Abstract
Abstract A ski binding includes a soleplate, integral with a boot sole or adapted to carry a boot, to which a plate is hinged at one end about a transverse axis, this plate having an opening with a bevelled edge which passes about and comes to jam under the head of a pin fixed perpendicular to the ski. A spring urged locking member acts on the other end of the soleplate to releasably hold said other end against pivoting about said transverse axis or about said pin, and to releasably jam said opening under the head of the pin. A fixture can be provided for locking said plate on the ski whereby, when said locking member is disengaged, the soleplate is freed for pivoting about the transverse axis e.g. during ski touring.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
228 words
A ski binding, comprising; an elongate soleplate extending from a first end to a second end; an intermediate plate hingedly connected to the soleplate adjacent said first end about a transverse axis and having means defining an opening in said intermediate plate, said intermediate plate having a free end and an upper face; a pin attachable perpendicular to a ski, said pin having an enlarged head which can pass through said opening in the intermediate plate; means defining cooperating relatively inclined surfaces on the underside of said head of the pin and on said upper face of said intermediate plate in a part of said opening adjacent said free end; and spring operated means for releasably locking said second end of the soleplate to the ski subject to release of the soleplate by pivoting about said transverse axis and about said perpendicular pin, said spring operated means being attachable to the ski at a distance from said pin; whereby in use said spring operated means urges said sole- plate and said intermediate plate in a direction towards said pin to inter- engage said cooperating surfaces and thereby releasably to lock said sole- plate to the ski, subject to movement of said first end of the sole- plate relative to the ski to free said soleplate by coaction of said cooperating surfaces against the action of said spring-operated means.
Claim 2
Dependent Claim
228 words
A ski binding, comprising; an elongate soleplate extending from a first end to a second end; an intermediate plate hingedly connected to the soleplate adjacent said first end about a transverse axis and having means defining an opening in said intermediate plate, said intermediate plate having a free end and an upper face; a pin attachable perpendicular to a ski, said pin having an enlarged head which can pass through said opening in the intermediate plate; means defining cooperating relatively inclined surfaces on the underside of said head of the pin and on said upper face of said intermediate plate in a part of said opening adjacent said free end; and spring operated means for releasably locking said second end of the soleplate to the ski subject to release of the soleplate by pivoting about said transverse axis and about said perpendicular pin, said spring operated means being attachable to the ski at a distance from said pin; whereby in use said spring operated means urges said sole- plate and said intermediate plate in a direction towards said pin to inter- engage said cooperating surfaces and thereby releasably to lock said sole- plate to the ski, subject to movement of said first end of the sole- plate relative to the ski to free said soleplate by coaction of said cooperating surfaces against the action of said spring-operated means.
Claim 3
Dependent Claim
19 words
A ski binding according to claim 1, in which said soleplate is incorporated in a sole of a boot.
Claim 4
Dependent Claim
25 words
A ski binding according to claim 2, in which said soleplate comprises a generally flat plate attachable to a lower surface portion of said sole.
Claim 5
Dependent Claim
39 words
A ski binding according to claim 2, in which said boot sole includes means defining a recess for receiving therein said intermediate plate with said upper surface uppermost, and means for releasably holding the intermediate plate in said recess.
Claim 6
Dependent Claim
93 words
A ski binding according to claim 1, in which said first end of the soleplate is adapted to support the toe end of a boot and said second end is adapted to support the heel end of a boot, said spring-operated locking means comprising manually operable means for placing it in an inoperative position allowing free movement of said second end of the soleplate, the binding further comprising manually operable means for locking said soleplate and intermediate plate against pivoting about said pin while allowing pivoting of the soleplate about said transverse axis.
Claim 7
Dependent Claim
71 words
A ski binding according to claim 5, wherein said manually-operable locking means comprise a base plate adapted to be secured on the ski, a hook member slidably mounted on the base plate for movement along the axial direction of the ski, said hook member being adapted in one axial position to at least indirectly engage with and immobilize said intermediate plate, and screw means for holding said hook member in position.
Claim 8
Dependent Claim
40 words
A ski binding according to claim 1, in which said opening in the intermediate plate has an end portion which is V-shaped in plan view, and the means defining it comprises one of the means defining co-operative relatively inclined surfaces.
Claim 9
Dependent Claim
19 words
A ski binding according to claim 1, in which said soleplate is integral with the sole of a boot.
Claim 10
Dependent Claim
29 words
A ski binding according to claim 1 in which said spring-operated means includes manually operable means for unlocking the second end of the soleplate from the ski at will.
