Claim 1
Independent Claim
331 words
A folding portable luggage carrier comprising: a. a horizontal pair of spaced-apart side rails having vertical apertures adjacent to their front and rear ends; b. a horizontal pair of front links pivoted together at their inner ends, said front links having vertical apertures adjacent to their outer ends; c. a horizontal pair of rear links pivoted together at their inner ends, said rear links having vertical apertures adjacent to their outer ends; d. said front link outer end apertures being vertically aligned with said side rail front end apertures, and said rear link outer end apertures being vertically aligned with said side rail rear end apertures; e. a pair of swiveling front casters having their vertical shafts extending upwardly through said aligned front link-side rail apertures, and front retaining means engaging said caster shafts for fixing said caster shafts against downward displacement from said aligned apertures; f. a pair of non-swiveling rear casters having their vertical shafts extending upwardly through said aligned rear link-side rail apertures, and rear retaining means engaging said caster shafts for fixing said caster shafts against downward displacement from said aligned apertures; g. said front links and said rear links folding towards each other so that their pivoted inner ends converge and said side rails draw together in parallel relation to form a folded, portable compact unit having the same overall length as said side rails, said front links and said rear links unfolding away from each other so that their pivoted inner ends diverge and said side rails extend apart in parallel relation to form a rectangular luggage carrying platform; h. the distance from the bottom of said casters to the extreme top of said luggage carrier being less than three times the diameter of said casters; i. tie-down means affixed to said luggage carrier for securing luggage on the luggage carrying platform; and j. pull cord means affixed to said luggage carrier and adapted to be gripped for pulling said luggage carrier across a surface.
