[0022] Fig. la zeigt ein tragbares System 10 zur Muskelkraftunterstützung. Das System 10 umfasst ein Stützelement 12 in Form eines biegsamen Stabes (bspw. eines Stabes aus Metall/ Stahl), dessen unteres Ende an einem Anbindungselement 14 (bspw. einem flexiblen Gurt aus einem textilen Material) befestigt ist (sich abstützt). Das Anbindungselement 14 kann bspw. als Becken oder Beingurt(e) ausgebildet sein, der/die bei Verwendung kraftschlüssig am Körper des Benutzers anliegt/-en. Das System 10 umfasst zudem ein weiteres Anbindungselement 16 (bspw. einem flexiblen Gurt aus einem textilen Material), welches dazu vorgesehen ist, an den Oberkörper des Benutzers angebunden zu werden. Fig. 1a shows a portable system 10 for muscle strength support. The system 10 includes a support member 12 in the form of a flexible rod (eg, a metal / steel rod), the lower end of which is attached (supported) to a tether 14 (eg, a flexible webbing of a textile material). The attachment element 14 may be designed, for example, as a pelvis or leg strap (s), which, when used, rests against the body of the user in a force-fitting manner. The system 10 further comprises a further attachment element 16 (eg a flexible belt made of a textile material), which is intended to be tied to the torso of the user.
[0023] Das weitere Anbindungselement 16 ist mittels einer Linearführung mit dem Stützelement 12 verbunden. Wie aus Fig. la und Fig. lb ersichtlich, erlaubt die Linearführung eine Verschiebung der Anbindungselemente 14, 16 relativ zueinander. Obwohl das Anbindungselement 14 dazu eingerichtet ist, im Wesentlichen fest auf der Hüfte/dem Becken des Benutzers aufzusitzen, wird somit eine Längung des Rückens beim Strecken/Beugen durch das System 10 nicht behindert. Die Linearführung kann bspw. dadurch gebildet sein, dass das Anbindungselement 16 eine Öffnung aufweist, durch die das Stützelement 12 geführt ist. The further connection element 16 is connected by means of a linear guide with the support element 12. As can be seen from FIG. 1a and FIG. 1b, the linear guide permits a displacement of the connecting elements 14, 16 relative to one another. Thus, although the attachment member 14 is configured to substantially substantially rest on the hip / pelvis of the user, elongation of the back during stretching / flexing by the system 10 is not hindered. The linear guide can, for example, be formed in that the connection element 16 has an opening through which the support element 12 is guided.
[0024] Das Anbindungselement 16 kann auf dem Stützelement 12 frei gleitend gelagert sein. Alternativ kann das Anbindungselement 16 mittels eines Aktors 16a entlang der Linearführung (d. h. entlang der Längsachse des Stützelements 12) aktiv (gesteuert) verschiebbar sein. Bspw. kann der Aktor 16a, wie in Fig. lb angedeutet, in das Anbindungselement 16 integriert sein. The connection element 16 may be freely slidably mounted on the support member 12. Alternatively, the attachment element 16 may be actively (controlled) displaceable along the linear guide (i.e., along the longitudinal axis of the support element 12) by means of an actuator 16a. For example. can the actuator 16a, as indicated in Fig. lb, be integrated into the connection element 16.
[0025] Das System 10 umfasst zudem einen Aktor 18, der einen Angriffspunkt oberhalb des Anbindungselement 16 am Stützelement 12 aufweist und es ermöglicht, wie in Fig. tc illustriert, mittels Verkürzung (der freien Länge) eines elastischen Zugmittels 20, das Anbindungselement 16 mit einer Kraft zu beaufschlagen, die der Verformung des Stützelements 12 entgegenwirkt (bzw. entgegengesetzt ist). Dadurch kann über die Steuerung des Aktors 18 die Steifigkeit des Stützelements 12 dynamisch verändert werden. The system 10 further comprises an actuator 18 which has a point of application above the attachment element 16 on the support element 12 and, as illustrated in FIG. 1c, by means of shortening (the free length) of an elastic traction device 20, the attachment element 16 with to act on a force that counteracts (or is opposite) the deformation of the support member 12. As a result, the rigidity of the support element 12 can be changed dynamically via the control of the actuator 18.
