Definitions

  • the invention relates to a shoe with a shaft and a substantially watertight lining lying against the inside of the shaft, a fastening edge of the shaft being connected to a midsole, a watertight connecting strip resting on the outside of the fastening edge and this waterproof connecting strip having at least one has a waterproof layer-connected sole construction, and the water flow of the fastening edge to the midsole is interrupted.
  • a layer of sealant is furthermore arranged between the waterproof lining on the one hand and the shaft or the edge strip on the other.
  • the connecting strip surrounds the fastening edge of the shaft and the inner lining in a U-shape, that the inner leg of the U-shaped connecting strip is connected to the essentially waterproof lining in a watertight manner and that the U-shaped connecting strip is connected to the Midsole is connected.
  • the proposed solution enables that no further special measure has to be provided both for the fastening edge of the upper and for the area between the waterproof lining and the upper in order to achieve a good water seal of the entire shoe.
  • the U-shaped encompassing connecting strip and the watertight connection between the waterproof lining and the connecting strip prevent in a simple manner that water can pass from the upper into the interior of the shoe at the end of the upper or the fastening edge.
  • the midsole can be formed by an insole to which the connecting strip is attached.
  • the connecting strip can be attached to the insole by gluing, in particular by gluing using a hot melt adhesive layer as part of an AGO lasting process.
  • the AGO lasting process is an easy to control manufacturing process, especially for the industrial production of the shoe according to the invention.
  • the inner leg of the connecting strip which on the one hand rests on the waterproof lining, is attached on the other hand to the insole.
  • the connecting strip in its web area, i.e. outside the end of the fastening edge and the waterproof lining to which the insole is connected.
  • a flexible sole can also be provided for the midsole.
  • the midsole is connected to the connecting strip by a connecting seam, in particular by a strobe seam. Since the connecting seam can be produced particularly easily, for example on a strobe machine, such a shoe structure can be provided in particular for cheap shoes or, because of its particular flexibility, in sports shoes.
  • the connecting seam penetrate the connecting strip in its web region, ie outside the end of the fastening edge and the waterproof lining .
  • the waterproof lining can have a different structure.
  • the waterproof lining which preferably reaches into the entry area of the shoe, is formed only by a single waterproof layer.
  • the essentially waterproof lining can be vapor-permeable, for which purpose, for example, a film made of stretched polytetrafluoroethylene, a polyester membrane or a microporous polyurethane layer can be provided.
  • the essentially waterproof lining can, however, also be made up of a waterproof or vapor-permeable layer and an inner and / or an outer, textile-like coating or layer. Both the inner and the outer textile-like coating can be made of a fabric, e.g.
  • both coatings have i.a. the task of protecting the essentially waterproof layer of the lining from mechanical damage and, in addition, in particular the inner textile-like coating, to enable good wearing comfort.
  • the inner leg of the connecting strip which lies against the waterproof lining penetrates the textile-like layer in such a way that it is watertightly connected to the waterproof lining.
  • connection strip can be attached particularly easily to the fastening edge and to the lining lying against the shaft when it is open is sprayed onto the fastening edge and onto the lining lying against the fastening edge.
  • connecting strip be made of rubber with a Shore hardness in the range of approximately 50 to 80, preferably approximately 60 to 70.
  • the sole construction can also have a very different structure.
  • the sole construction is only formed by an outsole.
  • the sole construction can be formed by an outsole and a damping wedge arranged between the outsole and midsole, which improves the running and damping properties, wherein this is preferably made of an inherently waterproof material to form the waterproof layer of the sole construction.
  • the inherently waterproof layer of the sole construction is formed by a waterproof, possibly vapor-permeable film.
  • the outsole can be made of rubber with a Shore hardness in the range from approximately 50 to 80, preferably from approximately 60 to 70, and the possibly present damping wedge made of PU foam with a Shore hardness in the range from approximately 50 to 70, preferably from about 55 to 60.
  • the sole construction on its side facing the structure of the upper and connecting strip on the one hand and the midsole on the other hand have a shell-shaped design.
