Definitions

  • the present invention mainly concerns an arrangement in a ski binding for fastening a skiing boot provided with a front sole extension which has a smaller width than the remaining sole, comprising a toe iron with an approximately plane mount­ing plate and a portion intended to support the sole extension, and a portion facing to the rear and intended to support the front portion of the wider sole portion, and with the front portion of said toe iron being provided with a means for hold­ing the toe extension, and with the portion of said mounting plate serving as a support of the sole extension being prov­ided with lateral portions that are bent up to serve as lateral supports of the sole extension.
  • the invention also relates to a skiing boot intended for use in connection with said ski binding.
  • ski bindings of the above kind only the sole extension facing forward is fastened to the ski. Any bending of the boot sole, thus, occurs in the forward area of the boot sole, in the last phase of kick off bending occurs quite in front, at or even in front of the toe area of the foot.
  • the object of such a binding is that the skier should achieve maximum length of step in kicking off. Utilization of such bindings is rendered possible by the very carefully prepared trails we find almost everywhere to day.
  • the ski boot receives hardly any lateral control by such a binding. This has a negative effect in case of down­hill running when a lateral force will act on the boot when the skier turns, said force urging the boot out relative to the ski. With the extremely light-weight boots used today this is a considerable disadvantage. Also when the skier goes upphill and has to put the skis at a certain angle relative to the trail direction (herring-bone) there will be lateral forces acting on the boot.
  • bindings have a very restricted extension in the longitudinal direction and, thus, essentially only support the sole extens­ion and, possibly, the foremost portion of the wider sole portion.
  • this is achieved by the aid of a ski binding of the kind mentioned above which is character­ized by the fact that the portion of the mounting plate that is intended for supporting the front portion of the wider part of the sole has a smaller width than that of the cooper­ating sole, and that the edges of said portion of the mount­ing plate are provided with bent up lateral edges with a small­er height than the thickness of the sole and intended for cooperation with grooves in the underside of the sole.
  • a preferred embodiment of the invention is characterized by the fact that each of the two lateral edges of the mounting plate follows a straight line, so that the bent-up lateral portions for supporting the edges of the sole extension form a straight extension of the bent-up lateral portions at the portion of the mounting plate that is extended rearwards. Further features of the binding will appear from dependent claims 3 and 4.
  • An arrangement in a skiing boot with a front sole extension which has a smaller width than the remaining sole, for use in connection with a ski binding og the kind mentioned above is characterized by the fact that the sole extension turns into a wider portion of the sole via steps on both sides of the sole, and that a groove is provided in the underside of the wider sole portion, starting from the inner corner of the steps/shoulders and extending rearwards.
  • Binding 1 in Figure 1 comprises a toe iron 1 with a plane mounting plate 2.
  • Mounting plate 2 is wider at its rear edge than at its front edge, and the lateral edges 3 and 4, thus diverge from the front to the rear.
  • Each of the lateral edges 3 and 4 are provided with bent-up edge portions 5 and 6.
  • the front portion 5′, and 6′, respectively, of said edge portions is intended as a lateral guide for the sole extension 7 of sole 8 of a skiing boot.
  • Said portions 5′, 6′ have the same or greater height than the thickness of extension 7.
  • the rear portions 9 and 10 of the bent-up lateral portions 5 and 6, respectively have less height than the bent-up portions 5′ and 6′, respectively, and they also have a smaller height h than thickness t of the boot sole (cf.
  • FIG. 3 Mounting plate 2 of toe iron 1 is provided with apertures for fasten­ing the toe iron to a ski 12.
  • pins 13 projecting upwards are provided to cooperate with and pass through corresponding apertures 14 in the sole extension 7 when in use.
  • a fastening means for the boot sole extension 7 is provided. Said fastening means is commonly known and, thus, does not form part of the invention.
  • Figure 1 it is shown as a simple clamping means comprising a threaded pin 15 which is fastened at the front portion 2′ of mounting plate 2.
  • a plate 16 with an aperture 17 is provided to be fitted onto pin 15 after a skiing boot with its sole extension 7 is insert­ed into the toe iron, so that pins 13 engage in apertures 14. Sole extension 7 is clamped to plate portion 2′ by the aid of plate 16 and a wing nut 18.
  • a fastening means comprises an angular lever 19 which is rotatable about an axle 20 which is firmly arranged in upwards extended lugs 21 of the lateral edges 5′.
  • the binding is shown in a position for use with the boot fastened in the binding, and the locking arm 19′ of lever 19 turned to an over centre position and clamping the boot sole. The pressure from the locking arm may, if desired, be distributed by a pressure plate not shown. Actuat­ing arm 19 ⁇ of lever 19 is pressed down towards the upper side of ski 12 and forms a sloping face which will prevent snow from collecting inside the binding.
  • the wider portion of the sole turns into the front sole extension 7 via steps 20, 21.
  • grooves or channels 23, 24 are provided in the underside of the sole to correspond to the cams or bent­up lateral edges 9, 10 of the toe plate.
  • the lateral guide will be efficient both for diagonal gait, i.e. when the ski is moved flat on a ski track, and for skating steps as well. Even if the boot is placed on edge, i.e. inclined relative to the surface of the ski, the boot will be in engagement with the inner cam or the raised portion 9 og 10 will be in inside groove 23 or 24 all the time.
  • the toe iron of the binding provides for good support to the wider portion of the sole, since the toe iron supports most of the surface of said wider portion all the way back to the ball of the foot.
  • the sole is prevented from sagging towards a narrow ski.
