Definitions

  • the present invention relates to a walking or sports shoe.
  • the user When moving, walking or running, and more particularly on uneven terrain, as may be the case in the mountains, the user will seek the stability of his supports while maintaining a certain freedom of movement for more 'ease. This stability allows it to limit trauma and avoid injuries such as sprains or strains. To do this, he will wear shoes that provide good foot support.
  • Another type of construction consists of inserting a reinforcement provided with lateral and/or medial wings, between the shock-absorbing layer of an external sole and the upper. Foot support is good but the cushioning layer located under the reinforcement tends to add instability.
  • Another type of construction includes soft reinforcing strips surrounding the instep and extending up to the lacing system. The foot is thus well enclosed and relatively well maintained.
  • lateral support is not optimal. The risk of twisting the foot remains.
  • Another construction incorporates a rigid shell extending over mainly the entire length of the sole and including lateral and/or medial wings, going up towards the upper.
  • the side wings rise little on the upper and are not coupled to a flexible reinforcing strip associated with the lacing system.
  • the lateral support of the foot is relatively good.
  • the rigid shell provides stiffness, particularly for the movement of the foot, which penalizes the ease of movement of the foot.
  • EP 2 580 978 A1 discloses a sports shoe.
  • the aim of the invention is to provide an improved shoe.
  • One aim is in particular to offer a shoe construction ensuring very good lateral support of the foot.
  • Another goal is to offer a shoe construction allowing good ease of movement of the foot and in particular, good movement of the foot.
  • Another goal is to offer a comfortable shoe.
  • the sports shoe is characterized in that it further comprises a reinforcement composed of a rigid plastic material, having a hardness greater than 40 shore D, the reinforcement comprising a lateral wing fixed on a part of a lateral edge of the damping layer and on an external face of the flexible panel.
  • This shoe construction provides excellent lateral support for the foot.
  • the lateral support of the foot is ensured, on the one hand, by the inextensible panel adjusted by the tightening system and, on the other hand, by the rigid reinforcement superimposed on the base of the inextensible panel.
  • lateral support is reinforced.
  • the inextensible panel and part of the reinforcement are positioned so as to cover part of the lateral quarter of the upper, the holding elements, namely the inextensible panel and the reinforcement, are positioned opposite each other bu lateral edge of the foot, approximately at the level of the cuboid bone. This is where it is important to support the foot to improve stability.
  • This construction makes it possible to locate the stiffening elements in the strictly necessary locations without deteriorating the flexibility of the shoe and in particular, without penalizing the movement of the foot.
  • lateral and medial are understood as facing outwards and inwards respectively.
  • medial side of one foot or shoe faces the medial side of the user's other foot or shoe.
  • longitudinal refers to a heel-toe direction corresponding to the X axis while the term “transverse” refers to a lateral-medial direction corresponding to the Y axis and therefore substantially perpendicular to the longitudinal direction.
  • transverse refers to a lateral-medial direction corresponding to the Y axis and therefore substantially perpendicular to the longitudinal direction.
  • the vertical or down/up direction corresponds to the Z axis.
  • a “shoe” is defined by a “sole” and an “upper”.
  • the “sole” is the lower part of the shoe between the foot and the ground. This is the bottom of the shoe.
  • the “upper” is the upper part of the shoe surrounding the foot and possibly part of the ankle. This is the top of the shoe.
  • the upper is secured to the peripheral edge of the sole. Note that certain elements of the shoe can form both part of the sole and part of the upper.
  • THE figures 1 to 7 illustrate the construction of a sports shoe 1 according to a first embodiment of the invention.
  • the sports shoe 1 for the right foot shown is a running shoe, but could be a completely different type of sports shoe.
  • This shoe 1 is shown in perspective, seen from above, in the figure 1 . It comprises a rod 2, which surmounts a sole assembly 3.
  • the sole 3 comprises a superposition of layers between the ground and the bottom of the foot, as illustrated in Figure 4 .
  • the first layer is an insole 31. It is generally mounted removable inside the shoe.
  • the next layer located below the insole 31 is an insole 32.
  • This second layer 32 is generally fixed to the lower peripheral edges of the upper 2.
