Abstract
Abstract A ski binding is mounted for pivotal, vertical movement with respect to a ski, preferably through a base plate, and is normally held in boot-engaging position by cam means resiliently urged into holding position. An upwardly directed force overcomes the force imposed by said resiliently urged cam and effects release. The base structure of said binding is also mounted for horizontal pivoting movement with respect to the ski, preferably through said base plate if one is used, and is normally held by means including cam means centered with respect to the ski. Said last-named cam means is arranged to require upward movement of a portion of said binding in order to permit lateral movement about said last-named pivot, said portion of said binding being the same portion which moves upward in response to a vertical stress. Hence, upward movement of said portion of said binding releases same in both vertical and sideward directions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
204 words
In a releasable ski binding having a base plate, a base member pivotally mounted on said base plate for movement about a vertical axis, a sole holder and support means on said base member for supporting said sole holder for pivotal movement about a horizontal axis and for movement with said base member about said vertical axis, the improvement comprising: first and second separate locking means for releasably locking said sole holder to said base plate and said base member; and a single spring acting on said first and second locking means effecting a resistive force for controlling the magnitude of force required to effect a release of said first and second locking means and said ski binding, one of said first and second locking means including blocking means for positively preventing a purely horizontal movement of said sole holder relative to said base plate about said vertical axis when said ski binding is in a closed position while simultaneously permitting a pivoting movement of said sole holder about both of said horizontal and vertical axes in response to a combined horizontal and vertical force being applied to said sole holder which is greater in magnitude than the resistive force of said single spring.
Claim 2
Dependent Claim
204 words
In a releasable ski binding having a base plate, a base member pivotally mounted on said base plate for movement about a vertical axis, a sole holder and support means on said base member for supporting said sole holder for pivotal movement about a horizontal axis and for movement with said base member about said vertical axis, the improvement comprising: first and second separate locking means for releasably locking said sole holder to said base plate and said base member; and a single spring acting on said first and second locking means effecting a resistive force for controlling the magnitude of force required to effect a release of said first and second locking means and said ski binding, one of said first and second locking means including blocking means for positively preventing a purely horizontal movement of said sole holder relative to said base plate about said vertical axis when said ski binding is in a closed position while simultaneously permitting a pivoting movement of said sole holder about both of said horizontal and vertical axes in response to a combined horizontal and vertical force being applied to said sole holder which is greater in magnitude than the resistive force of said single spring.
Claim 3
Dependent Claim
103 words
The improvement according to claim 1, wherein the other of said first and second locking means includes a first cam roller mounted on said sole holder for rotation about a horizontal axis and a first contoured track means on said base member, said first cam roller engaging said first track means so that upon a relative movement between said sole holder and said base member, said first cam roller will move along said first track means and effect a controlled relative movement between said sole holder and said base member about either said horizontal axis or both of said horizontal and perpendicular axes.
Claim 4
Dependent Claim
77 words
The improvement according to claim 2, wherein said one of said first and second locking means includes a second contoured track means fixedly secured to said base plate; and wherein said blocking means is defined by a recess in said second track means at the central region of movement of said sole holder about said vertical axis and adapted to receive a second cam roller therein to hold said sole holder against said pure horizontal lateral movement.
Claim 5
Dependent Claim
75 words
The improvement according to claim 3, wherein said recess means in said second track means has a pair of horizontally and laterally spaced vertical walls and a horizontal bottom wall extending therebetween; and wherein said second cam roller has a diameter which is slightly less than said horizontal spacing between said vertical walls and the depth of said recess means to said bottom wall is slightly greater than the radius of said second cam roller.
Claim 6
Dependent Claim
107 words
The improvement according to claim 2, wherein said first contoured track means includes a lever pivotally secured to said base member about a second horizontal axis parallel to said first-mentioned horizontal axis, said lever having a cam surface thereon, said single spring engaging said lever and urging said lever and said sole holder about said second horizontal axis toward a ski boot holding position, said first cam roller engaging said cam surface and, upon a movement of said sole holder about said first horizontal axis, effecting a pivoting of said lever against said resistive force of said single spring to control the release of said ski binding.
Claim 7
Dependent Claim
185 words
The improvement according to claim 2, wherein said one of said first and second locking means includes a second contoured track means fixedly secured to said base plate; and wherein said blocking means is defined by a recess in said second track means at the central region of movement of said sole holder about said vertical axis and adapted to receive a second cam roller mounted on said sole holder therein to hold said sole holder against said pure horizontal lateral movement; and wherein said first contoured track means further includes a lever pivotally secured to said base member about a second horizontal axis parallel to said first-mentioned horizontal axis, said lever having a cam surface thereon, said single spring engaging said lever and urging said lever and said sole holder about said second horizontal axis toward a ski boot holding position, said first cam roller engaging said cam surface and, upon a movement of said sole holder about said first horizontal axis, effecting a pivoting of said lever against said resistive force of said single spring to control the release of said ski binding.
Claim 8
Dependent Claim
75 words
The improvement according to claim 1, wherein said one of said first and second locking means includes a contoured track means fixedly secured to said base plate; and wherein said blocking means is defined by a recess in said contoured track means at the central region of movement of said sole holder about said vertical axis and adapted to receive a cam roller therein to hold said sole holder against said pure horizontal lateral movement.
