Definitions

  • the present invention relates to an article of footwear such as a walking or sports shoe.
  • This type of shoe comprises an upper connected to a sole assembly in its lower part.
  • the stem is composed of a vamp and quarters.
  • the vamp generally delimits an upper opening located at the user's instep.
  • the shoe incorporates a tightening system comprising at least one lace crossing a series of loops bordering the upper opening.
  • a classic solution consists in perforating the vamp with several holes located at the edge of the upper opening. Each of these openings is usually reinforced to form an eyelet through which the shoelace passes. This construction requires the lace to pass under the vamp, which can generate a hard point when tightening and thus not be very comfortable for the user. In addition, these openings are not very insulating.
  • Another solution consists in fixing on the slap, a loop, a hook or a loop, metallic or plastic. This insert is intended to guide the lace along a defined lacing path. This solution is more complex and expensive because it requires fixing additional parts. In addition, the use of added loops implies an extra thickness of the vamp at the level of the loops which can be the cause of a collision with an external element.
  • An alternative solution consists in turning several straps or portions of a yoke back on themselves, in order to form loops through which the lace will pass. Each loop then forms a loop of the tightening system.
  • This construction is simple and economical. However, this construction also induces an extra thickness of the vamp at the level of the loops due to the superimposition of the strap or portion of the yoke at the level of the folding/turning over. This extra thickness can also be the cause of a collision with an external element.
  • the object of the invention is to propose a construction of an article of footwear in which the loops of the tightening system are as close as possible to the upper, in an integrated manner with the vamp.
  • One aim is in particular to provide loops which are particularly flat, not very bulky and which reduce the surfaces for catching with an external element.
  • Another object is to provide a comfortable tightening system.
  • Another object is to provide an economical clamping system.
  • This specific shoe construction makes it possible to design particularly flat and low-volume loops that fit completely into the vamp of the upper.
  • the roughness protruding from the vamp is reduced. Consequently, the risk of snagging on an external element, such as a branch or a root, is reduced, unlike a construction comprising loops formed by loops or inserts.
  • this construction turns out to be soft and flexible. This makes it possible to avoid having "hard points" when tightening, which significantly improves the comfort of gripping the foot.
  • the proposed construction proves to be particularly advantageous from an industrial point of view. Indeed, these loops can be made with conventional industrial means. The assembly of the vamp can thus be done flat, in particular at the level of the upper connection between the first wall and the yoke. Thanks to this construction, the process for making these loops could be easily automated.
  • lateral and “medial”, conventionally, are understood as facing outward and inward, 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 medial-lateral direction (for a left foot) 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 sagittal plane Ps is a plane perpendicular to a Y axis.
  • a “shoe” is defined by a “sole assembly” and an “upper”.
  • the "sole” is the lower part of the shoe between the foot and the ground. This is the “underside” of the shoe.
  • the sole assembly is positioned opposite the sole of the foot.
  • the “upper” is the upper part of the shoe enveloping the foot and possibly part of the ankle, with the exception of the "underside” of the foot. This is the “top” of the shoe.
  • the upper is secured to the peripheral edge of the sole assembly. It should be noted that certain elements of the shoe can form both part of the sole and part of the upper.
  • THE figures 1 to 5 illustrate the construction of an article of footwear according to a first embodiment of the invention in a sports shoe 1.
  • the sports shoe 1 for the left foot represented is a running shoe, but could be a completely different type of sports shoe.
  • This shoe 1 is represented in perspective, seen from above in the figure 1 . It comprises an upper 2, which surmounts a sole assembly 3.
  • the sole assembly 3 generally comprises a damping layer 31 and a wear layer 32 covering the underside of the damping layer 31 and intended to come into contact with the ground. .
  • a clean sole 5 can be inserted inside the upper 2. This optional layer is intended to be positioned directly under the foot.
  • Rod 2 comprises several components.
  • the upper or vamp 21 constitutes a first component. It covers the upper, frontal, lateral and medial parts of the forefoot.
  • the vamp 21 comprises an upper opening 215, at the level of the instep, closed off by a tongue 22.
  • the vamp does not include an opening above the level of the instep.
  • the vamp is then continuous between its medial edge and its lateral edge, at the level of the instep.
  • the vamp generally comprises at least one flexible and, preferably extensible, portion in the area of the instep.
  • the tongue 22, optional, constitutes a second component of the rod. It is secured to the vamp 21.
  • the tongue is positioned so as to cover the instep of the user's foot when it is inserted into the shoe.
  • Lateral 23L and medial 23M quarters constitute third and fourth components of the stem. They form the socket of the heel and cover the rear, lateral and medial parts of the hindfoot.
  • the quarters 23L, 23M extend the vamp 21 at the rear of the latter in order to form a continuous envelope covering the top and all the sides of the foot.
  • the upper edges of the quarters 23L, 23M and of the tongue 22 or of the vamp 21 delimit an opening for introducing the foot into the shoe.
  • the upper 2 can be reinforced locally to ensure a hold of the upper and/or to protect the foot.
  • a "stub” may cover the front end of the rod.
  • a “buttress” can reinforce the part of the upper 2 surrounding the heel.
  • the components of the rod 2 can be separate parts. Alternatively, certain components or all of the components form a unitary part by being, for example, produced with the same process (knitting, weaving, etc.). Some components may also comprise several parts assembled together in any way known per se, for example by stitching, gluing or welding. According to certain embodiments, certain components of the upper 2 can extend under the foot to form a part of the sole assembly 3 or conversely, certain components of the sole assembly 3 can extend upwards, from the periphery of the sole assembly, to form a part of the stem 2.
  • the rod 2 extends in length from a rear end 2R to a front end 2F, and in width between a lateral side 2L and a medial side 2M.
  • the vamp 21 comprises a first wall 211 connected to the sole assembly 3.
  • the first wall 211 is, conventionally, fixed to an insole 33, for example, by sewing.
  • the subassembly composed of the first wall 211 and the insole 33 is then assembled to the upper surface of the damping layer 31 of the sole assembly. This assembly can be glued.
  • THE figure 4 , 7 And 9 illustrate this type of assembly.

