Abstract
Description
Technical Field
[0001] The present disclosure relates to a shoe upper. The shoe upper comprises an outer layer and an inner layer, wherein the inner layer comprises a knitted portion, and the knitted portion comprises one or more knitted functional elements.
[0002] The disclosure also relates to a corresponding shoe, in particular a sports shoe, comprising such an upper and a sole, the upper being attached to the sole. Background Art
[0003] Shoes and uppers are generally known and have a variety of purposes and usage scenarios. For example, they may be designed to provide specific benefits for athletic applications, for daily work, for leisure time, etc. In particular, in athletic applications, uppers have the potential to provide beneficial performance characteristics that can increase the overall performance of the wearer during athletic activities.
[0004] Typically, the upper provides a covering for the wearer's foot, wherein the upper comfortably accommodates and securely positions the wearer's foot relative to the sole. In addition, the upper may have a configuration that protects the foot, provides stability, and also allows for some flexibility. In addition, the upper may have a configuration that provides ventilation, thereby cooling the foot and wicking away perspiration. It can be appreciated that as the requirements for the upper in terms of functional properties become increasingly demanding, manufacturing the upper becomes increasingly difficult.
[0005] One particular concern inherent to shoe uppers is the provision of elements that allow for enhanced functional properties (such as stretch) and / or provide stability. In this context, the following exemplary prior art documents may be mentioned.
[0006] Document US7637032B2 relates to a footwear article including a textile upper member having an exterior constructed of a knitted textile material, the exterior including an area with stabilizing ribs and a second ribless area. The area with stabilizing ribs may be located, for example: along the midfoot side of the lateral side of the upper member; along the forefoot portion of the upper member; and / or along the midfoot side of the medial side of the upper member. Other footwear articles include an upper member having an exterior and interior textile element that are connected together in a stitchless manner at a foot-receiving opening of the upper member. The outer surface of the upper member may also include one or more areas with a stabilizing structure. The stitchless textile joining technology may provide a smooth, non-bulky and breathable seam that does not require a thick layer of textile material in contact with or adjacent to the wearer's foot.
[0007] Document US9986781B2 relates to a footwear article and a method for manufacturing a footwear article. The footwear may include an upper and a sole structure. The upper includes a textile element having edges, and the edges are connected together to define at least a portion of a space for accommodating a foot. The textile element may also have a first area and a second area, which have an overall structure with a variable stitch structure. The upper may also include longitudinal ribs extending along the lateral side of the foot and / or the medial side of the foot of the upper. Various warp knitting or weft knitting processes may be used to form the textile element.
[0008] Document US10834989B relates to a footwear article and a method for manufacturing the footwear article. The footwear may include an upper and a sole structure. The upper includes a textile element having edges, and the edges are connected together to define at least a portion of a space for accommodating a foot. The textile element may also have a first area and a second area, which have an overall structure with a variable stitch structure. The upper may also include longitudinal ribs extending along the lateral side of the foot and / or the medial side of the foot of the upper. Various warp knitting or weft knitting processes including circular knitting may be used to form the textile element.
[0009] Document US10669654B2 relates to an upper for an article of footwear, wherein the upper may include a knitted element, a collar region configured to form an ankle opening, and a cuff in the collar region. The cuff may be formed at least in part by a knitted element and may include a ribbed knit structure of the knitted element. On the other hand, the upper for the article of footwear may include a knitted element having a first area, the first area including a first side and a second side opposite to the first side. The first side may be formed of at least 30% more material than the second side, so that the first area is configured to be convexly curved away from the first side.
[0010] Additional prior art is disclosed in US11166517B2, US2019 / 0208862A1, US11122850B2, US6931762B1, US10745834B2, US11608575B2, US8973410B1, US10342289B2 and US11166516B2.
[0011] Although this known article of footwear or upper claims to be an improvement over the prior art known hitherto, the proposed solution still has some drawbacks when it comes to providing stability, stretch and generally improving certain functions of an upper for a shoe without compromising other functions. This is particularly detrimental in sports applications.
[0012] In addition, the manufacturing methods of the shoe uppers of the prior art are usually very complicated and labor-intensive, because they require, for example, a plurality of different parts and / or manufacturing steps. In addition, manufacturing shoe uppers of different sizes is usually accompanied by an increase in manufacturing costs.
[0013] Therefore, it can be concluded that the known solutions still do not produce optimal results. Therefore, there is still room for improvement.
[0014] Against this background, the object of the present invention is to provide an improved upper which at least partially overcomes the drawbacks of the prior art. In particular, the functional properties of the upper, such as stretch, provision of stability and / or comfort should be improved without including other properties. The overall object is to reduce the cost of providing such an upper. Summary of the invention
[0015] The above objectives are at least partially achieved by the embodiments of the present application, and other suitable aspects of the present invention are described through the overall disclosure of the present application.
[0016] In one aspect, the object is solved by an upper for a shoe, comprising: an inner layer, which is arranged near the wearer's foot when the shoe is worn; an outer layer, which is arranged on the outside of the inner layer when the shoe is worn; wherein the inner layer comprises a knitted part, which comprises one or more knitted functional elements, and wherein the outer layer at least partially covers the one or more knitted functional elements.
[0017] In this way, the present disclosure provides an improved upper. One or more knitted functional elements have the advantage of imparting functional properties to the upper in a flexible manner without compromising other properties (e.g., comfort, etc.). In addition, no openings and / or cavities may be required in the upper for accommodating any additional and / or separate functional elements. This may be attributed to the knitted functional elements included in the knitted portion.
[0018] Furthermore, the proposed knitted functional element does not cause any substantial damage to the wearer when the shoe is worn. Such damage may occur in prior art solutions, for example, through thick and / or rigid elements, etc. Furthermore, in prior art solutions, any functional element may result in an unpleasant friction surface on the wearer's foot. According to the present disclosure, this can be avoided - attributable to the arrangement of the inner layer, the knitted portion, the one or more knitted functional elements and the outer layer.
[0019] It is particularly advantageous that one or more knitted functional elements can promote stretching of the upper as part of the functional properties, for example, thereby providing compensation for changes in the length of the foot during walking.
[0020] The inner layer comprises a knitted portion comprising one or more knitted functional elements. This has the further advantage that when the shoe is worn, the one or more knitted functional elements are closer to the wearer's foot. "Closer to the foot" can be best understood as being closer to the foot than the outer layer, the outer layer being further away from the foot than the inner layer. Since the one or more knitted functional elements are closer to the foot, the one or more knitted functional elements can provide a closer and / or more direct interaction with the wearer's foot. For example, the one or more knitted functional elements can provide a specific anatomical fit. If the one or more knitted functional elements are on the outer layer of the upper, as is the case in some prior art solutions, the interaction will be less direct and therefore cannot be controlled in an enhanced manner. Overall, the knitted portion of the inner layer of the upper can provide beneficial functional properties in an improved manner.
[0021] The outer layer, which is arranged on the outer side relative to the inner layer, may provide a certain amount of movement margin, which may be beneficial during physical exercise.
[0022] As used herein, an "inner layer" may be understood as a layer that is closer to the wearer's foot than an "outer layer". In other words, when the shoe is worn, the layer structure is such that the outer layer appears first, followed by the inner layer, as seen from the outside of the upper. The upper may include additional layers. For example, the upper may include one or more other layers that are even closer to the wearer's foot than the inner layer. In addition, the upper may include one or more other layers arranged between the outer layer and the inner layer. In addition, the upper may include one or more other layers that are closer to the outside than the outer layer. In addition, it should be understood that the outer layer may include one or more knitted functional elements and / or one or more non-knitted functional elements, i.e., not necessarily knitted functional elements. In addition, the inner layer may also include one or more non-knitted functional elements.
[0023] The knitted "portion" included in the inner layer can have any spatial extension, such as length, width, height, surface area, etc. The portion can be an integral part of the inner layer. The portion can be as large as the inner layer. In other words, the portion can occupy the entire inner layer. Alternatively, the knitted portion can occupy a relatively small portion of the inner layer. It should be noted that the size of the knitted portion may not be particularly relevant to the advantages of one or more knitted functional elements described herein in order to be applicable. In addition, the size of the knitted portion may depend on the specific use of the shoe. For example, different sizes may be beneficial for different types of sports activities. In addition, the knitted portion included in the inner layer can be arranged at any position of the inner layer, such as the midfoot area of the inner layer, in particular the instep area, the medial area, the lateral area, the heel area and / or the toe area.
