Definitions

  • the present invention relates to a length adjustment device for a finger movement splint of a therapy device for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand; a finger movement splint for carrying out such a movement with such a length adjustment device and a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand, comprising at least one such finger movement splint.
  • the present invention also relates to a method for adjusting the length of a finger movement splint on a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand.
  • Therapy devices with finger movement splints for the automated movement of individual and/or multiple fingers of a hand enable controlled joint mobilization regardless of the availability of physiotherapy staff. Through automated training that is independent of the time of day and individually tailored to the respective user, such devices improve the success of therapy in a cost-effective manner and shorten the user's recovery time.
  • JP 2011 115 248 A and in the US 2014/028 86 64 A1 Devices for supporting finger movement are disclosed, the movement mechanism of which is arranged laterally next to the respective fingers, so that movement restriction by resting on the finger is avoided.
  • the JP 2011 115 248 A discloses a device for supporting a movement, in particular a finger movement splint, which is said to be able to set a three-joint region to a natural bent position.
  • a finger movement support device which uses sensor technology to determine the user's intention regarding a desired finger movement ("bending or stretching") and then supports this movement with the help of piezoelectric drives arranged on each finger joint.
  • both devices can only be inadequately adapted to the differentiated anatomical shapes of the fingers or thumbs of different patients, which means that the automated movement of the fingers performed by them can deviate relatively significantly from a natural movement.
  • a portable exoskeleton training robot for hand rehabilitation has become known.
  • This training robot includes a fixation device for the hand, which can be attached to the back of the hand and the wrist, and rehabilitation devices for the fingers and thumb.
  • the rehabilitation devices are each driven by linear motors.
  • Threaded rods are available which allow at least manual length adjustment for each individual rehabilitation device.
  • the EN 11 2017 000 012 B4 a therapy device for carrying out a continuous, passive and/or actively assisted movement of the fingers and thumb of a patient's hand, which allows each selected finger to be provided with its own finger movement splint with movement kinematics, which are arranged laterally to the finger to be treated and provide it with a allows for unrestricted bending and/or stretching movements.
  • the well-known finger movement splint is based on a slide-rail movement kinematics, which enables an automated finger movement that is very close to an anatomically natural finger movement.
  • a finger movement splint or a therapy device is described, the movement kinematics of which include a multi-joint hinge as a means of bending a metacarpophalangeal joint and is therefore particularly robust against the effects of axial forces and torsional forces on the finger movement splint.
  • the movement principles of both of the aforementioned publications are hereby expressly referred to in full.
  • the device in particular the individual finger movement splints, must be adjusted to the respective anatomy, i.e. to the hand size and/or the individual finger dimensions, before training begins.
  • the individual finger movement splints are usually attached manually to the upper shell or holder of the respective therapy device in the optimal position for the respective user.
  • the finger movement splints must then be manually removed after a training session and manually reattached in a different place for the next user. This procedure is time-consuming and, in everyday clinical practice, adversely reduces the training time available to the respective user with the therapy device.
  • the object of the present invention is therefore to provide a device or a method which carries out the adaptation of a finger movement splint or a corresponding therapy device to the anatomy of the respective user quickly and cost-effectively in an automated manner.
  • a length adjustment device for a finger movement splint of a therapy device for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand with the features of patent claim 1; by a finger movement splint for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand with the features of patent claim 11; by a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or thumb of a hand with the features of patent claim 12; and by a method for adjusting the length of a finger movement rail on a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or thumb of a hand with the features of patent claim 14.
  • the carriage can preferably be operatively connected directly to the drive.
  • the carriage can also be operatively connected indirectly to the drive via at least one connecting element.
  • An embodiment in which the carriage can be operatively connected directly to the drive, in particular via a direct operative connection to a spindle of the drive, enables a comparatively simple construction of the length adjustment device, whereas an embodiment in which the carriage can be operatively connected indirectly to the drive via at least one connecting element promotes a comparatively compact, in particular flat construction of the length adjustment device.
  • the adjustment rail is preferably a grid track with at least two grid elements.
  • a grid track with at least two grid elements advantageously enables the holding means and thus also the finger movement rail to be locked onto the therapy device in a simple manner.
  • the at least two grid elements protrude from the plane of the adjustment rail in a substantially wedge-shaped (triangular) and/or semicircular and/or in the form of a circular arc triangle (so-called "Reuleaux triangle”).
  • Grid elements that protrude from the plane of the adjustment track in this way advantageously enable positive locking, whereby in the case of a wedge (triangular) shape and/or a semicircular shape and/or the shape of a circular arc triangle (so-called "Reuleaux triangle shape”) the effect of the blocking mechanism can be overcome more easily (with less effort) by exerting force using the slide than would be the case, for example, with grid elements that protrude from the plane in a cuboid shape.
  • the at least two grid elements can also be designed as holes within the adjustment rail.
  • An adjustment rail with holes as grid elements in the sense of a perforated plate advantageously enables a flatter construction of the adjustment rail.
  • the holding means preferably has a first side wall for holding the blocking mechanisms and a second side wall for holding the finger movement rail, which are connected to one another at least via a base element, thereby forming a substantially U-shaped cross section through which the adjustment rail runs.
  • a substantially U-shaped holding means advantageously enables simple and cost-effective production, depending on the material selected, for example by bending a metal sheet, by injection molding or 3D printing. In addition, such a holding means can easily be moved along the adjustment rail as a guide.
  • the adjustment rail comprises a first side wall and a second side wall along its longitudinal axis, wherein the first side wall, the adjustment rail and the second side wall together form a substantially U-shaped cross section, and wherein the holding means is arranged to be movable within the substantially U-shaped cross section with respect to the adjustment rail.
  • the blocking mechanisms each comprise at least one fixing means arranged on the holding means, preferably on the first side wall; a blocking lever pivoted on the holding means, preferably on the first side wall, via a rotation axis; and a means for springing the blocking lever relative to the fixing means, wherein the blocking lever is designed such that when the carriage comes into operative connection with the blocking lever, the blocking lever is rotated from a blocking position to an unblocking position and the holding means is thereby movable in at least one direction.
  • a blocking mechanism advantageously enables a change in position of the holding means caused by the carriage and thus the drive of the finger movement rail and the the finger movement rail held by the holding device along the adjustment rail on the therapy device.
  • the blocking mechanisms can also be designed as a single piece and made from a resilient material, in particular spring steel and/or hard rubber.
  • the fixing means and the blocking levers can advantageously be made from a single piece of resilient material, with the blocking levers being arranged at an angle to the fixing means and the intersection points between the blocking levers and the fixing means corresponding to the axes of rotation.
  • the means for suspension can be replaced by the spring properties of the resilient material, in particular the spring steel and/or the hard rubber, itself, which advantageously saves one component per blocking mechanism and reduces the size of the blocking mechanism.
  • the blocking levers are operatively connected to the adjustment rail in their respective blocking position, in particular to the grid elements of an adjustment rail designed as a grid track, and in their respective unblocking position are not operatively connected to the adjustment rail, in particular to the grid elements of an adjustment rail designed as a grid track. If the blocking levers are operatively connected to the adjustment rail, in particular to the grid elements of an adjustment rail designed as a grid track, a movement of the holding means along the adjustment rail is advantageously prevented and the finger movement rail is held stable and securely in one position so that the therapy movement can be carried out safely.
  • the holding means can advantageously be moved along the adjustment rail to any position or, in the case of an adjustment rail designed as a grid track, to a position depending on the grid elements or the holes.
  • the present invention also relates to a finger movement splint for performing a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand, comprising a length adjustment device according to one of claims 1 to 10.
  • the present invention also relates to a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand, comprising at least one drive for a finger movement rail and at least one finger movement rail according to claim 11.
  • the drive is a linear drive, in particular a spindle motor, a pneumatic cylinder, a hydraulic cylinder and/or a cable pull.
  • a linear drive advantageously enables a controlled movement of the carriage and thus both the finger movement rail during the execution of the therapy movement and the holding means together with the finger movement rail during length adjustment along the adjustment rail.
  • the present invention relates to a method for adjusting the length of a finger movement rail on a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand, which is characterized in that a connecting element of a finger movement rail arranged on a holding means is moved with the aid of a drive via a carriage along an adjustment rail from an amplitude for a therapy movement into a first or second adjustment range; wherein the carriage, when moved by means of the drive in a first direction along the adjustment rail into the first adjustment range, exerts a force on the first blocking mechanism upon contact with a first blocking mechanism, so that the first blocking mechanism is released and the holding means together with the finger movement rail is moved by movement of the carriage in the first direction, and wherein the carriage, when moved by means of the drive in a second direction along the adjustment rail into the second adjustment range, exerts a force on the second blocking mechanism upon contact with a second blocking mechanism, so that the second blocking mechanism is released and the holding means together with the finger
  • a length adjustment device advantageously makes it possible to automatically move a finger movement rail along an adjustment rail using the drive already present for the finger movement rail on a therapy device and to fix it in a desired position - depending on the finger length or hand size/length of the user - on the adjustment rail and thus on the therapy device in order to then be able to carry out a continuous, passive and/or actively assisted movement of a finger and/or thumb of a hand in a stable position.

