Definitions

  • the invention relates to a covering for a ski for changing snow conditions, in particular for a ski for off-road or.
  • Cross-country skiing according to the preamble of claim 1, and to a method for its production.
  • the invention also relates to a ski for changing snow conditions, in particular to cross-country or cross-country skis, the bottom sliding surfaces (17, 18) of which are made of polyethylene or another material are coated with a sufficiently small coefficient of sliding friction and in which the central region (13) of the sliding base which comes into contact with the snow during the push-off phase is formed with an elastically behaving material to form a holding base (20) or adhesive coating.
  • ski for cross-country or cross-country skiing, i.e. the sticking and sliding function are based on the fact that the sticking or resting friction between the ski floor surface and snow is large and the sliding or moving friction is small. If this condition is met, you can push off your skis and slide well.
  • snow essentially contributes to the creation of favorable friction properties for the adhesive and gliding properties of the ski.
  • the state of the snow changes with the change in temperature and age of the snow crystal, which is why, as is known, off-road or cross-country skis had to be waxed; A layer of a certain wax-like material had to be drawn over the surface of the ski, which was suitable for achieving the friction properties desired for the prevailing snow conditions.
  • the static or static friction between snow and ski depends primarily on the crystal shape of the snow. It is known that the.
  • the crystal shape of the snow changes depending on the age of the snow crystal, the snow temperature and the humidity.
  • the snow crystal has numerous different shapes, but the sharpness of the crystal tips is essential in this context.
  • Fresh snow that has fallen during frost has very sharp tips and a fine distribution. As the snow ages, the crystals grow together with their tips blunt.
  • Crystalline water forms a film on the ski tread. This influence prevents the crystals from coming into direct contact with the base material or the surface of the ski, the water film acting as an anti-friction lubricant.
  • the snow conditions can change very quickly, so that adhesion and / or gliding properties e.g. can deteriorate significantly during a competition, for example.
  • a disadvantage of waxed ski surfaces is that the waxing agents can be used up quickly under certain conditions.
  • ski floor surface or ski surface could be created that has both good sliding and good holding or adhesive properties in changing snow conditions.
  • the creation of such a ski base is the main object of the present invention.
  • the function of the ski waxes is based on the fact that the sharp tips of the snow crystals penetrate into the elastic or plastic surface layer formed by the waxing agents and thereby generate a sufficiently large amount of static or static friction which gives the ski its holding power.
  • the ski slides mainly on a thin film of water by melting the tips of the snow crystals under the influence of kinetic friction.
  • ski flooring or topping which are composed of active and passive parts which penetrate into the snow and bring about a mechanical hold.
  • a ski base is known, the surface of which is profiled in the form of a scale.
  • the scales form sloping planes on which the skis slide.
  • the vertical steps of the scales which are directed to the rear, prevent them from sliding backwards and guide them by piling up the snow in front of them.
  • a cavity and step floor or covering is also known, the function of which is based on the same mechanism as that of the scale covering, but the profile is negative.
  • the gliding behavior is better with this floor, but the holding or adherence is worse than with the scale covering.
  • NO-AS No. 89238 As an example of this solution, reference is made to NO-AS No. 89238.
  • Various hairy ski floors or toppings are also known, in which e.g. synthetic hair strips are attached, the hair is slanted in the direction of sliding. With these floors, a movement directed against the hair creates the holding or sticking of the ski during the push-off process.
  • Ski floors or coverings or treads are also known, in which smooth plastics, e.g. Teflon, for which a very small coefficient of friction is characteristic.
  • smooth plastics e.g. Teflon
  • U.S. Patent No. 2,908,506 See U.S. Patent No. 2,908,506.
  • the stopping problem is not solved with these skis.
  • ski coverings are known, in which attempts have been made to improve the inherently poor adhesion for wax materials for many plastic coverings.
  • US Pat. No. 3,897,074 corresponding to FI Patent No. 43401
  • a textile fabric is used as the ski floor material, the fibers of which extend at least to the interface of the sliding surface of the ski floor.
