The auxiliary pedestal 123 may be formed on the pair of fifth frames 132 instead of the pair of third frames 106. That is, the auxiliary pedestal 123 may be formed on the uppermost pair of frames.

FIG. 9 is a view showing a use state of a display stand combination cart according to another embodiment of the present invention.

9 (a) shows a state in which the baskets 50 are accommodated in the pair of first frames 102 to the pair of fifth frames 132. Next, Fig. 9 (b) shows a state in which the 2-1 frame 104-1 to the 5-1th frame 132-1 are unfolded and arranged side by side on one side of the 1-1 frame 102-1 State. Next, FIG. 9 (c) shows a state in which the 2-2 frame 104-2 to the 5-2nd frame 132-2 are spread and arranged on the other side of the 1-2 frame 102-1 State. Next, FIG. 9D shows a state in which the height of the second support portion 118-2 is lowered. Next, FIG. 9E shows a state in which the second support portion 118-2 is rotated and then pushed into the lower portion of the pair of first frames 102. In FIG. 9 (d) and 9 (e) will be described later in detail with reference to FIGS. 10 to 12. FIG.

In the disclosed embodiment, it is possible to lower the height of the second support portion 118-2, as shown in Fig. 10, with the frames in which the basket 50 is received laid out in a line. The second support portion 118-2 may be provided in the form of a multi-stage rod. That is, the second support portion 118-2 may be provided so that one rod is inserted into the rod provided at the lower portion of the rod to adjust its height. The second support portion 118-2 may be provided with a button (not shown) for adjusting the height of the second support portion 118-2. For example, the height of the second support portion 118-2 may be adjusted while the button (not shown) is pressed.

For example, in a state where the height of the second support portion 1118-2 is adjusted as low as possible, the second support portion 118-2 is unlocked by unlocking the first lock portion 155, as shown in Fig. 11 It can be rotated. That is, the second support portion 118-2 can be rotated clockwise to place the second support portion 118-2 horizontally with the ground.

Next, as shown in Fig. 12, the second locking portion 157 can be unlocked and the second supporting portion 118-2 can be pushed into the lower portion of the pair of first frames 102. As shown in Fig. That is, when the second locking portion 157 is unlocked, the second supporting portion 118-2 is drawn out through the second vertical tube 153a, 1 frame 102, as shown in Fig.

According to the disclosed embodiment, the baskets 50 can be moved while accommodating the plurality of baskets 50 through the frames stacked on top of each other. In addition, since the frames stacked on top of each other are laid out in a line, the basket 50 can be used as a shelf in a state of being housed in the frame. Accordingly, Time and time can be reduced. In addition, since the second support portion 118-2 can be pushed to the lower portion of the frame in a state in which the second support portion 118-2 is folded (that is, the height is minimized), the volume can be minimized in the shelf state, .
