Definitions

  • the invention relates to an arrangement of ski binding and ski boot, with holding pins attached to the ski which engage in holes provided in the tip part of the shoe sole, and with a locking device which limits the stroke of the boot in the vertical direction.
  • the demands on the sports inventory have grown and changed considerably. Since the skiers are increasingly using the skate step, the resistance of the ski shoe sole to twisting must be increased because the skier runs on the edge of the ski for a long time. In this case, the ski guiding surface (and thus the sole of the boot) forms a considerable angle with the surface of the ski track, which leads to strong torsional moments in relation to the sole of the boot when the skier is pushed off.
  • ski bindings from the company "Adidas” which represent a plate with side parts which are oriented at an angle to the longitudinal axis of the ski.
  • the plate size and the amount of the angle of inclination of the side parts to the longitudinal axis of the ski are determined by the size and shape of the tip of the sole of the shoe.
  • the binding is intended for use with a ski boot that has a protrusion on the upper surface of the sole part of the shoe sole.
  • the lock on this ski binding is structured as follows. An axis is attached to the plate, on which a lever is attached, which has another axis at its free end. A second lever is arranged on this axis, the free end of which is intended for pressing the projection of the tip part of the sole.
  • the skier supports the end of the second lever up to the stop against the ledge and then presses on the first lever, which is pivoted until the line connecting the two axes comes to lie below a line which the first Axis and the Anchor connects. When this position is reached, the shoe is fixed.
  • the disadvantages of this ski binding include a considerable binding weight, a relatively low manufacturing suitability, which is mainly due to the very complicated manufacture of the locking structure, and the creation of high torques in the horizontal plane. The latter disadvantage is particularly significant when skating.
  • a strong sole twist is not only explained by the binding construction, but is also determined by the narrow tip area of the sole of the "Racing Norm 38" shoe model, the tip of which is narrower than that of the "Racing Norm 50" model.
  • the "Ratafella” ski binding also represents a plate with side parts that lie at an angle to the longitudinal axis of the ski.
  • three pins are attached directly to the plate, which are intended for insertion into the holes in the tip of the shoe sole.
  • the shoe is fixed with the help of a bracket, the free ends of which are received in bushings fastened in the side parts.
  • In the front part of the ski binding there is a plate with grooves on an axis. The shoe is adjusted in such a way that the holes in the toe area of the shoe sole are aligned with the holding pins. Furthermore, the skier presses on the bracket so that he gets into one of the plate grooves.
  • the modifications of this ski binding differ by different types of lock.
  • the advantages of the binding include a reliable shoe fixation, a lower torque compared to the ski binding from the company "Adidas", which is generated in the plane perpendicular to the longitudinal axis of the ski.
  • the disadvantages include a significant binding weight, a low manufacturing suitability of binding and locking, and among other things the need to use the hands (the ski pole) to fix and release the boot.
  • a ski binding which represents holding pins, each of which consists of two parts (see DE-A-3240750). One of these parts is intended for direct insertion into the ski (shoe). If the lower pin part is arranged in the ski, the shoe must be adjusted to fix it in such a way that the upper parts of the holding pins enter the holes in the tip part of the shoe sole.
  • Various types of locking devices are used to limit the movement of the shoes in the vertical plane.
  • the advantages of this binding include a high level of manufacturing suitability and simple construction, as well as the use of retaining pins in combination with various, easily manufactured locks.
  • the disadvantages include relatively low operating properties of the binding when fixing and releasing the shoe because the use of the hands by the athlete is inevitable.
  • a ski binding according to DE-U-8425984 which contains holding pins which are attached to the ski and are intended for insertion into associated bores in the tip part of the shoe sole, as well as a locking device which is designed in the form of a leaf spring which is intended to include the Top part of the shoe sole from above has the shape of a temple, one end of which is connected to the ski.
  • the advantages of this binding construction include the relatively high level of manufacturing suitability, low weight is convenient operation. The latter is achieved in that the binding construction allows the sole of the shoe to be fixed in automatic mode (without the use of the hands or the ski pole).
  • This ski binding construction is characterized by the creation of high tensions in the sole in the area of the holding pins, since all forces are practically absorbed by the holding pins, which can destroy the pins and the sole.
  • the object of the invention is to provide a ski binding, the construction of which makes it possible to reduce the bending moment which acts on the binding elements when the skier repels.
  • this object of the invention is achieved by the features described in patent claim 1.
  • the ski binding according to the invention allows it to considerably reduce the torque acting on the retaining pins and the shoe sole in the zone of the counterbores provided for receiving the retaining pins. This in turn makes it possible to increase the reliability of the ski binding and to extend its useful life. In addition, this binding makes it possible to increase the effectiveness of pushing off the running athlete, because a much lower force is used to bend the sole of the shoe.
  • This embodiment is somewhat more suitable for production and more convenient in operation because it allows the use of standardized straight pins.
  • a damper made of elastic material is arranged in the bore in the extension zone.
  • the ski binding according to the invention contains holding pins 1 (FIG. 1), which are fastened on a ski 2 and are intended for insertion into bores 3 of the sole 4 of a shoe 5, as well as a locking device 6.
  • the contacting surface sections of each holding pin 1 and the bore 3 are curved in an arc shape, the arc of curvature essentially coinciding with the movement path of the section of the sole 4 of the shoe 5 adjoining the holding pin 1 when the skier pushes off.
  • Each arcuate bore 3 is continuous and connects the lower surface of the sole 4 with its front face.
  • the lock 6 of the ski binding is designed in the form of a bow-shaped leaf spring, one end of which is rigidly connected to the ski 2 and the other end of which is provided with a removable fork 7 which is intended for insertion into the holes 3 in the sole 4 of the boot 5.
  • the ski binding works as follows.
  • the lock 6 is pressed away in the direction of the tip of the ski 2 and the retaining pins 1 on the ski 2 are aligned with the associated holes 3 in the sole 4. After inserting the retaining pins 1 into the holes 3, the lock 6 is released.
  • the removable fork 7 with its two ends, the dimensions of which correspond to the dimensions of the holes 3, are inserted into the holes 3.
  • the fork 7 is designed to be easier to fix the shoe 5 to the holding pins 1.
  • a non-detachable connection of the lock 6 and fork 7 could make it difficult to place the holes 3 in the shoe 5 on the arch-shaped retaining pins 1.
  • each bore 3 slides relative to the arcuate retaining pins 1 and the arrester 6.
  • FIG. 2 shows a second embodiment of the ski binding, in which standardized straight pins 1 are used. In each opening 14 an extension directed towards the rear part of the shoe 5 is carried out.
  • a surface section 8 of the opening 14 which comes into contact with the pin 1 and is located in the expansion zone is curved in an arcuate manner, the arc of curvature essentially coinciding with the movement path of the section of the sole 4 which is in contact with the holding pin 1 when the skier pushes off.
  • a bow-shaped leaf spring is also used as the arrester, one end of which is rigidly connected to the holding pins 1 and the other end of which is inserted into a groove 9 which is worked into the forehead of the tip part of the sole 4.
  • a damper 10 made of an elastic material, e.g. made of rubber.
  • a plate 11 is attached between the damper 10 and the holding pin 1, by means of which the contacting of the holding pin 1 with the damper 10 is established.
  • dampers 10 and the plates 11 are held in the openings 14 by means of a plate 12 which is fastened to the sole 4 by means of fastening elements 13.
  • the front part of the sole 4 (Fig. 3) between the lock 6 and the holding pins 1 can be made of an elastic material, e.g. made of rubber. In this case, this part of the sole 4 is deformed when the shoe 5 is lifted.
