Description

Waterproof shoes

The invention relates to a shoe according to the general part of claim 1 and to a process for making it according to the general part of claim 27.

There is a waterproof, but permeable, water-permeable microporous membrane material, which has been increasingly used in the last years to produce waterproof garments. Its permeability to steam gives favorable wear properties. Such membrane material consists e.g. of drawn polytetrafluoroethylene (commonly and hereinafter abbreviated as PTFE), of polyester or of a microporous polyurethane layer.

Recently, such membrane material has also been used to make waterproof shoes. In this case, at least the upper part of the shoe on the inside is coated with such a membrane material, which in the present connection is preferably designated as a functional layer. An example is shown in EP-A2-0 080 710. In general, the lining is formed by a laminate-shaped lining comprising a functional layer and a textile layer facing the inside of the shoe.

The seams created by sewing the upper part of the shoe with the lining and, if available, the insole are problematic. At the peripheral sites, the functional layer is punctured and permeable to water. To avoid this problem, they have already used socks between the upper part and the tread or the sole. insides on the one hand and between the inner liner on the other. Because this sock insert can be molded by welding, it does not have to be sewn into the hole. However, this process is really time-consuming if the socks are to be properly adjusted to each shoe's shape.

Another known procedure is to spray the underside of the upper part of the shoe or. the insole and the lower region of the upper portion, which is coated with a functional layer and optionally sewn with the insole, with a sole made of rubber or plastic, which generally forms the tread. In this case, the seam between the upper part and the lining, and optionally the insole, is closed with a sole made of rubber or plastic, that is, of waterproof material.

It should be noted here that, in the context of the present connection, the term synthetic sole is used as an abbreviation and should include natural or artificial rubber.

The upper part usually consists of leather or fabric e.g. made of man-made fibers.

The injected plastic outsole otherwise seals the seam between the functional layer and the upper part, and in this case the insides against direct water intrusion.

The upper materials mentioned above have the property that they allow water to flow during their longitudinal stretching, which is particularly pronounced in leather upper parts. Capillary effects are involved in this water leakage. Therefore, when the area of the uppermost part not covered by the plastic sole gets wet, water penetrates on the basis of this longitudinal permeability effect along the upper part to the seam, which is inside the injected plastic sole, where it can then penetrate through the holes of the seam. function layer. Typically, the functional layer is located inside the laminate, which is coated with a protective fabric on the side facing the top, and with the backing material facing the outside. With conventional mass production of shoes, it is also barely possible to avoid water bridges at the lower end of the upper part and the lining at economical costs. These may be formed by threads projecting from the cut off portion of the substrate and extending beyond the cut off end of the functional layer to the material of the upper part. In particular, if the upper material consists of a fabric, there is a risk that the upper end and the end of the lining are not cut exactly to the same height, so that neither the textile parts of the upper lengthen the cut end of the functional layer and form a moisture bridge to the lining of the shoe. The lining material of the functional layer on the inside of the shoe is usually absorbent and water-permeable. Along the upper part, the water penetrating and through the seam and / or the said water bridges, the water entering it then penetrates along the lining to the inside of the shoe. According to experience, it lasts only 10 minutes after wetting the outside

sides of the shoe to wet the inside lining.

DE-GM 1 680 553 describes an attempt to achieve better water sealing in shoes without a waterproof and water-permeable functional layer. The shoe described in this specimen comprises a sole frame which, extending in the circumference of the shoe, is formed by the circumferential portion of the insole and the tightly circumscribed circumferential regions of the material of the upper part. In the area of this sole frame, the upper material is also sewn with the insole.

With the help of this seam, a test strip is sewn in the area of the sole frame to the upper side of the upper material. The purpose of this textile band is to provide a better holding rigidity of the plastic sole, which is injected onto the insole and the sole frame. Because the upper side of the upper material often consists of a material on which the plastic sole is only poorly sealed, so that water can penetrate between the outer side of the upper portion and the poorly held plastic sole. With textile straps, it can be achieved that the plastic sole is better adhered to the upper side of the sole frame. However, no improvement is achieved with respect to the penetration of water into the upper material based on the aforementioned capillary effects. In contrast, water-tight textile material facilitates water penetration. If the shoe known from the said file were coated with a waterproof, water vapor-permeable functional layer, which would then be normally protected in the area of the lining of the sole between the upper material and the insole, it would not be possible to prevent

- 5 ...........

water bridges through the threads or textile parts of the material of the upper part and / or the inner lining which lays the functional layer, which can bridge the severed ends of the functional layer. By contrast, the use of textile straps to better hold the material of the plastic sole increases the likelihood of such water bridges being caused by threads or textile pieces. The result is that, when injecting the plastic sole, the liquid material of the plastic sole can penetrate to some extent into the holes of the seam of the sole frame. The chances of the plastic sole penetrating so deep into the seam holes that it even penetrates through the seams of the seam - unforeseen function layers - in the above file, have become smaller, on the basis of covering the upper material with the textile tape, than without such textile tape. The danger of water penetrating downward from the material of the upper part and, when it overcomes the holes of the seam of the functional layer, reaches the inner lining of the shoe, is thus higher than without the use of textile tape.

