Description

Die Erfindung betrifft ein wasserdichtes Schuhwerk mit einem Außenschaft, einem Innenschaft, der zumindest eine wasserdichte, wasserdampfdurchlässige Funktionsschicht und ein Futter enthält, einer Brandsohle und einer Laufsohle, wobei das untere Ende des Außenschaftes und die Brandsohle über eine Naht miteinander verbunden sind.The invention relates to a waterproof footwear with an outer shaft, a Inner shaft that is at least a waterproof, water vapor permeable Functional layer and a lining contains, an insole and an outsole, being the lower end of the outer shaft and the insole are sewn together are connected.

Ein derartiges Schuhwerk für Schuhe mit angespritzter Laufsohle ist aus EP 0 679 347 A bekannt. Der untere Außenschaftrand und der untere Innenschaftrand ist bei dem bekannten Schuhwerk auf ungleiche Länge geschnitten, wobei beim Anspritzen das flüssige Laufsohlenmaterial derart geführt werden muss, dass der untere Innenschaftrand anschließend vom Laufsohlenmaterial eingebettet ist. Abgesehen davon, dass diese Art nur für Schuhwerk mit angespritzten Laufsohlen eine Lösung bietet, bereitet bei der Herstellung des bekannten Schuhwerkes die dichte Einbettung des unteren Innenschaftrandes Probleme. Insbesondere dann, wenn das flüssige Sohlenmaterial beim Anspritzen der Laufsohle den unteren Innenschaftrand gegen den Außenschaft presst, ist es praktisch nicht vermeidbar, dass das auf der Innenseite des Innenschaftes angeordnete Futter in Kontakt mit dem Außenschaft gebracht wird, so dass Feuchtigkeit, die im Außenschaft enthalten sein kann, über die Kontaktstellen des Futters in das Innere des Schuhs transportiert werden kann. Such footwear for shoes with a molded outsole is out EP 0 679 347 A is known. The lower outer edge and the lower Inner edge is cut to an unequal length in the known footwear, the liquid outsole material must be guided in such a way during injection, that the lower inner edge is then embedded by the outsole material is. Apart from the fact that this type is only for footwear with molded Soles offers a solution, prepares in the manufacture of the known Footwear the dense embedding of the lower inner margin problems. Especially when the liquid sole material is molded onto the Outsole presses the lower inner edge of the inner shaft against the outer shaft, it is practically unavoidable, that on the inside of the inner shaft arranged lining is brought into contact with the outer shaft so that Moisture that can be contained in the outer shaft through the contact points of the Lining can be transported inside the shoe.

Aufgabe der vorliegenden Erfindung ist es, bei einem Schuhwerk der eingangs genannten Art diese Nachteile zu vermeiden.The object of the present invention is at the beginning of a footwear to avoid these disadvantages.

Gelöst wird diese Aufgabe bei einem Schuhwerk gemäß Oberbegriff des Anspruchs 1 dadurch, dass die Funktionsschicht am unteren Schaftende des Innenschaftes das Futter und gegebenenfalls weitere Schichten des Innenschaftes um einen unteren Funktionsschichtbereich überragt, dass der überragende Funktionsschichtbereich mit dem unteren Außenschaftrand wasserdicht verbunden ist, und dass die Naht, die das untere Ende des Außenschaftes und die Brandsohle miteinander verbindet, ausschließlich in dem Bereich des unteren Endes des Schaftes angeordnet ist, in welchem der untere Funktionsschichtbereich mit dem Außenschaft wasserdicht verbunden ist.This task is solved with footwear according to the preamble of the claim 1 in that the functional layer on the lower shaft end of the inner shaft Lining and possibly other layers of the inner shaft around a lower one Functional layer area dominates that the outstanding functional layer area with the lower edge of the shaft is watertight and that the seam that the connects the lower end of the outer shaft and the insole, is arranged exclusively in the region of the lower end of the shaft, in which the lower functional layer area with the outer shaft waterproof connected is.

