Abstract
Abstract A long, flat, thin board, which may be shaped into a toboggan by the ultimate user, is formed by bonding together a pair of polyethylene sheets, the lower of which is ribbed to form runners and the upper of which is ribbed to form transverse braces, the bonded marginal edges of the sheets being arched upwardly at intervals to provide support for a rope-type handrail which is also used as a means for holding the forward end in a reversely curved upright position when it is desired to use the board as a toboggan.
