Description

Die Erfindung betrifft einen wasserdichtes Schuhwerk, welches zumindest einen Teil eines Schuhs umfaßt, enthaltend eine Oberschicht (1), ein Futter (2) mit einer wasserundurchlässigen, aber wasserdampfdurchlässigen Funktionsschicht, eine Brandsohle (3) und eine angeklebte Laufsohle.The invention relates to a waterproof footwear, which at least a part of a shoe, comprising an upper layer (1), a lining (2) with a impermeable but water vapor permeable functional layer, a Insole (3) and a glued outsole.

Ein Schuh aus derartigem Schuhwerk ist in der unveröffentlichten deutschen Patentanmeldung, Aktenzeichen 195 13 413.3-26 beschrieben. Dieser Schuh ist in klebegezwickter Ausführungsform hergestellt und dient dazu den Komfort des Trägers des Schuhs zu erhöhen. Bei diesem Schuh wird sowohl das Ankleben von Laufsohlen als auch das Anspritzen von Laufsohlen empfohlen.A shoe made of such footwear is in the unpublished German Patent application, file number 195 13 413.3-26. This shoe is in adhesive-twisted embodiment manufactured and serves the comfort of Increase wearer of the shoe. With this shoe both the sticking of Outsoles as well as the injection of outsoles recommended.

In der Vergangenheit wurde die Entwicklung von wasserdichten Schuhen, deren Komfort durch eine wasserdichte, wasserdampfdurchlässige Funktionsschicht erhöht werden soll, die in der Regel in die Futterschicht integriert ist, hauptsächlich bei Schuhen mit angespritzter Laufsohle betrieben, weil das zur Herstellung der Laufsohlen verwendete Spritzmaterial von unten her schon von sich aus gute Dichtigkeit garantierte und eine gute Verbindung mit dem Obermaterial gestattete.In the past, the development of waterproof shoes, their Comfort increased by a waterproof, water vapor permeable functional layer which is usually integrated into the lining layer, mainly at Shoes with molded outsole operated because of the manufacture of the Outsoles used spray material from the bottom out of their own good Guaranteed tightness and allowed a good connection with the upper material.

Aus EP-A -0 544 270 ist ein Schuh mit angespritzter Laufsohle bekannt, bei dem das untere Ende des Futters nach innen umgeschlagen und parallel zur Laufsohle angeordnet ist. Die Außenkante der Brandsohle ist mit der Endkante des Futters vernäht. An dieses Schuhwerk ist eine Sohle angespritzt. Um die Formhaltung während der Herstellung zu gewährleisten, ist das Futter im unteren Bereich mit der Oberschicht verklebt. Diese Machart läßt sich nicht ohne weiteres auf Schuhe mit angeklebter Sohle übertragen, weil die beim Anbringen der Sohle erforderlichen Kräfte deutlich größer sind als beim Anspritzen einer Laufsohle und somit das Futter besonders stark belastet wird, wodurch die im Futter enthaltene wasserdichte, wasserdampfdurchlässige Funktinsschicht reißen und somit undicht werden kann.From EP-A-0 544 270 a shoe with a molded outsole is known, in which the the lower end of the lining turned inwards and parallel to the outsole is arranged. The outer edge of the insole is with the end edge of the lining sewn. A sole is molded onto this footwear. To keep the shape To ensure during production, the lining is in the lower area with the Glued top layer. This type of construction cannot be easily applied to shoes transferred glued sole because the necessary when attaching the sole Forces are significantly greater than when molding an outsole and thus the lining is particularly heavily loaded, which means that the waterproof, water-vapor-permeable functional layer tear and can therefore leak.

Aufgabe der vorliegenden Erfindung ist es, ein weiteres wasserdichtes Schuhwerk mit angeklebter Laufsohle zur Verfügung zu stellen, welches nicht nur in klebgezwickter Ausführungsform hergestellt ist. Insbesondere ist es Aufgabe der Erfindung, ein Schuhwerk in gestrobelter Machart zur Verfügung zu stellen, welches mit einer angeklebten Laufsohle ausgestattet werden kann.The object of the present invention is a further waterproof footwear to provide with glued outsole, which is not only in adhesive-twisted embodiment is produced. In particular, it is the job of Invention to provide footwear in a strobed design, which can be equipped with a glued-on outsole.

