Description

Vorrichtung zur Schrittweitenvariierung Ā Device for step size variation
Die vorliegende Erfindung betrifft eine Vorrichtung zur UnterstĆ¼tzung der Fortbe- wegung eines Benutzers, insbesondere zur Schrittweitenvariierung, mit einem Re- servoir, einem Ɯbertragungsbereich und einer Kammer. The present invention relates to a device for supporting the movement of a user, in particular for varying the step size, with a reservoir, a transmission area and a chamber.
Die Erfindung betrifft ferner einen Schuh mit zumindest einem Obermaterial und einer Sohle und zumindest einer erfindungsgemƤƟen Vorrichtung. The invention further relates to a shoe with at least one upper material and a sole and at least one device according to the invention.
Bei der Entwicklung von Schuhen wird besonders im Laufsportbereich immer mehr Wert darauf gelegt, die FuƟbelastung, das Abrollverhalten des FuƟes sowie die Performance des Schuhs zu optimieren. DafĆ¼r werden entsprechende Materia- lien und Verfahren fĆ¼r die Herstellung der Sohlen und Obermaterialien der Schuhe ausgewƤhlt. In the development of shoes, in particular in the field of running sports, more and more value is placed on optimizing the foot load, the rolling behavior of the foot and the performance of the shoe. Appropriate materials and processes for the production of the soles and upper materials of the shoes are selected for this.
Beispielsweise gibt es Kunststoffsysteme fĆ¼r Schuhsohlen, die derart ausgebildet sind, dass sie eine maximale EnergierĆ¼ckgewinnung fĆ¼r den TrƤger der Schuhe gewƤhrleisten. Ebenso gibt es Sportschuhe, die RĆ¼ckstellfedern oder Ƥhnliches in der Sohle aufweisen, die dazu ausgebildet sind, die ReaktionsfƤhigkeit und Ener- gierĆ¼ckgabe des Schuhs zu verbessern. Zum selben Zweck werden auch Schuhe mit besonders harten und flachen Sohlen hergestellt, um einen direkteren Boden- kontakt und damit Schnelligkeit fĆ¼r den LƤufer zu erreichen. For example, there are plastic systems for shoe soles that are designed in such a way that they ensure maximum energy recovery for the wearer of the shoes. There are also sports shoes that have return springs or the like in the sole, which are designed to improve the responsiveness and energy return of the shoe. Shoes with particularly hard and flat soles are also produced for the same purpose in order to achieve more direct ground contact and therefore speed for the runner.
Andere Systeme die in den Sohlen der Schuhe vorgesehen sind, sind hingegen derart ausgebildet, dass sie mehr DƤmpfung fĆ¼r die FĆ¼ĆŸe der LƤufer gewƤhrleis- ten und damit einen verbesserten Komfort bieten kƶnnen. Die oben aufgelisteten Systeme haben prinzipiell alle die Funktion, die beim Lau- fen natĆ¼rlich auftretenden StĆ¶ĆŸe abzufedern und mƶglichst viel der Energie an den LƤufer zurĆ¼ckzugeben. Die Schuhsohle dient dabei als DƤmpfungsmittel und de- formiert sich bei jedem Schritt je nach ElastizitƤt der Sohle mehr oder weniger. Nachdem der LƤufer den FuƟ wieder abhebt, ist die Sohle derart konzipiert, dass sie idealerweise die Form des nicht belasteten Ausgangszustandes vollstƤndig wieder einnimmt. Die Beschleunigung des LƤufers sowie das Laufverhalten LƤu- fers sollen durch die RĆ¼ckstellkraft der Sohle unterstĆ¼tzt werden. Other systems that are provided in the soles of the shoes, on the other hand, are designed in such a way that they provide more cushioning for the feet of the runners and can therefore offer improved comfort. In principle, the systems listed above all have the function of cushioning the shocks that naturally occur during running and returning as much energy as possible to the runner. The shoe sole serves as a damping agent and deforms more or less with each step depending on the elasticity of the sole. After the runner lifts the foot again, the sole is designed in such a way that it ideally takes on the shape of the unloaded initial state again. The acceleration of the runner and the running behavior of the runner should be supported by the restoring force of the sole.
Die Aufgabe der vorliegenden Erfindung ist es einen Schuh bereitzustellen, der die EnergierĆ¼ckgewinnung bei der Fortbewegung eines Benutzers verbessert. Es ist eine weitere Aufgabe der vorliegenden Erfindung einen Schuh bereitzustellen, der es ermƶglicht die Laufleistung eines Benutzers derart zu beeinflussen, dass dieser bspw. im Wettkampf eine bessere Leistung erzielen kann. Es ist eine weitere Auf- gabe der vorliegenden Erfindung einen kostengĆ¼nstigen Trainingsschuh bereitzu- stellen. The object of the present invention is to provide a shoe which improves the energy recovery during the movement of a user. It is a further object of the present invention to provide a shoe which makes it possible to influence the mileage of a user in such a way that, for example, he can achieve better performance in competition. It is a further object of the present invention to provide an inexpensive training shoe.
Diese Aufgabe wird durch eine Vorrichtung zur UnterstĆ¼tzung der Fortbewegung eines Benutzers mit den Merkmalen des Anspruchs 1 , sowie durch einen Schuh mit den Merkmalen des Anspruchs 21 gelƶst. This object is achieved by a device for supporting the movement of a user with the features of claim 1 and by a shoe with the features of claim 21.
Die erfindungsgemƤƟe Vorrichtung zur UnterstĆ¼tzung der Fortbewegung eines Benutzers, insbesondere zur Schrittweitenvariierung, mit einem Reservoir, einem Ɯbertragungsbereich und einer Kammer, zeichnet sich dadurch aus, dass das Re- servoir dazu ausgebildet ist, mit Druck beaufschlagt zu werden und der Ɯbertra- gungsbereich dazu ausgebildet ist, eine von dem Reservoir ausgehende Druck- welle in die Kammer zu Ć¼bertragen. Beim Lƶsen der Beaufschlagung wird ein Un- terdruck im Reservoir erzeugt und damit der gegenteilige Effekt erzielt. Die Vorrichtung basiert somit auf dem Prinzip der Ɯbertragung von Druckwellen. Dabei wird durch das Beaufschlagen des Reservoirs mit Druck eine Druckwelle erzeugt, die Ć¼ber den Ɯbertragungsbereich in Richtung der Kammer transportiert wird und sich damit entlang der Vorrichtung bewegt bis sie an ein Ende der Vor- richtung stĆ¶ĆŸt. Nach Beendigung der Beaufschlagung bildet sich im Reservoir ein UnterdrĆ¼ck, wodurch der gegenteilige Effekt erzielt wird. Damit wird eine Druck- welle in Richtung des Reservoirs bewegt und somit gewissermaƟen ein Sog er- zeugt mittels dem ein auf die Kammer ausgeĆ¼bter Druck wieder entfernt werden kann. Die Bewegung der Druckwelle geschieht dabei hauptsƤchlich in der The device according to the invention for supporting the movement of a user, in particular for varying the step size, with a reservoir, a transmission area and a chamber, is characterized in that the reservoir is designed to be pressurized and the transmission area is designed for this is to transmit a pressure wave emanating from the reservoir into the chamber. When the pressure is released, a negative pressure is created in the reservoir and the opposite effect is achieved. The device is thus based on the principle of the transmission of pressure waves. By applying pressure to the reservoir, a pressure wave is generated which is transported across the transmission area in the direction of the chamber and thus moves along the device until it hits one end of the device. After the application has ended, a depression is formed in the reservoir, as a result of which the opposite effect is achieved. A pressure wave is thus moved in the direction of the reservoir and thus, to a certain extent, a suction is generated by means of which a pressure exerted on the chamber can be removed again. The movement of the pressure wave occurs mainly in the
Sagittalebene des Benutzers. Sagittal plane of the user.
