Definitions

  • the present invention relates to a device for supporting the locomotion of a user, in particular for varying the step width, with a reservoir, a transmission area and a chamber.
  • the invention also relates to a shoe with at least one upper material and a sole and at least one device according to the invention.
  • shoes soles that are designed in such a way that they ensure maximum energy recovery for the wearer of the shoes.
  • sports shoes that have return springs or the like in the sole designed to improve the responsiveness and energy return of the shoe.
  • shoes with particularly hard and flat soles are also produced in order to achieve more direct contact with the ground and thus speed for the runner.
  • Known systems for changing and / or influencing the footbed are for example from DE 28 00 359 A1 , U.S.A. 4,458,430 and U.S. 2017/071287 A1 known.
  • the systems listed above all have the function of cushioning the shocks that occur naturally when running and returning as much energy as possible to the runner.
  • the shoe sole serves as a cushioning device and deforms more or less with every step depending on the elasticity of the sole. After the runner lifts their foot again, the sole is designed in such a way that ideally it completely resumes the shape of the initial, non-loaded state. The acceleration of the runner and the running behavior of the runner should be supported by the restoring force of the sole.
  • the object of the present invention is to provide a shoe that improves energy recovery when a user moves.
  • a further object of the present invention is to provide a shoe that makes it possible to influence the running performance of a user in such a way that he can achieve better performance, for example in competition. It is another object of the present invention to provide a low cost training shoe.
  • the device according to the invention for supporting the movement of a user, in particular for varying the step width, with a reservoir, a transfer area and a chamber is characterized in that the reservoir is designed to be pressurized and the transfer area is designed to transmit a pressure wave emanating from the reservoir into the chamber. When the pressure is released, a negative pressure is generated in the reservoir and the opposite effect is achieved.
  • the device is thus based on the principle of the transmission of pressure waves.
  • a pressure wave is generated, which is transported via the transmission area in the direction of the chamber and thus moves along the device until it strikes one end of the device. After the impact has ended, a negative pressure forms in the reservoir, which has the opposite effect.
  • 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 sagittal plane of the user.
  • a step size of a user can thus be lengthened or shortened in a targeted manner.
  • a pressure wave that is directed backwards and upwards, viewed in the running direction can support the heel lift of a runner, while a pressure wave that impedes the push-off of the foot at the time the heel vibrates towards the buttocks, makes the running movement more difficult in a targeted manner.
  • the step size of a user can be shortened, for example for training purposes, in order to increase the load during training.
  • the alignment of the device can then be selected, for example in competition, in such a way that a step size is increased, so that the user needs fewer steps for the same distance.
  • the chamber has a cavity, the cavity containing at least one movable mass.
  • the pressure wave generated in the reservoir hits the moving mass in the chamber, causing it to move Movement and shifts the position of the moving mass in the cavity. This happens in relation to the ground contact or flight phases of the user.
  • Kinetic energy is converted into potential energy when the movable mass is moved and pushed towards one of the two ends of the cavity. When the moving mass hits the end of the device, this energy is then released again as kinetic energy.
  • the reservoir is no longer pressurised, the reservoir produces the opposite effect and pulls the movable mass back in the direction of the reservoir and initially holds it there by the suction produced.
  • the suction has to be strong enough to hold the mass at the corresponding end of the chamber, even if the foot of the user is tilted in such a way that the head end of the chamber is pointing away from the body - ie downwards.
  • the toes of the corresponding foot then usually point backwards towards the ground.
  • the movement towards the reservoir of the moving mass occurs during the lifting of the user's foot.
  • the moving mass is thrown again from the dorsal end of the chamber to the opposite head end until it hits the head end of the chamber. This occurs during the last phase of the foot's swing, when the foot is swung forward past the center of gravity and the runner's other foot is already back on the ground.
  • the energy released in this way can then contribute to a more dynamic, possibly longer step.
  • the movement of the movable mass can be controlled in a targeted manner by applying pressure to or subsequently releasing the reservoir.
  • the moving mass is located at the rear in the running direction before the movement phase of the foot. At this moment pushes the mass to the dorsal end of the chamber, aiding backward and upward movement. Therefore, an energetic effect in the dorsocranial direction is to be expected.
  • the mass is initially moved to the ventral end of the chamber, which initially has no effect during the foot's contact with the ground. The mass is then moved in the direction of the dorsal end due to the suction generated after the ground contact has ended and is held there until the foot enters the swing phase, during which the mass then overcomes the suction or the suction ends and the mass is thrown forward as far as possible .
  • 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 filled completely or only partially with the medium.
  • the medium is a fluid, in particular a gas such as air or a fluid with a high viscosity, and/or a solid body, in particular a foam-like substance, for example a particularly open-pored PU foam matrix.
  • a foam for example, at least part of the device can be manufactured inexpensively.
  • a foam matrix for example, 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 means of suction.
  • the device is or can be arranged on the user's foot, at least in sections, parallel to a running surface of the foot. It has proven to be advantageous for both the reservoir and the chamber if they are at least partially parallel to the running surface of the Foot can be arranged. By arranging the reservoir parallel to the running surface, the user's foot can effectively exert pressure on the reservoir without the user or runner feeling disturbed by the device in his running behavior or being negatively influenced by it.
  • the chamber has an elongate, in particular tubular, shape.
  • 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.
  • the predetermined direction of movement of the movable mass corresponds to a longitudinal direction (ie in the sagittal plane).
  • the predetermined direction of movement of the movable mass corresponds to the direction of movement of the foot during movement.
  • the energy released is thus also directed in a certain direction, so that the energy regained when running, walking, jumping, etc. can be used in a targeted manner to increase performance (longer strides) or reduce performance (shorter strides).
  • the latter could be used in training, for example, to achieve similar effects as in so-called parachute or toboggan training.
  • This "negativeā€ effect is somewhat similar to that of a well-known Slofit 3D-printed training shoe ("The Gritā€), which destabilizes the user with each step to simulate walking on sand, thus increasing resistance while running.
  • the advantage of the present invention is the possibility of adjusting the "loadā€ so that it can be adjusted as needed.
  • the present invention is not intended to throw the user off balance, for example in order to strengthen the ankle muscles, but rather to specifically ā€œbrakeā€ the running movement.
  • a spring or the like can be provided at the head end of the chamber, for example, if the "negative" effect is to be achieved.
  • This spring holds the moving mass at the head end, which may be ventral with respect to the foot, until the corresponding foot is forward in swing phase.
  • This spring can then catapult the mass backwards to the dorsal end in order to disrupt the swing phase and thereby minimize the stride.
  • the head of the chamber can also be located dorsally, so that the mass is initially thrown backwards.
  • the suction that is generated by the reservoir after lifting the foot then pulls the mass back forward (ventral) and holds it there.
  • 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 exactly this point in time, this can lead to a minimization of the step size.
  • the chamber is preferably formed at least in sections from a rigid material, in particular aluminum. This is to ensure that when the moving mass hits the end of the chamber, a maximum amount of energy is released in the form of kinetic energy. At the same time, the material shouldn't be too heavy either, since it has generally been shown that shoes are perceived as more comfortable, more effective and better by runners the less weight they have. It is known that one reduces A weight saving of 100g reduces the oxygen requirements of an average runner by 1%.
  • the longitudinal extent of the chamber corresponds at least essentially to a running direction parallel to a longitudinal direction of the running surface.
  • 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 allows, for example, an improvement in a shot when kicking a ball, such as occurs in soccer.
  • the longitudinal extension of the chamber corresponds at least essentially to a running direction transverse to the longitudinal direction of the tread. It should thus be possible to use the recovered energy 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 speed skating.

