Description

Technical area

The present invention relates to the field of shoe technology. In particular, the invention relates to a running shoe with an adaptive upper material.

State of the art

Running shoes, for example sports shoes, tennis shoes, hiking shoes or casual shoes, are typically held on the wearer's foot using laces or Velcro. Velcro fasteners have the disadvantage that although they can be easily closed and opened, they lose their original holding effect after a short time. Shoelaces, on the other hand, have the disadvantage that they often lead to unpleasant pressure points and the knots can come loose while running, which is particularly undesirable during sport. Furthermore, the total weight of a running shoe is becoming increasingly important, especially in the area of competitive sports. The use of both Velcro and laces requires additional components and materials, which increase the overall weight of the running shoe.

Shoes that do not have lacing are known in the prior art. For example, it is known to provide a shoe with an elastic textile upper, which is highly compressed when unworn. As soon as the wearer puts the shoe over the foot, the elastic upper material is stretched and pressed against the foot. Shoes known in the art are in US 2016/174660 A1 , WO 201 6/055642 A1 , US 2016/174661 A1 , US 2012/204448 A1 and US 2010/269369 A1 known.

Presentation of the invention

However, with the known shoes without laces, the hold of the foot in the shoe is significantly reduced compared to common shoes with laces. While a lower level of support is tolerable in casual shoes due to the wearer's slow walking speeds, the risk of injury during sports increases significantly with such shoes. There are no known running shoes without closures that offer good support during sports and can therefore adequately replace the common laced versions. In particular, with lace-free running shoes, it is a problem to keep the wearer's foot above the shoe sole in such a way that the foot cannot slip beyond the periphery of the shoe sole, so that twisting is prevented even when walking at an angle.

It is therefore the general object of the invention to improve the state of the art in the field of closure-free running shoes and preferably to overcome one or more of the disadvantages of the prior art.

In some embodiments, a lace-up running shoe is provided that provides comparable or better support than a lace-up running shoe.

In further embodiments, a closure-free running shoe is provided which has a particularly low weight.

In some embodiments, a closure-free running shoe is provided which stabilizes the wearer's foot while running and is very comfortable to wear.

The general task is solved by the independent patent claim. Further advantageous embodiments result from the dependent patent claims.

One aspect of the invention relates to a running shoe with a lateral side and a medial side. The running shoe has a heel area (FB), a forefoot area (VB), and a metatarsal area (MB). The front end of the forefoot area forms a shoe toe and the rear end of the heel area forms a heel edge. The running shoe includes a shoe sole and an upper part, the upper part having a textile base material. In addition, the running shoe has a group of tension bands with at least one compressive tension band and a group of tension bands with at least one compressive tension band. The group of tension straps and the group of drawstrings are part of the upper part and can optionally extend into the sole of the shoe or be attached to it. The group of tension straps is arranged in the heel area and in the metatarsal area of the running shoe and the group of tension straps is arranged in the forefoot area. The at least one tension band is designed in such a way that it exerts an inwardly directed compression force when worn. In addition, the at least one tension band is arranged in such a way that, when worn, it runs along a non-expanding line (LONE - line of non-extension) of the wearer's foot. This means that the tension band typically runs exclusively on the LONE or is arranged above the LONE of the wearer's foot. Thus, when worn, a compression force acts on the wearer's foot along a LONE. Preferably, the pressure that additionally acts on the wearer's foot through the at least one tension band can be between 0 and 100 mmHg (0 to 0.15 atm), preferably between >0 and 100 mmHg (>0 to 0.15 atm). The at least one drawstring can cause a pulling force on the upper part of the running shoe.

Preferably, the group of tension straps is only arranged in the heel area and in the metatarsal area, but not in the forefoot area, and the group of tension straps is only arranged in the forefoot area, but not in the heel area. Preferably, at least one tension band can be arranged in the heel area in such a way that it runs along a LONE of the wearer's foot when worn. Typically, the at least one drawstring extends from the lateral side of the shoe sole over the running shoe towards the medial side of the shoe sole.

