Abstract
Abstract A safety release ski binding mounted in association with a sole plate construction which is pivotally secured to the upper surface of a ski for movement about a vertical axis. The locking structure for holding the sole plate construction in alignment with the longitudinal axis of the ski also effects a holding of the jaw plate and associated front jaw in a fixed position to effectively hold the ski boot in engagement with the bindings associated with the sole plate construction. The sole plate, while being pivotally secured to the ski, remains with the ski even after a release of the ski boot from engagement therewith. Upon the occurrence of a sufficient force causing the sole plate to be pivoted beyond a predefined limit, the locking structure associated with the jaw plate is released so that the front jaw is freely movable away from the ski boot to permit a release of the ski boot from engagement therewith. Thereafter, the sole plate is returned to a position axially aligned with the longitudinal axis of the ski and the front jaw returned to the position of use.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
247 words
In a safety ski binding including a pivotally supported sole plate provided adjacent a front end thereof with a jaw plate having a holding jaw pivotally supported for movement about an axis which is perpendicular with respect to an upper surface of a ski, said sole plate being maintained in a centered position by means of a locking mechanism which is released upon exceeding a predetermined torque, the improvement comprising a mounting plate fixedly secured to said ski, said holding jaw having extension means thereon, slide piece means secured to said extension means and having laterally spaced extension members thereon, guide means on said mounting plate, laterally spaced sliding members slidingly supported on said guide means for movement longitdinally of said ski, said laterally spaced extension members slidingly engaging said sliding members to hold said holding jaw from turning about the pivot axis support therefor, said jaw plate including means for effecting a lengthwise adjustment of said jaw plate relative to said sole plate, and means on said jaw plate for maintaining said sliding members in said sliding engagement with said extension members, said sliding members sliding along said guide means as said jaw plate is positionally adjusted relative to said sole plate, a pivoting of said sole plate about said pivotal support therefor effecting a lateral sliding of said extension members relative to said sliding members until said extension members become disengaged from said sliding members at which time said holding jaw becomes free to pivot.
Claim 2
Dependent Claim
247 words
In a safety ski binding including a pivotally supported sole plate provided adjacent a front end thereof with a jaw plate having a holding jaw pivotally supported for movement about an axis which is perpendicular with respect to an upper surface of a ski, said sole plate being maintained in a centered position by means of a locking mechanism which is released upon exceeding a predetermined torque, the improvement comprising a mounting plate fixedly secured to said ski, said holding jaw having extension means thereon, slide piece means secured to said extension means and having laterally spaced extension members thereon, guide means on said mounting plate, laterally spaced sliding members slidingly supported on said guide means for movement longitdinally of said ski, said laterally spaced extension members slidingly engaging said sliding members to hold said holding jaw from turning about the pivot axis support therefor, said jaw plate including means for effecting a lengthwise adjustment of said jaw plate relative to said sole plate, and means on said jaw plate for maintaining said sliding members in said sliding engagement with said extension members, said sliding members sliding along said guide means as said jaw plate is positionally adjusted relative to said sole plate, a pivoting of said sole plate about said pivotal support therefor effecting a lateral sliding of said extension members relative to said sliding members until said extension members become disengaged from said sliding members at which time said holding jaw becomes free to pivot.
Claim 3
Dependent Claim
73 words
The safety ski binding according to claim 1, wherein said guide means includes a pair of frontwardly converging rails, each said rail slidably supporting a respective said sliding member and the degree of angular movement required of said sole plate before said extension members become disengaged from said sliding members and said holding jaw is rendered free to pivot being the same at all adjusted positions of said jaw plate and sliding members.
Claim 4
Dependent Claim
85 words
The safety ski binding according to claim 1, wherein said extension members are downward projections located rearwardly of said jaw plate and said means for maintaining said sliding members in sliding engagement with extension members is a rearwardly facing arcuate surface on said jaw plate, said sliding members each being positioned between and engaged with a respective said extension member and said arcuate surface on said jaw plate when the longitudinal axis of said sole plate is aligned with the longitudinal axis of said ski.
Claim 5
Dependent Claim
49 words
The safety ski binding according to claim 1, wherein said jaw plate has a recess on each lateral side of the center line therefor engageable with a respective one of said extension members for limiting the amount of pivotal movement of said holding jaw relative to said jaw plate.
Claim 6
Dependent Claim
35 words
The safety ski binding according to claim 1, wherein the part of the surfaces of said sliding members engaged by said extension members are forwardly sloped toward the two side edges of said mounting plate.
Claim 7
Dependent Claim
24 words
The safety ski binding according to claim 1, including a torsion spring having each leg connected to a respective one of said sliding members.
