Definitions

  • the invention relates to a device comprising a binding element and a cross-country shoe for fixing the cross-country ski boot on a cross-country ski, by means of which the foot can be pivoted about an axis which is oblique to the longitudinal direction of the ski during the running movement.
  • Such a device describes, for example, DE-OS 3 315 641 and serves to improve the directional stability of the cross-country ski in conventional cross-country skiing in the diagonal step.
  • the two swivel axes of the pair of ski converge towards the front, i.e. their imaginary intersection is closest to the ski tips.
  • the inclined pivot axis means that the foot can follow the natural movement sequence almost without torque on the one running in the lane or lifted out of it Exercise skiing, with a slight incline of the sole of the foot not particularly disturbing at an angle to the outside.
  • a swiveling tilting movement moves the toes outwards, the heel a little inwards and the knee a little outwards.
  • Such a displacement of the body part is, however, contrary to the anatomical movement sequence in a skating step, as must also be used according to the conventional cross-country skiing technique.
  • an outward tilting movement of the foot is extremely unfavorable.
  • the invention has now set itself the task of creating a device of the type mentioned, which accommodates the movement sequence especially in the one-sided or double-sided skate step.
  • each axis runs from the intersection of the two axes between the two cross-country skis on the inside of the cross-country ski through a point on the outside of the cross-country ski that is closer to the ski tip than the intersection of the axes.
  • the main advantages of this arrangement for the skate step lie in the total inward pivoting of the twisted leg, and thus in the more ergonomically favorable position of the force introduction point, in an increase in the push-off pressure and / or in an extension of the push-off phase, whereby the stress and the risk of injury to the foot , Leg and hip joints are reduced at the same time.
  • this pivot axis arrangement causes the heel to shift inwards, while the knee region remains essentially in the same position. The knee is also displaced outwards relative to the heel.
  • the axis runs in the area below the basic toe joints of the foot located in the cross-country ski boot.
  • the axis is primarily designed as an axle bolt.
  • the sole of the cross-country shoe can be designed to be roll-resistant and / or torsion-resistant.
  • the roll-resistant design of the sole of the shoe relieves the strain on the basic toe joints and the associated muscles, and the torsional rigidity results in a much better transmission of the lateral forces.
  • Cross-country skiing can be improved and the previous assembly of guide ribs and heel plates on the ski can be omitted.
  • the axle or the axle bolt runs through the sole of the cross-country ski boot, in which at least one bore is aligned with the axle.
  • This version can be realized very easily, in particular, if the sole is designed to be resistant to rolling, since it can then be provided in the necessary or arbitrary thickness.
  • a thick shoe sole is an advantage anyway, since friction losses can be reduced both when using the edge in the skate step and in the deep lane during the diagonal step.
  • a second equivalent embodiment provides that the axle or the axle bolt runs through the cross-country ski, in which at least one bore is aligned with the axle.
  • axle pin protrudes from the bore on both sides and engages in the binding element.
  • a binding element suitable for fixing the axle bolt can be constructed very simply. If, for example, U- or V-shaped receptacles are formed in the binding element for the projecting ends of the axle bolt, its fixing by spring-loaded locking bolts which close the U-shaped receptacles after insertion of the axle bolt is conceivable.
  • the axis bolt can be secured against rotation in the binding element in that the projecting ends are angular.
  • the axle bolt consists of two semi-axles which are arranged in the binding element and can be inserted into the bore.
  • the mere formation of a hole or two blind holes is required in the sole or in the ski, while the semiaxes are arranged or articulated, for example, in lateral guides of the binding element, and can be inserted or pivoted into the holes.
  • a preferably adjustable stop can be provided on the binding element.
  • an elastically compressible insert usually in the form of a wedge, can be provided in the pivoting space, which is a damper effect at the angle limit stop and the return to the basic position is facilitated. Furthermore, the elastically compressible insert holds the ski against the shoe when the foot is raised.
  • the axis can be arranged in different positions in the area between the tip of the shoe and the imaginary axis of rotation of the basic toe joints.
  • Such an embodiment is particularly advantageous if larger distances are also or only run in diagonal steps, as a result of which the usual positioning of the pivot axis is achieved.
  • the center of gravity of the shoe is shifted through the axis under the basic toe joints, so that the shovel of the ski is lifted more easily.
  • FIG. 1 shows a top view of a pair of cross-country skis 7, 3 cross-country shoes 2 being pivotally arranged about axes 1 in schematically arranged binding elements 3.
  • the imaginary intersection 9 of the two axes 1 lies between the inner sides 4 of the shoes 2, and the two axes 1 rise obliquely towards the outer side 5, with each outer point of the axes 1 being closer to the ski tips 8 than theirs Intersection 9 lies.
