Definitions

  • the present invention relates to a sole for sports shoes, to a shoe equipped with this sole and to a method for obtaining this sole.
  • the sports footwear may be used for practicing a sport or for driving motorcycles and similar vehicles.
  • boots which users can use during sporting performances, be they races or use of a motorcycle on the road or track.
  • These motorcycle boots have a sole and an upper that are reinforced in some points, for example in the points where the upper of the boot is placed on the ground during use of the motorcycle.
  • motorcycle boots which are provided with a metal reinforcing element to be applied to the outer side area of the boot itself, for example at the malleolus of the user's foot, in order to reduce wear and rubbing of the upper of the boot in this area when the user rests his foot on the ground, for example when making turns on the road or on the track with the motorbike.
  • motorcyclists especially when they ride on paved roads or circuits - often place their foot on the ground while the motorbike is moving to have an additional point of support which gives stability and greater riding safety.
  • This practice determines wear of the part of the boot that is placed on the ground (i.e. in particular the external front side part, of both the sole and the upper) such that the boot often needs to be replaced on a recurring basis, or repaired at these points.
  • these zones are often reinforced precisely to avoid drawbacks of this type.
  • the object of the present invention is to provide a sole for a sports shoe, such as for example a motorcycle boot, which is resistant in the points of contact with the ground during driving, which is simple to replace once worn and that it can be used by motorcyclists of any category.
  • An object of the present invention is to improve the state of the prior art.
  • Another object of the present invention is to provide a sole for sports shoes which is particularly useful for motorcycle shoes.
  • a further object of the present invention is to provide a sole equipped with a protective element capable of protecting the sole and/or upper of the sports shoe.
  • a further object of the present invention is to provide a sole equipped with a removable or interchangeable protective element, which allows it to be replaced on the basis of need or on the basis of the level of wear.
  • a sole for a sports shoe according to claim 1 is provided.
  • a further object of the present invention is to provide a sport shoe equipped with a sole with at least one protective element, capable of protecting and reinforcing the sole and/or the upper of the sports shoe itself.
  • a further object of the present invention is to provide a method for obtaining a sole.
  • the sole according to the present invention is a sole for sports shoes, which can be used for practicing a sport or for driving motorcycles and similar vehicles and/or comprise especially a boot for use on a motorcycle or similar vehicle.
  • the term “lower” means an element placed lower down or facing the ground.
  • the term “superior” means an element placed higher or facing upwards.
  • front refers to an element or position substantially corresponding to the area of the toes of a user's foot.
  • rear refers to an element or position substantially corresponding to the area of the heel of a user's foot.
  • longitudinal means an axis or plane that goes substantially from the toes to the heel of a user's foot while “transverse” means an axis or plane that goes substantially from side to side of a user's foot, generally perpendicular to the "longitudinal" axis or plane.
  • the sole 1 comprises a lower surface 2, for example shaped like a tread, suitable during use to face downwards or towards the ground.
  • the sole 1 also comprises an upper surface 3 opposite the lower surface 2 and adapted during use to be facing towards a foot of a user or facing upwards or adapted to be placed in contact with a midsole or insole.
  • the sole 1 has a front area F, located substantially at the toes of the user's foot, a rear area P, located substantially at the heel of the user's foot, and a central area C, located between the front F and the rear area P.
  • the sole 1 also defines an external lateral portion, facing the outside of the user's foot, and an internal lateral portion, facing the other foot.
  • the sole 1 further comprises a thickness S.
  • the thickness S corresponds to the distance between the lower surface 2 and the upper surface 3.
  • the thickness S can be variable passing from the front area F to the rear area P of the sole 1 itself. In particular, as can be seen from the figures, the thickness S can be less at the front area F and can be greater at the rear area P of the sole 1.
  • the sole 1 can have a raised edge 4 at one or more areas thereof, for example in particular at the rear area P.
