US3909026A — Releasable safety device for a ski boot

Claim 1

Independent Claim 185 words

A releasable safety fixing device for a ski boot comprising: first holding means for holding one of the extremities of said boot, said first holding means including: first retaining means consisting of an abutment mounted to a ski, said first abutment having a first ramp; a second ramp mounted to said boot extremity and co-operating with said first ramp; second holding means for holding the other extremity of said boot including second retaining means co-operating with said other boot extremity; resilient means received in at least one of said holding means; said first and second ramps being slidable relative to one another, when subjected to a vertical force, along an axis corresponding substantially to the axis of said ski and against the opposing action of said resilient means; release means interposed between said resilient means and one of said holding means for disengaging said resilient means from said one holding means and from said boot extremity associated with said one holding means when said first and second ramps have slid one relative to the other a distance less than the maximum travel of said ramps.

Claim 2

Dependent Claim 185 words

A releasable safety fixing device for a ski boot comprising: first holding means for holding one of the extremities of said boot, said first holding means including: first retaining means consisting of an abutment mounted to a ski, said first abutment having a first ramp; a second ramp mounted to said boot extremity and co-operating with said first ramp; second holding means for holding the other extremity of said boot including second retaining means co-operating with said other boot extremity; resilient means received in at least one of said holding means; said first and second ramps being slidable relative to one another, when subjected to a vertical force, along an axis corresponding substantially to the axis of said ski and against the opposing action of said resilient means; release means interposed between said resilient means and one of said holding means for disengaging said resilient means from said one holding means and from said boot extremity associated with said one holding means when said first and second ramps have slid one relative to the other a distance less than the maximum travel of said ramps.

Claim 3

Dependent Claim 167 words

A release safety fixing device for a ski boot comprising: first holding means for holding one of the extremities of said boot, said holding means including an abutment mounted to a ski and provided with a first inclined ramp; said first inclined ramp co-operating with a second inclined ramp mounted to said boot extremity; second holding means for holding the other extremity of said boot, said second holding means including retaining means co-operating with said other boot extremity, resilient means producing an opposing action against which said first and second ramps slide one relative to the other along an axis corresponding substantially to the axis of said ski when subjected to a vertical force, and release means located between said resilient means and said retaining means for disengaging said resilient means from said retaining means and from the boot extremity associated with said retaining means when said second ramp has slid with respect to said first ramp a distance less than the maximum travel of said ramps.

Claim 4

Dependent Claim 167 words

A release safety fixing device for a ski boot comprising: first holding means for holding one of the extremities of said boot, said holding means including an abutment mounted to a ski and provided with a first inclined ramp; said first inclined ramp co-operating with a second inclined ramp mounted to said boot extremity; second holding means for holding the other extremity of said boot, said second holding means including retaining means co-operating with said other boot extremity, resilient means producing an opposing action against which said first and second ramps slide one relative to the other along an axis corresponding substantially to the axis of said ski when subjected to a vertical force, and release means located between said resilient means and said retaining means for disengaging said resilient means from said retaining means and from the boot extremity associated with said retaining means when said second ramp has slid with respect to said first ramp a distance less than the maximum travel of said ramps.

Claim 5

Dependent Claim 74 words

A device as defined in claim 2, wherein said retaining means consist of two levers articulated relative to said second holding means, each lever including at one end, a ramp cooperating with an associated boot extremity, at the other end, projections; said release means is constituted by an arm articulated at one end of a rod actuated by said resilient means, said arm co-operating in a releasable manner with said projections of said levers.

Claim 6

Dependent Claim 81 words

A device as defined in claim 3, wherein each of said levers is elbowed and rotatably movable about an axis which is fixed with respect to said second holding means and which is perpendicular to the plane of the ski; said arm is rotatably movable, at an intermediate point thereof, about an axis situated at said one end of said rod; said arm is further pivotable about one of its extremities resting against said projections when said boot is laterally urged.
