Description

DETAILED DESCRIPTION OF THE INVENTION

FIELD OF THE INVENTION The present invention relates to a shoe having an upper and an insole, the upper being coupled to the upper and being sealed, in particular an upper which is fitted to the underside of the insole. The upper is provided with a waterproof upper functional layer made of a foil-like material, and the upper functional layer is preferably moisture-permeable, and furthermore, the outsole adhered to the underside of the fishing section. And a sealing method for a shoe having:

BACKGROUND OF THE INVENTION [0002] Shoes exist in which the upper region is made denser by, for example, stretching an upper material having a waterproof layer. The waterproof layer is preferably a waterproof functional layer that allows water vapor to pass therethrough, thereby achieving waterproofness for maintaining respiratory activity, that is, moisture permeability. The functional layer is often part of a functional layer laminate having at least one fiber layer in addition to the functional layer. Shoes of this kind are equipped with a functional layer in the form of a so-called votier, which covers the entire interior of the shoe, or only the upper is coated with a functional layer. In the latter case, special efforts are required to ensure waterproofness in the area between the bottom instep and the bottom structure.

[0003] In shoes manufactured by the known adhesive winding method, the upper is adhered to the lower side of the midsole along a marginal area called a fishing portion, and the outsole is formed to the lower side of the bonded unit. It is attached. This structure has weaknesses. Weaknesses are particularly where the shoe contour has a small curvature and wrinkles of the upper material hooked into the hooked portion occur. This is because the glue adhesive does not previously seal the entire transition area between the upper and the insole, especially in the area of the wrinkle wrinkles, or breaks due to bending loads when using the shoe, and as a result This is because there is a danger of becoming sexual.

[0004] It is known from DE 40 00 156 A to arrange a sealing adhesive between the insole periphery and the functional layer of the upper. The midsole is equipped with a midsole waterproofing layer to prevent water reaching the lower side of the midsole through the outer material of the upper and the fishing line and reaching the inside of the shoe. There may be additional steps to adhere the insole periphery to the functional layer, and there may be instances where the use of a waterproof insole is not desired.

[0005] In the method known from EP 0 286 853 A, which seals the sloping part of the shoe upper with a waterproof, moisture-permeable functional layer, the inner rim area of the sizing part is not glued during the gluing glue, After the process of lowering the underside of the basin, an injection mold having a sealing lip upright against the basin is applied. At this time, the sealing lip substantially follows the contour of the midsole edge and is shifted slightly toward the center of the midsole with respect to the outer contour of the outsole to be attached later. Inject the sealing material into the space formed between the sealing lips. The sealing material surrounds, and thereby seals, the marginal area of the upper with the functional layer, which has not been glued during the gluing process. Although this sealing method has a reputation, it is premised on an injection mold and an injection molding machine of the kind described above. According to EP 0 595 941 B, in a shoe having an upper which is provided with a waterproof layer and which is sewn around the insole, the edge of the upper area to be shunted before the staking process is made of a waterproof material such as, for example, polyurethane (PU). It is known to seal a fishing part by embedding. This sealing method is also well established, but requires an additional method step of burying the end of the catch.

SUMMARY OF THE INVENTION According to the present invention, a shoe that can be made waterproof with relatively simple means and at a low cost is provided. Furthermore, the invention provides a shoe which is manufactured by means of a fishing method and which allows the fishing area to be permanently waterproofed with as little mechanical costs as possible and with as few method steps as possible. In one aspect of the invention, the shoe has an insole joined to the upper, and a polyurethane-based reactive hot melt adhesive on the sock side in the region of the insole and the upper part joined thereto. The agent is applied in a plane and pressed. According to the present invention, the upper is bonded to the insole, and a polyurethane-based reactive hot-melt adhesive is applied to the sock side in the area of the insole and the area of the upper connected to the insole and pressed. A method for making a shoe is also provided. The dependent claims describe embodiments of this shoe.

In the shoe according to the invention, a polyurethane-based reactive hot-melt adhesive is applied to the sock side in the region of the insole and the upper part joined thereto, and is pressed. The lower side in this context means the lower side of the shoe before the outsole is attached. The reactive hot-melt adhesive is an adhesive that produces waterproofness after the reaction is completed. This adhesive causes sealing in the area of the sole structure in the shoe according to the invention.

In an embodiment of the invention, an adhesive-friendly material with open cells is applied over the entire shoe and the side areas, or at those parts. As such a material, leather, fleece, felt or the like is preferably used. This material,
It is preferable that the adhesive is bonded so as to extend in the same plane in the reactive hot melt adhesive. This means that the surface of the facing facing away from the insole extends substantially flush with the surface of the reactive hot melt adhesive facing away from the insole. In this way, the sock side (in the sense defined above) has a flat and even surface, which facilitates, for example, bonding of the outsole.

[0009] In an embodiment of the invention, the bottom side upper part of the shoe is connected to the insole by fishing glue. That is, the fishing area of the bottom instep portion, which is stretched downward at the edge of the insole toward the rear outsole, is fixed to the lower peripheral portion of the insole by bonding. After gluing in, the reactive hot-melt adhesive is applied (in the sense indicated above).
Apply to the sock side and seal the sock side before attaching the outsole. In the case of a shoe which has been glued in, it is advantageous to apply the reactive hot-melt adhesive by overlapping the insole and the garmented upper with a width of about 1 cm. Thereby, it is achieved that the inner peripheral portion of the fishing portion is securely sealed by the reactive hot melt type adhesive.