[0024] One or more "knitted functional elements" may refer to specific features, components or parts that are incorporated into the inner layer. Functional elements can enhance the functional properties of the upper. Functional properties as used herein may refer to one or more of the following non-exhaustive list: stretching, stability, fixation, damping, cushioning, any kind of performance characteristics, comfort, breathability, enhancement, moisture absorption, adaptability to climate, elasticity, durability and / or applicability. Functional properties may be particularly suitable for specific sports activities. As the term "element" implies, one or more knitted functional elements may be distinguishable because such elements may be distinguished from the rest of the knitted portion of the inner layer. This may be applied in any case, i.e., when one or more knitted functional elements may be formed integrally with the knitted portion, this is also true. Of course, one or more knitted functional elements may be understood in such a way that, compared with knitted fabrics, knitted portions, knitted layers, etc., they provide stronger control over functional properties.
[0025] The outer layer at least partially "covers" one or more knitted functional elements. This can be understood as making it possible for one or more knitted functional elements to be at least partially not directly visible from the outside of the upper when the shoe is worn. In other words, when the shoe is worn, from the outside of the upper, the outer layer can be at least partially arranged on top of the one or more knitted functional elements. Still, it is possible that one or more knitted functional elements can be sensed, for example by touch, etc. In addition, they can be guessed and therefore recognized from the outside by a person skilled in the art, because one or more functional elements can be provided for the outer layer to at least partially bulge.
[0026] A "wearer" may be any type of person who can wear a shoe. The term "wearer" may be used synonymously with the terms "user," "athlete," "human," etc. It should be understood that when the present disclosure refers to a wearer of a shoe, this means that the wearer wears the shoe and the upper of the shoe.
[0027] The term "knitting" may refer to any type of suitable knitting technique. In the context of the present disclosure, weft knitting or warp knitting may be used. Single-thread warp knitting techniques may be employed. As described in more detail elsewhere herein, the upper may be knitted on a circular knitting machine, preferably a small circular knitting machine. However, the upper may also be knitted on a flat knitting machine or a large circular knitting machine.
[0028] Preferably, the inner layer is a knitted inner layer. Furthermore, preferably, the outer layer is a knitted outer layer. Furthermore, preferably, the inner layer and the outer layer are knitted in an integral knitted construction. Particularly preferably, the upper is a knitted upper. The upper may be knitted in an integral knitted construction.
[0029] Vamp as described herein can be used in combination with sports shoes in particular and / or when applied to sports shoes, sports shoes such as running shoes etc. However, it should be noted that vamp can be used together with any kind of footwear, including but not limited to soccer shoes, hiking boots, sports shoes, basketball shoes, rugby shoes, baseball shoes, golf shoes, tennis shoes, cross-training shoes. In addition, vamp can be used in combination with shoes for any type of sports activities. The term sports activities should be understood to include at least one or more and / or any combination in the following non-exhaustive list: aerobics, sports exercise, running, hiking, climbing, group fitness classes, walking, cycling, yoga, football, tennis, rugby, basketball, exercise, volleyball, gymnastics, weightlifting, cross-training, baseball, softball, rugby, hockey, wrestling, squash, track and field (e.g., sprinting, long jump, high jump), cross-country skiing.
[0030] However, it has been found that the advantages of the knitted functional elements described herein are particularly pronounced when applied to shoe uppers, such as shoes used during sports activities.
[0031] In a preferred embodiment of the upper according to the present disclosure, the one or more functional elements are one or more elongated functional elements.
[0032] This has the advantage of providing a more customized fit for the upper. The elongated functional element can be more appropriately adjusted to provide an improved fit at least partially around the wearer's foot. This can help to ensure better support, stretch, stability and comfort. In addition, the foot can be more appropriately fixed in place. In addition, due to the elongated shape of the elongated functional element, functional properties, such as stability and / or stretch, can be better controlled.
[0033] The elongated shape can also provide better air circulation of the upper. For example, gaps can be provided near the elongated functional elements, which can act as air channels.
[0034] The term "slender" means that the dimension along one axis of one or more functional elements may be greater than one dimension along the remaining axes, preferably greater than two dimensions, wherein the remaining axes may be substantially perpendicular to the one axis. It should be understood that when describing dimensions herein, manufacturing tolerances must generally be considered. Although not always explicitly expressed (e.g., by using the term "substantially"), it should be understood that the elements, parts, units, shapes, etc. described herein include such manufacturing tolerances. Therefore, the dimensions described herein may vary slightly.
[0035] In a preferred embodiment of the upper according to the present disclosure, one or more functional elements define one or more protrusions.
[0036] This allows for a deeper control of the stretch and / or stability of the upper. In addition, the protrusions may provide some spacing of the inner and outer layers.
[0037] A protrusion refers to something that extends (also referred to as protrusions) from the surroundings (eg, from the knitted portion of the inner layer).
[0038] In preferred embodiments of the upper according to the present disclosure, one or more protrusions extend from the inner layer by at least 0.2 mm, preferably at least 0.4 mm, more preferably at least 0.6 mm, more preferably at least 0.8 mm, more preferably at least 1 mm, more preferably at least 1.2 mm, more preferably at least 1.4 mm, more preferably at least 1.6 mm, more preferably at least 1.8 mm, most preferably at least 2 mm, and / or extend at most 8 mm, preferably at most 6 mm, more preferably at most 5 mm, more preferably at most 4 mm, more preferably at most 3 mm, more preferably at most 2.8 mm, most preferably at most 2.5 mm.
[0039] The protrusions should not extend from the inner layer by too great an amount, as this may adversely affect the natural feel of the upper on the wearer's foot. Furthermore, this may result in a heavy shoe. The protrusions should additionally or alternatively not extend from the inner layer by too short an amount, as this may compromise the desired benefits in providing functional properties to the upper. The inventors have succeeded in achieving an optimal compromise from these opposing requirements, wherein one or more protrusions extend here by a specified amount.
[0040] In a preferred embodiment of the upper according to the present disclosure, the one or more protrusions have the shape of at least one of a rib, a ridge, a sheet or a fin.
[0041] This further increases the aforementioned advantages, as an improved anatomically stable fit can be provided by the one or more protrusions. The shapes are particularly adapted to provide an improved fit to the wearer's foot while allowing stretch. Thus, they allow an adaptive fit.
[0042] A rib may be understood as a raised, curved and / or inclined element. This may help, for example, to apply slight pressure to the wearer, so that it indicates a certain degree of stability to the wearer. In addition, this may provide a slight awareness to the wearer. However, it should be noted that the rib is designed so that it does not provide excessive uncomfortable pressure to the wearer.
[0043] In a preferred embodiment of an upper according to the present disclosure, one or more functional elements are arranged on a side of the inner layer facing away from the wearer's foot when the shoe is worn, so that the one or more functional elements are substantially sandwiched between the inner layer and the outer layer.
[0044] In this way, one or more functional elements can create a gap between the inner layer and the outer layer. This can promote air circulation, resulting in enhanced breathability. This can reduce the formation of moisture in the upper, which can be caused by, for example, rain, puddles and / or sweat. Reducing the formation of moisture is very popular with wearers. For example, breeding grounds for bacteria and / or fungi can be reduced. In addition, less moisture also leads to less friction between the foot and the upper, which reduces the formation of blisters and also reduces any irritation. In addition, odor can be improved. This in turn increases user acceptance and provides a more durable upper, as fewer washing cycles may be required.
[0045] One or more functional elements may be discretely arranged between the inner layer and the outer layer. This provides a better distribution of the one or more functional elements and may prevent the formation of annoying surfaces that would otherwise distract the wearer.
[0046] In a preferred embodiment of an upper according to the present disclosure, one or more functional elements are arranged on a side of the inner layer that faces the foot of the wearer when the shoe is worn.
[0047] This can have the advantage that a closer interaction of the functional element or elements with the wearer's foot can be established. Thus, the imparting of functional properties can be enhanced. Furthermore, a gap can then be formed on the side of the inner layer facing the wearer's foot. Furthermore, the same advantages as described in the previous embodiments in terms of air permeability, humidity, etc. are applicable to a greater extent.
[0048] The aforementioned two embodiments are understood in such a way that one or more of the one or more functional elements may be arranged on the side of the inner layer facing away from the wearer's foot when the shoe is worn, so that when the shoe is worn, one or more of the one or more functional elements are basically sandwiched between the inner layer and the outer layer, while other of the one or more functional elements may be arranged on the side of the inner layer facing the wearer's foot.
[0049] In a preferred embodiment of the upper according to the invention, one or more functional elements are additionally or alternatively arranged on the outer layer of the upper. For example, one or more functional elements may be arranged on the side of the outer layer facing away from the wearer's foot when the shoe is worn. Furthermore, one or more functional elements may be additionally or alternatively arranged on the side of the outer layer facing the wearer's foot when the shoe is worn, so that the one or more functional elements are substantially sandwiched between the inner layer and the outer layer.
[0050] In a preferred embodiment of an upper according to the present disclosure, the one or more functional elements define a scalloped shape on at least one of the lateral foot region and the medial foot region of the upper.
