Abstract

A walking aid comprising a shaft and a handle that, as viewed in a position of use of the walking aid, is disposed at an upper end of the shaft, the handle extending transverse to the shaft. The handle is inclined upwardly at an angle to the axis of the shaft. The handle is curved inwardly out of a plane formed by the handle and the shaft and toward the body of a user of the walking aid. When configured for right hand use, the handle is twisted clockwise, and when configured for left hand use, the handle is twisted in a counterclockwise direction.

Description

Die Erfindung betrifft eine Gehhilfe für Personen, deren Bewegungsfähigkeit durch Alter oder Erkrankung, z. B. nach Operation von Hüft- und Kniegelenken, eingeschränkt ist. In der Regel sind bei derart behinderten Personen, z. B. durch Muskelschwächung, auch die Kräfte beeinträchtigt, die für die Gehbewegung und zur Stützung des Körpergewichts aufgewendet werden müssen. Von entscheidender Bedeutung ist daher die Gestaltung der Gehhilfe dahingehend, dass die umzusetzenden Kräfte beim Gehen auch über einen längeren Zeitraum mit einem Mindestmaß an Ermüdung und möglichst schmerzfrei zur Wirkung kommen. Diese Forderungen werden von den meisten Gehhilfen nicht oder nur mangelhaft erfüllt. Die bekannten Griffformen entsprechen den Fertigungsmöglichkeiten, wobei der Griff in der Regel so ausgerichtet ist, dass seine Längsachse mit der Achse des Stockes in einer Ebene verläuft.The invention relates to a walker for persons whose mobility by age or disease, for. B. after surgery of hip and knee joints, is limited. As a rule, in such disabled persons, z. B. muscle weakening, also affects the forces that must be expended for walking and to support the body weight. Of crucial importance is therefore the design of the walker to the effect that the forces to be converted when walking over a longer period with a minimum of fatigue and painless as possible come to effect. These requirements are not or only poorly met by most walking aids. The known handle shapes correspond to the manufacturing possibilities, wherein the handle is usually aligned so that its longitudinal axis extends with the axis of the stick in a plane.

Mit einer gewölbten, etwa S-förmigen Gestaltung des Griffs kommt man zwar der Anatomie der Hand entgegen, jedoch wird eine anatomische Gestaltung der Individualität des Menschen nicht gerecht. Diese Art der Griffgestaltung ist sicherlich jeweils für einen Menschen optimal, aber für andere eben nicht. Der auf die Hand- und Armmuskulatur ausgeübte Druck ist dann nicht optimal, so dass insbesondere der auf der Hand- und Daumenwurzel lastende Druck zu Schmerzen und rascher Ermüdung führen kann.Although the anatomy of the hand is met by a curved, somewhat S-shaped design of the handle, an anatomical design does not do justice to the individuality of the individual. This type of grip design is certainly optimal for one person, but not for others. The pressure exerted on the hand and arm muscles is then not optimal, so that especially the pressure on the hand and thumb root pressure can lead to pain and rapid fatigue.

Dies gilt auch für eine andere bekannte Griffgestaltung ( DE 690 097 51 T2 ), bei der der Griff unter einem Winkel von wenigstens 15° zur Achse des Schaftes geneigt und der Anatomie der Hand angepasst ist.This also applies to another known grip design ( DE 690 097 51 T2 ), in which the handle is inclined at an angle of at least 15 ° to the axis of the shaft and adapted to the anatomy of the hand.

Es müsste bei einer anatomischen Griffgestaltung für jeden Betroffenen ein individueller Griff gefunden werden, was natürlich aus Kostengründen nicht möglich ist.It would have to be found with an anatomical handle design for each person affected an individual handle, which of course for cost reasons is not possible.

Die EP 0 931 474 *A1 beschreibt eine Gehhilfe mit einem Schaft und einem am oberen Ende der Schafts angeordneten Griff, der von der Seite aus betrachtet etwa eine J-Form hat. Wenn diese Gehhilfe horizontal auf eine Bodenfläche aufgelegt wird, ragt ein im Griff ausgebildeter Bereich vom Boden aufwärts. Der so ausgebildete Griff bildet ein Drehgelenk, um den der Schaft nach oben schwenkt, wenn man auf den von Boden aufragenden Bereich des Griffes tritt. Auf diese Weise kann die Gehhilfe, ohne das sich der Benutzer bücken muss, aufgehoben werden, wenn sie unbeabsichtigt auf den Boden gefallen ist. Die Funktion als Drehgelenk kann der Griff dadurch erfüllen, dass er beginnend am Schaft zunächst in die eine Richtung gebogen ist, und in dem sich anschließenden Bereich bis zum freien Ende des Griffs in die entgegen gesetzte Richtung gebogen ist.The EP 0 931 474 * A1 describes a walker having a shaft and a handle disposed at the upper end of the shaft which is approximately J-shaped when viewed from the side. When this walker is placed horizontally on a floor surface, an area formed in the handle protrudes from the floor upwards. The thus formed handle forms a hinge about which the shaft pivots upward when it comes to the bottom of the handle area. In this way, the walker, without the user has to bend down, can be repealed if it accidentally fell to the ground. The function as a hinge, the handle can be achieved in that it is initially bent on the shaft in one direction, and is bent in the adjoining area to the free end of the handle in the opposite direction.