Description

Die vorliegende Erfindung betrifft eine Längeneinstellvorrichtung für eine FingerBewegungsschiene eines Therapiegeräts zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung eines Fingers und/oder eines Daumens einer Hand; eine Finger-Bewegungsschiene zur Durchführung einer derartigen Bewegung mit einer solchen Längeneinstellvorrichtung sowie ein Therapiegerät zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung wenigstens eines Fingers und/oder eines Daumens einer Hand, umfassend wenigstens eine solche FingerBewegungsschiene.The present invention relates to a length adjustment device for a finger movement splint of a therapy device for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand; a finger movement splint for carrying out such a movement with such a length adjustment device and a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand, comprising at least one such finger movement splint.

Darüber hinaus betrifft die vorliegende Erfindung auch ein Verfahren zur Längeneinstellung einer Finger-Bewegungsschiene auf einem Therapiegerät zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung wenigstens eines Fingers und/oder eines Daumens einer Hand.Furthermore, the present invention also relates to a method for adjusting the length of a finger movement splint on a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand.

Therapiegeräte mit Finger-Bewegungsschienen zur automatisierten Bewegung einzelner und/oder mehrerer Finger einer Hand ermöglichen eine kontrollierte Gelenkmobilisation unabhängig von der Verfügbarkeit von physiotherapeutischem Personal. Durch ein tageszeitunabhängiges und individuell auf den jeweiligen Benutzer abgestelltes automatisiertes Training, verbessern derartige Geräte auf kostengünstige Weise den Therapieerfolg und verkürzen die Genesungszeit des Benutzers.Therapy devices with finger movement splints for the automated movement of individual and/or multiple fingers of a hand enable controlled joint mobilization regardless of the availability of physiotherapy staff. Through automated training that is independent of the time of day and individually tailored to the respective user, such devices improve the success of therapy in a cost-effective manner and shorten the user's recovery time.

Bislang sind eine Reihe von derartigen Therapie- und Trainingsgeräten bekannt geworden, welche sich u.a. in der Art und Weise, wie auf die Fingergelenke der Finger automatisiert Kraft ausgeübt wird, unterscheiden. In der JP 2011 115 248 A und in der US 2014/028 86 64 A1 werden Vorrichtungen zur Unterstützung einer Fingerbewegung offenbart, deren Bewegungsmechanismus seitlich neben den jeweiligen Fingern angeordnet sind, sodass eine Bewegungseinschränkung durch Aufliegen auf dem Finger vermieden wird. Die JP 2011 115 248 A offenbart dabei eine Vorrichtung zur Unterstützung einer Bewegung, insbesondere eine Finger-Bewegungsschiene, welche in der Lage sein soll eine Drei-Gelenk-Region auf eine natürliche gebogene Haltung zu setzen. In der US 2014/0288664 A1 ist dagegen eine Fingerbewegungsunterstützungsvorrichtung offenbart, welche mittels Sensortechnik die Intention des Benutzers bezüglich einer gewünschten Fingerbewegung ("Beugen oder Strecken") ermittelt und diese Bewegung dann mit Hilfe von an jedem Fingerglied angeordneten piezoelektrischen Antrieben unterstützt.So far, a number of such therapy and training devices have become known, which differ, among other things, in the way in which force is automatically exerted on the finger joints. JP 2011 115 248 A and in the US 2014/028 86 64 A1 Devices for supporting finger movement are disclosed, the movement mechanism of which is arranged laterally next to the respective fingers, so that movement restriction by resting on the finger is avoided. The JP 2011 115 248 A discloses a device for supporting a movement, in particular a finger movement splint, which is said to be able to set a three-joint region to a natural bent position. In the US 2014/0288664 A1 In contrast, a finger movement support device is disclosed which uses sensor technology to determine the user's intention regarding a desired finger movement ("bending or stretching") and then supports this movement with the help of piezoelectric drives arranged on each finger joint.

Beide Vorrichtungen lassen sich allerdings aufgrund ihres Bauprinzips nur unzureichend an die differenzierten anatomischen Formen der Finger bzw. Daumen verschiedener Patienten anpassen, wodurch die durch sie ausgeführte automatisierte Bewegung der Finger von einer natürlichen Bewegung relativ stark abweichen kann.However, due to their design, both devices can only be inadequately adapted to the differentiated anatomical shapes of the fingers or thumbs of different patients, which means that the automated movement of the fingers performed by them can deviate relatively significantly from a natural movement.

Weitere Finger-Bewegungsschienen bzw. Hand-Therapiegeräte sind aus der CN 108 814 898 A und der KR 2019 001 19 26 A1 bekannt geworden.Further finger movement splints and hand therapy devices are available from CN 108 814 898 A and the KR 2019 001 19 26 A1 became known.

Aus der CN 105 726 263 A ist in diesem Zusammenhang ein tragbarer Exoskelett-Trainingsroboter zur Rehabilitation der Hand bekannt geworden. Dieser Trainingsroboter umfasst eine Fixierungsvorrichtung für die Hand, welche am Handrücken und am Handgelenk befestigt werden kann, und Rehabilitationsvorrichtungen für die Finger und für den Daumen. Die Rehabilitationsvorrichtungen werden jeweils durch Linearmotoren angetrieben. Zur Anpassung des Trainingsroboter an die anatomischen Gegebenheiten des jeweiligen Benutzers, sieht die CN 105 726 263 A Gewindestangen vor, welche bei jeder einzelnen Rehabilitationsvorrichtung zumindest eine manuelle Längenanpassung ermöglichen.From the CN 105 726 263 A In this context, a portable exoskeleton training robot for hand rehabilitation has become known. This training robot includes a fixation device for the hand, which can be attached to the back of the hand and the wrist, and rehabilitation devices for the fingers and thumb. The rehabilitation devices are each driven by linear motors. To adapt the training robot to the anatomical conditions of the respective user, the CN 105 726 263 A Threaded rods are available which allow at least manual length adjustment for each individual rehabilitation device.

Zur Verbesserung dessen wurde in der DE 11 2017 000 012 B4 ein Therapiegerät zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung der Finger und des Daumens der Hand eines Patienten offenbart, welches es erlaubt, jedem gewählten Finger eine eigene Finger-Bewegungsschiene mit Bewegungskinematiken zur Verfügung zu stellen, die seitlich des zu behandelnden Fingers angeordnet diesem eine behinderungsfreie Beuge und/oder Streckbewegung gestattet. Die bekannte FingerBewegungsschiene basiert auf einer Schlitten-Schiene-Bewegungskinematik, welche eine automatisierte Fingerbewegung ermöglicht, die einer anatomisch natürlichen Fingerbewegung sehr nahe kommt. Alternativ dazu wurde in der DE 10 2019 112 049.7 eine Finger-Bewegungsschiene beziehungsweise ein Therapiegerät beschrieben, dessen Bewegungskinematik ein Mehrgelenkscharnier als Mittel zur Beugung eines Fingergrundgelenks umfasst und dadurch insbesondere robust gegenüber der Einwirkung axialer Kräfte sowie von Torsionskräften auf die Finger-Bewegungsschiene ist. Auf die Bewegungsprinzipien beider vorgenannten Druckschriften wird hiermit ausdrücklich vollumfänglich Bezug genommen.To improve this, the EN 11 2017 000 012 B4 a therapy device for carrying out a continuous, passive and/or actively assisted movement of the fingers and thumb of a patient's hand, which allows each selected finger to be provided with its own finger movement splint with movement kinematics, which are arranged laterally to the finger to be treated and provide it with a allows for unrestricted bending and/or stretching movements. The well-known finger movement splint is based on a slide-rail movement kinematics, which enables an automated finger movement that is very close to an anatomically natural finger movement. Alternatively, in the EN 10 2019 112 049.7 a finger movement splint or a therapy device is described, the movement kinematics of which include a multi-joint hinge as a means of bending a metacarpophalangeal joint and is therefore particularly robust against the effects of axial forces and torsional forces on the finger movement splint. The movement principles of both of the aforementioned publications are hereby expressly referred to in full.

