Description

Die Erfindung betrifft ein wasserdichtes Schuhwerk mit einem Außenschaft, einem eine wasserdichte, wasserdampfdurchlässige Funktionsschicht enthaltenden Innenschaft, einer Brandsohle und einer Laufsohle.The invention relates to a waterproof footwear with an outer shaft, an inner shaft containing a waterproof, water vapor permeable functional layer, an insole and an outsole.

Ein derartiges Schuhwerk ist beispielsweise aus US 4 599 810 bekannt geworden. Bei diesem bekannten Schuhwerk ist der Innenschaft in Form eines Sockens ausgebildet. Auf diese Weise ist der Fuß des Trägers allseitig von dem wasserdichten, wasserdampfdurchlässigen Innenschaft umfasst, so dass in das Schuhwerk eindringendes Wasser keine Möglichkeit hat, bis zum Fuß des Trägers vorzudringen. Obwohl inzwischen vielfältige Konstruktionen von Schuhwerk bekannt geworden sind, welche zur Einsparung von Funktionsschichtmaterial den Innenschaft nach unten offen ausbilden, gilt dieses aus US 4 599 810 bekannte Schuhwerk immer noch als die Ausführungsform, welche eindringendes Wasser am sichersten vermeidet.Such footwear is for example off US 4 599 810 known. In this known footwear of the inner shaft is formed in the form of a sock. In this way, the foot of the wearer is encompassed on all sides by the waterproof, water vapor permeable inner shaft, so that water entering the footwear has no opportunity to penetrate to the foot of the wearer. Although in the meantime diverse constructions of footwear have become known, which form the inner shaft open down to save functional layer material, this applies US 4 599 810 known footwear still as the embodiment which avoids the most penetrating water.

Das Einbringen des sockenförmigen Innenschaftes in das Innere des Schuhwerkes ist kaum ohne Faltenbildung möglich. Auch kann es beim Tragen des Schuhwerkes zu weiterer Faltenbildung kommen, was regelmäßig vom Träger des Schuhwerkes als unangenehm empfunden wird.The introduction of the sock-shaped inner shaft in the interior of the footwear is hardly possible without wrinkles. Also, it can lead to further wrinkling when wearing the footwear, which is regularly perceived by the wearer of the footwear as unpleasant.

Aufgabe der vorliegenden Erfindung ist es, ein Schuhwerk der eingangs genannten Art zur Verfügung zu stellen, bei dem die Gefahr der Faltenbildung des Innenschaftes zumindest deutlich reduziert ist.Object of the present invention is to provide a footwear of the type mentioned, in which the risk of wrinkling of the inner shaft is at least significantly reduced.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Brandsohle eine in Längsrichtung verlaufende schlitzförmige Öffnung aufweist, dass der Innenschaft eine zur Sohle gerichtete, mit der Länge der schlitzförmigen Öffnung der Brandsohle korrelierende Verlängerung aufweist, und dass die Verlängerung des Innenschaftes durch die schlitzförmige Öffnung der Brandsohle hindurchgezogen und sohlenseitig auf der Brandsohle abgelegt ist.This object is achieved in that the insole has a longitudinally extending slot-shaped opening, that the inner shaft has a directed to the sole, correlating with the length of the slot-shaped opening of the insole extension, and that the extension of the inner shaft through the slit-shaped opening of the insole pulled through and placed on the sole side of the insole.