Je nach Richtung der Druckwelle in oder entgegen einer Laufrichtung des Benut- zers kann eine Schrittweite eines Benutzers somit gezielt verlƤngert oder verkĆ¼rzt werden. Beispielsweise kann durch eine Druckwelle, die in Laufrichtung betrachtet nach hinten und oben gerichtet ist, der Fersenhub eines LƤufers unterstĆ¼tzt wer- den, wƤhrend eine Druckwelle, die zum Zeitpunkt der Schwingung der Ferse in Richtung GesƤƟ den Abdruck des FuƟes behindert, die Laufbewegung dadurch gezielt erschwert. Durch eine gezielte Variierung der Schrittweite kann bspw. zu Trainingszwecken die Schrittweite eines Benutzers verkĆ¼rzt werden, um die Belas- tung im Training zu erhƶhen. Umgekehrt kann dann bspw. im Wettkampf die Aus- richtung der Vorrichtung derart gewƤhlt werden, dass eine Schrittweite verlƤngert wird, sodass der Benutzer fĆ¼r die gleiche Distanz weniger Schritte benƶtigt. Depending on the direction of the pressure wave in or against a running direction of the user, a step size of a user can thus be lengthened or shortened in a targeted manner. For example, a heel stroke of a runner can be supported by a pressure wave, which is directed backwards and upwards when viewed in the direction of travel, while a pressure wave, which hinders the footprint at the time of the heel vibrating in the direction of the buttocks, specifically targets the running movement difficult. By deliberately varying the step size, the step size of a user can be shortened, for example for training purposes, in order to increase the load during the training. Conversely, the alignment of the device can then be selected, for example in competition, in such a way that an increment is extended so that the user requires fewer steps for the same distance.
GemƤƟ einer AusfĆ¼hrungsform weist die Kammer einen Hohlraum auf, wobei der Hohlraum zumindest eine bewegliche Masse enthƤlt. Somit trifft die im Reservoir erzeugte Druckwelle in der Kammer auf die bewegliche Masse, versetzt diese dadurch in Bewegung und verlagert dabei die Position der beweglichen Masse im Hohlraum. Dies geschieht in Relation zu den Bodenkontakt- bzw. Flugphasen des Benutzers. Beim Bewegen und StoƟen der beweglichen Masse zu bzw. an einem der zwei Enden des Hohlraums wird kinetische Energie in potentielle Energie um- gewandelt. Beim Aufprall der beweglichen Masse am Ende der Vorrichtung wird diese Energie dann als kinetische Energie wieder freigegeben. Bei Beendigung der Beaufschlagung des Reservoirs mit Druck erzeugt das Reservoir den gegen- teiligen Effekt und zieht die bewegliche Masse zurĆ¼ck in Richtung Reservoir und hƤlt sie durch den erzeugten Sog dort zunƤchst fest. Der Sog muss demnach so groƟ sein, dass die Masse am entsprechenden Ende der Kammer gehalten wird, auch wenn der FuƟ des Benutzer derart geneigt ist, dass das Kopfende der Kam- mer vom Kƶrper weg - also nach unten - zeigt. Dies entspricht jener Schrittphase, in der sich der FuƟ des LƤufers in Laufrichtung betrachtet hinter (dorsal) dem Kƶr- perschwerpunkt befindet. Die Zehen des entsprechenden FuƟes zeigen dann in der Regel nach hinten in Richtung Boden. Die Bewegung in Richtung Reservoir der beweglichen Masse geschieht wƤhrend des Abhebens des FuƟes des Benut- zers. Bei der anschlieƟenden Flugphase bzw. der Schwungphase des FuƟes wird die bewegliche Masse wieder von dem dorsalen Ende der Kammer an das gegen- Ć¼berliegende Kopfende geschleudert bis sie an das Kopfende der Kammer stĆ¶ĆŸt. Dies geschieht wƤhrend der letzten Phase des Schwunges des FuƟes, bei der der FuƟ Ć¼ber den Kƶrperschwerpunkt hinaus nach vorne geschwungen wird und sich der andere FuƟ des LƤufers bereits wieder auf dem Bodenkontakt aufweist. According to one embodiment, the chamber has a cavity, the cavity containing at least one movable mass. Thus, the pressure wave generated in the reservoir hits the movable mass in the chamber, sets it in motion and thereby displaces the position of the movable mass in the cavity. This happens in relation to the ground contact or flight phases of the user. When moving and pushing the moving mass towards or at one of the two ends of the cavity, kinetic energy is converted into potential energy. changed. When the moving mass hits the end of the device, this energy is then released again as kinetic energy. When the application of pressure to the reservoir ends, the reservoir produces the opposite effect and pulls the movable mass back towards the reservoir and initially holds it there due to the suction generated. The suction must therefore be so large that the mass is held at the corresponding end of the chamber, even if the user's foot is inclined so that the head end of the chamber points away from the body - ie downwards. This corresponds to the step phase in which the runner's foot, viewed in the running direction, is behind (dorsal) the center of gravity. The toes of the corresponding foot usually point backwards towards the floor. The movement in the direction of the reservoir of the movable mass takes place during the lifting of the user's foot. During the subsequent flight phase or the swing phase of the foot, the moveable mass is again thrown from the dorsal end of the chamber to the opposite head end until it hits the head end of the chamber. This happens during the last phase of the swing of the foot, in which the foot is swung forward beyond the center of gravity and the other foot of the runner is already in contact with the ground.
Die somit freigegebene Energie kann dann zu einem dynamischeren, gegebenen- falls auch lƤngeren Schritt beitragen. Durch das Beaufschlagen bzw. das an- schlieƟende Lƶsen des Reservoirs mit Druck, kann die Bewegung der bewegli- chen Masse gezielt gesteuert werden. The energy released in this way can then contribute to a more dynamic, possibly longer step. The movement of the moving mass can be controlled in a targeted manner by applying pressure or subsequently releasing the reservoir with pressure.
Dadurch kann es einerseits erreicht werden, dass sich die bewegliche Masse vor der Bewegungsphase des FuƟes in Laufrichtung hinten befindet. In diesem Mo- ment stĆ¶ĆŸt die Masse an das dorsale Ende der Kammer und unterstĆ¼zt die Bewe- gung nach hinten und oben. Daher ist ein energetischer Effekt in dorsokranialer Richtung zu erwarten. Andererseits kann es auch erreicht werden, dass die Masse zunƤchst an das vent- rale Ende der Kammer bewegt wird, was wƤhrend des Bodenkontakts des FuƟes zunƤchst keine Auswirkungen hat. AnschlieƟend wird die Masse aufgrund des erzeugten Sogs nach Beendigung des Bodenkontakts in Richtung dorsales Ende bewegt und dort gehalten bis der FuƟ in die Schwungphase Ć¼bergeht, wƤhrend der die Masse dann den Sog Ć¼berwindet bzw. der Sog endet und die Masse ma- ximal weit nach vorne geschleudert wird. In this way, it can be achieved, on the one hand, that the movable mass is in the back in the running direction before the movement phase of the foot. At this moment, the mass hits the dorsal end of the chamber and supports the movement back and up. Therefore an energetic effect in the dorsocranial direction can be expected. On the other hand, it can also be achieved that the mass is first moved to the valve's end, which initially has no effect when the foot comes into contact with the floor. Then the mass is moved towards the dorsal end due to the suction generated after contact with the ground and held there until the foot starts the swing phase, during which the mass overcomes the suction or the suction ends and the mass maximally forwards is thrown.
GemƤƟ einem AusfĆ¼hrungsbeispiel ist das Reservoir mit zumindest einem Medi- um gefĆ¼llt. Das Medium sorgt dafĆ¼r, dass eine ausreichend groƟe Druckwelle er- zeugt wird, um die bewegliche Masse in Bewegung zu setzen. Dabei kann das Reservoir vollstƤndig oder auch nur zum Teil mit dem Medium befĆ¼llt sein. According to one embodiment, the reservoir is filled with at least one medium. The medium ensures that a sufficiently large pressure wave is generated to set the moving mass in motion. The reservoir can be completely or only partially filled with the medium.
Es ist denkbar, dass das Medium ein Fluid, insbesondere ein Gas wie beispiels- weise Luft oder ein Fluid mit hoher ViskositƤt, und/oder ein Festkƶrper, insbeson- dere ein schaumartiger Stoff, bspw. eine insbesondere offenporige PU Schaum- matrix ist. Durch die Verwendung bspw. eines Schaumstoffs kann zumindest ein Teil der Vorrichtung kostengĆ¼nstig hergestellt werden. AuƟerdem kann beispiels weise eine Schaummatrix gut als Pneumatikmittel dienen, welches es ermƶglicht, die Druckwelle zur Kammer hin auszusenden bzw. durch einen Sog das Reservoir wieder mit Luft zu befĆ¼llen. It is conceivable that the medium is a fluid, in particular a gas such as air or a fluid with a high viscosity, and / or a solid, in particular a foam-like substance, for example an open-pored PU foam matrix. By using a foam, for example, at least a part of the device can be produced inexpensively. In addition, for example, a foam matrix can serve well as a pneumatic means, which makes it possible to send out the pressure wave to the chamber or to refill the reservoir with air by suction.