  • This first wall 211 can be a woven, non-woven or knitted textile, a film, or embroidered threads.
  • the first wall 211 delimits the upper opening 215.
  • the lateral and medial edges of the upper opening carry loops 210 intended to receive a portion of a lace 41.
  • a lace 41 can be a cord, wire or cable.
  • the lace 41 is preferably made of plastic material.
  • the lace is composed of an outer sheath in PolyESTer (PES), PolyAmide (PA) or PolyTetraFluoroEthylene (PTFE).
  • the section of the lace 41 is substantially circular.
  • the shoe 1 comprises a tightening system 4 composed of the lace 41, the loops 210 and, possibly, a blocker 42 allowing the length of the lacing to be adjusted. .
  • This tightening system greatly contributes to the good support of the foot.
  • the invention relates more specifically to the construction of loops 210 of this tightening system.
  • At least two loops 210 are designed as follows.
  • the at least two loops are intended to receive a portion of lace 41, these at least two loops being arranged, respectively, on either side on the other side of a sagittal plane Ps of the article of footwear.
  • the at least two loops can be arranged symmetrically with respect to the sagittal plane Ps or, alternatively, arranged in staggered rows.
  • the sagittal plane Ps can be median or laterally shifted. In the latter case, the tightening system is then eccentric with respect to the median sagittal plane of the shoe.

  • This yoke 212 can be a woven, non-woven or knitted textile, a film, embroidered threads.
  • This yoke 212 is fixed to the first wall 211 by means of a first fastening means 213 located in a first connection zone 213Z close to a sagittal plane Ps, and therefore, in this example, close to an edge of the upper opening 215.
  • the term “close” means that the first connection zone 213Z is located closer to the sagittal plane, in the upper part of the first wall, than to the lower part of the first wall, part connected to the sole.

