Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
221 words
A multiple container and rack system for use both as a transport and storage medium, the system comprising: a frame assembly, said assembly including a pair of end members, each of said end members including first and second angle corner posts, a rail member fixedly secured at the upper end of each post to maintain said posts from each other the distance of said rail member, and at least one side member, said side member including first and second angle leg members and a rail member fixedly secured to the upper end of said leg members; means for detachably securing each of said side member angle legs nestably within a respective receiving angle corner post; base means includes a flange member for receiving said frame assembly therein and thereby defining a modular unit for receipt of articles to be carried thereby; receiving means on each corner post to permit nestably receipt of one additional modular unit in a stacking manner; restraining means includes at least one inwardly projecting element at each of said flange member upward portions wherein said projecting elements engage the lower angle member of said end member thereby preventing relative vertical displacement thereof; and said restraining means cooperating between said base means and said frame assembly to prevent vertical displacement of said frame assembly from said base means.
Claim 2
Dependent Claim
221 words
A multiple container and rack system for use both as a transport and storage medium, the system comprising: a frame assembly, said assembly including a pair of end members, each of said end members including first and second angle corner posts, a rail member fixedly secured at the upper end of each post to maintain said posts from each other the distance of said rail member, and at least one side member, said side member including first and second angle leg members and a rail member fixedly secured to the upper end of said leg members; means for detachably securing each of said side member angle legs nestably within a respective receiving angle corner post; base means includes a flange member for receiving said frame assembly therein and thereby defining a modular unit for receipt of articles to be carried thereby; receiving means on each corner post to permit nestably receipt of one additional modular unit in a stacking manner; restraining means includes at least one inwardly projecting element at each of said flange member upward portions wherein said projecting elements engage the lower angle member of said end member thereby preventing relative vertical displacement thereof; and said restraining means cooperating between said base means and said frame assembly to prevent vertical displacement of said frame assembly from said base means.
Claim 3
Dependent Claim
37 words
The container and rack system according to claim 1 in which said securing means is formed on each of said corner posts to define a guide channel therewith for slidable receipt of said side angle leg member.
Claim 4
Dependent Claim
62 words
The container and rack system according to claim 2 in which each end member further includes an angle member secured to the lower end of each of said corner posts, said angle member projecting inwardly when said end members and side member are assembled together, said inwardly projecting angle portion providing a support to hold a floor panel for said frame assembly.
Claim 5
Dependent Claim
58 words
The container and rack system according to claim 3 in which said receiving means is an outwardly flared upper portion of said corner posts such that said outwardly flared portion of said angled corner post defines a receiving portion, said frame assembly being complementary dimensioned so as to hold said base means of a stacked modular unit therein.
Claim 6
Dependent Claim
75 words
The container and rack system according to claim 4 in which said side member rail and said end member rail are substantially U-shaped wherein vertical panels may be placed with each side and end member such that the upper edge of each panel is held within said rail U-shaped portion and further including a second side member; said system further a plurality of complementally formed containers mountable within each modular unit for receiving articles therein.
Claim 7
Dependent Claim
68 words
The container and rack system according to claim 4 in which said base means includes a flange member complementally formed to receive said assembled frame assembly therein, said flange having an upward portion and an inwardly projecting lip support for receiving the lower end of each of said corner posts, said flange member having a peripheral shape and size that is receivable within said corner post flared portion.
Claim 8
Dependent Claim
40 words
The container and rack system according to claim 4 in which said base means includes a base plate and upwardly extending flange extending from the perimeter thereof, said base plate and flange receiving the lower end of said corner posts.
Claim 9
Dependent Claim
48 words
The container and rack system according to claim 7 in which said restraining means includes at least one inwardly projecting element at each end of said upwardly extending flange wherein said projecting elements engage said lower angle member of said end member thereby preventing relative vertical displacement thereof.
