DE2602634A1 - Ski stick tip with profiled rims - has cylindrical or conical body with circumferentially stepped edges - Google Patents

Abstract

The ski stick tip consists of a cylindrical or conical body, the free end of which has two or more stepped circumferential edges (4). The body may be oval or polygonal, with a concave end face. Alternately, the body may consists of several truncated cones (6), positioned above each other, with the bases facing the tip end. The exterior surfaces of all bodies may be profiled or toothed. The profiled design gives a better grip on the ice than the normal single profile design.

Description

Designation: ski pole tip with raised, non-gripping

speed and reduced risk of injury are the subject of the invention is a ski pole tip that, thanks to its special shape, forms the penultimate hole for the skier considerably from indert, and at the same time on hard snow or Ice grips better than any previously known system. On the kraut more and more icy, Well-traveled downhill pistes have a particularly good grip on ice Interpretation. Ski poles that slip away on ice are not just great exhausting - when the arm stumbles into the void - but also prone to falling over.

This applies not only to the descent, but also to ascents in hard or icy track. However, it is also particularly important that the tip of the ski pole because of the risk of injury to the skier (including children), is as blunt as possible.

As a defused alternative to the conventional cone tips are recently known so-called crown tips, but their grip is too weak especially if c; it leaves a cavity between the individual prongs, the so-called Crown is soiled on aperen and then iced up. Are the prongs however sharp, their danger to injuries is hardly less than with cone tips.

Recently related ring points have also been used instead of crown prongs a ring edge with a centrally turned crater-shaped recess. through this the ring edges are mostly very sharp and point with their cutting from the stick handle seen down.

In the case of a fabric, size in the direction of the longitudinal axis of the ski pole This type of trained stick tips act like gouges and thus when they hit easily cause injury to a body. Also, sit down, similar to Already mentioned at the so-called crater peaks, in the recess, especially when dirty and at unfavorable temperatures, slightly seal-like ice caps on, which reduce the grip almost completely. Chipping off or scraping off the ice during the use of sticks, because of the seal-like crater recess in which the dirt and the ice claw in, hardly or not at all, because of it the mentioned ice seal can hardly attack lateral forces.

The inventor has set himself the task of the disadvantages mentioned to avoid the mentioned ski pole tip.

Instead of the tip, the solution shows a cylindrical body with a free end one or possibly also several bodies of smaller diameter centrically are turned on.

This results in a wraparound edge, or

possibly several surrounding edges.

The greatly increased grip of two edges (double edge) on ice has recently been used by various ski manufacturers (e.g. Hexcell, Munich) recognized and applied to the ski.

These circumferential edges are preferably rectangular in cross-section, however, especially the surface 5 can be more or less due to a concave undercut be sharply designed to prevent dirt and ice from sticking - even in the hollow edges 7 - to avoid as much as possible, these can preferably be rounded off (see figure 4) Embodiments of the invention are shown in accompanying drawings and are described as follows: Figure 1: Side and top views of a ski pole tip according to the invention, its largest diameter corresponds to the lower outer diameter of the ski pole crochet.

Figure 2: Side and plan view, the former partially cut, one Design variant whose ski pole tip is larger in diameter than the outer diameter of the ski pole is, Figure 3: side and top view of an embodiment to Figure 2 Figure 4: Side and plan view of a further variant with more than two circumferential edges and rounded inner edges in the operating position (inclined position) grasping on the ice, drawn.

The increased grip of the ski pole tip according to the invention, even with a shallow angle of inclination between the ski pole and the driving plane (hard snow and Ice) is provided by the multiple rotating ones shown in the exemplary embodiments Edges (4) causes.

In order to avoid "rounding off" the edges due to abrasion, the tips are preferably made of hardened material.

The surfaces (5) visible in the top views (FIGS. 1-4) are preferred flat and at right angles to the tip axis, but can also be slightly concave be turned off.

The same is true of the various levels.

This makes the tip of the ski pole relatively 'blunt, the risk of injury is reduced considerably, and the build-up of T'is is prevented.

The preferably releasable connection of the ski pole tip to the ski pole tube (1) takes place in the usual way in that the body (2) at its upper end receives a centrally arranged, cylindrical or slightly conical shaft (3), which is pressed or glued into the tube (1).

Claims (5)

Claims 1. Ski pole tip, consisting of a preferably cylindrical or gel-shaped body (2), characterized in that on his free end two or more step-like circumferential edges (4) are present. 2. Ski pole tip according to claim (1), characterized in that the called bodies can also be oval or out of round, i.e. they can also be polygonal. 3. ski pole tip according to claim (1 and 2), characterized in that that the end faces of the or the cylindrical body (5) turned out concave will. 4. ski pole tip according to claim (1, 2 and 3), characterized in that that instead of the cylindrical body or bodies, one or more truncated cones (6) are arranged one above the other, with their base pointing towards the tip end. 5. ski pole tip according to claim (1, 2, 3 and 4), characterized in that that the outer surfaces of the cylinders or truncated cones in some form, e.g. by Knurling, profiled or serrated.