Optionally, a drawstring can also extend from the medial side of the shoe sole to a second drawstring, merge into this and thus, in combination with the second drawstring, extend from the shoe sole on the medial side over the running shoe to the shoe sole on the lateral side. Preferably, the at least one tension band is arranged exclusively above the LONE of the wearer's foot, and/or arranged exclusively above an area of LONES. An area of LONES refers to an area formed by a group of LONES running in the same direction over the wearer's foot. The area can be limited or defined in particular by the outer two LONES of the group.

In some embodiments, the group of straps surrounds the entry opening substantially from all sides.

The upper part of the running shoe typically completely encloses the wearer's foot when worn. This means that the foot is not directly exposed or accessible to the environment.

A running shoe in the sense of the present invention can preferably refer to a closed shoe. In particular, it can be a sports shoe for athletics, tennis, hiking, trekking or similar, or a leisure shoe. The person skilled in the art understands that the medial side of the running shoe when worn refers to the outer inside of the shoe. In a pair of running shoes, the two medial sides point towards each other. The lateral side of the running shoe refers to the outside of the shoe when worn and is therefore on the side of the outer instep. Typically, the forefoot area is in the area of the toes and the ball of the foot, and the heel area is in the area of the heel. The metatarsal area lies between the heel area and the forefoot area. The length of the forefoot area in the longitudinal direction can, for example, be 40-55%, the heel area approximately 25-35% and the metatarsal area approximately 10-35% of the total length of the shoe sole. The heel edge is located opposite the toe of the shoe and thus refers to the vertical rear edge of the running shoe.

In some embodiments, the running shoe is a breechless running shoe. A closure-free running shoe within the meaning of the invention refers to a running shoe that does not have any laces, zippers, Velcro fasteners, buttons, snap fasteners or similar fasteners and fasteners.

The group of tension bands or drawstrings can each have only a single tension band or drawstring or several tension or drawstrings. The person skilled in the art understands that the term “the at least one tension band” can refer to both the singular and the plural.

Typically, the at least one drawstring and/or the at least one tension band is compressed when unworn. When worn, a strong tensile force or compression force can be exerted.

A tension band is typically arranged in the upper part of the running shoe in such a way that it lies on one “LONE” of the wearer's foot when worn. A LONE is a hypothetical line extending across the wearer's foot that is neither stretched nor compressed during the running movement (see Jenkins, Dressing for Altitude: US Aviation Pressure Suits, Wiley Post to Space Shuttle, US National Aeronautics and Space Administration, ISBN 9780160901 102 and Iberall, J. Basic Engineering, 1970, 251-264). If the line describes a closed geometric figure, for example a circle or an ellipse, this does not change in circumference during the running movement. The compressive tension band exerts compression on the wearer's foot when at rest. If a tension band is arranged in the upper part in such a way that it lies on a LONE when worn, this has the advantage that the tension band is essentially not stretched or tensioned during the running movement. A compression that is big enough is to hold the running shoe on the wearer's foot when at rest without exerting an unpleasant feeling of pressure, thus creating no feeling of pressure even during the running movement. This means that a relatively strong compression can be used, which on the one hand ensures a good hold of the foot in the running shoe, but on the other hand does not lead to an unpleasant feeling of pressure even during the running movement. Due to the at least one tension band, a closure can be dispensed with. This has the advantage that less force has to be used when running, since a closure, for example a common lacing, causes a restriction of movement which the runner has to overcome.

The at least one tension band and/or the at least one tension band typically has two points of attack on the running shoe, in particular on the shoe sole or on the upper part of the running shoe. The points of attack define the start and end points of the tension or tension band that runs at least over the upper part. In embodiments with several tension bands and/or with several tension bands, several tension and/or tension bands can cross over, contact or merge into one another within the respective group of tension bands or group of tension bands.

It has been shown that the group of tension bands is preferably arranged in the heel area and metatarsal area. In addition, tension straps in the forefoot area can be dispensed with, as their stabilizing effect is particularly needed in the heel and metatarsal areas.

In further embodiments, the at least one tension band is arranged in such a way that it can exert a tensile force in the forefoot area against the pronation of the foot. This reduces the angular velocity of pronation during the running movement and increases the damping effect when stepping. In addition, by reducing the speed of pronation, a stabilizing and supporting function of the foot is created when running. The at least one compressive tension band can be arranged in such a way that a tensile force is exerted from the medial side towards the lateral side of the running shoe, preferably from the medial side of the shoe sole to the lateral side of the shoe sole of the running shoe.

