Description

DETAILED DESCRIPTION OF THE INVENTION

FIELD OF THE INVENTION The present invention comprises a shank and a shank having an insole connected to the shank and at least partially comprising a water-tight functional layer which is particularly preferably moisture-permeable. And a shoe sealing system and method for a sealed shoe having an outsole, especially a glued outsole. The invention further relates to a method for producing such a shoe.

BACKGROUND OF THE INVENTION [0002] For example, there are shoes in which the shank portion is highly airtight by coating the upper material of the shank with a watertight layer. This is preferably a moisture-permeable functional layer by achieving watertightness while maintaining air permeability, that is, moisture permeability. The functional layer is often part of a functional layer laminate having at least one textile layer in addition to the functional layer. Special effort is required to ensure permanent watertightness of the area between the sole shank end and the sole structure.

To this end, sock-like inserts, sometimes referred to in the art as booties, have been used between the shank and the sole structure, and on the other hand internal liners have been used. Since such booties are shaped by joining cutting parts, sewing holes are not required. However, if the booties are to some extent matched to the corresponding shoe shape, there are many manufacturing conditions for using the booties. Another known method is that the lower part of the shoe structure is sealed, so that the lower part of the shank is covered with a functional layer and sewn to the insole with an optionally molded-on outsole outsole. It consists of being attached. However, it is unavoidable that water reaches the shank end on the sole side, and thus the functional layer end on the sole side, generally by capillary action in the more water-permeable shank upper material, and in particular on the shank end on the sole side. In the fiber section above the cut ends, water is reached by water bridge, and the water reaches the inner lining, which is generally very absorbent, located inside the functional layer.

[0004] This problem is overcome by the sole construction disclosed in EP 0 298 360 B1, wherein the functional layer at the shank end on the sole side has a protrusion on the upper material. The protrusions form a bridge with the mesh strip, one side of the mesh strip being sewn to the upper material and the other side being sewn to the functional layer and the insole. The functional layer protrusions are then sealed by the bottom material, which material, if it is liquid, penetrates the mesh strip during molding. If the mesh strip is particularly a monofilament mesh strip, this is typical of blocking water that has already penetrated along the upper material to the end of the shank on the sole side covered with the outsole, and as a result Moisture cannot penetrate to the cut end of the sole-side functional layer and therefore does not reach the inner liner of the shoe.

[0005] This mesh strip solution has proven very successful. In this case, since the sealing at the end of the sole-side functional layer requires integral molding of the outsole, this known method is limited to a shoe having an integral molded outsole, and is used for a glue-adhesive type outsole. Can not do. Therefore, it cannot be used for elegantly shaped shoes. The integral molding of the outsole is expensive to mold, which increases the depreciation period and necessitates the production of corresponding shoe types and corresponding shoe sizes in large quantities. Shoe designs are known in which the functional layer has protrusions on the upper material at the sole end and no mesh strip is present. This bottom material is molded directly on the functional layer at the protrusion. This method is also suitable only for one-piece outsole shoes.

SUMMARY OF THE INVENTION According to the present invention, a watertight shoe can be manufactured with relatively simple means and limited cost. In addition, the invention makes it possible to produce shoes with permanent watertightness at the sole-side shank end, irrespective of the outsole, at the lowest possible cost and with the least processing steps. The sealing shoe according to the first aspect of the present invention has a shank and an insole to which the shank is connected, in which a reactive hot melt adhesive based on polyurethane is applied to the surface, and Crimped on the sole of the shoe, and connected to the shank. The present invention also discloses a shoe manufacturing method in which a shank is connected to the outsole, according to which a reactive hot-melt adhesive based on polyurethane is applied to the shoe bottom in the middle sole, and the shank is connected thereto. And crimp. The dependent patent claims explain this variant.

In the shoe of the present invention, a reactive hot-melt adhesive containing polyurethane as a main component is applied to the surface, pressed on the midsole shoe sole, and the shank portion is connected thereto. In such a situation, the sole means the sole before applying the outsole.

[0008] Reactive hot melt adhesives are adhesives that produce water tightness when reacted.
In the shoe of the present invention, this adhesive provides sealing of the shoe structure. In one variation of the present invention, an open pore glue compatible material is applied to the entire shoe and the sides or portions of the shoe. Preferably, an upper material such as leather, non-woven fabric, felt or similar material is used as such a material. This material is preferably flash glued with a reactive hot melt adhesive. This allows
The surface of the upper material away from the insole and the surface of the reactive hot melt adhesive away from the insole will be essentially in direct contact. In this way, a situation is obtained in which the sole (in the sense described above) has a flat and uniform surface, which facilitates gluing of the outsole.

