PROBLEM TO BE SOLVED: To provide a hollow pipe-type knock-down shelf capable of easily retaining horizontal accuracy of shelf brackets and preventing displacement of the shelf brackets caused by weight and vibration of a placed object.SOLUTION: The hollow pipe-type knock-down shelf includes: four pipe supports 1a, 1b, 1c and 1d vertically installed at respective vertices P, Q, R, and S of a rectangle on a horizontal surface; a shelf bracket 2a disposed between two facing pipe supports 1a and 1b; and a shelf bracket 2b disposed between the pipe supports 1c and 1d. The pipe supports 1a, 1b, 1c, and 1d include a plurality of holes 1e provided on one axial-directional straight lines at prescribed intervals. The shelf brackets 2a and 2b include projections 2c and 2d at both left/right ends T and U respectively for being fitted in pipe supports and fixing the shelf brackets.SELECTED DRAWING: Figure 1 |
