Description

The present invention relates to a device for increasing the stability of the Movements with shoes for Tennis or the like Sports performed become.

It is known that depending on the exercised sporting activities it is essential to choose shoes the structurally best suited to facilitate the movements while they are wear the foot when exerting force to avoid contractions or incorrect ones Steps to avoid. A plateau-like support is known from EP-A-O 913 101, which falls within the scope of Art. 54 (3) EPC.

When practicing tennis, in particular the shoes have good stability of movements because the tennis player must be able to jump and run to move quickly in the square and in the Able to be the blows to intercept the enemy promptly and strike back.

In addition, but not less important, must Tennis shoes should be well buffered as they are good for catching the Need to secure shock when the foot touches the ground.

The outer part of the foot is the most severely affected area by the executed Movements of the tennis player are generated.

In fact, the player has to be able to move quickly and doing it continuously Sequence of lateral sliding movements and subsequent braking effects out.

Whoever practices this sport is certainly disadvantaged by shoes that are not safe for him the necessary stability lend because uncontrolled movements along with the resulting following considerable energy consumption are very dangerous, because of the possibility from sprained ankles or falls, or they can a risk with respect to future Form problems on the foot, knee or spine.

At the same time disadvantage shoes, who are not adequately buffered, the tennis player who, whenever he puts one foot on the floor, from one push to the other Ground is hit, which on him through the legs up in transferred to the spine becomes.

On the other hand, you use shoes back that simply with a midsole made of soft, shock-absorbing Material is provided, there is a risk that seriously the stability of your own movements impaired because the foot gets completely out of balance like it does comparable happens when you put your feet on a soft mattress jumps, which has a buffer effect, but a perfect one Loss of balance.

Purpose of the present invention is to provide a device which does the above Disadvantages of the conventional Avoids devices, especially by increasing stability Movements with shoes for Tennis and the like Sports.

In the context of this purpose is a Object of the present invention to provide a device which the overall structural design of the shoes does not disadvantaged or burdened in a way.

Another important purpose of present invention is to provide an apparatus which is simple, durable and wear-resistant.

Another purpose of the present The invention is to provide a device for increasing the stability of the movements, accomplished with shoes for Tennis or the like Sports that are easy with conventional equipment and machines can be manufactured.

Another important purpose of the present invention is a device for sports shoes to provide, which is able to optimally buffer the feet against bumps to ensure the floor.

This goal, these purposes and still others, which are better explained below, are achieved by a device according to the present invention to increase stability with Shoes for Tennis and the like Sports, characterized in that they have a plateau-like Prop contains which is substantially Y-shaped and has a first curved portion, suitable to the profile of the Heel area to follow, as well as a second section which is suitable to follow the outer profile of the foot and to a third section in the transverse direction that widens the midfoot area of said foot relates, said support in one downward area with a midsole made of shock absorbing material is connected to distribute the burden caused by this transfer the moving foot becomes.

Other properties and advantages of the present invention will become more apparent from the following detailed description of a preferred embodiment, which only by a non-limiting example in the accompanying Drawings is shown, of which

1 Figure 3 is a perspective view of a shoe provided with a stability enhancement device according to the present invention;

2 is a perspective disassembled view of the shoe from 1 ;

3 Figure 3 is a top view of a detail of the device shown in the preceding figures. With reference to the above figures, a shoe, particularly suitable for tennis, is generally designated by the reference number 10 denotes and contains an upper part 11 which with a sole 12 connected is.

The sole is formed by the connection a device for increasing stability, designated by the reference number 13 , with an outsole 14 of a type known per se.

In this case the outsole has 14 an overall bowl-shaped design, as it runs all around on its front part 15 and its rear part 16 with a raised edge 17 is provided to the corresponding sections of the top 11 take.

In this version, the outsole 14 Made from vulcanized rubber, but in other cases it can also be made of a different material as long as it has equivalent properties.

The device 13 contains a plateau-like support 18 , preferably made from a commercially known material with the trade name Kevlar, or in other cases from a material which has equivalent mechanical properties.

The support 18 is substantially Y-shaped and has a first curved section 19 , which, starting from an inner rear part 20 the sole of the foot 21 how the heel is shaped.