In a variant of the invention, the sole-side shank of the shoe is connected to the insole by glue fishing. This means that the fishing insert of the sole-side shank is pulled to the midsole edge on the bottom surface facing the outsole later on the sole,
It means that it is attached to the bottom edge of the middle bottom by glue bonding. After gluing, reactive hot melt adhesive is applied on the sole to seal the sole before applying the outsole.
(In the sense described above). In the case of a glue fishing shoe, the reactive hot melt adhesive is preferably applied so that the midsole and the hooked shank overlap with a width of about 1 cm. This ensures that the inner edge of the fishing insert is sealed with the reactive hot melt adhesive.

In one variation of the present invention, the reactive hot melt adhesive is applied to the entire bottom surface of the midsole not covered by the fishing insert and the portion that overlaps the aforementioned fishing insert.

[0011] In the present invention, in addition to the glue fishing by the fishing glue, seal bonding by a reactive hot melt adhesive is further generated. In the shoemaking of the present invention, normal glue fishing can be used without modification. To obtain water tightness in the sole structure, it is only necessary to apply the required reactive hot melt adhesive to the soles, which are not yet equipped with outsole. Thus, watertightness is achieved with very little additional cost.

In another aspect, the present invention relates to a sole-structured shoe having a shank and an outsole, wherein the shank comprises an upper material and a watertight feature at least partially covering the upper material inside the upper material. The sole, the sole side shank end with the upper material end and the functional layer end, the outsole is connected to the shank end, the functional layer end extends beyond the upper material end, and It has a glue bonding zone closed from the outer periphery of the bottom that is made of a reactive hot melt adhesive that provides water tightness in a reactive state and is applied to the protrusion.

According to this aspect, the present invention also relates to a method for making shoes by the following manufacturing steps: upper material,
And forming a shank comprising a water-tight functional layer at least partially covering the upper material on the inside thereof and having a shank end on the sole side; the upper material has an upper material end on the sole side, and the functional layer Providing a functional layer end on the sole side, the functional layer end comprising a protrusion extending beyond the end of the upper material; a reactive hot melt adhesive for obtaining water tightness in a reactive state, comprising: Applying a closed glue adhesive zone to the protrusion; and applying the outsole to the shank end. Useful modifications are set out in the dependent claims.

The above two aspects can be advantageously combined, ie the entire sole and the protrusions can also be covered with a reactive hot melt adhesive. The shoe of the present invention has a shank and an outsole, the shank comprising an upper material and a watertight functional layer at least partially covering the upper material on the inside, and with an upper material end and a functional layer end on the sole side. It has a shank end. The outsole is connected to the shank end. The functional layer end has a protrusion extending beyond the upper end of the upper material. A glue bonding zone consisting of a reactive hot melt adhesive that provides water tightness in the reaction state is applied to the protrusions and closed toward the perimeter of the outsole.

[0015] The sealing function achieved with conventional shoes of the type described above having this sole is that in the shoes according to the invention, the protrusions at the end of the functional layer, on the other hand, have a particularly high creep performance in the liquid state before curing. By applying a hot-melt adhesive which has, on the other hand, a particularly high and permanent watertightness in the cured state. Reactive hot melt adhesives can be applied by very simple means, such as, for example, drawing, spraying, and linear or rosary glue, and heating makes the reactive hot melt adhesive adhesive, and so on. This allows it to adhere to the protrusions before curing, so that a permanent bond with the functional layer starts at the protrusions. Thus, the watertightness of the sole structure of the watertight shoe with the desired outsole is achieved in a very simple manner with very simple processing steps. Thus, the method according to the invention makes the production of watertight shoes inexpensive.

In one variant according to the second aspect of the invention, the shank end extends essentially perpendicular to the tread surface of the outsole (see below for vertical extension) and function. The layer ends project on the upper end of the upper in the direction of the tread. In another variant of the invention, the shank end extends essentially parallel to the tread surface of the outsole (see also below for horizontal spreading) and the functional layer end extends in the direction of the center of the outsole. Protruding over the end of the upper material. The first variant is particularly suitable for a shell-shaped outsole having an end projecting perpendicular to the tread surface of the outsole. The latter variant is particularly suitable for flat outsole shoes, such as those used in more elegant shoes.

In a variant according to the second aspect of the invention, the protrusion is bridged by a connecting strip, the long side of which is connected to the end of the upper material and the long side of the opposite side is connected to the end of the functional layer. It is articulated. In another variant of the invention, the protrusions are not bridged as described above. The reactive hot melt adhesive is applied to the protruding part directly to the functional layer when no connecting strip is present, or applied to the outside of the connecting strip covering the protruding part when the connecting strip is present. . In order to seal the functional layer with a reactive hot melt adhesive in the latter case, the connecting strip is selected from a material which is permeable to a liquid or a liquid-producing reactive hot melt adhesive before curing.