The invention is based on the task of helping here and the shoe, in which the upper part of the suture is connected to the lining and, optionally, to the insole and a waterproof sole is injected, with the lowest additional cost better sealing the area against water ingress and this intrusion prevent the water inside the shoe from crossing over water bridges as far as possible.

The solution to this problem lies in the shoe according to claim 1, which may be preferably distributed according to claims 2 to 26. For the manufacture of such shoe, the process according to claim 27 or 28, which may be preferably distributed according to claims 29 and 30, is particularly suitable.

By virtue of the invention that the lower region of the upper part adjacent to the tread is porous (which should, in the present dependence, comprise perforated, porous, hole and foam material), the liquid material of the plastic sole may be sprayed on the upper part and if necessary, the insole reaches the functional layer through the lower area of the upper part. to the functional layer of the enclosing laminate. This ensures that the injection molded plastic sole seals the seam holes of the connecting seam between the insole, the functional layer and the upper part, and optionally the insole.

In a particularly preferred embodiment, a laminate having a good permeability to the liquid sole material of the plastic should be included in the functional layer (this term should depend on the present dependency. This will prevent the impermeable parts of the upper part from covering the seams and facilitating or preventing the access of the solids of the plastic sole to the suture holes.Thus, when injecting the plastic soles, pressures are applied in the area of 5 at, with the material of the upper part with relatively high pressure being pressed against the functional layer.

Thus, it is possible to either perforate the upper part material either in the lower, insole and seam adjacent area, or to leave the upper part above the connective seam of the substrate and in this case leave the insole and bridge the gap between the lower end of the upper part and the location of the seam with a punched hole. material. In this case, the hole material of one end of the suture is sewn with the lower end of the subject material of the upper part without being sutured with the functional layer at this point. The puncture material of the other end is firmly adhered to the insole together with the functional layer. This also completely avoids rear water bridges, which may have existed to a lesser extent through the remaining upper material at the upper perforated material in the lower region.

In the latter solution, the hole material may at the same time be designed as a retainer, e.g. as a net of artificial fibers with loopholes in the range of at least 1.5 mm. If the mesh does not have excellent self-adhesive strength, it can be adhesive-based and therefore extremely durable.

If the hole material of the upper part is designed as a net, single net threads should be used. When using multiple filaments, there is a risk that water permeable capillaries may form between the filaments. While the capillaries of a single-strand mesh seal when the liquid material is injected, the capillaries remain between the multiple filaments without sealing and may lead to water even after the material of the plastic material is injected.

The bulbous area of the upper portion may extend beyond the upper edge of the injection molded plastic sole, with either the upper material up to this height being perforated or the outer surface of the injection molding. the holey material that forms the lower end of the upper part extends beyond the upper edge of the artificial sole

substances. This achieves the water drainage function. If water in the upper region of the upper portion reaches between the upper portion and the functional layer, e.g. since the shoe-holder runs through the water, this water can drain through the hole area of the upper part, which lies above the plastic sole. In order to retain the possibility of water leakage in this area of the sole, it is also possible to perforate the area of the sole made of plastic, which is located above the suture of the functional layer and in the case of the insole, preferably extending to the upper edge of the sole. The advantage of this is that the water can be drained through the material of the sole of the sealed seam of the functional layer and, optionally, the insole.

A further advantage is that both the upper material and the sole of the plastic are perforated in the area above the suture of the functional layer and, in the present case, the insole. This leads to an optimum water drainage function that enters the material of the upper part and between the upper part and the functional layer. By using a retainer between the lower area of the upper part and the functional layer, it is also achieved that the material is made of plastic in the intermediate space between the upper part and the functional layer or. The laminate liner rises extremely high, preferably to the upper edge of the plastic injection molded sole. This virtually eliminates the possibility that the possible grooves of cracks in the sole material of the plastic would form channels to guide moisture to the seam location.

The invention is equally suitable for shoes with intermediate soles, for shoes without intermediate soles and for shoes in

- 9 - · '........

according to the Iblypintch process with the intermediate sole designed only in the front of the shoe.

