Abstract
An articulated ski boot for releasable attachment to a binding mounted on an alpine ski is presented. The ski boot has a sole which preferably is formed of first and second rigid portions with a hinge connecting the two portions such that the first portion is upwardly pivotable when the sole is free from the binding (walking mode). The boot has a substantially rigid boot upper adapted to receive a foot and which is attached to the sole. A truss member is pivotally connected to the boot upper and pivots between the walking mode and a locked skiing mode in which the sole portions are prevented from pivoting. The ski boot also includes means for securing the skier's forefoot and heel to the sole to substantially reduce toe and heel lift.
Claims16
A ski boot for releasable attachment to a binding mounted on an alpine ski, the boot comprising:
- a sole having a toe end and a heel end, the toe end having a portion to be releasably captured in the binding and the heel end having a portion to be releasably captured in the binding;
- a substantially rigid boot upper adapted to receive a foot, the boot upper including:
- a toe upper portion;
- a heel upper portion;
- and
- an inner bladder disposed within the toe and heel upper portions;
- and
- an inner bladder assembly to hold the foot on the ski boot sole, the assembly including:
- a first adjustable internal member disposed within the boot upper across a front portion of the inner bladder;
- a second adjustable internal member disposed within the boot upper across a rear portion of the inner bladder;
- a first device operatively connected to the first adjustable internal member for tightening and loosening the first adjustable internal member;
- a second device operatively connected to the second adjustable internal member for tightening and loosening the second adjustable internal member;
- wherein the first and second devices are disposed on exterior surfaces of the boot upper;
- and
- an articulated truss member having a first end and an opposing second end, the first end being pivotally connected to the toe upper portion such that the second end pivots between the first open position in which the second end is free of engagement with the heel upper portion and a second locked position in which the second end engages the toe heel portion and prevents pivotal movement of the toe upper portion and the first sole portion relative to the heel upper portion and the second sole portion.

A ski boot for releasable attachment to a binding mounted on an alpine ski, the boot comprising:
- a sole having a toe end and a heel end, the toe end having a portion to be releasably captured in the binding and the heel end having a portion to be releasably captured in the binding;
- a substantially rigid boot upper adapted to receive a foot, the boot upper including:
- a toe upper portion;
- a heel upper portion;
- and
- an inner bladder disposed within the toe and heel upper portions;
- and
- an inner bladder assembly to hold the foot on the ski boot sole, the assembly including:
- a first adjustable internal member disposed within the boot upper across a front portion of the inner bladder;
- a second adjustable internal member disposed within the boot upper across a rear portion of the inner bladder;
- a first device operatively connected to the first adjustable internal member for tightening and loosening the first adjustable internal member;
- a second device operatively connected to the second adjustable internal member for tightening and loosening the second adjustable internal member;
- wherein the first and second devices are disposed on exterior surfaces of the boot upper;
- and
- wherein the first adjustable internal member is attached to the first device by a pair of spaced first cables which are fitted through openings formed in the toe upper portion, the second adjustable internal member being attached to the second device by a pair of spaced second cables which are fitted through openings formed in the heel upper portion, and wherein each of the first and second devices includes a rotatable member to which at least one cable is attached and a ratchet mechanism operatively connected to the rotatable members for selectively winding or unwinding the at least one cable, thereby causing one of the first and second adjustable internal members to tighten or loosen.

A ski boot for releasable attachment to a binding mounted on an alpine ski, the boot comprising:
- a sole having a toe end and a heel end, the toe end having a portion to be releasably captured in the binding and the heel end having a portion to be releasably captured in the binding, the sole including:
- a substantially rigid first sole portion extending rearwardly from the toe end to a rear pivot end of the first sole portion;
- a substantially rigid second sole portion with a front pivot end adjacent to the rear pivot end of the first sole portion, the second sole portion extending from the front pivot end toward the heel end of the sole;
- and
- a hinge connecting the rear pivot end of the first sole portion to the front pivot end of the second sole portion such that the first sole portion is at least upwardly pivotable from a position in planar alignment with the second sole portion when the sole is free from the binding and the ski boot is in a first walking mode;
- a substantially rigid boot upper adapted to receive a foot, the boot upper including:
- a toe upper portion supported on the first sole portion;
- and
- a heel upper portion supported on the second sole portion;
- wherein the toe upper portion and the heel upper portion define between them a clearance in the boot upper permitting pivotal movement of the first sole portion relative to the second sole portion in the first walking mode;
- an articulated truss member pivotally connected to the toe upper portion and pivoting between the first walking mode and a second skiing mode in which the truss member lockingly engages the heel upper portion and prevents pivotal movement of the toe upper portion and the first sole portion relative to the heel upper portion and the second sole portion, thereby locking the first and second sole portions in planar alignment relative to each other;
- an inner bladder disposed within the toe and heel upper portions;
- and
- an inner bladder assembly to adjustably hold the foot on the ski boot sole, the assembly including:
- a first adjustable internal member disposed within the boot upper across a front portion of the inner bladder for preventing foot lift in said ski boot, thereby increasing ski control;
- a second adjustable internal member disposed within the boot upper across a rear portion of the inner bladder for preventing heel lift in said ski boot, thereby increasing ski control;
- a first device operatively connected to the first adjustable internal member for tightening and loosening the first adjustable internal member;
- a second device operatively connected to the second adjustable internal member for tightening and loosening the second adjustable internal member;
- and
- wherein the first and second devices are disposed on exterior surfaces of the boot upper.
