Abstract
Description
Die Erfindung betrifft einen Schuh mit einem Schaft und einem an der Innenseite des Schafts anliegenden, im wesentlichen wasserdichten Futter, wobei ein Befestigungsrand des Schafts mit einer Zwischensohle verbunden ist, an der Außenseite des Befestigungsrandes ein wasserdichter Verbindungsstreifen anliegt und dieser wasserdichte Verbindungsstreifen mit einer wenigstens eine wasserdichte Schicht aufweisenden Sohlenkonstruktion wasserdicht verbunden ist, und wobei die Wasserführung des Befestigungsrandes zur Zwischensohle unterbrochen ist.The invention relates to a shoe with a shaft and a substantially watertight lining lying against the inside of the shaft, a fastening edge of the shaft being connected to a midsole, a watertight connecting strip resting on the outside of the fastening edge and this waterproof connecting strip having at least one has a waterproof layer-connected sole construction, and the water flow of the fastening edge to the midsole is interrupted.
Für einen Schuh, der hauptsächlich im Außenbereich, d.h. in freier Umgebung, verwendet werden soll, stellt seine Dichtigkeit gegenüber eindringendem Wasser, insbesondere beim Kauf, ein wichtiges Kriterium dar. Um eine ausreichende Wasserdichtigkeit zu erreichen, weist bei einem aus der DE-A-38 40 087 entnehmbaren Schuh der eingangs genannten Art der in sich nicht wasserdichte Schaft einen als Befestigungsrand dienenden, wasserdichten Randstreifen auf. Damit von außen über den Übergangsbereich von dem Schaft zu dem Randstreifen kein Wasser in diesen Schuh eindringen kann, ist der wasserdichte Verbindungsstreifen dabei so an der Außenseite des Schafts angeordnet, daß er diesen Übergang überdeckt. Um zu verhindern, daß Wasser von dem Schaft über den Zwischenraum zwischen dem wasserdichten Futter und dem Schaft in das Innere des Schuhs gelangen kann, ist des weiteren zwischen dem wasserdichten Futter einerseits und dem Schaft bzw. dem Randstreifen andererseits eine Dichtmittelschicht angeordnet. Somit kann weder von außen, d.h. von dem Übergangsbereich zwischen dem Schaft und dem Randstreifen, noch über den wasserführenden Schaft Wasser in das Innere des Schuhs gelangen. Dieser Schuh weist aber einen verhältnismäßig komplizierten Aufbau auf und läßt sich deshalb nur unter hohem Fertigungsaufwand herstellen.For a shoe that is to be used primarily outdoors, ie in an open environment, its tightness against ingress of water, especially when buying, is an important criterion. To achieve sufficient water resistance, one of the DE-A- 38 40 087 removable shoe of the type mentioned in the non-waterproof shaft on a serving as a fastening edge, waterproof edge strip. So that no water can penetrate into this shoe from the outside via the transition area from the shaft to the edge strip, the waterproof connecting strip is arranged on the outside of the shaft in such a way that it covers this transition. In order to prevent water from getting into the interior of the shoe from the shaft via the gap between the waterproof lining and the shaft, a layer of sealant is furthermore arranged between the waterproof lining on the one hand and the shaft or the edge strip on the other. Thus, water cannot get into the inside of the shoe from the outside, ie from the transition region between the upper and the edge strip, nor via the water-carrying upper. However, this shoe has a relatively complicated structure and can therefore only be produced at high production costs.
Es ist Aufgabe der vorliegenden Erfindung, einen Schuh der eingangs genannten Art zu schaffen, der sich bei einer guten Abdichtung gegenüber eindringendem Wasser einfach herstellen läßt.It is an object of the present invention to provide a shoe of the type mentioned, which can be easily manufactured with a good seal against water penetration.