[0051] This allows for better control of the stretching of the upper and / or better control of the provision of stability. In particular, the scalloped shape may be adapted to follow the specific shape of the wearer's foot. Thus, the scalloped shape may mimic the natural pattern of the wearer's foot.
[0052] When mentioning one or more functional elements that limit fan-shaped shapes at this, it should be understood that not necessarily a single functional element can limit this shape. On the contrary, the major part of one or more functional elements and / or substantially all define this shape together. Therefore, any space between two adjacent functional elements can be included in the fan-shaped shape that one or more functional elements limit.
[0053] It is understood that one or more functional elements can define, for example, the shape of two separate sectors. For example, a first group of one or more functional elements can define the shape of a first sector. In addition, a second group of one or more functional elements can define the shape of a second sector. The shape of the first sector and the shape of the second sector can be substantially the same, similar or different. The shape of the first sector can be arranged on the lateral area of the foot of the upper. The shape of the second sector can be arranged on the medial area of the foot of the upper. This enhances the provision of functional properties at a dedicated position of the upper, such as at a position where stability and / or stretching is desired according to a specific use case. Thus, these functional properties can be imparted at a dedicated position of the wearer's foot.
[0054] "Fan-shaped shape" is understood so that it can include a series of curved and / or straight functional elements, each of which can be considered to have a shape similar to a blade (e.g., a fan-shaped blade). In one example, the series of functional elements can be arranged in a substantially circular segment around a central hub. The central hub can be arranged near the instep area. The circular segment is to have any angle segment, such as an angle segment of about 0° to 180°. Preferably, the substantially circular segment of the fan-shaped shape can have an angle segment of angle β in the range of 10° to 160°, more preferably from 20° to 140°, more preferably from 30° to 130°, more preferably from 40° to 120°, more preferably from 50° to 110°, more preferably from 60° to 100°, and most preferably from 70° to 95°.
[0055] In a preferred embodiment of the upper according to the present disclosure, each of the one or more functional elements is arranged at an angle relative to an adjacent functional element.
[0056] Any angle relative to adjacent functional elements is possible. The angle depends on the use of the shoe. An angle of 0° means that the functional elements are essentially parallel to each other. This angle is used to impart functional properties at a dedicated location on the wearer's foot and facilitates controlling these functional properties in a more advanced way depending on the use of the shoe.
[0057] In a preferred embodiment of an upper according to the present disclosure, the knitted portion is located in a midfoot region of the upper, particularly in a region spanning from an instep region of the upper to a sole region.
[0058] The midfoot region and the region spanning from the instep area of the upper to the sole area are found to be particularly relevant in sports activities. Therefore, this embodiment has the advantage of providing stretch and / or stability in these particularly relevant regions.
[0059] This embodiment may also be understood such that the knitted portion substantially occupies the midfoot region of the upper, particularly the region from the instep region of the upper to the sole region. The sole region of the upper as used herein may generally be arranged proximate to the bite line of the upper. It should be understood that one or more functional elements may not be disposed at the bottom of the inner layer, although such an arrangement is encompassed by the present disclosure.
[0060] In preferred embodiments of an upper according to the present disclosure, each of the one or more functional elements has an elongated axis pointing substantially from an instep region of the upper to a medial and / or lateral region of the upper.
[0061] This facilitates positioning the functional elements in a proper orientation to further support the wearer and / or provide functional properties to the upper.
[0062] In a preferred embodiment of the upper according to the present disclosure, one or more functional elements are spaced apart from each other by at least 1 mm, preferably at least 2 mm, more preferably at least 3 mm, more preferably at least 5 mm, most preferably at least 10 mm, and / or at most 50 mm, preferably at most 40 mm, more preferably at most 30 mm, more preferably at most 25 mm, more preferably at most 20 mm, more preferably at most 18 mm, most preferably at most 15 mm.
[0063] Larger spacing of one or more functional elements is advantageous for providing a more natural feel. Smaller spacing of one or more functional elements provides the possibility of providing more specialized stretching and / or stability. By the suggested spacing specified herein, the inventors have found the best compromise between these opposing requirements.
[0064] It should be understood that the spacing of one or more functional elements can vary along the length of the one or more functional elements. For example, the spacing can be smaller in the instep area of the upper. Additionally or alternatively, the spacing can be larger near the bite line of the upper.
[0065] In a preferred embodiment of the upper according to the present disclosure, the inner layer comprises a further portion, preferably a further knitted portion, wherein the further portion does not comprise the functional element, wherein the knitted portion and the further portion preferably surround the entire inner layer.
[0066] Should be understood that the knitted portion and the further portion can be integrally formed, in particular integrally knitted. For example, no seam is required to connect the knitted portion and the further portion of the inner layer.
[0067] In a preferred embodiment of an upper according to the present disclosure, one or more functional elements are configured to allow the upper to stretch in a first direction.
[0068] Such stretching may have the advantage that the inner layer may adapt to any dimensional changes imparted by the movements made by the wearer of the shoe. It may be desirable that such stretching is provided in only one direction, as this allows the shape of the upper to be controlled in substantially any other direction. The first direction may be any direction, depending on the use of the shoe.
[0069] In a preferred embodiment of an upper according to the present disclosure, one or more functional elements are configured to allow the upper to be stretched in a first direction up to a threshold, beyond which the one or more functional elements are configured to resist further stretching of the stretched upper in the first direction.
[0070] This embodiment can be used in shoes for athletic activities. For example, it can provide some safety because the upper can still secure the wearer's foot even in adverse conditions, such as when strong forces act on the upper. In one example, resistance can be understood as causing one or more functional elements to substantially resist any stretching of the stretched upper in a first direction. In other examples, one or more functional elements can substantially lock the stretched upper in the first direction.
[0071] As described elsewhere herein, the first direction along which the upper is allowed to stretch up to a threshold is preferably the direction of the course direction, beyond which the one or more functional elements are configured to resist further stretching of the stretched upper. However, in alternative examples, the one or more functional elements may prevent the upper from stretching in the direction of the course direction. Additionally or alternatively, the one or more functional elements may be configured to allow the upper to be stretched in the wale direction. As described elsewhere herein, allowing stretching and resistance by means of one or more functional elements may be achieved by employing a combination of one or more functional elements and one or more yarns, particularly fusible yarns in the remainder of the knitted portion.
[0072] As is understood, the inner layer and / or the outer layer are usually subject to a small margin of stretching and / or movement. Therefore, it cannot be excluded that, although one or more functional elements may resist further stretching of the stretched upper in the first direction, a smaller stretching of the stretched upper in the first direction may still be recognizable. This may depend on the use of the shoe and / or the forces acting on the upper, in particular in the first direction.
[0073] In a preferred embodiment of an upper according to the present disclosure, one or more functional elements are configured to allow the upper to be stretched in a second direction different from the first direction by an amount less than that in the first direction until a threshold, wherein the one or more functional elements are preferably configured to resist stretching of the upper in the second direction.
[0074] This further enhances the control of functional properties. For example, the shape of the upper in the second direction can be substantially maintained, which can provide a more secure fit of the foot.
[0075] In summary, the three embodiments described above have the advantage that an anatomically stable fit can have the additional possibility of compensating for dimensional changes, such as the length of the foot when walking.
[0076] In a preferred embodiment of the upper according to the present disclosure, the first direction is substantially parallel to the direction of the courses of the knitted portion, wherein the second direction is preferably substantially parallel to the direction of the wales of the knitted portion.
[0077] Thus, in one example, the stretching in the course direction (first direction) may be greater than the stretching in the wale direction (second direction).
[0078] In a preferred embodiment of the upper according to the present disclosure, one or more functional elements are configured to at least partially bulge the outer layer outwardly.
[0079] This may have the advantage that one or more functional elements may be sensed from the outside of the shoe.Bulging the outer layer may be understood to mean that one or more functional elements provide an embossed structure.
[0080] In some examples, one or more foils may be applied to the outer layer. This may provide enhancement, waterproofing and / or similar functions. It should be understood that these foils do not substantially affect the embossed structure, which may be attributed to the one or more functional elements bulging the outer layer. In other words, the one or more functional elements substantially retain their shape, thereby maintaining their functional properties.
[0081] In other examples, the outer layer may contain fusible yarns. After heat treatment, such fusible yarns may melt to form a film-like surface on the outer layer. One or more functional elements of the knitted portion of the inner layer may still be sensed by the embossing effect provided on the film-like surface of the outer layer.
[0082] In a preferred embodiment of an upper according to the present disclosure, one or more functional elements extend over the total length of a row of the knitted portion, wherein the row is preferably arranged so as to pass through the instep area and the medial and / or lateral foot area - adjacent to the sole area of the upper.
[0083] This facilitates providing one or more functional elements which are relatively long and uninterrupted. Thus, functional properties can be imparted over a greater length. Furthermore, control over these properties can be improved.
