Definitions

  • the invention relates to an outsole covering for skis according to the preamble of claim 1, and a method for its production.
  • AT-PS 291 063 discloses a step arrangement in which transversely arranged rows of steps with arc-shaped edges are provided, the individual arc sections directly adjoining one another, and rows arranged one behind the other are preferably offset laterally by half the step width.
  • This arrangement has the disadvantage that acute-angled corners are formed between the arcuate sections, in which snow and ice can accumulate, so that the ability to repel decreases accordingly.
  • a guide against slipping sideways is available, but only as long as the mentioned corners between the arched sections do not fill with snow.
  • DE-OS 29 27 756 discloses a step arrangement, the step edges of which are rectilinear, perpendicular to the direction of repulsion, and the gently rising step flanks of concave or convex lateral surface sections of overlapping rotating surfaces are formed. This arrangement has no acute-angled intersections in which snow could get stuck. In addition, the resulting wavy cross profile also offers sufficient lateral guidance. However, since the gently rising step ramps are sections of rotation surfaces, all sliding surfaces are curved in the transverse direction and therefore do not offer an optimal support on the track. This manifests itself in a deterioration in the sliding behavior, especially on soft tracks. In addition, it leads to uneven wear, since projecting surface parts are present even with very flat curvatures or intersections.
  • CH-PS 189 690 discloses a ski with a tread surface which, as a repulsion aid, has an arrangement of impressed, parallelogram-shaped fields which are delimited by two intersecting sheets of parallel edges which are arranged at an angle of less than 90 ° to the longitudinal axis of the ski.
  • the diagonals of these fields extend in the longitudinal direction of the ski, so that the abutting edges inclined to the longitudinal axis of the ski intersect at an acute angle.
  • Such intersections fill up relatively easily with ice or snow, so that the tripping effect is reduced accordingly. Since no kick edge is arranged transversely to the kick direction, the transferable kick is not optimal.
  • AT-PS 348 386 discloses a tread covering with an embossed profile, which, like in CH-PS 189 690, consists of fields which are delimited by a plurality of intersecting sheets of mutually parallel boundary lines. Although there are various distinctive differences to CH-PS 189 690, the disadvantages mentioned are in no way eliminated.
  • DE-AS 22 43 229 discloses a tread formation for cross-country skis, which consists of a pattern of scale-like projections emerging from the tread, at least some of which have a straight edge on their sides, at least one of which is inclined at an angle to the longitudinal axis of the ski , and an edge runs transversely to the longitudinal axis of the ski.
  • the individual projections of a transverse row are separated from one another by narrow, acute-angled depressions that can fill with snow or ice and thus become ineffective.
  • a special process and a relatively complicated tool are required for the production.
  • protrusions protruding from the tread require special measures in ski manufacture.
  • an outsole covering with an embossed push-off aid which consists of a plurality of steps with steeply falling push-off edges in the push-off direction and flat ramps in the sliding direction, the upper side of the steps being more equilateral from a seamless honeycomb arrangement or biaxially symmetrical hexagonal fields is formed.
  • the present invention is based on the object of providing an outsole covering for skis with an embossed push-off aid which ensures optimum transmission of the push-off forces and good lateral guidance, substantially reduces the tendency to block the effective steps by ice and snow and, in addition, a enables simple and economical production of the embossing tool.
  • the design of the outsole covering according to the invention optimally solves the rather complex task which the inventor has set himself.
  • the outsole covering according to the invention is characterized in particular by a considerably enlarged effective scuff edge with the same tread width.
  • the embossing of the tread according to the invention is also much less problematic than the embossing of the tread according to the German utility model mentioned. There is no risk of snow or ice getting stuck in the embossing.
  • the top side of the individual steps is preferably inclined or curved differently in the longitudinal direction in different sections of their length. Thereby an improved sliding behavior of the outsole covering can be achieved.
  • the solution according to claim 4 is particularly suitable for cross-country skis with a width of less than 55 mm in the middle of the ski area.
  • the hexagonal surfaces are formed on the same side.
  • the longitudinal direction of the base or ski extends from left to right in the drawing.
  • the hexagonal sides 1 ′ arranged transversely to the longitudinal direction or the hexagonal sides 1 ′′ offset in the longitudinal direction by the side spacing are kept as steps edges formed.
  • the hexagonal surfaces 2 'or the hexagonal surfaces 2 "offset in the longitudinal direction by half the side distance are designed as gently rising step ramps.
  • at least parts of the hexagonal sides 3 lying obliquely to the repelling direction are also formed steeply falling step edges that can transmit a tangential force.
