Definitions

  • Subject of the invention is a binding for alpine cross-coun try skiing comprising a thin transversal spacer placed, al ⁇ most perpendicularly, between binding and ski to allow os- 5 cillation of said binding at a distance from the toe of the boot: practically corresponding to the phalange-metatarsus areartof physiological articulation of the foot and, in this way, achieve maximum thrust for the next upward step.
  • Said' spacer can be tilted up and down on its own hinge as 10. desired to allow the binding and the ski to lie closely to ⁇ gether for downward runs.
  • The- binding is connected to the ski by means of a flat, longitudinal spacer whose external front end is articula ⁇ ted on the front hinge of said binding, while its internal 15 back end articulates on a hinge placed at the summit, of the- transversal spacer. This latter articulates on a se ⁇ cond hinge, parallel to the first one, mounted on the ski.
  • the binding is connected 25 to the ski by means of a flat flexible longitudinal stay made of metal or other material, underneath the binding and passing above the transversal spacer, whose external front end articulates on the front hinge of said binding while the back end is fixed to the ski behind said trans_ 30 versal spacer.
  • a flat flexible longitudinal stay made of metal or other material, underneath the binding and passing above the transversal spacer, whose external front end articulates on the front hinge of said binding while the back end is fixed to the ski behind said trans_ 30 versal spacer.
  • the binding is connected by means of a front connecting rod to a support mounted on the ski.
  • This connecting rod is prevented from assuming an angle greater than that corresponding to maximum backwards os- cillation of the binding, practically coinciding with the binding's parallel alignment to the ski.
  • the connecting rod articulates internally by means of a fork mounted at the tip of the binding.
  • the transversal spacer articulates on a support mounted on the binding by screws or other means, and has at its extremity a roller, freely.-moving on a transversal axis, which constitutes the fulcrum point of binding oscilla ⁇ tion.
  • Said roller permits translation, caused by the force com ponent, practically parallel to the ski, of the end of the connecting rod articulated onto the binding.
  • the transversal spacer ar ⁇ ticulates on a support mounted on the ski and, like the extremity, it also has a freely moving roller on a trans_ versa! axis, which constitutes the fulcrum point of the binding's oscillation.
  • the transversal spacer is pre ⁇ ferably fixed in the perpendicular position between the binding and the ski, by means of an elastic fork whose central straight section forms the pin of the hinge fit ⁇ ted on the extremity of the spacer itself. The two ends of said fork are bent outwards and aligned so that they can be pressed into 1 two aligned eyelets in a strap fixed to the ski or to a supporting means fixed to the binding.
  • the spacer By detaching said ends of the fork from the eyelets, the spacer can then be tilted to the downward run position.
  • the central section of the fork can be used as a pin for the rollers included in the two last executions.
  • Fig.1 Side view of a boot fitted to the ski with usual bindings with the back foot making an upward step.
  • Fig.2 View of the ski binding, subject of the invention, showing the longitudinal spacer.
  • Fig.3 Ditto as above in the downward run position.
  • FIG.7 View of the ski binding, subject of the invention, showing the longitudinal flexible .stay.
  • Fig.8 View of the ski binding, subject of the invention, showing the front connecting piece.
  • Fig. 1 shows diagrammatically the mean position of the geometrical axis (51) of rotation of a boot (52) with the hind foot taking an upward step, when an ordinary binding (50) is mounted on the ski (54) by means of the strap(53).
  • Said axis (51) is fa (distance D) from the mean axis (55) of the zone corresponding to physiological articula ⁇ tion between phalanges and metatarsus .
  • Fig. 2 shows a binding (10) which, according to the pre ⁇ sent invention, has a front hinge (11) fixed by means of the strap (12) and screws (19) to the front end (32) of the longitudinal spacer (14).
  • the transversal spacer (16) is connected at its summit, by means of the hinge (18) with the longitudinal spacer
  • the pin for the hinge (18) consists of the central straight section (22) of the elastic fork (21) whose aligned ends (23) (24) bent outwards, fit into the eyelets (25) (26) of the strap (27) mounted by screws (28) on the ski.
  • the hook (3C) with a tongue (31) and groove (48) facing inwards is fixed to the ski by the screws (29) .
  • the locking device (40) is fixed at the back to the ski.
  • the double flexible stay (42) connects the binding,by means of the screw (43) » to the angular support (44) fixed to the ski by means of the screw (45) .
  • Fig. 7 illustrates a variation consisting in use of the
  • This stay made of metal or some other material, is held at its front end (62) to the strap (12) by means of the screws (58) and, curving round (63), passes over the spa ⁇ cer (59) connected, by means of the upper hinge (60),
  • Figures 8 and 9 show a variation consisting in oscillation by the binding (70) on the ski (88) being guided by means of the front connecting piece (71) and the roller (72) supported by the transverse spacer (73).
  • Front articulation (77) of the connecting piece is made by means of the small pins with spacers (79) anchored to the sides (78) of the C-shaped support (74) fixed to the ski with screws (75) .
  • Rotation of the connecting piece is limited by the end- stroke stops (80).
  • Back articulation (81) takes place by means of the small pins anchored in the fork (76) mounted at the tip of the binding (70).
  • This fork has short arms (85) at 90° turned inwards and supporting the aligned pins (86), but out of line with the axis of articulation (81).
  • the inner ends of the sides of support (74) are .cut in to form the teeth (87).
  • the distance between the extremity of said teeth and the front articulation is greater than the centre distance between said front articulation and the back articulation of said connecting section, but lesser than said centre distance increased by the misalignment of the pins (86) .
  • the spacer (73) is mounted on the binding (70) by means of the C-shaped support (90), with articulation (91) on the small pins anchored to the sides (92).
  • the spacer. (73) supports, by means of the eyelets (93) the central section (98) of the elastic fork (94), structure and operation of which are substan ⁇ tially the same as those of the fork (21) in Figs. 2 and 3, and on which the roller (72) is fitted.
  • the screws (97) can be screwed into any one of a series ..of holes in the binding aligned longitudinally, to allow : the position of the spacer on the binding to be adjusted and. consequently adjustment of the fulcrum point of os ⁇ cillation on the ski (88) according to the size of the skie *s foot. Operation Operation is practically the same as described above for the other types.

Abstract

La fixation (70) ci-décrite pour ski de fond alpin oscille sur le ski (88) au moyen d'un élément d'espacement mince transversal disposé à une certaine distance de la pointe de la chaussure (47) correspondant pratiquement à la zone d'articulation physiologique des phalanges et du métatarse du pied pour obtenir une poussée maximum exercée par le pied pendant que l'on monte une pente. L'agencement permet de faire basculer l'élément d'espacement (73) pour que la fixation (70) adhère étroitement au ski (88) lorsque le skieur descend une pente.