Die vorstehende Aufgabe wird dadurch gelöst, daß der Verbindungsstreifen den Befestigungsrand des Schafts und das innenliegende Futter U-förmig umgreift, daß der innenliegende Schenkel des U-förmigen Verbindungsstreifens mit dem im wesentlichen wasserdichten Futter wasserdicht verbunden ist und daß der U-förmige Verbindungsstreifen mit der Zwischensohle verbunden ist.The above object is achieved in that the connecting strip surrounds the fastening edge of the shaft and the inner lining in a U-shape, that the inner leg of the U-shaped connecting strip is connected to the essentially waterproof lining in a watertight manner and that the U-shaped connecting strip is connected to the Midsole is connected.
Die vorgeschlagene Lösung ermöglicht, daß sowohl für den Befestigungsrand des Schafts als auch für den Bereich zwischen dem wasserdichten Futter und dem Schaft keine weitere besondere Maßnahme vorgesehen werden muß, um eine gute Wasserabdichtung des gesamten Schuhs zu erzielen. Durch den U-förmig umgreifenden Verbindungsstreifen sowie der wasserdichten Verbindung zwischen dem wasserdichten Futter und dem Verbindungsstreifen wird auf einfache Weise verhindert, daß am Ende des Schafts bzw. des Befestigungsrandes Wasser von dem Schaft in das Innere des Schuhs übertreten kann.The proposed solution enables that no further special measure has to be provided both for the fastening edge of the upper and for the area between the waterproof lining and the upper in order to achieve a good water seal of the entire shoe. The U-shaped encompassing connecting strip and the watertight connection between the waterproof lining and the connecting strip prevent in a simple manner that water can pass from the upper into the interior of the shoe at the end of the upper or the fastening edge.
Um dem Schuh eine gute Stabilität zu verleihen, kann die Zwischensohle von einer Brandsohle gebildet sein, an welcher der Verbindungsstreifen befestigt ist.In order to give the shoe good stability, the midsole can be formed by an insole to which the connecting strip is attached.
Die Befestigung des Verbindungsstreifens an der Brandsohle kann hierbei durch eine Verklebung erfolgen, insbesondere durch eine Verklebung mittels einer Schmelzkleberschicht im Rahmen eines AGO-Zwickverfahrens. Das AGO-Zwickverfahren stellt dabei insbesondere für die industrielle Fertigung des erfindungsgemäßen Schuhs ein leicht zu beherrschendes Herstellungsverfahren dar.The connecting strip can be attached to the insole by gluing, in particular by gluing using a hot melt adhesive layer as part of an AGO lasting process. The AGO lasting process is an easy to control manufacturing process, especially for the industrial production of the shoe according to the invention.
Um einen möglichst kompakten Aufbau des Schuhs zu erreichen, wird weiterhin vorgeschlagen, daß der einerseits an dem wasserdichten Futter anliegende innere Schenkel des Verbindungsstreifens andererseits an der Brandsohle befestigt ist. Alternativ besteht hierzu die Möglichkeit, daß der Verbindungsstreifen in seinem Stegbereich, d.h. außerhalb des Endes des Befestigungsrandes und des wasserdichten Futters, mit der Brandsohle verbunden wird.In order to achieve the most compact possible structure of the shoe, it is further proposed that the inner leg of the connecting strip, which on the one hand rests on the waterproof lining, is attached on the other hand to the insole. Alternatively, there is the possibility that the connecting strip in its web area, i.e. outside the end of the fastening edge and the waterproof lining to which the insole is connected.
Bei der Herstellung des Schuhs, insbesondere der Befestigung des Schafts an der Zwischensohle, können erhebliche, an dem Schaft angreifende Spannkräfte auftreten. Um diese Spannkräfte von dem mit dem Verbindungsstreifen U-förmig umspritzten Schaft aufnehmen zu können, wird weiterhin vorgeschlagen, daß der an dem Befestigungsrand des Schafts anliegende Schenkel des Verbindungsstreifens mit dem Befestigungsrand derart fest verbunden ist, daß diese Verbindung die Spannkräfte bei der Herstellung der Befestigung zwischen Verbindungsstreifen und Brandsohle aufnehmen kann.During the manufacture of the shoe, in particular the fastening of the upper to the midsole, considerable tension forces acting on the upper can occur. In order to be able to absorb these clamping forces from the shaft which is overmolded in a U-shape with the connecting strip, it is further proposed that the leg of the connecting strip resting on the fastening edge of the shaft is firmly connected to the fastening edge in such a way that this connection is the clamping forces during the manufacture of the fastening between connecting strips and insole.