Preferably, the at least one drawstring is connected directly to the shoe sole on both the medial side and the lateral side. Typically, the tension straps are arranged in such a way that they each or in conjunction with one another run from the medial side over the instep of the wearer's foot to the lateral side.

In some embodiments, the group of drawstrings includes a first drawstring which extends from the shoe sole on the medial side to the shoe sole on the lateral side and which exerts a tensile force between the medial side and the lateral side of the shoe sole. The first drawstring thus extends over the instep of the foot when worn. The drawstring can be connected directly to the shoe sole or can be arranged above the shoe sole. The tension band causes the angular velocity of the foot's pronation to be reduced during the step, thereby increasing the cushioning effect.

Typically, the first tension band can run obliquely in the direction of the heel area, starting from the medial side towards the lateral side. This further improves the damping effect.

In some embodiments, the first drawstring can be arranged such that it is arranged in front of the halux of the wearer in the running direction when worn. Preferably, the first tension band runs tangentially to the Halux.

In further embodiments, the first drawstring divides the forefoot area of the upper into a first and a second functional zone. The first functional zone extends from the toe of the shoe to the first drawstring and is in the longitudinal direction biased. This allows the material to be compressed in the longitudinal direction, ie along the tarsal bones (metatarsals) of the wearer, thereby reducing the force required by the wearer when running. In the latitudinal direction, the first functional zone can be force-neutral. The term “force neutral” means that the first functional zone is essentially neither pre-stressed nor pre-stretched in the latitudinal direction at rest. The first functional zone ensures in particular that the foot is held above the sole of the shoe and cannot partially slip beyond its periphery.

It is known to those skilled in the art how a pre-tension, i.e. a contraction, or a pre-stretch, i.e. an expansion of a functional zone can be achieved. For example, this can be achieved during the production of the upper material by sewing under tension, by certain laying of a knitted fabric, by close-meshed weaving or knitting, or by additive manufacturing of the upper part of the running shoe.

In some embodiments, the second functional zone is pre-stressed in the latitudinal direction and/or pre-stretched in the longitudinal direction. The second functional zone can also be delimited, for example, by a tension band, in particular the first tension band, or another tension band. The longitudinal pre-stretch enables the anterior-posterior movement of the foot and the latitudinal pre-tension fixes the foot on the instep and thus replaces essential functions of lacing without significantly restricting the flexibility of the foot's natural movement.

In further embodiments, the group of drawstrings has a second drawstring, which extends from the shoe sole on the medial side towards the first drawstring and exerts a tensile force in the direction of the first drawstring. The second drawstring is typically connected directly to the first drawstring. Preferably, the second tension band extends from the medial side obliquely to the tip of the sole in the direction of the first tension band.

In some embodiments, the second drawstring can be arranged such that it is arranged behind the halux of the wearer in the running direction when worn. Preferably, the second tension band runs tangentially to the Halux. In particular, the Halux can be surrounded by the first and second drawstring when worn.

In further embodiments, the first and second tension bands define a third functional zone. Optionally, the third functional zone can have a substantially triangular shape, which is formed by the first and second drawstrings and the shoe sole. The third functional zone can be designed to be elastic, which means that a comfortable fit can be provided for different hallux shapes and sizes.

In some embodiments, the group of tension bands comprises a first tension band, which extends from the medial side of the shoe sole to the lateral side of the shoe sole and is arranged in the midfoot region of the running shoe. The first tension band can extend over the instep of the wearer's foot when worn. Typically, the first tension band runs in the running direction in front of the entry opening of the running shoe. Preferably, the first tension band is arranged such that it lies on one LONE of the wearer's foot when worn. The first tension band fixes the wearer's foot and prevents unwanted vertical movement of the foot relative to the running shoe.

The first tension band preferably has a medial point of attack in the metatarsal area. This can, for example, be arranged in the running direction starting from the heel edge at approximately 20 to 40%, preferably 30 to 35%, of the total length of the running shoe. Furthermore, the first tension band can have a lateral point of attack in the metatarsal area. This can, for example, be arranged in the running direction starting from the heel edge at approximately 20 to 40%, preferably 30 to 35%, of the total length of the running shoe.