GemƤƟ einer Variante ist die Vorrichtung am FuƟ des Benutzers zumindest ab- schnittsweise parallel zu einer LaufflƤche des FuƟes angeordnet oder anordenbar. Sowohl beim Reservoir als auch bei der Kammer hat es sich als vorteilhaft erwie- sen, wenn diese jeweils zumindest abschnittsweise parallel zur LaufflƤche des FuƟes anordenbar sind. Durch eine parallele Anordnung des Reservoirs zur Lauf- flƤche kann effektiv Druck durch den FuƟ des Benutzers auf das Reservoir ausge- Ć¼bt werden, ohne dass der Benutzer bzw. LƤufer sich in seinem Laufverhalten von der Vorrichtung gestƶrt fĆ¼hlt oder durch diese negativ beeinflusst wird. GemƤƟ einer weiteren Variante weist die Kammer eine lƤngliche, insbesondere rohrfƶrmige, Form auf. Durch die BeschrƤnkung der Bewegung der beweglichen Masse auf einen lƤnglichen Hohlraum, wird die Bewegungsrichtung der bewegli- chen Masse geometrisch vorgegeben. According to a variant, the device on the foot of the user is arranged or can be arranged at least in sections parallel to a running surface of the foot. For both the reservoir and the chamber, it has proven to be advantageous if these can be arranged at least in sections parallel to the tread of the foot. By arranging the reservoir parallel to the tread, pressure can effectively be exerted on the reservoir by the user's foot without the user or runner feeling disturbed in the running behavior of the device or being negatively influenced by it. According to a further variant, the chamber has an elongated, in particular tubular, shape. By restricting the movement of the movable mass to an elongated cavity, the direction of movement of the movable mass is predetermined geometrically.
Es ist auch denkbar, dass die Kammer eine gebogene Form aufweist. Durch die gebogene Form der Kammer soll die Bewegungsrichtung der beweglichen Masse dem natĆ¼rlich Abrollverhalten des FuƟes im Schuh angepasst werden, um die freigegebene Energie noch besser und effektiver nutzen zu kƶnnen. It is also conceivable that the chamber has a curved shape. Due to the curved shape of the chamber, the direction of movement of the movable mass should be adapted to the natural rolling behavior of the foot in the shoe in order to be able to use the released energy even better and more effectively.
Wird also die Kammer beispielsweise zusƤtzlich parallel zur LaufflƤche angeord- net, entspricht die vorgegebene Bewegungsrichtung der beweglichen Masse einer longitudinalen Richtung (also in sagittaler Ebene). Im Falle einer gebogenen Kammer entspricht die vorgegebene Bewegungsrichtung der beweglichen Masse der Bewegungsrichtung des FuƟes wƤhrend der Bewegung. Die freigegebene Energie wird somit auch in eine bestimmte Richtung gelenkt, sodass die beim Lau- fen, Gehen, Springen usw. wiedergewonnene Energie gezielt fĆ¼r eine Leistungs- Steigerung (lƤngere Schrittweiten) oder eine Leistungsminimierung (kĆ¼rzere Schrittweiten) genutzt werden kann. Letzteres kƶnnte beispielsweise im Training genutzt werden, um Ƥhnliche Effekte wie beim sogenannten Fallschirm- oder Zug- schlittentraining zu erreichen. Dieser "negative" Effekt Ƥhnelt in gewisser Hinsicht jenem eines bekannten, 3D-gedruckten Trainingsschuhs von adidas ("The Grit"), welcher den Benutzer bei jedem Schritt destabilisiert, um das Laufen auf Sand zu simulieren und somit den Widerstand beim Laufen zu erhƶhen. Der Vorteil der vor- liegenden Erfindung ist es jedoch die Mƶglichkeit der Einstellung der "Belastung", sodass diese je nach Bedarf reguliert werden kann. AuƟerdem soll die vorliegende Erfindung den Benutzer nicht aus dem Gleichgewicht bringen, um beispielsweise die FuƟgelenksmuskulatur zu stƤrken, sondern vielmehr die Laufbewegung gezielt "bremsen". In diesem Zusammenhang ist zu bemerken, dass am Kopfende der Kammer bei- spielsweise eine Feder oder Ƥhnliches vorgesehen sein kann, wenn der "negative" Effekt erzielt werden soll. Diese Feder hƤlt die bewegliche Masse so lange am Kopfende, welche sich in Bezug auf den FuƟ ventral befinden kann, fest, bis der entsprechende FuƟ sich in der Schwungphase nach vorne befindet. Dann kann durch diese Feder die Masse nach hinten an das dorsale Ende katapultiert, um die Schwungphase zu stƶren und die Schrittweite dadurch zu minimieren. If, for example, the chamber is additionally arranged parallel to the running surface, the specified direction of movement of the movable mass corresponds to a longitudinal direction (ie in the sagittal plane). In the case of a curved chamber, the predetermined direction of movement of the movable mass corresponds to the direction of movement of the foot during the movement. The released energy is thus also directed in a certain direction, so that the energy recovered when running, walking, jumping, etc. can be used specifically to increase performance (longer increments) or to minimize performance (shorter increments). The latter could be used in training, for example, to achieve effects similar to what is known as parachute or train sled training. This "negative" effect is somewhat similar to that of a well-known, 3D-printed training shoe from adidas ("The Grit"), which destabilizes the user at every step to simulate running on sand and thus increases resistance while running. The advantage of the present invention, however, is the possibility of setting the "load" so that it can be regulated as required. In addition, the present invention is not intended to unbalance the user, for example to strengthen the ankle muscles, but rather to "brake" the running movement in a targeted manner. In this connection it should be noted that a spring or the like can be provided at the head end of the chamber, for example, if the ā€œnegativeā€ effect is to be achieved. This spring holds the movable mass at the head end, which can be ventrally in relation to the foot, until the corresponding foot is in the swing phase to the front. Then this spring can catapult the mass backwards to the dorsal end to disrupt the swing phase and thereby minimize the step size.
Umgekehrt kann sich das Kopfende der Kammer auch dorsal befinden, sodass die Masse zunƤchst nach hinten geschleudert wird. Der Sog, der nach Abheben des FuƟes durch das Reservoir erzeugt wird, zieht die Masse dann wieder nach vorne (ventral) und hƤlt diese dort fest. ZusƤtzlich kann auch hier eine Feder angeordnet sein, die die Masse an dieser Stelle so lange festhƤlt, bis sich der FuƟ in der Schwungphase nach vorne befindet. Wird die Masse genau zu diesem Zeitpunkt wieder von der Feder nach dorsal geschleudert, kann dies zu einer Minimierung der Schrittweite fĆ¼hren. Conversely, the head end of the chamber can also be located dorsally, so that the mass is first thrown backwards. The suction created by the reservoir after lifting the foot then pulls the mass forward again (ventrally) and holds it there. In addition, a spring can also be arranged here, which holds the mass at this point until the foot is in the swing phase to the front. If the mass is thrown dorsally by the spring at this precise point in time, this can lead to a minimization of the step size.
Vorzugsweise ist die Kammer zumindest abschnittsweise aus einem starren Mate- rial, insbesondere aus Aluminium, geformt. Dadurch soll erreicht werden, dass bei einem Anschlag der beweglichen Masse am Ende der Kammer eine maximale Menge an Energie in Form von kinetischer Energie freigegeben wird. Zugleich sollte das Material aber auch nicht zu schwer sein, da es sich generell gezeigt hat, dass Schuhe als angenehmer, effektiver und besser vom LƤufer empfunden wer- den, je weniger Gewicht sie aufweisen. Bekannterweise reduziert nƤmlich eine Gewichtsersparnis von 100g den Sauerstoffbedarf eines durchschnittlichen LƤu- fers um 1 %. The chamber is preferably formed at least in sections from a rigid material, in particular from aluminum. This is intended to ensure that a maximum amount of energy in the form of kinetic energy is released when the movable mass strikes the end of the chamber. At the same time, the material should not be too heavy, since it has generally been shown that shoes are perceived as more comfortable, effective and better by the runner, the less weight they have. As is known, a weight saving of 100 g reduces the oxygen requirement of an average runner by 1%.
