  • This invention concerns a ski of the kind in which a single ski body member formed with a gliding surface is provided with two ski bindings fixed on said ski body member in side by side arrangement, each binding having a toe portion and a heel portion.
  • the ski to which the invention relates can also be called monoski when using the terminology customary in waterskiing, since the skier when using a ski according to the invention, stands on a single skid
  • ski or monoski of the kind referred to above has become known which comprises a rigid supporting plate to which the ski bindings including toe and heel portions are screwed. Skiing with this known ski, however, has shown certain aspects which prejudice the running performance.
  • the known monoski is substantially rigid in its middle section which carries the supporting plate of the ski binding, and this rigid section is followed in front SUMMARY OF THE INVENTION
  • the invention resides in the novel construction of a monoski in which the components supporting the toe and heel portions of the ski binding are so formed that the ski body portion provided with the gliding surface practically does not present any rigid section.
  • the invention consists in a ski having a single ski body member formed with a gliding surface, two ski bindings mounted on said body member in side by side arrangement, each binding having a toe portion and'a heel portion, wherein the improvement comprises a support for the toe portion, a support for the heel portion, said two supports being fixed one behind the other in longitudinally spaced relation on said ski body.
  • ski-boot supporting surface on the toe and heel portions of the binding at a distance above the ski body member corresponding substantially to the width of the ski.
  • the ski body member provided with the gliding surface may be formed by a conventional ski, i.e., having a width from 7 to 10 centimeters and a length of about 210 centimeters when the ski is destined to be used by a person of about centimeters height, though it may be convenient that the most ideal length of this ski is somewhat longer than that of a conventional ski.
  • the length of the ski according to the invention may be from 215 to 220 centimeters.
  • the ski according to the invention is not suitable for stepping or walking, but it is destined particularly for running downhill. However, for moving overflat ground, the skier can use the conventional ski-poles, since the frictional resistance against gliding of the ski according to the invention is smaller than with a pair of conventional skis.
  • FIG. 1 is a perspective view of a ski according to the invention.
  • FIG. 2 is a transverse section of the central portion of the ski in FIG. 1 along the line II-II.
  • FIG. 3 is a view in elevation of the middle portion of a ski of FIG. 1, a ski-boot being attached to the binding at the right side, as seen in the direction of movement of the ski.
  • FIGS. 4 and 5 show in a manner similar to FIGS. 2 and 3 a transverse section and a view in elevation of a modification of the ski according to the invention.
  • FIG. 6 is a view in elevation of a further modification showing how a conventional ski can be transformed into a ski according to the invention.
  • FIG. 1 represents a ski 10 consisting of a single ski body member forming the skid or runner 11 provided with a gliding surface and having approximately the shape of a conventional ski.
  • the ski 10 has mounted thereon two bindings l2 and 13, disposed side by side.
  • Each of the bindings 12 or 13 is provided with a jaw portion 14 and 16, respectively, and with a heel portion 15 and 17, respectively which, in the represented example are shown as being safety cheeks and automatic heel release devices.
  • the two jaw portions 14 and 16 are fixed to a front support 18 and the two heel portions 15 and 17 are fixed to a rear support 19.
  • the binding supports 18 and 19 each comprise a carrier plate 20 and 21, respectively, situated in a same plane and forming the supporting surface of the sole of aski-boot30 (FIG. 3).
  • the carrier plates 20 and 21 are supported by a web 22 or 23, respectively fixed to the respective carrier plate or formed integral therewith as a section of a double-T beam extending in a plane at right angles to the ski surface and parallel to its longitudinal axis.
  • the lower flanges 24 and 25, respectively, of the double-T sections are secured to the ski body portion 11 by means of a pair of screws 26 and 27 (FIG.2) or 28, respectively (FIG.3).
  • the two supports 18,- 19 accordingly have the profile of a double-T of which the carrier plate 20 or 21 forms the larger flange.
  • the supports (FIG. 2) are assembled from semi-finished material available in commerce, i.e., from plates and profiles, for example by welding or rivetting; the supports also could be formed as integral molded parts, for example cast from a light-weight alloy.
  • rier plates 20 and 21 above the ski body portion 11 approximately corresponds to the width of the body portion 11, this width being 0.5 to 1 times the distance between the longitudinal center lines of the two bindings .12, 13.
  • the fixing of the flanges 24, 25 of the supports 18, 19 can be effected by the intermediary of a layer of resiliently yielding rubber or foam rubber 29 of a thickness of a few millimeters.
  • FIG. 6 represents a modification which forms a transitory stage which may be used by a person desiring sometimes to use two conventional skis for skiing and other times to use a single ski only.
  • the ski-binding comprises the check portions 14, 16 and the heel portions 15, 17,
  • ski-b00630 be attached at the front to the carrier plate 20 and at the rear to the carrier plate 21.
  • the carrier plates 20, 21 are supported by the webs 22 and 23, and the flanges 24 and 25,1
  • the supports 18 and 19 are not directly secured to the skid 11'., but by means of rivets 35, 36 are mounted on a base plate 37 made of a resiliently flexible material. This material may be a synthetic plastics material versely to the longitudinal axis of the skid l1
  • the base plate37 is provided at its front end, approximately in the longitudinal centralplane of the supports 18 and 19, with an upwardly projecting portion 38 and.
  • the base plate 37 in turn is clamped to the skid 11' by means of a ski binding having a safety jaw 40 and an automatic heel engaging device'41, these means being S secured to the skid 11 in conventional manner.
  • any conventional ski binding may be secured to the skid, for example a binding having lateral sole engaging jaws and a heel engaging cable with a tensioning device.
  • the particular advantage of the modification according to FIG. 6 is that the attachment of the supports 18 and 19 on the ski is releasable, the attaching means f being the same which serve to attach the ski-boot on a conventional ski.
  • a skier thus has the possibility, with a single pair of skis, to choose whether he will ski with a sole ski or with a pair of skis.
  • the supports 18 and 19 can be considered as an emergency means which enables an experienced skier, when a ski is broken, to continue a down hill run on a sole ski which would be easier than to use a substitute ski point which may be used only when the front portion of the ski is broken but not the middle portion adjacent to the binding.
  • a ski having a ski body member formed with a gliding surface, two ski bindingsfixed on said body member in side by side arrangem'ent,'each binding hav. ing a toe portion and a heel portion, wherein the improvement comprises a platform support for said toe 2.
  • a ski according to claim 1 in which said supports are fixed to the ski body member by means situated on a line extending transversely to the longitudinal axis of the body member.
  • a ski having a ski body member formed with a gliding surface, two ski bindings fixed on said body member in side by side arrangement, each binding having a toe portion and a heel portion, wherein the improvement comprises a support for said toe portion, and a support for said heel portion, said two supports being fixed one behind the other in longitudinally spaced relation on said ski body member, both said supports comprising a double-T profile having a larger flange and a narrower flange, said toe portions being mounted on the larger flange of one of said supports and said heel portions being mounted on the larger flange of the other support, and the narrower flange of both said supports being secured to said ski body member.
  • a ski according to claim 4 in which a layer of resiliently yielding material is arranged between the ski body member and said narrower flanges of the toe and heel portion supports.
  • each of said supports is formed as a solid web body.
