Definitions

  • the present invention refers to a footwear item provided with an interchangeable outsole.
  • a variety of sports footwear items, in particular football and similar boots and shoes are known nowadays to be provided with an interchangeable outsole provided with a number of spikes.
  • These interchangeable outsoles may be featuring a variety of spike types and patterns differing from each other as far as both the number and the size and the actual arrangement of the spikes themselves over the interchangeable outsole are concerned. In this way, the possibility is given for a same shoe to be used with the most appropriate outsole to suit the actual conditions and characteristics of the playground.
  • a footwear item having a midsole for the interchangeable outsole to be applied thereto.
  • Such midsole comprises a raised flange extending along a longitudinal edge between the extremities of the same midsole
  • the interchangeable outsole comprises a longitudinal raised flange that extends between the extremities of the same interchangeable outsole along a side which - under operating or use conditions - lies opposite to the side along which there extends the flange of the midsole.
  • the longitudinal raised flange of the midsole and the longitudinal raised flange of the outsole are able to interact, i.e.
  • the interchangeable outsole is in fact provided with a through-bore for a screw to be fitted thereinto, whereas the midsole is provided - again at each extremity thereof - with corresponding receptacles, into which the attachment screws are able to be tightened so as to firmly hold the interchangeable outsole in position onto the shoe.
  • a user is in fact required to provide for the interchangeable outsole to be first of all positioned in a very accurate manner onto the midsole, so that the position of the through-bores in the interchangeable outsole will perfectly and exactly fit with the position of the receptacles in the midsole, otherwise it would clearly prove practically impossible for the screws to be inserted and engage the respective receptacles.
  • a further drawback of the above-cited prior-art footwear item lies in the fact that the screws and the related receptacles are provided in correspondence to the toe portion and the heel portion of the shoe, i.e. exactly at those sites which are exposed to the greatest force and stress exerted by the foot of the wearer when practicing his/her sports activity. Under the circumstances, it can therefore be most readily appreciated that the receptacles and the shank of the screws fitted thereinto to engage said receptacles are quite likely to cause the wearer's foot to suffer a considerable amount of inconvenience, up to jeopardizing the actual ability of the wearer to perform adequately.
  • Still another drawback derives from the fact that, in order to ensure that the screws are firmly and reliably secured into their receptacles, the same receptacles must be provided in the midsole down to an adequate depth and this fact makes it necessary for the midsole to be provided with a correspondingly great thickness.
  • the practical result is to have the position of the foot raised by an excessive extent relative to the shoe and the playground, in a manner that is certainly not correct in view of the sports activity being performed.
  • a further drawback lies in the fact that the through-bores in the interchangeable outsole are provided at the toe portion and the heel portion thereof and this sets definite limits - on these regions - as far as the positions are concerned, in which spikes may conveniently be provided and arranged on the interchangeable sole.
  • another purpose of the present invention is to provide an interchangeable outsole that is capable of being firmly attached to the footwear item in an extremely simple and quick manner.
  • Yet another purpose of the present invention is to provide a footwear item with interchangeable outsole featuring a fastening mechanism that ensures a maximum extent of safety and reliability.
  • Still another purpose of the present invention is to provide a footwear item with interchangeable outsole, which is inherently simple in its construction and capable of being manufactured at competitive costs using generally and readily available tools and machinery.
  • the footwear item with interchangeable sole as generally indicated with the reference numeral 1 there, comprises an upper adapted to receive and accommodate a wearer's foot, a midsole 3 that is permanently associated to said upper, an interchangeable outsole 4, and coupling means provided to removably secure said interchangeable outsole 4 to said midsole 3.
  • the interchangeable outsole 4 comprises a front portion 5 and a rear portion 6 that are associated to each other via at least a flexure strip 7, 8 adapted to allow the interchangeable outsole 4 to both flexibly bend and spring back into an outstretched position thereof.
  • the midsole 3 comprises a front peripheral undercut 9 and a rear peripheral undercut 10, which are adapted to receive a toe extremity 11 of the front portion 5 and a heel extremity 12 of the rear portion 6, respectively.
  • the front portion 5 and the rear portion 6 are adapted to bend at the flexure strip 7, 8 so as to cause the interchangeable outsole 4 to bend into a curved form to thereby enable said extremities 11, 12 of the interchangeable outsole 4 to be fitted into the respective peripheral undercuts 9, 10 of the midsole 3, said extremities 11, 12 being then caused to firmly engage said undercuts 9, 10 when said interchangeable outsole 4 is eventually allowed to spring back.
  • the midsole 3 defines a bottom surface 13 for the interchangeable outsole 4 to be able to be attached thereto, and - at least at the extremities thereof, i.e. the toe extremity and the heel extremity - it comprises a peripheral edge 14 that protrudes from the bottom surface 13 of the midsole 3.
