Definitions

  • the present invention relates to the technical sector of ski bindings, in particular bindings for Alpine skiing.
  • the invention relates to a ski stop device, destined to be mounted on the ski in a position adjacent to a binding for Alpine skiing, in particular in a forward position to a heel-piece for hooking the rear part of the ski boot to block the ski.
  • ski-stoppers i.e. ski stop devices which are mounted on the ski adjacent to a binding, for example a heel-piece.
  • the ski stop devices comprise a fixing element to the ski, which is fixed to the ski so as to be adjacent to the heel-piece, in a forward position in relation thereto, and a braking element which is conformed as a two-arm lever, where a first arm of the lever is in the form of a fork having a pair of arms distanced from one another by a greater distance than the width of the ski, and a second arm of the lever is conformed so as to have a pair of prongs substantially parallel to one another and at a prefixed reciprocal distance.
  • the braking element is preferably in a single body, with the two arms that are in a single body with the pair of prongs, for example, in particular, the braking element is formed by a metal rod bent and conformed so as to have, on one side (forming the first arm of the lever arm) the pair of arms, and on the other side (which forms the second arm of the lever) the pair of prongs, and a central part, for connecting the arms and the prongs, which is coupled to the fixing element.
  • the braking element is hinged (in an intermediate part between the pair of arms and the pair of prongs) to the fixing element so as to be oscillating about a hinge axis transversal to the fixing element and thus transversal to the ski so as to be able to assume at least two distinct configurations:
  • Stop devices usually comprise a sort of plate which is coupled to the pair of prongs, to form an abutment for the sole of the rear part of the ski boot.
  • the stop devices are conceived and predisposed in such a way that the braking element is always active, i.e. is forced to be kept in the operating configuration, with the arms of the fork kept lowered with respect to the ski and the pair of prongs, and therefore the plate, kept raised with respect to the ski.
  • the stop device kept in the operating configuration with the arms of the forks lowered, provides a braking action.
  • the ski boot When the skier hooks the ski boot to the ski, by lowering the rear part of the ski boot against the ski to hook it to the heel-piece, the ski boot pushes the plate downwards, and thus also push the pair of prongs downwards, causing the braking element to rotate about the hinge axis thereof to the fixing element, consequently raising the arms of the fork above the ski.
  • Some stop devices of known type include the use of springs to maintain the pair of prongs (or the plate) raised from the ski, and thus maintain the braking element in the operating configuration.
  • springs When the rear part of the ski boot is lowered onto the ski to hook to the heel-piece, the plate is pushed downwards to compress the springs; when the ski boot is unhooked from the heel-piece, the springs will push the plate upwards to return the braking element into the operating configuration.
  • stop devices of known type comprise a pair of recesses realised in the fixing element, having a shape such as to accommodate internally thereof the pair of prongs and a pair of guide walls, which are arranged below the recesses, to guide the prongs towards the ski, forcing them to near one another.
  • the plate When the ski boot is lowered onto the ski to hook to the heel-piece, the plate is pushed downwards, forcing the pair of prongs to exit the recesses and go into contact with the pair of guide walls, the shape of which guides the prongs towards the ski and forces the prongs to near one another; when the ski boot is unhooked from the heel-piece, the prongs will tend to return to the original reciprocal distance and will rise with respect to the guide walls, to return internally of the recesses, thus bringing the braking element into the operating configuration.
  • the pair of prongs acts as a sort of spring.
  • the skier in order to move upwards while wearing the skis, the skier keeps only the forward part of the ski boot hooked to the forward binding, i.e. the toe-piece, while the rear part of the ski boot is unhooked from the heel-piece.
  • the skier can simulate a walking step, as the ski boot can be oscillated with respect to the ski, in particular by raising the rear part of the ski boot.
  • Some of the specifications at present used for maintaining the stop device deactivated i.e. maintaining the braking element in the non-operating configuration when the skier desires to move uphill with the skis still attached, and thus after having unhooked the rear part of the ski boot from the heel-piece, consist in the use of locking elements which are activatable to abut the plate, or the pairs of prongs, and keep the plate, or the pairs of prongs, lowered with respect to the ski and therefore the arms of the fork raised with respect to the ski.