  • 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 moving mass performs an almost ideally elastic impact at the respective end of the device, so that a maximum amount 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.

Die Erfindung betrifft ferner einen Schuh mit zumindest einem Obermaterial und einer Sohle und zumindest einer erfindungsgemƤƟen Vorrichtung.The invention also 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 Materialien und Verfahren fĆ¼r die Herstellung der Sohlen und Obermaterialien der Schuhe ausgewƤhlt.In the development of shoes, especially in the field of running, more and more value is being placed on optimizing the foot load, the rolling behavior of the foot and the performance of the shoe. Appropriate materials and processes are selected for the manufacture of the soles and uppers of the shoes.

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 EnergierĆ¼ckgabe des Schuhs zu verbessern. Zum selben Zweck werden auch Schuhe mit besonders harten und flachen Sohlen hergestellt, um einen direkteren Bodenkontakt 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. Likewise, there are sports shoes that have return springs or the like in the sole designed to improve the responsiveness and energy return of the shoe. For the same purpose, shoes with particularly hard and flat soles are also produced in order to achieve more direct contact with the ground and thus 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 gewƤhrleisten und damit einen verbesserten Komfort bieten kƶnnen.On the other hand, other systems that are provided in the soles of the shoes are designed in such a way that they can provide more cushioning for the feet of the runners and thus offer improved comfort.

Bekannte Systeme zum VerƤndern und/oder Beeinflussen der FuƟbettung sind beispielsweise aus der DE 28 00 359 A1 , US 4 458 430 A und US 2017/071287 A1 bekannt.Known systems for changing and / or influencing the footbed are for example from DE 28 00 359 A1 , U.S.A. 4,458,430 and U.S. 2017/071287 A1 known.

Die oben aufgelisteten Systeme haben prinzipiell alle die Funktion, die beim Laufen natĆ¼rlich auftretenden StĆ¶ĆŸe abzufedern und mƶglichst viel der Energie an den LƤufer zurĆ¼ckzugeben. Die Schuhsohle dient dabei als DƤmpfungsmittel und deformiert 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 des LƤufers sollen durch die RĆ¼ckstellkraft der Sohle unterstĆ¼tzt werden.In principle, the systems listed above all have the function of cushioning the shocks that occur naturally when running and returning as much energy as possible to the runner. The shoe sole serves as a cushioning device and deforms more or less with every step depending on the elasticity of the sole. After the runner lifts their foot again, the sole is designed in such a way that ideally it completely resumes the shape of the initial, non-loaded state. 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 Aufgabe der vorliegenden Erfindung einen kostengĆ¼nstigen Trainingsschuh bereitzustellen.The object of the present invention is to provide a shoe that improves energy recovery when a user moves. A further object of the present invention is to provide a shoe that makes it possible to influence the running performance of a user in such a way that he can achieve better performance, for example in competition. It is another object of the present invention to provide a low cost 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 10 gelƶst.This object is achieved by a device for assisting the locomotion of a user with the features of claim 1 and by a shoe with the features of claim 10.