[0026] Beugt sich der Benutzer bspw. nach vorne, kann der Aktor 18 das elastisches Zugmittel 20 nachgeben, um das Beugen nicht zu behindern. Muss der Benutzer jedoch beim Aufrichten des Oberkörpers unterstützt werden, bspw. weil der Benutzer eine schwere Last in Händen hält, kann dies durch die Beaufschlagung des elastischen Zugmittels 20 mit einer Kraft (d. h. durch entsprechende Steuerung des Aktors 18) unterstützt werden. [0027] Die Unterstützungskraft wirkt dabei immer in eine Richtung, welche in der von dem Stützelement 12 und dem elastisches Zugmittel 20 aufgespannten Ebene liegt. Bewegungen in eine Richtung, die mit der aufgespannten Ebene einen rechten Winkel einschließt, werden hingegen nicht unterstützt, so dass eine weitgehend uneingeschränkte Bewegungsfreiheit gegeben ist. If the user bends forwards, for example, the actuator 18 can yield the elastic traction means 20, so as not to hinder the bending. However, if the user must be assisted in erecting the upper body, for example, because the user holds a heavy load in his hands, this can be assisted by the application of the elastic traction means 20 with a force (ie, by appropriate control of the actuator 18). The support force always acts in a direction which lies in the plane defined by the support member 12 and the elastic traction means 20 level. Movements in one direction, which includes a right angle with the plane spanned, however, are not supported, so that a largely unrestricted freedom of movement is given.
[0028] Je nach Einsatzzweck können Zugmittel 20 unterschiedlicher Elastizität verwendet werden. Bspw. kann ein Seil oder ein Federelement (bspw. eine Schraubenfeder/Stahlfeder) verwendet werden, das/die (materialbedingt bereits) eine gewünschte Elastizität aufweist. Oder das Seil kann durch in Reihe Schalten mit Federelementen (bspw. Schraubenfedern/Stahlfedern) auf eine gewünschte Elastizität abgestimmt werden. Depending on the purpose of traction means 20 different elasticity can be used. For example. For example, a rope or a spring element (for example a helical spring / steel spring) can be used which has a desired elasticity (due to the material already). Or the rope can be tuned to a desired elasticity by switching in series with spring elements (eg coil springs / steel springs).
[0029] Für die Steuerung des Systems (bzw. des Aktors 18) kann eine Kombination verschiedener Sensoren genutzt werden. Bspw. kann die Lage und Lageänderung des Oberkörpers durch eine Inertial Measurement Unit (IMU) erfasst werden. Weiterhin können Kraftsensoren in die Oberkörperanbindung und den Aktor 18 integriert sein, wodurch es möglich ist, die jeweils aktuelle Belastung und die vorliegende Unterstützungsleistung zu ermitteln. For the control of the system (or the actuator 18), a combination of different sensors can be used. For example. The position and position of the upper body can be detected by an inertial measurement unit (IMU). Furthermore, force sensors can be integrated in the upper body connection and the actuator 18, whereby it is possible to determine the current load and the present support performance.
[0030] Weiterhin kann der Aktor 18 gesteuert/geregelt werden, bspw. mittels eines geschlossenen Regelkreises aus (bspw. einem pneumatischem) Aktuator 18 und einem Druckwandler. Dadurch kann die tatsächliche Kraft, von der die benötigte Unterstützungsleistung abhängt, eingestellt werden. Das System 10 kann ferner einen Energiespeicher (bspw. eine oder mehrere Primär- oder Sekundärzellen und/oder einem oder mehrere Drucklufttanks) umfassen. Furthermore, the actuator 18 can be controlled / regulated, for example by means of a closed loop from (eg. A pneumatic) actuator 18 and a pressure transducer. This can be used to set the actual force on which the required assistance is required. The system 10 may further include an energy store (eg, one or more primary or secondary cells and / or one or more compressed air tanks).
[0031] Fig. 2a zeigt ein weiteres tragbares System 10 zur Muskelkraftunterstützung. Das System 10 umfasst ein Stützelement 12 in Form eines flexiblen, länglichen, luftdichten Elements (bspw. eines versteifbaren und/oder längenverstellbaren Überdruckelements). Das untere Ende des Stützelements 12 ist, wie in Fig. 2b angedeutet, (zur Ermöglichung eines seitlichen Beugens des Rumpfes) mittels eines Drehgelenks 22 an einem Anbindungselement 14 (bspw. einem flexiblen Gurt aus einem textilen Material) und/oder einem weiteren Aktor 24 befestigt. Fig. 2a shows another portable system 10 for muscle strength support. The system 10 includes a support member 12 in the form of a flexible, elongate, airtight member (eg, a stiffenable and / or length adjustable overpressure member). The lower end of the support member 12 is, as indicated in Fig. 2b (to allow lateral bending of the trunk) by means of a hinge 22 at a Attachment element 14 (eg, a flexible belt made of a textile material) and / or another actuator 24 attached.
