Definitions

• the invention relates to an improvement to cross-country ski boots; it also relates to an assembly for skiing, comprising a ski, a binding and this characteristic shoe.
• each ski is launched alternately forward in two parallel rails provided for this purpose in the track.
• the sole of which is flexible and, where appropriate, the upper secured to the sole has an external buttress. It is essential that the sole is flexible and is articulated under the tip of the boot on the upper face of the ski skate, to allow the maximum clearance of the boot relative to the ski to obtain maximum thrust and amplitude of stride. It is also important that the sole is flexible to accentuate this push.
• the upper always attached to the sole, includes a semi-rigid collar hugging the bottom of the tibia articulated on a rigid buttress placed at the malleoli to allow a transfer of the impulses and the push towards the ski.
• a semi-rigid collar hugging the bottom of the tibia articulated on a rigid buttress placed at the malleoli to allow a transfer of the impulses and the push towards the ski.
• the articulation and the fixing of the front of the sole to the ski skate is carried out around an axis transverse to the longitudinal axis of the sole, which coincides with the '' axis of balance of the ski, axis also sometimes called axis of rotation, arranged, according to the standards, under the tip either just in front of the toes, or just behind and below the toes to benefit more effectively from movements, impulses and to ensure better guidance of the ski.
• the invention overcomes these drawbacks. It relates to a cross-country ski boot which is capable of being used for one or the other of these two techniques, while preserving the specific needs of each, namely the low travel of the sole with respect to skiing in the skater's technique, and on the contrary authorizing a large amplitude of this sole with respect to the ski for the practice of the alternative step, while authorizing an ideal center of thrust for the practice of the skater's step.
• This cross-country ski boot consists 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 located at the front end of the sole at in the vicinity of the toes, is characterized in that the underside of the sole also includes a second fastening means disposed in the vicinity of the metatarsophalangeal joint, able to cooperate with a complementary fastening means disposed on the upper face of the ski runner.
• the invention is characterized by the fact that the lower external face of the sole of the boot comprises two fixing means on the upper face of the ski skate, the first disposed in a known manner in front of the sole at the toes, the second at the metatarsophalangeal joint.
• the second means arranged at the level of the metatarsophalangeal joint is engaged on a complementary means provided for this purpose on the upper face of the ski skate, but slightly behind the first traditional means of fixation.
• the characteristic shoe of the invention can be used with a special binding for the practice of skating which is essentially characterized by the presence of a metatarsophalangeal connection.
• the metatarsophalangeal joint is located at the junction of the metatarsals and the phalanges proper.
• the sole which is flexible, presents a limited possibility of movement relative to the ski by forming a small angle between this joint and the heel, while the surface between the first and second fixing means form a bearing surface which determines a thrust zone allowing a more effective impulse.
• the invention makes it possible to practice either the skater's step or the skating step with a flexible sole and no longer necessarily rigid, as is currently the case for skating.
• the shoe according to the invention differs from that described in document FR-A-2 595 951 cited in the preamble, by the fact that it uses two fastening means arranged respectively, the first at the toes, the second at the level of the metatarsophalangeal joint which can be coupled or not, and no longer with a single attachment formed by a rear stud disposed at the metatarsophalangeal level associated with a front stop. It is therefore a different architecture fulfilling different functions, for different results (either no skater or skating for the invention and no longer only skating for this document).
• the invention also relates to an assembly for skiing, using this boot, assembly comprising a ski and a binding, integrated or not integrated into the ski, binding of the type comprising:
• a member capable of cooperating and retaining the first means of fixing the boot, sliding in a plane parallel to the plane of the upper face of the ski, .
• control means disposed at the front of the attachment, intended to slide said member until it engages in the first attachment means.
• This attachment is characterized in that it comprises a second member capable of cooperating and of retaining the second attachment means disposed in the vicinity of the metatarsophalangeal joint.
• the two members cooperating with the two characteristic means for fixing the sole of the shoe are formed by hooks open towards the front, these two hooks being actuated by the lever for controlling the binding, the first hook during of the practice of the alternative step, the two hooks engaged together during the practice of the skater's step.
• these two hooks are both open towards the front, or even both towards the rear, they can also be opposite, namely one open towards the front, the other towards the rear or vice versa.
• control lever has a cursor that can be actuated with the skier's stick, intended to engage the second hook while the first is already engaged.
• Figure 1 is a summary perspective view seen three quarters below a ski boot according to the invention.
• Figures 2 to 5 show other embodiments of the invention.
• Figure 6 is a schematic representation of an assembly for the practice of skiing according to the invention.
• Figures 7 and 8 are schematic sectional representations of a conventional binding marketed by the Applicant, for the practice of cross-country skiing according to the alternative pitch, respectively in the open position ( Figure 7) and in the locked position ( Figure 8).

• Figure 12 is an enlarged view of the front part of a binding according to the invention.
• the ski boot shown in FIG. 1 essentially comprises a rod (1), open on the front so as to be able to introduce the foot into the opening (2).
• a flap (3) covers the laces and the other closure means.
• the upper (1) is integral with a sole (5) whose lower external face (6) has one or two guide slot (s) (7) disposed in the longitudinal axis of the shoe from the toe (8) to the heel (9).
• the tip (8) of the sole comprises at the toes a transverse axis (10) for fixing and articulation, intended to cooperate with an additional fixing means fixed on the upper face of the ski skate.
• this shoe comprises in the same transverse slot (7), a second fastening means constituted by a transverse axis (11) parallel to the first axis (10), disposed at the level of the metatarsophalangeal joint. .
• This second axis (11) is intended to cooperate with additional complementary means disposed on the upper face of the ski runner, slightly behind the first fixing means which cooperates with the transverse axis (10).
• the skier When the skier wishes to practice the alternative step, it suffices to engage the first transverse axis (10) located furthest forward, generally just in front of or at the level of the toes, in the complementary fixing means provided for this purpose on the top. of the ski skate.
• the appropriate ski has on its upper face a second fixing means, arranged in an appropriate manner, to be able to cooperate with the transverse axis (11).
• the two parallel axes (10, 11) engaged in the complementary fixing means arranged on the upper face of the ski define a support zone which makes it possible, during impulses, to obtain an optimal thrust.
• the first axis disposed furthest forward has a curved shape (15), directed forward to facilitate the release during falls, so that the assembly behaves well as a safety binding.
• the first fixing means is in the form of a hook (20), while the second means (21) parallel to (20), is also in the shape of a hook, the front face (22) of which forms a ramp, like bicycle shoes, to allow quick release in the event of a fall.
• the second attachment means (11,21) is arranged at the metatarsophalangeal joint.