Bei allen derartigen Therapiegeräten muss vor Beginn des Trainings eine Anpassung des Geräts, insbesondere der einzelnen Finger-Bewegungsschienen, an die jeweilige Anatomie, also an die Handgröße und/oder die einzelnen Fingerabmessungen, durchgeführt werden. Dazu werden die einzelnen Finger-Bewegungsschienen zumeist manuell auf der Oberschale bzw. Halterung des jeweiligen Therapiegeräts in der für den jeweiligen Benutzer optimalen Position befestigt, die Finger-Bewegungsschienen müssen nach einer Trainingseinheit dann manuell gelöst und für den nächsten Benutzer an anderer Stelle wiederum manuell neu befestigt werden. Diese Prozedur ist zeitaufwendig und verkürzt im Klinikalltag nachteilig die für den jeweiligen Benutzer zur Verfügung stehende Trainingszeit mit dem Therapiegerät.For all such therapy devices, the device, in particular the individual finger movement splints, must be adjusted to the respective anatomy, i.e. to the hand size and/or the individual finger dimensions, before training begins. To do this, the individual finger movement splints are usually attached manually to the upper shell or holder of the respective therapy device in the optimal position for the respective user. The finger movement splints must then be manually removed after a training session and manually reattached in a different place for the next user. This procedure is time-consuming and, in everyday clinical practice, adversely reduces the training time available to the respective user with the therapy device.

Aufgabe der vorliegenden Erfindung ist es deshalb, eine Vorrichtung bzw. ein Verfahren bereitzustellen, welche die Anpassung einer Finger-Bewegungsschiene bzw. eines entsprechenden Therapiegeräts an die Anatomie des jeweiligen Benutzers schnell und kostengünstig automatisiert durchführt.The object of the present invention is therefore to provide a device or a method which carries out the adaptation of a finger movement splint or a corresponding therapy device to the anatomy of the respective user quickly and cost-effectively in an automated manner.

Diese Aufgabe wird durch eine Längeneinstellvorrichtung für eine FingerBewegungsschiene eines Therapiegeräts zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung eines Fingers und/oder eines Daumens einer Hand mit den Merkmalen des Patentanspruchs 1; durch eine Finger-Bewegungsschiene zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung eines Fingers und/oder eines Daumens einer Hand mit den Merkmalen des Patentanspruchs 11; durch ein Therapiegerät zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung wenigstens eines Fingers und/oder eines Daumens einer Hand mit den Merkmalen des Patentanspruchs 12; sowie durch ein Verfahren zur Längeneinstellung einer Finger-Bewegungsschiene auf einem Therapiegerät zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung wenigstens eines Fingers und/oder eines Daumens einer Hand mit den Merkmalen des Patentanspruchs 14 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen, welche jeweils einzeln oder in Kombination miteinander einsetzbar sind, sind Gegenstand der abhängigen Ansprüche.This object is achieved by a length adjustment device for a finger movement splint of a therapy device for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand with the features of patent claim 1; by a finger movement splint for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand with the features of patent claim 11; by a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or thumb of a hand with the features of patent claim 12; and by a method for adjusting the length of a finger movement rail on a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or thumb of a hand with the features of patent claim 14.

Eine erfindungsgemäße Längeneinstellvorrichtung umfasst:

  • wenigstens eine Einstellschiene;
  • wenigstens ein, bezüglich der Einstellschiene bewegbares Haltemittel zur Halterung der Finger-Bewegungsschiene;
  • wenigstens einen ersten, am Haltemittel angeordneten, Blockierungsmechanismus zur Blockierung der Bewegung des Haltemittels in eine erste Richtung entlang der Einstellschiene;
  • wenigstens einen zweiten, am Haltemittel angeordneten, Blockierungsmechanismus zur Blockierung der Bewegung des Haltemittels in eine zweite Richtung entlang der Einstellschiene;
  • wenigstens einen Schlitten,
    • wobei der Schlitten über wenigstens ein Verbindungselement mit der Finger-Bewegungsschiene wirkverbindbar ist;
    • wobei der Schlitten eingerichtet ist, mittels eines Antriebs zur Bewegung der Finger-Bewegungsschiene, entlang der Einstellschiene bewegt zu werden;
  • wobei der Schlitten so ausgelegt ist, dass, wenn er mittels des Antriebs in die erste Richtung entlang der Einstellschiene bewegt wird, bei Kontakt mit dem ersten Blockierungsmechanismus eine Kraft auf den ersten Blockierungsmechanismus ausübt, sodass der erste Blockierungsmechanismus gelöst und das Haltemittel mitsamt der Finger-Bewegungsschiene durch Bewegung des Schlittens in die erste Richtung bewegbar ist;
  • und wobei der Schlitten so ausgelegt ist, dass, wenn er mittels des Antriebs in die zweite Richtung entlang der Einstellschiene bewegt wird, bei Kontakt mit dem zweiten Blockierungsmechanismus eine Kraft auf den zweiten Blockierungsmechanismus ausübt, sodass der zweite Blockierungsmechanismus gelöst und das Haltemittel mitsamt der Finger-Bewegungsschiene durch Bewegung des Schlittens in die zweite Richtung bewegbar ist.
A length adjustment device according to the invention comprises:
  • at least one adjustment rail;
  • at least one holding means movable relative to the adjustment rail for holding the finger movement rail;
  • at least one first blocking mechanism arranged on the holding means for blocking the movement of the holding means in a first direction along the adjustment rail;
  • at least one second blocking mechanism arranged on the holding means for blocking the movement of the holding means in a second direction along the adjustment rail;
  • at least one sleigh,
    • wherein the carriage is operatively connectable to the finger movement rail via at least one connecting element;
    • wherein the carriage is adapted to be moved along the adjustment rail by means of a drive for moving the finger movement rail;
  • wherein the carriage is designed such that when it is moved in the first direction along the adjustment rail by means of the drive, upon contact with the first blocking mechanism it exerts a force on the first blocking mechanism so that the first blocking mechanism is released and the holding means together with the finger movement rail can be moved in the first direction by moving the carriage;
  • and wherein the carriage is designed such that when it is moved by means of the drive in the second direction along the adjustment rail, upon contact with the second blocking mechanism, a force is exerted on the second blocking mechanism so that the second blocking mechanism is released and the holding means together with the finger movement rail can be moved in the second direction by moving the carriage.

In einer ersten Ausgestaltung der Längeneinstellvorrichtung kann der Schlitten vorzugsweise unmittelbar mit dem Antrieb wirkverbindbar sein. In einer dazu alternativen, bevorzugten Ausgestaltung kann der Schlitten auch mittelbar über wenigstens ein Verbindungselement mit dem Antrieb wirkverbindbar sein. Eine Ausgestaltung bei der der Schlitten unmittelbar mit dem Antrieb wirkverbindbar ist, insbesondere über eine direkte Wirkverbindung zu einer Spindel des Antriebs, ermöglicht eine vergleichsweise einfache Konstruktion der Längeneinstellvorrichtung, wohingegen eine Ausgestaltung bei der der Schlitten mittelbar über wenigstens ein Verbindungselement mit dem Antrieb wirkverbindbar eine vergleichsweise kompakte, insbesondere flache Bauweise der Längeneinstellvorrichtung begünstigt.In a first embodiment of the length adjustment device, the carriage can preferably be operatively connected directly to the drive. In an alternative, preferred embodiment, the carriage can also be operatively connected indirectly to the drive via at least one connecting element. An embodiment in which the carriage can be operatively connected directly to the drive, in particular via a direct operative connection to a spindle of the drive, enables a comparatively simple construction of the length adjustment device, whereas an embodiment in which the carriage can be operatively connected indirectly to the drive via at least one connecting element promotes a comparatively compact, in particular flat construction of the length adjustment device.

