Claim 1
Independent Claim
235 words
A safety ski binding for securing a ski boot to a ski having a median plane extending along the center of the ski and perpendicular to the ski, said binding comprising: a toe boot element on the toe of said ski boot; a heel boot element on the heel of said ski boot; a toe ski element secured to said ski at said median plane and lockingly engageable with said toe boot element, one of said toe elements comprising a pair of generally cylindrical and parallel pins flanking said median plane and the other of said toe elements being a profiled button lying in said plane and engageable between said pins; means coacting between said toe elements for resisting vertical release of the boot from the ski; a heel ski element secured to said ski at said median plane, and lockingly engageable with said heel boot element, one of said heel elements being a generally cylindrical body having an axis lying substantially perpendicular to said plane and being formed at said plane with a circumferential groove and the other heel element being a profiled button lying in said plane and engaging in said groove in force-transmitting relationship in said plane along said ski; and means for urging one of said ski elements along said plane toward the other ski element whereby a biasing force is applied through said boot elements to said other ski element.
Claim 2
Dependent Claim
235 words
A safety ski binding for securing a ski boot to a ski having a median plane extending along the center of the ski and perpendicular to the ski, said binding comprising: a toe boot element on the toe of said ski boot; a heel boot element on the heel of said ski boot; a toe ski element secured to said ski at said median plane and lockingly engageable with said toe boot element, one of said toe elements comprising a pair of generally cylindrical and parallel pins flanking said median plane and the other of said toe elements being a profiled button lying in said plane and engageable between said pins; means coacting between said toe elements for resisting vertical release of the boot from the ski; a heel ski element secured to said ski at said median plane, and lockingly engageable with said heel boot element, one of said heel elements being a generally cylindrical body having an axis lying substantially perpendicular to said plane and being formed at said plane with a circumferential groove and the other heel element being a profiled button lying in said plane and engaging in said groove in force-transmitting relationship in said plane along said ski; and means for urging one of said ski elements along said plane toward the other ski element whereby a biasing force is applied through said boot elements to said other ski element.
Claim 3
Dependent Claim
26 words
The ski binding defined in claim 1 wherein both of said buttons have heads formed as bodies of revolution with a common axis in said plane.
Claim 4
Dependent Claim
48 words
The ski binding defined in claim 2 wherein said means for urging includes an abutment fixed on said ski, a piston displaceable along said abutment in said plane toward the other ski element and carrying said one ski element, and a spring between said piston and said abutment.
Claim 5
Dependent Claim
17 words
The ski binding defined in claim 3 wherein said heel ski element is carried on said piston.
Claim 6
Dependent Claim
61 words
The ski binding defined in claim 4 wherein said one toe element is formed with a camming surface transverse to said plane and inclined upwardly from said ski toward the other toe element, whereby lifting of the toe of said boot forces said other toe element up against said camming surfaces and drives said boot back against said heel ski element.
Claim 7
Dependent Claim
39 words
The ski binding defined in claim 5, further comprising a fork pivotal about an axis perpendicular to said plane and carrying said toe ski element, and catch means for holding said fork in a position nonpivotal about its axis.
Claim 8
Dependent Claim
17 words
The ski binding defined in claim 6 wherein said toe ski element comprises said pair of pins.
Claim 9
Dependent Claim
32 words
The ski binding defined in claim 4, further comprising a sole plate carrying said heel and toe boot elements, and means for securing said plate to the underside of said ski boot.
Claim 10
Dependent Claim
39 words
The ski binding defined in claim 8 wherein said means for securing includes a flexible cable having both ends attached to said plate and a toggle catch engaging said cable intermediate said ends and lockingly engageable over said boot.
Claim 11
Dependent Claim
60 words
The ski binding defined in claim 4, further comprising means for displacing said toe ski element between a first position pressing against said to boot element and forcing said heel boot element against said heel ski element and a second position spaced from said toe boot element and for locking said toe ski element alternately in either of said positions.
