Description

Diese Erfindung betrifft ein Feder- und Dämpfungselement anordenbar in oder benachbart zu einem Schuh umfassend erste Magnete mitsamt einem ersten Befestigungselement zum Anbringen der ersten Magnete an einem ersten Teilbereich des Schuhs, zweite Magnete mitsamt einem zweiten Befestigungselement zum Anbringen der zweiten Magnete an einem zweiten Teilbereich des Schuhs oder benachbart zum Schuh, wobei zumindest ein erster Magnet verschieblich zu zumindest einem zweiten Magneten gelagert ist.This invention relates to a spring and damping element locatable in or adjacent to a shoe comprising first magnets together with a first fastening element for attaching the first magnets to a first portion of the shoe, second magnets together with a second fastening element for attaching the second magnets to a second portion of the Shoe or adjacent to the shoe, wherein at least a first magnet is slidably mounted to at least a second magnet.

Feder- und Dämpfungselemente in Schuhen funktionieren nach dem Prinzip der Abstoßung zweier gleich gepolter Einzelmagnete bei hinreichend naher Annäherung der Einzelmagnete. Die Abstoßungskraft ist bei Anordnung der Magnete nach dem Stand der Technik abhängig vom Abstand der ersten Magnete und zweiten Magnete.Spring and damping elements in shoes function on the principle of repulsion of two identically polarized individual magnets with sufficiently close approximation of the individual magnets. The repulsive force is in the arrangement of the magnets according to the prior art depends on the distance of the first magnets and second magnets.

US7694440B1 offenbart ein Feder- und Dämpfungselement umfassend zwei Magnete für einen Schuh. Im Unterschied zu der im Folgenden offenbarten Erfindung sind die Einzelmagnete nicht nach dem Halbach-Array-Effekt angeordnet. US7694440B1 discloses a spring and damping element comprising two magnets for a shoe. In contrast to the invention disclosed below, the individual magnets are not arranged according to the Halbach array effect.

US20100011616 beschreibt ebenso die Verwendung eines Magneten umfassend Einzelmagnete als ein Feder- und Dämpfungselement eines Schuhs. Es ist ebenso in US20100011616 kein Hinweis auf eine spezielle Anordnung der Einzelmagnete gemäß Halbbach-Array zu finden. US20100011616 also describes the use of a magnet comprising individual magnets as a spring and damping element of a shoe. It is also in US20100011616 no indication to find a special arrangement of the individual magnets according Halbbach array.

Die im Folgenden diskutierte Erfindung stellt sich die Aufgabe der Verwendung von Magneten als ein Feder- und Dämpfungselement in einem Schuh, wobei die Wirkungsweise der Magnete durch eine spezielle Anordnung der Magnete optimal ausgenützt werden soll, um die Anzahl der notwendigen Magnete zu minimieren.The invention discussed below sets itself the task of using magnets as a spring and damping element in a shoe, wherein the operation of the magnets should be optimally utilized by a special arrangement of the magnets in order to minimize the number of magnets required.

Magnete weisen nach dem Stand der Technik ein hohes Gewicht auf, was einem Einsatz in einem Schuh, insbesondere einem Sportschuh entgegenstehen würde.Magnets according to the prior art, a high weight, which would oppose an insert in a shoe, in particular a sports shoe.

Die Anordnung von Magneten in einem Schuh kann auch den Effekt haben, dass metallische Gegenstände, welche beispielsweise auf einem Boden liegen, durch den im Schuh befindlichen Magneten angezogen werden.The arrangement of magnets in a shoe can also have the effect that metallic objects, which are for example on a floor, are attracted by the magnet in the shoe.

Die im Folgenden offenbarte Erfindung überwindet diese Nachteile.The invention disclosed below overcomes these disadvantages.

Ein erfindungsgemäßes Feder- und Dämpfungselement zeichnet sich dadurch aus, dass die ersten Magnete und die zweiten Magnete nach dem Halbach-Array-Prinzip angeordnet sind.An inventive spring and damping element is characterized in that the first magnets and the second magnets are arranged according to the Halbach array principle.

