Description

[0001] This application is a divisional application of Chinese invention patent application filed on December 10, 2020, with application number 202011451872.1 and invention title "Knitted Upper with Integrated Eyelet". Technical Field

[0002] This invention relates to a knitted shoe upper with an integral eyelet and a corresponding manufacturing method. Background Technology

[0003] Despite numerous alternative attempts, shoelaces remain one of the most convenient ways to secure shoes to a wearer's foot. Eyelets are needed on the shoe upper to guide the laces and allow the shoe to be properly tightened. Typically, eyelets are either (stamped) holes in the upper material or additional elements attached to the upper material, such as lugs.

[0004] Providing eyelets in this manner requires additional manufacturing steps, whether punching or attaching additional elements. For example, US 2018 / 0110283 A1 discloses an upper comprising a knitted component. In addition to intermeshing loops, the knitted component may include one or more structures forming eyelets. This structure may include a first end, a second end, and a central portion. The first and second ends may be secured to the surface of the knitted component. In some embodiments, for example, a fusible material may be included in the yarn forming the surface and / or structure. When heated, the fusible material may be activated (e.g., at least partially melted) and then cooled, thereby securing the first and / or second ends. Alternatively or additionally, the securing of the first and / or second ends may be enhanced in another suitable manner, such as by sewing, by using adhesives, by fastening, by mechanical clamping, etc.

[0005] WO 2019 / 001676 A1 relates to a shoe, particularly an athletic shoe, comprising an upper, wherein the upper is at least partially composed of a knitted fabric, and wherein the upper has a plurality of loops for threading through shoelaces to allow the shoe to be tightened at the wearer's foot by the shoelaces. To provide a simple and efficient possibility for individually adjusting the tightness or lacing of the shoe at the wearer's foot, at least a portion of the loops are composed of a knitted fabric, wherein the loops have a tubular shape that forms a channel for the shoelaces.

[0006] US 2018 / 0255877 A1 relates to a footwear article including a sole, an upper, and a reconfigurable fastening system. The upper is attached to the sole and includes an inner plate and an outer plate. A plurality of eyelets are provided on the inner and outer plates. Each eyelet includes a pair of openings provided in the upper. The plurality of eyelets also includes at least one elongated member passing through the pair of openings of each eyelet. The elongated member includes a series of first portions or unexposed portions provided on the inner surface of the upper, and a series of second portions or exposed portions provided on the outer surface of the upper. A fastener or lace can selectively pass through one of the plurality of eyelets, wherein the fastener can be threaded between the second portion of the elongated member and the outer surface of the upper.

[0007] Other prior art is disclosed in CN 203986311 U, US 2019 / 0037966 A1, US 2008 / 0110049 A1 and US 2017 / 0208900A1.

[0008] Therefore, the object of the present invention is to provide an upper configured to use shoelaces, which can be manufactured with fewer manufacturing steps compared to the prior art. Summary of the Invention

[0009] This objective is achieved by the upper of the present invention. The upper according to the invention includes a knitted component comprising a plurality of integrally knitted lines of loops, the lines of loops comprising a set of continuous strips, wherein each strip in the set of continuous strips comprises a plurality of continuous loops, the plurality of continuous loops being interlooped with the loops of adjacent strips and not interlooped with the loops of strips not included in the set, and wherein the set of continuous strips forms at least a portion of an eyelet configured to receive shoelaces.

[0010] In the context of this invention, a “belt” can be a row or a line, and the knitted part can be weft-knitted or warp-knitted.

[0011] This invention allows eyelets to be formed in the shoe upper without additional manufacturing steps. The eyelets are configured as continuous loops that interlock within each other in each loop and also interlock with adjacent loops of adjacent loops in the same group, but not with loops that are not part of the continuous group. This group of continuous loops forms an integral lug within the knitted component for receiving shoelaces. No additional manufacturing steps are required to provide the eyelets.

[0012] This set of continuous tapes can be knitted using a partial knitting method. In partial knitting, a set of loops is formed by knitting, while other loops are held on the needle in a non-knitted position. Thus, these loops are held or left in place, while the surrounding needles (selected by the knitting program) are generating loops. Partial knitting can be performed using a knitting machine with appropriate programming. Partial knitting allows the raised eyelets of the upper to be provided directly as an integral structure during knitting by providing additional loops of tape that do not belong to this set of continuous tapes. In this way, partial knitting allows for a curved shape that protrudes from the surface of the knitted part for the eyelets.