In an embodiment of the present invention, the reactive hot-melt adhesive is applied to an area where the lower part of the midsole which is not covered by the hooking portion overlaps the above hooking portion. Therefore, in the present invention, in addition to the anchoring bonding by the anchoring part adhesive, another sealing adhesive by a reactive hot melt adhesive is performed.

[0011] To make a shoe according to the invention, conventional fishing methods can be used without change. In order to obtain waterproofing in the region of the sole structure, it is only necessary to apply a reactive hot-melt adhesive to the socks which are not yet equipped with the outsole. Waterproofing is therefore achieved with very little additional cost. In another aspect, the invention features an insole having an insole lower side, a) an insole having an insole lower side, and b) an upper shell formed by a facing and having a bottom end region. C) a waterproof upper layer with a bottom end region at least partially covered by the outer material of the upper layer, and d) the upper layer is It has a fishing part, and this fishing part is adhered to the lower part of the middle bottom by the fishing part adhesive, and the lower part of the fishing part facing away from the lower part of the middle bottom, and the end face of the fishing part facing the center of the middle bottom E) further having an outsole bonded to the underside of the fishing section by an outsole adhesive; and f) a reactivity that produces waterproofness when the reaction is completed as the fishing section adhesive. The present invention relates to a shoe to which a hot-melt adhesive is applied.

In this aspect, the present invention further provides: a) an insole having an insole lower side; b) an upper formed by a facing and having a bottom end region; A top layer that is at least partially covered inside the upper and has a waterproof upper layer with a bottom end region; and d) the upper further has a lower underside. E) a method of making a shoe having an outsole, f) first gluing the insulated portion to the lower insole with an insulated portion adhesive; Bonding the bottom to the underside of the hook with a bottom adhesive; and h) using a waterproof, reactive hot-melt adhesive as the hook-in adhesive.

In the method according to the invention according to this feature, the use of a reactive hot-melt adhesive, which gives a waterproof property in the cured state or in the completed state, as a tacking adhesive, enables the desired tacking in the tacking area. Water resistance is achieved. Both features of the invention can be combined with each other. Therefore, in addition to using the reactive hot melt type adhesive as the fishing line adhesive, it is possible to cover the sock side with the reactive hot melt type adhesive and press it. The waterproofness of a shoe can be tested, for example, by means of a centrifuge of the type described in US-A-5329807. By using a reactive hot-melt type adhesive that cures to waterproofness as the hooking part adhesive, the water that reaches the fishing part through the surface material of the upper that guides the water,
The functional layer is prevented from entering the inside facing away from the facing and thus into the shoe. This danger is particularly great if there is a highly absorbent backing inside the functional layer. The reactive hot-melt adhesive used as the fishing line adhesive according to the present invention, even after a bending load is applied when walking while wearing shoes, particularly ensures the fishing line including critical fishing wrinkles, And seal continuously.

In an embodiment of the present invention, a reactive hot-melt type adhesive is used as both the fishing line adhesive and the bottom sole adhesive. In this case, such a reactive hot-melt adhesive is first applied as a change-over adhesive before the fishing process, and after the fishing process, such a reactive hot-melt adhesive is applied to the outsole adhesive. And apply it to the underside of the fishing section to firmly adhere the outsole. A reactive hot-melt adhesive acting as an adhesive at the hooking portion and a reactive hot-melt adhesive acting as an outsole adhesive are applied and bonded to each other as an adhesive envelope, thereby providing a cover material and function of the upper. The bottom end area of the layer is waterproofly surrounded or surrounded. The result is an enhanced sealing function, as described in more detail below.

When manufacturing shoes, the reactive hot-melt adhesive acting as an outsole adhesive can be applied temporally after applying the reactive hot-melt adhesive acting as a hook-in adhesive. The dip adhesive still functions, and the outsole adhesive can be chemically bonded to the dip adhesive to be joined as a common integral adhesive enclosure. However, the outsole adhesive can also be applied to at least its free surface only after the tacking adhesive has first cured, or even after the tacking adhesive has cured. In this case, a mechanical connection having sufficient mechanical strength and waterproofness is generated between the fishing line adhesive and the outsole adhesive.

In the embodiment in which the reactive hot-melt type adhesive is used only as the hook-in part adhesive, and in the embodiment in which the reactive hot-melt adhesive is used as the hook-in part adhesive and the bottom sole adhesive, The process is performed as in a conventional fishing method using a conventional adhesive. Thus, in the method according to the invention, a waterproofing in the area of the catch-in is achieved without additional method steps or additional auxiliary measures. It is only necessary to replace the conventionally used barge adhesive with a reactive hot-melt adhesive provided according to the invention.

The shoe according to the present invention comprises an insole having an insole lower side, an upper formed by a top material and having a bottom end region, and a top material of the upper inside the upper. At least partially covered and provided with a waterproof instep functional layer having a bottom end region, and the instep has a hook-in portion, and this hook-in portion is provided with a hook-in adhesive. Adhered to the lower part of the insole, and has a lower part of the fishing part facing away from the lower part of the insole, and an end face of the fishing part facing the center of the inner sole, and is further adhered to the lower part of the fishing part by the outsole adhesive. And a waterproof reactive hot-melt adhesive is applied as an adhesive for the fishing-in part.

