Description

"Shoe, especially running shoe"

description

The invention relates to a shoe, in particular running shoe, according to the preamble of claim 1.

Running shoes, which are adapted to the particular needs of a runner, are known in the art, with reference being made, for example, to DE 20 2005 013 798 Ul. In such running shoes, the ball of the foot is arranged centrally above a rolling or tipping line of an underside of the sole (ball roller). The rolling or tilting line determines at which time the heel of the current person lifts. Overall, the running shoes mentioned in the prior art are perceived as unsatisfactory especially in terms of ergonomics, such shoes are disadvantageous according to the prior art, in particular due to the occurrence of high pressure loads during running and especially when unwinding, for diabetics. It is therefore an object of the present invention, a shoe, in particular

Running shoe to suggest that solves the above problems and leads to improved ergonomics and improved distribution of power while running. This object is achieved by a shoe, in particular running shoe according to claim 1.

In particular, the object is achieved by a shoe, preferably a running shoe, having a predetermined bale line extending from an inner ball point to an outer ball point and having a bale roller which is offset rearwardly toward a heel end by a mean bale roll distance from the ball line. wherein the shoe further has a shaft and an insole arranged above the outsole, which is adhesively bonded to a shaft edge on an upper side of the outsole.

An important idea of the invention is that a rolling or tilting line is offset in a shoe according to the invention relative to the ball of the foot to the rear. This has the consequence that the shoe rolls off the bale while running. This in turn reduces a rolling resistance and thereby improves the ergonomics and concomitantly occurring during running pressure loads, which is particularly for people with skin and / or circulation problems, especially in the legs and / or feet, a great advantage. The bale line determines the bale position and is an imaginary line between the bale of the big and small toe (or between an inner and an outer bale). The ball line is thus determined on the basis of predetermined proportions of an individual foot or of an average foot that forms the basis of the shoe. Each shoe thus has a clearly defined ball line, which can be determined with customary measurements. For example, the bale line may divide a sole length into 37% forefoot length and 63% hind foot length.

At the same time, the shoe according to the invention has a shaft and an insole glued to the upper side of the outsole. By this measure according to the invention, the stability of the shoe, in particular running shoe, increased and thus improves the grip of a foot in the shoe, wherein by the on Top of the outsole bonded insole the stiffness, in particular torsional rigidity of the shoe is optimized

According to one embodiment of the invention, the insole is rigid, i. in normal use stiff, namely torsion and bending resistant trained. Advantageously, the torsional rigidity or torsional stability of the shoe according to the invention and in particular the torsional rigidity or torsional stability of the outsole thereof can be further improved, so that in use of the shoe according to the invention a pressure load acting on a soleplate is distributed substantially evenly over the substantially entire sole of the foot and, in particular during running, no pressure peaks occur, as is the case with conventional shoes known from the prior art, which is particularly painful for persons with skin and / or circulation problems, especially in the legs and / or feet. liable and therefore disadvantageous. An inventive shoe is thus particularly well suited for such a group of people, the shoe according to the invention is due to its optimized properties for all other people particularly comfortable and comfortable to wear and is particularly well suited for walking, walking, walking and running.

According to one embodiment of the invention, the shoe according to the invention, in particular a running shoe, has a tarsal area and a metatarsal area (meditararseal zone), the tarsal area being softer on an inner tarsal margin area than on an outer tarsal area. Edge portion and / or wherein the metatarsal region at an inner metatarsal edge portion is formed on average harder than at an outer metatarsal edge portion. Here and below, the terms "inside" and "inside" are intended to mean that the element referred to in the use of a pair of shoes is turned to the other shoe. Accordingly, "outside" or "outside" is intended to mean that the referenced element in the use of the shoe pair is the other shoe further. Under "hardness" can be understood the mechanical resistance, the material of the one edge section of a test specimen from the Opposes material of the other edge section. The hardness can be measured, for example, according to Mohs, Martens or Brinell.

According to an even more general idea, the inner tarsal area edge portion may be configured to averagely resist this lower than the outer tarsal area edge portion when the foot is put on. Likewise, the inner metatarsal edge portion may be formed such that, when placed, it presents on average greater resistance than the outer metatarsal edge portion. This can be achieved for example by a different bulge or profiling, in particular tread depth. In this way, the shoe according to the invention can be optimally adapted to the needs of a consumer or user. In any case, such an adjustment of the mechanical resistance of the outsole allows a particularly ergonomic running. In particular, the course of resistance of the sole of the natural S-shaped rolling line of the human so follows that on a foot located in the shoe, respectively, the foot sole acts a substantially uniform and coordinated distribution of forces. This is a first ground contact on slightly supinated heel instead.