  • a peripheral edge 14 At said toe extremity and heel extremity of the midsole, such peripheral edge 14 defines a folded portion 15 that extends parallel to said bottom surface 13 separately, i.e. spaced therefrom so as to integrally form the front peripheral undercut 9 and the rear peripheral undercut 10.
  • the peripheral edge 14 extends all along the whole periphery of the midsole 3 so as to delimitate a seat, i.e. a region adapted to receive and accommodate the interchangeable outsole 4.
  • the interchangeable outsole 4 is comprised of at least a front portion 5 and a rear portion 6, which are adapted to engage the front peripheral undercut 9 and the rear peripheral undercut 10 of the midsole 3, respectively.
  • the front portion 5 and the rear portion 6 of the interchangeable outsole 4 define a toe extremity 11 and a heel extremity 12, respectively, which are adapted to be fitted into the respective peripheral undercuts 9, 10 to have the interchangeable outsole 4 applied and attached to the midsole 3.
  • the toe extremity 11 and the heel extremity 12 form each a kind of tang adapted to be received into the undercuts 9, 10 when the interchangeable outsole 4 is applied on to the midsole 3.
  • the front portion 5 and the rear portion 6 are joined to each other via at least a flexure strip 7, 8, at which said front portion 5 and said rear portion 6 are able to flex, i.e. be bent relative to each other so as to elastically bring the interchangeable outsole 4 into a curved configuration to thereby reduce the longitudinal dimension thereof.
  • This enables the afore-cited extremities 11, 12 of the interchangeable outsole 4 to be fitted into the respective peripheral undercuts 9, 10 of the midsole 3.
  • the flexure strip 7, 8 is further adapted to cause the front portion 5 and the rear portion 6 to elastically flatten out again, so that the interchangeable outsole 4 springs back into the outstretched state thereof, in which said extremities 11, 12 of the interchangeable outsole 4 are therefore able to keep being fitted into and engaging the respective undercuts 9, 10 of the midsole 3, in such manner that the interchangeable outsole 4 is fitted into the peripheral edge 14 and in contact with the bottom surface 13 of the midsole 3.
  • the interchangeable outsole 4 is capable of being applied on to the midsole.
  • the interchangeable outsole 4 comprises first coupling means 16 adapted to reversibly, i.e. releasably engage second coupling means 17 provided in the midsole 3 to quickly lock/unlock the interchangeable outsole 4 to/from the midsole 3.
  • said first coupling means 16 and said second coupling means 17 are provided at a front position and a rear position on the interchangeable outsole 4 and the midsole 3, respectively, i.e. substantially in correspondence of the toe portion and the heel portion.
  • first coupling means 16 and said second coupling means 17 may be provided in other positions, as well.
  • they can be provided at a middle position on the interchangeable outsole 4 and the midsole 3, respectively, i.e. in correspondence to the plantar arch of the foot of the wearer.
  • the interchangeable outsole 4 comprises a middle portion 18, which is associated to the front portion 5 via a first flexure strip 7, and associated to the rear portion 6 via a second flexure strip 8.
  • the interchangeable outsole 4 is made in the form of a unitary, single-piece structure, in which there are provided two notches, flutes or similar indentations in order to achieve said flexure strips 7, 8.
  • definite reductions in the thickness of the interchangeable outsole 4 enable said flexure strips 7, 8 to be formed integrally therewith.
  • the flexure strips 7, 8 constitute preferred bending axes of the interchangeable outsole 4, by means of which the same outsole is enabled to reversibly bend into a curved form and flatten out into its outstretched state.
  • the front portion 5 and the rear portion 6 are adapted to flex relative to the middle portion 18 at the first flexure strip 7 and the second flexure strip 8, respectively, so as to bring the interchangeable outsole 4 into a curved form and, as a result, reduce the length of the same outsole in such a manner as to enable the toe extremity 11 of the interchangeable outsole 4 to be fitted into the front peripheral undercut 9 of the midsole 3, and the heel extremity 12 of the interchangeable outsole 4 to be fitted into the rear peripheral undercut 10 of the midsole 3.
  • such flexure strips 7, 8 are adapted to elastically bias back the front portion 5 and the rear portion 6 of the interchangeable outsole 4, so as to allow the same interchangeable outsole 4 to spring back into the outstretched state thereof.
  • the extremities 11, 12 are adapted to engage the respective undercuts 9, 10.
  • the front portion 5, the rear portion 6 and the middle portion 6 of the interchangeable outsole 4 are adapted to be in contact with the bottom surface 13 of the midsole 3, while the peripheral edge 14 thereof is adapted to contain the interchangeable outsole 4 along the sides thereof.
