Definitions
- a metal layer or metal plate is generally provided between the outsole and the insole in safety shoes. This metal layer or metal plate extends over the entire surface of the insole.
- a shoe with such a damping element is, for example, from DE 93 05 748 U known.
- the one in the DE 93 05 748 U described shoe the insole in the area of the heel has an opening in which an exchangeable damping element is inserted.
- the damping element protrudes beyond the underside of the insole.
- a recess is provided in the shoulder which receives the part of the damping element that extends beyond the underside of the insole.
- Such a damping system is also used in safety shoes in which a penetration-proof metal layer or metal plate is necessary.
- a penetration-proof metal layer or metal plate is necessary.
- an opening is provided in the insole, in which the damping element is inserted.
- the metal layer or the metal plate is guided along the insole and around the damping element, so that the metal plate has a recess for receiving a damping element.
- the outsole which is usually made of plastic, is then attached to the underside of the metal element, in particular molded or foamed.
- the previously known cushioning system cannot be used in safety shoes that have a penetration-proof sole made of a textile material instead of a metal plate or a metal layer.
- a penetration-resistant sole made of textile material cannot be shaped into a three-dimensional structure like a metal in order to provide the recess necessary for receiving the damping element. For safety reasons, it is not allowed to cut a recess in a penetration-proof sole made of textile material. It is currently not possible to provide a safety shoe which has a penetration-resistant sole made of textile material and a cushioning system as described above.
- the object of the present invention is therefore to use the known damping system also in shoes in which no three-dimensionally deformable penetration-proof material layer is used.
- the present object is achieved by a sole suitable for use in a safety shoe, the sole having a toe, metatarsal and heel section as well as a first sole element, which has a toe, metatarsal and heel section, and a second sole element, which has at least having a heel section, wherein the first sole element is a penetration-proof sole which is arranged in layers above the second sole element and is at least partially connected to the second sole element, the second sole element having a recess in which a cushioning element is arranged.
- the damping element is arranged below the penetration-resistant sole, so that no interventions or changes have to be made to a penetration-resistant sole.
- a sole made of a textile material is used as the penetration-resistant sole, this has the additional advantage that the penetration-resistant sole can be used like an insole.
- the internal structure of the shoe is significantly smaller than that of safety shoes with a metal plate and a cushioning system. For the wearer of the safety shoe, this becomes noticeable in that the safety shoe has a lower weight and a slimmer shape.
- the second sole element is preferably made of a textile material or leather, since this material is comparatively easy to process.
- the damping element is releasably fastened in the recess.
- the damping element in particular the damping body, is fastened with an accurate fit in the recess.
- the damping element has a damping body with an upper side, a lower side and side walls, the damping body having a plurality of cavities, which are preferably designed to be open towards the lower side.
- the damping element has a damping body with an upper side, a lower side and side walls, the damping element having a cover on its upper side which at least partially covers the side walls of the damping body protrudes and is preferably formed in one piece with the damping body.
- the cover has a curved surface, as this leads to a kind of air cushion layer between the first sole element and the second sole element and, on the other hand, provides a selective massage effect, which significantly increases the wearing comfort of the safety shoes with this sole.
- the cover has a tab in order to be able to easily remove the damping element from the recess and replace it with another one.
- first sole element and the second sole element form a flap.
- first sole element and the second sole element form a flap.
- the second sole element has a fixed connection in the form of a connecting line to the first sole element, the connecting line preferably running transversely to the longitudinal axis of the sole. This allows the second sole element to be firmly attached to the first sole element, so that the first and second sole elements do not move relative to one another.
- the damping element is preferably arranged between the end of the sole on the heel side and the connecting line, the connecting line here also preferably running transversely to the longitudinal axis of the sole.
- the first sole element forms a type of flap together with the second sole element in the area of the heel section.
- the connecting line is provided in the area of the metatarsal section.
- a connecting line in this area provides a sufficient opening for inserting or replacing the cushioning element in the second sole element.
- the second sole element can thereby be made smaller than the first sole element.
- the second sole element comprises a first edge section, on which the connecting line is provided, and a second edge section, which has the same contour as the first sole element.
- the second sole element is made comparatively small, so that the space requirement of the damping system is very small.
- the present invention also relates to a safety shoe comprising a sole according to the invention.
