[0002]

2. Description of the Related Art Loading various goods at a goods distribution center, etc.
FIGS. 13 and 14 show conventional carts with frames used for transportation.
The following are known.

[0003] A framed trolley 50 shown in Fig. 1 is formed in a substantially rectangular parallelepiped shape having dimensions of, for example, about 1.2 m in width, 0.9 m in depth, and 1.8 m in height. That is, this framed cart 5
Reference numeral 0 denotes a left frame 51 and a right frame 52 connected by a rear frame 53, thereby forming an article storage area 54 having an open front.

The left frame 51 and the rear frame 53 are erected on an L-shaped frame 55, respectively, and are integrated so as to have an L-shape in plan view. The right frame 52 erected on a frame arranged at the same height as the L-shaped frame 55 is mounted on the shaft support 5 shown in FIG.
6 so as to be rotatable.

The shaft support 56 has a structure in which a right piece 53a of a rear frame 53 and a rear piece 52b of a right frame 52 are formed with cylindrical portions 57a and 57b at both ends of a plate-shaped support 57. Then, one cylindrical portion 57a is connected to the right side piece 5 of the rear frame 53.
3a, and the rear side piece 52b of the right frame 52 is rotatably penetrated through the other cylindrical portion 57b.

As shown in FIG. 13, a rectangular parallelepiped bottom plate 58 is detachably mounted on the lower frame of the L-shaped frame 55 and the right frame 52.

Further, on the lower frame side of the L-shaped frame 55 and the right frame 52, as shown in FIG.
A total of four casters 59 are attached,
The framed trolley 50 is movable on the floor or the ground.

In FIG. 13, reference numeral 60 denotes the left frame 5
1, a stopper piece to be hung over the front part of the right frame 52.

According to the trolley 50 with a frame, various articles can be loaded on the article storage area 54 on the bottom plate 58, and the articles can be transported by freely moving on the floor or the ground.

In addition, according to the framed cart 50, FIG.
As shown in FIG. 3, the bottom plate 58 is set upright on an L-shaped frame 55 located below the rear frame 53, and the right frame 52 is supported by the cylindrical portion 57b of the shaft support 56 as a fulcrum.
Are rotated in the direction of the arrow shown in FIG.
0 can be superimposed, and space-saving can be achieved when storing these framed carts 50.

[0011]

However, in the case of the trolley 50 with a frame described above, since the article storage area 54 has a structure in which only the front portion is opened during the loading and unloading of various articles into the article storage area 54, There is a problem that the loading and unloading of various articles can be performed only from the front side, and the efficiency of the cargo handling operation is low.

Further, in the case of the framed cart 50, since no measures are taken when moving a plurality of carts, the carts have to be moved individually one by one, and there is also a problem that these moving operations are complicated. is there.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a tow truck with a frame which can improve the efficiency of cargo handling work and can simplify a plurality of moving work.

[0014]

According to the present invention, a flat shape is used.
With respectively erected and left right side frame and the rear frame body arranged L-shaped frame on such a shape, arranged detachably bottom plate on the L-shaped frame, the left frame, along with the the rear frame and the right frame body and the bottom plate front part to form an article accommodating space which is open in the framed towing truck fitted with casters to L-shaped frame, the left frame body wherein Move to the L-shaped frame
And is provided rotatably with respect to the rear frame body, and is attached to one of the left frame body and the right frame body, and to a connecting piece for connection to another towed trolley with a frame attached to one of the left frame body and the right frame body and attached to one of the other. And a traction connection mechanism comprising a connection receiving piece with which a connection piece of another traction truck with a frame can be engaged.

[0015]

According to the above-described towing vehicle with a frame, the left frame is rotatably supported by the shaft support with respect to the rear frame, so that when loading and unloading articles , the rear frame is placed on the L-shaped frame. frame
With only the body and the right frame upright , only the left frame is outward
It is possible to form an article accommodating area in which the left side is opened in addition to the front in the opened state, thereby improving the efficiency of the cargo handling operation. Also, according to this framed towing truck, a connection piece for connection to another framed towing truck attached to one of the left frame and the right frame, and another frame attached to one of the other. Since the towing coupling mechanism portion is provided with a coupling receiving piece with which the coupling piece of the towing vehicle can be engaged, a plurality of towing vehicles with frames can be successively connected using the coupling piece and the coupling receiving piece of the towing coupling mechanism portion. Thus, it is possible to simplify the operation of moving a plurality of framed towing vehicles.