  • an external sole 33 under the insole 32.
  • This external sole 33 is generally fixed to the insole 32 in any manner known per se, for example, by gluing. This external sole 33 is intended to come into contact with the ground.
  • the outer sole 33 extends in length from a rear end 33R to a front end 33F, thus defining a length of the sole L33, in width between a lateral side 33L and a medial side 33M, thus defining a width of the sole W33 .
  • the external sole 33 comprises a damping layer 331 and a wear layer 332 and also part of a reinforcement 4 which will be described later.
  • the cushioning layer 331 is made of a material composed of cellular foam, for example, Ethylene-Vinyl Acetate (EVA) or ThermoPlastic Polyurethane (TPU). Other materials are possible.
  • EVA Ethylene-Vinyl Acetate
  • TPU ThermoPlastic Polyurethane
  • This layer 331 extends over substantially the entire length of the external sole L33, that is to say, at least 90% of the total length of the external sole.
  • the wear layer 332 is fixed on the cushioning layer 331 so as to cover a large part of the lower surface of the cushioning layer. This wear layer 332 is thus interposed between the damping layer 331 and the ground. As we see in the figures 1 to 3 And 7 , it can go up on the front part 33F of the sole so as to delimit the front end 33F of the sole. This wear layer 332 is intended to be systematically in contact with the ground. It thus ensures the grip or “grip” of the shoe. Generally, the wear layer 332 is made of rubber or ThermoPlastic Polyurethane (TPU).
  • TPU ThermoPlastic Polyurethane
  • the upper 2 comprises an envelope 21 which extends in length from a rear end 21R to a front end 21F, in width between a lateral side 21L and a medial side 21M, and in height from the sole 3 up to an upper end 21U, the upper end 21U having a shoe opening 22, the shoe opening 22 having a rear subdivision 22R and a front subdivision 22F.
  • the envelope 21 is intended to surround a large part of the foot. It includes an upper covering the front of the foot and lateral and medial quarters covering the back of the foot and in particular the heel.
  • the envelope is made of a flexible material so that it can conform well to the shape of the foot. A multitude of materials can be considered.
  • the envelope 21 can be reinforced locally to ensure that the upper is held in place and/or to protect the foot.
  • a “hard toe” 23 can cover the upper part of the front end 21F of the envelope 21.
  • the front subdivision 22F is delimited by edges of the envelope, at the level of the vamp. Each of these lateral and medial edges carries a series of loops 252 intended to receive a lace 251 of a tightening system 25.
  • the tightening system includes the loops 252, the lace 251, passing through the loops 252 and a blocker, not shown, allowing the length of the lace engaged with the loops to be adjusted, at the level of the front subdivision 22F.
  • the tightening system allows the edges of the front subdivision 22F to be brought together, ensuring that the instep is gripped by the upper. This tightening contributes greatly to the good support of the foot.
  • the rod 2 also comprises an inextensible flexible panel 26 covering a lateral part of the envelope 21.
  • an inextensible panel is a panel made of a material which deforms little or not when we stretch it.
  • the inextensible panel can be a canvas, a fabric, a film. To obtain the characteristic of inextensibility, it can be thanks to a coating applied to a material, for example, by coating, by projection, by printing.
  • the flexible panel 26 extends over the entire height of the upper, from the sole 3 to the lateral edge of the front subdivision 22F.
  • the lower end of the flexible panel 26 is thus fixed on the envelope 21 at the level of a portion of the lateral junction 123L between the upper 2 and the outer sole 33.
  • the upper end of the flexible panel 26 carries a guide member 253 of a portion of the lace 251 of the tightening system 25 of the shoe.
  • This guide member is positioned in place of a loop 252 of the series of passers-by positioned on the side edge of the front subdivision 22F.
  • the guide member 253 is a loop.
  • Other types of guide member can be considered. For example, it can be a hook.
  • the flexible panel 26 is fixed to the envelope 21 by any appropriate means. This can be by gluing and/or welding and/or seams. Here, the lower part of flexible panel 26 is sewn to the envelope 21.
  • the figures 1 , 2 And 4 illustrate the assembly seams 27.
