Description

Die Erfindung betrifft ein Schuhwerk, welches zumindest ein Teil eines Schuhs ist, bestehend aus einem Schaft, der zumindest eine Außenschicht und ein die Außenschicht von innen auskleidendes, eine wasserdichte und wasserdampfdurchlässige Funktionsschicht enthaltendes Futter aufweist, einer ersten, den Innenbereich des Schuhwerks nach unten abschließenden Brandsohle, einer zweiten Brandsohle und einer an die zweite Brandsohle angeklebten Laufsohle, wobei der untere Endbereich des Futters nach innen umgeschlagen und auf der zweiten Brandsohle angeordnet und mit dieser wasserdicht verbunden ist, und wobei die zweite Brandsohle eine umlaufende Außenkante aufweist, die Außenkante eine der Kontur des unteren Endbereichs der Außenschicht entsprechende Kontur aufweist und und mit dem unteren Endbereich der Außenschicht verbunden ist.The invention relates to footwear, which at least one Is part of a shoe, consisting of a shaft that at least an outer layer and the outer layer from the inside lining, a waterproof and water vapor permeable Has lining containing functional layer, a first closing the inside of the footwear down Insole, a second insole and one to the second Insole glued to outsole, with the lower end of the feed turned inside and on the second Insole arranged and connected to this waterproof is, and wherein the second insole is a circumferential Has outer edge, the outer edge one of the contour of the lower End region of the outer layer has a corresponding contour and and with the lower end portion of the outer layer connected is.

Ein derartiges Schuhwerk in klebegezwickter Ausführungsform ist aus DE-OS 40 07 962 bekannt. Bei dem dort beschriebenen Schuhwerk wird vorausgesetzt, daß die zweite Brandsohle selbst dadurch wasserdicht ausgebildet ist, daß sie zur Futterseite hin ebenfalls eine wasserdichte und wasserdampfdurchlässige Schicht aufweist, und daß die Futterschicht zur Außenschicht hin die wasserdichte wasserdampfdurchlässige Funktionsschicht aufweist. Eine Anwendung der bekannten Konstruktion auf andere Macharten, wie beispielsweise gestrobeltem Schuhwerk (Schuhwerk, bei dem die zweite Brandsohle mit der Außenschicht mit einer Nähmaschine der Firma Strobel vernäht ist) oder Schuhwerk in Flexbauart (Außenschicht wird im unteren Bereich nach außen umgeschlagen und mit einer Brandsohle im Umschlagsbereich vernäht), ist praktisch nicht möglich,Such footwear in a sticky embodiment is known from DE-OS 40 07 962. With the one described there Footwear is assumed to be the second insole itself is designed to be watertight in that it is on the lining side also a waterproof and water vapor permeable Has layer, and that the lining layer for The outer layer towards the waterproof water vapor permeable Has functional layer. An application of the well-known construction to other designs, such as strobed Footwear (footwear in which the second insole with the outer layer using a sewing machine from the company Strobel is sewn) or flexible footwear (outer layer is turned outwards in the lower area and sewn with an insole in the envelope area) is practical not possible,

Bei der in DE-OS 40 07 962 beschriebenen Ausführungsform kann beim Verkleben der zweiten Brandsohle mit der Funktionsschicht des Futters nicht sichergestellt werden, daß über den Kleber über die gesamte Fläche eine wasserdichte Verbindung zwischen Futter und zweiter Brandsohle hergestellt wird. Insofern kann ohne weiteres Wasser zwischen das Futter und die zweite Brandsohle eindringen. Außerdem wird die Funktionsschicht beim Gebrauch des Schuhwerks stark belastet, was häufig zur Rißbildung in der Funktionsschicht oder zum Aufbrechen des Klebers im Verbindungsbereich zwischen Funktionsschicht und zweiter Brandsohle führt, wodurch Wasser ungehindert ins Innere des Schuhs eindringen kann.In the embodiment described in DE-OS 40 07 962 can when gluing the second insole to the functional layer of the feed can not be ensured that the Glue a waterproof connection over the entire surface is produced between the lining and the second insole. To that extent can easily between the feed and the water penetrate second insole. In addition, the functional layer heavily burdened when using the footwear what often for crack formation in the functional layer or for breaking open of the adhesive in the connection area between the functional layer and second insole leads, which allows water to flow freely can penetrate inside the shoe.