  • the upper limit of the first connection zone 213Z is advantageously distant from the sagittal plane by at least one centimeter and, advantageously, by less than three centimeters.
  • This first connection zone can extend to a lower limit fifteen millimeters from the upper limit.
  • this first fastening means 213 creates an upper connection between the first wall 211 and the yoke 212.
  • the yoke 212 is also fixed on the first wall 211 thanks to a second fastening means 214 located in a second connection zone 214Z distant from the first connection zone 213Z, moving away from the sagittal plane Ps and therefore from the upper opening 215 in this example.

  • the loops of the prior art are made by straps folded over on themselves so as to form a loop for the passage of a portion of the lace.
  • the specificity of the construction according to the invention is that the yoke 212 is assembled to the first wall 211 so as to be superimposed directly on the first wall 211, without folding or turning over part of the yoke 211.
  • the outer surface 211e of the first wall 211 is very close to the inner surface 212i of the yoke 212, or even almost in contact, face against face.
  • the first wall is thus covered by a layer having only the thickness of the yoke 212.
  • This design makes it possible to obtain a loop 210 which is particularly flat and compact, light, aesthetic, comfortable, simple and economical to produce.
  • the bridge produced by part of the yoke is fixed only to the outer surface of the first wall, this makes it possible to improve the insulation of the shoe, by reducing the thermal bridge at the passer-by level and water infiltration.
  • the manufacturers will carry out several tests to ensure that the tightening system does not deteriorate in use. For example, the submitter will conduct at least the following tests.
  • a tensile test consists of inserting a lace or cable through the loop. Then, a tensile force is exerted at the free ends of the lace, in a direction corresponding to the normal traction of the lacing. The threshold force necessary to cause the deterioration of the loop is then measured. This threshold effort must be greater than a targeted reference value.
  • An abrasion test consists of inserting a lace or cable through the loop. Then a reference mass is suspended at one end while orienting the lace so that the tension is oriented in a direction corresponding to the normal traction of the lacing. Finally, an alternating traction is exerted at the other end so as to cause a to-and-fro movement of the lace at the level of the loop, according to a determined stroke. The wear of the lace and of the loop is then analyzed after a targeted number of reference cycles, a cycle being a round trip or back and forth of the determined stroke. The loop and the lace must show acceptable normal wear, the tightening system must remain functional.
  • the claimed construction is designed to comply with these tests.
  • the yoke 212 comprises at least two layers, an outer layer 2120 and an inner layer 2121.
  • the outer layer 2120 can be made with one of the materials previously described as the constituent material of the yoke.
  • the inner layer 2121 is made with a low abrasive material.

  • the internal layer 2121 covers at least the zone located between the two connection zones 213Z, 214Z.
  • the internal surface of the internal layer 2121 is considered here as constituting the internal surface 212i of the yoke 212.
  • the internal layer 2121 can be a coating affixed, locally or entirely, to the internal surface of the external layer 2120, for example, by projection, impregnation or any other equivalent means.
  • the inner layer 2121 can be a distinct component, attached and fixed on the inner surface of the outer layer 2120.
  • the added component can be a fabric, a textile, a plate...
  • this added component can be attached to yoke 212 by any suitable means. It can be gluing, stitching or whatever.
  • the internal layer 2121 is produced by a PolyESTer fabric glued and sewn locally on the internal surface of the yoke.
  • This inner layer 2121 of low-abrasive material contributes to facilitating compliance of the loop with the abrasion test as defined previously, by protecting the outer layer 2120 from wear by friction generated by the sliding of the lace inside the loop.
  • This construction consisting in having an added component makes it possible to limit, to a functional zone, the use of low-abrasive material which can prove to be costly. A more economical material can then be used for the outer layer.
  • the yoke 212 is monolayer.
  • this single layer can advantageously be made with a low-abrasive material.
  • the thickness of the yoke is less than 1.5 millimeters. This makes it possible to make the loop particularly flat.
