Abstract
Abstract A safety ski binding in which a ball is mounted on the ski and engages the socket of ski boot engaging means. A detent recess is provided in the ball and receives a spring-backed holding device mounted in the ski boot engaging means. The ski boot engaging means is thereby normally held in a selected position as determined by said detent recess but same can move out of such normal position in any direction permitted by the ball-and-socket relationship upon application of sufficient force thereto.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
194 words
A safety ski binding, comprising: a ball head fixedly secured to a ski and having a detent recess therein located above a horizontal plane through the center thereof and to one side of a vertical plane through the center thereof; ski boot engaging means having means thereon to engage said ball head and support said ski boot engaging means for swivelable movement, said ski boot engaging means having elongated housing means defining an action line, the longitudinal axis of said action line intersecting said vertical plane at a point radially offset from the center point of said ball head; locking means on said elongated housing means adapted to move along said action line toward and away from said ball head, said locking means, when in a first position being partially received in said recess to lock said ski boot engaging means to said ball head and when in a second position permitting a swiveling movement of said ski boot engaging means relative to said ball head; and resilient means adapted to urge said locking means toward said ball head at all times to yieldably resist said swiveling movement of said ski boot engaging means.
Claim 2
Dependent Claim
194 words
A safety ski binding, comprising: a ball head fixedly secured to a ski and having a detent recess therein located above a horizontal plane through the center thereof and to one side of a vertical plane through the center thereof; ski boot engaging means having means thereon to engage said ball head and support said ski boot engaging means for swivelable movement, said ski boot engaging means having elongated housing means defining an action line, the longitudinal axis of said action line intersecting said vertical plane at a point radially offset from the center point of said ball head; locking means on said elongated housing means adapted to move along said action line toward and away from said ball head, said locking means, when in a first position being partially received in said recess to lock said ski boot engaging means to said ball head and when in a second position permitting a swiveling movement of said ski boot engaging means relative to said ball head; and resilient means adapted to urge said locking means toward said ball head at all times to yieldably resist said swiveling movement of said ski boot engaging means.
Claim 3
Dependent Claim
109 words
A safety ski binding according to claim 1, wherein said elongated housing means has an opening therethrough, the longitudinal axis of which defines said action line which intersects said vertical plane at a point offset from the center point of said ball head; including adjustable stop means at one end of said opening adapted for adjustable movement longitudinally of said opening; and wherein said resilient means comprises a spring positioned within said opening in said elongated housing between said aDjustable stop means and said locking means, an adjustment of said adjustable stop means longitudinally of said opening regulating the engagement force between said locking means and said ball head.
Claim 4
Dependent Claim
23 words
A safety ski binding according to claim 1, wherein said locking means is a ball and said detent recess has a conical shape.
Claim 5
Dependent Claim
25 words
A safety ski binding according to claim 3, wherein the relation diameter of the ball head and the diameter of the ball is approximately 1:1.
Claim 6
Dependent Claim
23 words
A safety ski binding according to claim 1, wherein said locking means is a ball and said detent recess is a spherical sector.
Claim 7
Dependent Claim
23 words
A safety ski binding according to claim 1, wherein said locking means is a cone and said detent recess has a conical shape.
