DESCRIPTION:
BRIEF SUMMARY
The invention relates to the means used for practising winter sports, particularly to equipment for a monoski or twin skis.
Since the main aim of using a monoski is to descend a slope, it is essential to climb to a high point before preparing to descend it.
The user of a monoski cannot put it on until he leaves the car of a cableway or a chair-lift seat which has carried him to the top of the slope; he is prohibited from being towed by a ski-lift with poles for obvious reasons of safety, as much for his own sake as for that of the other skiers wearing separate skis.
The purpose of the equipment according to the invention is to allow the user of a monoski to be towed by a ski-lift with poles, by guiding the monoski with one foot, a pilot ski being worn on the other foot.
This equipment is characterized in that at least one pilot ski, the dimensions of which are inscribed within the perimeter of the face of the monoski opposite the sliding sole and which is fitted with a safety fastening, is arranged removably on the said face of the monoski being held in place by quick-release means, and in that the pilot ski can easily be detached from its support for parallel use in accompaniment, thus making it easier to guide the assembly consisting of the monoski and pilot ski.
The means used to hold a pilot ski on the monoski comprise at least three elements, namely a hook-shaped stop located on the same side as the heel of the pilot ski, a sling-shaped elastic loop located on the same side as the tip of the pilot ski, the two fastening points for the loop being arranged on either side of the pilot ski at a sufficient distance from the stop to ensure that the elastic force exerted by the pocket of the sling on the tip of the pilot ski keeps its heel effectively up against the stop, and at least one strap which straddles the pilot ski and the function of which is to lay the pilot ski against the face of the monoski opposite the sliding sole.
In another embodiment, the monoski has, on its face opposite the sliding sole, two imprints parallel to its edges and having exactly the dimensions of two standard skis duly fitted with safety fastenings, suitable means keeping the two skis firmly in the imprints of the monoski, whilst at the same time allowing the standard skis to be separated quickly from the monoski.
The main advantages of such monoski equipment are that slopes can be climbed in ways other than by the sole means of cableways with cabins or other chair-lift systems.
Other advantages will emerge from the description of embodiments given by way of non-limiting examples and from the drawing in which:
FIG. 1 is a plan view of a monoski equipped with one or two pilot skis,
FIG. 2 is a profile view of the monoski of FIG. 1,
FIG. 3 is a partial view of the means of fastening a pilot ski to the monoski.
The monoski 1 illustrated in FIGS. 1 and 2 has a pilot ski 2 located between the front fastenings 5 and the tip 100 of the monoski. It also has a position for a second pilot ski 3, represented by dotted lines, located between the rear fastenings 4 and the heel 101 of the monoski 1.
The pilot skis 2, 3 are held against the face 102 of the monoski opposite the sliding sole 103 by at least three means interacting with one another, namely 300 of the pilot ski in order to push it against the stop 6; the monoski.
In general terms, to prevent the pilot ski from shifting the center of gravity of the assembly comprising the monoski and pilot ski, the heel 201, 301 of the pilot ski 2, 3 is placed between the rear fastenings 4 and front fastenings 5 of the monoski. In fact, the rear part of the pilot ski 2, 3, that it to say the heel 201, 301 supporting the rear fastening 10 of the pilot ski 2, 3, is heavier than the front part.
FIG. 3 shows in detail these three means of fastening the pilot ski.
The stop 6 has a notch (not shown) into which the heel 201, 301 of the pilot ski 2, 3 penetrates under the effect of the elastic force F.
The sling 7 has a pocket 700, into which the end of the tip 200, 300 is introduced; the two elastic st
