Abstract

The rollers' spacing in a given direction grows larger. The carrier wedges of a housing guide are pressed into the running groove on loading the device. Simultaneously with rotation of the rollers, the roller gap is altered in a given direction. The axial movement of the rollers comes to a stop after the carrier wedges have moved from the spiral grooves into the radial grooves.

Description

Stand der TechnikState of the art

Schaut man sich heutzutage einmal an Bahnhöfen und Flugplätzen um, so stellt man fest, daß die Zahl der Reisenden erheblich zugenommen hat. Dabei werden auch viele Güter, vorwiegend in Koffern, transportiert.Nowadays you take a look at train stations and Airfields, it can be seen that the number of Travelers has increased significantly. In doing so, too many goods, mainly in suitcases, are transported.

Früher wurden die Koffer von Kofferträgern geschleppt, heute erledigen diese Aufgabe sogenannte Kofferkulis, die man gegen eine Leihgebühr benutzen darf.The suitcases used to be towed by panniers, Today, so-called luggage trolleys do this task you can use it for a rental fee.

In der Praxis wird jedoch sehr selten darauf zurückgegriffen, weil die meisten Reisenden nur je einen Koffer mit sich führen und den kann man ja tragen. Nun diesen Umstand hat sich auch die Industrie zunutze gemacht und an ihre Koffer einfach ein paar Rollen integriert. Wer allerdings schon einmal so einen Koffer gezogen hat, der weis, daß dies gar nicht so einfach ist. Der Koffer hat nämlich die Eigenschaft, daß er wenn schwere Gegenstände oben liegen oder man die Richtung ändert, leicht umfallen kann. Dies ist im besonderen bei schmalen und hohen Koffern zu beobachten. Die Ursache für dieses Verhalten liegt in der geringen Achsbreite des Fahrwerkes. Leider lassen sich die Rollen nicht beliebig nach außen versetzen, da der Koffer sonst zu sperrig wird und einen unnötigen Raumbedarf hat.In practice, however, it is very rarely used because most travelers only have one suitcase with them lead and you can wear it. Now has this fact the industry also took advantage of their suitcases simply integrated a few roles. But who does once pulled a suitcase that knows that this is even possible is not that easy. The suitcase has the property that if there are heavy objects on top or if the Changes direction, can easily fall over. This is in especially to observe with narrow and high suitcases. The reason for this behavior is the minor Axle width of the chassis. Unfortunately, the roles do not move them outwards as the case will otherwise close becomes bulky and takes up unnecessary space.

Vorteile der ErfindungAdvantages of the invention

Die beiliegende Konstruktion hat die Aufgabe das "Fahrverhalten" des Koffers zu verbessern ohne dabei die Stapel bzw. Abstellbreite zu verändern.The enclosed construction does the job To improve the "driving behavior" of the suitcase without losing the To change the stack or storage width.

FunktionsbeschreibungFunctional description

Das Prinzip dieser selbsttätig ausfahrenden Rollen beruht auf der Schwerkraft. Wird der Koffer auf den Boden gestellt, so drückt der Mitnehmerkeil (1) auf die Läufer (2). Beim Ziehen des Koffers dreht sich der Läufer, der Mitnehmerkeil greift in die Wendelnut und der Läufer wird nach außen transportiert. Der Vorteil dieses Prinzips liegt darin begründet, daß für das Ausfahren der Rollen nur eine geringe Kraft benötigt wird, die je nach Koffergröße über die Steigung der Wendelnut verändert werden kann. Die Rollen bewegen sich nur in axialer Richtung wenn eine Drehbewegung der Rollen zu verzeichnen ist. Ein gleicher Effekt ist bei Automobilen zu sehen: Keiner (ohne Servolenkung) müht sich ab, das Lenkrad im Stillstand zu drehen, auch hier geht es schon bei langsamer Vorwärtsbewegung wie von selbst.The principle of these automatically extending rollers is based on gravity. If the case is placed on the floor, the driver wedge ( 1 ) presses on the runners ( 2 ). When the case is pulled, the rotor rotates, the driver wedge engages in the spiral groove and the rotor is transported to the outside. The advantage of this principle lies in the fact that only a small force is required to extend the rollers, which force can be changed via the pitch of the spiral groove depending on the size of the case. The rollers only move in the axial direction when there is a rotational movement of the rollers. The same effect can be seen in automobiles: Nobody (without power steering) struggles to turn the steering wheel at a standstill, even here, with slow forward movement, it goes by itself.

Sind die Läufer ganz nach außen transportiert, so laufen die Mitnehmerkeile (1) in eine radiale Nut und die Axialbewegung kommt zum Stillstand. Ist der Zielort erreicht, so hebt man den Koffer an, die Läufer fallen nach unten und der Mitnehmerkeil (1) kommt außer Eingriff. In diesem Fall lassen sich die Rollen ohne Widerstand von der eingebauten Feder (3) nach innen ziehen.If the runners are transported all the way to the outside, the driver wedges ( 1 ) run into a radial groove and the axial movement comes to a standstill. When the destination is reached, the case is lifted, the runners fall down and the driver wedge ( 1 ) disengages. In this case, the rollers can be pulled inwards by the built-in spring ( 3 ) without resistance.
