Definitions
- the present invention relates to a footwear intermediate element suitably produced to assure an effective and excellent coupling of said intermediate element to the footwear sole.
- said invention is advantageously applied to shoes, boots, amphibious and military shoes.
- Said intermediate element is mainly applied in the field of footwear industries.
- the intermediate element is inserted by pressure inside of the shoe sole, said sole being provided with a suitable recess or a preformed seat to receive it.
- said intermediate element is retained inside of its predetermined seat by means of a cork sole which is arranged throughout said intermediate element.
- said form of embodiment has the main drawback to cause a relevant deformation of the external edges of the sole to which said intermediate element is coupled.
- the intermediate element is not suitably retained inside of its seat, a relevant deflection of the external sole edges occurs, the sole thickness of the central zone being not suitable for rigidly supporting the user's weight.
- said deflection does not only affect the aesthetical value of the shoe, but it determines a non uniform support of the sole, what results in a consequent discomfort for the user who is even unable to wear said shoes anymore.
- the present invention aims to set aside the disadvantages and drawbacks which are typical of the background art and, thus, to ' provide for a footwear intermediate element which can be easily and cheaply realized, and which can provide for an effective and long lasting coupling of the intermediate element to the sole, thereby assuring a good lateral preservation of the sole edges .
- the footwear intermediate element is provided with a plurality of protuberances which are radially disposed in corrispondence of the edge of the intermediate element and which engage a plurality of conjugated recesses obtained inside of the sole to which said intermediate element is coupled.
- Said protuberances, as well as the corresponding recesses, can vary their number and shape and can be placed along the whole perimetral edge of the intermediate element or along a portion of it, e.g. the portion in proximity of the heel or of the tip of the foot.
- said protuberances are moulded simultaneously with the intermediate element to obtain a single moulded piece.
- the materials which are used to produce the intermediate element, as well as the sole are thermoplastic rubbers, advantageously cured rubbers, PVC, polyurethan and polyolefines, e.g. Adiflex®.
- the intermediate element is advantageously made of materials which are sufficiently soft for assuring a comfortable foot support, though sufficiently rigid in order to assure a firm base for bearing the foot.
- the present invention assures an excellent adhesion of the intermediate element to the sole, thereby avoiding any disadvantageous deflection of the sole, in particular at the edges of the same.
- the coupling of the intermediate element to the sole of a given footwear can be realized by using suitable brackets which provide for the fastening of said intermediate element to the sole.
- brackets are provided with a suitable protuberance which is introduced into a conjugated recess which is worked inside of the sole to obtain the desired coupling mentioned above.
- said intermediate element is fastened by two or more brackets which transversally cross it and which are fastened to the sole portion surrounding the intermediate element .
- the portion of the intermediate element which is crossed by the bracket is suitably shaped to provide for a suitable groove in which the bracket is advantageously located.
- this form of embodiment allows to obtain a satisfactory coupling of the intermediate element to the sole, as well as a correct positioning of the bracket, thereby avoiding an uncomfortable rthickness increase in the area where the user's foot is supported.
- brackets cross only the perimetral portions of the intermediate element and not the whole width of the latter.
- a suitable series of correspondent recesses is provided not only in the sole, but also in the intermediate element which is fastened to said sole along the perimetral edge of the intermediate element itself.
- the intermediate element is provided with a plurality of differently shaped cells and/or chambers which are advantageously distributed on the surface of the intermediate element which directly contacts the sole.
- Said air circulation is particularly advantageous since it allows the foot to be ventilated and avoids, or at least reduces, the foot perspiration, thereby providing a comfort and well-being feeling to the user.
- figure 1 shows a schematic plant view of the coupling intermediate element/sole according to the present invention
- figure 2 shows a schematic section view of an intermediate element according- to a particular form of embodiment of the present invention.
- reference sign 10 indicates a coupling intermediate element/sole according to the present invention.
- Figure 1 shows a particular form of embodiment of the present invention, according to which a footwear intermediate element 11 is provided with a plurality of protuberances 12.
- Saids protuberances 12 are radially disposed in corrispondence of edge 16 of the intermediate element and they engage corresponding recesses 13 machined in sole 14 of a given footwear.
- said protuberances as well as the respective recesses, have an oval shape and are equally distributed along the whole perimetral edge of intermediate element 11.
- the number and shape of said protuberances 12 and recesses 13 can be variable and they can be located in a specific portion of intermediate sole 11 such as, for instance, the tip or the heel portions.
- said protuberances 12 are moulded together with intermediate element 11 by using materials such as thermoplastic rubbers, advantageously cured rubbers, PVC, polyurethan and polyolefins, e.g. Adiflex®, said materials being also used to produce sole 14.
- Protuberances 12 allow a reliable and effective coupling of intermediate element 11 to sole 14 and avoid the escape of the intermediate element from its seat even when the user walks on irregular grounds or makes clumsy movements .
- coupling 10 of intermediate element 11 to sole -14 of a given footwear is advantageously obtained by means of brackets which fasten said intermediate element 11 to the sole from one side to the other.
- brackets are provided with a suitable protuberance engaging a recess 13 of conjugated shape, said recess being machined inside of a sole 14. Consequently, intermediate element 11 is fastened by two or more brackets which transversally cross it, and a suitable groove is provided in the portion of intermediate element 11 which is crossed by said bracket so that an uncomfortable thickness increase can be avoided in the correspondence of user's foot position.
- Figure 2 shows a further form of embodiment of the present invention, according to which intermediate element 11 presents a plurality of cells and/or chambers 15 advantageously distributed on its surface contacting sole 14.
- said cells 15, hemispherically shaped according to figure 2 are deflected and deformed causing the discharge of the air contained therein, said air being advantageously directed towards user's foot.