- the safety shoe comprises an outsole which is firmly connected to the underside of the sole and has a recess for the damping element, the outsole in particular being molded or foamed onto the underside of the shoe.
- an insole can be provided on the sole.
- Fig. 1 and 2 show a sole 10, suitable for use in a safety shoe, in a view from below.
- the sole 10 comprises a first sole element 12 and a second sole element 14.
- the first sole element 12 has a toe, metatarsal and heel section.
- the second sole element 14 has a heel section and a shortened metatarsal section.
- the first sole element 12 is a penetration-proof sole made of a textile material and is arranged in layers above the second sole element 14.
- the term above refers to the intended use in a shoe.
- the second sole element 14 also consists of a textile material. With regard to the penetration security, no requirements are placed on the second sole element 14. Alternatively, the second sole element 14 can thus also be made of leather. In particular, all materials that are usually used for an insole are suitable for the second sole element 14.
- the second sole element 14 is firmly connected to the first sole element 12 in the metatarsal region.
- the second sole element 14 is sewn to the first sole element 12 with the formation of a connecting line 16.
- the second sole element 14 can be glued to the first sole element 12 with the formation of a connecting line.
- the second sole element 14 comprises a first edge section 20, on which the connecting line 16 is provided, and a second edge section 22, which is the same Has contour and size like the first sole element 12.
- the second sole element 14 is attached to the first sole element 12 in such a way that the second edge section 22 of the second sole element 14 is congruent with the corresponding edge section of the first sole element 12.
- the connecting line 16 is a straight line, runs essentially transversely to the longitudinal axis of the sole 10 and extends from one longitudinal side of the sole 10 to the opposite longitudinal side of the sole 10, so that the first sole element 12 is arranged on the second sole element 14 like a flap in the heel area .
- a recess 24 is provided in the heel area, in which a damping element 26 made of an elastic, rubber-like plastic material is arranged.
- the damping element 26 has a predetermined degree of hardness.
- the damping element 26 has a damping body 28 with side walls 29, an upper side and an underside.
- a cover 30 is provided on the upper side of the damping element 26, which laterally projects beyond the side walls 29 of the damping body 28 and is connected in one piece to the damping body 28.
- the cross section of the damping body 28 is precisely shaped to the recess 24 and is held firmly in the recess 24.
- the outside of the side walls 29 thus corresponds to the size of the recess 24, the side walls 29 tapering slightly and the diameter of the damping body 28 in the area of the cover 30 is somewhat larger than in the area of the underside.
- the cover 30 is curved outwards and has a tab 32 on its lateral edge.
- the damping body 28 has a multiplicity of cavities 34 on its underside.
- the cavities 34 have a substantially diamond-shaped cross section. Instead of the diamond-shaped cavities shown, cavities with a different cross-section can also be used. In an embodiment not shown, the cavities are omitted and the damping body is formed from a completely filled block of material.
- the cover 30 rests with its underside on the second sole element 14.
- the cover 30 is located between the first sole element 12 and the second sole element 14.
- the damping body 28 is arranged in the recess 24 of the second sole element 14 and protrudes outward or downward from the second sole element 14.
- the damping element 26 is detachably held in the recess 24 of the second sole element 14 so that defective damping elements 26 can be replaced or damping elements of different degrees of hardness can be inserted in the recess 24 of the second sole element 14.
- the damping element 26 must therefore be held securely in the recess 24 on the one hand. This is achieved in that the cover 30 protrudes laterally beyond the damping body 28. In particular, this prevents the damping element 26 from being inadvertently pressed through the recess 24.
- the tab 32 is provided, with the aid of which a user can pull the damping element 26 out of the recess 24.
- latching elements can also be provided instead of the cover or in addition to the cover, which hold the damping body securely in the recess.
- Fig. 5 shows a safety shoe 40 in cross section.
- the shoe has upper parts 42, an outsole 44 and a metal safety cap 46.
- the outsole 44 has a recess 50.
- outsole 44 is in the Figures 1 and 2 shown sole 10 to recognize.
- An insole 52 is in turn arranged on this sole 10.
- the sole 10 shown is firmly connected on its underside to the outsole 44, the part of the damping body 28 protruding from the second sole element 14 being arranged in the recess 50 of the outsole 44.
- the damping element 26 is detachably arranged in the recess 50 of the outsole 44.