[0084] The position of one or more functional elements depends on the use of the shoe. For example, it has been found that one or more functional elements are particularly useful in the midfoot region to prevent twisting and provide stability for the wearer's foot. This may be desirable for running. In other sports, one or more functional elements should be primarily located in the medial area of the foot (e.g., in the medial forefoot region and / or the medial heel region of the foot) to provide wear resistance and / or durability. For example, this may be important when the shoe is performing sliding motions. This may be desirable for tennis and / or sports in which similar impacts are expected.
[0085] In one example, one or more functional elements extend over the entire length of a course of the knitted portion, wherein the course is preferably arranged across the instep area and the medial and / or lateral foot areas - adjacent to the bite line of the upper.
[0086] In a preferred embodiment of the upper according to the present disclosure, one or more functional elements comprise one or more segments, each segment extending over the length of a row of the knitted part, said length being at least 10%, preferably at least 20%, more preferably at least 30%, most preferably at least 50%, and / or at most 80%, preferably at most 70%, more preferably at most 60% of the total length of the row of the knitted part, wherein the row of the knitted part is preferably arranged so as to pass through the instep area and the medial and / or lateral foot areas - near the sole area of the upper.
[0087] With this embodiment, one or more sections can provide greater flexibility to impart desired functional properties at specific locations on the wearer's foot. Thus, control over the functional properties can also be increased.
[0088] One or more sections should not be too short and / or too long. With the lengths specified here, an optimum balance between the different requirements can be achieved.
[0089] In a preferred embodiment of the upper according to the present disclosure, one or more functional elements are knitted integrally with the knitted portion.
[0090] This facilitates the manufacturing process, since the number of required manufacturing steps can thereby be reduced. Furthermore, the number of components of the upper can be reduced (e.g., compared to a case where one or more functional elements are separate components). It is conceivable that one or more functional elements replace any kind of component used in the prior art, such as a reinforcing element, foam, laces, adhesive strips and / or the like, since the one or more functional elements can provide a similar function. This can make the entire manufacturing process quite cost-effective.
[0091] In addition, since there are no further interfering components, elements and / or parts on the knitted portion of the inner layer, user acceptance can be enhanced. In addition, when one or more functional elements are knitted integrally with the knitted portion, it is not necessary to provide a seam on the knitted portion, the inner layer or even the upper.
[0092] In a preferred embodiment of the upper according to the present disclosure, one or more functional elements are formed by a stitch structure that is different from the stitch structure of the rest of the knitted part, wherein one or more functional elements are preferably formed by a tuck structure.
[0093] Using a different stitch structure for one or more functional elements compared to the rest of the knitted part has the advantage of giving these functional elements specific functional properties.
[0094] The tuck stitch allows providing a fairly durable one or more functional elements which can maintain substantially any shape, such as a three-dimensional shape. This is true even after multiple uses of the upper. This can be achieved by the finely interlocked tuck stitch which helps maintain the shape of the one or more functional elements.
[0095] The use of a tuck stitch as used herein provides a rather simplified way of creating any kind of three-dimensional shape in the knitted portion of the inner layer. The tuck stitch has the advantage of increasing the bulk of the fabric, which is useful for providing functional properties.
[0096] As an alternative to a tuck stitch, the stitch stitch can be kept suspended on each needle during knitting (e.g. by using floats, which are long strands of yarn that pass through the back of the fabric). By this, a build-up of material can be achieved, which can result in a three-dimensional shape, such as a ridge. This can be similar to providing a tuck stitch.
[0097] In a preferred embodiment of the upper according to the present disclosure, one or more functional elements are formed by a tuck structure, which includes at least 1, preferably at least 2, more preferably at least 3, more preferably at least 4, more preferably at least 5, more preferably at least 6, more preferably at least 7, and most preferably at least 8 stitch organization rows, and / or at most 25, preferably at most 20, more preferably at most 18, more preferably at most 16, and most preferably at most 15 stitch group rows.
[0098] Increasing the number of rows (i.e. lines) of the tuck stitch has the advantage of increasing the accumulation of material. Thus, for example, the height of one or more functional elements can be increased. This allows the functional properties to be imparted to be controlled in an improved manner. As will be appreciated by a person skilled in the art, the number of rows depends on the use of the shoe.
[0099] Increasing the number of courses may also increase the weight of the knitted material. For example, a smaller number of courses may be desirable in certain areas of the upper where less pronounced functional properties are required.
[0100] Without wishing to be bound by theory, the inventors believe that the number of tuck organizations described herein provides an optimal compromise between these conflicting requirements.
[0101] In a preferred embodiment of the upper according to the present disclosure, the one or more functional elements include one or more of elastic yarn, fusible yarn, especially low melting temperature fusible yarn, polyester yarn, fluffy yarn, and silicon yarn, wherein the one or more functional elements are preferably composed of one or more of elastic yarn, fusible yarn, especially low melting temperature fusible yarn, polyester yarn, fluffy yarn, silicon yarn, and monofilament yarn.
[0102] This is conducive to providing specific characteristics for one or more functional elements according to the use of the shoe. For example, when elastic yarn is used, stretchability can be enhanced. In addition, when fusible yarn (for example, low melting temperature fusible yarn / TPU yarn) is used, rigid functional elements can be provided. These rigid functional elements are basically unable to stretch due to their rigidity, and can be used to provide a fairly elastic upper. In addition, when high-resistance yarn is used, wear-resistant functional elements can be provided. Examples of high-resistance yarns can be: (high tenacity) polyester yarn, nylon yarn, aramid yarn, polyethylene yarn, acrylic yarn, viscose rayon yarn. In addition, when fluffy yarn or fluffy yarn is used, more significant functional elements, such as functional elements with greater height, can be provided. This can provide a more significant three-dimensional effect.
[0103] In a preferred embodiment of the upper according to the present disclosure, the outer layer covers substantially all of the one or more functional elements of the knitted portion, wherein the outer layer preferably covers the inner layer.
[0104] This has the advantage that one or more functional elements may not be directly visible from the outside. Thus, the appearance of the upper can be improved. Furthermore, one or more functional elements can thereby be protected from environmental influences. For example, the outer layer can be made of a yarn that provides more durability and / or more wear resistance than the inner layer, so as to protect the inner layer. The inner layer can be obtained with a yarn to impart the desired functional properties without necessarily requiring a yarn that provides high durability and / or high wear resistance.
[0105] Covering the inner layer with an outer layer has the advantage that the overall manufacturing process can be enhanced.
[0106] In a preferred embodiment of the shoe upper according to the present disclosure, the outer layer comprises one or more of polyester yarn, blended yarn, fusible yarn (especially low melting temperature fusible yarn). In addition, hygroscopic yarn can be used.
[0107] Yarns may be continuous strands of fibers, filaments, or materials that are twisted or spun together to form a long cohesive thread-like structure.
[0108] Note that any of the yarns described herein may also be used in the inner layer.
[0109] In a preferred embodiment of the upper according to the present disclosure, the outer layer does not comprise functional elements.
[0110] This may be advantageous in cases where sufficient stability and / or stretch and / or any kind of functional properties are already provided by the inner layer. In this way, the structure of the outer layer is simplified. Therefore, less manufacturing effort is required.
[0111] In a preferred embodiment of the upper according to the present disclosure, the inner layer and the outer layer are connected to each other in a seamless manner, preferably at a foot-receiving opening of the upper.
[0112] This has the advantage that the inner layer and the outer layer can be integrally knitted together at the foot-receiving opening. Thus, no seams are visible. However, if desired, a seam or a seam-like structure can be provided. It should be noted that the foot-receiving opening of the upper can be understood as the collar area of the upper.
[0113] In a preferred embodiment of the upper according to the present disclosure, the inner layer and the outer layer form a two-layer assembly.
[0114] This double layer assembly may also be referred to as a sock-in-sock structure. Thus, the outer layer may surround the inner layer.
[0115] The detailed description of the invention describes the manufacture of the upper after the inner layer and the outer layer are knitted.
[0116] In a preferred embodiment of the upper according to the present disclosure, the upper is manufactured on a flat knitting machine or on a circular knitting machine, preferably on a circular knitting machine.
[0117] Small circular knitting machines can also be used. The machine can have one, two or even more than two needle beds.
[0118] Circular knitting machines may have the advantage of providing a tubular construction without the need for one or more seams. Circular knitting machines are generally faster than flat knitting machines, making them more suitable for high volume production.
[0119] Flat knitting machines may have the advantage that they can produce a wide variety of fabric types. In addition, flat knitting machines may have the advantage of providing specific custom fits.
[0120] When it is mentioned herein that the upper is manufactured on a flat knitting machine or a circular knitting machine, this means that the inner layer as well as the outer layer are manufactured on such a knitting machine.
[0121] In preferred embodiments of an upper according to the present disclosure, the one or more functional elements each define a substantially closed shape.
[0122] A closed shape means that one or more functional elements may not have openings etc. For example, such openings may be present in the form of holes or the like. In one example, one or more functional elements do not have through holes.