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 Reservoir dazu ausgebildet ist, mit Druck beaufschlagt zu werden und der Ɯbertragungsbereich dazu ausgebildet ist, eine von dem Reservoir ausgehende Druckwelle in die Kammer zu Ć¼bertragen. Beim Lƶsen der Beaufschlagung wird ein Unterdruck im Reservoir erzeugt und damit der gegenteilige Effekt erzielt.The device according to the invention for supporting the movement of a user, in particular for varying the step width, with a reservoir, a transfer area and a chamber is characterized in that the reservoir is designed to be pressurized and the transfer area is designed to transmit a pressure wave emanating from the reservoir into the chamber. When the pressure is released, a negative pressure is generated in the reservoir and the opposite effect is achieved.

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 Vorrichtung stĆ¶ĆŸt. Nach Beendigung der Beaufschlagung bildet sich im Reservoir ein Unterdruck, wodurch der gegenteilige Effekt erzielt wird. Damit wird eine Druckwelle in Richtung des Reservoirs bewegt und somit gewissermaƟen ein Sog erzeugt mittels dem ein auf die Kammer ausgeĆ¼bter Druck wieder entfernt werden kann. Die Bewegung der Druckwelle geschieht dabei hauptsƤchlich in der Sagittalebene des Benutzers.The device is thus based on the principle of the transmission of pressure waves. In this case, by applying pressure to the reservoir, a pressure wave is generated, which is transported via the transmission area in the direction of the chamber and thus moves along the device until it strikes one end of the device. After the impact has ended, a negative pressure forms in the reservoir, which has the opposite effect. 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 sagittal plane of the user.

Je nach Richtung der Druckwelle in oder entgegen einer Laufrichtung des Benutzers 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 werden, 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 Belastung im Training zu erhƶhen. Umgekehrt kann dann bspw. im Wettkampf die Ausrichtung 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 walking direction of the user, a step size of a user can thus be lengthened or shortened in a targeted manner. For example, a pressure wave that is directed backwards and upwards, viewed in the running direction, can support the heel lift of a runner, while a pressure wave that impedes the push-off of the foot at the time the heel vibrates towards the buttocks, makes the running movement more difficult in a targeted manner. Through a targeted variation of the step size, the step size of a user can be shortened, for example for training purposes, in order to increase the load during training. Conversely, the alignment of the device can then be selected, for example in competition, in such a way that a step size is increased, so that the user needs fewer steps for the same distance.

ErfindungsgemƤƟ 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 umgewandelt. 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 gegenteiligen 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 Benutzers derart geneigt ist, dass das Kopfende der Kammer vom Kƶrper weg - also nach unten - zeigt. Dies entspricht jener Schrittphase, in der sich der FuƟ des LƤufers in Laufrichtung betrachtet hinter (dorsal) dem Kƶrperschwerpunkt 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 Benutzers. Bei der anschlieƟenden Flugphase bzw. der Schwungphase des FuƟes wird die bewegliche Masse wieder von dem dorsalen Ende der Kammer an das gegenĆ¼berliegende 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 the invention, the chamber has a cavity, the cavity containing at least one movable mass. Thus, the pressure wave generated in the reservoir hits the moving mass in the chamber, causing it to move Movement and shifts the position of the moving mass in the cavity. This happens in relation to the ground contact or flight phases of the user. Kinetic energy is converted into potential energy when the movable mass is moved and pushed towards one of the two ends of the cavity. When the moving mass hits the end of the device, this energy is then released again as kinetic energy. When the reservoir is no longer pressurised, the reservoir produces the opposite effect and pulls the movable mass back in the direction of the reservoir and initially holds it there by the suction produced. Thus, the suction has to be strong enough to hold the mass at the corresponding end of the chamber, even if the foot of the user is tilted in such a way that the head end of the chamber is pointing away from the body - ie downwards. This corresponds to the step phase in which the runner's foot is located behind (dorsal) the body's center of gravity, viewed in the running direction. The toes of the corresponding foot then usually point backwards towards the ground. The movement towards the reservoir of the moving mass occurs during the lifting of the user's foot. During the subsequent flight phase or swing phase of the foot, the moving mass is thrown again from the dorsal end of the chamber to the opposite head end until it hits the head end of the chamber. This occurs during the last phase of the foot's swing, when the foot is swung forward past the center of gravity and the runner's other foot is already back on the ground.

Die somit freigegebene Energie kann dann zu einem dynamischeren, gegebenenfalls auch lƤngeren Schritt beitragen. Durch das Beaufschlagen bzw. das anschlieƟende Lƶsen des Reservoirs mit Druck, kann die Bewegung der beweglichen Masse gezielt gesteuert werden.The energy released in this way can then contribute to a more dynamic, possibly longer step. The movement of the movable mass can be controlled in a targeted manner by applying pressure to or subsequently releasing the reservoir.

