Definitions

  • the present invention relates to the sport of skiing and more precisely it relates to a monoski having a ski-boots binding system for a monoski skiing.
  • the invention relates to a ski-boots binding unit for a monoski.
  • Three types of monoski are known, i.e. sport equipment consisting in a single ski having a couple of ski-boot bindings so that the skier can go downhill on the snow with a single ski.
  • a first type of monoski provides two parallel bindings arranged longitudinally on the ski.
  • a second type of monoski is the snowboard, which provides a couple of bindings parallel to each other but transversal to the ski, that consists in a board with larger width than a normal ski.
  • a first problem is that a very low distance between the rear and front bindings is necessary. On the contrary, the skier would not ski with legs close to each other, and would be obliged at the same time to have the feet aligned on the same ski axis, whereby skiing is not comfortable.
  • ski-lifts must. be easily allowed, and this requires that a ski boot has to be released, whereas the other remains bound to the monoski.
  • a binding system having a front binding and a rear binding that are arranged aligned behind each other in longitudinal direction with respect to the ski.
  • Said binding system comprises a toe piece for the front ski-boot, a common centre piece and a heel piece for the rear ski-boot.
  • the characteristic is that the common centre piece has parts that are movable longitudinally in the locking step, whereby the lock of a ski boot is possible with the locking movement of the other ski-boot.
  • the common centre piece can move longitudinally from a first forward position to a second rearward position, biased by a resilient reaction.
  • the common centre piece is such that locking the rear ski-boot is possible with a locking movement of the front ski-boot.
  • means are provided for locking a ski-boot singularly, for catching ski-lifting means.
  • the common centre piece can slide up to locking in the rearward position of skiing, wherein it can keep locked both the two ski-boots and the single front ski-boot, since after releasing the rear ski-boot the front ski-boot can be locked singularly.
  • the rear binding has a rear plate arranged between ski and ski-boot and a raised portion of predetermined height. This way, the rear ski-boot has the boot sole inclined in longitudinal direction with respect to the ski.
  • front and rear plates together with the common centre piece and the ski-boots binding means are provided as a single binding unit, to be mounted integrally on the ski.
  • the rear plate is rotatable about a pin transversal to the ski provided at the common centre piece.
  • the skier can rotate integrally the rear ski-boot and the rear binding integrally to the plate.
  • the raised portion has predetermined adjustable height. Furthermore, it can be displaced from a raised position to a rest position, in order to allow the rear plate to rest horizontally when the ski is not used.
  • the front binding can have a front support plate that is arranged between the ski and the ski-boot.
  • the rear place and the front plate, or the relative bindings are mounted so that the ski-boot has an inclination in a transversal direction, and in particular so that each ski-boot is inclined towards outside. This can be done for example with shims arranged between the plates and the support of the ski-boot or making directly inclined plates.
  • the common centre piece can rotate about an axis orthogonal to the plane of the ski. This way, in case of fall of the skier, the automatic release of the ski-boots is possible.
  • the rotation of the rear toe piece and of the front heel piece is advantageously integral, so that the ski-boots are released at the same time.
  • a monoski according to the present invention is used by a skier 2 that wears a right ski-boot 3 and a left ski-boot 4.
  • the right boot 3 and the left boot 4 are connected to the monoski 1 by a ski-boots binding system comprising respectively a rear binding 5 and a front binding 6.
  • Ski-boots bindings 5 and 6 are arranged on the monoski 1 aligned longitudinally in rearward position towards tail la and forward position towards tip 1b, respectively.
  • the rear 5 and front 6 ski-boots bindings are formed by a single unit that comprises respectively a rear toe piece 25 and a front toe piece 26 as well as a front heel piece 35 and a rear heel piece 36 for the ski-boots 3 and 4. More precisely, the rear toe piece 25 and the front heel piece 36 are associated to a common centre piece 40 so that they can:
  • the rear binding 5 has a rear support plate 15 located between ski 1 and rear boot 3. Also front binding 6 has a front support plate 16 that is arranged between ski 1 and front boot 4. Rear plate 15 has a raised portion 15a of predetermined height, whereby the rear ski-boot 3 has the boot sole inclined forward in longitudinal direction with respect to the ski 1. Rear plate 15 can rotate at the common centre piece 40 and raised portion 15a can be rotated in a rest position shown in figure 2A, wherein rear plate 15 is horizontal.
  • Rear plate 15 can also rotate, during the skiing, up to a position indicated with a light dotted line in figure 2 that is more inclined than that of figures 2 and 2A, , thus allowing the skier to rotate integrally the ski-boot, in order to move the rear knee when skiing.
