Abstract

Rollatorhilfsrad zum Überwinden von Hindernissen, dadurch gekennzeichnet, dass neben den Vorderrädern des Rollators ein weiteres, frei bewegliches Zusatzrad montiert wird, welches einen etwas geringeren Duchmesser aufweist als das Hauptrad. Am Hilfsrad befinden sich 4 kleinere Planetenräder, welche den Durchmesser des Hauptrades um 10–20% überragen. Das Hilfsrad ist auf der Hauptachse frei beweglich, die Planetenräder drehen ebenfalls frei. Der Patentanspruch bezieht sich auf das Hilfsrad mit den 4 Planetenrädern.Rollatorhilfsrad to overcome obstacles, characterized in that in addition to the front wheels of the rollator another, freely movable auxiliary wheel is mounted, which has a slightly smaller Diameter than the main wheel. The auxiliary wheel has 4 smaller planet wheels, which exceed the diameter of the main wheel by 10-20%. The auxiliary wheel is freely movable on the main axis, the planet wheels also rotate freely. The claim relates to the auxiliary wheel with the 4 planetary gears.

Description

Handelsübliche Rollatoren weisen an den Vorderrädern einen Raddurchmesser von ca. 15–25 cm auf.Commercially available rollators have a wheel diameter of about 15-25 cm on the front wheels.

Sie sind dadurch gekennzeichnet, dass jeweils rechts und links am Rollator sich ein Rad befindet, welches zentral und vertikal so montiert ist, dass die Räder um 360° bewegt werden können.They are characterized in that each right and left of the rollator is a wheel which is mounted centrally and vertically so that the wheels can be moved through 360 °.

Bei einer Hindernisshöhe von einigen Zentimetern wird jedoch das Überwinden dieses Hindernisses (insbesondere Bordsteinkanten aber auch flache Treppen) mit dieser Konstruktion zum Problem.With an obstacle height of a few centimeters, however, overcoming this obstacle (in particular curbs but also flat stairs) becomes a problem with this design.

Das Hilfsrad ist frei beweglich neben dem Hauptrad aufgehängt.The auxiliary wheel is suspended freely suspended next to the main wheel.

Bei normaler Fahrweise im Ebenen bleibt es in Waage, also ruhig.In normal driving in the levels, it remains in balance, so quiet.

In dem Moment einer Berührung mit einem Hindernis, insbesondere Bordsteinkante, greifen die Plantentenräder ähnlich einem Hebel auf das Hindernis zu und ”heben” die Haupträder praktisch über das Hindernis.At the moment of contact with an obstacle, in particular the curb, the planetary wheels grip the obstacle like a lever and "lift" the main wheels practically over the obstacle.

Sobald das Hindernis überwunden ist, befindet sich das Hilfsrad wieder in Ruhe.Once the obstacle is overcome, the auxiliary wheel is again at rest.

Mit dieser Konstruktion wird erreicht, dass insbesondere Sturz und Kantengefahr bei Rollatoren, möglicherweise aber auch in anderen Anwendungsbereichen (Sackkarren oder andere zum Transport von Güter geeigenten Räder) weitgehend ausgeschlossen wird.With this construction it is achieved that, in particular, camber and edge danger in rollators, but possibly also in other fields of application (sack trucks or other wheels suitable for the transport of goods), are largely ruled out.

Insbesondere erleichtert die Konstruktion gehbehinderten Menschen das gefahrlosere und leichtere Überwinden von alltäglichen Hindernissen wie Bordsteinkanten und möglicherweise nicht all zu hohen Treppen.In particular, the construction of handicapped people facilitates the safer and easier overcoming of everyday obstacles such as curbs and possibly not all too high stairs.

Der Vorteil dieser Erfindung besteht in der stark verminderten Unfallgefahr beim Einsatz von Rollatoren im Alltag.The advantage of this invention is the greatly reduced risk of accidents when using walkers in everyday life.

Eine Zeichnung wird entsprechend nachgereicht.A drawing will be submitted accordingly.
