[0002] Sports shoe, especially snowboard shoe

[0003] Description

[0004] The invention relates to a sports shoe, in particular a ski or snowboard boot, with a shell connected to a running sole, comprising a forefoot shell for receiving the forefoot of a user and an adjoining shoe cuff for stabilizing the lower leg section of a user.

[0005] DE 10 2021 118 186 Al describes a snowboard boot comprising a sole and an upper, wherein at least one circumferential section of the upper adjacent to the sole is formed by a frame that is at least essentially dimensionally stable.

[0006] In particular, the transmission of forces while maintaining maximum flexibility during use of the shoe is considered to be in need of improvement.

[0007] The particular object of the invention is to propose a sports shoe, especially a ski or snowboard shoe, wherein a precise and effective power transmission during the exercise of the sport is to be achieved with comparatively simple means, and preferably with comparatively simple means while maintaining a high degree of flexibility.

[0008] This problem is solved in particular by the features of claim 1.

[0009] In particular, the problem is solved by a sports shoe, preferably a ski or snowboard boot, with an (outer) shell connected to a running sole, comprising a forefoot shell for receiving the forefoot of a user and an adjoining shoe cuff for stabilizing the lower leg section of a user with at least one in the upper section MEISSNER BOLTE M / DEE-057-PC 2

[0010] The shoe cuff includes a tensioning device (with at least one adjustment device) for narrowing and / or limiting the width of an entry opening of the sports shoe as required, wherein the shell is preferably formed in one piece and / or preferably has a deformation zone which is assigned to an instep area (or flexion area) between the foot and lower leg of the user in order to allow angulation between the forefoot shell and the shoe cuff.

[0011] According to a first aspect of the invention, the shoe cuff preferably comprises a support shell enclosing the heel and supporting the lower leg section of the user towards the rear, which is connected to the outsole via a fork-shaped force transmission element (preferably separate from the support shell, but indirectly or directly connected to it).

[0012] One idea based on the first aspect is to connect the shoe cuff (or a part of it, namely the rear support shell) to the outsole via a fork-shaped power transmission element. This allows for effective power transmission in a simple way (with minimal material and manufacturing effort).

[0013] The ski or snowboard boot is preferably a soft boot.

[0014] When a single-piece construction is mentioned above and below, it can be monolithic or realized through a combination of several parts. For example, there can be several interconnected (intrinsically monolithic) parts, or the respective element (e.g., the shell) can be entirely monolithic. Specifically regarding the shell, this design comprises several (intrinsically monolithic) parts.

[0015] The forefoot shell and shoe cuff can be formed from separate parts or from a single (possibly monolithic) part or several single (each monolithic) parts. MEISSNER BOLTE M / DEE-057-PC 3

[0016] The tongue of a shoe can be (partially) assigned to both the shoe cuff and the forefoot shell.

[0017] A deformation zone is understood to be, in particular, a zone that deforms more pronouncedly compared to adjacent areas (the shoe cuff or the forefoot shell), especially when subjected to stress, for example by the lower shin of the user of the sports shoe.

[0018] The forefoot shell and / or shoe cuff can be made (at least partially, possibly completely) of a (dense or non-porous) plastic, particularly by injection molding. The deformation zone and / or one or more other sections of the shell can be formed from at least or exactly one flexible material, for example, an elastomer and / or a fabric.

[0019] The tensioning device preferably comprises at least one lacing element and preferably also includes a clamping device for clamping the lacing element. Furthermore, the tensioning device may include an adjusting element (for example, a rotatable adjusting element) for increasing and / or decreasing tension. The tensioning device may be formed by or comprise a shoelace.

[0020] The deformation zone can have a triangular geometry (at least partially), with preferably one apex of the triangle pointing towards the rear end of the sole, at least substantially. Specifically, a corresponding deformation zone can be present on both sides of the tongue.

[0021] The (respective) deformation zone can have an overall (at least approximately) 5-sided shape.

[0022] The shell is preferably an outer shell in which, for example, a (functional) inner boot can be received. Such an inner boot may have a separate tensioning device (in particular comprising lacing).