Bei der Herstellung des erfindungsgemäßen Schuhwerkes wird die Verlängerung des Innenschaftes durch die schlitzförmige Öffnung der Brandsohle hindurchgezogen. Nachdem der Leisten in den Innenschaft eingeführt ist, kann der Innenschaft im Innenraum des Schuhwerkes durch entsprechendes Ziehen an der Verlängerung des Innenschaftes gestrafft werden, wodurch vorhandene Falten im Innenraum entfernt werden. Anschließend wird die Verlängerung des Innenschaftes fixiert. Dies kann beispielsweise dadurch bewerkstelligt werden dass die Verlängerung mit der Brandsohle verklebt wird. Es ist aber auch möglich die Fixierung der Verlängerung durch das Ankleben einer vorgefertigten Laufsohle oder durch das Anspritzen einer Laufsohle durchzuführen.In the manufacture of the footwear according to the invention, the extension of the inner shaft is pulled through the slot-shaped opening of the insole. After the strip has been inserted into the inner shaft, the inner shaft in the interior of the footwear can be tightened by pulling on the extension of the inner shaft, which removes any wrinkles in the inner space. Subsequently, the extension of the inner shaft is fixed. This can for example be accomplished by the extension is glued to the insole. But it is also possible to perform the fixation of the extension by sticking a prefabricated outsole or by spraying an outsole.

Bevorzugt zeichnet sich das erfindungsgemäße Schuhwerk dadurch aus, dass die hindurchgezogene Verlängerung des Innenschaftes zur Sohle hin offen ist und zwei zur Längserstreckung der schlitzförmigen Öffnung der Brandsohle zumindest in etwa symmetrische Bereiche umfasst, die jeweils eine Kante der schlitzförmigen Öffnung der Brandsohle umschließen und sohlenseitig auf der Brandsohle aufliegen. Dadurch, dass die Verlängerung des Innenschaftes nach unten offen ausgebildet ist, kann bei der Herstellung des Schuhs die Straffung des Innenschaftes günstiger bewerkstelligt werden, da die beiden Bereiche einzeln gefasst und gezogen werden können.Preferably, the footwear according to the invention is characterized in that the pulled-extended extension of the inner shaft is open to the sole and two to the longitudinal extension of the slot-shaped opening of the insole comprises at least approximately symmetrical areas, each enclose an edge of the slot-shaped opening of the insole and the sole side on the Lie up insole. The fact that the extension of the inner shaft is designed to be open at the bottom, the streamlining of the inner shaft can be accomplished cheaper in the manufacture of the shoe, since the two areas can be taken individually and pulled.

Es hat sich bei dem erfindungsgemäßen wasserdichten Schuhwerk als Vorteil herausgestellt, wenn die beiden Enden der schlitzförmigen Öffnung der Brandsohle gegenüber der Schlitzbreite erweitert ausgebildet sind. Diese Erweiterungen an den beiden Enden der schlitzförmigen Öffnung in der Brandsohle dienen bei der Herstellung des Schuhwerkes als Arbeitshilfe, um die Abdichtung des Innenschaftes günstiger vornehmen zu können. So hat es sich zur Vereinfachung der Abdichtung besonders bewährt, wenn die Verlängerung des Innenschaftes in den Erweiterungen der schlitzförmigen Öffnungen der Brandsohle gefaltet ist.It has been found in the waterproof footwear according to the invention as an advantage when the two ends of the slot-shaped opening of the insole opposite the slot width are formed extended. These extensions at the two ends of the slot-shaped opening in the insole serve in the manufacture of footwear as a working aid to make the sealing of the inner shaft cheaper. Thus, it has proven particularly useful for the simplification of the seal when the extension of the inner shaft is folded in the extensions of the slot-shaped openings of the insole.

