-1- FLASH, ERO FOOTBALL BOTYOblast technology

BACKGROUND OF THE INVENTION The present invention relates to a slip, in particular a shoe sling.

Background Art

As is known, football shoes have an arrangement that is generally similar to normal shoes, especially in the toe region, which is the most used for ball intervention. Accordingly, the football boot has a rounded shape which is interrupted in the upper middle by the presence of a lace-up, which in practice creates an irregular surface that protrudes relative to the remaining portion of the shoe.

It is also known that it is particularly important for football players to be able to direct the ball with the utmost precision.

The area of impact between the shoe and the ball is therefore critical.

European Patent Specification No. 0 104 196 discloses a slip-over shoe shoe, for example for a football player, which essentially consists of a portion that covers the top of the upper and has a means of support, in a lower position, below the edge of the football itself, leaving the sole affected area free. In this embodiment, the sleeve simply has the function of defining the impact area between the foot and the ball at an increased friction coefficient determined by the material from which the body is made, but does not allow to define areas that allow the ball to be directed precisely to the intervention.

By means of the described embodiment, the connection between the buckle and the piece of footwear does not appear to be able to withstand the corresponding impact and the shear forces that are produced during the impact.

DE 38 37 504 discloses a piece of footwear which is provided directly on the upper with a washer or the like, which allows to define special shapes for the outer surface depending on the different areas of collision with the ball.

This embodiment has the disadvantage that it considerably increases the weight of the shoe, so it is not suitable for use by a football player after a match.

Furthermore, the type of surface used does not allow the player to be in the best ball position for the duration of the football match. SUMMARY OF THE INVENTION The object of the present invention is to solve the aforementioned problem of making a slip especially applicable to footwear of football players, which would make it possible to create areas on the outer surface of the shoe that are customized for use in playing football and to extend the useful area for interplay between the ball and the shoes of all the different types of ball action that are normally performed. It is a further object of the present invention to provide a slipper which has a marginally reduced weight to prevent undesirable increases in shoe weight and thus user fatigue. It is a further object of the present invention to provide a slip that allows a significant improvement in contact between the shoe and the ball at the time of the ball action and with the following possibility to give the ball the desired rotation to control its path. It is a further object of the present invention to provide a slipper which, in addition to improving ball hit accuracy, would form a shoe protection, eliminate shoe wear caused by ball hits and act as a shoe protection element for use on wet ground, since water and mud cannot adhere to the shoe. since the control practices that are retained with conventional shoe pieces are omitted. . Furthermore, it is an object of the present invention to provide a slip that can be easily and comfortably mounted on a piece of shoe with additional provision of an exquisitely valuable and secure connection, even when performing a great deal of force.

An exemplary embodiment of the invention

The invention will now be described in detail with reference to the drawings. The invention according to the invention comprises a body 1 which is preferably made of a substantially resilient material consisting of artificial or natural rubber or materials having similar properties. Preferably, it has been found from the experimental tests that it is advantageous to use a mixture of natural or artificial rubber with elasticity equal to or higher than that of natural rubber, with a hardness ranging from 15 to 70 short A. a blend of contents of more than 51 natural or artificial rubber with elasticity equal to or greater than that of natural rubber. In the basic rubber, a chemical product known as "faktis" composed of vulcanized oil in a proportion of 1 to 25% by weight is further included. The body 1 defines in its front part an inner cavity 2 in which the front part 2 of the football shoe is schematically shown in FIG.

It should be noted that the shape of the cavity 2 is not a precise complementary shape, but is different, so that the body 1 has the desired outer face when the shoe is inserted therein. From the front of the body 1, the side strips 2 extend from the edge of the cavity 2 and converge substantially towards the rear region 6, which is arranged to surround the heel of the shoe. A narrow strip 8 extends between the rear region 2 and the sole 2 of the body 1 and extends at the sole 2 to provide openings 11 for passage through the nail 12. In the front region, the body 1 has on its outer surface a substantially planar front surface 20 which is Almost perpendicular to the sole 2 and having in any case an outer surface with respect to the sole 2 does not have an inclination greater than 30 °. On said front surface 20, the body 1 has a thickness of 0.8 to 7 mm in its middle part and its radius of curvature relative to the top surface 30 is preferably in different cross-sections in the range of 1 to 30 mm.

The radius of transition between the front and the sole 2 is within the range of 0.1 to 5 nm, i.e. it is essentially a sharp edge, while the outer side is a radius of 1 to 6 mm.

The top surface 30 is substantially concave and is shown in more detail in FIG. It is arranged asymmetrically with respect to the central axis of the rod. More precisely, its width on the outside of the foot is a larger part equal to 1 to 30% of the distance between the middle line and the inner side of the foot. This causes different radii between the inner top edge and the outer top edge in a top view. Furthermore, the body 1 has an outer side surface 40 that is inclined relative to a plane that is perpendicular to the sole 2 at an angle of 5 to 50 °. Said angle is progressively sharper from the tip to the rear where the outer side surface 40 forms the apex 41 that runs over the top and rear.

