EQUIPMENT TO GO ON GRASS-GROWN j NOT WITH SNOW COVERED HOPE TO SKI

The present invention relates to equipment to grassy, not covered with snow slopes ski to run. .

At the moment it is not possible to walk on grassy slopes, that are not covered in snow, to ski ,, to practice this sport even in areas with little or no ' To be able to practice snowfall, plastic slopes were made, on which you can ski without snow.

These slopes have the disadvantage that their production costs are very high. .

Eirj. Another disadvantage is that of the skier must follow a certain, limited slope, in addition, on these slopes not the usual, used on skis used on snow. So there are currently only two ways to ski: on slopes covered with snow or on plastic posts.

The present invention aims to make skiing possible even on grassy slopes not covered with snow available.

To do this, the technical problem had to be solved, on one grassy slope not covered with snow "the same to maintain the physical conditions that occur between the ski and the ground on a slope covered with snow ,

These conditions consist in the fact that there is a thin layer of liquid between the running surface of the skis and the ground. Snow-covered slopes will do this met by the surface of the snow layer, the present invention provides that the concerned Equipment and the associated skis are designed in such a way that this layer of liquid, which is on a grassy, slope not covered with snow obviously not

hand is to produce artificially; that will be preferable obtained by a solution of a detergent that can be broken down into organic substances in water. .

The present invention consists of equipment that enables skiing on grassy, not covered with snow Hanging out, which is characterized by the fact that it consists of the following parts: a pair of rather short ones Skis, the blades of which are each covered with a coating, the inner surface of which has a cavity with the running surface forms that opens into a gap at the rear; one or more liquid containers similar to the above Cavities are connected so that the liquid flows down by gravity into these cavities and then through the gaps on the tread 'get.

The characteristics of the present invention are evident from

following, exemplary description with reference to the accompanying drawings "It shows:

Fig. 4: an embodiment of the equipment according to the present invention Invention, in particular a ski in longitudinal section;

Figures 5 and 6: further two embodiments of the equipment according to the present invention, in particular one Ski in side view and partly in section. With reference to Figures 1 to 3, the equipment according to the present invention described in a first embodiment .

It can be seen from these figures that the equipment consists mainly of a pair of skis, both of which are labeled 1 are.

The skis 1 are shorter than the conventional ones on snow used skis,

The front, curved shovel la of each ski 1 is partially covered by a cover 2 which is folded over the upper part of this shovel. The inner surface 2a of this coating forms with the lower surface of the ski 1 a cavity 3 which opens at the rear in a gap k .

The blade la has an opening 5 to the cavity 3 ai> f. A connection 6, in which a hose line 7 snaps into place, is attached to this opening 5.

The equipment also consists of a, container 8, the absorbs a liquid; From this container 8 with closure 8a come the hose lines 7, which are on the connections 6 click into place »

On each hose line 7 means are provided to the to regulate the liquid coming from the container 8; In the case shown, these means consist of taps 9 " The container 8 is carried like a rucksack and is equipped with a shoulder strap 10 and a strap II.

The hose lines 7 are narrow with the help of straps 12 attached to the legs.

According to a further embodiment, not shown, is instead of the container 8, a small jacket worn by the skier is provided, the waterproof pockets for receiving the liquid, from which the hose lines 7 extend.

According to a further embodiment shown in FIG. H , the container for each ski consists of one or more containers 13 which are machined from the ski. The containers 13 are connected to one another via the openings 14. One of the containers is provided with a closure 13a which is removed in order to fill the container. The container 13 resting on the shovel la of the ski 1 is

through the line 15 and the opening 5 with the cavity 3 tied together.

According to further embodiments shown in FIGS. 5 and 6, the container for each ski consists of a container 16, which is attached to the rear of the top of the ski, or from a similar container 17, which is attached to the front of the ski top is attached «The containers 16 and 17 each have a waterproof screw cap 16a and 17a. on A front container 17 and a rear container 16 can also be provided for each ski 1 the two containers by a row or several hose lines connected, which are attached to the ski.

In all cases the containers stand by one or more Hose lines 18 or pipes 19 and through the opening 5 with the cavity 3 in connection.

These lines 18 have inside means for the amount of liquid to regulate, the ζ, B, consist of the taps 20.

When using the equipment, the skier provides assistance of the taps 9 and 20 the desired flow rate of the liquid in the hose lines 7 or 18 such that the Liquid flows through the opening 5 into the cavity 3, and flows out through column 4.

In the case of the container 17, the closure 17a is screwed on slightly, so that the air entering the container causes the liquid to flow out through the conduit 19 ο n

In this way, the liquid wets the ski's running surface, creating a thin layer on it, that allows skiing on grassy slopes.

The liquid preferably consists of a solution a detergent that can be broken down into organic substances in Water"

The use of short skis, for example with a length 90 cm is recommended for two main reasons:

A) It is easier to remove the thin layer of liquid on a 90 cm long running surface than on the 2 meter long running surface of ordinary skis. Also reduced the friction between the running surface and the floor is proportional to the expansion of the running surface.

B) Skiing is made much easier with short skis.

The following is a description of an embodiment of the equipment that could be used to ski for about 30 minutes. The equipment consisted of one worn by the skier
