Definitions

  • the present invention refers to an improved safety arrangement for ski boots and similar sports footwear, adapted to ensure the possibility for an upper shell hinged on the lower shell of the boot to pivot backwards in the case of violent backward stresses being imposed to the leg and, therefore, the upper shell that contains and closes it in.
  • a boot of this kind usually comprises, on the upper shell, two hem portions or flaps that open apart to allow for the foot to be introduced in the boot and removed therefrom.
  • the foot In order to be protected in an adequate manner, the foot must be fittingly and tightly closed in, especially by the upper shell when said hem portions or flaps thereof are closed.
  • the upper shells are usually rather high, since this is how the twofold advantage is obtained of both protecting the articulation of the ankle from any excessive stress that might be imposed thereon and, at the same time, facilitating an effective control of the lateral inclination of the boot, and therefore the ski, by only inclining the leg with respect to the ground, and no longer having to also incline the foot with respect to the leg.
  • an upper shell that is too rigid unavoidably gives rise to a number of well-known disadvantages both when the knee has to be inclined forwards with respect to the foot, this by the way being a basic movement that is performed repeatedly during skiing and does not admit any sensible resistance thereto, and in connection with the fact that, when the ski is removed upon concluding a downhill race, a too rigid upper shell would be of hindrance in walking.
  • the publication WO 97/22271 discloses a toggle-type arrangement that is adapted to enable the upper shell to change from a forward-inclined working position to a resting position in which the upper shell is capable of pivoting backwards.
  • another important purpose of the present invention is to provide a safety arrangement of the above-indicated kind which is adapted to enable the locking lever to automatically resume its working position when the leg moves back into its normal forward-inclined posture.
  • This safety arrangement shall furthermore be capable of being easily manufactured and operated at reasonably low costs with the use of readily available, largely known tools, materials and component parts.
  • an oscillating locking member or vertical lever, 4.
  • This member is joined in an articulated manner onto said lower shell by means of a second pin 5, which is provided in an intermediate position of said lever, and is oriented horizontally so as to enable said lever to protrude from the lower shell with either the upper arm 6 thereof or, alternatively, the lower portion 10 thereof.
  • This lever is biased by elastic means (not shown) into protruding with said portion 10 thereof from the body of the lower shell under resting conditions, i.e. when at rest (see Figure 1).
  • the upper edge of said lever 4 is constituted by an upper surface 7, which is arranged in a sensibly horizontal position when said lower portion 10 of the lever is retracted into said lower shell.
  • a locking member 8 is applied on said upper shell, above said vertical lever 4, and is provided with a lower surface 9 arranged preferably in a horizontal position.
  • said lower portion 10 When the boot is on the contrary mounted and fastened in the ski binding, as shown schematically in Figure 3, said lower portion 10 is pressed inwards and this causes the upper arm 6 of the lever 4 to move outwards and protrude in such a manner that the upper surface 7 thereof comes to face the lower surface 9 of said locking member 8, exactly therebelow, thereby preventing it, and therefore also the upper shell, from lowering.
  • said locking member 8 is attached firmly to the upper shell; according to the present invention, on the contrary, said locking member 8 is assigned an elongated shape, is arranged obliquely, i.e. sloping downwards, is adapted to pivotally turn about a third horizontal pin 11 and features an outer portion 12 that does not comprise said lower surface 9 that is located beneath the upper surface 7 (see Figure 4).
  • Said third pin is supported by an appropriate support means 15 which is firmly attached to said upper shell and shall be described in greater detail further on.
  • said locking member is provided with a working surface 13 that delimitates said portion 12 inwardly and that, therefore, extends with an angle downwards with respect to said lower surface 9, wherein the common corner 14 is located outwards (i.e. backwards) with respect to said lower surface 9.
  • a support means may be constituted by any means which, being firmly joined to the upper shell, is adapted to sustain said third pin 11 in the afore described position thereof.
  • a stop means is provided that is effective in limiting, at a pre-determined extreme position, the capability of said locking member 8 to turn under resting conditions thereof, i.e. when the upper shell is inclined forwards and, therefore, only the lower surface 9, and sometimes not even such a surface, is engaged against the upper surface 7 of the lever 4.
  • said stop means comprises a peg 17 adapted to engage appropriate perforations provided in said support means 15 and passing through an appropriate through-slot 18 provided in the locking member 8, as this is best illustrated in Figure 11.
  • a spiral spring 19 that works as a compression spring and is provided in a position between the lower portion 20 (containing the working surface 13) of the locking member 8 and a suitable wall 21, which is provided on the front side and above said locking member and preferably is an integral part of the structure of the support means 15, as shown in the Figures.
  • the arrangement itself is also provided with the possibility for said spring to be preloaded by means of an adjustable setting screw or bolt 22 rotating with an extreme thereof in an appropriate threaded hole provided in said wall 21, and with the other extreme thereof attached to the upper portion 29 of said spring 19 (see Figure 11).
  • the angle between the lower surface 7 and the working surface 13 of the locking member 8 should preferably be of approx. 90°.
  • a safe, reliable and convenient operation of the arrangement is obtained when the plane P1 that contains said pin 3 and said third pin 11 is sensibly close to the plane P2 that contains said pin 3 and said corner 14 between said lower surface 7 and said working surface 13 of the locking member 8.