Starting from an outer rear part 22 the sole of the foot 21 , has the support 18 a second, substantially straight section 23 , which follows the outer profile of the foot until it reaches the outer metatarsal area 24 reached the same.

A third section 25 extends in particular from a central part of the second section 23 and widens transversely in relation to the second section 23 so that it has an overall forked shape and the inner metatarsal area 26 of the foot.

The plateau-like support 18 is particularly with a first curved section 19 provided which has a first surrounding edge 27 and a second surrounding edge 28 each of which is at right angles to the support 18 from the inner back part 20 and the outer rear part 22 the sole 21 extends from.

The plateau-like support 18 is also surrounded by a third border 29 completes which is monolithic along the profile of the outer metatarsal area 24 of the second section 23 runs.

The prop is in its active configuration 18 above a midsole 31 made of soft material, for example EVA, foamed polyurethane or a similar material, which acts as a buffer element.

In particular, the midsole is from the heel area 32 to the midfoot area 33 thicker and then tapers, leaving them in the remaining front area 34 is getting thinner.

• – sie sichert die korrekte Auflage des äusseren Teils des Fusses, welcher am intensivsten den Belastungen und dem Druck durch den Körper ausgesetzt ist, hervorgerufen durch plötzliche Beschleunigen oder Bremswirkungen, wobei sie absolute Bewegungsfreiheit lässt;
• – sie verteilt korrekt das Gewicht und die Belastungen, die durch den Fuss auf die Zwischensohle 31 übertragen werden, welche als stossdämpfendes Element wirkt, wodurch eine optimale Stabilität gesichert ist.

The plateau-like support 18 works especially with the midsole 31 together and performs two important functions:

• - It ensures the correct support of the outer part of the foot, which is most intensely exposed to the stresses and pressures caused by the body, caused by sudden acceleration or braking, while leaving absolute freedom of movement;
• - It correctly distributes the weight and loads placed on the midsole by the foot 31 transmitted, which acts as a shock-absorbing element, which ensures optimal stability.

The provision of the device 13 actually takes into account the two facts that during the contact of the foot with the ground, the entire weight of the body is completely discharged onto the midfoot area, which acts as a fulcrum when the foot bends, and from there to the rear part of the heel, as well as the special one Importance of lateral gliding, which is so common in tennis and where the outer part of the foot is the one most affected by the impact loads and braking effects.

In this way the shock absorbing effect is through the midsole 31 correctly stabilized thanks to the presence of the plateau-like support 18 ,

While it gives the inner part of the foot complete freedom that means the part that is at least affected by stress, the device according to the invention ensures a correct recording of the outside Partly, actually to absorb the stresses caused by the weight of the body and the muscle exercise of the athlete through shocks are caused.

The support and support is for the foot however in no way limiting as it is able to limit its adapt dynamic configuration without any constraint, being at the same time the correct cooperation with the midsole the shock absorbing Function ensures an advantageous distribution of the burden with the result of a considerable increase in stability.

In practice it could be observed that the purpose and objectives of the present invention are perfect have been achieved.

In particular, attention directed to the fact that the present invention is a device to increase stability Shoes for Tennis or the like Provides sports that in no way affect the overall structural Interpretation of the shoe disadvantaged or burdened.

It should also be noted that a device was provided which is of the structure is very simple and has good durability and wear resistance granted.

Another remarkable advantage that is certainly obtained by the present invention is related to the fact that a device to increase the stability of movements carried out with shoes for tennis or similar sports, which can be produced with conventional equipment and machines.

Another advantage is due to the fact that the device according to the invention is capable is an optimal buffering of the feet secure on the floor when belching.

The invention thus conceived is subject to numerous changes and variants within the scope of the attached Expectations.

The materials can be practical as well Dimensions as long as they are compatible with their use are any, depending on the requirements.

Where the technical mentioned in each claim Characteristics are followed by a reference number, so these reference numbers for the used for the sole purpose of increasing the comprehensibility of the claims, and such reference symbols have no limiting influence on the Interpretation of each element by using an example such reference numerals are made recognizable.
