Abstract
Abstract The invention relates to a front piece for safety ski-bindings. The front piece comprises a supporting member which can be pivoted sideways. Linked to the support member are side clamps for engaging the toe of a ski boot in order to hold the ski boot in the front piece of the safety ski-binding. The side clamps are releasable when a predetermined force is applied to the side of the ski binding. The binding of the present invention will automatically reset after the side clamp is released and the boot is free from the binding. An advantage of the mechanism of the present invention is that internal friction is minimized during the release/reset operation. This is achieved in part by the side clamps being designed such that they are extended beyond their respective points where they are pivotally attached to the supporting member.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
242 words
A front piece for a safety ski binding, said front piece comprising: base means mountable between the sides of a ski; supporting means mounted for sideways movement on said base means, said supporting means including: side clamp means for engaging the sides of a ski boot, said side clamp means having a holding condition for holding a ski boot in the front piece and an open condition for releasing a ski boot; coupling means interconnecting said side clamp means; mounting means for pivotally attaching said side clamp means to said coupling means; and, extension means attached to said mounting means beyond the point of pivotal attachment of said side clamp means to said coupling means for extending the effective length of said side clamp means; releasing means connected to said extension means for controlling the condition of said side clamp means, said releasing means having a locking condition for restraining said extension means to lock said clamp means in the holding condition and an unlocking condition for enabling said clamp to assume the open condition; and, locking means for releasably locking said releasing means in the locking condition, said locking means moving to a releasing position in response to the pivoting of said support means beyond a predetermined amount in response to forces applied to said clamp means to unlock said releasing means to the unlocking condition to release said extension means and enable said clamp means to assume the open condition.
Claim 2
Dependent Claim
242 words
A front piece for a safety ski binding, said front piece comprising: base means mountable between the sides of a ski; supporting means mounted for sideways movement on said base means, said supporting means including: side clamp means for engaging the sides of a ski boot, said side clamp means having a holding condition for holding a ski boot in the front piece and an open condition for releasing a ski boot; coupling means interconnecting said side clamp means; mounting means for pivotally attaching said side clamp means to said coupling means; and, extension means attached to said mounting means beyond the point of pivotal attachment of said side clamp means to said coupling means for extending the effective length of said side clamp means; releasing means connected to said extension means for controlling the condition of said side clamp means, said releasing means having a locking condition for restraining said extension means to lock said clamp means in the holding condition and an unlocking condition for enabling said clamp to assume the open condition; and, locking means for releasably locking said releasing means in the locking condition, said locking means moving to a releasing position in response to the pivoting of said support means beyond a predetermined amount in response to forces applied to said clamp means to unlock said releasing means to the unlocking condition to release said extension means and enable said clamp means to assume the open condition.
Claim 3
Dependent Claim
60 words
The invention according to claim 1 wherein said locking means comprises locking lever means pivotally mounted on said supporting means, and wherein the invention further includes control means mounted on said base means for pivoting said locking lever means to engage said releasing means to the releasing position in response to movement of said support means by said predetermined amount.
Claim 4
Dependent Claim
63 words
The invention according to claim 2 wherein said control means comprises a control member mounted in the central portion of said front piece, and said locking lever means comprises a pair of diverging curved arms located respectively on opposite sides of said control means for engaging said control means according to the one of said side clamp means to which force is applied.
Claim 5
Dependent Claim
15 words
The invention according to claim 3 wherein said control means comprises a spring biased bolt.
Claim 6
Dependent Claim
20 words
The invention according to claim 1, said supporting means further comprising connecting lever means for connecting said extension means together.
Claim 7
Dependent Claim
72 words
The invention according to claim 5 wherein said connecting lever means comprise connecting levers attached to the respective extension means, and said front piece further comprising connecting pin means for pivotally interconnecting said connecting levers, said releasing means including detent means wherein said locking means acts in cooperation with said detent means to restrain said connecting pin means in said detent means to releasably lock said clamp means in the holding condition.
Claim 8
Dependent Claim
59 words
The invention according to claim 1 wherein said releasing means includes detent means with movable detent indentation means for cooperating with said locking means, said movable detent indentation means comprising a pair of levers crossing each other, said crossing levers being mounted on axles attached to said base means, and spring means biasing said crossing levers at their intersection.
Claim 9
Dependent Claim
307 words
A front piece for a safety ski binding, said front piece comprising: base means mountable between the sides of a ski; supporting means mounted for sideways movement on said base means, said supporting means including: side clamp means for engaging the sides of a ski boot, said side clamp means having a holding condition for holding a ski boot in the front piece and an open condition for releasing a ski boot; coupling means interconnecting said side clamp means; mounting means for pivotally attaching said side clamp means to said coupling means; and, extension means attached to said mounting means beyond the point of pivotal attachment of said side clamp means to said coupling means for extending the effective length of said side clamp means; releasing means connected to said extension means for controlling the condition of said side clamp means, said releasing means having a locking condition for restraining said extension means to lock said clamp means in the holding condition and an unlocking condition for enabling said clamp to assume the open condition; and, locking means for releasably locking said releasing means in the locking condition, said locking means moving to a releasing position in response to the pivoting of said support means beyond a predetermined amount in response to forces applied to said clamp means to unlock said releasing means to the unlocking condition to release said extension means and enable said clamp means to assume the open condition; and, connecting lever means comprising connecting levers attached to the respective extension means, and said front piece further comprising connecting pin means for pivotally interconnecting said connecting levers, said releasing means including detent means wherein said locking means acts in cooperation with said detent means to restrain said connecting pin means in said detent means to releasably lock said clamp means in the holding condition.
