Definitions

  • a sole for ski boots is described having a substantially rectangular base member narrower than the width of the ski boot upper and attached to the lower portion of the ski boot upper.
  • the substantially rectangular base member is defined by two parallel relatively shorter edges forming the front and rear edges of the base member and relatively longer edges forming the lateral edges of the base member.
  • the width of the front and rear edges are equal to or less than the width of a narrower standard width ski.
  • the width of the front edge is less than the width of the narrower standard width ski and the width of the rear edge is equal to the width of the narrower standard width ski.
  • the inner lateral edge of the base member extends from the front edge to the rear edge in a straight line.
  • the outer lateral edge forms a line extending from the front edge rearwardly and outwardly of the boot and a second line extending from the rear edge forwardly and outwardly of the boot, said lines converging at a point substantially in the region of the ball of the foot.
  • the Width of the base member at the point where these lines converge is equal to or greater than the width of a wider standard width ski.
  • ski boots which have a narrower base than the shoe and have straight edges. These straight edges improve the guidance of the ski and cause a minimum of contact with the snow, thus avoiding the braking action of the sole in the snow.
  • the edges which limit the base are parallel to each other, so that the base has an elongated rectangular shape.
  • the width of the base of the boot sole had to be adapted to the lower standard Width, because otherwise the sole would protrude over the ski, which is a disadvantage.
  • the guidance of the ski is deteriorated.
  • the object of this invention is to avoid these disadvantages.
  • the invention consists essentially in providing the sole base with a break at the outer edge and being straight at the inner edge, in such a manner having the greatest width in the region of the ball of the foot. It has been proved that the guidance of the ski is mainly done with the inner edge of the ski. For this reason it is important that the inner top edge of the ski aligns with the inner edge of the sole base. This is why the inner edge of the sole base is straight. On the outer edge it is not necessary for the sole and the ski to be in alignment, but it is enough if use is made of the entire supporting width.
  • the supporting width provided is greatest there.
  • a snow-plow-like shape is created by which the disturbances caused by the side base sections protruding over the ski edge are eliminated.
  • the invention has also the advantage of giving a greater stability when walking without skis because of its broader supporting area.
  • the front end width of the sole and the back end width of the sole are as wide or smaller than the smaller standard ski width (which is mm.) and the width at the break is as great or greater than the greater standard ski width (which is mm.).
  • the support is granted by the WhOle width of the ski, while when using skis of the smaller standard width only a snow-plow-like part of the sole base protrudes over the ski which is admissible.
  • the outer edge of the sole is broken. There can also be two breaks. In this case the greatest width of the ski stretches along a short distance along which the outer edge of the sole base is parallel with the inner edge of the sole base. In this case it is necessary, however, that the slanted edges enclose a greater angle with the longitudinal direction, even though this does not bring any advantage, because it is sufficient when the greater supporting width occurs just in one cross-section. Therefore, the sole base according to the invention is confined at its outer edge by two straight lines which meet in an angle at about the ball of the foot.
  • the inventive sole can be fabricated as an outer sole having the contour according to the invention and can be fixed to an intermediate sole of the ski boot by means of an adhesive.
  • the intermediate sole shows the contour of the inventive sole.
  • the inventive sole can also be made of one piece with the lower section of the upper or with a part of it. This is appropriate e.g. for ski boots of plastic or rubber.
  • the sole is formed unitary with the walls of a trough-like space enclosing the lower part of the upper on all sides, the upper being pinched (pulled) on the last using an insole.
  • any sort of quilt upper of leather or plastic and to adapt the shape of the shoe to the shape of a foot, still having the advantage of the inventive sole.
  • the part of the foot or the upper, respectively, extending over the sole can be supported by the space in which the lower part of the upper is positioned.
  • ski boots provided with an intermediate sole having conventionally the width of the foot can also be equipped with the inventive sole.
  • FIG. 1 shows schematically the shape of the sole
  • FIG. 2 is a view of the sole
  • FIG. 3 shows the cross-section along the line IIIIII of FIG. 2
  • FIG. 4 shows a section through the profile of the sole along the line IVIV of FIG. 2.
  • FIG. shows a cross-section through a ski boot provided with the inventive sole along the line V-V of FIG. 6, which in turn shows a longitudinal section through a ski boot along the line VI-VI of FIG. 5.
  • FIG. 7 shows a side view of the ski boot according to FIGS. 5 and 6.
  • FIG. 8 illustrates a cross section of a modification of the preferred embodiment shown in FIG. 2, said cross section being taken along a line corresponding to the line IIIIII in FIG. '2.
  • the inventive sole comprises a base 2 which is narrower than the shoe 3.
  • the base is confined by a straight edge 5, and at the outer side of the foot 6 it is confined by broken edges 7 and 8 which meet in the region of the ball in a point 9.
