FRONT SEGMENT OF SKI BINDING

Description

[0001] The invention concerns the skialp ski binding, particularly its front segment, meant to tack the front part of a ski boot in a conic (tech) placing and allows partly revolving move of a ski boot (like in cross-country skiing), that is necessary for ski walking.

[0002] Skialp ski bindings, used now, described in the European patent document, numbered as EP 1 907 078 B1 or EP 0 199 098 B1, have also used pikes to tack a ski boot in a conic placing, but on two movable arms.

[0003] The deficiency of this bindings is its high weight and difficult controlling.

[0004] The document EP 3 050 601 A1 describes a toe-piece for an Alpine ski binding, comprising: a plate fixable to a ski; a first jaw and a second jaw, arranged on the plate in such a way as to be opposite one another and each comprising an external end provided with a pin for engaging a hole of a ski boot; wherein an internal end of the second jaw is solidly constrained to the plate; and wherein the first jaw is hinged to the plate at the relative internal end with respect to an axis so as to be mobile between a first position, in which the first jaw and the second jaw are in an open configuration and the relative pins disengage from the corresponding hole of the ski boot; and a second position in wherein the first jaw and the second jaw are in a closed configuration and the relative pins can engage the corresponding hole of the ski boot. The toe-piece further comprises first elastic means associated to the first jaw.

[0005] The subject of document EP 2 662 121 A2 is a front segment of a ski binding with a holding unit which is designed to latch a ski boot and hold it pivotably about a transverse axis which runs transversely to a longitudinal axis of the ski. The holding unit consists of two movable engagement elements attached to a base plate of the front segment, each with a conical coupling means. The movable engagement elements are rotatably mounted about a bolt which is arranged on the base unit. An operating lever is connected in its lower third by means of a connecting element to an upper part of one of the movable engagement elements, the connecting element being rotatably connected to the engagement element and the lever by means of two bolts. The operating lever is supported with a lower end on the base plate, the lower end being rotatably connected by means of a bolt to a clamping element movable in a cylindrical holder of the base plate. In the holder, below the clamping element, there is a helical spring against the force of which the clamping element can be moved into the holder. The force of the spring can be adjusted by means of a screw arranged at the lower end of the holder, the screw being able to be screwed into or out of the holder.

[0006] The role of this invention is to make better a function of a front segment of binding in a way to make easier its processing, its using and to minimalize its weight. The upper described deficiency has been eliminated by this invention, that consists of the front segment of ski binding with conic pikes to tack a front part of a ski boot in a conic placing.

[0007] The front segment consist of a basement, a movable and a fixed arm with conic pikes and a controlling handle that is, in its lower third, joined with an upper pin in a rotating way in parallel with a longitudinal axis of a ski, in a connected state of the ski binding and the ski, while the controlling handle in its lower part makes a spur from the basement up to the upper pin and in the upper part makes an arm for fixing, activation and releasing of the ski boot from the front segment of the ski binding, wherein on the upper pin there is a wound spring to press the movable arm by the controlling handle towards the fixed arm in the axis of its placing on the lower pin and wherein the lower part of the controlling handle that creates a spur leans on the basement and has a dead-centre position that has to be gone through during the movement of the upper part of the controlling handle in the direction of the spring force, wherein the movable arm is moved up to a backstop position made by the basement in that it is assured against moving and in that a conic placing of a front part of a ski boot is tackable by the conic pikes, and that has to be overcome during the movement of the upper part of the controlling handle in the direction against the spring force, wherein the movable arm is released and moved away from the backstop position in that the conic placing of the front part of the ski boot is releasable from the conic pikes.