GemƤƟ einer AusfĆ¼hrungsform stimmt die LƤngserstreckung der Kammer zumin- dest im Wesentlichen mit einer Laufrichtung parallel zu einer LƤngsrichtung der LaufflƤche Ć¼berein. Durch eine solche Anordnung der Kammer kann die wieder- gewonnene Energie gezielt fĆ¼r eine Leistungssteigerung bzw. fĆ¼r eine Leistungs- minimierung ausgenĆ¼tzt werden. According to one embodiment, the longitudinal extent of the chamber is at least essentially correct with a running direction parallel to a longitudinal direction of the Tread. By arranging the chamber in this way, the recovered energy can be used in a targeted manner to increase performance or to minimize performance.
In diesem Zusammenhang ist anzumerken, dass die LƤngserstreckung der Kam- mer auch schrƤg zu der Laufrichtung bzw. zur LaufflƤche des FuƟes gestellt sein kann. Dies ermƶglicht z.B. eine Verbesserung eines Schusses beim Treten eines Balles, wie es beispielsweise beim FuƟball vorkommt. In this context it should be noted that the longitudinal extent of the chamber can also be set at an angle to the running direction or to the running surface of the foot. This enables e.g. an improvement in a shot when kicking a ball, such as occurs in football.
GemƤƟ einer alternativen AusfĆ¼hrungsform stimmt die LƤngserstreckung der Kammer zumindest im Wesentlichen mit einer Laufrichtung quer zu der LƤngsrich- tung der LaufflƤche Ć¼berein. Somit soll die wiedergewonnene Energie bei Sportar- ten genutzt werden kƶnnen, bei denen der FuƟ des Benutzers im Wesentlichen senkrecht zur Laufrichtung steht, wie es zum Beispiel in der Beschleunigungspha- se beim Eishockey oder beim Eisschnelllauf der Fall ist. According to an alternative embodiment, the longitudinal extent of the chamber corresponds at least substantially to a running direction transverse to the longitudinal direction of the running surface. Thus, the recovered energy should be able to be used in sports in which the user's foot is essentially perpendicular to the running direction, as is the case, for example, in the acceleration phase in ice hockey or in speed skating.
Bevorzugt ist die bewegliche Masse in einer LƤngsrichtung oder Querrichtung des Hohlraums der Kammer hin und her bewegbar. Je nachdem welche Form die Kammer bzw. die bewegliche Masse aufweisen, kann sich die bewegliche Masse in LƤngs- oder in Querrichtung der Kammer bewegen. The movable mass can preferably be moved back and forth in a longitudinal or transverse direction of the cavity of the chamber. Depending on the shape of the chamber or the movable mass, the movable mass can move in the longitudinal or transverse direction of the chamber.
Vorzugsweise ist die bewegliche Masse eine oder mehrere Kugeln oder weist eine andere geometrische Form auf. Damit bewegt sich beispielsweise die Kugel bzw. die Kugeln zumindest im Wesentlichen in LƤngsrichtung oder Querrichtung der Kammer oder schrƤg in der Kammer vor und zurĆ¼ck. The movable mass is preferably one or more balls or has a different geometric shape. Thus, for example, the ball or balls move back and forth at least substantially in the longitudinal or transverse direction of the chamber or obliquely in the chamber.
Es ist denkbar, dass der Durchmesser der Kugel bzw. der mehreren Kugeln je- weils im Bereich von 0,2 bis 20mm liegt, vorzugsweise im Bereich von 1 bis Bevorzugt ist die bewegliche Masse aus einem starren Material, insbesondere aus Stahl, geformt. Es wƤre aber auch mƶglich, dass die Kugel aus anderen Materia- lien wie beispielsweise Quecksilber geformt ist. Idealerweise fĆ¼hrt die bewegliche Masse somit einen annƤhernd ideal elastischen StoƟ am jeweiligen Ende der Vor- richtung aus, damit maximal viel Energie in Form von kinetischer Energie freige- setzt wird und so wenig wie mƶglich Energie in Form von Deformationen der Mate- rialen usw. verloren geht. It is conceivable that the diameter of the ball or the plurality of balls is in each case in the range from 0.2 to 20 mm, preferably in the range from 1 to The movable mass is preferably formed from a rigid material, in particular from steel. However, it would also be possible for the ball to be formed from other materials, such as mercury. Ideally, the moveable mass therefore executes an approximately ideal elastic impact at the respective end of the device, so that a maximum of energy is released in the form of kinetic energy and as little energy as possible is lost in the form of deformations of the materials, etc. goes.
GemƤƟ einer AusfĆ¼hrungsform weist die Kammer zumindest ein Loch auf. Eine Druckwelle ist in der Praxis auch immer mit einer Dichtewelle gleichzusetzen, da sich die Druckwelle in Luft (also einem Gas) ausbreitet. Damit die Dichtewelle, die sich aufgrund der Beaufschlagung des Reservoirs mit Druck durch die Vorrichtung bewegt, am Ende der Vorrichtung entweichen kann, ist zumindest ein Loch vorge- sehen, durch das das in Bewegung gesetzte Gas entweichen kann. Ebenso ist das Loch auch notwendig, um im Anschluss wieder Luft anzusaugen, damit die Vorrichtung wieder ihren Ausgangszustand einnehmen kann. According to one embodiment, the chamber has at least one hole. In practice, a pressure wave is always to be equated with a density wave, since the pressure wave spreads in air (i.e. a gas). So that the density wave, which moves through the device due to the pressurization of the reservoir, can escape at the end of the device, at least one hole is provided through which the gas set in motion can escape. The hole is also necessary in order to subsequently suck in air again so that the device can return to its initial state.
GemƤƟ einer weiteren AusfĆ¼hrungsform ist zumindest eine AuƟenwand des Re- servoirs aus einem elastischen Material, insbesondere aus Silikon, geformt. Das elastische Material kann sich durch die Beaufschlagung mit Druck verformen und damit eine Druckwelle im Inneren des Reservoirs erzeugen. Im Anschluss kann sich das Material allerdings ohne Fremdeinwirkung wieder in seinen Ausgangszu- stand zurĆ¼ckformen, damit dabei eine weitere, sich in eine entgegengesetzte Rich- tung bewegende Welle vom Reservoir angesaugt werden kann. According to a further embodiment, at least one outer wall of the reservoir is formed from an elastic material, in particular from silicone. When subjected to pressure, the elastic material can deform and thus generate a pressure wave inside the reservoir. Subsequently, however, the material can return to its original state without any external influence, so that a further wave moving in an opposite direction can be sucked in by the reservoir.
Vorzugsweise umfasst das Reservoir eine Silikonkammer. Eine aus Silikon gefer- tigte Kammer kann kostengĆ¼nstig hergestellt werden und im Zusammenhang mit deren FĆ¼llung, bspw. einer PU Schaummatrix sowohl die gewĆ¼nschte Abfederung in der Sohle als auch die gewĆ¼nschte Erzeugung der Druckwelle positiv beeinflus- sen. Vorzugsweise ist der Ɯbertragungsbereich aus einem flexiblen Material geformt. Somit kann die Vorrichtung individuell an den jeweiligen Benutzer oder den jewei- ligen Schuh angepasst werden. The reservoir preferably comprises a silicone chamber. A chamber made of silicone can be manufactured inexpensively and, in connection with its filling, for example a PU foam matrix, can positively influence both the desired cushioning in the sole and the desired generation of the pressure wave. The transmission area is preferably formed from a flexible material. The device can thus be individually adapted to the respective user or the respective shoe.