[0023] The support shell and / or the fork-shaped power transmission element are preferably made of a rigid material. MEISSNER BOLTE M / DEE-057-PC 4

[0024] When a rigid material is mentioned above or below, this means in particular that the respective material is made of a dense and / or non-porous plastic, especially by injection molding. The density of such a rigid material is preferably at least 0.2 g / cm³. 3 , preferably at least 0.5 g / cm³ 3 , possibly at least 0.9 g / cm² 3 , and / or at most 10 g / cm² 3 The elastic modulus of the rigid material (at 20 °C) is preferably at least 500 N / mm². 2 , possibly at least 1000 N / mm 2 , possibly at least 1500 N / mm 2 and / or at most 5000 N / mm 2 , possibly at most 3000 N / mm 2 .

[0025] If any parameter mentioned in this disclosure is direction-dependent, the respective disclosed condition shall preferably apply to at least one direction, possibly at least two mutually perpendicular directions, possibly three mutually perpendicular directions.

[0026] If several materials are used for a particular element, the preferred conditions specified here should apply to at least one material, preferably to several or all of the materials.

[0027] When the present disclosure refers to a flexible material, it preferably refers to a material comprising an elastomer and / or a porous material and / or a fabric, for example, a cloth.

[0028] The elastic modulus of the soft material (at 20 °C) is preferably below 1000 kPa, more preferably below 500 kPa, even more preferably below 200 kPa and / or is at least 10 kPa, optionally at least 50 kPa.

[0029] In particular, a stiff material should always have a larger modulus of elasticity and / or a higher density than any soft material of the shoe (any and / or in comparison).

[0030] The density of the soft material can be at most 0.3 g / cm³. 3 , preferably at most 0.1 g / cm³ 3 and / or at least 0.01 g / cm³ 3 , possibly at least 0.1 g / cm³ 3 MEISSNER BOLTE M / DEE-057-PC 5

[0031] If parameters depend on external conditions, the external conditions should be 20 °C and 50% relative humidity and 1 bar ambient pressure.

[0032] A fork-shaped element (transmission element) is in particular understood to be an element that has at least or exactly two prongs (which are preferably directed forwards).

[0033] In specific embodiments, the force transmission element is formed by a rigid element. The force transmission element can comprise two sections, in particular a (rear) section having an (essentially O-shaped) opening, preferably at least 3 cm in diameter. 2 and / or at most 20 cm 2 The shoe has a surface area and a (front) section that is U-shaped and / or has a cutout that opens to the front. The rear section and / or the front section can each extend over a minimum of 5 cm and / or a maximum of 12 cm and / or over a minimum of 10% and / or a maximum of 50% of the shoe length.

[0034] The front and rear sections of the fork-shaped power transmission element (or a web located in the area between these sections, running at least essentially transversely to the width direction) enable a particularly effective power transmission with comparatively little material expenditure.

[0035] The fork-shaped power transmission element preferably extends over at least 50% of a shoe length and / or at most 80% of a shoe length. In particular, the fork-shaped transmission element ends at a distance in front of the ball line of the sole.

[0036] The support shell can have a lower section that encloses the lower part of the heel (U-shaped) and an upper section. The lower and upper sections of the support shell can be connected to each other by a constriction (viewed from behind), allowing the upper and lower sections to be relatively flexible relative to each other. The support shell is preferably made of a rigid material.

[0037] According to a second aspect (which is preferably combined with the first aspect), the shoe includes a comparatively stiff midsole, which is MEISSNER BOLTE M / DEE-057-PC 6

[0038] from the heel forward (especially to the ball of the foot area), so that the part of the outsole in front of the ball of the foot is comparatively flexible.

[0039] A second aspect of the invention involves providing a relatively stiff midsole that does not extend all the way to the front, so that the front part of the sole is comparatively flexible. The midsole is preferably arranged (vertically) between the fork-shaped power transmission element (according to the first aspect) and the outsole.

[0040] The ball of the foot area is determined by the shoe's configuration and begins where the toes begin. Specifically, it can start below the base of the toes. The ball of the foot area can end where the toes begin. In particular, it can encompass the area below the base of the toes (the metatarsophalangeal joints) and can end at the junction with the actual toe bones.

[0041] In numerical terms, the ball of the foot area can begin at approximately 60-70% of the total sole length (measured from the heel) and / or end at 75-80% of the total sole length. The total sole length should be measured from the rearmost to the foremost point.

[0042] Specifically, the indication of an extension to the ball of the foot can refer to an extension that reaches to or into the ball of the foot (but not beyond, viewed from the heel).