  • the main task of this solution is to achieve good adhesion of the ski wax to the sliding surface with the help of the fibers.
  • This sliding floor also has certain disadvantages, which are that the production of the sliding floor is difficult and the fibers wear out and break off quickly.
  • the invention has for its object to provide a ski floor or base that has both good holding and gliding properties even in changing snow conditions. Another object is to provide a simple method for producing such a covering.
  • the covering according to the invention and the manufacturing method can be used in particular for a ski which has an adhesive coating only in the central region of the ski running surface, but otherwise has bottom surfaces which have a very small coefficient of sliding friction.
  • a ski covering is created, the covering material of which consists of at least two mechanically different covering components.
  • One covering component forms the soft, elastic matrix of the covering. Whose viscoelasticity is chosen so that the snow crystals or ice pellets in cold snow, powder snow or on coarsely crystalline) eisigern snow in the soft, elastically behaving component can penetrate to a sufficiently strong links between the Skibe - lay and secure the underground .
  • the other covering component is more and more effective when the snow gets wet.
  • the water layer that occurs or forms between the ski and the ground in wet snow which then acts as a kind of lubricant and greatly reduces the ability of the ski to be pushed off or adhered to, is penetrated by the particles protruding from the soft base component.
  • the particles are hard and / or stiff enough to press into the snow through the water layer. In this way, a high static friction between the ski and the ground can be achieved even under these conditions, because the snow is very firm even in this case and the few hard particle tips in the ski base provide a good grip between the snow crystals hold.
  • the ski base according to the invention therefore works extremely effectively in all snow conditions.
  • the particles forming the further covering component can be shaped differently, fibers, spherical bodies, granular bodies or crystals being able to be used. It is important that they are designed so that they can be extracted from the finished, e.g. Stand out the finished ski base in the form of stiff tips, grains or fibers. This is achieved, for example, in that the particle materials are matched to the material of the soft, elastically behaving covering component in such a way that a good mutual anchoring of the covering components is ensured.
  • the softer covering component is primarily or mainly removed and the particles contained in the covering material form the stiff peaks or similar bodies protruding from the ski covering during this process, but remain firmly in place the soft and elastic rubber components.
  • a preferred development of the ski base results from the features of subclaim 2.
  • fibers are mixed into the base material, which fibers are made to grind out of the base tread by grinding or another similar processing method. With these fibers a hairy surface is thus produced in the middle part of the ski tread, the favorable properties of which in turn are based on the free ends of these fibers destroying the water film formed from the water of the snow crystal surface under the ski tread; thereby achieved that the crystals come into direct contact with the elastically behaving covering material of the ski in such a way that there is sufficient rest friction with regard to the adherence or holding power of the ski.
  • Peaks protruding from the sliding surface can advantageously also be produced if the particles are rod-shaped or granular.
  • the soft, elastic material of the covering advantageously consists of at least one elastomer.
  • the covering component consisting of the elastomers, polyurethane, a suitable rubber mixture, modified epoxy resin, polyvinyl chloride (PVC) or similar elastomers or a mixture of several such elastomers is preferably used.
  • PVC polyvinyl chloride
  • the hardness of the covering component formed by the elastomer or the elastomer mixture should be chosen so that it increases relatively sharply with falling temperatures. This has a very advantageous effect on the optimization of the sliding properties, since the snow crystals become harder and sharper at lower temperatures.
  • ski wax which is selected depending on the snow structure and temperature. It is generally known that the effect of the waxes is based on the tips of the snow crystals penetrating into the plastically behaving wax layer and thereby causing the friction required in the impression phase. Since the wax layer is softer than the ground itself, it also tends to weaken the glide of the ski, which is why the skier must always make the right compromise between holding and gliding. The function of the wax could be significantly promoted by the correct design and the shape of the ski's pretension or curvature, with which the aim is to influence the surface pressure between the ski and snow in different phases of diagonal step skiing.
