Definitions

  • the present invention relates to a waterproof sole with high air and vapor permeability.
  • air permeability and water vapor permeability are two critical aspects that affect the comfortability of shoes.
  • the water vapor and sweat in the shoes can be taken away by the air exchange.
  • the exchange of air, water vapor, and heat between the in-shoe microenvironment and the outside environment has been the subject of quite a few inventions. All the efforts are trying to improve these exchange and therefore to reduce the moist in the microenvironment inside shoes and to improve their comfortbility.
  • US 6,508,015 disclosed a breathable outsole for footwear, in which the outsole has a two-layer structure.
  • the two-layer structure contains an elastic and water vapor-permeable inner layer and an outer layer that covers less than 70% of the inner layer.
  • the breathing activity of outsole is provided by the microporous structure of inner layer and the configuration of outer layer.
  • the configuration of outer layer is such that the surface of inner layer available for water vapor exchange is restricted as little as possible.
  • a microporous structure of insole is achieved, for example, by a sintered plastic.
  • US 6,655,048 disclosed a breathable and waterproof sole for shoes, which comprises, at least along part of its extension, a lower waterproof component, which constitutes the tread; an upper component, with a supporting structure which has chambers which are connected to openings at least on the upper face and the edge; a membrane which is impermeable to water and vapor-permeable and externally surrounds at least the outward-facing regions of the upper component.
  • the lower and upper components and the membrane are joined so as to form a seal at least in the regions where water infiltration is possible.
  • a vapor-permeable and waterproof sole for shoes was disclosed in US 6,681,500 , which comprising: a lower flat element made of shaped rubber-like material, which has a hollow upper region delimited by a border with air passage openings which extend laterally with respect to the ground resting plane; an upper element; a membrane made of waterproof and vapor-permeable material, which is interposed between said lower and upper element at said hollow region; said lower and upper elements and said membrane being joined hermetically in the perimetric regions of mutual contact.
  • US 7,367,141 disclosed a waterproof and breathable sole for shoes, having a structure including a supporting layer which, at least in a preset macroportion, is made of net, felt, or other diffusely perforated material.
  • a membrane made of a material that is impermeable to water and permeable to water vapor is associated above the supporting layer at least in the one preset macroportion made of net, felt or other diffusely perforated material, which it covers.
  • a tread made of plastic material, with at least one through macroperforation at the at least one preset macroportion made of net, felt or other diffusely perforated material, is joined hermetically to the membrane and to the supporting layer at least at the perimeter of the at least one macroportion made of net, felt or other diffusely perforated material.
  • EP 2250917 disclosed a midsole structure that allows easy vapor permeation of the sole and the foot of the user through itself, particularly for shoes, including shoes with a vapor-permeable sole, designed for use in sports activities, comprising a monolithic plantar frame made of polymeric material, which comprises a reinforced rim with structural cross-members, which cooperate to delimit opening compartments that pass through the monolithic plantar frame in order to lead onto opposite faces thereof, at least one first vapor-permeable element, which covers at least the opening compartments, which open onto a first one of the faces, with which the first vapor-permeable element is associated, at least one second vapor-permeable element, which covers at least the opening compartments, which open onto the second one of the faces, with which the second vapor-permeable element is associated.
  • the objective of the present invention is hence to provide a waterproof sole with high air and vapor permeability.
  • the objective of the present invention is also to provide a shoe.
  • a waterproof sole with high air and vapor permeability is disclosed by claim 1.
  • the upper layer and/or the lower layer are made of breathable and waterproof materials with the air permeability of 1.500 kPa ⁇ s ⁇ m -1 to 300.000 kPa ⁇ s ⁇ m -1 .
  • the plurality of channels are perpendicular to the bottom surface of the supporting layer.
  • the plurality of supporting projections are perpendicular to the bottom surface of the supporting layer.
  • the plurality of supporting projections are supporting columns.
  • the plurality of through-holes are inter-connected to each other with the plurality of horizontal channels on the upper side of the outsole layer.
  • the through-holes have their bottom ends at the bottom of outsole layer.
  • a shoe including the above-mentioned sole is also provided.
