The invention relates to one of several individual In the ski according to the invention can thus one share composite ski, which is made of elastic, simple form and therefore easy to manufacture springy Material-made edge strips openable cover sheets are used, with only has, which with an upper and a lower one more flat cranking of the edges of the lower one Metal cover sheet or possibly reinforced cover sheet is necessary. The point of this offset Synthetic resin to form the ski support body essentially consists in inserting the Box girders are connected in such a way that the edges edges of the cover sheet into the lower groove of the edge of the upper and lower cover sheet at least in the afford with the underside of the edge strips To enable the shovel area from a lower cover sheet aligned in the edge strips. the brought wide groove and that ίο flat cranking of the edges of the lower cover sheet the lower cover sheet with the underside of the strips practically does not increase the flexural strength in alignment and has upwardly cranked edges. ability of the ski. The spring properties of the ski are

In a known ski of this type, the cross-sectional shape and cover sheets essentially consist of pressed sheet metal parts, the lower one having the cross-sectional height in the various longitudinal cover sheet a U-shaped cross-section with flanges angled off from the edge strips after 15 regions of the ski and with that, a further box girder is also connected by the groove guide, in particular the flat upper cover sheet to a special guide of the upper groove. The side flanks of influencing the spring properties is possible. The claim only protects the bending strength of the box girder transversely to the longitudinal 20 velvet combination of its features,

of the lower cover sheet is covered by the edge strips. Two from the tip of the ski to the rear end of the ski, the ski body is given an essentially rectangular shape of the edge strips 1, 2 at the tip of the ski. In addition, the edge strips, indirectly and at the end of the ski, serve as a holder for edge reinforcements. one profiled in accordance with the edge strips 1, 2. The ski body has a height that decreases at the ends from the binding area according to the spacer 3 to a resilient support frame, in order to allow the bending connection. On the underside, the edge stiffness of the ski body has grooves 4 in the various strips 1, 2, into which the angular longitudinal edge areas of the ski can be adjusted in accordance with the required reinforcements 5 with one leg inserted and in order to make the ski cheap. Driving characteristics are to be given on the sides facing each other. In practice 35 shows the edge strips 1, 2 and the spacer 3 close but that despite the corrugation of the flanks of the lower the upper and lower edge with horizontal cover sheet received too great a flexural strength grooves 6 and 7, provided in the cover sheets 8 or 9 remains, since above all the wall thickness of the cover sheets engage with their edges and are not fastened under by gluing in order to avoid dents. The edges 10 of the lower deck can be reduced to a predetermined amount. 40 sheets 9 are cranked upwards, so that the lower edge strips 1 and 2, especially the lower cover sheet, must be flush with the undersides of the guide made as a separate pressed sheet metal part on this outside of the cover sheet 9. As can be seen, if different bending stiffnesses increase the height and thus the cross-section of the different skis, each edge strips of the binding area (cross-section III) have their own molds for the production of this lower part against the shovel. In the area of the shovel partly required, which the production considerably, therefore the two grooves 6 and 7 to one are expensive. A finely tuned adjustment of the common ski groove 6 α combined, in which the edges of the properties with regard to the use of the two cover sheets 8 and 9 lie against one another. For the purpose and depending on the weight of the deck driver, which is preferably made of metal, because of the high tool costs and 5 ° blades, a support 11 made of synthetic resin, which is practically withstood between the edge strips because of the excessive bending stiffness, is included at the top and at the bottom. up to the edge reinforcements 5, even
