Description

COVERI~IG F.LEMENT PA2TICULARLY AP~LICABLE TO SOCCEP~ SHOES
The present invention relates to a covering element particularly applicable to soccer shoes.
As known, ~occer shoes substantially have a configuration which, generally speaking, can be likened to 5 that of a normal ~hoe, in particular in the front region, which is the region most used to kick the ball.
Accordingly, the configuration of the shoe has a rounded shape which in the upper median part is interrupted by the presence of the shoe fastening lace, whiçh in 10 practice creates an irregular surface which protrudes with respect to the remainder of the shoe.
It is also known that it is particularly important for a soccer player to be able to direct tha ball with the maximu~ possible accuracy; the region of impaat between ~he 15 shoe and the ball is consequently decisive.
~ he European patent EP 0 104 196 describes a covering for an item o~ footwear, for example for soccer players, which is substantially constituted by a part which covers the top region of the upper and has means for coupling, in a 20 downward po~ition, below a portion of the edge of the item o~ footwear itself, leaving free the region affected by the sole.
In this embodiment, the covering simply has the function o~ defining a region for impact between the foot 25 and ~he ball with an improved friction coefficient dete~mined by the material of which the body is made, but does not allow to define regions which allow to direct the hall ~ore accurately when kicking.
By means of the described embodiment/ the connection ~"` 2~7~ -between the covering body and the item of footwear furthermore does not seem able to adeguately withstand the impact and mutual sliding forces which occur when the ball is struck.
The patent application DE 38 37 504 describes an item of footwear which is provided, directly on the upper, with pads or similar elements which allow to define particular shapes for the outer surface, according to ~he different regions of impact with the ball.
This embodiment has the disadvantage of si~nificantly increasing the weight of the item of footwear, so that it is not suitable ~or being used by a soccer player for the duration of the match.
The type of surface used furthermoxe does not allow one 15 to be in the best conditions for hitting the ball d~ing a soccer match~
The aim of the invention is indeed to solve ~he above described problem by providing a covering element particularly applicable to soccer player shoes which allows 20 to create on the outer surface of the shoe regions which are shaped according to the specific use for soccer playing and allow to extend the useful region for impact between the ball and the shoe in all the various types of kick which are normally performed.
Within the scope of the above aim, a particular object of the invention is to provide a covering element which has an extremely reduced weight, so as to avoid unduly in~rea~ing the weight of the shoe and producing fatigue for the user.

With reference to the above figures, the covering element particularly applicable to soccer shoes, according to the invention, comprises a body, generally indicated by the reference numeral 1, which is advantageously made of a 10 substantially elastic material which is constituted by synthetic or natural rubber or by materials which have similar characteristics.
Preferably, from experimental tests which have been conducted it has been ~ound that it is advantageous to use a 15 mix of natural or synthetic rubber with resilien~e characteristics equal to, or greater than, those of natural rubber, with a hardness comprised between 15 and 70 short A;
in the base rubber, the ~ix has a content of more than 5~ o~
natural rubber or synthetic rubber with resilience 20 characteristics egual to, or greater than, those of natural rubber.
A chemical product known as "factice" and constituted by vulcanized oil is furthermore provided in the base rubber in a percentage comprised between 1 and 25~.
With respect to the base rubber, it is then possible to introduce plasticizing charges smaller than 250~ with respect to the base rubber.
Said body 1 defines, in its front p~rtion, an inner ca~ity 2 in which the front part of a soccer shoe, generally 2~7~l~
indicated by the reference numeral 3 and generically illustrated in figure 5, can be inserted.
It should be noted that the con~iguration o~ said cavity is not provided by means of a shape which is 5 complementary to that of the shoe, but ~y means of a different shape, so that the body 1 assumes th~ requir~d outer shape when the shoe is inserted.
Lateral bands 5 extend fr~m the front part o~ the body 1, where said cavity 2 is defined, and taper substantially 10 toward the rear region 6 which is arranged so as to embrace the heel of the shoe. An elongated narrow portion 8 extends between the rear region 6 and the lower part 7 of the body 1 and widens at said sole 7, where holes 11 can be defined for the passage o~ the studs 12 o~ the shoe.