Bei einem wasserdichten Schuhwerk, welches zumindest einen Teil eines Schuhs umfaßt, enthaltend eine Oberschicht, ein Futter mit einer wasserundurchlässigen, aber wasserdampfdurchlässigen Funktionsschicht, eine Brandsohle und eine Laufsohle, wobei das die Funktionsschicht enthaltenden Futtereinen unteren Endbereich aufweist, welcher nach innen umgeschlagen und parallel zur Laufsohle angeordnet ist, wobei der umgeschlagene Endbereich mit der Brandsohle in einer gemeinsamen Ebene liegt und einen inneren Rand aufweist, die Außenkante der Brandsohle zumindest in etwa parallel zu dem inneren Rand des umgeschlagenen Endbereichs verläuft, die Brandsohle mit dem umgeschlagenen Endbereich verbunden ist, wird die erfindungsgemäß gestellte Aufgabe dadurch gelöst, daß die Laufsohle flächig zumindest mit dem umgeschlagenen Endbereich der Funktionsschicht des Futters verklebt ist, daß das untere Ende der Oberschicht im wesentlichen senkrecht zur Laufsohle angeordnet ist und zumindest im Gelenkbereich mit einer parallel zur Laufsohle angeordneten Halterung verbunden ist und/oder zumindest im Spitzenbereich ein Gitter aus Monofilamenten mit dem unteren Ende .der Oberschicht verbunden ist, und daß das Futter innerhalb der Oberschicht lose angeordnet ist.In the case of waterproof footwear, which is at least part of a shoe comprises, comprising a top layer, a lining with a water-impermeable, but water vapor permeable functional layer, an insole and an outsole, the lining containing the functional layer having a lower end region has, which turned over and arranged parallel to the outsole is, the folded end portion with the insole in a common Level lies and has an inner edge, the outer edge of the insole at least approximately parallel to the inner edge of the folded end region runs, the insole is connected to the folded end area the object of the invention achieved in that the outsole is flat at least with the folded end area of the functional layer of the lining is glued that the lower end of the top layer substantially perpendicular to Outsole is arranged and at least in the joint area with a parallel to Outsole arranged holder is connected and / or at least in A lattice made of monofilaments with the lower end .der Upper layer is connected, and that the lining is loose within the upper layer is arranged.

Der untere Endbereich soll, wie ausgeführt, in einer Ebene mit der Brandsohle liegen. Der untere Endbereich des Futters und die Brandsohle sollen also so angeordnet sein, daß sowohl der Endbereich des Futters als auch die Brandsohle flach auf der Laufsohle aufliegen. Dies schließt allerdings nicht aus, daß Brandsohle und unterer Endbereich des Futters sich überlappen können. Es kann aber ohne weiteres zwischen dem inneren Rand des Endbereichs des Futters und der Außenkante der Brandsohle ein Abstand bestehen. Hierbei ist die Brandsohle mit dem umgeschlagenen Endbereich des Futters bevorzugt vernäht (gestrobelt). Beim Strobeln (Vernähen) dieser beiden Teile kann ein Abstand ohne weiteres durch die die Naht bildenden Fäden überbrückt werden.As stated, the lower end area should be in one plane with the insole lie. The lower end of the lining and the insole should be like this be arranged that both the end of the lining and the insole Lie flat on the outsole. However, this does not rule out that insole and the lower end area of the feed can overlap. But it can be done without further between the inner edge of the end portion of the lining and the There is a clearance between the outer edge of the insole. The insole is included preferably the sewn end of the lining sewn (strobed). At the Strobing (sewing) of these two parts can be done easily by the distance the threads forming the seam are bridged.

