Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention has a power section and a cargo bed section separately,
The present invention relates to a trailer in which a storage box is provided in front of and above an upper portion of a cargo bed that is pulled by a tractor equipped with a power unit and travels.

[0002]

2. Description of the Related Art In a truck in which a cab having a power section and a loading platform are integrated, a storage box is provided in front of the loading platform near the roof of the cab as shown in FIG. The outer shape of the storage cabinet is streamlined to reduce air resistance during traveling, and the evaporator and humidifier of the refrigerator are stored inside to make effective use of the inside of the cargo bed and store small valuables. For example, this storage has been effectively and widely used.

[0003]

Generally, in a large truck, since the cab tilts and tilts forward as shown by the chain line in FIG. 2, it is possible to project a storage box in the space in which the cab moves. Instead, it is necessary to incline the lower surface of the storage cabinet or to fully open the lower surface to secure a space for the cab to move. As a matter of course, it is not possible to secure a sufficient internal volume of the storage cabinet and the lower surface is inclined. Items that can be stored are also limited.

Further, the truck has a cab having a power unit and a loading platform, and the roof of the cab is located in front of the upper loading platform.
The roof of the cab is a hindrance, and work is difficult and requires special measures such as mounting before fixing the loading platform to the chassis,
It was also troublesome when it was damaged and repaired.

Further, since the roof of the cab is near the lower surface of the storage case, the joint between the storage case and the cargo bed is opened,
If you do not pass through this opening from the inside of the loading platform, you cannot load or unload items inside the storage. Therefore, when the luggage is fully loaded inside the loading platform, you cannot touch the items inside the storage from the outside. For example, it was impossible to carry out maintenance and inspection of the stored refrigeration unit and to take out only small valuables.

An object of the present invention is to easily separate the power section and the cargo bed section so that the space occupied by the storage above the front of the cargo can be sufficiently secured, and the lower surface of the storage can be made horizontal. Therefore, the items that can be stored in the storage box will be in a fairly wide range, and the storage box can be easily installed and restored without any obstruction in front of the upper part of the loading platform. Is to provide a carrier that can be carried by.

[0007] Another object of the present invention is to provide a luggage carrier having a storage container that allows an object inside the storage container to be touched from the outside of the storage container even when a lot of luggage is loaded inside the luggage carrier. Is.

[0008]

SUMMARY OF THE INVENTION To achieve the above object, the present invention is summarized as follows: a rear part of a cargo bed is supported by a rear wheel suspension device, and a coupler part of a tractor can be attached to and detached from a lower surface of a front part of the cargo bed. In addition, a king pin that engages rotatably is provided to project, the tractor pulls the tractor to travel, and the supporting leg that supports the front part of the loading platform when the vehicle is stopped and separated from the tractor is vertically expandable and contractible. In the trailer, a storage box is provided in front of the upper part of the loading platform, and the bottom of the storage box can be opened and closed. is there.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment in which the present invention is applied to a bantorera, FIG. 2 shows a case of a conventional truck, and FIG. FIG. 4 shows an enlarged view of the portion A, FIG. 4 shows another embodiment of FIG. 3, and FIG. 5 shows still another embodiment of the present invention.

Generally, in a large truck, since the cab 10 tilts and tilts forward as shown by the chain line in FIG. 2, it is not possible to project a storage in the space in which the cab 10 moves, and thus the storage It is necessary to incline the lower surface of 14 or to fully open the lower surface to secure a space for the cab to move. As a matter of course, it is not possible to secure a sufficient internal volume of the storage, and a space that can be stored when the lower surface is inclined. Is also limited.

On the other hand, the truck has a cab 1 equipped with a power unit.
Since the loading platform 12 is fixed to the chassis 16 of 0 and the roof of the cab 10 is located in front of the upper portion of the loading platform 12, the roof of the cab 10 is mounted when the storage container 14 is mounted on the upper front portion of the loading platform 12. However, it is difficult to work and requires special measures such as mounting the loading platform 12 before mounting it on the chassis portion 16, and it is similarly troublesome to repair it when it is damaged.

In view of the above circumstances, the present invention supports the rear portion of the loading platform 18 by the rear wheel suspension device 20 as shown in FIG. 1, and is attachable to and detachable from the coupler section 24 of the tractor 22 on the lower surface of the front portion of the loading platform 18. In addition, a king pin 16 that is rotatably engaged is projected, and the tractor 22 pulls the tractor 22 to travel, and when the vehicle stops and is separated from the tractor 22, the support leg 26 that supports the front portion of the cargo bed is vertically expanded and contracted. In a freely equipped trailer, a storage case 28 is provided so as to project from the front upper part of the loading platform 18, whereby a sufficient space for mounting the storage case 28 can be secured and the lower surface of the storage case can be secured. Since it can be made horizontal, the range of items that can be stored in the storage box is considerably wide. Further, when the storage box is attached or repaired, the tractor 22 can be separated so that there is no obstacle and it can be done easily.

FIG. 3 is an enlarged view of the portion A of FIG. 1, and a door 30 that can be opened and closed up and down is attached to the lower surface of the storage case 28 so that a lot of luggage is loaded on the trailer's luggage carrier 18. Even if the tractor 22 is detached, the storage 2
You can touch the inside from outside 8.

In FIG. 4, a sliding type door 32 is mounted instead of the vertically openable and closable door 30 of FIG.

FIG. 5 shows still another embodiment of the present invention. In this embodiment, the storage case 34 is made into a rectangular parallelepiped, and the air resistance during traveling is larger than that of the embodiment of FIG. 1, but the internal volume is made sufficiently large. The ventilation fan 36 is attached.

The present invention is not limited to the above-mentioned embodiments, but various design changes can be made without departing from the spirit of the present invention, for example, it can be applied to a wing trailer. Absent.

[0017]

As described above, according to the present invention, the tractor at the front part of the loading platform of the trailer can be easily separated, so that the space occupied by the storage above the front of the loading platform can be sufficiently secured, and the storage is also available. Since the bottom surface of the storage box can be made horizontal, the items that can be stored in the storage box will be in a very wide range, and the storage box can be easily attached to the upper part of the front part of the loading platform. Since there is no obstruction to the item and an opening / closing door can be attached, it is possible to touch the items inside from the outside of the storage box even when the luggage is packed inside.