  • These blocking devices are, for example, constituted by levers or plates, hinged to the fixing element of the stop device, or to other elements fixed to the ski, and subjected to the action of the springs.
  • a further specification at present used to deactivate the stop device, and thus maintain the braking element in the non-operating configuration when the skier desires to cross uphill stretches with the skis attached to his/her feet, consists in using the same heel-piece to block and keep the plate or the prongs lowered towards the ski.
  • the plate, or the prongs must be pushed towards the ski and the heel-piece must be rotated about a vertical axis to the ski so as to bring an appendage thereof, or another abutment element, above the plate, to block it in the lowered position towards the ski and maintain the arms of the fork raised with respect to the ski, and thus maintain the braking element in the non-operating position by deactivating the stop device.
  • the aim of the present invention is therefore to provide a ski stop device that obviates the drawbacks in the prior art as described in the foregoing.
  • an aim of the present invention is to provide a ski stop device able to deactivate the braking element, i.e. maintain it in the non-operating configuration, in simple and rapid ways, without requiring rotation of the heel-piece and without having volumes such as to constitute lifting the ski boot.
  • ski stop device according to claim 1.
  • Other characteristics of the ski stop device of the present invention are set down in the dependent claims.
  • reference numeral (D) denotes the ski stop device provided by the present invention, in its entirety.
  • the stop device (D) comprises a fixing element (1) to the ski which is conformed and predisposed to be fixed to a ski in a forward position with respect to a heel-piece (T) suitable for hooking the rear part (PS) of a ski boot when the rear part of the ski boot is lowered towards the ski.
  • ski is not illustrated, while in figures 3 and 7 the fixing element (1) of the stop device (D) can be seen, predisposed forward of a heel-piece (T) for hooking a rear part (PS) of a ski boot (ski boot not illustrated in its entirety but only the rear part thereof).
  • the stop device (D) further comprises a braking element (2) having a shape that is such as to comprise a fork-shaped first part (21) conformed substantially as a fork having a pair of arms (22, 23) distanced from one another by a distance that is greater than the width of the ski and a second part (24) comprising a pair of prongs (25, 26) arranged substantially parallel to one another at a prefixed reciprocal distance.
  • a braking element (2) having a shape that is such as to comprise a fork-shaped first part (21) conformed substantially as a fork having a pair of arms (22, 23) distanced from one another by a distance that is greater than the width of the ski and a second part (24) comprising a pair of prongs (25, 26) arranged substantially parallel to one another at a prefixed reciprocal distance.
  • the braking element (2) is hinged to the fixing element (1) at a third part (27) that is intermediate between the first part (21) and the second part (24) (see for example figure 6 ) so as to be oscillating about a hinge axis that is transversal to the fixing element (1) and thus transversal to the ski.
  • the braking element (1) is preferably a single body, with the two arms (22, 23) of the fork in a single body with the pair of prongs (25, 26), for example, in particular, the braking element (2) is formed by a metal rod appropriately bent and conformed so as to have, on the one side, the fork with the pair of arms and, on the other side the pair of prongs, and an intermediate central part between the arms and the prongs which is coupled to the fixing element according to a transversal axis.
  • the stop device can also comprise, for example, a sort of plate (8) which is coupled to the pair of prongs (25, 26), to form an abutment for the sole of the rear part (PS) of the ski boot.
  • a sort of plate (8) which is coupled to the pair of prongs (25, 26), to form an abutment for the sole of the rear part (PS) of the ski boot.
  • the braking element (2) can assume at least two distinct configurations with respect to the fixing element (1), and thus with respect to the ski:
  • the fixing element (1) is conformed in such a way as to comprise a pair of recesses (31, 32) which are positioned and conformed for receiving internally thereof the pair of prongs (25, 26) so as to maintain the braking element (2) in the operating configuration (O), the pair of prongs (25, 26) being raised with respect to the ski and the arms (22, 23) of the fork being arranged at the sides of the ski and in a lowered position with respect to the ski (see for example figures 4 and 5 ).