Für die vorliegende Erfindung wesentlich ist, daß über den zur Verklebung der Laufsohle verwendeten Kleber eine wasserdichte Brücke zwischen Funktionsschicht und Laufsohle erzeugt wird. Dies kann dadurch erreicht werden, daß die Kleberschicht sehr dünn ausgebildet wird, sodaß eine innige Verbindung zwischen Laufsohle und Funktionsschicht erreicht wird. Man kann aber auch eine dickere Klebeschicht verwenden, wobei jedoch dann bevorzugt Kleber verwendet werden, die nach dem Abbinden wasserdicht sind. Polyurethankleber eignen sich hierzu hervorragend.For the present invention, it is essential that the Outsole glue used a waterproof bridge between the functional layer and outsole is produced. This can be achieved in that the Adhesive layer is formed very thin, so that an intimate connection between Outsole and functional layer is achieved. But you can also use a thicker one Use adhesive layer, but then glue is preferably used which are waterproof after setting. Polyurethane adhesives are suitable for this outstanding.

Es ist auch günstig, wenn zumindest im Spitzenbereich ein Gitter aus Monofilamenten mit dem unteren Ende der Oberschicht verbunden, vorzugsweise vernäht ist und somit den Spitzenbereich der Oberschicht in Form hält.It is also advantageous if a grid is formed at least in the tip area Monofilaments connected to the lower end of the top layer, preferably is sewn and thus keeps the tip area of the top layer in shape.

Bei dem erfindungsgemäßen Schuhwerk kann auf eine direkte Verbindung zwischen Futter und Oberschicht, beispielsweise auf ein Ankleben des Futters an die Oberschicht, vollständig verzichtet werden. In anderen Worten: Das Futter ist innerhalb der Oberschicht lose angeordnet bzw. ist lediglich an der Oberkante des Obermaterials, also der von der Sohle abliegenden Kante, die die Öffnung für die Einführung des Fußes darstellt, mit dieser Oberkante verbunden.In the footwear according to the invention, a direct connection between Lining and top layer, for example by sticking the lining to the Upper class, to be completely dispensed with. In other words, the feed is loosely arranged within the top layer or is only on the upper edge of the Upper material, i.e. the edge away from the sole, which is the opening for the Introducing the foot represents connected to this top edge.

Die Formhaltung des Schuhwerks bei der Herstellung kann auch dadurch verbessert werden, daß zumindest im Gelenkbereich ein Gitter aus Monofilamenten mit den unteren Enden der Obeschicht verbunden, vorzugsweise vernäht ist und somit die Oberschicht in Form hält. Das Gitter kann aber auch über den gesamten Fußbereich erstreckt werden, wenn es beispielsweise auf besonders genaue Einhaltung der Form des Schuhwerks ankommt.This can also improve the shape of the footwear during manufacture be that at least in the joint area a grid of monofilaments with the lower ends of the top layer is connected, preferably sewn and thus the Upper class keeps in shape. The grille can also over the entire foot area be extended if, for example, on particularly precise compliance with the Shape of the footwear arrives.

Zur Formhaltung während der Herstellung hat es sich auch als günstig herausgestellt, wenn die Oberschicht im Spitzenbereich nach unten verlängert und nach innen derart umgeschlagen ist, daß der umgeschlagene Teil der Oberschicht parallel zur Laufsohle angeordnet ist. Hierbei ist es günstig, wenn direkt in der Spitze ein Zwickel herausgeschnitten wird und die nunmehr entstandenen Kanten miteinander vernäht werden. Diese Art der Formhaltung ist auch in der noch nicht veröffentlichten deutschen Anmeldung, Aktenzeichen 195 13 412.5 für Schuhe mit angespritzter Sohle beschrieben.For keeping shape during manufacture, it has also proven to be cheap exposed when the top layer in the tip area extends downward and is turned inside so that the turned part of the upper class is arranged parallel to the outsole. It is advantageous if directly in the The tip of a gusset is cut out and the resulting edges are sewn together. This type of shape is not yet in the published German application, file number 195 13 412.5 for shoes with molded sole described.

