Safety ski binding

Claim 2

A safety ski binding, comprising: a base member having means defining a locking projection thereon; sole holder means pivotally supported to said base member for movement about a first pivot axis; support means pivotally supported to said base member for movement about a second pivot axis, said support means including guide means thereon and a movable locking part guided for movement by said guide means; a locking member pivotally supported on said sole holder means, said locking member having a recess therein receiving said locking projection when said sole holder means is in a position of use; resilient means mounted on and movable with said support means, said resilient means being positioned between and engaging said support means and said locking part to resiliently urge said locking part into engagement with said locking member so that said locking member is also urged by said resilient means into engagement with said locking projection, said locking projection being maintained in said recess by the force of said resilient means; and release lever means pivotally supported on said sole holder means for movement between first and second limits about a third pivot axis, said release lever means including securement means for securing said release lever means to said support means, whereby a pivoting movement of said release lever means about said third pivot axis will effect a pivoting movement of said support means about said second pivot axis to prevent said resilient means from resiliently urging said locking part into engagement with said locking member so that said sole holder is free to pivot about said first pivot axis.

Claim 3

A safety ski binding according to claim 1, wherein said locking member has a pair of spaced pockets thereon separate from said recess, said locking part being urged, when said sole holder means is in said position of use and said release lever means is at said first limit, into one of said pockets to urge said locking projection into said recess and into the other of said pockets when said release lever means is at said second limit.

Claim 4

A safety ski binding according to claim 1, wherein said first and second pivot axes are one and the same pivot axis.

Claim 5

A safety ski binding according to claim 1, wherein said release lever means is movable relative to said third pivot axis, said release lever means having at least one slotted guideway therein and a slide slidably received in said guideway, said third pivot axis being defined by at least one pin secured to said slide.

Claim 6

A safety ski binding according to claim 4, wherein said securement means includes an elongated slot in said sole holder means receiving a pin secured to said release lever means, said pin being connected to said support means.

Claim 7

A safety ski binding according to claim 5, wherein said elongated slot is arcuate and concentric about said second pivot axis.

Claim 8

A safety ski binding according to claim 4, wherein said release lever means includes a pair of arms straddling said sole holder means, each of said arms having one of said slotted guideways thereon, said third pivot axis being defined by a pair of axially aligned pins, each being secured to a slide in one of said guideways.

Claim 9

A safety ski binding according to claim 1, wherein said support means is generally U-shaped having a pair of parallel arms; wherein said guide means comprises an elongated slot in each of said parallel arms, said locking part being slidingly received in both of said slots.

Claim 10

A safety ski binding according to claim 8, wherein said resilient means is a spring extending between a bight portion of said U-shaped support means and said locking part.

Claim 11

A safety ski binding, comprising: a base member having means defining one of a locking projection and recess thereon; sole holder means pivotally supported to said base member for movement about a first pivot axis; support means pivotally supported to said base member for movement about a second pivot axis, said support means including a movable locking part thereon; a locking member pivotally supported on said sole holder means, said locking member having the other of said locking projections and said recess thereon and engaging said one of said locking projection and said recess when said sole holder means is in a position of use; resilient means mounted on and movable with said support means, said resilient means being positioned between and engaging said support means and said locking part to resiliently urge said locking part into engagement with said locking member so that said locking member is also urged by said resilient means into engagement with said one of said locking projection and said recess, one of said locking projection and said recess being maintained in engagement with said other of said locking projection and said recess by the force of said resilient means; and release lever means pivotally supported on said sole holder means for movement between first and second limits about a third pivot axis, said release lever means including securement means for securing said release lever means to said support means, whereby a pivoting movement of said release lever means about said third pivot axis will effect a pivoting movement of said support means about said second pivot axis to prevent said resilient means from resiliently urging said locking part into engagement with said locking member so that said sole holder is free to pivot about said first pivot axis.

Claim 12

A safety ski binding, comprising: a base member having means defining one of a locking projection and recess thereon; sole holder means pivotally supported to said base member for movement about a first pivot axis; support means pivotally supported to said base member for movement about a second pivot axis, said support means including a movable locking part thereon; a locking member pivotally supported on said sole holder means, said locking member having the other of said locking projections and said recess thereon and engaging said one of said locking projection and said recess when said sole holder means is in a position of use; resilient means mounted on and movable with said support means, said resilient means being positioned between and engaging said support means and said locking part to resiliently urge said locking part into engagement with said locking member so that said locking member is also urged by said resilient means into engagement with said one of said locking projection and said recess, one of said locking projection and said recess being maintained in engagement with said other of said locking projection and said recess by the force of said resilient means; and release lever means pivotally supported on said sole holder means for movement between first and second limits about a third pivot axis, said release lever means including securement means for securing said release lever means to said support means, whereby a pivoting movement of said release lever means about said third pivot axis will effect a pivoting movement of said support means about said second pivot axis to prevent said resilient means from resiliently urging said locking part into engagement with said locking member so that said sole holder is free to pivot about said first pivot axis.