  • the base 2 is widest, and in the embodiment shown in the drawing this width equals the bigger standard width a of skis.
  • This standard Width which is shown in FIG. 1, is 70 mm.
  • the base protrudes beyond the smaller standard width of the ski, significated by b.
  • the shoe 3 fits, as FIG. 1 shows, 50 in the binding that the inner edge 5 aligns with the dash-dotted line, which represents the inner ski edge 10.
  • the break in the outer sole base edge 9 cuts olI with the outer edge of the ski 11A.
  • the breaking point 9 extends beyond the outer ski edge 11b. Consequently, the whole supporting sole base width is made use of when the bigger standard ski width a is used whilst when using the smaller standard ski width b the edge 7 acts snow-plow-like.
  • the width c at the back end of the sole 12 corresponds to the smaller standard ski width and the width a at the front end is smaller than this standard ski width. In this way, protruding of the front end of the boot sole base beyond the smaller standard ski width is prevented, even in case of incorrect fit in the bindings. It is also taken into account that there is hardly any burden on the toes and that the smaller width fits better to the foot.
  • the sole 1 is formed in one piece with the walls 20 of a cavity 16 which embrace the lower part of the upper 17 of the ski boot 3.
  • the upper 17 is pinched over the last using an insole 18.
  • the bottom wall 19 of the cavity is thicker than the walls 20 extending upwardly so that the bottom wall 19 supports the upper 17 and thus the foot,
  • the thinner walls 20 engage the upper 17 elastically.
  • the cross-section of these walls 20 tapers towards the upper rim 21.
  • the upper rim 21 of the walls is extended upwardly so that it lies in equidistance from the insole.
  • the top of the cavity 16 is about mm. to mm. higher than the bottom thereof.
  • the wall 24 is extended upwardly so that it forms a heel pad.
  • 25 is an insertion member, e.g. of plywood or similar material, which stiffens the sole 1 and lessens its weight.
  • the upper 17 put together with the insole 18 over the shoe last together with the shoe last is connected to a mould confining the outer surface of the sole 1 and the cavity 16.
  • the insertion member 25 is laid in, and plastic is sprayed into the mould.
  • the upper thus forming part of the mould is contacted by the plastic sprayed into the mould so that after hardening of the plastic the sole 1 and the walls of the cavity 16 are fixed to upper 17 and the insole 18.
  • recesses 26 in the insole 18, into which the plastic enters As is shown in FIG. 5, these recesses may be enlarged at the tops 27 thereof so that the protrusions formed by the plastic of the sole 1 and the bottom wall of the cavity 16 firmly engages the recesses 26.
  • the inventive sole 1 is constituted by an elevated middle zone of an outer sole which can be ahesively fixed to an intermediate sole of a ski boot 3.
  • This outer sole comprises border zones 28 extending from the middle zone, the border zones corresponding to the shape of the ski boot. Consequently, ski boots having a conventional intermediate sole can be equipped with the inventive sole.
  • the border zones 28 have a thickness a which is about 4 mm. to 5 mm. and the middle zone has a thickness b.
  • the thickness at is about /s through or about half of the thickness b of the middle zone.
  • This sole too, has grooves 14, 15, 36 for security against skidding.
  • a sole for a ski boot comprising a substantially rectangular base member of a width narrower than the upper of said boot and means attaching said base member to said upper, said base member being defined by two parallel relatively shorter edges forming the front and rear edges of said base member, respectively, the lengths of said front and rear edges being equal to or smaller than the width of a narrower standard width ski, an inner lateral edge forming a straight line longitudinally of said boot extending from said front edge to said rear edge and an outer lateral edge forming a line extending rearwardly of said front edge and outwardly of said boot and a line extending forwardly of said rear edge and outwardly of said boot, said lines converging at a point intermediate the length of said base member, the width of said base member at said point of convergence of said line being equal to or greater than the width of a wider standard width ski.
  • ski boot sole defined in claim 1 wherein said means for attachment is integral with a lower portion of said upper of said ski boot and is integral with said base member.
  • said means for attachment comprises means defining a cavity extending upwardly of said base member, said means defining a cavity being adapted to substantially encircle and grasp the lower portion of said upper of said ski boot and an insole clamping said lower portion of said upper to said base member.
  • said means for attachment includes a relatively stiff member extending longitudinally of said sole within said means for attachment for stiffening said sole and providing additional support for the human foot.
  • said means for attachment is a substantially flat rectangular member integral with said base member and of a width greater than said base member, said flat rectangular member being adapted to be adhesively attachable to an intermediate sole of said ski boot.
  • said base member includes a groove defined in the surface of 3239952 3/1966 Lange at said base member away from said boot upper, said groove ALFRED GUEST, Primary Examiner extending continuously parallel said front and rear edges and said lateral edges of said base member and spaced 10 U5, C1, X.R inwardly of said edges. 36-32