[0008] A construction of the movable arm and controlling handle enable a gripping, attachment, activation and releasing of the front segment of a ski boot with the conic placing in a way putting on of one side of the conic placing on the conic pike on the fixed arm and by the further shifting of the other part of the conic placing forwards, where the slash front part of the conic placing through the conic pike by overcoming the power of wound spring, processing through the controlling handle unbalances the movable arms in an axis of its placing on the lower pin so, that the conic pike on movable arm, pressing by the power of wound spring through the controlling handle towards the conic pike on the fixed arm, consequently set into the conic placing. Another by hand moving of the controlling handle towards processing the power of the wound spring through the dead-centre position to the backstop, made of the movable arm itself, makes this movable arm assure against the moving and releasing of the conic placing from the conic pikes on the fixed arm and movable arm, that make together a joint enabling a partly rotating motion of the ski boot in a horizontal axis upright on the longitudinal axis of the ski, needed for a walking on the skis. By the opposite motion of the controlling handle and by overcoming the dead-centre position and the power of wound string by hand or by a ski stick, the lower part, making the spur and fixing the movable arm, will release and by another motion in this way it unbalances the movable arm that cause a taking away of the conic pike on the movable arm from the other conic pike on the fixed arm insofar as it releases the conic placing and the ski boot from the front segment of ski binding.

[0010] The upper described deficiency has been eliminated by this invention, that consists of the front segment of ski binding with conic pikes 5 to tack a front part of a ski boot in a conic placing 7.

[0011] The front segment consists of a flat basement 1 with the holes to fix it on the ski. By the sides of the basement 1 there arise two arms, one fixed 2 and one movable 3; on which there are, in upper side, fixed conic pikes 5 in an opposite position. In its lower part, the movable arm 3 is in rotating way joined with the basement 1 by a bottom pin 8 in parallel with a longitudinal axis of a ski in a way to make the conic pike 5, in its upper part, movable toward the conic pike 5 on a fixed arm 2 up to backstop, made of a basement 1 itself, and vice-versa, to make the conic pike 5 on a movable arm 3 able to shift away from the conic pike 5 on the fixed arm 2.

[0012] On the movable arm 3 there is a controlling handle 4 that is, in its lower third, joined with the upper pin 9 in rotating way in parallel with a longitudinal axis of a ski and it is shaped in a way to make, in its lower part, a spur from the basement 1 to an upper pin 9 In the upper part so to enable a skier to control this handle by his hand or a ski stick.

[0013] On the upper pin 9 there is a wound spring 6, that rotates a controlling handle 4 by its own power in a way that its lower part, creating a spur, has been leaning on the basement 1 and by the further acting of this power through the upper pin 9 there is the movable arm 3 pressed toward the fixed arm 2 in an axis of its placing on the lower pin 8, up to a dead-centre position of the controlling handle 4, that the power of spring is unable to overcome, because of its partly blocking by the basement 1.

[0014] A construction of the movable arm 3 and controlling handle 4 enable a gripping, attachment, activation and releasing of the front segment of a ski boot with the conic placing 7 in a way putting on of one side of the conic placing 7 on the conic pike 5 on the fixed arm 2 and by the further shifting of the other part of the conic placing 7 forwards, where the slash front part of the conic placing 7 through the conic pike 5 by overcoming the power of wound spring 6, processing through the controlling handle 4 unbalances the movable arm 3 in an axis of its placing on the lower pin 8 so, that the conic pike 5 on movable arm 3, pressing by the power of wound spring 6 through the controlling handle 4 and upper pin 9 towards the conic pike 5 on the fixed arm 2, consequently set into the conic placing 7. Another by hand moving of the controlling handle 4 towards processing the power of the wound spring 6 through the dead-centre position to the backstop, made of the movable arm 3 itself, makes this movable arm 3 assure against the moving and releasing of the conic placing 7 from the conic pikes 5 on the fixed arm 2 and movable arm 3, that make together a joint enabling a partly rotating motion of the ski boot in a horizontal axis upright on the longitudinal axis of the ski, needed for a walking on the skis. By the opposite motion of the controlling handle 4 and by overcoming the dead-centre position and the power of wound string 6 by hand or by a ski stick, the lower part, making the spur and fixing the movable arm 3, will release and by another motion in this way it unbalances the movable arm 3 that cause a taking away of the conic pike 5 on the movable arm 3 from the other conic pike 5 on the fixed arm 2 insofar as it releases the conic placing 7 and the ski boot from the front segment of ski binding.
