Assembling racks have many advantages such as easy assembly, disassembly and transportation, and easy stocking, so they are indispensable shelves in homes, offices, open-type sales areas, and the like.
Early assembly racks are constructed by assembling a frame with screw parts and installing a shelf on the frame. Disassembly and assembly of such an assembly-type rack requires the use of tools, and the operation is complicated. For this reason, assembly-type racks that can be assembled without the need for tools have emerged, and bamboo-buck racks are typical. Patent Documents 1 to 8 all relate to such a bamboo knot rack.

This bamboo knuckle rack includes a support column having a plurality of horizontal annular grooves and a tapered clamping piece that can be positioned in the annular groove portion. The shelf plate is positioned by tightly binding the outer periphery of the holding piece with the tapered inner diameter of the fitting ring at each corner. Such bamboo section racks have the following two problems that cannot be overcome in use.
1. The fitting ring at the corner of each shelf must be inserted from the upper end of the column, increasing the difficulty of assembly. In particular, when exchanging shelf boards or changing the position of one of the shelf boards, a shelf board that does not need to be moved must be removed, which is very inconvenient in operation.
2. When it is desired to assemble shelves on both sides of the column, adjacent shelves cannot be assembled at the same height and a difference in height is formed, which deteriorates the appearance of the rack after assembly.