The presence of the aforementioned connecting strip allows, on the one hand, a permanent watertight sealing between the end of the functional layer and the glue-bonded outsole, on the other hand, for example, finally, in the manner of strapping or tacking, The tension acting on the functional layer while pulling the end of the functional layer is directed to the entire upper material or at least a part thereof, so that it does not concentrate on the functional layer having low load capacity. Preferably, the connecting strip is made of a thermoplastic mesh material or an open mesh material formed of a fiber material such as a single fiber material. But,
The connecting strip can be of other shapes, for example, staples, large loops or long stitches or similar structures. The main role of the connecting strip is to sufficiently penetrate the appropriate flow of liquid reactive hot melt adhesive to provide a permanently watertight functional layer seal, and between the upper material and the insole material (when fishing). ) Or to reduce the load on the functional layer and to move or distribute the load in fishing with a string.

The mesh strip from Grebruder Jaeger (Uppertal, Germany) described in Article Number 23851 is suitable for the shoes according to the invention. The invention is suitable for shoes with or without insole. In the latter case, the end portions of the sole-side functional layer are hooked together by string hooking. The end of the upper material is then glued or sewn to the end of the functional layer, optionally via a mesh strip, or the end of the functional layer and the end of the upper material are hooked together by string fishing. In a variant of the invention with a mesh strip, one long side is connected to the upper end of the upper material and the other long side is connected to the end of the functional layer and optionally the midsole, preferably by sewing.

The process according to the invention for the production of a shoe according to the invention is as follows: it consists of an upper material and a watertight functional layer which at least partially covers the upper material on the inside, and a shank on the sole side Manufacture shank with end. The upper material has an upper material end on the sole side, and the functional layer has a functional layer end on the sole side, wherein the functional layer end has a protrusion extending beyond the upper material end. . The glue bonding zone is closed circumferentially on the outsole as a reactive hot melt adhesive that provides water tightness in the reactive state is applied to the protrusions. The outsole is fixed to the shank end.

In the glue bonding of the reactive adhesive to the functional layer, adhesion is particularly obtained by applying a mechanical force to the functional layer after applying the reactive adhesive onto the protrusion. Suitable press equipment is, for example, a non-porous polytetrafluoroethylene (also known as Teflon), which does not become moist with, for example, a reactive hot melt adhesive and thus does not adhere to the reactive hot melt adhesive. Preference is given to pressure cushions with a smooth surface made of material. For example, a pressure cushion such as a rubber cushion or an air cushion is preferably used for this purpose, and the pressing surface is coated with a film such as the aforementioned nonporous polytetrafluoroethylene, or is coated with such a film. Prior to pressing, it is placed between a sole structure coated with a reactive hot melt adhesive and a pressure cushion.

In one variant of the invention, the outsole is glued together with a conventional solvent or thermal adhesive, which includes, for example, an adhesive based on polyurethane.
The solvent adhesive is an adhesive which becomes tacky by adding a volatile solvent and is cured by evaporation of the solvent. Thermal adhesives are thermal adhesives called thermoplastic adhesives, which become tacky by heating and cured by cooling. Such an adhesive repeatedly returns to a tacky state by reheating.

The use of a reactive hot melt adhesive which can be cured by moisture is preferably applied to the part to be glued and exposed to moisture for curing. In one variant of the invention, a heat-activatable and moisture-curable reactive hot-melt adhesive is used, which is activated by heat, applied to the glue joint, and hydrated for curing. Has been exposed to The use of a reactive hot melt adhesive which is activated by heat and can cause a curing reaction with moisture such as steam makes the shoe making according to the invention particularly simple and economical.

[0024] A foamable reactive hot melt adhesive can also be used, if it is intended to take advantage of the increased volume of this adhesive, it will fill in voids and form in the mesh strip section. It is particularly suitable for penetrating gaps or niches to be formed. Thereby, particularly reliable watertightness can be obtained. Foaming occurs by agitation during application of the reactive hot melt adhesive, for example with a gas that is a mixture of nitrogen and oxygen.

Prior to activation, the adhesive consists of relatively short-chain molecules with an average molecular weight in the range of about 3,000-5,000 g / mol, is non-tacky, and is optionally activated by heating to lead to a reaction state. Relatively short-chain molecules crosslink into long-chain molecules, thereby hardening primarily in a humid atmosphere, which is referred to as a reactive hot melt adhesive. The adhesive has tackiness in a reacted or cured state. After curing by crosslinking, they cannot be reactivated. During curing, three-dimensional cross-linking of molecular chains occurs. Three-dimensional cross-linking results in particularly strong protection against moisture penetration into the adhesive.