[0013] The strip can be longitudinal (wale).

[0014] The first strip in the continuous group and the first adjacent strip not included in the group can form a first hole in the knitted component, wherein the last strip in the continuous group and the second adjacent strip not included in the group can form a second hole in the knitted component, and wherein the first and second holes can be configured such that shoelaces can pass through these two holes. The holes are advantageously formed during the knitting process. Additional manufacturing steps such as punching can be avoided.

[0015] The first band in this set of continuous bands may extend from a first end of the eyelet to a second end of the eyelet and may include a first number of loops. The second band, not included in this set, may include all loops between the loops adjacent to the first end of the eyelet and the loops adjacent to the second end of the eyelet, and may include a second number of loops, wherein the first number may be greater than the second number. This allows the looped band forming the eyelet to protrude from the surface of the knitted component, facilitating lacing. The eyelet may protrude like a lug but is integrally formed within the knitted component.

[0016] The width of the eyelet can be between 5 mm and 15 mm. Preferably, the width of the eyelet is between 7 mm and 10 mm. The set of continuous straps can include 2 to 10 straps. The inventors have found that such a width is optimal for threading shoelaces, while also being sufficiently stable and tear-resistant.

[0017] The strips in this set of continuous coiled strips can have a length between 10 mm and 30 mm. Preferably, the strips in this set of continuous coiled strips can have a length between 15 mm and 25 mm. Each strip in this set of continuous coiled strips can contain 15 to 25 coils. The inventors have found that such a length is optimal for threading through conventional shoelaces.

[0018] The number of loops in the strip between the first and last loops of this set of continuous loop tapes can be higher than the number of loops in the first and last strips. This provides a more stable and reinforced eyelet, which retains its shape better due to the solid knit structure. Furthermore, this ensures a pleasing appearance and avoids uneven edges. It also results in a more rounded eyelet. A half-open knit can be used at the edge of the eyelet.

[0019] The knitted component may include at least one fusible yarn in the area of ​​the continuous loop tape. This provides abrasion resistance and reduces eyelet deformation. The at least one fusible yarn may be used alone or in combination with other non-fusible yarns such as polyester or elastic yarns. In this case, the fusible yarn may typically be knitted together with non-fusible or elastic yarns, or it may be added, for example, towards the inner surface, so that the appearance of the knitted component is unaffected by the presence of the fusible yarn.

[0020] The fusible yarn can be located solely within the band of this set of continuous loops. This allows for sufficient stiffness and stability to the eyelet while maintaining the overall stretchability of the upper. Alternatively, the fusible yarn can be positioned in the area of ​​the lace bar (the area around the eyelet) to specifically provide support for that area. The lace bar can be defined by multiple sets of continuous bands, as described herein, on the outer and inner sides of the instep area of ​​the upper. Preferably, these sets and the eyelets formed by them are aligned.

[0021] The fusible yarn can be selected from polyester yarn, polyamide yarn, or urethane-based yarn. The fusible yarn can be made from TPU, polyamide (PA6 + PA66), polyester (where stretching has a significant impact during spinning), and paraffin wax. Preferably, the fusible yarn used is a low-melting-point yarn, i.e., a yarn having a melting temperature preferably between 50°C and 10°C. Alternatively, the fusible yarn can be selected from polyamide-based or fusible polyester-based yarns.

[0022] The upper may include an inner knitted layer and an outer knitted layer in a one-piece knitted structure, wherein the inner and outer layers are connected at least in the collar area of ​​the upper, and wherein the outer layer is overlaid on the inner layer, or wherein the inner layer is inserted into the outer layer. This increases the stability and comfort of the upper. Additionally, the two layers can have different functions. For example, the inner layer may be made of soft, moisture-wicking yarn, while the outer layer may be made of abrasion-resistant yarn.

[0023] The inner layer may also provide one or more shoelace loops, which can pass through corresponding openings in the outer layer at locations corresponding to multiple eyelets on the outer layer. One or more shoelace loops can be knitted into the inner layer. The shoelace loops can be knitted in a similar manner to the eyelets on the outer layer, but knitted into the inner layer. One or more shoelace loops can pass through corresponding eyelets on the outer layer and can be configured to receive shoelaces. The shoelaces can then be received by the shoelace loops.