In the front region, said body 1 defines, on its outer surface, a subetantially planar front surface which is arranged proximate to the perpendicular with respect to the plane of arrangement of the lower part 7 and has in any case an outer surface which is inclined by no more than 30 with 20 respect to the part 7.
At said front surface Z0, the body 1 has a thickness, in its central part, which is comprised between 0.8 and 7 mm, and its radius of curvature with respect to the upper surface 30 is advantageously comprised between 1 and 30 mm 25 in khe various cross-sectionsO
The blending radius betw~en the front part ~nd ~he part 7 is internally comprised be~ween 0.1 and 5 mm, i.e. it is substantially a sharp edge, whereas a radius comprised between 1 and 6 mm is provided externally.
The upper surface 30 is s~bstantially cDncave ~nd, as 8 2 ~
more clearly illustrated in figure 14, is arranged asy~metrically with respect to the median axis of the shoe;
more precisely, its width, on the outer side of the ~oot, is greater by an amount comprised between 1 and 30% with 5 respect to the distance between the centerline and the inner side of the foot; this entails, in a plan view, a different radius between the inner upper edge and the out r upper edge.
The body furthermore has an outer lat~ral surface 40 o which is inclined, with respect to the plan~ which is perpendicular to the part 7, by an angle which is comprised between 5 and 50; said angle becomes more acute ~rom the tip toward the rear part, where the outer lateral surface 40 defines a cusp 41 which extends toward the upper and rear 15 part.
The outer lateral sur~ace affects a shoe portion comprised between 20 and 50%, and advantageously it has a concave shape 44 in the upper portion with a radius of curvature o~ more than 50 mm and a convex shape 45 at the 20 cusp, with a radius of more than 35 mm, whereas in the lower part 46 of the cusp it again has a convex shape with a radius comprised between 15 and 100 mm.
The outer lateral surface divaricates ~rom the upper surface, where it forms a cusp which has an upper radius 25 which must not exceed 5 mm.
An inner lateral surface 50 is furthermore provided on the inner lateral surface of the body 1 and substantially has a shape whicn matches the configuration of the shoe with a reduction of the thickness of the body 1 to zero at the 0 rear part, so as to respect in the best manner the only 9 2~
currently valid impact surface of a soccer shoe, i.e. the concavity of the inner instep.
The upper front surface is delimited, with respect to the inner and outer lateral surfaces, by two predominantly 5 raised apexes 80 and 81 which have, in transverse cros~-section, a radius substantially comprised between 0.1 and 10 mm; the inner apex 81, i.e. the apex which i5 interposed between the upper front surface and the outer lateral surface, is furthermore arranged at a lower level with lO respect to the outer apex 80 by an amount h which is advantageously compriRed between 1 and 4 mm.
Observing the sectional views in detail, it can be seen that the cross-section illustrated in figure 8, substantially proximate to the tipl shows that the body 15 has lateral thicknesses comprised between 0.5 and 7 mm, w:ith a substantially constant thickness until the radii of the inner cross-section start to vary in order to define the two apexes arranged outside the upper surface, where the thickness of the rubber can be comprised between 2 and 10 20 mm.
The radius of the curvature of the outer lateral sur~ace varies between 10 and 150 mm, whereas the inner radius of the outer apex is comprised between 2,5 and 40 mm.
The radius of curvature of the concave front surface is Z5 comprise~ between 40 and 200 mm on the outer surface and advantageously comprised between 40 and 300 mm on the inner surface.
It should be noted that by means of this arrangement, the outer apex is relativPly higher ~han ~he inner apex, so 30 as to lower the trajectory of the ball in so-called half-... . .
, - :
2~7~
overhead kicks, which normally tend to make the ball go too high.
This difference in height bl-tween ~he apexes is considerably important, since it allows to better direct the 5 trajectory of the ball.
Observing the cross-section of iEigure 9, it can be seen that the inner curvature radii for radiusing between the outer surfaces and the front upper surface are comprised between 2.5 and 70 mm, wher as the curvature radii of the 10 apexes and of the inner and outer surfaces are substantially similar to the preceding figure.