Auf diese überraschend einfache Weise kann Feuchtigkeit, die im Außenschaft vorhanden ist nicht mehr bis zum Futter vordringen, weil das Futter bereits über der Nahtstelle endet und somit keine Möglichkeit hat, die im Außenschaft enthaltende Feuchtigkeit aufzusaugen und ins Innere des Schuhs zu transportieren. Die wasserdichte Verbindung des überragenden Funktionsschichtbereiches mit dem unteren Außenschaftrand, die in der Regel über Kleber, beispielsweise Polyurethankleber erzeugt wird, bewirkt, dass die empfindliche, meist dünne Funktionsschicht durch den Außenschaft stabilisiert wird, so dass auch bei längerem Gebrauch des Schuhwerks eine Verletzung der Funktionsschicht in der Regel vermieden wird. Gleichzeitig werden durch die wasserdichte Verbindung des unteren Funktionsschichtbereichs mit dem Außenschaftrand die in die Funktionsschicht beim Vernähen entstandenen Nählöcher abgedichtet. Dies gelingt besonders gut, wenn für das Nahtmaterial ein Monofilfaden verwendet worden ist.In this surprisingly simple way, moisture can accumulate in the outer shaft is no longer available to reach the feed because the feed is already above the Interface ends and therefore has no possibility, the one contained in the outer shaft Absorb moisture and transport it inside the shoe. The watertight connection of the outstanding functional layer area with the lower outer edge, which is usually over glue, for example Polyurethane glue is produced, which causes the sensitive, mostly thin Functional layer is stabilized by the outer shaft, so that even with longer Use of footwear usually violates the functional layer is avoided. At the same time, the waterproof connection of the lower Functional layer area with the outer edge in the functional layer at Sewing the resulting sewing holes sealed. This works particularly well if for the suture material has been used as a monofilament.

Die wasserdichte und wasserdampfdurchlässige Funktionsschicht ist sehr dünn ― in der Regel 10 bis 100 µm- und somit sehr empfindlich. Die Funktionsschicht dicker auszubilden, scheitert schon daran, weil die Wasserdampfdurchlässigkeit der Funktionsschicht umso geringer wird, je dicker die Funktionsschicht ausgebildet ist. Bei bisher bekannt gewordenen Schuhwerken wird deshalb regelmäßig davon ausgegangen, dass für den Innenschaft ein Laminat, das die Funktionsschicht und ein diese Funktionsschicht verstärkendes und/oder stabilisierendes textiles Flächengebilde enthält, eingesetzt wird, wobei dieses textile Flächengebilde häufig das Innenfutter ist. Auf diese Weise soll eine Verletzung der dünnen und empfindlichen Funktionsschicht vermieden werden. Insbesondere wird bei bekannten Schuhwerken dafür gesorgt, dass in den Bereichen großer Belastung des Schuhwerkes, beispielsweise in den Bereichen, an denen sich eine Naht befindet, das verstärkende und stabilisierende textile Flächengebilde auf jeden Fall vorhanden ist. Die vorliegende Erfindung zeigt, dass in diesen Bereichen großer Belastung auf die verstärkende Wirkung des auf die Funktionsschicht normalerweise auflaminierten textilen Flächengebildes verzichtet werden kann.The waterproof and water vapor permeable functional layer is very thin - in usually 10 to 100 µm- and therefore very sensitive. The functional layer thicker training fails because the water vapor permeability of the The thicker the functional layer is, the smaller the functional layer becomes. In the case of footwear that has become known so far, it is therefore regularly removed assumed that for the inner shaft a laminate covering the functional layer and a textile that reinforces and / or stabilizes this functional layer Contains fabrics, is used, this textile fabric often the lining is. This is supposed to be an injury to the thin and sensitive functional layer can be avoided. In particular, in known Footwear ensured that in the areas of high stress Footwear, for example in the areas where there is a seam, the reinforcing and stabilizing textile fabric is definitely present is. The present invention shows that in these areas there is great stress the reinforcing effect of what is normally laminated onto the functional layer textile fabric can be dispensed with.

