Snowboard, surfboard, Monoski, water-ski and the like with very low weight and high mechanical strength

#The present invention relates to a snowboard with very low weight and high mechanical strength.

#Snowboards, surfboards, monoskis, water-skis and the like are conventionally manufactured according to two basic construction criteria which are derived from skiing: in particular, there are injection-molded boards and so-called sandwich boards.

#Injection-molded boards use a mold into which the materials that constitute the lower part and the upper part of the snowboard are placed, injecting polyurethane of appropriate density which, by expanding, forms the core of the board.

#Further characteristics and advantages of the present invention will become apparent from the following detailed description of a preferred but not exclusive embodiment of a snowboard with high mechanical strength, illustrated only by way of non-limitative example in the accompanying drawings, wherein:

#FIG. 1 is a schematic perspective view of the snowboard according to the present invention;

#FIG. 2 is a schematic sectional view of the snowboard;

#With reference to the above figures, the snowboard with high mechanical strength, according to the present invention, comprises a core 1 made of foamed plastics, which is preferably constituted by an expanded foam of structural polyvinyl chloride (PVC) with a relative density of preferably 100 kg/m3.

#In the tests that were conducted, the material that was found to be optimum is the one known commercially by the trade-name Klegecell, which is manufactured with densities between 55 and 130 kg/m3 and has optimum workability and gluing characteristics together with optimum mechanical strength.

#The best compromise between weight, deformability, structure and strength is achieved, as mentioned above, by using a material which has a density of 100 kg/m3.