The outer lateral surface is inclined, in a transverse cross-section, by 10 to 50 with respect to the part 7 or bottom, whereas the inner lateral surface has an inclination 15 comprised b~tween 0 and 40.
In the cross-section illustrated in figure 10, the curvature radius of the apex of the outer lateral surface increases until it reaches 80 mm.
At the cross-section of fiyure 11, which substantially 20 illustrates a median portion of the shoe, the body 1 is practically interrupted in the lower part to leave free for impact the so-called "inner instep", which already presently constitutes an ideal surface for ball impact.
~he end part of the outer lateral surface is 25 furthermore substantially arranged in this region.
As can ba seen from figure 12, which corresponds approximately to the ~oot instep, the front upper surface becomes substantially planar and the body 1 has a uniform thickness substantially comprised between 2 and :L0 mm.
In the subsequent cross-section o~ ~igure 13 it can be 11 2~
seen that the body 1 has a surface with a convex radius which radiuses with the lateral constant-thickness surfaces.
According to the cross-section of figure 7, it is shown that the connection between the lower portion and the rear 5 portion is defined by means of an edge which is preferably sharp or in any case has a radius not exceeding 10 mm.
It should also be noted that the length of the body is calculated so that it is smaller than the length of the shoe on which it will be applied by an amount comprised lo between lo and 4D%, so that by exploiting the elasticity of the material it is possible to subject the body 1 to tension so as to keep it tightly secured to the shoe.
Furthermore, in order to facilitate ~oot transpiration, it is possible to provide holes, indicated by 85, which 15 substantially affect the reg:ions of the front part of the body 1 which covers the shoes, thus obtaining the advantage of facilitating foot transpiration and of fll~ther reducing the weight of said body 1.
: Grooves, generally indicated by the reference numeral 20 go, are advantageously defined on the various impact surfaces defined; on the upper concave surface, said grooves are inclined from the rear left to the front right, for the right shoe, whereas they are inclined backward from the rear right to the front left for the left shoe. The outer lateral 25 surface of the right shoe has grooves from the rear top to the front bottom both on the right foot and on the left foot; similarly, on the inner lateral surface of the left shoe and of the right shoe, the grooves are inclined from the rear top to the front bottom for both shoes.
The inclination of the grooves or knurlings :imparts, at 12 2~7~
the moment of impact, a trajectory component to ~he ball which tends to lower the trajectory it~elf, consequently correcting the typical defects currently observed with the trend of the ball to rise with respect to playing field at 5 the moment of impact.
From what has been described above it can thus be seen that the invention achieves the proposed aim and objects, and in particular the fact is stressed that by applying the body 1 to the shoe it is possible to impart a precise 10 direction to ~he ball by means of a careful study of the ergonomic movements of a soccer player, in all the conditions of a match, providing ~our suhstantial impact surfaces and keepiny substantially unchanged the only concave sur~ace currently pressnt in the shoe, i.e. the 15 inner instep surface.
The body 1, as described, furthermore provides the advantage of having an absolute and persistent adhçsion of the covering to the shoe, an excellent compliance with the problem related to the excess weight, which could in part 20 cancel out the advantages offered by the provision of an ideal surface, and the problem of using a material suitable for the specific purpose, such as rubber or in any case elastomeric products or thermoplastic materials, which would have scarce foot ventilation if they were not provided with 25 perforations distributed uniformly on their surfaces, is ~urthermore solved.
Covering a shoe with a covering, besides improving the characteristics of impact between the shoe and ~he ball, also gives ~he great advantage of protecting the shoe from 30 wear.
13 2 ~
Another extremely important aspect is furthermore constituted by the fact that the inner cavity is not shaped complementarily with respect to the shoe, so that in practice channels substantial~y fill~ed with air are created 5 at the apex regions ~nd act as an element which allows a better adaptation to the surface during the impact of the ball and furthermore act as cushioning element in case of collisions between players At the moment of impact.
~ he invention thus conceived is susceptible to numerous lo modifications and variations, all of which are within the scope of the inventive concept.
All the details may furthermore be replaced with other technically equivalent elements.
In practice, the materials employed, although the best 15 results have been obtained with the above described materials, as well as the contingent shapes and dimensions, may be any according to the requirements.