In the embodiment of the present invention described above, the shoe further has a reactive hot-melt adhesive as the outsole adhesive. In this case, the fishing line adhesive and the bottom adhesive cooperate to form an adhesive envelope that surrounds the top material and also the bottom end region of the upper insulated layer in a waterproof manner. A method of making a shoe according to the present invention comprises an insole having an insole lower side, an upper formed by a top material and having a bottom end region, and a top material of the upper inside the upper. At least partially covered with a waterproof instep functional layer having a bottom end region, and the instep has a hooked portion with a hooked portion underside, and Has a bottom. In this case, the fishing part is first bonded to the lower part of the middle bottom with the fishing part adhesive. Next, the outsole is adhered on the lower side of the fishing section using an outsole adhesive. A waterproof reactive hot-melt type adhesive is used as the adhesive for the fishing-in part.

In the above embodiment of the present invention, the outsole adhesive is applied while the hot-melt adhesive applied as the hook-in adhesive still has a reactive force or after its curing or reaction is completed. I do. The tack-in adhesive and the outsole adhesive are applied, and together they form an adhesive envelope that waterproofly surrounds the top material and also the bottom end region of the upper functional layer. To make the shoe according to the invention, no process steps other than those required for the conventional adhesive winding of outsole shoes are required. Therefore, in order to obtain a waterproof shoe as already mentioned, an additional method step required in shoes made according to the publications mentioned at the outset is to use a reactive hot-melt type adhesive as the glue adhesive Not necessary except to do. That is, in the manufacturing method according to the present invention, the injection molding die for charging the sealing material and the additional machine, and further the additional sealing adhesive between the inner peripheral edge and the functional layer, the fishing process is also performed. There is also no need for a method step in which the free end of the catch must be surrounded by a sealing material before it can be performed. The method according to the invention therefore makes the production cost of waterproof shoes so low that it cannot be achieved by known methods.

The adhesive, referred to as a reactive hot melt adhesive, consists of relatively short molecular chains, prior to activation, having an average molecular weight in the range of about 3000 to about 5000 g / mol;
Moreover, although it has no adhesive strength, it is brought into a reaction state after being thermally activated as required, and a relatively short molecular chain is crosslinked into a long molecular chain and hardened. And this is done in a humid atmosphere. The adhesive has an adhesive force during the reaction time or the curing time. After crosslinking and curing, the adhesive cannot be activated again. Upon completion of the reaction, a three-dimensional cross-linking of the molecular chains is caused, which causes the reactive hot-melt adhesive which has completed the reaction to be waterproof and produces an effective sealing. The three-dimensional crosslinking very strongly prevents water from entering the adhesive. This effective sealing and water entry protection is very important in the area of the bottom structure.

Particularly suitable for the purposes of the present invention are polyurethane-based reactive hot melt adhesives (hereinafter referred to as PU reactive hot melt adhesives). Further suitable are resins, aromatic hydrocarbon resins, aliphatic hydrocarbon resins and condensation resins, for example epoxy resins (EP). The crosslinking reaction of the PU-reactive hot-melt adhesive causing the curing is normally triggered by moisture, for which moisture in the air is sufficient. Since the crosslinking reaction of the blocked PU reactive hot melt adhesive can be started only after activating the PU reactive hot melt adhesive by thermal energy,
Such hot melt adhesives can be stored in an open, ie, humid environment in the air. On the other hand, if the unblocked PU reactive hot melt adhesive is present in a humid environment in the air, the crosslinking reaction already takes place at room temperature. Such a hot-melt adhesive must be protected from moisture in the air while it is not allowed to undergo a crosslinking reaction.

Both types of PU-reactive hot-melt adhesives are normally present in a rigid mass in the unreacted state. Before applying the hot-melt adhesive to the area to be bonded, the adhesive is heated and melted to make it ready for application or application. If non-blocked hot melt adhesives are used, such heating must be performed with the exclusion of moisture in the air. This is not necessary when using a blocked hot melt adhesive, but care must be taken that the heating temperature is below the activation temperature for deblocking.

In an embodiment of the present invention, a PU reactive hot melt adhesive formed by a blocked or modified isocyanate is used. Thermal activation must be performed to overcome isocyanate blocking and thus activate the reactive hot melt adhesive formed by the blocked isocyanate. The activation temperature of such PU reactive hot melt adhesives is in the range of approximately 70-170C. In another embodiment of the present invention, an unblocked PU reactive hot melt adhesive is used. The crosslinking reaction can be accelerated by heat supply. In a practical embodiment of the method according to the invention, P. A PU-reactive hot melt adhesive sold under the trade name IPATHERM S14 / 242 by Fuller (Wealth, Austria) is used. In another embodiment of the present invention, a PU reactive hot melt adhesive sold under the trade name Macroplast QR6202 from Henkel (Dusseldorf, Germany) is used.

