Sole with training element and shoe

FIELD OF THE INVENTION

The invention relates to a sole with at least one training element which protrudes from the sole over the flat outsole and forms at least part of the footprint of the sole, as well as a corresponding shoe.

The term sole here refers to the so-called shoe bottom. This is the part of a shoe that is in contrast to the shoe upper below the human foot. The shoe bottom may consist of several layers or layers, which are also referred to as sole. The insole refers to the part of the sole, which lies within the shoe and comes directly into contact with the sole of the foot. The outer sole or outsole is accordingly the outer part of the shoe bottom which is in contact with the ground. Between insole and outsole, one or more midsoles may be arranged, which are usually used for damping. The individual layers of the shoe bottom, referred to as soles, are generally essentially congruent and correspond to the shape of the sole of the foot.

Between the various layers of the shoe bottom, on the inside of the insole and / or on the outside of the outsole, other materials may be provided which do not extend over the entire sole surface, such as cushion pads or heels.

The shoe bottom or sole (s) are divided longitudinally into three areas: the forefoot area in which the toes and bales of the foot come to lie, the metatarsal area in which the arch of the foot is located, and the heel area in which the heel rests. Each of these areas comprises in the longitudinal direction about one third of the shoe bottom or the sole (s).

The footprint of the sole is that part of the sole, more precisely the outsole, which touches the flat surface of the ground when the sole is placed on a ground. In this case, the sole will usually be aligned horizontally, with the training element in any case touches the ground. 2

By the term "flat outsole" is meant that it has no elevations or heels, but even or, following the sole of the human foot, is slightly curved.

The term shoe here means both a closed shoe, where the shoe upper 5 surrounds the entire foot, such as shoe, boots or boots, as well as an open shoe, such as a sandal or a slipper. When the shoe is open shoe sole surrounds only part of the foot.

PRIOR ART It is known to provide for training of the muscles elements in or at various points of the sole, which cause instability of the sole and animate the wearer of the sole to movements that compensate for the instability.

For example, US 2010/0251567 A1 discloses shoes which have bulges on the sole in the region of the heel and the forefoot. These 15 lobes cause a tilting or walking instability that needs to be balanced by the user, creating a training effect. The bulges can be filled with air or another fluid.

The US 2010/0269370 A1 shows a sneaker with sole, in which a bladder is installed, which contains air at a low pressure. This causes instability which the user must balance while wearing the shoes. In this way, the coordination ability and the musculature of the user are trained. By means of a valve, the air pressure in the bladder can be adjusted to the weight of the user. The bladder corresponds approximately to the length and width of the sole.

WO 2011/068782 A1 relates to shoe soles which have downwardly projecting, 25 compressible elements made of an elastomeric material, for example in the form of a spherical segment. These elements cause a natural instability, which has a training effect for the user with regard to their balance and musculature. The elements are provided in the area of the heel and in the area of the forefoot. 3

The CN 201860887 U refers to shoes that have at the outer soles air cushions, which protrude down from the soles. The air cushions result in a training effect for the user when standing, walking and running. It is an air cushion at the big toe, one at the ball and 5 at the heel.

In WO 2011/133686 A1 outer soles are shown, which have convex-shaped sections in the region of the forefoot and the heel.

A disadvantage of the soles of the cited publications is that they destabilize the foot only in the area of the forefoot and / or the heel, or that, as in FIG. 10 of US 2010/0269370 A1, the entire sole of the foot is destabilized. The soles or shoes described above are intended for everyday use for locomotion, but can thus only have a limited training effect.

Training devices are also known which have a disc on which both feet are placed, wherein the disc is curved on the underside or a curved, approximately elastic, element is attached thereto. With the feet now the person standing on the disc must constantly by weight shifting try to reach a stable position and hold them. Although such training devices have a better training effect on the leg muscles than the aforementioned soles or shoes, but are relatively large and unwieldy and require a corresponding amount of storage space.

PRESENTATION OF THE INVENTION

It is therefore an object of the invention to provide soles or shoes which provide similar training effects as disc-shaped balance training devices, but are less bulky than these.

