Description

[DESCRIPTION] [Invention Title]

FREIGHT CONTAINER FOR CAR TRANSPORTATION [Technical Field]

<i> The present invention relates to a freight container for car transportation. [Background Art]

<2> Generally, containers are one kind of case for transportation and, particularly, are cases which have a standard size and receive relatively large of cargo therein for land transportation or oceanic transportation. In other words, such cases used for safely and conveniently transporting cargo are referred to as containers. As such, the containers are standardized receptacles for large cargo.

<3> Meanwhile, in the case of cargo to be loaded in such a container, most cargo is packed in packing cases, so that the cargo is typically loaded in the container as packed units. Furthermore, when loading or unloading cargo, typically, in a state in which the container is placed on or separated from a trailer, the cargo is loaded or unloaded using the labor of workers or heavy machines such as forklifts.

<4> FIG. 1 is a perspective view showing a freight container according to a conventional technique.

<5> As shown in the drawing, the conventional freight container has a rectangular parallelepiped framework structure. In detail, the freight container includes upper and lower frames, which are provided at upper and lower positions. Pockets, into which the forks of a cargo-handling machine such as a forklift are inserted to handle the container, are formed at predetermined positions in the lower frame.

<6> Furthermore, corner posts are provided on corners of the upper and lower frames, thus forming the framework of the container.

<7> Each corner post is manufactured by forming a steel plate, which is a hot rolled steel section and has a thickness ranging from 4mm to 10mm, into a rectangular column shape and by welding the column-shaped steel plate. The corner posts serve to support a vertical load such that several containers are stacked on each other. In addition, a casting, to which a wire of a crane is connected, but which is not shown in the drawings, may be integrally formed in each corner post .

<8> Meanwhile, panels, each of which has a corrugated surface, are connected in and between the upper and lower frames to form a cover, a bottom, sidewalls, a front wall and a rear wall. Each corrugated panel is formed by bending a steel plate having a predetermined thickness into a corrugated shape, thus increasing the strength of the panel.

<9> The freight container having the above-mentioned construction is loaded on or unloaded from a desired position using a loading and unloading machine such as a crane. Several freight containers are placed and lashed into a shape such that they can be stacked on each other.

<io> In the case of the conventional freight container, when cars are loaded in the freight container, because the height of the container is much greater than the height of the cars, a relatively large space is defined in the container. However, due to the characteristics of the cars, other cargo cannot be stacked on the cars. Therefore, the conventional freight container is disadvantageous in that the utilization of space is very inefficient.

<ii> Meanwhile, car transportation by sea is mainly conducted using ships that exclusively transport cars. Typically, the ship for car transportation has a shape like a ten or more storied parking structure provided with a propulsion device, and has a loading capacity of 5000 cars or more. In this way, cars are transported in large quantities, and, typically, a loading and unloading operation is conducted at wharf dedicated to cars. However, in the case where there is no wharf dedicated to cars, or where it is desired to transport a small amount of cars, conventional freight containers are used. Here, as described above, there is a disadvantage in that the containers occupy excessively large space. [Disclosure] [Technical Problem]

<12> Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a freight container for car transportation which includes a supplemental frame body that is provided to form a double bottom structure, and includes a middle frame and a middle panel having a corrugated surface, such that loading space in the container is partitioned into upper and lower spaces, so that the utilization of space for loading cars can be optimized. [Technical Solution]

<13> In order to accomplish the above object, the present invention provides ' a freight container for car transportation, including upper, middle and lower frames provided at upper, middle and lower positions, panels provided in the respective upper, middle and lower frames to form a cover, a first bottom and a second bottom, each of the panels having a corrugated surface, corner posts provided at four respective corners to support a vertical load, and medial posts provided to ensure the strength of the container, wherein reinforcing frames, each having an 'X' shape, are provided between the medial posts to withstand torsion load and oblique load.

<14> In one aspect, in the freight container for car transportation, the total height of the container is 12 feet, and thus the height of a single loading space is 5 feet.

<15> In another aspect, the freight container has no door or side panels, thus realizing an open structure such that cars are freely loaded into and unloaded from the container. [Advantageous Effects]

<16> As described above, in a freight container for car transportation according to the present invention, a loading space is partitioned into upper and lower spaces, so that the efficiency with which cars, as well as motorcycles, farm machines, etc. are transported is markedly increased. Thereby, there is an advantage in that transport costs are markedly reduced. [Description of Drawings]

<26> The present invention relates, in general, to freight containers for car transportation and, more particularly, to a freight container for car transportation which includes a supplemental frame body that is provided to form a double bottom structure and includes a middle frame and a middle panel having a corrugated surface, such that the loading space in the container is partitioned into upper and lower spaces, so that the utilization of space for loading cars can be optimized. [Mode for Invention]

<27> Hereinafter, a freight container for car transportation according to a preferred embodiment of the present invention will be described with reference to the attached drawings.

<28> FIG. 2 is a perspective view of the freight container for car transportation according to the present invention. FIG. 3 is a side view showing the freight container of FIG.2.

<29> As shown in the drawings, the freight container for car transportation according to the present invention includes an upper frame 11, a middle frame 12 and a lower frame 13, each of which has a rectangular shape. The upper frame 11, the middle frame 12 and the lower frame 13 are disposed at positions spaced apart from each other in a vertical direction at regular intervals. Furthermore, corner posts 10 are provided on four corners of the frames. Medial posts 20 and reinforcing frames 30 are integrally coupled to the above components, thus forming the framework of the freight container.

<30> Here, each corner post 10 is manufactured by forming a steel plate having a predetermined thickness into a rectangular column shape and welding the column-shaped steel plate. The corner posts 10 serve to support a vertical load such that several containers are stacked on each other. In addition, a casting, to which a wire of a crane is connected, but which is not shown in the drawings, is integrally formed in each corner post 10. The corner posts 10 are fastened to the upper frame 11, the middle frame 12 and the lower frame 13 by welding, bolting or the like.

<3i> The framework of the freight container having the above-mentioned box shape is provided with an upper panel 21, and middle and lower panels 22 and 23, on which cars are loaded, thus forming a structure such that sidewalls of the framework are open. Each of the upper, middle and lower panels 21, 22 and 23 is formed into a board shape having a corrugated surface formed by bending. Here, the corrugated surface formed in each panel serves to increase the strength of resistance to external force, so that, as shown in the drawings, the corrugations are formed in directions in which the ability to withstand external force applied in the vertical direction is increased.

<32> Furthermore, the freight container is provided with hooks for lashing cars and a hinged plate, which prevents the wheels of the cars from being held, so that the cars can be easily loaded and unloaded.

<33> Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, the present invention is not limited to the above embodiment. Those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention disclosed in the accompanying claims. Therefore, the modifications, additions and substitutions must be regarded as falling within the bounds of the present invention. [Industrial Applicability] <34> As described above, the present invention provides a freight container for car transportation which has a structure such that a loading space is partitioned into upper and lower spaces, thus markedly increasing the efficiency with which cars, as well as motorcycles, farm machines, etc., are transported, thereby markedly reducing transport costs.

<35> Furthermore, compared to the conventional art, a large amount of freight can be loaded in the container. In addition, the present invention can be used for land transportation, thus being very economical.