- the type of safety shoe shown is usually the outsole foamed or molded onto the upper parts and insole.
- a placeholder is used in the manufacture of the shoe 40 instead of the intended damping element 28, which corresponds in size and shape to the damping element 28 and can be removed after the outsole has been attached.
- the damping element 28 is only used after the shoe 40 has been completed.
- the insole 52 is removed and then the heel section of the first sole element 12 is raised so that the second sole element 14 with the cushioning element 26 is freely accessible.
- the damping element 26 can then be removed by means of the tab 32.
- the desired new damping element 26 can then be inserted.
- the connecting line it is not absolutely necessary for the connecting line to be provided in the area of the metatarsal section and to extend essentially transversely to the longitudinal axis of the sole.
- the connecting line can run at any point on the second sole element 12.
- the connection line can also be formed on the lateral edge section which is congruent with the first sole element. It is preferred here that the edge section of the second sole element is only partially connected to the first sole element in order to obtain a flap-like connection between the first sole element and the second sole element.
- the second sole element it is not necessary for the second sole element to extend into the area of the metatarsus. It is sufficient if the second sole element covers the heel portion.
- the second sole element has the contour of the first sole element.
- the connection line on which the second sole element is connected to the first sole element can be provided both on the outer edge of the second sole element and transversely or obliquely to the longitudinal axis of the sole in the metatarsal and / or forefoot area or outside the recess.
- the contour of the second sole element is essentially freely selectable.
- the requirement of the second sole element consists essentially in receiving the damping element and forming a flap-like connection with the first sole element.

Description
An Sicherheitsschuhe werden hohe Ansprüche gestellt. So ist ein Kriterium der Sicherheitsschuhe die Durchtrittsicherheit. Um beispielsweise zu verhindern, dass sich auf dem Boden befindliche Nägel oder Schrauben durch die Sohle eines Schuhs hindurchbohren, ist bei Sicherheitsschuhen in der Regel eine Metalllage bzw. Metallplatte zwischen Laufsohle und Brandsohle vorgesehen. Diese Metalllage bzw. Metallplatte erstreckt sich hierbei über die gesamte Fläche der Brandsohle.High demands are made on safety shoes. One of the criteria for safety shoes is penetration resistance. For example, in order to prevent nails or screws on the floor from drilling through the sole of a shoe, a metal layer or metal plate is generally provided between the outsole and the insole in safety shoes. This metal layer or metal plate extends over the entire surface of the insole.
Es besteht vermehrt der Wunsch, auf diese Metalllage bzw. Metallplatte zu verzichten, um einerseits das Gewicht des Schuhs zu reduzieren und um andererseits störende Einflüsse, die von einer Metalllage bzw. Metallplatte beispielsweise auf elektronische Geräte ausgehen, zu verhindern. Aus diesem Grund werden vermehrt durchtrittsichere Sohlen aus einem textilen Material eingesetzt.There is a growing desire to do without this metal layer or metal plate, on the one hand to reduce the weight of the shoe and, on the other hand, to prevent disruptive influences that emanate from a metal layer or metal plate, for example on electronic devices. For this reason, penetration-resistant soles made of a textile material are increasingly being used.
Bei bisher bekannten Schuhen hat sich der Einsatz von einem variablen Dämpfungssystem im Bereich der Ferse bewährt, um den Tragekomfort zu erhöhen. Ein Schuh mit einem solchen Dämpfungselement ist beispielsweise aus der
Ein solches Dämpfungssystem wird auch bei Sicherheitsschuhen eingesetzt, bei denen eine durchtrittsichere Metalllage bzw. Metallplatte notwendig ist. Hierfür ist in der Brandsohle eine Öffnung vorgesehen, in der das Dämpfungselement eingesetzt ist. Die Metalllage oder die Metallplatte wird entlang der Brandsohle und um das Dämpfungselement geführt, so dass die Metallplatte eine Vertiefung zur Aufnahme eines Dämpfungselements aufweist. An der Unterseite des Metallelements ist dann die in der Regel aus Kunststoff bestehende Laufsohle befestigt, insbesondere angeformt oder angeschäumt.Such a damping system is also used in safety shoes in which a penetration-proof metal layer or metal plate is necessary. For this purpose, an opening is provided in the insole, in which the damping element is inserted. The metal layer or the metal plate is guided along the insole and around the damping element, so that the metal plate has a recess for receiving a damping element. The outsole, which is usually made of plastic, is then attached to the underside of the metal element, in particular molded or foamed.