  • the raised edge 4 has a substantially perpendicular shape with respect to the general extension of the sole 1 and/or its upper surface 3, particularly in the rear area P. Furthermore, the raised edge 4 forms a sort of lateral containment wall which accommodates the user's foot, especially his heel.
  • the extension of the raised edge 4 is substantially upwards, considering the sole 1 resting on the ground in use. Furthermore, this extension has a measure such as to wrap in height at least half or less than half or more than half of the user's heel or a measure substantially corresponding - in the rear area - to the lateral thickness of the toes of the user's foot (or to the their height, considering the foot resting on the ground or on the sole 1).
  • the sole 1 comprises a sole element 6.
  • the sole element 6 can comprise, in at least one version, a hollow portion 5.
  • the sole element 6 substantially has the overall shape of the sole 1 and therefore the lower surface 2 and the upper surface 3 of the sole 1 itself can be identified for it.
  • the hollow portion 5 is placed substantially at the front area F, and possibly also in the central area C, of the sole 1. In detail, this hollow portion 5 is placed at the outer front lateral area of the sole 1 and substantially at the user's toe area.
  • the hollow area 5 is located at the outer front lateral area of the sole 1 and in the area of the user's toes or at the outer front lateral area of the sole 1 and in the area of at least one or at least two or at least some of the user's toes.
  • the hollow portion 5 is placed substantially at the toe of the sole 1, extending also in the outer lateral front part.
  • This hollow portion 5 has a depth of thickness S1 lower than the thickness S of the sole 1 and/or of the sole element 6 and/or lower at least than the thickness S of the sole 1 at its front area F. Therefore, this hollow portion 5 determines the formation of a part of the surface 6b of the sole element 6 of smaller size than the overall size of the sole 1 itself and having a thickness S2 smaller than the thickness S of the sole.
  • the thickness S2 of the surface part 6b has a thickness substantially equal to the difference between S and S 1.
  • the surface part 6b in at least one version of the invention, is smooth, i.e. not affected by the tread pattern present in the remaining part 6a of the sole 1 and/or of the at least one sole element 6, considering that the remaining part 6a of the sole element 6 corresponds to the lower surface 2 of the sole 1 without the surface part 6b which is affected by the hollow portion 5 and/or by the protective element 7.
  • the sole 1 advantageously comprises at least one protective element 7.
  • the protective element 7 is able to give protection to at least a portion of the sole 1 and/or the upper of the sports shoe object of the present invention. Thanks to this, the sports shoe is protected during use by the user, for example when the motorcyclist places his foot on the ground when cornering or braking or in general during movement of the motorbike. Furthermore, the user is more secure in performing these movements.
  • the protective element 7 also makes it possible to provide greater strength to the sole 1 and/or to the upper, so as to help the same to resist the shocks and friction exerted for example by the road, the track or in general by the ground, when the sports shoe is placed on the ground while the motorcycle is being used.
  • the at least one protective element 7 is positioned at a front area F, located substantially at the user's toes, and in an outer front lateral area of the sole 1.
  • the at least one protective element 7 is positioned at the outer front lateral area of the sole 1 and in the area of the user's toes or at the outer front lateral area of the sole 1 and in the area of at least one or at least two or at least some of the toes of the user's foot.
  • the at least one protective element 7 is interposed, optionally with the surface part 6b, between the user's toes and the ground.
  • the at least one protective element 7, in the version in which the hollow portion 5 is present, can be positioned and/or housed at least partially at the hollow portion 5 itself. Furthermore, the protective element 7 is removable or interchangeable since, once it is worn or damaged, it can be easily replaced by the user.
  • this removability also allows the user to vary this element at will, to adapt the sports shoe to different uses or even for aesthetic reasons.
  • the sole 1 is a composite sole comprising the at least one sole element 6 and the at least one protective element 7.
  • the at least one protective element 7 actually replaces the metal plates (or metal sliders) which are usually placed in the upper at the lateral external part of the classic motorcycle boot, at the user's toes, and in particular at the side (or metatarsal) of the little toe, for protection and to increase the resistance of the boot in that point.
