In other respects, the configuration is the same as that of the third embodiment, and the operation is the same.

Thus, even if this stopper member 53 is used, the third
The same effect as that of the embodiment can be obtained.

16 and 17 show a fifth embodiment of the present invention, in which a bogie main body 62 is used in place of the bogie main body 2 in the first embodiment, and the luggage 6 is prevented from slipping forward.
Unlike the above embodiments, the swing member 20 and the stopper members 43, 5
3 is performed without using the roller conveyor brake 9 alone.

That is, the bogie main body 62, as shown in FIG.
The upper surface is composed of a gentle slope portion 62a that gradually slopes down toward the tip and a steep portion 62a that slopes down toward the tip at a steep angle. As shown in FIGS. 16 and 17,
A total of seven roller conveyors 5 are provided, and the load 6 loaded on the cab 1 comes into contact with only the five roller conveyors 5 of the gentle slope portion 62a as shown in FIG. I have. The two roller conveyors 5 of the steeply inclined portion 62b come into contact with the load 6 only when unloading.

16 and 17 are provided on the lower surface of the bogie main body 62.

The roller conveyor 5 is disposed over the five roller conveyors 5 of the gentle gradient section 62a, so that the rotation of the three roller conveyors 5 passing through the lower side can be fixed.

In other respects, the configuration is the same as that of the first embodiment, and the operation is almost the same.

Thus, as in the case of the third and fourth embodiments, the luggage 6 is loaded with a slight forward inclination following the inclination of the gentle slope portion 62a. As a result, the rotation of the three roller conveyors 5 is fixed, so that forward sliding can be prevented. In addition, since there is no obstacle on the tip side of the bogie main body 62, as shown in FIG. 16, even if the luggage 6 is larger than the bogie main body 62, it can be transported without any trouble. Can be reduced in size.

In each of the above-described embodiments, the case where the traveling wheel 4 is formed of a roller or a crawler is described. However, another structure such as a caster structure may be used.

Although not particularly described in the above embodiment, the transport trolley 1 has a structure that can be divided into left and right at the center in the width direction, and in the case of a narrow luggage, only one of them is used. In the case of a large luggage, the left and right sides may be connected and used.

[Effects of the Invention] As described above, in the first invention of the present invention, the upper surface having the rolling roller is inclined downward toward the front end at the tip of the bogie main body having the conveyor roller provided on the upper surface. Since the swing member is provided and the load on the bogie body is unloaded by utilizing the inclination of the upper surface of the swing member, the unloading can be easily and surely performed only by human power, and the unloading can be performed. There is no risk of collapse of the load at the time.

In addition, since the carriage body is provided with a brake for the conveyor roller, even if the luggage is small compared to the carriage body, the luggage does not inadvertently move on the carriage body during transportation. In both cases, even if the luggage is larger than the bogie main body and the swinging member cannot be swung upward, it is possible to prevent the luggage from accidentally slipping out of the bogie main body.

Also, since the structure of the brake is extremely simple, there is almost no increase in the weight of the bogie body, and the bogie is easy to handle, and the brake lever is temporarily fixed to the brake release position and the brake operating position by a spring. Operation is reliable and high reliability is obtained.

In the second invention of the present invention, the upper surface of the bogie main body provided with the conveyor roller is inclined downward toward the front end, so that the first member is provided without a swing member.
The same effect as in the invention of the present invention can be obtained, and even if the upper surface of the bogie body is inclined by the stopper for preventing the luggage from sliding toward the front end of the bogie body, there is no problem that the luggage falls off before unloading .

In addition, since the carriage body is provided with a brake for the conveyor roller, even if the stopper can not be used, it will only lightly hold the luggage and prevent it from sliding to the tip of the carriage body This is especially effective for large luggage.

Also, since the structure of the brake is extremely simple, there is almost no increase in the weight of the bogie body, and the bogie is easy to handle, and the brake lever is temporarily fixed to the brake release position and the brake operating position by a spring. Operation is reliable and high reliability is obtained.
