Abstract
Description
Title of the invention: Footwear
[0001] The present invention relates to an item of footwear such as a walking or sports shoe.
[0002] This type of shoe comprises an upper connected to a sole in its lower part. The upper is composed of a vamp and quarters. The vamp generally delimits an upper opening located at the level of the user's instep. To ensure a good fit for the foot, the shoe incorporates a tightening system comprising at least one lace passing through a series of loops bordering the upper opening.
[0003] Several constructions are possible to produce these passers-by.
[0004] A classic solution is to perforate 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 lace passes. This construction requires the lace to pass under the vamp, which can create a hard point when tightening and thus not be very comfortable for the user. In addition, these openings are not very insulating.
[0005] Another solution is to attach a loop, hook or loop, made of metal or plastic, to the flap. This added part is intended to guide the lace along a defined lacing path. This solution is more complex and expensive because it requires attaching additional parts. In addition, the use of added loops involves an excess thickness of the flap at the loops, which can cause it to catch on an external element.
[0006] An alternative solution consists of 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 excess thickness of the flap at the loops due to the superposition of the strap or portion of yoke at the level of the folding / turning. This excess thickness can also be the cause of a snag with an external element.
[0007] The aim of the invention is to propose a construction of a footwear article in which the loops of the tightening system are as close as possible to the upper, in a manner integrated into the vamp.
[0008] One aim is in particular to propose particularly flat, small-volume loops that reduce the areas of contact with an external element.
[0009] Another aim is to provide a comfortable tightening system.
[0010] Another aim is to provide an economical clamping system.
[0011] Another aim is to propose a clamping system comprising loops that can be produced automatically.
[0012] The invention provides an article of footwear composed of an upper comprising a vamp comprising
[0013] - a first wall, - at least two loops intended to receive a portion of a lace, each loop being arranged on either side of a sagittal plane of the footwear item.
[0014] The footwear article is characterized by the fact that each loop is defined by
[0015] - the interstitial space between the first wall and a panel locally covering an external surface of the first wall, the interstitial space having an anterior opening and a posterior opening through which a portion of the lace passes, and - an upper connection between the first wall and the yoke, the upper connection being achieved using a first securing means located in a first connection zone close to the sagittal plane,
[0016] the yoke overlapping the first wall without folding.
[0017] This specific shoe construction makes it possible to design particularly flat and compact loops that fit completely onto the vamp of the upper. By perfectly matching the shape of the vamp, the protruding roughness of the vamp is reduced. Consequently, the risk of catching on an external element, such as a branch or a root, is reduced, unlike a construction comprising loops formed by loops or added parts. Furthermore, this construction proves to be supple and flexible. This makes it possible to avoid having “hard points” during tightening, which significantly improves the comfort of gripping the foot. Furthermore, the proposed construction proves to be particularly advantageous from an industrial point of view. Indeed, these loops can be produced using conventional industrial means.The assembly of the flap can thus be done flat, particularly at the level of the upper connection between the first wall and the yoke. Thanks to this construction, the process of producing these loops could be easily automated.
[0018] According to advantageous but not obligatory aspects of the invention, such an article of footwear may incorporate one or more of the following characteristics, taken in any technically admissible combination:
[0019] - The insert comprises an inner layer made with a low-abrasive material. Advantageously, the insert comprises at least two layers, an outer layer and an inner layer, the inner layer being an added component and fixed to the inner surface of the outer layer. - The first method of joining is a zigzag seam. Advantageously, this seam has a length greater than 5 mm and a width greater than 2 mm. - The insert is fixed to the first wall by a second securing means located in a second connection zone distant from the first securing means, moving away from the sagittal plane, so that the distance between the two securing means is between 5 and 10 mm. - The insert is connected to the sole of the footwear item. - The same yoke is used and sized to make several loops. Advantageously, the same yoke allows loops to be made on either side of a sagittal plane.
[0020] Other characteristics and advantages of the invention will be better understood with the aid of the description which follows, with reference to the appended drawings illustrating, according to non-limiting embodiments, how the invention can be implemented, and in which:
[0021] [Fig-1] [Fig.l] is a front perspective top view of a shoe for left foot according to a first embodiment of the invention.
[0022] [Fig.2] [Fig.2] is a side view of the shoe of [Fig.l].
[0023] [Fig.3] [Fig.3] is a detail view 3 of a loop of the shoe of [Fig.l].