Bei Sicherheitsschuhen, die über eine durchtrittsichere Sohle aus einem texteilen Material anstelle einer Metallplatte oder einer Metalllage verfügen, lässt sich das bisher bekannte Dämpfungssystem nicht einsetzen. Eine durchtrittsichere Sohle aus textilem Material kann nicht wie ein Metall in ein dreidimensionales Gebilde geformt werden, um die für die Aufnahme des Dämpfungselements notwendige Vertiefung bereitzustellen. Aus Sicherheitsgründen ist es nicht erlaubt, eine Aussparung in eine durchtrittsichere Sohle aus textilem Material zu schneiden. Aktuell ist es nicht möglich, einen Sicherheitsschuh bereitzustellen, welcher eine durchtrittsichere Sohle aus textilem Material und ein Dämpfungssystem wie oben beschrieben aufweist.The previously known cushioning system cannot be used in safety shoes that have a penetration-proof sole made of a textile material instead of a metal plate or a metal layer. A penetration-resistant sole made of textile material cannot be shaped into a three-dimensional structure like a metal in order to provide the recess necessary for receiving the damping element. For safety reasons, it is not allowed to cut a recess in a penetration-proof sole made of textile material. It is currently not possible to provide a safety shoe which has a penetration-resistant sole made of textile material and a cushioning system as described above.
Aufgabe der vorliegenden Erfindung ist es daher, das bekannte Dämpfungssystem auch bei Schuhen einzusetzen, bei denen keine dreidimensional verformbare durchtrittsichere Materiallage eingesetzt wird. Insbesondere ist es Aufgabe der vorliegenden Erfindung, das bekannte Dämpfungssystem bei Schuhen mit einer durchtrittsicheren Sohle aus textilem Material einzusetzen.The object of the present invention is therefore to use the known damping system also in shoes in which no three-dimensionally deformable penetration-proof material layer is used. In particular, it is the object of the present invention to use the known damping system in shoes with a penetration-proof sole made of textile material.
Die vorliegende Aufgabe wird gelöst durch eine Sohle geeignet für den Einsatz in einem Sicherheitsschuh, wobei die Sohle einen Zehen-, Mittelfuß- und Fersenabschnitt sowie ein erstes Sohlenelement, das einen Zehen-, Mittelfuß- und Fersenabschnitt aufweist, und ein zweites Sohlenelement, das zumindest einen Fersenabschnitt aufweist, umfasst, wobei das erste Sohlenelement eine durchtrittsichere Sohle ist, die lagenartig oberhalb des zweiten Sohlenelements angeordnet ist und zumindest abschnittsweise mit dem zweiten Sohlenelement verbunden ist, wobei das zweite Sohlenelement eine Aussparung aufweist, in der ein Dämpfungselement angeordnet ist.The present object is achieved by a sole suitable for use in a safety shoe, the sole having a toe, metatarsal and heel section as well as a first sole element, which has a toe, metatarsal and heel section, and a second sole element, which has at least having a heel section, wherein the first sole element is a penetration-proof sole which is arranged in layers above the second sole element and is at least partially connected to the second sole element, the second sole element having a recess in which a cushioning element is arranged.
Bei dieser Lösung ist das Dämpfungselement unterhalb der durchtrittsicheren Sohle angeordnet, so dass keine Eingriffe oder Veränderungen an einer durchtrittsicheren Sohle vorgenommen werden müssen.In this solution, the damping element is arranged below the penetration-resistant sole, so that no interventions or changes have to be made to a penetration-resistant sole.
Wird bei einer bevorzugten Weiterbildung als durchtrittsichere Sohle eine Sohle aus einem textilen Material verwendet, hat dies darüber hinaus den Vorteil, dass die durchtrittsichere Sohle wie eine Brandsohle eingesetzt werden kann. Der Innenaufbau des Schuhs wird hierdurch im Vergleich zu Sicherheitsschuhen mit Metallplatte und Dämpfungssystem deutlich geringer. Für den Träger des Sicherheitsschuhs macht sich dies dadurch bemerkbar, dass der Sicherheitsschuh ein geringeres Gewicht und eine schlankere Form aufweist.If, in a preferred development, a sole made of a textile material is used as the penetration-resistant sole, this has the additional advantage that the penetration-resistant sole can be used like an insole. As a result, the internal structure of the shoe is significantly smaller than that of safety shoes with a metal plate and a cushioning system. For the wearer of the safety shoe, this becomes noticeable in that the safety shoe has a lower weight and a slimmer shape.