Die Abdichtung des Innenschaftes erfolgt regelmäßig entweder über die für das Schuhhandwerk üblichen Kleber, beispielsweise Polyurethankleber, oder durch das Sohlenmaterial an sich, wenn das Schuhwerk mit einer angespritzten Laufsohle ausgestattet werden soll, die an das vorgefertigte Schuhwerk als flüssiges Polymer angespritzt, zur Laufsohle geformt und danach ausgehärtet wird. Bei angespritzten Sohlen ist es häufig nicht erforderlich, die Verlängerung des Innenschaftes zu fixieren, da beim Anspritzen des noch flüssigen Laufsohlenmaterials dieses die Verlängerung des Innenschaftes umspült und wasserdicht in das Sohlenmaterial einbettet. Sofern die Verlängerung des Innenschaftes nach unten offen ausgebildet ist, wird die im Schlitzbereich der Brandsohle sich nach dem Ablegen der Bereiche des Innenschaftes auf die Brandsohle ausgebildete Öffnung zum Inneren des Schuhwerkes vom noch flüssigen Laufsohlenmaterial ausgefüllt und wasserdicht verschlossen. In diesem Falle ist auch keine große Anforderung an die Wasserdichtigkeit der Brandsohle zu stellen, da das Laufsohlenmaterial beim Anspritzen auch bis zur Brandsohle vordringt und sich mit dieser wasserdicht verklebt.The sealing of the inner shaft is done regularly either on the customary for the shoe industry adhesive, such as polyurethane adhesive, or by the sole material itself, if the footwear is to be equipped with a molded outsole, molded on the prefabricated footwear as a liquid polymer, molded to the outsole and is cured afterwards. When molded soles, it is often not necessary to fix the extension of the inner shaft, since when spraying the still liquid outsole material this laps the extension of the inner shaft and waterproof embedded in the sole material. If the extension of the inner shaft is designed to be open at the bottom, the opening formed in the slot area of the insole after the areas of the inner shaft have been laid down on the insole is filled to the inside of the footwear by the still fluid outsole material and sealed in a watertight manner. In this case, no great requirement is placed on the waterproofness of the insole, since the outsole material also penetrates to the insole during injection molding and glued to this waterproof.

Insbesondere bei Schuhen, bei denen eine vorgefertigte Laufsohle angebracht wird, ist es empfehlenswert, wenn die Brandsohle sohlenseitig wasserdicht ausgebildet ist. Dabei ist es auch von Vorteil, wenn die Bereiche der Verlängerung des Innenschaftes sohlenseitig mit der Brandsohle wasserdicht verklebt sind.In particular, for shoes in which a prefabricated outsole is attached, it is recommended that the insole is formed waterproof side sohlenseitig. It is also advantageous if the areas of the extension of the inner shaft are glued waterproof sohlenseitig with the insole.

Sofern die Verlängerung des Innenschaftes nach unten offen ausgebildet ist, sollte besondere Sorgfalt darauf gelegt werden, dass die von den beiden Bereichen der Innenschaftverlängerung im Schlitzbereich der Brandsohle noch vorhandene Öffnung zum Schuhinnenraum gut abgedichtet wird. Dies kann im einfachsten Fall durch den für die Verklebung der Laufsohle verwendeten Kleber erfolgen. Im Falle von Laufsohlen die an sich nicht wasserdicht sind, beispielsweise Laufsohlen aus Leder, empfiehlt es sich, diese Öffnung zum Inneren des Schuhwerkes mit einer Dichtschicht, die entweder als Beschichtung aufgetragen oder angespritzt oder als vorgefertigte Dichtschicht aufgeklebt werden kann, zu versehen, bevor die Laufsohle angeklebt wird.If the extension of the inner shaft is designed to be open at the bottom, special care should be taken to ensure that the opening to the shoe interior which is still present in the slot area of the insole of the two areas of the inner shaft extension is well sealed. This can be done in the simplest case by the adhesive used for the gluing of the outsole. In the case of outsoles that are not waterproof per se, such as leather soles, it is recommended that this opening to the interior of the footwear with a sealing layer, which can be either applied as a coating or molded or glued as a prefabricated sealing layer to provide before the Outsole is glued on.

