Definitions

  • the present invention relates to a foot securing device, particularly for ski boots as mentioned in the precharacterising part of claim 1.
  • Some known systems provide a good adjustment of the pressure on the foot, even if by means of complicated devices, but this pressure is often constant both during the flexing phase and during the extension and resting phase.
  • WO-A-81/01645 shows a foot securing device according to the precharacterising part of claim 1 comprising a ski boot with a pair of foot instep engaging strap members and a lower leg-engaging element which comprises a pair of rigid arm members extending on the opposite sides of the foot and a shin-engaging shaped section interconnected between respective ends of the rigid arm members.
  • the bottom ends of the rigid arm members are pivotally connected to the ski boot along with a pulley member, and a cable element is interconnected between such pulley member and the foot instep engaging strap members.
  • the aim of the present invention is therefore to eliminate the disadvantages described above in known types by providing a device which exerts a pressure on the foot which is adapted to the variable conditions of use of the boot.
  • a particular object of the invention is to provide a device which is simple to use and easy to manufacture, and therefore advantageous from an economic point of view.
  • a ski boot comprises a shell 1 whereto are connected, in a per se known manner, a front quarter 2 and a rear quarter 3.
  • a movable element is arranged in a depressed region of the front upper border of the front quarter, and is composed of a movable element or front upper quarter 6 which is oscillable with respect to the front quarter 3.
  • the upper front quarter 6 can, for example, be pivoted by means of the pivot 7 to the front region of the quarter 6 and has elongated slots 8 engaged by respective pins 9 fixed to the sides of the front quarter.
  • the upper front quarter 6 can be connected to the front quarter 2 even by means of other different systems, for example as described in the U.S. patent application serial No. 07/036519, filed by the same Applicant.
  • the upper front quarter 6 is oscillable with respect to the front quarter 3 along a transverse axis which passes through the pivot 7.
  • the device further consists of a pressure plate 10b, pivoted in a per se known manner to the shell 1 or freely slideable, arranged inside said shell at the foot instep and preferably outside the inner boot with which ski boots are normally provided.
  • a cable 11a located inside the boot, acts on the pressure plate 10b and extends above the plate 10b embracing it transversely with respect to its longitudinal extension.
  • Said cable 11a which is guided by means of a lower guide element 12 and of an upper guide element 13, extends along the lateral region of the boot and protrudes from the slot 14 proximate to the upper front quarter 6, embracing it on the outer side.
  • the guide elements 12 and 13 can be constituted by pulleys or similar means fixed to the inside of the boot.
  • the lower guide elements 12 consist of pulleys arranged at pivots for the pivoting of the quarters with respect to the shell; while the upper guide elements 13 each expediently consist of a shaped raised portion provided on the inner surface of the sides of the front quarter 2.
  • the two lower guide elements 12 are preferably arranged downwardly with respect to the pressure plate 10b so that the cable 11a, which extends above the plate 10b, can act on said plate and press on the foot.
  • the guide elements 12 and 13 be positioned so that an inclination of the upper front quarter 6 is matched by an increase in the length of the cable between a point defined on the outside of the upper front quarter and the guide elements 12 or 13.
  • Said point can consist, for example, of a notch 17 provided transversely on the front outer surface of the upper front quarter 6 which accommodates the external portion of the cable 11a.
  • an adjustment element 15 for the adjustment of the working length of said cable is provided, and in this case is advantageously located on a side of the front quarter 2. Said element 15 follows the excursion of the cable during the flexing phase and is therefore movable with respect to the quarter.
  • the element 15 can be furthermore provided by known means, such as for example a cylinder 15a with counterposed threads which engage threaded ends 15b of the cable 11, slideable in a slot 16 provided on the front quarter so that the cylinder 15a is manually rotatable from the outside.
  • known means such as for example a cylinder 15a with counterposed threads which engage threaded ends 15b of the cable 11, slideable in a slot 16 provided on the front quarter so that the cylinder 15a is manually rotatable from the outside.
  • the adjustment element 15 besides performing a fine adjustment of the tension of the cable 11, allows a sufficient slackening of said cable to facilitate the operation of putting on the boot.
  • the position of the cable 11 on the outer side of the upper front quarter 6, can be advantageously ensured by means of a series of notches 17 provided transversely with respect to said upper front quarter.
  • Said plurality of notches 17 allow an approximate adjustment of the tension of the cable.
  • the pressure plate 10a can be arranged at the heel of the foot by obtaining it, for example, out of the inner shoe or out of the shell of said boot.
  • the structure of the device, with the plate 10a at the heel, is such that the pressure is exerted on the heel.
  • the device is characterized in that it comprises two pressure plates which act simultaneously on the foot.
  • a pressure plate 10b is located at the foot instep, pivoted to the shell or freely slideable, while a pressure plate 10c is located at the heel and can expediently be defined by the inner shoe or by the shell of the boot.
  • the cable 11a is advantageously fixed at one end, for example by means of an eyelet, to a first point 18 located inside the shell 1 and arranged downwardly and laterally with respect to the region of location of said pressure plate 10b and extends transversely above said plate with respect to its longitudinal extension.
  • the cable 11a is fixed, in a similar manner, to a second point 19 arranged inside the shell and located frontally and laterally with respect to the region of location of said pressure plate 10c.
  • the cable 11a extends along the sides of the quarter of the boot by means of the lower guide element 12 and the upper guide element 13 on one side and by means of the lower guide element 12a and the upper guide element 13a on the other side, and protrudes out of the slots 14a and 14b, arranged symmetrically proximate to the front quarter, extending on the outer side of said quarter.
  • An adjustment element 15 for the adjustment of the working length of the cable is advantageously arranged in the lateral region of the boot for permitting the fine adjustment of the tension of the cable.
  • each of the devices described above is substantially similar: during the leg flexing phase there is an increase in the distance between the upper guide elements 13 and the point 14 defined on the upper front quarter where the cable 11 is accommodated.
  • the initial pressure is restored by virtue of the elastic return of the cable.
  • the pressure on the foot depends on the inclination of the upper front quarter with respect to the front quarter and therefore on the inclination of the leg.
  • the graph of fig. 5 shows the pressure on the foot during the flexing, extension and rest phases.
  • the device is characterized in that the cable 11 is caused to pass, inside the boot 1, beneath an insole 20 which can be interposed between the base of the shell 1 and the inner shoe 21, the insole 20 being movable and acting on the foot as a presser.
  • the materials employed which are preferably those conventionally used in the manufacture of ski boots, as well as the dimensions and the contingent shapes, may be any according to the specific requirements.
