Definitions

  • the invention relates to footwear with a shaft which has a lining layer on the inside of an outer layer, a waterproof, water-vapor-permeable functional layer being arranged on the outside of the lining layer, and a method for producing waterproof footwear.
  • waterproof shoes with a breathable membrane can be produced by arranging a microporous or homogeneous plastic membrane as a functional layer on the inside of the outer layer of the shaft, which is impermeable to water but permeable to perspiration moisture caused by foot perspiration .
  • This water-impermeable, but water-vapor-permeable functional layer allows the foot or sweat moisture to be removed from the inside of the shoe, but in order not to impair the intended waterproofness or density, the membrane must not be connected to the outer shaft material in a conventional manner by sewing, because the Seams give the water access to the inside of the shoe.
  • footwear has already been proposed by G 90 04 403.7, which has a spacing element provided between the circumferential edge of the lining and that of the shaft, which is a first sweatband made of polyurethane attached to the circumferential edge portion of the lining, the edge of the Lining with which the shaft can be connected by means of a connecting seam.
  • the sweatband forming the spacer element is welded to the lining or the microporous functional layer of the lining.
  • the lining is then sewn onto the circumferential edge of the shaft and the insole is also sewn onto the circumferential edge of the intermediate product thus produced.
  • This is followed by the injection molding of the waterproof plastic sole, which can preferably consist of polyurethane.
  • the molded plastic sole seals the interface between the functional layer and the upper and, if necessary, the insole against the direct impact of water or splash water.
  • the shaft materials such as leather or textile or textile-like fabrics made of cotton or plastic fibers have the property that they conduct water in the longitudinal direction, which also applies to shaft materials made of leather or textile fabrics.
  • a footwear in DE-OS 38 21 602 a footwear is disclosed, the upper of which consists of a lining, a waterproof, water vapor-permeable microporous functional layer and a waterproof plastic sole molded onto the lower region of the upper.
  • the footwear is characterized in that at least the lower shaft area located in the outsole area is covered by a porous material, e.g. Spacer, is to be formed, which can be penetrated by the liquid plastic sole material during injection.
  • the liquid material of the plastic sole can reach the functional layer or the laminate making up the functional layer when it is injected onto the upper and, if appropriate, onto the insole through the lower upper. This is intended to ensure that the molded plastic sole material seals the seam holes of the connecting seam between the insole, functional layer and upper.
  • the spacer enables the liquid plastic sole material to penetrate into the pores of the spacer, it does not improve the creep of water in the shaft material Achievable due to the water capillary forces, because the high mechanical loads on the footwear when rolling off can in the long run lead to tearing of the pore wall or at least tearing of the glued synthetic sole material from the pore of the spacer, thereby stressing the connections between the plastic sole material and the still intact Spacer is only enlarged.
  • the water that has penetrated into the lower region due to the longitudinal conduction effects of the shaft material can creep quickly and in large quantities and between the spacer and the functional layer on the bottom - reinforced by capillary forces - and through the gap area between the functional layer and the outer edge of the insole into the inside of the shoe.
  • the conventional shoe requires a very high shell height because of the large number of pores in the upper material, so that, understandably, the flexibility of the shoe is severely restricted and the rolling movement is also made more difficult.
  • an additional consumption of plastic sole material is necessary because of the additionally required shell height, quite apart from the fact that the increased shell height severely limits the aesthetic design of the footwear, and thus also makes the use of the porous shaft material impossible, at least in fashion and street shoes.
  • the lower region of the upper is oriented essentially perpendicular to the underside of the outsole, so that the edge of the lower upper region is at the level of the insole surface.
  • This embodiment may delay the penetration of water because of the shaft reaching to the insole, but since the lower end region of the shaft material has pores, there is a latent risk that insufficient plastic sole material will pass through the pores of the shaft material to the spacer during the molding arrives, so that this creates water-conductive gaps.
  • the shaft material can also consist of tissue at which there is a risk that when punching the pores in the lower end region of the shaft fibers of the textile or leather fabric are pressed into the pores, which can thus act as ideal water bridges.