While the entire foot has contact with the ground, the main load increasingly shifts to the metatarsophalangeal joint before the new step is initiated over the big toe. According to the invention thus both the profile hardness and the tread depth is ergonomically adapted to the desired requirements.

Especially in combination with the set-back bale roll, a synergistic, efficient, energy-saving and less stressful walking and running is possible. It allows a natural rolling action with stable placement on the heel and rolling over the forefoot. Furthermore, the up and down as well as the stance phase is facilitated. Overall, lower fatigue and stress symptoms of the feet are the result. As a result, the overall movement is improved and a healthy gait and running picture is achieved. According to one embodiment of the invention, the bale roll spacing may be at least 2 mm, preferably at least 3 mm, more preferably at least 5 mm, or at least 0.5%, preferably at least 1%, more preferably at least 1.5% of a sole length. Particularly suitable is a bale roll spacing of about 5 mm has been found. The bale roll spacing may be at most 10 mm, preferably at most 7 mm or at most 2.5%, preferably at most 1.7% of a sole length, measured along the longitudinal center axis.

The bale roll can, at least in certain areas, run at a predetermined, oblique angle with respect to a longitudinal center axis, in particular following the natural course of the bale. This can further improve the ergonomics while walking.

According to one embodiment of the invention, the sole has a bowing of a forefoot area and / or an increased tip blasting of, for example, at least 10 mm, preferably at least 15 mm. In interaction, in particular with the set-back bale roller, a particularly energy-saving walking can thereby be made possible.

In a concrete embodiment, a midsole, in particular of ethylene vinyl acetate (EVA) and / or polyurethane (PU) is provided. Also, a bale roll of the midsole may be disposed at a predetermined midsole ball roller spacing behind the bale line. The midsole-bale roll distance may coincide with or be defined by the bale roll spacing of the (total) sole. By such a measure, the step division is further improved and facilitates the rolling of the foot. The (cushioning) material of the midsole, especially EVA or PU, can be adjusted harder or softer depending on the application.

Preferably, the sole comprises a pronation support in a foot arch area. This pronation support can also be used, especially in harder material, such as EVA or PU and be formed in terms of their shape and hardness to stabilize the arch of the foot.

This improves the stability and sure-footedness when walking. In a specific embodiment, the sole has a forefoot cushioning element. A degree of firmness of the forefoot cushioning element may be adjusted such that the step design flows and is not interrupted. The shape and nature of the forefoot cushioning element can be adjusted so that it is adapted to the foot anatomy or the natural appearance of the foot and relieves the pressure points. The forefoot cushioning element is preferably made of a harder material than the midsole or the other components of the midsole.

Furthermore, at least one heel cushioning element may be provided in a heel region whose material, for example EVA or PU, is also preferably made harder than the material of the midsole. The heel cushioning element (heel wedge) may be designed so that it absorbs the initial impact and initiates the Abroilbewegung. This optimally protects the joints and optimizes the rolling motion. Overall, forefoot cushioning, heel cushioning and torsional stabilizer further enhance ergonomics while running.

Furthermore, the outsole in its rear region facing the heel, in particular a plate or rod-shaped, reinforcement of a torsionally and bending resistant material, preferably made of plastic or metal, have. Such an element is a torsion stabilizer, which is also preferably made of a harder material than the material of the midsole. The torsion stabilizer is provided in a metatarsal area and serves as a midfoot bridge and increases the stability of the torsional movement, so that it advantageously prevents a rotation of the forefoot to the heel during the rolling movement. Preferably, the sole comprises a heel bevel, wherein a border line of the chamfer closer to the forefoot region is offset rearwardly at its inner end, opposite the outer end. According to a further embodiment of the invention, a shoe inner is substantially seamless, wherein in particular portions in the shoe interior, which adjoin a foot, are seamless. Furthermore, the shoe according to the invention advantageously has a soft shaft edge and, as desired, in particular in the forefoot and / or toe region a soft, yielding front cap, so that according to the invention all sections and parts of the shoe attached to a foot, an ankle and / or a lower leg abutting soft, resilient and are formed without bumps or openings, so that neither in the shoe itself nor at the shaft edge in use pressure points occur that lead, especially in persons with skin and / or circulation problems to adverse irritation of the skin or tissue could. By ensuring such a soft and resilient shoe interior and soft sheep's edge of the shoe according to the invention for persons with skin and / or circulation problems, for example, for diabetics, particularly well suited.

