Abstract

The invention is related to a ski jumping binding which allows a jumping boot (6) to be secured to a ski jumping binding in the ball-of-foot area of the boot. The ski jumping binding comprises a base (2), arranged on the ski (7) or in the ball-of-foot area of the jumping boot, with a latch (1), and correspondingly a rotational disc (5) arranged in the ball-of-foot area of the jumping boot or ski.

Description

  • The invention relates to a ski jumping binding, in the rear part of which is used prior art technology. The present invention is limited to the front part of the ski jumping binding and the jumping boot.
  • In a conventional ski jumping binding, the jumping boot is secured to the binding at the tip of the boot; a ski jumping binding fixed to the ski in the ball-of-foot area of the jumping boot has not been presented previously. The problem is a situation where a moment is produced between the thrust and its point of support, which bends the tip of the ski downwards at the moment of take-off. This is an aerodynamically disadvantageous factor regarding the jump. The air pressure exerted on the top surface of the ski presses the jumper downwards and the air resistance of the ski is not optimal. In this take-off situation, the jumper has to eliminate the moment of rotation by pushing "upwards". For the success of the jump, the situation is extremely disadvantageous.
  • In the ski jumping binding/boot combination I have developed, the ski jumping binding is secured to the ball-of-foot area of the jumping boot. With this solution, the thrust and the supporting force are obtained to the same point, whereby no disadvantageous moments are generated.
  • The present ski jumping binding is characterised by what is defined in the characterising part of the claim 1.
  • The invention is described in greater detail in the following, with reference to the accompanying drawings:
    • Figure 1
    shows the parts of the binding in order of assembly.
    Figure 2
    shows the binding/boot/ski combination on sectional plane A-A.
    Figure 3
    shows a top view of the binding/boot/ski combination.
  • The binding according to the invention is comprised of a base 2 fixed to the ski 7 with screws 8. On the base is placed a latch 1 which is fixed with a screw 3. On the jumping boot 6 is fixed a rotational disc 5 by means of a support plate 4. The rotational disc 5 is aligned with the support plate 4 by means of formed surfaces. Another alternative is to fix the rotational disc 5 to the ski 7 with the support plate 4 and, correspondingly, to fix the frame 2 to the boot 6.
  • The ski jumping binding according to the invention functions as follows. The jumping boot 6 is placed on top of the frame 2 at a certain angle so that the latch 1 penetrates through the rotational disc 5. The jumper turns the boot 6 in the direction parallel to the ski 7, whereby the boot locks into the binding. The rear part of the jumping boot is locked into the ski jumping binding as known from the prior art.
  • In an emergency, the rear part of the ski jumping binding unlocks, whereupon the front part is able to rotate and release the jumping boot from the ski jumping binding. The formed surfaces of the frame 2 and the rotational disc 5 are designed in such a way that the ski jumping binding functions safely in an emergency. It is obvious to a person skilled in the art that the invention is not limited to the example disclosed, but may vary within the scope of the claims presented below.

Claims (4)

  1. A ski jumping binding which allows a jumping boot (6) to be secured to a ski jumping binding in the ball-of-foot area of the boot, characterised in that the ski jumping binding comprises a base (2), arranged on the ski (7) or in the ball-of-foot area of the jumping boot, with a latch (1), and correspondingly a rotational disc (5) arranged in the ball-of-foot area of the jumping boot or ski.
  2. A ski jumping binding as claimed in claim 1, characterised in that the rotational disc (5) is arranged to lock the jumping boot into the binding and to release it therefrom when the jumping boot is turned sideways by a certain angle.
  3. A ski jumping binding as claimed in claim 1 or 2, characterised in that the base (2) or rotational disc (5) is attached to the ball-of-foot area of the jumping boot.
  4. A ski jumping binding as claimed in claims 1 to 3, characterised in that the rotational disc (5) is locked to the support plate (4) by means of formed surfaces.