[0123] In another aspect of the present disclosure, these objects are solved by a shoe, in particular a sports shoe, comprising: an upper according to any of the embodiments described herein; and a sole attached to the knitted upper.
[0124] It goes without saying that the technical properties, advantages and improvements over the prior art shown or described for the shoe upper also apply to the shoe, in particular the sports shoe, and vice versa. BRIEF DESCRIPTION OF THE DRAWINGS

[0141] Only some possible embodiments of the present invention are described in detail below. However, the present invention is not limited to these, and many other embodiments are applicable without departing from the scope of the present invention. The presented embodiments can be modified in various ways and can be combined with each other as long as they are compatible, and certain features can be omitted as long as they do not seem necessary. In particular, the disclosed embodiments can be modified by combining certain features of one embodiment with one or more features of another embodiment.
[0142] It should be understood that not all features of the described aspects / embodiments must be present to achieve the technical advantages provided by the present disclosure, which is defined by the subject matter of the claims. The disclosed aspects / embodiments may be modified by combining certain features of one aspect / embodiment with one or more features of another aspect / embodiment. Specifically, the skilled person will understand that the features and / or functional elements of one aspect / embodiment may be combined with technically compatible features and / or functional elements of any other aspect / embodiment of the present disclosure, as long as the resulting combination falls within the definition of the present disclosure.
[0143] Although the following embodiments are mainly described with reference to uppers for shoes, especially sports shoes, those skilled in the art will recognize that the disclosure according to the present invention can be equally applied to a number of different technical fields and / or usage situations.
[0144] Throughout the drawings and description, like reference numerals represent like elements. For the sake of clarity and conciseness, certain aspects of components or steps of certain embodiments are presented without excessive detail, where such details would be apparent to one skilled in the art based on the teachings herein, and / or where such details would obscure an understanding of more relevant aspects of the embodiments.
[0145] As understood by those skilled in the art and / or to avoid redundancy, reference is also made to the explanations in the previous sections, which also apply to the detailed description below. In addition, for the sake of brevity and clarity, not all features, parts, elements, aspects, components and / or steps are clearly indicated by reference numerals. This is particularly applicable to those skilled in the art who recognize that these features, parts, elements, aspects, components and / or steps exist in multiple forms. One example may be a knitted functional element.
[0146] definition
[0147] Unless otherwise indicated, the term "substantially" or "essentially" used in this context may be understood as to a great extent or a significant extent, or for the most part, or essentially. In particular, manufacturing tolerances are included in this term.
[0148] The term "and / or" only describes the association relationship of associated objects and indicates that there may be three relationships. For example, A and / or B can represent three situations: A exists independently, A and B exist at the same time, and B exists independently. In addition, the character " / " in the present disclosure generally indicates that the previous and next associated objects form an "or" relationship.
[0149] For the sake of simplicity, one or more “knitted functional elements” are sometimes referred to herein as one or more “functional elements.” In the case of non-knitted functional elements, this is explicitly indicated.
[0150] The term "bite line" as used in this disclosure may refer to a line along the intersection of an upper and a sole.
[0151] The term "course" as used in the present disclosure may refer to a row of predominantly horizontal needle loops produced by adjacent needles during the same knitting cycle (in a standing fabric when knitting). In some examples, the term "course" may be used synonymously with the term "row".
[0152] The term "wale" as used in this disclosure may refer to a main vertical column of interlaced loops, which are usually produced by the same needles, which are knitted in consecutive (not necessarily complete) knitting cycles. A wale begins to be produced when an empty needle begins to knit.
[0153] The term "tuck stitch" as used in the present disclosure may refer to the formation of a stitch when a needle that is already holding a stitch receives an additional stitch. The additional stitch is tucked behind the held stitch. A fabric with a tuck stitch may have lower elasticity in the wale direction but increased elasticity in the course direction. This may be the case because the tuck stitch essentially pulls down the held stitches and spreads them out.
[0154] Description of the drawings
[0155] Figure 1 An exemplary upper 2 for a shoe is shown according to an embodiment of the present disclosure.
[0156] The upper 2 includes an inner layer 10 ( Figure 1 Not shown, but in Figure 3 The inner layer 10 is arranged near the foot of the wearer when the shoe is worn. The upper 2 also includes an outer layer 30, which is arranged on the outside of the inner layer 10 when the shoe is worn. The inner layer 10 includes a knitted portion 20 (in Figure 1 However, the knitted portion 20 is Figure 1 The knitted portion 20 includes one or more knitted functional elements 25 (in Figure 1 , however, one or more knitted functional elements 25 are covered by an outer layer 30 ). The outer layer 30 at least partially covers one or more knitted functional elements 25 .
[0157] As from Figure 1 As can be understood in the embodiment of the present invention, the one or more functional elements 25 are one or more elongated functional elements 25. Specifically, the one or more functional elements 25 define one or more protrusions 25. The one or more protrusions 25 may extend at least 0.2 mm and / or at most 8 mm from the inner layer 10. The one or more protrusions 25 have the shape of at least one of a rib, a ridge, a thin sheet or a fin. This can be understood as each of the one or more protrusions 25 having such a shape. Of course, each of the one or more protrusions 25 can have different shapes. In other words, not all of the one or more protrusions 25 need to have the same shape.
[0158] Figure 1 The one or more functional elements 25 are arranged on a side of the inner layer 10 that faces away from the wearer's foot when the shoe is worn. Thus, the one or more functional elements 25 are substantially sandwiched between the inner layer 10 and the outer layer 30. Figure 1 As shown, one or more functional elements 25 are discretely disposed on the inner layer 10 and are located between the outer layer 30 and the inner layer 10 .
[0159] Alternatively or additionally, one or more functional elements 25 may be arranged on the side of the inner layer 10 that faces the foot of the wearer when the shoe is worn.
[0160] Knitted portion 20 (in Figure 1 In the embodiment, the knitted portion 20 is covered by the outer layer 30) is located at the midfoot region 8 of the upper 2, in particular, at the region spanning from the instep region 7 of the upper 2 to the sole region 9. Figure 1 As can be seen in FIG. 2 , the knitted portion 20 and the one or more functional elements 25 end in the sole area 9 , which is arranged close to the bite line of the upper 2 .
[0161] Furthermore, each of the one or more functional elements 25 has an elongated axis that is directed substantially from the instep region 7 of the upper 2 toward the medial side region 5 (eg, Figure 4 ) and / or the lateral foot area 6.
[0162] Furthermore, one or more functional elements 25 are spaced apart from one another by at least 1 mm and / or at most 50 mm.
[0163] Furthermore, the inner layer 10 includes an additional portion 40 (in Figure 1 In the indication, however, another part 40 in Figure 1 The knitted portion 20 and the additional portion 40 preferably surround the entire inner layer 10.
[0164] Furthermore, one or more functional elements 25 are configured to at least partially bulge the outer layer 30 of the upper 2. Figure 1 The functional element or elements 25 are thus indirectly visible due to their three-dimensional height.
[0165] like Figure 1 As shown, one or more functional elements 25 can extend over the entire length of a row of knitted portion 20. Figure 1 In the embodiment of the present invention, the horizontal row can be arranged to pass through the instep area 7 and the lateral foot area 6 - near the sole area 9 of the upper 2 (i.e., close to the bite line of the upper 2). Similarly, the horizontal row can be arranged to pass through the instep area 7 and the medial foot area 5 of the upper 2. Of course, the horizontal row can also pass through the instep area 7 and the medial foot area 5 and the lateral foot area 6 of the upper 2.
[0166] As will be appreciated, the extension, position and / or arrangement of the one or more functional elements 25 depends on the use of the shoe, as adapted to different requirements. Depending on the extension, position and / or arrangement of the one or more functional elements 25, different advantages can be achieved. These different advantages are highlighted, for example, by the different requirements described for running (twisting in the midfoot region should be prevented and stability should be provided) and tennis (for example, wear resistance and / or durability should be provided in the medial area of the foot, as the shoe may slide).
[0167] One or more functional elements 25 may include one or more segments (e.g. Fig. 6E Each segment extends over the length of a row of the knitted portion 20 for at least 10% and / or at most 80% of the total length of the row of the knitted portion 20. As previously mentioned, the rows of the knitted portion 20 may be arranged to pass through the instep region 7 and the medial foot region 5 (e.g. Figure 4 ) and / or the lateral area 6 of the foot - near the sole area 9 of the upper 2 (i.e., close to the bite line of the upper 2).
[0168] One or more functional elements 25 may be knitted integrally with the knitted portion 20. This may significantly reduce manufacturing costs, since substantially no separate components, such as reinforcing elements, foams, laces and / or the like, need be provided.
[0169] like Figure 1 As further shown, the outer layer 30 covers substantially all of the one or more functional elements 25 of the knitted portion 20. Furthermore, the outer layer 30 may cover the inner layer 10.
