Abstract
Abstract The toe iron comprises two levers, which are pivoted on vertical axes to a toe iron member which is secured to the skis. The levers are urged to a normal position by a spring and carry respective soleholders at their free ends. The levers consist of bell-crank levers and the second arm of each lever carries a bearing member. The bearing members are in contact with respective guideways of a yoke, which under the action of a spring acts on the bearing member and normally holds the levers in engagement with a stop that is fixed to the ski.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
185 words
A toe iron for safety ski bindings, the toe iron comprising: a toe iron member adapted to be secured to a ski and having a center line which lies substantially along the longitudinal center line of an associated ski; first and second levers pivotably mounted at one end on respective vertical axes opposite from one another on respective sides of the center line of the toe iron member; first and second soleholders mounted at the respective free ends of said first and second levers; a bearing member on each of said first and second levers nearer to the center line of said toe iron member than said vertical axes; a yoke adapted to move relative to the associated ski having first and second guideways for bearing against respective ones of said bearing members; a stop adapted to be fixed relative to the associated ski for limiting the movement of said first and second levers to a predetermined normal position; and spring means for biasing said yoke against said bearing members to thereby urge said first and second levers to pivot into engagement with said stop.
Claim 2
Dependent Claim
185 words
A toe iron for safety ski bindings, the toe iron comprising: a toe iron member adapted to be secured to a ski and having a center line which lies substantially along the longitudinal center line of an associated ski; first and second levers pivotably mounted at one end on respective vertical axes opposite from one another on respective sides of the center line of the toe iron member; first and second soleholders mounted at the respective free ends of said first and second levers; a bearing member on each of said first and second levers nearer to the center line of said toe iron member than said vertical axes; a yoke adapted to move relative to the associated ski having first and second guideways for bearing against respective ones of said bearing members; a stop adapted to be fixed relative to the associated ski for limiting the movement of said first and second levers to a predetermined normal position; and spring means for biasing said yoke against said bearing members to thereby urge said first and second levers to pivot into engagement with said stop.
Claim 3
Dependent Claim
24 words
A toe iron as set forth in claim 1, characterized in that the bearing members consist of rollers, which are rotatable on vertical axes.
Claim 4
Dependent Claim
41 words
A toe iron as set forth in claim 1, characterized in that the stop which is adapted to be fixed relative to the associated ski consists of a central vertical pin, which at its top end carries a sole holding-down member.
Claim 5
Dependent Claim
21 words
A toe iron as set forth in claim 3, characterized in that the pin is rotatable and is non-circular in cross-section.
Claim 6
Dependent Claim
17 words
A toe iron as set forth in claim 4, characterized in that the pin is axially adjustable.
Claim 7
Dependent Claim
52 words
A toe iron as set forth in claim 3, wherein each lever has a hole through which a screw for fixing the toe iron can be passed during the mouting of the toe iron, and characterized in that the sole holding-down member in its normal position covers the holes in the levers.
Claim 8
Dependent Claim
36 words
A toe iron as set forth in claim 1, characterized in that each lever has a hole through which a screw for fixing the toe iron can be passed during the mounting of the toe iron.
Claim 9
Dependent Claim
30 words
A toe iron as set forth in claim 1, wherein said yoke is pivotably mounted about an axis substantially perpendicular to and through the center line of the toe member.
Claim 10
Dependent Claim
32 words
A toe iron as set forth in claim 8, wherein the axis about which said yoke pivots is a pivot pin which is movable along the center line of the toe member.
Claim 11
Dependent Claim
25 words
A toe iron as set forth in claim 9, wherein the pivot pin is fixed to a shaft which is biased by said spring means.