  • FIG. 2 represents a cross section along the line A-B in FIG. 1.
  • the steeply sloping step edges 1 ' are offset by half the side distance in the longitudinal direction compared to the same edges 1 ".
  • the hexagonal surfaces 2' or 2" drop over their longitudinal extent with a constant inclination angle to the desired step depth, which is advantageously between 0.1 and 1.0 mm. It can clearly be seen that the hexagonal sides lying at an angle to the push-off direction also form 3 push-off edges with a flank part that transmits force in the tangential direction.
  • the result is a two-dimensionally connected network of abutting edges forming all edges of the hexagon, of force-transmitting surfaces in the tangential direction, the height of which is determined by the depth of the step.
  • a large part of all kick edges is perpendicular to the kick direction, so that there is a very effective kick.
  • the sloping edges at an angle to the push-off direction provide very good lateral guidance, since they are arranged symmetrically to the push-off direction. There are no acute-angled intersections that could fill with ice or snow and thus reduce the repelling effect.
  • FIG. 3 shows a cross section along the line AB in FIG. 1 through a further embodiment of the subject matter of the invention.
  • the hexagonal surfaces fall not with a constant incline, but partly lie in the plane of contact of the surface with the track and only then fall off.
  • a striking sliding surface is formed on the top of the step edges, the size of which can be increased to a substantial part of the total hexagonal surface. This makes it possible to vary the sliding behavior over a wide range.
  • Fig. 4 shows a further embodiment of the subject of the invention in plan view.
  • the hexagon fields are not equilateral, but only two-axis symmetrical, so that they have a greater length than width. This makes it possible to choose a particularly flat increase in the hexagonal areas, so that this embodiment offers the possibility of particularly good sliding behavior. However, it would also be possible to choose the width larger than the length.
  • the tread covering according to the invention is particularly well suited for cross-country skis with a width in the ski center area of less than 55 mm.
  • the hexagons are - as shown in FIGS. 1 and 4 - preferably arranged so that in both edge areas of the covering each extending transversely to the direction of repelling edges are arranged.
  • the outsole covering according to the invention also enables very efficient production. While the embossing tools are predominantly produced in one piece by engraving, which is very complex and expensive, the embossing tools can be assembled from individual, similar elements in the covering according to the invention.
  • a flat embossing stamp can, for example, be composed of individual parts with a hexagonal cross section, the size of which corresponds to the hexagonal fields of the covering, and the end face of which is designed in accordance with the slope and curvature of the gently rising step ramp.
  • An embossing roller can simply be assembled from individual, identical disks, the width of which corresponds to the length of the diagonal lying transversely to the repelling direction and the end faces of which are profiled in accordance with the hexagonal sides lying obliquely to the repelling direction.
  • the development of the disks thus has a shape which corresponds to the strongly drawn-out part designated by a in FIG. 1.
  • the lateral surface of the disks must be designed in accordance with the distance between the sides of the hexagon in the longitudinal direction and the inclination and curvature of the gently rising step ramp.
  • the embossing of the tread over a ski length is preferably carried out in such a way that in the middle area, i.e. in the area at Connection to the ski body is below the boot, in particular the ball of the foot, the hexagon fields have a greater longitudinal extent in the direction transverse to the repelling direction or the longitudinal direction of the covering than in the direction parallel to the repelling direction or the longitudinal direction of the covering.
  • the aforementioned goal can be achieved very simply by making the hexagon fields of different lengths in different lengths A, B, C, D with the same width.
  • the number of step edges lying transversely to the repulsion direction is varied per unit area and can easily be adapted to the above-mentioned requirements.
  • Three areas B, C, D, which have increasingly longer fields in the repelling direction and the longitudinal direction of the covering, are added to a middle area A of an outsole covering embossed to ski length with equilateral hexagon fields.
  • the width of the hexagon fields does not change, so that the tread can be produced in a simple manner by the method according to the invention.
  • the central area A of the tread is characterized by equilateral hexagon fields.
  • hexagonal fields in the longitudinal direction of the covering or repelling direction could also be shorter in the central area A of the tread be as transverse to the longitudinal direction of the covering or repulsion direction
  • Fig. 5 the facing width is not chosen so that there are transverse hexagonal sides at the edges.
  • the embodiment with transverse hexagonal sides at the edges is particularly advantageous with regard to the repelling effect.
  • the embodiment according to FIG. 5 is also characterized by a considerably better repelling effect than the treads according to the prior art discussed at the outset.
  • the values for 1, a, b and c given in the table are millimeter values.
  • the area A is only half shown in FIG. 5.