  • the fixing element (1) is also conformed in such a way as to comprise a pair of fixed guide walls (41, 42) arranged and conformed in such a way as to guide the pair of prongs (25, 26) towards the ski and force them to near one another when the prongs (25, 26) are pushed out of the recesses (31, 32) and pushed towards the ski as a consequence of the lowering of the rear part (PS) of the ski boot towards the ski for hooking thereof with the heel-piece (T), with a consequent raising of the arms (22, 23) of the fork and positioning of the braking element (2) in the non-operating configuration (I) (see for example figures 5 , 10 and 11 ).
  • the prongs elastically deform to near one another, sliding along the fixed guide walls towards the ski by a pushing action towards the ski, exerted thereon by the ski boot.
  • the particularities of the stop device (D) of the present invention consist in the fact that the fixing element (1) is also conformed so as to comprise a pair of cavities (51, 52), inferiorly of the pair of fixed walls (41, 42) (visible for example in detail in figures 6A , 10 , 11A , 13 , 14 , 15A e 15B ), and in that it comprises means for keeping closed and for opening the cavities (51, 52).
  • the means (M) for keeping closed and for opening the cavities (51, 52) are predisposed and conformed in such a way as to be arranged with respect to the fixing element (1) in two distinct configurations:
  • the means (M) for keeping closed and for opening the cavities (51, 52) are usually maintained in the first configuration (M1), in which they close the cavities (51, 52) so that the stop device (D) can be normally used, i.e. constantly active, with the braking element in the operating configuration, and, when the skier lowers the ski boot to hook the rear part to the heel-piece, can be brought into the non-operating configuration.
  • the braking element can return autonomously and without problems into the operating configuration to reactivate the stop device, in the above-described ways.
  • the stop device can be deactivated in a simple and rapid way by predisposing the means (M) for keeping closed and for opening the cavities in the second configuration (M2) with the cavities (51, 52) open.
  • the skier by pushing the prongs (25, 26) downwards (or pushing the plate (8) downwards), i.e. towards the ski, the skier, for example using the ski stick, or even by hand, can force the prongs (25, 26) to exit the recesses (31, 32); and by pushing the prongs (25, 26) even further downwards, the prongs (25, 26) will be forced to near one another by sliding along the fixed walls (41, 42), with a contemporaneous raising of the arms (22, 23) of the fork into a raised position from the ski.
  • the prongs (25, 26) will not be able to freely and spontaneously rise towards the recesses (31, 32) and thus they will be maintained in a lowered position towards the ski, with the consequent maintaining thereof in a raised position with respect to the ski of the arms (22, 23) of the fork, and thus with the consequent maintaining of the braking element (2) in the non-operating configuration (I).
  • the skier can freely maintain the rear part of the ski boot unhooked from the heel-piece and can cover uphill stretches with the skis fastened to the feet with no problems between the ski boot and the ski, as the stop element will constantly and in all cases be maintained in a deactivated status.
  • the stop device (D) can be easily and rapidly deactivated, i.e. the braking element placed in the non-operating configuration (I), without any need to have recourse, as in the prior-art cases, to the use of external locking organs, such as levers or plates, or to the rotation of the heel-piece.
  • the prongs will return to the mutual prefixed distance by rising along the fixed guide walls (41, 42) up to reinserting in the relative recesses (31, 32).
  • ski stop device (D) of the present invention are set down in the following.
  • the means (M) for keeping closed and for opening the cavities (51, 52) can be conceived in such a way as to comprise a pair of movable walls (61, 62) which are predisposed so as to be movable with respect to the fixing element (1) in such a way as to be positionable with respect to the pair of fixed walls (41, 42) in at least two positions:
  • the stop device (D) can advantageously comprise, in the preferred embodiments illustrated in the appended figures, a slide (6) which is coupled to the fixing element (1) in such a way as to be translatable transversally to the fixing element (1), and thus transversally to the ski, the pair of movable walls (61, 62) being predisposed on the, and borne by, the slide (6).
