. Depending on the choice of the hardness of the insert parts 70, 71, this " steering effect " of the ski are strengthened or weakened. Of course, it is also possible, as shown in the region of the insert part 71, on the end of the cover layer part 16 facing the cover layer part 14, to provide an adjusting device 74 with which the insert part 71 can be prestressed to different degrees. This adjusting device 74 is formed as an actuator in the present example by an adjustable screw spindle, which is secured with a lock nut. However, it is of course possible to use any other type of adjustment device, for example key surfaces which can be displaced transversely to the ski or adjustment catches and toothed strips, or the like. '

Just for the sake of order, it should also be pointed out that, for a better understanding of the deformation of a ski 69 designed according to the invention, the relationships between ski length and ski width, or with regard to the width of the gaps and the deformation of the individual ski areas, in the exemplary embodiments shown are greatly exaggerated or were shown distorted.

FIG. 12 shows another embodiment variant of a ski 69 in which end edges 41, 42 of a cover layer part 16 and end edges 44, 45 of cover layer parts 14, 15 run differently. While an end edge 44 runs approximately perpendicular to a longitudinal center axis 75 and parallel to the cover layer 12, the opposite end edge 41 also runs parallel to the cover layer 12 of the ski 69, but obliquely to the longitudinal center axis 75. This results in a distance 76 from the tip 3 of the ski on the inside 72 as well as on the outside 73 the same. In contrast, a distance 77 on the inside 72 of the ski 69 is greater than a distance 78 on the outside 73 of the ski. This results in an intermediate space 17 which has a width 79 on the outside and a larger width 80 on the inside. If an insert part 56 is now arranged in this intermediate space 17, which has the same elasticity values or the same hardness over the entire width of the ski 69, the different densities of the insert part 56 will result in the ski 69 being in the region of the The cover layer part 14 is deformed more in the direction of the inner side 72 than in the direction of the outer side 73. This means that, depending on the use of the hardness or the elasticity of the insert parts, the ability to negotiate curves in this way can also be adjusted by adjusting the width 80 in relation to the width 79 , and with reference to an angle 81 at which the leading edge 41 extends obliquely to the longitudinal central axis 75.

As is further shown on the basis of the end edges 42, 45, both can be designed to run parallel to the cover layer 12, but obliquely to the longitudinal central axis 75. For this purpose, a distance 76 or 82 of the end edge 45 from the end 4 is of different sizes, while the difference between distances 77, 78 of FIG

AT 400 524 B

Front edges 42 is also the same size, but the distances are greater by the width 79 of the intermediate space 17 than the distances 76, 82. Of course, it is also possible with such oblique end edges 42, 45 that the difference between the distances 77, 82 and 78, 76 is different, so that the space 17, which is diagonally to the longitudinal central axis 75, is viewed transversely to the ski 69, one has different widths.

Another embodiment variant of a ski 69 is shown in FIG. 13, in which spaces 17, 83, 84 are provided. The upper cover layer 12 of the ski 69 is therefore divided into cover layer parts 57, 58, 59, 60, 61. As can also be seen in the illustration, in the case of spaces 17, 83, 84 which are oriented obliquely to the longitudinal center axis 75, or in the case of only one oblique side edge of such spaces, these spaces are approximately symmetrical with respect to a ski shoe center line 85 - FIG. 12 -. Accordingly, in the present example, angles 81 between the spaces 83, 84 and the longitudinal central axis 75 are greater than the angle 86 between the spaces 17, or the end edges assigned to them and the longitudinal central axis 75. This results in a uniform deformation over the longitudinal course of the ski 69 in Height and lateral direction, and a better cornering or a lower resistance to deformation in the lateral direction, ie reached transversely to the longitudinal central axis 75 of the ski. Furthermore, the deformation range of the elastic bearing bodies 62, 63 is smaller, since the two bonds 20 are arranged on different cover layer parts 60, 61 and that cover layer part 58, in the area in which the greatest arc height of the deformation of the ski occurs, is directly connected to the movement of the support layer 9 .

Of course, however, it is also possible for the elastically deformable bearing bodies 62, 63, as indicated schematically in FIG. 13 by dash-and-dot lines, to extend over the spaces 17 in the direction of the tip 3 or the end 4. I.e. the elastically deformable bearing body 62, 63 could also be installed as a continuous layer or layer or over a large part of the length of the ski 69. This would then allow this adjustment in those areas which have to change their position in relation to the bending line of the ski 69, due to their anchoring with the binding 20 or the ski shoes 52, while in the remaining areas, if necessary, for additional damping from perpendicular to the ski 69 impacts can serve.

Of course, in the other exemplary embodiments shown, it is also possible not only to arrange the elastically deformable bearing body between that base layer part and the ski between which there are relative movements, but continuous elastically deformable bearing body foils or layers or mats can also be used.

