Abstract
Abstract A ski binding part having a pair of symmetrically arranged sole holders which are pivotably supported on a base part. The sole holders comprise a pair of two arm levers pivotally supported on the base part. One arm of each of the two arm levers engages the sole of the boot and the other arm engages through a structural part a spring so that the two arm levers are resiliently urged into engagement with the sole of the boot.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
131 words
A ski binding part, comprising: a base member; a traction member mounted for reciprocal movement on said base member and having means defining at least one groove therein; a pair of two arm levers pivotally mounted on said base member, one arm of each of said levers being movable about a pivot axis therefor between a boot engaging and a boot releasing position, the other arm of each of said levers including toothed means continuously engaging said groove means for effecting a simultaneous movement of both of said levers about said pivot axes therefor to said boot releasing position whenever a sufficient force is applied to one of said levers and a corresponding reciprocal movement of said traction member; and resilient means for biasing said levers into said boot engaging position.
Claim 2
Dependent Claim
131 words
A ski binding part, comprising: a base member; a traction member mounted for reciprocal movement on said base member and having means defining at least one groove therein; a pair of two arm levers pivotally mounted on said base member, one arm of each of said levers being movable about a pivot axis therefor between a boot engaging and a boot releasing position, the other arm of each of said levers including toothed means continuously engaging said groove means for effecting a simultaneous movement of both of said levers about said pivot axes therefor to said boot releasing position whenever a sufficient force is applied to one of said levers and a corresponding reciprocal movement of said traction member; and resilient means for biasing said levers into said boot engaging position.
Claim 3
Dependent Claim
49 words
A ski binding part according to claim 1, wherein said traction member has a plurality of grooves thereon; and wherein said toothed means comprises a toothed segment which is concentrical about said pivot axes, said toothed segment rolling during a pivotal movement of said levers along in said grooves.
Claim 4
Dependent Claim
98 words
A ski binding part according to claim 1, wherein said one arm on each of said levers abut laterally on the boot sole; and wherein a further sole holder is provided, said further sole holder being pivotable about an axis arranged transversely to the longitudinal axis of said ski and being adapted to grip over the top of the boot sole, said further sole holder having toothed means thereon engaging said groove means and effecting a simultaneous movement of said levers and said traction member in response to a sufficient force being applied to said further sole holder.
Claim 5
Dependent Claim
81 words
A ski binding part according to claim 1, wherein said reciprocal traction member extends through a bore in said base member extending parallel to the longitudinal axis of said ski and has a thread at an end remote from said groove means, a nut threadedly engaged with said thread; and wherein said resilient means comprises a spring sleevably mounted over said reciprocal traction member and supported at one end on said base member and at the other end on said nut.
Claim 6
Dependent Claim
43 words
A ski binding part according to claim 1, wherein the pivot axes for said levers are inclined toward one another upwardly away from said ski and toward a plane parallel to the longitudinal axis of said ski and passing through the center thereof.
Claim 7
Dependent Claim
83 words
A ski binding part according to claim 1, wherein said base member further comprises a base plate and pivot means for pivotally supporting said base member, each of said levers being supported for movement with said base member about the pivot axis of said pivot means and releasable locking means for releasably locking said base member to said base plate to hold said base member in a central position wherein said levers are symmetrically arranged relative to the longitudinal axis of said ski.
Claim 8
Dependent Claim
55 words
A ski binding part according to claim 6, wherein said locking means is defined by a downwardly extending projection engaging a recess in said base plate, said projection being secured to said traction member and movable therewith whereby a reciprocal movement of said traction member will effect a movement of said projection from said recess.
Claim 9
Dependent Claim
25 words
A ski binding part according to claim 8, wherein said groove means comprises a plurality of annular grooves around the periphery of said traction member.
