At this time, each The balls 49 of the locking device 46 are engaged with the circular holes 45 of the telescopic struts 41-44. child Due to the engagement of the ball 49 with the circular hole 45, each folding of each of the telescopic columns 41 to 44 is performed. The state of extension from the struts 31 to 34 is maintained.

[0019] As shown in phantom lines in FIG. When the panel 60 is transported, the panel 60 is placed on the base 11 with the higher height direction facing up and down. and is placed against one of the beam members 51. In this state, the beam member 51 has sufficient height, so even the relatively tall panel 60 can be effectively supported. You can get it. By transporting the panel 60 in an upright state in this way, When the elevator is used during transportation, the panel 60 is placed on the trolley 10. It can be carried into the elevator.

[0020] When the trolley 10 for transporting long objects is moved, the operator uses an appropriate telescopic support 41. The upper part of ~44 or the panel 60 is held and runs parallel to the beam members 51 and 52. be done. At this time, since the beam members 51 and 52 are installed in the front-rear direction, and the beam members 51 and 52 are Since the front can be seen along the panel 60 leaning against the member 51, the direction of travel can be determined. Easy to decide. During this running, the third and fourth wheels 14 and 15 are configured by casters. Because of this, it can curve smoothly. At this time, The third and fourth wheels 14 and 15 are arranged to protrude outward from the base 11.

[0021] Note that the work of loading and unloading the panels 60 onto the trolley 10 for transporting long objects is carried out using the first beam member. 51 and the second beam member 52 from the front and back directions, or from the top and bottom directions. You can also run it from When loading and unloading from the top and bottom, each telescopic column 41 to 44 It can also be executed in a shortened state.

[0022] As shown in FIG. 7, the cart 10 for transporting long objects is folded when not in use. It is stored in the same state. First, each telescopic support 41-44 is connected to each folding support 31-34. It is inserted within and abbreviated. At this time, if you push the telescopic column strongly from above, the locking device will open. The ball 49 of 46 is pushed against the opening edge of the circular hole 45 and is pushed by the elastic force of the spring 50. Since the ball 49 is pushed into the main body 47 against the resistance, the engagement between the ball 49 and the circular hole 45 is one-sided. It is canceled by touch operation (see Figure 4).

[0023] Next, each folding column 31-34 is slightly separated from each fixed column 21-24. By being pulled out, the stopper pin 36 is pulled out from the notch 26. In this state, when each of the folding columns 31 to 34 is tilted inward of the base 11, the 6, each folding column 31-34 is connected to a guide pin in the elongated hole 25. 35, and is inserted into the inner relief part 27 and laid down. That will happen.

[0024] When the folding columns 31 to 34 on both sides are folded, the springs 55 and 56 are pulled. The movable side hooks 57 and 58 of the springs 55 and 56 were folded. They are engaged with fixed side hooks 53 and 54 protruding from the beam members 51 and 52 of the pillar, respectively. will be stopped. In this state, the springs 55 and 56 support the beam members 51 and 52 on the base 11. Since the struts are tied in a tight state by pulling in the direction, the struts do not move loosely and are easy to handle. This makes it easy to move and store.

[0025] Furthermore, in the case where a plurality of long object conveyance trolleys 10 according to the above configuration are prepared, The long object conveying carts 10, 10 are stacked one on top of the other and stored. vinegar In other words, as described above, the long object conveyance trolley 1 is placed on the lower side in a folded state. For transporting long objects, which are also folded and arranged on the upper side of each of the fixed columns 21 to 24 of 0 The holding frames 61 to 64 of the truck 10 are fitted into each other. This mating allows the length of the top and bottom to be Since the carts 10 and 10 for transporting long objects are reliably positioned with respect to each other, it is possible to transport multiple long objects. Even when the transportation carts 10 are stacked, the cargo does not collapse. However, Therefore, a large number of carts 10 for transporting long objects can be safely stored without taking up floor space. can be done.

[0026] By the way, to assemble each support, please use the reverse method of folding as described above. That's fine.

[0027] It should be noted that the present invention is not limited to the above-described embodiments, and does not depart from the gist thereof. It goes without saying that various changes can be made within the range.

[0028] For example, the relief portions 27 of each of the fixed columns 21 to 24 are limited to being provided only on the inner side wall. Alternatively, as shown in FIG. 8, it may be provided on the outer side wall. There is also leakage on the outside side wall. If the peeling section 27 is opened, each folding column 31 to 34 is also laid down on the outside. can be done.

[0029] The locking device 46 includes a circular hole 45, a ball 49, and a stopper as in the previous embodiment. As shown in FIG. A configuration in which a part of the leaf spring 50A engages with an engagement recess such as the circular hole 45 is used. You may.