Die Herstellung des Innenschaftes des erfindungsgemäßen Schuhwerkes kann durch Laminate erfolgen, bei denen die Funktionsschicht an einer Seite übersteht. Im Zuge einer wirtschaftlichen Herstellung wird bevorzugt der Innenschaft unter Verwendung eines üblichen Laminats hergestellt und bei oder nach der Herstellung des Innenschaftes der untere Funktionsschichtbereich von den anderen, das Laminat bildenden Flächengebilden befreit. Dies kann beispielsweise durch Abschaben mit einem Messer erfolgen.The inner shaft of the footwear according to the invention can be produced through laminates in which the functional layer protrudes on one side. in the In the course of economical production, the inner shaft is preferred Made using a standard laminate and during or after manufacture of the inner shaft the lower functional layer area from the others, the laminate forming fabrics exempted. This can be done, for example, by scraping with a knife.

Das erfindungsgemäße Schuhwerk zeichnet sich insbesondere dadurch aus, dass der untere Funktionsschichtbereich länger als der Außenschaft ausgebildet ist und der untere Funktionsschichtbereich derart umgeschlagen ist, dass er eine Umschlagkante bildet, welche zumindest in etwa bündig mit dem unteren Außenschaftende angeordnet ist. Auf diese Weise ist die Funktionsschicht im kritischen Bereich, dem Nahtbereich, doppelt vorhanden. Es ist dabei zweckmäßig, den umgeschlagenen Bereich der Funktionsschicht mit dem gegenüberliegenden Bereich der Funktionsschicht zu verkleben, sofern diese gegenüberliegen. The footwear according to the invention is characterized in particular by the fact that the lower functional layer area is longer than the outer shaft and the lower functional layer area has been turned over so that it is a Cover edge forms which is at least approximately flush with the lower Foreign end is arranged. In this way, the functional layer in the critical area, the seam area, duplicate. It is advisable the folded area of the functional layer with the opposite Area of the functional layer to be glued, provided they are opposite.

Je nach Schuhwerkkonstruktion kann es von Vorteil sein, wenn der untere Funktionsschichtbereich nach außen umgeschlagen ist. Dabei hat es sich besonders bewährt, wenn der untere Funktionsschichtbereich nach außen und um das untere Ende des Außenschaftes herumgeschlagen ist und der untere Funktionsschichtbereich sowohl von innen her als auch von außen mit dem unteren Bereich des Außenschaftendes wasserdicht verbunden ist, wobei die Naht, die das untere Ende des Schaftes mit der Brandsohle verbindet, ausschließlich in dem Bereich angeordnet ist, in welchem die Funktionsschicht sowohl innen wie auch außen mit dem Außenschaftende wasserdicht verbunden ist.Depending on the footwear construction, it can be advantageous if the lower one Functional layer area is turned outwards. It was special proven when the lower functional layer area to the outside and around the lower End of the outer shaft and the lower functional layer area both from the inside and from the outside with the lower area of the Exterior of the waterproof is connected, with the seam covering the lower end of the upper connects to the insole, only in the area is arranged in which the functional layer with both inside and outside the outer end is connected watertight.

