Abstract

In a sports shoe 1 consisting of a shoe upper and a multilayer sole unit, usually consisting of an insole, midsole and an outsole, is the stiffness of the sole unit, which is divided into at least two areas, for example, forefoot VB and Mittelfussbereich MB or midfoot area MB and heel area FB , 16 is differently adjustable by means of a sliding element.

Description

The invention relates to a sports shoe according to the preamble of claim 1.

From the DE102007049520 As an example of a sports shoe an alpine ski boot is known in which the stiffness of the sole is adjustable. The necessary mechanism in the form of a tension member requires a lot of space and is particularly very expensive to manufacture. Another disadvantage is that the stiffness of the sole is uniformly changeable only for the entire sole region. This type of adjustment is in principle applicable only to ski boots. In addition to the space requirement is also due to the mechanics caused increased weight. For ski boots, which are already relatively heavy by nature, this is less crucial.

In addition, a separate tool is required to adjust the stiffness.

If the user does not carry the tool with them, the rigidity can not be adjusted.

From the documents US2011 / 0047816 . WO96 / 02157 and DE19853077 are different arrangements for adjustability of the stiffness of a sports shoe known, however, all of which are very complicated and difficult to use or complex to implement.

Often the desire for a changed stiffness of the shoe occurs immediately during a sporting activity.

The object of the invention is therefore to provide a sports shoe, which does not have the disadvantages mentioned above, which in particular allows a simple change in the stiffness of the shoe, which is only slightly heavier than a corresponding conventional sports shoe, which allows a tool-less change, which also targeted Change in stiffness allowed in certain foot zones and is easy and inexpensive to produce.

This object is achieved by the means specified in claim 1. Advantageous developments of the invention are specified in the subclaims.

The essential idea of the invention is, in a sports shoe consisting of a shoe upper, a midsole, an outsole and an insole, the stiffness of the shoe sole changeable in the application form.

This is achieved by incorporating between the (a) outsole and the midsole or between the (b) midsole and the insole or (c) directly into the midsole or (d) directly into the outsole a stiffening element which allows to stiffen at least two areas of the foot. By way of example, this stiffening can take place between the forefoot and the metatarsus and / or the metatarsus and the hindfoot.

The invention is explained in more detail with reference to an embodiment shown in the drawing.

• 1 Aufsicht auf einen erfindungsgemäßen Sportschuh teilweise aufgeschnitten.
• 2a Zwischensohle mit einem Versteifungselement in einer ersten Stellung (Versteifung zwischen Mittelfuss und Rückfuss)
• 2b Zwischensohle mit einem Versteifungselement in einer zweiten Stellung (Versteifung zwischen Vorfuss und Mittelfuss)
• 4-6 verschiedene alternative Ausgestaltungen eines Versteifungselements

Show it:

• 1 Top view of a sports shoe according to the invention partially cut.
• 2a Midsole with a stiffening element in a first position (stiffening between metatarsus and hindfoot)
• 2 B Midsole with a stiffening element in a second position (stiffening between forefoot and midfoot)
• 4-6 various alternative embodiments of a stiffening element

In 1 is a perspective view of a sports shoe according to the invention 1 with a
shown multilayer sole, the actual shoe, in particular the shoe upper and the shoe upper) is shown in dashed lines to allow the view into the interior of the shoe. The shoe has a profiled outsole 11 on. Inside the shoe is a midsole 12 arranged on the rests in the application, an insole or an insole, which is not shown here. The stiffening element, consisting of the basic body ( 14 ) and the sliding element ( 16 ), in this example, is positioned between midsole and insole (not shown in this figure).

In 2a a stiffening element is shown in plan view. It consists of a basic body 14 in the form of a typical insole or insole. On the main body 14 For stiffening the sole unit is a sliding element 16 fixed, along a sliding track 18 , which serves as a guide, is kept displaceable. The fixation takes place by means of two guide elements z. B. rivets. The shape of the sliding element 16 is designed so that it is independent of the shift position always within the outer contour region of the body 14 remains.

The shoe stiffening should not be understood only as a midsole. Rather, that can Shoe stiffening system can be understood as "module / technology / element / system" that can be incorporated into the midsole, but also part of the outsole (or between outsole and midsole) or as an insole or between insole and midsole can be placed.

The stiffening element is divided into three areas the forefoot area VB , the midfoot area MB and the heel area FB ,

In 2a is the sliding element 16 in the midfoot area MB and the heel area FB arranged and contributes in this area to increased rigidity (stiffening of the metatarsophrenic joints and the transition to the calcaneus).

In 2 B is the sliding element 16 in the forefoot area VB and the midfoot area MB heel VB arranged and contributes in this area to increased stiffness (stiffening of the toe and in particular the toe joints).

It is also conceivable, the sliding element 16 to arrange MB in the metatarsal area in order to generate increased rigidity here.

