<p>PROBLEM TO BE SOLVED: To provide a folding tray shelf with a mechanism that can be folded simply and easily, does not take up space during storage, and is movable independently.SOLUTION: Side plates 3 comprise upper shelves 4, lower shelves 5 and hooks 7, and can configure a side surface and one side of the shelf for mounting a tray 1. Pole shafts 6 are inserted in the vertical direction of four corners of the upper shelves 4 and the lower shelves 5, respectively, and the sides with projected flanges of the upper shelves 4 and the lower shelve 5 of right-and-left side plates 3 are connected oppositely via bearing lids 10 and connecting rods 8, and thereby a folding tray shelf is formed. The side plates 3 and the connecting rods 8 are rotatable centering on the pole shafts 6, and can be changed into a parallelogram. Accordingly, the folding tray shelf becomes foldable by the structure that can be changed into an elongated rhombus until the flange tips of the upper shelves 4 are brought into contact with the flange tips of the lower shelves 5 of the opposite side plates 3.</p> |