Es lässt sich nicht immer sicher stellen, dass die flächige Verbindung zwischen Brandsohle und Laufsohle vollständig gelingt, so dass Wasser dann noch zwischen Brandsohle und Laufsohle eindringen und bis zur Verlängerung des Innenschaftes vordringen kann. Da das Futter des Innenschaftes häufig aus saugfähigen textilem Material gebildet ist, würde in diesem Fall das Wasser bis in den Innenraum des Schuhwerkes vordringen. Um dieses wirksam zu vermeiden, zeichnet sich das erfindungsgemäße wasserdichte Schuhwerk auch dadurch aus, dass die Enden der Bereiche der Verlängerung des Innenschaftes umgeschlagen sind und mit sich selbst verklebt sind. Auf diese Weise kann eindringendes Wasser nicht mehr bis zum Futter des Innenschaftes vordringen.It is not always possible to ensure that the flat connection between the insole and outsole is completely successful, so that water can then penetrate between the insole and the outsole and can penetrate until the inner shaft lengthens. Since the lining of the inner shaft is often formed of absorbent textile material, in this case, the water would penetrate into the interior of the footwear. In order to avoid this effectively, the waterproof footwear according to the invention is also distinguished by the fact that the ends of the regions of the extension of the inner shaft are turned over and glued to themselves. In this way, penetrating water can no longer penetrate to the lining of the inner shaft.

Die Ausbildung eines sockenförmigen Innenschaftes, wie er beispielsweise bei den in US 4 599 810 beschriebenen Ausführungsformen eingesetzt wird, erfolgt in der Regel derart, dass der Innenschaft aus mehreren Teilstücken zusammengesetzt wird. Die Teilstücke werden miteinander verbunden und mit einem Klebeband abgeklebt, um die aneinander stoßenden Teilstücke im Stoß wasserdicht auszubilden. Diese Art der Herstellung des Innenschaftes 2, welcher zumindest eine wasserdichte, wasserdampfdurchlässige Funktionsschicht und eine zur Innenseite gerichtete Futterschicht aufweist, wird auch bei den in den Figuren dargestellten Ausführungsformen mit Ausnahme des Bereichs, in dem der Innenschaft durch die schlitzförmige Öffnung der Brandsohle 4 gezogen ist, angewandt. Hierbei sind die über eine Naht 5a miteinander verbundenen Teilstücke über ein Klebeband 3 an ihrer Verbindungsstelle (Naht 5a) wasserdicht abgedichtet.The formation of a sock-shaped inner shaft, as he, for example, in the in US 4 599 810 described embodiments is usually carried out such that the inner shaft is composed of several sections. The sections are connected to each other and taped with an adhesive tape to waterproof form the abutting sections in shock. This type of production of the inner shaft 2, which has at least one waterproof, water vapor permeable functional layer and an inner lining layer, is also in the embodiments shown in the figures, with the exception of the area in which the inner shaft is pulled through the slot-shaped opening of the insole 4 , applied. In this case, the sections connected to one another via a seam 5a are sealed watertight via an adhesive tape 3 at their connection point (seam 5a).

Die Brandsohle 4 weist eine in Längsrichtung verlaufende schlitzförmige Öffnung auf, die in den Figuren durch die Kanten 4a und 4b begrenzt ist. Diese schlitzförmige Öffnung der Brandsohle 4 weist an ihren beiden Enden jeweils eine Erweiterung 4c und 4d auf. In diesen Erweiterungen 4c und 4d ist jeweils das Ende 3a, 3b des Klebebandes 3 sichtbar. Eine Verlängerung 8 des Innenschaftes 2 ist durch die schlitzförmige Öffnung der Brandsohle 4 hindurch gezogen und auf der Brandsohle 4 sohlenseitig abgelegt. In der in den Figuren dargestellten Ausführungsformen ist diese Verlängerung jeweils nach unten offen und umschließt jeweils eine Kante 4a oder 4b der schlitzförmigen Öffnung der Brandsohle 4.The insole 4 has a longitudinally extending slot-shaped opening which is bounded in the figures by the edges 4a and 4b. This slot-shaped opening of the insole 4 has at its two ends in each case an extension 4c and 4d. In these extensions 4c and 4d respectively the end 3a, 3b of the adhesive tape 3 is visible. An extension 8 of the inner shaft 2 is pulled through the slot-shaped opening of the insole 4 through and stored on the insole 4 sole side. In the embodiments shown in the figures this extension is open at the bottom and each encloses an edge 4a or 4b of the slot-shaped opening of the insole 4.