Um die wasserdichte wasserdampfdurchlässige Funktionsschicht vor zu großer mechanischer Belastung zu schützen, ist man dazu übergegangen, diese Funktionsschicht von außen mit einem textilen Material zu verstärken. Für derartige Funktionsschichten ist eine wasserdichte Verbindung zwischen Funktionsschicht und der zweiten Brandsohle fast nicht mehr möglich, weil nicht sichergestellt werden kann, daß der Kleber das textile Verstärkungsmaterial, welches nunmehr zwischen der Funktionsschicht und der zweiten Brandsohle angeordnet ist, vollständig durchdringt. Insofern werden bereits bei der Herstellung des Schuhwerks Kanäle gebildet, durch welche wiederum Wasser in den Innenbereich des Schuhwerks eindringen kann. Selbst wenn größere Kanäle noch vermieden werden können, ergeben sich im Verbindungsbereich zwischen Futter und zweiter Brandsohle Mikrokanäle, die sich infolge ihrer Kapillarkräfte mit Wasser vollsaugen.To the waterproof, water vapor permeable functional layer One is to protect against excessive mechanical stress proceeded to this functional layer from the outside with a reinforce textile material. For such functional layers is a watertight connection between the functional layer and the second insole almost no longer possible, because it cannot be guaranteed that the adhesive the textile reinforcement material, which is now between the functional layer and the second insole is completely permeated. In this respect, the Manufacture of footwear formed through which channels again water penetrate into the inside of the footwear can. Even if larger channels can still be avoided, arise in the connection area between feed and second insole microchannels, which result from their capillary forces soak up with water.

Insofern ist man bei der Herstellung von atmungsaktivem, jedoch wasserdichten Schuhwerk, welches eine wasserdichte wasserdampfdurchlässige Funktionsschicht enthält, immer mehr dazu übergegangen, eine angespritzte Laufsohle einzusetzen, da beim Anspritzen des Laufsohlenmaterials scheinbar geringere Probleme hinsichtlich Wasserdichtigkeit auftreten. Außerdem ist diese Machart kostengünstig herzustellen.In this respect, one is in the manufacture of breathable, however waterproof footwear, which is a waterproof water vapor permeable functional layer contains more and more started to use a molded outsole, since apparently less when the outsole material is molded on Problems with water resistance occur. This design is also inexpensive to manufacture.

Aufgabe der vorliegenden Erfindung ist es, ein Schuhwerk der eingangs genannten Art mit angeklebter Laufsohle zur Verfügung zu stellen, welches zumindest verbesserte Eigenschaften hinsichtlich Wasserdichtigkeit gegenüber dem bisher bekannten Schuhwerk mit angeklebter Sohle aufweist. Es ist weiterhin Aufgabe der vorliegenden Erfindung, ein Schuhwerk mit angeklebter Laufsohle zur Verfügung zu stellen, welches unabhängig von der Machart verbesserte Wasserdichtigkeit gewährleistet.The object of the present invention is to provide footwear type mentioned at the beginning with glued outsole available to ask what at least improved properties in terms of water resistance compared to the previously known Footwear with glued sole. It is still Object of the present invention, a footwear with glued To provide outsole which is independent The design ensures improved water resistance.