Vorzugsweise ist das zweite Sohlenelement aus einem textilen Material oder Leder hergestellt, da dieses Material vergleichsweise einfach zu bearbeiten ist.The second sole element is preferably made of a textile material or leather, since this material is comparatively easy to process.
Um das Dämpfungselement einfach tauschen zu können, wenn es defekt ist oder wenn der Einsatz eines Dämpfungselements mit einem anderen Härtegrad gewünscht ist, ist es von Vorteil, dass das Dämpfungselement lösbar in der Aussparung befestigt ist.In order to be able to easily replace the damping element if it is defective or if the use of a damping element with a different degree of hardness is desired, it is advantageous that the damping element is releasably fastened in the recess.
Für einen sicheren Halt des Dämpfungselements in dem zweiten Sohlenelement ist es von Vorteil, dass das Dämpfungselement, insbesondere der Dämpfungskörper passgenau in der Aussparung befestigt ist.For a secure hold of the damping element in the second sole element, it is advantageous that the damping element, in particular the damping body, is fastened with an accurate fit in the recess.
Zur Erhöhung des Dämpfungseffekts des Dämpfungselements ist es von Vorteil, dass das Dämpfungselement einen Dämpfungskörper mit einer Oberseite, einer Unterseite und Seitenwänden aufweist, wobei der Dämpfungskörper eine Vielzahl von Hohlräumen aufweist, die vorzugsweise zur Unterseite hin offen ausgebildet sind.To increase the damping effect of the damping element, it is advantageous that the damping element has a damping body with an upper side, a lower side and side walls, the damping body having a plurality of cavities, which are preferably designed to be open towards the lower side.
Um zu verhindern, dass das Dämpfungselement durch die Aussparung in dem zweiten Sohlenelement hindurchgleitet, weist das Dämpfungselement einen Dämpfungskörper mit einer Oberseite, einer Unterseite und Seitenwänden auf, wobei das Dämpfungselement an seiner Oberseite über eine Abdeckung verfügt, die zumindest abschnittsweise über die Seitenwände des Dämpfungsköpers hinausragt und vorzugsweise einstückig mit dem Dämpfungskörper ausgebildet ist.In order to prevent the damping element from sliding through the recess in the second sole element, the damping element has a damping body with an upper side, a lower side and side walls, the damping element having a cover on its upper side which at least partially covers the side walls of the damping body protrudes and is preferably formed in one piece with the damping body.
Es hat sich als vorteilhaft herausgestellt, dass die Abdeckung eine gewölbte Oberfläche aufweist, da dies zum einen zu einer Art Luftpolsterschicht zwischen erstem Sohlenelement und zweitem Sohlenelement führt und zum anderen einen punktuellen Massageeffekt bereitstellt, was den Tragekomfort der Sicherheitsschuhe mit dieser Sohle deutlich erhöht.It has been found to be advantageous that the cover has a curved surface, as this leads to a kind of air cushion layer between the first sole element and the second sole element and, on the other hand, provides a selective massage effect, which significantly increases the wearing comfort of the safety shoes with this sole.
Bei einer bevorzugten Ausführungsform weist die Abdeckung eine Lasche auf, um das Dämpfungselement einfach aus der Aussparung herausnehmen und gegen ein anderes ersetzen zu können.In a preferred embodiment, the cover has a tab in order to be able to easily remove the damping element from the recess and replace it with another one.
Es ist weiter bevorzugt, dass das erste Sohlenelement und das zweite Sohlenelement eine Klappe ausbilden. Insbesondere bei der Verwendung einer durchtrittsicheren Sohle aus einem textilen Material besteht die Möglichkeit, an das zweite Sohlenelement zu gelangen, selbst wenn die Sohle in einem Schuh fest eingearbeitet ist, da das erste Sohlenelement klappenartig gegenüber dem zweiten Sohlenelement geschwenkt werden kann.It is further preferred that the first sole element and the second sole element form a flap. In particular when using a penetration-proof sole made of a textile material, there is the possibility of accessing the second sole element, even if the sole is firmly incorporated into a shoe, since the first sole element can be pivoted in a flap-like manner relative to the second sole element.