Gemäß der Figuren 1, 3 und 5 weist die Verlängerung 8 des Innenschaftes 2 Enden 7 auf, die umgeschlagen und mit sich selbst verklebt sind. Im Bereich der Erweiterungen 4c und 4d der schlitzförmigen Öffnung der Brandsohle 4 ist die Verlängerung des Innenschaftes diagonal gefaltet (Falten 6), wodurch eine Abdichtung im Bereich der Erweiterung 4c bzw. 4d mittels Kleber oder mittels des beim Anspritzen der Laufsohle flüssigen Kunststoffes erleichtert wird. An die Brandsohle 4 ist ein Außenschaft 1 über die Naht 5 angenäht. Diese Naht 5 wird in der Regel angebracht, bevor der Innenschaft 2 in den Außenschaft 1 eingeführt wird, um eine Verletzung der Funktionsschicht des Innenschaftes zu vermeiden.According to the FIGS. 1 . 3 and 5 has the extension 8 of the inner shaft 2 ends 7, which are folded and glued to themselves. In the region of the extensions 4c and 4d of the slot-shaped opening of the insole 4, the extension of the inner shaft is folded diagonally (folds 6), whereby a seal in the area of the extension 4c or 4d is facilitated by means of adhesive or by means of the plastic liquid during injection molding of the outsole. To the insole 4, an outer shaft 1 is sewn over the seam 5. This seam 5 is usually applied before the inner shaft 2 is inserted into the outer shaft 1 in order to avoid a violation of the functional layer of the inner shaft.

In Figur 2 ist der Schnitt AA dargestellt, wobei zusätzlich noch eine angespritzte Laufsohle 11 angebracht ist. In diesem Bereich weist die Brandsohle 4 keine schlitzförmige Öffnung auf. Der Innenschaft ist im Brandsohlenbereich mit sich selbst über die naht 5a verbunden und zur Brandsohle hin über das Klebeband 3 abgedichtet.In FIG. 2 the section AA is shown, wherein additionally a molded outsole 11 is attached. In this area, the insole 4 has no slot-shaped opening. The inner shaft is connected in the insole area with itself on the seam 5a and sealed to the insole over the tape 3.

Gemäß Figur 3, die den Schnitt BB des erfindungsgemäßen Schuhwerkes gemäß Figur 1 darstellt, umschließt die zur Sohle hin offene Verlängerung des Innenschaftes die Kanten 4a und 4b der schlitzförmigen Öffnung der Brandsohle 4. Die Enden 2a und 2b der Verlängerung des Innenschaftes sind mit sich selbst verklebt. Das Sohlenmaterial ist derart angespritzt, dass es sich mit der Brandsohle 4, den Enden 2a und 2b der Verlängerung des Innenschaftes und der Verlängerung bis zur Innenseite des Schuhwerkes wasserdicht verbunden hat.According to FIG. 3 , the section BB of the footwear according to the invention according to FIG. 1 1, the extension of the inner shaft open toward the sole surrounds the edges 4a and 4b of the slot-shaped opening of the insole 4. The ends 2a and 2b of the extension of the inner shaft are glued to themselves. The sole material is injection-molded in such a way that it has a watertight connection to the insole 4, the ends 2a and 2b of the extension of the inner shaft and the extension to the inside of the footwear.

In Figur 4 ist wiederum der Schnitt BB dargestellt, wobei die Enden 2c und 2d nicht mit sich selbst verbunden sind. Bei dieser Ausführungsform ist es nicht erforderlich, die Enden 2c und 2d mit der Brandsohle 4 zu verkleben. Beim Anspritzen des Sohlenmaterials umfließt dieses die Enden 2c und 2d, so dass kein Wasser mehr bis zum Futter des Innenschaftes 2 vordringen kann.In FIG. 4 Again, the section BB is shown with the ends 2c and 2d are not connected to itself. In this embodiment, it is not necessary to glue the ends 2c and 2d to the insole 4. When spraying of the sole material flows around the ends 2c and 2d, so that no more water can penetrate to the lining of the inner shaft 2.