  • the protective element 7 allows to cover and therefore also protect the front part or toe of the sole 1 itself or at least part thereof. Therefore, overall, the at least one protective element 7 is able to protect the sole and/or the upper in the most critical points, such as those which are placed on the ground when cornering or braking, for example during the movement of a motorcycle, is capable of absorbing shocks and reducing wear and tear of the sole itself and/or of the upper associated with it.
  • the at least one protective element 7 has, in at least one version, a substantially irregular U shape. In particular, this conformation can be found by observing its transversal trend.
  • the at least one protective element 7 has an internal surface 8, suitable in use to be facing and placed in contact with the sole element 6 (or better with its hollow portion 5) and/or with the upper of the shoe, and an external surface 9, opposite to the internal surface 8 and/or adapted during use to face the ground and/or to come into contact with the same.
  • the external surface 9 can be walked on. This means that at least part of the external surface 9 of the at least one protective element 7 rests on the ground during use and the user can "walk" on it.
  • the external surface 9 can, at least in part, reproduce the tread pattern present in the remaining part 6a of the sole 1.
  • the at least one protective element 7 comprises a base portion 10, which can for example have a shape substantially corresponding to that of the hollow portion 5 of the sole 1.
  • the base portion 10 extends in a substantially corresponding way to the front area F, and possibly also to the central area C, of the sole 1. In detail, this base portion 10 is placed at the outer front lateral area of the sole 1 and substantially in the area of the toes of the user.
  • the base portion 10 is placed substantially at the toe of the sole 1, extending also in the external lateral front part.
  • the base portion 10 has a thickness S3 substantially corresponding to the thickness S1 of the hollowed portion 5. In this way, in use, once the at least one protective element 7 has been positioned at the hollowed portion 5, the external surface 9 at the base portion 10 and the remaining part 6a of the sole 1, are substantially flush.
  • the overall lower surface 2 of the sole 1, therefore, in its assembled or ready-to-use version, is formed by the external surface 9 placed at the base portion 10 and by the remaining part 6a of the sole element 6.
  • the surface part 6b in fact, is placed in contact with the internal surface 8 of the base portion 10 of the at least one protective element 7 and therefore in use is not visible and/or is not involved in contact with the ground.
  • the at least one protective element 7 also comprises a raised portion 11.
  • the raised portion 11 has a substantially fin-like shape which departs without interruptions from at least one area of the base portion 10, at least substantially upwards.
  • this raised portion 11 covers at least part of the front part or toe and the outer front lateral part of the sole 1 and/or of the sports shoe which is equipped with this sole.
  • This raised portion 11 has an at least slightly curved shape, so as to follow the profile of the lateral and/or perimeter part of the sole 1 and/or of the part of the upper which is closest to the sole 1.
  • this raised portion 11 has a substantially convex shape while, considering the internal surface 8, this raised portion 11 has a substantially concave shape, suitable for housing the corresponding portion of the toe and lateral outer front part of the sports shoe, or at least their edge portions.
  • the at least one protective element 7 assumes a substantially U-shaped conformation, considering its transversal shape.
  • the base portion 10 has in plan view a substantially irregular shape and/or similar to an inclined rectangle and/or a trapezoid or a triangle.
  • the recessed portion 5 is delimited perimetrically by:
  • the hollow portion 5 has a substantially irregular plan shape and/or similar to an inclined rectangle and/or a trapezoid or a triangle, completely similar and corresponding to that of the base portion 10 of the at least one protective element 7.
  • the first section 10a is placed at the first segment 5a, the second section 10b at the second segment 5b and the third section 10c at the third segment 5c.
  • the first segment 5a extends approximately from a substantially central portion of the sole 1 radially towards the position of the big toe (or substantially in the direction of the big toe) of the user's foot
  • the second segment 5b extends approximately from this substantially central position of the sole 1 (from which the first segment 5a departs) transversally towards the outer side of the sole 1 or at least slightly towards the rear area P of the sole 1
  • the third segment 5c joins the distal end of the first segment 5a (that placed externally or at the perimeter of the sole approximately in the area or in the direction of the big toe) and the distal end of the second segment 5b (that placed externally or at the perimeter of the sole in the area of the outer side), following the curved and/or arched pattern of the sole 1 and/or of the user's foot.