[0024] [Fig.4] [Fig.4] is a schematic “frontal” section along IV-IV of [Fig.2].
[0025] [Fig.5] [Fig.5] is a detail view 5 of a loop of the shoe of [Fig.4].
[0026] [Fig.6] [Fig.6] is a front perspective top view of a shoe for left foot according to a second embodiment of the invention.
[0027] [Fig.7] [Fig.7] is a schematic “frontal” section of [Fig.6].
[0028] [Fig.8] [Fig.8] is a front perspective top view of a shoe for left foot according to a third embodiment of the invention.
[0029] [Fig.9] [Fig.9] is a schematic “frontal” section of [Fig.8].
[0030] [Fig. 10] [Fig. 10] is a schematic “front” section of a fourth embodiment of the invention.
[0031] In the remainder of the description, use will be made of terms such as "vertical", "upper", "lower", "top", "bottom", “transverse”, “lateral”, “medial”, “right”, “left”, “horizontal”, “anterior”, “posterior”, “in front”, “behind”, “before”, “back”. These terms should be interpreted in fact in a relative manner in relation to the position that the shoe occupies on the foot of a user in normal posture, and the normal direction of forward movement of a user. A normal posture is considered to be a configuration for which the sole is placed flat on a horizontal floor.
[0032] The terms "lateral" and "medial", conventionally, are understood as facing outward and inward respectively. Thus, the medial side of one foot or shoe faces the medial side of the user's other foot or shoe.
[0033] The term "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.
[0034] The terms "interior" and "internal" designate the elements directed towards the inside of the shoe, oriented towards the user's foot when the latter is housed in the shoe. Conversely, the terms "exterior" and "external" designate the elements directed towards the outside of the shoe, exposed to the external environment.
[0035] In the description, 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. It is the “bottom” of the shoe. The sole 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 “bottom” of the foot. It 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 a part of the sole and a part of the upper.
[0036] 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 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 [Fig.l]. It comprises an upper 2, which surmounts a sole 3. The sole 3 generally comprises a cushioning layer 31 and a wear layer 32 covering the lower face of the cushioning layer 31 and intended to come into contact with the ground. Optionally, a sockliner 5 can be inserted inside the upper 2. This optional layer is intended to be positioned directly under the foot.
[0037] The rod 2 comprises several components.
[0038] The upper or vamp 21 constitutes a first component. It covers the upper, frontal, lateral and medial parts of the forefoot. In this example, the vamp 21 comprises an upper opening 215, at the instep, closed by a tab 22. Alternatively, as illustrated in Figures 8 to 10, the vamp does not comprise an upper opening at the instep. The vamp is then continuous between its medial edge and its lateral edge, at the instep. In this case, the vamp generally comprises at least one flexible portion and, preferably- highly stretchy, in the instep area.
[0039] The optional tongue 22 constitutes a second component of the upper. 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.
[0040] Lateral 23L and medial 23M quarters constitute third and fourth components of the upper. They form the heel cup and cover the rear, lateral and medial parts of the rearfoot. Quarters 23L, 23M extend the vamp 21 at the rear thereof in order to form a continuous envelope covering the top and all sides of the foot. The upper edges of quarters 23L, 23M and of the tongue 22 or the vamp 21 define an opening for the introduction of the foot into the shoe.
[0041] The upper 2 may be reinforced locally to ensure the upper is held in place and / or to protect the foot. For example, a “tip” may cover the front end of the upper. Similarly, a “buttress” may reinforce the part of the upper 2 surrounding the heel.
[0042] The components of the upper 2 may be separate parts. Alternatively, some or all of the components form a unitary part by being, for example, produced using the same process (knitting, weaving, etc.). Some components may also comprise several parts assembled together in any manner known per se, for example, by sewing, gluing or welding. According to certain embodiments, some components of the upper 2 may extend under the foot to form a part of the sole assembly 3 or, conversely, some components of the sole assembly 3 may extend upwards, from the periphery of the sole assembly, to form a part of the upper 2.
[0043] 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.
[0044] The vamp 21 comprises a first wall 211 connected to the sole 3. The first wall 211 is, in a conventional manner, fixed to a mounting insole 33, for example, by sewing. The subassembly composed of the first wall 211 and the mounting insole 33 is then assembled to the upper surface of the cushioning layer 31 of the sole. This assembly can be glued. Figures 4, 7 and 9 illustrate this type of assembly.