Die Anordnung von Einzelmagneten eines ersten Magneten und eines zweiten Magneten ist beispielsweise in J.E. Hilton, S.M. McMurry, An adjustable linear Halbach array, Journal of Magnetism and Magnete Materials, 324(2012), Seiten 2051-2056 beschreiben. Es wird weiters verwiesen auf K. Halbach, Design of permanent multipole magnets with oriented rare earth coblat material, Nuclear istruments and methods 169 (1980) 1-10 und J.C. Mallinson, One-side fluxes - a magnetic curiosity?, IEEE transactions on magnetics, Vol. mag-9, No. 4, December 1973 . Eine Anordnung nach Halbach-Array hat den Effekt, dass das Magnetfeld auf den Bereich zwischen den ersten und zweiten Magneten gebündelt wird. Dies ist für die erfindungsgemäße Aufgabe insofern vorteilhaft, als dass die Anzahl der ersten Magnete und zweiten Magnete im Vergleich zu den Vorrichtungen nach dem Stand der Technik reduziert werden kann. Durch die Bündelung der Magnetfelder entfällt der Nachteil des Anziehens von metallischen Gegenständen an die im Schuh angeordneten Magnete. Die Bündelung der Magnetfelder ist im Rahmen der Offenbarung dieser Erfindung so zu verstehen, dass ein Bereich mit einem verstärktem Magnetfluss (im Inneren der Schuhsole) und ein weiterer Bereich mit einem abgeschwächten Magnetfluss (im Außenbereich zu der Schuhsole) geschaffen wird.The arrangement of individual magnets of a first magnet and a second magnet is, for example, in FIG JE Hilton, SM McMurry, An adjustable linear Halbach array, Journal of Magnetism and Magnets Materials, 324 (2012), pp. 2051-2056 describe. It is further referred to K. Halbach, Design of permanent multipole magnets with oriented rare earth coblat material, Nuclear istruments and methods 169 (1980) 1-10 and JC Mallinson, One-side fluxes - a magnetic curiosity ?, IEEE transactions on magnetics, Vol. Mag-9, no. 4, December 1973 , A Halbach array arrangement has the effect of focusing the magnetic field on the area between the first and second magnets. This is advantageous for the object according to the invention in that the number of first magnets and second magnets can be reduced in comparison with the devices according to the prior art. The bundling of the magnetic fields eliminates the disadvantage of attracting metallic objects to the magnets arranged in the shoe. The bundling of the magnetic fields is to be understood within the scope of the disclosure of this invention as providing an area with an increased magnetic flux (inside the shoe brine) and another area with an attenuated magnetic flux (outside the shoe brine).

Die Abstoßungskraft zwischen dem ersten Magneten und dem zweiten Magneten wird durch die Anordnung gemäß Halbach-Array vorteilhaft beeinflusst, da das Magnetfeld gebündelt ist.The repulsive force between the first magnet and the second magnet is favorably influenced by the arrangement according to the Halbach array because the magnetic field is focused.

Das erfindungsgemäße Element kann so aufgebaut sein, dass jeweils ein erster Magnet und ein zweiter Magnet in einer Achse ausgerichtet sind, welche Achse im Wesentlichen parallel zu einer Belastungsachse einer Teilbelastung gerichtet ist. Vorzugsweise sind der erste Magnet und der zweite Magnet senkrecht zu der Achse ausgerichtet.The element according to the invention can be constructed so that in each case a first magnet and a second magnet are aligned in an axis, which axis is directed substantially parallel to a loading axis of a partial load. Preferably, the first magnet and the second magnet are aligned perpendicular to the axis.

Ein solcher Aufbau ist vor allem bei einer einheitlichen Belastung und einer daraus resultierenden Belastungsrichtung vorteilhaft.Such a construction is advantageous above all with a uniform load and a resulting load direction.