GemƤƟ einer AusfĆ¼hrungsform weist der Ɯbertragungsbereich eine lƤngliche Form auf. Eine VerlƤngerung bzw. eine lƤngliche Form des Ɯbertragungsbereichs ermƶglicht es, dass sich das Reservoir und die Kammer beispielsweise an zwei verschiedenen Orten am Schuh befinden kƶnnen. So kann beispielsweise sogar das Reservoir in der Sohle angeordnet werden, wƤhrend die Kammer in einem Oberteil des Schuhs angeordnet sein kann. AuƟerdem kann somit frei gewƤhlt werden in welcher Orientierung zur Laufrichtung sich die zuerst bewegliche Masse bewegen soll. According to one embodiment, the transmission area has an elongated shape. An extension or an elongated shape of the transmission area enables the reservoir and the chamber to be located, for example, at two different locations on the shoe. For example, the reservoir can even be arranged in the sole, while the chamber can be arranged in an upper part of the shoe. In addition, you can freely choose in which orientation to the direction of travel the first moving mass should move.
GemƤƟ einer weiteren AusfĆ¼hrungsform ist der Ɯbertragungsbereich ein Schlauch bzw. ein SchlƤuchen. Ein Schlauch hat den Vorteil, dass dieser flexibel einsetzbar ist, da er beispielsweise gebogen oder in Kurven gelegt werden kann, ohne dabei zu brechen. Dadurch lƤsst sich die Vorrichtung flexibel je nach Anwendung am Schuh platzieren. According to a further embodiment, the transmission area is a hose or a hose. The advantage of a hose is that it can be used flexibly, for example because it can be bent or placed in curves without breaking. This allows the device to be placed flexibly on the shoe depending on the application.
GemƤƟ einer noch weiteren AusfĆ¼hrungsform umfasst der Ɯbertragungsbereich zwei oder mehrere SchlƤuche. Die mehreren SchlƤuche kƶnnen alle von einem einzigen Reservoir ausgehen und in eine gemeinsame Kammer mĆ¼nden. Es wƤre aber auch denkbar, dass an jedem Schlauch eine Kammer angeordnet ist und die Vorrichtung somit mehrere Kammern aufweist. According to yet another embodiment, the transmission area comprises two or more hoses. The multiple hoses can all start from a single reservoir and open into a common chamber. However, it would also be conceivable that a chamber is arranged on each hose and the device thus has a plurality of chambers.
Eine weitere AusfĆ¼hrungsform sieht es auch vor, dass zwei oder mehrere Reser- voirs vorgesehen sind. Diese kƶnnen jeweils einzelne Ɯbertragungsbereiche auf- weisen, die in eine gemeinsame Kammer oder in jeweils einzelne Kammern mĆ¼n- den kƶnnen. Demnach kann es bei dieser AusfĆ¼rungsform auch mƶglich sein, dass auf jedes Reservoir zunƤchst jeweils ein separater Schlauch folgt, welche im Anschluss in einen einzelnen Schlauch Ć¼bergehen, der in einer Kammer mĆ¼ndet. Another embodiment also provides that two or more reservoirs are provided. These can each have individual transmission areas, which can open into a common chamber or into individual chambers. Accordingly, it can also be possible with this embodiment that each reservoir is followed by a separate hose, which then merges into a single hose that opens into a chamber.
ErfindungsgemƤƟ ist auch ein Schuh mit zumindest einem Oberteil aus zumindest einem Obermaterial und einer Sohle vorgesehen, wobei im Bereich der Sohle zu- mindest eine erfindungsgemƤƟe Vorrichtung angeordnet oder anordenbar ist. Zu- mindest das Reservoir sollte derart im Bereich der Sohle angeordnet sein, dass der TrƤger der Schuhe, wƤhrend der Bewegung mit seinen FĆ¼ĆŸen Druck auf das Reservoir ausĆ¼ben kann. According to the invention, a shoe with at least one upper part made of at least one upper material and a sole is also provided, at least one device according to the invention being arranged or arranged in the area of the sole. At least the reservoir should be arranged in the area of the sole such that the wearer of the shoes can exert pressure on the reservoir with his feet during the movement.
Vorzugsweise ist das Reservoir an einem VorderfuƟbereich, einem MittelfuƟbe- reich und/oder einem Fersenbereich der Sohle angeordnet und/oder anordenbar. Je nachdem welchem Lauftyp ein LƤufer entspricht, kann damit der passende Schuh gewƤhlt werden, der das Reservoir an der entsprechenden Stelle aufweist. Denkbar wƤre es auch, dass der Schuh lediglich das GrundgerĆ¼st darstellt und der LƤufer selbst die Vorrichtung bzw. die mehreren Vorrichtungen seinen BedĆ¼rfnis- sen entsprechend am Schuh anordnen kann. Im Training kann beispielsweise die Anordnung derart gewƤhlt werden, dass die Abfolge der Druckwellen in die ver- schiedenen Richtungen derart gewƤhlt wird, dass die Schrittweiten minimiert wer- den. Umgekehrt kann im Wettkampf die Anordnung derart gewƤhlt sein, dass die Vorrichtung die Schrittweiten optimiert bzw. verlƤngert. The reservoir is preferably arranged and / or can be arranged on a forefoot area, a midfoot area and / or a heel area of the sole. Depending on the type of run a runner corresponds to, the right shoe can be selected that has the reservoir at the corresponding point. It would also be conceivable that the shoe merely represents the basic structure and that the runner himself can arrange the device or the multiple devices on the shoe according to his needs. In training, for example, the arrangement can be selected such that the sequence of the pressure waves in the different directions is selected such that the step sizes are minimized. Conversely, in the competition the arrangement can be chosen such that the device optimizes or extends the step sizes.
GemƤƟ einem AusfĆ¼hrungsbeispiel ist das Reservoir ein Bestandteil der Sohle. Schuhsohlen von Sportschuhen bestehen oftmals ohnehin aus mehreren ver- schiedenen Lagen, die zum Teil auch aus verschiedenen Materialien gefertigt werden. Somit wƤre es aus denkbar, dass das Reservoir direkt als Bestandteil der Sohle - beispielsweise als eine Zwischensohle - gefertigt wird, um die Herstellung zu vereinfachen. GemƤƟ einer Variante erstreckt sich das Reservoir Ć¼ber den gesamten Bereich der Sohle. Mit Hilfe dieser AusfĆ¼hrungsform kann ein Schuh geschaffen werden, der einheitlich fĆ¼r alle LƤufertypen eingesetzt werden kann, egal ob es sich im Vorder-, Mittel- oder FersenfuƟlƤufer handelt. Erstreckt sich das Reservoir Ć¼ber den gesamten Bereich der Sohle, kann mit demselben Schuh jeder Laufstiltyp be- dient werden. Dies erscheint auch in der Hinsicht besonders vorteilhaft, als dass sich bei vielen LƤufern der Laufstil je nach Geschwindigkeit verƤndert. According to one embodiment, the reservoir is part of the sole. Shoe soles of sports shoes often consist of several different layers, some of which are made from different materials. It would therefore be conceivable for the reservoir to be manufactured directly as part of the sole, for example as a midsole, in order to simplify production. According to a variant, the reservoir extends over the entire area of the sole. With the help of this embodiment, a shoe can be created which can be used uniformly for all types of runners, regardless of whether it is in the front, middle or heel foot runners. If the reservoir extends over the entire area of the sole, any type of running style can be served with the same shoe. This also appears to be particularly advantageous in that in many runners the running style changes depending on the speed.
In einer AusfĆ¼hrungsform stimmt die LƤngserstreckung der Kammer parallel mit der LƤngserstreckung der Sohle Ć¼berein. Somit kann die Bewegung der bewegli- chen Masse zumindest im Wesentlichen auf die sagittale Ebene des Benutzers reduziert werden. In one embodiment, the longitudinal extent of the chamber is parallel to the longitudinal extent of the sole. The movement of the movable mass can thus be reduced at least essentially to the sagittal plane of the user.
In einer weiteren AusfĆ¼hrungsform ist die LƤngserstreckung der Kammer zumin- dest teilweise quer zur LƤngserstreckung der Sohle. Somit kƶnnen einerseits Sportarten bedient werden, bei denen der FuƟ des Benutzers im Wesentlichen quer bzw. auch schrƤg zur Laufrichtung steht, wie es in der Beschleunigungspha- se beim EislƤufen bei Eishockeyspielern oder EisschnelllƤufern der Fall ist. Ande- rerseits ist aber auch denkbar, dass die bewegliche Masse eine lƤngliche Form aufweist, die sich Ć¼ber die Breite der Sohle erstreckt, und sich in longitudinaler Richtung nach vorne und nach hinten bewegt. In a further embodiment, the longitudinal extent of the chamber is at least partially transverse to the longitudinal extent of the sole. Thus, on the one hand, sports can be operated in which the user's foot is essentially transverse or also at an angle to the running direction, as is the case in the acceleration phase when ice skating for ice hockey players or speed skaters. On the other hand, however, it is also conceivable that the movable mass has an elongated shape that extends across the width of the sole and moves forwards and backwards in the longitudinal direction.