  • the two axes 1 thus converge backwards and downwards and run in the region of the basic toe joints, the imaginary axes of rotation of which are designated by 6.
  • FIG. 3 shows a schematic top view of the pair of skis in the skating step. Especially from this illustration it can be clearly seen that the heel of the repelling right foot can be lifted off the ski due to the pivoting about the inclined axis 1 and can be more natural and closer to a natural articulation than when pivoting about the axis 6 or an axis parallel to this is given by the toe 17. It can also be seen that an axis arrangement according to DE-OS 3 315 641 mentioned at the outset, which runs from the inside, down, in front, out, up, in the back is hardly suitable for the skating step.
  • the axes 1 preferably form an angle of 70 ° to 86 ° with the longitudinal axis of the shoe in the projection onto the surface of the ski and an angle of 5 ° to 20 ° with the surface of the shoe.
  • a right shoe 2 is equipped with a thickened sole 12 which has a bridge 20 in the toe region which is free on both sides in the middle of the width of the cross-country ski.
  • the web 20 is provided with a bore 13 through which the axis 1 runs, and in which an axle bolt 10 is inserted, which has triangular round sections projecting on both sides.
  • the web 20 is inclined towards the toe 17 so that a wedge-shaped space towards the binding element 3 remains free according to FIG is.
  • the shoe 2 can thus be pivoted about a slight resistance about the axis 1.
  • the binding element 3 has two parallel longitudinal slides 21 which can be actuated via a pivot lever 23 and are provided with tongues 22 at the rear ends.
  • the sliding guide 25 there are V-shaped recesses 24 into which the projecting end sections of the axle bolt 10 are inserted.
  • the tongues 22 overlap the end sections and fix 20 cylindrical axle bolts 10 on the binding element 3 within the web 20.
  • the shoe 2, which preferably has a roll and torsion-resistant sole 12, is thus connected to the ski 7 so that it can pivot about the axis 1.
  • a Screw 27 adjustable stop 18 is provided, through which the lifting angle of the shoe 2 is limited.
  • the web 20 of the sole 12 has the bore 13 coaxial with the axle 1, and the axle bolt is formed by two semi-axles 11, which are displaceably mounted in the axle 1 in the binding element 3 and when inserted Shoe 2 are partially inserted into the bore 13 from both sides.
  • two blind bores could therefore also be formed.
  • 9 and 10 at least partially designed as toothed racks 28 are guided on the binding element 3, into which toothed actuating wheels 29 engage at the front end.
  • each longitudinal slide 28 has an inclined driving web 30 which engages in an opposite recess in the semiaxis 11, which are displaceable coaxially to the axis 1 in the guide 31 of the binding element 3. When the longitudinal slide 28 is actuated, the semi-axes 11 are therefore necessarily pushed into or out of the bore 13.
  • a shoe 2 is again used, the sole web 20 of which has a bore 13 into which two semi-axes 11 can be pivoted.
  • a lever mechanism is provided in the binding element 3, which can be actuated by means of a toggle lever 38.
  • This is pivotable about an axis 39 and has two rollers 37, each of which presses on a leg 35 of a pivot lever 33 which is connected to the leg 35 via a cross arm 34.
  • Each pivot lever 33 is rotatable in bonded bearings 36 and the semi-axis 11 is arranged at its upstanding rear end, which swivels into the bore 13 from the side.
  • the sole web 20 has at least one further bore 13 with a different slope, and is given in the area between the imaginary axis of rotation 6 of the basic toe joints and the toe 17.
  • pivot levers 33 of different lengths are preferably also provided, which are interchangeable, so that a larger number of positions and positions of the axis 1 can be reached.
  • FIGS. 14 and 15 show a schematic illustration of an embodiment in which the axes 1 run through the ski 7.
  • the binding element 3, which does not show a shoe 2 in an embodiment, has downwardly projecting tabs 40 or the like, which are arranged pivotably on the side of the ski 7.
  • the ski is penetrated by protruding axle bolts 10 or two semi-axles arranged on the tabs 40 are also provided here, which can be inserted into the bore 13 of the ski. Different positions can also be achieved here, for example, if several bores are formed in the ski 7.
  • the conventional flexible design of the shoe sole 12 is no longer necessary, but it can be rigid at least from the swivel range to the heel 16, which means that the sole thickness can also be arbitrary.
  • a roll-resistant and torsion-resistant sole 12 also improves the hold in the binding element, which is especially necessary in the skating step, so that heel guide parts can be dispensed with.
