COLUMN STRUCTURE

PROBLEM TO BE SOLVED: To provide a column structure for improving the convenience of storage and conveyance by detaching a column from a top plate or bottom plate of a table, a display shelf or the like at the time of non-use. SOLUTION: In the column structure for fitting a turning part to a fixing part 610, a base 61 configuring the fixing part is fixed to the top plate or/and the bottom plate, a short cylindrical fitting projection projects on the base, an opening groove 64 is perforated on the bottom surface 62 of the fitting projection, and helical surfaces S2 which are gently inclined respectively are formed on both sides of the opening groove. The turning part is attached to the end part of the column, a skid is bridged in the diameter direction at the almost end part of the column, and a T-shaped lock bar is raised at the almost center of the skid. The fitting projection of the fixing part is inserted and fitted to the inner periphery of the column in the turning part, the locking bar of the T-shaped lock bar is inserted and fitted to the opening groove of the bottom surface, and the column is turned around the axis. Thus, the turning part is fixed to the fixing part while the locking bar is tightened to the helical surface. COPYRIGHT: (C)2010,JPO&INPIT