[0024] The length of the lace loops can be chosen to be longer than the length of the multiple eyelets. In addition to the new shoe design, this arrangement provides a more even distribution of tension than traditional lacing systems because it distributes the tension across the entire upper. This force distribution also provides increased tensile strength while reducing pressure on the wearer's feet, offering added comfort. The arrangement further increases the flexibility in choosing the direction in which this lacing system is laid out.

[0025] This set of continuous coiled bands can be located on the outer layer. This allows for easy threading through the shoelaces.

[0026] These two layers can overlap in the area of ​​the continuous coil band. In this way, the lower layer can be used as cushioning below the eyelet.

[0027] These two layers may not be connected in the area of ​​the continuous coil band. In this area, the two layers may overlap slightly to allow relative movement when the shoelaces are tightened.

[0028] These two layers can overlap in the instep area of ​​the shoe upper, and can also remain separate in the instep area. This allows for a better fit, as the inner layer or sock wraps around and holds the foot, while the outer layer or sock can be adjusted independently via laces. This helps the outer sock maintain its shape better. The shoe upper can be a sock-within-a-sock structure, where these two layers define the inner and outer socks. Preferably, these two layers are formed using a small circular knitting machine; specifically, each layer is a single-knit layer.

[0029] The knitted component may include at least one elastic yarn in the area of ​​the set of continuous loops. The elastic yarn helps the eyelet acquire and maintain the desired shape. The elastic yarn may be used alternatively or additionally with fusible and / or non-fusible yarns. If only the elastic yarn is added to the eyelet, the cost that is typically expensive for fusible yarns can be saved. The inventors recognized that elastic yarn is sufficient to maintain the shape of the eyelet.

[0030] The elastic yarn can be located only in the belt of this set of continuous loops. Therefore, the elastic yarn can provide particular stability to the eyelet. The elastic yarn can be placed alternatively or additionally entirely along the lace bar of the upper.

[0031] Elastic yarns can be more elastic than the other yarn in a knitted part.

[0032] The present invention also relates to a shoe comprising an upper as described herein according to the invention and a sole structure attached to the upper.

[0033] The present invention also relates to a method of manufacturing a shoe upper, comprising the steps of: providing a knitted component; providing the knitted component with a plurality of integrally knitted loop tapes, the loop tapes comprising a set of continuous tapes such that each tape in the set of continuous tapes comprises a plurality of continuous loops, the plurality of continuous loops being interlocked with loops of adjacent tapes and not interlocked with loops of tapes not included in the set; and forming the set of continuous tapes as at least a portion of an eyelet configured to receive shoelaces.

[0034] The aforementioned advantages of the shoe upper according to the invention can also be achieved in the corresponding manufacturing method, and will not be repeated here. This also applies to the following embodiments of the method. Further advantages will be mentioned if necessary.

[0035] The method may also include the step of knitting the set of continuous strips by partial knitting.

[0036] In this method, the strips can be vertical.

[0037] The method may further include the following steps: forming a first hole in a knitted component using a first strip from the set of continuous strips and a first adjacent strip not included in the set; forming a second hole in the knitted component using the last strip from the set of continuous strips and a second adjacent strip not included in the set; and configuring the first hole and the second hole such that a shoelace can pass through the two holes.

[0038] In this method, a first strip in the set of continuous strips may extend from a first end of the eyelet to a second end of the eyelet and may include a first number of coils, and a second strip not included in the set may include all coils between the coils adjacent to the first end of the eyelet and the coils adjacent to the second end of the eyelet, and may include a second number of coils, wherein the first number may be greater than the second number.

[0039] In this method, the eyelet can have a width between 5 mm and 15 mm.

[0040] In this method, the set of continuous bands may include 4 to 10 bands.

[0041] In this method, the strip in the set of continuous coil strips can have a length between 10 mm and 30 mm.

[0042] In this method, each strip in the continuous coil strip may contain 15 to 25 coils.

[0043] In this method, the number of coils in the strip between the first and last strips of the continuous coil strip can be greater than the number of coils in the first and last strips.

[0044] The method may further include the step of arranging at least one fusible yarn in the region of the set of continuous coil strips.