The outer side surface 40 covers a portion of the shoe from 20 to 50% and preferably has a concave shape 44 at the top with a radius of curvature greater than 50 mm and a convex shape 45 at the top 41 with a radius of curvature greater than 35 mm. The bottom 46 of the top 41 again has a convex -6-shape 45 with a radius of curvature of between 15 and 100 mm ·

The outer side surface 40 extends from the upper surface 40, forming a vertex having an upper radius of not more than 5 mm ·

Further, an inner side surface 50 and a substantially shaped shape is formed on the body 1, which corresponds to the configuration of the shoe when the body thickness 1 is lowered to the rear to best respect the commonly used surface of the ball with a football boot, that is, the inner surface of the inner. instep ·

The upper face surface is separated with respect to the inner side surface 50 and to the outer side surface 40 by two predominantly protruding peaks 80 and 81 which, in cross section, have a radius of curvature of substantially 0.1 to 10 mm. An inner vertex 81 which is positioned between the upper anterior surface and the outer lateral surface 40 of the dish is arranged at a lower level with respect to the outer vertex 80o, which is preferably 1 to 4mm.

By examining the cross sectional images in detail, it can be seen that the cross section shown in FIG. 8, which is close to the tip, shows that the body 1 has a side thickness of 0.5 to 7 mm substantially constant, while the radii of the inner cross section starting to change to define two vertices arranged outside the top surface, the length of the rubber may be from 2 to 10 mm.

The radius of curvature of the outer side surface 40 varies from 10 to 150 mm, while the inner radius of the outer top 80 is from 2.5 to 40 mm ·

The radius of curvature of the concave front surface is from 40 to 200mm on the outer surface and preferably from 40 to 300mm on the inner surface.

It should be noted that by this arrangement the outer peak 80 is relatively higher than the inner peak 81, so that the ball path decreases the so-called positionally-shaped interventions, which normally appear to incline the ball too high.

This difference in height between the peaks of 80.81 is significant because it allows the ball path to be better aligned.

By observing the cross-section in FIG. S, it can be seen that the curvature curves inside between the outer surfaces and the upper front surface are from 2.5 to 70 mm, while the curvature radii of the inner surface and outer surface 80.81a are substantially similar to those in previous picture.

The outer side surface 40 is at an angle of from 10 to 50 ° with respect to the sole 2 while the inner side surface 50 -7- is inclined at an angle of 0 to 40 °. In the cross-section shown in FIG. 10, the radius of curvature of the top of the outer side surface 40 is up to SO mm. In the cross-section shown in FIG. 11, which is substantially the middle portion of the shoe, the body 1 at the bottom is practically discontinued to leave the so-called " inner instep " balls »

In addition, the end portion of the outer side surface 40 is substantially aligned in this region.

As can be seen from FIG. 12, which corresponds approximately to the foot instep, the anterior upper surface becomes substantially planar and the body 1 substantially thick to substantially 2 to 10 mm. 13, the body 1 has a convex radius surface that extends into the side surfaces of a constant thickness. It can be seen from Fig. 7 that the connection between the narrow band 8 and the rear face 6 is formed by an edge which is preferably sharp or has a radius of not more than 10 mm.

It should be noted that the length of the body 1 is calculated to be finer than the length of the shoe to which the slip is to be slipped, by 10 to 40%, so that by utilizing the elasticity of the material the body 1 can be subjected to the tension state for its tight attachment to the shoe . Further, in order to facilitate the ventilation of the foot, it is possible to form the apertures 83 substantially in the regions of the front portion of the body 1, which covers the shoe, so that a favorable leg ventilation is obtained and the weight of the body 1 is further reduced. Grooves 90 are preferably formed in the various above-mentioned ball hit surfaces. On the upper concave surface, the grooves 90 are inclined from the rear left to the front right side of the right slip, while being tilted backward from the back right to the front left side of the left slip. The right side slip outer side surface 40 has grooves 90 inclined from the rear upper to the front lower side of the right and left slips. Similarly, on the inner side surface 50 of the right and left slices, the grooves 90 are inclined from the rear upper to the front lower side.

The slope of the grooves 90 at the time of the ball hit this or a track component that attempts to reduce the track itself and thus correct the typical errors commonly observed by trying to climb the ball relative to the pitch at the time of intervention. it achieves the intended purpose and purpose, and it is particularly important that putting the body 1 on the shoe allows the ball to give a precise direction on the basis of careful study of the football player's ergonomic movements in all football match conditions by creating four substantial ball-hit points and the substantially unchanged only bulging surface commonly found in the shoe, i.e. the inner instep surface, is retained.

Furthermore, the described body 1 has the advantage of having an absolute and permanent adhesion to the shoe and an excellent solution to the problem of excess weight, which could suppress the benefits obtained by creating an ideal surface, and the problem of using a material of suitable prospective rubber like or in some instances of elastomers or thermoplastics that would cause poor leg ventilation if they were not provided with apertures spaced evenly on their surfaces.

Covering the shoe with a slip has the great advantage of protecting the shoe from wear, in addition to improving the characteristics of the shoe hit by the shoe.

Another extremely important fact is that the inner sleeve of the invention according to the invention is not shaped in addition to the shape of the flap, so that in practice air inflated channels are formed in the region of the apexes, which act as an element that allows better adaptation surface during ball hit, and acts as a cushion in the event of a collision between football players at the time of hit.

The present invention may be subject to a variety of variations without departing from the spirit of the invention. Further, all building elements can be replaced by other, technically uniform elements. Other materials may be used in practice, although the best results have been obtained with the above materials. Also, the dimensions and shapes may be altered according to particular requirements.