  • Phase 1 ⁇ push-off The entire weight of the skier lies fully on the ball of the push-off leg 12. In addition to the pressure force, the push-off force generated by the muscles is effective, which can be 1.5 to 3 times the pressure force. The total effect of these forces results in the surface pressure, which is greatest under the repulsion point and decreases quite steeply in both directions (curve shown in dashed lines in FIGS. 1 and 2 (phase 1)).
  • Phase 2 ⁇ glide The entire weight of the skier is entirely on the moving leg, evenly distributed on the heel and ball of the foot. The point of action of the force shifts about 1/3 of the foot length from the previous phase to the rear end of the ski.
  • the surface pressure between ski and snow changes significantly when the parabolic vertex is detached from the base and the pressure is distributed over two vertices that lie on both sides of the leg 12.
  • the curve representing the distribution of the surface pressure ) shown in full line in FIG. 1 corresponds to the cross line curve according to FIG. 2.
  • the dashed curve according to FIG. 2 represents the surface pressure in comparison with the cross line curve for the case when a stiffer ski or a lighter skier can be considered.
  • Phase 3 downhill: the weight of the skier is even on both skis. The pressure is distributed as in phase 2, so that both skis can only be loaded by half the weight of the skier.
  • the curve marked with a dash in FIG. 1 corresponds to the curve shown in dashed lines in phase 3 of FIG. 2.
  • the curve marked with a slash corresponds to a situation in which the ski is more elastic or the skier is heavier.
  • the sliding friction coefficient on the support and rear part 17, 18 of the sliding surface of the ski is important for the sliding of the ski and that the coefficient of static friction in the central part 13 of the ski is important for maintaining it.
  • the ski 10 is a layered plate construction and its load-bearing parts consist of a cover plate 14 and a base plate and a rigid foam core 15 located between them, which has harder side parts 16 which arise in the molding phase.
  • the tip and the rear part 17 and 18 of the sliding base of the ski 10 are coated with only lubricity-producing polyethylene plastic or the like, and the central part 13 of the ski is coated with a bottom part 21 according to the invention which generates a holding capacity.
  • the sliding base of the ski can be completely coated with the base material plate 20 according to the invention.
  • composition of the floor panel material Two non-limiting examples of the composition of the floor panel material are described below.
  • polyamide fibers with a diameter of 10 ... 20 ⁇ , length 0.5 ... 1.0 mm, 80% by weight of polyurethane latex.
  • FIG. 4 shows a 100-fold enlargement of a floor material 20 produced according to Example 1 described above, the elastomer component of which is designated by reference numeral 24.
  • the surface 21 'of the floor material plate 20 is flat.
  • the surface 21 'of the base material plate 20 is ground either before casting the ski or before fixing it to the ski base or after casting the ski or after fixing the base with a grinding wheel or a belt grinder of suitable coarseness or in a corresponding manner.
  • this grinding phase some of the fibers in the elastomer component 24 emerge as free fibers 23, which are attached to the elastomer component 24 with their roots 23 ′.
  • a hairy fiber surface 21 is achieved, which the in Fig. 5 schematically resembles.
  • part of the fibers located on the surface 25 is completely separated or torn off. These torn-off fibers are designated by reference number 26.
  • a hair surface 21 which is sufficiently durable and sufficiently dense for the purpose of the invention is achieved.
  • the main function of this hair surface is that the fibers 24 destroy the water film which forms on the base material of the ski, and therefore sufficient contact of the snow crystals with the elastically behaving base material is achieved with regard to holding.
  • the fibers 23 align to a certain extent with the line in the direction of skiing and the fibers 23 can have a certain mechanical holding effect.
  • the most advantageous thickness of the fibers 22 was a range between approximately 5 and 100 ⁇ m, expediently between 10 and 20 ⁇ m.
  • the appropriate amount of the healing fibers remaining on the surface 25 in the grinding phase was determined to be approximately 2 to 100 pieces / mm 2, suitably approximately 10 pieces / mm.
  • polyamide fibers and / or other corresponding fibers are used, which are of such a type that they anchor themselves on an elastomer component 24, tolerate the manufacturing temperatures of the base plate component and are mechanically sufficiently durable and tough.