[0045] This first wall 211 can be made with one of the following materials: a PolyEster (PES, PET), a PolyAmide (PA), a PolyUrethane (PU), a PolyVinyl Chloride (PVC), a natural material. Among the natural materials, one of the following materials can be used: leather, linen, hemp, wool. One can also use so-called “bio-manufactured” materials, material made from biological organisms (mycelium, bacteria, etc.). This material can also incorporate a proportion of recycled material.
[0046] This first wall 211 can be a woven, non-woven or knitted textile, a film, embroidered threads.
[0047] In this example, 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. For the purposes of the invention, a lace 41 may be a cord, a wire or a cable. The lace 41 is preferably made of plastic. For example, the lace is composed of an external sheath made of PolyESter (PES), PolyAmide (PA) or PolyTetraFluoroEthylene (PTFE). Advantageously, the section of the lace 41 is substantially circular.
[0048] To ensure that the instep is held by the vamp 21, 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 contributes greatly to the proper support of the foot.
[0049] The invention relates more specifically to the construction of the loops 210 of this clamping system.
[0050] According to the invention, at least two loops 210, or even all of the main loops, are designed in the following manner. 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 of a sagittal plane Ps of the footwear item. The at least two loops may be arranged symmetrically with respect to the sagittal plane Ps or, alternatively, arranged in a staggered pattern. The sagittal plane Ps may be median or laterally offset. In the latter case, the tightening system is then eccentric with respect to the median sagittal plane of the shoe. In the embodiment of FIGS. 1 to 5, the sagittal plane Ps is located between the edges of the upper opening 215.
[0051] The slap 21 comprises a yoke 212 locally covering an external surface 211c of the first wall 211.
[0052] This insert 212 can be made with one of the following materials: a PolyEster (PES, PET), a PolyAmide (PA), a PolyUrethane (PU), a PolyVinyl Chloride (PVC), a natural material. Among the natural materials, one of the following materials can be used: leather, linen, hemp, wool. One can also use so-called “bio-manufactured” materials, material made from biological organisms (mycelium, bacteria, etc.). This material can also incorporate a proportion of recycled material.
[0053] This insert 212 may be a woven, non-woven or knitted textile, a film, embroidered threads.
[0054] This insert 212 is fixed to the first wall 211 by means of a first securing 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 opening su upper 215. For the purposes of the invention, 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, the part connected to the sole. In the case where the upper comprises an upper opening 215, the first connection zone 213Z is located close to the edges of the opening. This may be an area extending from the edge of the opening up to fifteen millimeters away from the edge. In the case where the upper does not comprise an upper opening 215, the upper limit of the first connection zone 213Z is advantageously at least one centimeter away from the sagittal plane and, advantageously, less than three centimeters away. This first connection zone may extend to a lower limit fifteen millimeters away from the upper limit.Thus, this first securing means 213 creates an upper connection between the first wall 211 and the insert 212. In this example, the insert 212 is also fixed to the first wall 211 by means of a second securing 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 two securing means are spaced apart by a distance d, measured between the adjacent edges of these two securing means. Between the two connection zones 213Z, 214Z, the insert 212 is not fixed to the first wall 211. In other words, the insert 212 forms a bridge between the two connection zones 213Z, 214Z.Thus, this construction makes it possible to define an interstitial space 2101 delimited by a portion of the external surface 211e of the first wall 211, a portion of an internal surface 212i of the insert 212 and the first and second securing means 213, 214. This interstitial space 2101 opens onto a front opening 2102f, on the front of the foot side, and onto a rear opening 2102r, on the heel side. This interstitial space 2101 defines a loop 210 within the meaning of the invention. A portion of the lace 41 is intended to be housed in this interstitial space 2101 by passing through the two openings 2102f, 2102r defining the entrance and the exit of the interstitial space 2101.
[0055] Generally, the loops of the prior art are made by straps folded back 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 insert 212 is assembled to the first wall 211 so as to overlap directly with the first wall 211, without folding or turning over a part of the insert 211. Thus, between the two connection zones 213Z, 214Z, the external surface 211e of the first wall 211 is very close to the internal surface 212i of the insert 212, or even almost in contact, face to face. Here, the first wall is thus covered by a layer having only the thickness of the insert 212. This design makes it possible to obtain a 210 loop particularly flat and space-saving, light, aesthetic, comfortable, simple and economical to make. In addition, because the bridge made by a part of the insert is only fixed on the external surface of the first wall, this improves the insulation of the shoe, reducing the thermal bridge at the loop and water infiltration.