Für die Zwischensohle kann auch eine flexible Sohle vorgesehen werden. Hierbei besteht die Möglichkeit, daß die Zwischensohle mit dem Verbindungsstreifen durch eine Verbindungsnaht, insbesondere durch eine Strobelnaht, verbunden wird. Da sich die Verbindungsnaht besonders einfach, beispielsweise auf einer Strobelmaschine, herstellen läßt, kann ein derartiger Schuhaufbau insbesondere bei Billig-Schuhen oder aber auch, wegen seiner besonderen Flexibilität, bei Sportschuhen vorgesehen werden.A flexible sole can also be provided for the midsole. Here, there is the possibility that the midsole is connected to the connecting strip by a connecting seam, in particular by a strobe seam. Since the connecting seam can be produced particularly easily, for example on a strobe machine, such a shoe structure can be provided in particular for cheap shoes or, because of its particular flexibility, in sports shoes.
Um zu verhindern, daß über die Verbindungsnaht Wasser von dem Schaft zu der Zwischensohle und damit in das Innere des Schuhs gelangen kann, wird weiterhin vorgeschlagen, daß die Verbindungsnaht den Verbindungsstreifen in dessen Stegbereich, d.h. außerhalb des Endes des Befestigungsrandes und des wasserdichten Futters, durchsetzt.In order to prevent water from getting from the upper to the midsole and thus into the interior of the shoe via the connecting seam, it is further proposed that the connecting seam penetrate the connecting strip in its web region, ie outside the end of the fastening edge and the waterproof lining .
Das wasserdichte Futter kann einen unterschiedlichen Aufbau aufweisen. So besteht beispielsweise die Möglichkeit, daß das vorzugsweise bis in den Einstiegsbereich des Schuhs reichende, wasserdichte Futter lediglich durch eine einzige wasserdichte Schicht gebildet wird. Darüber hinaus kann das im wesentlichen wasserdichte Futter dampfdurchlässig ausgebildet sein, wofür beispielsweise eine Folie aus gerecktem Polytetrafluoräthylen, eine Polyestermembran oder eine mikroporöse Polyurethanschicht vorgesehen werden kann. Das im wesentlichen wasserdichte Futter kann aber auch aus einer wasserdichten bzw. dampfdurchlässigen Schicht sowie einer inneren und/oder einer äußeren, textilartigen Beschichtung bzw. Schicht aufgebaut sein. Sowohl die innere als auch die äußere textilartige Beschichtung kann hierbei aus einem Gewebe, z.B. aus einem Polyamidfadengewebe oder einem Polyesterfadengewebe aus beispielsweise monofilen Fäden, gefertigt sein. Beide Beschichtungen haben dabei u.a. die Aufgabe die im wesentlichen wasserdichte Schicht des Futters vor mechanischen Beschädigungen zu schützen und darüber hinaus, insbesondere die innere textilartige Beschichtung, einen guten Tragkomfort zu ermöglichen. Um bei Ausführung des wasserdichten Futters mit einer textilartigen Beschichtung auf seiner Innenseite eine gute Wasserdichtigkeit zu erreichen, kann vorgesehen werden, daß der innere, dem wasserdichten Futter anliegende Schenkel des Verbindungsstreifens die textilartige Schicht derart durchdringt, daß er wasserdicht mit dem wasserdichten Futter verbunden ist.The waterproof lining can have a different structure. For example, there is the possibility that the waterproof lining, which preferably reaches into the entry area of the shoe, is formed only by a single waterproof layer. In addition, the essentially waterproof lining can be vapor-permeable, for which purpose, for example, a film made of stretched polytetrafluoroethylene, a polyester membrane or a microporous polyurethane layer can be provided. The essentially waterproof lining can, however, also be made up of a waterproof or vapor-permeable layer and an inner and / or an outer, textile-like coating or layer. Both the inner and the outer textile-like coating can be made of a fabric, e.g. be made of a polyamide thread or a polyester thread made of, for example, monofilament threads. Both coatings have i.a. the task of protecting the essentially waterproof layer of the lining from mechanical damage and, in addition, in particular the inner textile-like coating, to enable good wearing comfort. In order to achieve good watertightness when the waterproof lining is made with a textile-like coating on its inside, it can be provided that the inner leg of the connecting strip which lies against the waterproof lining penetrates the textile-like layer in such a way that it is watertightly connected to the waterproof lining.