  • the threads introduced into the pores also lead to a lack of adhesion between the penetrating liquid plastic sole material and the pore inner wall of the shaft material or the spacer, as a result of which the purpose intended according to the state of the art, namely an increased adhesion between the shaft material and the thin-flowing outsole material, on the contrary is reversed.
  • the result is the penetration of water into the area between the lower end area of the upper material and the spacer, which causes at least a wetting of the connection zone between the insole area and the lower upper area.
  • the water creeping through the shaft material penetrates to the spacer, wets this area, migrates through the spacer to the guide loop arranged on the inside of the spacer due to the cracks and gaps described above, and finally arrives via the guide loop as an ideal water bridge through the water-permeable insole inside the shoe.
  • the object of the invention is to remedy this and to eliminate the disadvantages of the prior art.
  • this should not only prevent water from getting into the inside of the shoe through the upper material, but also make it possible for the aesthetic design of the footwear not to be restricted by technical constraints or requirements such as large shell heights.
  • a functional layer such as a homogeneous functional layer, i.e. excellent, permanent absolute waterproofness, windproofness and breathability, combined with sufficient flexibility when rolling the user's foot.
  • the invention thus relates to footwear with a shaft which has a lining layer on the inside of an outer layer, a waterproof, water-vapor-permeable functional layer being arranged on the outside of the lining layer, which is characterized in that an insole or a ball layer is parallel on a Intermediate layer rests, the intermediate layer is adhesively bonded to the insole or ball-out layer by means of an adhesive and / or heat, preferably under the action of pressure, and the lower end regions of the functional layer and the lining layer are folded over and aligned essentially parallel to the upper side of the intermediate layer.
  • Another object of the invention relates to a method for water-impermeable sealing of the connection zone between the insole area and the lower shaft area of a footwear with a shaft which has a lining layer on the inside of an outer layer, a waterproof, water vapor-permeable functional layer on the outside of the lining layer is arranged, which is characterized in that an insole or a ball layer is placed in parallel on an intermediate layer, the intermediate layer is glued to the insole or ball layer waterproof with an adhesive and / or heat, preferably under pressure, and the lower end regions of the functional layer and the lining layer are turned over and aligned substantially parallel to the top of the intermediate layer.
  • the folded-over lower end region of the functional layer 4 is glued watertight by means of an adhesive with a, preferably watertight, intermediate layer 5, it is ensured that there is a large bonding zone between the intermediate layer 5 and the functional layer 4.
  • This large bond zone effectively prevents detachment of the intermediate layer from the functional layer in spite of the heavy load on the footwear during the rolling movement of the user's foot.
  • water which creeps into the lower region of the upper due to the longitudinal guide paths in the upper material, cannot migrate into the interior of the shoe due to the intermediate layer acting as a water barrier.
  • the structure of the footwear according to the invention ensures excellent flexibility since, in contrast to the prior art, a large shell height of the plastic sole is no longer required.
  • the shell height of the plastic or leather sole there are no limits to the design possibilities of the shoe with the structure according to the invention, because now no considerations or constraints.
  • the shell height of the plastic or leather sole This means that the area of application of the footwear according to the invention is also expanded to include street and straight fashion shoes, and there are no limits to the use of this footwear.
  • the insole or ball-out layer 6 can be glued to the intermediate layer 5, the gluing over the entire area guarantees an increase in the statics when the foot is relieved and relieved of pressure by the user's foot.
  • the intermediate layer 5 can be used as a coating compound on the insole or the ball layer 6 and on the lower folded-over end region of the functional layer 4, preferably under pressure and / or Exposure to heat, applied or by means of an adhesive and / or heat, preferably under pressure, with the insole or the ball-out layer 6 and the lower folded-over end regions of the functional layer 4 to be glued watertight.

  • the inside of the shoe is not only hermetically sealed by the presence of a functional layer 4 and an intermediate layer 5, but also sealed by the bonding of large-area connection zones both of the functional layer 4 with the intermediate layer 5 and of the insole 6 with the intermediate layer 5.
  • the structure of the footwear according to the invention combines the excellent properties, for. B. the homogeneous functional layer made of a hydrophilic polyester, such as absolute water and wind tightness and extreme breathability, with the advantages of footwear in terms of excellent flexibility and successful rolling properties.
