Definitions
- the invention relates to an improvement made to cross-country ski boots. It also relates to an assembly for the practice of cross-country skiing comprising such a boot and a ski provided with a binding.
- low shoes are generally used, the sole of which is flexible, and the upper of which, possibly integral with the sole, has an external buttress.
- the sole In order to allow maximum travel of the boot relative to the ski in order to obtain optimum thrust and amplitude of stride, the sole must be flexible and be articulated under the toe of the boot, on the upper face of the ski skate.
- the advantage of having a flexible sole lies in the fact that it accentuates this thrust.
- the articulation and the fixing of the front of the sole on the ski skate are carried out around an axis transverse to the longitudinal axis of the sole, which advantageously coincides with the axis d balance of the ski, also sometimes called the axis of rotation. This is generally arranged, according to the standards, under the toe of the sole, either just in front of the toes, or just behind and below the toes, to benefit more effectively from the movements, and the impulses, and to ensure a better ski guide.
- the soles of these cross-country ski boots have either a relatively wide central groove or two lateral grooves, all longitudinal, intended to cooperate with a respectively central projection or two lateral projections, in order to allow better guiding the ski or a better grip of the boot on the ski, in particular during the descent or sliding phases of the two skis simultaneously
- the projections cooperate with the corresponding grooves, and avoid untimely twisting of the boot, twisting rendered so much easier that the sole is flexible, and the risks of fracture likely to arise from it.
- this projection-groove or projection-slot system is sufficient for experienced skiers, on the other hand, it generally appears to be insufficient for beginners or average skiers, as soon as a slope, even of a limited gradient, presents itself.
- Systems have been proposed for attaching the boot back to the ski, in order to secure it to the ski during descents. However, these systems require the installation of a fixing in the rear position. In addition, they induce the provision of a groove behind the heel of the shoe, in order to allow cooperation with the rear binding. Now, more and more, it is sought in cross-country skiing, to produce shoes which are as close as possible to walking shoes.
- a shoe-binding assembly has been described for the practice of cross-country skiing also allowing the practice of off-piste skiing, that is to say ski touring.
- This assembly comprises a beam articulated on the ski provided with two anchoring means on the sole of the boot. These means are arranged respectively the first at the front of the shoe, the second at the level of the front of the toe (see in particular Figure 6).
- This arrangement which calls for an additional part called “beam”, is favorable for the practice of ski touring and cross-country skiing in alternative steps.
- the sole has three parallel longitudinal grooves having at their front ends hinge means of the type in question, intended to cooperate with complementary means of attachment to the top of the ski.
- the two outer grooves each receive an axis arranged in the extension of one another, thus forming a single axis of articulation.
- the central groove has an axis slightly set back relative to these two axes.
- the rear axis and the imaginary axis corresponding to the two axes of the lateral grooves authorizes two positions for the practice of skiing, namely the first for the practice of the alternative step, the second, where the boot is firmly fixed on the ski, in particular for the practice of descent, while ensuring good lateral hold thanks to the plurality of parallel grooves.
- This arrangement cannot be envisaged on current cross-country skis, in particular for the practice of skating, due to the narrowness of these skis.
- the invention overcomes these various drawbacks. It relates to a cross-country ski boot, more particularly intended for practice according to the so-called alternative pitch technique, capable of having sufficient travel of the sole relative to the ski during the phases of progression according to the alternate pitch, but also capable of temporarily securing the sole to the ski, especially during the descent phases. Description of the Invention
- This cross-country ski boot consisting of a rod secured to a sole and the sole of which has a means of attachment and articulation on the upper face of the skate of a ski, means located in the vicinity of the front end of the sole, is characterized in that the underside of the sole also includes a second fixing means, arranged in the zone between the heel and the metatarsophalangeal joint, able to cooperate with an additional fixing means arranged on the upper face of the ski skate.
- the invention consists in temporarily securing the sole to the ski, so as to prohibit the movement of the boot relative to the binding of the ski, and therefore, to allow easier control of the ski by the skier. , especially during the descent phases, the technique then approaches traditional alpine skiing.
- this second fixing means is located just below the anterior limit of the arch of the foot.
- the flexible sole has a notched, attached underside, made of rubber.
- the invention also relates to an assembly for skiing using this boot, comprising a ski and a binding, integrated or not integrated into the ski, binding comprising:
- a member capable of cooperating and of retaining the first means of fixing the boot, capable of sliding in a direction parallel to the longitudinal direction of the ski,
- control means disposed at the front of the binding, intended to slide said member to engage or disengage it from the first means of fixing the shoe.
- This assembly is characterized in that the binding comprises a second member, intended to cooperate and to retain the second means of fixing the sole of the shoe disposed between the heel area and the metatarsophalangeal joint.
- these two members are constituted by hooks open towards the front of the ski, these hooks being actuated by the binding control means, only the first hook being engaged in the first binding means of the boot during the practice of the alternative step for the progression in slope or on the flat, while the two hooks are respectively engaged in the first and the second means of fixing of the shoe for the progression in particular in descent.
- control lever has a cursor that can be actuated with the skier's stick, a cursor intended to effect the engagement of the second hook at the level of the second fastening means of the boot, while the first is already engaged in the first fastening means of the shoe.
- the second hook is open in the direction of the front of the ski, and its free end is inclined upwards, and typically has an inclination of 45 degrees relative to the horizontal.
- the invention therefore differs from the state of the art cited in the preamble by the fact that the second attachment and articulation means is disposed between the metatarsophalangeal joint and the heel, and this to cooperate with a second complementary means arranged on the upper face of the ski runner, actuable separately from the first additional fixing means.