In einer weiteren Ausgestaltung ist die Einstellschiene vorzugsweise eine Rasterbahn mit wenigsten zwei Rasterelementen. Eine Rasterbahn mit wenigstens zwei Rasterelementen ermöglicht vorteilhaft auf einfache Weise das Arretieren des Haltemittels und damit auch der Finger-Bewegungsschiene auf dem Therapiegerät.In a further embodiment, the adjustment rail is preferably a grid track with at least two grid elements. A grid track with at least two grid elements advantageously enables the holding means and thus also the finger movement rail to be locked onto the therapy device in a simple manner.

Dabei ist bevorzugt, dass die wenigstens zwei Rasterelemente im Wesentlichen keilförmig (dreieckig) und/oder halbkreisförmig und/oder in Form eines Kreisbogendreiecks (sog. "Reuleaux-Dreieck") aus der Ebene der Einstellschiene herausragen. Rasterelemente, die auf diese Weise aus der Ebene der Einstellbahn herausragen, ermöglichen vorteilhaft ein formschlüssiges Arretieren, wobei bei einer Keil (Dreicks-)form und/oder einer Halbkreisform und/oder der Form eines Kreisbogendreiecks (sog. "Reuleaux-Dreiecksform") die Wirkung des Blockierungsmechanismus durch Kraftausübung mittels des Schlittens einfacher (mit weniger Kraftaufwand) überwunden werden kann als es beispielsweise bei quaderförmig aus der Ebene herausragenden Rasterelementen der Fall wäre.It is preferred that the at least two grid elements protrude from the plane of the adjustment rail in a substantially wedge-shaped (triangular) and/or semicircular and/or in the form of a circular arc triangle (so-called "Reuleaux triangle"). Grid elements that protrude from the plane of the adjustment track in this way advantageously enable positive locking, whereby in the case of a wedge (triangular) shape and/or a semicircular shape and/or the shape of a circular arc triangle (so-called "Reuleaux triangle shape") the effect of the blocking mechanism can be overcome more easily (with less effort) by exerting force using the slide than would be the case, for example, with grid elements that protrude from the plane in a cuboid shape.

Alternativ dazu können die wenigstens zwei Rasterelemente auch als Löcher innerhalb der Einstellschiene ausgestaltet sein. Eine Einstellschiene mit Löchern als Rasterelementen im Sinne einer Lochplatte ermöglicht vorteilhaft eine flachere Bauweise der Einstellschiene.Alternatively, the at least two grid elements can also be designed as holes within the adjustment rail. An adjustment rail with holes as grid elements in the sense of a perforated plate advantageously enables a flatter construction of the adjustment rail.

In einer weiteren Ausgestaltung weist das Haltemittel vorzugsweise eine erste Seitenwand zur Halterung der Blockierungsmechanismen und eine zweite Seitenwand zur Halterung der Finger-Bewegungsschiene auf, welche wenigstens über ein Bodenelement miteinander verbunden sind, wodurch sich ein im Wesentlichen U-förmiger Querschnitt bildet, durch den die Einstellschiene verläuft. Ein im Wesentlichen U-förmig ausgestaltetes Haltemittel ermöglicht vorteilhaft eine einfache und kostengünstige Herstellung, je nach gewähltem Material zum Beispiel durch Biegen eines Metallblechs, durch Spritzguss oder 3D-Druck. Zudem lässt sich ein derartiges Haltemittel problemlos entlang der Einstellschiene als Führung verschieben.In a further embodiment, the holding means preferably has a first side wall for holding the blocking mechanisms and a second side wall for holding the finger movement rail, which are connected to one another at least via a base element, thereby forming a substantially U-shaped cross section through which the adjustment rail runs. A substantially U-shaped holding means advantageously enables simple and cost-effective production, depending on the material selected, for example by bending a metal sheet, by injection molding or 3D printing. In addition, such a holding means can easily be moved along the adjustment rail as a guide.

In einer alternativen Ausführungsform hat es sich bewährt, wenn die Einstellschiene entlang ihrer Längsachse eine erste Seitenwand und eine zweite Seitenwand umfasst, wobei die erste Seitenwand, die Einstellschiene und die zweite Seitenwand zusammen einen im Wesentlichen U-förmigen Querschnitt bilden, und wobei das Haltemittel innerhalb des im Wesentlichen U-förmigen Querschnitts bezüglich der Einstellschiene bewegbar angeordnet ist. Eine derartige Ausführung führt vorteilhaft zu einer besonders flachen Bauweise der Längeneinstellvorrichtung und somit zu geringem Platzbedarf auf innerhalb einer Finger-Bewegungsschiene bzw. auf einem Therapiegerät.In an alternative embodiment, it has proven useful if the adjustment rail comprises a first side wall and a second side wall along its longitudinal axis, wherein the first side wall, the adjustment rail and the second side wall together form a substantially U-shaped cross section, and wherein the holding means is arranged to be movable within the substantially U-shaped cross section with respect to the adjustment rail. Such an embodiment advantageously leads to a particularly flat design of the length adjustment device and thus to a small space requirement within a finger movement rail or on a therapy device.

Erfindungsgemäß bevorzugt ist darüber hinaus eine Ausgestaltung der Längeneinstellvorrichtung, bei der die Blockierungsmechanismen jeweils wenigstens ein am Haltemittel, vorzugsweise an der ersten Seitenwand, angeordnetes Fixiermittel; einen, über eine Drehachse drehbar am Haltemittel, vorzugsweise an der ersten Seitenwand, angelenkten Blockierungshebel; und ein Mittel zur Federung des Blockierungshebels gegenüber dem Fixiermittel umfassen, wobei der Blockierungshebel so ausgelegt ist, dass, wenn der Schlitten mit dem Blockierungshebel in Wirkverbindung tritt, der Blockierungshebel von einer Blockierungsposition in eine Deblockierungsposition gedreht wird und das Haltemittel dadurch in wenigstens eine Richtung bewegbar ist. Ein derartiger Blockierungsmechanismus ermöglicht vorteilhaft eine durch den Schlitten und damit den Antrieb der Finger-Bewegungsschiene bewirkte Positionsänderung des Haltemittels und der durch das Haltemittel gehaltenen Finger-Bewegungsschiene entlang der Einstellschiene auf dem Therapiegerät.According to the invention, a design of the length adjustment device is also preferred in which the blocking mechanisms each comprise at least one fixing means arranged on the holding means, preferably on the first side wall; a blocking lever pivoted on the holding means, preferably on the first side wall, via a rotation axis; and a means for springing the blocking lever relative to the fixing means, wherein the blocking lever is designed such that when the carriage comes into operative connection with the blocking lever, the blocking lever is rotated from a blocking position to an unblocking position and the holding means is thereby movable in at least one direction. Such a blocking mechanism advantageously enables a change in position of the holding means caused by the carriage and thus the drive of the finger movement rail and the the finger movement rail held by the holding device along the adjustment rail on the therapy device.

Alternativ dazu können die Blockierungsmechansimen auch einteilig ausgebildet und aus einem federnden Material, insbesondere Federstahl und/oder Hartgummi gebildet sein. Dabei können vorteilhaft die Fixiermittel und die Blockierungshebel aus einem einzigen Stück federndem Material gebildet werden, wobei die Blockierungshebel gegenüber den Fixiermitteln abgewinkelt angeordnet sein und die Schnittpunkte zwischen den Blockierungshebeln und den Fixiermitteln den Drehachsen entsprechen können. In dieser Ausgestaltungsform können die Mittel zur Federung durch die Federeigenschaften des federnden Materials, insbesondere des Federstahls und/oder des Hartgummis, selbst ersetzt werden, wodurch vorteilhaft jeweils ein Bauteil pro Blockierungsmechanismus eingespart und die Größe des Blockierungsmechanismus reduziert werden kann.Alternatively, the blocking mechanisms can also be designed as a single piece and made from a resilient material, in particular spring steel and/or hard rubber. The fixing means and the blocking levers can advantageously be made from a single piece of resilient material, with the blocking levers being arranged at an angle to the fixing means and the intersection points between the blocking levers and the fixing means corresponding to the axes of rotation. In this embodiment, the means for suspension can be replaced by the spring properties of the resilient material, in particular the spring steel and/or the hard rubber, itself, which advantageously saves one component per blocking mechanism and reduces the size of the blocking mechanism.

