Definitions

  • the present invention relates to a transpiring sole for shoe.
  • the present invention relates to a shoe's sole of the transpiring and waterproof type.
  • transpiring soles of the known type usually comprise transpiring waterproof membranes of the micro-porous type, for example of the type known on the market as Goretex®.
  • transpiring soles of the known type comprise osmotic membranes which, as said, prevent the entrance of water from the outside and selectively allow the escape of humidity from inside the shoe.
  • Such amount of humidity that may be ejected by the membranes is certainly not sufficient, for example, in usage conditions where the foot sweats more than usual. Just to mention a few situations, let's think of especially hot and sultry days or of the use of the shoe for sports activities, also in a hot and humid weather.
  • the technical task of the present invention therefore is to obviate the above drawbacks by providing a transpiring shoe's sole characterised by a higher transpiring capacity than the shoes of the known type, besides an optimal impermeableness to the water coming from the outside.
  • an object of the present invention is to make a transpiring sole for shoe which allows obtaining a better air circulation inside the same shoe.
  • the transpiring sole in fact comprises a first element, in direct contact with the ground, provided with holes, a second element overlapped to the first element and provided with at least one seat for a transpiring insert that is self-sealing in contact with humidity, a seat that is provided at said holes.
  • the sole further comprises a third element, overlapped to the second element, provided with openings provided at the seat, and a fourth transpiring element placed in direct contact with the foot sole.
  • the above holes, insert and openings define a passage channel for air and humidity, which allows eliminating higher amounts of humidity from inside the shoe than shoes with soles of the known type.
  • the self-sealing insert allows completely closing said passage channel in the presence of water or high humidity on the outside, preventing the penetration thereof into the shoe.
  • reference numeral 1 globally denotes a transpiring sole for shoe according to the present invention.
  • the transpiring sole according to the present invention may be applied to any type of shoe, with no limitations.
  • the sole may be applied to elegant, sports, free time and yet other types of shoes.
  • the sole may be used for shoes wherein for the user it is necessary to obtain a particular sensation of comfort from the point of view of transpiration along with features of total waterproofing in the use in rain, cold, bad weather and similar conditions, as it shall appear more clearly from the following detailed description.
  • sole 1 is inserted in a shoe, globally indicated with reference numeral 2, schematically shown only for the purpose of a better understanding of the invention.
  • Sole 1 as is seen in particular in figure 1 and in figure 2 as well, comprises a first element 3, which in use is in direct contact with the ground.
  • Sole 1 further comprises a second element 4, directly overlapped to the first element 3.
  • the second element 4 is provided with at least one seat 5 for a transpiring insert 6 that is self-sealing in contact with humidity, with the advantages that shall appear more clearly in the following description.
  • Sole 1 further comprises a third element 7, directly overlapped to the second element 4.
  • Sole 1 finally comprises a fourth transpiring element 8 which in use conditions is in direct contact with the foot sole.
  • the first element 3 of sole 1 is substantially extended to all or to parts of the foot sole and carries out the function of adhesion to prevent dangerous slipping.
  • the first element 3 is made, for example, of a natural or synthetic rubber, cured or thermoplastic, or also of another elastomeric material (such as TPU, PU, etc.) provided with suitable mechanical features for withstanding direct contact with the sole during the usage steps (walking, running, etc.).
  • the first element 3 of sole 1 comprises holes 9 for air passage, for example circular or of another shape.
  • holes 9 for air passage are in particular grouped and concentrated at the front zone of the foot sole, substantially at the centre of said front zone.
  • Such holes may have very different shapes, number and dimensions according to the shoe model and to the shape and dimensions of the transpiring and self-sealing insert 6.
  • holes 9 for air passage may also be provided in other zones of the foot sole.
  • the second element 4 is made of a foamed elastomeric material such as EVA, PU, natural and synthetic rubber or other polymeric material, or of another nature, with suitable features, selected among those commonly used in the field, for example among those elastically flexible, with a limited weight, and with other advantageous features in the production of shoe soles.
  • the second element 4 of sole 1 is fixed to the first element 3 by gluing, or by other equivalent fixing means.
  • the second element 4 preferably has a larger thickness than that of the first element 3, and in any case a suitable thickness for seating insert 6 in an optimal manner.
  • the second element 4 is only extended to a portion of the foot sole, that is, the front portion. In fact, the second element 4 is delimited by a cross edge substantially placed at the central portion of the foot sole.
  • Seat 5 for the above self-sealing transpiring insert 6, as is seen in figure 2 is substantially provided at holes 9 for air passage; in other words, seat 5 is partly or completely overlapped to holes 9 in usage conditions of shoe 2, so that certain air circulation may take place thereinbetween while walking.
