Abstract
Abstract A boot, particularly a ski boot, is provided with device for retaining the foot against both lateral and vertical movement. The device comprises a generally V-shaped support element having two deformable side plates which can be adjusted for gripping movement toward and away from the foot. The plates have a shape generally corresponding to that of the top of the forefoot, and thus distribute the gripping stresses over the entire surface of the top of the foot, obviating painful pressure spots. The means for adjusting the position of the side plates is controlled from the exterior of the boot. A rapid tightening-untightening arrangement can also be incorporated into the boot according to the invention.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
150 words
A boot comprising (a) a rigid shell; (b) a foot retention system mounted on the interior of the shell in the area of the forefoot, said foot retention system comprising (i) a support means, independent of the sole of the boot and having a generally V-shape, comprising two side plates extending laterally and upon the upper part of the forefoot, having a shape corresponding substantially to the anatomy of said forefoot at its widest point; and (ii) an adjustable means for clamping said support means against a foot within said boot, comprising means for simultaneously moving said two side plates and pressing them against said foot while adapting them to the anatomy of the upper part of the forefoot, said clamping means being supported on said shell in such manner that said foot is clamped against the inner sole of said boot and is laterally maintained by said support means.
Claim 2
Dependent Claim
150 words
A boot comprising (a) a rigid shell; (b) a foot retention system mounted on the interior of the shell in the area of the forefoot, said foot retention system comprising (i) a support means, independent of the sole of the boot and having a generally V-shape, comprising two side plates extending laterally and upon the upper part of the forefoot, having a shape corresponding substantially to the anatomy of said forefoot at its widest point; and (ii) an adjustable means for clamping said support means against a foot within said boot, comprising means for simultaneously moving said two side plates and pressing them against said foot while adapting them to the anatomy of the upper part of the forefoot, said clamping means being supported on said shell in such manner that said foot is clamped against the inner sole of said boot and is laterally maintained by said support means.
Claim 3
Dependent Claim
54 words
A boot according to claim 1, wherein said means for simultaneously moving said two side plates of said support means comprise means for moving said side plates in opposite directions substantially transversely to the longitudinal axis of said foot, said two side plates being movably mounted substantially transversely on said shell and being independent.
Claim 4
Dependent Claim
82 words
A boot according to claim 2, wherein said means for simultaneously moving said two side plates of said support means comprises (a) two threaded holes respectively solid with each of said two side plates; (b) a screw mounted transversely on said rigid shell, movable by rotation about its axis and comprising two portions threaded in opposite directions each screwed in one of said two holes; and (c) a control means accessible from the exterior of said rigid shell for turning said screw.
Claim 5
Dependent Claim
61 words
A boot according to claim 2, wherein said means for simultaneously moving said two side plates in opposite directions comprises two pressure elements movably mounted transversely of said rigid shell and each respectively abutting against an inclined ramp solid with the corresponding side plate, and means for actuating said pressure elements from the exterior for transverse translation movement in opposite directions.
Claim 6
Dependent Claim
40 words
A boot according to claim 1, wherein said means for simultaneously moving said two side plates comprises means for moving each said side plate in a directions substantially orthogonal to the lateral surface corresponding to the top of said foot.
Claim 7
Dependent Claim
83 words
A boot according to claim 5, wherein said means for moving each said side plate in a direction substantially orthogonal to the lateral surface corresponding to the top of said foot comprises two pressure elements movably mounted transversely of said rigid shell and each respectively abutting against an inclined ramp solid with the corresponding side plate, and means for actuating said pressure elements from the exterior for transverse translation movement in opposite directions, said two side plates being connected in a flexible manner.
Claim 8
Dependent Claim
80 words
A boot according to claim 4 or 6, wherein said means for actuating said pressure elements from the exterior comprises: (a) two threaded holes respectively solid with each of said two pressure elements; (b) a screw mounted on said rigid shell movable by rotation about its axis and comprising two portions threaded in opposite directions, each screwed in one of said two holes; and (c) a control means accessible from the exterior of said rigid shell for turning said screw.
Claim 9
Dependent Claim
34 words
A boot according to claim 1, wherein said clamping means further comprises resilient which actuate said support element in such manner as to separate said two side plates while unclamping them from the foot.
Claim 10
Dependent Claim
23 words
A boot according to claim 1, wherein said clamping means further comprises manual means for rapid tightening and loosening of said clamping means.
Claim 11
Dependent Claim
147 words
A boot according to claim 9 wherein said means for simultaneously moving said two side plates of said support means comprises two threaded holes respectively solid with each of said two side plates; a screw mounted transversely on said rigid shell, movable by rotation about its axis and comprising two portions threaded in opposite directions each screwed in one of said two holes; and a control means accessible from the exterior of said rigid shell for turning said screw; and wherein a first one of said two portions threaded in opposite directions is movably mounted for translation movement with respect to the second one of said plates along the axis of said screw, said means for rapid tightening and loosening of said clamping means comprising a lever on the exterior of said boot for actuating said two threaded portions for translation movement with respect to one another.
Claim 12
Dependent Claim
19 words
A boot according to claim 1 to 10, wherein said clamping means is in lateral abutment against said shell.
Claim 13
Dependent Claim