- This provision thus allows the practice of skiing, in particular in alternative pitch, thanks to the flexibility of the boot and also authorizes during descents, a firm blocking of the rear part of the foot, which secures beginner skiers.
- it is possible to reconcile two contradictory provisions, namely a flexible sole for practicing alternative pitch and a sole rigidly fixed to the ski desirable during descents. Description of the figures
- Figure 1 is a summary perspective view seen from three quarters below a cross-country ski boot according to the invention.
- FIGS 2 and 3 show the ski boot seen from below, in accordance with the invention.
- Figure 4 is a schematic side representation of an assembly for skiing in accordance with the invention.
- Figures 5 and 6 are schematic representations in longitudinal section of a binding of the Prior Art, as marketed by the Applicant, for the practice of cross-country skiing according to the technique of alternative pitch, respectively in the open position ( Figure 5 ), and in the locked position ( Figure 6).
- Figures 7 to 9 are figures similar to Figures 5 and 6, of a binding according to the invention, shown respectively in the open position (Figure 7), in the partially locked position ( Figure 8) for the actual progression according to the technique of the alternate step, and finally, in the fully locked position (Figure 9), for progression, especially when going downhill.
- FIG. 10 represents a detailed schematic view of the front part of the binding according to the invention. Ways of Realizing the Invention
- the cross-country ski boot shown in FIG. 1 essentially comprises a rod (1), open on the front so as to be able to allow the introduction of the foot through the opening (2).
- a flap (3) covers the laces and the other closure means.
- the sole (5) has a transverse axis of fixing and articulation (8), intended to cooperate with a complementary fixing means secured to the upper face of the ski skate.
- this shoe comprises, in a co-linear manner with respect to the articulation axis (8), a second fastening means, also constituted by a transverse axis (9), parallel to the first axis (8), and arranged at the level of the arch of the foot, in particular directly above its anterior zone.
- This second axis (9) is intended to cooperate with additional complementary means, arranged on the upper face of the ski skate, aligned with said first means and intended to cooperate with this transverse axis (9).
- these two characteristic articulation axes (8, 9) are each arranged in an unreferenced cavity, provided for this purpose, distinct from each other, provided on the outer face of the sole (5).
- the anterior binding axis ( 8) is secured to the binding provided on the ski skid, in a traditional and known manner.
- the skier engages the second fastening means coming to cooperate with the second transverse fastening axis (9), and therefore secures the entire sole to the shoe, preventing the movement of said sole. compared to the ski skate.
- the flexible sole has a notched underside attached with rubber, simply perforated to allow access to the cavities in which the two parallel transverse axes of fixing are arranged.
- the invention also relates to an assembly for the practice of cross-country skiing by means of such a boot.
- This set includes a ski, designated by the general reference (30), comprising a spatula (31), a central area called the skate (32), and a heel (33).
- a ski designated by the general reference (30)
- a spatula 31
- a central area called the skate
- a heel 33
- FIGS 5 and 6 show a binding of the prior art for the practice of cross-country skiing.
- This binding comprises a horizontal plate (11) fixed on the shoe (32), terminated by a hook (12) open towards the rear of the ski.
- This base plate for example made of metal, is fixed on top of the pad area (32) by screws or equivalent means not shown.
- the base (11) has two lateral vertical flanges (13) disposed on each side of the ski, at which the horizontal portion (14) of a connecting member (15) is articulated, the other horizontal portion of which (16) is articulated at the level of a lever-shaped control means (17).
- the two hooks (12) and (19) provide between them a gap capable of allowing the insertion at this level of the fixing and articulation axis (8) constituting the first shoe fastening means.
- this binding thus described further comprises a second horizontal plate (28), capable of sliding in the longitudinal direction of the ski.
- the first sliding plate (18) has a longitudinal lumen over its entire length, to allow the passage of said second plate (28).
- the front end (23) of this second sliding plate (28) is engaged in a slider (24) having on the top a press button (25).
- the cursor (24) is connected to the control lever (17) by means of a substantially horizontal light (27), in which the hinge pin (22) slides from the front end (21) of the first sliding plate ( 18) on the control lever (17).
- the rear end of the plate (28) takes the form of a hook (26), open towards the front of the ski.
- the two hooks (12) and (19) are, as already said, in abutment, so as to trap the axis (8) of articulation and fixing of the boot, disposed at the toe level.
- the second fastening axis (9) of the shoe advantageously located directly upstream of the arch of the foot, is free, that is to say can freely pass in front of the hook (26), held in position back behind this axis (9). In this way, the heel can be freely released to allow the movement of the skier relative to the ski.
- the distance between the two fixing axes (8) and (9) is of the order of eight to ten centimeters.
- the skier When the skier approaches a descent, and wishes to secure his boots in a fixed manner with the skis, he presses, for example using the end of his stick on the press button (25), possibly provided with a directed opening upward to facilitate its action, and this to bring the cursor (24) forward in the direction indicated by the arrow in Figure 9, by sliding the light (27) relative to the axis of articulation (22).
- the cursor (24) drives the anterior end (23) of the second sliding plate (28), and therefore brings the hook (26) above the second fixing axis (9) of the shoe arranged at the base of the upstream area of the arch of the foot, an axis which is thus trapped and immobilized.
- the free end (29) curved towards the front of the second hook (26) is inclined by 45 degrees relative to the horizontal, so as to optimize the safety conditions when using such a fixation. Indeed, in the event of a fall with blockage of the skier's foot, this inclined orientation allows the shock to release the second fastening axis (9) of the boot, and thus regain the safety of using a traditional binding.
