Definitions

  • the invention relates to an arrangement of ski binding and ski boot with retaining pins and counter-bores, which are attached to the ski or boot.
  • a ski binding is known from DE-A-32 40 750.
  • Ski bindings of the "Racing Norm 38" and “Racing Norm 50" are currently common, the number each indicating the width of the front boot in mm.
  • the first type of shoe should be preferred in a well-prepared cross-country ski run, because the narrower tip area of the sole of the shoe enables more effective pushing off. Because of the narrower sole tip area, a significantly lower force is used to overcome the sole resistance to bending in the direction of the ski tip.
  • the skating step results in a significant increase in the requirements for sole resistance to twisting.
  • the well-known "Ratafella" ski binding ensures greater rigidity, i.e. the ski is easier to steer.
  • this type of binding does not meet all requirements, e.g. with regard to the skating step, as this will cause the sole to twist.
  • the cross-sectional area of a ski shoe sole made of plastic increases in the direction from the tip of the sole to the heel.
  • the largest cross-sectional area of the shoe sole is in the area of the skier's foot.
  • the holding pins are made in two parts, one part of each holding pin being inserted directly into the ski or shoe body, while the other is to be inserted into the counterbore in the shoe or ski. If the lower pin part is arranged in the ski body, the shoe must be adjusted for fixation in such a way that the upper parts of the pins enter the holes in the tip area of the shoe sole. To limit shoe displacement in the vertical plane different locks are used.
  • the advantage of the known arrangement is that it is easy and simple to manufacture and set up, that it can be quickly assembled and disassembled, and that different types of locking devices can be used.
  • the disadvantage is that the skier has to use his hands to help fix and loosen the shoe.
  • ski binding and boot From DE-Gbm 84 25 984 an arrangement of ski binding and boot is known, the retaining pins attached to the ski are inserted into associated holes in the tip area of the shoe sole.
  • a lock is designed in the form of a leaf spring, which has the shape of a bracket which encompasses the tip region of the shoe sole from above. One end of the leaf spring is connected to the ski.
  • the advantages of the known ski binding include its relatively simple manufacture, low cost, small dimensions, light weight and the possibility of automatically (without using the hands) fixing the boot to the ski.
  • this ski binding can only be used with a ski boot that has a protruding sole tip section or an edge. When pushing off, a horizontal force component is created that acts perpendicular to the longitudinal axis of the ski.
  • the invention has for its object to provide a ski binding in which the forces acting on the holding pin and the sole of the shoe are distributed more evenly.
  • one and the same pair of shoes can be used both for the skating step and for the conventional running step.
  • the ice skating step places higher demands on the load-bearing capacity against sole twisting.
  • the fixing area is expediently moved into the zone of the toes of the skier, that is to say that the fixing area of the shoe and the repelling zone of the skier are combined.
  • the sole width is larger in this zone than in the tip area of the shoe sole. On the one hand, this has advantages when skating because the sole twist is reduced.
  • the expediency of relocating the fixation area is not only due to the step used by the skier, but also due to the weather conditions. In the case of black ice, firn snow and wet snow, the sole twist increases. Under these conditions, it is also expedient to move the fixing area of the boot at a greater distance from the tip area of the sole in order to move the boot closer to the tip of the ski and thereby achieve better ski steering. A similar situation arises, for example, in heavily intersected terrain or on a poorly prepared cross-country trail.
  • the outer surface sections are designed with different dimensions with regard to their length and shape, the frictional forces which determine the reliability of the fixation of the shoe also change accordingly. For example, these forces increase with increasing length of the sections under otherwise identical conditions.
  • a similar situation arises when the shape of their design changes, for example when changing from the cylindrical to the conical shape. The situation is similar with increasing diameter of the pin sections with one and the same diameter of the corresponding bore sections.
  • the friction pairing preferably represents a morse taper (claim 4).
  • ski binding and boot contains retaining pins 1 (FIGS. 1 to 6) which are attached to a ski 2 and counter-bores 3 which are made in the sole 4 of a boot 5. At least a portion of the outer surface of each retaining pin 1 and a surface portion of an associated counterbore 3 touching it form a friction pairing.
  • the friction pairing can be formed by a morse taper or by a self-holding taper.
  • a pair of retaining pins 1 can be assigned several pairs of counter bores 3 which lie along the longitudinal axis of the ski 2 and the boot 5.
  • the arrangement is additionally equipped with an insert 6 (FIG. 1), which is accommodated in each bore 3 and is made of elastic material, for example rubber.
  • the friction pairing is formed by the outer surface of the respective holding pin 1 and the surface of the insert 6 touching it.
  • Fig. 1 operates in the following way.
