Description

25th

The invention relates to a ski pole snow basket with a conical, round or polygonal one Washer made of elastic plastic, which starts in one piece jo from a hub attached to the ski pole and the when the ski pole is pushed into the snow, it opens like an umbrella and when the ski pole is pulled out from the snow folds up like a lace.

Such a Skistojk snow plate is known κ (CH-PS 4 39 048) and is intended to prevent the ski pole from penetrating too deeply into the snow. With the given configuration in connection with the provided elastically stretchable material, the desired effect occurs only when the ski pole is inserted exactly vertically into the snow and the pressure on the bell edge of the ski pole snow plate acts uniformly over the entire edge. When the ski pole is plugged in at an angle, an edge part is particularly heavily stressed, with the result that the plate washer tips over sideways and the desired plate stability is no longer guaranteed.

It is also already known (DE-OS 19 46 670) to produce the plate washer from individual to the hub pivotally mounted sheet-like segments which are v> during the pressing of the ski pole in the Snow stable and when snagging give or fold. The plate washer is made up of a large number of individual parts that require multiple, different processing and a relatively large amount of assembly work.

The use of an umbrella-like collapsible plate washer is also suitable for a water ski pole known (IT-PS 6 48 033), but the plate washer is provided with a linkage that is usual for umbrellas w) that helps stabilize the cup washer. Such a configuration is for a ski pole snow basket unusable.

Finally, a plate washer for a water ski stick is known (GB-PS 8 19382 and US-PS M 30 27 576), in which the plate washer extends in one piece from the hub and is made of elastic plastic so that the plate can fold up like an umbrella.

The plate washer is provided with stiffening ribs, but this is not guaranteed even with this plate washer, that when pushed into the snow a sideways evasion and thus a collapse avoided will.

The invention is based on the object in a ski pole snow basket of the type mentioned To improve umbrella-like folding when pulling the ski pole out of the snow and the To increase the stability of the snow plate when the S'dstock is pushed into the snow. This object is achieved according to the invention solved in that the plate washer is made of foldable plastic and by a A plurality of stiffening ribs extending radially in the cup washer is stiffened that the transition from the hub in the plate washer is designed as a film hinge, which is through a plurality of along the Transition extending openings is reduced in its cross-sectional strength, and that between the Stiffening ribs in the segment-shaped surface parts of the plate washer that are thereby delimited by them Openings are formed.

When the ski pole snow basket according to the features of the invention is achieved in an advantageous manner that this on the one hand as a result of the film hinge between the hub and on the other hand as a result of breakthroughs weakened and resilient segment-shaped surface parts between the stiffening ribs opens and closes easily and at the same time has sufficient plate stability to be able to use it at an angle the associated unequal edge load does not fold up or fold away to the side deformL

The invention is explained below using an exemplary embodiment in conjunction with a drawing described. This shows

F i g. 1 a ski pole snow basket in its normal position when the ski pole is inserted into the Snow;

F i g. 2 a folded plate washer;

F i g. 3 shows a section through the dividing disk along the line H-II in FIG. 1.

In Fig. 1 shows a washer 1 mounted on a ski pole in the opened position or in the normal position. The plate washer runs from the hub towards the outer edge, slightly inclined downwards, so that it has a flat, cone-shaped or umbrella-like shape. The plate washer 1 is stiffened by a multiplicity of stiffening ribs 3, the segment-shaped surface parts between the stiffening ribs 3 being provided with openings 4 and 5. As a result, the cross section of the plate washer 1 is weakened in the intended manner. A conventionally shaped hub 6 is connected to the cup washer 1 in one piece. The hub 6 is attached to a ski pole 1 .

If, in practice, the ski pole 7 is inserted into the snow cover in the direction of arrow D , the ski pole / snow plate remains stable and cannot give way or spring back upwards.

In Fig.2 the plate washer is in the folded state shown, it can be seen that the plate washer in the direction of the arrow sniffed through small obstacles can be pulled through or past such. This can be used in the snow or in the bushes Slightly pull the entangled snow plate out of the obstacle.

In Fig. 3 is a section along the line If-II of F ig. 1

I-shown, with the film hinge 9 located between the hub on the plate washer 1 can run. The plate grater folds during the folding process along this film hinge around, a real folding is supported by the fact that a

Number of openings 10 the cross-sectional strength in Weaken the area of the film hinge 9. On the left of the FIG. 3 is the plate washer in the folded up Condition and shown on the right in normal condition.
