Abstract
Description
Die Erfindung betrifft ein Kniekissen zum Abstützen der Knie beim Arbeiten in kniender Körperhaltung.The invention relates to a knee cushion for supporting the knees when working in a kneeling posture.
Die zunehmende Zahl von Wirbelsäulenschäden beim Menschen fördert immer mehr die Erkenntnis, daß man Arbeiten mit bogenförmig gekrümmtem Rücken möglichst vermeiden soll. Deshalb bevorzugt man bei vielen Arbeiten eine kniende Körperhaltung, in der die Wirbelsäule weniger oder nicht gekrümmt werden muß. Das Knien auf harten und oftmals auch kalten Unterlagen ist jedoch ebenfalls problematisch und kann zu einer Druckschädigung des Knies, beispielsweise Meniskusschäden, Schleimbeutelentzündungen oder Nervenschädigungen, führen. Deshalb finden an den Knien zu tragende Knieschützer und auf den Boden zu legende Kniekissen zunehmend Verbreitung, insbesondere bei Gärtnern, Fliesenlegern oder Bergarbeitern.The increasing number of spinal injuries in humans increasingly promotes the realization that work with an arched back should be avoided as far as possible. For this reason, a kneeling posture is preferred in many jobs, in which the spine has to be bent less or not. Kneeling on hard and often cold pads is also problematic and can lead to pressure damage to the knee, such as meniscus damage, bursitis or nerve damage. That is why knee protectors to be worn on the knees and knee pillows to be placed on the floor are becoming increasingly popular, especially among gardeners, tilers or miners.
Kniekissen bieten gegenüber Knieschützern den Vorteil, daß sie nicht an den Knien befestigt werden müssen und daß man bei einem vorübergehenden Unterbrechen seiner knienden Arbeit nicht mit den Knieschützern herumlaufen muß. Sie stützen jedoch die Knie weniger gut als Knieschützer.Knee pads offer the advantage over knee pads that they do not have to be attached to the knees and that you do not have to walk around with the knee pads if you temporarily stop kneeling. However, they support the knees less well than knee pads.
Der Erfindung liegt das Problem zugrunde, ein Kniekissen der eingangs genannten Art so zu gestalten, daß eine möglichst optimale und körperschonende kniende Haltung eingenommen werden kann.The invention is based on the problem of designing a knee pillow of the type mentioned at the beginning in such a way that a kneeling posture which is as optimal as possible and gentle on the body can be adopted.
Dieses Problem wird erfindungsgemäß dadurch gelöst, daß in einer Schaumstoffplatte parallel zueinander zwei entsprechend der beiden menschlichen Knie für das rechte und linke Knie unterschiedliche, in die Schaumstoffplatte hineinführende Ausformungen vorgesehen sind.This problem is solved according to the invention in that in a foam sheet parallel to each other two corresponding to the two human knees for the right and left knees are provided, leading into the foam sheet.
Durch solche, für das rechte und linke Knie unterschiedliche Ausformungen, welche genau wie die Füße spiegelsymmetrisch zueinander verlaufen, ergibt sich eine optimale Abstützung der Knie. Deshalb hat eine auf dem erfindungsgemäßen Kniekissen kniende Person einen noch besseren Halt als bei Benutzung von Knieschützern, und unzulässig hohe Druckbeanspruchungen der Knie werden vermieden. Das erfindungsgemäße Kniekissen ist insbesondere bei solchen Arbeiten gegenüber Knieschützern mit Vorteil zu verwenden, bei denen man über längere Zeit an ein und derselben Stelle verbleiben kann.Such different configurations for the right and left knees, which, like the feet, are mirror-symmetrical to one another, result in optimal support of the knees. Therefore, a person kneeling on the knee pillow according to the invention has an even better grip than when using knee protectors, and inadmissibly high pressure loads on the knees are avoided. The knee pillow according to the invention can be used with advantage particularly in such work over knee protectors in which one can remain in one and the same place for a long time.
Besonders vorteilhaft ist es, wenn gemäß einer Weiterbildung der Erfindung sich den Ausformungen jeweils eine schalenförmige, beim Knien in dem Kniekissen gegen das jeweilige Schienbein gelangende Abstützfläche anschließt. Durch eine solche Abstützfläche wird ein Teil des Körpergewichtes statt über die Knie über beide Schienbeine abgestützt, so daß es zu einer Entlastung der Knie kommt. Weiterhin werden hierdurch die Füße beim Knien weniger beansprucht, weil das jeweilige Schienbein beim Knien eine erhöhte Position einnimmt. Man könnte sogar die Ausformungen so tief ausbilden, daß eine ausschließliche Abstützung über die Schienbeine erfolgt.It is particularly advantageous if, according to a further development of the invention, each of the formations is followed by a shell-shaped support surface which, when kneeling in the knee cushion, reaches the respective shin. Such a support surface supports part of the body weight over both shins instead of over the knees, so that the knees are relieved. Furthermore, the feet are less stressed when kneeling because the respective shin occupies an elevated position when kneeling. You could even form the formations so deep that there is an exclusive support via the shins.