Dadurch kann es einerseits erreicht werden, dass sich die bewegliche Masse vor der Bewegungsphase des FuƟes in Laufrichtung hinten befindet. In diesem Moment stĆ¶ĆŸt die Masse an das dorsale Ende der Kammer und unterstĆ¼tzt die Bewegung nach hinten und oben. Daher ist ein energetischer Effekt in dorsokranialer Richtung zu erwarten.As a result, on the one hand it can be achieved that the moving mass is located at the rear in the running direction before the movement phase of the foot. At this moment pushes the mass to the dorsal end of the chamber, aiding backward and upward movement. Therefore, an energetic effect in the dorsocranial direction is to be expected.

Andererseits kann es auch erreicht werden, dass die Masse zunƤchst an das ventrale 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 maximal weit nach vorne geschleudert wird.On the other hand, it can also be achieved that the mass is initially moved to the ventral end of the chamber, which initially has no effect during the foot's contact with the ground. The mass is then moved in the direction of the dorsal end due to the suction generated after the ground contact has ended and is held there until the foot enters the swing phase, during which the mass then overcomes the suction or the suction ends and the mass is thrown forward as far as possible .

GemƤƟ einem AusfĆ¼hrungsbeispiel ist das Reservoir mit zumindest einem Medium gefĆ¼llt. Das Medium sorgt dafĆ¼r, dass eine ausreichend groƟe Druckwelle erzeugt 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 filled completely or only partially with the medium.

Es ist denkbar, dass das Medium ein Fluid, insbesondere ein Gas wie beispielsweise Luft oder ein Fluid mit hoher ViskositƤt, und/oder ein Festkƶrper, insbesondere ein schaumartiger Stoff, bspw. eine insbesondere offenporige PU Schaummatrix ist. Durch die Verwendung bspw. eines Schaumstoffs kann zumindest ein Teil der Vorrichtung kostengĆ¼nstig hergestellt werden. AuƟerdem kann beispielsweise 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 body, in particular a foam-like substance, for example a particularly open-pored PU foam matrix. By using a foam, for example, at least part of the device can be manufactured inexpensively. In addition, a foam matrix, for example, 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 means of suction.

GemƤƟ einer Variante ist die Vorrichtung am FuƟ des Benutzers zumindest abschnittsweise parallel zu einer LaufflƤche des FuƟes angeordnet oder anordenbar. Sowohl beim Reservoir als auch bei der Kammer hat es sich als vorteilhaft erwiesen, wenn diese jeweils zumindest abschnittsweise parallel zur LaufflƤche des FuƟes anordenbar sind. Durch eine parallele Anordnung des Reservoirs zur LaufflƤche kann effektiv Druck durch den FuƟ des Benutzers auf das Reservoir ausgeĆ¼bt werden, ohne dass der Benutzer bzw. LƤufer sich in seinem Laufverhalten von der Vorrichtung gestƶrt fĆ¼hlt oder durch diese negativ beeinflusst wird.According to one variant, the device is or can be arranged on the user's foot, at least in sections, parallel to a running surface of the foot. It has proven to be advantageous for both the reservoir and the chamber if they are at least partially parallel to the running surface of the Foot can be arranged. By arranging the reservoir parallel to the running surface, the user's foot can effectively exert pressure on the reservoir without the user or runner feeling disturbed by the device in his running behavior or being negatively influenced by it.

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 beweglichen Masse geometrisch vorgegeben.According to a further variant, the chamber has an elongate, in particular tubular, shape. By constraining the movement of the moveable mass to an elongated cavity, the direction of movement of the moveable mass is geometrically dictated.

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 angeordnet, 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 Laufen, Gehen, Springen usw. wiedergewonnene Energie gezielt fĆ¼r eine Leistungssteigerung (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 Zugschlittentraining 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 vorliegenden 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".If the chamber is also arranged parallel to the running surface, for example, the predetermined 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 movement. The energy released is thus also directed in a certain direction, so that the energy regained when running, walking, jumping, etc. can be used in a targeted manner to increase performance (longer strides) or reduce performance (shorter strides). The latter could be used in training, for example, to achieve similar effects as in so-called parachute or toboggan training. This "negative" effect is somewhat similar to that of a well-known adidas 3D-printed training shoe ("The Grit"), which destabilizes the user with each step to simulate walking on sand, thus increasing resistance while running. The advantage of the present invention, however, is the possibility of adjusting the "load" so that it can be adjusted as needed. In addition, the present invention is not intended to throw the user off balance, for example in order to strengthen the ankle muscles, but rather to specifically "brake" the running movement.

In diesem Zusammenhang ist zu bemerken, dass am Kopfende der Kammer beispielsweise 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.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 "negative" effect is to be achieved. This spring holds the moving mass at the head end, which may be ventral with respect to the foot, until the corresponding foot is forward in swing phase. This spring can then catapult the mass backwards to the dorsal end in order to disrupt the swing phase and thereby minimize the stride.

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 of the chamber can also be located dorsally, so that the mass is initially thrown backwards. The suction that is generated by the reservoir after lifting the foot then pulls the mass back forward (ventral) 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 exactly this point in time, this can lead to a minimization of the step size.

