Abstract
Abstract Heel and toe binders are opposed on a ski and bear against the sole portions at heel and toe of a ski boot. The binders are substantially the same, each having a bracket sustaining an adjustable spring-loaded screw and a thrust member articulately joined to the screw. A universal joint on the thrust member is lodged in an arm of the bracket. A boot contact yoke is fastened to the thrust member. The yoke is adjustable perpendicular to the ski with respect to the thrust member. The yoke of the toe binder engages the top of the extending boot sole. The yoke of the heel binder engages the cable groove of the boot heel. Each binder yields to release the boot if pressure in excess of the spring loading on the thrust member impinges in either horizontal or vertical direction above the ski surface. The rear binder may have a horizontally extending lever which may be depressed at its rearward end by hand or by the ski pole to release the binding from the boot heel.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
295 words
Clamping apparatus for binding to a ski a boot having toe and heel bearing areas, the apparatus comprising a clamp bracket adapted to be secured to the ski adjacent the toe bearing area, a clamp bracket adapted to be secured to the ski adjacent the heel bearing area, each bracket comprising a base and opposed spaced vertical arms, a thrust member journaled in one arm of each bracket, each of said thrust members including a semispherical journal joint residing movably in the bracket arm, an extending curving yoke adapted to bear on the adjacent bearing area of the boot, a fulcrum plate and a pintle; an actuation arm extending horizontally from the fulcrum plate above the load member away from the thrust member, a threaded load member journaled in the other arm of each bracket, a threaded stop on each load member, a compression spring about each load member between the stop and the bracket arm, each load member being articulately connected to the pintle of a thrust member such that spring force is transmitted through the thrust member to the bearing area of the boot adjacent the respective bracket, means on the load member for relative rotation of the load member with respect to the stop to alter the spring tension force and change the load of the thrust member against the boot portion; said fulcrum plate bearing against adjacent parts of the bracket to act as a fulcrum for motion of the thrust member with respect to the bracket; the load member and the thrust member of each being so journaled as to be free to move with respect to the bracket in both horizontal and vertical directions when boot motion forces on the thrust member exceed the tension force of the spring.
Claim 2
Dependent Claim
295 words
Clamping apparatus for binding to a ski a boot having toe and heel bearing areas, the apparatus comprising a clamp bracket adapted to be secured to the ski adjacent the toe bearing area, a clamp bracket adapted to be secured to the ski adjacent the heel bearing area, each bracket comprising a base and opposed spaced vertical arms, a thrust member journaled in one arm of each bracket, each of said thrust members including a semispherical journal joint residing movably in the bracket arm, an extending curving yoke adapted to bear on the adjacent bearing area of the boot, a fulcrum plate and a pintle; an actuation arm extending horizontally from the fulcrum plate above the load member away from the thrust member, a threaded load member journaled in the other arm of each bracket, a threaded stop on each load member, a compression spring about each load member between the stop and the bracket arm, each load member being articulately connected to the pintle of a thrust member such that spring force is transmitted through the thrust member to the bearing area of the boot adjacent the respective bracket, means on the load member for relative rotation of the load member with respect to the stop to alter the spring tension force and change the load of the thrust member against the boot portion; said fulcrum plate bearing against adjacent parts of the bracket to act as a fulcrum for motion of the thrust member with respect to the bracket; the load member and the thrust member of each being so journaled as to be free to move with respect to the bracket in both horizontal and vertical directions when boot motion forces on the thrust member exceed the tension force of the spring.
Claim 3
Dependent Claim
70 words
Apparatus in accordance with claim 1 wherein each thrust member further comprises a shank projecting from the journal joint, a first vertical attachment plate on the shank, a second vertical attachment plate on the curving yoke, and means for securing one vertical plate to the other at selected vertical relationships so as to vary the vertical position of the curving yoke with respect to the top surface of the ski.
Claim 4
Dependent Claim
224 words
Clamping apparatus for binding to a ski a boot having toe and heel bearing areas, the apparatus comprising a clamp bracket adapted to be secured to the ski adjacent the toe bearing area, a clamp bracket adapted to be secured to the ski adjacent the heel bearing area; each bracket comprising a base and a vertical arm, a thrust member journaled in the arm of each bracket; each of said thrust members including a semispherical journal joint residing movably in the bracket arm, an extending yoke adapted to bear on the adjacent bearing area of the boot, a fulcrum plate attached to the journal joint, a load member biased to bear against the thrust member to load the yoke against the bearing area of the boot adjacent the respective bracket; said fulcrum plate bearing against adjacent parts of the bracket to act as a fulcrum for motion of the thrust member with respect to the bracket, an actuation arm secured to and extending horizontally from the fulcrum plate above the load member away from the thrust member; the load member and the thrust member of each clamp bracket being so journaled as to be free to move with respect to the bracket in both horizontal and vertical directions when boot motion forces on the thrust member exceed the bias force on the load member.
Claim 5
Dependent Claim
224 words
Clamping apparatus for binding to a ski a boot having toe and heel bearing areas, the apparatus comprising a clamp bracket adapted to be secured to the ski adjacent the toe bearing area, a clamp bracket adapted to be secured to the ski adjacent the heel bearing area; each bracket comprising a base and a vertical arm, a thrust member journaled in the arm of each bracket; each of said thrust members including a semispherical journal joint residing movably in the bracket arm, an extending yoke adapted to bear on the adjacent bearing area of the boot, a fulcrum plate attached to the journal joint, a load member biased to bear against the thrust member to load the yoke against the bearing area of the boot adjacent the respective bracket; said fulcrum plate bearing against adjacent parts of the bracket to act as a fulcrum for motion of the thrust member with respect to the bracket, an actuation arm secured to and extending horizontally from the fulcrum plate above the load member away from the thrust member; the load member and the thrust member of each clamp bracket being so journaled as to be free to move with respect to the bracket in both horizontal and vertical directions when boot motion forces on the thrust member exceed the bias force on the load member.