Diese Aufgabe wird bei einem Schuhwerk, welches zumindest einen Teil eines Schuhs umfaßt, bestehend aus einem Schaft, der zumindest eine Außenschicht und ein die Außenschicht von innen auskleidendes, eine wasserdichte und wasserdampfdurchlässige Funktionsschicht enthaltendes Futter aufweist, einer ersten, den Innenbereich des Schuhwerks nach unten abschließenden Brandsohle, einer zweiten Brandsohle und einer an die zweite Brandsohle angeklebten Laufsohle, wobei der untere Endbereich des Futters nach innen umgeschlagen und auf der zweiten Brandsohle angeordnet und mit dieser wasserdicht verbunden ist, und wobei die zweite Brandsohle eine umlaufende Außenkante aufweist, die Außenkante der zweiten Brandsohle eine der Kontur des unteren Endbereichs der Außenschicht entsprechende Kontur aufweist und mit dem unteren Endbereich der Außenschicht verbunden ist, dadurch gelöst, daß die zweite Brandsohle derart ausgeschnitten ist, daß sie eine umlaufende Innenkante aufweist und somit einen Streifen zwischen Außenkante und Innenkante bildet, daß das Futter nach unten um einen unteren Endbereich länger ausgebildet ist als die Außenschicht, daß der untere umgeschlagene Endbereich des Futters einen ersten Teilabschnitt, der auf der zweiten Brandsohle aufliegt, und einen zweiten Teilabschnitt aufweist, der die Innenkante der zweiten Brandsohle nach innen überragt, und daß zumindest der zweite Teilabschnitt des unteren umgeschlagenen Endbereichs des Futters mit der ersten Brandsohle wasserdicht verbunden ist.This task is in a footwear, which at least comprises part of a shoe, consisting of a shaft, the at least one outer layer and the the outer layer of inside lining, a waterproof and water vapor permeable Has lining containing functional layer, one first, closing the inside of the footwear down Insole, a second insole and one to the second insole glued to outsole, the lower one End area of the lining turned over and on the second insole and waterproof with it is connected, and wherein the second insole is a has circumferential outer edge, the outer edge of the second Insole one of the contour of the lower end of the Outer layer has the appropriate contour and with the lower End area of the outer layer is connected, solved in that the second insole is cut out such that it has a circumferential inner edge has and thus a strip between the outer edge and Inner edge forms the lining down around a lower one End region is longer than the outer layer that the lower folded end of the lining a first Section that rests on the second insole, and has a second section, which the inner edge of the second insole protrudes inwards, and that at least the second section of the lower folded end region of the lining with the first insole waterproof is.

Durch das Ausschneiden der Brandsohle und das Überstehen des zweiten Teilabschnitts des unteren umgeschlagenen Endbereichs des Futters wird es möglich, nunmehr die wasserdichte Verbindung, die mit der ersten Brandsohle erfolgt, zu kontrollieren. Hierbei erfolgt die wasserdichte Verbindung zwischen dem ersten Teilabschnitt des unteren umgeschlagenen Endbereichs des Futters mit der zweiten Brandsohle bevorzugt über einen Kleber.By cutting out the insole and protruding from the second section of the lower folded end region of the feed it becomes possible now the watertight connection, with the first insole. The waterproof connection between the first section of the lower folded end region of the lining with the second insole preferably over an adhesive.

Das erfindungsgemäße Schuhwerk zeichnet sich insbesondere dadurch aus, daß die wasserdichte Verbindung des zweiten Teilabschnitts des unteren umgeschlagenen Endbereichs des Futters mit der ersten Brandsohle über eine von der Laufsohlenseite her aufgebrachte Dichtmasse erfolgt ist.The footwear according to the invention is characterized in particular by this from that the waterproof connection of the second Section of the lower folded end of the Lining with the first insole over one from the outsole side applied sealing compound is done.

Selbst, wenn bei Einsatz eines textilen Verstärkungsmaterials auf der Funktionsschicht das textile Verstärkungsmaterial nicht vollständig mit Kleber durchtränkt werden kann, ist dennoch eine wasserdichte Verbindung zwischen erster Brandsohle und Funktionsschicht möglich, weil nunmehr über die Innenkante (Schnittkante) die Funktionsschicht, die in der Regel zwischen zwei textilen Flächengebilde laminiert ist, bei der Herstellung des Schuhwerks frei zugänglich ist und diese Innenkante nunmehr leicht und vollständig mit Dichtmasse beschichtet werden kann, wobei diese Dichtmasse gleichzeitig die Verbindung zur ersten Brandsohle bildet. Da nunmehr an der Schnittkante des Futters ein guter Kontakt auch mit der zwischen zwei textilen Flächengebilden angeordneten Funktionsschicht erreicht werden kann, da ja die Schnittkante nicht mit diesen textilen Flächengebilden abgedeckt ist, wird auf einfache Weise eine dichte Verbindung zwischen Funktionsschicht und erster Brandsohle erreicht.Even if a textile reinforcement material is used the textile reinforcement material on the functional layer cannot be completely soaked with adhesive nevertheless a watertight connection between the first insole and functional layer possible because now over the inner edge (Cut edge) the functional layer that is in the Is usually laminated between two textile fabrics, is freely accessible in the manufacture of the footwear and this inner edge now easily and completely with sealing compound can be coated, this sealing compound at the same time forms the connection to the first insole. There now make good contact at the cut edge of the feed also with the arranged between two textile fabrics Functional layer can be achieved, since yes Cutting edge not covered with these textile fabrics is a tight connection in a simple way achieved between the functional layer and the first insole.