Furthermore, according to a preferred embodiment of the invention, the shoe according to the invention has a removable insole in the form of a padded sole, which preferably has a pressure peak reduction, in particular in the ball area. The insole insertable into the shoe according to the invention has a thickness in the range of 3 mm to 15 mm, preferably in the range of 6 mm to 12 mm and particularly preferably in the range of 7 mm to 10 mm. This insole, which, as mentioned above can also be designed as a sole, is made in this case of a soft and resilient material, so that no pressure points and / or pressure peaks can emanate from this insole when using the shoe. Furthermore, it should be noted that the insole according to the invention is designed so that it can be removed and replaced by custom-made dimensional and / or model inserts. can, by which the foot of a carrier can be supported individually.

Furthermore, the shoe according to the invention may have a leg edge that is substantially raised by the height of the pad sole and / or a forefoot area and a metatarsal area bounded at the rear by the ball line, so that an inner volume of the forefoot area compared to a shoe with a conventional insole whose height is typically less than 3 mm is increased by a range of 7% to 15%, preferably 9% to 13%. In this way, the shoe according to the invention can be provided particularly advantageous with custom-made Maß- and / or model inserts, which are generally designed significantly higher than conventional shoe insoles, without the shoe inner volume is thereby uncomfortably reduced and / or the heel area is raised so far in that pressure points would occur at the rear shaft edge of a shoe. The shoe according to the invention thus has an interior space which, even with the use of special inserts adapted to one foot, has sufficient internal volume in order to reliably exclude the occurrence of pressure points both downwards and upwards and towards the sides, so that damage to one located in the shoe according to the invention foot is certainly counteracted.

Incidentally, it should be noted that the bale roll is offset rearwardly toward a heel end relative to the ball line in the shoe of the present invention, this offset arrangement being disposed substantially parallel to the bale line and extending from an inner bale point to an outer bale point. the outer edge of the outsole surrounding the forefoot defines a first wrap having a first length, a second wrapper following the peripheral edge of the outsole surrounding the forefoot and having its start and end points associated with respective opposite ends of the offset bale roll , a second length, the second length having a range of 9% to 14%, preferably a range of 9.8% to 12.5%, of greater length than the first length. The extent to which the bale roll is opposite the Baltenlinie in A shoe according to the invention is offset towards the rear end in the direction of the heel end, thus orienting itself on the peripheral edge of the outsole which surrounds the forefoot, the respective length of the respective covering being on the one hand at the respective opposite points of the ball line and, in the case of the rearwardly offset ball roller, measured at the respective opposite end points of the bale roll.

Further embodiments emerge from the subclaims. The invention will also be described in terms of further features and advantages based on embodiments, which are explained in more detail with reference to the drawings.

Hereby show:

Figure 1 is a schematic representation of a sole for a running shoe according to the invention in an exploded view including a strip for the production of the sole. and FIG. 2 shows a sole for a running shoe according to the invention in a view from below (partially in exploded view).

In the following description, the same reference numerals are used for the same and like parts.

Fig. 1 shows a schematic representation of a sole 10 for a running shoe according to the invention in an exploded view and a last 11 for the production thereof. The strip 11 comprises a set-back ingot roll 12 and is characterized by a bend 13 and a comparatively high peak blasting 14 of, for example, at least 10 mm. The ingot roll 12 defines, at least in part, the bale roll 38 of the sole 10 during manufacture, as can be seen in FIG. The bale roll of the sole 10 is after production about 5 mm behind the natural bale position. The sole 10 comprises an insole 15, a midsole 16, a torsion stabilizer 17, a heel wedge 18 as heel cushioning and an outsole 19 with a profiling. About the insole 15, the hardness and flexibility of the shoe can be at least partially adjusted, and thus the application of the shoe can be defined. In this case, a gestrobelte embodiment with a comparatively soft textile insole provide high flexibility. According to a preferred alternative according to the invention, however, the insole is glued, namely in particular with a shaft edge at the top of the outsole. A hard insole promotes stability while running and also allows a well-defined, especially uniform, distribution of forces and surface loading.