Vorzugsweise ist die Kammer zumindest abschnittsweise aus einem starren Material, 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 werden, je weniger Gewicht sie aufweisen. Bekannterweise reduziert nƤmlich eine Gewichtsersparnis von 100g den Sauerstoffbedarf eines durchschnittlichen LƤufers um 1%.The chamber is preferably formed at least in sections from a rigid material, in particular aluminum. This is to ensure that when the moving mass hits the end of the chamber, a maximum amount of energy is released in the form of kinetic energy. At the same time, the material shouldn't be too heavy either, since it has generally been shown that shoes are perceived as more comfortable, more effective and better by runners the less weight they have. It is known that one reduces A weight saving of 100g reduces the oxygen requirements of an average runner by 1%.

GemƤƟ einer AusfĆ¼hrungsform stimmt die LƤngserstreckung der Kammer zumindest im Wesentlichen mit einer Laufrichtung parallel zu einer LƤngsrichtung der LaufflƤche Ć¼berein. Durch eine solche Anordnung der Kammer kann die wiedergewonnene Energie gezielt fĆ¼r eine Leistungssteigerung bzw. fĆ¼r eine Leistungsminimierung ausgenĆ¼tzt werden.According to one embodiment, the longitudinal extent of the chamber corresponds at least essentially to a running direction parallel to a longitudinal direction of the running surface. By arranging the chamber in this way, the recovered energy can be used in a targeted manner for increasing or minimizing performance.

In diesem Zusammenhang ist anzumerken, dass die LƤngserstreckung der Kammer 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 allows, for example, an improvement in a shot when kicking a ball, such as occurs in soccer.

GemƤƟ einer alternativen AusfĆ¼hrungsform stimmt die LƤngserstreckung der Kammer zumindest im Wesentlichen mit einer Laufrichtung quer zu der LƤngsrichtung der LaufflƤche Ć¼berein. Somit soll die wiedergewonnene Energie bei Sportarten genutzt werden kƶnnen, bei denen der FuƟ des Benutzers im Wesentlichen senkrecht zur Laufrichtung steht, wie es zum Beispiel in der Beschleunigungsphase beim Eishockey oder beim Eisschnelllauf der Fall ist.According to an alternative embodiment, the longitudinal extension of the chamber corresponds at least essentially to a running direction transverse to the longitudinal direction of the tread. It should thus be possible to use the recovered energy 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 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.Preferably, the movable mass is reciprocally movable 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.

ErfindungsgemƤƟ 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.According to the invention, the moving mass is one or more spheres or has another geometric shape. Thus, for example, the ball or balls moves back and forth at least essentially in the longitudinal direction or transverse direction of the chamber or obliquely in the chamber.

Es ist denkbar, dass der Durchmesser der Kugel bzw. der mehreren Kugeln jeweils im Bereich von 0,2 bis 20mm liegt, vorzugsweise im Bereich von 1 bis 10mm.It is conceivable that the diameter of the sphere or of the plurality of spheres is in the range from 0.2 to 20 mm, preferably in the range from 1 to 10 mm.

Bevorzugt ist die bewegliche Masse aus einem starren Material, insbesondere aus Stahl, geformt. Es wƤre aber auch mƶglich, dass die Kugel aus anderen Materialien wie beispielsweise Quecksilber geformt ist. Idealerweise fĆ¼hrt die bewegliche Masse somit einen annƤhernd ideal elastischen StoƟ am jeweiligen Ende der Vorrichtung aus, damit maximal viel Energie in Form von kinetischer Energie freigesetzt wird und so wenig wie mƶglich Energie in Form von Deformationen der Materialen usw. verloren geht.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 moving mass performs an almost ideally elastic impact at the respective end of the device, so that a maximum amount 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.

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 vorgesehen, 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 can always be equated with a density wave, since the pressure wave propagates in air (i.e. a gas). In order 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 resume its initial state.

GemƤƟ einer weiteren AusfĆ¼hrungsform ist zumindest eine AuƟenwand des Reservoirs 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 Ausgangszustand zurĆ¼ckformen, damit dabei eine weitere, sich in eine entgegengesetzte Richtung 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. The elastic material can deform when pressure is applied and thus generate a pressure wave inside the reservoir. However, the material can then return to its original state without external influences, so that another wave moving in the opposite direction can be sucked in by the reservoir.

Vorzugsweise umfasst das Reservoir eine Silikonkammer. Eine aus Silikon gefertigte 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 beeinflussen.Preferably the reservoir comprises a silicon chamber. A chamber made of silicone can be produced inexpensively and, in connection with its filling, e.g. a PU foam matrix, can positively influence both the desired cushioning in the sole and the desired generation of the pressure wave.

Vorzugsweise ist der Ɯbertragungsbereich aus einem flexiblen Material geformt. Somit kann die Vorrichtung individuell an den jeweiligen Benutzer oder den jeweiligen Schuh angepasst werden.Preferably the transfer portion is 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 elongate shape. An extension or an elongated shape of the transfer area makes it possible for the reservoir and the chamber to be located at two different locations on the shoe, for example. 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, it is thus possible to choose freely in which orientation to the running direction 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 hoses. A hose has the advantage 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 tubes can all originate from a single reservoir and open into a common chamber. However, it would also be conceivable for a chamber to be arranged on each hose and for the device to therefore have a plurality of chambers.

