Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container.

[0002]

2. Description of the Related Art In a luggage carrier used in a steel mill, a smelter, a shipyard, etc., a container is held on its carrier.
Items to be transported such as heavy items, large-capacity items, and long items are loaded in this container. That is, the load is loaded from above the container, and the load is unloaded from the open rear end of the container by inclining it toward the rear side by hydraulic lifting means or the like.

Conventionally, since this kind of luggage carrier is generally operated only in a limited area, there is no rear door at the rear end of the container, and the rear is always open. However, in this case, the load cannot be loaded near the rear end area of the container in order to prevent the load from falling during transportation. On the other hand, even if a rear door is provided in the container for loading loads near the rear end area of the container, this type of luggage carrier is usually very large, so it is difficult to reach the position of the rear door and the opening and closing of the door is difficult. It's very difficult to do.

[0004]

Therefore, it is an object of the present invention to provide a container having a rear door and which can be easily opened and closed.

[0005]

In order to solve the above problems, the present invention takes the following technical means. The container of the present invention is a container that can be tilted rearward about a rotation axis between the container and the bed of the luggage carrier, and the main body has a rear end that is rotatable with respect to the upper side. The rear door is provided with an opening / closing means, and the opening / closing means of the rear door is a base formed on a luggage carrier of a luggage carrier, and one end side of the opening / closing means is rotatable with respect to the base. In addition, the main body has a rear portion in the main body, which is rotatable about an axis near the rear door, and a locking portion with the other end of the arm portion formed in the rear door. When the distance between the center of rotation of the arm near the rear door and the base becomes a certain distance or more, the engagement state between the other end of the arm and the locking portion of the rear door Is released.

[0006]

As a result of adopting the above means, the present invention has the following effects. When the container body inclines rearward during unloading, the center of rotation of the arm near the rear door faces rearward with respect to the center of rotation between the luggage carrier and the container. Displaces in an arc. That is, the distance between the center of rotation of the arm, which is displaced in an arc shape while its one end side rotates with respect to the base, and the base formed on the luggage carrier, increases. Then, when this distance becomes equal to or greater than a certain value, the engagement state between the other end side of the arm portion and the locking portion of the rear door is released. Therefore, the rear door that is rotatable with respect to the upper side of the rear end of the main body is opened. As described above, the rear door of the main body automatically opens as the main body tilts rearward.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below with reference to the accompanying drawings. In this embodiment, a container 2 as shown in FIGS. 3 and 4 is held by a known method on a carrier 10 of a luggage carrier 1 as shown in FIGS. 1 and 2. In this embodiment, the container 2 is constructed separately from the cargo bed 10. When the container 2 is connected to the loading platform 10, the container 2 is raised while being held by a known container holding mechanism (not shown) formed on the loading platform 10. On the contrary, when the container 2 connected and held to the loading platform 10 is separated, the container 2 is lowered while holding the container 2 by the container holding mechanism of the loading platform 10. However, the cargo bed 10 and the container 2 are not separately configured as described above, and like the so-called dump truck in the luggage carrier 1,
The luggage carrier 10 and the container 2 may be connected in advance. That is, the container 2 and the luggage carrier 10 may be separate bodies or may be connected in advance.

The container 2 is opened at the top and is designed to be loaded with objects to be transported such as heavy objects, large-capacity objects, and long objects. That is, the load is loaded from above the container 2, and the load is unloaded from the rear end of the container 2 by inclining it toward the rear side by hydraulic lifting means (not shown). As shown in FIGS. 5-8, the container 2 of this embodiment
Is formed so that it can be inclined toward the rear side as described above about the rotation axis 11 between the luggage carrier 1 and the bed 10. A rear door 21 that is rotatable with respect to the upper side 20 is provided at the rear end of the main body of the container 2.
The opening / closing means 3 as described below is provided.

