Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
148 words
A ski boot device for facilitating walking, comprising a profiled member for connection to a sole of a ski boot at an instep seat located between a front portion of said sole and a heel portion of said sole, said profiled member being mobile between a first position in which it is in line with a bottom plane of said sole, and a second position in which it at least partly projects beyond said bottom plane of said sole, wherein said heel portion of said sole has an appendix projecting into said instep seat and said profiled member comprises a stirrup element having a widened U-configuration and two arms having free ends pivotally connected to said appendix for rotation about an axis substantially parallel to said bottom plane of said sole and perpendicular to said appendix, and wherein said stirrup element and said sole have an equal width.
Claim 2
Dependent Claim
148 words
A ski boot device for facilitating walking, comprising a profiled member for connection to a sole of a ski boot at an instep seat located between a front portion of said sole and a heel portion of said sole, said profiled member being mobile between a first position in which it is in line with a bottom plane of said sole, and a second position in which it at least partly projects beyond said bottom plane of said sole, wherein said heel portion of said sole has an appendix projecting into said instep seat and said profiled member comprises a stirrup element having a widened U-configuration and two arms having free ends pivotally connected to said appendix for rotation about an axis substantially parallel to said bottom plane of said sole and perpendicular to said appendix, and wherein said stirrup element and said sole have an equal width.
Claim 3
Dependent Claim
44 words
A ski boot device as claimed in claim 1, wherein said free ends of said arms of said stirrup element have a cam configuration for co-operation with said instep seat such that said first and second position define stable positions for said stirrup element.
Claim 4
Dependent Claim
140 words
A ski boot device for facilitating walking, comprising a profiled member for connection to a sole of a ski boot between a front portion of said sole and a heel portion of said sole, wherein said profiled member comprises a substantially cylindrical element housed in a seat provided in said sole between said front portion and said heel portion and rotatable about a pin substantially perpendicular to a base of said seat, said cylindrical element having a geometric axis and a lower face substantially perpendicular to said geometric axis and an upper face inclined with respect to said geometric axis, said cylindrical element being selectively positionable in a first position in which said lower face is in line with said sole, and in a second position in which at least a part of said cylindrical element projects beyond said sole.
Claim 5
Dependent Claim
140 words
A ski boot device for facilitating walking, comprising a profiled member for connection to a sole of a ski boot between a front portion of said sole and a heel portion of said sole, wherein said profiled member comprises a substantially cylindrical element housed in a seat provided in said sole between said front portion and said heel portion and rotatable about a pin substantially perpendicular to a base of said seat, said cylindrical element having a geometric axis and a lower face substantially perpendicular to said geometric axis and an upper face inclined with respect to said geometric axis, said cylindrical element being selectively positionable in a first position in which said lower face is in line with said sole, and in a second position in which at least a part of said cylindrical element projects beyond said sole.
Claim 6
Dependent Claim
27 words
A ski boot device as claimed in claim 3, wherein said base of said seat has an inclination conjugate with the inclination of said inclined upper face.
Claim 7
Dependent Claim
57 words
A ski boot device as claimed in claim 3, further comprising means for selectively maintaining said cylindrical element in said first and second position, said means comprising projections on said base of said seat diametrically opposite with respect to said pin and cavities correspondingly provided in said upper face of said cylindrical element for receiving said projections.
Claim 8
Dependent Claim
28 words
A ski boot device as claimed in claim 3, wherein said first and said second position of said cylindrical element are angularly spaced by 180° about said pin.
Claim 9
Dependent Claim
25 words
A ski boot device as claimed in claim 3, wherein said cylindrical element comprises scoring on said lower face to act as a friction element.
Claim 10
Dependent Claim
22 words
A ski boot device as claimed in claim 3, wherein said seat is open laterally to facilitate access to said cylindrical element.
Claim 11
Dependent Claim
30 words
A ski boot device as claimed in claim 3, wherein said cylindrical element comprises a lateral face and ribs on said lateral face to facilitate gripping of said cylindrical element.
Claim 12
Dependent Claim
20 words
A ski boot device as claimed in claim 3, further comprising a metal stiffening disc embedded into said cylindrical element.
Claim 13
Dependent Claim
58 words
A ski boot device as claimed in claim 3, wherein said cylindrical element and said pin are arranged on said sole in a position such that when the user's body is in an upright position, the user's weight acts at a point lying between said cylindrical element and a rear end of said heel portion of said sole.