In the front region, said body 1 defines, on its outer surface, a subetantially planar front surface which is arranged proximate to the perpendicular with respect to the plane of arrangement of the lower part 7 and has in any case an outer surface which is inclined by no more than 30 with 20 respect to the part 7.
At said front surface Z0, the body 1 has a thickness, in its central part, which is comprised between 0.8 and 7 mm, and its radius of curvature with respect to the upper surface 30 is advantageously comprised between 1 and 30 mm 25 in khe various cross-sectionsO
The blending radius betw~en the front part ~nd ~he part 7 is internally comprised be~ween 0.1 and 5 mm, i.e. it is substantially a sharp edge, whereas a radius comprised between 1 and 6 mm is provided externally.
The upper surface 30 is s~bstantially cDncave ~nd, as 8 2 ~
more clearly illustrated in figure 14, is arranged asy~metrically with respect to the median axis of the shoe;
more precisely, its width, on the outer side of the ~oot, is greater by an amount comprised between 1 and 30% with 5 respect to the distance between the centerline and the inner side of the foot; this entails, in a plan view, a different radius between the inner upper edge and the out r upper edge.
The body furthermore has an outer lat~ral surface 40 o which is inclined, with respect to the plan~ which is perpendicular to the part 7, by an angle which is comprised between 5 and 50; said angle becomes more acute ~rom the tip toward the rear part, where the outer lateral surface 40 defines a cusp 41 which extends toward the upper and rear 15 part.
The outer lateral sur~ace affects a shoe portion comprised between 20 and 50%, and advantageously it has a concave shape 44 in the upper portion with a radius of curvature o~ more than 50 mm and a convex shape 45 at the 20 cusp, with a radius of more than 35 mm, whereas in the lower part 46 of the cusp it again has a convex shape with a radius comprised between 15 and 100 mm.
The outer lateral surface divaricates ~rom the upper surface, where it forms a cusp which has an upper radius 25 which must not exceed 5 mm.
An inner lateral surface 50 is furthermore provided on the inner lateral surface of the body 1 and substantially has a shape whicn matches the configuration of the shoe with a reduction of the thickness of the body 1 to zero at the 0 rear part, so as to respect in the best manner the only 9 2~
currently valid impact surface of a soccer shoe, i.e. the concavity of the inner instep.
The upper front surface is delimited, with respect to the inner and outer lateral surfaces, by two predominantly 5 raised apexes 80 and 81 which have, in transverse cros~-section, a radius substantially comprised between 0.1 and 10 mm; the inner apex 81, i.e. the apex which i5 interposed between the upper front surface and the outer lateral surface, is furthermore arranged at a lower level with lO respect to the outer apex 80 by an amount h which is advantageously compriRed between 1 and 4 mm.
Observing the sectional views in detail, it can be seen that the cross-section illustrated in figure 8, substantially proximate to the tipl shows that the body 15 has lateral thicknesses comprised between 0.5 and 7 mm, w:ith a substantially constant thickness until the radii of the inner cross-section start to vary in order to define the two apexes arranged outside the upper surface, where the thickness of the rubber can be comprised between 2 and 10 20 mm.
The radius of the curvature of the outer lateral sur~ace varies between 10 and 150 mm, whereas the inner radius of the outer apex is comprised between 2,5 and 40 mm.
The radius of curvature of the concave front surface is Z5 comprise~ between 40 and 200 mm on the outer surface and advantageously comprised between 40 and 300 mm on the inner surface.
It should be noted that by means of this arrangement, the outer apex is relativPly higher ~han ~he inner apex, so 30 as to lower the trajectory of the ball in so-called half-... . .
, - :
2~7~
overhead kicks, which normally tend to make the ball go too high.
This difference in height bl-tween ~he apexes is considerably important, since it allows to better direct the 5 trajectory of the ball.
Observing the cross-section of iEigure 9, it can be seen that the inner curvature radii for radiusing between the outer surfaces and the front upper surface are comprised between 2.5 and 70 mm, wher as the curvature radii of the 10 apexes and of the inner and outer surfaces are substantially similar to the preceding figure.