  • the raised portion 11 departs from the third section 10c in a substantially continuous manner.
  • the raised portion 11 departs from this third section 10c following a substantially upward or vertical trend (considering the version in use or worn by the sole 1) which can continue, according to at least one version of the invention, folding at least partially over the user's toes and/or towards the area corresponding to the user's toe nails. According to this version, therefore, the raised portion 11 at least partially envelops the user's toes and/or reaches as far as the area corresponding to the user's toe nails.
  • the lateral and frontal positioning of the at least one protective element 7 can be better appreciated in the exemplary figures 8 and 9 which represent a motorcycle boot equipped with a sole 1 according to the present invention.
  • the width of the base portion 10 and/or the width of the fold of the raised portion 11 above the upper of the sports shoe can vary according to the needs, even possibly with the same width of the base portion 10.
  • the raised portion 11 can have, at the toe of the sole 1, an almost exclusively vertical pattern while, at the outer front lateral portion of the sole 1, a curved pattern which at least partially covers also the upper of the shoe.
  • the raised portion 11 takes on a substantially wavelike shape or in any case a different extension on the basis of the area considered.
  • the thickness of the at least one protective element 7 can be constant along its entire extension or it can be variable and/or it can be greater at the thickness S3 of the base portion 10 with respect to the thickness of the raised portion 11 or vice versa.
  • the thickness of the raised portion 11 is greater than the thickness S3 since, at the edge or profile of the shoe, there is a need for greater resistance to wear and better cushioning, with respect to the bottom support area of the sole.
  • the at least one protective element 7 comprises stiffening means 12, at at least part of its internal surface 8.
  • the stiffening means 12 comprise at least one rib.
  • This at least one rib can be positioned for example at the third section 10c of the base portion 10. In this way, this area has a greater internal thickness which gives better resistance to impact and wear during use.
  • the stiffening means 12 can present a series of ribs, for example positioned according to a given pattern.
  • This pattern can be in rows and columns, in parallel rows or columns, in boxes, to form elements in relief with a polygonal section, in cells or honeycombs (as illustrated for example in figure 7 ), in a lattice, irregular, to various conformations, etc.
  • these stiffening means 12 are positioned at the internal surface 8 of the raised portion 11. However, they can also be present only at the base portion 10 or substantially in the entire internal surface 8.
  • the base portion 10 and the raised portion 11 of the protective element 7 are made in one piece and/or are integrated with each other without interruptions.
  • the material which constitutes the sole 1 and/or the at least one element of the sole 6 can be rubber or a compound suitable for complying with the EN 13634 standard.
  • the at least one protective element 7 can be made of the same material as the sole element 6 or in the same material as the sole element 6, however having a greater degree of stiffness than that of the material of the sole element 6, or in a thermoplastic polymer (TPU), or in at least one of nylon, Kevlar or other plastic materials, glass fiber, carbon fiber, composite materials, or in a suitable material.
  • TPU thermoplastic polymer
  • the material of the at least one protective element 7, however, is selected from materials which guarantee resistance to impacts and/or wear but at the same time do not excessively break the sports shoe when it is placed on the ground in use, for example when cornering or braking a speeding motorcycle.
  • the sole 1 could be made in one piece, i.e. the protective element 7 and the sole element 6 could be made joined, for example by means of a suitable mould.
  • the hollow portion 5 could not be present, since the hollow space delimited by it would be directly filled by the material of the sole element 6 and of the protective element 7, without distinction between them or without solution of continuity.
  • several protective elements 7 can be provided, each having a different degree of stiffness, for example equal to or greater than the stiffness of the material constituting the sole element 6.