[0056] To qualify the hold of the loops, the manufacturers will perform several tests to ensure that the clamping system does not deteriorate in use. For example, the applicant will conduct at least the following tests.
[0057] A tensile test consists of inserting a lace or cable into the loop. Then, a tensile force is exerted on the free ends of the lace, in a direction corresponding to the normal traction of the lacing. The threshold force necessary to cause deterioration of the loop is then measured. This threshold force must be greater than a targeted reference value.
[0058] An abrasion test consists of inserting a lace or cable into 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 back-and-forth movement of the lace at the loop, according to a determined stroke. The wear of the lace and the loop is then analyzed after a targeted number of reference cycles, a cycle being a back-and-forth or back-and-forth of the determined stroke. The loop and the lace must show acceptable normal wear, the tightening system must remain functional.
[0059] For these two tests, only a cut portion of the rod near the loop will be used.
[0060] The claimed construction is designed to comply with these tests.
[0061] According to one embodiment, the insert 212 comprises at least two layers, an outer layer 2120 and an inner layer 2121. The outer layer 2120 may be made with one of the materials described previously as the constituent material of the insert. The inner layer 2121 is made with a low-abrasive material. Such a low-abrasive material may be a PolyESter (PES), a PolyAmide (PA), a Poly-Ethylene (PE). The inner layer 2121 covers at least the area located between the two connection areas 213Z, 214Z. The inner surface of the inner layer 2121 is considered here as constituting the inner surface 212i of the insert 212. The inner layer 2121 may be a coating applied, locally or in full, to the inner surface of the outer layer 2120, for example, by spraying, impregnation or any other equivalent means.Alternatively, the inner layer 2121 may be a separate component, added and fixed on the inner surface of the outer layer 2120. For example, the added component may be a canvas, a textile, a plate, etc. For example. Furthermore, this added component can be fixed to the yoke 212 by any suitable means. This can be gluing, stitching or other. According to a non-limiting example, the internal layer 2121 is made of a PolyESter fabric glued and sewn locally on the internal surface of the yoke. This internal layer 2121 of low-abrasive material contributes to facilitating the conformity of the loop to the abrasion test as defined previously, by protecting the external layer 2120 from wear by friction generated by the sliding of the lace inside the loop. This construction consisting of having an added component makes it possible to limit, to a functional area, the use of low-abrasive material which can prove expensive. It is then possible to use a more economical material for the external layer.
[0062] According to one embodiment, the insert 212 is single-layer. In this case, this single layer can advantageously be made with a low-abrasive material.
[0063] Advantageously, the thickness of the insert, whether multi-layer or single-layer, is less than 1.5 millimeters. This makes the loop particularly flat.
[0064] According to one embodiment, the distance d between the two securing means 213, 214 is between five and ten millimeters. This makes it possible to easily pass the lace through the loop while ensuring good hold of the insert and to hold the lace well in said loops while preventing the lace from being loose in these loops.
[0065] The first and second securing means 213, 214 may be any appropriate means for ensuring the holding of the loop 210, in particular to comply with the tests as defined previously. These securing means 213, 214 may be a seam, a bond, a weld, a rivet, etc. The second securing means 214 may be different from the first securing means 213. Indeed, the tensile and abrasion resistance mainly involves the first securing means 213. The second securing means requires less holding. For example, the first securing means 213 may be a seam and the second securing means 214 may be a bond. The yoke 212 may comprise a third securing means. For example, the insert 212 can be glued to the first wall in the lower part of the vamp 21, from the sole up to and including the second connection zone 214Z.
[0066] The first securing means 213 is designed and dimensioned so that the loop remains functional after a tensile test as defined previously, with a targeted reference value of 150 Newton.
[0067] The first securing means 213 is designed and dimensioned so that the loop remains functional after an abrasion test as defined previously, with a reference mass of 1 kg and a targeted number of reference cycles of at least 2,000 cycles.
[0068] According to one embodiment, the first securing means 213 is a zigzag seam. It may also be a tight zigzag seam of the “bartack” type. These seams include stop stitches so that the seam does not come undone. Conventionally, these seams are made with PolyAmide (PA) or PolyESter (PES) threads. This type of seam is sized so that the seam is strong enough for the loop to comply with the desired requirements of the tensile and abrasion tests as described above.