Für die Anbringung des Verbindungsstreifens auf dem Befestigungsrand können unterschiedliche Verfahren vorgesehen werden. So besteht beispielsweise die Möglichkeit, daß der Verbindungsstreifen auf dem Befestigungsrand aufvulkanisiert wird. Besonders einfach läßt sich der Verbindungsstreifen an dem Befestigungsrand und an dem an dem Schaft anliegenden Futter anbringen, wenn dieser auf dem Befestigungsrand und auf das an dem Befestigungsrand anliegende Futter aufgespritzt wird.
Für den Verbindungsstreifen können die verschiedensten Materialien vorgesehen werden. Vorzugsweise wird vorgeschlagen, daß der Verbindungsstreifen aus Gummi mit einer Shorehärte im Bereich von ca. 50 bis 80, vorzugsweise von ca. 60 bis 70 , hergestellt wird.Different methods can be provided for attaching the connecting strip to the fastening edge. For example, there is the possibility that the connecting strip is vulcanized onto the fastening edge. The connecting strip can be attached particularly easily to the fastening edge and to the lining lying against the shaft when it is open is sprayed onto the fastening edge and onto the lining lying against the fastening edge.
A wide variety of materials can be provided for the connecting strip. It is preferably proposed that the connecting strip be made of rubber with a Shore hardness in the range of approximately 50 to 80, preferably approximately 60 to 70.
Die Sohlenkonstruktion kann ebenfalls einen ganz unterschiedlichen Aufbau aufweisen. So besteht zum einen die Möglichkeit, daß die Sohlenkonstruktion lediglich durch eine Laufsohle gebildet ist. Ebenso kann aber die Sohlenkonstruktion durch eine Laufsohle und einen zwischen Laufsohle und Zwischensohle angeordneten, die Lauf- und Dämpfungseigenschaften verbessernden Dämpfungskeil gebildet sein, wobei dieser vorzugsweise zur Bildung der wasserdichten Schicht der Sohlenkonstruktion aus einem in sich wasserdichten Material hergestellt ist. Des weiteren besteht die Möglichkeit, daß die in sich wasserdichte Schicht der Sohlenkonstruktion von einer wasserdichten, ggf. dampfdurchlässigen Folie gebildet wird.The sole construction can also have a very different structure. On the one hand, there is the possibility that the sole construction is only formed by an outsole. Likewise, however, the sole construction can be formed by an outsole and a damping wedge arranged between the outsole and midsole, which improves the running and damping properties, wherein this is preferably made of an inherently waterproof material to form the waterproof layer of the sole construction. There is also the possibility that the inherently waterproof layer of the sole construction is formed by a waterproof, possibly vapor-permeable film.
Hierbei stehen für die Sohlenkonstruktion die verschiedensten Materialien zur Verfügung. Insbesondere kann die Laufsohle aus Kautschuk mit einer Shorehärte im Bereich von ca. 50 bis 80, vorzugsweise von ca. 60 bis 70 , und der ggf. vorhandene Dämpfungskeil aus PU-Schaum mit einer Shorehärte im Bereich von ca. 50 bis 70 , vorzugsweise von ca. 55 bis 60 , hergestellt sein.A wide variety of materials are available for the sole construction. In particular, the outsole can be made of rubber with a Shore hardness in the range from approximately 50 to 80, preferably from approximately 60 to 70, and the possibly present damping wedge made of PU foam with a Shore hardness in the range from approximately 50 to 70, preferably from about 55 to 60.
