Definitions
- the invention relates to footwear with an outsole and a shaft which has a sole end region on the sole which is prestressed towards the center of the outsole at least over part of its circumference.
- footwear styles in which a sole-side shaft end area is stretched over a last in order to be able to carry out further manufacturing steps, for example the attachment of an outsole to the sole-side shaft end area.
- an insole is used, 5, to which the sole end area of the upper is fastened, for example by means of lasting glue, before the outsole is attached to the end area of the sole.
- footwear that is insole-free over at least a portion of its longitudinal extension, with the sole of the shaft end being fixed below the last by so-called string or loading.
- the shaft end area on the sole side is provided with a drawstring which is lashed down by tightening and knotting a cord guided in a cord tunnel below the last. The outsole is then attached to the underside of the lashed shaft end area.
- the cord of conventional cord pulls also has a certain, albeit very low and insufficient elasticity for the purpose according to the invention Restoring force.
- Elastic means according to the invention should have an elasticity and a restoring force which are significantly higher than those of conventional cord pulls which are not designed for elastic pretensioning.
- the aim of the present invention is to create a possibility of being able to finally tighten a shaft part after the shaft has been closed by means of a sole.
- footwear with an outsole and o a shaft which has a sole end region on the sole which is elastically biased towards the center of the outsole at least over part of its circumference by an elastic means.
- the elastic means makes it possible, after closing the shaft with a sole, to tension the shaft end area with the aid of a last inserted in the shaft, as is the case with a conventional cord pull by lashing the cord.
- the invention is particularly advantageous if, after closing the upper with a sole, processing steps are to be carried out in which it would be unfavorable or undesirable to have finally set the upper end region into its tensioned state.
- An example of this is flexibly sewn footwear, in which the upper is provided with an upper material and a waterproof functional layer that at least partially lines the inside of the upper material, and an upper material end region that is angled outwards is sewn to a peripheral edge of a sole. If the functional layer end area on the sole side were already in its final position during the sewing of the upper material end area to the sole biased, there is a risk that the circular needle of the sole sewing machine used for flexibly sewn footwear will perforate the functional layer. As a result, the footwear that is to be waterproofed using the functional layer would leak. 5
- Reactive hot-melt adhesive is particularly suitable for sealing the functional layer in the sole area, which leads to watertightness in the fully reacted state.
- Reactive hot-melt adhesive in which particles which can be heated by radiation absorption, such as carbon or metal particles, are particularly advantageous. This sometimes simplifies the activation heating of the reactive hot melt adhesive.
- the invention can be applied to footwear with or without a functional layer and regardless of the use of adhesive and the type of adhesive 5 used.
- the end region of the shaft material on the sole side is prestressed by the elastic means.
- the end area of the functional layer on the sole side is penetrated biased an elastic means; the sole-side end region of both the upper material and the functional layer are each prestressed by an elastic means.
- an elastic cord is used as the elastic means.
- the elastic cord can have a cord tunnel and an elastic cord arranged therein.
- the elastic cord is arranged to be movable in the cord tunnel in the longitudinal direction of the cord relative to the cord tunnel.
- the elastic cord is fixed to the cord tunnel at predetermined longitudinal intervals.
- the elastic cord pull has an elastic cord which is fixed at predetermined longitudinal intervals on the peripheral edge of the upper material end region or the functional layer end region. The elastic cord can be fixed by sewing.
- the elastic means is in the form of an elastic band in the form of a rubber strand sewn to the functional layer end area, e.g. Rubber band.
- the elastic means is a flat, elastic material, e.g. in the form of a rubber net, which bridges the opening on the sole side of the shaft end region.
- the elastic means is formed in that at least one part of the functional layer insert located in the end region on the sole side is constructed with elastic material.
- This can be an elastic functional layer material and / or an elastic textile material connected to the functional layer material. Is the built up entire functional layer insert with elastic material, it may be advantageous to fix the part of the functional layer insert located between the upper shaft opening and the end area on the sole side to the inside of the upper material by means of an adhesive leading to maintaining breathability or water vapor permeability, for example punctiform adhesive.
- the footwear has a waterproof, water vapor-permeable functional layer.