Zudem hat sich eine Ausgestaltung bewährt, bei der die Blockierungshebel in ihrer jeweiligen Blockierungsposition mit der Einstellschiene, insbesondere mit den Rasterelementen einer als Rasterbahn ausgebildeten Einstellschiene, in Wirkverbindung sind und in ihrer jeweiligen Deblockierungsposition mit der mit der Einstellschiene, insbesondere mit den Rasterelementen einer als Rasterbahn ausgebildeten Einstellschiene, nicht in Wirkverbindung sind. Wenn die Blockierungshebel mit der Einstellschiene, insbesondere mit den Rasterelementen einer als Rasterbahn ausgebildeten Einstellschiene, in Wirkverbindung sind, wird eine Verfahrbewegung des Haltemittels entlang der Einstellschiene vorteilhaft verhindert und die Fingerbewegungsschiene stabil und sicher an einer Position gehalten, so dass die Therapiebewegung sicher ausgeführt werden kann. Sind die Blockierungshebel nicht in Wirkverbindung mit der Einstellschiene, insbesondere mit den Rasterelementen einer als Rasterbahn ausgebildeten Einstellschiene; so kann das Haltemittel vorteilhaft entlang der Einstellschiene an eine beliebige Position oder, im Fall einer als Rasterbahn ausgebildeten Einstellschiene, an eine Position in Abhängigkeit der Rasterelemente oder der Löcher verfahren werden.In addition, a design has proven to be useful in which the blocking levers are operatively connected to the adjustment rail in their respective blocking position, in particular to the grid elements of an adjustment rail designed as a grid track, and in their respective unblocking position are not operatively connected to the adjustment rail, in particular to the grid elements of an adjustment rail designed as a grid track. If the blocking levers are operatively connected to the adjustment rail, in particular to the grid elements of an adjustment rail designed as a grid track, a movement of the holding means along the adjustment rail is advantageously prevented and the finger movement rail is held stable and securely in one position so that the therapy movement can be carried out safely. If the blocking levers are not operatively connected to the adjustment rail, in particular to the grid elements of an adjustment rail designed as a grid track, the holding means can advantageously be moved along the adjustment rail to any position or, in the case of an adjustment rail designed as a grid track, to a position depending on the grid elements or the holes.

Die vorliegende Erfindung betrifft auch eine Finger-Bewegungsschiene zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung eines Fingers und/oder eines Daumens einer Hand, umfassend eine Längeneinstellvorrichtung nach einem der Ansprüche 1 bis 10.The present invention also relates to a finger movement splint for performing a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand, comprising a length adjustment device according to one of claims 1 to 10.

Die vorliegende Erfindung betrifft zudem ein Therapiegerät zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung wenigstens eines Fingers und/oder eines Daumens einer Hand, umfassend wenigstens einen Antrieb für eine Finger-Bewegungsschiene und wenigstens eine Finger-Bewegungsschiene nach Anspruch 11.The present invention also relates to a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand, comprising at least one drive for a finger movement rail and at least one finger movement rail according to claim 11.

Dabei ist in einer Ausgestaltung des Therapiegeräts bevorzugt, dass der Antrieb ein linearer Antrieb, insbesondere ein Spindelmotor, ein Pneumatikzylinder, ein Hydraulikzylinder und/oder ein Seilzug, ist. Ein linearer Antrieb ermöglicht vorteilhaft eine kontrollierte Bewegung des Schlittens und damit sowohl der Finger-Bewegungsschiene während der Durchführung der Therapiebewegung als auch des Haltemittels nebst FingerBewegungsschiene während Längeneinstellung entlang der Einstellschiene.In one embodiment of the therapy device, it is preferred that the drive is a linear drive, in particular a spindle motor, a pneumatic cylinder, a hydraulic cylinder and/or a cable pull. A linear drive advantageously enables a controlled movement of the carriage and thus both the finger movement rail during the execution of the therapy movement and the holding means together with the finger movement rail during length adjustment along the adjustment rail.

Schließlich betrifft die vorliegende Erfindung ein Verfahren zur Längeneinstellung einer Finger-Bewegungsschiene auf einem Therapiegerät zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung wenigstens eines Fingers und/oder eines Daumens einer Hand, welches sich dadurch auszeichnet, dass ein Verbindungselement einer, an einem Haltemittel angeordneten Finger-Bewegungsschiene mit Hilfe eines Antriebs über einen Schlitten entlang einer Einstellschiene aus einer Amplitude für eine Therapiebewegung in einen ersten oder zweiten Einstellbereich bewegt wird; wobei der Schlitten, wenn er mittels des Antriebs in eine erste Richtung entlang der Einstellschiene in den ersten Einstellbereich bewegt wird, bei Kontakt mit einem ersten Blockierungsmechanismus eine Kraft auf den ersten Blockierungsmechanismus ausübt, sodass der erste Blockierungsmechanismus gelöst und das Haltemittel mitsamt der FingerBewegungsschiene durch Bewegung des Schlittens in die erste Richtung bewegt wird und wobei der Schlitten, wenn er mittels des Antriebs in eine zweite Richtung entlang der Einstellschiene in den zweiten Einstellbereich bewegt wird, bei Kontakt mit einem zweiten Blockierungsmechanismus eine Kraft auf den zweiten Blockierungsmechanismus ausübt, sodass der zweite Blockierungsmechanismus gelöst und das Haltemittel mitsamt der Finger-Bewegungsschiene durch Bewegung des Schlittens in die zweite Richtung bewegt wird.Finally, the present invention relates to a method for adjusting the length of a finger movement rail on a therapy device for carrying out a continuous, passive and/or actively assisted movement of at least one finger and/or a thumb of a hand, which is characterized in that a connecting element of a finger movement rail arranged on a holding means is moved with the aid of a drive via a carriage along an adjustment rail from an amplitude for a therapy movement into a first or second adjustment range; wherein the carriage, when moved by means of the drive in a first direction along the adjustment rail into the first adjustment range, exerts a force on the first blocking mechanism upon contact with a first blocking mechanism, so that the first blocking mechanism is released and the holding means together with the finger movement rail is moved by movement of the carriage in the first direction, and wherein the carriage, when moved by means of the drive in a second direction along the adjustment rail into the second adjustment range, exerts a force on the second blocking mechanism upon contact with a second blocking mechanism, so that the second blocking mechanism is released and the holding means together with the finger movement rail is moved by movement of the carriage in the second direction.

Eine erfindungsgemäße Längeneinstellvorrichtung bzw. ein erfindungsgemäßes Verfahren zur Längeneinstellung ermöglicht es vorteilhaft, eine Finger-Bewegungsschiene mit Hilfe des für die Finger-Bewegungsschiene auf einem Therapiegerät bereits vorhandenen Antriebs entlang einer Einstellschiene automatisch zu verschieben und an einer gewünschten Position - in Abhängigkeit der Fingerlänge bzw. Handgröße/länge des Benutzers - auf der Einstellschiene und damit auf dem Therapiegerät zu fixieren, um dann in einer stabilen Position eine kontinuierliche, passive und/oder aktiv-assistierte Bewegung eines Fingers und/oder eines Daumens einer Hand durchführen zu können. Ein zeitaufwendiges manuelles Einstellen ist dadurch vorteilhaft vermieden.A length adjustment device according to the invention or a method according to the invention for length adjustment advantageously makes it possible to automatically move a finger movement rail along an adjustment rail using the drive already present for the finger movement rail on a therapy device and to fix it in a desired position - depending on the finger length or hand size/length of the user - on the adjustment rail and thus on the therapy device in order to then be able to carry out a continuous, passive and/or actively assisted movement of a finger and/or thumb of a hand in a stable position. Time-consuming manual adjustment is thus advantageously avoided.