In the case of a shoe with a continuously extending sole, the lower end areas of the upper part and the lining containing the functional layer are firmly sewn on the outer perimeter of the insole, the end areas of the upper part and the soles being directed perpendicularly to the longitudinally extending plane of the insole. The sole of the plastic is injected from the bottom on the insole and from the bottom and laterally in the lower areas of the upper part. In the case of a non-insulated shoe manufactured by the String-Lasting procedure, "the lower ends of the lining containing the upper part and the function layer are held together with guide pins in which a drawstring is guided to perform the String-Lasting process." In this case, the lining and the upper part may be secured to each other by means of guide loops and / or by a seam away from the guide loops. For the manufacture of the Shoe by this method, the lower end of the upper part is lined with a hole or perforated area of the upper part and a lining with a hoof attached thereto, and the lower part of the hoove by means of a drawstring, which runs through the guiding loops together around the hoof. There is a separator on the underside of the hoof that prevents the adhesive material of the plastic sole on the underside of the hoof.

The running sole now splashes on the hoof or bottom. to an area of the upper portion which partially overlaps the underside of the hoof so that it covers the lower portion on the sides of the hoof of the abutting area of the upper portion.

'With these shoes, a water bridge is removed from the subject part of the upper part via the end of the upper part, which is designed by means of a hole-shaped part of the upper part, which represents the connection between the upper part of the upper part and the upper part, which is designed with guide hinges. pins, side to inner lining. With this type of shoe, the danger of a water bridge overcoming the functional layer is particularly high, since the guide hinges are usually made of water-conducting threads and could form such water bridges if there were no hole material of the upper part. The present invention is also suitable for shoes manufactured by the '' Polypintch '' process. Only the front, approximately to the central vault, extending part of the shoe is designed with an intermediate sole, while the rest of the shoe does not include any intermediate sole. In the area of the intermediate sole, the lower region of the upper part and the sewn lining are sewn around the lower edge of the intermediate sole. In the area without the intermediate sole, the lower areas of the upper part are thus sewn to the perpendicular to the plane of the tread. At least in the area without the intermediate sole, the hoof is again designed with a separating agent which prevents the liquid material of the plastic sole from adhering to the hoof. For the manufacture of the tread, the liquid material is made of plastic from the bottom to the intermediate sole. The hoof is sprayed so that the plastic material also covers the sides of the upper part to a certain height. Also, the hole material of the upper portion at the lower end of the upper portion prevents the formation of a water bridge from the object material of the upper portion around the functional layer to the substrate.

The invention will now be explained in more detail based on embodiments. Schematic representations of the shoe show: FIG. 1 shoe of known type;

Polypintch, from below;

FIG. 7 is a cross-section along the cross-section line 1-1 of FIG. 6; and FIG. 8 is a cross-section along the cross-section 2-2 of FIG. 6.

According to FIG. 1 comprises a shoe of a known type, upper part S, preferably consisting of leather or fabric, preferably plastic. The inner side of the upper part S is coated with laminate L, which takes on the function of the inner lining and comprises a watertight and water-permeable functional layer or membrane M, which is coated with fabric T on the upper part of S facing and on the inside of the shoe facing the inside. with a backing material F. The backing material F and the fabric T form a mechanical protection of the functional layer M. At its lower end, the connection from the upper part S and the laminate L is sewn with the edge of the insole B and the seam is marked N. The underside of the insole B and s this sewn lower region of the upper portion S is injected with the sole K of any suitable waterproof plastic. The upper edge 0 of the sole K lies so high that the seam N is surrounded by the sole K. The seam is thus sealed against the direct appearance of water. Water that appears on the outside of the sole K lying down, but along the upper part on the inside of the sole K can reach the seam, penetrate through the holes of the seam in the functional layer M and reach the inside of the shoe.

There is also a risk that when cutting the upper material and the substrate L, which comprises at least one textile layer, the remaining threads or parts of the fabric, which, bypassing the functional layer F of the substrate L, form a connection between the upper part and the substrate F. If the upper part water and water from there to the end of the upper part, water can then reach these through the water bridges from there to the base material F, so that the base material F becomes wet.

This is prevented in the following embodiments of the invention.

In the embodiment shown in FIG. 2, the upper portion S comprises, in the region of the interior connection, the hole portion P of the upper portion. When injecting the sole K, liquid rubber or plastic passes through the openings of the hole area P of the upper part onto the laminate. The material of the plastic sole, which is then placed between the laminate L and the upper part S, seals the holes of the seam in the functional layer M. The water that reaches the material of the upper part under the seam N cannot penetrate the seams of the seals which are closed with the material. plastic sole. This prevents water from entering the shoe.

The left side of FIG. 2 shows a modified embodiment in which between the perforated region P is the upper part and

- 13 - .......

laminate L Inserted punched or punched hole retainer A. This holds the laminate L and the hole area P of the upper part at a distance from each other and when injecting the sole K, the liquid material of the plastic sole may penetrate through. Due to the retainer holder, more plastic sole material can reach between the upper part and the laminate. In addition, when using the retainer A, the injected plastic material may rise to a higher area between the upper part and the laminate L than would be possible without the retainer A. Therefore, due to the high injection pressure when injecting the sole K, the sealing nozzle of the injection tool in the area of the upper edge 0 of the sole K must be pressed against the upper part with a correspondingly high pressure. Without the retainer A, only the corresponding plastic material could reach between the upper part S and the laminate L. More material in this interstitial space increases the likelihood that the channels of cracks in the plastic material will not become wet channels.