Vorteilhafterweise ist die Vorrichtung in die Sohle eingebettet. Aus KomfortgrĆ¼n- den sowie aus optischen GrĆ¼nden kann es vorteilhaft sein, wenn die gesamte Vor- richtung in der Sohle der Schuhe eingebettet ist. Somit Ƥhnelt der Schuhe von au- Ɵen einem herkƶmmlichen Schuh. Vorzugsweise ist die Vorrichtung derart in der Sohle angeordnet, dass der TrƤger keinen Unterschied im Tragekomfort zu einem herkƶmmlichen Schuh merkt. GemƤƟ einer AusfĆ¼hrungsform ist eine Ausrichtung, insbesondere eine Neigung, der Kammer einstellbar oder vorbestimmbar. Je nach Laufverhalten, Trainingsein- heit oder auch Geschmack soll der TrƤger des Schuhs so damit flexibel eine Nei- gung der Kammer passend einstellen kƶnnen, um den gewĆ¼nschten Effekt auf das Laufverhalten des Benutzers besser abzustimmen. The device is advantageously embedded in the sole. For reasons of comfort and for optical reasons, it can be advantageous if the entire device is embedded in the sole of the shoes. The outside of the shoes thus resembles a conventional shoe. The device is preferably arranged in the sole such that the wearer does not notice any difference in comfort compared to a conventional shoe. According to one embodiment, an orientation, in particular an inclination, of the chamber is adjustable or predeterminable. Depending on the running behavior, training unit or taste, the wearer of the shoe should be able to flexibly adjust the inclination of the chamber to better match the desired effect on the running behavior of the user.
GemƤƟ einer weiteren AusfĆ¼hrungsform ist die Ausrichtung durch eine Verstellvor- richtung, insbesondere durch eine Stellschraube, einstellbar. Bspw. ist die Ver- stellvorrichtung derart in dem Schuh angeordnet, dass ein Benutzer vor dem Lau- fen den Schuh auf die gewĆ¼nschte Neigung einstellen kann, sodass dieser fĆ¼r die gewĆ¼nschte Anwendung voreingestellt wird. Bspw. ist wird bei einem Langstre- ckenlƤufer eine andere Neigung gewƤhlt als bei einem Sprint oder beim Gehen. According to a further embodiment, the alignment can be adjusted by an adjusting device, in particular by an adjusting screw. For example. the adjustment device is arranged in the shoe in such a way that a user can adjust the shoe to the desired incline before running, so that it is preset for the desired application. For example. a different inclination is chosen for a long distance runner than for a sprint or when walking.
Die Verstellvorrichtung kann auch derart ausgestaltet sein, dass sie als Ein- bzw. Ausschaltvorrichtung dient. So kann ein Benutzer je nach Anwendung flexibel am Schuh einstellen, ob die Vorrichtung aktiv sein soll oder nicht. Beispielsweise kann der Benutzer beim einfachen Gehen die Vorrichtung inaktiv lassen, um beispiels weise ein eventuell vorhandenes unerwĆ¼nschtes KlickgerƤusch der Masse zu un- terdrĆ¼cken, welches beim StoƟ der Masse gegen die KammerwƤnde entsteht. Ei- ne derartige Ein- und Ausschaltvorrichtung kann beispielsweise derart ausgebildet sein, dass sie die Masse bei ausgeschaltetem Zustand so festhƤlt, dass sich diese nicht bewegen kann, die Luftzirkulation innerhalb der Kammer jedoch nicht beein- flusst wird, um ein Komprimieren des Reservoirs dennoch zu ermƶglichen. The adjustment device can also be designed such that it serves as an on or off device. Depending on the application, a user can flexibly adjust the shoe whether the device should be active or not. For example, the user can leave the device inactive while simply walking, in order to suppress, for example, any unwanted clicking sound of the mass that occurs when the mass hits the chamber walls. Such a switch-on and switch-off device can, for example, be designed in such a way that it holds the mass in the switched-off state in such a way that it cannot move, but the air circulation within the chamber is not influenced in order to nevertheless compress the reservoir enable.
Die Erfindung wird nachfolgend rein beispielhaft unter Bezugnahmen auf die Zeichnungen nƤher erlƤutert. In diesen zeigen: The invention is explained below purely by way of example with reference to the drawings. In these show:
Fig. 1 eine schematische Draufsicht einer erfindungsgemƤƟen Vorrichtung; Figure 1 is a schematic plan view of a device according to the invention.
Fig. 2 einen schematischen Schnitt der erfindungsgemƤƟen Vorrichtung; und Fig. 3 einen schematischer Schnitt eines beispielhaften Schuhs. 2 shows a schematic section of the device according to the invention; and Fig. 3 shows a schematic section of an exemplary shoe.
Die in Figur 1 in einer Draufsicht schematisch dargestellte Vorrichtung 10 zur Un- terstĆ¼tzung der Fortbewegung eines Benutzers weist ein Reservoir 12, einen Ɯbertragungsbereich 14 in Form eines Schlauchs und eine Kammer 16 auf. The device 10 schematically shown in a plan view in FIG. 1 to support the movement of a user has a reservoir 12, a transmission area 14 in the form of a hose and a chamber 16.
Die Kammer 16 ist in der gezeigten AusfĆ¼hrungsform ein lƤngliches Rohr, das an seinem einen Ende 38, das dem Ɯbertragungsbereich 14 gegenĆ¼ber liegt, ein Loch 26 aufweist (siehe Fig. 2). Es sind aber auch andere Formen und Ausgestal- tungen fĆ¼r die Kammer 16 denkbar. Ebenso kann das Loch 26 auch an einer Seite bzw. Seitenwand 40 der Kammer 16 anstatt am Kopfende 38 der Kammer 16 an- geordnet sein. Ebenso ist es mƶglich, dass mehrere Lƶcher 26 an der Kammer 16 vorgesehen sind. In the embodiment shown, the chamber 16 is an elongated tube which has a hole 26 at one end 38, which lies opposite the transmission region 14 (see FIG. 2). However, other shapes and configurations for the chamber 16 are also conceivable. Likewise, the hole 26 can also be arranged on one side or side wall 40 of the chamber 16 instead of at the head end 38 of the chamber 16. It is also possible that several holes 26 are provided on the chamber 16.
Die schlauchfƶrmige Ausgestaltung des Ɯbertragungsbereichs 14 soll es ermƶgli- chen, dass das Reservoir 12 prinzipiell an einer beliebigen Stelle an der Sohle 34 eines Schuhs 30 (siehe Fig. 3) eingesetzt werden kann, unabhƤngig davon an welcher Stelle der Sohle 34 oder des Oberteils 32 die Kammer 16 platziert werden soll. The tubular design of the transmission area 14 is intended to make it possible, in principle, for the reservoir 12 to be used anywhere on the sole 34 of a shoe 30 (see FIG. 3), irrespective of the position of the sole 34 or the upper 32 the chamber 16 is to be placed.
Der Ɯbertragungsbereich 14 dient dazu, dass eine im Reservoir 12 erzeugte Druckwelle in die Kammer 16 bzw. den Hohlraum der Kammer 16 transportiert werden kann. Der Ɯbertragungsbereich 14 stellt also das Verbindungselement zwischen Reservoir 12 und Kammer 16 dar. The transmission area 14 serves to allow a pressure wave generated in the reservoir 12 to be transported into the chamber 16 or the cavity of the chamber 16. The transmission area 14 thus represents the connecting element between the reservoir 12 and the chamber 16.
