DETAILED DESCRIPTION OF THE INVENTION

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

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 a carrier thereof.
Loaded objects such as heavy objects, large-capacity objects, and long objects are loaded on the container. That is, the load is loaded from above the container, and the load is tilted rearward by hydraulic lifting means or the like, and the load is unloaded from the open rear end of the container. 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 dropping during transportation. On the other hand, even if a container is provided with a rear door in order to load cargo near the rear end area of the container, this kind of luggage carrier is usually very large, so it is difficult to reach the rear door position and it can be opened and closed. Hard to do.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a container having a rear door and which can be easily opened and closed.

In order to solve the above-mentioned problems, the present invention employs the following technical means. The container of the present invention is a container which can be inclined rearward around a rotation axis between the carrier and the carrier of the luggage carrier, is configured as a separate body from the carrier, and has a rear end portion of the main body thereof. The vehicle has a rear door rotatable with respect to an upper side, and the rear door is provided with opening / closing means. The opening / closing means for the rear door includes a base formed on a bed of a luggage carrier and a main body. Ke
Can rotate around an axis near the rear door and load
The hooks to be engaged with the base formed on the carrier
Has between arm portion having at one end, and a locking portion of the other end of the arm portion formed in the rear door, the base wherein the hook-shaped portion is engaged
Together is pivotable about the said hook-shaped portion and raises the container upon coupling the loading platform to the container engages the base formed on the rear luggage truck, have inclined body rearward When the distance between the center of rotation of the arm near the rear door and the base becomes equal to or greater than a certain value, one end of the arm
The hook on the side is engaged with the base, and the other end of the arm can be displaced.
Since the performance range is constrained, the engagement between the other end of the arm portion and the locking portion of the rear door is released.