Reactive hot-melt type adhesives whose physical and chemical properties are coordinated with each other and which cooperate to form a waterproof adhesive enclosure for the dip adhesive and the outsole adhesive Use agent. That is, the outsole adhesive adheres tightly to the pre-applied fishing tack adhesive in a waterproof manner and chemically and / or mechanically. The same reactive hot-melt adhesive can be used for the landing section adhesive and the outsole adhesive. The use of a reactive hot-melt adhesive that is thermally activatable and can initiate a curing reaction with moisture, for example water vapor, makes the production of shoes according to the invention particularly simple and economical.

When it is desired to use a reactive hot-melt adhesive whose initial strength is too small due to an extremely long physical coagulation time, the coagulation time is sufficiently short and the reactive hot-melt adhesive hardens sufficiently. Until a proper adhesive action is achieved, a thermoplastic that initially takes on the adhesive function can be blended with the reactive hot melt adhesive. Thermoplastic refers to a non-reactive polymer incorporated into a reactive hot melt adhesive. In particular, a polyurethane-based reactive hot-melt adhesive (hereinafter referred to as a PU-reactive hot-melt adhesive) is advantageous. Suitable thermoplastics which can be incorporated into the PU-reactive hot melt adhesive are, for example, thermoplastic polyesters and thermoplastic polyurethanes.

It is advantageous if the upper layer is not only waterproof but also permeable. This makes it possible to produce waterproof shoes that perform breathing activities despite being waterproof. The functional layer may include at least 0.1 seams, including any seams provided in the functional layer.
It is considered "waterproof" if it guarantees a permeation pressure of 3 bar. Functional layer material is 1b
It is preferable to guarantee a permeation pressure of at least ar. In this case, the water permeation pressure is measured by a test method in which distilled water at 20 ± 2 ° C. is pressed against a test subject of 100 cm ² of the functional layer while increasing the pressure. The water pressure is 60 ± 3 cmWs per minute. The permeate pressure is then equal to the pressure at which water appears on the other side of the subject. For details on how to do this,
It is specified in 1981 edition ISO standard 0811.

When the functional layer has a moisture permeability coefficient ret of 150 m ² · Pa · W ⁻¹ , the “moisture permeability”
Is considered. Moisture permeability is tested by the Hohenstein skin model. The test method is DINEN 31092 (02 (94) or ISO 11092 (19
/ 33). The waterproofness of shoes or boots can be tested by the centrifugation method according to US Pat. No. 5,329,807 described above. The centrifuge described there has four holding baskets for holding shoes, which are pivotably held. This allows two or four shoes or boots to be tested at the same time. In this centrifuge, the centrifugal force generated by the high-speed centrifugation of the shoe is used to find the waterproof part of the shoe. Inject water into the shoe before centrifugation. On the outside of the shoe is placed an absorbent material, such as a blotter or paper towel. The centrifugal force exerts pressure on the water injected into the shoe, which causes the water to reach the absorbent material if the shoe is not tight.

In such a waterproof test, water is first injected into shoes. In the case of shoes using a surface material that does not have sufficient intrinsic strength, a rigid material is placed inside the upper for stabilization to prevent the upper from shrinking during centrifugation. A blotter or paper towel is placed in each holding basket, on which the shoes to be tested are placed. The centrifuge is then turned on for a specific time. The centrifuge is then stopped and the blotter or paper towel is checked for dampness. If wet, the shoe did not pass the waterproof test. If dry, the tested shoe passes the test and is rated as a waterproof shoe. The pressure applied by water during centrifugation depends on the size of the shoe.
A, depending on the mass of water filled in the shoe, the effective centrifuge radius r and the centrifuge speed U. In this case, the water pressure acting on the effective shoe surface by centrifugation is: P = (m · v ² ) / (A · r) = (m · ω ² · r) / A where ω = 2πf v = 2rπf The waterproof test suitable for the invention uses an effective centrifuge radius of 50 cm and a centrifuge speed of 254 rp. If the shoe size is 42 and the effective shoe area is 232 cm 2, the shoe is filled with 1 liter of water. As a result, m = 1 kg v = 2 · 0.5 m · π · 4.23 / s = 13.3 m / s P = (1 kg · (13.3 m / s) ² ) / (0.5 m · 0.0232 m ² ) = 353.8 N / 0.0232 m ² = 0.13956 bar In other shoe sizes with correspondingly different effective shoe surfaces, the water volume can be reduced accordingly to achieve an equal test pressure.

For example, leather or a fibrous flat formed body is suitable as the upper material of the upper. The fibrous sheet formation is, for example, a woven fabric, a knitted fabric, a knit, a fleece or a felt. These fibrous sheet formations are made of natural fibers such as cotton or viscose,
It can be made from synthetic fibers such as polyester, polyamide, polypropylene or polyolefin, or a mixture of at least two of these materials. The midsole of the shoe according to the invention can consist of viscose, fleece, for example polyester fleece in which molten fibers can be incorporated, leather or bonded leather fibres. The midsole is marketed by Texon Mock-Mul (Germany, Germany) under the trade name Texon Midsole.

