More specifically, the screw B3 is screwed to a plurality of nuts N2 (FIG. 3) held by the second rail portion 66 of the frame 6, and the screw B4 is inserted through the mounting plate 51 and the rib 10 and above the rib 10. And is screwed to a nut (not shown).

  A method for handling the transport cart 1 configured as described above will be described. First, during normal use, as shown in FIG. 1, a load is placed on the cart body 2 with the support 4 held by each support holding member 3, and the support 4 is gripped (or pushed). What is necessary is just to move the trolley | bogie 1 to a predetermined position. By holding the column 4 in this manner on the column holding member 2, the column 4 functions as a guide even when a long baggage such as a bar is placed on the cart body 2, and load collapse is prevented.

  On the other hand, when the transport cart 1 is not used, as shown in FIGS. 5 and 6, the column 4 is detached from the column holding member 3, and the removed column 4 is attached to the side surface 21 (more specifically, the cart body 2). Of the side surface 21 of the carriage main body 2, the column holding member 3 and the left and right side surfaces 21a, 21b, to which the reinforcing plate 9 is attached, are inserted into and accommodated in the column accommodation recesses 22. At this time, since the partition piece 92 is provided on the inner surface of the reinforcing plate 9, the user may insert the support column 4 into the support column holding recess 22 until the tip of the support column 4 comes into contact with the partition piece 92. And when the support | pillar 4 is accommodated in this way, the support | pillar 4 will be hold | maintained along the circumferential direction of the side surface 21 of the trolley | bogie main body 4, and the support | pillar 4 will be the support | pillar holding recessed part by the flat plate member 71 and the reinforcement board 9 of the support | pillar holding member 3. It is prevented from falling out of 22. That is, the support column holding member 71 and the reinforcing plate 9 function as a means for preventing the support column 4 from falling off.

  Thus, in the state which removed the support | pillar 4, the several conveyance trolleys 1 can be stacked and stored compactly. In this case, as shown in FIG. 7, the lower end portion of the leg member 72 of the upper carriage 1 is abutted against the upper end of the support member 8 of the lower carriage 1. Since the lower opening of the leg member 72 has a larger cross section than the cross section of the support member 8, the upper end portion of the support member 8 of the lower transport carriage 1 is connected to the leg member 72 of the lower transport carriage 1. The transport cart 1 on the upper stage side is supported so as to be inserted from below, and thereby the lateral displacement of the transport cart 1 stacked is prevented. Further, as described above, the height dimension D3 of the column holding member 3 when the support member 8 is in the lower position is set to be larger than the distance D4 from the lower end (grounding surface) of the caster 5 to the upper surface of the cart body 2. Therefore, the caster 5 of the transport cart 1 on the upper stage is kept floating from the cart body 2 of the transport cart 1 on the lower stage, and the lower caster is brought into contact with the caster 5 of the transport cart 1 on the upper stage. It is possible to prevent the top plate 20 of the carriage 1 from becoming dirty.

  Further, when a load larger than the width of the transport cart 1 is placed, the support cart 8 is lifted and folded from the state shown in FIG. Can be in a fully flat state.

  On the other hand, in order to return from the state shown in FIG. 8 to the state shown in FIG. 1, first, the support member 8 is raised from the tilted state to the standing state, and then the lower portion of the support member 8 is inserted into the leg member 72. Return to. Then, the support 4 is taken out from the support housing recess 22 and the support member 8 is inserted into the support 4 so that the lower portion of the support 4 is fitted on the support member 8.

  As described above, according to this embodiment, the support column 4 removed from the support column holding member 3 can be stored in the support column recess 22, so that the removed support column 4 is lost or the support column 4 is difficult to place. Can be avoided. Further, since the bottom surface 64a of the support housing recess 22 extends obliquely downward toward the outside, for example, even if rainwater enters the support housing recess 22 of the transport carriage 1 left outdoors, It flows down along the bottom face 64a without accumulating in the accommodation recessed part 22, and can drain well.

  Furthermore, since the position of the column holding member 3 can be adjusted along the first rail portion 63, a relatively short bar shape can be obtained by adjusting the interval of the column holding member 3 according to the length of the load to be placed. Even when a load is placed, the collapse of the load can be prevented. Further, for example, as shown in FIG. 7, the transport cart 1 and the fixture 100 can be stacked by adjusting the mounting location of the support column holding member 3 according to the existing fixture 100.

  Since the caster 5 is attached by screwing the screw B3 to the nut N2 held by the second rail portion 66 provided on the lower surface of the frame 6, the mounting position of the screw B3 changes depending on the dimensions of the caster 5 used. However, since the mounting position of the screw B3 can be adjusted along the second rail portion 66, the caster 5 having various dimensions can be easily accommodated.

  In addition, the conveyance trolley | bogie 1 comprised in this way can also be used in combination with the upper stage member 200 shown, for example in FIG. The upper member 200 includes a mounting table 201 and a cylindrical connecting tool 202 suspended from the four corners of the mounting table 201. By inserting the support column 4 of the transporting carriage 1 through each connecting tool 202, the transporting car 1 can be used as a two-stage transport cart.

  As mentioned above, although the conveyance trolley | bogie which concerns on embodiment of this invention was demonstrated with reference to attached drawing, this invention is not limited to this embodiment, Various deformation | transformation thru | or correction | amendment are possible without deviating from the scope of the present invention. It is.

  For example, in the above-described embodiment, the support body 3 and the reinforcing plate 9 are attached to the left and right side surfaces 21a and 21b extending in the longitudinal direction (left and right direction in FIG. 2) in the cart body 2 formed in a rectangular shape in plan view. Although the example has been described, in addition to (or instead of) the left and right side surfaces 21a and 21b, the column holding member 3 and / or the reinforcing plate 9 are provided on the front side surface 21c and / or the rear side surface 21d extending in the short direction of the carriage body 2. You may make it attach.

  Moreover, in the said embodiment, although the upper member 72b and the supporting member 8 of the leg member 72 were made into the rectangular tube shape, it does not necessarily need to be a rectangular tube shape, and a cylindrical shape etc. may be sufficient.