  • the flexible panel 26 extends over a portion of the junction 123L between a first limit 1231 positioned at a distance of one eighth of the outer sole length L33 from the rear end 33R and a second limit 1232 positioned at a distance of half the length of the outer sole. This positioning ensures that the flexible panel 26 is located opposite a specific area of the foot for which support is necessary to improve the stability of the foot.
  • the flexible panel 26 forms a strip whose edges converge upwards.
  • the strip is oriented along a main axis 261, inclined forward by an angle ⁇ of between 25 and 75° relative to a horizontal plane XY. This inclination allows the reinforcement to be positioned by the flexible panel only locally. This makes it possible to avoid stiffening the envelope in areas where flexibility is sought to facilitate the movement of the foot and in particular the rolling of the shoe. This improves ease of movement.
  • the flexible panel 26 is fixed on the envelope 21 over at least the lower quarter of the height of the flexible panel. Otherwise formulated, the flexible panel 26 is fixed on the envelope on at least the lower quarter of the panel along the main axis 261 of the flexible panel 26.
  • the flexible panel 26 is completely integral with the envelope 21. The reinforcing function is fully ensured in this important area for stability. There is no risk of an external element being inserted between the flexible panel 26 and the envelope 21. This avoids any discomfort or hard point (local pressure) during tightening.
  • the flexible panel 26 is separated from the envelope 21 over at least the upper half of the height of the flexible panel. Otherwise formulated, the flexible panel 26 is separated from the envelope 21 on at least the upper half of the panel along the main axis 261 of the flexible panel 26.
  • the fact that the flexible panel is not secured to the envelope in its part high makes it possible not to stiffen the envelope 21 at the level of the vamp. This will make it easier to put your foot on.
  • the inextensible flexible panel 26 is coupled with a reinforcement 4 composed of a rigid plastic material, having a hardness greater than 40 shore D, preferably greater than 50 shore D.
  • a reinforcement 4 composed of a rigid plastic material, having a hardness greater than 40 shore D, preferably greater than 50 shore D.
  • a material can be a PolyAmide (PA) , A ThermoPlastic Polyurethane (TPU), a PolyEster (PE) or even a composite material, for example based on carbon fibers.
  • PA PolyAmide
  • TPU ThermoPlastic Polyurethane
  • PE PolyEster
  • a lateral support of the foot is greatly improved by this coupling of the reinforcement 4 with the flexible panel 26.
  • a lateral part 41 of the reinforcement 4 which will be designated “lateral wing” hereinafter, is fixed on an external face 262 of the flexible panel 26 by any appropriate means. This can be by gluing, welding, sewing.
  • the side wing 41 of the reinforcement 4 covers at least a quarter of the height of the flexible panel 26.
  • the side wing 41 of the reinforcement 4 covers the flexible panel 26 by at least 1.5 centimeters, in height, relative to the lateral junction 123L between the upper 2 and the outer sole 33.
  • the lateral wing 41 of the reinforcement 4 does not rise above half the height of the upper 2 so as not to stiffen the envelope 21 at the level of the vamp. This will make it easier to put your foot on.
  • the side wing 41 can be dimensioned so that the rigidity of the wing decreases the further away from the external sole 33.
  • the thickness of the wing can decrease as a function of the height of the wing, the higher you are, the thinner the wing. This progressive variation in stiffness makes it possible to provide flexibility in the upper part of the wing, an area where we may need to facilitate deformation to help insert the foot into the shoe.
  • the lateral wing 41 of the reinforcement 4 is also fixed on a part of a lateral edge 3311 of the damping layer 331. This makes it possible to contain the damping layer by preventing it in particular from move sideways. It is thus advantageous for the side wing 41 of the reinforcement 4 to cover part of the external sole 33.
  • the reinforcement 4 includes anchoring means making it possible to hold the reinforcement in place and prevent the lateral wing 41 from sagging or flexing laterally.
  • the reinforcement 4 comprises a transverse branch 42 covering part of a lower face 3312 of the damping layer 331.
  • the transverse branch 42 extends transversely, over substantially the entire width W33 of the external sole. 33.