The object is achieved by a sole according to claim 1, with at least one training element that protrudes from the sole over the flat outsole and forms at least part of the footprint of the sole, so that the training element - or in several training elements their common 4

Envelope - his or her greatest height in the middle Längsdrittei the sole has, wherein in horizontal alignment of the sole neither the front nor the rear longitudinal third of the sole form part of the base.

The height of the training element is measured normal to the surface of the sole. That part of the training element that has the greatest height forms part of the footprint of the sole.

Since the training element according to the invention makes the sole so unstable, the sole accordingly generally has no equilibrium position and therefore not a single footprint (such as a sole of a conventional shoe), but the sole or the shoe according to the invention is once forward, once tilted back, etc., if this is placed on a flat horizontal surface, insofar the sole according to the invention is characterized in that it touches this surface in a horizontal arrangement on a horizontal flat surface only with the training element and not with the outsole of the front or back third of the sole. Only in this way can a tilting movement of the sole in the sense of balancing and a corresponding training effect be ensured.

If several training elements are provided, then their envelope takes the place of the contour of a single training element. The envelope then lays down the footprint in the horizontal position of the sole, with the sole then actually standing on one or more of the training elements.

The fact that the greatest height of the training element (or the envelope of the plurality of training elements) is in the middle longitudinal third of the sole, the front or rear longitudinal third thus thus has a lower part of the training element 25 or no part of the training element, in any case both forward as well as backwards instability of the sole, so that the wearer of the sole has to balance its weight at least in the longitudinal direction of the sole.

In this sense, it can be provided that, in the case of an inclination of the sole in the longitudinal direction of up to 5 °, preferably of up to 15 °, particularly preferably of up to 30 to 25 °, in particular of up to 45 ° - respectively of the horizontal alignment of the sole measured from - neither the front nor the rear third of the sole

E form part of the stand area. In other words, the position of the training element relative to the sole and the dimension of the training element are chosen so that when tilting the sole at the indicated angle! the sole neither at the front (in the front third) nor at the back (in the rear longitudinal third) touches the (even) ground when the training element touches the ground. Of course, angles of more than 45 ° are possible.

The instability of the sole is enhanced when the training element is located exclusively on the middle longitudinal third of the sole, because then lies between the middle longitudinal third! the sole on the one hand and the front and rear longitudinal third! On the other hand, a maximum height difference before. The term "arranged on the middle longitudinal third" expresses that the training element there, such as mechanical or magnetic, is connected to the sole, so anyway the outer sole touches. However, the training element does not touch the front or rear longitudinal third! the sole. However, the training element could extend with increasing height in the region of the front and / or rear longitudinal third of the sole.

If it is provided that the training element is arranged exclusively in the middle longitudinal third of the sole, so the training element touches neither the front nor the rear longitudinal third of the sole nor it projects into the region of the front or rear longitudinal third of the sole. It would be conceivable, however, that fasteners of the training element at the front or rear longitudinal third of the sole attack.

An embodiment of the invention provides that the training element - or, in the case of several training elements, their common envelope - has a greater height in a middle region of the training element or the envelope than in an edge region. The contour of the training element or the envelope is thus approximately curved or multi-stepped, which facilitates a rocking on the training element.

Of course, the Trainingseiement could also have a flat area of greatest height, which then drops straight and normal to the surface of the outsole to this point. But this has the disadvantage that a rocking or balancing hardly Ο is possible, because one would tilt forward or backward over the edge of the Trainingseiement at a weight shift forward or backward.

In order to ensure a sufficiently large training effect, the greatest height of the training element should be 3 to 200 mm, in particular 10 to 100 mm. Of course, the training effect at a height of only 3 mm will not be particularly great and training elements with 200 mm height are probably little more than to save space. Thus, the preferred height of the training element is most likely to be in the range of a few centimeters, that is 2, 3, 4, 5, 6, 7, 8, or 9 cm. It makes sense, too, to make the height dependent on the length of the sole, so that a similar training effect for different shoe sizes is present. For example, the height of the training element could amount to 1 to 60%, in particular 3 to 33%, of the length of the sole.