In the case shown, the stiffening element is removable. The stiffening element can also be integrated firmly in the sports shoe. In this case, the sliding element 16 z. B. by means of an accessible from the outside of the sports shoe lever adjustable.

The function of the invention is explained in more detail below.

In order to change the stiffness of the sole, the stiffening element, after the insole has been removed or insole, can be removed from the interior of the shoe.

By moving the sliding element 16 from the heel area FB towards the forefoot, the stiffness of the shoe can be used for the different foot areas FB . MB be varied. If the user wishes increased stiffness in the forefoot area VB (Metatarsophalageal area), so he needs the sliding element 16 move forward to the stop.

In particular, cyclists often want increased stiffness in the forefoot area for better power transmission. The change in the stiffness of the shoe can be done quickly, easily and without tools.

For a better rolling when walking, the sliding element 16 back in the heel area FB be pushed back.

Another essential idea of the invention is to make the rigidity of the sole variable in use in a sports shoe consisting of a shoe upper and a multi-layered sole unit, usually consisting of insole, midsole and outsole.

This is achieved by incorporating between the (a) outsole and the midsole or between the (b) midsole and the insole or (c) directly into the midsole or (d) directly into the outsole a stiffening element which allows to stiffen at least two areas of the foot. By way of example, this stiffening can take place between the forefoot and the metatarsus and / or the metatarsus and the hindfoot.

The stiffening element consists of the main body 14 and the sliding element 16 , where on the main body 14 a guideway 18 is provided in the at least one on the sliding element 16 provided guide element FE intervenes. The contour of the sliding element 16 in the heel area FB of the sports shoe 1 is designed so that it matches the outer contour of the main body 14 in the heel area FB matches and in the forefoot area VB extends substantially within the outer contour of the body. It may also mean that the stiffening element is narrower or refers only to the medial part of the foot / floor plan.

In addition to the original stiffening element, which covers the entire plantar foot area, it is possible to derive three other basic plantar surface forms:

1. (1) Reduzierung der Fläche des Versteifungselements in der Sagittalachse (distal - proximal) (4): Beispielsweise können nur zwei Fussbereiche durch das Versteifungselement versteift werden. In 4 wird beispielsweise die Bewegung der Zehengrundgelenke mittels der Versteifung im Vor- und Mittelfuß limitiert. Da der Rückfussbereich hier nicht durch das Versteifungselement abgedeckt wird, kann die Sohleneinheit in diesem Bereich besser deformieren und trägt somit zu einer besseren Dämpfung respektive Komfortverbesserung bei.
2. (2) Reduzierung der Fläche des Versteifungselements in der Transversalachse (medial - lateral) (5): Beispielsweise kann nur die mediale Fussfläche durch das Versteifungselement versteift werden. In 5 wird beispielsweise ausschliesslich die mediale Fussfläche aller drei Fussbereiche (Vor-, Mittel- und Rückfussbereich) durch das Versteifungselement abgedeckt. Da die laterale Fussfläche hier nicht durch das Versteifungselement abgedeckt wird, kann die Sohleneinheit in diesem Bereich besser deformieren und trägt somit zu einer besseren Dämpfung respektive Komfortverbesserung bei.
3. (3) Reduzierung der Fläche des Versteifungselements sowohl in der Sagittalebene (distal - proximal) als auch Transversalachse (medial - lateral) (6): Dieses Beispiel für ein Versteifungselement entspricht der Kombination aus (1) und (2) und beinhaltet die bereits oben angeführten Charakteristiken.

Various other alternative embodiments of the invention with a reduced or partial stiffening element or stiffening system are in the 4 - 6 shown.

1. (1) Reduction of the area of the stiffening element in the sagittal axis (distal - proximal) ( 4 ): For example, only two foot areas can be stiffened by the stiffening element. In 4 For example, the movement of the toe joints is limited by the stiffening in the fore and midfoot. Since the rear foot area is not covered here by the stiffening element, the sole unit can deform better in this area and thus contributes to a better cushioning or comfort improvement.
2. (2) reduction of the area of the stiffening element in the transverse axis (medial - lateral) ( 5 ): For example, only the medial footing can be stiffened by the stiffening element. In 5 For example, only the medial foot area of all three foot areas (front, middle and back foot area) is covered by the stiffening element. Since the lateral foot surface is not covered here by the stiffening element, the sole unit can deform better in this area and thus contributes to a better cushioning or comfort improvement.
3. (3) reduction of the area of the stiffening element both in the sagittal plane (distal - proximal) and the transverse axis (medial - lateral) ( 6 ): This example of a stiffening element corresponds to the combination of (1) and (2) and includes the characteristics already mentioned above.

Other mixed forms or combinations with respect to the plantar surface forms, which are associated with a reduction of the plantar surface form, are conceivable.