Um bei der Herstellung des Schuhs das Gebilde aus Schaft und Zwischensohle besonders einfach gegenüber der Sohlenkonstruktion ausrichten zu können, wird weiterhin vorgeschlagen, daß die Sohlenkonstruktion an ihrer zu dem Gebilde aus Schaft und Verbindungsstreifen einerseits und Zwischensohle andererseits weisenden Seite schalenförmig ausgebildet ist. Die besonders gute Wasserdichtigkeit ermöglicht, daß dar Schuh als hochschäftiger Schuh, insbesondere Sport- oder Wanderstiefel, ausgebildet sein wird. Es besteht aber auch die Möglichkeit, daß er als Halbschuh ausgebildet wird.In order to be able to align the structure of the upper and midsole particularly simply with respect to the sole construction in the manufacture of the shoe, it is further proposed that the sole construction on its side facing the structure of the upper and connecting strip on the one hand and the midsole on the other hand have a shell-shaped design. The particularly good water resistance enables the shoe to be designed as a high-profile shoe, in particular sports or hiking boots. But there is also the possibility that it is designed as a shoe.
Zur Herstellung des erfindungsgemäßen Schuhs kann zum einen vorgesehen werden, daß der U-förmige Verbindungsstreifen auf den Schaft aufgebracht wird, während dieser im wesentlichen senkrecht zur Zwischensohlenebene über die Zwischensohlenebene nach unten vorsteht und daß der Befestigungsrand samt Futter und Verbindungsstreifen an der Zwischensohle angelegt und an der Zwischensohle befestigt wird.For the manufacture of the shoe according to the invention, it can be provided, on the one hand, that the U-shaped connecting strip is applied to the upper, while the upper protrudes downward substantially perpendicularly to the midsole plane and that the fastening edge, including the lining and connecting strip, is placed on and on the midsole the midsole is attached.
Alternativ kann hierzu vorgesehen werden, daß der auf dem Schaft aufgebrachte U-förmige Verbindungsstreifen mit seinem an der Zwischensohle anliegenden inneren Schenkel und mit seinem an dem Zwischensohlenrand anliegenden Steg durch eine Verbindungsnaht, insbesondere Strobelnaht, mit der Zwischensohle vernäht wird und anschließend der Verbindungsstreifen samt Befestigungsrand und
wasserdichtem Futter um 180° um die Randkante der Zwischensohle umgeklappt wird.Alternatively, it can be provided that the U-shaped connecting strip applied to the shaft with its inner leg resting against the midsole and with its web resting against the midsole edge is sewn to the midsole by means of a connecting seam, in particular a strobing seam, and then the connecting strip including the fastening edge and
waterproof lining is folded over 180 ° around the edge of the midsole.