A backing material is usually arranged inside the outer material of the upper. The same materials listed above for the facings are suitable for this. After sealing according to the invention, the outsole is attached to the sock side. The outsole can be made of a waterproof material, for example rubber or plastic, for example polyurethane, or a non-waterproof material, especially leather. The adhesion between the reactive hot melt adhesive and the sock side is particularly tight when the reactive hot melt adhesive is applied to the sock side and then mechanically pressed against the sock side. A pressing device, preferably formed as a pressure pad, is suitable for this. It is not wetted by the reactive hot melt adhesive,
Therefore, it has a smooth material surface that does not adhere to the reactive hot melt adhesive,
For example, it consists of non-porous polytetrafluoroethene (known under the trade name Teflon). The pressure pad used for this purpose, such as a rubber pad or air pad, is preferably provided with a pressing surface coated with a foil of the abovementioned material, for example a non-porous polytetrafluoroethylene, or with a reactive molten fiber before the pressing process. Such a foil is arranged between the bottom structure provided with the pressure pad.

A material suitable for the functional layer having waterproofness and moisture permeability is described, for example, in US Pat.
As described in U.S. Pat. No. 25418 and U.S. Pat. No. 4,493,870, in particular polyurethanes, polypropylenes, polyesters and polyetheresters and their laminates. However, particularly preferred are, for example, the publication US-A3953
Microporous expanded polytetrafluoroethylene (ePTFE) and expanded polytetrafluoroethylene with moisture permeable impregnants and / or layers as described in US Pat. For this, see, for example, publication US Pat. No. 4,194,041. The microporous functional layer means a functional layer having an average pore size of 0.2 μm to 0.3 μm. The pore size can be measured with a Coulter Porometer (trade name) manufactured by Coulter Electronics (Hiales, Florida, USA). The Coulter porometer is a measuring device that provides an automatic measurement of the pore size distribution of a porous medium and uses a liquid displacement method (described in ASTM standard E1298-89).

A coulter porometer defines the pore size distribution of a subject by increasing the air pressure toward the subject and measuring the resulting flow. The pore size distribution is a measure of the degree of pore uniformity in the subject (ie, a narrow pore size distribution means that the difference between the minimum and maximum pore sizes is small). This pore size distribution is determined by dividing the maximum pore size by the minimum pore size. The Coulter porometer also calculates the pore size for average flow. By definition, half of the flow through the porous subject is through a hole having a pore size above or below the pore size for this average flow. The use of ePTFE as the functional layer allows the reactive hot melt adhesive to enter the pores of this functional layer during the bonding process, so that the reactive hot melt adhesive mechanically settles into this functional layer. The functional layer made of ePTFE may comprise a thin polyurethane layer on the side that comes into contact with the reactive hot melt adhesive during the bonding process. The use of a PU-reactive hot melt adhesive in combination with such a functional layer not only provides a mechanical bond, but also the chemical reaction between the PU-reactive hot melt adhesive and the PU layer on the functional layer. Bonding also occurs. This leads to a particularly tight connection between the functional layer and the reactive hot melt adhesive, so that a particularly lasting waterproofing is ensured. A waterproof outsole and / or a waterproof midsole can be used to achieve waterproofing even in the bottom area. However, if it is also desired to maintain respiratory activity in the bottom area, despite being waterproof, the insole and outsole, at least in part of the area, made of a waterproof and breathable material can be used, and the water in the insole and / or outsole is The waterproof area can be ensured by providing the waterproof / moisture permeable bottom functional layer in the passage area. In a particularly preferred embodiment, the insole is made of a water-permeable material, and the outsole is made of leather on the inside of a peripheral portion made of rubber or plastic, and has a waterproof and moisture-permeable bottom functional layer on the side facing the insole. Is arranged. The bottom functional layer extends toward the bottom periphery so as to overlap at least with the region surrounded by the reactive hot melt adhesive in the fishing section.

The shoe according to the present invention can be composed of a top cover and a functional upper layer covering the inside thereof, and the functional upper layer has at least one backing layer facing the functional layer and the inside of the shoe. Conveniently it is part of the laminate that has. The laminate may have more than one layer, and the fiber back may be on the side of the functional layer away from the backing.
In this case, a fishing portion is formed on both the top cover and the functional layer top.
The bonding of the two fishing portions is performed in only one fishing process or two independent fishing processes, and a reactive hot melt adhesive is used as the bonding portion adhesive.

When two independent fishing steps are carried out for the bonding of the upper cover and the bonding of the functional layer upper, these two lifting steps and the subsequent outsole bonding step are performed in the following manner. It can be implemented within such a time frame. That is, the reactive hot-melt adhesive applied for the first fishing-in process in time is not yet sufficiently advanced in the crosslinking or curing process, and the reactive hot-melt adhesive applied as the outsole is still used. Can also be chemically bonded together to form a waterproof adhesive enclosure for both hooks together. However, these different bonding processes are also carried out in time apart, such that the subsequent bonding takes place only after a partial or complete crosslinking reaction of the hot melt adhesive applied in the previous bonding. You can also. In this case, a mechanical bonding of the hot melt adhesive applied in the different bonding processes takes place, resulting in a similarly waterproof adhesive enclosure.

In another embodiment of the present invention, a facing laminate including a functional upper layer is used.
It is only necessary to cover the inside of the thus configured top cover with a simple backing. In this case, sealing is performed by surrounding the surface laminate including the upper layer with the reactive hot melt adhesive. A gap is created between the midsole and the outsole inside the fishing section, and this gap can be filled with the filler as usual. In the shoe according to the invention, the filler can be any one of the known conventional fillers. However, the gap can also be filled with a reactive hot melt adhesive. Reactive hot-melt adhesive used as an adhesive for fishing part
It is advantageous to inject, for example in the form of a bead, at a predetermined corner formed between the lower peripheral edge of the midsole and the upper part hanging above the midsole edge. Preferably, a reactive hot melt adhesive acting as an outsole adhesive is sprayed below the fishing section.

