Since the

wheels

35A and 35B are rotatably provided, the operating rod 31 of the operating tool 30 can not maintain the standing state if there is no support. However, as shown in FIG. 4 and the like, the arm portion 36 contacts the floor surface FL to restrict the tilting of the operating rod 31, whereby the operating rod 31 is maintained in the upright state in a slightly inclined state.

Next, the connecting operation of the carriage body 10 and the operation tool 30 will be described.
In order to connect the bogie main body 10 and the operation tool 30, first, as shown in FIG. 4, the connection portion 33 of the lifter portion 32 of the operation tool 30 is positioned below the connected portion 15 of the loading portion 10. The attitude (tilt) of the operating rod 31 and the position of the operating tool 30 are adjusted.
Specifically, as shown in FIG. 5A, the operation tool 30 is made to approach the loading section 11 installed on the floor surface FL. At this time, the inclination of the operating rod 31 is adjusted so that the projecting portion 34 of the connecting portion 33 is positioned lower than the lower end surface 15 of the engaged portion 15. As shown in FIG. 4, when the operating rod 31 is supported by the wheel 35 and the arm 36, the projecting portion 34 of the connecting portion 33 is disposed below the lower end surface 15 of the engaged portion 15. It is designed as.

Next, as shown in FIG. 5B, the operation tool 30 is brought close to the carriage main body 10, and the projecting portion 34 of the connecting portion 33 is operated to be directly below the through hole 15a of the engaged portion 15. Then, as shown in FIG. 5C, the operating rod 31 is inclined in the tilting direction A1. The tilting direction A1 is opposite to the inclined direction of the operating rod 31 shown in FIGS. 4 and 5A. When the operating rod 31 is inclined in the tilting direction A1, the position of the projecting portion 34 of the connecting portion 33 moves upward, and a part of the projecting portion 34 gets into the through hole 15 a of the engaged portion 15 and the projecting portion 34 Is in contact with the inner peripheral surface of the through hole 15 a and the upper end surface 33 a of the connecting portion 33 is in contact with the lower end surface 15 b of the engaged portion 15. That is, the connecting portion 33 is engaged with the engaged portion 15.

When the operating rod 31 is inclined in the tilting direction A1, as shown in FIG. 5D, the tilting moment acting on the operating rod portion 31 by the operation of the operator locks the upper end surface 33a of the connecting portion 33 with the wheel 37 as a fulcrum It acts as a force that pushes up the lower end surface 15b of the coupled portion 15 upward. At the same time, the wheel 35 as a fulcrum moves in the direction B1 toward the lower position of the through hole 15a. By this “wrinkle action”, the lower end surface 12 b of the support portion 12 of the carriage body 10 rises from the floor surface FL, and a slight gap is formed between the floor surface FL and the lower end surface 12 b of the support portion 12.
As the operating rod 31 is further inclined in the tilting direction A1, as shown in FIG. 5E, the wheel 35 further approaches the lower position of the through hole 15a, and the load of the loading platform 11 supported by the wheel 35 increases. The moment in the direction opposite to the tilting direction A1 acting on the operating rod 31 also decreases sharply, and the operator hardly feels any reaction force from the operating rod 31.
As shown in FIG. 5F, when the wheel 35 reaches the lower position of the through hole 15a, the lower end surface 15b of the connected portion 15 is in full contact with the upper end surface 33a of the connecting portion 33, and the wheel 35 cooperates with the wheel 13. Work to support the load of the loading platform 11. As a result, a moment in the reverse direction to the tilting direction A1 does not act on the operating rod 31. At this time, the arm portion 26 abuts on the bottom surface 11 b of the loading portion 11, and the further inclination of the operating rod 31 in the tilting direction A1 is restricted. As a result, the dolly 1 is in the state shown in FIG. 1A. In this state, the connecting portion 33 is rotatable with respect to the connected portion 15. In addition, although a slight gap is formed between the lower end surface 12b of the support portion 12 and the floor surface FL, and the loading portion 11 is slightly inclined, this inclination is an inclination that does not affect the loaded luggage. is there.

In the carriage 1 in which the carriage body 10 and the manipulation tool 30 are connected to each other, as shown in FIG. 6A, the manipulation tool is maintained in the direction along the longitudinal direction L1, L2 of the carriage body 10 By pushing or pulling, it can be advanced or retracted straight.
In order to change the moving direction of the carriage 1, that is, to change the moving direction of the carriage to the right or left, as shown in FIG. 6B, the operating rod 31 is bent in one direction with respect to the longitudinal directions L1 and L2. Since the connecting portion 33 is rotatable with respect to the connected portion 15, the moving direction can be easily changed.
In order to separate the carriage main body 10 and the operation tool 30, the operation tool 30 may be operated in the reverse procedure of FIGS. 5A to 5F.

According to the present embodiment, it is more preferable to use a net cage as the loading unit, particularly with regard to load collapse.

Although the operation tool 30 may be prepared for each of the plurality of carriage bodies 10, it is also possible to share one operation tool 30 with the plurality of carriage bodies 10.

In the above embodiment, although the case where the connected portion 15 is formed of a cylindrical member and the connecting portion 33 is formed of a cylindrical member is illustrated, the present invention is not limited to this, and the connecting portion 33 side is It can be formed by a cylindrical member, and the connected portion 15 side can be formed by a projecting member, and the structures of the connected portion and the connecting portion can be variously changed.