[0026] Polyurethane-reactive hot melt adhesives, resins, aromatic hydrocarbon resins, aliphatic hydrocarbon resins, for example condensed resins such as the epoxy resin type, are examples suitable for the purpose of the present invention. Polyurethane reactive hot melt adhesives (hereinafter referred to as PU reactive hot melt adhesives) are particularly preferred. The crosslinking reaction of the PU-reactive hot-melt adhesive that causes curing is usually caused by moisture, which is sufficient with atmospheric moisture. In the case of a blocked PU-reactive hot-melt adhesive, such a hot-melt adhesive is in the open state, i.e., since its crosslinking reaction only starts after activation of the PU-reactive hot-melt adhesive by thermal energy. Can be stored exposed to atmospheric moisture. On the other hand, there are PU-reactive hot-melt adhesives which are not blocked, in which case the crosslinking reaction has already begun at room temperature if ambient moisture is present in the surroundings. The latter reactive hot melt adhesives must be stored protected from atmospheric moisture as long as no crosslinking reaction has occurred.

[0027] Both types of PU-reactive hot melt adhesives are usually obtained unreacted in the form of rigid blocks. Prior to application to the glue bond, the reactive hot melt adhesive is heated and melted so that it can be spread and applied. If a non-blocking reactive hot melt adhesive is used, atmospheric moisture must be removed and heated as described above. The above procedure is not required for the use of a blocked reactive hot melt adhesive, but the heating temperature must be kept below the deblocking activation temperature.

In one variant of the invention, a PU-reactive hot melt adhesive composed of blocked or capped isocyanates is used. To overcome the blocking of the isocyanate and thus activate the reactive hot melt adhesive composed of the blocked isocyanate, a thermal activation must be performed. The activation temperature of such PU reactive hot melt adhesives is roughly 70
It is in the range of ~ 80 ° C.

In another variation of the present invention, a non-blocked PU reactive hot melt adhesive is used. The crosslinking reaction can be accelerated by heating. In a practical variant of the method of the invention, a PU-reactive hot melt adhesive available under the name IPATHERM S 14/242 from HP Fuller (Wales, Austria) is used. In another variant of the invention, Henkel AG (Düsseldorf, Germany)
A PU-reactive hot-melt adhesive available under the name Macroplast QR 6202, manufactured by the Company, is used.

A functional layer having moisture permeability as well as water impermeability is particularly preferred. This allows
It becomes possible to manufacture a watertight shoe that has watertightness but remains breathable. A functional layer is considered “watertight” if it guarantees a water osmotic pressure of at least 1.3 × 10 ⁴ Pa, including sewing of any functional layer. Functional layer material is water osmotic pressure 1 × 10 ⁵ Pa
It is preferable to guarantee the above. The water osmotic pressure is measured by a test method in which distilled water is applied to a 100 cm ³ functional layer sample at 20 ± 2 ° C. while increasing the pressure. The rise in water pressure is 60 ± 3 cmH ₂ O / min. The water osmotic pressure then corresponds to the pressure at which water was first observed on the opposite side of the sample. Details of this test procedure can be found in the 1981 IS
O Standard 0811.

The “functional layer” is said to have moisture permeability when the moisture permeability value Ret is less than 150 m ² · Pa / W. The moisture permeability is tested based on the Hohenstein skin model. This test method is described in DIN EN 31092 (02/94) or ISO 11092 (19/33). Water tightness testing of shoes is performed, for example, with a centrifuge of the type disclosed in US Pat. No. 5,329,807. The centrifuge disclosed in that patent comprises four rotatable holding baskets for holding shoes. It can test 2 to 4 shoes or boots simultaneously. In this centrifuge, the centrifugal force generated by rotating the shoe at high speed is used to find a water-permeable portion. Before centrifuging, fill the inside of the shoe with water. Apply an absorbent material, such as a blotter or paper towel, to the outside of the shoe. The centrifugal force exerts pressure on the water that fills the shoe, and if the shoe is permeable, the water reaches the absorbent.

In such a water tightness test, the shoe is first filled with water. For shoes with an upper material that does not exhibit sufficient inherent rigidity, a rigid material is placed in the space inside the shank for stabilization to prevent breakage of the shank during centrifugation. Place blotting paper or paper towels on the test shoe for each corresponding holding basket. Thereafter, the centrifuge is rotated for a predetermined time. Then stop the centrifuge and check if the blotter or paper towel is moist. If wet, the shoe under test fails the water tightness test. If dry, the shoe under test passes and is considered watertight.