Eine weitere Sicherheit gegen eindringendes Wasser bei einem erfindungsgemäßen Schuhwerk mit angeklebter Sohle kann dadurch erreicht werden, dass die angeklebte Sohle an der Außenkante eine umlaufende Erhöhung aufweist, welche die das untere Schaftende mit der Brandsohle verbindende Naht überdeckt. Hierbei ist es besonders zweckmäßig, die umlaufende Erhöhung mit dem Außenschaftrand wasserdicht, beispielsweise durch Verkleben, zu verbinden. Bei einem erfindungsgemäßen Schuhwerk mit angeklebter Sohle kann es auch zweckmäßig sein, zunächst eine innere, bevorzugt wasserdicht ausgebildete Sohle auf den zur Laufsohle hin gerichteten Bereich des Schuhwerkes aufzukleben oder anzuspritzen, um eine eventuell sich bildenden Spalte zwischen dem unteren Funktionsschichtbereich und der Brandsohle wirksam abzudichten.Another security against ingress of water in an inventive Footwear with a glued-on sole can be achieved in that the glued sole on the outer edge has a circumferential increase, which that covers the seam connecting the lower shaft end with the insole. in this connection it is particularly useful to increase the circumferential edge with the outer edge waterproof, for example by gluing. At a Footwear according to the invention with a glued-on sole can also be useful be, first an inner, preferably waterproof sole on the to Glue or spray on the outsole facing area of the footwear, a possibly forming gap between the lower functional layer area and effectively seal the insole.

Bei einem erfindungsgemäßen Schuhwerk mit angespritzter Sohle, welche die eben erwähnte angespritzte Innensohle oder die Laufsohle selbst sein kann, hat es sich besonders bewährt, wenn die Brandsohle zumindest in ihrem Randbereich vom beim Anspritzen flüssigen Sohlenmaterial durchdringbar ausgebildet ist, dass die den Außenschaft und die Brandsohle verbindende Naht in diesem Randbereich angeordnet ist, und dass das Sohlenmaterial den durchdringbaren Bereich zumindest im Bereich der Naht durchdrungen hat. Auf diese Weise wird der kritische Bereich des erfindungsgemäßen Schuhwerkes besonders wirksam dicht ausgebildet. In the case of footwear according to the invention with a molded-on sole, which is just the injection molded insole or the outsole itself, it has Particularly proven if the insole at least in its edge area from when Injection liquid sole material is designed penetrable that the Outer shaft and seam connecting the insole in this edge area is arranged, and that the sole material the penetrable area has penetrated at least in the area of the seam. This way the critical The area of the footwear according to the invention is particularly effectively tight.

Von besonderem Vorteil ist es bei diesem erfindungsgemäßen Schuhwerk, wenn der untere Funktionsschichtbereich länger als der Außenschaft ausgebildet ist und der untere Funktionsschichtbereich derart nach innen umgeschlagen ist, dass sie eine untere Umschlagkante bildet, welche zumindest in etwa bündig mit dem Außenschaftende angeordnet ist. Im unteren Funktionsschichtbereich ist auf diese Weise die Funktionsschicht in zwei benachbarten Lagen angeordnet, die bevorzugt miteinander wasserdicht verbunden sind.It is of particular advantage in this footwear according to the invention if the lower functional layer area is longer than the outer shaft and the lower functional layer area is turned in such that it is a forms the lower cover edge, which is at least approximately flush with the Foreign end is arranged. This is in the lower functional layer area Way, the functional layer is arranged in two adjacent layers, which is preferred are connected together watertight.

Das Anspritzen der Sohle bei dem erfindungsgemäßen Schuhwerk gelingt vorzüglich, wenn der vom beim Anspritzen flüssigen Sohlenmaterial durchdringbare Bereich der Brandsohle netzartig ausgebildet ist, wobei die Herstellung eines solchen Schuhwerkes besonders kostengünstig wird, wenn die gesamte Brandsohle aus einem Netz besteht. Um noch eine weitere Sicherheit gegen eindringendes Wasser zu erreichen, besteht dieses Netz aus Monofilfäden.The sole is molded onto the footwear according to the invention excellent if the sole material that can be penetrated by the liquid when sprayed on Area of the insole is network-like, the production of such Footwear becomes particularly inexpensive when the entire insole is off a network exists. For even more security against water ingress To achieve this network consists of monofilament threads.