In order to further enhance the training effect, instability in the transverse direction of the sole can also be provided, for example by having the training element - or, in the case of several training elements, their common envelope - the greatest height in the middle of the sole, as seen in the transverse direction of the sole. The height of the training element or the envelope thus also varies in the transverse direction, wherein the height in the middle of the sole has a maximum. Again, the training element - or in the case of several training elements whose common envelope - can have a greater height in a central region of the training element or of the envelope than in an edge region. The contour of the training element or the envelope in the transverse direction can thus be approximately curved or multi-stepped, which facilitates rocking on the training element in the transverse direction.

It can be provided in general exactly one training element, which is easier in the production and attachment of the training elements on the sole. With only one training element whose contour can be made in a simple manner steadily, ie without edges. For a variant with several training elements speaks that - in comparison to the contour of a single training elements - with the same envelope material and thus weight can be saved. So it could be achieved with less material the same footprint. 7

If the training element is releasably connected to the sole, successively different training elements can be attached to the same sole, which differ approximately in size and / or structure and thus cause a different training effect. As releasable connections 5 are about screws, threads, magnets, Velcro, bayonet or the like in question. Of course, the training element may also be fixedly connected to the sole by being made in one piece with this or glued to it.

The training element or the training elements can be executed as a solid body 10, which has the advantage of easy production. Suitable materials include elastomers, such as rubber, which additionally contribute to the instability due to their elasticity. But it can also non-elastic plastics, wood or leather (in several layers) can be used. The individual materials can also be used in combination, for example in different layers. 15 If the training element or the training elements are each designed as a hollow body, material can be saved. If the hollow bodies are additionally elasticized, they can be filled with gas, whereby the degree of instability can be adjusted depending on the amount of gas. It can also be provided that the gas pressure can be changed continuously, for example by means of a valve.

In a single training element can be provided that the training element has the shape of a body of revolution, wherein the axis of rotation is aligned perpendicular to the sole. As a result, the training element has the same contour in all directions. When balancing 25 or rocking then results in the same movement, whether in the longitudinal direction of the sole is rocking (forward-back), in the transverse direction (left-right), or a direction in between (diagonally backwards obliquely). Thus, the training element may have the shape of a spherical segment, in particular a hemisphere.

Alternatively, a single training element may be provided to have different curvatures in different directions. Consider, for example, a segment of an ellipsoid that is not an ellipsoid of revolution, for example, one half of a lengthened lens. As a result, the swing behavior of the 3

Training element be different for different directions. This can be further increased in the example, if the main axes of the ellipsoid segment do not run in the longitudinal and transverse direction of the sole. Of course, several training elements can be arranged, which have an envelope with different curvatures in different directions.

In order to obtain a good training effect, it can also be provided that the training element contains one or more spring elements, such as cylinder springs. In this case, one or more spring elements may be arranged in an elastic body of the training element. But it can also be provided only one or more spring elements, each itself form a training element.

Alternatively or additionally, the training element may contain one or more damping elements or consist of one or more damping elements.

Finally, the subject invention includes a shoe by the sole according to the invention is connected to a shoe upper to a shoe.

WAYS OF CARRYING OUT THE INVENTION FIG. 1 shows a side view of a sole 1 with a hemispherical training element 3. The training element 3 directly adjoins the outsole 2 and is no longer than the medial longitudinal third 4 of the sole 1. The front longitudinal third 5 of the sole 1 and the rear longitudinal third 6 of the sole 1 are free of training elements or other elements attached to the outsole 2 attached are 20, such as heels. It would be conceivable, however, front and / or rear at the

Outsole lower elements (lower than the training element 3) provide that are elastic and support the return to the horizontal position of the sole 1.

From Fig. 2, which shows the sole of Fig. 1 in rear view, it can be seen that the training element 3 occupies approximately the entire width of the sole 1. From Fig. 3, which shows the sole of Fig. 1 in a bottom view, this is also seen.

The training element 3 may be formed as a solid body, such as wood, plastic, leather layers, rubber or a mixture thereof. It may be formed as an elastic hollow body, which is filled with gas, or in which

IC

Spring elements are arranged, see the corresponding cylinder springs 7 in Figs. 4 and 5.