Der Erfindung liegt die Aufgabe zugrunde, eine Gehhilfe aufzuzeigen, die eine optimale Kraftverteilung zwischen Hand und Griff ermöglicht, ohne dass eine individuelle Griffgestaltung für jeden Benutzer erforderlich ist.The invention has for its object to provide a walker that allows optimal power distribution between the hand and the handle, without an individual grip design is required for each user.

Ausgehend von einer Gehhilfe, bestehend aus einem Schaft und einem am oberen Ende des Schafts etwa quer zu diesem angeordneten Griff, der in einem Winkel zur Achse des Schafts aufwärts geneigt ist, wird die gestellte Aufgabe gemäß der Erfindung dadurch gelöst, dass der Griff etwa beim Schaft beginnend, zum freien Ende hin leicht einwärts zum Körper des Gehilfeträgers gekrümmt ist und, dass der Griff der Gehhilfe für die rechte Hand im Uhrzeigersinn und der Griff der Gehhilfe für die linke Hand gegen den Uhrzeigersinn verwunden ist.Starting from a walker, consisting of a shaft and a handle disposed at the upper end of the shaft approximately transversely to this, which is inclined at an angle to the axis of the shaft, the object is achieved according to the invention in that the handle as in the Beginning of the shaft, towards the free end slightly inward to the body of the patient's support is curved and that the handle of the walker for the right Hand clockwise and the handle of the walker for the left hand is twisted counterclockwise.

Die Erfindung weicht von anatomischen Griffausführungen bewusst ab und stellt statt dessen auf eine ergonomische, biodynamische Gestaltung des Griffs ab, wobei die erfindungsgemäßen Merkmale die bestmögliche Form des Gegenlagers für die konkave Innenhandlinie bilden und der Griff die optimale Innenhand-Auflage darstellt und eine hervorragende Entlastung der Spannsehnen bietet. Die Sicherheit des Benutzers wird erhöht, da der Griff die gewünschte Eigenart der Stützfunktion bei gleichzeitiger Entlastung (Schonung) des Handgelenks, der Bänder und Sehnen des Unterarms erfüllt. Die erfindungsgemäße Gehhilfe stellt daher eine echte Hilfe auch für die Behebung von Unsicherheit beim Gehen dar.The invention deviates consciously from anatomical handle designs and instead relies on an ergonomic, biodynamic design of the handle, wherein the features of the invention form the best possible form of the counter bearing for the concave inner hand line and the handle represents the optimal palm rest edition and excellent relief of Spannsehnen offers. The safety of the user is increased because the handle fulfills the desired peculiarity of the support function while at the same time relieving (relieving) the wrist, ligaments and tendons of the forearm. The walking aid according to the invention therefore represents a real help for the correction of insecurity when walking.

In Ausgestaltung der Erfindung beträgt der Radius der Einwärtskrümmung des Griffs zwischen 300 und 320 mm, vorzugsweise 310 mm, was zu einer verspannungsfreien Lage der Daumenwurzel führt.In an embodiment of the invention, the radius of the inward curvature of the handle is between 300 and 320 mm, preferably 310 mm, resulting in a tension-free position of the thumb root.

In weiterer Ausgestaltung der Erfindung erstreckt sich die Verwindung über einen Winkelbereich des Griffs von etwa 35° bis etwa 85°.In a further embodiment of the invention, the twist extends over an angular range of the handle of about 35 ° to about 85 °.

Vorzugsweise beträgt der Winkel zwischen der Achse des Schafts und dem aufwärts geneigten Griff zwischen 100° und 120°, vorzugsweise 110°.Preferably, the angle between the axis of the shaft and the upwardly inclined handle is between 100 ° and 120 °, preferably 110 °.