  • the second element 4 may also be provided in other zones of the foot sole, in relation to the specific application requirements and to the desired results.
  • the self-sealing transpiring insert 6, schematically shown in figure 3 comprises at least one absorbing layer 10 for humidity and water, comprised between two air-permeable layers 11, 12, which may be identical to each other or also different: for example, materials with a different air permeability, with a different resistance, may be used for making such two air-permeable layers 11, 12.
  • the absorbing layer 10 may be made, for example, of a polymeric material having suitable properties; in particular, the so-called super-absorbing polymeric materials may be used.
  • the absorbing polymeric material may be mixed for forming the absorbing layer 10, with a filler material of the known type.
  • the materials for making the absorbing layer 10 and those for making the air-permeable layers 11, 12 in any case are of the known type. They are based on the technology developed by IQ TEX ® in collaboration with BASF ®. Such technology allows making highly transpiring/waterproof inserts by the use of super-absorbing materials produced by BASF ®.
  • the above three layers 10,11,12 of insert 6 are assembled so that in dry conditions, there is a certain distance between them, defined based on the design specifications, that is, based on the functional features that are to be imparted to the same insert 6.
  • Insert 6 may further be provided with other outside protective layers, on one or both sides, made of materials of known use in the field.
  • Insert 6 may also be provided with a stiff support inserted in seat 5.
  • the third element 7 of sole 1 is overlapped to the second element 4, and is connected to the latter for example through gluing, or by other equivalent connecting means of a known use in the field.
  • the third element 7 of sole 1 extends by a surface substantially equal to that of the shoe plan, and has a thickness for example larger than that of the second element 4, although it may also have a smaller thickness, in relation to the specific requirements.
  • the third element 7 of sole 1 is made for example of a foamed elastomeric material such as EVA, PU, or natural or synthetic rubber, or other polymeric material, or of another nature, with suitable features, selected among those commonly used in the field, for example among those elastically flexible, with a limited weight, and with other advantageous features in the production of shoe soles.
  • a foamed elastomeric material such as EVA, PU, or natural or synthetic rubber, or other polymeric material, or of another nature, with suitable features, selected among those commonly used in the field, for example among those elastically flexible, with a limited weight, and with other advantageous features in the production of shoe soles.
  • the third element 7 comprises openings 13 for air passage, for example circular or of another shape. More in detail, openings 13 for air passage of the third element 7 are grouped at the front zone of the foot sole, substantially at the centre of said front zone. As is seen in particular in figure 2 , openings 13 of the third element 7 are positioned so as to be at seat 5 of the second element 4, that is, partly or completely overlapped thereto, and therefore at insert 6.
  • an air passage channel is created between the shoe interior and the outside environment, said channel being globally indicated with reference numeral 14 in figure 1 : such channel 14 is defined, in the outside-inside direction, by holes 9 of the first element 3, by insert 6 and by openings 13 of the third element 7.
  • the fourth transpiring element 8 of sole 1 extends by a surface substantially equal to that of the shoe 2 plan, as shown in figures 1, 2 .
  • the fourth element 8 may be fixed on top of the third element 7 by gluing or other equivalent connecting means, or it may be simply seated into the shoe, as insole.
  • the fourth element 8 is intended to be in direct contact with the user's foot sole or in any case with the sock worn by the user, and therefore it may be necessary to make it simply and quickly interchangeable mainly for hygiene reasons.
  • the fourth element 8 is made of fabric or three-dimensional mesh, of a per se known type.
  • the material such fabric or three-dimensional mesh is made of is, for example, polymeric material such as PP (polypropylene), PVDC (polyvinyldene chloride), PES (polyester).
  • a mixed PVDC/PES material may also be used for having good thermo-weldability at the edges along with sufficient load-bearing capacity.
  • Such paths 15 are, for example, parallel to each other and longitudinal relative to the front-back axis of sole 1, and they are open at the respective ends.
  • the fourth element 8 allows air circulation inside shoe 2 and underneath the foot sole; moreover, the air circulation paths 15 of the fourth element 8 directly communicate with openings 13 of the third element 8, and thus with insert 6 and therefore, through holes 9 of the first element 3, with the outside environment.
  • sole 1 The usage way and the operation of sole 1 according to the invention are described hereinafter.
  • the passage channel 14 defined by holes 9, by insert 6 and by openings 13, along with the fourth element 8 allows the high and optimal foot transpiration inside shoe 2: in other words, the humidity generated by the foot inside shoe 2 easily escapes through holes 9 thanks to the high air circulation inside the same shoe, strongly favoured by the presence of the fourth element 8.
  • insert 6 allows the free air passage through its thickness thanks to the outside permeable layers 11,12, so as to perform the function of foot transpiration. In this way the user of the shoe provided with sole 1 feels a strong sensation of comfort.