[0045] The method may also include the step of arranging fusible yarns only in the tape of the set of continuous coil tapes.

[0046] In this method, the fusible yarn can be selected from polyester yarn, polyamide yarn, or urethane-based yarn. The yarn may include thermoplastic polyurethane (TPU).

[0047] The method may further include the following steps: providing an inner knitted layer and an outer knitted layer in an integral knitted structure; joining the inner and outer layers at least in the collar area of ​​the shoe upper to form the shoe upper; and overlaying the outer layer onto the inner layer, or inserting the inner layer into the outer layer, to form the shoe upper. Joining the two layers in the collar area can be done integrally during the knitting of the two layers, thus the transition from the inner to the outer layer is seamless. Alternatively, the two layers can be joined in another area, such as the toe area or the sole area, for example, by stitching.

[0048] The method may also include the step of forming the set of continuous coil strips on the outer layer.

[0049] In this method, the two layers can overlap in the region of the set of continuous coil strips.

[0050] In this method, the two layers may not be connected in the region of the continuous coil strip.

[0051] In this method, the two layers can overlap in the instep area of ​​the shoe upper, but are not connected in the instep area.

[0052] The method may further include the step of providing at least one elastic yarn in the area of ​​the set of continuous loops. As mentioned above, the fusible yarn can be omitted in this case. If there is no fusible yarn in the eyelet area, then in this manufacturing method, the step of placing a pin in each lace loop during heat setting, as will be described below, is not required. Heat setting can still be performed to release torque on the yarn generated during knitting and stabilize the shape of the upper, but the specific heat setting step for fusing the fusible yarn to the eyelet is not required.

[0053] This method may include a heat-setting step for the shoe upper. Heat setting can be performed at temperatures ranging from 50°C to 130°C, a range that covers almost all relevant materials without damaging any part of them. More specifically, heat setting can be performed at a temperature of approximately 100°C, and the heat setting can be carried out in a steam oven.

[0054] The method may further include the step of arranging elastic yarns only in the tape of the set of continuous coil tapes.

[0055] In this method, the elastic yarn can be more elastic than the other yarn in the knitted part.

[0056] The method may further include the step of using a small circular knitting machine to provide the knitted parts.

[0057] The method may also include the steps of placing a pin within the eyelet formed by the set of continuous coils and holding the pin within the eyelet during heat setting of the upper. This may be advantageous if the eyelet is provided with fusible yarn to stabilize and shape the eyelet during heat setting.

[0058] The method may also include the step of heat-setting the shoe upper.

[0059] The present invention also relates to shoe uppers obtained by the methods of the present invention as described herein. Attached Figure Description

[0074] Figure 1A and Figure 1B An embodiment of the shoe upper 10 according to the present invention is shown. In this embodiment, the shoe upper 10 is made of two sock-like layers 11 and 12, which are joined at the collar area 13 of the respective sock-like layers 11 and 12. Figure 1A and Figure 1B In this embodiment, the two layers are knitted together as a single piece on a small circular knitting machine, i.e., as an integral knitted structure. The two socks 11 and 12 are made as a continuous, preferably single-jersey, cylindrical knitted fabric. Typically, in the context of this invention, the upper can have a different number of layers, for example, a single layer. In the case of two layers, these layers can also be manufactured separately and then joined together, for example, by joining, sewing, welding, gluing, etc. Furthermore, instead of a small circular knitting machine, a medium or large circular knitting machine or a flat knitting machine can be used. This machine can have one, two, or even more than two needle beds. Typically, in the context of this invention, weft knitting or warp knitting can be used. Suitable knitting yarns can be based on synthetic materials such as polyester, but natural yarns such as cotton can also be used.

[0075] Back Figure 1A and Figure 1BIn this embodiment, layer 11 is the outer layer of upper 10, and layer 12 is the inner layer of upper 10. The outer layer 11 covers the inner layer 12, and the two layers are joined at their respective free ends 13 and 14, for example, by joining, sewing, welding, or gluing. Since socks 11 and 12 are made cylindrical, they include openings at their respective free ends 13 and 14, which are also closed by this process. The openings are preferably longitudinal on the bottom of the layers (socks) so that the seam can be completely hidden by the sole. In the final upper 10, the joined free ends will be arranged in the sole area of ​​upper 10 and will therefore be invisible. The inner layer 12 is inserted into the outer layer 11. Alternatively, the outer layer 11 can cover the inner layer 12. Covering the inner layer 12 with the outer layer 11 can be done on a shoe last.