Die Oberflächen der ersten Magnete und die Oberflächen der zweiten Magnete können eine polygonale, kongurente Formen aufweisen, sodass die ersten Magnete und die zweiten Magnete bei einer relativen Verschiebung zueinander Abstoßungskräfte - in Abhängigkeit von den Oberflächen der Magnete - in mehrere Richtungen generieren können.The surfaces of the first magnets and the surfaces of the second magnets may have a polygonal, conformational shape so that the first magnets and the second magnets can generate repulsive forces in a plurality of directions relative to each other at a relative displacement to each other, depending on the surfaces of the magnets.

Die ersten Magnete mitsamt dem ersten Befestigungselement und/oder die zweiten Magnete mitsamt dem zweiten Befestigungselement können lösbar am Schuh angebracht sein. Die Befestigungselemente können mittels Verbindungsmitteln nach dem Stand der Technik wie beispielsweise eine Steck- und/oder Schraubverbindung am Schuh angebracht sein.The first magnets together with the first fastening element and / or the second magnets together with the second fastening element can be releasably attached to the shoe. The fastening elements can be attached by means of connecting means according to the prior art such as a plug and / or screw on the shoe.

Das erste Befestigungselement und/oder das zweite Befestigungselement kann eine Klebeschicht sein.The first fastening element and / or the second fastening element may be an adhesive layer.

Vorteilhaft ist das Feder- und Dämpfungselement modulartig aufgebaut, sodass ein in einem Schuh befindliches Feder- und Dämpfungselement durch den Benutzer leicht durch ein anderes Feder-und Dämpfungselement ausgetauscht werden kann. Die lösbare Anbringung des Feder- und Dämpfungselementes erfolgt beispielsweise nach mechanischen Verbindungsmethoden nach dem Stand der Technik.Advantageously, the spring and damping element is constructed modular, so that a befindliches in a shoe spring and damping element can be easily replaced by the user by another spring and damping element. The releasable attachment of the spring and damping element takes place, for example, according to mechanical connection methods according to the prior art.

Ein Teilbereich des Schuhs, in welchem das erfindungsgemäße Element angeordnet ist, kann beispielsweise eine Einlage sein.A portion of the shoe in which the element according to the invention is arranged may, for example, be an insert.

Der Schuh kann ein Sportschuh wie beispielsweise ein Laufschuh, Schischuh oder Langlaufschuh sein.The shoe may be a sports shoe such as a running shoe, ski boot or cross country boot.

Die Erfindung schließt nicht aus, dass die ersten Magnete in einem Teilbereich des Schuhs, die zweiten Magnete in einem zu dem Schuh benachbarten Bereich angeordnet sind. Beispielsweise können die ersten Magnete im Sohlenbereich eines Langlaufschuhs, die zweiten Magnete in einem zum Schuh benachbarten Bereich wie beispielsweise einer Aufstandsfläche der Bindung am Ski angeordnet sein. Der hier beispielhaft beschriebene zum Schuh benachbart angeordnete Bereich steht in einem funktionellen Zusammenhang mit dem Schuh.The invention does not exclude that the first magnets in a portion of the shoe, the second magnets are arranged in a region adjacent to the shoe. For example, the first magnets in the sole region of a cross country boot, the second magnets in a region adjacent to the shoe, such as a footprint of the binding on the ski can be arranged. The area described here by way of example adjacent to the shoe is in a functional relationship with the shoe.

Das erfindungsgemäße Element kann auch in einer Vorrichtung zur Anpassung des Schuhs an den Fuß des Benutzers wie beispielsweise einer Schnalle eines Schischuhs angeordnet sein. Durch die Anordnung des Elementes kann die Spannkraft der Schnalle begrenzt werden.The element according to the invention can also be arranged in a device for adapting the shoe to the foot of the user, such as a buckle of a ski boot.

Das erfindungsgemäße Element kann sowohl zum Federn und Dämpfen von vertikalen als auch horizontalen Belastungen im Sohlenbereich eines Schuhs angeordnet sein. Vertikale Kräfte können beispielsweise durch das Eigengewicht des Benutzers oder durch den Bewegungsgang des Benutzers hervorgerufen werden. Horizontale Belastungen entstehen beim Beschleunigen oder Bremsen des Benutzers.The element according to the invention can be arranged both for springing and damping vertical as well as horizontal loads in the sole region of a shoe. Vertical forces can be caused, for example, by the weight of the user or by the movement of the user. Horizontal loads occur when the user accelerates or brakes.