The training element 3 does not have to be designed as a full hemisphere, but several training elements in the form of individual disks 10 may also be provided, the envelope of which results in a hemisphere. This is shown in Fig. 15, where the envelope is shown by dashed lines. The side view of the sole in Fig. 1 would also correspond to the side view of the embodiment of FIG. 15. Of course, the discs 10 could not only extend in the longitudinal direction of the sole 1, but also in the transverse direction or in any other direction. The training element 3 could also be replaced by a plurality of training elements in the form of columns 11, as shown in FIG. 16. This embodiment would then have a rasterfömniger arrangement of the columns 11, the same rear view as in Fig. 15. Of course, the columns 11 need not be arranged in grid form, they could also be arranged in mutually offset rows or in irregular shape 15. They may have round or angular cross-section. They could also be rounded at their free ends, which form the envelope.

With discs 10 or columns 11, of course, other shapes with other envelopes can be produced, such as block-shaped shapes as shown in Figs. 12-14. In FIGS. 4 and 5, the training element 3 is shown cut open so that its interior is visible. There are four cylindrical springs 7 arranged in a square, which are inclined away from the sole 1 to the outside. They could also be arranged parallel and perpendicular to the sole 1.

In the embodiment of Figures 6 and 7, a flat hollow training element 25 3 is provided, which is dargestelit each cut and in which four damping elements 8 are arranged in a square. They are inclined outwardly from the sole 1, but could also have a different inclination or be arranged normal to the plane of the sole 1 (ie vertically downwards in FIGS. 6 and 7).

Of course, spring and damping elements 6, 7 can be arranged even without a 30 enveloping training element 3. Or it could be any of the * 7 Ί

Spring and damping elements 6, 7 be provided with a coating, so that from the outside only individual columns 11, similar to in Fig, 16, can be seen.

FIG. 8 shows a shoe with a sole 1 according to FIGS. 1 to 7 and with a shoe upper 9. The shoe is designed as a loafer with lacing, 5 he could of course also be closed with Velcro straps or buckles. The shoe upper 9 could also be made open, consist only of bands, so that there is a sandal, which also allows a good grip with appropriate design.

9-11 show a sole 1 with two training elements in the form of pins 10 12, which are arranged along a diagonal to the longitudinal or transverse direction, as can be seen from the bottom view in Fig. 11. It is also conceivable that the pins 12 are arranged only at the middle longitudinal third 4, so they are connected only in this area of the sole 1 with this and there 15 touch, however, the free end of the pins 12, as seen in the longitudinal direction of the sole 1 protrudes over the middle longitudinal third 4, approximately due to an oblique pitch.

In such asymmetrically arranged training elements 12 can generally be provided that these are arranged equal or mirror-symmetrical for left and right foot. FIGS. 12-14 show an embodiment of the invention, where a single training element in the form of a rubber block 13 is arranged on the sole 1 in the middle longitudinal third. This has a square cross section, but could likewise have a rectangular, round or polygonal cross section. The lateral boundary surfaces are flat and normal to the plane of the sole 1. The 25 footprint of the rubber block 13 is rounded, the more the curvature is made, the greater the instability.

The embodiment according to FIG. 17 has a sole with an oversized training element 14 which protrudes beyond the middle longitudinal third part 4. The oversized training element 14 is thus arranged at the middle longitudinal third, that is, attached to it only there, but protrudes with increasing distance from the sole 1 also into the front and rear longitudinal thirds 5, 6 into it. The training element 14 may be rotationally symmetrical, but the standing surface could also be curved differently in different directions.

In Fig. 18, the training element 3, here again by way of example a hemisphere, although within the middle longitudinal third 4th However, it is not directly attached to the outsole, but by means of a fastener 15, the only in the front and rear longitudinal third 5, 6 attached to the sole 1, the training element 3 carries and is executed here in the form of a clamp. The fastening element 15 could also be attached to the outsole in the middle longitudinal third 4 or be supported there. The training element 3 could of course also have a different shape or be replaced by several training elements.