  • the transverse branch 42 and the lateral wing 41 are oriented substantially at 90°, one relative to the other. This configuration ensures very good anchoring of the reinforcement 4 which makes it possible to limit the bending of the side wing 41.
  • the transverse branch 42 is positioned, longitudinally, only facing a transition zone 3313 of the lower face 3312 of the cushioning layer 331 located below the arch of the foot.
  • This transition zone 3313 is located between two zones of contact with the ground. These contact zones are provided on the wear layer 332. They are provided with crampons. Thanks to this arrangement, there is no rigid part of the reinforcement 4 facing the crampons. This allows for better grip and cushioning because the studs can more easily deform vertically.
  • the transverse branch is located in the transition zone, this avoids stiffening the external sole in the metatarsal zone. The sole can more easily flex around a transverse axis Y, which improves the behavior of the shoe and in particular the movement of the foot.
  • the reinforcement 4 also includes a medial wing 43 which raises the external sole 33 to cover only part of a medial edge 3312 of the cushioning layer 331.
  • the medial wing 43 does not cover any medial part of the rod 2.
  • the medial wing 43 extends further upwards to cover a medial part of the rod 2. The medial wing 43 makes it possible to reinforce the anchoring of the reinforcement 4, and more particularly the maintaining the transverse position of the reinforcement.
  • the reinforcement is constructed to form a “U”.
  • the anchor can be a hoop, fixed to the outer sole and running along the rear junction 123R between the upper 2 and the outer sole 33, at the heel level.
  • the part of the side wing 41 facing the flexible panel 26 forms a plate whose edges converge upwards.
  • the plate is oriented along a main axis 411, inclined forward by an angle ⁇ of between 25 and 75° relative to a horizontal plane XY. This inclination allows the reinforcement to be positioned by the reinforcement only locally. This makes it possible to avoid stiffening the envelope in areas where flexibility is sought to facilitate the movement of the foot and in particular the rolling of the shoe. This improves ease of movement.
  • the main axis 411 of this covering part can be coincident with or substantially parallel to the main axis of the flexible panel 26.
  • the part of the side wing 41 facing the flexible panel 26 extends over a portion of the junction 123L between a first limit 1231 positioned at a distance of one eighth of the length L33 of the outer sole from the rear end 33R and a second limit 1232 positioned at a distance of half the length of the outer sole.
  • This positioning ensures that the lateral wing 41 of the reinforcement 4 is located opposite a specific area of the foot for which support is necessary to improve the stability of the foot.
  • lateral support For lateral support to be improved, it is important to have lateral support opposite the Lisfranc joint or tarsometatarsal joint of the foot.
  • This Lisfranc 5 joint whose space extends transversely from one edge of the foot to the other, unites the three cuneiforms and the cuboid to the five metatarsals.
  • the foot pivots around this joint which is, in fact, significantly stressed. In the absence of support, there is a greater risk of twisting the foot.
  • the flexible panel 26 and the side wing 41 of the support 4 are arranged so that a part of the flexible panel 26 and/or the side wing 41 is positioned facing the articulation of Lisfranc 5 or tarsometatarsal joint of the foot when the foot is in the shoe. This positioning is illustrated in Figure 7 .
  • This construction is particularly effective in preventing the risk of external ankle sprains.
  • the inextensible flexible panel 23 does not carry a guide member 253 of a portion of a lace 251 of a tightening system 25 of the shoe.
  • the upper end of the flexible panel is then directly fixed to the rod, for example, by sewing.
  • the lateral edge of the front subdivision 22F comprises a series of loops 252 arranged symmetrically to the series of loops 252 of the medial edge of the front subdivision 22F.
  • the tightening system 25 does not include a loop associated with the flexible expandable panel 23.
  • the lower part of the reinforcement 4 is inserted between the damping layer 331 and part of the wear layer 332 of the outer sole 33.
  • the lower part of the reinforcement 4 covers also a part of the wear layer 332.
  • the reinforcement can completely cover a portion of the assembly of the damping layers 331 and wear layers 332 of the external sole 33. This construction can facilitate the manufacturing process of the external sole 33, the reinforcement being able to be added after the assembly of the damping layers 331 and wear layers 332.
