Definitions

  • the invention relates to a cross-country ski, the bending stiffness should be adjustable similar to a known alpine ski.
  • the applicant is aware of an alpine ski that is provided with a tensioning device with a front and rear tensioning strap, each of which engages the lower flange of the ski body.
  • the tensioning straps extend almost over the entire length of the ski, in order in particular to be able to influence the vibration behavior of the front part of the ski and the rear part of the ski.
  • a spring assembly was also integrated in each of the straps.
  • the inventors have now found that the known solution is completely unsuitable for cross-country skis.
  • the properties of a cross-country ski with regard to its classification as a beginner or advanced ski or the body weight of the runner depend to a very large extent on the stiffness distribution in the so-called secondary tension zone.
  • the secondary tension zone is understood to mean that middle ski area which, when loaded with a predetermined weight corresponding to the average body weight for which the ski is designed, does not touch a flat surface.
  • the secondary tension zone essentially corresponds to the impression area in contrast to the front and rear sliding areas of the ski.
  • the stiffness in the secondary tension zone is known to be primarily influenced by the dimensions and material of the straps, by the course of the wedge curve and by the adjustment of the pretension height when the ski is glued.
  • the present invention has for its object to provide a cross-country ski that can be adapted to different runner weights and running techniques in a simple manner.
  • the free ends of the tensioning strap or straps are preferably attached to the front and rear end sections of the secondary tension zone of the ski by gluing to the underside of the ski body or ski body wedge.
  • the tensioning straps are freely movable in the longitudinal direction of the ski, that is to say they are stretchable, wherein, of course, stretching straps that are as free of stretching as possible are to be used.
  • the tensioning straps are preferably made of materials with high tensile strength, high elastic modulus train and low density, such as fiberglass laminate, Kevlar, Carb onmaschine, stainless steel, or the like.
  • the basic construction of the ski is advantageously always chosen so that it has its lowest necessary bending stiffness in the normal state. Only when the tensioning device is actuated can the bending stiffness be increased to the desired extent. In case of failure or In this way, breakage of the tensioning straps or tensioning device means that the ski remains fully operational, since it then has its original design-related stiffness distribution.
  • the construction of the tensioning device can be designed such that the front and rear part of the tensioning strap or straps with respect to the point of application of the tensioning means on the tensioning strap or ties is symmetrical or asymmetrical, i.e. with the same or different tensile force.
  • the solution can be designed according to claim 3 or claim 15.
  • FIG. 1 shows schematically a cross-country ski 10 with a ski binding 16 arranged on the top surface and a tensioning device 20 to be described in more detail for adjusting the hardness of the ski.
  • the voltage distribution in the so-called secondary voltage zone is very important for a cross-country ski, since this zone is the impression area which e.g. Climbing aids such as scales or skins are assigned.
  • the secondary voltage zone is labeled "S" in FIG. With regard to the definition of the secondary voltage zone, reference is made to the above statements.
  • the balance point of the ski 10 is identified by the reference number 18.
  • the ski binding 16 is also mounted in this area, as is generally customary.
  • the tensioning device 20 comprises two, in the longitudinal direction of the ski 10 extending in the longitudinal direction of the ski, parallel and continuous tensioning straps 22, the free ends of which are fastened, preferably glued, to the front and rear section of the secondary tension zone on the underside of the ski body. Furthermore, the tensioning device 20 comprises a tensioning bracket 30 (cf. also FIG. 2), with a support surface for the two tensioning straps 22 which is curved in the longitudinal direction of the ski, a tensioning bolt 32 mounted upright in the ski body 12, the lower end of which is rotatably mounted in the tensioning bracket 30 and the upper end thereof With an external thread 41 is provided which interacts with an internal thread 42 of a tensioning button 34 which is supported on the ski top surface via an intermediate disk 36.
  • the tensioning straps 22, as can be seen in FIG. 2, are guided in plastic tubes 44 on the underside of the ski body or between the ski body 12 and the tread 14 in a freely movable manner in the longitudinal direction of the ski.
  • the plastic hoses 44 ensure an unimpeded movement of the tensioning straps 22 and a transmission of the tensioning force to the fastening points of the tensioning straps 22 on the underside of the ski body or on the lower flange of the same.
  • the tubes 44 which are preferably made of low-friction polyethylene, are advantageously embedded in corresponding longitudinal grooves on the underside of the ski body 12 or on the side of the tread 14 facing the ski body 12.
  • the clamping bolt 32 screws into the clamping button 34, whereby the clamping block 30 is subjected to an upward force and the clamping bands 22 are subjected to a clamping force, bolts 26 and 28 extending transversely to the longitudinal direction of the ski and approximately parallel to the top surface of the ski, as an abutment for the clamping bands 22 serve.
  • the bolts 26, 28 are preferably mounted in a plastic or light metal housing 60 inserted in the recess 58 of the ski body 12, which is provided on the underside or on the side facing the tread 14 with a flat cover 62, so that an uninterrupted lower belt surface is guaranteed, on which the tread 14 rests or is glued.
  • the bearing housing is inserted in a lower recess 58 of the ski body 12.
  • the tensioning device acc. Figure 2 allows a continuous adjustment of the bending stiffness or hardness of the ski.