Bei einer bevorzugten Ausführungsform weist das zweite Sohlenelement eine feste Verbindung in Form einer Verbindungslinie mit dem ersten Sohlenelement auf, wobei die Verbindungslinie vorzugsweise quer zur Längsachse der Sohle verläuft. Hierdurch lässt sich das zweite Sohlenelement fest an dem ersten Sohlenelement befestigten, so dass sich das erste und zweite Sohlenelement nicht gegeneinander verschieben.In a preferred embodiment, the second sole element has a fixed connection in the form of a connecting line to the first sole element, the connecting line preferably running transversely to the longitudinal axis of the sole. This allows the second sole element to be firmly attached to the first sole element, so that the first and second sole elements do not move relative to one another.
Vorzugsweise ist das Dämpfungselement zwischen fersenseitigem Sohlenende und Verbindungslinie angeordnet, wobei auch hier die Verbindungslinie vorzugsweise quer zur Längsachse der Sohle verläuft. Dadurch bildet das erste Sohlenelement im Bereich des Fersenabschnitts zusammen mit dem zweiten Sohlenelement eine Art Klappe. Mit Hilfe dieser Ausführungsform ist es möglich, das Dämpfungselement auch dann noch auszutauschen, selbst wenn die Sohle in einem Schuh fest eingearbeitet, insbesondere mit der Laufsohle fest verbunden ist.The damping element is preferably arranged between the end of the sole on the heel side and the connecting line, the connecting line here also preferably running transversely to the longitudinal axis of the sole. As a result, the first sole element forms a type of flap together with the second sole element in the area of the heel section. With the help of this embodiment it is possible to replace the damping element even if the sole is firmly incorporated into a shoe, in particular is firmly connected to the outsole.
Hierbei ist es von besonderem Vorteil, dass die Verbindungslinie im Bereich des Mittelfußabschnitts vorgesehen ist. Eine Verbindungslinie in diesem Bereich stellt eine ausreichende Öffnung zum Einsetzen oder Austausch des Dämpfungselements in dem zweiten Sohlenelement bereit. Das zweite Sohlenelement kann dadurch kleiner als das erste Sohlenelement ausgebildet werden.It is particularly advantageous here that the connecting line is provided in the area of the metatarsal section. A connecting line in this area provides a sufficient opening for inserting or replacing the cushioning element in the second sole element. The second sole element can thereby be made smaller than the first sole element.
Bei einer bevorzugten Ausführungsform umfasst das zweite Sohlenelement einen ersten Randabschnitt, an dem die Verbindungslinie vorgesehen ist, sowie einen zweiten Randabschnitt, der die gleiche Kontur wie das erste Sohlenelement aufweist. Bei dieser Ausführungsform ist das zweite Sohlenelement vergleichsweise klein ausgebildet, so dass der Platzbedarf des Dämpfungssystems sehr gering ist.In a preferred embodiment, the second sole element comprises a first edge section, on which the connecting line is provided, and a second edge section, which has the same contour as the first sole element. In this embodiment, the second sole element is made comparatively small, so that the space requirement of the damping system is very small.
Gegenstand der vorliegenden Erfindung ist auch ein Sicherheitsschuh, umfassend eine erfindungsgemäße Sohle.The present invention also relates to a safety shoe comprising a sole according to the invention.
Bei einer bevorzugten Ausführungsform umfasst der Sicherheitsschuh eine Laufsohle, die fest mit der Unterseite der Sohle verbunden ist und eine Vertiefung für das Dämpfungselement aufweist, wobei insbesondere die Laufsohle an die Unterseite des Schuhs angeformt oder angeschäumt ist.In a preferred embodiment, the safety shoe comprises an outsole which is firmly connected to the underside of the sole and has a recess for the damping element, the outsole in particular being molded or foamed onto the underside of the shoe.
Zusätzlich oder alternativ kann eine Einlegesohle auf der Sohle vorgesehen sein.Additionally or alternatively, an insole can be provided on the sole.