If the reactive hot melt adhesive is blended with a thermoplastic component, and the resulting adhesive has a rapid and sufficient temporary adhesion based on the blended thermoplastic hot melt adhesive, First, apply an adhesive that acts as an adhesive for the fishing section, and the temporary adhesive force temporarily fixes the fishing section to the midsole, and then applies an outsole adhesive to the underside of the fishing section, and then removes the outsole. Due to the temporary adhesive action of the thermoplastic, it is fixed below the fishing line. The cross-linking reaction that leads to curing under the influence of moisture or water vapor in the air and the thermal activation preceding the cross-linking reaction when using a blocked reactive hot-melt adhesive are each one common It can be performed in the process. Thermoplastics are materials that become tacky by heating and harden by subsequent cooling. The thermoplastic can again be brought into an adhesive state by heating again. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The drawings are only schematic representations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION The shoe according to the first embodiment of the present invention shown in FIG. 1 has an insole 1 and a hook 2 connected to the insole 1 by means of an adhesive. And a reactive hot-melt adhesive 3 applied to the lower side of the insole 1 and the fishing section 2. In this case, the reactive hot-melt adhesive 3 covers the entire area that is not covered by the lower inner bottom fishing section 2, and the partial area of the lower fishing floor 2 adjacent to this area. In a preferred embodiment, the overlap 3a of the reactive hot melt adhesive 3 on the catch 2 is about 1 cm wide. Such shoes are preferably manufactured as follows. First, the insole 1 is fixed to a lower side of a last (not shown). Next, an upper cover is put on the last, and a conventional fishing part is provided on the peripheral part on the lower side of the insole, and the fishing part 2 is put on the lower side of the insole and adhered thereto. Thereafter, a reactive hot melt adhesive 3 is applied to the lower side of the insole 1 and the lower portion 2 and pressed to obtain a sock side having a flat and uniform surface.

This manufacturing state is shown in the side view of FIG. Next, an outsole (not shown) is attached to the sock side provided with the reactive hot melt adhesive 3 by, for example, adhesion. The reactive hot melt adhesive 3 makes the sock side or the bottom structure waterproof. The second embodiment of the invention shown in FIG. 3 differs from the shoe shown in FIGS. 1 and 2 in that the lower surface facing away from the insole 1 has an open-celled, easily adherent material. 4
, Which are bonded in the same plane within the reactive hot melt adhesive 3. By attaching this material 4, the waiting time is reduced and the shoes made up to that point can be processed immediately and immediately.

FIG. 4 shows a side view corresponding to FIG. 2 of the shoe of the second embodiment. Here, it can be clearly seen that the material 4 is adhered so as to extend on the same plane as the reactive hot melt adhesive 3. The reactive hot-melt adhesive 3 is preferably applied as a viscous adhesive, and the consistency can be adjusted by the heating strength of the reactive hot-melt adhesive 3. FIG. 5 shows very schematically a pressing device 5 for pressing the reactive hot-melt adhesive 3 against the insole 1 and the underside of the fishing line 2. A pressure pad of the type described above is particularly suitable for this.

A third embodiment of the shoe according to the present invention will be described with reference to FIGS. These figures show such shoes very schematically in various stages of production.

The shoe according to the third embodiment has a waterproof midsole 11 attached to a last 13. The midsole 11 is inside the upper 15. The upper 15 is made of a water-permeable surface material 17, for example, leather or fiber material. The inside of the surface material 17 is covered with a functional layer laminate 19. The functional layer laminate 19 has an upper functional layer 21, which will be described in detail below in connection with FIG. At this stage of manufacture, the upper 15 has already been stretched over the last 13 and the midsole 11 and the bottom end region of the upper, which later forms the catch, still forms the lower midsole 23. Hanging over. A corner is formed between the peripheral region of the lower midsole 23 and the bottom end region of the upper 15, into which a reactive hot-melt adhesive acting as the glue adhesive 25 is charged. However, this is not necessary for the function of the bonding according to the invention. What is important is that the reactive hot melt type adhesive is applied and
The only difference is that a continuous adhesive strip is formed in the inner bottom peripheral direction between the portion and the portion where the functional layer laminate 19 is fitted. In this case, the adhesive strip can extend over the entire width of the squeezed portion of the functional layer laminate 19 or only part of the width of the squeezed portion of the functional layer laminate 19. Preferably, the tacking adhesive is applied such that it is located in the area of the tacking area connected to the midsole periphery after the tacking process. This area is usually free of wrinkles. The closing wrinkles occur at a certain distance from the peripheral edge of the insole, for example, 5 to 10 mm, particularly at a place where the shoe contour is strongly curved.