  • the slide (6) is translatable with respect to the fixing element (1) at least between two lateral positions, a first lateral position (L1) in which the movable walls (61, 62) are positioned in the aligned position (A) with the fixed walls (41, 42) (see figures 4 , 5 , 6A , 10 , 11A ) and a second lateral position (L2) in which the movable walls (61, 62) are positioned in the de-aligned position (B) with respect to the fixed walls (41, 42) (see figures 12, 13 , 14 , 15A ).
  • FIGS 6A, 11A , 15A and 15B instead, illustrate, as mentioned in the foregoing, a possible interesting embodiment of the stop device (D) of the invention.
  • the means (M) for keeping closed and for opening the cavities (51, 52) can comprise a spring (9) which is predisposed in a housing (90) realised in the fixing element (1).
  • the housing (90) is realised in the fixing element (1) and the spring (9) is predisposed in the housing (90) in such a way that the spring (9) is in contact with the slide (6) and maintains the slide (6) in the first lateral position (L1), so that the movable walls (61, 62) are normally maintained in the aligned position (A) thereof with the fixed guide walls (41, 42) (see for example figures 6A and 11A ).
  • the stop device (D) can be normally used, i.e. be constantly active, with the braking element in the operating configuration ( figure 6A ), and, when the skier (2) lowers the ski boot to hook the rear part to the heel-piece, can be brought into the non-operating configuration (I) ( figure 11A ).
  • the braking element (2) can return autonomously and without problems into the operating configuration to reactivate the stop device, in the above-described ways.
  • the skier by pushing the prongs (25, 26) downwards (or by pushing the plate (8) downwards), i.e. towards the ski, for example by using the ski sticks, or even a hand, can force the prongs (25, 26) to exit the recesses (31, 32) and by pushing downwards even more, the prongs (25, 26) will be forced to near one another by sliding along the fixed walls (41, 42), with a contemporaneous raising of the arms (22, 23) of the fork into a raised position from the ski.
  • the skier can release the slide (6): the spring (9) will tend to push the slide (6) to return it towards the first lateral position (L1), but the presence of the prongs (25, 26) in the cavities (51, 52) will prevent translation thereof (see figure 15B ).
  • the prongs (25, 26) will be maintained in the cavities (51, 52) and will not freely and spontaneously rise towards the recesses (31, 32) and thus will be maintained in a lowered position towards the ski, with the consequent maintaining in a raised position with respect to the ski of the arms (22, 23) of the fork, and thus with the consequent maintaining of the braking element (2) in the non-operating configuration.
  • the skier can freely maintain the rear part of the ski boot unhooked from the heel-piece and can cover uphill stretches with the skis fastened to the feet with no problems between the ski boot and the ski, as the stop element will constantly and in all cases be maintained in a deactivated status.
  • the stop device can be reactivated, and thus returned to the normal functioning thereof, automatically due to the presence of the spring (9).
  • the prongs (25, 26) will return to the mutual prefixed distance by rising along the fixed guide walls (41, 42) up to reinserting in the relative recesses (31, 32) and at the same time the spring (9) will push on the slide (6) to as to return the slide (6) automatically into the first lateral position (L1) of alignment (A) of the movable walls (61, 62) with the fixed walls (41, 42) ( figures 6A e 11A ).
  • the fixed walls (41, 42) can preferably be realised and conformed in such a way as to have a mutually converging conformation towards the ski or have a conformation that is such as to be mutually parallel and at a reciprocal distance that is smaller than the prefixed reciprocal distance of the prongs (25, 26) of the braking element (2).
  • the movable walls (61, 62) can be realised and conformed in such a way as to have a mutually converging conformation towards the ski, with the same inclination as the fixed walls (41, 42) or with a different inclination but however with a reciprocal distance that is smaller than the prefixed reciprocal distance of the prongs (25, 26) of the braking element (2).
  • the movable walls can be realised and conformed such as to have a conformation such as to be parallel to one another and at a reciprocal distance that is smaller than the prefixed reciprocal distance of the prongs (25, 26) of the braking element (2).
