Abstract
Abstract A baseplate carries a vertical pivot pin, on which a pivoted member is rotatably mounted which carries a soleholder, which is pivoted to the pivoted member on an axis which is parallel to the pivot pin on the baseplate. The soleholder is normally held against rotation by a detent device, which comprises a first member that is movable relative to a second member of the detent device to release the latter. The first member of the detent device is under the influence of the pivoted member in such a manner that the soleholder will be released when said member has performed a predetermined pivotal movement from its normal position.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
136 words
A toe iron for safety ski bindings comprising a baseplate, a vertical pivot pin secured to said baseplate, a spring carried by said vertical pivot pin, a swivel member rotatably mounted on said vertical pivot pin, a soleholder member rotatably mounted to said swivel member around an axis lying parallel to said vertical pivot pin, said soleholder member being normally held against rotation relative to said swivel member by an antirotation lock, said antirotation lock comprising a locking pin which extends in locked position through a horizontal division between said swivel member and said soleholder member, said soleholder member being unlocked from the locking pin by swinging the swivel member through a predetermined angle out of a central position by relative displacement of the swivel member in opposition to the force of said pivot pin spring.
Claim 2
Dependent Claim
136 words
A toe iron for safety ski bindings comprising a baseplate, a vertical pivot pin secured to said baseplate, a spring carried by said vertical pivot pin, a swivel member rotatably mounted on said vertical pivot pin, a soleholder member rotatably mounted to said swivel member around an axis lying parallel to said vertical pivot pin, said soleholder member being normally held against rotation relative to said swivel member by an antirotation lock, said antirotation lock comprising a locking pin which extends in locked position through a horizontal division between said swivel member and said soleholder member, said soleholder member being unlocked from the locking pin by swinging the swivel member through a predetermined angle out of a central position by relative displacement of the swivel member in opposition to the force of said pivot pin spring.
