Abstract
The invention relates to a jaw, in particular a front jaw for safety ski bindings including a support member having at least two bolts therein symmetrically arranged with respect to a longitudinal center plane of the jaw and oriented perpendicularly with respect to the upper side of the ski. About each bolt is pivotally supported a two-arm sole holder, one arm of which engages the sole of a ski shoe and the other arm of which extends laterally inwardly toward the longitudinal axis of the ski and engages a part which is movable in the longitudinal direction of the ski against the force of a spring. The spring is supported at its one end on the support member and at its other end on an abutment which can be adjusted by means of an adjusting screw.
Claims14
In a front jaw for a safety ski binding adapted to be mounted on a ski, said jaw including a support member having at least two bolts thereon which are symmetrically arranged with respect to a longitudinal vertical center plane of the jaw and which are substantially perpendicular to the upper side of the ski, each said bolt pivotally supporting a respective sole holder, each said sole holder having a first arm which can engage the sole of a ski shoe and a second arm which extends approximately transversely of the ski and engages a release part, said release part being supported for movement longitudinally of the ski and being biased by a spring, said spring having one end supported on said support member and its other end supported on an abutment which is adjustable longitudinally of the ski relative to said release part by means of an adjusting screw, said support member being supported for movement longitudinally of the ski, the improvement comprising a support part which is supported for movement longitudinally of the ski on a guide rail which is adapted to be secured to and extend longitudinally of the ski, said support part being located on a side of said sole holders nearest the tip of the ski and engaging at least one stop pin which is provided on said guide rail and limits movement of said support part toward the tip of the ski, said support part having two support arms which extend away from the tip of the ski substantially parallel to the upper side of the ski and symmetrically to the longitudinal vertical center plane of the ski, each said support arm having a free end which engages said second arm of a respective one of said sole holders.
In a front jaw for a safety ski binding adapted to be mounted on a ski, said front jaw having a pair of symmetrically arranged two-arm sole holders supported for pivotal movement about respective axles which are perpendicular to the upper side of the ski and are supported on a support member which is supported for movement longitudinally of the ski on a guide rail, said guide rail being adapted to be secured to the ski, each said sole holder having a first arm which can engage a ski shoe and a second arm which engages one side of a slide member which is supported for movement longitudinally of the ski and is biased by a helical spring, said slide member being secured to one end of a draw rod which is arranged coaxially within said spring, wherein said spring has one end supported on an upright wall segment of said support member and has its other end supported on an abutment which is positionally adjustable relative to said draw rod by means of an adjusting screw, the improvement comprising wherein said upright wall segment of said support member has two openings therethrough;
- wherein said jaw includes a support part which is fixed against movement relative to the ski in a direction toward the tip thereof, which is located on a side of said upright wall segment remote from said sole holders, and which has two projections thereon which each extend through a respective said opening in said upright wall segment;
- and wherein said second arm of each said sole holder is engaged on a side thereof remote from said slide member by the free end of a respective one of said projections provided on said support part.
A safety ski binding jaw which is adapted to be mounted on a ski, comprising:
- a guide arrangement which can be secured to the ski;
- a support member which is supported on said guide arrangement for movement longitudinally of the ski;
- two sole holders supported on said support member for pivotal movement about respective, spaced, generally vertical axes, each said sole holder having first and second arms, said first arms being adapted to engage a ski boot and said second arms extending inwardly toward each other in directions generally transverse to the ski;
- resilient means cooperable with said sole holders for yieldably urging pivotal movement of each said sole holder in a first direction corresponding to movement of said second arm thereof in a direction toward the tip of the ski;
- and means on said support member for limiting pivotal movement of said sole holders in said first direction;
- said guide arrangement including a projection which engages said second arm of at least one said sole holder at a location thereon spaced from said pivot axis thereof.