  • the front portion 5 and the second portion 6 comprise said first coupling means 16 to releasably engage said second coupling means 17 provided in corresponding positions on the midsole 3, i.e. on the front and rear portions of the midsole 3.
  • the first coupling means 16 of the interchangeable outsole 4 and the second coupling means 17 of the midsole 3 form a kind of bayonet coupling device.
  • first coupling means 16 comprise a male coupling member 19, which is accessible from outside to be able to be actuated by a user
  • second coupling means 17 comprise a female coupling member 20, which is adapted to receive and reversibly engage said male coupling member 19 by virtue of the bayonet mount mechanism.
  • coupling or locking devices may be used in the present invention, as well.
  • these may be automatic securing devices with complementary snap-fitting elements or even fastening devices with threaded, i.e. screw elements.
  • the male coupling member to be provided on the midsole and the female coupling member to be provided on the interchangeable outsole.
  • the male coupling member 19 is adapted to be accommodated in a containment body 21 that is integrally defined by the front portion 5 and the rear portion 6 of the interchangeable outsole 4, whereas the female coupling member 20 consists of a hollow seat or receptacle 22 protruding from the bottom surface 13 of the midsole 3.
  • such hollow receptacle 22 is integrally defined by the midsole 3 and, as a result, is provided to form a unitary single-piece construction with the same midsole 3.
  • the male coupling member 19 defines a first extremity 23, by means of which it is adapted to be rotatably associated to the containment body 21, and a second extremity 24, which is provided withy a pair of mutually opposed tabs 25.
  • the first extremity 23 is accessible from the outside of the containment body 21 so as to be capable of being actuated with a tool in order to rotate the male coupling member 19.
  • the hollow receptacle 22 is provided with an aperture 26 that is so shaped as to be complementary to the second extremity 24.
  • the mutually opposed tabs 25, which are oriented in a given direction, are adapted to pass through the aperture 26 so as to enable the second extremity 23 of the male coupling member 19 to be inserted into the hollow receptacle 22 of the female coupling member 20.
  • the mutually opposed tabs 25 are adapted to engage the hollow receptacle 22, thereby locking the male coupling member 19 firmly in position in the female coupling member 20 and securing the interchangeable outsole 4 to the midsole 3.
  • the hollow receptacle 22 is provided internally with cogs or similar detents 27 adapted to cooperate with the mutually opposed tabs 25 to define a locking position, in which the second extremity 24 of the male coupling member 19 is locked, i.e. positively retained inside the hollow receptacle 22 of the female coupling member 20, and a release or disengagement position, in which the second extremity 24 of the male coupling member 19 is capable of being removed from the hollow receptacle 22 of the female coupling member 20 to release and set the male coupling member free.
  • the interchangeable outsole 4 may preferably comprise a plurality of pulling or gripping members 28, such as spikes or the like, which project downwards from the front portion 5 and the rear portion 6 thereof, so as to be able to be used in practicing a variety of sports activities, e.g. football. It is of course possible for the shoe or boot to be provided with a set of interchangeable outsoles, each one of them featuring a different configuration or arrangement of the spikes for a most appropriate utilization thereof on different playgrounds and under varying conditions of the playground itself.
  • a plurality of pulling or gripping members 28 such as spikes or the like
  • the user or wearer has the rotational position of the male coupling member 19 duly checked so as to make sure that the mutually opposed tabs 25 are oriented in the appropriate direction in view of the ability of the second extremity 24 of the male coupling member 19 to be inserted through the aperture 26 of the female coupling member 20.
  • the user will then flex the front portion 5 and the rear portion 6 relative to the middle portion 18 so as to bend the interchangeable outsole 4 into a curved configuration and, as a result, reduce the longitudinal dimension thereof.
  • the user By exerting a pressure upon the middle portion 18 of the interchangeable outsole 4, the user now helps the first flexure strip 7 and the second flexure strip 8 to elastically bias back the front portion 5 and the rear portion 6, respectively, thereby causing them to flatten out.
  • the interchangeable outsole 4 moves into contact with the bottom surface 13 of the midsole 3, while arranging itself along the peripheral edge 14 thereof.
  • the toe extremity 11 and the heel extremity 12 get engaged in the respective undercuts, whereas the mutually opposed tabs 25 of the second extremity 24 of the male coupling member 19 get inserted - through the aperture 26 - in the hollow receptacle 22 of the female coupling member 20.
  • inventive footwear item with interchangeable outsole as described above may of course be the subject of a number of modifications and may be embodied in a number of different manners without departing from the scope of the present invention, wherein all afore-cited details may furthermore be replaced with technically equivalent elements.