Auch im Fersenbereich hat es sich als vorteilhaft herausgestellt, wenn die Oberschicht im Fersenbereich nach unten verlängert und nach innen derart umgeschlagen ist, daß der umgeschlagene Teil der Oberschicht parallel zur Laufsohle angeordnet ist. Hierbei hat es sich bewährt, wenn in dem Bereich, in dem die Oberschicht nach innen umgeschlagen ist, die Außenkontur der Brandsohle an der Funktionsschicht anliegt und die Oberschicht mit der Funktionsschicht um die Außenkontur der Brandsohle geschlagen ist.In the heel area, too, it has proven to be advantageous if the Upper layer in the heel area extended downwards and inwards like this is turned over that the turned over part of the upper class parallel to Outsole is arranged. It has proven useful here in the area in which the upper layer is turned inwards, the outer contour of the insole of the functional layer and the upper layer with the functional layer around the Outer contour of the insole is struck.

Die Formhaltung kann auch dadurch gewährleistet werden, daß der untere Endbereich der Oberschicht zu einem Bund geformt ist, indem der untere Endbereich umgeschlagen und mit der Oberschicht verbunden wird, daß in dem Bund eine Kordel eingelegt ist, über welche das untere Ende der Oberschicht gehalten wird. Hierbei hat es sich besonders bewährt, wenn der Bund im Spitzenbereich des Schuhwerks angeordnet ist und bis etwa zum Gelenkbereich des Schuhwerks reicht, und daß die im Gelenkbereich aus dem Bund austretenden Enden der Kordel nach innen und parallel zu Laufsohle angeordnet und miteinander verbunden sind.The shape can also be ensured that the lower End portion of the top layer is shaped into a bundle by the bottom End area turned over and connected to the upper layer that in the A cord is inlaid over the lower end of the top layer becomes. It has proven particularly useful if the federal government in Pointed area of the footwear is arranged and up to about the joint area of the Footwear is sufficient, and that those emerging from the waistband in the joint area Ends of the cord arranged inwards and parallel to the outsole and with each other are connected.

Besonders günstig ist es, wenn die Kordel ein Monofilament ist, da hierbei die Kordel vollständig vom Kleber eingehüllt werden kann. Bei Verwendung von Multifilamentfäden für die Kordel, besteht bei einigen Ausführungsformen die Gefahr, daß über die Kordel infolge von Kapillarkräften Wasser bis zur Brandsohle vordringen kann.It is particularly favorable if the cord is a monofilament, since this is the Cord can be completely wrapped in the adhesive. When using Multifilament threads for the cord exist in some embodiments Danger of water reaching the insole through the cord due to capillary forces can penetrate.

Wie bereits ausgeführt, ist es besonders vorteilhaft, wenn die Laufsohle mit der Funktionsschicht über einen wasserdichten Kleber verklebt ist. Wird als Material für die Laufsohle ein nicht vollständig wasserdichtes Material gewählt, beispielsweise Leder, empfiehlt es sich auch die Brandsohle mit der Laufsohle mit einem wasserdichten Kleber zu verkleben, um einem eventuell über die Laufsohle eindringendem Wasser eine Sperrschicht entgegenzusetzen.As already stated, it is particularly advantageous if the outsole with the Functional layer is glued over a waterproof adhesive. Used as a material for the outsole selected a not fully waterproof material, for example Leather, it is also recommended to use the insole with the outsole glue waterproof glue to prevent any penetration through the outsole Water to oppose a barrier layer.

Das erfindungsgemäße wasserdichte Schuhwerk weist bevorzugt ein Futter auf, welches ein Laminat ist, bei welchem mit der Funktionsschicht eine Futterschicht verbunden ist. Als Funktionsschicht hat sich eine Membran bestens bewährt, die unter dem Warenzeichen SYMPATEX vertrieben wird.The waterproof footwear according to the invention preferably has a lining, which is a laminate in which the functional layer is a lining layer connected is. A membrane has proven its worth as a functional layer is sold under the trademark SYMPATEX.