  • the material or the material combination of the elastomer component 24 is selected so that the holding effect of the sliding base of the middle part 13 of the ski is based on the elasticity of this base part in such a way that the tips of the snow crystals in the repulsion phase (FIG. 2, phase 2) are sufficiently deep can penetrate the surface plane of the floor, so that small depressions are formed in the floor 20 '.
  • the material for the elastomer component is selected so that its hardness increases as the temperature decreases.
  • a typical example of this is an elastic combination material flooring or covering, the hardness of which is approx. 50 SHORE D at a temperature of -20 ° C and approx. 40 SHORE D at a temperature of 0 ° C, and the hardness as the temperature increases decreases substantially linearly within the temperature range generally used in skiing. 6 shows the course of the hardness of the elastomer component over the temperature.
  • FIG. 7 shows the operating behavior of the ski covering material or ski coverings according to the invention in the entire temperature range of use of the ski.
  • the abscissa shows the temperature of the snow and the ordinate the static friction.
  • the solid line represents the overall static friction of the ski base.
  • the elastomer component dashed curve
  • the fibers contribute to this overall static friction, so that the solid line is created by superimposing the other two curves. It can be seen that the fibers at low temperatures - due to the greater hardness of the elastomer component present there - make only a small contribution to increasing the friction that however, they become increasingly effective in the vicinity of the freezing point and virtually compensate for the drop in the static friction curve of the elastomer component by now sticking out more effectively from the softening elastomer component. With this interaction of the base components, an essentially constant push-off adhesion or holding capacity of the base can be achieved in the entire operating temperature range of the ski.
  • the hairy surface 21 formed from the fibers also has a destructive effect on the water film in the manner described above, the elasticity-holding effect of the surface 25 being achieved.
  • the effect of the fibers 23 is particularly important when the water content of the snow is high. A sufficient holding effect at frost temperatures would also be achieved without fibers 23 by means of suitable elastomers, but in watery snow conditions the holding of the ski can be significantly improved by the hair-ground sliding base 20 according to the invention.
  • FIGS. 8 and 9 show further embodiments of the ski base.
  • no fibers, but rod-shaped particles 28 or granular bodies 29 are embedded in the covering component 24 formed by the elastomer or the elastomer mixture.
  • the particles 28 and 29 are in turn formed by solid bodies.
  • the covering consisting of the soft covering component (elastomer component) and the particle covering component can also be cast as a plate. These covering plates are then cut and used in the middle area of the ski tread. When finished, the adhesive covering is then finished. Through this endbear processing is primarily removed the elastomer component, so that the harder particles with the sections 30 and 31 protrude from the surface 25 of the surface.
  • the particles 28 and 29 remain firmly anchored with the root sections 28 'and 29' in the elastomer component 24.
  • the particles 28 and 29 can also be subjected to a change in shape.
  • the finishing of the ski covering plate in this way also results in a hairy or rough top surface 21 in this case, which, when the snow becomes wet, the water that forms between the ski covering and the ground. can destroy film layer.
  • the soft, elastically behaving ski covering component can also consist of polyethylene or of PVA (polyvinyl alcohol or vinal) or of mixtures of these materials with the components described above.
  • the harder particles can also be present in the form of spheres in the elastomer component. Particle crystals can also be used.
  • the hardness of the elastomer component is, for example, at room temperature in the range between 60 and 80 Shore D and preferably increases with a predetermined course as the temperature decreases.
  • the invention thus creates a tread or a covering material and a covering for a cross-country or cross-country ski for changing snow conditions, which as Climbing aid can be used in the central area of the ski tread.
  • the covering (20) consists of an elastic, soft material and also contains a harder particle component. Some of these harder particles are designed so that they stick out of the bottom surface of the ski base, which is done, for example, by grinding the surface of the ski base plate provided as the bottom surface in such a way that a hairy blanket forms on the ground surface, in which the protruding particles with their Roots are attached to the elastomer component.
  • the invention also provides a method for producing the base material and the ski base as well as a ski for changing snow conditions, in which the base material according to the invention is used.
