Definitions

  • the present invention relates to devices for moving on virgin or groomed snow, either uphill, downhill or flat, as well as crossing.
  • snowshoes allow walking step by step, avoiding any slipping, but limit the evolution to slopes of less than 18 degrees; learning is easy, but the use is relatively tedious and their limited possibilities - cross-country skiing, a narrow and long ski, with a width of less than 5 centimeters and a length of about 1.80 meters, can be used flat or on limited slopes uphill and downhill; cross-country skiing is difficult to use in ungroomed snow, for which it requires a long and tedious learning - downhill skis are relatively wider and shorter, with a width of around 7 centimeters and a length of 1 , About 80 meters for long skis and about 1.50 meters for its compact, are suitable for downhill only. They require long and tedious learning, sophisticated equipment such as special shoes, and relatively sporty skills of the user. They can be used uphill by adaptation under the ski sole of a removable anti-recoil plush. Climbing uses are limited to slopes less than about 25 degrees.
  • the object of the present invention is in particular to avoid the drawbacks of known devices by proposing a new type of short and wide skis, with particular profile, usable practically without learning, flat, uphill, downhill or crossing.
  • the invention is not intended to allow the performance of known equipment, for each in their field of application, but offers a satisfactory synthesis for an evolution in any snow: ascent, descent and crossing slopes up to 45 degrees ; not slid on flat like cross-country skiing, the particular profile of the ski also ensuring without wax or retaining plate a progression without recoil uphill on slopes going up to 20 degrees; downhill evolution on all snow by sliding like downhill skiing.
  • Special provisions ensure the stability of the ski of the present invention despite its short length, and increase its lift in loose snow; in addition, they provide an anti-back-up function which allows the use of the ski without a retaining plate on slopes up to approximately 20 degrees, the rear of the ski tending to sink into the snow. They also allow braking downhill, without a retaining plate, by tilting the user's body backwards.
  • the present invention provides a ski whose width is substantially double that of a downhill or touring ski, that is to say a width between 12 and 15 centimeters ; in addition, the length of the ski must be between five and seven times its width. These proportions are very different from those used for usual skis.
  • the ski thus produced, with a length of about 80 centimeters, is considerably shorter than all the commonly used to date, which is contrary to the currently observed development of elongation of skis and gradual abandonment of compact skis.
  • the ski according to the present invention comprises a front tip, a bearing zone and bindings.
  • the lower surface of the bearing area includes a substantially front portion plane defining a reference plane and the normal sliding plane; the front portion is connected forward with the spatula.
  • the front portion is connected to a substantially flat rear portion inclined downward and descending below the reference plane via an intermediate portion arched upward, the passage of the portion before the arched portion being effected by a progressive raising of the ski.
  • the ski is relatively steep; its stiffness is chosen so that a force of about 1200 Newton, applied perpendicularly to the middle of its upper face, produces a bending of 1 to 3 centimeters from the central area, the two ends being blocked. This stiffness is significantly greater than that of known skis.
  • the device further comprises a removable lower plate, of substantially rectangular shape, comprising studs protruding from its lower face and means for fixing and adapting it under the sole of the ski. Its length is substantially equal to a quarter of the length of the ski, and is fixed by covering the third rear quarter of the sole of the ski.
  • the ski according to the present invention comprises a front tip 1, a carrying zone 2, and bindings, not shown in the figures, allowing the adaptation of a boot on the upper surface of the ski.
  • the bearing zone 2 is arched to form a concave lower surface 3.
  • the width of the ski according to the present invention is substantially double that of a downhill or touring ski current, that is to say that it is between 12 and 15 centimeters. Its length is between five and seven times its width.
  • a standard model of length 81 centimeters, width 14 centimeters and a junior model of length 76 centimeters, width 13 centimeters can be defined. Numerous tests have shown that these proportions achieve the best compromise in use on all snow and all slopes.
  • the carrying area 2 of the ski comprises a substantially flat front portion 4 which defines a reference plane 6.
  • the front portion 4 is connected forward with the spatula 1, and provides a good surface slip.
  • the front portion 4 is connected towards the rear, by means of a convex zone, with a generally concave arched portion 3 developing above the reference plane 6.
  • the arched portion 3 is connected towards the rear with a rear part 5 plane descending below the reference plane.
  • the skier can adopt attitudes more or less leaning forward or backward.
  • an attitude slightly leaning back favors the penetration of the rear part 5 into the snow, preventing recoil.
  • a rear position favors a certain braking by penetration of the rear part 5, while a more advanced position favors the sliding by transferring the weight onto the flat portion 4.
  • the flat rear part 5 of the bearing area 2 forms with the reference plane 6 an angle between 3 ° and 6 ° in the absence of deformation, that is to say when the ski is in the state rest.
  • these values achieve a good compromise between sliding downhill and the anti-rollback function.
  • the flat front portion 4 of the bearing zone 2 has a length of between one third and half of the total length of the ski.
  • the stiffness of the ski is chosen so that a force of approximately 1200 Newton, applied perpendicularly to the middle of its upper face, produces a bending of 1 to 3 centimeters from the central zone, the ends being blocked.
  • the structure of the ski comprises a polyester core reinforced with glass fibers or carbon-free fibers, comprising upper longitudinal and transverse ribs 7 shown in dotted lines in FIG. 3.
  • An upper cover 8, represented in FIG. 4, is attached and joined to the polyester core 9. The joining can be carried out hot by thermoforming, or by any other means such as bonding, welding.
  • the device further comprises a removable lower plate 10 intended to be attached to the lower surface of the ski.
  • This plate 10 shown in Figure 2, is of substantially rectangular shape, and has studs 11 protruding from its underside, and fixing means for adapting and fixing it under the sole of the ski.
  • Two hooked guide tabs 12 and 13 are arranged on the front part 14 of the upper face of the plate, and are shaped to allow the ski to pass between them and its maintenance as shown in the figures.
  • the plate also comprises, on the rear part 16 of its upper face, longitudinal vertical lugs 17 and 18 of spacing slightly greater than the width of the ski, as shown in FIG. 2.
  • the device for fixing the plate to the ski further comprises stops 19 and 20 attached to the upper surface of the ski, and against which the guide tabs 12 and 13 come to bear, as shown in FIG. 3.
  • the ski comprises in addition upper angles 21 and 22 attached to the upper surface.
  • the tabs 18 and 17, and the angles 21 and 22 are provided with corresponding holes 23 and 24, as shown in FIG. 4, for the passage of assembly rods 25 and 26 connected by an elastic band 27 passing behind a tension pin 28 attached to the upper surface of the rear part 5 of the ski.
  • the adaptation of the plate on the ski is carried out as follows; the front part of the ski is slid between the guide tabs 12 and 13 of the plate, and, when these tabs are in abutment against the stops 19 and 20, the upper surface of the plate is pressed against the lower surface of the ski, putting related the holes 23 and 24, the rods 25 and 26 are inserted which are bent as shown in the figures, and the elastic band 27 is passed behind the pin 28.
  • the plate 10 can be produced by any means, and for example by cutting and folding portions of a sheet forming a plate.
  • the bindings can be downhill ski bindings, but preferably touring or cross-country bindings with the possibility of blocking the boot heel on the ski for the descent.
  • the plate 10 has a length substantially equal to a quarter of the length of the ski, and the stops 19, 20 and angles 21, 22 are arranged so that the plate is positioned to cover the third rear quarter of the sole of the ski.
