Abstract
Abstract A step-in safety heel ski binding wherein a heel-holding link is movable by the ski boot from a raised position to a lower position and is moved into engagement with parts fixed to the ski in a first intermediate position which is nearer to the lower position than a second intermediate position in which the link is released from such parts on forcible movement from lower position toward raised position. A spring is stressed during movement of the link from raised position to first intermediate position and biases the link from first intermediate position to lower position.

In a step-in safety heel ski binding, a combination comprising at least one part mounted on the ski; a linkage including supporting means arranged secured to the ski and a heel-holding member movably carried by said supporting means and being movable by a ski boot from a raised position through a first intermediate position, in which it is moved into engagement with said part, and to a lower position; and deformable biasing means for urging said heel-holding member to lower position when said member reaches the first intermediate position during movement from raised position, said biasing means offering to said heel-holding member a greater resistance during movement from lower position to a second intermediate position and a lesser resistance during movement from said second intermediate position to raiseD position, the distance between said first intermediate and lower positions being substantially less than the distance between said second intermediate and lower positions.
Claim 3
Dependent Claim
50 words
A combination as defined in claim 1, wherein said biasing means comprises spring means whose length varies in response to deformation thereof and wherein the distance between said raised and lower positions of said member exceeds the maximum change in length of said spring means by at least 50 percent.
Claim 4
Dependent Claim
19 words
A combination as defined in claim 2, wherein said distance is more than twice said maximum change in length.
Claim 5
Dependent Claim
51 words
A combination as defined in claim 1, wherein said heel-holding member comprises a heel-engaging portion which remains in engagement with the heel during movement of said member from lower to second member intermediate position and moves away from the heel during movement of said member from second intermediate to raised position.
Claim 6
Dependent Claim
53 words
A combination as defined in claim 1, further comprising means for stressing said biasing means during a portion of movement of said heel-holding member from raised to lower position, the distance covered by said member during said portion of its movement being less than half the distance between said raised and lower positions.
Claim 7
Dependent Claim
45 words
A combination as defined in claim 1, wherein said part mounted on the ski comprises further locking means against which said biasing means reacts in the lower position of said heel-holding member so that said biasing means opposes movement of said member from lower position.
Claim 8
Dependent Claim
19 words
A combination as defined in claim 1, further comprising means for regulating the initial stress of said biasing means.
Claim 9
Dependent Claim
72 words
A combination as defined in claim 1, wherein said part mounted on the ski comprises locking means having a first portion arranged to releasably hold said biasing means in stressed condition so that the biasing means opposes movement of said heel-holding member from lower position and a second portion which permits said first portion to release said biasing means on movement of said member from lower position to said second intermediate position.
Claim 10
Dependent Claim
36 words
A combination as defined in claim 8, wherein said locking means comprises a lever pivotally mounted on said supporting means and having first and second arms which are respectively provided with said first and second portions.
Claim 11
Dependent Claim
38 words
A combination as defined in claim 9, further comprising blocking means for holding said lever against pivotal movement in a direction to release said biasing means while said member remains at a level below said second intermediate position.
Claim 12
Dependent Claim
17 words
A combination as defined in claim 10, wherein said blocking means is provided on said heel-holding member.
Claim 13
Dependent Claim
133 words
A combination as defined in claim 1, wherein said linkage further comprises a link pivotable with reference to said heel-holding member and arranged to stress said biasing means during movement of said member from raised position to said first intermediate position thereof, said part mounted on the ski comprising locking means provided on said supporting means and operative to take up the stress of said biasing means in the first intermediate position of said member so that the biasing means thereupon urges said member toward lower position, and blocking means for holding said locking means in operative position during movement of said member from lower position to said second intermediate position against the opposition of said biasing means whereby said biasing means is thereupon free to propel the heel-holding member toward raised position.
Claim 14
Dependent Claim
129 words
A combination as defined in claim 1, wherein said linkage further comprises a link pivotally connected with said heel-holding member and cam means carried by said link and arranged to stress said biasing means during movement of said member from raised position to said first intermediate position, and further comprising a retainer movable with reference to said heel-holding member and interposed between said Cam means and said biasing means, said part mounted on the ski including locking means movably secured to said supporting means and arranged to engage said retainer on completed movement of said member from raised position to first intermediate position, and blocking means for holding said locking means in engagement with said retainer during movements of said member from lower position to said second intermediate position.
