Abstract
Abstract A soleholder carrier is mounted on a toe iron member that is fixed to the ski. The soleholder carrier is mounted on said toe iron member for rotation about a vertical pivot pin against the force of a helical compression spring and forms a stop, which is engageable by the toe portion of the boot and is so shaped that the boot will not be moved in the longitudinal direction of the ski, or will be moved only to a negligible extent in said direction, before the toe iron has reached its released position. The helicaL compression spring is mounted in a horizontal recess of the soleholder carrier and bears at one end on the carrier by means of an adjustable stop. The spring acts at the other end by means of a piston on a flat formed on the pivot pin. The piston is formed with a vertical recess at its end facing the pivot pin. The width of said vertical recess is smaller than the width of the flat formed on the pivot pin.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
101 words
A toe iron for safety ski bindings comprising pivot axis means defining a pivot axis fixed to the ski, a soleholder carrier mounted on said pivot axis means and disposed to pivot about said pivot axis, a soleholder member pivotally mounted on said soleholder carrier, said pivot axis means defining a flat surface, a piston engaging the flat surface of pivot axis means, a spring mounted in said soleholder carrier biasing said piston toward said flat surface, with the surface of said piston engaging said flat surface defining a recess having a width smaller than the width of said flat surface.
Claim 2
Dependent Claim
101 words
A toe iron for safety ski bindings comprising pivot axis means defining a pivot axis fixed to the ski, a soleholder carrier mounted on said pivot axis means and disposed to pivot about said pivot axis, a soleholder member pivotally mounted on said soleholder carrier, said pivot axis means defining a flat surface, a piston engaging the flat surface of pivot axis means, a spring mounted in said soleholder carrier biasing said piston toward said flat surface, with the surface of said piston engaging said flat surface defining a recess having a width smaller than the width of said flat surface.
Claim 3
Dependent Claim
38 words
A toe iron as set forth in claim 1 including a locking means restricting rotation of the soleholder member relative to the soleholder carrier and being releasable in response to a predetermined pivotal movement of the soleholder carrier.
Claim 4
Dependent Claim
40 words
A toe iron as set forth in claim 1, wherein said recess is rounded with its axis of curvature parallel to said pivot axis and its radius of curvature equal to the radius of curvature of the pivot axis means.
Claim 5
Dependent Claim
26 words
A toe iron as set forth in claim 3, wherein said recess has an axis of curvature lying in the plane of symmetry of said piston.
Claim 6
Dependent Claim
51 words
A toe iron as set forth in claim 1, wherein said spring is a helical compression spring and is received in a horizontal recess defined by said soleholder carrier and a cap is threadedly engaged with said soleholder carrier, said cap serving as an adjustable abutment for said helical compression spring.
Claim 7
Dependent Claim
27 words
A toe iron as set forth in claim 5, wherein a rod is connected to said piston and extends outwardly through an axial bore in said cap.
Claim 8
Dependent Claim
83 words
A toe iron for safety bindings comprising a pivot axis means, defining a pivot axis fixed to the ski, a soleholder carrier mounted on said pivot axis means and disposed to pivot about said pivot axis, a soleholder member pivotally mounted on said soleholder carrier, a spring-biased piston bearing against a flat surface of said pivot axis means, said piston being constructed to form forklike extensions, which extend past said pivot axis means to cooperate with mating portions defined by said soleholder member.
Claim 9
Dependent Claim
83 words
A toe iron for safety bindings comprising a pivot axis means, defining a pivot axis fixed to the ski, a soleholder carrier mounted on said pivot axis means and disposed to pivot about said pivot axis, a soleholder member pivotally mounted on said soleholder carrier, a spring-biased piston bearing against a flat surface of said pivot axis means, said piston being constructed to form forklike extensions, which extend past said pivot axis means to cooperate with mating portions defined by said soleholder member.
