Definitions

  • the present invention relates to a sports shoe, intended for sports requiring longitudinal mobility of the foot relative to the leg and good ankle grip and which is more specifically suitable for walking (hiking, trekking) or for skiing. background.
  • this is defined by repetitive cycles in which alternate, motor phases and rest phase; a motor phase corresponding to an impulse provided by one leg, being followed by a rest phase where one slides on the other leg, the skis remaining substantially parallel during these cycles.
  • the lower train works on sliding supports, which forces the skier to exert a thrust directed laterally, with respect to its trajectory, by making its skis diverge to rest on the edges .
  • the alternative step requires only a front / rear flexibility in the direction of movement for the movements of extension / flexion of the leg, while in the case of the skater's step, an additional requirement is required which is added to the previous one and which consists in obtaining a maximum rigidity of the shoe in the direction perpendicular to the movement for good grip of the ankle. It should be noted that the requirements for shoes for skating steps are the same as for walking shoes.
  • shoes with low upper for the practice of the alternative step on the one hand, and shoes with high upper for the practice of the skater's step or walking, on the other hand .
  • shoes with high articulated upper are desirable for hiking while shoes with low upper are necessary for the practice of sport requiring only one foot unwinding.
  • the articulation of the rigid collar on the low rod is located at the upper end thereof, the collar extending upward from its articulation, beyond the end. upper stem.
  • This document therefore teaches how to obtain, from a shoe with a low upper, a shoe with a high upper, which moreover is articulated, but does not solve the problem posed, namely to offer a shoe that can be used for the practice of the alternative step and the skater step.
  • these fixing means consist of an elastically deformable cabbage from the rear buttress and formed of a plurality of parallel elastic arms arranged around the transverse axis of articulation of the collar, and which engage by a transverse action, in a cylindrical hole of the collar until the hooks placed in a corolla on the end of the said arms, snap elastically onto the external face of the collar emerging from it.
  • FR-A-2 043 998 shows a sports shoe for the practice of ski touring and alpine skiing comprising a removable collar in accordance with the preamble of claim 1.
  • the object of the present invention is to remedy these various drawbacks and to provide a dual-use sports shoe, that is to say with a low upper or upper high articulated, easily transformable with simple means and without requiring special tools.
  • the invention relates to a sports shoe in particular for walking and / or cross-country skiing, obtained from a low rod (10) provided with a rear buttress (12) and comprising a rigid collar ( 13) intended to surround the lower leg and mounted articulated on the rear buttress (12) of the rod (10) at the upper level thereof, the collar (13) extending upwards from its articulation, beyond the end of the rod (10), the articulated mounting of the collar being effected by means of two projections (12a) disposed on each side of the buttress and defining the articulation, characterized in that the collar comprises in its articulation zone of the elastic locking means (20) which are specific to it capable of making it removable manually and cooperating elastically with the mounting with the projections (12a) of the buttress, these locking means being constituted by a jaw whose branches delimit between them a passage of i introduction of a projection, and at least one of the branches of which is elastically deformable when the projections pass.
  • a dual-use shoe is obtained, more particularly suitable for skating or hiking, if the collar is used to form a shoe with a high upper, or more particularly suitable for alternative walking or walking if, on the contrary, the collar is removed, thus making it possible to find an original shoe, with a low upper, without having to use any tool.
  • the jaw shape of the elastic locking means offers the advantage of being able to dispose of the collar itself, as a gripping means, making it possible to remove it by traction, with a single gesture, or to put it in place by grasping it. by its lateral sides.
  • the shoe shown by way of example in FIG. 1 is particularly suitable for skating or skating or for hiking and has the appearance of a shoe originally made up of a low rod 10, c ' that is to say a rod whose rigid parts do not extend in height beyond the malleoli, an outer sole 11 and a lacing system 20 of a type known per se.
  • the rod 10 is made of flexible material and is provided at the heel with a rear buttress 12 which can be produced in any way known per se.
  • This buttress 12 is preferably made of rigid synthetic material, and extends over the entire rear part of the shoe, all around the heel thereof.
  • This buttress 12 extends, in the region of the malleoli, to the top of the upper, for the reception of an articulated collar 13, and has at its upper end, at the level of these malleoli, on each side of the shoe , a projection or boss 12a extending outward substantially perpendicular to the wall of the buttress and adapted to be introduced into an associated cylindrical hole 13a, formed on each side of the collar 13 (see Figure 4).
