In other words, the vertical bolt 19b facing upward is fitted from the lower portion of the connecting portion 12c of the vertical frame 12, and the fixing nut 19c is fitted and fixed into this vertical bolt 19b. FIG. 2 shows the two or more shelves 13a, 13b (13c, 13d) mounted on each of the vertical frames 12 at the four corners in a collapsed state.

[0017] The above-mentioned two or more tiered shelves 13a, 13b (13c, 13d) are shown in their respective stored states in Figure 3(A), spread out in the width direction in Figure 3(B), with drawers 14a, 14b pulled out from beneath the lower shelf 13b of the two or more tiered shelves 13a, 13b in Figure 3(C), and with the two or more tiered shelves 13a, 13b and shelves 13c, 13d spread out in the width direction and with the drawers 14a, 14b pulled out from beneath the lower shelf 13b in Figure 3(D).

[0018] That is, Figure 3 (A) shows a state in which the expandable horizontal bars 15a, 15b and horizontal bars 15c, 15d are arranged between a pair of vertical frames 12a and 12b, and two or more shelves 13a, 13b (13c, 13d) are attached via locking hooks 16a, 16b (see Figure 4) provided at the front and rear ends thereof via a pair of the expandable horizontal bars (not shown) arranged vertically. FIG. 3(B) shows the state in which the shelves 13a, 13b (13c, 13d) having two or more upper and lower shelves are each spread out in the width direction via extendable horizontal bars (15a, 15b, 15c, 15d, see FIG. 1). FIG. 3(C) shows a state in which the drawer plates 14a, 14b below the lower shelf plate 13b are pulled out from the state shown in FIG. 3(A). Finally, FIG. 3(D) shows the state in which the two or more shelves 13a, 13b (13c, 13d) are each spread out in the width direction, and furthermore, the drawers 14a, 14b below the lower shelf 13b are pulled out. Furthermore, the drawer plates 14a, 14b below the lower shelf plate 13b can be smoothly pulled out via a pair of guide rails 13e arranged in the width direction along the space between the pair of vertical frames 12a and 12b (see Figures 1 and 2, respectively).

[0019] FIG. 4 is a schematic plan view and a schematic side view of the state in which the shelves 13a, 13b (13c, 13d) each having two or more upper and lower tiers are spread out in the width direction, and each shelf can be spread out in the width direction by sliding it using the locking hooks 16a, 16b provided at both the front and rear ends.

[0020] Next, the modified example in Figures 5(A) and (B) shows that at least the vertical frames 12 at the four corners are made up of a combination of a pair of rectangular frames 31 on the left and right, and the vertical frame 12 portion of the pair of rectangular frames 31 on the left and right is constructed of steel material 32 with an L-shaped cross section, and a predetermined number of screw holes 33 are formed in sequence in the vertical direction in the vertical frames 12 at the four corners that make up the pair of rectangular frames 31 on the left and right. Horizontal bars 34, 35 are disposed vertically between the vertical frames 12 on the side surfaces of the four corners, and an appropriate number of hanging hooks 36 equipped with J-shaped engaging portions 37 are hung from the upper horizontal bar 34 that protrudes slightly outward, as shown in the attached drawing (within the dotted-chain circle). In Fig. 5(B), 38 is a U-shaped engaging hook provided at the upper end of the engaging portion 37. FIG. 5(A) is a front view of the modified example, and FIG. 5(B) is a perspective view thereof seen from above. The height of the U-shaped retaining frame 17 spanning the vertical frames 12 and the height of the multi-tiered shelves 13a, 13b attached to the U-shaped retaining frame 17 can be adjusted by adjusting the mounting position of the screw holes 33. In Figures 5(A) and (B), the rectangular frame 31 can be suitably made of an L-shaped cross-section steel material 32 or hard wood, etc., and by using the rectangular frame 31, it is possible to obtain a vertical frame 12 that is easy to manufacture and has excellent strength.

[0021] As shown in FIG. 1, in the multi-tier rack 10 having vertical frames (12) at at least the four corners and multiple shelves 13a, 13b (13c, 13d) fixed between the vertical frames (12), the shelves 13a, 13b are configured in two or more tiers and are supported via each pair of driven, extendable second horizontal bars 15c, 15d and are extendable in the width direction. Furthermore, the multiple shelves 13a, 13b (13c, 13d) can be extended and fixed via upper and lower connected, extendable horizontal bars 15a, 15b fixed between the vertical frames (12a, 12b). Furthermore, drawer panels 14a, 14b that can be pulled out forward are provided below the lower shelf panel 13b, providing the extremely useful function of allowing documents and other items to be stored as appropriate, while also making it possible to provide a multi-tier rack with extremely inexpensive multiple shelves.

[0022] The vertical frames 12 at the four corners and the connectable, expandable horizontal bar 15a may be made of aluminum or other metals or FRP, and the multi-level shelves 13a, 13b (13c, 13d) may be made of metal or hard wood. In addition, the drawer plates 14a, 14b arranged below the two or more shelves 13a, 13b (13c, 13d) can be pulled out forward to make wider use of the multi-tier rack 11, making it extremely user-friendly and expanding the range of applications.

[0023] Incidentally, Figure 6 is a schematic side view showing a case in which shelf boards 14a, 14b can be attached to slide guides 18 that are movably held within a U-shaped holding frame 17 on both sides of the drawer boards 14a, 14b, and the drawer boards 14a, 14b can be pulled out forward via the slide guides 18. In addition, in FIG. 7, bolts 21 and nuts 22 for attaching the U-shaped holding frame 17 and the slide guide 18 movably held therein to the vertical frame 12 are shown. Furthermore, Figure 8 shows a case in which drawer plates 14a, 14b are attached to a slide guide 18 that is movably held within a U-shaped holding frame 17, and the drawer plates 14a, 14b can be pulled out in the direction of the arrow via the slide guide 18.

[0024] FIG. 9 shows a reference embodiment of a rack with a drawer shelf according to the present invention, and is a schematic perspective view showing an overall view of a rack 41 with one shelf . In any case, it is a rack equipped with shelves that can be extended in the width direction, and because it is equipped with shelves that can be extended in the width direction, it is possible to provide a rack that is extremely easy to use.