14 and 15 show an embodiment of a ski 69 which has, for example, three cover layer parts 14, 15, 16, at least the cover layer part 16 being connected to the other parts of the ski 69 via an elastically deformable bearing body 21. In order to enable easily selectable damping and controlled twisting of the individual areas of the ski 69 using the spaces 17, the bindings 20 or the cover layer part 16 can be provided, for example, with holders 87 for damping elements 88, for a vibration damping device 89, each with their own other end are supported on the adjacent cover layer parts 14, 15.

As can now be seen better from FIG. 15, it is also possible to arrange two damping elements 88 between the cover layer part 16 and the cover layer parts 14, 15, as a result of which a three-point mounting is achieved. This enables a uniform distribution and support and distribution of the damping and deformation forces that occur. In addition, this makes it possible in a simple manner to pre-program a torsional stiffness by means of different hardnesses of the damping elements 88 assigned to the respective inner side 72 or outer side 73 of the ski 69.

Of course, it is also possible to use any other type of damping element 88 instead of the compression or tension springs shown, e.g. Use gas springs, rubber spring elements, plastic blocks or torsion or leaf springs.

Also in this embodiment example, it is of course possible that the cover layer is formed only by the cover layer part 16, while the longitudinal positioning of the cover layer 12 or the cover layer part 16 relative to the areas extending in the direction of the tip 3 and the end 4 of the ski with of the vibration damping device 89. In addition, the suspension behavior, and thus the deformation movement of the ski relative to the cover layer formed only by the cover layer part 16, can also be set with this damping device.

Just for the sake of order, it should be pointed out again at the end that, for a better understanding of the invention, the skis, or the individual layers and layers of the skis, are often greatly exaggerated or distorted and disproportionately, both in their longitudinal extent or in their thickness .

In addition, it is of course also possible to exchange different individual parts of the individual exemplary embodiments with one another, so that, for example, a vibration damper

Claims (42)

AT 400 524 B tion device 89 can be used in the embodiment of the ski according to FIGS. 1 to 8 or 9 to 12. Likewise, the structure of the individual layers, such as the lower base layer 10, the upper base layer 9, the core 11, can be carried out in accordance with the most varied of embodiments known from the prior art, and the invention is in no way limited to the layer structures shown in the drawings and 5 exemplary embodiments . It is essential for the present invention that the cover layer or, in the case of cover layer consisting of several cover layer parts, the cover layer parts arranged with the coupling device or in the binding area are connected to the ski 1.69 via elastically deformable bearing bodies, this connection optionally being used instead of the elastic one Layers can also be formed using appropriately trained metal spring elements or plastic elements. Furthermore, it is also possible to arrange corresponding damping devices, such as springs, gas springs or the like, in the interior of the ski, which are not visible from the outside, so that no problems with icing or by stuffing with snow arise. Of course, the spoiler parts formed directly on the cover layer part, as shown in FIG. 1 with dashed lines, can also consist of an inherently elastically deformable material, so that they can adapt to the different deformations of the upper base layer 9 without play. In addition to the solution according to the invention using cover layers 12 or cover layer parts 16, on which the coupling device 20 for ski shoes is fastened, it should be noted that by interposing an elastically deformable support body, an angular displacement of the coupling parts of the coupling device 20 relative to a contact surface of the ski shoes 52, as shown for example in Fig. 7, can be prevented at all. In this embodiment, regardless of the deformation of the ski 1, an angle 90 is always approximately 90 degrees. If the cover layer 12 or the cover layer part arranged in the binding region, or the cover layer parts with a lower bending stiffness in the direction perpendicular to the contact surface 7 of the ski, it is nevertheless achieved that the reduction of the angle 90 due to the deformation of the cover layer 12 or the 25 cover layer part 16 is less than if the coupling device 20 is arranged directly on the upper support layer 9, since part of the deformation movement or the change in the relative position of the ski 1 is compensated for by the elastically deformable bearing body 39. As a result, a considerable improvement is achieved compared to the ski and ski binding combinations previously used. For example, the change in angle of the angle 90 was drawn in with dash-dotted lines in FIG. 7 if the top layer part 16 was not designed to be resistant to bending and deformed into the position indicated by dash-dotted lines as a result of the deformation of the ski 1. This results in the reduced angle 90 indicated by the dash-dotted line. This deformation movement is therefore less than if the coupling device 20 were directly attached to the upper support layer 9 of the ski 1. When attached directly to the ski, the angle 90, which is delimited by the angle-limiting end 91 - shown by two-dotted lines 35 - would be smaller, so that there would be greater canting and thus tension between the binding 20 and the ski boot 52. As further indicated schematically in FIG. 12, the driving edge 30 can be designed as a link edge 92 in the area of the intermediate spaces 17, while the driving edge 30 can be designed as a full edge 93 in the adjacent areas, for example. If the driving edge 30 is designed as a whole as a link edge 92 40 or at least in the region of the intermediate spaces 17, the deformation movement or the steering movement of the ski 69 designed according to the invention can be additionally supported. For example, it is also possible for the link edge 92 to extend over the length of the cover layer part serving as a supporting element. 45 claims 1.