  • the two air-permeable layers 11,12 in fact, have a transpiring and protective function, and moreover they cooperate for closing the insert in the presence of humidity and/or water coming from the outside.
  • the absorbing layer 10 of insert 6 undergoes a progressive increase in volume, proportional to the amount of water absorbed, until its surface adheres to the surface of at least one of the two outside air-permeable layers 11,12, or at least of the innermost one 11 relative to shoe 2: in this way, the passage of both air and water through insert 6 is prevented, so that the user may feel a dry sensation also in the presence of water outside.
  • the absorbing layer 10 progressively disperses the previously absorbed humidity outwards, through the permeable layer 12, and decreases in volume, so as to restore the normal conditions of foot transpiration and free air passage in a short time.
  • sole 1 for shoe according to the present invention allows obtaining important technical advantages.
  • sole 1 In the first place, the transpiring capacity of sole 1 is significantly increased compared to what happens in the transpiring soles of the type currently widespread on the market. In fact in sole 1 according to the present invention, the transpiring or micro-porous membranes that characterise other known shoes and that, as said, do not exhibit satisfactory performance from the point of view of transpiration, are not provided.
  • the increase of the transpiring capacity of sole 1 itself is further increased, in a decisive manner, by the presence of the fourth transpiring element 8.
  • the latter in fact, greatly favours the air circulation underneath the foot sole, and thus it allows eliminating also the humidity coming from zones of the sole that are away from channel 14, that is, in the present embodiment, from the zones for example of the heel.
  • Sole 1 according to the present invention besides the increased capacity of transpiration compared to the known soles, is characterised, as said, also by the perfect seal in the presence of a humid or wet outside weather.
  • FIG 4 Another embodiment of the sole according to the invention is shown in figure 4 .
  • parts corresponding to those of the previous embodiment are indicated with the same reference numerals, increased by 100 units.
  • the second element 104 is substantially extended to the entire foot sole.
  • Seat 105 for insert 106 is still provided at the front zone of the foot sole, as in the previous embodiment.
  • this solution may be used if a second element 104 is desired to be provided between the first element 103 and the third element 107 in the heel zone as well, the second element 104 being made, for example, of a material with the desired mechanical features - for example a shock-absorbing material for the foot impact on the ground - active on the entire foot sole, and thus not only in the front zone.
  • the second element 204 is provided with two seats 205 for two respective inserts 206, of which one in the front zone and one in the back zone.
  • the first element 203 is provided with two distributions of holes 209, of which one in the front zone and one in the back zone.
  • the third element 207 comprises two distributions of openings 213, of which one in the front zone and one in the back zone.
  • the fourth element 208 is the same as the previous embodiments.
  • the second element 204 may comprise a plurality of seats 205 provided in different zones of the foot sole - selected by number and position in relation to specific usage requirements - a corresponding plurality of distributions of holes 209 in the first element 203 and a corresponding plurality of distributions of openings 213 in the third element 207.
  • FIG. 6 Yet another embodiment of the sole according to the invention is shown in figure 6 .
  • the second element 304 of sole 301 comprises a single seat 305 for a single insert 306 that extends from the front zone to the back zone of the foot sole.
  • the first element 303 comprises a distribution of air passage holes 309 that extends from the front zone to the back zone of the foot sole.
  • the third element 307 of sole 301 comprises a distribution of openings 313 that extends from the front zone to the back zone of the foot sole.
  • the fourth element 308 is the same as the previous embodiments.
  • a single air passage channel 314 is therefore defined, larger than in the previous embodiments, the section whereof extends from the front zone to the back zone of the foot sole.
  • FIG. 7 Another embodiment of the sole according to the invention is shown in figures 7 , 8 .
  • sole 401 is coupled to the vamp of a shoe 402 of any kind.
  • sole 401 comprises a first element 403, a second element 404, a third element 407 and a fourth element 408.
  • the second element 404 comprises a seat 405 for a transpiring insert 406 whereat, as already described for the previous embodiments, an air passage channel 414 is defined.
  • This embodiment is characterised by the particular shape of the fourth element 408, shown in figure 8 .
  • Such fourth element 408, in fact, besides defining paths 415 for air circulation, comprises lowered zones 416, of various shapes and geometries, that define thin and flexible portions of the fourth element 408 - those having the lowered zones 416 - alternating with portions with a transpiring and shock-absorbing capacity, those where paths 415 are.
  • Such lowered zones may consist, as in the example of figure 8 , of longitudinal, cross strips or closed lines, like the external one or that of the heel zone.
  • the result is a third element 408 with a different behaviour according to the different portions of the foot sole.
  • elements 403, 404, 407 and insert 406 may be of the type described in any one of the previous embodiments.