The opening / closing means 3 for the rear door 21 has the following structure. Base 4 formed on luggage carrier 10 of luggage carrier 1
An arm portion 5 having one end thereof rotatable with respect to the base portion 4 and rotatable about a shaft 50 near the rear door 21 in the main body, and the arm portion formed on the rear door 21. 5 and the engaging portion 6 with the other end side. The arm 5 is formed in detail as follows. A substantially "V" -shaped portion 52 in which a locking groove 51 that engages with the locking portion 6 of the rear door 21 is formed, and is rotatable to the opposite end side of the substantially "F" -shaped portion 52. It is a hook-shaped portion 53 that is pivotally supported and that should be engaged with the base portion 4 formed on the luggage carrier 10 of the luggage carrier 1. When the container 2 is connected to the loading platform 10 and is raised while holding the container 2 by the container holding mechanism formed on the loading platform 10, the hook area 53 is attached to the base 4 formed on the loading platform 10 of the luggage carrier 1. Engage.
The substantially "V" -shaped portion 52 is rotatable about the shaft 50 near the rear door 21 in the main body at the center thereof. Further, the hook-shaped portion 53 is provided with a known length adjusting mechanism 54.

In order to prevent the risk of the engagement state between the engagement groove 51 on the other end side of the arm 5 and the engagement portion 6 of the rear door 21 being released too violently, in order to prevent the danger, The spring bias 7 is applied downward in the vicinity of the locking groove 51 of the character-shaped portion 52. Further, as shown in FIG. 3, when the container 2 is in a separated state where it is not held on the luggage carrier 10 of the luggage carrier 1, the hook-shaped portion 53 hangs downward. Then, when the container 2 is raised so as to be held on the luggage carrier 10 of the luggage carrier 1, the hook-shaped portion 53 shifts to a state in which it can be engaged with the base portion 4.

When the container 2 main body inclines rearward from the state of FIG. 5 as shown in FIGS. 6 to 8 when unloading, the space between the cargo bed 10 of the luggage carrier 1 and the container 2 is lowered. With respect to the rotation center 11, the rotation center 50 of the arm portion 5 near the rear door 21 is displaced rearward in an arc shape. That is, the distance between the rotation center 50 of the arm 5 and the base 4 formed on the luggage carrier 10 in which the hook-shaped portion 53 on one end side is displaced in an arc while rotating with respect to the base 4. L grows. Then, as shown in FIG. 7, when the distance L becomes a certain value or more, the engagement state between the engagement groove on the other end side of the arm portion 5 and the locking portion 6 of the rear door 21 is released. Therefore, as shown in FIG. 8, the rear door 21 that is rotatable with respect to the upper side 20 of the rear end of the main body is completely opened. As mentioned above, the rear door 21 of the container 2
Automatically opens as the body tilts backwards.

That is, even if a rear door 21 is provided in the container 2 for loading a load near the rear end area of the container 2 in the related art, since this kind of luggage carrier 1 is usually very large, the position of the rear door 21 is quite difficult. It was difficult to open and close it because it could not be reached, but in the container 2 of this embodiment, since the rear door 21 of the main body automatically opens as the main body tilts backward, the opening and closing of the rear door 21 is performed. Has the advantage of being easy.

Further, since the rear door 21 is provided at the rear end portion of the container 2, there is an advantage that the load can be loaded up to the vicinity of the rear end region of the container 2. When the container 2 and the loading platform 10 are configured as separate bodies as in the above embodiment, they need to be detached from each other, but the mutual positional relationship inevitably changes when detaching (when connecting, Since the container 2 is held by the cargo bed 10 and rises), it is necessary to provide an automatic opening / closing means for the rear door in comparison with a container such as a dump truck that is configured by connecting the container and the cargo bed with a small degree of relative change. The attribute that is difficult is inevitably inherent.

However, the opening / closing means 3 of the rear door 21 having the above-mentioned structure necessarily has the attribute that it is difficult to provide the automatic opening / closing means of the rear door. It has the advantage that it can also be used for body configurations.

[0015]

The present invention has the above-mentioned structure and has the following effects. Since the rear door of the main body is automatically opened as the main body is tilted rearward, it is possible to provide a container having the rear door and easily opened and closed.