In a viscous state that has not yet reacted, there is a sufficient creeping ability, and when a glue portion adhesive is used that can enter sufficiently between the glue wrinkles and seals the glue wrinkles, the glue wrinkles may not be formed. It may be limited so that the adhesive for the hook-in portion is provided only in the width region of the hook-in portion that can occur. In this case, the fishing line adhesive 25 is preferably applied in a paste form using, for example, an adhesive nozzle (not shown) that extrudes an adhesive bead. The triangle of the dip glue 25 is schematically illustrated in FIG. The adhesive bead can have any other cross-section. FIG. 7 shows the part (turned 90 °) of the upper structure after preparation for the fishing glue. In FIG. 2, a portion of the leather serving as the outer material 17 can be seen outside the upper part located on the lower side. In FIG. 2 there is a functional layer laminate 19 inside the upper, which is located on the upper side. The functional layer laminate 19 includes an upper functional layer 21 made of ePTFE as a functional layer material. Outside the upper functional layer 21 facing the facing 17, there is a fiber back surface 27 in the form of a knitted or woven fabric, which mechanically protects the upper functional layer 21. On the inside away from the front material 17, the upper functional layer 21 has a PU layer 29. The upper functional layer 21 with the PU layer 29 can be manufactured according to the teaching of US Pat. No. 5,026,591 (Hen), but is not limited thereto. There is an auxiliary layer 31 inside. This may be, for example, a nonwoven layer 31, a plastic foam layer, a fleece layer or a leather layer. Inside the auxiliary layer 31, there is a fiber closing layer 33. Functional layer laminates 19 of the type shown in FIG. 2 are known per se. In a normal functional layer laminate, the auxiliary layer 31 is too thick for the adhesive to penetrate or to penetrate sufficiently. In order to allow the anchoring adhesive 25 to penetrate to the upper functional layer 21, a reactive hot melt adhesive acting as the anchor adhesive 25 and the upper functional layer 21 or its PU layer 29 (if present) It is known per se that the auxiliary layer 31 and the fiber closing layer 33 are scraped off in the region where the non-woven fabric layer or the foam layer is to be bonded in the region where the bonding is to be performed. In the case of the auxiliary layer 31 formed as leather, the leather layer can be removed from the upper layer 21 in the area to be bonded.

The leather sharpening process can be performed using a leather sharpening machine known in shoe making, for example, Fortuna S4 from Fortuna (Germany). Referring again to FIG. 6, the upper functional layer 21 and the back surface 27 are connected to the fishing line adhesive 25.
The nonwoven fabric 31 and the fiber closure layer 33 terminate almost at the lower midsole 23 following the sharpening shown in FIG. In the region hanging down below the midsole lower side 23, the upper functional layer 21 with the PU layer 29 is exposed, so that a direct adhesive contact with the anchoring adhesive 25 can be entered. In the manufacturing stage shown in FIG. 8, the hooked portion 35 of the upper 15 is wound around the last 13 and the insole 11. In such a fishing stage, the beaded fishing-line adhesive 25 is formed on the flat fishing-line adhesive layer 37. The dimensions of the beads of the fishing line adhesive 25 applied in the manufacturing stage shown in FIG. 1 are set so that the fishing line adhesive layer 37 extends beyond the inner fishing line end face 39 toward the center of the midsole. As best seen in FIG. 3, the cutting edge 36 facing the center of the midsole and its end region 41 facing the lower midsole 23 are surrounded by the glue glue.

The shoe structure shown in FIG. 8 only has an outsole for completion, and the outsole can be attached to the midsole and the fishing part from below. By using the waterproof fishing part adhesive, the water that has traveled along the surface of the upper part to the end on the outsole side of the fishing part 35 is not covered by the lower part of the insole 11. The inside of the layer 21 cannot be reached, and therefore cannot be inside the shoe. Modifications of the third embodiment of the present invention will be described with reference to FIGS. 9 to 11, and the production starts at the production stage shown in FIGS.

Subsequent to the manufacturing steps shown in FIGS. 6 to 8, a reactive hot-melt type adhesive acting as an outsole adhesive 45 is applied to the lower portion 43 of the fishing section. This application is performed so that not only the lower part 43 of the fishing part but also the area of the lower middle part 23 where the bonding part adhesive is not applied as shown in FIG. As shown in FIG. 5, the central region of the lower mid-sole 23 may not be covered with the outsole adhesive. When attaching an outsole which does not have waterproofness itself, the modification shown in FIG. 10 is recommended. The variation shown in FIG. 9 can be selected when attaching a waterproof outsole having waterproofness by itself. If this is the case, in this case, as a result of the waterproof adhesive enclosure 47 on the one hand and the waterproof adhesion of the outsole to the adhesive enclosure 47 on the other hand, water will reach this central region of the lower midsole 23. This is because they cannot enter. This fabrication stage is shown in FIG. In this figure, a reactive hot-melt adhesive forming the hook-up adhesive layer 37 and a reactive hot-melt adhesive for the hook-up portion 43 forming the outsole adhesive 45 include an adhesive enclosure 47. Which acts on the fishing portion 43 like a waterproof jacket.

As shown in FIG. 10, a filler 49 is injected into a gap where no adhesive is applied inside the fishing section 43, and the outsole of the shoe structure manufactured up to this stage is different from the shoe structure manufactured up to this stage. It forms a substantially flat lower side for attaching 51. As a filler, a fleece, for example a PES fleece, a knit, a bottom material, etc., can be used. In the embodiment of the shoe according to the invention shown in FIG. 10, the applied outsole 51 is made of rubber or plastic and the area facing the filler 49 is provided with an air chamber 53. These air chambers save the material of the outsole and also lighten the outsole and thus the entire shoe, and also allow the shoe to land more flexibly on the ground.

