Abstract

A sleigh having an inflatable body which is wedge-shaped at its forward portion and parallel-sided at its rear portion, the body being subdivided into three inflatable compartments by two spaced longitudinally extending interior webs which slant outwardly relative to one another in their downward directions. The forward ends of the upper edges of the webs are slightly higher than their rear ends. The upper surfaces of the two outer compartments bulge upwardly to a greater extent than the upper surface of the center compartment. Guide foils having longitudinally extending grooves are disposed below the three compartments at the rear end of the body, the foils associated with the outer two compartments being displaced inwardly relative to their respective compartment axes in the unloaded condition of the sleigh.

Claims

1. A sleigh having an inflatable body which is shaped substantially in the form of a wedge, the interior of said body being subdivided into three longitudinally extending adjacent compartments by two spaced webs which extend longitudinally of said body between the interior upper and lower surfaces of said body, the upper and lower edges of said webs extending substantially parallel to one another, the horizontal spacing between the upper edges of said two webs at said upper surface of said body being less than the horizontal spacing between the lower edges of said webs at said lower surface of said body whereby said webs slant outwardly relative to one another in their downward directions within said body, the upper surfaces of the outer ones of said compartments bulging upwardly to a greater extent than the upper surface of the center compartment when said body is inflated, the forward end of said body having a wedge-shape, the rear end of said body having substantially parallel outer edges, the spacing between the lower edges of said webs at the rear end of said body being substantially equal to the spacing between each of said webs and the adjacent outer edge of said body in the region of said body between said parallel outer edges, and guide means attached to the exterior of the lower surface of said body only in the region of said body between said parallel outer edges, said guide means comprising grooved members located below each of said three compartments respectively, the grooves in said members extending substantially parallel to one another in the longitudinal direction of said body.

2. The inflatable sleigh of claim 1 wherein the upper edges of said webs are slightly higher at the forward end of said body than at the rear end of said body.

3. The inflatable sleigh of claim 1 including hand-holds disposed on both sides of said body at the wedge-shaped forward end of said body.

4. The inflatable sleigh of claim 1 wherein the grooved members below the two outer compartments are offset inwardly relative to their respective compartment axes when said sleigh is in its unloaded condition.