[0043] In combination or alternatively to extending to the ball of the foot, the comparatively stiff midsole can extend from the heel to at least 55%, preferably at least 60%, possibly at least 65% or at least 70% and / or at most 80%, preferably at most 75% of the total length of the sole.

[0044] This can be understood as a clarification or as an alternative to the second aspect. MEISSNER BOLTE M / DEE-057-PC 7

[0045] The sole is preferably made of a relatively stiff material, in particular a material with relatively high flexural and / or torsional stiffness. The flexural modulus of the material can be at least 10 MPa, preferably at least 50 MPa, and more preferably at least 100 MPa and / or at most 400 MPa (at 20 °C). The torsional modulus can be at least 5 MPa, preferably at least 20 MPa and / or at most 100 MPa.

[0046] The material of the midsole can consist of foam and / or be porous.

[0047] The material may include: EVA and / or PU and / or another type of foam.

[0048] The cable-shaped force element preferably comprises a thermoplastic, in particular TPU.

[0049] The (rigid) support shell preferably comprises a thermoplastic, in particular TPU, and / or a polyamide, for example PA6 and / or PA66. The shoe tongue may comprise a polyamide, in particular PA6 and / or PA66, and / or TPU. The forefoot shell and / or the shoe cuff may be made of a fabric (mesh) and / or PU. A side patch may have a mesh with TPU welding. Specifically, the mesh may be pressed, punched, and welded to a TPU layer. Alternatively or additionally, leather and / or textiles and / or similar materials may be used.

[0050] The midsole can have cushioning properties, in particular being relatively easy to compress.

[0051] The compression modulus of the midsole can be at least 0.1 MPa, preferably at least 1 MPa, more preferably at least 5 MPa or at most 10 MPa and / or at most 100 MPa, preferably at most 50 MPa.

[0052] One advantage of the midsole (which doesn't extend all the way to the front) is its comparatively high stability, especially when snowboarding. At the same time, the toe area remains free of the midsole, allowing for particularly precise control of the rider's movements. In this area, direct contact with the snowboard is especially beneficial. MEISSNER BOLTE M / DEE-057-PC 8

[0053] The task is further solved according to a third aspect (which is preferably combined with the first and / or the second aspect) by the fact that a tongue of the shoe has a (nearly) rectangular C- or U-shaped cross-section, at least in the upper area which supports the lower leg section of the user forwards.

[0054] One idea based on the third aspect is to deviate from the usual, essentially circular segment-shaped section and choose a rectangular cross-section. This allows the tongue to slide effectively towards the inside of the shoe and easily achieve the best possible connection to the person's foot. This also improves power transmission and the overall stabilization of the shoe (especially when snowboarding).

[0055] A (nearly) rectangular C- and / or U-shaped cross-section is understood to mean, in particular, that the tongue is formed in cross-section (transverse to its longitudinal extent) from three flat sections (straight sections), wherein two flat sections form corresponding U-legs and a third flat section connects these U-legs to each other. The connecting areas may have a sharp edge, but are preferably rounded. The angle of each leg relative to the connecting section may be at least 90°, preferably at least 100° and / or at most 130° or at most 110°. An intermediate area between each leg and the connecting section may (if rounded) extend over at least 2 mm or at least 5 mm and / or at most 10 mm. The (respective) flat section may be at least 2 cm, preferably at least 4 cm or at least 5 cm long.

[0056] A curvature in the area of ​​the rounded corner can be at least 0.1 mm' 1 , preferably at least 0.2 mm' 1 , possibly at least 2 mm^and / or at most 1 cm -1 , possibly at most 5 mm' 1 or at most 3 mm' 1 be.

[0057] The condition(s) for the tongue cross-section proposed above should preferably apply to at least one cross-section, preferably at least to cross-sections that together comprise at least 50% of the tongue length, preferably at least 80% of the tongue length. MEISSNER BOLTE M / DEE-057-PC 9

[0058] The problem is further solved in particular according to a fourth aspect (which is preferably combined with the first and / or second and / or third aspect) by a tongue (in particular the tongue according to the third aspect), wherein the tongue of the shoe has at least one longitudinal rib extending (approximately) in the longitudinal direction of the same.

[0059] One idea based on the fourth aspect is to stabilize the tongue with a longitudinal rib. This achieves a further beneficial stabilization of the entire shoe in a simple way, thus improving its performance during sports, especially snowboarding.