[0032] Wie in Zusammenhang mit Fig. la, lb und lc beschrieben, kann das Anbindungselement 14 bspw. als Becken-, Bein- oder Fußgurt(e) ausgebildet sein, der/die bei Verwendung kraftschlüssig am Körper des Benutzers anliegt/- en. Das System 10 umfasst zudem ein weiteres Anbindungselement 16 (bspw. einem flexiblen Gurt aus einem textilen Material), welches dazu vorgesehen ist, an den Oberkörper des Benutzers angebunden zu werden. As described in connection with FIGS. 1 a, 1 b and 1 c, the connection element 14 may, for example, be designed as a pelvic, leg or foot strap (e) which, when used, rests against the body of the user in a force-fitting manner , The system 10 also includes another attachment member 16 (eg, a flexible webbing of a textile material) which is intended to be tied to the torso of the user.
[0033] Das System 10 umfasst des Weiteren einen zusätzlichen Aktor 24. Wie in Fig. 2c illustriert ist der Aktor 24 eingerichtet, das Stützelement 12 (linear, parallel zur Wirbelsäule) zu verschieben. Bspw. kann durch das Verschieben des Stützelements 12 nach oben vermieden werden, dass der Benutzer beim Strecken des Oberkörpers behindert wird. Beugt sich der Benutzer hingegen nach vorne, kann das Stützelement 12 nach unten verschoben und Druck aus dem das Stützelement 12 abgelassen werden, um das Beugen nicht zu behindern. The system 10 further includes an additional actuator 24. As illustrated in Figure 2c, the actuator 24 is configured to translate the support member 12 (linear, parallel to the spine). For example. can be avoided by moving the support member 12 upwards that the user is hampered in stretching the upper body. If, on the other hand, the user bends forward, the support element 12 can be displaced downwards and pressure can be released from the support element 12 so as not to hinder bending.
[0034] Muss der Benutzer jedoch beim Aufrichten des Oberkörpers unterstützt werden, bspw. weil der Benutzer eine schwere Last in Händen hält, kann dies durch Befüllen/Aufblasen des Stützelements 12 und Ansteuern des Aktors 24 unterstützt werden. Der Aktor (24) kann somit eingesetzt werden, um zum einen die Unterstützungsposition (Oberkörpervorbeuge) einzustellen und zum anderen das Aufrichten zu unterstützen. Zum Befüllen/Aufblasen des Stützelements 12 ist ein weiterer Aktor und eine Energiequelle vorgesehen (bspw. eine Pumpe oder ein betätigbares Ventil, sowie ein Druckluftbehälter; nicht gezeigt) However, if the user needs assistance in erecting the upper body, for example, because the user holds a heavy load in his hands, this can be aided by filling / inflating the support member 12 and driving the actuator 24. The actuator (24) can thus be used, on the one hand to adjust the support position (Oberkörpervorbeuge) and on the other to support the erection. For filling / inflating the support element 12, a further actuator and an energy source is provided (for example a pump or an actuatable valve, as well as a compressed air tank, not shown).
[0035] Fig. 3 zeigt ein Ablaufdiagramm eines erfindungsgemäßen Verfahrens. Das Verfahren beginnt mit dem Schritt 26 des Anbindens des Systems 10 an den Körper eines Menschen. Wenn, wie in Schritt 28, ein Steuerbefehl empfangen wird, der auf eine Vergrößerung der Steifigkeit des Stützelements 12 gerichtet ist, wird in Schritt 30, in Reaktion auf den Steuerbefehl, die Steifigkeit des Stützelements 12 vergrößert, bspw. mittels Beaufschlagens des oberen Endes des Stützelements 12 mit einer Zugkraft oder durch Befüllen des Stützelements 12 mit Luft. 3 shows a flow chart of a method according to the invention. The method begins with step 26 of attaching the system 10 to the body of a human. If, as in step 28, a control command is received which is directed to an increase in the rigidity of the support member 12, in step 30, in response to the control command, the stiffness of the support member 12 is increased, for example. By applying the upper end of the Support member 12 with a tensile force or by filling the support member 12 with air.
