Description

Die Erfindung betrifft einen Gehwagen, auch Rollator genannt, mit schwenkbarem Vorderrahmen, als Gehhilfe für ältere oder gehbehinderte Menschen.The The invention relates to a walker, also called Rollator, with swiveling Front frame, as a walker for older or handicapped people.

Nach dem Stand der Technik (1) lässt sich ein Gehwagen zum vereinfachten Transport zwar zusammenklappen, aus Gründen der Kipp- und Standsicherheit ist dessen Rahmen bei Gebrauch jedoch auseinander zu klappen und festzustellen. Der Gehwagen nach dem Stand der Technik lässt sich bei angezogener Handbremse (1), die auf die Hinterräder wirkt, zwar um die Achse (8) der Hinterräder (7) drehen (2), so dass die Vorderräder (6) vom Untergrund abheben, wenn er entgegen der vorwärts gerichteten Laufrichtung an den Haltegriffen (2) zurückgezogen wird, jedoch lässt sich ein Hindernis (5) nicht überwinden, da eine Vorwärtsbewegung in Laufrichtung bei angezogener Hinterradbremse (1) ausgeschlossen ist. Wird die Bremse gelöst, rollt der Gehwagen gegen die Laufrichtung zurück, bis alle Räder das ursprüngliche Niveau erreicht haben. Will man mit dem Gehwagen nach dem Stand der Technik ein Hindernis wie z.B. eine Bordsteinkante überwinden, ist er anzuheben und über das Hindernis zu tragen.According to the state of the art ( 1 ), a walker for simplified transport indeed collapse, but for reasons of tipping and stability whose frame is in use to unfold and determine apart. The walker according to the prior art can be with the handbrake ( 1 ), which acts on the rear wheels, although about the axis ( 8th ) of the rear wheels ( 7 ) rotate ( 2 ), so the front wheels ( 6 ) from the ground when it is against the forward direction of travel on the handles ( 2 ) is withdrawn, but an obstacle ( 5 ), since a forward movement in the running direction when the rear brake is applied ( 1 ) is excluded. When the brake is released, the walker rolls back against the running direction until all wheels have reached their original level. If you want to overcome an obstacle such as a curb with the walker according to the prior art, it is to lift and carry over the obstacle.

Erstrebt ist ein Gehwagen, der bei entsprechender Kipp- und Standsicherheit das Überwinden von Hindernissen, wie zum Beispiel Bordsteinkanten, erleichtert und unterstützt.sought is a walker, with the appropriate tilt and stability overcoming Obstacles, such as curbs, and facilitates supported.

Die Erfindung zur Lösung dieser Aufgabe nach Anspruch 1 betrifft einen Gehwagen mit schwenkbarem Vorderrahmen (3-5). Wird der Gehwagen mit seinen Vorderrädern (6) gegen ein Hindernis (5), zum Beispiel eine Bordsteinkante, geführt, blockieren die Vorderräder (6) und der Vorderrahmen (3) schwenkt im Drehpunkt (9) gegen die Laufrichtung auf den Hinterrahmen (4) ein und staucht dabei ein oder mehrere Federelemente (10), zum Beispiel Gasdruckstoßdämpfer oder hydraulische Stoßdämpfer (4). Die hierin gespeicherte Energie in Form einer gestauchten Feder oder verdichteten Gases wirkt dem Einschwenken entgegen und drückt den Vorderrahmen (3) in Laufrichtung zurück (5), wenn der Gehwagen am Haltegriff (2) nach hinten gezogen die Vorderräder (6) nach vorne frei gibt.The invention for solving this problem according to claim 1 relates to a walker with pivoting front frame ( 3 - 5 ). Will the walker with its front wheels ( 6 ) against an obstacle ( 5 ), for example, a curb, led, block the front wheels ( 6 ) and the front frame ( 3 ) pivots in the pivot point ( 9 ) against the running direction on the rear frame ( 4 ) and upsetting one or more spring elements ( 10 ), for example gas pressure shock absorbers or hydraulic shock absorbers ( 4 ). The energy stored therein in the form of a compressed spring or compressed gas counteracts the swiveling in and presses the front frame (FIG. 3 ) in the running direction back ( 5 ), when the walker on the handle ( 2 ) pulled back the front wheels ( 6 ) releases to the front.