[0170] like Figure 1 As shown, the outer layer 30 may not include knitted functional elements 25, such as the functional elements included by the knitted portion 20 of the inner layer 10. This may be the case, because sufficient stability, stretch and / or any kind of functional properties may already be provided by the inner layer 10.
[0171] Furthermore, as can be deduced from the knitting sequence described further below, one or more functional elements 25 may each define a substantially closed shape.
[0172] It should be noted that whenever a component, feature, layer, element, and / or the like is described as "knitted" or "knitted" in this disclosure, this may allow for the derivation of distinctive features formed by interlocking yarns or loops. These loops are also referred to as stitches and may be formed by one or more yarns or threads. Knitted fabrics may have the advantage of including a degree of stretchability compared to other types of fabrics, such as woven fabrics, so that the upper may be optimally adjusted to the shape of the foot and provide the necessary support to the wearer.
[0173] Figure 2 An exemplary upper 2 for a shoe according to another embodiment of the present disclosure is shown. Figure 3 An exemplary upper 2 for a shoe according to another embodiment of the present disclosure is shown. These embodiments are similar to all other embodiments described herein, and they may include one or more features described in the context of other embodiments. For brevity, only additional features are described.
[0174] exist Figure 2 In the embodiment, one or more foils 31 are applied to the outer layer 30. This provides reinforcement, waterproofing and / or similar effects. Figure 2 As can be seen in the figure, the one or more foils 31 are smoothly aligned with the outer layer 30 and these foils 31 do not substantially affect the embossed structure provided by the one or more functional elements 25 that bulge the outer layer 30. Thus, the one or more functional elements 25 substantially retain their shape and can still impart their beneficial functional properties to the upper.
[0175] like Figure 3 As shown, the outer layer 30 may alternatively or additionally include fusible yarns. After heat treatment, such yarns may fuse to form a membrane-like surface 31 on the outer layer 30. Also in this example, one or more functional elements 25 on the inner layer 10 may still be sensed by the embossing effect provided on the membrane-like surface 31 of the outer layer 30.
[0176] Figure 4 An exemplary illustrative upper 2 for a shoe according to another embodiment of the present disclosure is shown. This embodiment is similar to and applicable to all other embodiments described herein, and for the sake of brevity, only additional features are described.
[0177] As can be seen, one or more functional elements 25 define a scalloped shape on the medial side area 5 of the upper 2. It also includes one or more functional elements 25 defining a scalloped shape on the lateral side area 6 of the upper 2 (e.g., Figure 1 , Figure 2 and Figure 3 ). It is also possible that one or more functional elements 25 define two sectors separated from each other, for example, one on the medial side of the foot region 5 of the upper 2 and one on the lateral side of the foot region 6 of the upper 2 .
[0178] Furthermore, each of the one or more functional elements 25 is arranged at an angle α relative to the adjacent functional element 25. This is achieved by placing Figure 4 The two dotted lines on the right-hand side of the two functional elements 25 are indicated by way of example.
[0179] In addition, Figure 4As shown, the one or more functional elements 25 defining the sectors can be arranged in substantially circular segments around a central hub. The circular segments can have any angular segments having an angle β of any suitable size. For example, the circular segments can have an angular segment with an angle β of about 0° to 180°, as described elsewhere herein. Angle β is Figure 4 exemplarily shown by two dotted lines placed on the rightmost knitted functional element 25 and the leftmost knitted functional element 25. The substantially circular segment of the sector shape can have an angular segment with an angle β in the range of 10° to 160°, the angle β being more preferably from 20° to 140°, more preferably from 30° to 130°, more preferably from 40° to 120°, more preferably from 50° to 110°, more preferably from 60° to 100°, most preferably from 70° to 95°. Figure 4 In a specific example of , the angle may be about 85° to 87°, in particular 86°. However, as will be appreciated, any kind of angle β may be encompassed by the present disclosure, and the angle β is not limited to Figure 4 For example, Figure 4 The angle β is only used to illustrate.
[0180] One or more functional elements 25 may be configured to allow the upper 2 to stretch in a first direction X (eg, Figure 4 Such stretching of the upper 2 in the first direction X may be provided up to a threshold value, beyond which the one or more functional elements 25 are configured to resist further stretching of the stretched upper 2 in the first direction X. In addition, the one or more functional elements 25 may be configured to allow the upper 2 to stretch in a second direction Y different from the first direction X (e.g., Figure 4 Preferably, the one or more functional elements 25 are configured to resist stretching of the upper 2 in the second direction Y. The first direction X may be substantially parallel to the direction of the courses of the knitted portion 20, and the second direction Y may be substantially parallel to the direction of the wales of the knitted portion 20.
[0181] It should be noted that the knitted portion 20 may include any number of functional elements 25. For example, the knitted portion 20 may include at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more functional elements, and / or at most 50, 40, 30, 20, 15, 10 or fewer functional elements 25.
[0182] As described elsewhere herein, the size of the knitted portion 20 may not be particularly relevant to the advantages of one or more knitted functional elements 25 described herein to apply. The knitted portion 20 may substantially occupy the entire inner layer 10. In other examples, the knitted portion 20 may occupy up to 95%, preferably up to 90%, more preferably up to 80%, more preferably up to 70%, more preferably up to 60%, more preferably up to 50%, more preferably up to 40% of the entire inner layer 10, and / or the knitted portion 20 may occupy at least 5%, preferably at least 10%, more preferably at least 20%, more preferably at least 30%, more preferably at least 40% of the entire inner layer 10.
[0183] Figure 5A , Figure 5B , Figure 5C , Figure 5D , Figure 5E and Fig. 5F An exemplary schematic upper 2 for a shoe according to another embodiment of the present disclosure is shown. The described embodiments are similar to and applicable to all other embodiments described herein, and for the sake of brevity only, all features of the aforementioned embodiments are not repeated. In addition, when an area of the upper 2, such as the medial area 5 of the upper 2, the lateral area 6 of the upper 2, the instep area 7 of the upper 2, and / or the midfoot area 8 of the upper 2 is described as including one or more functional elements 25, it may also be the case that another area of the upper 2 may additionally or alternatively include these one or more functional elements 25. In addition, for the sake of brevity only, not all functional elements 25 are indicated by reference numerals.
[0184] Figure 5A 2 is an embodiment of the upper 2 shown in three different perspectives. When used in sports such as tennis and / or similar sports where similar impacts are expected, Figure 5A The upper 2 shown in FIG. 2 may be particularly useful.
[0185] Figure 5A The top picture shows the upper 2 from a view of the outside 6 of the foot. Figure 5A The middle picture shows the upper 2 from a top view. Figure 5A The bottom picture shows the upper 2 from the view of the inner side 5 of the foot. The upper 2 comprises an inner layer (not shown) comprising a knitted portion 20 (not shown) comprising one or more knitted functional elements 25. Figure 5AIn the top picture of the upper 2, one or more knitted functional elements 25 are shown as being arranged in the toe area 4, as well as in the lateral area 6 of the foot. One or more knitted functional elements 25 are not arranged in the heel area 30. In addition, one or more knitted functional elements 25 are not arranged in the instep area 7 of the upper 2, and / or one or more knitted functional elements 25 may not extend to the instep area 7 of the upper. As shown in FIG. Figure 5A As can be seen in the middle picture, one or more knitted functional elements 25 are arranged in the toe area 4, the medial area 5 and the lateral area 6 of the upper 2. Figure 5A As can be seen from the bottom picture, one or more knitted functional elements 25 are arranged in the toe area 4, the medial area 5, and one or more knitted functional elements 25 extend toward the heel area 30. In addition, one or more knitted functional elements 25 extend toward the instep area 7 of the upper 2. Therefore, one or more knitted functional elements 25 substantially cover the entire medial area 5 of the upper 2.
[0186] like Figure 5A As shown, one or more functional elements 25 are primarily located on the medial area 5 of the foot to provide wear resistance and / or durability. This may be important, for example, when the shoe is used for sliding movements. This may be desirable for tennis and / or sports where similar impacts are expected.
[0187] like Figure 5A As shown, one or more knitted functional elements 25 are arranged in a substantially continuous manner. In addition, one or more knitted functional elements 25 can be arranged substantially equidistant relative to each other. However, one or more knitted functional elements 25 can also be arranged into one or more groups, wherein at least one of the one or more groups includes one or more knitted functional elements 25 that are substantially discontinuous. In addition, any two knitted functional elements 25 can have a space different from that between two other knitted functional elements 25. In addition, intervals can be provided between one or more groups. It should be understood that in such intervals, knitted functional elements 25 (such as Figure 5C , Figure 5D and Figure 5E shown).