Dabei hat es sich besonders bewährt, wenn die Dichtmasse ein Kleber ist. Hierzu eignen sich die für die Herstellung von Schuhen üblicherweise verwendeten Kleber vorzüglich. Diese zeichnen sich durch gute Festigkeitseigenschaften aus, sodaß ein Überstreichen des Übergangs vom zweitem Teilabschnitt des unteren umgeschlagenen Endbereichs des Futters zur ersten Brandsohle mit dem Kleber praktisch ausreicht, um eine wasserdichte Verbindung ausreichender Festigkeit zwischen der wasserdichten wasserdampfdurchlässigen Funktionsschicht und der ersten Brandsohle zu erreichen. Gegebenenfalls kann die Festigkeit der Kleberschicht durch Zugabe von Fäden, insbesondere von textilen Flächengebilden wie Vliesen, Geweben oder Gewirken, verbessert werden, wobei die Fäden oder textilen Flächengebilde bevorzugt aus Monofilamenten bestehen.It has proven particularly useful if the sealant Is glue. The are suitable for the production of Shoes commonly used glue excellent. This are characterized by good strength properties, so a sweep of the transition from the second section of the lower folded end of the lining to the first Insole with the glue is practically enough to get one watertight connection of sufficient strength between the waterproof water vapor permeable functional layer and to reach the first insole. If necessary, the Strength of the adhesive layer by adding threads, in particular of textile fabrics such as fleeces, fabrics or knitted fabrics can be improved, the threads or textile Flat structures preferably consist of monofilaments.

Um die Festigkeit der wasserdichten Verbindung des zweiten Teilabschnitts des unteren umgeschlagenen Endbereichs des Futters mit der ersten Brandsohle zu erhöhen, hat es sich auch bewährt, wenn diese Verbindung über einen von der Laufsohlenseite her aufgebrachten Klebebandstreifen erfolgt ist. Klebebandstreifen, die mit einem Schmelzkleber, beispielsweise auf Polyurethanbasis, beschichtet sind, sind hierzu bestens geeignet. Diese lassen sich auf einfache Weise auf die dafür vorgesehenen Stellen aufbügeln.To the strength of the waterproof connection of the second Section of the lower folded end of the It increased to increase lining with the first insole also proven when this connection is made from the outsole side adhesive tape has been applied. Adhesive tape strips with a hot melt adhesive, for example on a polyurethane basis, are coated best for. These can be opened easily iron the designated areas.

