Abstract
Abstract A toboggan comprising several sections which may be folded for transportation and storage. The toboggan includes an improved coupling between the sections which permits the toboggan to be folded and take up no more space than if the toboggan were completely disassembled for storage. Furthermore, no adjustments are necessary upon unfolding the toboggan for use.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
175 words
A hinged sectional toboggan having at least two longitudinally spaced sections, each section having a forward and rearward end, said sections being hingedly connected along adjacent edges, comprising: a forward section having a plurality of laterally spaced integral bosses projecting rearwardly from the rearward end thereof, a rearward section having a plurality of laterally spaced integral bosses projecting forwardly from the forward end thereof, a transverse link member between said longitudinally spaced toboggan sections having opposed spaced forwardly and rearwardly projecting integral bosses extending perpendicular to its length, said link bosses interdigitated between said section bosses, a first hinge pin pivotally interconnecting the rearwardly projecting bosses of said forward section and said forwardly projecting bosses of said link member and a second hinge pin, parallel to said first hinge pin pivotally interconnecting the forwardly projecting bosses of said rearward section and said rearwardly projecting bosses of said link member, said hinge pins providing two spaced, parallel pivot axes, whereby each of said toboggan sections may be folded against either opposed face of the adjacent section.
Claim 2
Dependent Claim
175 words
A hinged sectional toboggan having at least two longitudinally spaced sections, each section having a forward and rearward end, said sections being hingedly connected along adjacent edges, comprising: a forward section having a plurality of laterally spaced integral bosses projecting rearwardly from the rearward end thereof, a rearward section having a plurality of laterally spaced integral bosses projecting forwardly from the forward end thereof, a transverse link member between said longitudinally spaced toboggan sections having opposed spaced forwardly and rearwardly projecting integral bosses extending perpendicular to its length, said link bosses interdigitated between said section bosses, a first hinge pin pivotally interconnecting the rearwardly projecting bosses of said forward section and said forwardly projecting bosses of said link member and a second hinge pin, parallel to said first hinge pin pivotally interconnecting the forwardly projecting bosses of said rearward section and said rearwardly projecting bosses of said link member, said hinge pins providing two spaced, parallel pivot axes, whereby each of said toboggan sections may be folded against either opposed face of the adjacent section.
Claim 3
Dependent Claim
27 words
The sectional toboggan defined in claim 1 characterized in that each of said toboggan sections includes an upwardly projecting continuous peripheral flange for receipt of a pad.
Claim 4
Dependent Claim
45 words
The sectional toboggan defined in claim 2, characterized in that each of said sections include a plurality of integral upright ribs joined to said peripheral flange and a bottom wall of said sections, said upright ribs including aligned apertures receiving a rope spanning said ribs.
Claim 5
Dependent Claim
21 words
The sectional toboggan defined in claim 1, characterized in that said toboggan sections are formed of a relatively rigid, self-supporting thermoplastic.