The outer lateral surface is inclined, in a transverse cross-section, by 10 to 50 with respect to the part 7 or bottom, whereas the inner lateral surface has an inclination 15 comprised b~tween 0 and 40.
In the cross-section illustrated in figure 10, the curvature radius of the apex of the outer lateral surface increases until it reaches 80 mm.
At the cross-section of fiyure 11, which substantially 20 illustrates a median portion of the shoe, the body 1 is practically interrupted in the lower part to leave free for impact the so-called "inner instep", which already presently constitutes an ideal surface for ball impact.
~he end part of the outer lateral surface is 25 furthermore substantially arranged in this region.
As can ba seen from figure 12, which corresponds approximately to the ~oot instep, the front upper surface becomes substantially planar and the body 1 has a uniform thickness substantially comprised between 2 and :L0 mm.
In the subsequent cross-section o~ ~igure 13 it can be 11 2~
seen that the body 1 has a surface with a convex radius which radiuses with the lateral constant-thickness surfaces.
According to the cross-section of figure 7, it is shown that the connection between the lower portion and the rear 5 portion is defined by means of an edge which is preferably sharp or in any case has a radius not exceeding 10 mm.
It should also be noted that the length of the body is calculated so that it is smaller than the length of the shoe on which it will be applied by an amount comprised lo between lo and 4D%, so that by exploiting the elasticity of the material it is possible to subject the body 1 to tension so as to keep it tightly secured to the shoe.
Furthermore, in order to facilitate ~oot transpiration, it is possible to provide holes, indicated by 85, which 15 substantially affect the reg:ions of the front part of the body 1 which covers the shoes, thus obtaining the advantage of facilitating foot transpiration and of fll~ther reducing the weight of said body 1.
: Grooves, generally indicated by the reference numeral 20 go, are advantageously defined on the various impact surfaces defined; on the upper concave surface, said grooves are inclined from the rear left to the front right, for the right shoe, whereas they are inclined backward from the rear right to the front left for the left shoe. The outer lateral 25 surface of the right shoe has grooves from the rear top to the front bottom both on the right foot and on the left foot; similarly, on the inner lateral surface of the left shoe and of the right shoe, the grooves are inclined from the rear top to the front bottom for both shoes.
The inclination of the grooves or knurlings :imparts, at 12 2~7~
the moment of impact, a trajectory component to ~he ball which tends to lower the trajectory it~elf, consequently correcting the typical defects currently observed with the trend of the ball to rise with respect to playing field at 5 the moment of impact.
From what has been described above it can thus be seen that the invention achieves the proposed aim and objects, and in particular the fact is stressed that by applying the body 1 to the shoe it is possible to impart a precise 10 direction to ~he ball by means of a careful study of the ergonomic movements of a soccer player, in all the conditions of a match, providing ~our suhstantial impact surfaces and keepiny substantially unchanged the only concave sur~ace currently pressnt in the shoe, i.e. the 15 inner instep surface.
The body 1, as described, furthermore provides the advantage of having an absolute and persistent adhçsion of the covering to the shoe, an excellent compliance with the problem related to the excess weight, which could in part 20 cancel out the advantages offered by the provision of an ideal surface, and the problem of using a material suitable for the specific purpose, such as rubber or in any case elastomeric products or thermoplastic materials, which would have scarce foot ventilation if they were not provided with 25 perforations distributed uniformly on their surfaces, is ~urthermore solved.
Covering a shoe with a covering, besides improving the characteristics of impact between the shoe and ~he ball, also gives ~he great advantage of protecting the shoe from 30 wear.
13 2 ~
Another extremely important aspect is furthermore constituted by the fact that the inner cavity is not shaped complementarily with respect to the shoe, so that in practice channels substantial~y fill~ed with air are created 5 at the apex regions ~nd act as an element which allows a better adaptation to the surface during the impact of the ball and furthermore act as cushioning element in case of collisions between players At the moment of impact.
~ he invention thus conceived is susceptible to numerous lo modifications and variations, all of which are within the scope of the inventive concept.
All the details may furthermore be replaced with other technically equivalent elements.
In practice, the materials employed, although the best 15 results have been obtained with the above described materials, as well as the contingent shapes and dimensions, may be any according to the requirements.
