    Description

    [0023] Further characteristics and advantages of the elements of an assembled footwear with pre-formed parts, according to the present invention, will be more clear from the following description, with reference to preferred embodiments, and from the enclosed drawings, in which:

    [0024] FIG. 1 shows in exploded view a footwear made with the elements of the invention, according to a first embodiment of the invention;

    [0025] FIG. 2 shows the footwear of FIG. 1;

    [0026] FIG. 3 shows a first part of an element of the invention, according to a second embodiment of the invention;

    [0027] FIG. 4 shows a second part of an element of the invention, according to the second embodiment of the invention;

    [0028] FIG. 5 shows a front view of the element of the invention, according to the second embodiment of the invention, in which the first part of FIG. 3, the second part of FIG. 4 and a third part are shown;

    [0029] FIG. 6 shows a first side view of the element of FIG. 5;

    [0030] FIG. 7 shows a second side view of the element of FIG. 5;

    [0031] FIG. 8 shows a bottom view of the element of FIG. 5;

    [0032] FIG. 9 shows a cross-section view of the element of FIG. 5 in a rest position;

    [0033] FIG. 10 shows a cross-section view of the element of FIG. 5 in a rest position;

    [0034] FIG. 11 shows a top view of the element of FIG. 5.

    [0035] With reference to the above mentioned figures, the invention comprises the following aspects, starting from the creation of a product consisting of a supporting or bearing frame 10 (FIG. 1), 20 (FIGS. 3-11) wrapped by the thermoformed components or parts 1, 2, 3, 4, 5, 6, 7 (FIGS. 1-2), 21, 22 (FIGS. 3-11) which constitute the upper or the sole 30.

    [0036] In particular, thanks to the use of a supporting frame, for example a shaped reticular structure 10, 20 formed ergonomically around a suitable shaping definable from time to time, such as the foot of a user scanned by a 3D scanner and reproduced exactly for a footwear tailored with modern technologies or such as the forms of a standard foot employed to simulate the different sizes, it is possible to apply functionalizing elements, such as a lining and/or a waterproof membrane (not shown) by means of sewing or gluing at the top or at the bottom of the bearing frame 10, 20.

    [0037] In detail, for example, said reticular structure 10, which is technically called with the name of sock, can be constituted by synthetic textile semi-flexible, semi-rigid, plastic or thermoplastic elements, or by a suitable synthetic structure made by molding or similar techniques (such as 3D printing), suitable to wrap around the foot.

    [0038] The application of functional elements, such as lining or multifunctional membranes (waterproof, breathable, thermo-insulating, antibacterial membranes), can take place by gluing or sewing said membranes in the upper part or in the lower part of the frame.

    [0039] With reference to FIGS. 1 and 2, each element of the upper, such as the sole 1, the midsole 2, the left flank 3, the right side 4, the upper part or tab 5, the ferrule 6 and the heel 7, can be made of leather or other textile, synthetic, artificial or natural materials, which are coupled to the surface of the reticular structure 10 facing towards the outside, by means of suitable adhesives and/or supports made of microfiber, such as non-woven fabrics or fake leather, suitable to give a great support to the element constituting the upper.

    [0040] With reference to FIGS. 3-11, also the combination between the components of the midsole and/or of the sole can be made by gluing, stitching or coupling techniques and taking advantage of the adhesives crystallization method known as HOT/COLD, through the use of specific thermo-adhesive glues.

    [0041] According to a preferred embodiment of the invention, which is shown in figures from 3 to 11, the shaped reticular structure 20 is made of a material with high wear resistance, high abrasion resistance, high tensile and tear strength, good damping capacity and good flexibility at low temperatures, as well as high resistance to oils, greases, oxygen and ozone.

    [0042] For example, said material could be a thermoplastic polyurethane (TPU). Said reticular structure 20 can be coupled to a lower protection element 21 made of rubber and to a higher ergonomic element 22 made of a softer material, for example ethylene vinyl acetate (EVA).

    [0043] Preferably, the reticular structure 20 has a series of holes 23 and reinforcement lines 24.

    [0044] Equally preferably, the lower protection element 21 made of rubber has protruding elements 25, facing towards the opposite direction with respect to the reticular structure 20, and/or holes 26.

    [0045] According to a preferred embodiment of the invention, the protruding elements 25 of the lower protection element 21 are positioned in correspondence of the holes 23 of the reticular structure 20, and/or the holes 26 of the lower protection element 21 are positioned in correspondence of the reinforcing lines 24.

    [0046] In this way, advantageously, the protruding elements 25 are able to adapt the sole to the irregularities of the ground, keeping the comfort for the user.

    [0047] The particular combination of the reticular structure 20, the bottom protection element 21 made of rubber and the upper ergonomic element 22 allows that each protruding element 25 could go back independently of the other adjacent elements, only with the resistance of the upper ergonomic element 22, which is made of a soft material so as to oppose little resistance and allow a slight movement of said elements.

    [0048] As can be seen from FIGS. 9 and 10, preferably, the ergonomic element 22 is configured so as to adapt to the shaping of the reticular structure 20 and to fill all said holes 23. In other words, the cross-section views of FIGS. 9 and 10 show how the ergonomic element 22 has a complementary shape with respect to the shape of the reticular structure 20, which is equipped with protruding elements corresponding to the holes of said reticular structure 20.

    [0049] In detail, the individual pre-formed components or parts 1, 2, 3, 4, 5, 6, 7, 21, 22 can be applied to the reticular structure 10, 20 by gluing, sewing or coupling techniques exploiting the adhesives crystallization method known as HOT/COLD, or through the use of specific thermo-adhesive glues. Thanks to the winding of the pre-formed components 1, 2, 3, 4, 5, 6, 7, 21, 22 around the reticular structure 10, 20 and thanks to the whole assembly among said pre-formed components, it is possible to obtain the footwear 30 assembled from pre-formed parts as shown in FIG. 2.

    [0050] Furthermore, by means of a thermoforming process and thanks to the adoption of specific male-female molds at certain pressure and temperature values, a desired pre-bending (or pre-forming) of the single parts 1, 2, 3, 4, 5, 6, 7 is obtained.

    [0051] Finally, the invention thus conceived is susceptible to numerous modifications and variants, all falling within the inventive idea of the attached claims; moreover, all the details may be replaced with other elements which are technically equivalent.

    [0052] In particular, the footwear thus obtained can have a different number of layers, ensuring the same way said desired features of comfort.

    [0053] Finally, the materials employed, as well as the dimensions may be any according to requirements and the state of the art.

    [0054] Where the features and techniques mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly said reference signs do not have any limiting effect on the interpretation of each element identified by way of example by said reference signs.
