Abstract

Centrifugal brake for a pushchair or wheelchair comprises an extending brake piston (2) fixed in a brake hook with a weight (3) on a free-running rear axle (1) of the chair. The brake piston moves with the rear axle in a fixed housing (5) connected to an axle suspension (7). When a maximum speed is exceeded, the brake hook with a weight extends due to the centrifugal force to such an extent that it catches in the holder (6) for the brake hook. The brake is released by simple rotation against the previous direction of rotation and returned to its original position by a spring (4).

Description

Ziel der Erfindung ist es, einen Kinderwagen, bzw. einen Rollstuhl, der außer Kontrolle geraten ist, nach Überschreiten einer Maximalgeschwindigkeit automatisch abzubremsen. Der gegenwärtige Stand der Technik umfaßt Kinderwagen mit Feststellbremse, die mit dem Fuß aktiviert wird und einen sicheren Stand gewährleistet.The aim of the invention is one Strollers or a wheelchair that has gotten out of control after being exceeded brake automatically at a maximum speed. The current status of Technology includes Pushchair with parking brake that is activated with the foot and one secure standing guaranteed.

Außerdem gibt es Kinderwagen, deren Bremse durch nachlassenden Druck am Griff des Kinderwagens aktiviert wird. D.h. entgleitet der Kinderwagen z.B. in abschüssigem Gelände der schiebenden Person, stellt sich der Griff des Kinderwagens, durch Federkraft bewegt, in die abbremsende Position.There are also strollers their brakes by releasing pressure on the handle of the stroller is activated. That the stroller slips e.g. in sloping terrain pushing the handle of the stroller Spring force moves to the braking position.

Bei Rollstühlen kann die Person im Rollstuhl direkt manuell auf den Handlauf am Rad einwirken und somit abbremsen.With wheelchairs, the person in the wheelchair can directly Manually act on the handrail on the wheel and thus brake.

Daneben gibt es noch einige Bremsvarianten, die über Hebel, Züge und über Bremsbacken auf Reifen bzw. Rad einwirken.There are also a few braking options the above Levers, trains and over Apply the brake shoes to the tire or wheel.

Gerät jedoch ein Kinderwagen, der nur mit einer herkömmlichen Feststellbremse ausgestattet ist, bei abschüssigem Gelände außer Kontrolle, d.h. entgleitet der schiebenden Person, so besteht die Gefahr der Kollision des Kinderwagens mit einem feststehenden Hindernis, mit einem Fahrzeug, oder sogar eines Sturzes in einen Abgrund.However, a stroller that only with a conventional one Parking brake is equipped, on sloping terrain out of control, i.e. slips the pushing person, there is a risk of collision of the Stroller with a fixed obstacle, with a vehicle, or even falling into an abyss.

Auch bei Personen in Rollstühlen, die nicht selbständig in der Lage sind zu bremsen, besteht die oben genannte Gefahr.Even for people in wheelchairs who not independent are able to brake, there is the above risk.

Dieses Problem wird gelöst durch eine Fliehkraftbremse für Kinderwagen und Rollstühle. Die Fliehkraftbremse für Kinderwagen und Rollstühle besteht aus einem ausfahrbaren Bremskolben, der an der frei laufenden Hinterachse des Kinderwagens, bzw. Rollstuhls befestigt ist.This problem is solved by a centrifugal brake for Strollers and wheelchairs. The centrifugal brake for Strollers and wheelchairs consists of an extendable brake piston that is attached to the free-running Rear axle of the stroller or wheelchair is attached.

Während der Fahrt im normalen Geschwindigkeitsrahmen dreht sich der ausfahrbare Bremskolben einfach mit der frei laufenden Hinterachse, ohne deren Drehung zu beeinflussen.While the extendable turns when driving at normal speed Brake pistons simply with the free-running rear axle without it To influence rotation.

Überschreitet die Geschwindigkeit des Kinderwagens bzw. Rollstuhls einen Maximalwert, so wirkt die Fliehkraft der frei laufenden Achse auf den ausfahrbaren Bremskolben, der durch das Gewicht am Bremshaken auseinander gezogen wird.exceeds the speed of the stroller or wheelchair has a maximum value, this is how the centrifugal force of the free-running axle acts on the extendable axle Brake piston pulled apart by the weight on the brake hook becomes.

Ist eine kritische Geschwindigkeit erreicht, so verhakt sich der Bremshaken in der dafür vorgesehenen Halterung am fest stehenden Gehäuse, das mit der Achsenaufhängung verbunden ist, und die Hinterachse des Kinderwagens, bzw. Rollstuhls wird sofort abgestoppt. Kinderwagen, bzw. Rollstuhl werden auf dem kürzesten Weg zu Halten gebracht und die Gefährdung der Insassen auf ein Mindestmaß reduziert. Der Bremshaken und die Halterung sind für Drehungen vorwärts und rückwärts ausgelegt.Is a critical speed reached, the brake hook snags in the designated one Bracket on the fixed housing, the one with the axle suspension is connected, and the rear axle of the stroller or wheelchair is stopped immediately. Strollers or wheelchairs are on the shortest Brought away to keep the occupants at risk Minimum size reduced. The brake hook and bracket are for forward and twists laid out backwards.

Die Feststellung der Fliehkraftbremse kann durch eine einfache Drehung der Achse entgegen der vorherigen Drehrichtung wieder gelöst werden. Ein Federzug im Innern des Bremskolbens bringt diesen wieder in seine Ausgangsposition zurück.The determination of the centrifugal brake can be done by simply rotating the axis counter to the previous one Direction of rotation released again become. A spring balance inside the brake piston brings it back back to its starting position.