The water pressure during centrifugation depends on the effect of the surface effectiveness of the shoe, the size of the shoe (the inner surface of the sole), the weight of the water filled in the shoe, the radius of the centrifuge and the centrifugal speed. Suitable materials for the water tight, moisture permeable functional layer include the polyurethanes, polypropylenes and polyesters disclosed in U.S. Pat. Nos. 4,725,418 and 4,493,870, including polyetheresters and laminates thereof.
However, expanded microporous polytetrafluoroethylene (ePTFE), as disclosed in U.S. Pat.Nos. 3,953,566 and 4,187,390, is particularly preferred, and hydrophilic, for example, disclosed in U.S. Pat.No.4,194,041. Expanded polytetrafluoroethylene with an impregnating agent and / or a hydrophilic layer is particularly preferred. A microporous functional layer is understood to refer to a functional layer having an average pore size of about 0.2 μm to about 0.3 μm.

The pore size was determined by Coulter Electronics of Florida, USA (Hialeah, Florida, USA).
It can be measured by a Coulter porometer (registered trademark) manufactured by U.S.A.). The Coulter porometer is a measuring instrument for automatically measuring the pore size distribution in a porous medium using a liquid permeation method (described in ASTM Standard E 1298-89). The Coulter porometer determines the pore size distribution by increasing the air pressure over the sample and measuring the resulting flow rate. This pore size distribution is a standard for measuring the uniformity of the pores of the sample (for example, if the pore size distribution is in a narrow range,
The difference between the minimum and maximum pore sizes is shown to be limited). This value is obtained by dividing the maximum pore size by the minimum pore size. The Coulter porometer also calculates the pore size for average flow. According to that definition, half of the flow rate through the porous sample passes through pores with a diameter greater than or less than the pore diameter relative to the average flow rate.

When ePTFE is used as the functional layer, the reactive hot melt adhesive can penetrate during the glue bonding step to the pores of this functional layer, and the reactive hot melt adhesive can be mechanically bonded to this functional layer. Cause a static stop. The functional layer of ePTFE comprises a thin polyurethane layer, one side of which is in contact with the reactive hot melt adhesive in the glue bonding process and in contact with the thin polyurethane layer. The use of PU-reactive hot-melt adhesive to connect such functional layers causes not only mechanical adhesion but also chemical adhesion between the PU-reactive hot-melt adhesive and the PU layer on the functional layer . This results in a particularly tight glue bond between the functional layer and the reactive hot melt adhesive, which guarantees a particularly durable watertightness.

Leather or woven fabric is suitable as the upper material. Among the woven fabrics, woven fabrics, knits,
Includes mesh, nonwoven or felt. These fabrics are produced, for example, by natural fibers such as wool or viscose, synthetic fibers such as polyester, polyamide, polypropylene or polyolefin, or a mixture of at least two of these materials. The liner material is typically located inside the upper material of the shank. Materials similar to the above instep materials are suitable for this purpose.

If a functional layer is used, the liner material is usually located on the inside. Materials similar to those described above as the upper material are suitable as liner materials, which are often joined to functional layers in a functional layer laminate. The functional layer laminate also consists of two or more layers,
A woven backing is found on the side of the functional layer that overlaps away from the liner layer. The outsole of the shoe of the present invention may be composed of a water-tight material such as rubber or plastic such as polyurethane, or a non-water-tight but breathable material such as leather or leather with rubber or plastic targia. it can. In the case of a non-watertight outsole material, the outsole is provided with a water-tight and moisture-permeable functional layer at least in a portion where the sole structure has not obtained water-tightness by other means, while maintaining air permeability. Sex.

The midsole of the shoe of the present invention can be made of viscose, for example, a non-woven fabric such as a polyester non-woven fabric to which molten fibers are added, leather or glue-bonded leather fibers, or the like. The midsole is available from Texon Monkmuhl (Mockmur, Germany) under the name Texon Insole. The insole made of such a material has water permeability.
An insole made of such a material or another material can be made watertight by disposing a layer made of a watertight material on the surface or inside thereof. For this purpose,
A film with cap material V25 from Rhenoflex (Ludwigshawen, Germany) can be ironed. If the insole has not only water tightness but also moisture permeability, it is preferable to provide a water tight and moisture permeable functional layer preferably composed of ePTFE (expanded microporous polytetrafluoroethylene). The leather insole fitted in this way is from TOP of WLGore & Associates (Putzbrunn, Germany)
Available as DRY®.