  • the skier has to press his foot vertically downwards on the sole 4 of the shoe 5 along the axis of the holding pin 1.
  • the pin 1 enters the bore 3, spreading the insert 6 apart and pressing it against the wall of the bore 3.
  • the retaining pin 1 is held in the sole 4 of the shoe 5 by the frictional force, the amount of which increases at the moment of the push-off (the sole bend), which is necessary to ensure reliable fixing of the shoe 5.
  • the shoe 5 is fixed by elastic contact forces on the surfaces of the insert 6 and the retaining pin 1.
  • An advantage of this construction is, in addition to its simple structure and its suitability for production, as well as its low weight in the event of a lock, in practically completely avoiding play and consequently in little connection wear and good steering of the ski 2.
  • a reinforcement bushing 7 (Fig. 1-6) can be arranged, which consists for example of metal.
  • the attachment can additionally be equipped with a corresponding device.
  • a threaded connection in the form of a hollow screw 8 (FIG. 2) can be used, which is located in a threaded section 9 of the reinforcement bushing 7, which in turn is in the projecting tip portion of the Sole 4 of the shoe 5 is arranged.
  • the insert 6 is received in the cavity of the screw 8.
  • the arrangement shown in Fig. 2 operates as follows. Before the shoe S is fixed, the insert 6 is expediently relieved, as a result of which the most favorable conditions for inserting the holding pin 1 into the bore 3 in the sole 4 are created. Then one increases, by screwing the screw 8 into the socket 7, the load acting on the insert 6. As the load increases, the adhesion of the elastic material of the insert 6 and thus of the sole 4 of the shoe 5 to the holding pin 1 and accordingly also to the ski 2 increases. So there is the possibility to improve the functional conditions of the retaining pin 1 and To increase reliability and service life of the same. If the insert 6 is worn, it can be replaced.
  • the reinforcement bushing 7 is mounted in the sole 4 in the zone of the toes of a skier, and the threaded section 9 for inserting the screw 8 is located in the lower part of the bushing 7.
  • a screwdriver slot 10 is made therein for turning the screw 8 .
  • the required degree of compression of the insert 6 is set by turning the screw 8, after which the retaining pin 1 is inserted into the bore 3 in the sole 4 of the boot 5.
  • the force that secures the shoe 5 on the ski 2 against displacement in the vertical plane is determined by the pressure acting on the insert 6.
  • corrugations or annular grooves 11 can be carried out on the outer surface of the holding pin 1.
  • FIG. 5 shows an embodiment of the arrangement in which a pair of retaining pins 1 are attached to the ski 2, while a pair of reinforcement bushings 7, which are made in one piece with a plate 12, are arranged in the sole 4 of the boot 5. Between the bushings 7 there is a hole in the sole 4 for inserting an adjusting screw 13 into the same and screwing this screw into a threaded hole 14 provided in the plate 12.
  • the plate 12 is located in a cavity 15 of the sole 4 and is when the screw is turned 13 bendable in this cavity 15.
  • the angle between the axes of the bores 3 in the reinforcement bushings 7 changes.
  • the axes of the retaining pins 1 and the axes of the associated bores 3 are not in alignment.
  • the arrangement shown in Fig. 5 operates as follows. Before starting work, the required angle between the axes of the bores 3 is set by turning the screw 13, which ensures a predetermined frictional force between the surfaces of the retaining pins 1 and the bores 3 coming into contact.
  • FIG. 6 shows a further embodiment of the arrangement according to the invention.
  • One or more pairs of retaining pins 1 are attached to the ski 2.
  • One or more pairs of reinforcement bushings 7 are arranged in the sole 4 of the shoe 5. Between the bushings 7 there is a cylinder 16, in the interior of which an elastic insert 17 is accommodated. Each bushing 7 is equipped with a rod 18, the free end of which is inserted into the cylinder 16 and is supported against the insert 17 via a flange 19.
  • the distance between the axes of the holes is slightly larger than the distance between the axes the retaining pins 1.
  • the upper end of each retaining pin 1 must lie in the zone of an associated hole 3.
  • the ski 2 To release the shoe 5 from the ski 2 (FIGS. 1-6), the ski 2 must be fixed and a force applied to the shoe 5, which is directed upwards along the longitudinal axis of the holding pins 1.
  • the retaining pins 1 and the counterbores 3 can each be attached both to the ski 2 and to the sole 4 and vice versa. As the practical use of the ski binding according to the invention has shown, these connections work very reliably.
  • the adhesive force between the outer surface of a holding pin 1 and the surface of a bushing 7 arranged in a bore 3 is determined by the cone ratio and the type of material of the upper part of the holding pin 1 and the bushing 7 as well as by the structure of the contact surfaces (processing quality, specially provided knurling, Roughening, etc.).
