Definitions

  • the invention relates to a device comprising a binding element for fixing the cross-country ski boot on a cross-country ski, by means of which the foot can be pivoted about an axis that is oblique to the longitudinal direction of the ski during the running movement.
  • Such a device describes, for example, DE-OS 33 15 641 and is used 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 sequence of movements approximately without torque on the one running in the track or the rear of it ⁇ exercising lifted ski, whereby a slight inclination of the sole of the foot obliquely outwards is not particularly disturbing.
  • a swiveling outward tilting movement moves the toes outwards, the heel somewhat inwards and the knee somewhat 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 sequence of movements especially in the one-sided or double-sided skate step.
  • each axis runs from the intersection on the inside through a point on the outside 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 overall inward pivoting of the turned leg, and thus in the ergonomically more 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, 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 area remains essentially in the same position . The knee is also displaced outwards relative to the heel.
  • the Aclase runs in the area below the imaginary axis of rotation of the basic toe joints of the foot located in the cross-country ski boot.
  • the axis is primarily designed as a physical axle pin.
  • the sole of the cross-country shoe can be designed to be roll-resistant and / or torsion-resistant.
  • the roll-resistant design of the shoe sole leads to relief of the basic toe joints and the associated muscles, and the torsional stiffness 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 embodiment can be realized very easily, in particular, if the sole is designed so that it is 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 edges in the skate step and in the deep lane during the diagonal step.
  • Axis or the axle bolt runs through the cross-country ski, in which at least one bore aligned with the axis is formed.
  • 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 protruding 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 in the binding element can be secured against rotation by 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 also be provided in the swivel space, which effects damping at the angle limiting stop and 5 facilitates the return to the basic position. Furthermore, the elastically compressible insert holds the ski against the shoe when the foot is raised.
  • the axis can be arranged in several 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 when larger distances are also or exclusively run in a diagonal step, as a result of which the usual positioning of the swivel axis is achieved.
  • the center of gravity of the shoe is shifted through the axis lying 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 at an angle. towards the outside 5, with each outer point of the axes 1 closer to the ski tips 8 than their section point 9 lies.
  • the two axes 1 thus converge backwards and downwards and run in the region of the toe basic 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.
  • 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 joint movement than when pivoting about the axis 6 or an axis parallel to it is given by the toe 17.
  • an axis arrangement according to the aforementioned DE-OS 33 15 641, which runs from the inside, top, front to the outside, bottom, back is hardly suitable for the skating step.
  • Axes 1 close with the longitudinal axis of the shoe in the

  • a right shoe 2 is equipped with a thickened sole 12, which in the middle of the width of the cross-country ski has a web 20 which is free on both sides in the toe region.
  • 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 to the toe 17 so that a wedge-shaped space towards the binding element 3 remains free according to FIG Material is used.
  • 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 pivoting lever 23 and are provided with tongues 22 at the rear ends.
  • the sliding guide 25 In the sliding guide 25 there are V-shaped recesses 24 into which the projecting end sections of the axle pin 10 are inserted.
  • the tongues 22 overlap the end sections and fix cylindrical axle bolts 10 on the binding element 3 within the web 20.
  • a shoe 2 which preferably has a roll-resistant and torsion-resistant sole 12 is thus connected to the ski 7 so that it can pivot about the axis 1.
  • a stop 18 adjustable by a screw 27 is provided in the binding element 3, by means of which the lifting angle of the shoe 2 is limited.
  • the web 20 of the sole 12 has the bore 13 coaxial with the axis 1, and the axle pin is formed by two semi-axes 11, which are displaceably mounted in the binding element 3 in the axis 1, and at inserted shoe 2 are partially inserted into the bore 13 from both sides.
  • two blind bores could therefore also be formed his.
  • at least partially longitudinal slides 28 designed as racks 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 can be moved coaxially to the axis 1 in the guide 31 of the binding element 3.
  • the semiaxes 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 Hebel ⁇ mechanism is provided which is actuated by means of a toggle lever 38th 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 transverse arm 34.
  • Each pivot lever 33 is rotatable in bonded bearings 36 and the semi-axis 11 is arranged at its raised rear end, which swivels into the bore 13 from the side.
  • FIG. 13 also indicates the possibility that the sole web 20 has at least one further bore 13 with a different slope, and is provided in the area between the imaginary axis of rotation 6 of the basic toe joints and the toe 17.
  • swivel 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.