Das Reservoir 12 ist dabei derart ausgebildet, dass es mit Druck beaufschlagt werden kann, wenn beispielsweise der LƤufer bei einem Schritt mit seinem FuƟ auf das Reservoir 12 drĆ¼ckt. Dabei verformt sich das GehƤuse des Reservoirs 12 und das sich darin befindliche Medium 22 und erzeugt somit eine Druckwelle im Inneren des Reservoirs 12, welche sich Ć¼ber den Ɯbertragungsbereich 14 in Rich- tung der Kammer 16 ausbreiten kann, um dort die bewegliche Masse in Bewe- gung zu versetzen. The reservoir 12 is designed such that pressure can be applied when, for example, the runner presses the foot 12 on the reservoir 12 during one step. The housing of the reservoir 12 and the medium 22 located therein are deformed and thus generate a pressure wave in the Inside of the reservoir 12, which can spread out over the transmission area 14 in the direction of the chamber 16 in order to set the movable mass in motion there.
Damit ist es beispielsweise denkbar, dass die Kammer 16 derart angeordnet wird, dass die sich im Hohlraum der Kammer 16 befindliche bewegliche Masse 20 von einem Fersenbereich FB in Richtung eines VorderfuƟbereichs VB bewegt, wenn das Reservoir 12 mit Druck beaufschlagt wird. AnschlieƟend wird die bewegliche Masse 20 zurĆ¼ck in Richtung Reservoir gezogen, wenn die Beaufschlagung been- det wird, d.h. wenn sich der FuƟ in jener Phase des Bewegungsablaufes befindet, wo er den Kƶrper vom Boden nach schrƤg vorne abdrĆ¼ckt. Der FuƟ befindet sich zu diesem Zeitpunkt hinter dem Kƶrperschwerpunkt. Die Masse 20 wird zu diesem Zeitpunkt von dem durch das Reservoir erzeugten Sog am hinteren Ende der Kammer 16, also am Fersenbereich FB des FuƟes gehalten. Bei der anschlieƟen- den Schwung beweg ung des FuƟes nach vorne wird die bewegliche Masse 20 er- neut nach vorne in Richtung des Kopfendes 38 der Kammer 16 bewegt, bis sie an das Kopfende 38 stĆ¶ĆŸt. Dies kann dazu beitragen, dass die Schrittweite eines LƤufers, der Schuhe 30 mit den entsprechenden Vorrichtungen 10 trƤgt, aufgrund der wiedergewonnenen Energie verlƤngert wird, was sowohl zu einem dynami- scheren als auch zu einem schnelleren Laufen fĆ¼hren kann. It is thus conceivable, for example, that the chamber 16 is arranged such that the movable mass 20 located in the cavity of the chamber 16 moves from a heel area FB in the direction of a forefoot area VB when the reservoir 12 is pressurized. The moveable mass 20 is then pulled back towards the reservoir when the loading is ended, i.e. when the foot is in that phase of the movement sequence, where it pushes the body from the floor forward. At this point the foot is behind the center of gravity. The mass 20 is held at this time by the suction generated by the reservoir at the rear end of the chamber 16, that is to say at the heel area FB of the foot. During the subsequent swing movement of the foot forward, the movable mass 20 is again moved forward in the direction of the head end 38 of the chamber 16 until it abuts the head end 38. This can contribute to the step size of a runner wearing shoes 30 with the corresponding devices 10 being lengthened due to the recovered energy, which can lead to both more dynamic and faster running.
Alternativ dazu, ist es auch mƶglich, die Kammer 16 derart anzuordnen, dass sich die bewegliche Masse 20 mit jedem Auftreten von dem VorderfuƟbereich VB in Richtung des Fersenbereichs FB bewegt. Das Kopfende der Kammer 16 befindet sich hierbei also im Fersenbereich FB des FuƟes. Um insgesamt einen gegenteili- gen Effekt zu erzielen und damit bewusst ein Widerstand - und somit eine kĆ¼rzere Schrittweite - fĆ¼r den LƤufer zu erzeugen, ist bei dieser AusfĆ¼hrungsform an je- nem Ende der Kammer 16, welches an den Ɯbertragungsbereich angrenzt, eine (nicht dargestellte) Feder oder Ƥhnliches vorgesehen, welche die Masse 20, die nach Beendigung der Beaufschalgung des Reservoirs 12 wieder zurĆ¼ck - in die- sem Fall in Richtung VorderfuƟbereich VB - gesogen wird, so lange festzuhalten, bis sich der FuƟ in der Schwungphase befindet. In dieser anschlieƟenden Alternatively, it is also possible to arrange the chamber 16 in such a way that the movable mass 20 moves from the forefoot region VB in the direction of the heel region FB with each occurrence. The head end of the chamber 16 is thus in the heel area FB of the foot. In order to achieve an overall opposite effect and thus deliberately create a resistance - and thus a shorter step size - for the rotor, in this embodiment there is one (not shown) at each end of the chamber 16 which adjoins the transmission area ) Spring or the like is provided which the mass 20, which after the application of the reservoir 12 has ended, back again - into this - case in the direction of the forefoot area VB - is to be held until the foot is in the swing phase. In this subsequent
Schwungphase nach vorne kann die Feder dann die Masse 20 in Richtung Kopf- ende der Kammer 16 - also in Richtung Fersenbereich FB - katapultieren, sodass der Schritt des Benutzers gezielt verkĆ¼rzt werden kann. Dieser Effekt kann bei spielsweise gezielt im Training als spezieller Trainingsreiz eingesetzt werden. Swing phase forward, the spring can then catapult the mass 20 towards the head end of the chamber 16 - ie towards the heel area FB - so that the user's step can be shortened in a targeted manner. This effect can be used specifically in training as a special training stimulus.
Der Fig. 2 ist des Weiteren zu entnehmen, dass das Reservoir 12 mit einem Medi- um 22 gefĆ¼llt ist. Das Medium 22 kann sowohl ein Feststoff als auch ein Gas und/oder eine viskose FlĆ¼ssigkeit sein. Im Falle einer FlĆ¼ssigkeit muss diese aller dings eine derart hohe ViskositƤt aufweisen, dass sie nicht in den Ɯbertragungs- bereich 14 lƤuft, wenn Druck auf das Reservoir 12 ausgeĆ¼bt wird. FIG. 2 also shows that the reservoir 12 is filled with a medium 22. The medium 22 can be a solid as well as a gas and / or a viscous liquid. In the case of a liquid, however, it must have such a high viscosity that it does not run into the transmission area 14 when pressure is exerted on the reservoir 12.
Alternativ hierzu kann eine Membran (nicht gezeigt) vorgesehen sein, die es er- mƶglicht eine im Reservoir 12 erzeugte Druckwelle an den Ɯbertragungsbereich 14 derart weiterzuleiten, dass die Druckwelle die gewĆ¼nschte Beschleunigung der beweglichen Masse 20 in der Kammer 16 erzeugt. Alternatively, a membrane (not shown) can be provided, which enables a pressure wave generated in the reservoir 12 to be forwarded to the transmission area 14 in such a way that the pressure wave generates the desired acceleration of the movable mass 20 in the chamber 16.
Es wƤre diesbezĆ¼glich aber auch denkbar, dass sich das die FlĆ¼ssigkeit 22 zu- sƤtzlich in einem Kissen befindet, welches innerhalb des Reservoirs 12 angeord- net ist, damit sie nicht auslaufen kann. In this regard, however, it would also be conceivable that the liquid 22 is additionally located in a cushion which is arranged inside the reservoir 12 so that it cannot run out.
Um das Medium 22 innerhalb des Reservoirs 12 effektiv mit Druck beaufschlagen zu kƶnnen, ist es vorteilhaft, wenn zumindest eine AuƟenwand 28 des Reservoirs 12 aus Silikon geformt ist. Ebenso ist es auch denkbar, dass das gesamte GehƤu- se des Reservoirs 12 aus Silikon geformt ist. Dadurch kann sich das Reservoir 12 bei der Beaufschlagung mit Druck verformen und eine Druckwelle in Richtung des Ɯbertragungsbereichs 14 aussenden und damit die Kugel 20 in Bewegung verset- zen. AnschlieƟend ziehen sich die AuƟenwand 28 bzw. die AuƟenwƤnde 28 wie- der in ihre Ausgangsposition zurĆ¼ck, damit die Kugel 20 wieder in Richtung des Reservoirs 12 gezogen wird. In order to be able to effectively apply pressure to the medium 22 within the reservoir 12, it is advantageous if at least one outer wall 28 of the reservoir 12 is formed from silicone. It is also conceivable that the entire housing of the reservoir 12 is molded from silicone. As a result, the reservoir 12 can deform when pressurized and emit a pressure wave in the direction of the transmission region 14 and thus set the ball 20 in motion. Then the outer wall 28 or the outer walls 28 pull again. which returns to its starting position so that the ball 20 is pulled again in the direction of the reservoir 12.