[0060] A longitudinal rib extending in the longitudinal direction is understood to mean, in particular, a rib that extends along the tongue, wherein the longitudinal direction of a tongue (usually) runs from top to bottom (or vice versa) or obliquely from top to bottom (or vice versa). The longitudinal rib can be straight, but preferably it is not straight at least in some sections and / or has a bend. The longitudinal rib can be at least 5 cm, preferably at least 10 cm and / or at most 20 cm long. The longitudinal rib can extend over at least 20%, preferably at least 50% and / or at most 90% of the tongue's length.

[0061] Preferably, at least or exactly two longitudinal ribs are present.

[0062] The longitudinal rib can be shaped as a (relatively shallow) V (in a front view), with one leg of the V extending downwards and another leg extending upwards. Particularly preferably, the longitudinal rib is shaped (in a front view) such that its central (vertically) area is closer to the center line of the tongue than its two ends. Particularly preferably, two longitudinal ribs approach each other in their respective central areas and diverge from each other in their peripheral areas.

[0063] The (respective) longitudinal rib can be triangular or trapezoidal in at least one cross-section. MEISSNER BOLTE M / DEE-057-PC 10

[0064] The (respective) longitudinal rib can be formed by an arch (in a front view).

[0065] Overall, such a longitudinal rib (especially a pair of such longitudinal ribs) achieves a stable connection of the person's foot, advantageously allowing bending in the instep area of ​​the foot.

[0066] The tongue may (in front view) have recesses on both sides, especially where two longitudinal ribs approach each other.

[0067] The following are further training courses that can each be combined with the first, second, third and / or fourth aspect (unless the context indicates otherwise).

[0068] In design, the forefoot shell and the shoe cuff can have a longitudinal gap extending from the upper entry opening into the forefoot shell, which can be opened (or spread) to a greater or lesser extent for entry and / or exit from the shoe, and to which a tongue attached to the forefoot shell is assigned, which can be moved by means of the tensioning means to narrow (or limit) the width of the entry opening into the shoe (more or less far) in the direction of the rear support shell (or into the shoe) as required.

[0069] Preferably, the support shell in the area of ​​the ankle joint (in particular in the area between the part enclosing the heel and the upper part supporting the lower leg section of the user to the rear) has at least one (in particular several) lateral recess(s) which preferably limit at least the rear section of a deformation zone to the rear, bottom and top.

[0070] The tongue is preferably shaped with a waist, particularly in the area of ​​the deformation zone of the shell.

[0071] A tapered section of the tongue preferably limits a front (inside the shoe) part of the deformation zone forwards, downwards, and upwards. MEISSNER BOLTE M / DEE-057-PC 11

[0072] In specific embodiments, a tongue has in particular two longitudinal ribs extending (approximately) parallel to each other.

[0073] As designed, the two longitudinal ribs approach each other to a minimal distance from each other when viewed from above on the tongue at the level of the deformation zone of the shell (or in the waisted area of ​​the tongue).

[0074] At least one longitudinal rib can extend on the outside and be formed by material deformation and / or material accumulation.

[0075] A front part of the outer shell may be closed by a comparatively stiff toe cap.

[0076] A tongue can be attached to a toe cap, in particular adhesively connected to it.

[0077] According to a fifth aspect (which is preferably combined with the first and / or second and / or third and / or fourth aspect), the (outer) shell can comprise (comparatively) rigid shell elements on both sides of the forefoot shell and shoe cuff, which can each be connected to each other in the area of ​​the deformation zone by an acute-angled connecting bridge.

[0078] The areas of the outer shell between the rear support shell and the shell elements on the one hand, and the shell elements and the fork-shaped force transmission element (or its two prongs extending outwards) and possibly at least the front section of the (comparatively) stiff intermediate sole on the other hand, can be filled by at least one textile surface element.

[0079] The area between the two legs of the acute-angled connecting bridges can each be filled by a textile surface element.

[0080] Areas bounded by a waist of the tongue can be filled by textile surface elements.

[0081] Further embodiments are described in the dependent claims. MEISSNER BOLTE M / DEE-057-PC 12

[0082] The invention will now be described with regard to further features and advantages using an exemplary embodiment, which is explained in more detail with reference to the figures. These show:

[0083] Fig. 1 shows a snowboard boot in side view;

[0084] Fig. 2 shows the snowboard boot according to Fig. 1 in an exploded oblique view;

[0085] Fig. 3 shows the tongue of the shoe according to Figs. 1 and 2 in a front view; and

[0086] Fig. 4 shows a cross-section through the tongue in an upper section thereof.