Bei dem erfindungsgemäßen Schuhwerk ist es ausreichend, wenn die erste Brandsohle innerhalb des umgeschlagenen Endbereichs des Futters angeordnet ist und mit dem umgeschlagenen Endbereich des Futters eine gemeinsame Ebene aufweist, und daß ein zwischen dem umgeschlagenen Endbereich des Futters und der Außenkante der ersten Brandsohle vorhandener Spalt von der Dichtmasse ausgefüllt und überdeckt ist. Beim Aufbringen der Dichtmasse dringt die Dichtmasse in den Spalt zwischen Futter und erster Brandsohle, sodaß auch hier gewährleistet ist, daß die Schnittkante des umgeschlagenen Endbereichs des Futters und die Außenkante der Brandsohle sicher in die Dichtmasse eingebettet ist, sodaß eine gute Abdichtung erfolgt. Zur Erhöhung der Festigkeit der den Spalt ausfüllenden und überdeckenden Dichtmasse hat es sich als besonders günstig herausgestellt, wenn die erste Brandsohle mit dem zweiten Teilabschnitt des unteren Endbereichs des Futters, bevorzugt mit einer Strobelnaht, vernäht ist. Auch bei dieser Naht ist die Verwendung von Monofilamenten zu empfehlen.With the footwear according to the invention it is sufficient if the first insole within the folded end area of the lining is arranged and with the folded end area of the feed has a common level, and that a between the folded end area of the feed and the Outer edge of the first insole existing gap from the Sealant is filled and covered. When applying the Sealant penetrates the sealant into the gap between the feed and first insole, so that here too it is guaranteed that the cut edge of the folded end of the feed and the outer edge of the insole securely into the sealant is embedded so that there is a good seal. To increase the strength of the gap filling and covering Sealing compound has proven to be particularly cheap, if the first insole with the second section the lower end of the feed, preferably with a strobe seam is sewn. With this seam too Recommended to use monofilaments.

Als besonders vorteilhaft hat es sich herausgestellt, wenn bei dem erfindungsgemäßen Schuhwerk die erste Brandsohle auf dem umgeschlagenen Endbereich des Futters aufliegt und den ersten und den zweiten Teilabschnitt überdeckt. Hierdurch kann die Dichtigkeit zwischen Brandsohle und Futter besonders einfach über die Dichtmasse gewährleistet werden.It has proven to be particularly advantageous if the first insole in the footwear according to the invention the folded end area of the feed and the covers the first and the second section. Hereby the tightness between insole and lining can be particularly can easily be guaranteed via the sealing compound.

Es ist günstig, wenn zwischen der ersten Brandsohle und der Laufsohle eine den Zwischenraum zwischen erster Brandsohle und Laufsohle ausfüllende Ausballschicht angeordnet ist, die eine Außenkante aufweist, welche innerhalb der Innenkante der zweiten Brandsohle verläuft und den Übergang zwischen zweitem Teilabschnitt des unteren umgeschlagenen Endbereichs des Futters zur ersten Brandsohle abdeckt. Diese Ausballschicht kann in einfacher Weise aus demselben Material hergestellt sein wie die erste bzw. die zweite Brandsohle. Die Ausballschicht ist jedoch bevorzugt aus einem wasserdichten Kunststoffmaterial hergestellt.It is beneficial if between the first insole and the Outsole the space between the first insole and outsole filling ball layer is arranged, the has an outer edge which within the inner edge of the second insole runs and the transition between the second Section of the lower folded end of the Lining for the first insole. This ball out can easily be made from the same material be like the first or the second insole. The ball-out layer but is preferably made of a waterproof plastic material manufactured.

Hierbei hat es sich als Vorteil herausgestellt, wenn die Ausballschicht mit dem zweiten Teilabschnitt des unteren umgeschlagenen Endbereichs des Futters und/oder mit der ersten Brandsohle wasserdicht verbunden ist. Somit trägt die Ausballschicht nicht nur zur Verbesserung des Komfort des Trägers sondern auch zur Erhöhung der Dichtigkeit bei, da sie die dichte Verbindung zwischen zweitem Teilbereich des unteren umgeschlagenen Endbereichs des Futters und der ersten Brandsohle unterstützt und, im dem Falle, bei dem die Ausballschicht mit dem zweiten Teilabschnitt und der ersten Brandsohle verbunden ist, auch mit zur Festigkeit der Verbindungsstelle beiträgt.It has proven to be an advantage here if the Ball layer with the second section of the bottom folded over End area of the feed and / or with the first Insole is connected waterproof. Thus, the Ball layer not only to improve the comfort of the Wearer but also to increase the tightness since they the tight connection between the second section of the lower one turned over end area of the feed and the first Insole supports and, in the case where the ball layer with the second section and the first Insole is also connected to the strength of the joint contributes.