Das Kniekissen hat optimale Polstereigenschaften bei ausreichend hoher Formstabilität und ist besonders kostengünstig herzustellen, wenn es aus Polyurethanschaum besteht.The knee cushion has optimal cushioning properties with sufficiently high dimensional stability and is particularly inexpensive to manufacture if it consists of polyurethane foam.
Eine andere, vorteilhafte Weiterbildung des erfindungsgemäßen Kniekissens besteht darin, daß seine Bodenfläche an der einem in dem Kniekissen Knienden abgewandten, vorderen Seite eine nach oben gerichtete Ausnehmung zum Untergreifen des Kniekissens bei auf einer Fläche liegendem Kniekissen aufweist. Hierdurch kann man das Kniekissen besonders gut untergreifen und beispielsweise einen geringen Betrag nach vorn schieben, wenn man sein kniende Position verändern will.Another advantageous development of the knee pillow according to the invention is that its bottom surface on the front side facing away from one of the knee pillow ends has an upward recess for reaching under the knee pillow when the knee pillow lies on a surface. This allows you to grip the knee cushion particularly well and, for example, push a small amount forward if you want to change your kneeling position.
Besonders gut und ohne unerwünscht hohe Haltekräfte läßt sich das Kniekissen greifen, wenn zusätzlich zu der Ausnehmung in seiner Oberseite im Bereich der Ausnehmung eine Griffmulde eingeformt ist.The knee cushion can be gripped particularly well and without undesirably high holding forces if, in addition to the recess in its upper side, a recessed grip is formed in the region of the recess.
Beim Arbeiten lassen sich kleinere Gegenstände auf dem Kniekissen ablegen, wenn gemäß einer anderen Weiterbildung der Erfindung zwischen den Ausformungen in der Oberseite für die Knie eine Ablagemulde vorgesehen ist.When working, smaller objects can be placed on the knee cushion if, according to another development of the invention, a storage trough is provided for the knees between the shapes in the top.

Wie die Figur 1 erkennen läßt, ist das Kniekissen aus einer rechteckigen Schaumstoffplatte 1 gebildet. Diese besteht aus Polyurethan. In diese Schaumstoffplatte 1 führen von ihrer Oberseite her symmetrisch zu einer Mittellinie 2 zwei Ausformungen 3, 4 hinein, welche genau entsprechend der menschlichen Knie geformt sind, wobei in die in Figur 1 gesehen obere Ausformung 3 ein rechtes Knie und in die Ausformung 4 ein linkes Knie paßt. Genau wie bei Schuhen kann das Kniekissen mit unterschiedlichen Weiten gefertigt werden.As can be seen in FIG. 1, the knee pillow is formed from a
Die Ausformungen 3, 4 gehen in schalenförmige Abstützflächen 5, 6 über, welche bis in die einem Benutzer zugewandte Seitenfläche der Schaumstoffplatte 1 verlaufen. Beim Knien stützt sich das jeweilige Schienbein zusätzlich zum Knie in der Ausformung 3 oder 4 auf diesen Abstützflächen 5 oder 6 ab.The
Die Figur 2 läßt erkennen, daß die Schaumstoffplatte 1 in ihrer Bodenfläche 7 im Bereich ihrer vorderen Seite eine Ausnehmung 8 hat, welche so bemessen ist, daß man bei dem beispielsweise auf dem Boden liegenden Kniekissen in diese Ausnehmung 8 greifen kann, um das Kniekissen erfassen zu können. Oberhalb der Ausnehmung 8 befindet sich in der Oberseite der Schaumstoffplatte 1 eine Griffmulde 9, die das bequeme Ergreifen und Halten des Kniekissens weiter fördert.Figure 2 shows that the
Zwischen den Ausformungen 3, 4 ist in der Oberseite der Schaumstoffplatte 1 eine Ablagemulde 10 angeordnet, welche es erlaubt, bei Benutzung des Kniekissens kleinere Gegenstände auf dem Kniekissen abzulegen.Between the
