Modular storage rack for cylindrical loads

Claim 1

In a modular storage rack for cylindrical loads of the type formed by a plurality of corner support post members, a pair of opposed parallel bottom nesting rails mounted on and interconnecting opposed pairs of corner support post members, a pair of square support tubes angularly mounted on and interconnecting opposed pairs of support post members and disposed in cross orientation with respect to the parallel bottom angles, the square support tubes being angularly inclined to present inclined flat support surfaces thereby to carry a cylindrical load therebetween, and further including structural channels to rigidify and strengthen the storage rack the improvement comprising in combination, a plurality of carrying bars, each of said carrying bars being mounted on the top of a corresponding corner support post in parallel orientation with respect to the bottom nesting rails and extending outwardly for a distance with respect to each of the corner support posts, and each of said carrying bars presenting a non-flat nestable surface along the top and bottom exposed surfaces thereof, said top surface of each of said carrying bars having the matingly nesting configuration of a corresponding bottom nesting rail, whereby a series of modular storage racks may be vertically stacked by positioning the bottom nexting rails of one rack on the top surface of the carrying bars of an adjacent rack, such that the carrying bars nest within a corresponding bottom nesting rail, while at the same time presenting a lower surface for said carrying bars which matingly nest with independent carrying hooks to provide a stable and positive engagement of the carrying hook with said carrying bars to facilitate the lifting and transport of said modular storage rack.