- the invention makes a functional layer insert available for at least partially lining the upper of the upper of footwear with an outsole, the functional layer insert being open on the sole side and having a functional layer end region on the sole side which is elastically prestressed at least over part of its circumference by an elastic means in the direction of the outsole center is.
- a functional layer is regarded as "watertight", possibly including seams provided on the functional layer if it has a water inlet pressure of at least 1.13. 10 4 Pa guaranteed.
- the functional layer material preferably ensures a water inlet pressure of over 10 5 Pa.
- the water inlet pressure is to be measured according to a test method in which distilled water is applied at 20 ⁇ 2 ° C to a sample of 100 cm 2 of the functional layer with increasing pressure. The pressure rise of the water is 60 ⁇ 1 cm Ws per minute. The water inlet pressure then corresponds the pressure at which water first appears on the other side of the sample. Details of the procedure are given in the ISO standard 0811 from 1981.
- a functional layer is considered to be "water vapor permeable” if it has a water vapor permeability number Ret of less than 150 m -Pa-W- 1 .
- the water vapor permeability is tested according to the Hohenstein skin model. This test method is described in DIN EN 31092 (02/94) and IS0 11092 (19/33).
- Suitable materials for the waterproof, water vapor-permeable functional layer are in particular polyurethane, polypropylene and polyester, including polyether esters and their laminates, as are described in the documents US Pat. No. 4,725,418 and US Pat. No. 4,493,870.
- stretched microporous polytetrafluoroethylene (ePTFE) as described, for example, in the documents US Pat. No. 3,953,566 and US Pat. No. 4,187,390
- stretched polytetrafluoroethylene which is provided with hydrophilic impregnating agents and / or hydrophilic layers, are particularly preferred; see, for example, US-A-4,194,041.
- a microporous functional layer is understood to mean a functional layer whose average pore size is between approximately 0.2 ⁇ m and approximately 0.3 ⁇ m.
- the textile fabrics can be, for example, woven fabrics, knitted fabrics, knitted fabrics, fleece or felt. These textile fabrics can be made from natural fibers, for example from cotton or viscose, from synthetic fibers, for example from polyesters, polyamides, polypropylenes or polyolefins, or from mixtures of at least two such materials.
- a lining material is normally arranged on the inside of the functional layer. The same materials are suitable as lining material, which is often bonded to the functional layer to form a functional layer laminate, as previously indicated for the outer material.
- the upper of the footwear can also be constructed with a laminate that has the upper, the functional layer and the lining.
- the outsole of footwear according to the invention can be made of waterproof material such as e.g. Rubber or plastic, for example polyurethane, consist of or of non-waterproof, but breathable material such as, in particular, leather or leather provided with rubber or plastic inlays.
- waterproof material such as e.g. Rubber or plastic, for example polyurethane
- non-waterproof outsole material the outsole can be made waterproof while maintaining the breathability by providing it with a waterproof, water-vapor-permeable functional layer at least in places where the sole structure has not already been made waterproof by other measures.

- the functional layer end region 17 on the sole side is provided with an elastic means for Center of the opening 15 elastically biased.
- the functional layer insert 11 is stretched 5 away from the center of the opening 15 due to the fact that it is pulled over the strips 13.
- the functional layer end region 17 is tensioned accordingly and the folds 21 are essentially no longer present.
- the elastic means has the form of an elastic pull 19 in the form of a cord pull 39 with a cord tunnel 41 and an elastic cord 43 located therein (FIGS. 3 and 4) or a sewn-on cord Rubber strands (FIG. 5), by means of which the functional layer end region 17 is elastically prestressed.
- the elastic cord 43 is relatively movable in its longitudinal direction within the cord tunnel 41.
- the elastic cord 43 is predetermined

- FIG. 6 shows an embodiment of a functional layer insert 11 according to the invention, in which its opening 15 on the sole side is elastically prestressed by means of a flat, elastically prestressing material in the form of a rubber net 46 which is glued or sewn to the opening edge.
- the elastic means is formed in that at least one part of the functional layer insert 11 located in the end region on the sole side is constructed with elastic material. It can are elastic functional layer material and / or an elastic textile material connected to the functional layer material.
