Claims
- 1. A front jaw in safety ski bindings for holding a ski boot onto a ski, comprising:
- base means mounted on said ski and having a pair of horizontally spaced vertical posts fixedly secured thereto;
- a two-arm lever pivotally mounted on each of said vertical posts for movement between a ski boot engaging and a ski boot releasing position, each two-arm lever having a long arm adapted to engage said ski boot and a short arm, at least one of said short arms having cam means connected thereto and movable therewith, said cam means further including a single cam plate pivotally supported on said base means for movement about a pivot axis and having a contoured edge thereon, said cam plate being pivotally secured to both of said short arms through a pair of pivot axes which are both parallel to said plane defined by said vertical axes of said posts; and
- resilient locking means mounted on said base means and consisting of a single elongated spring and a single locking member, the longitudinal axis of said spring being immovably fixed to said base means and extending perpendicular to said pivot axis and to a plane defined by said vertical axes of said posts, said spring resiliently urging said locking member into engagement with said contoured edge of said cam plate, the spacing between said contoured edge and an abutment for said spring becoming smaller as at least one of said two-arm levers is swung from said ski boot engaging position toward said ski boot releasing position, said spring backed locking member resisting a lateral pivotal movement of said two-arm levers toward a ski boot releasing position.
- 2. A front jaw according to claim 1, wherein said pivot axis of said cam plate is horizontal;
- wherein said spring extends perpendicular to said horizontal pivot axis of said cam plate; and
- wherein said pivot axes connecting said short arms to said cam plate are horizontal.
- 3. A front jaw according to claim 2, wherein said cam plate is centrally disposed between said vertical posts.
- 4. A front jaw according to claim 2, wherein the forward edge of said cam plate has said contoured edge thereon.
- 5. A front jaw according to claim 2, wherein said pivotal connection of said short arms to said cam plate comprises a pair of pins extending outwardly from said cam plate parallel to said plane, each of said pins being received in a fork-shaped flange mounted on each of said short arms.
- 6. A front jaw according to claim 1, wherein said cam plate is a cylinder having a flat face thereon parallel to the axis thereof, said axis of said cylinder extending horizontally and parallel to the plane defined by said vertical posts;
- wherein said cylinder is pivotally secured to both of said short arms through a pair of horizontal pivot axes which are both parallel to said plane; and
- wherein said locking member is a piston resiliently urged into engagement with said flat face.
- 7. A front jaw according to claim 6, wherein said flat face is vertical;
- wherein the longitudinal axis of said spring is perpendicular to said flat face.
- 8. A front jaw according to claim 6, wherein said pivotal connection of said short arms to said cylinder comprises a pair of pins extending outwardly from said cylinder parallel to the plane of said flat face, each of said pins being received in a fork-shaped flange mounted on each of said short arms.
- 9. A front jaw according to claim 1, wherein said cam plate is pivotally supported on said base for movement about a vertical axis;
- wherein said longitudinal axis of said spring extends perpendicular to said vertical axis and to a plane defined by said vertical axes of said posts; and
- wherein said cam plate is pivotally secured to both of said short arms through a pair of vertical pivot axes which are both parallel to said plane defined by said vertical axes of said posts.
- 10. A front jaw according to claim 9, wherein the forward edge of said cam plate has said contoured edge thereon.
- 11. A front jaw according to claim 9, wherein said pivotal connection of said short arms to said cam plate comprises a pair of pins extending vertically from said cam plate parallel to said plane defined by said vertical axes of said posts, each of said pins being received in a slot in each of said short arms.
