Definitions

  • the invention relates to the sports inventory, more precisely to a ski binding for the running skis.
  • the invention can be used advantageously both for the sport running skis and for the skis in the tourist version.
  • 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 guide surface (and thus the shoe sole plane) forms a considerable angle with the ski track surface, which leads to the creation of strong torsional moments with respect to the shoe sole when the skier pushes off.
  • ski bindings of the company "Adidas” are widely used, 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. For its part, a second lever is arranged on this axis, the free end of which is intended for pressing on the projection of the tip of the sole of the shoe.
  • the skier supports the end of the second lever against the ledge as far as the stop and then presses on the first lever, which in this case is pivoted until the line connecting the two axes comes to lie below a line. which the former axis and the An focus connects. When this position is reached, the shoe is fixed.
  • the disadvantages of this ski binding include considerable binding weight, 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 the skier applies skate.
  • a strong sole twist can be explained not only by the binding construction, but also 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” type ski binding is currently widely used.
  • the binding also represents a plate with side parts that are 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 fixation of the shoe is achieved 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 shoe sole tip parts would match the retaining pins. The skier also presses on the bracket so that he would get into one of the plate grooves.
  • the modifications of this ski binding differ by different types of fasteners:
  • the advantages of the binding include reliable shoe fixation, a lower torque compared to the ski binding from "Adidas" discussed above, which occurs in the plane perpendicular to the longitudinal axis of the ski.
  • the disadvantages include considerable binding weight, poor suitability for manufacturing bindings and locking ler, as well as, 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 Auslegeschrit No. 3240750). One of these parts is intended for direct insertion into the ski body (shoe body). If the lower pin part is arranged in the ski body, the shoe must be adjusted in order to fix it in such a way that the upper parts of the holding pins would enter the bores present in the tip of the sole of the shoe. Various types of locking devices are used to limit the movement of the shoe in the vertical plane.
  • the advantages of this binding include high manufacturing suitability and simple construction, use of retaining pins in combination with various, easy to manufacture 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- GM No. 8425984 which contains holding pins which are attached to the ski and are intended for insertion into associated holes in the tip of the sole of the shoe, as well as a locking device which is designed in the form of a leaf spring which is intended to enclose the tip of the sole of the shoe has the shape of a bow at the top, with one end connected to the ski.
  • the advantages of this binding construction include relatively high manufacturing suitability, low weight, convenient operation. The latter is achieved in that the binding construction according to the invention allows the sole of the shoe to be fixed in automatic operation (without the hands or the ski pole being used by the skier).
  • the object of the present invention is to provide a ski binding, the construction of which would allow the bending moment to be reduced which acts on the binding elements when the skier pushes off.
  • the holding pins which are attached to the ski and are intended for insertion into associated bores in the tip of the sole of the shoe, and a retainer which limits the shoe displacement in the vertical direction, according to the invention at least one with the pin surface contacting surface section of the bore is bent in an arc shape, the curve being substantially coincident with the movement path of the shoe sole section adjoining the retaining pin when the skier is pushed off.
  • the ski binding construction according to the invention permits it to considerably reduce the torque acting on the holding pins and the shoe sole in the zone of the counterbores provided for receiving the holding 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.
  • At least one surface section of the pin contacting the surface of the bore is bent in an arc shape, the bending curve essentially coinciding with the movement path of the shoe sole section adjoining the holding pin when the skier is pushed off.
  • the bore intended for receiving the retaining pin has an extension directed towards the rear part of the shoe, the arcuate surface section of the bore representing a bore surface portion in the extension zone which contacts the retaining pin.
  • This embodiment is somewhat more convenient to manufacture and more convenient to operate because it allows the use of standard 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, and a lock 6.
  • the surface sections of each holding pin 1 and the hole 3 that make contact with one another 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 is pushed 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, but 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 holding pins 1 on the ski 2 are brought into line with the associated holes 3 in the sole 4 of the shoe 5. After inserting the retaining pins 1 into the holes 3, the lock 6 is released.
  • the removable fork 7 is introduced with its two ends, the dimensions of which correspond to the masses of the holes 3, into the holes 3. Then you put the free end of the fork 7 on the lock 6, for example, in such a way that the free end of the fork 7 would encompass the free end of the lock 6.
  • the fork 7 is designed to be easier to fix the shoe 5 to the holding pins 1. A non-releasable connection of the lock 6 and the 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 to the lock 6.
  • FIG. 2 shows an embodiment of the ski binding in which standardized straight pins 1 are used.
  • each hole 3 an extension directed towards the rear of the shoe 5 is carried out.
  • a surface section 8 of the bore 3, which contacts 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 of the shoe 5 which is in contact with the retaining pin 1 when the skier is pushed off.
  • a bow-shaped leaf spring is also used as the arrester, one end of which is rigidly connected to the holding pins 1, but the other end of which is inserted into a groove 9 which is incorporated in the forehead of the tip part of the sole 4 of the shoe 5.
  • 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 bores 3 with the aid 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.
  • the invention can be most advantageously used for sports skis using both the classic and the skate step by the skier.