[0188] exist Figure 5A In an embodiment, the knitted functional element 25 is knitted with a high resistance yarn as described elsewhere herein. This has the advantage that a wear-resistant functional element 25 can be provided, which can reduce wear caused by the external environment. Non-exhaustive examples of useful sports applications of such an upper 2 can be tennis, badminton, basketball, handball, fencing, etc. In particular, sliding and / or resistance areas can be provided on the upper 2, which can protect the wearer's foot 1 (in Fig. 5FIn addition, the shoe upper 2 can be prevented from being worn when strongly contacting with the surface of the field or an opponent during sports activities.
[0189] Figure 5B 2 is an embodiment of the upper 2 shown in three different perspectives. When used in sports such as basketball and / or similar sports in which similar impacts are expected, Figure 5B The upper 2 shown in FIG. 2 may be particularly useful.
[0190] Figure 5B The top picture shows the upper 2 from a view of the outside 6 of the foot. Figure 5B The middle picture shows the upper 2 from a top view. Figure 5B The bottom picture shows the upper 2 from a view of the inside 5 of the foot. Figure 5B An embodiment similar to Figure 5A , and only the differences are described. It can be seen that one or more knitted functional elements 25 are arranged in the toe area 4, the medial area 5 and the lateral area 6. Figure 5A In contrast, one or more knitted functional elements 25 are arranged both on the medial area 5 and on the lateral area 6 of the upper 2, almost up to the heel area 30. Figure 5B As can be seen in the middle picture, one or more knitted functional elements 25 are substantially symmetrical relative to a vertical plane, which is arranged parallel to the axis from the heel 30 to the toe 4 of the upper 2.
[0191] Figure 5C Two different embodiments of the upper 2 are shown. Figure 5C The left side of the two pictures shows another embodiment. Figure 5C The right side of the embodiment is shown in two pictures. The top picture of each of the two embodiments shows the upper 2 in the most expanded state. The bottom picture of each of the two embodiments shows the upper 2 in the most compressed state. This is indicated by the dotted line in the bottom picture of each of the two embodiments, which is similar to the shape of the upper 2 before compression.
[0192] In each embodiment, the upper 2 includes an inner layer (not shown) including a knitted portion 20 (not shown) including one or more knitted functional elements 25. Figure 5C In each embodiment of the present invention, one or more knitted functional elements 25 are shown to be arranged in the region from at least the instep region 7 of the upper 2 to the sole region. Figure 5C As shown in the embodiment on the right side of the embodiment, one or more functional elements 25 are arranged in a first group in the midfoot region of the upper 2. In addition, one or more functional elements 25 are arranged in a second group in the area from the heel 30 toward the vicinity of the Achilles tendon.
[0193] The first group and the second group, or any group as described herein generally, can be combined to provide additional functional enhancement. For example, these groups can form a network of one or more knitting functional elements 25, which work in coordination to provide desired effects and / or functions. For example, these groups can be provided with interactive lines between the groups, which can help realize additional functions. For example, the interactive lines can have higher rigidity or higher elasticity. Therefore, these groups can be combined to contribute greater functionality as the sum of each individual group alone.
[0194] like Figure 5C As shown in the embodiment on the left, one or more knitted functional elements 25 are arranged at least in the area from the instep area 7 of the upper 2 to the sole area (with Figure 5C The embodiment on the right is the same). Therefore, one or more knitted functional elements 25 can be basically distributed on the midfoot area of the upper 2. Figure 5C In both embodiments, by such an arrangement of one or more knitted functional elements 25, a good balance between two conflicting requirements can be achieved: on one side, sufficient freedom of movement of the front forefoot area of the upper 2 relative to the rearfoot area can be achieved. This also facilitates the torsion capability of the upper 2. On the other side, sufficient limitation of the movement and / or stabilization of the midfoot area of the upper 2 can be achieved.
[0195] exist Figure 5C In the embodiment of the present invention, the knitted functional element 25 is knitted with elastic yarns as described elsewhere herein. This has the advantage of providing a tight, form-fitting upper. This may be particularly useful when combined with a laceless construction. Another advantage is that the foot may be immobilized during dynamic movements. Non-exhaustive examples of useful sports applications of such an upper 2 may be football, rugby, running, training, etc. A further advantage is that the upper 2 may provide a compression fit and is suitable for sports activities involving extended durations.
[0196] Figure 5D Detailed Description of the Invention The embodiment of the shoe upper 2 is shown in three different viewing angles. Figure 5D The top picture shows the upper 2 from a view of the inside 5 of the foot. Figure 5D The middle picture shows the upper 2 from a top view. Figure 5D The bottom picture shows the upper 2 from a view of the outside 6 of the foot.
[0197] The upper 2 includes an inner layer (not shown), the inner layer includes a knitted portion 20 (not shown), and the knitted portion includes one or more knitted functional elements 25. It can be seen that one or more knitted functional elements 25 can be arranged in different areas of the upper 2. Figure 5DAs can be seen from the middle picture, two groups of one or more knitted functional elements 25 are present. One group of one or more knitted functional elements 25 is arranged in the instep area 7 of the upper 2. Another group of one or more knitted functional elements 25 is arranged in the area near the Achilles tendon. The heel area 30 of the sole close to the upper 2 may not have one or more knitted functional elements 25.
[0198] exist Figure 5D In the embodiment of the present invention, the knitted functional element 25 is knitted with fluffy yarns as described elsewhere herein. This has the advantage that the volume of the functional element 25 can be increased. This can provide comfortable padding in the collar and U-shaped throat area of the shoe upper 2. This can, for example, reduce shoelace pressure. Non-exhaustive examples of useful sports applications of this upper 2 can be any type of court sports. Instead of using a complete foam padding block, adding fluffy yarns can allow sweat absorption and faster drying, reducing the extra weight of the shoe when soaked. This is useful for any sport, such as tennis, especially when exposed to adverse weather conditions (e.g., high temperature, humidity, etc.). In addition, the upper 2 can have the advantage that it can provide insulation for outdoor activities.
[0199] Figure 5E Detailed Description of the Invention An embodiment of an upper 2 is shown in three different views. Figure 5E The top picture shows the upper 2 from a view of the inside 5 of the foot. Figure 5E The middle picture shows the upper 2 from a top view. Figure 5E The bottom picture shows the upper 2 from a view of the outside 6 of the foot. Figure 5E An embodiment similar to Figure 5D It can be seen that one or more knitted functional elements 25 are arranged in a manner similar to Figure 5D One or more knitted functional elements 25 may be arranged in a first group, which is arranged in the instep area 7 of the upper 2. The first group may have a pointed shape viewed from the heel area 30 to the toe area 4 of the upper 2. In addition, one or more knitted functional elements 25 may be arranged in a second group, which is arranged in the ankle area 3 of the upper 2.
[0200] Fig. 5F is an embodiment of the upper 2, shown in a perspective view in the middle right side. Fig. 5FThe bottom image and two top images of the figure depict the arrangement of one or more functional elements 25 relative to the wearer's foot 1 at three different viewing angles. The upper 2 includes an inner layer (not shown), the inner layer includes a knitted portion 20 (not shown), and the knitted portion includes one or more knitted functional elements 25. It can be seen that the one or more knitted functional elements 25 are arranged in at least one full side area of the upper 2. In addition, the one or more knitted functional elements 25 surround the sole area of the upper 2, such as Fig. 5F As shown in the bottom picture and the two top pictures. Fig. 5F In the embodiment of the present invention, a fusible yarn as described elsewhere herein is used to knit the knitted functional element 25. This has the advantage that a relatively elastic yarn is used, which exhibits reduced or almost no stretch. This provides stability, which is useful for many sports applications, such as sports applications involving side cuts. The upper 2 provides a secure accommodation for the foot 1. This improves stability, which is particularly useful for court sports and various other sports applications, such as fencing, wrestling and / or training.
[0201] In any of the embodiments described herein, the upper 2 can be manufactured on a flat knitting machine or a circular knitting machine. A distinction can be made between a flat knitting machine and a circular knitting machine. In a flat knitting machine, a yarn feeder delivers yarn back and forth along a row of needles. In a circular knitting machine, the needles are arranged in a circular manner, and the thread feed accordingly takes place in a circular motion along one or more circular rows (also referred to herein as courses) of needles that may be located on a needle cylinder.
[0202] The advantage of using a small circular knitting machine is that most or all of the upper 2 of the shoe can be made directly to the correct size and shape, so that no further cutting steps are required. However, as described elsewhere herein, the upper 2 can also be produced on a flat knitting machine or a large circular knitting machine. When a large circular knitting machine is used, the upper 2 can be cut out of the tubular textile after the textile has been produced by the machine.
[0203] It should be noted that small circular knitting machines differ from large circular knitting machines in terms of their size, capacity and / or the type of products they produce. A skilled person can easily distinguish between small circular knitting machines and large circular knitting machines.
