Abstract
Abstract The foot securing device comprises a cable which extends partially inside a boot and is guided by means of guide elements to act on a foot presser. The boot has a front quarter connected to a shell, and an upper front quarter connected to an upper portion of the front quarter. The cable extends over the upper front quarter so as to act on the presser according to the movement of the upper front quarter with respect to the quarter.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
233 words
In a ski boot having a front quarter and a rear quarter pivotally associated with a shell, a foot securing device comprising: a movable element arranged for abuttment against a front portion of a skier's lower leg; means for movably mounting said movable element on said front quarter; at least one presser arranged inside said shell for exerting a clamping action on a skier's foot; at least one cable for operatively connecting said movable element to said at least one presser; wherein said means for movably mounting said movable element to said front quarter comprises oscillating means allowing substantially continuous oscillation of said movable element with respect to said front quarter in both forward and backward direction about an oscillation axis extending transversely of said front quarter, said at least one cable extending from a location of said movable element remote from said oscillation axis along a direction at least partially towards said skier's lower leg and extending away from said at least one presser along a direction at least partially towards said skier's foot, whereby said at least one presser is caused to automatically move towards and away from said skier's foot in response to a forward and backward oscillation of said movable element to thereby provide a continuous and proportional variation in said clamping action on said skier's foot upon corresponding increase in flexing of said skier's lower leg during skiing.
Claim 2
Dependent Claim
233 words
In a ski boot having a front quarter and a rear quarter pivotally associated with a shell, a foot securing device comprising: a movable element arranged for abuttment against a front portion of a skier's lower leg; means for movably mounting said movable element on said front quarter; at least one presser arranged inside said shell for exerting a clamping action on a skier's foot; at least one cable for operatively connecting said movable element to said at least one presser; wherein said means for movably mounting said movable element to said front quarter comprises oscillating means allowing substantially continuous oscillation of said movable element with respect to said front quarter in both forward and backward direction about an oscillation axis extending transversely of said front quarter, said at least one cable extending from a location of said movable element remote from said oscillation axis along a direction at least partially towards said skier's lower leg and extending away from said at least one presser along a direction at least partially towards said skier's foot, whereby said at least one presser is caused to automatically move towards and away from said skier's foot in response to a forward and backward oscillation of said movable element to thereby provide a continuous and proportional variation in said clamping action on said skier's foot upon corresponding increase in flexing of said skier's lower leg during skiing.
Claim 3
Dependent Claim
61 words
A device according to claim 1, wherein said movable element comprises a substantially curved plate with a rear concave surface substantially conforming to the front portion of said skier's lower leg and with a front convex surface at least partially protruding from a substantially complementary shaped vane extending from the upper border of said front quarter at least partially downwardly thereof.
Claim 4
Dependent Claim
44 words
A device according to claim 1, wherein said oscillation axis is located proximate to the lower end of said movable element adjacent to the lower edge of said movable element adjacent to the lower edge of said complementary shaped vane of said front quarter.
Claim 5
Dependent Claim
34 words
A device according to claim 1, wherein said front surface of said movable element is provided with at least one notch for the accomodation of a connecting portion of said at least one cable.
Claim 6
Dependent Claim
18 words
A device according to claim 1, wherein said at least one cable is provided with length adjusting means.
Claim 7
Dependent Claim
59 words
A device according to claim 1, wherein said length adjusting means comprises a cylindrical body having an axially extending hole provided with counterthreaded ends, said counterthreaded ends engaging with complementary threaded end portions of said at least one cable to provide oppositely directed displacement on said cable end portions on rotation of said cylindical body about its rotation axis.
Claim 8
Dependent Claim
28 words
A device according to claim 1, wherein said front quarter has a lateral cavity arranged for rotatably supporting said cylindrical body in an accessible position from the outside.
Claim 9
Dependent Claim
35 words
A device according to claim 1, wherein said at least one presser comprises a first presser located inside said shell proximate to the foot instep portion thereof and actuatable by said at least one cable.
Claim 10
Dependent Claim
28 words
A device according to claim 1, comprising a second presser located inside said shell proximate to the heel portion thereof and actuatable by said at least one cable.
Claim 11
Dependent Claim
29 words
A device according to claim 1, wherein said presser located proximate to said heel portion is solid with an inner shoe or is an inner part of said shell.
Claim 12
Dependent Claim
49 words
A device according to claim 1, comprising a first presser located inside said shell proximate to the foot instep thereof and a second presser located inside shell proximate to the heel portion thereof, said first and said second foot presser being both actuatable by said at least one cable.
Claim 13
Dependent Claim
45 words
A device according to claim 1, further comprising means for guiding said at least one cable inside said shell so that said at least one cable overrides at least partially said at least one presser from the outer side thereof opposite to the skier's foot.
Claim 14
Dependent Claim
16 words
A device according to claim 1, wherein said at least one cable is substantially continuous loop.
Claim 15
Dependent Claim
48 words
A device according to claim 1, wherein there is provided a third presser comprising a movable insole interposed between the inner base surface of said shell and an inner shoe, said at least one cable passing beneath said movable insole to force it upwardly against said inner shoe.
