Cross country plate ski binding

A binding comprised of a uni-flexible sole plate extending the length of the wearer's foot, said sole plate firmly attached with screws or other fasteners to a ski or other equipment at the forward end of the sole plate, toe brackets, one on each side of the foot at the toe, each toe bracket formed from a single piece of substantially smooth wire, each said wire toe bracket formed with a portion beneath the toe at the forward end of said sole plate, and a raised portion extending up alongside the toe, each said raised portion providing a straight portion of wire around which is looped a strap closure equipped toe strap that passes over the top of the toe and connects the toe bracket raised portions on opposite sides of the toe, said straight portion of wire inclined downward from rear to front alongside the toe at an angle matching the lay of said looped toe strap, and said raised straight portions on opposite sides of the toe forwardly converging, said wire toe bracket portion beneath the toe comprising the two end portions of said single piece of substantially smooth wire, said two wire end portions spaced apart and parallel to each other, and extending transverse to the length of said sole plate beneath the toe, each said wire end portion clamped, together with a corresponding wire end portion from the wire toe bracket on the opposite side of the toe, between said sole plate and a channel in a toe clamp plate, said toe clamp plate channels, two in number, dimensioned to hold two wire end portions from opposite toe brackets against said sole plate, parallel, overlapping, and adjacent to each other, each said toe clamp plate channel shaped to exert a frictional clamping force along a single line of contact on each toe bracket wire end portion, said line of contact positioned along the length of each side of said channel at a depth into the channel slightly greater than half the toe bracket wire diameter, said clamping force between sole plate and toe clamp plate upon said toe brackets generated by screws or other tightenable fasteners, said wire toe brackets laterally adjustable by means of loosening said screws or other tightenable fasteners, heel brackets, one on each side of the foot at the heel, each heel bracket formed from a single piece of substantially smooth wire, each said wire heel bracket formed with a portion beneath the heel at the rear end of said sole plate, and a raised portion extending up alongside the heel, said wire heel bracket raised portion providing a section of wire around which is fastened one end of a strap closure equipped heel strap, the free end of said heel strap passing up behind the heel, over the top of the foot, and down around behind the heel to a point of fastening around a section of wire on the heel bracket raised portion of the opposite wire heel bracket, said wire heel bracket portion beneath the heel comprising the two end portions of said single piece of substantially smooth wire, said two wire end portions spaced apart and parallel to each other, and extending transverse to the length of said sole plate beneath the heel, each said wire end portion clamped, together with a corresponding wire end portion from the wire heel bracket on the opposite side of the heel, between said sole plate and a channel in a heel clamp plate, said heel clamp plate channels, two in number, dimensioned to hold two wire end portions from opposite heel brackets against said sole plate, parallel, overlapping, and adjacent to each other, each said heel clamp plate channel shaped to exert a frictional clamping force along a single line of contact on each heel bracket wire end portion, said line of contact positioned along the length of each side of said channel at a depth into the channel slightly greater than half the heel bracket wire diameter, said clamping force between sole plate and heel clamp plate upon said heel brackets generated by bolts or other tightenable fasteners connecting said sole plate to said heel clamp plate, said wire heel brackets laterally adjustable by means of loosening said bolts or other tightenable fasteners.