Das erste Sohlenelement 12 ist eine durchtrittsichere Sohle aus einem textilen Material und lagenartig oberhalb des zweiten Sohlenelements 14 angeordnet. Der Begriff oberhalb bezieht sich hier auf den bestimmungsgemäßen Gebrauch in einem Schuh.The first
Das zweite Sohlenelement 14 besteht ebenfalls aus einem textilen Material. Bezüglich der Durchtrittsicherheit werden keine Anforderungen an das zweite Sohlenelement 14 gestellt. Alternativ kann das zweite Sohlenelement 14 somit auch aus Leder gefertigt sein. Insbesondere eignen sich für das zweite Sohlenelement 14 alle Materialien, die üblicherweise für eine Brandsohle verwendet werden.The second
Das zweite Sohlenelement 14 ist im Mittelfußbereich mit dem ersten Sohlenelement 12 fest verbunden. Insbesondere ist das zweite Sohlenelement 14 mit dem ersten Sohlenelement 12 unter Ausbildung einer Verbindungslinie 16 vernäht. Alternativ kann das zweite Sohlenelement 14 unter Ausbildung einer Verbindungslinie an dem ersten Sohlenelement 12 angeklebt sein.The second
Das zweite Sohlenelement 14 umfasst einen ersten Randabschnitt 20, an dem die Verbindungslinie 16 vorgesehen ist, sowie einen zweiten Randabschnitt 22, der die gleiche Kontur und Größe wie das erste Sohlenelement 12 aufweist. Das zweite Sohlenelement 14 ist so an dem ersten Sohlenelement 12 befestigt, dass der zweite Randabschnitt 22 des zweiten Sohlenelements 14 deckungsgleich mit dem entsprechenden Randabschnitt des ersten Sohlenelements 12 ist.The second
Die Verbindungslinie 16 ist eine gerade Linie, verläuft im Wesentlichen quer zur Längsachse der Sohle 10 und erstreckt sich von einer Längsseite der Sohle 10 zur entgegengesetzt liegenden Längsseite der Sohle 10, so dass das erste Sohlenelement 12 im Fersenbereich klappenartig auf dem zweiten Sohlenelement 14 angeordnet ist.The connecting
In dem zweiten Sohlenelement 14 ist im Fersenbereich eine Aussparung 24 vorgesehen, in der ein Dämpfungselement 26 aus einem elastischen, gummiartigen Kunststoffmaterial angeordnet ist. Das Dämpfungselement 26 weist einen vorgegebenen Härtegrad auf.In the second
Wie insbesondere in den
Der Dämpfungskörper 28 ist im Querschnitt passgenau zur Aussparung 24 geformt und wird in der Aussparung 24 fest gehalten. Die Außenseite der Seitenwände 29 entspricht somit der Größe der Aussparung 24, wobei die Seitenwände 29 leicht konisch zulaufen und der Durchmesser des Dämpfungskörpers 28 im Bereich der Abdeckung 30 etwas größer als im Bereich der Unterseite ist.The cross section of the damping
Die Abdeckung 30 ist nach außen gewölbt ausgebildet und verfügt an ihrem seitlichen Rand über eine Lasche 32.The
Wie in
In einem Zustand, in dem das Dämpfungselement 26 sich in dem zweiten Sohlenelement 14 befindet, liegt die Abdeckung 30 mit ihrer Unterseite auf dem zweiten Sohlenelement 14 auf. Die Abdeckung 30 befindet sich hierbei zwischen dem ersten Sohlenelement 12 und dem zweiten Sohlenelement 14. Der Dämpfungskörper 28 ist in der Aussparung 24 des zweiten Sohlenelements 14 angeordnet und ragt nach außen bzw. unten aus dem zweiten Sohlenelement 14 heraus.In a state in which the damping
Das Dämpfungselement 26 ist lösbar in der Aussparung 24 des zweiten Sohlenelements 14 gehalten, so dass defekte Dämpfungselemente 26 ausgetauscht werden können oder Dämpfungselemente verschiedener Härtegrade in der Aussparung 24 des zweiten Sohlenelements 14 eingesetzt werden können.The damping
Das Dämpfungselement 26 muss somit einerseits sicher in der Aussparung 24 gehalten werden. Dies wird dadurch erreicht, dass die Abdeckung 30 seitlich über den Dämpfungskörper 28 hinausragt. Insbesondere wird dadurch verhindert, dass das Dämpfungselement 26 versehentlich durch die Aussparung 24 hindurchgedrückt wird. Um das Dämpfungselement 26 andererseits wieder aus der Aussparung 24 entfernen zu können, ist die Lasche 32 vorgesehen, mit deren Hilfe ein Nutzer das Dämpfungselement 26 aus der Aussparung 24 herausziehen kann.The damping
Bei einer nicht dargestellten Ausführungsform, bei der das Dämpfungselement nicht austauschbar ist, können anstelle der Abdeckung oder zusätzlich zur Abdeckung auch Rastelemente vorgesehen sein, die den Dämpfungskörper sicher in der Aussparung halten.In an embodiment not shown, in which the damping element is not exchangeable, latching elements can also be provided instead of the cover or in addition to the cover, which hold the damping body securely in the recess.