Eine weitere AusfĆ¼hrungsform sieht es auch vor, dass zwei oder mehrere Reservoirs vorgesehen sind. Diese kƶnnen jeweils einzelne Ɯbertragungsbereiche aufweisen, die in eine gemeinsame Kammer oder in jeweils einzelne Kammern mĆ¼nden 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.A further embodiment also provides for two or more reservoirs to be 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 in this embodiment for each reservoir to be followed by a separate tube, which then merges into a single tube 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 zumindest eine erfindungsgemƤƟe Vorrichtung angeordnet oder anordenbar ist. Zumindest 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 made of at least one upper material and a sole is also provided, wherein at least one device according to the invention is or can be arranged in the area of the sole. At least the reservoir should be arranged in the area of the sole in such a way that the wearer of the shoes can exert pressure on the reservoir with his feet while moving.

Vorzugsweise ist das Reservoir an einem VorderfuƟbereich, einem MittelfuƟbereich 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 BedĆ¼rfnissen entsprechend am Schuh anordnen kann. Im Training kann beispielsweise die Anordnung derart gewƤhlt werden, dass die Abfolge der Druckwellen in die verschiedenen Richtungen derart gewƤhlt wird, dass die Schrittweiten minimiert werden. Umgekehrt kann im Wettkampf die Anordnung derart gewƤhlt sein, dass die Vorrichtung die Schrittweiten optimiert bzw. verlƤngert.Preferably, the reservoir is and/or can be arranged in a forefoot area, a midfoot area and/or a heel area of the sole. Depending on which running type a runner corresponds to, the right shoe can be selected that has the reservoir in the appropriate place. It would also be conceivable that the shoe merely represents the basic structure and the runner himself can arrange the device or the several devices on the shoe according to his needs. In training, for example, the arrangement can be chosen such that the sequence of the pressure waves in the different directions is chosen in such a way that the step sizes are minimized. Conversely, in competition, the arrangement can be selected in such a way that the device optimizes or lengthens the step widths.

GemƤƟ einem AusfĆ¼hrungsbeispiel ist das Reservoir ein Bestandteil der Sohle. Schuhsohlen von Sportschuhen bestehen oftmals ohnehin aus mehreren verschiedenen 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.According to one embodiment, the reservoir is part of the sole. Shoe soles of sports shoes often consist of several different layers anyway, some of which are also made of different materials will. It would thus be conceivable for the reservoir to be manufactured directly as part of the sole--for example as a midsole--in order to simplify manufacture.

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 bedient werden. Dies erscheint auch in der Hinsicht besonders vorteilhaft, als dass sich bei vielen LƤufern der Laufstil je nach Geschwindigkeit verƤndert.According to a variant, the reservoir extends over the entire area of the soleplate. With the help of this embodiment, a shoe can be created that can be used uniformly for all types of runners, regardless of whether they are front, middle or heel 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 many runners change their running style depending on their speed.

In einer AusfĆ¼hrungsform stimmt die LƤngserstreckung der Kammer parallel mit der LƤngserstreckung der Sohle Ć¼berein. Somit kann die Bewegung der beweglichen Masse zumindest im Wesentlichen auf die sagittale Ebene des Benutzers reduziert werden.In one embodiment, the length of the chamber is parallel to the length of the sole. Thus, the movement of the moveable mass can be reduced at least substantially to the user's sagittal plane.

In einer weiteren AusfĆ¼hrungsform ist die LƤngserstreckung der Kammer zumindest 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 Beschleunigungsphase beim Eislaufen bei Eishockeyspielern oder EisschnelllƤufern der Fall ist. Andererseits 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 another embodiment, the length of the chamber is at least partially transverse to the length of the sole. Thus, on the one hand, sports can be served in which the user's foot is essentially transverse or also at an angle to the running direction, as is the case with ice hockey players or speed skaters during the acceleration phase when ice skating. On the other hand, it is also conceivable that the moving 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 KomfortgrĆ¼nden sowie aus optischen GrĆ¼nden kann es vorteilhaft sein, wenn die gesamte Vorrichtung in der Sohle der Schuhe eingebettet ist. Somit Ƥhnelt der Schuhe von auƟen einem herkƶmmlichen Schuh. Vorzugsweise ist die Vorrichtung derart in der Sohle angeordnet, dass der TrƤger keinen Unterschied im Tragekomfort zu einem herkƶmmlichen Schuh merkt.The device is advantageously embedded in the sole. For reasons of comfort as well as for aesthetic reasons, it can be advantageous if the entire device is embedded in the sole of the shoe. The shoe thus resembles a conventional shoe from the outside. Preferably, the device is such in the Sole arranged so that the wearer does not notice any difference in wearing comfort compared to a conventional shoe.

GemƤƟ einer AusfĆ¼hrungsform ist eine Ausrichtung, insbesondere eine Neigung, der Kammer einstellbar oder vorbestimmbar. Je nach Laufverhalten, Trainingseinheit oder auch Geschmack soll der TrƤger des Schuhs so damit flexibel eine Neigung der Kammer passend einstellen kƶnnen, um den gewĆ¼nschten Effekt auf das Laufverhalten des Benutzers besser abzustimmen.According to one embodiment, an orientation, in particular an inclination, of the chamber can be adjusted or predetermined. Depending on the running behavior, training session or even taste, the wearer of the shoe should be able to flexibly adjust an inclination of the chamber to better adjust the desired effect on the running behavior of the user.