In further embodiments, the first tension band and the shoe sole define a fourth functional zone in the metatarsal area and the heel area, which is force-neutral in all directions. This ensures that the function of the tension band or straps is not impaired by pre-tensioning or pre-stretching of the fourth functional zone.

The fourth functional zone can include the entire metatarsal area and heel area. In particular, the fourth zone can be divided into subzones by further tension bands, which can typically all be designed to be force-neutral or can also be designed to be partially pre-stressed and/or pre-stretched.

In some embodiments, the group of tension bands comprises a second tension band, which runs on the medial side in the heel area and extends vertically upwards from the running shoe sole at the heel edge to the first tension band. In particular, the second tension band can be directly connected to the first tension band. For example, the second tension band can only be arranged on the medial side of the running shoe and not on the lateral side. The second tension band can rise continuously in the vertical direction or can only rise vertically over a section and be partially arranged horizontally in the running direction. The second tension band provides additional stabilization in the heel area. Preferably, the second tension band is arranged such that it lies on one LONE of the wearer's foot when worn.

In further embodiments, the group of tension bands comprises a third tension band which runs on the lateral side in the heel area and extends vertically upwards from the running shoe sole at the heel edge to the first tension band. In particular, the third tension band can be directly connected to the first tension band. The third tension band is preferably arranged only on the lateral side of the running shoe and not on the medial side. The third tension band can rise continuously in the vertical direction or only rise vertically over a section and partially horizontally in the running direction be arranged. The third tension band provides additional stabilization in the heel area. Preferably, the third tension band is arranged such that it lies on one LONE of the wearer's foot when worn.

The second and third tension straps have the advantage that medial or lateral bending of the wearer's foot while running is prevented even better. This achieves an additional increase in the stability of the foot in the running shoe.

In some embodiments, the group of tension bands comprises a fourth tension band, which extends in the heel area from the medial side of the shoe sole over the heel edge to the lateral side of the shoe sole and has a slope in the vertical direction. The fourth tension band preferably extends on the heel edge to the entry opening of the running shoe. The fourth tension band is preferably arranged in such a way that it lies on one LONE of the wearer's foot when worn. The fourth tension band efficiently prevents the wearer's foot from slipping over the periphery of the shoe sole during the running movement, for example during the heel step. The combination of the first and fourth tension straps has proven to be particularly preferred, since these essentially completely enclose the wearer's foot and can fix it firmly by the compression force exerted.

The fourth tension band preferably has a medial point of attack in the heel area. This can, for example, be arranged in the running direction starting from the heel edge at approximately 20 to 30%, preferably 25 to 27%, of the total length of the running shoe. Furthermore, the fourth tension band can have a lateral point of attack in the heel area. This can, for example, be arranged in the running direction starting from the heel edge at approximately 20 to 30%, preferably 25 to 27%, of the total length of the running shoe.

In some embodiments, the first, second, third and fourth tension bands define a fifth functional zone that is biased in longitudinal and latitudinal directions.

The fifth functional zone is therefore located in the area of the entry opening of the running shoe and compresses the upper part of the running shoe when worn in the area of the ankles, thereby enabling a better hold of the running shoe on the wearer's foot. The fifth functional zone can be designed, for example, as a subzone of the fourth functional zone.

In further embodiments, the at least one tension band or the tension bands and/or the at least one tension band or the tension bands have a width of 0.5 to 4 cm. The expert understands that the width of the tension and tension band depends on the shoe size. The tension bands and/or the drawstrings can be applied to the textile base material, surrounded peripherally by it and/or be part of the textile base material. In particular, it is possible for the width of a specific tension band to vary.

In some embodiments, the upper part has an auxethic transition area between the tension band, or tension bands, and the textile base material and/or between the tension band, or tension bands, and the textile base material. The transition region can, for example, have a width of up to 2 cm, preferably between 0.5 and 2 cm.

In further embodiments, the first, second, third and/or fourth functional zone is designed auxethically. Preferably, at least the first functional zone is designed auxethically, which prevents the textile base material from crumpling during the running movement and the resulting pressure points on the wearer's foot. This can increase the durability and resistance of the upper part of the running shoe.

