Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
144 words
An injection molded ski-boot of plastics, and preferably thermoplastics material, said boot comprising: a rigid upper; a rigid sole and heel integral with the upper; a collar surrounding the top of the upper, effective a U-shaped reinforcement; a horizontal base on said reinforcement which extends through the sole near the heel; limbs on the reinforcement which extend towards the top of the boot, said limbs being each situated at the rear of the boot, and which bear firmly against a major portion of the rear of the upper of the boot, one on each side of the longitudinal centre-line of the boot; and an upper arm on each limb, each upper arm being secured at a free end near to the top of the rear of the upper; and means on each side of the upper for adjustment of the position of the limbs.
Claim 2
Dependent Claim
144 words
An injection molded ski-boot of plastics, and preferably thermoplastics material, said boot comprising: a rigid upper; a rigid sole and heel integral with the upper; a collar surrounding the top of the upper, effective a U-shaped reinforcement; a horizontal base on said reinforcement which extends through the sole near the heel; limbs on the reinforcement which extend towards the top of the boot, said limbs being each situated at the rear of the boot, and which bear firmly against a major portion of the rear of the upper of the boot, one on each side of the longitudinal centre-line of the boot; and an upper arm on each limb, each upper arm being secured at a free end near to the top of the rear of the upper; and means on each side of the upper for adjustment of the position of the limbs.
Claim 3
Dependent Claim
66 words
A ski-boot as claimed in claim 1, in which the means for adjustment of the limbs comprises: means defining the recesses symmetrical in relation to and on either side of the longitudinal centre-line of the boot; two channelled parts each having means defining a radial groove for receiving a lower arm of said limbs, each of said recesses being adapted to receive the corresponding channelled part.
Claim 4
Dependent Claim
34 words
A ski-boot as claimed in claim 2, in which the groove has a reduced portion, the width of which corresponds substantially to the diameter of the lower arms of the limbs of the reinforcement.
Claim 5
Dependent Claim
26 words
A ski-boot as claimed in claim 2, in which the channelled part is of slightly frusto-conical shape so that it can be clipped into the recess.
Claim 6
Dependent Claim
23 words
A ski-boot as claimed in claim 1, and further comprising means for adjustment of the positioning of said horizontal base at the sole.
Claim 7
Dependent Claim
70 words
A ski-boot as claimed in claim 5, in which the means for adjustment has a transverse portion defining a recess in the sole which extends from one side of the boot to the other, in front of the heel, in which recess is lodged a member which forms a wedge and in which there is means defining a longitudinal notch for the base of the reinforcement to be passed therethrough.
Claim 8
Dependent Claim
38 words
A ski-boot as claimed in claim 6, in which the transverse recess is of substantially cylindrical shape and comprises a flat substantially perpendicular to the direction in which the lower arms of the limbs of the reinforcement extend.
Claim 9
Dependent Claim
41 words
A ski-boot as claimed in claim 6, in which the member which forms a wedge further comprises a clipping channel in which can be lodged an upstanding portion situated in the longitudinal centre-line of the boot and within the transverse recess.
Claim 10
Dependent Claim
36 words
A ski-boot as claimed in claim 1, and further comprising means for keeping the ends of the upper arms of the limbs in position near the top of the rear of the upper of the boot.
Claim 11
Dependent Claim
36 words
A ski-boot as claimed in claim 9, in which the means for holding the upper arms in position comprises a bent sheet-metal part adapted to slide along the upper arms of the limbs of the reinforcement.
Claim 12
Dependent Claim
36 words
A ski-boot according to claim 10, in which the bent sheet-metal part further comprises, at its centre, an opening adapted to form a passage for a resilient button connected to the rear end of the upper.
Claim 13
Dependent Claim
29 words
A ski-boot as claimed in claim 1, in which the angle of inclination of each upper arm with respect to its corresponding lower arm is between 30° and 70°.
Claim 14
Dependent Claim
53 words
A ski-boot as claimed in claim 1, and further comprising an integral boss located at the top portion of the rear of the upper, and means defining an oblong hole being cut into said boss, the free end of each of the upper arms of the limbs being lodged in said oblong hole.
Claim 15
Dependent Claim
23 words
A ski-boot as claimed in claim 1, in which the collar is fitted in the gap formed between the reinforcement and the upper.
Claim 16
Dependent Claim

A ski-boot as claimed in claim 1, and further comprising an oblique seating at the rear of the boot which is adapted to receive the lower arms of the limbs of the reinforcement.
Claim 17
Dependent Claim
128 words
In a ski-boot of the type having a rigid upper, a rigid sole and heel and a collar, an improved adjustment mechanism comprising: a continuous member having a lower base portion approximately equal in length to the width of the heel and a pair of limb portions extending from the ends of said base, said limbs having a contour following the exterior of the boot from the heel, along the sides of the boot upper and upwardly along the rear of the boot upper in a generally parallel relation; means on the heel of the boot for receiving said base; guide means on the sides of the upper for locating said limbs; and means for securing the parallel portion of said limbs to the rear of the upper.
Claim 18
Dependent Claim
128 words
In a ski-boot of the type having a rigid upper, a rigid sole and heel and a collar, an improved adjustment mechanism comprising: a continuous member having a lower base portion approximately equal in length to the width of the heel and a pair of limb portions extending from the ends of said base, said limbs having a contour following the exterior of the boot from the heel, along the sides of the boot upper and upwardly along the rear of the boot upper in a generally parallel relation; means on the heel of the boot for receiving said base; guide means on the sides of the upper for locating said limbs; and means for securing the parallel portion of said limbs to the rear of the upper.
Claim 19
Dependent Claim
26 words
A ski-boot as claimed in claim 16 wherein said means on the heel is movable to adjust the position of said base thereby adjusting the advance.
Claim 20