Vorteilhafterweise wird dabei ein Material gewählt, welches soweit flexibel und räumlich verformbar ist, daß der Verbindungsstreifen zusammen mit dem von ihm umgebenen Schaft und Futter leicht und ohne Verformung umgebogen bzw. umgeklappt werden kann.The connecting
Das Gebilde aus Schaft 12, Futter 14 und Verbindungsstreifen 16 einerseits sowie der Brandsohle 18 andererseits wird von einer Sohlenkonstruktion 20 getragen, die aus einer Laufsohle 20a und einem Dämpfungskeil 20b besteht. An seiner Oberseite weist der Dämpfungskeil 20b einen entlang seines Randes umlaufenden Absatz auf, auf welchem der den Schaft 12 und das Futter 14 umgreifende Verbindungsstreifen 16 aufliegt. Darüber hinaus ist die Oberseite des Dämpfungskeils 20b schalenförmig ausgebildet. Die Laufsohle 20a kann aus Kautschuk (Gummi) mit einer Shorehärte im Bereich von ca. 50 bis 80, vorzugsweise von ca. 60 bis 70 , hergestellt sein. Für den Dämpfungskeil kann als Material ein PU-Schaum mit einer Shorehärte von ca. 50 bis 70 , vorzugsweise von ca. 55 bis 60, vorgesehen werden.The structure of the
Zur Herstellung des Schuhs gemäß Fig. 1 wird zunächst der Schaft 12 und das innenliegende Futter im Bereich des Befestigungsrandes 12a des Schafts 12 mit dem Verbindungsstreifen 16 U-förmig umspritzt, wobei der Schaft 12 und das innenliegende Futter 14 über die Zwischensohlenebene nach unten vorstehen. Daraufhin wird das Gebilde aus Schaft 12, Futter 14 und Verbindungsstreifen 16 um ca. 90° umgeklappt und in einem Zwickverfahren, insbesondere einem AGO-Zwickverfahren, mit der Zwischensohle bzw. Brandsohle 18 verklebt. Bei dem AGO-Zwickverfahren wird der Verbindungsstreifen 16 von nicht weiter dargestellten Spannzangen erfaßt, über einen Leisten L gezogen und gegen die Brandsohle 18 angedrückt, wobei zwischen der äußeren Seite des inneren Schenkels 16b des Verbindungsstreifens 16 und der Brandsohle 18 ein schnell härtender Schmelzkleber eingebracht wird (vgl. hierzu Fig. 1). Der Schmelzkleber hat dabei den Vorteil, daß er in der Zwickmaschine in verhältnismäßig kurzer Zeit aushärtet, so daß die Verweilzeit des Schuhs beim Zwicken in der Zwickmaschine reduziert wird. Anschließend wird das so entstandene Gebilde aus Schaft 12, Futter 14 und Verbindungsstreifen 16 einerseits sowie der Brandsohle 18 andererseits mit der Sohlenkonstruktion 20 verklebt, insbesondere ebenfalls mittels einer Schmelzkleberschicht 22.To manufacture the shoe according to FIG. 1, first the
In der Fig. 3 ist eine alternative Ausführungsform dargestellt. Hierbei sind analoge Teile mit den gleichen Bezugszeichen versehen wie in Fig. 1, jeweils vermehrt um die Zahl 100.An alternative embodiment is shown in FIG. 3. Here, analog parts are provided with the same reference numerals as in FIG. 1, each increased by the number 100.
Der Schaft 112 und das im wesentlichen wasserdichte Futter 114 sind hierbei ebenfalls von einem Verbindungsstreifen 116 im Bereich des Befestigungsrandes 112a des Schaftes 112 U-förmig umgeben, wobei dieser Verbindungsstreifen 116 ebenfalls angespritzt ist. Der Stegbereich 116c des Verbindungsstreifens 116 ist im Gegensatz zu der Ausführungsform gemäß Fig. 1 hier vergrößert ausgebildet und dient dabei zur Aufnahme einer Verbindungsnaht 124, insbesondere einer Strobelnaht, mittels welcher die vorzugsweise flexible Zwischensohle 118 mit dem Verbindungsstreifen 116 verbunden wird. Hierzu wird das Gebilde aus Schaft 112, Futter 114 und Verbindungsstreifen 116 mit der Außenseite des inneren Schenkels 116b des Verbindungsstreifens 116 auf der Oberseite der Zwischensohle 118 in der Weise angeordnet, daß der Rand des Steges 116c mit dem Zwischensohlenrand 118a abschließt. Anschließend wird die Strobelnaht 124 angebracht (vgl. Fig. 3). Daraufhin wird das Gebilde aus Schaft 112, Futter 114 und Verbindungsstreifen 116 um ca. 180° in die in der Fig. 4 gezeigten Stellung umgeklappt. Das so vernähte Gebilde aus Schaft 112, Futter 114 und Verbindungsstreifen 116 einerseits sowie Zwischensohle 118 andererseits wird daraufhin mittels einer Kleberschicht 122, insbesondere einer Schmelzkleberschicht, mit der ähnlich zu der Fig. 1 aufgebauten Sohlenkonstruktion 120 verbunden.The