Fig. 1 zeigt eine Ausgestaltung einer erfindungsgemäßen Längeneinstellvorrichtung 3 in einer perspektivischen Darstellung. Die Längeneinstellvorrichtung 3 für eine FingerBewegungsschiene 2 eines Therapiegeräts 1 zur Durchführung einer kontinuierlichen, passiven und/oder aktiv-assistierten Bewegung eines Fingers und/oder eines Daumens einer Hand, umfasst dabei wenigstens eine Einstellschiene 30; wenigstens ein, bezüglich der Einstellschiene 30 bewegbares Haltemittel 34 zur Halterung der FingerBewegungsschiene 2; wenigstens einen ersten, am Haltemittel 34 angeordneten, Blockierungsmechanismus 31 zur Blockierung der Bewegung des Haltemittels 34 in eine erste Richtung B1 entlang der Einstellschiene 30 und wenigstens einen zweiten, am Haltemittel 34 angeordneten, Blockierungsmechanismus 32 zur Blockierung der Bewegung des Haltemittels 34 in eine zweite Richtung B2 entlang der Einstellschiene 30. Fig.1 shows an embodiment of a length adjustment device 3 according to the invention in a perspective view. The length adjustment device 3 for a finger movement rail 2 of a therapy device 1 for carrying out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand comprises at least one adjustment rail 30; at least one holding means 34 that can be moved with respect to the adjustment rail 30 for holding the finger movement rail 2; at least one first blocking mechanism 31 arranged on the holding means 34 for blocking the movement of the holding means 34 in a first direction B1 along the adjustment rail 30 and at least one second blocking mechanism 32 arranged on the holding means 34 for blocking the movement of the holding means 34 in a second direction B2 along the adjustment rail 30.

Fig. 2 zeigt einen Teil einer Längeneinstellvorrichtung 3 nach Fig. 1 mit einem Blockierungshebel 312 in einer Deblockierungsposition P2. Fig. 2 shows a part of a length adjustment device 3 according to Fig.1 with a blocking lever 312 in a release position P2.

Wie in Fig. 1 und 2 gezeigt, kann das Haltemittel 34 vorzugsweise eine erste Seitenwand 341 zur Halterung der Blockierungsmechanismen 31 und 32 und eine zweite Seitenwand 342 zur Halterung der Finger-Bewegungsschiene 2 aufweisen, welche wenigstens über ein Bodenelement 343 miteinander verbunden sind, wodurch sich ein im Wesentlichen U-förmiger Querschnitt bildet, durch den die Einstellschiene 30 verläuft.As in Fig. 1 and 2 As shown, the holding means 34 may preferably have a first side wall 341 for holding the blocking mechanisms 31 and 32 and a second side wall 342 for holding the finger movement rail 2, which are connected to one another at least via a base element 343, thereby forming a substantially U-shaped cross section through which the adjustment rail 30 extends.

Darüber hinaus umfasst die erfindungsgemäße Längeneinstellvorrichtung 3 wenigstens einen Schlitten 33, wobei der Schlitten 33 über wenigstens ein Verbindungselement 20a bzw. 20b (vgl. Fig. 6) mit der Finger-Bewegungsschiene 2 wirkverbindbar ist und wobei der Schlitten 33 eingerichtet ist, mittels eines Antriebs 10 zur Bewegung der FingerBewegungsschiene 2, entlang der Einstellschiene 30 bewegt zu werden. Wie bspw. in den Fig. 1 und 2 gezeigt, kann der Schlitten 33 dazu unmittelbar mit dem Antrieb 10, insbesondere durch eine direkte Wirkverbindung mit einer Spindel 102 des Antriebs 10, wirkverbunden sein. Der Schlitten 33 ist dabei erfindungsgemäß so ausgelegt, dass, wenn er mittels des Antriebs 10 in die erste Richtung B1 entlang der Einstellschiene 30 bewegt wird, bei Kontakt mit dem ersten Blockierungsmechanismus 31 eine Kraft auf den ersten Blockierungsmechanismus 31 ausübt, sodass der erste Blockierungsmechanismus 31 gelöst und das Haltemittel 34 mitsamt der Finger-Bewegungsschiene 2 durch Bewegung des Schlittens 30 in die erste Richtung B1 bewegbar ist.In addition, the length adjustment device 3 according to the invention comprises at least one carriage 33, wherein the carriage 33 is connected to the length adjustment device 3 via at least one connecting element 20a or 20b (cf. Fig.6 ) is operatively connected to the finger movement rail 2 and wherein the carriage 33 is arranged to be moved along the adjustment rail 30 by means of a drive 10 for moving the finger movement rail 2. As shown for example in the Fig. 1 and 2 shown, the carriage 33 can be directly connected to the drive 10, in particular by a direct operative connection with a spindle 102 of the drive 10. The carriage 33 is designed according to the invention such that when it is moved by means of the drive 10 in the first direction B1 along the adjustment rail 30, upon contact with the first blocking mechanism 31, it exerts a force on the first blocking mechanism 31, so that the first blocking mechanism 31 is released and the holding means 34 together with the finger movement rail 2 can be moved by moving the carriage 30 in the first direction B1.

Die Fig. 3a und 3b zeigen eine derartige Bewegung des Haltemittels 34 entlang der Einstellschiene 30 in die erste Richtung B1.The Fig. 3a and 3b show such a movement of the holding means 34 along the adjustment rail 30 in the first direction B1.

Zum Bewegen des Haltemittels 34 entlang der Einstellschiene 30 von einer auf der Einstellschiene 30 fixierten Betriebsposition zu einer anderen und damit zur Längeneinstellung der Finger-Bewegungsschiene 2 wird ein Verbindungselement 20a bzw. 20b (vgl. Fig. 6) einer, an einem Haltemittel 34 angeordneten Finger-Bewegungsschiene 2 mit Hilfe eines Antriebs 10, insbesondere mittels der durch den Motor 101 des Antriebs 10 angetriebenen Spindel 102, über einen Schlitten 33 entlang einer Einstellschiene 30 aus einer Amplitude A1 für eine Therapiebewegung in einen ersten A2 oder zweiten A3 Einstellbereich bewegt. Dabei übt der Schlitten 33, wenn er mittels des Antriebs 10, insbesondere mittels der durch den Motor 101 des Antriebs 10 angetriebenen Spindel 102, in eine erste Richtung B1 entlang der Einstellschiene 30 in den ersten Einstellbereich A2 bewegt wird, bei Kontakt mit einem ersten Blockierungsmechanismus 31 eine Kraft auf den ersten Blockierungsmechanismus 31 aus, sodass der erste Blockierungsmechanismus 31 gelöst und das Haltemittel 34 mitsamt der Finger-Bewegungsschiene 2 durch Bewegung des Schlittens 30 in die erste Richtung B1 bewegt wird. Der Blockierungshebel 312 wird, wie in Fig. 2 zu sehen, durch einen Gleitfuß 331 des Schlittens 33 von der Einstellschiene 30 bzw. deren Rasterelementen 31 gegen die Federkraft des Mittels 313 zur Federung wegbewegt, wodurch die Wechselwirkung zwischen Blockierungshebel 312 und Einstellschiene 30 aufgehoben und eine Bewegung des Schlittens 33 samt Haltemittel 34 und Finger-Bewegungsschiene 2 ermöglicht wird. In der hier gezeigten Ausgestaltung kann der Schlitten 33 zwei Gleitfüße 331 und ein die Gleitfüße 331 miteinander verbindendes Querelement 332 umfassen, so dass der Schlitten 33 in der Draufsicht insbesondere eine H-förmige Gestalt aufweisen kann. Der Blockierungshebel 322 des zweiten Blockierungsmechanismus 32 blockiert die Bewegung des Haltemittels 34 in die erste Richtung B1 nicht, sondern lässt sich einfach durch das vom Schlitten 33 bewegte Haltemittel 34 mitziehen.In order to move the holding means 34 along the adjustment rail 30 from one operating position fixed on the adjustment rail 30 to another and thus to adjust the length of the finger movement rail 2, a connecting element 20a or 20b (cf. Fig.6 ) a finger movement rail 2 arranged on a holding means 34 is moved by means of a drive 10, in particular by means of the spindle 102 driven by the motor 101 of the drive 10, via a carriage 33 along an adjustment rail 30 from an amplitude A1 for a therapeutic movement into a first A2 or second A3 adjustment range. When the carriage 33 is moved in a first direction B1 along the adjustment rail 30 into the first adjustment range A2 by means of the drive 10, in particular by means of the spindle 102 driven by the motor 101 of the drive 10, it exerts a force on the first blocking mechanism 31 upon contact with a first blocking mechanism 31, so that the first blocking mechanism 31 is released and the holding means 34 together with the finger movement rail 2 is moved by movement of the carriage 30 in the first direction B1. The blocking lever 312 is, as in Fig. 2 to be seen, moved away from the adjustment rail 30 or its grid elements 31 by a sliding foot 331 of the carriage 33 against the spring force of the means 313 for suspension, whereby the interaction between the blocking lever 312 and the adjustment rail 30 is cancelled and a movement of the carriage 33 together with the holding means 34 and the finger movement rail 2 is made possible. In the embodiment shown here, the carriage 33 can comprise two sliding feet 331 and a cross element 332 connecting the sliding feet 331 to one another, so that the carriage 33 can have an H-shaped configuration in particular in plan view. The blocking lever 322 of the second blocking mechanism 32 does not block the movement of the holding means 34 in the first direction B1, but can simply be pulled along by the holding means 34 moved by the carriage 33.