[0076] Figure 1A and Figure 1B In this embodiment, the outer layer 11 is a knitted component of the upper 10. In this embodiment, the knitted component constitutes the majority of the upper 10. In other embodiments, the knitted component may be smaller and constitute only a portion of the upper 10. Other parts of the upper may be made of different materials, such as leather, synthetic leather, fabric, non-woven fabric, mesh, etc.

[0077] The knitted component, namely the outer layer 11, comprises multiple integrally knitted loop tapes. Typically, knitted fabrics are obtained by interlooping at least one yarn to form loop tapes. In the context of this invention, the tapes can be in rows or columns. The knitted component 11 comprises a set of continuous tapes, wherein each tape in the set comprises multiple continuous loops, which interloop with the loops of adjacent tapes but not with the loops of tapes not included in the set. Therefore, the loops of the tapes in this set are connected only to loops within the same tape or to adjacent loops of adjacent tapes within the set, and not to loops of tapes not included in the set. Thus, the set of continuous tapes forms at least a portion of the eyelet, which is configured to receive the shoelace 16. Figure 1A and Figure 1B In one embodiment, three of these eyelets are indicated by reference numeral 15. Figure 1A The shoe upper 10 without shoelaces is shown, wherein in Figure 1B In the middle, shoelace 16 has already passed through eyelet 15.

[0078] exist Figure 1A and Figure 1B In the example, the continuous strip is obtained through partial knitting. In partial knitting, a set of loops is formed by knitting, while other loops remain in the non-knitted position. Partial knitting can be performed using a knitting machine with appropriate programming. Partial knitting allows the eyelets of the shoe upper to be provided as a whole structure directly during knitting.

[0079] Figure 2A and Figure 2B It shows the relationship with Figure 1A and Figure 1B A similar embodiment of the upper 10. The upper 10 is a sock-in-sock construction, wherein... Figure 2A and Figure 2B In one embodiment, one sock is already placed inside the other, specifically by placing the inner sock inside the outer sock. For example... Figure 1B As shown, the openings at the free ends of the inner and outer socks are closed by the longitudinal seam 21 on the bottom of the sock (i.e., in the sole area).

[0080] Figure 3A and Figure 3B Structural details of the eyelet 15 according to the invention are shown, wherein Figure 3A The front of the single-knitted component 11 is shown. Figure 3B The back of the single-knit component 11 is shown, where two areas of the eyelet 15 on the front are highlighted by rectangles 31. (See image) Figure 3A As shown, the eyelet 15 is formed of looped bands. Three of these bands are exemplarily indicated by reference numeral 31. The loops of these bands 31 are interlocked with the loops of each other, and also interlocked with the loops of adjacent bands 31 belonging to the same group of continuous bands. The looped bands constituting one eyelet 15 form a group of continuous bands. The knitted component 11 also includes other looped bands not included in this group. Three of these bands are exemplarily indicated by reference numeral 32. Bands 31 in the group of continuous looped bands constituting one eyelet 15 are not interlocked with bands 32. Thus, two holes are formed on the side of the eyelet 15 through which shoelaces can pass.

[0081] To provide stability to the eyelet 15, fusible yarns can be incorporated into the continuous loop tape constituting the eyelet 15. To activate the fusible yarns, the upper 10 is heat-set by placing it in a steam oven at, for example, a temperature of approximately 100°C. To stabilize the eyelet during heat setting, a pin can be placed within the eyelet 15 formed by the continuous loop tape. This... Figure 4A As shown, three pins are exemplary, indicated by reference numeral 41. Pins 41 can be made of metal or any other material capable of resisting heat during heat setting, particularly of the fusible yarn, in the shoe upper. In a preferred embodiment, pins 41 have a length of 52 mm and a diameter of 5 mm.

[0082] Figure 4B Depicting Figure 4A Alternative embodiments of the pin are shown. In this example, the pin has a different length and is disposed in a corresponding retainer 43.