Nach der Erfindung schwenkt der Vorderrahmen (3) in Laufrichtung aus. Die Handbremse (1) blockiert währenddessen die Hinterräder (7). Der Gehwagen wird um die Achse der Hinterräder (8) gedreht, die Vorderräder (6) aufgestellt, die Bremse (1) gelöst und die Hinterräder (7) an das Hindernis (5) herangerollt und auf die Ebene der Vorderräder (6) gehebelt.After the invention, the front frame pivots ( 3 ) in the running direction. The handbrake ( 1 ) blocks the rear wheels ( 7 ). The walker is about the axis of the rear wheels ( 8th ), the front wheels ( 6 ), the brake ( 1 ) and the rear wheels ( 7 ) to the obstacle ( 5 ) and to the level of the front wheels ( 6 ) leveraged.

Dabei löst sich die Erfindung sowohl von der Frage, durch welche technische Einrichtung beim Einschwenken des Vorderrahmens Energie aufgenommen und gespeichert wird, um das anschließende Ausschwenken des Vorderrahmens in Laufrichtung zu bewirken, als auch deren Anordnung sowie die Anordnung des Drehpunktes des Vorderrahmens.there dissolves the invention of both the question by which technical device Energy absorbed and stored when swinging in the front frame will be to the subsequent Swinging the front frame in the direction of effect, as also their arrangement and the arrangement of the pivot point of the front frame.

In den 3-5 ist ein Ausführungsbeispiel der Erfindung dargestellt.In the 3 - 5 an embodiment of the invention is shown.

Der Vorderrahmen (3) ist um eine Achse im Drehpunkt (9) beweglich angeordnet. Der Gehwagen (3) wird gegen ein Hindernis (5) geschoben, wobei der Vorderrahmen (3) um den Drehpunkt (9) gegen die Laufrichtung auf den Hinterrahmen (4) einschwenkt (4) und hierbei auf das Federelement (10) wirkt. Über die Hinterradbremse (1) wird der Gehwagen festgestellt und anschließend an den Griffen (2) nach hinten gezogen. Dadurch dreht sich der Gehwagen um die Achse der Hinterräder (8), die Vorderräder (6) heben sich vom Boden ab (5). Nach Überwindung des Hindernisses (5) schwenkt der Vorderrahmen (3) mit Hilfe der im Stoßdämpfer (10) gespeicherten Energie in Laufrichtung aus. Die Vorderräder (6) werden auf Höhe des zu überwindenden Hindernisses (5) abgestellt. Danach wird die Bremse (1) gelöst, die Hinterräder (7) an das Hindernis (5) herangerollt und auf die Höhe der Vorderräder (6) gehebelt.The front frame ( 3 ) is about an axis in the fulcrum ( 9 ) arranged movably. The walker ( 3 ) is against an obstacle ( 5 ), whereby the front frame ( 3 ) around the fulcrum ( 9 ) against the running direction on the rear frame ( 4 ) ( 4 ) and here on the spring element ( 10 ) acts. About the rear brake ( 1 ), the walker is detected and then attached to the handles ( 2 ) pulled backwards. As a result, the walker rotates about the axis of the rear wheels ( 8th ), the front wheels ( 6 ) lift off the ground ( 5 ). After overcoming the obstacle ( 5 ) the front frame ( 3 ) with the help of the shock absorber ( 10 ) stored energy in the direction of. The front wheels ( 6 ) at the height of the obstacle to be overcome ( 5 ) switched off. Then the brake ( 1 ), the rear wheels ( 7 ) to the obstacle ( 5 ) and to the height of the front wheels ( 6 ) leveraged.