When a mechanical force is applied to the sole after the reactive adhesive is applied to the sole, the glue adhesion of the reactive adhesive to the sole becomes particularly high. Pressing machines suitable for this purpose include reactive hot melt adhesives, which have a smooth material surface that is not moistened, and thus have no adhesion to reactive hot melt adhesives, for example non-porous polytetrafluoroethylene. A pressure cushion shape made of (known under the trade name Teflon) is preferred. The pressure cushion is preferably used for this purpose, in the form of a rubber cushion or air cushion, the compression surface of which is coated with the aforementioned material, such as non-porous polytetrafluoroethylene, or such a film, Before the pressing step, it is inserted between the sole structure coated with the reactive hot melt adhesive and the pressure cushion. The invention will be further described with respect to variants.

Detailed description of preferred variants of the invention The first variant of the invention shown in FIG. 1 comprises a midsole 1, a shank insert 2 connected to the midsole 1 by glue fishing. 2, and a reactive hot melt adhesive 3 applied to the insole 1 and the bottom surface of the last insert 2. The reactive hot melt adhesive 3 then covers the entire bottom surface of the midsole not covered by the last 2 and a portion of the last 2 adjacent to this portion of the midsole 1. In a preferred variant, the width of the overlap 3a of the reactive hot melt adhesive 3 on the last insert 2 is about
1 cm.

Such a shoe is preferably manufactured as follows: The insole 1 is first fastened to the bottom (not shown) of the last. The shank is then stretched along the last, the perimeter of the midsole bottom is provided by conventional last gluing, and the last insert 2 is pulled over the midsole bottom and glued to it. A reactive hot melt adhesive 3 is then applied to the insole 1 and the bottom of the last insert 2 and crimped there to obtain a sole with a flat and uniform surface. This manufacturing situation is shown in the side view of FIG. Thereafter, the outsole (not shown) was attached to the shoe sole provided with the reactive hot melt adhesive 3 by, for example, glue bonding. The sole or sole construction is made watertight by the reactive hot melt adhesive 3.

A second variant of the invention, depicted in FIG. 3, is that it faces away from the midsole 1 by an open-mouth glue phase solvent 4, which is flash glued into a reactive hot melt adhesive 3. FIG. 3 shows a shoe which is identical to the shoe shown in FIGS. 1 and 2, except that it is provided on a lower surface which is shown. The application of this material 4 reduces the waiting time and allows the shoes thus produced to be immediately processed further.

The side view of the second variant shoe corresponding to FIG. 2 is shown in FIG.
Instant glue bonding with reactive hot melt adhesive 3 of 4 is readily apparent. This reactive hot melt adhesive 3 is preferably applied as a tacky adhesive, in which case the flow rate is affected by the heating strength of the reactive hot melt adhesive 3.

A pressing device 5 for crimping the reactive hot melt adhesive 3 on the insole 1 and the bottom of the last insert 2 is shown very schematically in FIG. A pressure cushion of the type described above is particularly suitable for this purpose. The terms vertical and horizontal used below are used to describe the location of individual shoe components. This relates to the description of the drawings and corresponds in most cases to the idea that the shoes are arranged with their outsole on a horizontal floor or partly on a variant of a horizontal support. FIG. 5 shows a highly schematic cross-sectional view of a third variant of the shoe of the present invention, with the shank 11 configured with the upper material 13 and the functional layer 15 lining it. The functional layer 15 can be part of a functional layer laminate having a functional layer and a liner layer inside. The functional layer 15 also has a backing cloth (
(Not shown). In some variations, the functional layer and the backing are separate material layers.

FIG. 6 shows an insole 17 and a shell-like assembled outsole 19 made of rubber and / or plastic. The upper material 13 and the functional layer 15 have an upper material end 21 and a functional layer end 23 with vertical ends, that is to say perpendicular to the tread surface of the outsole 19. The functional layer end 23 has a protrusion 25 to the upper material end 21. This protrusion
25 is bridged by a mesh strip 27. The upper first long side of the mesh strip is sewn to the lower end of the upper end 21 by a first seam 29. The second long side of the lower side of the mesh strip 27 is also Strobel seam,
It is sewn to both the insole 17 and the lower end of the functional layer end 23.

A reactive hot melt adhesive 33 that provides water tightness in a cured state is applied to the outside of the mesh strip 27. In a liquid state where the reactive hot melt adhesive reaches, for example, by heat, the reactive hot melt adhesive 33 penetrates the mesh strip 27 and penetrates the protruding portion 25 outside the functional layer. In the next cured state, the reactive hot melt adhesive 33 seals this part of the functional layer 15 in a watertight manner. It is preferable that the reactive hot melt adhesive 33 is further applied in such an amount and amount that the cut end of the functional layer 15 is sealed at the lower end of the functional layer end portion 23. The periphery of the insole 17 adjacent to the functional layer end 23 and the fastening seam involving the functional layer 15 are also preferably sealed.

