Definitions

  • the present invention relates to a ski boot comprising a rod articulated at least partially on a bottom of the shell and means for adjusting the resistance of the rod to forward bending, means comprising an elastic support band s 'extending transversely over the upper surface of the bottom of the shell and means making it possible to modify the resistance offered by this elastic band.
  • the upper is articulated on the bottom of the shell and means are provided for modifying the flexural characteristics of the upper relative to the bottom of the shell.
  • Such flexion adjustment means are not only judicious for adapting the ski boot to the different technical levels of the skiers, but also to allow the skiers to adapt the flexural characteristics to the different snow and skiing conditions.
  • ski boots have been fitted with springs or other devices using metal parts.
  • ice tends to form on these metal parts, so that these adjustment devices often become ineffective and even dangerous.
  • US Patent 4,095,356 describes a ski boot in which the opposite and adjacent edges of the upper and the bottom of the shell together define a pocket-shaped cavity in which extends transversely a fixed strip of elastic material ensuring a determined elastic resistance to bending of the rod relative to the bottom of the shell.
  • the elastic characteristics of this bending can be modified by replacing the elastic band with another elastic band of different characteristics.
  • the elastic characteristics of the bending cannot however be modified by the skier who has his shoes on.
  • US Patent 4,445,768 (FR 2,480,575) describes a ski boot according to the preamble of claim 1 in which the elasticity in flexion can be adjusted by the skier who has his boots on.
  • the adjustment means comprise a fixed strip extending transversely over at least part of the instep of the bottom of the shell and a slider which can be moved in the slot formed between the lower edge of the rod and this strip.
  • the band is fixed by its ends either to the bottom of the shell or to the rod and the cursor transmits the movement from the lower edge of the rod to the band, at a point located between the two fixed ends of this band which works in bending. If the cursor is not located in the vertical plane of symmetry of the shoe, which is generally the case, the shoe has an asymmetrical elastic resistance capable of causing an undesirable torsion of the upper.
  • the object of the present invention is to provide a device for adjusting the elastic characteristics of resistance to bending of the rod relative to the bottom of the shell, the actuation of which does not modify the point of action of the bearing force of the rod during of its flexion, in particular retains the dynamic symmetry of the shoe.
  • the ski boot shown in FIG. 1 comprises a shell bottom 10 and a rod 11.
  • the rod consists, in a manner known per se, of a front part 11 a and a rear part 11 b articulated together on the hull bottom 10 by pins 12 and held together by a belt 11c.
  • the rod and the bottom of the shell are made of plastic and relatively rigid.
  • the forward bending of the upper relative to the shell bottom is controlled by a band 13 of variable elasticity in transverse compression, extending transversely to the boot in a groove 14 in the upper face of the shell bottom.
  • the strip 13 is interposed between a support stop 15 integral with the upper and extending from the lower edge of the upper towards the front of the shoe and a rigid surface 16 formed by the side wall of the groove 14 located on the side from the front of the shoe.
  • a longitudinal passage 17 is also provided in the opposite side wall of the groove 14, this passage 17 communicating with the transverse groove 14 for the passage of the support stop 15, so as to allow this support stop 15 to come bear against the side of the strip 13 opposite the rigid support surface 16.
  • the support stop 15 is preferably centered on the shoe, symmetrically relative to the point of articulation 12 of the upper and the passage 17 is therefore also located on the midline of the shell, that is to say approximately in the vertical plane of symmetry of the shoe.
  • the strip 13 works in transverse compression, that is to say in the direction of the support stop 15. It consists of two materials of different stiffness 13a and 13b nested one inside the other.
  • the outer part 13a is made of relatively rigid material, for example polyurethane, while the inner part 13b is made of elastic material, for example rubber, and forms a narrow triangle nested in the rigid material 13a.
  • the strip 13 consequently has a relatively large transverse elasticity, this transverse elasticity gradually decreasing going towards the top of the triangle to be practically zero at the place where only the rigid material 13a is found.
  • the strip 13 is retained in the groove 14 by a cover 19 mounted on the bottom of the hull.
  • the front end of the cover has a bearing surface 20 which engages under a retaining projection 21 formed in the bottom of the shell 10.
  • the opposite edge of the cover 19 is provided with a pair of parallel and slightly curved arms 22, coming in one piece with the cover, extending in the longitudinal direction of the shoe and passing through openings 23 provided in the front face of the upper, on each side of the stop support 15, to maintain the cover 19 on the shell bottom 10, while allowing the rod 11 to oscillate.
  • the lower edges of the cover 19 are provided with pins 24 intended to be fixed by pressure in holes 25 provided in the bottom of the shell.
  • the key cover 19 has an oblong opening 26 which passes through a bent end 27 of the strip 13 allowing the skier to grasp this end 27 to move the strip 13 in the groove 14.
  • the strip 13 can be held in the position chosen by mutual locking means formed along one of the sides of the strip. As shown in FIG. 2, one of the sides of the strip 13 is provided with notches 28 distributed along the strip and intended to receive a tooth 29 formed in the middle of the support stop 15. As a variant, the tooth and the notches could be provided respectively on the support surface 16 and on the other side of the strip 13.
  • the adjacent faces of the support stop 15 and of the strip 13, on each side of the tooth 19, consist of complementary locking surfaces contributing to keeping the strip 13 in position, as can be seen in FIG. 4.
  • variable elasticity in transverse compression of the strip is obtained by openings, in particular circular, of different dimensions and going from one end to the other of the strip. .
  • variable elasticity is obtained by a cutout 18, one stepped side 31 of which gives this cutout a variable width in steps.
  • variable elasticity of the strip is obtained by notches 32 of different dimensions.
  • the strip 13 is made of a more or less elastic material having openings of different dimensions filled with a more rigid material 33.
  • variable elasticity of the strip 13 is obtained by producing the strip by means of several juxtaposed segments such as 34, 35 and 36, of different rigidities, that is to say of different elastic moduli.
  • a protective bellows 37 made of plastic is mounted between the rod 11 and the bottom of the shell 10, above the device for adjusting the bending of the rod, to protect this snow and dirt device.
  • the bellows 37 is provided with two arms 38 by which it is mounted on the bottom of the shell 10 by means of rivets 39.
  • the two ends of the bellows 37 are provided with mushrooms 40 for the pressure fixing of these two ends of the bellows in corresponding holes 41, on one side in the cover 19 and on the other side in the rod 11.
  • the bellows elements 37 have a cutout 42 in their central part for the passage of the support stop 15.
  • the retaining arms 22 of FIG. 6 are replaced by two pallets 43 fixed by rivets 44 at the bottom of the shell 10.
  • the boot according to the invention allows the skier to quickly adjust the bending characteristics of the boot, at any time, by moving the strip 13 in its groove 14. It can thus increase or decrease the resistance of the rod to bending, this without modifying the position of the support zone of the upper on the bottom of the shell, that is to say by keeping the shoe dynamic symmetry.
  • the strip 13 is provided on its underside with a stud cooperating with housings provided in the bottom of the groove 14 for locking the strip 13 in position.
  • the support stop 15 is preferably subjected to bending by the bottom of the shell 10 on which it rests, so as to neutralize the hysteresis effect due to friction.
  • the transverse compression is obtained by a bellows 45 coming in one piece with the strip.
  • This bellows has an effect identical to that of the elastic material 13b.