[0087] In the following description, the same reference numbers are used for identical and equivalent parts.

[0088] Figures 1 and 2 show a sports shoe 1 (snowboard boot) with a shell 2 connected to a running sole 12, comprising a forefoot shell 3 for receiving the forefoot of a user and an adjoining shoe cuff 4 for stabilizing the lower leg section of the user. The shoe cuff 4 has at least one tensioning device 6 effective in the upper section of the shoe cuff for narrowing and / or limiting the width of an entry opening 8 of the sports shoe 1 as needed. An inner boot is indicated by the reference numeral 5.

[0089] The shell 2 preferably has a deformation zone 9, which is assigned to an instep or flexion area between the foot and lower leg of the user in order to allow angulation between the forefoot shell 3 and the shoe cuff 4.

[0090] The shoe cuff 4 has a support shell 10 (see Fig. 2) that encloses the heel and provides posterior support in the lower leg section of the user, and is connected to the outsole 12 via a fork-shaped force transmission element 11 with prongs 24. MEISSNER BOLTE M / DEE-057-PC 13

[0091] The clamping device 6 can be clamped via a rotary device 7. The clamping device 6 preferably comprises a lacing mechanism.

[0092] The forefoot shell 3 and the shoe cuff 4 have a longitudinal gap 40 extending from the upper entry opening 8 into the forefoot shell 9. This gap can be opened or spread to a greater or lesser extent for entry into or exit from the shoe. A tongue 19 attached to the forefoot shell is associated with this gap (see Fig. 2). The tongue 19 can be moved more or less towards the rear support shell 10 or into the shoe, as required, by means of the tensioning devices, to narrow or limit the width of the entry opening 8. A front part of the outer shell 2 is closed by a rigid toe cap 20. Areas of the outer shell 2 between the rear support shell 10 and the shell elements 22a, 22b on the one hand, and between the shell elements 22a, 22b and the fork-shaped power transmission element 11, or its two outwardly extending prongs 24, and, if applicable, the toe cap 20, are open.At least the front section of the rigid midsole 13, on the other hand, is filled by textile surface elements 26. An area between the two legs of the acute-angled connecting struts 23 is each filled by a textile surface element 27.

[0093] Between the fork-shaped power transmission element 11 and the outsole 12, a comparatively stiff midsole 13 is arranged, which extends from the heel to the ball of the foot area of ​​the outsole, so that a part 14 of the outsole 13, which lies in front of the ball of the foot area, is comparatively flexible.

[0094] The shell 2 has rigid shell elements 22a, 22b on both sides of the forefoot shell 3 and shoe cuff 4, which are connected to each other in the area of ​​the deformation zone 9 by an acute-angled connecting bridge 23.

[0095] The tongue 19 of the shoe has an almost rectangular C- or U-shaped cross-section in its upper section 15, which supports the lower leg section of the user forwards (see Figs. 2 and 4). The support shell 10 has lateral recesses 17, 18 in the area of ​​the ankle joint, i.e., in the area between a part 16 enclosing the heel and an upper section 15 that supports the lower leg section of the user backwards. MEISSNER BOLTE M / DEE-057-PC 14

[0096] which at least limit the rear section of the deformation zone 9 to the rear, bottom and top.

[0097] The tongue 19 also has (see especially Fig. 3) two longitudinal ribs 21 extending approximately parallel to each other.

[0098] Figure 4 shows again the cross-section through the tongue in the upper section 15. The rectangular configuration is clearly visible.

[0099] It should be noted here that all parts described above, considered individually and in any combination, especially the details shown in the drawings, are claimed as essential to the invention. Modifications to this are familiar to those skilled in the art.

[0100] Furthermore, it is noted that the broadest possible scope of protection is sought. Therefore, the disclosure contained in the claims can also be specified by features that are described by further features (even if these further features are not necessarily included). It is explicitly noted that parentheses and the term "in particular" are intended to emphasize the optionality of features in the respective context (which does not imply that a feature is mandatory in the corresponding context without such indication). The term "element" is preferably intended to denote a coherent structure that may in turn be connected to at least one other structure (to form a potentially monolithic and / or internally immovable overall structure) or may be distinct from all other structures.
