Definitions

  • the present invention relates to a snowboard boot, in particular a boot of the flexible type suitable for the practice of specialized disciplines such as "free ride” and "free style".
  • a boot comprises a largely flexible upper as opposed to shoes of the "rigid” type adapted to the practice of the discipline of surfing in the Alps which have a rigid external shell generally associated with a cuff also rigid possibly articulated on the shell.
  • Figure 2 shows, in fact, the position in lateral flexion of the lower leg anatomically.
  • the angle of inclination ⁇ is equal to the sum of the angle of inclination ⁇ 1 obtained by pivoting the heel and the angle of inclination ⁇ 2 obtained by pivoting around the ankle joint.
  • the heel In the context of the use of a rigid shoe, the heel cannot, in principle, pivot around the angle ⁇ 1 due to the stiffness of the upper, and the articulation around the ankle can only be favored by the adaptation of an articulated collar.
  • the rigid shoe generally allows good transmission of support but blocks natural deformations of the foot and ankle during flexion movements of the leg in the practice of certain disciplines such as "free ride” or "free style".
  • Patent AT 2277/92 relates to a "rigid" type surf shoe having a shell, a cuff and a sole which is provided with a bearing surface with two elastic sole elements arranged laterally one next to the 'other.
  • the goal is to allow the shoe to be able to tilt about a pivot axis inclined relative to the median longitudinal plane.
  • This solution certainly allows to spare the ligaments in the ankle region by the tilting exerted.
  • the drawback lies in the fact that it is the entire rigid rod which rocks laterally around the determined inclination axis. This results in a significant loss of sensations due to this lateral laxity and the retention of the foot inside the rigid shell, which ultimately is detrimental in driving the surf during the changes.
  • the object of the present invention is to provide a solution to the problems mentioned above.
  • it aims to propose a boot which allows lateral mobility of the leg which is very important for the production of figures linked to the practice of "free style” and “free ride”, while respecting the naturally twisted position of the foot and the flexion of the ankle at its joint.
  • Another object is to keep, at the same time, all the sensations and information captured by the foot of the surfer by authorizing, not a tilting of the whole of the shoe which would be contrary to the desired effect, but an accompaniment to the movement as natural as possible from the foot to the inside of the boot.
  • the three support zones represent in fact, the main anatomical support points of a bare foot.
  • the first heel support zone has, transverse to the vertical median plane oriented longitudinally, a generally convex shape.
  • the lateral rolling of the heel along ⁇ 1 is favored.
  • the front internal elements have comparatively different hardness characteristics.
  • the support zones being separated from each other, it is advantageous to be able to treat the mobility of the forefoot inside the boot by elements with different characteristics as required.
  • the external sole comprises in the heel support zone a rear housing in which is inserted a rear internal element made of flexible material and having good damping properties.
  • the cushioning effect in the heel area provides additional comfort to the user when receiving jumps.
  • the boot illustrated in Figure 3 is intended for the practice of surfing. It has a part of the upper which has been deliberately trivialized but which generally relates to what specialists call a "flexible" boot.
  • such a boot has an outer sole of wear 1 which will be detailed later, an inner part 2 flexible and padded, in the form of a slipper which can rise more or less high on the calf, and an outer part 3 called rod whose flexibility is also important but which can be provided with buttresses, or even stiffening inserts or an internal or external articulated spoiler.
  • Such boot structures have been detailed according to different versions in patent application DE-A1-43 33 503, or even in the French application not yet published n ° 94 08872 belonging to the plaintiff.
  • the sole 1 of the boot according to the invention is made of hard material resistant to abrasion. It comprises three support zones 10, 11, 12 which are distinct and independent of one another constituting summarily a support triangle 6, so that the boot is at rest posed in a single position relative to its support without risk of limping. Such a defect is moreover very frequent on the soles of sports shoes obtained by vulcanization or by injection.
  • the sole also has a fastening means 5 located between the metatarsal region and the heel region.
  • the means is central, that is to say that it is located inside the lift triangle 6, between the front support zones 11, 12 and the heel support zone 10.
  • the attachment means 5 is part of a set for retaining the boot on the surf which has been the subject of French patent applications not yet published No. 9306006 and No. 9408872 belonging to the applicant.
  • the attachment means 5 of the sole has a recess 50 oriented transversely to the longitudinal direction materialized by the axis II 'of the sole and a section 51 oriented along the longitudinal direction of the axis II 'of the sole.
  • the other part of the device has complementary shapes intended to cooperate with the recess 50 and a locking member intended to cooperate with the profile 51.
  • attachment means 5 can also be more or less offset towards the external (EXT) or internal (INT) side with respect to the median longitudinal axis I-I 'shown.
  • the outer sole 1 is preferably a cup sole well known to those skilled in the art and which is characterized by the fact that it has raised edges 13 at its periphery as shown in FIGS. 5 and 6.
  • a inside, the sole further comprises two front housings 21, 22 located in the two support zones 11, 12 of the metatarsal region.
  • front internal elements 31, 32 of flexible and elastically compressible material.
  • the front internal elements have comparatively different mechanical characteristics to favor the movement of the forefoot on the internal or external side as appropriate.
  • the elements have different hardness characteristics.
  • the sole also includes a rear housing 20 into which is inserted a rear internal element 30 made of flexible material and having good damping properties.
  • a rear internal element 30 made of flexible material and having good damping properties.
  • Such an element is made of microcellular material with a polymer matrix, preferably chosen from EVA, polyurethanes, polyethylenes and PVC. The hardness and density can be variable depending on the compression damping effect sought.
  • the heel support zone 10 has, transversely with respect to the longitudinal direction of axis II ′, a generally convex shape, as shown in FIG. 6, to favor the rolling of the heel on one side or the other during lateral flexion.
  • the external surface of the sole in the determined support zones 10, 11, 12 may have ridges 8 in relief or in hollow having the function of improving the grip during walking, in particular.
  • FIGS. 5 to 8 The internal structure of the shoe represented in FIGS. 5 to 8 has been deliberately simplified so as to show only the essential constituent means of the invention.
  • the boot is also likely to receive of course a first insole for mounting and a first insole.
  • Figures 7 and 8 show in cross section the behavior of the boot during a lateral bending stress at the location of the different support zones.
  • the front part of the boot, in the metatarsal region does not tilt during bending with respect to the median vertical plane P oriented longitudinally, but it is simply the front of the foot 7 which moves inside the boot and which exerts pressure on one of the elements 32 of elastically deformable material.
  • the sole is covered, in the region of the metatarsals at least, by a rod 4 formed by a flexible envelope which is connected to the edges 13 by gluing and / or sewing.
  • the lateral bending causes the sole part to roll, favored by its convex shape, so that an inclination ⁇ 1 of the ankle / boot assembly is obtained relative to the plane P as shown in figure 8.
  • FIG. 9 schematically shows the transformation of the lifting triangle 6 into a second triangle 60 after pivoting of the leg.
  • the first triangle 6 is defined by its support points 100, 110, 120 contained in the support zones 10, 11, 12. After pivoting, only the support point 100 actually moves, by the rolling effect from the heel, inside the heel support zone 10, to become point 100b.
  • the support points 100, 110, 120 can move very substantially in any direction depending on the support of the surfer.
  • it is not actually a fulcrum, properly speaking, but more, bearing surfaces with contours close to the bearing zones defined.
  • the materials constituting the outer sole one will choose from the group consisting of vulcanized rubbers and thermoplastic rubbers.
