Definitions

  • the present application relates to a foot securing device, particularly for ski boots having a shell, a rear quarter and a front quarter.
  • knobs which are rotatably associated at the back of the rear quarter of the boot and has, at the end of its threaded stem which is internal to the quarter, a presser which interacts with a flap protruding from the shell.
  • Devices which are constituted by a threaded rod which can be actuated by the skier and with which a pawl is rotatably associated; said pawl has an inclined plane which interacts with a complementarily shaped inclined surface of a presser or flap arranged rearward with respect to the heel.
  • the aim of the present invention is therefore to eliminate the disadvantages described above in known types by providing a device which allows to achieve the optimum securing of the heel and of the foot inside the boot.
  • a further important object is to provide a device which allows to achieve the optimum securing of the heel of the foot by means of a single actuation.
  • Another important object is to provide a device which is structurally simple as well as reliable and safe in use.
  • Still another object is to provide a securing device which associates with the preceding characteristics that of allowing the removal of the foot from the boot while nonetheless keeping unchanged the degree of securing to be achieved when the boot is again worn.
  • a foot securing device particularly for ski boots having a shell, a front quarter and a rear quarter, comprising a threaded rod, a threaded pawl engaging said rod, and a first presser, said pawl having an inclined plane adapted to engage an inclined surface provided at said first presser, said rod having a longitudinal axis, said pawl being movable along said longitudinal axis upon rotation of said rod, to displace said first presser along a direction substantially perpendicular to said longitudinal axis, characterized in that it comprises at least one traction element having one end connected to said pawl, said traction element being adapted to embrace the foot instep region.
  • Said presser is advantageously constituted by a rear flap associated with the shell or with an inner shoe.
  • the reference numeral 1 indicates the front quarter of a ski boot which is associated, together with a rear quarter 2, with a shell 3.
  • the device comprises a threaded rod 4 which is associated with the rear quarter 2 and is arranged transversely thereto proximate to the rear surface 5.
  • Said threaded rod 4 has a first end 6 freely rotatably associated at an adapted seat 7 provided at a lug 8 which protrudes inside the rear quarter 2.
  • the second end 9 of the threaded rod 4 furthermore protrudes laterally and externally to the rear quarter 2, and an eccentric lever 10 actuatable by the skier is rotatably associated with said second end.
  • the threaded rod 4 can therefore move along its axis upon the actuation of the eccentric lever, while its first end 6 is biased within the seat 7 by a spring 11, preferably arranged coaxially to the second end 9 between the internal surface 12 of the rear quarter 2 and an annular flange 13 provided on the threaded rod 4 proximate to the second end 9.
  • the eccentric lever 10 thus defines two positions: a released position, shown in figure 1, wherein the end 6 of rod 4 is completely inserted in the seat 7; and a securing position, shown with dashed lines in figure 1, wherein the rod 4 is moved towards the right, with reference to the figure, of a length corresponding to the eccentricity of the lever 10.
  • a threaded pawl 14 is associated with the threaded rod 4 and has an inclined plane 15 at its side facing the foot.
  • the pawl 14 cannot rotate and only moves along the axis of the threaded rod 4, upon rotation of the same rod 4.
  • Said inclined plane 15 engages an inclined surface 16 provided at the rear presser or flap 17 which is associated with the shell 3 or with an inner shoe, at the heel region of the foot.
  • the end of at least one traction element is associated with the pawl 14; said traction element comprises a cable 18 which extends on the opposite side with respect to the eccentric lever 10 and is guided by a first guide 19 rigidly associated with the internal surface 12 of the rear quarter 2 and is then partially contained within a sheath 20 up to a second guide 21 associated with the shell 3.
  • the cable 18 passes through a first opening 22 which is provided laterally to the shell 3, then has a portion 23 which embraces a foot presser 26 at the foot instep region exits outside the shell through a second opening 25 provided laterally to said shell and is locked by means of an adapted rivet 24.
  • a clamp-like securing of the skier's foot is thus obtained and can be adjusted by rotating the eccentric lever 10 so as to achieve the best possible securing.
  • the sheath 20, between the guide 19 associated with the rear quarter 2 and the guide 21 associated with the shell 3, allows to open the quarter, and in particular the rear quarter 3, which otherwise would be locked by the tensioned cable 18.
  • Figure 1 shows in dashed lines the securing position of the lever 10; to release the foot, it is simply necessary to flip the lever in the released position, shown in full lines in figure 1 without rotating the rod 4 to move the pawl 14 with respect to the rod.
  • the selected securing strength is "stored" by the device: it is in fact necessary to simply flip back the lever 10 in the securing position (shown in dashed lines) to obtain the previously selected degree of securing.
  • the invention has achieved the intended aim and objects, a device having been provided which allows to achieve an optimum securing of the foot inside the boot by virtue of a combination of the tensioning of a cable and the movement of a flap to lock said foot in a clamp-like manner.
  • the device is furthermore simple and rapid to adjust according to each skier's specific requirements and is structurally very simple.
  • the configuration of the device furthermore allows, by moving the rear quarter backward, an easy extraction of the foot, releasing the heel; the device furthermore "stores" the selected degree of securing, allowing to open and close the quarter with no need to perform the securing adjusting each time.