Fig. 3a zeigt die Längeneinstellvorrichtung 3 aus den Fig. 1 und 2 während der Bewegung in Richtung B1, wobei ein Blockierungshebel 322 des zweiten Blockierungsmechanismus 32 in einer maximal ausgelenkten Position oberhalb eines Rasterelements 301 ist. Fig. 3b zeigt dieselbe Längeneinstellvorrichtung 3 bei der sich der Blockierungshebel 322 des zweiten Blockierungsmechanismus 32 in einer minimal ausgelenkten Position befindet. Fig. 3a shows the length adjustment device 3 from the Fig. 1 and 2 during the movement in direction B1, wherein a blocking lever 322 of the second blocking mechanism 32 is in a maximally deflected position above a grid element 301. Fig. 3b shows the same length adjustment device 3 in which the blocking lever 322 of the second blocking mechanism 32 is in a minimally deflected position.

Entsprechend gilt für die Bewegung in eine entgegengesetzte zweite Richtung B2: Der Schlitten 30 einer erfindungsgemäßen Längeneinstellvorrichtung 3 ist so ausgelegt, dass, wenn er mittels des Antriebs 10, insbesondere mittels der durch den Motor 101 des Antriebs 10 angetriebenen Spindel 102; in die zweite Richtung B2 entlang der Einstellschiene 30 bewegt wird, bei Kontakt mit dem zweiten Blockierungsmechanismus 32 eine Kraft auf den zweiten Blockierungsmechanismus 32 ausübt, sodass der zweite Blockierungsmechanismus 32 gelöst und das Haltemittel 34 mitsamt der Finger-Bewegungsschiene 2 durch Bewegung des Schlittens 30 in die zweite Richtung B2 bewegbar ist. In diesem Fall übt der Schlitten 30, wenn er mittels des Antriebs 10 in eine zweite Richtung B2 entlang der Einstellschiene 30 in den zweiten Einstellbereich A3 bewegt wird, bei Kontakt mit einem zweiten Blockierungsmechanismus 32 eine Kraft auf den zweiten Blockierungsmechanismus 32 aus, sodass der zweite Blockierungsmechanismus 32 gelöst und das Haltemittel 34 mitsamt der Finger-Bewegungsschiene 2 durch Bewegung des Schlittens 33 in die zweite Richtung B2 bewegt wird. Die Kraftausübung kann auch hier wieder über den Gleitfuß 331 erfolgen. Der Blockierungshebel 312 des ersten Blockierungsmechanismus 31 blockiert die Bewegung des Haltemittels 34 in die zweite Richtung B2 nicht, sondern lässt sich einfach durch das vom Schlitten 33 bewegte Haltemittel 34 mitziehen.The following applies accordingly to the movement in an opposite second direction B2: The carriage 30 of a length adjustment device 3 according to the invention is designed such that when it is moved in the second direction B2 along the adjustment rail 30 by means of the drive 10, in particular by means of the spindle 102 driven by the motor 101 of the drive 10; upon contact with the second blocking mechanism 32, a force is exerted on the second blocking mechanism 32, so that the second blocking mechanism 32 is released and the holding means 34 together with the finger movement rail 2 can be moved in the second direction B2 by moving the carriage 30. In this case, when the carriage 30 is moved by the drive 10 in a second direction B2 along the adjustment rail 30 into the second adjustment range A3, it exerts a force on the second blocking mechanism 32 upon contact with a second blocking mechanism 32, so that the second blocking mechanism 32 is released and the holding means 34 together with the finger movement rail 2 is moved in the second direction B2 by moving the carriage 33. The force can also be applied here via the sliding foot 331. The blocking lever 312 of the first blocking mechanism 31 blocks the movement of the holding means 34 in the second direction B2. but can simply be pulled along by the holding means 34 moved by the carriage 33.

Die Einstellschiene 30 kann insbesondere eine Rasterbahn mit wenigstens zwei Rasterelementen 301 sein. Dabei können die wenigstens zwei Rasterelemente 301 als im Wesentlichen keilförmig (dreieckig) - wie insbesondere in den Fig. 1 bis 3b gezeigt - und/oder halbkreisförmig und/oder in Form eines Kreisbogendreiecks (sog. "Reuleaux-Dreieck") aus der Ebene der Einstellschiene 30 herausragen. In den Fig. 2, 3a und 3b ist zu sehen, wie die Blockierungshebel 31 und 32 mit derartig aus der Ebene der Einstellschiene 30 herausragenden Rasterelementen 301 wechselwirken können, so dass jeweils ein Blockierungshebel 31 oder 32 in eine Bewegungsrichtung B1 oder B2 die Bewegung des Haltemittels 34 blockiert und in die jeweils andere Bewegungsrichtung über die Rasterelemente 301 hinweggezogen werden kann.The adjustment rail 30 can in particular be a grid track with at least two grid elements 301. The at least two grid elements 301 can be designed as essentially wedge-shaped (triangular) - as in particular in the Fig. 1 to 3b shown - and/or semicircular and/or in the form of a circular arc triangle (so-called "Reuleaux triangle") protrude from the plane of the adjustment rail 30. In the Fig. 2 , 3a and 3b it can be seen how the blocking levers 31 and 32 can interact with grid elements 301 protruding from the plane of the adjustment rail 30 in such a way that a blocking lever 31 or 32 blocks the movement of the holding means 34 in a direction of movement B1 or B2 and can be pulled over the grid elements 301 in the other direction of movement.

Die Blockierungsmechanismen 31 und 32 umfassen dazu vorzugsweise jeweils wenigstens: ein am Haltemittel 34, vorzugsweise an der ersten Seitenwand 341, angeordnetes Fixiermittel 314 bzw. 324; einen, über eine Drehachse 311 bzw. 321 drehbar am Haltemittel 34, vorzugsweise an der ersten Seitenwand 341, angelenkten Blockierungshebel 312 bzw. 322; und ein Mittel zur Federung 313 bzw. 323 des Blockierungshebels 312 bzw. 322 gegenüber dem Fixiermittel 314 bzw. 324; wobei der Blockierungshebel 312 bzw. 322 so ausgelegt ist, dass, wenn der Schlitten 33 mit dem Blockierungshebel 313 bzw. 323 in Wirkverbindung tritt, der Blockierungshebel 312 bzw. 323 von einer Blockierungsposition P1 in eine Deblockierungsposition P2 gedreht wird und das Haltemittel 34 dadurch in wenigstens eine Richtung B1 bzw. B2 bewegbar ist. Dabei können die Blockierungshebel 313 bzw. 323 in ihrer jeweiligen Blockierungsposition P1 mit der Einstellschiene 30, insbesondere mit den Rasterelementen 301 einer als Rasterbahn ausgebildeten Einstellschiene 30, vorzugsweise in Wirkverbindung sein und in ihrer jeweiligen Deblockierungsposition P2 mit der mit der Einstellschiene 30, insbesondere mit den Rasterelementen 301 einer als Rasterbahn ausgebildeten Einstellschiene 30, vorzugsweise nicht in Wirkverbindung sein.For this purpose, the blocking mechanisms 31 and 32 preferably each comprise at least: a fixing means 314 or 324 arranged on the holding means 34, preferably on the first side wall 341; a blocking lever 312 or 322 pivoted on the holding means 34, preferably on the first side wall 341, via a rotation axis 311 or 321; and a means for springing 313 or 323 the blocking lever 312 or 322 relative to the fixing means 314 or 324; wherein the blocking lever 312 or 322 is designed such that when the carriage 33 comes into operative connection with the blocking lever 313 or 323, the blocking lever 312 or 323 is rotated from a blocking position P1 into a deblocking position P2 and the holding means 34 is thereby movable in at least one direction B1 or B2. In this case, the blocking levers 313 or 323 can preferably be in operative connection with the adjustment rail 30, in particular with the grid elements 301 of an adjustment rail 30 designed as a grid track, in their respective blocking position P1 and preferably not be in operative connection with the adjustment rail 30, in particular with the grid elements 301 of an adjustment rail 30 designed as a grid track, in their respective deblocking position P2.