Fig. 1 zeigt einen Griff 1 einer erfindungsgemäß ausgebildeten Gehhilfe, der am oberen Ende eines Schafts 2 angeordnet ist. Er kann - wie dargestellt - integraler Bestandteil des Schafts 2 sein, er kann aber auch als gesondertes Teil mit dem Schaft 2 verbunden sein. Die Seitenansicht in Fig. 1a zeigt, dass der Griff 1 zum Schaft 2 unter einem Winkel a nach oben geneigt ist, wobei der Winkel zwischen 100° und 120° betragen sollte. Als besonders vorteilhaft hat sich ein Winkel von 110° erwiesen. Fig. 1 shows a handle 1 of an inventively designed walking aid, which is arranged at the upper end of a shaft 2. It can - as shown - be an integral part of the shaft 2, but it can also be connected as a separate part with the shaft 2. The side view in Fig. 1a shows that the handle 1 is inclined to the shaft 2 at an angle a upwards, the angle should be between 100 ° and 120 °. An angle of 110 ° has proved particularly advantageous.

Wie insbesondere die Unteransicht 1d und die Draufsicht 1e zeigen, ist der Griff 1, etwa beim Schaft 2 beginnend, zum freien Ende hin leicht einwärts gekrümmt. Fig. 1 zeigt die Gehhilfe, die von der rechten Hand erfasst werden soll, so dass die Einwärtskrümmung zum Körper des Benutzers gerichtet ist. Der Krümmungsradius R beträgt zwischen 300 und 320 mm. Versuche haben gezeigt, dass ein Krümmungsradius von 310 mm vom Benutzer als besonders angenehm empfunden wird. Die Breite des Griffs 1 nimmt dabei vom Schaft 2 zum freien Ende hin leicht zu, im dargestellten Ausführungsbeispiel von etwa 30mm auf 38 mm. Das Gleiche gilt für die nicht dargestellte spiegelbildliche Ausführung der von der linken Hand zu erfassenden Gehhilfe. Die Ausladung A des Griffs 1 nach innen beträgt jeweils etwa 22 mm bei einer Gesamtlänge B des Griffs 1 von etwa 110 mm.As shown in particular the bottom view 1d and the top view 1e, the handle 1, starting approximately at the shaft 2, is slightly curved inwards towards the free end. Fig. 1 shows the walker to be grasped by the right hand so that the inward curvature is directed towards the user's body. The radius of curvature R is between 300 and 320 mm. Experiments have shown that a radius of curvature of 310 mm is perceived by the user to be particularly pleasant. The width of the handle 1 increases from the shaft 2 to the free end easily, in the illustrated embodiment of about 30mm to 38 mm. The same applies to the unrepresented mirror image of the walker to be detected by the left hand. The projection A of the handle 1 inwards is about 22 mm at a total length B of the handle 1 of about 110 mm.

Gemäß der Erfindung ist der Griff 1 außerdem verwunden. Bei dem in Fig. 2 dargestellten Ausführungsbeispiel für die rechte Hand des Benutzers im Uhrzeigersinn. Hier ist an Hand von sechs im Abstand voneinander angeordneten Querschnitten auch eine besonders vorteilhafte Form gezeigt, die etwa oval ist und einem Brotlaib ähnelt, wobei die abgeflachte Seite etwa als Auflage für die Finger dient, wie am besten bei dem Querschnitt C-C ersichtlich ist. Die Querschnittsform ist jedoch nicht auf das dargestellte Beispiel beschränkt, sondern sie kann auch rund, quadratisch mit abgerundeten Ecken, als auch etwa dreieckig mit abgerundeten Flanken und Ecken sein. Eine bauchige Gestaltung der abgeflachten Seite ist ebenfalls möglich. Die gleiche Verwindung ist bei dem von der linken Hand des Benutzers zu erfassenden Griff 1 entgegen dem Uhrzeigersinn vorgesehen. Vorteilhafterweise erfolgt die Verwindung über einen Winkelbereich von etwa 35° bis etwa 85°.According to the invention, the handle 1 is also twisted. At the in Fig. 2 illustrated embodiment for the right hand of the user in a clockwise direction. Here is shown on the basis of six spaced-apart cross-sections also a particularly advantageous form, which is approximately oval and resembles a loaf, the flattened side serves as a support for the fingers, as best seen in the cross section CC. The cross-sectional shape is not limited to the illustrated example, but it may also be round, square with rounded corners, as well as approximately triangular with rounded edges and corners be. A bulbous design of the flattened side is also possible. The same twist is provided in the handle 1 to be detected by the user's left hand counterclockwise. Advantageously, the twisting over an angular range of about 35 ° to about 85 °.

Die Ausbildung der Verwindung bei dem Ausführungsbeispiel zeigt am besten Fig. 3, in der das obere Ende des Schafts 2 mit dem Griff 1 der erfindungsgemäßen Gehhilfe in sieben isometrischen Ansichten aus verschiedenen Blickrichtungen dargestellt ist.The formation of the twist in the embodiment best shows Fig. 3 in which the upper end of the shaft 2 is shown with the handle 1 of the walker according to the invention in seven isometric views from different directions.