As a result of adopting the above means, the present invention has the following functions. When the container is lifted when the carrier is connected to the container, the hook on one end of the arm engages with the base formed on the carrier of the luggage carrier. When unloading, if the container body is inclined rearward, the center of rotation of the arm near the rear door faces rearward with respect to the rotation axis between the luggage carrier and the container. Displaces in an arc.
In other words, the distance between the center of rotation of the arm, which is displaced in an arc while the hook-like portion on one end of the arm is rotated with respect to the base, and the base formed on the carrier, is elongated. Go. When this distance exceeds a certain value, the hook at one end of the arm is
And the movable range of the other end of the arm is restricted.
As a result , the engagement state between the other end of the arm portion and the locking portion of the rear door is released. Therefore, the rear door that can rotate 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 is automatically opened as the main body is inclined rearward. That is, as compared with a container such as a dump truck in which the container and the loading platform are connected and the degree of relative change is small, the mutual positional relationship when the container and the loading platform are detached greatly changes, and the rear door Although it is difficult to provide automatic opening and closing means, the rear door of the main body automatically opens as the main body tilts backward.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the drawings showing an embodiment. In this embodiment, a container 2 as shown in FIGS. 3 and 4 is held on a carrier 10 of a luggage carrier 1 as shown in FIGS. 1 and 2 by a known method. In this embodiment, the container 2 is configured separately from the carrier 10. When the container 2 is connected to the carrier 10, the container 2 is raised while holding the container 2 by a known container holding mechanism (not shown) formed on the carrier 10. Conversely, when separating the container 2 connected and held from the bed 10, the container 2 is lowered while holding the container 2 by the container holding mechanism of the bed 10. The container 2 is open at the top, and carries a load such as a heavy object, a large-capacity object, or a long object. That is,
The load is loaded from above the container 2 and tilted rearward by a hydraulic lifting / lowering means (not shown) to unload the load from the rear end of the container 2. 5 to 8
As shown in FIG. 1, the container 2 of this embodiment is formed so as to be inclined rearward as described above around the rotation shaft 11 between the container 2 and the luggage carrier 1. A rear door 21 is provided at the rear end of the main body of the container 2 so as to be rotatable with respect to the upper side 20. The rear door 21 is provided with opening / closing means 3 as described below. Opening / closing means 3 for rear door 21
Has the following configuration. A base 4 formed on the carrier 10 of the luggage carrier 1 and a shaft 5 near the rear door 21 of the main body;
0 and the load of luggage carrier 1
The hook 53 to be engaged with the base 4 formed on the base 10 is removed.
Arm 5 provided on one end side of the
And the locking portion 6 with the other end of the arm portion 5. The hook 53
Are rotatable around the engaged base 4.
The arm 5 was formed in detail as follows. A substantially "H" -shaped portion 52 having a locking groove 51 for engaging with the locking portion 6 of the rear door 21 and a rotatable pivot on the opposite end side of the substantially "H" -shaped portion 52. The hook-shaped portion 53 that is supported by the shaft and is to be engaged with the base 4 formed on the carrier 10 of the luggage carrier 1. Bed 10
When the container 2 is connected to the container 2, the container 2 is raised while holding the container 2 by a container holding mechanism formed on the loading platform 10.
The hook 53 engages with the base 4 formed on the carrier 10 of the luggage carrier 1. The substantially "H" -shaped portion 52 is rotatable at its center about a shaft 50 near the rear door 21 of the main body. The hook 53 has a known length adjusting mechanism 54. In order to prevent a risk that the engagement state between the locking groove 51 on the other end side of the arm portion 5 and the locking portion 6 of the rear door 21 is excessively severely released,
The vicinity of the locking groove 51 of the substantially "H" -shaped portion 52 is biased by a spring 7 downward. As shown in FIG. 3, when the container 2 is in a separated state in which the container 2 is not held on the carrier 10 of the luggage carrier 1, the hook 53 is hung downward. Then, the container 2 is loaded on the luggage carrier 1 of the luggage carrier 1.
When the hook-shaped portion 53 is raised to hold it at 0, the hook-like portion 53 shifts to a state where it can be engaged with the base portion 4. At the time of unloading, as shown in FIGS. 6 to 8, when the container 2 main body is inclined rearward from the state shown in FIG. 5, the rotation axis between the loading platform 10 of the luggage carrier 1 and the container 2 is increased. In contrast to 11 , the center of rotation 50 of the arm 5 near the rear door 21 is displaced backward in an arc shape.
That is, the center of rotation 50 of the arm 5 is displaced in an arc while the hook 53 at one end of the arm 5 is rotated with respect to the base 4.
And the distance L between the base and the base 4 formed on the carrier 10 increases. As shown in FIG. 7, when the distance L is equal to or greater than a predetermined value, the hook 53 at one end of the arm 5 is
4 and the movable range of the other end of the arm 5 is restricted.
The engagement groove on the other end of the arm 5 and the rear door 2
The engagement state with the locking portion 6 is released. Therefore,
As shown in FIG. 8, the rear door 21 that can rotate with respect to the upper side 20 at the rear end of the main body is completely opened. As described above, the rear door 21 of the container 2 is automatically opened with the rearward inclination of the main body. In other words, conventionally, even if the rear door 21 is provided in the container 2 for loading the load near the rear end area of the container 2 as well, since the luggage carrier 1 of this kind is usually very large, it is quite difficult to reach the position of the rear door 21. Although it was difficult to reach and open and close the container, the container 2 of this embodiment opened automatically when the rear door 21 of the main body was tilted rearward of the main body, so that the opening and closing of the rear door 21 was easy. It has the advantage of being. Further, since the rear door 21 is provided at the rear end of the container 2, there is an advantage that the load can be loaded near the rear end of the container 2. When the container 2 and the loading platform 10 are configured separately as in the above-described embodiment, they need to be detached and attached to each other, but when detached, the mutual positional relationship inevitably changes greatly (when connected, Since the container 2 is held by the loading platform 10 and rises), it is necessary to provide an automatic opening / closing means for the rear door as compared with a configuration in which the container and the loading platform are connected to each other like a dump truck and the degree of relative change is small. The attribute that is difficult is inevitable. However, the opening / closing means 3 for the rear door 21 having the above-described configuration necessarily has an attribute that it is difficult to provide an automatic opening / closing means for the rear door. There is an advantage that it can be adopted also in the case of

The present invention has the above-described configuration and has the following effects. The relative position of the container and the loading / unloading platform changes significantly compared to a container with a loading / unloading truck that has a linked container and a small relative change. Although it is difficult to provide a suitable opening / closing means, the rear door of the main body is automatically opened with the rearward inclination of the main body, so that a container having a rear door and easy to open / close is provided. I can do it.