Alternativ zu einer mehrteiligen Ausgestaltung der Blockierungsmechanismen 31 bzw. 32 wie beschrieben, können die Blockierungsmechansimen 31 bzw. 32 auch vorteilhaft einteilig ausgebildet und aus federndem Material, insbesondere aus Federstahl und/oder Hartgummi, gebildet sein.As an alternative to a multi-part design of the blocking mechanisms 31 and 32 as described, the blocking mechanisms 31 and 32 can also advantageously be designed in one piece. and be made of resilient material, in particular spring steel and/or hard rubber.

Die Fig. 4a und Fig. 4b zeigen einen schematischen Vergleich einer ersten, mehrteiligen Ausgestaltung eines erfindungsgemäßen Blockierungsmechanismus 31 bzw. 32 (Fig. 4a) und einer zweiten, einteilig aus einem federnden Material gebildeten Ausgestaltung eines erfindungsgemäßen Blockierungsmechanismus 31 bzw. 32 (Fig. 4b). Es ist zu sehen, dass in dieser Ausgestaltung die Fixiermittel 314 bzw. 324 und die Blockierungshebel 313 bzw. 323 vorteilhaft aus einem einzigen Stück federndem Material, beispielsweise aus Federstahl und/oder aus Hartgummi, gebildet werden können, wobei die Blockierungshebel 313 bzw. 323 gegenüber den Fixiermittel 314 bzw. 324 vorzugsweise abgewinkelt angeordnet und die Schnittpunkte zwischen den Blockierungshebeln 313 bzw. 323 und den Fixiermitteln 314 bzw. 324 den Drehachsen 311 bzw. 321 entsprechen.The Fig. 4a and Fig. 4b show a schematic comparison of a first, multi-part embodiment of a blocking mechanism 31 or 32 according to the invention ( Fig. 4a ) and a second embodiment of a blocking mechanism 31 or 32 according to the invention, formed in one piece from a resilient material ( Fig. 4b ). It can be seen that in this embodiment the fixing means 314 and 324 and the blocking levers 313 and 323 can advantageously be formed from a single piece of resilient material, for example from spring steel and/or hard rubber, wherein the blocking levers 313 and 323 are preferably arranged at an angle to the fixing means 314 and 324 and the intersection points between the blocking levers 313 and 323 and the fixing means 314 and 324 correspond to the axes of rotation 311 and 321.

Alternativ zu einer als Rasterbahn mit wenigstens zwei, aus der Ebene der Einstellschiene 30 herausragenden, Rasterelementen 301 ausgebildeten Einstellschiene 30, können die wenigstens zwei Rasterelemente 301 der als Rasterbahn ausgebildeten Einstellschiene 30 auch als Löcher innerhalb der Einstellschiene 30 ausgestaltet sein (nicht gezeigt).As an alternative to an adjustment rail 30 designed as a grid track with at least two grid elements 301 protruding from the plane of the adjustment rail 30, the at least two grid elements 301 of the adjustment rail 30 designed as a grid track can also be designed as holes within the adjustment rail 30 (not shown).

Fig. 5 zeigt eine zweite Ausgestaltung einer erfindungsgemäßen Längeneinstellvorrichtung 3 mit einer Finger-Bewegungsschiene 2 bei der die Einstellschiene 30 entlang ihrer Längsachse vorzugsweise eine erste Seitenwand 302 und eine zweite Seitenwand 303 umfasst, wobei die erste Seitenwand 302, die Einstellschiene 30 und die zweite Seitenwand 303 zusammen ein im Wesentlichen U-förmigen Querschnitt bilden, und wobei insbesondere das Haltemittel 34 innerhalb des im Wesentlichen U-förmigen Querschnitts bezüglich der Einstellschiene 30 bewegbar angeordnet ist. Zur Realisierung dieser vergleichsweise kompakt gebauten Ausgestaltung ist der Schlitten 33 hier vorzugsweise mittelbar über wenigstens ein Verbindungselement 103 mit dem Antrieb 10 wirkverbunden (vgl. auch Fig. 6). Fig.5 shows a second embodiment of a length adjustment device 3 according to the invention with a finger movement rail 2, in which the adjustment rail 30 preferably comprises a first side wall 302 and a second side wall 303 along its longitudinal axis, wherein the first side wall 302, the adjustment rail 30 and the second side wall 303 together form a substantially U-shaped cross section, and wherein in particular the holding means 34 is arranged to be movable within the substantially U-shaped cross section with respect to the adjustment rail 30. To realize this comparatively compact design, the carriage 33 is preferably indirectly operatively connected to the drive 10 via at least one connecting element 103 (see also Fig.6 ).

In Fig. 6 ist schließlich eine Seitenansicht einer Ausgestaltung einer FingerBewegungsschiene 2 mit Längeneinstellvorrichtung 3 und Antrieb 10 gezeigt. Der Antrieb 10 kann vorzugsweise ein linearer Antrieb, insbesondere ein Spindelmotor, ein Pneumatikzylinder, ein Hydraulikzylinder und/oder ein Seilzug, sein. Fig. 6 zeigt exemplarisch einen als Spindelmotor ausgebildeten Antrieb 10, dessen Motor 101 eine Spindel 102 antreibt, welche wiederum über wenigstens ein Verbindungselement 103 mit dem Schlitten 33 wechselwirkt. Das Verbindungselement 103 kann dazu vorzugsweise wenigstens einen Abschnitt umfassen, der innerhalb des von Einstellschiene 30, erster Seitenwand 302 und zweiter Seitenwand 303 gebildeten, im Wesentlichen U-förmigen Querschnitts verläuft (vgl. dazu auch Fig. 5).In Fig.6 Finally, a side view of an embodiment of a finger movement rail 2 with length adjustment device 3 and drive 10 is shown. The drive 10 can preferably be a linear drive, in particular a spindle motor, a pneumatic cylinder, a hydraulic cylinder and/or a cable pull. Fig.6 shows exemplary a drive 10 designed as a spindle motor, the motor 101 of which drives a spindle 102, which in turn interacts with the carriage 33 via at least one connecting element 103. The connecting element 103 can preferably comprise at least one section that runs within the essentially U-shaped cross section formed by the adjustment rail 30, the first side wall 302 and the second side wall 303 (see also Fig.5 ).

Die erfindungsgemäße Längeneinstellvorrichtung 3 bzw. das erfindungsgemäße Verfahren zur Längeneinstellung ermöglicht es vorteilhaft, eine Finger-Bewegungsschiene 2 mit Hilfe des für die Finger-Bewegungsschiene 2 auf einem Therapiegerät 1 bereits vorhandenen Antriebs 10 entlang der Einstellschiene 30 automatisch zu verschieben und an einer gewünschten Position - in Abhängigkeit der Fingerlänge bzw. Handgröße/länge des Benutzers - auf der Einstellschiene 30 und damit auf dem Therapiegerät 1 zu fixieren, um dann in einer stabilen Position eine kontinuierliche, passive und/oder aktiv-assistierte Bewegung eines Fingers und/oder eines Daumens einer Hand durchführen zu können. Ein zeitaufwendiges manuelles Einstellen ist dadurch vorteilhaft vermieden.The length adjustment device 3 according to the invention or the method for length adjustment according to the invention advantageously makes it possible to automatically move a finger movement rail 2 along the adjustment rail 30 using the drive 10 already present for the finger movement rail 2 on a therapy device 1 and to fix it in a desired position - depending on the finger length or hand size/length of the user - on the adjustment rail 30 and thus on the therapy device 1 in order to then be able to carry out a continuous, passive and/or actively assisted movement of a finger and/or a thumb of a hand in a stable position. Time-consuming manual adjustment is thus advantageously avoided.
