Definitions

  • the invention relates to a ski boot with a damping device and a rigid shell according to the preamble of claim 1.
  • an elastic element is provided between the underside of a rigid shell and a sole, made of essentially solid or bending-resistant material, which absorbs impacts and shocks that act on the skier's leg, especially in the heel area.
  • a sole made of essentially solid or bending-resistant material, which absorbs impacts and shocks that act on the skier's leg, especially in the heel area.
  • This load can lead to undesired wear and tear, which does not optimally guarantee the firmness of the ski boot required to trigger a safety ski binding.
  • CH-PS 587 032 shows further known designs; however, the elastic devices or inserts there have the purpose of facilitating the rolling movement when walking.
  • DE-OS 37 42 918 also shows elastic elements in the heel area in some of its versions, the elastic elements being located directly in or on the heel.
  • the heel is formed in one piece with the sole or attached to the underside of the shell by a releasable connection. Since there is a rigid rib between the elastic elements, which transfers the forces directly from the heel to the shell and thus to the skier's foot, the damping effect to be applied in the vertical plane is also lost here. Only forces that occur when the ski boot is in a certain position, for example when edging, can therefore be damped.
  • the object of the present invention is to remedy this and to ensure effective damping without restricting the acting direction of force while maintaining the necessary strength.
  • the object is achieved by the characterizing features of claim 1.
  • the measures according to the invention result in guide surfaces for the elastic element which do not impair the effectiveness of the damping device, so that it can absorb these impacts from all directions. Furthermore, these guide surfaces ensure the strength required to release a bond.
  • the measures according to claim 2 result in divided profiles with an advantageous design, the same strength being achieved with less material with respect to the main direction of loading.
  • the operation of the damping device is improved in that the contact surface between the elastic element and the detachable heel increases.
  • this configuration leads to better anchoring of the two parts to one another.
  • a uniform pressure distribution between the elastic element and the heel is achieved by the embodiment according to claim 6.
  • Claim 7 ensures an unimpeded relative movement between the shell and heel by the heads of the fastening screws.
  • FIG. 1 shows a ski boot according to the invention in side view
  • Figure 2 shows a diagram of the elastic element and the heel according to the first
  • 3 is a longitudinal section through a detail according to FIG. 1 according to the second exemplary embodiment
  • FIGS. 4 and 5 are cross sections along the line IV-IV and V-V in FIG. 3.
  • ski boot 1 shows a ski boot 1 in its entirety, with an elastic element 3 and a detachable heel 4 on its rigid shell 2.
  • Figure 2 shows the elastic element 3 and the paragraph 4 together in an exploded view, each in an elevation.
  • the elastic element 3 has a plate 3a and an upwardly directed and self-contained profile 3b.
  • the plate 3a has the shape of a trapezoid on its side facing the tip of the ski shoe, the area of the plate 3a facing away from the tip of the ski shoe is designed as a circular arc.
  • the upward profile 3b has outer surfaces 3c which run inside and essentially parallel to the outer contour of the plate 3a.
  • the profile 3b delimits a surface 3d with four through bores 5 which serve for the passage of fastening screws, not shown in this figure.
  • the surface 3d and an upper side section 3e of the plate 3a running outside the profile 3b form a plane on which the elastic element 3 is supported horizontally on a lower side 2a of the shell 2 of the ski boot 1 (not shown in this figure) (see FIG. 1). .
  • the elastic element 3 On its underside 3f, the elastic element 3 has a recess 3g, which is designed as a groove and runs under or in the profile 3b (see FIGS. 3-5).
  • FIG. 2 also shows the detachable shoulder 4 made of solid or bending-resistant material, said shoulder 4 having a plate 4a whose outer contour corresponds in plan view to that of plate 3a of the elastic element.
  • the plate 4a has an upwardly projecting support part 4b, the side surfaces 4c of which are essentially the same inside and run parallel to the outer contour of the plate 4a, like the profile 3b of the elastic element 3.
  • a surface 4d delimited by the support part 4b has four stepped bores 5a, which are used to hold fastening screws (not shown in this figure) (see FIG. 6 in FIG. 5 ) serve.
  • FIGS. 2a to 5 show above all a basic embodiment of the invention. The interaction of the individual parts is now to be explained on the basis of a second embodiment according to FIGS. 2a to 5, which is preferred for practical use, from which figures the structure of the shell 2 of the ski boot 1 also emerges.
  • FIG. 2a shows an elastic element 13 and a shoulder 14.
  • the shape and structure of the two parts essentially correspond to the first embodiment according to FIG. 2 with the difference that the plate 13a of the elastic element 13 has two upwardly projecting profiles 13b, 13h with outer surfaces 13c, 13i and the plate 14a of the shoulder 14 has two upstanding support parts 14b, 14h with outer surfaces 14c, 14i.
