Definitions

  • the present invention relates to a ski boot.
  • the present invention relates to a ski mountaineering boot, use to which the following description will make explicit reference without however losing generality.
  • the ski mountaineering boots currently on the market basically comprise: a rigid shell made of plastic or composite material, which is shaped so as to accommodate the foot of the user and has a lower part specifically structured to be fastened to the back of a downhill ski or the like by means of a suitable ski mountaineering binding device; and a rigid cuff made of plastic or composite material, which is shaped so as to embrace the lower part of the leg of the user from behind, and is hinged to the upper part of the shell so as to be able to rotate about a transversal reference axis, which is substantially perpendicular to the midplane of the boot and is also locally substantially coincident with the articulation axis of the ankle.
  • ski mountaineering boots also comprise: an innerboot made of soft and heat-insulating material, which is inserted in the shell and the cuff and is shaped so as to accommodate and protect both the foot and the lower part of the leg of the user; and a set of manually operated locking members which are located both on the shell and the cuff, and are structured so as to be able to selectively close/tighten the shell and the cuff to firmly immobilize the leg of the user inside the innerboot.
  • ski mountaineering boots are provided with a manually-operated cuff-locking device which is traditionally located in the area above the heel of the boot, and is structured so as to be able to, selectively and alternately, lock the cuff to the shell in a rigid manner for preventing any pivoting movement of the cuff on the shell, and completely release the cuff from the shell for allowing the cuff to freely pivot on the shell.
  • a manually-operated cuff-locking device which is traditionally located in the area above the heel of the boot, and is structured so as to be able to, selectively and alternately, lock the cuff to the shell in a rigid manner for preventing any pivoting movement of the cuff on the shell, and completely release the cuff from the shell for allowing the cuff to freely pivot on the shell.
  • the cuff locking device is made up of a coupling arm which is butt-hinged to the cuff above the heel, so as to be able to move on the midplane of the boot between a lowered position in which the arm firmly couples to the shell so as to prevent any pivoting movement of the cuff on the shell, and a raised position in which the arm does not couple to the shell and therefore allows the cuff to freely pivot on the shell.
  • the coupling arm in the lowered position the coupling arm generally extends downwards skimming the heel of the ski boot, so that the distal end of the arm can firmly couple at a specific point of the shell thus to lock the cuff to the shell in a predetermined position.
  • the coupling arm is moreover connected to a closing cable that is looped around the cuff, so that the movement of the coupling arm into the lowered position can tighten the closing cable to such an extent as to tighten the cuff firmly against the leg of the user.
  • the user can, in fact, vary the grip exerted by the closing cable on the cuff only by manually adjusting the length of the cable. This operation is particularly long and laborious and proves to be impractical during competitions, with all the problems that this entails.