[0083] Figure 4CAnother embodiment of the currently preferred pin 41 is depicted. In this example, the pin 41 is made of a soft material. The soft material allows each pin 41 (or finger) to be flexible and bendable, easily inserted into and adapted to each eyelet. The pin 41 is long enough to pass through two sets of lace holes (on the outer and inner sides). In an exemplary embodiment, five pins are connected by a common base 44. Thus, for example, only two such structures are needed for a pair of shoes. Of course, in other embodiments, a different number of pins 41 may be provided on the common base.

[0084] exist Figure 4D In another embodiment shown, the comb-like or spider-like structure 42 is used to stabilize the eyelet 15 during heat setting. Figure 5A , Figure 5B and Figure 5C This structure is described in more detail in [the text], where Figure 5A The main view is shown. Figure 5B A side view is shown. Figure 5C An oblique view is shown. Structure 42 includes a body 51 from which pins 41 protrude. This structure allows multiple pins 41 to be inserted into corresponding eyelets 15 simultaneously and in a single step. Structure 42 can be obtained using a 3D printing process.

[0085] Figure 6A and Figure 6B An embodiment of the upper 10 according to the invention is shown, wherein elastic yarn has been added to the eyelets 15. In this embodiment, the eyelets 15 do not include fusible yarn. Even when the upper 10 is heat-set to stabilize its shape, the elastic yarn is sufficient to stabilize the eyelets. In this case, a specific heat-setting step for melting the fusible yarn on the eyelets 15 is not required. Moreover, it is not necessary to place pins in the eyelets 15 during heat setting.

[0086] Figure 7A and Figure 7B Details of an eyelet 15 of the shoe upper according to the invention are shown. The set of continuous looped bands constituting an eyelet 15 includes a first band 71. The loops of this band are interlocked with the corresponding loops of the adjacent bands in the set, but not with the loops of the adjacent bands 72 not included in the set. This forms a hole 73 through which the shoelace can pass. The eyelet 15 includes similar holes on the opposite sides. Figure 7A and Figure 7B The shoe upper described herein is based on the sock-within-a-sock structure as described above. The outer layer 11 covers the inner layer 12. Figure 7A In an exemplary embodiment, the outer layer 11 includes a plurality of openings through which the inner layer 12 can be seen.

[0087] Figure 8A , 8BImages 8C and 8D illustrate embodiments of a shoe 80 according to the invention. The shoe includes an upper 10 as described herein and a sole structure 81 connected to the upper 10.

[0088] The sole structure 81 is attached to the upper 10 by directly injecting PU sole material onto the upper 10. In the context of this invention, other methods of attaching the sole 81 to the upper 10 are of course possible.

[0089] The upper 10 includes a knitted element comprising a plurality of eyelets 15 formed by a set of loops comprising a set of continuous tapes, wherein each tape in the set of continuous tapes comprises a plurality of continuous loops, the plurality of continuous loops being interlocked with the loops of adjacent tapes but not interlocked with the loops of tapes not included in the set. Figure 8D As shown, eyelet 15 is configured to receive shoelace 16.

[0090] Figure 9 An exemplary knitting sequence for obtaining eyelets 15 in a knitted component as described herein is shown. The knitting sequence can be provided as a suitable procedure to a knitting machine, and the eyelets 15 can be obtained by partial knitting.

[0091] Figure 10A An exemplary embodiment of a shoe according to the invention is shown, wherein the shoe 100 may be implemented as a double-layer structure having an inner layer 12 and an outer layer 11 knitted together integrally. The inner layer 12 is provided with a plurality of shoelace loops 101 knitted to the inner layer 12. The shoelace loops 101 pass through openings 102 in the outer layer 11 at the locations of a plurality of eyelets 15.

[0092] Figure 10B A side view of a shoe 100 is shown, which can be implemented as a double-layer structure having an inner layer 12 and an outer layer 11 knitted together integrally. The outer layer 12 may include a plurality of eyelets 15. A plurality of shoelace loops ( Figure 10B (Not shown) Knitted into the inner layer 12 and through the corresponding openings of the outer layer 11 at the locations 102 of the plurality of eyelets 15.

[0093] Figure 10C An illustration shows an exemplary knitted structure that can be used in the collar area of ​​a shoe. The knitted yarn, which can be elastic or inelastic, is arranged in a square pattern 103. However, other suitable knitted patterns can also be applied.
