Abstract

The blades are mounted on the axles of the roller skate in place of the rollers and thus permit ice skating using the same device with the same technology but without the overstraining of the lower leg and of the ankle which is known from ice skates with one blade. Each foot stands on four blades without tipping over.

Description

Kufen für ein mehrkufiges Wintersportgerät mit lenkbaren Achsen.Skids for multi-skid winter sports equipment with steerable axles.

Solche Kufen für ein Wintersportgerät mit lenkbaren Achsen, welches vornehmlich durch Umbau von Rollschuhen oder Roller-Skates hergestellt wird, sind bisher nicht bekannt. Es ist bekannt, daß solche Sportgeräte durch Austausch der Rollen gegen Kufen für den Wintersport geeignet sind.Such runners for a winter sports device with steerable axles, which is primarily made by converting roller skates or roller skates not yet known. It is known that such sports equipment by replacing the Rolls against runners are suitable for winter sports.

Dieser Erfindung liegt die Aufgabe zugrunde, Kufen zu entwickeln, mit denen sowohl auf hartem Kunsteis wie auch auf weichem Natureis die verschiedensten Anforderungen erfüllt werden.This invention is based on the task of developing runners, with those on hard artificial ice as well as on soft natural ice the most varied Requirements are met.

Die zu erfüllenden Forderungen sind: Die Kufen sollen anstatt der Rollen auf denselben Achsen montiert werden.The requirements to be met are: The runners should instead of the Rollers can be mounted on the same axles.

Das Eis darf bei den verschiedensten Laufübungen nicht beschädigt werden.The ice must not be damaged during the various running exercises will.

Die Kufen sollen bei Geradeauslauf schnell sein und in den Kurven nicht wegrutschen.The runners should be fast when running in a straight line and when cornering do not slip away.

Die Kufen dürfen auch bei beschädigtem Eis nicht einhaken.The runners must not get caught even if the ice is damaged.

Die Verletzungsgefahr durch die scharfen Kanten der üblichen Schlittschuhkufen soll gemindert werden.The risk of injury from the sharp edges of the usual skate blades should be reduced.

Alle diese Eigenschaften müssen beim Vorwärts- und Rückwärtslaufen gleichgut erreicht werden.All of these properties are required when running forwards and backwards can be achieved equally well.

Erfindungsgemäß werden hierzu die folgenden Kufen vorgeschlagen: Figur 1 zeigt die Kufe 1 in Ansicht.According to the invention, the following runners are proposed for this purpose: Figure 1 shows the runner 1 in view.

Figur 2 zeigt einen Schnitt durch die Kufe 1 längs der Linie A - B.Figure 2 shows a section through the runner 1 along the line A - B.

Figur 3 zeigt den Schnitt längs der Linie A - B durch eine Kufe mit zwei ebenfalls gekrümmten parallelen Schneidekanten 12 + 13.Figure 3 shows the section along the line A - B through a runner with two also curved parallel cutting edges 12 + 13.

Die Bohrung 2 dient der Aufnahme der Kufe auf der Achse. Die Schneidenkante 3 weist eine Krümmung 4 auf. Die beidseitigen Schrägen oder Radien 5 und 6 dienen dem Aufgleiten der Kufe. Der Schneidenwinkel 7 erlaubt das Eindringen in die Oberfläche des Eises. Die Durchbrüche 8 bedeuten Gewichtsersparnis. Die Wülste 9 und lo, z.B. aus Kunststoff angespritzt, verhindern im Falle einer Verletzung, ein tieferes Eindringen der Kufe, als es der Abstand 11 gestattet.The hole 2 is used to receive the runner on the axle. The cutting edge 3 has a curvature 4. The bevels or radii 5 and 6 on both sides are used the sliding of the runner. The cutting angle 7 allows penetration into the surface of the ice. The openings 8 mean weight savings. The beads 9 and lo, e.g. Molded from plastic, prevent deeper penetration in the event of an injury of the skid than the distance 11 allows.
