Abstract
Description
Einsatzgebiet der Erfindung sind Lenkrollen an Wagen, die von Hand bewegt werden wie z.B. Einkaufswagen oder andere Transportwagen.Field of application of the invention are Swivel castors on wagons that are moved by hand, e.g. Shopping venture or other dolly.
Diese Wagen fahren mit vier Rollen über den Boden. Zwei der Rollen sind starr. Bei den starren Rollen ist Drehachse des Rades starr mit dem Wagen verbunden. Zwei Rollen sind als Lenkrollen ausgebildet. Diese Rollen verfügen über eine zusätzliche Drehachse als Lenkachse senkrecht zur Drehachse des Rades. Bei Kurvenfahrt des Wagens kann die Lenkrolle eine Schwenkbewegung ausführen, indem sich die Rolle um die senkrechtstehende Achse dreht. Die Drehachse des Rades und die Lenkachse sind versetzt zueinander, so dass beim Fahren die Drehachse zu der Lenkachse nachläuft. Kurvenfahrt und einfache Manövrierbarkeit wird so ermöglicht. Wird die Bewegungsrichtung des Wagens um 180° geändert, so schwenkt die Rolle um 180° und die Lenkachsen der Rollen führen bei dieser Schwenkbewegung eine Seitwärtsbewegung aus. Die Größe der Seitwärtsbewegung entspricht dem Versatz zwischen Drehachse und Lenkachse.These cars run on the floor with four wheels. Two of the roles are rigid. In the case of rigid castors, there is an axis of rotation of the wheel rigidly connected to the car. Two castors are castors educated. These roles have one additional axis of rotation as the steering axis perpendicular to the axis of rotation of the wheel. When cornering of the carriage, the castor can pivot by turning itself the roller rotates around the vertical axis. The axis of rotation of the The wheel and the steering axle are offset from each other, so that when driving the axis of rotation runs to the steering axis. Cornering and simple maneuverability is made possible. Becomes if the direction of movement of the carriage is changed by 180 °, the roller swivels by 180 ° and guide the steering axles of the rollers a sideways movement during this pivoting movement. The size of the sideways movement corresponds to the offset between the axis of rotation and the steering axis.
Diese Seitwärtsbewegung des Wagens wirkt sich in verschiedenen Situationen störend aus. Einkaufswagen sind nach der Benutzung ineinander geschoben, so dass eine Reihe abgestellter Wagen entsteht. Der letzte Wagen der Reihe wird zur Benutzung rückwärts herausgezogen. Die Bewegung ist um 180° entgegengesetzt zu der Bewegung beim Abstellen. Die Lenkrollen des Wagens führen eine Schwenkbewegung aus und der Wagen führt beim Herausziehen eine Seitwärtsbewegung aus, so dass der Wagen an die anderen Wagen der Reihe anstößt. Dadurch klemmt der Wagen und die Rückwärtsbewegung wird behindert.This sideways movement of the car affects disturbing in different situations out. Shopping carts are pushed into one another after use, so that a row of parked cars is created. The last car the row is pulled out backwards for use. The movement is opposite by 180 ° to the movement when parking. The castors of the car swivel and the car leads a sideways movement when pulling out off, so that the car bumps into the other cars in the row. Thereby the car gets stuck and the backward movement is hindered.
Aufgabe der Erfindung ist es, eine Lenkrolle der beschriebenen Art zu gestalten, die jedoch keine Seitwärtsbewegung des Wagens bei einem 180° Richtungswechsel bewirkt.The object of the invention is a Design swivel castor of the type described, but no sideways movement the car during a 180 ° change of direction causes.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This task is due to the characteristics of claim 1 solved.
Die Lenkrolle weist eine Drehachse für das Rad und eine Lenkachse für die Schwenkbewegung auf. Die Drehachse und die Lenkachse stehen senkrecht zueinander. Beide Achsen sind mittels Linearführung miteinander verbunden. Dadurch ist Drehachse mit Rad zu der Lenkachse linear verschiebbar. Der Verschiebeweg wird durch Anschläge begrenzt und die Länge des Verschiebeweges entspricht etwa dem doppelten des Versatzes zwischen Dreh- und Lenkachse bei Lenkrollen aus dem Stand der Technik. Bei einem Richtungswechsel der Wagenbewegung um 180° wird zunächst die Lenkachse linear zur Drehachse mit Rad verschoben bis die Lenkachse die Drehachse mit Rad in die geänderte Richtung zieht. Aufgrund der Linearbewegung führt der Wagen keine störende Seitwärtsbewegungen aus. Bei Kurvenfahrt des Wagens kann die Rolle Schwenkbewegungen aufgrund der Lenkachse ausführen, ohne dass die Linearführung die Lenkbewegung beeinflusst. Die Lenkrolle verhält sich wie eine Lenkrolle ohne zusätzliche Linearführung entsprechend dem beschriebenen Stand der Technik.The swivel castor has an axis of rotation for the bike and a steering axle for the swivel movement. The axis of rotation and the steering axis stand perpendicular to each other. Both axes are connected to each other by means of a linear guide connected. As a result, the axis of rotation with the wheel is linear to the steering axis displaceable. The displacement is limited by stops and the length the displacement path corresponds approximately to twice the offset between pivot and steering axis in swivel castors from the prior art. When the direction of the carriage movement changes by 180 °, the Steering axis shifted linearly to the axis of rotation with the wheel until the steering axis Axis of rotation with wheel in the changed Direction pulls. Due to the linear movement, the carriage does not have any disturbing sideways movements out. When the car is cornering, the roller can swivel due to the steering axis, without the linear guide affects the steering movement. The swivel castor behaves like a swivel castor without additional linear guide according to the described prior art.
In den Abbildungen ist eine Ausführungsform der Erfindung dargestellt.In the figures is an embodiment of the Invention shown.
In
Die störende Seitwärtsbewegung wurde somit vermieden.The annoying sideways movement was thus avoided.