In Spezialfällen kann es von Vorteil sein, wenn die der Futterschicht abgewandte Seite der Funktionsschicht mit einer textilen Verstärkungsschicht verbunden ist, und die Verklebung der Laufsohle mit dem Endbereich der Funktionsschicht derart erfolgt ist, daß die textile Verstärkungsschicht vollständig in der für die Verklebung erforderliche Klebeschicht eingebettet ist. Wesentlich hierbei ist, daß die Klebeschicht die Fäden der textilen Verstärkungsschicht vollständig umhüllt, um eine wasserdichte Sperre von außen zu gewährleisten. Insbesondere sollten für die textile Verstärkungsschicht auch Monofilamente eingesetzt werden, um der Eindringung von Wasser über Kapillarkräfte, wie es bei Multifilamentgarnen häufig beobachtet wird, wirksam vorzubeugen.In special cases it can be an advantage if the one facing away from the lining layer Side of the functional layer is connected to a textile reinforcement layer, and the outsole is bonded to the end region of the functional layer in this way is that the textile reinforcement layer is completely in the required for the gluing Adhesive layer is embedded. It is essential that the adhesive layer the threads of the textile reinforcement layer completely covered to a ensure watertight lock from the outside. In particular, for the Textile reinforcement layer also used monofilaments to prevent penetration from water to capillary forces, as is common with multifilament yarns is observed to effectively prevent.

Besonders günstig hierbei ist es, wenn der die Laufsohle und die Funktionsschicht verbindende Kleber auch den inneren Rand des umgeschlagenen Endbereichs der Funktionsschicht umfaßt. In dem Falle, bei dem der Kleber das zur Sohle hin angeordnete textile Flächengebilde des Futters nicht vollständig durchdringt, der Kleber aber den inneren Rand des umgeschlagenen Endbereichs des Futters umfaßt, kann sich der Kleber dort mit der Funktionsschicht dicht verbinden, da am Rand die Funktionsschicht gut zugänglich ist.It is particularly favorable here if the outsole and the functional layer connecting adhesive also the inner edge of the folded end of the Functional layer includes. In the case where the glue is towards the sole arranged textile fabrics of the lining does not completely penetrate the But glue the inner edge of the folded end of the lining includes, the adhesive there can bond tightly to the functional layer, because on Edge of the functional layer is easily accessible.

In Figur 1 und 2 ist die Oberschicht mit 1 bezeichnet. Innerhalb der Oberschicht 1 ist ein Futter 2 angeordnet, welches im unteren Bereich umgeschlagen ist, und dessen innerer Rand des umgeschlagenen Endbereichs bis zur Naht 4 reicht. Die Naht 4 verbindet den unteren Endbereich des Futters 2 mit einer Brandsohle 3, deren Außenkante ebenfalls im Bereich der Naht 4 liegt. Der Fersenbereich ist durch eine Kappe 5 verstärkt. Im Gelenkbereich ist mit der Oberschicht 1 ein Gitter 6 aus Monofilamenten über die Naht 7 vernäht. Ebenfalls ist im Spitzenbereich ein Gitter 8 über eine nicht gezeigte Naht mit der Oberschicht 1 vernäht. Das Futter 2 besteht erfindungsgemäß aus einem Laminat, welches zur Fußseite hin eine Futterschicht und zur Sohlenseite hin eine Funktionsschicht aufweist, auf welche die nicht gezeigte Sohle aufgeklebt wird. Wesentlich ist, daß der Kleber eine flächige Verbindung zwischen Sohle und Funktionsschicht aufweist, um ein Eindringen von Wasser von außen in Richtung Brandsohle 3 zu vermeiden. In der Regel wird auch die Brandsohle 3 mit der Laufsohle verklebt. Dies ist auf jeden Fall zu empfehlen, wenn für die Sohle ein Material ausgewählt wird, welches über die Zeit gesehen Wasser aufnimmt, wie es beispielsweise bei nicht imprägniertem Leder der Fall ist. Es ist auch von Vorteil, wenn das Futter auf der dem Fuß abgewandten Seite der Funktionsschicht eine textile Verstärungsschicht aufweistIn Figures 1 and 2, the top layer is designated 1. Inside the top layer 1 a feed 2 is arranged, which is turned over in the lower area, and its inner edge of the folded end area extends to seam 4. The seam 4 connects the lower end of the lining 2 with an insole 3, the The outer edge is also in the area of the seam 4. The heel area is through a Cap 5 reinforced. A grid 6 is formed in the joint area with the top layer 1 Monofilaments sewn over seam 7. There is also a grid 8 in the tip area sewn to the top layer 1 via a seam, not shown. The lining 2 exists According to the invention from a laminate, which has a lining layer towards the foot side and has a functional layer on the sole side, on which the not shown sole is glued on. It is essential that the adhesive is flat Connection between sole and functional layer to prevent penetration of Avoid water from the outside towards the insole 3. As a rule, too the insole 3 glued to the outsole. This is definitely recommended if a material is selected for the sole that is seen over time Absorbs water, as is the case with non-impregnated leather, for example. It is also advantageous if the lining is on the side of the foot facing away from the foot Functional layer has a textile reinforcement layer