  • the common centre piece 40 as above said, further to the rotation of rear plate 15, allows two further movements, shown in figures 2D and 2E. More precisely (figure 2B, 2D) an integral braked rotation of rear toe piece 25 and of front heel piece 36 about pin 41 is allowed. This way, there is an automatic emergency release of the ski-boots in case of fall. Furthermore a longitudinal translation of common centre piece 40 (figure 2E) is possible for:
  • common centre piece 40 can move rearwards longitudinally sliding in a guide not shown provided in front plate 16, in a way biased resiliently up to a stop position. Then, for preparing to skiing, front ski-boot 4 is put against front toe piece 26, so that the heel of front ski-boot 4 engages with front heel piece 36. In this position front ski-boot 4 is released. By means of fastener 27 front ski-boot 4 can be locked. This causes a rearward movement of common centre piece 40, and then integrally to it of front heel piece 36 and of rear toe piece 25, from a first forward position to a second rearward position. In presence of rear ski-boot 3 between rear toe piece 25 and rear heel peace 35, it is locked by the rearward movement of common centre piece 40.
  • front ski-boot 4 remains in any case locked. This allows rear ski-boot to be free for example for catching ski-lifting means.
  • front ski-boot 4 is free and moves slightly forward, since the common centre piece 40 is free of moving forward. This allows rear ski-boot 3 to be freed as well.
  • front toe piece 26 and the rear heel piece 35 can be adjusted in distance with respect to common centre piece 40, in order to allow the lock of ski-boots of whichever size.
  • the adjustment is possible by means of adjusting slotted plates available in the market and then not described in more detail.
  • Plates 15 and 16 and the relative ski-boots bindings are a single binding unit 100 that can be provided as a whole by the manufacturer and directly fastened to the ski 1.
  • rear and front ski-boot bindings 5,6 comprise respectively a rear toe plece 25 and a front toe piece 26 as well as a rear heel piece 35 and a front heel piece 36.
  • the rear binding 5 has also a rear plate 15 located between ski 1 and rear boot 3.
  • Rear plate 15 has a raised portion 15a of predetermined height whereby rear boot 3 is arranged with sole inclined forward in longitudinal diroction with respect to ski 1.
  • Rear plate 15 can rotate about a transversal axis at common centre piece 40, and raised portion 15a can rotate as well to a rest position shown in figure 3B, wherein plate 15, indicated in that position with a dotted line, is horizontal.
  • the rear pieces 25 and 35 are independent and can have a snap engagement for locking the respective ski-boots against the toe pieces 26 and 36.
  • ski 1 can be either a standard ski, for example with central width of 6,5 cm, or a special ski with larger width.
  • rear plate 15 and front plate 16 have an inclination on a transversal direction, shown in figures 8 and 9, so that the boot 3 and 4 are always inclined outwardly.
  • front plate 16 has left thickness 16' larger than right thickness 16
  • rear plate 15 has right thickness 15" larger than left thickness 15'.
  • the different thicknesses 15', 15", 16' and 16" may also be obtained with appropriate shims arranged on the plates under the ski-boot bindings.
  • toe piece 25 of rear binding 15 and heel piece 36 of front binding 16 are integrated in a single intermediate piece 56.
  • heel piece 36 like that of figures 3A, 3B and 5
  • toe piece 25 of figures 6 and 7 can be inserted in a recess made in heel piece 36 same
  • spring means for a safety release of the rear boot can be provided that operate by rotating under stress on toe piece 25 similar to those provided in front toe piece 26 of known art.
  • the front plate and the rear plate can be made, as shown in figures 6 and 7, by a single plate element 100 connected to the ski and shaped in order to have a front plain portion 16 inclined transversally like in fig. 8 and a rear portion 15 raised longitudinally in 15a and inclined transversally in direction opposite to the front portion like in fig. 9.
  • intermediate piece 56 can be slidable longitudinally with respect to ski 1, whereby the locking movement of the rear boot 3 causes also the front binding heel piece 4 to move forward, since the intermediate piece is pushed by the rear boot 3 against front boot 4, in turn engaging with front binding toe piece 26.
  • the slidable intermediate piece 56. once reached the locking position indicated with a continuous line in figure 10, is locked automatically by means of a click mechanism not shown, and that can be unlocked by skier 2 once released the rear boot 3. If the rear boot 3 is released, front boot 4 can remain locked for running like on a scooter.
  • the monoski according to the invention is new with respect to a monoski with parallel bindings and has the following advantages.
  • First of all skiing with sharp turns is allowed owing to the advantageous position of the legs and to the width of the ski.
  • the movement like a scooter is allowed in case of plain snow fields or slight slopes, or for catching ski-lift means.
  • the boot that remains fastened to the ski is centred transversally with respect to the ski and does not cause lateral inclination.
