Joiner support

Claim 1

A joiner support for joining end-to-end two horizontal shelves which have vertically spaced, round, upper and lower end rods, said joiner support comprising: front and back shells, each having a vertically disposed plate, top and bottom horizontal peripheral lips and vertical peripheral lips at opposite ends of the plate, said top, bottom and end lips on each shell projecting inwardly the same amount substantially perpendicular to the plate and abutting against the corresponding lips on the other shell to define a chamber between the two shells; each of said shells having aligned upper and lower semi-circular recesses in its opposite end lips, the upper recesses being disposed just below and substantially tangent to a projection of the respective top lip at the latter''s inner edge, the lower recesses being disposed just above and substantially tangent to a projection of the respective bottom lip at the latter''s inner edge, each of said recesses being spaced inward from the respective plate, the upper semi-circular recesses in the two shells registering with each other at both end lips to define respective upper circular openings for snugly receiving the upper end rods of the shelves to be joined, the lower semicircular recesses in the two shells registering with each other at both end lips to define respective lower circular openings for snugly receiving the lower end rods of the shelves to be joined; each shell having an upper, horizontal partition projecting inward from the plate the same amount as the peripheral lips thereon at a location laterally inward from the end lips and spaced below the top lip by substantially the diameter of said upper semi-circular recesses in the end lips, so that said upper end rOds of the shelves to be joined are both snugly engaged from above and below by said top lip and said upper partition in laterally spaced relationship to their snug engagement in the upper circular openings at the abutting end lips on the shells; each shell having a lower horizontal partition projecting inward from the plate the same amount as said peripheral lips thereon at a location laterally inward from the end lips and spaced above the bottom lip by substantially the diameter of said lower semi-circular recesses in the end lips, so that said lower end rods of the shelves to be joined are both snugly engaged from above and below by said lower partition and said bottom lip in laterally spaced relationship to their snug engagement at the lower circular openings at the abutting end lips on the shells; and means spaced from said recesses and said partitions for releasably clamping said front and back shells together with the peripheral lips of one abutting against the peripheral lips of the other and with the upper and lower partitions of one abutting respectively against the upper and lower partitions of the other.