Figur 3 zeigt eine weitere Ausführungsform des erfindungsgemäßen Schuhs, bei dem gleiche Teile wie bei der Ausführungsform gemäß der Figuren 1 und 2 mit gleichen Ziffern versehen wurden und hier nicht noch einmal beschrieben werden. Bei dieser Ausführungsform ist die Oberschicht im Spitzenbereich nach unten umgeschlagen (Bereich 9). Direkt in der Spitze ist aus der Oberschicht ein Zwickel herausgeschnitten. Die durch den Ausschnitt des Zwickels entstandenen Ränder der Oberschicht sind über eine Naht 10 miteinander verbunden. In dem nach innen umgeschlagenen Bereich 9 der Oberschicht 1 können noch weitere Zwickel herausgeschnitten sein, wobei wiederum die entstehenden Ränder über Nähte verbunden werden. Auch im unteren Endbereich des Futters empfiehlt es sich, in den Bereichen, in denen der Schuh relativ kleine Radien aufweist, wie es zumindest im Spitzen- und im Fersenbereich der Fall ist, im umgeschlagenen Endbereich einzuschneiden und die entstandenen Ränder miteinander wasserdicht zu verbinden. Diese wasserdichte Verbindung kann beispielsweise durch Verkleben erreicht werden. Es können aber auch die durch Ausschneiden eines Zwickels entstandenen Ränder miteinander vernäht werden, wobei dann jedoch die Naht wirksam abgedichtet werden muß, was beispielsweise durch ein wasserdichtes Klebeband erreicht werden kann, welches den Bereich der Naht vollständig abdeckt. Die Wasserdichtigkeit solcher Nähte muß auf jeden Fall auf der zur Sohle hin gewandten Seite des unteren Endbereichs der Funktionsschicht gewährleistet sein, um eine saubere Abdichtung zu erreichen.Figure 3 shows a further embodiment of the shoe according to the invention, at the same parts as in the embodiment according to Figures 1 and 2 with have been given the same numbers and are not described again here. In this embodiment, the top layer is down in the tip region handled (area 9). There is a gusset in the top layer directly in the tip cut out. The edges of the The upper layer is connected to one another via a seam 10. In the inside folded-over area 9 of the upper layer 1 can still further gussets be cut out, again the resulting edges connected by seams become. In the lower end of the feed it is also advisable to use the Areas in which the shoe has relatively small radii, as at least in The tip and heel area is the case to cut in the folded end area and to connect the resulting edges together watertight. This watertight connection can be achieved, for example, by gluing become. But it can also be the result of cutting out a gusset Edges are sewn together, but then the seam is effective must be sealed, for example by a waterproof tape can be achieved which completely covers the area of the seam. The Such seams must in any case be watertight on the side facing the sole Side of the lower end region of the functional layer must be guaranteed to to achieve a clean seal.

In Figur 4 und 5 ist eine weitere Ausführungsform des erfindungsgemäßen Schuhs dargestellt, wobei wiederum für gleiche Teile die Bezugszeichen der Figuren 1 bis 3 verwendet wurden. Das untere Ende der Oberschicht 1 ist zu einem Bund 12, auch Kordeldurchzug oder Tunnel genannt, geformt, in welchen Bund 12 eine Kordel 11 eingelegt ist. Der Bund 12 reicht vom Spitzenbereich bis zum Gelenkbereich des Schuhs, wobei die beiden Enden der Kordel im Gelenkbereich aus dem Bund austreten und über einen Knoten miteinander verbunden sind.FIGS. 4 and 5 show a further embodiment of the shoe according to the invention shown, again the same reference numerals of Figures 1 to 3 for the same parts were used. The lower end of the top layer 1 is made into a collar 12, too Cord passage or tunnel, formed, in which collar 12 a cord 11 is inserted. The collar 12 extends from the tip area to the joint area of the Schuhs, the two ends of the cord in the joint area from the waistband emerge and are connected by a knot.