  • tensile force compensation takes place between the front and rear part of the tensioning straps 22, so that the hardness is adjusted symmetrically with respect to the point of application of the tensioning means or tensioning bracket 30.
  • the tensioning button 34 also has an integrally formed pointer 38 which follows the movement of the tensioning button 34 and indicates the position of the tensioning button 34 from the tension-free zero position on a marking 40 on the ski top surface.
  • the tensioning straps 22 can be subjected to deformation of the lower flange in the area of the secondary tension zone "S" e.g. counteract progressively.
  • a compression spring not shown in FIG. 2, preferably a helical compression spring, is also provided, which tries to force the tensioning bolt into the ski body. That is, clamping bolt 32 and clamping block 30 can always be moved upwards against the pressure of an elastic element by corresponding rotation of the clamping knob 34. To avoid any rattling noises that may occur, the recess 58 can be filled with an elastic foam.
  • FIGS. 3 and 4 A further embodiment of the cross-country skiing gravel designed according to the invention is shown schematically in FIGS. 3 and 4, only the part having the tensioning device being shown. Parts which have already been described with reference to FIGS. 1 and 2 are provided with the same reference numbers in FIGS. 3 and 4. With regard to the function and meaning of these parts, reference is therefore also made to the corresponding description of FIGS. 1 and 2.
  • the tensioning device 20 integrated approximately in the region of the balance point of the ski in the ski body 12 comprises two tensioning rollers 46, 48, which are each rotatably mounted about an axis extending transversely to the longitudinal direction of the ski and parallel to the top surface of the ski.
  • the tensioning means 24 are thus in the embodiment according to FIGS. 3 and 4 horizontal tensioning rollers, while in the embodiment according to FIGS. 1 and 2 an upright tensioning bolt 32 and tensioning bracket 30 serve as support for the tensioning straps 1 of FIG. 22.
  • the tensioning rollers 46, 48 are rotatably mounted in the housing 60, the pivot bearings being identified by the reference numbers 54, 56 (FIG. 4).
  • the front tensioning roller 46 is assigned a front tensioning strap 22 'and the rear tensioning roller 48 is assigned a rear tensioning strap 22 ".
  • the two tensioning rollers 46, 48 can be actuated independently of one another, so that the tensioning straps 22' and 22 "can be wound onto the tensioning rollers 46 or 48 to different degrees and thus the Vdr tension in the front secondary tension zone and rear secondary tension zone can be changed individually.
  • the two tensioning rollers 46, 48 can also be coupled to one another in a geared manner, so that only one tensioning roller needs to be actuated in order to rotate the other tensioning roller in the same way. This way it is symmetrical Change in the preload in the secondary voltage zone ensured.
  • the two tensioning rollers 46 and 48 are accessible from the outside on a side cheek of the ski body 12, in each case via square holes 50, 52, into which corresponding actuating tools can be inserted.
  • square holes 50, 52 instead of square holes, hexagonal holes can also be provided for corresponding socket wrenches.
  • the free ends of the tensioning straps 22 ′ and 22 ′′ which can be tensioned independently of one another, are of course again fastened in the region of the end sections of the secondary tension zone to the lower flange of the ski body, preferably glued on.
  • the embodiment according to FIGS. 3 and 4 has the advantage that the tensioning device 20 can be anchored in the ski body 12 in a completely weight-neutral manner, since no actuating means protrude from the ski top surface, which require an arrangement in front of the ski binding 16.
  • each tensioning roller 46 and 48 are rotatably supported in a manner known per se. Furthermore, each tensioning roller is assigned an overload safety device, which takes effect before the tension limit of the tensioning straps 22 'or 22 "is reached.
  • the rotational position of the tensioning rollers 46, 48 can be read from corresponding markings 64, 66 on the side cheek of the ski, on which the two tensioning rollers 46, 48 are guided outwards. According to FIG. 4, these markings can be angle scales, the rotational position of the tensioning rollers 46, 48 being indicated by pointers 68, 70.
  • the two tensioning rollers 46, 48 are each provided with overload safeguards in order to ensure that the Prevent straps 22 ', 22 ".
  • the tensioning device 20 is of course also provided with an overload safety device, this being e.g. is formed by a predetermined breaking point outside the ski body 12.
  • an overload safety device e.g. is formed by a predetermined breaking point outside the ski body 12.
  • the clamping bolt 32 consist of a very resistant stainless steel
  • the clamping button 34 is made of a relatively soft plastic, so that when the clamping button 34 is overturned, only its internal thread 42 breaks out or is destroyed. This damage can be easily remedied by renewing the tension button 34.
  • Another possibility is to secure an internally threaded sleeve in the clamping knob 34 by means of a radially acting ball catch of a known type. After exceeding a predetermined torque, the ball catch then yields, so that the tensioning knob 34 can be turned further without the excessive torque being transmitted to the female threaded sleeve cooperating with the tensioning bolt 32.
  • the last-mentioned overload protection is also suitable for the embodiment according to FIGS. 3 and 4 in order to prevent the two tensioning rollers 46 and 48 from being overtightened and thus to prevent the tensioning straps 22 ′, 22 ′′ from breaking undesirably.
  • the threads 41, 42 according to FIG. 2 have a relatively low inclination. In this way, self-locking of the tensioning device 20 is ensured. An additional locking is no longer necessary.
