摘要:
An assembly insole impermeable to water and permeable to water vapor, with a structure including a membrane impermeable to water and permeable to water vapor and arranged in an upward region, and a supporting layer arranged below the membrane, made of a material resistant to hydrolysis and vapor-permeable or diffusely perforated, and capable of acting as a support for the foot, as a manufacturing base for the shoe, as an element for protecting the membrane against the penetration of blunt objects, and of withstanding the stresses induced in the shoe during use. The membrane and the supporting layer are mutually joined so as to make, as a whole, the assembly insole impermeable to the passage of water and not compromise the vapor permeability of the membrane.
摘要:
A waterproof and breathable sole for shoes, including a lower layer, including at least one large through hole. Above the lower layer, a mesh is provided, arranged to overlap at least the large through hole. A membrane made of a material that is impermeable to water and permeable to water vapor is associated in an upward region with respect to the mesh at least at the large hole. The membrane is joined hermetically at least perimetrically to at least one component of the sole so as to avoid liquid rise through the perimeter of the large hole. A perforated upper layer is arranged above the membrane. The lower layer is overmolded on the mesh and partially incorporates the mesh.
摘要:
A vapor-permeable and waterproof sole for shoes, including at least one first load-bearing component, including at least one vapor-permeable or perforated portion, including a vapor-permeable or perforated filler, at least one second component, predominantly arranged below the first component with a tread provided thereon. The second component includes through perforations at the vapor-permeable or perforated portion of the first component. Below the vapor-permeable or perforated portion and above the tread a membrane water impermeable and of water vapor permeable material is provided. The first component is constituted by a plastic midsole. The midsole is rigidly coupled to the membrane and to the filler by molding before providing the tread. A single peripheral seal is provided on the membrane formed by the molding of the midsole; the midsole surrounds peripherally the membrane.
摘要:
A waterproof and water vapor-permeable shoe, including a bottom shoe part with a sole perforated through from the tread toward a foot resting region, a top part surrounding the foot and including a vapor-permeable or perforated lining, a waterproof and vapor-permeable membrane surrounding the foot, and a vapor-permeable or perforated upper. The outer bottom portion of the top shoe part, which is superimposed on the perforated area of the sole, is constituted by a portion of the membrane. A vapor-permeable or perforated protective element for the portion of the membrane is provided below the portion of the membrane and above the tread of the sole. A water sealing region provided between the portion of the membrane and the sole, around the perforated area of the sole, separates flaps of the upper from the perforated area of the sole.
摘要:
An insert for vapor-permeable and waterproof soles, which has a stratified and cohesive monolithic sheet-like structure, which includes a plurality of functional layers made of a polymeric material that is impermeable to water in the liquid state and permeable to water vapor. At least one functional portion of the insert for soles has such a thickness as to give it a penetration resistance of more than approximately 10 N, assessed according to the method presented in chapter 5.8.2 of the ISO 20344-2004 standard.
摘要:
An insert for soles, particularly for perforated soles made of polymeric material, comprising a membrane that is impermeable to water and permeable to water vapor, the insert comprising a supporting layer made of mesh, felt or other diffusely perforated material, a vapor permeation component, which comprises the membrane arranged above the supporting layer, a layer of polymeric material that impregnates locally the supporting layer, so as to form therein a matrix for the adhesive bonding thereof to other components of the shoe, a region for sealing the supporting layer to the vapor permeation component. The adhesive bonding matrix affects at least the perimetric region of the supporting layer and delimits at least one vapor-permeable portion of the supporting layer, which is free from polymeric material. The sealing region provides for the intimate grip of the polymeric material, which impregnates the supporting layer, to the membrane.
摘要:
A waterproofed and breathable sole for shoes, which comprises a tread made of leather, or similar breathable and water-permeable material, which is at least partially covered in an upward region by a membrane made of a material that is breathable and impermeable to water and is perimetrically joined to the tread with the interposition of a sealant or by direct adhesion thereof so as to provide a seal.
摘要:
A breathable shoe, including: an upper assembly (10;310;410) having a breathable upper (11;311;411); a membrane (14;314;414) made of a material which is waterproof and breathable, and a sole (16;116;216;316;416) made of perforated elastomer, which are all mutually attached such that the membrane is arranged between the upper assembly and the sole, and the sole is sealed perimetrically to the membrane, in a manner to prevent moisture to enter into the upper assembly from the sole through the membrane, and to permit moisture to leave the inside of the upper assembly through the membrane and through the sole. In one preferred embodiment, the membrane is first attached to the upper assembly so that the upper assembly is a unitary upper assembly including the membrane, and such unitary upper assembly is subsequently attached to the sole.