In further embodiments, the at least one tension band and/or the at least one tension band is connected to the shoe sole. For example, it is possible for the at least one tension and/or drawstring to be cohesively bonded to the shoe sole is connected, is sewn to it, rests on it or is at least partially surrounded by the shoe sole. Alternatively, the at least one tension band and/or tension band can run above the shoe sole along a surface of the shoe sole. When worn, in such embodiments the at least one tension and/or drawstring runs below the wearer's foot.

Ways of carrying out the invention

In the Figure 1 a running shoe 1 according to the invention is shown with a heel area FB, a forefoot area VB and a metatarsal area MB. The expert understands that the arrows indicate the area boundaries as examples and do not define sharp area boundaries. According to the coordinate system, the longitudinal direction denotes the running direction of the shoe, ie the y-direction. The vertical direction is described by the z-direction. The latitudinal direction is described by the x or -x direction. The running shoe 1 also has a toe 4 and a heel edge 5. Furthermore, the running shoe includes a shoe sole 3 and an upper part 2, the upper part 2 comprising a textile base material. In addition, the running shoe has a group of drawstrings with a first drawstring 15 and a second drawstring 16. The drawstrings 15 and 16 are stretchable in the longitudinal direction and exert a tensile force on the upper part and the textile base material. When worn, the tension straps 15 and 16 are stretched and, by developing a tensile force against the pronation of the foot, lead to the pronation angular velocity being reduced when running, thereby increasing the damping effect. This effect is further enhanced by the fact that the drawstrings 15 and 16 are each connected directly to the shoe sole. In addition, the drawstrings prevent the wearer's foot from partially slipping beyond the periphery of the shoe sole 3. Like in the Figure 1 As can be seen, the second tension band 16 runs vertically from the shoe sole on the medial side, ie, rising in the z direction, towards the first tension band 15. This forms a substantially triangular third functional zone 23. The third functional zone is pre-stretched both in the longitudinal direction, ie in the y-direction, and in the latitudinal direction, ie more perpendicular to the longitudinal direction and starting from the medial side to the lateral side over the wearer's foot in the x-direction. This enables a comfortable fit for different hallux shapes and sizes without feeling unpleasant pressure on the hallux when running.

The first tension band 15 divides the forefoot area VB into a first functional zone 21 and a second functional zone 22. Like in the Figure 1 shown, the first functional zone 21 extends from the toe of the shoe 4 to the first drawstring 15. The second functional zone 22 is delimited on the one hand by the first and second drawstrings 15 and 16 and on the other hand through the first tension band 11. The first tension band 11 extends from the medial side of the shoe sole 3 to the lateral side of the shoe sole 3 and is arranged in the metatarsal area. Like in the Figure 1 shown, the first tension band 11 generally runs in front of the entry opening of the running shoe 1, viewed from the toe 4. When worn, the first tension band 11 runs over one LONE of the wearer's foot and causes an inward direction, ie directed in the direction of the foot , compression force, whereby the foot is stabilized and held laterally, ie in the x and -x directions, and is stabilized and held in the vertical, ie in the z direction. The first tension band 11 also defines a fourth functional zone 24 of the upper part 2, which, viewed from the toe 4 of the shoe, is arranged behind the first tension band 11 and extends from there to the heel edge 5.

Furthermore, the in the Figure 1 Running shoe 1 shown has the second tension band 12, which runs on the medial side in the heel area FB and extends vertically rising from the running shoe sole 3 at the heel edge 5 to the first tension band 11. In general, several tension and/or tension bands can cross over, contact or merge into one another. The second tension band 12 surrounds the wearer's foot from the heel edge over the medial side. This stabilizes the foot in the x direction. In addition, the compression force acting on the foot from the tension band 12 ensures that the running shoe holds well on the foot. The group of tension bands in the Figure 1 Running shoe 1 shown also includes a fourth tension band 4, which above all ensures a good hold of the rear heel part in the area of the Achilles tendon. The fourth tension band 14 extends starting from the medial side of the shoe sole 3 over the heel edge 5 to the lateral side of the shoe sole 3. In addition, the fourth tension band 14 rises vertically in the direction of the heel edge, ie in the z direction, and reaches the heel edge 5 its maximum height in the z direction. The first, second, third (in the Figure 1 not shown, see Figure 2 ) and fourth tension band (11-14) define a fifth functional zone 25, which is prestressed in the longitudinal and latitudinal directions. The fifth functional zone 25 is located thus in the area of the entry opening of the running shoe and compresses the upper part of the running shoe when worn in the area of the ankles.

