摘要:
A weatherproof document case with a table and a cover. The table has a table top, a table side and table lip, the table lip lower than the table top. The cover has a cover top, a cover side and a cover lip, with the cover lip lower than the cover top. The cover is coupled to the table such that when the cover is in a closed position, the cover lip contacts the table lip and such that when the cover is in the open position blueprints can be placed on or removed from the table top. A user simply raises the cover to place the blueprints beneath the transparent cover to protect them from the elements.

One type of modular cabinet frame structure is primarily made up of two square cross sectional tubes with three connectors; the surfaces of the two tubes are equipped with inset joining grooves to meet the needs of different types of arrangements; the interior of the tubes are equipped with projecting strengthening ribs for upright structures that cause the center of the hollow interior of the tubes to overlap with the center of the tubes. The connectors consist of square units upon the surface of which are mounted three, four or five tenon posts that can be inserted in the tubes described above and form different types of connections in various directions.

A connector for cross-sectionally square, rectangular, hexagonal or other shaped tubes, including a solid cube-shaped block body having tapered arm members extending outwardly from its square sides; each arm having a spiral pipe screw thread therearound intercepted by elongated flutes so that the arm is cross-sectionally Greek cross-shaped with outwardly rib portions between the flutes, so as to be slidably fitted into a square or rectangular tube end or into the end of a hexagonal or other shaped tube with a square insert with the ribs being received in the corners of the square or rectangular tube or of the square insert whereby subsequent rotation of the tube causes the screw thread on the outer side of the ribs to cut an engaging thread on an inner side of the tube, or on the inner side of the square insert.

A plurality of side rails, cross rails, side and corner legs are prefabricated from a square, tubular, 12 gauge steel material. Separable side and corner connecting members formed of substantially the same tubular steel material include projecting arms and bridging members that are inserted into the open ends of the side rails, cross rails, side and corner members to assemble the table. The connections are secured by bolting the structural frame members to the connecting members. Tubular rectangular side tracks are secured to the upper surface of the side rails in certain installations to provided support for wheeled carriages that are adapted to move longitudinally of the table. The side connectors and corner connectors are, in general, fabricated identically, then utilized in the assembly by slightly different orientation, hole patterns, and the use of the different bridging members.

A corner fitting is provided in which from two to six tubes may be secured together in right angular relation. A square block forms the corner. By drilling a hole in the center of any surface of the block, an expandable rectangular fitting may be secured against this surface. By turning the tube ninety degrees in either direction, the expandable fitting will expand and securely lock the end of the tube to the block.

The disclosure concerns a rack for displaying articles and comprising an assembly of horizontally and vertically oriented profiled bars, each provided with longitudinal grooves within which displaceable clamping elements can be clamped. These clamping elements may be rack inserts or serve as supports for such inserts. Grooves of adjacent vertical bars open toward each other for receiving wall-like elements. Also, other grooves of the vertical bars open into the interior area of the rack. Profiled bars which meet at corners are connected to each other by plug elements which plug into the bars and are hidden by the bars.
