Abstract
Abstract A pivoted member carries at least one soleholder and is mounted on a vertical carrying pin that is rigid with a base plate. The pivoted member is movable from its normal position against the force of at least one spring. At least one vertical and preferably flat surface is formed on that half of the carrying pin which is adjacent to the soleholder. A mating surface of the pivoted member is associated with each of said vertical surfaces and engages the same when the pivoted member is in its normal position. The mating surface or surfaces is a portion or are portions of the wall of the bearing of the pivoted member. Said bearing is clear of that half of the carrying pin which is remote from the soleholder when the pivoted member is in its normal position.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
210 words
A toe iron for safety ski bindings, which toe iron comprises a pivoted member, a base plate, a vertical carrying pin rigid with said base plate, at least one soleholder carried by said pivoted member, and at least one spring in cooperating relationship with said pivoted member, the pivoted member being movable from its normal position against the force of said spring, said carrying pin having at least one vertical surface formed on a half of the carrying pin adjacent to the soleholder, said pivoted member having a vertical bore forming a bearing surface, a portion of said bearing surface comprising a mating surface, said mating surface engaging said vertical surface of said carrying pin when the pivoted member is in its normal position, said bearing surface being free from engagement with tHe half of the carrying pin which faces away from the soleholder when the pivoted member is in its normal position, and the radius of curvature of said mating surface being less than the radius of curvature of said vertical surface of said carrying pin such that said pivoted member and said soleholder are moved rearward during the outward pivotal movement of said pivoted member and such that said soleholder prevents the forward movement of the ski boot.
Claim 2
Dependent Claim
210 words
A toe iron for safety ski bindings, which toe iron comprises a pivoted member, a base plate, a vertical carrying pin rigid with said base plate, at least one soleholder carried by said pivoted member, and at least one spring in cooperating relationship with said pivoted member, the pivoted member being movable from its normal position against the force of said spring, said carrying pin having at least one vertical surface formed on a half of the carrying pin adjacent to the soleholder, said pivoted member having a vertical bore forming a bearing surface, a portion of said bearing surface comprising a mating surface, said mating surface engaging said vertical surface of said carrying pin when the pivoted member is in its normal position, said bearing surface being free from engagement with tHe half of the carrying pin which faces away from the soleholder when the pivoted member is in its normal position, and the radius of curvature of said mating surface being less than the radius of curvature of said vertical surface of said carrying pin such that said pivoted member and said soleholder are moved rearward during the outward pivotal movement of said pivoted member and such that said soleholder prevents the forward movement of the ski boot.
Claim 3
Dependent Claim
210 words
A toe iron for safety ski bindings, which toe iron comprises a pivoted member, a base plate, a vertical carrying pin rigid with said base plate, at least one soleholder carried by said pivoted member, and at least one spring in cooperating relationship with said pivoted member, the pivoted member being movable from its normal position against the force of said spring, said carrying pin having at least one vertical surface formed on a half of the carrying pin adjacent to the soleholder, said pivoted member having a vertical bore forming a bearing surface, a portion of said bearing surface comprising a mating surface, said mating surface engaging said vertical surface of said carrying pin when the pivoted member is in its normal position, said bearing surface being free from engagement with tHe half of the carrying pin which faces away from the soleholder when the pivoted member is in its normal position, and the radius of curvature of said mating surface being less than the radius of curvature of said vertical surface of said carrying pin such that said pivoted member and said soleholder are moved rearward during the outward pivotal movement of said pivoted member and such that said soleholder prevents the forward movement of the ski boot.
Claim 4
Dependent Claim
210 words
A toe iron for safety ski bindings, which toe iron comprises a pivoted member, a base plate, a vertical carrying pin rigid with said base plate, at least one soleholder carried by said pivoted member, and at least one spring in cooperating relationship with said pivoted member, the pivoted member being movable from its normal position against the force of said spring, said carrying pin having at least one vertical surface formed on a half of the carrying pin adjacent to the soleholder, said pivoted member having a vertical bore forming a bearing surface, a portion of said bearing surface comprising a mating surface, said mating surface engaging said vertical surface of said carrying pin when the pivoted member is in its normal position, said bearing surface being free from engagement with tHe half of the carrying pin which faces away from the soleholder when the pivoted member is in its normal position, and the radius of curvature of said mating surface being less than the radius of curvature of said vertical surface of said carrying pin such that said pivoted member and said soleholder are moved rearward during the outward pivotal movement of said pivoted member and such that said soleholder prevents the forward movement of the ski boot.
Claim 5
Dependent Claim
27 words
A toe iron according to claim 1, wherein said at least one vertical surface is flat and extends tranversely to the longitudinal direction of the toe iron.
Claim 6
Dependent Claim
40 words
A toe iron according to claim 1, wherein said at least one vertical surface comprises two flat vertical surfaces which converge toward the soleholder and which define a vertex disposed on a central vertical longitudinal plane of the toe iron.
Claim 7
Dependent Claim
25 words
A toe iron according to claim 1 wherein said mating surface of said pivoted member has a recess which is defined by vertical edge lands.
Claim 8
Dependent Claim
102 words
A toe iron according to claim 1 wherein said pivoted member defines a horizontal recess, said spring being a helical compression spring mounted in said horizontal recess with one end of the spring bearing on the pivoted member, a piston in cooperating relationship with the spring, a second end of the spring acting by means of said piston on the carrying pin, that half of the carrying pin which is remote from the soleholder being symmetrical relative to the other half, and the piston defining a mating surface which engages the carrying pin when the pivoted member is in its normal position.
Claim 9
Dependent Claim
133 words
A toe iron according to claim 1 wherein said pivoted member has a second vertical bore and wherein said toe iron includes a locking and guiding track provided in said baseplate and a detent and returning device including a detent member and said at least one spring which consists of a helical compression spring mounted in said second vertical bore of said pivoted member and with its upper end bearing on said pivoted member and its lower end acting on said detent member to urge said detent member against said locking and guiding track, said locking and guiding track extending upwardly symmetrically to the central longitudinal axis of said toe iron and extending toward the rear end of the ski along the path followed by said pivoted member during its outward pivotal movement.
Claim 10
Dependent Claim
35 words
A toe iron according to claim 1 wherein said at least one soleholder is mounted on said pivoted member so that it is capable of making a limited vertical pivotal movement about a vertical axis.