Water and other liquids that penetrate along the water- or liquid-introducing upper 13 to the lower end of the upper end 23 cannot reach the inside of the functional layer 15 and therefore The inner lining of the shoe cannot be reached, because it is sealed by the reactive hot melt adhesive 33. The outsole adhesive 35 is preferably applied to the entire inside of the outsole 19, in which case a regular outsole adhesive in the form of a solvent adhesive or a hot adhesive may be involved.
Further, the outsole adhesive 37 can also be applied to the upper material 13 outside. The first variant of the shoe shown in FIG. 1 is glued to the midsole 17 and the shank end of the sole side, so that it is facing up against the midsole 17 before the outsole 19. Is crimped. The outsole adhesive 35 reaches inside the shell end 40 of the outsole 19 and glues with the outsole adhesive 37 applied to the shank end.

For better explanation and clarity, the gaps between the individual components of the shoe structure are
It is drawn larger than it actually is in drawings 6 and later. The gap between the individual components is actually the required size, so that after crimping on the midsole 17 of the outsole 19,
The shell end 40 is located closely against the outside of the upper material 13 and is glued to the upper material 13. FIG. 7 largely corresponds to the first variant shown in FIG. 6, but in the second variant only the upper end 21 ends vertically and the functional layer end 23 ends horizontally. 4 shows a fourth variant of the shoe according to the invention, ie, parallel to the tread surface of the outsole 19 and somewhat different from the first variant. Thus, the protrusion 25 at the end 23 of the functional layer, and essentially the mesh strip 27 and the reactive hot melt adhesive 33, extend horizontally. Due to the extent of the horizontal functional layer end 23, the insole 17 is no wider than the entire sole width of the shoe structure and its periphery is remote from the vertical part of the shank 11. On the other hand, with respect to additional aspects of the second variant, what has been said above for the first variant is consistent with the first variant.

FIG. 8 shows a fifth variant of the invention, in which both the upper part end 21 and the functional layer end 23 extend horizontally, which means that in this variant, the mesh This leads to the strip 27 and the reactive hot melt adhesive 33 spreading almost horizontally. Such a shoe design, unlike the first and second variants, does not require the vertical edge of the shank 19 to be included by the shell edge of the shell-like outsole,
Enables the use of flat outsole 39. For this reason, any outsole that is desirable for an elegant shoe, for example a leather sole, can be used for the third variant. Due to the almost horizontal tread surface of the outsole 39, the outsole adhesive 33 applied to the outside of the upper material 13 is applied to the horizontally extending upper material end 21.

The fifth variation shown in FIG. 8 is shown in FIG. 9 as a partially broken view excluding the outsole. This figure shows a last 41 and a state where the shank 11 is pulled so as to cover the last 41. Unlike FIG. 8, the individual liner layer 43 is shown inside the functional layer 15 in FIG. FIG. 4 shows the shoe design with the reactive hot melt adhesive applied only to the bottom surface of the mesh strip 27, but not forced through the mesh strip 27 to the functional layer end 23. I have.

FIG. 10 also shows the shoe design of FIG. 9 in a partially broken perspective view after gluing the outsole 39 to the bottom of the midsole 17 and to the bottom of the vertical portion of the shank 11. In this figure, the last 41 has already been removed from the shoe. For better explanation, the sole structure is shown enlarged in a circular cutout. In summary, at this stage of production, the reactive hot melt adhesive 33 has already penetrated into the functional layer 15. FIG. 11 has been partially cut to show the portion of the shoe where the cut of FIG. 10 was made,
FIG. 11 shows a perspective view of the entire shoe shown in FIG. FIG. 12 shows a sixth variant of the shoe according to the invention, which is identical to the third variant shown in FIG. 6, except that in the sixth variant no mesh strip 27 is present. Thus, the previous description of the third variant can be referred to substantially.

In the sixth variant, the connection between the lower end of the upper material end 21 and the lower end of the functional layer end 23 and the midsole 17 is before the glue bonding of the outsole 19 and the reactivity of the shank end. It does not exist before glue bonding to the hot melt adhesive 33. Reactive hot melt adhesive
Only after the application of 33, there is an articulation, which is not necessarily required, the upper end 21 and the function when the reactive hot melt adhesive 33 is applied to the area including the lower end of the upper end of the upper. This is due to its glue bonding action between the layer ends 23. After gluing to the midsole 17 and the shank 11 of the outsole 19, the upper end 21 also becomes a shell edge 40
The side is fixed by.