  • the waterproof sole with high air and vapor permeability has the improved structure which contains a hollow space in the sole, which makes the air and water vapor flow freely inside it, this free flow of air and vapor will facilitate the balance of the heat generated.
  • the another advantage of the new design of the sole is that it can prevent the water pressure building up in the through-holes so as to largely improve the water resistance of the sole. It is well know that the distribution of the pressure of feet is non-uniform. [1] When the sole is in contact with water, due to the pressure distribution, certain parts of the sole will have much higher pressure building up, such as those under metatarsals and heel, while other parts such as under the mid-foot would have much less pressure. Once the water pressure increases in the through-holes of the high pressure parts of the sole, water can be directed by the inter-connecting channels to the parts where the pressure is low and the water may even flow out of the outsole through the through-holes in those parts. As a result, the water pressure will not be built up. This way, the water resistance property of the sole can be significantly improved, even with the use of materials such as fluorochemicals surface treated textile fabrics.
  • the design of the sole currently described has the advantage of high air and vapor permeability and facilitate the heat exchange with outside environment. With such sole design, the comforability of the shoe made with the sole would be largely improved. In addition, the design of the sole also prevents the water pressure build-up so that a wide variety of water resistant and water-repellent materials can be used.
  • Fig. 1 is the cross-section view of the waterproof sole with high air and vapor permeability according to the present invention
  • Fig. 2 is the exploding perspective view of the waterproof sole with high air and vapor permeability according to the present invention
  • Fig. 3 is the bottom perspective view of the supporting layer
  • Fig. 4 is the top perspective view of the outsole layer
  • Fig. 5 is the top perspective view of the through-holes and the horizontal channel in the outsole layer.
  • a waterproof sole with high air and vapor permeability 10 is depicted, which contains an upper layer 11, an lower layer 15, a shaped supporting layer 12 located between the upper layer 11 and the lower layer 15 and a outsole layer 16 below the lower layer 15.
  • the upper layer 11 and/or lower layer 15 are made of breathable and waterproof material, for example, cotton fabrics or the polyester fabrics treated with low surface energy materials, such as fluorochemicals, silicone materials, wax, or any other materials with low surface energy and hydrophobic properties.
  • the breathable and waterproof materials have the air permeability of 1.500 kPa ⁇ s ⁇ m -1 to 300.000 kPa ⁇ s ⁇ m -1 , much lower than the of waterproof materials used in prior art, so as to largely reduce the heat and water vapor building up in the shoe and hence improve the comfortability.
  • the shaped supporting layer 12 has a plurality of channels 13 therein, which connect the bottom surface to the top surface of the supporting layer 12 and hence connect the upper layer 11 and the hollow region 19 formed when the supporting layer 12 and the outsole layer 16 are integrated. Furthermore, the shaped supporting layer 12 also has a plurality of supporting projections 14, which are present in the hollow region 19 formed when the sole is integrated.
  • the channels 13 and the supporting projections 14 are both perpendicular to the bottom surface of the supporting layer 12, and are therefore substantially perpendicular to all the top and/or surface(s) of the upper layer 11, the lower layer 15, the supporting layer 12 and the outsole layer 16 at least in the certain small areas. More preferably, the supporting projections 14 are supporting columns that are perpendicular to the bottom surface of the supporting layer 12.
  • the outsole layer 16 is below the lower layer 15, and has a plurality of through-holes 17 therein. And the plurality of through-holes 17 are connected to each other with the plurality of horizontal channels 18 (see Fig. 4 and Fig. 5 ). Preferably, the bottom ends of the through-holes 17 are at the bottom of outsole layer (see Fig. 5 ).
  • the supporting layer 12 and/or the outsole layer 16 are made of, for example, rubber-like material.
  • the improved structure of the sole with high air and vapor permeability enhances the air exchange between the in-shoe microenvironment and the outside environment.
  • the high air and vapor permeability through the sole is enabled, and therefore the in-shoe dry microenvironment can be kept and the odours are prevented to be produced.
  • the above-mentioned soles can be used in various kinds of shoes and improve the comfortability while people wearing the shoes.
