Abstract

A ski (2) make of plastic has a layer of foamed plastic on its outer surfaces (4, 5) and steel strips (6) along the edges of the undersurface. The undersurface has a coating of plastic in which glass beads of about 0.2 to 0.3 mm dia. are embedded. The beads are packed close together so that they are in contact with each other. The outer layer of beads project slightly through the plastic layer and produce an appearance of fine emery, cloth. The glass used has a hardness of 7 to 8 on Mohs' scale. The use of glass beads produces good running properties on all types of snow surfaces and does not need coating with special waxes as is required with conventional plastic coated skis.

Description

Gleitbelag aus Kunststoff für Gleit- Plastic sliding coating for sliding

körper auf Schnee und Eis, insbesondere für Ski Die Erfindung bezieht sich auf einen Gleitbelag für Skier oder andere auf Schnee und Eis gleitend bewegbare Körper, whe z. B. Eisstöcke, Schlitten oder dergleichen. body on snow and ice, especially for skis The invention relates slidable on a sliding surface for skis or others on snow and ice Body, whe z. B. ice stocks, sledges or the like.

Die bisher verwendeten Gleitbeläge aus Kunststoff erfordern zur Verbesserung der Gleitfähigkeit und insbesondere zur Verhinderung einer zu starken Schneehaftung regelmäßiges-Wachsen, wobei je nach den Schnee- und Temparaturverhältnissen unterschiedliche Wachse verwendet werden müssen. The plastic sliding linings used to date require improvement the sliding ability and in particular to prevent excessive adhesion to the snow Regular waxing, although different depending on the snow and temperature conditions Waxes must be used.

Aufgabe der Erfindung ist es, einen Gleitbelag für Gleitkörper zu schaffen, der ein Wachsen der Gleitfläche überflüssig macht. The object of the invention is to provide a sliding coating for sliding bodies create that makes waxing the sliding surface superfluous.

Diese Aufgabe ist dadurch gelöst, daß in den Kunststoff der Gleitfläche kleine Glasperlen derart eingebettet sind, daß sie jeweils zur Außenseite als Kugelkappe vorstehen. This object is achieved in that the sliding surface in the plastic small glass beads are embedded in such a way that they each face the outside as a spherical cap protrude.

Hierdurch wird dem Schnee die Haftungsmöglichkeit genommen, wobei bei richtiger Wahl der Glasperlengröße und der günstigsten Verteilung keine Beeinträchtigung der Gleiteigenschaften, vielmehr deren Verbesserung erreicht wird.This deprives the snow of its liability, whereby with the correct choice of the glass bead size and the most favorable distribution, no impairment the sliding properties, rather their improvement is achieved.

Vorteilhaft haben die Glasperlen eine Größe in der Größenordnung von 200 bis 300 Die Verteilung der Glasperlen wird zweckmäßig so gewählt, daß benachbarte Perlen einander seitlich berühren. The glass beads advantageously have a size of the order of magnitude from 200 to 300 The distribution of the glass beads is expediently chosen so that adjacent Pearls touch each other laterally.

Die Erfindung wird im folgenden anhand einer schematischen Zeichnung näher erläutert, die einen Querschnitt durch einen Ski sowie in vergrößertem Maßstab ein Detail des Gleitbelags zeigt. The invention is illustrated below with reference to a schematic drawing explained in more detail, showing a cross section through a ski and on an enlarged scale shows a detail of the sliding lining.

Der Gleitbelag 1 bildet die Sohle eines Skis 2 und besteht aus Kunststoff, in den kleinste Glasperlen 3 mit einem Durchmesser in der Größenordnung von 200 bis 300 p eingebettet sind, so daß sie mit einer Kugelkappe aus der Gleitfläche des Belags vorstehen und mit dem Hauptteil ihres Körpers verankert sind, der durch seine Kugelform hierfür die notwendigen Hinterschneidungen bietet. Die Verteilungsdichte der Perlen wird zweckmäßig so gewählt, daß sich die einzelnen Perlen gegenseitig stützen. Man erhält auf diese Weise eine der Art eines feinen Schmirgelpapiers ähnliche Oberfläche. The sliding coating 1 forms the sole of a ski 2 and consists of plastic, in the smallest glass beads 3 with a diameter of the order of 200 to 300 p are embedded, so that they can be removed from the sliding surface with a spherical cap protruding from the pavement and anchored to the main part of their body passing through its spherical shape offers the necessary undercuts for this. The distribution density the pearls is expediently chosen so that the individual pearls are mutually exclusive support. In this way, a kind of fine emery paper is obtained Surface.

Die Perlen sind vorteilhaft auf eine mHos-Härte von 7 bis 8 gehärtet. The pearls are advantageously hardened to a mHos hardness of 7 to 8.

Der Gleitbelag läßt sich bei jeder Art von Ski anwenden, Im dargestellten Fall handelt es sich um einen Kunststoffski, der aus einem aus Oberbelag 4, Gleitbelag 1 und Seitenteilen 5 gebildeten Kasten besteht, der ausgeschäumt ist. Das Bezugszeichen 6 bezeichnet übliche Stahlkanten. The sliding coating can be used with any type of ski, Im shown The case is a plastic ski, which consists of a top surface 4, sliding surface 1 and side panels 5 is formed box that is filled with foam. The reference number 6 denotes common steel edges.