With reference to FIG. 11, the sealing action of the adhesive enclosure 47 will be described schematically. A small circle, a water drop, and an arrow schematically indicate the direction of entry and the direction of creeping of the water inside the permeable surface material 17 that allows the creeping of water. The water that has entered the surface material from the outside descends in the upper shell 15 in the longitudinal direction of the surface material 17, and extends along the fishing portion along the fishing surface end surface 39.
Continue to. Such water is impeded by the waterproof fishing line adhesive and cannot enter the interior of the shoe through the fiber material inside the upper layer 21. For the case where the shoe has an outsole with a permeable insole and / or an air chamber 53 opening towards the insole, an adhesive enclosure 47 of the fishing line 35 is provided. Without such an adhesive enclosure, water entering through the facing 17 would be able to travel to the air chamber 53. This is not hindered by the filler 49. This is because the filler 49 is usually made of a water-permeable material. Water entering the air chamber 53 will collect there and will cause crackling, increased shoe weight and cooling of the midsole, thus making the shoe uncomfortable. However, as a result of the sealing adhesive enclosure 47, water is
To the interior of the shoe and / or into the air chamber 53.

The fourth embodiment of the shoe according to the invention shown in FIG. 12 has a shoe structure that is substantially identical to the embodiment of the shoe structure shown in FIG. To that extent, the shoe structure shown in FIG. 12 will not be described again. The shoe structure shown in FIG. 12 has a water-permeable and moisture-permeable midsole 57 made of a nonwoven fabric such as a fleece, for example, and has a waterproof and moisture-permeable outsole 59 shown in FIG. Different from structure. Based on this shoe structure, the shoe shown in FIG. 12 is waterproof and breathes even in the sole area. As a result, shoes with particularly good comfort can be obtained. In the embodiment shown in FIG. 12, the outsole 59 has an outsole marginal area 61 made of rubber or plastic, and the central area of the outsole marginal area 61 is made of a water-permeable and moisture-permeable material, such as leather. Filled with insert 63. On the side facing the midsole 57, on the outsole insert 63 is a waterproof and moisture-permeable bottom functional layer 65, also preferably made of ePTFE. As schematically shown in FIG.
The outer peripheral portion extends toward the peripheral edge of the bottom, so that the adhesive surrounding body 47 and the bottom functional layer 65 overlap. Therefore, water does not penetrate the filler 35 and therefore the inner bottom 57, neither into the fishing line 35 nor through the bottom insert 63. This completely protects the interior of the shoe against the ingress of water, while maintaining respiratory activity in all areas of the shoe. When an outsole made entirely of a water-permeable material is used, the bottom functional layer 65 can extend to the outer periphery of the outsole. The bottom functional layer 65 can be formed of the same material as the upper functional layer, for example, ePTFE, PU, polypropylene or polyester.

FIGS. 13 to 16 show a fifth embodiment of the shoe according to the invention in various stages of manufacture. In this embodiment, a surface laminate 67 that includes both a leather or fiber surface and a functional upper layer is used. The inside of the surface material laminate 67 is covered with a back skin 69 having no functional layer. Since the back skin 69 does not need to be sealed,
In the representation of FIG. 13, the bead-shaped hook-up adhesive 25 is located in the corner between the lower midsole 23 and the inside of the facing laminate 67, since it is cut almost to the lower midsole 23. Otherwise, the shoe structure shown in FIG. 13 is equivalent to the shoe structure shown in FIG.
Here, it will not be described again.

FIG. 14 shows the shoe structure of FIG. 13 according to the manufacturing stage shown in FIG. In this case, as shown in FIG. 15, a reactive hot-melt adhesive is applied as the bottom adhesive 25 on the lower part 43 of the hooking part and the lower part 23 of the midsole, and is preferably sprayed again. The reactive hot melt adhesive applied as the fishing adhesive 25 and the reactive hot melt adhesive applied as the outsole adhesive 45 are recombined to form an adhesive enclosure 47 for sealing the fishing section 35. . As shown in FIG. 16, a filler 49 is then injected into the gap remaining inside the end surface 39 of the fishing part, and a bottom 51 made of rubber or another type of plastic is provided below the fishing part lower part 43 and the filler 49. Attach. Filler 49 can also be formed of outsole material. In the shoe structure shown in FIG. 16, the insole 11 is again made of a waterproof material. However, FIG.
Similar to the second embodiment shown in FIG. 7, in the third embodiment, the waterproof midsole and the breathable waterproof outsole can be combined again. FIG. 17 schematically shows, in a greatly enlarged manner, a part of the bottom structure having a hook-in adhesive 37 formed as a reactive hot melt adhesive in which the reaction has been completed by three-dimensional crosslinking of molecular chains. I have. The three-dimensional nature of the cross-linking is such that the molecular chains of the reactive hot melt adhesive cross-link as shown for the two dimensions even in the third dimension (perpendicular to the plane shown) not visible in FIG. As a result, intrusion of water into the adhesive is particularly strongly prevented.