GemƤƟ einer weiteren AusfĆ¼hrungsform ist die Ausrichtung durch eine Verstellvorrichtung, insbesondere durch eine Stellschraube, einstellbar. Bspw. ist die Verstellvorrichtung derart in dem Schuh angeordnet, dass ein Benutzer vor dem Laufen den Schuh auf die gewĆ¼nschte Neigung einstellen kann, sodass dieser fĆ¼r die gewĆ¼nschte Anwendung voreingestellt wird. Bspw. ist wird bei einem LangstreckenlƤufer 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 set the shoe to the desired inclination before running, so that it is preset for the desired application. For example, a different incline 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 beispielsweise ein eventuell vorhandenes unerwĆ¼nschtes KlickgerƤusch der Masse zu unterdrĆ¼cken, welches beim StoƟ der Masse gegen die KammerwƤnde entsteht. Eine 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 beeinflusst wird, um ein Komprimieren des Reservoirs dennoch zu ermƶglichen.The adjusting device can also be designed in such a way that it serves as an on/off device. Depending on the application, a user can flexibly set whether the device should be active or not on the shoe. For example, the user can leave the device inactive when simply walking, for example in order to suppress any unwanted clicking noise of the mass which is produced 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 when it is switched off it holds the mass in such a way that it cannot move, but the air circulation within the chamber is not influenced in order to still enable the reservoir to be compressed.

Die Erfindung wird nachfolgend rein beispielhaft unter Bezugnahmen auf die Zeichnungen nƤher erlƤutert. In diesen zeigen:

  • Fig. 1 eine schematische Draufsicht einer erfindungsgemƤƟen Vorrichtung;
  • Fig. 2 einen schematischen Schnitt der erfindungsgemƤƟen Vorrichtung; und
  • Fig. 3 einen schematischer Schnitt eines beispielhaften Schuhs.
The invention is explained in more detail below purely by way of example with reference to the drawings. In these show:
  • 1 a schematic plan view of a device according to the invention;
  • 2 a schematic section of the device according to the invention; and
  • 3 a schematic section of an exemplary shoe.

Die in Figur 1 in einer Draufsicht schematisch dargestellte Vorrichtung 10 zur UnterstĆ¼tzung der Fortbewegung eines Benutzers weist ein Reservoir 12, einen Ɯbertragungsbereich 14 in Form eines Schlauchs und eine Kammer 16 auf.In the figure 1 Device 10 for assisting the movement of a user, shown schematically in a top view, 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 Ausgestaltungen 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 angeordnet sein. Ebenso ist es mƶglich, dass mehrere Lƶcher 26 an der Kammer 16 vorgesehen sind.The chamber 16 in the embodiment shown is an elongate tube having a hole 26 at its one end 38 opposite the transfer portion 14 (see Fig 2 ). However, other shapes and configurations for the chamber 16 are also conceivable. Likewise, the hole 26 can also be located on a 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 ermƶglichen, 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 transfer area 14 is intended to make it possible for the reservoir 12 to be placed in principle at any point on the sole 34 of a shoe 30 (see 3 ) can be used regardless of where on 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 ensure that a pressure wave generated in the reservoir 12 can be transported into the chamber 16 or the cavity of the chamber 16 . The transfer 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 Richtung der Kammer 16 ausbreiten kann, um dort die bewegliche Masse in Bewegung zu versetzen.The reservoir 12 is designed in such a way that it can be pressurized if, for example, the runner presses on the reservoir 12 with his foot during a step. The housing of the reservoir 12 and the medium 22 located therein deform and thus generate a pressure wave inside the reservoir 12, which can propagate via the transmission area 14 in the direction of the chamber 16 in order to set the moving 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 beendet 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 anschlieƟenden Schwungbewegung des FuƟes nach vorne wird die bewegliche Masse 20 erneut 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 dynamischeren als auch zu einem schnelleren Laufen fĆ¼hren kann.It is thus conceivable, for example, that the chamber 16 is arranged in such a way 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. Subsequently, the movable mass 20 is pulled back towards the reservoir when the impact is terminated, i.e. when the foot is in that phase of the movement sequence where it pushes the body off the ground obliquely forward. At this point, the foot is behind the body's center of gravity. At this point in time, the mass 20 is held by the suction generated by the reservoir at the rear end of the chamber 16, ie at the heel area FB of the foot. Upon subsequent forward swinging motion of the foot, the movable mass 20 is again moved forward toward the head end 38 of the chamber 16 until it abuts the head end 38 . This can help a runner wearing shoes 30 with the appropriate devices 10 increase their stride due to the energy regained, which can result in both a more dynamic and faster run.

