[0001] The invention concerns the sklalp 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.

Background Art

[0002] Sklalp ski bindings, used now, described In the European patent document, numbered as EP 1907078 B1 or EP 199098 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. Summary of Invention

[0004] 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 mlnimallze Its weight. The upper described deficiency have 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 Ih a conic placing.

[0005] The front segment consists of a flat basement with the holes to fix It on the ski. By the sides of the basement there arise two arms, one fixed and one movable; on which there are, In upper side, fixed conic pikes In an opposite position. In Its lower part, the movable arm Is In rotating way joined with the basement by a bottom pin parallery with a longitudinal axis of the ski In a way to make the conic pike, in Its upper part, movable toward the conic pike on a fixed arm up to backstop, made of a basement itself, and vice-versa, to make the conic pike on a movable arm able to shift away from the conic pike on the fixed arm.

[0006] On the movable arm there is a controlling handle that is, in its lower third, Joined with the upper pin In rotating way parallely 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 to an upper pin In the upper part so to enable a skier to control this handle by his hand or a ski stick.

[0007] On the upper pin there Is a wound spring, that rotates a controlling handle by its own power in a way that its lower part, creating a spur, has been leaning on the basement and by the further acting of this power through the upper pin there Is the movable arm pressed toward the fixed arm In an axis of its placing on the lower pin, up to a dead-centre position of the controlling handle, that the power of spring Is unable to overcome, because of Its partly blocking by the basement.

[0008] A construction of the movable arm and controlling handle enable a gripping, attachement, 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 handy 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 handy 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.

Brief Description of Drawings [0009] The invention has been clarified by drawings - picture 1 represents the view on the front segment of the ski binding. In picture 2 there Is a plan view and projection of the front segment of ski binding. Picture 3 represents the way of gripping and fixing of the front segment of the ski boot. In the picture 4 there is a way of releasing of the front segment of the ski boot.

Description of Embodiments

[0010] The upper described deficiency have 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 fiat basement 1 with the holes to fix it on the ski. By the sldee 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 fi parallely with a longitudinal axis of a ski in a way to make the conic pike fi, 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 fi there Is a controlling handle 4 that is, in its lower third, joined with the upper pin fi In rotating way parallely 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 fi 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 fi there Is a wound spring fi, 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 & there is the movable arm fi pressed toward the fixed arm 2 in an axis of Its placing on the lower pin fi, 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, attachement, 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 handy 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 handy 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.