  • the profiles 13b, 13h or the support parts 14b, 14h each delimit a surface 13d or 14d with through or stepped bores 15 or 15a.
  • an intermediate plate 13j with a recess in which an intermediate plate 14j, which extends between the support parts 14b, 14h and the plate 14a, engages properly.
  • Each of the intermediate plates 13j, 14j has an outer surface 13r, 14r, whose outer contour runs inside and essentially parallel to the outer contour of the respective plate 13a or 14a.
  • the one profile 13b or the one support part 14b has a substantially U-shaped configuration in plan view, the open side of the profile 13b or the support part 14b pointing towards the ski tip.
  • the plate 13a of the elastic element 13 has a second profile 13h, formed as a lying prism, and the plate 14a of the shoulder 14 has a similarly designed and arranged support part 14h.
  • the longitudinal axis of the second profile 13h or support part 14h is normal to the longitudinal axis of the ski boot.
  • the elastic element 13 has on its underside 13f two recesses 13g, 13k, these being designed as grooves and running under or in the profiles 13b or 13h (see FIGS. 3-5).
  • a top section 14m of the plate 14a which extends outside the support part 14b, has depressions 14n, which are also formed as lying segments of circular cylinders.
  • Figures 3 to 5 show the paragraph 14 and the elastic element 13 positively connected to each other and mounted on the underside 2a of the shell 2.
  • the positive connection is created by the downwardly projecting projections 13n elastic element 13, which engage in the recesses 14n of the shoulder 14, and by the engagement of the support parts 14b, 14h of the shoulder 14 in the recesses 13g, 13k on the underside 13f of the elastic element 13.
  • the underside 2a of the shell 2 has a recess 2b with four downwardly projecting pins 7, each of which is provided with a fastening screw 16 for receiving it.
  • the profiles 12b, 12n of the elastic element 13 and the support parts 14b, 14r also protrude into the recess 2b of the shell 2. of paragraph 14.
  • the elastic element 12 is supported on the underside 2a of the shell 2 and on the end faces 7a of the pins 7.
  • the outer surfaces 13c, 13i of the profiles 13b, 13h bear against side walls 2c of the recess 2b.
  • the recess 2b corresponds in its front area to the course of the side flaps 13r of the intermediate plate 13j (not shown).
  • the stepped bores 15a are formed on the underside of the shoulder 14 in such a way that the fastening screws 16 are countersunk with their heads 16a to an extent which, with any compression of the elastic element 13, causes the heads 16a to protrude from the underside of paragraph 14 avoided with certainty.
  • the ski boot 1 is in the rest position. If a shock or impact acts on the ski boot 1 from below, the elastic element 3, 13 becomes between the underside 2 a of the shell 2 or the End faces 7a of the pin 7 and the paragraph 4.14 compresses and causes damping.
  • the elastic element 3, 13 is compressed between the side walls 2c of the recess 2b and the outer surfaces 14c, 14i of the support parts 14b, 14h of the shoulder 14.
  • the heel plate can, for example, be provided with a longitudinal rib (s.l4p in dash-dot lines in FIG. 2a) in order to increase the flexural strength of the shoulder.
  • the height distance between the longitudinal rib and the underside of the shell is greater than the extent of the intended compression.
  • the plate of the elastic element has a corresponding passage opening for the longitudinal rib, which does not influence the damping (see dash-dot line in FIG. 2a).
  • other rib constructions with corresponding passage openings in the plate of the elastic element are also essential to the invention, for example in shape a cross or a double cross, a lying X-es and the like.
  • FIG. 2b shows a variant in which the rib 4p of the surface 4d of the shoulder 4 is also assigned a rib 3p of the surface 3d of the elastic element 3.
  • the structure and mode of operation of this variant correspond to those already described.
  • the type of attachment of the heel to the underside of the ski boot is not restricted to the use of fastening screws, since riveting, gluing or welding is also conceivable.

Abstract

La présente invention se rapporte à une chaussure de ski (1) munie d'un dispositif d'amortissement et d'une coque rigide (2). Dans le cas d'une chaussure de ski connue de ce genre est prévu entre le dessous de la coque de chaussure rigide et sa semelle un élément élastique absorbant les chocs verticaux. En cas de chocs horizontaux, il peut se produire des efforts de cisaillement nuisibles entraînant une usure prématurée et/ou n'assurant plus la rigidité requise pour le dégagement de la chaussure de ski hors d'une fixation de sécurité. Selon l'invention, l'élément élastique (3) présente au moins un profil (3b) orienté de sa plaque (3a) vers le haut et s'adaptant dans un évidement (3g) du dessous de la coque. Dans le profil s'insert un élément de support également dirigé vers le haut et faisant partie d'un talon amovible, le bord supérieur de cet élément de support dépassant le dessus du plan dans lequel s'appuie horizontalement l'élément élastique sur le dessous de la coque.