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 gegenteiligen Effekt zu erzielen und damit bewusst ein Widerstand - und somit eine kĆ¼rzere Schrittweite - fĆ¼r den LƤufer zu erzeugen, ist bei dieser AusfĆ¼hrungsform an jenem 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 diesem Fall in Richtung VorderfuƟbereich VB - gesogen wird, so lange festzuhalten, bis sich der FuƟ in der Schwungphase befindet. In dieser anschlieƟenden Schwungphase nach vorne kann die Feder dann die Masse 20 in Richtung Kopfende der Kammer 16 - also in Richtung Fersenbereich FB - katapultieren, sodass der Schritt des Benutzers gezielt verkĆ¼rzt werden kann. Dieser Effekt kann beispielsweise gezielt im Training als spezieller Trainingsreiz eingesetzt werden.Alternatively, it is also possible to arrange the chamber 16 in such a way that the movable mass 20 moves from the forefoot area VB towards the heel area FB with each step. The head end of the chamber 16 is thus located in the heel area FB of the foot. In order to achieve an overall opposite effect and thus deliberately a resistance - and thus a shorter one Increment - for the runner, in this embodiment, a spring (not shown) or the like is provided at that end of the chamber 16 which adjoins the transmission area, which the mass 20, which returns after the loading of the reservoir 12 has ended - in this case in the direction of the forefoot area VB - to hold on until the foot is in the swing phase. In this subsequent forward swing phase, the spring can then catapult the mass 20 in the direction of the head end of the chamber 16ā€”that is, in the direction of the heel area FBā€”so that the step of the user can be shortened in a targeted manner. This effect can, for example, be used specifically in training as a special training stimulus.

Der Fig. 2 ist des Weiteren zu entnehmen, dass das Reservoir 12 mit einem Medium 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 allerdings eine derart hohe ViskositƤt aufweisen, dass sie nicht in den Ɯbertragungsbereich 14 lƤuft, wenn Druck auf das Reservoir 12 ausgeĆ¼bt wird.Of the 2 it can also be seen 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, this must have such a high viscosity that it does not run into the transfer area 14 when pressure is exerted on the reservoir 12 .

Alternativ hierzu kann eine Membran (nicht gezeigt) vorgesehen sein, die es ermƶglicht 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 zusƤtzlich in einem Kissen befindet, welches innerhalb des Reservoirs 12 angeordnet ist, damit sie nicht auslaufen kann.In this regard, however, it would also be conceivable for the liquid 22 to also be located in a cushion which is arranged inside the reservoir 12 so that it cannot leak 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 GehƤuse 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 versetzen. AnschlieƟend ziehen sich die AuƟenwand 28 bzw. die AuƟenwƤnde 28 wieder in ihre Ausgangsposition zurĆ¼ck, damit die Kugel 20 wieder in Richtung des Reservoirs 12 gezogen wird.In order to be able to effectively pressurize 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. Likewise, it is also conceivable that the entire housing of the reservoir 12 is formed from silicone. This allows the reservoir 12 deform when pressure is applied and emit a pressure wave in the direction of the transmission area 14 and thus set the ball 20 in motion. Subsequently, the outer wall 28 or the outer walls 28 pull back into their starting position, so that the ball 20 is pulled in the direction of the reservoir 12 again.

Fig. 3 zeigt einen Schnitt eines schematischen erfindungsgemƤƟen Schuhs 30. In der gezeigten AusfĆ¼hrungsform ist die gesamte Vorrichtung 10 eine Zwischensohle 34A des Schuhs 30 eingebettet, die auch fĆ¼r die DƤmpfung des Schuhs 30 verantwortlich 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 a midsole 34A of the shoe 30, which is also responsible for the cushioning of the shoe 30. Another outsole 34B is positioned below the midsole 34A and is used to provide the shoe 30 with the necessary grip when walking.

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 Orientierung 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 with each compression of the reservoir 12 from the heel area FB towards the metatarsal area MB and is thus transitioned to the next phase. However, it would also be conceivable for the chamber 16 to be embedded in a different orientation in the midsole 34A.

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 Verstellvorrichtung 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.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 adjusted individually by the wearer of the shoes 30. In principle, such an adjusting device 36 can 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 via a simple mechanism (not shown). For example, the chamber 16 can be tilted about a horizontal axis H via the adjustment device 36, so that the head end 38 of the chamber 16 is adjusted closer to the outsole 34B, for example. It would be though it is also conceivable that the chamber 16 is tilted about a vertical axis (not shown) in order to compensate for any foot deformities of the wearer.

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 Richtung 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.When the device 10 according to the invention is used in a shoe 30, pressure is applied via the runner's foot to the reservoir 12 during each step in the ground contact phase of the corresponding foot. This generates a pressure wave which moves across 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 strikes the movable mass 20 and thus sets it in motion.

Sobald der LƤufer den FuƟ vom Boden abhebt, zieht sich das Reservoir 12 in seine 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 Schwungphase des FuƟes wird die bewegliche Masse 20 letztendlich durch die VorwƤrtsbewegung 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 FuƟes 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 retracts to its original shape, sucking 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 in the direction of the end 42 until it hits 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 moveable 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 abuts the end thereof. The movement of the foot can therefore exert such a high acceleration on the mass 20 that it overcomes the suction and is catapulted to the opposite end of the chamber 16 . If the materials of chamber 16 and movable mass 20 are selected appropriately, an almost ideally elastic forward impact can be generated between mass 20 and chamber 16 during the swing phase, which releases a maximum amount of kinetic energy that supports or slows the movement of the foot. if necessary, the increment is extended.

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.Depending on the orientation of the chamber 16 - that is, whether the head end 38 in the running direction to the front (middle to forefoot area MB, VB) or to the rear (Midfoot to heel area MB, FB), each step of the runner can thus be shortened or lengthened by the movement of the movable mass 20 .
