Claims

1 ■ ■ 2 firmly connect with one another, the main claims and patent claims:. Do not shift the lower chord against each other significantly, which is necessary for a good snake effect.

1. Ski, consisting of upper and lower belt with agile.

Inlays between the two, which are known. The object of the invention is to provide a ski

draws that the upper and lower belt (1 a, to create the type mentioned, which is sufficient

IZ? or 2 a, 2 b) only in the area of the binding flexural and torsional strength a high snake

as well as at the top (3) and at the end (8) of the effect, especially at high

Skis are firmly connected to each other so that the running speeds as a result of the good

inserts (7.7 a, io that are used to keep the distance) nestle against the flapping of the ski.

Tb; 14 ') are loosely inserted and that top and can be knitted.

Lower belt and inserts from a plastic This object is achieved according to the invention

Gehäusc (9) are surrounded. solves that the upper and lower belt only in the area

2. Ski according to claim 1, characterized gekennzeich- the binding and at the top and at the end of the net that the inserts (7.7 a, 7 b), for example strips 15 skis are firmly connected to each other, that the made of wood or Metal, in the area of the ski binding, inserts serving to maintain spacing are loosely inserted under them and with the straps (1 a, 1 b and 2 a, and that the upper and lower strap and inserts of 2 b) are firmly connected (Fig. 3) . are surrounded by a plastic housing.

3. Ski according to claim 1, characterized in that the structure of the ski is based on the knowledge that between the top belt (la, 1 b) and the bottom 20 grounds that there are several for a high snake effect of the belt (2 a, 2 b) Bar parts (14 ') of preferred skis is decisive, upper and lower chords are only loosely inserted into grooves (19) of the chords at the absolutely necessary points with one another (Fig. 5). to connect firmly, which is why the deposits between

The upper and lower chords are not connected to them and therefore the bending and ^ mutual

Do not prevent the upper and lower belt from being pushed.

Details of the invention are given below with reference to preferred exemplary embodiments Description in connection with the drawing

The invention relates to a ski consisting of 3 ° explained in more detail. Show it
Upper and lower belt with inserts between the two. Fig. 1 and 2 schematic representations for the creation

There are known skis which, in order to clarify the weight of the concept of the invention ·
reduction are hollow. Since this, however, FIG. 3 shows a schematic representation of a

the top chord under pressure load to the outside or skis according to the invention in side view,
can bulge inside, the rigidity of the ski 35 Fig. 4 a cross section is impaired by a further bulge. Therefore, hollow skis were introduced on a larger scale,
were, for example in the form of webs, honeycomb- Fig. 5 shows a cross-section like Fig. 4, but with

shaped foils, etc., provided. differently trained deposits.

The problem with the known types of ski is that the ski shown in FIG. 1 has an upper

flutter plays an essential role. Slightly stiff 40 chord 1 and a lower chord 2. Both are at the At higher speeds, skis tend to tip 3 and at the (not visible) end of the ski strong to flutter. If the stiffness is higher, it will fit together rigidly, for example with but the ski glued together less well, and in the area of the binding and evenness of a ski slope and conveys it about in the middle area of the ski via a Skiers have a hard, uncomfortable feeling when running. 45 web part 4 also rigidly connected to one another. the

In order to achieve a good adaptation of the ski to unevenness of the upper and lower chord 1 or 2 in front of and behind, a ski with several spaces enclosed after the web part 4 is known from layers of withstanding material without any noteworthy bending. However, such a ski has a low level of stiffness. If the lower chord 2 experiences rigidity, as a result of which a regulation of the suspension of the 5 °, the crossing of a raised ground at the point of individual layers below and opposite that of the arrow 5, the running rail in dash-dotted line in FIG. 1 is necessary. This leads to a marked deflection, so this results in a uncomplicated structure that is unusable in practice. Speaking shortening of the original Ab-To suppress the flutter and at the same time a stand A ₁ between the bridge part 4 and tip 3 of the ski putes adapting the ski to the unevenness of 55 to the new distance A " with tip position 3". To reach the ski slope, a ski of the upper chord 1 is finally known due to the spacing material, the upper chord or lower chord of which is bent out from over- correspondingly and can move freely against one another metal and rubber layers over the lower chord 2, if it consists of layers. As a result, when the skis slide into the dash-dotted position shown in ^FIG 'This ski was essentially referred to as the "snake neck". borrowed retains. In particular, the tip 3

The rubber layers exercise a dampening effect due to the elevation of the floor; not like a hcr-action, but they reduce the torsional ability of the ski to be lifted off the ground, and the strength of the ski. Therefore, the possibility of making a high rise with its tip 3 on the ground is always possible when driving over such a ski with a strong snake. Furthermore, since the ski deposits are upright and behave as it is in F i μ. 2 illustrates looking wooden strips that are top and bottom chords. A normal ski is also shown here with a dashed line.
