Definitions

  • the invention relates to an alpine ski with a device attached to the rear end portion of the ski for influencing the sliding behavior of the ski.
  • Short alpine skis and firing ladders are easy to turn, but at higher speeds and on hard snow their short edges lose their grip.
  • the fins can only be mounted far after the ski boots, at least 18 cm after the rear shoe end. The reason is the anchoring of the fin-carrier behind the ski binding.
  • This invention displaced the foremost fin into the ski axis, thereby canceling random moments of force generated at the laterally mounted fins.
  • a ski has at least two down-up-extension projections .., at least one on each side of the longitudinal axis of the ski ! (Abstract, 1st movement) "... projections, one on each side of the longitudinal axis of the ski " (column 1, lines 14 to 15), “... each side wall having a number of resesses " (column 1, lines 33 to 34) "... said channel member having a pair of side walls one of which depends on each side " (Column 3, lines 9 to 11) "... each of said side walls having at least one recess ! (column 3, lines 15 to 18)
  • the subject of the application does not use any moving parts, instead of a Harsch iron or a slightly corrugated thickening of the carrier he has larger active plates, which serve primarily the directional control and replace the ski edge in this function entirely.
  • the active plates are located above the plane of the sliding surface.
  • the invention is based on our patent A 412/2006 and has as its object to improve the effectiveness of the Finns on ice, hard natural snow and groomed slopes.
  • the front fins should approach very close to the heel in order to make the convulsive attitude of the reserve superfluous. When this succeeded, it turned out that the front fins, which now cut with great force, lead to great restlessness of the skis. Solving this problem was the second object of the new invention.
  • the diagonal beam according to our patent A 412/2006 was first shifted 20-30 cm forward (ie towards the tip of the ski). He touches the ski body between the front and the back of the ski binding. The back part of the binding is mounted on the carrier itself. The inclination of the carrier was greatly reduced. It is only 4 to 8 degrees instead of earlier 8 to 20 degrees
  • fins vertical fin-like plates
  • the fins are attached to one with the ski body in the region of the rear binding part firmly connected carrier.
  • the Finns improve the grip of the ski on the snow surface.
  • the position of the Finns behind the ski boot stabilizes the direction.
  • the small overall length of the fins ensures easy turning without prior ski relief. Unlike a carving ski, no turning radius is preferred.
  • the ski and the carrier cut out V-shaped ("dovetail"). Isosceles triangles with a ratio of height to base of approx. 1: 1 are cut symmetrically.
  • the total length of the tested prototypes incl. Structure varied between 92 and 170 cm.
  • a light template of the driver lifts the Finns out of the snow and loads the ski scoops or ski edges. In this position, the skier can steer by the usual swinging or "carving".
  • Striking in this invention is the great variability in the selection and the design of the fins and their girders.
  • Special skis for firn, steep and / or icy slopes, hard cross grooves or the fast ride in mixed terrain arise from different combinations of shapes, Sizes and positions of the fins.
  • the skiing characteristics of the ski can be described for the first time adapting to changed circumstances in a tour or departure eg by replacing the structure directly on the slope.
  • the subject invention is shown, for example. It show the Fig.1 and 1b a ski according to the invention for groomed Piste, deep snow, natural terrain with hard places, heavy Snow on and off the slopes and for forest runs. His length is 110 cm, the slope of the carrier is 5 degrees, the only fin is made of 3 mm aluminum.
  • first embodiment is on a conventional, 110 cm long short ski 1 between the front part of the binding 4 and the rear part of the binding 2 at an angle of 5 degrees obliquely ascending, 40 cm long carrier. 3 with the same cross-section as the underlying Ski 1 mounted.
  • the resulting between ski body 1 and the carrier 3 wedge-like space is covered from both sides with a metal plate (here of 3 mm aluminum), which is firmly screwed with ski and the carrier.
  • Stainless screws were used with recessed heads 4.5 x 35.
  • the fin On the sliding base 5 of the carrier, the actual direction control is attached: the fin. 7 This trapezoidal plate is oriented vertically in the direction of travel, its cutting edge points down and forward. It is manufactured as a T-profile 35 mm x 35 mm made of 3 mm aluminum. The T-profile is connected to the underside 5 of the carrier with stainless screws with recessed heads 5.0 x 20 firmly screwed.
  • V-shaped cutouts at the end of support 3 and at the end of ski body 1 can not break hard snow and ice, they only provide soft and medium-hard surface for better directional stability.