In Figur 6 ist die Untersicht auf einen Schuh dargestellt, bei dem der vordere Teil des Schuhs mit dem erfindungsgemäßen Schuhwerk ausgestattet ist, während der hintere, zur Ferse hin gerichtete Teil des Schuhs in klebegezwickter Ausführungsform hergestellt ist. Hierzu ist die Oberschicht 1 im Fersenbereich nach unten verlängert und nach innen derart umgeschlagen, daß der umgeschlagene Teil 1' der Oberschicht 1 parallel zur Laufsohle angeordnet ist. In dem Bereich, in dem die Oberschicht 1 nach innen umgeschlagen ist, liegt die Außenkontur der Brandsohle 13 an der Funktionsschicht 2 an (Umrißbrandsohle). Die Oberschicht 1 ist mit der Funktionsschicht 2 zusammen um die Außenkontur der Brandsohle 13 geschlagen. Die beiden Brandsohlenteile 3 und 13 können hierbei aus einem Stück oder zweigeteilt ausgeführt sein, wobei bei einer Zweiteilung die beiden Brandsohlenteile 3 und 13 sich überlappen. Im gezeigten Falle überlappen sich die Brandsohlenteile 3 und 13 im Bereich des Haltegitters 6. Bei der dargestellten Ausführungsform des erfindungsgemäßen Schuhwerks, bei dem sich die beiden Brandsohlenteile 3 und 13 überlappen, ergibt sich eine besonders hohe Flexibilität im Überlappungsbereich, so daß dieser Überlappungsbereich an der Stelle des Schuhs angeordnet sein sollte, wo Flexibilität gefordert wird.FIG. 6 shows the bottom view of a shoe in which the front part of the shoe is equipped with the footwear according to the invention, during the rear part of the shoe facing the heel in a sticky embodiment is made. For this purpose, the top layer 1 is down in the heel area extended and turned inside so that the turned part 1 'of Upper layer 1 is arranged parallel to the outsole. In the area where the The upper layer 1 is turned inwards, the outer contour of the insole lies 13 on the functional layer 2 (outline insole). The upper layer 1 is with the Functional layer 2 wrapped together around the outer contour of the insole 13. The two insole parts 3 and 13 can be made from one piece or be carried out in two parts, the two insole parts being divided in two 3 and 13 overlap. In the case shown, the insole parts overlap 3 and 13 in the area of the holding grid 6. In the illustrated embodiment of the Footwear according to the invention, in which the two insole parts 3 and 13 overlap, there is a particularly high degree of flexibility in the overlap area, so that this overlap area can be arranged at the location of the shoe should where flexibility is required.

Bei dem erfindungsgemäßen Schuhwerk ist es nicht erforderlich, daß die Oberschicht mit dem Futter verklebt ist. Es reicht in der Regel aus, wenn, wie oben ausgeführt, Haltegitter an die Oberschicht angenäht (angestrobelt) sind oder der untere Teil der Oberschicht nach innen umgeschlagen ist. Auch dann, wenn der untere Teil der Oberschicht nach innen umgeschlagen ist, ist nicht unbedingt ein Klebezwicken - eine Verklebung mit dem umgeschlagenen Endbereich des Futters - erforderlich, da die Halterung über den Kleber, mit dem die Laufsohle angeklebt wird erfolgt. Insofern kann das erfindungsgemäße Schuhwerk besonders wirtschaftlich hergestellt werden.In the footwear according to the invention, it is not necessary that the Upper layer is glued to the lining. It is usually sufficient if, as above executed, holding grids are sewn onto the top layer (strobed) or the lower part of the upper layer is turned inside. Even if the bottom part of the top layer is turned inside is not necessarily one Adhesive pinch - a glue to the folded end of the lining - required because the bracket is over the glue with which the outsole is glued he follows. In this respect, the footwear according to the invention can be particularly economical getting produced.