Auch hierbei hat es sich bestens bewährt, wenn die wasserdichte Verbindung zwischen dem zweiten Teilabschnitt des unteren umgeschlagenen Endbereichs des Futters beziehungsweise der ersten Brandsohle und der Ausballschicht über Verkleben erfolgt ist.Here, too, it has proven its worth if the waterproof Connection between the second section of the lower folded end area of the feed respectively the first insole and the ball layer over gluing is done.

Zur Stabilisierung der Außenform der Außenschicht kann es bei dem erfindungsgemäßen Schuhwerk von Vorteil sein, wenn zumindest im Gelenkbereich die nebeneinanderliegenden Abschnitte des Streifens der zweiten Brandsohle über eine Halterung miteinander verbunden sind. Dies kann im einfachsten Falle über Fäden, insbesondere Monofilamente erfolgen. Die Halterung kann aber auch ein Gewebe, ein Gewirke oder ein Vlies sein. Auch hier hat sich der Einsatz von Monofilamenten bestens bewährt. Die Halterung sollt bevorzugt derart ausgebildet sein, daß im Falle einer Verklebung der Laufsohle mit der ersten Brandsohle, gegenenfalls über die Ausballschicht, der die Laufsohle verbindende Kleber gut die Halterung durchdringen kann. Offene Gewebe oder Gewirke haben sich insofern bestens bewährt.It can help to stabilize the outer shape of the outer layer the footwear according to the invention may be advantageous if at least the adjacent sections in the joint area the strip of the second insole over one Bracket are connected. The easiest way to do this Traps are made using threads, especially monofilaments. The holder can also be a woven, a knitted or a Be fleece. Here too, the use of monofilaments well proven. The holder should preferably be designed in this way be that in the case of gluing the outsole with the first insole, if necessary over the ball layer, the glue connecting the outsole is good for the bracket can penetrate. In this respect, open fabrics or knitted fabrics have well proven.

Das erfindungsgemäße Schuhwerk läßt sich sowohl für klebegezwickte Schuhe als auch für Schuhe, bei denen die zweite Brandsohle an die Außenschicht angenäht (angestrobelt) ist, einsetzen. Besonders bewährt hat sich jedoch das erfindungsgemäße Schuhwerk für Schuhe in Flexbauart, bei denen der untere Endbereich der Außenschicht nach außen umgeschlagen ist, und der umgeschlagene Teil der Außenschicht zumindest in etwa parallel zur Erstreckungsrichtung der Laufsohle angeordnet und mit der zweiten Brandsohle vernäht ist. Diese Schuhe zeichnen sich durch hohen Tragekomfort aus, weil sie sich hinsichtlich Abrollen besonders flexibel verhalten. Die als bequem geltenden Schuhe hatten jedoch bisher den Ruf, nicht besonders dicht zu sein. Durch das erfindungsgemäße Schuhwerk wird jedoch dieser Nachteil wirksam geringer, in den meisten Fällen sogar vollständig vermieden.The footwear according to the invention can be used for both sticky people Shoes as well as shoes where the second Insole is sewn onto the outer layer (strobed), deploy. However, the invention has proven particularly useful Footwear for flex-type shoes, in which the lower End region of the outer layer has turned over to the outside, and the folded part of the outer layer at least approximately arranged parallel to the direction of extension of the outsole and is sewn to the second insole. These shoes are characterized by high wearing comfort because they stand out behave particularly flexibly with regard to rolling. As Comfortable shoes, however, have so far not had a reputation to be particularly dense. Through the footwear according to the invention however, this disadvantage is effectively reduced in most Cases even completely avoided.

Das erfindungsgemäße Schuhwerk wird anhand der nachfolgenden Figuren näher erläutert.The footwear according to the invention is based on the following Figures explained in more detail.