Um das Dämpfungselement 28 in den fertiggestellten Schuh einzusetzen bzw. zu einem späteren Zeitpunkt auszutauschen, wird die Einlegesohle 52 entfernt und dann der Fersenabschnitt des ersten Sohlenelements 12 angehoben, so dass das zweite Sohlenelement 14 mit dem Dämpfungselement 26 frei zugänglich ist. Das Dämpfungselement 26 kann dann mittels der Lasche 32 entnommen werden. Anschließend kann das gewünschte neue Dämpfungselement 26 eingesetzt werden.In order to insert the
Im Rahmen der Erfindung ist es nicht zwingend notwendig, dass die Verbindungslinie im Bereich des Mittelfußabschnitts vorgesehen ist und sich im Wesentlichen quer zur Längsachse der Sohle erstreckt.In the context of the invention, it is not absolutely necessary for the connecting line to be provided in the area of the metatarsal section and to extend essentially transversely to the longitudinal axis of the sole.
Alternativ kann die Verbindungslinie an jeder Stelle des zweiten Sohlenelements 12 verlaufen. Die Verbindunglinie kann auch am seitlichen Randabschnitt, der deckungsgleich mit dem ersten Sohlenelement ist, ausgebildet sein. Es ist hierbei bevorzugt, dass der Randabschnitt des zweiten Sohlenelements nur abschnittsweise mit dem ersten Sohlenelement verbunden ist, um eine klappenartige Verbindung zwischen dem ersten Sohlenelement und dem zweiten Sohlenelement zu erhalten.Alternatively, the connecting line can run at any point on the second
Es ist nicht notwendig, dass sich das zweite Sohlenelement bis in den Bereich des Mittelfußes erstreckt. Es ist ausreichend, wenn das zweite Sohlenelement den Fersenabschnitt bedeckt.It is not necessary for the second sole element to extend into the area of the metatarsus. It is sufficient if the second sole element covers the heel portion.
Bei einer nicht dargestellten Ausführungsform weist das zweite Sohlenelement die Kontur des ersten Sohlenelements auf. Die Verbindungslinie, an der das zweite Sohlenelement mit dem ersten Sohlenelement verbunden ist, kann sowohl am äußeren Rand des zweiten Sohlenelements als auch quer oder schräg zur Längsachse der Sohle im Mittelfuß- und/oder Vorderfußbereich bzw. außerhalb der Aussparung vorgesehen sein.In an embodiment not shown, the second sole element has the contour of the first sole element. The connection line on which the second sole element is connected to the first sole element can be provided both on the outer edge of the second sole element and transversely or obliquely to the longitudinal axis of the sole in the metatarsal and / or forefoot area or outside the recess.
Bei all den dargestellten Ausführungsformen ist die Kontur des zweiten Sohlenelements im Wesentlichen frei wählbar. Die Forderung an das zweite Sohlenelement besteht im Wesentlichen darin, das Dämpfungselement aufzunehmen und mit dem ersten Sohlenelement eine klappenartige Verbindung auszubilden.In all of the illustrated embodiments, the contour of the second sole element is essentially freely selectable. The requirement of the second sole element consists essentially in receiving the damping element and forming a flap-like connection with the first sole element.
Die Merkmale der dargestellten Ausführungsformen können untereinander kombiniert werden, wobei einzelne Merkmal auch weggelassen werden können.The features of the illustrated embodiments can be combined with one another, with individual features also being able to be omitted.