In Figur 5 ist eine weitere Ausführungsform des erfindungsgemäßen Schuhwerkes gemäß Figur 1 (Schnitt BB) mit einer angeklebten Laufsohle 12 dargestellt. Um im Sohlenbereich eine Abdichtung zu erreichen, kann die Öffnung der Verlängerung des Innenschaftes zum Schuhinneren durch eine wasserdichte Schicht 9 abgedeckt sein, die mit der Verlängerung des Innenschaftes wasserdicht verbunden ist. Des Weiteren kann der Brandsohlenbereich zwischen Außenschaft und der Verlängerung des Innenschaftes mit einer wasserdichten Ausballschicht 10 wasserdicht verbunden sein. Diese Ausballschicht kann beispielsweise durch Anspritzen eines noch flüssigen Kunststoffmaterials erzeugt werden. Die wasserdichte Schicht 9 und die Ausballschicht 10 kann im einfachsten Fall auch dadurch erreicht werden, dass auf die der Brandsohle zugewandte Fläche der Laufsohle 12 eine satte Schicht eines Klebers aufgetragen wird, bevor die Laufsohle 12 mit dem übrigen Schuhwerk verbunden wird.In FIG. 5 is a further embodiment of the footwear according to the invention according to FIG. 1 (Section BB) shown with a glued outsole 12. In order to achieve a seal in the sole region, the opening of the extension of the inner shaft to the shoe interior can be covered by a waterproof layer 9, which is waterproof connected to the extension of the inner shaft. Furthermore, the insole region between the outer shaft and the extension of the inner shaft may be watertightly connected to a watertight Ausballschicht 10. This Ausballschicht can be generated for example by spraying a still liquid plastic material. The waterproof layer 9 and the Ausballschicht 10 can be achieved in the simplest case, that on the insole facing surface of the outsole 12 a rich layer of adhesive is applied before the outsole 12 is connected to the rest of footwear.

Claims (7)

  1. Waterproof shoe structure with an exterior upper (1), an interior upper (2) comprising a waterproof, water vapour permeable functional layer, an insole (4) and an outsole (11, 12), characterised in that the insole (4) has a slit-shaped opening running in longitudinal direction, that the interior upper (2) has an extension oriented towards the sole correlating with the length of the slit-shaped opening in the insole (4), and that the extension of the interior upper is drawn through the slit-shaped opening of the insole (4) and is deposited on the insole (4) on the sole side.
  2. Waterproof shoe structure according to Claim 1, characterised in that the drawn-through extension of the interior upper (2) is open towards the outsole (11, 12) and comprises two areas (2a, 2b or 2c, 2d) that are at least roughly symmetrical to the longitudinal extension of the slit-shaped opening in the insole, each of which surrounds one edge (4a, 4b) of the slit-shaped opening in the insole (4) and rests on the insole (4) on the sole side.
  3. Waterproof shoe structure according to Claim 1 or 2, characterised in that the two ends (4c, 4d) of the slit-shaped opening in the insole (4) are wider than the slit width.
  4. Waterproof shoe structure according to Claim 3, characterised in that the extension of the interior upper (2) is folded in the wider sections (4c, 4d) of the slit-shaped openings in the insole (4).
  5. Waterproof shoe structure according to Claims 1 to 4, characterised in that the insole (4) is waterproof on the sole side.
  6. Waterproof shoe structure according to Claims 2 to 5, characterised in that the sections of the extension of the interior upper (2) are glued water-tight to the insole (4) on the sole side.
  7. Waterproof shoe structure according to Claims 2 to 6, characterised in that the ends (2a, 2b) of the sections of the extension of the interior upper (2) are folded over and glued to themselves.