In den Figuren ist der Schaft aus einer Außenschicht 1 und einem die Außenschicht von innen auskleidendem Futter 2 gebildet. Das Futter 2 besteht aus dem eigentlichen Futterstoff und einer wasserdampfdurchlässigen wasserdichten Funktionsschicht (nicht dargestellt). Gegebenenfalls kann die Funktionsschicht auf der der Futterschicht abgewandten Seite noch eine weitere textile Schicht aufweisen. Üblicherweise sind die textilen Schichten auf die Funktionsschicht zumindest punktweise aufgeklebt, weshalb das gesamte Futter 2 als Laminat bezeichnet werden kann.In the figures, the shaft is made of an outer layer 1 and a lining 2 lining the outer layer from the inside. The lining 2 consists of the actual lining material and a water vapor permeable waterproof functional layer (not shown). If necessary, the functional layer on the side facing away from the lining layer have another textile layer. Usually are the textile layers on the functional layer at least glued on at points, which is why the entire lining 2 as Laminate can be called.

Im dargestellten Fall handelt es sich um ein Schuhwerk in Flexbauweise. Hierzu ist der untere Endbereich 1' der Außenschicht 1 nach außen umgeschlagen, erstreckt sich in Richtung des Sohlenmaterials und liegt in paralleler Anordnung auf der zweiten Brandsohle 4 auf und ist über die Naht 5 mit dieser vernäht. Das Futter gemäß Figur 1 und 3 ist in seinem unteren Endbereich nach innen und um eine erste Brandsohle 3 umgeschlagen. Ein erster Teilabschnitt 2' des unteren Endbereichs des Futters 2 liegt auf der zweiten Brandsohle 4 auf und ist mit der zweiten Brandsohle 4 wasserdicht verklebt, welche derart ausgeschnitten ist, daß sie einen in sich geschlossenen Streifen bildet, wie deutlich in Figur 2 zu sehen ist. Ein zweiter Teilabschnitt 2'' des unteren Endbereichs des Futters überlappt den Bereich 4' der zweiten Brandsohle 4 und endet in der Innenkante oder Schnittkante 2"'. Der zweite Teilabschnitt 2'' ist über die Dichtmasse 7 mit der ersten Brandsohle 3 wasserdicht verbunden, wobei die Dichtmasse die Schnittkante 2''' sicher umfaßt. Der Übersichtlichkeit halber ist die Dichtmasse 7 in Figur 2 nicht dargestellt. An die zweite Brandsohle 4 ist eine Laufsohle 6 angeklebt, die in Figur 2 nicht dargestellt ist, um besser den Innenaufbau des Schuhwerks darstellen zu können.In the case shown, it is a footwear in Flex construction. For this purpose, the lower end region 1 'of the outer layer 1 turned outward, extends in the direction of the sole material and lies in a parallel arrangement on the second insole 4 and is over the seam 5 with this sewn. The feed according to Figures 1 and 3 is in its lower End area turned inwards and around a first insole 3. A first section 2 'of the lower end region of the lining 2 rests on the second insole 4 and is glued waterproof to the second insole 4, which is cut out so that it is a self-contained Stripes form, as can be clearly seen in Figure 2. A second section 2 '' of the lower end region of the Lining overlaps the area 4 'of the second insole 4 and ends in the inner edge or cut edge 2 "'. The second Section 2 ″ is with the first via the sealing compound 7 Insole 3 connected waterproof, the sealant Cutting edge 2 '' 'securely embraced. For the sake of clarity the sealant 7 is not shown in Figure 2. To the second insole 4 is glued to an outsole 6, which in Figure 2 is not shown to better the internal structure of the To be able to represent footwear.

In Figur 3 ist zusätzlich eine Ausballschicht 9 dargestellt, die mit dem unteren Teilabschnitt 2'' des unteren Endbereichs des Futters verklebt ist. Die Ausballschicht 9 kann auch mit der ersten Brandsohle 3 im Innenbereich, also in dem Bereich, der nicht vom untern Endbereich des Futters 2 überdeckt ist, verklebt sein.FIG. 3 also shows a ball-out layer 9, with the lower section 2 '' of the lower end region of the feed is glued. The Ausballschicht 9 can also the first insole 3 in the interior, that is in the area which is not covered by the lower end area of the lining 2, be glued.