In a seventh variant shown in FIG. 13, the upper end 21 of the upper material has a fixed glue outside the functional layer 15.
Except for being fixed by 43 only, this corresponds to the sixth variant shown in FIG. Thereby, the shank 11 can be more easily handled in the manufacturing process before gluing the outsole 19 to the glue. The eighth variant of the invention shown in FIG. 14 shows a shoe structure which is identical to the fourth variant of FIG. 7, except that no mesh strip is present. Regarding the point of coincidence with the fourth variant, the description regarding FIG. 7 can be referred to. As in the case of the sixth modification shown in FIG. 12, the reactive hot melt adhesive 33 of the eighth modification is also provided with the functional layer end portion 23.
Is applied directly to the outside of the projection 25 of the base, which results in a glue bond which seals the functional layer end 23 with the reactive hot melt adhesive 33 particularly well.

In the sixth variation of FIG. 14 corresponding to the sixth variation of FIG.
Not shown between the upper end 21 and the outside of the functional layer 15. Therefore, the upper end 21 is roughly placed outside the functional layer 15 before gluing with the reactive hot melt adhesive 33 and before gluing the outsole 19.

FIG. 15 shows a ninth variant which represents a modification with respect to the eighth variant shown in FIG. 14, which comprises an additional manufacturing step, namely the midsole 17 of the functional layer end 23. When the upper end 21 of the upper layer is fixed by the fixing glue 43 outside the lower end of the vertical portion of the functional layer 15 before the sewing to the sewing is performed, application of the reactive hot melt adhesive 33 and the outsole are performed. 19 represents glue bonding. In another state, the preceding description of the preceding drawings:
It refers to the seventh variant.

The tenth variant of the invention shown in FIG. 16 corresponds to the fifth variant shown in FIG. 8, except that no mesh strip is present. Thus, the above description regarding FIG. 8 can be largely referred to. Similarly, in the tenth variant, the reactive hot melt adhesive 33 is supposed to have the end 21 of the horizontal upper material end, the peripheral edge of the midsole 19 and the Strobe
The seam 31 is applied directly to the outside of the protrusion 25 of the functional layer end portion 23 to the extent that the seam 31 is included in the seal by the reactive hot melt adhesive 33. In this modification, the gap between the functional layer 15 and the upper end portion 21 is not fixed by glue bonding. The eleventh modification shown in FIG. 17 is the tenth modification shown in FIG. 16 except that the end 21 of the upper end of the upper material is fixed outside the functional layer end 23 by the fixing glue 43. Matches the variant.

FIG. 18 of a twelfth variation of the present invention shows a shoe without an insole or with an insole in the indicated area of the shoe. For example, without the insole inside the toe,
There are shoes configured for the length of the shoe, such that the rest of the shoe has an insole. Since the shoe or portion of the shoe shown in FIG. 18 does not include an insole, the components of the vertical shank portion, namely the horizontal upper material end 21 and the horizontal functional layer end 23, are aligned in their horizontal position. Must be fixed in a separate way. For this purpose, string fishing 45 is used, whereby the functional layer ends 23 are tied together with a string. This string fishing 45 has a loop-like string hole 49 extending over the entire inner periphery of the functional layer terminal portion 23, in which the string 51 is disposed, whereby the functional layer terminal portions 21 are bound to each other. The shank is stretched over the last (not shown in FIG. 18).

In this variant, the mesh strip 27 is sewn along one long side to the upper end 21 of the upper and the other long side along the string hole 49 of the string fishing 45, and as a result The protrusion 25 is bridged by a mesh strip 27 and
21 is kept horizontal. A reactive hot melt adhesive 33 is applied to the bottom of the mesh strip 27, which in a reacted state provides a watertight sealing of the functional layer 15 in the region of the functional layer end 23. Reactive hot melt adhesive 33 may be provided, if possible, with string straps 45 and / or mesh strips 27 and an
It is dimensioned to include a seam 29 between 31.

After the application of the reactive hot melt adhesive 33, the plate-like outsole 39 is glued on the bottom surface of the horizontal shank region by the outsole glue 37. Although not shown in FIG. 18, the outsole glue can be applied to the bottom surface of the upper end 21 before the outsole 39 is glued in this variation. FIG. 19 does not have a mesh strip, but has a second string fishing 47 for this purpose, except that it binds the upper material ends 21 together in a horizontal position.
19 shows a thirteenth modification that corresponds to the twelfth modification shown in FIG. In this variant, the reactive hot melt adhesive 33 is applied directly to the outside of the protrusion 25 at the end 21 of the functional layer.

The second strap fishing 47 has a loop-like strap hole 49 which extends over the entire inner periphery of the upper end 21 and in which the strap 51 is arranged, whereby the upper End