[0204] Compared to large circular knitting machines, small circular knitting machines are usually compact and have a smaller diameter. Such small circular knitting machines can be used to produce tubular fabrics, such as socks, gloves, hats, etc. Large circular knitting machines can have larger sizes and can be used to produce wide fabrics. In some examples, large circular knitting machines can have a greater number of needles. This facilitates the production of wider fabrics.
[0205] Note that the inner layer 10 and / or the outer layer 30 may comprise a single-layer fabric or a double-layer fabric. The double-layer fabric may be obtained by using a double needle bed knitting machine. The machine has two needle beds, allowing two layers of fabric to be knitted simultaneously. The layers of the double-layer fabric may be interconnected by certain stitch patterns, forming a stable and coherent fabric without visible seams on either side. Such a double-layer fabric may be provided by a flat knitting machine as well as a circular knitting machine. When the double-layer fabric is viewed from the side, the needles in the two rows of needles may, for example, be substantially at right angles to each other. This may enable the manufacture of a finer structure or fabric. The use of two rows of needles may allow the manufacture of a single-layer or double-layer weft knitted fabric.
[0206] In the embodiment described herein, the manufacture of the upper 2 (particularly the knitted inner layer 10 (in Figure 3 The manufacture of the upper 2 after the outer layer 30 is formed (indicated in the figure) and the outer layer 30 can be as follows: the outer layer 30 is covered on the inner layer 10. Alternatively, the inner layer 10 is inserted into the outer layer 30. Subsequently, the two layers are connected at their respective free ends. This joining can be performed, for example, by connecting, sewing, welding or gluing. The outer layer 30 and the inner layer 10 can have the shape of an elongated hollow knitted structure, such as a cylinder, after knitting. Therefore, they can include an opening at their respective free ends, which is also closed by connecting the free ends. The opening is preferably joined in the longitudinal direction on the bottom of the layers 10, 30, so that the seam joining the free ends can be completely hidden by the sole. Therefore, due to the joining, the free ends may no longer be considered as "free ends" after joining.
[0207] Fig. 6A An exemplary knitting sequence for producing a knitted portion 20 including one or more knitted functional elements 25 according to an embodiment of the present disclosure is shown. This knitting sequence is applicable to all other embodiments described herein, and may be used in addition or alternatively to any other knitting sequence described herein. Fig. 6A Also shown are the row direction C and the wale direction W, which also applies to Figure 6B , Figure 6C , Fig.6D and Fig. 6E .
[0208] As generally described herein, one or more functional elements 25 may be formed by stitches 22a, 22b, 22c, 22d, 22e, 22f, 22g, 22h (generally 22a-22h) that are different from the stitches 21a, 21b (in the knitted portion 20) of the rest of the knitted portion 20. Fig. 6A Only two of these stitches are indicated by way of example in the figure). Preferably, one or more functional elements 25 are formed by tuck stitches 22a-22h.
[0209] One or more functional elements 25 may be formed by tuck stitches 22a-22h comprising at least one, preferably at least two, preferably at least three, preferably at least four, preferably at least five, preferably at least six, preferably at least seven, preferably at least eight stitch stitch rows, and / or at most 25, preferably at most 20, preferably at most 18, preferably at most 16, preferably at most 15 stitch stitch rows. Fig. 6A In FIG. 1 , a first group 22 including 8 rows of tuck stitches 22a-22h and a second group 22′ including 8 rows of tuck stitches 22a-22h are shown. The first group 22 and the second group 22′ are combined to form a knitted functional element 25.
[0210] Increasing the number of tuck stitch rows can increase the height of the functional element 25. In addition, the stiffness provided by the functional element 25 can also be increased. In addition, with a greater number of tuck stitch rows, more material will be gathered. This helps to create the shape of one or more functional elements 25 and thus impart functional properties.
[0211] The rows of normal stitch weave 21b can reduce the strain and / or tension on the needles of the knitting machine. This can thereby prevent needle breakage. In addition, this can relax the knitted structure. This is particularly useful between the two sets of 22, 22' tuck weave rows. However, if Figure 1 As shown, this can also be used in Fig. 6A At the boundary of the group 22 shown by the horizontal row of normal stitch organization 21a.
[0212] Figure 6B An exemplary knitting sequence for creating a knitted portion 20 including one or more knitted functional elements 25 according to another embodiment of the present disclosure is shown. This knitting sequence is applicable to all other embodiments described herein, and may be used in addition or alternatively to any other knitting sequence described herein.
[0213] according to Figure 6B The functional element 25 comprises four groups 22, 22', 22", 22'', each group comprising four horizontal rows of tuck structures 22a, 22b, 22c, 22d. Each of the four groups 22, 22', 22", 22'' is separated from the adjacent group by the horizontal rows of normal stitch structures 21b, 21c, 21d. Fig. 6A The same advantages as those for the horizontal rows of the normal stitch organization 21b arranged in Figure 6B The normal stitch organization 21b, 21c, 21d horizontal rows.
[0214] Due to the provision of multiple sets of tuck stitch courses, this knitting sequence provides an increased width of the functional element 25. This will result in an enlarged area of the surface of the functional element 25. Thus, the top surface of the functional element 25 can be made wider. This in turn can increase the width of the functional element 25. For example, this can be wider than 1 cm and as described elsewhere herein.
[0215] Figure 6C An exemplary knitting sequence for creating a knitted portion 20 including one or more knitted functional elements 25 according to another embodiment of the present disclosure is shown. This knitting sequence is applicable to all other embodiments described herein, and may be used in addition or alternatively to any other knitting sequence described herein.
[0216] according to Figure 6C The functional element 25 comprises two groups 22, 22', each group comprising four horizontal rows of tuck structures 22a, 22b, 22c, 22d. Each of the two groups 22, 22' is separated from the adjacent group 22, 22' by a horizontal row of normal stitch structure 21b. Fig. 6A The same advantages as those for the horizontal rows of the normal stitch organization 21b arranged in Fig.6D The normal stitch organization 21b in the horizontal rows.
[0217] exist Figure 6C In the embodiment of the invention, the arrangement of the tuck stitch rows of the first group 22 and the second group 22' has been changed relative to each other in order to achieve a special visual effect. In particular, small discrete portions of the functional element 25 are arranged in the row direction C, these discrete portions of the functional element 25 being separated by gaps (in Figure 6C The plurality of layers are separated by a break in the longitudinal direction W (represented by the letter "g" in FIG. 1 ) and / or a break in the longitudinal direction W.
[0218] This may contribute to the overall appearance of the functional element 25. Thus, the functional element 25 may achieve different visual effects.
[0219] Fig.6D An exemplary knitting sequence for creating a knitted portion 20 including one or more knitted functional elements 25 according to another embodiment of the present disclosure is shown. This knitting sequence is applicable to all other embodiments described herein, and may be used in addition or alternatively to any other knitting sequence described herein.
[0220] according to Fig.6D The functional element 25 comprises two groups 22, 22', each group comprising four horizontal rows of tuck structures 22a, 22b, 22c, 22d. Each of the two groups 22, 22' is separated from the adjacent group 22, 22' by a horizontal row of normal stitch structure 21b. Fig. 6AThe same advantages as those for the horizontal rows of the normal stitch organization 21b arranged in Fig.6D The normal stitch organization 21b in the horizontal rows.
[0221] Each of the two groups 22, 22' spans the entire width of the fabric. This may represent a long, uninterrupted functional element 25. In other words, the functional element 25 extends over the entire length of a course of the knitted portion 20.
[0222] Fig. 6E An exemplary knitting sequence for creating a knitted portion 20 including one or more knitted functional elements 25 according to another embodiment of the present disclosure is shown. This knitting sequence is applicable to all other embodiments described herein, and may be used in addition or alternatively to any other knitting sequence described herein.
[0223] according to Fig. 6E The functional element 25 comprises several sections in the knitting sequence. Each section comprises two groups 22, 22', each group comprising four rows of tuck stitches 22a, 22b, 22c, 22d (only for the sake of clarity, the rows of tuck stitches are not provided with reference numerals, but they are obvious to a person skilled in the art when referring to any of the aforementioned figures). Each of the two groups 22, 22' in each section is separated from the adjacent group 22, 22' by a row of normal stitch stitches 21b. Fig. 6A The same advantages as those for the horizontal rows of the normal stitch organization 21a are also applicable to Fig.6D The normal stitch organization 21b in the horizontal rows.
[0224] The several sections are arranged in a staggered manner. This can allow functional properties to be imparted according to the desired needs of the shoe's usage.
[0225] although Figures 6A to 6E The description of partially relates to one functional element 25 , but the same features and advantages apply to any of the remaining ones of the one or more functional elements 25 .
[0226] In any of the embodiments described herein, one or more functional elements 25 may include one or more of elastic yarns, fusible yarns, particularly low melting temperature fusible yarns, polyester yarns, bulky yarns, and silicon yarns.