The retainer A may extend beyond the upper edge 0 of the sole K. It is possible to even cover the entire upper portion S with the retainer, which gives the shoe greater overall stability and may allow simpler manufacturing processes.

The preferred materials for the K sole are polyurethane (PU), polyvinyl chloride (PVC) and transparent rubber (TR).

The retainer A of the cam may be sewn, on the one hand, and on the other hand, which is permeable to the liquid material of the plastic material during injection. The preferred material is man-made filaments with mesh size of at least 1.5 mm.

The recoil holder A should preferably be made of single-stranded material in order to avoid fibrous channels which can conduct water and which cannot be sealed with the plastic material when injected and which occur in the multifilament material. As an artificial fiber material, it is suitable e.g. polyamide and polyester. The material of the retainer A may be coated with adhesive to increase its rigidity and strength

In the embodiment of the invention shown in FIG. 3, the upper part S does not extend to the insole B, but has a lower end upper part offset from the insole edge. This offset is bridged with punctured or porous bonding material V, which may be the same material as the offset holder A. The upper edge of the binding material V is sewn tightly at the lower edge of the upper part S at the seam N1. However, laminate L is not sewn to the top at this point. The other end of the bonding material V is sewn together with the lower end of the laminate L with the insole, at the seam N2.

When injecting the sole K, the liquid material reaches the sole through the pores or holes or loops of the bonding material V to the outside of the laminate L, thus sealing the gray holes of the N2 seam with the sole.

By forming the lower area of the upper portion with a punctured or porous binder material V mounted on the upper object above, the guided water cannot reach the area of the seam connecting the upper part, the liner and the interior from the object upper, so that water bridges, formed by threads or pieces of textile with which the seam and the functional layer are bridged cannot be effective because the water in the upper part cannot reach them.

FIG. 4 and 5 show the embodiment of the shoe according to the invention, which is made by the String-Lasting ”process. Herein, FIG. 4 shows a cross-sectional view, while FIG. 5 shows a bottom view before applying the plastic sole K. In this manufacturing process, the punctured or porous bonding material V is sewn firmly at the lower end of the upper portion by means of a N1 suture. The bonding material V and the liner L containing the functional layer are sewn together at their free end, preferably by means of FS guide loops. ZS's drawstring runs through the lead loops. Prior to injection of the plastic sole K, the upper part S and the liner L are positioned around the hoof, and then the lower end region of the upper part S and the liner L are fastened together by means of a drawstring ZS until the entire upper part S with the liner L with which it is lined , it basically doesn't fit on the hoof. The plastic sole K is then injected from below, with the underside of the hoof formed by a separating means. After removal of the hoof, the lower area of the lining F and the intermediate region of the lining K of plastic are lined with lining.

Even in this embodiment, it would be possible between the bonding material V and the liner F, as shown on the left side of FIG. 2, Insert retainer A.

FIG. 6 to 8 show the use of the invention in a shoe manufactured by the Polypintch process. FIG. 6 shows a view of such a shoe from below before injection of a plastic sole. FIG. 7 and 8 show cross-sections through this shoe along the 1-1, respectively, cross-sections. 2-2, of course after injection of the plastic sole.

In the area of insole B extending from the front end of the shoe to the central arch of the foot, the lower area of the upper part S and the lining L are bent around the lower edge of the insole B. In the rear area of the shoe that does not include the insole, the lower ends of the upper part S and the lining L oriented perpendicular to the plane of the tread. In the area of insole B, the bonding material V, with which the upper material is extended, is located below the insole. In the non-insect area, the bonding material V is located in the lower lateral region of the upper S. The plastic sole is injected into the insole region to the underside of the insole and the upper folded area below the insole and in the area outside the insole to the hoof which is designed with a separating agent. After removing the shoe from the hoof, the shoe is lined with a shoe.

For Polypintch shoes with a watertight, water vapor-permeable functional layer, there is a problem that, in normal manufacturing processes, it is hardly possible to cut the upper material at the dividing point between the insole and the non-insole area as precisely as possible. , - that the textile material of the upper part or the textile material of the lining or fibers does not protrude or. projected over the severed end of the function layer and formed there. formed a water bridge. Since the lower end region of the upper part is formed by the bonding material V, which is mounted on the upper part S, the water conduction line formed by the material of the upper upper part S cannot continue to the cut end of the substrate and thus function. layers, so that there are no water bridges that exist by themselves, through seam holes and threads, and pieces of textile that bridge the cut end of the functional layer.
