Description

Ski bindings

Technical field

BACKGROUND OF THE INVENTION The present invention relates to ski bindings intended to fix a foot to a ski.

BACKGROUND ART

All known leg-ski solutions are based on the use of a special ski boot, which is attached to the heel and toe elements before skiing. The construction of such a boot must ensure the transfer of all necessary control forces to a solid sole that is fixed to the ski binding. This construction must be sufficiently strong and rigid, but at the same time it must be free for certain movements. The result is a shoe more or less functional for skiing. However, this ski boot is not suitable for walking on known ski bindings. Other drawbacks are relatively high weight and bulky ski boots and structurally complex ski bindings.

SUMMARY OF THE INVENTION

Said drawbacks are eliminated by a ski binding affixed to a ski or to a ski affixed to a ski or safety plate binding plate and comprising a heel stop, a toe fixation element, a toe stopper and a base body for fixing other leg portions, according to the present invention.

characterized in that a body of a bracket provided with a height adjusting member is pivotally mounted in the base body, and a calf support with a shin fixation member is rotatably mounted on said height adjusting member, the binding further comprising a bracket control member and a member for instep fixation. In a preferred embodiment of the binding, the pivoting movement control member of the holder consists of a spring located on a bolt between the holder body and a nut mounted on one end of the bolt, the opposite end of which is mounted on a shaft rotatably supported in the base body.

The main advantage of the ski binding according to the invention is that it does not need any special footwear for its good function, since it is not possible to use footwear that is suitable for any other activity. Thus, any shoe sufficiently protecting the foot from the accompanying conditions, in particular cold and / or moisture, may be used for the binding according to the invention, the shoe does not even have to have a sole tube, since the transfer of corresponding forces is completely different in the binding according to the invention bindings. In principle, the transmission of the main forces is secured to the binding according to the invention by the calf support holder and its connection with the ski. The headrest 10 is individually adjustable in height in the holder. In its lower part, the body with the calf support bracket is mounted so that the calf support bracket can be pivoted along an axis perpendicular to the longitudinal axis of the ski and parallel to the ski surface. Moreover, this pivoting movement is controlled in a controlled manner. The result is a controlled movement of the calf section of the foot that is transmitted to the ski to avoid any unacceptable strain or possibly damage to the foot in the ankle area. Further advantages of the present invention are low weight, easy to move to transport or storage position, simple construction and hence easy manufacturing.

Examples for carrying out the invention

The ski binding according to the present invention is attached to the ski or to the ski pad 1 attached to the ski or to the safety plate binding plate and comprises a heel stop 2 and a instep fixing element 3 which is formed, for example, by a strap. whereby the heel side stops are also formed for binding. Furthermore, the binding comprises a tip fixing element 4, which again is preferably formed by a strap and which is connected to the washer 1 by the fastening members 21, whereby lateral stops of the tip are also formed for binding. The binding further comprises a toe stop 5 and a base body 6 for fixing other parts of the foot. In the base body 6, therefore, the body 16 of the holder 7 provided with the height adjusting member 8 is supported by the shaft 18 and the height adjusting member 8 is rotatably supported by the shaft 9 by a calf support 9 with a shin fixation element. wherein the binding further comprises a member

For controlling the swivel movement of the holder 7.

The pivoting movement member JJ consists of a spring J2 located on a screw J3 between the holder body 16 and a nut 14 mounted at one end of the screw 13, the opposite end of which is mounted on a shaft J7 rotatably mounted in the base body 6. Preferably, a washer 15 is positioned on the screw 11.

The ski binding according to the invention is prepared from the transport position for skiing by first assembling a member 11 for controlling the pivoting movement of the holder 7 by passing the screw JJ through a groove in the body J6 of the holder 7, 7 between the holder body 16 and the nut 14, optionally supplemented by a washer 15 located on the screw 11. Also, the calf support 9 has to be rotated from the transport position around the shaft 19 to a position ready for gripping the foot. After that, the skier can start attaching the shoe to the ski with any shoes. First insert the shoes between the heel stop 2 and the toe stop 5 and then secure it with the instep fixing element 3 and the toe fixing element 4. Further, the skier adjusts the height of the calf support 9, preferably by sliding the member 8 in the holder 7, and then the skier completes the leg attachment to the ski by fixing the tibia in the binding with the tibia fixation element 10 on the holder 7.

For binding according to the invention, during the skiing the transfer of the main forces is ensured by the holder 7 with the calf support 9 and its connection with the ski. In its lower part, the body 16 with the calf support 7 is supported on the base body 6 so that the calf support 7 can be pivoted along an axis perpendicular to the longitudinal axis of the ski, specifically around the shaft 18, and parallel to the ski surface. . In addition, this pivoting movement is controlled by the pivoting movement control member 7. The result is a controlled movement of the calf portion of the foot that is transmitted to the ski avoiding any unacceptable strain or possibly damage to the foot in the ankle area. The calf support 9 is individually adjustable in height by the height adjusting member 8 in the holder 7.

The main advantage of the ski binding according to the invention is that it does not need any special footwear for its good function, since it is possible to use footwear which is suitable for any other activity. Thus, any shoe sufficiently protecting the foot from the accompanying conditions, in particular cold and / or moisture, may be used for the binding according to the invention. This shoe does not even have to have a completely rigid sole, since the transmission of corresponding forces is completely different bindings as explained in the previous paragraph. Further advantages of the present invention are low weight, easy positioning in transport or storage position, simple construction and hence easy manufacturing.
