Definitions

  • the invention relates to footwear, which is at least part of a shoe, consisting of a shaft, which has at least one outer layer and a lining lining the outer layer of the inside, containing a waterproof and water vapor-permeable layer, one with the lower one End region of the insole connected to the outer layer and a sole.
  • Shoes whose footwear contains a lining containing a waterproof and water vapor-permeable functional layer are widely known for their comfort. But it is always a problem to ensure that such shoes are watertight, because, for example, any seam that is attached to the lining layer can transport water inwards due to capillary forces.
  • the lining containing the waterproof, water-vapor-permeable functional layer is often designed in the form of a sock (known under the name Booty), which is only on the upper opening of the Shoe is connected to the outer layer.
  • Booty sock
  • the seams or other types of connection required to form the sock can be easily sealed with a waterproof adhesive tape, so that the sock design of the lining guarantees watertightness.
  • lining In the case of the sock design, however, lining must also be present in the area of the sole in order to make the interior area hermetically watertight, although in the sole area the water vapor permeability of the lining is often of no importance because the material of the sole does not allow water vapor to pass through. In this respect, the formation of the lining layer as socks (booty) is too complex for many applications.
  • a porous strip was used for shoes with a molded-on sole to connect the outer layer and the lining, through which the sole material penetrates through the porous strip onto the lining during injection, so that the seam connecting the porous strip to the lining is surrounded by the sole material.
  • This embodiment cannot be applied to shoes of the flex type, for example.
  • the lower region of the outer layer is turned outwards in such a way that this lower end region of the outer layer is arranged at least approximately parallel to the outsole and sewn to the insole, the end edge of the folded end region of the outer layer and the End edge of the insole have the same contour. In order to ensure watertightness, these types of shoes are still executed in a complex construction with socks.
  • the object of the present invention is to design footwear of the type mentioned at the outset in such a way that their production is less complex, at least in the Areas in which water vapor permeability is not required, use as little as possible of the complex lining containing a waterproof and water vapor permeable layer.
  • the footwear should be suitable for the production of shoes in a flexible construction.
  • the insole has at least cutouts at least in the area in which the lower, folded end area of the lining ends, that the lower end area of the lining is embedded in a plastic material filling the cutouts of the insole in such a way that at least the surface of the end region of the lining facing the interior of the footwear forms a constant surface with the surface facing the interior of the footwear of the plastic material and the functional layer in the lower end region of the lining and at the end edge of the lining is connected to the plastic material in a watertight manner.
  • the width of the folded-over area of the feed is preferably between 1.5 and 2.5 cm, with 1.5 to 2.0 cm having proven very effective.
  • Such footwear can be produced in a simple manner by wrapping the lining around the last and then connecting the insole to the lining, for example by gluing.
  • the insole is only connected to the outer layer via the sole material.
  • the insole can also be sewn to the lower part of the outer layer.
  • the folded area of the lining is glued to the insole.
  • the width of the folded-over area of the lining depends on the fact that a sufficiently firm and watertight connection between the lining and the insole is achieved for use. As a rule, a width of 1 to 2 cm is sufficient.
  • the cut-outs in the insole allow the plastic material or the sole material to penetrate through to the lining and form a watertight connection with it. It is not necessary, as described in DE-A-38 21 602, to provide a porous connecting material, which would only make the production of the shoe unnecessarily expensive.
  • the insole is glued on with the cutouts, the insole is sewn to the folded-over part of the outer layer and then the plastic material, which is advantageously also the sole material, is injection molded on become.
  • the plastic material then penetrates through the cutouts to the lining, but can only penetrate to the last, the last advantageously being provided with a non-stick coating.
  • the lining is preferably constructed in such a way that the waterproof, water-vapor-permeable layer is coated on the inside of the shoe with a conventional lining, while the waterproof, water-vapor-permeable layer is reinforced on the outside by a textile fabric, which is on the one hand the lining gives the necessary strength and on the other hand is easily penetrable by the plastic material, so that a good waterproof connection to the waterproof water vapor permeable layer is achieved.
  • the textile fabric which can be a woven, knitted, knitted or non-woven fabric, is penetrated and enveloped by the plastic material, as a result of which the layer which gives the lining the necessary strength is sufficiently connected to the insole and / or the sole material via the plastic material.
  • connection is characterized as being sufficiently firm for the use of the shoes. This connection prevents water from penetrating into the inside of the shoe.
  • free space created by the shortened lining can be bridged by a porous material, for example a mesh or textile grid, or also by a lining sole, which can be connected to the lining, for example by sewing.
  • the footwear according to the invention is characterized in particular by the fact that the insole has a single cutout, the cutting edge of which extends at least approximately parallel to the end edge of the folded end region of the lining.
  • the plastic injection molding compound is particularly easy to feed penetrate a waterproof connection.
  • the sole material penetrates in the outer area to the insole, in the cut-out area of the insole to the lining and in the area in which there is neither insole nor lining to the last coated with an anti-adhesive.
  • the footwear according to the invention has proven particularly useful when the plastic material is connected in a watertight manner to the exposed parts of the folded area, in particular the end edge of the folded area of the lining. In this way, the edge is connected to the plastic material in a watertight manner, so that a further security against ingress of water is created.
  • the injection process is carried out in such a way that the surface of the sole material facing the inside of the shoe forms a continuous surface with the area of the lining facing the inside of the shoe. This can be guaranteed by appropriate training of the last. With such a shoe you can even do without an insole. Nevertheless, the user of the shoe has the comfort he requires, because the inner sole side forms a constant surface and thus has no annoying folds and / or gradations. It can also be advantageous here if the folded part of the lining is cut in the area of the heel and / or in the area of the toe and is connected in a watertight manner after turning over, in order to avoid wrinkling even in these critical zones.
  • the footwear according to the invention is characterized in particular by the fact that the lower end region of the lining is connected to a lining sole, the end edge of the lower folded-over region of the lining and the The outer edge of the lining sole is at a distance from one another which is filled by the plastic material in such a way that the surfaces of the lower folded-over end region of the lining, the plastic material and the lining sole facing the inside of the footwear form a constant surface.
  • the lower end region of the lining is sewn to the lining sole and the sewing threads connecting the lining and the lining sole are at least partially embedded in the plastic material.
  • these sewing threads are monofilaments, because no capillary forces can arise in the sewing thread. If multifilament yarns are used, it is advisable to impregnate them in order to fill the cavities formed in the sewing thread between the filaments with the impregnating agent.
  • the footwear according to the invention can advantageously be applied to footwear in which the lower end region of the outer layer is oriented essentially perpendicular to the underside of the outsole.
  • the plastic material especially if the plastic material is also the sole material and the outsole is injection molded, is sufficient to achieve a good connection between the lower region of the outer layer and the insole, because when the sole is molded on, the plastic material of the sole Insole and the outer layer from the outside and glued to the insole and the outer layer.
  • the footwear according to the invention has proven itself in particular in the case of so-called strobed footwear (with a Strobel sewing machine sewn), in which the lower end area of the outer layer is sewn to the insole.
  • the insole has, at least in the joint area, a porous holding structure which can be penetrated by the plastic material and is connected to the insole.
