Abstract
Abstract Quick-release heel hold-down device for ski binding, comprising a heel retaining jaw pivotally mounted on a fixed base member and responsive to the force of a spring constantly urging said jaw upwards to its release position. The resilient return means comprise a spring-loaded piston adapted to hold said jaw in its lower or operative position, and a pivoting member engaging on the one hand said pivoting jaw and on the other hand said piston of said resilient return means. Said pivoting member comprises a control edge in bearing engagement with the operative face of said spring-loaded piston of said resilient return means, said last-mentioned means acting through said control edge for constantly urging said pivoting member in the direction of rotation corresponding to the closing of said jaw. Said pivoting member has two end stable positions corresponding the one to the jaw opening position and the other to the jaw closing position, and said jaw comprises a control lug co-acting with said pivoting member in order to produce a selflocking action against the pressure force developed by said resilient return means in the end position corresponding to the open jaw position.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
217 words
A heel hold-down device for a ski binding comprising a base member adapted to be fixed on a ski, a heel retaining jaw having a contacting portion adapted to bear against the heel and pivotally mounted on said base member and rotatable about a first axis between an operative position wherein the heel is held down on said ski and a release position, a pivoting member mounted on said base member and adapted to pivot about a second axis substantially parallel to and spaced apart from said first axis, said pivoting member having a control edge, a resilient return means affixed to said base member and comprising a piston spring loaded toward and bearing against said pivoting member whereby said jaw is resiliently held in said operative position, a lug on said jaw bearing against said pivoting member at a bearing portion, said lug and said contacting portion being on opposite sides of said first axis and said control edge and said bearing portion being on opposite sides of said second axis, said pivoting member having a first and a second end stable position, said pivoting member being in said first position when said jaw is in said release position and said pivoting member being in said second position when said jaw is in said operative position.
Claim 2
Dependent Claim
217 words
A heel hold-down device for a ski binding comprising a base member adapted to be fixed on a ski, a heel retaining jaw having a contacting portion adapted to bear against the heel and pivotally mounted on said base member and rotatable about a first axis between an operative position wherein the heel is held down on said ski and a release position, a pivoting member mounted on said base member and adapted to pivot about a second axis substantially parallel to and spaced apart from said first axis, said pivoting member having a control edge, a resilient return means affixed to said base member and comprising a piston spring loaded toward and bearing against said pivoting member whereby said jaw is resiliently held in said operative position, a lug on said jaw bearing against said pivoting member at a bearing portion, said lug and said contacting portion being on opposite sides of said first axis and said control edge and said bearing portion being on opposite sides of said second axis, said pivoting member having a first and a second end stable position, said pivoting member being in said first position when said jaw is in said release position and said pivoting member being in said second position when said jaw is in said operative position.
Claim 3
Dependent Claim
65 words
A device according to claim 1 wherein said control edge is disposed between a first control surface and a second control surface formed on said pivoting member, said first surface stably bearing against said piston when said jaw is in said release position, said lug having a bearing contour adapted to stably bear against said bearing portion when said jaw is in said release position.
Claim 4
Dependent Claim
38 words
A device according to claim 2 wherein said second surface stably bears against said piston whEn said jaw is in said operative position, said lug stably bearing against said bearing portion when said jaw is in operative position.
Claim 5
Dependent Claim
62 words
A device according to claim 3 wherein said pivoting member has a substantially prismatic configuration with a cross-sectional contour corresponding substantially to an irregular trapezium having a minor base and a first non-parallel side and a second non-parallel side, said minor base constituting said second surface, said first side constituting said bearing portion and said second side consituting said first control surface.
Claim 6
Dependent Claim
59 words
A device according to claim 1 comprising a manual release lever pivotally mounted for rotation about said second axis, said lever adapted to pivot between an upper position corresponding to said release position and a lower position corresponding to said operative position, said lever being rotatably coupled to said pivoting member at least while pivoting toward said upper position.
Claim 7
Dependent Claim
50 words
A device according to claim 5 wherein said lever carries a bolt substantially parallel to said second axis, an arcuate aperture in said base member substantially concentric to said second axis, said bolt in said aperture and adapted to engage in said pivoting member while pivoting towards said upper position.
Claim 8
Dependent Claim
63 words
A device according to claim 5 wherein said lever comprises two substantially parallel spaced apart side arms extending outwardly from said base member, the outer ends of said arms being connected, the inner ends of said arms being connected to said pivoting member by at least one bolt extending through said pivoting member and adapted to travel in apertures in said base member.
Claim 9
Dependent Claim
17 words
A device according to claim 3 wherein said second control surface also acts as said bearing portion.
Claim 10
Dependent Claim
18 words
A device according to claim 1 wherein said piston is reciprocable toward and away from said pivoting member.
Claim 11
Dependent Claim
23 words
A device according to claim 1 wherein there is provided a spring bearing against said jaw and urging it towards said release position.