Die hier offenbarte Erfindung stellt sich die Aufgabe, die Belastung auf den Benutzer, insbesondere dessen Gelenke zu reduzieren.The invention disclosed herein has as its object to reduce the burden on the user, in particular its joints.

Ein Schaft eines Schuhs erfährt beim Tragen des Schuhs durch den Benutzer Dehnungen. Diese Dehnungen können beispielsweise durch eine Verformung des Fußes, durch den Vorgang des Abrollens während des Gehens begründet sein. Eine weitere Verwendung des erfindungsgemäßen Elementes kann sich dadurch auszeichnen, dass die ersten Magnete in einem ersten Schaftteilbereich und die zweiten Magnete in einem zweiten Schaftteilbereich des Schuhs angeordnet sind.A shaft of a shoe undergoes stretching as the user wears the shoe. These strains may be due, for example, to a deformation of the foot, to the rolling process during walking. Another use of the invention Element may be characterized in that the first magnets are arranged in a first shaft portion and the second magnets in a second shaft portion of the shoe.

Die ersten Magnete und/oder die zweiten Magnete können Einzelmagnete mit unterschiedlichen Feldstärken aufweisen. Durch die unterschiedlichen Feldstärken werden Zonen mit unterschiedlichen Federungs- und Dämpfungseigenschaften im erfindungsgemäßen Element geschaffen.The first magnets and / or the second magnets may have individual magnets with different field strengths. Due to the different field strengths zones are created with different suspension and damping properties in the element according to the invention.

Die ersten Magnete und die zweiten Magnete können Einzelmagnete mit jeweils gleicher Polung umfassen.The first magnets and the second magnets may comprise individual magnets each having the same polarity.

Die ersten Magnete und die zweiten Magnete können Einzelmagnete mit jeweils unterschiedlicher Polung umfassen, wobei ein Einzelmagnet der ersten Magnete und ein Einzelmagnet der zweiten Magnete, welche Einzelmagnete unterschiedlich gepolt sind, gegenüberliegend angeordnet sind.The first magnets and the second magnets may comprise individual magnets, each having a different polarity, wherein a single magnet of the first magnets and a single magnet of the second magnets, which individual magnets are differently poled, are arranged opposite one another.

Die Anordnung der Einzelmagnete hat so zu erfolgen, dass Einzelmagnete mit gleicher Polung gegenüberliegend angeordnet sind, sodass durch das Magnetfeld eine Abstoßungskraft geschaffen wird.The arrangement of the individual magnets has to be done so that individual magnets are arranged opposite each other with the same polarity, so that a repulsive force is created by the magnetic field.

Das erste Befestigungselement und das zweite Befestigungselement können zueinander entlang einer polygonalen Bewegungslinie verschieblich gelagert sein.The first fastening element and the second fastening element can be displaceably mounted to each other along a polygonal line of movement.

Das erste Befestigungselement und das zweite Befestigungselement können zueinander drehbar um einen Punkt oder eine Achse gelagert sein.The first attachment member and the second attachment member may be rotatably supported to each other about a point or an axis.

The possible movement of the first magnets relative to the second magnets should be substantially parallel to the loading direction.

Die Bewegung des ersten Magneten relativ zum zweiten Magneten kann - auch in Kombination mit Gelenken - durch Führungselemente und/oder durch eine mögliche Deformationsrichtung des Schuhs vorgegeben werden. Eine mögliche Deformationsrichtung des Schuhs kann durch bestimmte Eigenschaften der verwendeten Materialien, durch eine Kombination von Materialien definiert werden. Beispielsweise kann eine mögliche Deformationsrichtung eines Schuhs durch eine Kombination eines allseitig dehnbaren Materials mit einem Bewehrungselement erreicht werden.The movement of the first magnet relative to the second magnet can be predetermined - also in combination with joints - by guide elements and / or by a possible deformation direction of the shoe.
