Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates primarily to containers for shipping cargo.

0002

[Prior art and its problems] Generally, this type of container is lifted and suspended (cargo handling) by a crane, so corner fittings for hooks connected to the crane wire are provided at the four corners of the upper end of the container body. It is being (See Figure 1)

As shown in FIGS. 5 and 6, the corner fittings include a top plate 1 located on the top surface of the container body A, a side plate 2 extending perpendicularly to the top plate 1 located on the side surface of the container body A, and the above-mentioned corner fittings. A bottom plate 4 is connected perpendicularly to the side plate 2 which faces the lower side of the top plate 1 via a required space 3, and a hook hook portion 5 is formed remaining at the orthogonal part between the top plate 1 and the side plate 2. It consists of hook insertion windows 1a and 2a provided in the top plate 1 and side plates 2.

[0004] To hook the hook onto the corner fitting, the hook is inserted into the bottom plate 4 through the window hole 1a of the top plate 1, and the tip end of the hook is made to protrude from the window hole 2a of the side plate 2. By pulling up the wire in this state, the hook will be caught on the hook part 5 facing directly above the wire, and the container will be lifted up. However, the problem is that the window hole 2
a has a large vertical and horizontal dimension as shown in Fig. 6 in order to facilitate the insertion operation of the hook, and as a result, the hook does not fit inside the window hole 2a due to the slack of the wire as shown by the solid line in the figure. It tilts in an unstable posture, and due to this tilt, the tip of the hook part of the hook is positioned below the bottom surface of the hook part 5 due to a change in the distance connecting the tip of the hook part and the top surface of the bottom plate 4 with a vertical line. Therefore, when the wire is pulled up in this state, the hook will be retracted inward from the window hole 2a as shown by the imaginary line due to irregular direction movement of the wire from the slack state to the time when tension is applied. In this case, of course, there is a risk that the hook will be pulled out from the window hole 1a of the top plate 1 without being caught on the hook portion 5, and the container will fall.

[0005] Therefore, the present invention maintains the end rod portion of the hook inserted into the window hole 2a of the side plate 2 in an upright position,
The purpose of this is to ensure that the hook is always caught on the hook part 5 when pulling up the wire, thereby preventing the risk of the container falling, which was a problem with conventional products.

[0006]

[Means for Solving the Problems] To achieve the above object, the present invention includes a top plate located on the top surface of the container body, and a top plate located on the side surface of the container body, at the four corners of the top end of the container body. a side plate that is continuous at a right angle to the side plate, a bottom plate that is continuous at a right angle to the side plate that faces the lower side of the top plate through a required space, and a hook hooking portion is formed remaining at the orthogonal part between the top plate and the side plate. In a container in which a corner fitting consisting of a window hole for hook insertion provided in the top plate and the side plate, respectively, is provided,
An introduction guide having a narrower width than the above-mentioned window hole for introducing into the outer surface side of the window hole provided in the above-mentioned side plate the tip end portion of the hook that communicates with the window hole and projects outside through the window hole in an upright position. The main point is that it has been established.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, A is a container body made of iron plate, and corner fittings B are provided at the four corners of the upper end of the container body. This corner fitting B has a hollow rectangular shape, so that at least the top plate 1 located on the top surface of the container main body A, as in the previous conventional example.
and a side plate 2 that is perpendicular to the top plate 1 located on the outer surface of the container body, and a bottom plate 4 that is perpendicular to the side plate 2 and opposite to the bottom of the top plate 1 with a required space 3 in between. ,
In addition, window holes 1a and 2a for hook insertion are provided in the top plate 1 and the side plates 2 so that a downward hook hook portion 5 is formed at the orthogonal part between the top plate 1 and the side plates 2. ing.

Therefore, the gist of the present invention is that a hook is provided on the outer surface side of the window hole 2a provided in the side plate 2, communicating with the center of the window hole 2 and projecting to the outside through the window hole 2. The window hole 2a into which the tip end portion of the rod is introduced in an upright position.
A narrower introduction guide 6 is provided.

As a specific example of the introduction guide 6, in this example, a contact plate 6a having the same shape and size as the side plate 2 is attached and fixed to the outer surface of the side plate 2, and the hook is attached to this contact plate 6a. It is constructed by forming a vertically long notch 6b that is slightly wider than the thickness of the tip end portion and narrower than the window hole 2a. Further, the bottom end of this notch 6b is aligned with the top surface of the bottom plate 4 of the corner fitting. Further, at the upper end of the notch 6b, there is formed a relief part 6c for a hook when lifting a container, which is opened wider than the notch 6b. In this example, the introduction guide 6 is constructed by adhering the contact plate 7, but it may be formed integrally with the corner fitting. Further, although this is not directly related to the present invention, since the introduction guide 6 has a thickness, it is possible to increase the size of the container by this thickness.

0010

[Operation] The operation of hooking the hook onto the corner fitting will be described below. As shown in FIG. 3, when the hook is inserted onto the bottom plate 4 through the window hole 1a of the top plate 1, and the tip end of the hook is inserted into the window hole 2a of the side plate 2, the front part of the window hole 2a is inserted. Since the guide, that is, the notch 6b, communicates with each other, the tip of the hook is introduced into the notch 6b, and the hook is maintained in an upright position without tilting. Since the wire is raised vertically from the lower surface of the hook 5 and the wire is pulled up in this state, the hook is always hooked on the hook 5 and the container can be lifted up safely.

[0011]

As described above, according to the present invention, the end rod portion of the hook that protrudes outside through the window hole is introduced in an upright position on the outer surface side of the window hole of the side plate constituting the corner fitting. Since the introduction guide is provided with a narrower width than the window hole, this introduction guide always maintains the hook in an upright position where it is caught on the hook of the corner fitting, thereby solving the problem that occurred in the prior art, that is, configuring the corner fitting. This solution solves the problem of the hook tilting due to the large hook insertion hole in the side plate, and the container falling due to the hook detaching from the window hole due to this tilt. It has the following characteristics.
