BACKGROUND OF THE INVENTION
There is a need for shelving systems that are quickly and easily assembled. One oE the best ways to facilitate the assembly i5 to use pieces that can be assembled without any tools. The advantages o such construction usually also apply to the disassembly oE the shelving, and to the rearrangemen-t of the height and placements of the various shelves within the system.
One oE the difficulties in making a set of shelves without tools is to fit and interlock the pieces -tightly enough that the shelving system is suEficiently rigid to s-tand securely and to support whatever objects are supposed to be placed on the shelves.
Another problem in making such a set of shelves is to do it with a minimal number oE pieces and steps of construction.

GENERAL DESCRIPTION OF THE :[NVENTION
The shelving system of this inv~n-tion is comprised of a number of typical rectangular shelves and a special modular vertical post and bracke~ construction.
The vertical struc~ure pieces are joined to the shelves by means of the brackets. The shelves are held in a vertical arrangement by means of the brackets being joined to the ver-tical structure pieces~ There are two kinds of vertical structure pieces: posts and end plugs.
The top and bottom flange of each bracket has a female threaded hole. Each of the post pieces has a male threaded top and bottom. The post can thus be thread~d into one of the bracket holes. The bracket can be made of plastic, wood, metal, or any other sui-table material. The posts can likewise be made of plastic, wood, metal, or any other suitable material. The other component, a male threaded plug, can be used to finish off the bracket at the top of each of the corners of the top shelf of the assembled structure.
The assembly of the shelves is done as follows:
Step 1. The assembly of a typical shelving unit is begun by sliding a close-fitting bracke-t onto the Eirst (bottom) shelf board at or near eac'n corner of the shelf.
Step 2. The brackets are held firmly in place by screwing a post connector into the top of each bracket and tightening down until the bottom oE the post connector is in firm contact with the shelf board.
Step 3. Four new brackets are -then screwed onto -the top end of -the four upright post connectors, the assembler taking care -that the threaded ends o f the post do not e~tend beyond the inside face of the bracket. The brackets should be twisted to face inward, in an orientation such that they can receive and grip a second shelf. At this time the assembler may choose to insert a foo-t plug in the bottom of each bracket to slightly elevate -the unit, or to adjust the foot plugs to level the unit if it is on an uneven floor surface.
Step 4 a The next level of shelf board is slid into the brackets from the fron-t or end, depending on the location and orientation of the brackets.
Step 5: Continue to repeat steps 2, 3 and 4 until the desired number of shelves or overall unit height is achieved.
Step 6: Insert a short threaded top securing plug into -top of each topmost bracket connector and tighten down firmly onto the top of the shelf board.
No modifications are necessary to the shelf board~ or connectors, and the system may be assembled, revised or disassembled without damage to any components.
Structural strength is maintained by transferring the accumulated multiple shelf loads vertically downward through -the posts which are situated within the outline oE the shelves. There are no cantilevered or angled forces in this post over bracket structure.
Any type of shelf board with a thickness matching the size 535~
of the side bracke-t connec-tor can be used to assemble a Eull shelving system. The total maximum load is limited mainly to the shelE board beam streng-th and the compressive strength of the connector posts.
The shelving unit can be made ~uite low, for use as a table top~ and in fact the unit can be made stable with only one shelf, the supporting posts extending -to the floor.
The post connectors can be made in sets to match the desired heigh-t between any -two shelves in the shelving unit. The sets of posts for each shelE may be mixed in any combination in -the same sys-tem for a variety of heights between shelves.
The post components and the shelves can be oE any size or material within the structural limits of those materials.
The post components can be molded or machined into the correct form for -the system. The brackets can be round or square on their outer surfaces, edges, or corners.
E'or long shelves, addi-tional brackets and posts could be placed in the middle of the shelf for increased support.
A subsidiary option would be to have rubber feet on -the foot plug components -to reduce skidding by the shelving unit on a smooth 100r.
This invention could be sold as a kit, for assembly by the re-tail purchaser. It would also be suitable for sale from mix-and-match bins con-taining a variety oE styles, shapes and sizes of shelves and vertical structure pieces. The 3~
invention provldes an easy rneans of construction of both utility and decorative shelving for a wide variety of purposes.