  • the particularly good water resistance enables the shoe to be designed as a high-profile shoe, in particular sports or hiking boots. But there is also the possibility that it is designed as a shoe.
  • the U-shaped connecting strip is applied to the upper, while the upper protrudes downward substantially perpendicularly to the midsole plane and that the fastening edge, including the lining and connecting strip, is placed on and on the midsole the midsole is attached.
  • the U-shaped connecting strip applied to the shaft with its inner leg resting against the midsole and with its web resting against the midsole edge is sewn to the midsole by means of a connecting seam, in particular a strobing seam, and then the connecting strip including the fastening edge and waterproof lining is folded over 180 ° around the edge of the midsole.
  • an inventive shoe is generally designated 10. It has a shaft 12 made, for example, of leather or a textile-like fabric, and a lining 14 which is essentially waterproof and lies against the inside of the shaft 12.
  • a mounting edge 12a of the shaft 12 and the substantially waterproof lining 14 are surrounded by a molded, U-shaped connecting strip 16.
  • the inner leg 16b of the connecting strip 16 is connected with its inner side in a watertight manner to the lining 14 and with its outer side to a midsole 18.
  • a further advantage of the invention is that the material for the connecting strip 16 is relatively small despite a very good seal.
  • the essentially waterproof lining 14, which preferably extends to the entry edge of the shoe 10, has a layer-like structure made of an outer, textile-like protective coating 14a, a vapor-permeable but essentially waterproof film 14b, such as is offered, for example, under the Gore-Tex trademark, and an inner, also textile-like protective coating 14c.
  • the outer and inner textile-like protective coating 14a, 14c can be made, for example, from coarse-mesh polyester or polyamide fabric.
  • the inner leg 16b of the U-shaped connecting strip 16 penetrates the inner, textile-like protective coating 14c of the lining 14 and lies water-tight on the vapor-permeable film 14b (see Fig. 1).
  • the outside of the inner leg 16b of the connecting strip 16 is connected to the midsole 18 designed as an insole by means of a lasting method, in particular an AGO lasting method.
  • the connecting strip 16 can be made from different materials with a Shore hardness in the range from approximately 50 to 80, preferably from approximately 60 to 70.
  • a material is selected which is flexible and spatially deformable to such an extent that the connecting strip, together with the shaft and chuck surrounded by it, can be bent or folded over easily and without deformation.
  • the structure of the shaft 12, lining 14 and connecting strip 16 on the one hand and the insole 18 on the other hand is carried by a sole construction 20 which consists of an outsole 20a and a damping wedge 20b.
  • the damping wedge 20b has a circumferential shoulder along which the connecting strip 16 which surrounds the shaft 12 and the chuck 14 rests.
  • the top of the damping wedge 20b is cup-shaped.
  • the outsole 20a can be made of rubber (rubber) with a Shore hardness in the range of approximately 50 to 80, preferably approximately 60 to 70.
  • a PU foam with a Shore hardness of approximately 50 to 70, preferably approximately 55 to 60, can be provided as the material for the damping wedge.
  • the shaft 12 and the inner lining in the area of the fastening edge 12a of the shaft 12 are overmolded with the connecting strip 16 in a U-shape, the shaft 12 and the inner lining 14 projecting downward beyond the midsole plane.
  • the structure consisting of shaft 12, lining 14 and connecting strip 16 is then turned through approximately 90 ° folded and glued to the midsole or insole 18 in a lasting process, in particular an AGO lasting process.
  • the connecting strip 16 is gripped by collets (not shown), pulled over a last L and pressed against the insole 18, a quick-curing hot-melt adhesive being introduced between the outer side of the inner leg 16b of the connecting strip 16 and the insole 18 (cf. Fig.
  • the hot melt adhesive has the advantage that it hardens in the lasting machine in a relatively short time, so that the dwell time of the shoe is reduced when tweaking in the lasting machine.
  • the structure formed in this way consisting of the shaft 12, lining 14 and connecting strip 16 on the one hand and the insole 18 on the other hand, is glued to the sole construction 20, in particular likewise by means of a hot melt adhesive layer 22.