  • Each boss 12a is also provided with a hole 12b for fixing the collar 13 by means of nails 19 (see FIG. 5).
  • the collar 13 can therefore be mounted articulated on the projecting parts 12a of the buttress of the rod at the upper end of the latter.
  • nails 19 can be replaced by any other connection method allowing rotation such as rivets.
  • the use of nails 19 is particularly advantageous, because it allows installation by simple application of pressure on the head 19a, without requiring a counterpart as in the case of rivets.
  • the nails 19 will advantageously be made of a relatively flexible material compared to a metal rivet, such as delrin, so that their head 19a follows the possible deformations of the rigid collar 13, for example during a torsion of the leg, such a construction making it possible to avoid the tearing of these nails during such a twist.
  • the articulated collar 13 is constituted by a cuff made of rigid material and in particular of a synthetic material such as that known under the trade name Pebax.
  • This collar 13 extends up to the bottom of the calf and surrounds the entire lower leg. It is open at its front part to allow the foot to be placed in the shoe and is provided with clamping means 15 of a type known per se, and constituted for example by hook-and-loop means.
  • This collar 13 is also provided at the rear with a notch 13b intended to facilitate the rearward rotation of this collar (cf. position in dotted lines in FIG. 1).
  • the large height of the collar 13 allows excellent lateral hold of the leg during skating or hiking, such a height also allowing greater distribution of the reaction forces over the leg. and, therefore, better comfort for the user.
  • the total and independent articulation of the collar 13 on the rod allows the latter to pivot freely and without any discomfort for the user.
  • the tongue 42, like the lacing system 40, of the shoe does not extend, in height, not beyond the flexion fold of the user's foot, so as not to hinder it. bending.
  • the position of the hinge pin 30 of the collar 13 on the rod is chosen so as to achieve the best compromise between comfort and an axis as close as possible to the natural position of the tibio-tarsal joint, depending different morphologies and foot sizes.
  • the collar 13 comprises in its articulation zone overlapping the top of the rod 10 with elastic locking means which are specific to it, capable of making it removable manually and cooperating in mounting with the projecting bosses 12a, integral of the buttress 12 and materializing the transverse articulation axis 30.
  • These means are arranged on either side of the articulation zone of the collar 13 and are constituted respectively by a jaw 20 of which at least one of the two branches 20a, 20b, in this case 20a is elastically deformable.
  • each jaw 20 delimit between them a passage, flared outwards over a large width L and opening out by its small width l into the aforementioned cylindrical hole 13a of diameter D1 substantially equal to that D2 of the boss 12a , but greater than the said small width l of the passage.
  • the passage delimits, in its small width l, with the hole 13a of diameter D1, two beads 21, 22 projecting on either side of the entrance to the hole 13a, which beads are suitable for retract elastically during the passage of the boss 12a between the branches 20a, 20b during assembly, by an engagement force exerted on their engagement faces 20c, 20d, to then return to their initial position after introduction of said boss 12a in the hole 13a of the jaw 20, and thus ensure its retention.
  • the width L of the flared part of the passage is at least equal to the diameter D2 of the boss 12a so as to allow its prior engagement in the passage, before snap-fastening in the hole 13a.
  • boss 12a could be eliminated and replaced by a nail 19 of a larger diameter, but the solution is not advantageous in terms of the rigidity of the locking assembly.
  • Figures 2 and 3 respectively show the stages of mounting a collar 13 on a rod 10 for the transformation of a shoe with a low rod into a shoe with a high rod.
  • the head 19a of the nail 19 has been removed by cutting.
  • the jaws 20 are formed at the bottom of the collar 13 along a longitudinal axis XX 'corresponding to a direction of engagement F of the collar 13 on the bosses 12a.
  • the axis XX ' here forms an angle ⁇ with a vertical axis YY' of the collar 13 and the direction of engagement F takes place generally towards the rear of the shoe.
  • the angle ⁇ shown is equal to approximately 45 ° relative to the axis yy 'but it can obviously be chosen by a greater or lesser value.
  • FIG. 6 essentially differs from the previous one, in that the jaw 20A is produced at the lower part of the collar 13A along a longitudinal axis corresponding or substantially parallel to the vertical axis YY 'of the collar 13A, which corresponds to an angle ⁇ zero.