- the elastic means in all 5 previous representations are in the relaxed state, which leads to a contraction of the functional layer end region 17 with the formation of indicated folds 21.
- FIG. 8 shows a first, in a schematic cross-sectional representation approximately at the longitudinal point of the footwear at which the upper shaft opening is located
- Embodiment of footwear 23 according to the invention which can be provided with a functional layer insert 11 according to the invention of one of the embodiments shown in FIGS. 1 to 7.
- the functional layer insert 11 is part of a shaft 25 which is constructed with an upper material 27 and the 5 functional layer insert 11 and is fastened to an outsole 29.
- the functional layer insert 11 is constructed with a functional layer 31 and a lining layer 33 located on the inside of the functional layer 31.
- the functional layer insert 31 is connected to the upper material 27 at an upper shaft end region (not shown) and is glued to the inside of the outsole 29 at its sole-side end region 35 by means of adhesive.
- the adhesive 37 consists of material or has at least a proportion of material which, in the hardened state, leads to the waterproofness of the adhesive 37. 5
- the ends of the functional layer 31 and the lining layer 33 on the sole side are connected, for example sewn, with an elastic cord 39.
- the elastic cord 39 has a cord tunnel 41, in the interior of which an elastic cord 43 is arranged, which prestresses the sole-side end region 35 of the functional layer insert 11 in the direction of the outsole center.
- the elastic cord 23 is either arranged to be movable in the cord longitudinal direction relative to the cord tunnel 41 or fixed to the cord tunnel 41 at 5 predetermined longitudinal distances, for example by sewing.
- the functional layer 31 is waterproof and permeable to water vapor, so that the footwear 23 provided with the functional layer insert 11 is waterproof but nevertheless breathable.
- the adhesive 37 which is watertight in the hardened state, prevents water, which penetrates the generally water-permeable upper material 27, from penetrating on the outside of the functional layer 31 to the elastic cord 39 and entering the lining layer 33, which is made of generally relatively highly absorbent material ,
- the outsole 29 is cup-shaped and has a raised side edge 45, from which an outer edge edge 47 protrudes laterally.
- the upper material has an outer material end region 49 which projects outwards and is sewn to the peripheral edge 27 of the sole by means of a sole seam 51.
- a sole sewing machine with a circular needle is conventionally used to produce such a sole seam 51. If the sole seam 51 were only produced after the functional layer insert 11 has the position shown in FIG. 8, there would be a great risk that the circular needle would perforate the functional layer 31 when sewing the sole seam 51 and thus make it leaky. How this can be prevented by means of a functional layer insert 11 according to the invention is explained with reference to FIGS. 9 to 7, which manufacturing phases show before reaching the state of the footwear 23 shown in FIG. 8, with additional modifications being shown. 5
- the adhesive layer 53 shown in Fig. 9 consists of conventional
- Outsole adhesive for example in the form of solvent adhesive or hot glue, both for example based on polyurethane.
- Neoprene adhesives are also suitable.
- Solvent adhesive is an adhesive that has been made adhesive by the addition of evaporable solvent and hardens due to the evaporation of the solvent.
- Hot glue is an adhesive, also called thermoplastic adhesive, which is brought into an adhesive state by heating and hardens by cooling. Such adhesive can be brought repeatedly into the adhesive state by heating again.
- thermoplastic adhesives for example, polyesters, polyamides and thermoplastic polyurethanes are suitable.
- Such a conventional outsole adhesive leads to rapid bonding between the outsole 29 and the functional layer insert 11, but does not have a sufficiently reliable and permanent sealing effect, particularly at locations where the sole-side end region of the functional layer insert tends to form wrinkles, which is particularly the case at the locations which the circumference of the shoe has a narrow radius of curvature.
- the adhesive layer 55 shown in FIG. 10 is a reactive hot melt adhesive which, in the fully reacted state, leads to watertightness.