The Figure 2 shows the embodiment of the running shoe 1 as a top view of the lateral side. It can be seen that the tension band 15 runs obliquely from the point of application on the medial side to the lateral side in the direction of the heel area FB. The point of attack on the lateral side is therefore shifted further towards the heel edge 5 than the point of attack on the medial side. The running shoe 1 has, in addition to the first, second and fourth tension band, a third tension band 13, which runs on the lateral side in the heel area FB and extends vertically rising from the running shoe sole at the heel edge 5 to the first tension band 11. Equivalent to the second tension band 12, the tension band 13 rises continuously in the vertical direction and finally runs horizontally, ie in the y direction. The compressing straps 11 to 14 thus exert an inwardly directed force on the wearer's foot from essentially all sides, as a result of which the running shoe is held firmly on the foot.

In the Figure 3 a further embodiment of the running shoe 1 is shown. In contrast to the running shoe from the Figures 1 and 2 This only has the first tension band 15 and the first and fourth tension bands 14.

In the Figure 4 a view of the lateral side of a running shoe according to a further embodiment of the invention is shown. In contrast to that in Figure 3 In the embodiment shown, both the first and second tension bands 15 and 16 run from the medial side over the lateral side and describe a V-shape. The second drawstring 16 extends in the direction of the first drawstring 15, but only comes into contact with it in the area of the shoe sole 3 on the lateral side.

The Figure 5 shows a two-dimensional top view of an upper for an upper part 2 of a closure-free running shoe according to the invention with a group of tension straps Tension bands 11, 12, 13, as well as 14a and 14b and a group of tension bands comprising tension bands 15 and 16. The first tension band 15 runs obliquely from the front part of the halux area on the medial side in the direction of the heel edge, ie in the negative y direction, whereby the first tension band is angled at the connection position with the second tension band 16. The second tension band 16 runs from the rear part of the halux area on the medial side obliquely in the direction of the tip of the sole towards the first tension band 15 and merges into it at the connection position. The first tension band 15 divides the upper part 2 in the forefoot area into a first functional zone 21 and a second functional zone 22, which is generally also delimited by the first tension band 13. The first functional zone is, as indicated by the arrows, prestressed in the longitudinal direction and neutral in force in the latitudinal direction. The second functional zone is pre-stretched in the longitudinal direction and pre-stressed in the latitudinal direction. A third functional zone 23 is delimited by the first drawstring 15 and the second drawstring 16. When worn, this covers the wearer's halux. The third functional zone is designed to be elastic and preferably designed to be force-neutral. The first compressive tension band 11 extends in the metatarsal area of the upper part 2 from the medial to the lateral side and, viewed in the y direction, runs in front of the entry opening. When worn, the first tension band 11 runs on one LONE of the wearer's foot. The second tension band 12 and the third tension band 13 curve from the medial or lateral side towards the first tension band 11 and merge into it at a connecting position. Thus, when worn, the tension straps 12 and 13 surround at least the ankles of the wearer's ankle. A fourth tension band is formed by the tension bands 14a and 14b. These run from the heel edge towards the medial or lateral side of the upper part 2 and therefore, when worn, surround the wearer's foot at least in the area of the Achilles tendon. The wearer's foot is thus essentially completely surrounded on all sides by the tension straps 11, 12, 13, 14a and 14b. A fourth functional zone 24 is formed by the subzones 24a-d and is delimited by the first tension band 11.

In the Figure 6 a pair of feet of a wearer is shown with the corresponding LONES. The comparison with Figure 4 shows that the fourth tension band runs over the LONES in the heel area and the first tension band 11 runs over the LONES in the metatarsal area over the foot. The group of LONES in the heel area, over which the fourth strap in the Figure 4 runs, runs like in the Figure 6 shown, in the same direction over the foot of the wearer, or are arranged in sections at least partially parallel to one another. This group of LONES defines an area of LONES. The fourth tension band is arranged exclusively above this area or runs exclusively over this area.