  • the present invention also refers to a kit for making a sole 1 comprising at least one sole element 6 and at least two protective elements 7, wherein each protective element 7 has a different stiffness and/or size than that of the other or subsequent protective element 7.
  • a kit for making a sole 1 comprising at least one sole element 6 and at least two protective elements 7, wherein each protective element 7 has a different stiffness and/or size than that of the other or subsequent protective element 7.
  • the material of the at least one sole element 6 can also be varied according to the needs of use and employment of the sole 1 or of the sports shoe equipped with the sole 1.
  • the present invention also relates to the protective element 7 per se and to a method for assembling a sole 1.
  • This method involves the following steps: providing at least one sole element 6, providing at least one protective element 7, positioning the at least one protective element 7 at a front area F, located substantially at the toes of the foot user, and an outer front lateral area of the sole 1, assembling this at least one protective element 7 with the at least one sole element 6 in order to obtain a sole 1.
  • the step of positioning and/or assembling comprises a step of superimposing at least a base portion 10 of the at least one protective element 7 on a hollow portion 5 of the at least one sole element 6.
  • the step of positioning and/or assembling may optionally include a step of bringing the external surface 9 of the base portion 10 flush with the remaining part 6a of the sole element 6, so as to obtain a lower surface 2 for the sole 1 continues and essentially without interruption. In this way the sole 1 is comfortable for the user while walking.
  • the assembling step can also comprise removably constraining the at least one protective element 7 and the at least one sole element 6 by means of removable coupling means 13.
  • the removable coupling means 13 comprise, in at least one version of the invention, at least one hole 13a positioned in the hollow portion 5, at least one opening 13b positioned in the base portion 10 of the at least one protective element 7 and at least one screw or a nail 13c, which can be housed or fixed at the at least one hole 13a and the at least one opening 13b.
  • the hole 13a can also be understood as a seat.
  • the at least one opening 13b in fact, in use, is superimposed on the at least one hole 13a, so as to together create a seat for housing at least one screw or at least one nail.
  • the method according to the present invention therefore, provides for bringing the at least one hole 13a into overlap with the at least one opening 13b (step visible, for example, in figure 10 ) and a step for inserting and/or constraining and/or fixing and/or coupling and/or screwing the at least one screw or at least one nail 13c (or in general the removable coupling means 13), so as to determine the removable assembly of the at least one protective element 7 with the at least one sole element 6.
  • the removable coupling means 13 comprise at least one hole 13a positioned in the hollow portion 5 and at least one screw or nail 13c integral with the base portion 10 of the at least one protective element 7 and which can be housed or fixed at the at least one hole 13a or vice versa.
  • the removable coupling means 13 can have other configurations such as, for example, seats and pins, dovetail joints, interlocking couplings, buttonholes and buttons, magnetic coupling means, etc., able to determine the necessary bond between sole element 6 and protective element 7, without risk of disassembly during use. Furthermore, once the protective element 7 has been assembled with the sole element 6, the removable coupling means 13 are flush with the lower surface 2 of the sole 1 or slightly hollow with respect to the same, so as not to interfere with the foot support of the user.
  • the removable coupling means 13, in at least one version, are configured in number of four holes 13a, four openings 13b and four screws or nails 13c. A different number can of course be provided, without departing from the scope of protection of the present invention.
  • the removable coupling means 13, in at least one version, are placed along the first segment 5a of the hollow portion 5 and/or the first section 10a of the base portion 10 of the at least one protective element 7 and/or at the third segment 5c of the hollow portion 5 and/or of the third section 10c of the base portion 10 of the at least one protective element 7.
  • the removable coupling means 13 can be placed at the raised portion 11 of the at least one protective element 7 for fastening to the front area F of the sole 1 and/or to the toe of the upper of the sports shoe.
  • the removable coupling means 13 can also be placed in other areas of the base portion 10 and of the hollow portion 5 of the sole 1.
  • the removable coupling means 13 are positioned exclusively in the lower part of the sole.