[0069] According to an embodiment illustrated in [Fig.3], the seam is linear, which makes it simple and easy to produce, in particular with an automated process. The length L213 of the seam constituting the first securing means 213 is greater than five millimeters. This ensures that the structure of the tightening system 4 is maintained. The loop 210 retains good hold in use. This dimensioning allows the loop to comply with the tensile and abrasion tests according to the criteria defined previously. Advantageously, the length L213 of this seam 213 is less than ten millimeters. Furthermore, the width of the insert at the level of this first securing means is advantageously less than fifteen millimeters. This dimensioning makes it possible to have a suitable lacing path for comfortable tightening, more in line with the morphology of the instep.To obtain good strength of this seam 213, the width W213 of the seam 213 is advantageously greater than two millimeters, and preferably less than five millimeters.
[0070] According to another embodiment, the seam may not be linear in order to improve the hold of the loop. It may be a seam along a curve or in a “V”.
[0071] Figures 3 and 5 illustrate in detail the construction of loops according to an embodiment where the securing means 213, 214 are seams. In [Fig.5], the seams are symbolized by lines. The distance d separating the seams corresponds to the space between the edges of the facing seams. This construction of the loops is directly transposed to the construction of the loops of the embodiments described in Figures 6-7, 8-9 and 10.
[0072] According to one embodiment, as shown in Figures 1-2, 6 and 8, the same insert 212 is used and dimensioned to produce several contiguous loops 210. For example, the insert 212 forms a unitary assembly comprising several upper extensions 2122 connected together in the lower part of the insert. Each upper extension 2122 is designed to form a loop 210, thus covering the two connection zones 213Z, 214Z associated with the corresponding loop 210.
[0073] According to one embodiment, as shown in Figures 1 and 8, the insert 212 can extend into the lower part of the vamp 21 until, for example, it connects to a sole 3 of the footwear article 1. Thus, the insert 212 contributes to a better grip on the foot, the force recovery being transmitted more directly to the sole. This construction helps to improve the comfort of foot support.
[0074] The insert 212 may be connected at a peripheral zone of the upper surface of the damping layer 31, as illustrated in FIGS. 1 to 7. Alternatively, the insert 212 may partially or completely cover the sides of the damping layer 31 and be inserted locally between the damping layer 31 and the wear layer 32, as illustrated in FIGS. 8 to 10.
[0075] According to one embodiment, the insert 212 comprises a first securing means 213, close to a sagittal plane Ps, and is secured to the sole assembly at the junction between the upper 2 and the sole assembly 3. Outside of these two attachment zones, the insert 212 is not fixed to the first wall 211.
[0076] Alternatively, the insert 212 is fixed to the first wall 211 only near the loops 210, without extending to the sole 3. Figures 6 and 7 illustrate this alternative embodiment.
[0077] The insert 212 can also form all the loops 210 of the shoe 1. In this case, the medial and lateral parts carrying the lateral and medial upper extensions intended to form the loops 210, can be connected to each other at the front of the vamp 21.
[0078] According to one example, as shown in Figures 8 to 10, the insert and / or a portion of the first wall is covered by a protective film 216 made of Thermoplastic Polyurethane (TPU) or equivalent. This makes it possible to protect the insert from the weather, to improve the sealing and to improve the aesthetics of the slap. Thus, in these figures, the insert 212 is not visible and is hidden by the protective thread 216.
[0079] According to another embodiment, the vamp does not include an upper opening. The vamp is then continuous between its medial edge and its lateral edge, at the instep. In this example, the vamp includes at least one flexible portion 217 and, preferably extensible, in the instep area, and more particularly between the loops 210. The construction is similar to the embodiments described previously except that the upper opening 215 is closed by the flexible portion 217. This flexible portion 217 may be an added component, fixed to the first wall, as illustrated in [Fig. 9]. Alternatively, this flexible portion 217 may be a part of the first wall of the vamp, as illustrated in [Fig. 10]. In this last example, the first wall forms a flexible textile envelope 211.Here, the vamp 21 is locally reinforced by reinforcing strips 218 extending inside the envelope, from the sole 3 to a high end corresponding to the first connection zone 213Z. On one side, the reinforcing strip 218 is fixed to the sole and, at the other end, at the first connection zone 213Z, the reinforcing strip 218 is fixed to the yoke 212, as well as to . the envelope forming the first wall, thanks to the first securing means 213. Alternatively, this latter construction may not have reinforcing strips 218.
[0080] The invention is not limited to the embodiments previously described. It is also possible to combine these embodiments. The invention extends to all embodiments covered by the appended claims. References