Fig. 3 zeigt einen Schnitt eines schematischen erfindungsgemƤƟen Schuhs 30. In der gezeigten AusfĆ¼hrungsform ist die gesamte Vorrichtung 10 eine Zwischensoh- le 34A des Schuhs 30 eingebettet, die auch fĆ¼r die DƤmpfung des Schuhs 30 ver- antwortlich ist. Eine weitere AuƟensohle 34B ist unterhalb der Zwischensohle 34A angeordnet und dient dazu, dass der Schuh 30 die nƶtige Griffigkeit beim Laufen aufweist. 3 shows a section of a schematic shoe 30 according to the invention. In the embodiment shown, the entire device 10 is embedded in an intermediate sole 34A of the shoe 30, which is also responsible for the damping of the shoe 30. A further outsole 34B is arranged below the midsole 34A and serves to ensure that the shoe 30 has the necessary grip when running.
Das Reservoir 12 ist in dieser AusfĆ¼hrungsform im MittelfuƟbereich MB des Schuhs 30 angeordnet. Der Ɯbergansbereich 14 und die Kammer 16 sind derart eingebettet, dass sich die Kugel 20, die sich innerhalb der Kammer 16 befindet, bei jeder Kompression des Reservoirs 12 vom Fersenbereich FB aus in Richtung des MittelfuƟbereichs MB bewegt und somit zur nƤchsten Phase Ć¼bergeleitet ist. Ebenso wƤre es auch aber denkbar, dass die Kammer 16 in einer anderen Orien- tierung in der Zwischensohle 34A eingebettet ist. In this embodiment, the reservoir 12 is arranged in the midfoot area MB of the shoe 30. The transition area 14 and the chamber 16 are embedded in such a way that the ball 20, which is located within the chamber 16, moves from the heel area FB towards the midfoot area MB each time the reservoir 12 is compressed and is thus transferred to the next phase. However, it would also be conceivable for the chamber 16 to be embedded in the midsole 34A in a different orientation.
Unmittelbar Ć¼ber der Kammer 16 ist im gezeigten AusfĆ¼hrungsbeispiel auch eine Verstellvorrichtung 36 angeordnet, mit deren Hilfe eine Neigung der Kammer 16 individuell vom TrƤger der Schuhe 30 einstellbar ist. Eine derartige Verstellvorrich- tung 36 kann prinzipiell auch an anderen Positionen am Schuh 30 angeordnet werden. Bevorzugt handelt es sich hierbei um eine Verstellschraube 36, die Ć¼ber eine einfache (nicht dargestellte) Mechanik die Neigung der Kammer 16 verstellen kann. So kann die Kammer 16 Ć¼ber die Verstellvorrichtung 36 beispielsweise um eine horizontale Achse H verkippt werden, sodass das Kopfende 38 der Kammer 16 beispielsweise nƤher zur AuƟensohle 34B hin verstellt wird. Es wƤre allerdings auch denkbar, dass die Kammer 16 um eine nicht dargestellte vertikale Achse verkippt wird, um eventuelle FuƟfehlstellungen des TrƤgers zu kompensieren. Bei der Verwendung der erfindungsgemƤƟen Vorrichtung 10 in einem Schuh 30 wird bei jedem Schritt in der Bodenkontaktphase des entsprechenden FuƟes Druck Ć¼ber den FuƟ des LƤufers auf das Reservoir 12 ausgeĆ¼bt. Dadurch wird eine Druckwelle erzeugt, welche sich Ć¼ber den Ɯbertragungsbereich 14 in Rich- tung der Kammer 16 bewegt. An dem dem Ɯbertragungsbereich 14 zugewandten Ende 42 der Kammer 16 trifft die Druckwelle schlieƟlich auf die bewegliche Masse 20 und setzt diese damit in Bewegung. In the exemplary embodiment shown, an adjusting device 36 is also arranged directly above the chamber 16, with the aid of which an inclination of the chamber 16 can be individually adjusted by the wearer of the shoes 30. Such an adjustment device 36 can in principle also be arranged at other positions on the shoe 30. This is preferably an adjusting screw 36 which can adjust the inclination of the chamber 16 using a simple mechanism (not shown). For example, the chamber 16 can be tilted about a horizontal axis H via the adjusting device 36, so that the head end 38 of the chamber 16 is moved closer to the outsole 34B, for example. However, it would also be conceivable for the chamber 16 to be tilted about a vertical axis (not shown) in order to compensate for possible misalignments of the wearer. When the device 10 according to the invention is used in a shoe 30, pressure is exerted on the reservoir 12 via the foot of the runner at each step in the ground contact phase of the corresponding foot. As a result, a pressure wave is generated which moves over the transmission area 14 in the direction of the chamber 16. At the end 42 of the chamber 16 facing the transmission area 14, the pressure wave finally hits the movable mass 20 and sets it in motion.
Sobald der LƤufer den FuƟ vom Boden abhebt, zieht sich das Reservoir 12 in sei- ne Ausgangsform zurĆ¼ck und saugt dabei durch das Loch 26 am Kopfende 38 der Kammer 16 Luft an. Dadurch wird auch die bewegliche Masse 20 wieder zurĆ¼ck in Richtung Ende 42 gefĆ¼hrt bis sie an das Ende 42 der Kammer 16 stĆ¶ĆŸt und dort durch den erzeugten Sog zunƤchst gehalten. In der anschlieƟenden Schwung- phase des FuƟes wird die bewegliche Masse 20 letztendlich durch die VorwƤrts- bewegung des FuƟes vom dorsalen Ende 42 der Kammer 16 zum Kopfende 38 der Kammer 16 beschleunigt bis sie an deren Ende stĆ¶ĆŸt. Die Bewegung des Fu- Ɵes kann demnach eine derart groƟe Beschleunigung auf die Masse 20 ausĆ¼ben, dass diese den Sog Ć¼berwindet und ans gegenĆ¼ber liegende Ende der Kammer 16 katapultiert wird. Bei entsprechender Wahl der Materialien von Kammer 16 und beweglicher Masse 20 kann in der Schwungphase ein annƤhernd ideal elastischer StoƟ nach vorne zwischen Masse 20 und Kammer 16 erzeugt werden, wodurch eine maximale Menge an kinetischer Energie freigesetzt wird, die die Bewegung des FuƟes unterstĆ¼tzt bzw. gegebenenfalls die Schrittweite verlƤngert. As soon as the runner lifts his foot off the ground, the reservoir 12 pulls back into its original shape and sucks in air through the hole 26 at the head end 38 of the chamber 16. As a result, the movable mass 20 is also guided back towards the end 42 until it abuts the end 42 of the chamber 16 and is initially held there by the suction generated. In the subsequent swing phase of the foot, the movable mass 20 is ultimately accelerated by the forward movement of the foot from the dorsal end 42 of the chamber 16 to the head end 38 of the chamber 16 until it hits the end thereof. The movement of the foot can therefore exert such a great acceleration on the mass 20 that it overcomes the suction and is catapulted to the opposite end of the chamber 16. With appropriate selection of the materials of chamber 16 and movable mass 20, an approximately ideal elastic forward impact between mass 20 and chamber 16 can be generated in the swing phase, whereby a maximum amount of kinetic energy is released, which supports the movement of the foot or if necessary, extend the step size.
In AbhƤngigkeit von der Orientierung der Kammer 16 - also ob das Kopfende 38 in Laufrichtung nach vorne (Mittel- bis VorderfuƟbereich MB, VB) oder nach hinten (MittelfuƟ- bis Fersenbereich MB, FB) zeigt, kann somit durch die Bewegung der beweglichen Masse 20 jeder Schritt des LƤufers verkĆ¼rzt oder verlƤngert werden. Bezuqszeichenliste Depending on the orientation of the chamber 16 - that is, whether the head end 38 points forward (mid-to-forefoot area MB, VB) or backwards (mid-foot to heel area MB, FB), the movement of the movable mass 20 can thus each step of the runner can be shortened or lengthened.