- Reactive hot melt adhesives are adhesives that are used before they are activated consist of relatively short molecular chains with an average molecular weight in the range of about 3000 to 5000 g / mol, are non-sticky and, if necessary after thermal activation, can be brought into a reaction state in which the relatively short molecular chains crosslink to form long molecular chains and thereby harden, mainly in a humid atmosphere. During the reaction or curing period, they are adhesive and have a high creeping capacity, so that they also reliably penetrate wrinkles. After curing, they cannot be reactivated. When reacting out, there is a three-dimensional cross-linking of molecular chains. This three-dimensional networking leads to particularly strong protection against the ingress of
- polyurethane reactive hot melt adhesives for example, polyurethane reactive hot melt adhesives, resins, aromatic hydrocarbon resins, aliphatic hydrocarbon resins and condensation resins, for example in the form of epoxy resin (EP), are suitable.
- Polyurethane hot melt adhesives also called PU reactive hot melt adhesives, are particularly preferred.
- Activation temperatures for PU reactive hot melt adhesives are approximately in the range from 70 ° C to 180 ° C.
- PU reactive hot-melt adhesives such as those sold under the name IPATHERM S 14/242 by H.P. Filler in Wells, Austria, or under the name MACROPLAST QR 6202 from Henkel AG, Düsseldorf, Germany.
- FIG. 11 shows a manufacturing phase using the outsole 29 provided with reactive hot-melt adhesive 55 according to FIG. 10, in which the functional layer insert 11 is arranged within the upper material 27 and in which the outwardly angled upper material end region 49 is fixed to the sole peripheral edge 47 by means of fixing adhesive 58.
- the elastic cord 39 is relaxed, which is why the sole-side end region of the functional layer insert 11 is pulled towards the outsole center and away from it Outsole is lifted off.
- the outward angled upper material end region 49 is fixed on the sole peripheral edge 47 by means of the fixing adhesive 58, because the reactive hot melt adhesive 55 has not yet been activated in this production phase.
- pressure-sensitive adhesive 59 is applied to the underside of the end region 35 of the functional layer insert 11, which - as in the case of the fixing adhesive 58 - can be conventional solvent or hot-melt adhesive.
- FIG. 12 A production phase is shown in FIG. 12, in which the outwardly angled upper material end region 49 and the sole peripheral edge 47 are sewn by means of the sole seam 51.
- This sole seam 51 could be sewn without endangering the functional layer 31 because the end region 35 of the functional layer insert 11 on the sole side is removed due to the elastic cord 39 from the effective range of the sewing needle used for sewing the sole seam 51.
- FIG. 12 shows a modification compared to FIG. 11 in that the sole circumferential edge 47 and the inner wall of the sole side edge 45 are not coated with reactive hot-melt adhesive 55 but conventional outsole adhesive 53 and the underside of the sole-side end region 35 of the functional layer insert 11 is not with conventional adhesive but with reactive hot-melt adhesive 61 is provided.
- a last (not shown) is inserted into the interior of the functional layer insert 11 in order to bring the sole-side end region 35 of the functional layer insert 11 into the position shown in FIG. 8, under tension of the elastic cord 39.
- the reactive hot melt adhesive 55 or 61 is activated, preferably by supplying thermal energy, and is thus brought into its adhesive state, the crosslinking reaction being brought about, for example, by the atmospheric humidity.
- the 5 hotmelt adhesive 55 or 61 forms a layer which leads to watertightness.
- conventional adhesive 53 or 59 is also provided in order to achieve a faster adhesive effect than can be achieved with the currently preferred PU reactive hot melt adhesives.

- the structure produced so far is stretched over a last 13, which facilitates mechanical pressing of the upper material end region 49 and the midsole peripheral edge 65.
- the end region 35 of the functional layer insert 11 on the sole side is stretched, but this would not be necessary per se in this manufacturing phase.
- the last 13 is removed from the shaft 25, so that the end region 35 of the functional layer insert 11 on the sole side contracts due to the elastic cord 39 and stands out from the upper material end region 49.
- the sole seam 51 can therefore be sewn without any risk to the functional layer 31 of the functional layer insert 11.
- the footwear is then stretched again over the lasts 13 in order to bring the sole-side end region 35 of the functional layer insert 11 into the position shown in FIG. 15, in which the reactive hot-melt adhesive 61 touches the top of the midsole 63 and can be glued to it.
- the reactive hot-melt adhesive 61 is activated by supplying energy that heats the reactive hot-melt adhesive 61.