In the midsole 16 a forefoot cushioning 20 and a pronation support 21 is integrated. Both the forefoot cushioning 20 and the pronation support 21 are made of a material that is harder than the other components of the midsole 16. A midsole bale roller 22 is also set back to facilitate the rolling of the foot. The midsole bale roll is defined by a lower crest line of the midsole.

The pronation support 21 is arranged in a foot arch region 23 on an inner edge 24 of the midsole 16 and promotes a pleasant pronation control or stabilization of the arch of the foot. In the present embodiment, the pronation support 21 is disposed within a longitudinal center axis 40 and the inner edge 24 of the midsole 16. The forefoot cushioning 20 is arranged in a forefoot region 25 of the midsole 16 and has a somewhat lower shape in order to relieve the pressure points.

The sole 10 is subdivided below in two different ways: on the one hand into the forefoot region 25 and into the rear foot region 42. These two regions are separated by the ball line. On the other hand, following the anatomy, a subdivision into tarsal area 28, midfoot area 29 and Toe area 30 made. The ball line 37 is located within the

Midfoot area 29.

The midsole 16 is, if desired, arranged in the shoe below the insole 15. Below the midsole 16, the plate-shaped torsion stabilizer 17 and the heel wedge 18, or respectively the heel cushioning, are arranged. The heel wedge can absorb the onset of impact and initiate the rolling motion, so that the joints are better protected and the rolling motion is improved. The heel wedge 18 is wedge-shaped and widens in the direction of a heel end 26 of the sole 10. The torsion stabilizer 17 is provided in the arch region 23 and can reduce or prevent the rotation of the forefoot in the event of a rolling movement. Below torsion stabilizer 17 and heel wedge 18, the outsole 19 is arranged. A profiling 27 (see also FIG. 2) is adapted to the natural gait pattern of the human eye and follows the S-shaped rolling line. The first contact with the ground may take place on a slightly supinated heel. Furthermore, the profile hardness and tread depth of the sole of the shoe according to the invention can be adapted to the different requirements. In Fig. 2 is a view of the sole 10 is shown from below. The outsole 19 is in this case subdivided into a tarsal region 28, a midfoot region 29 and a toe region 30. Here, an inner metatarsal edge portion 33 is harder than an outer metatarsal edge portion 34. An inner toe margin portion 35 is also harder than an outer toe area edge portion 36.

Furthermore, a bale line 37 is shown in FIG. 2, with respect to which a ball roller 38 is offset to the rear by a ball roller spacing 41, as predetermined by the strip ball roller 12 and the midsole bale roller 22. The thus defined bale roll 38 is offset in the present example by 5 mm with respect to the ball line 37 towards the rear in the direction of the heel end 26. The sole comprises a heel slope 44, wherein a border line 43, which lies closer to the forefoot region, is set back at its inner end. The sole 10 may be constructed in the sense of a modular system. In particular, a set of several strips and / or insoles and / or midsoles and / or torsion stabilizers and / or heel wedges and / or outsoles may be provided. In this case, all elements in hardness, material design and shape can be adjusted individually and therefore the sole to different needs and functions, in particular to the needs of people with skin and / or circulation problems, especially feet, such as diabetics adapted. Thus, the area of use of the sole advantageously increases significantly. 2, the course of the first envelope 45 is shown around the peripheral edge of the outsole surrounding the forefoot. The second envelope 46, also shown schematically, is made longer than the first envelope 45. The first envelope 45 extends around the peripheral edge of the outsole, which is associated with the forefoot, from the opposite ends of the ball line 37, respectively Envelope 46 each extends from the opposite ends of the bale roll 38 about the peripheral edge of the outsole surrounding the forefoot. In the following table, the last volume, the length and the width and the position of the bale roll of the shoe according to the invention are compared to the corresponding dimensions and the ball line of a conventional shoe, wherein it is clear that the second envelope 46, that of the recessed ball rollers 38 of a shoe according to the invention is longer than the first envelope 45 associated with a conventional shoe. ί Bars Volume: Equivalent Shoe Vs. conventional shoe