In Figur 2 ist zusätzlich ersichtlich, das der untere Endbereich des Futters 2 im Spitzen- und im Fersenbereich eingeschnitten und mit einer Naht 8 vernäht ist, um Faltenbildung in diesem Bereich zu vermeiden. Günstigerweise wird die Naht 8 mit einem Klebeband abgedichtet. Sofern an anderer Stelle im unteren Endbereich (erster und zweiter Teilabschnitt 2' und 2'') des Futters Falten auftreten sollten, kann auch an diesen Stellen das Futter eingeschnitten, vernäht und gegebenenfalls mit einem Klebeband abgedichtet werden.In Figure 2 it can also be seen that the lower end region of the lining 2 cut in the toe and heel area and sewn with a seam 8 to prevent wrinkles to avoid in this area. Conveniently the seam 8 sealed with an adhesive tape. Unless otherwise in the lower end area (first and second subsection 2 ' and 2 '') of the lining wrinkles may also occur these places the feed is cut, sewn and if necessary be sealed with an adhesive tape.

In Figur 4 ist das in Figur 2 dargestellte Schuhwerk im Gelenkbereich durch ein Gitter 10 verstärkt, welches bevorzugt aus Monofilamenten hergestellt ist. Dieses Gitter ist an die zweite Brandsohle 4 im Bereich der Innenkante angenäht. Auf diese einfache Weise kann bei der Herstellung des Schuhwerks die äußere Form des Schuhs stabilisiert werden, ohne daß die Verklebung der Laufsohle auf die zweite Brandsohle behindert wird, da dieses Gitter vom Klebstoff leicht durchdrungen werden kann. Diese Stabilisierung hat sich insbesondere bei gestrobeltem Schuhwerk bestens bewährt.In Figure 4, the footwear shown in Figure 2 is in the joint area reinforced by a grid 10, which is preferred is made from monofilaments. This grid is on the second insole 4 sewn in the area of the inner edge. On this simple way can be used in the manufacture of footwear the outer shape of the shoe can be stabilized without the Bonding of the outsole to the second insole hinders because this grid is slightly penetrated by the adhesive can be. This stabilization has particularly well-tried footwear.

In Figur 5 ist ein weiterer Teilschnitt eines erfindungsgemäßen Schuhwerks dargestellt. Hier ist die erste Brandsohle innerhalb des umgeschlagenen Endbereichs des Futters angeordnet und weist mit dem umgeschlagenen Endbereich (2' und 2'') des Futters 2 eine gemeinsame zur Fußseite hin liegende Ebene auf, sodaß eine innere ebene Fläche gebildet ist. Im Bereich 11 ist die erste Brandsohle 3 an den zweiten Teilabschnitt 2'' des unteren umgeschlagenen Endbereichs des Futters 2 angestrobelt (angenäht). Der Spalt im Bereich 11 ist vollständig mit Dichtmasse ausgefüllt, wobei die Dichtmasse den Spalt von unten überdeckt.In Figure 5 is another partial section of an inventive Footwear shown. Here is the first insole arranged within the folded end region of the feed and points with the folded end region (2 'and 2 '') of the lining 2 a common lying towards the foot side Level on, so that an inner flat surface is formed. in the Area 11 is the first insole 3 on the second section 2 '' of the lower folded end of the lining 2 stroked on. The gap in area 11 is completely filled with sealant, the sealant covered the gap from below.

Obwohl in der Regel der gesamte Schuh aus dem erfindungsgemäßen Schuhwerk hergestellt ist, kann es in Spezialfällen auch vorkommen, daß nur Teile des Schuhs, beispielsweise nur der Spitzenbereich, der Gelenkbereich oder der Fersenbereich aus dem erfindungsgemäßen Schuhwerk gebildet ist und die anderen Bereiche aus einem anderen für diesen Bereich günstigen Schuhwerk besteht. Beispielsweise ist es bei Schutzschuhen mit Stahlkappe zu empfehlen, lediglich den Bereich ohne Stahlkappe gemäß dem erfindungsgemäßen Schuhwerk auszubilden.Although usually the entire shoe from the invention Footwear is made, it can in special cases also happen that only parts of the shoe, for example only the toe area, the joint area or the heel area is formed from the footwear according to the invention and the others Areas from another favorable for this area Footwear exists. For example, it is with protective shoes Recommended with steel cap, only the area without Form steel toe according to the footwear according to the invention.
