Description

[Detailed Description of the Invention] The present invention relates to a flat rank container, which is easy to handle, safe, easy to manufacture, does not break down, and has a good appearance.

A flat rank container does not have a roof and is used with a tarpaulin over it if necessary, and is mainly used for transporting large machinery such as lumber, construction, or agricultural machinery.

Specifically, a flat rack container does not have side panels, and the floor member is provided with end panels at both ends so that the container can be folded onto the floor member when not in use.

The end panel is specifically composed of an end panel in a narrow sense and corner posts provided on both sides of the end panel,
The lower ends of the corner posts on both sides are pivotally supported on the floor member side with pins or the like, so that it can be folded onto the floor member.

However, conventional flat rack containers have the drawback that folding or raising the end panels requires time and effort, and handling thereof is dangerous.

In other words, all containers, not just flat rack containers, are made of metal such as iron to withstand the transportation of heavy objects, and the end panels of flat rack containers are also heavy, requiring a large amount of force to fold or stand up.
Particularly when folding, one had to be careful not to pinch one's hands, feet, etc., which was extremely dangerous.

As a result, impact is applied to the folding mutto floor members and end panels due to their own weight, which impairs their durability, and also causes damage to the corner posts, making it difficult to stack containers that can be buttoned at the corner posts.

In order to eliminate the above-mentioned drawbacks, the present invention is configured so that a brake is automatically applied when the end panel is folded, and a restoring force is applied when the end panel is erected.As a result, it is safe when folded and when erected. It requires only a small amount of force to move, making it extremely easy to handle.

It is conceivable to use a coil spring or the like as a means of constructing the invention as described above, but in that case, there are drawbacks in terms of durability, failure is likely to occur, furthermore, it is time-consuming to manufacture, and it is also aesthetically undesirable. This causes problems such as exposure of the coil spring.

The present invention also eliminates the above-mentioned drawbacks.

An embodiment of the present invention will be described in detail below with reference to the drawings.

End panels 2 are provided at both ends of the 7o amenper 1 so as to be foldable.

The floor member 1 is provided with bottom site rails 3 made of H-shaped steel on both sides, and a cross member 4 made of channel material or the like is provided at an appropriate interval between them, and a floor board 5 is stretched on the upper surface of the cross member 4. It consists of

Furthermore, the end panel 2 is provided with corner posts 6 on both sides thereof, and a mounting bracket 7 is provided at the lower end of each corner post 6, and the other end of the mounting bracket I is pivotally supported on the floor member 1 side with a pin or the like. It is constructed so as to be foldable on the floor member 1.

The button 8 in the figure is a corner fitting with a stopper effect provided at the four corners of the floor member 1, and the end panel 2
, when the corner post 6 is erected, the lower end of the corner post 6 rests on it and acts to prevent the end panel 2 from falling outward, and the mounting bracket 7
A through hole 11 is provided at a predetermined position to match the through hole 9 provided in the end panel 2, and by inserting a pin 12 between the two through holes 9 and 11, the end panel 2 will not fall down toward the floor member 1 side. It is intended to do so.

In the present invention, when the end panel 2 is pivoted, specifically, the other end of the mounting bracket 7 provided at the lower end of the corner post 6 on both sides of the end panel 2 is pivoted to the floor member 1, the conventional Instead of a pin, a single metal rod 10 is used.

The metal rod 10 is made of a metal that has a restoring force against twisting, and its diameter is selected in consideration of the weight of the end panel 2.

In the present invention, the metal rod 10 is inserted at a predetermined position of the bottom end rail 3, that is, between the shaft supports at both ends of the end panel 2, and when the end panel 2 is erected, both ends thereof are on the end panel 2 side, specifically, is inserted through and fixed to the other end of the mounting bracket 7 at the lower end of the corner post 6 constituting the end panel 2, and its substantially central portion is fixed to the floor member 1 side.

Although welding is appropriate for fixing the mounting bracket 7 and the metal rod 10, it is also possible to bend both ends of the metal rod 10 and lock the bent ends at appropriate positions on the mounting bracket 7.

Although the approximately central portion of the metal rod 10 and the floor member 1 may be fixed by welding to the cross member 4 that constitutes the floor member 1, in the case of the embodiment, approximately the center portion of the metal rod 10 A curved part 10' is provided in the center, and the top part thereof is fixed to the floor member 1 side.

That is, when the metal rod 10 is made straight and its approximately central portion is welded to the cross member 4 as described above, when both ends of the metal rod 10 are twisted, the welded fixation portion approximately at the central portion will be welded. Although there is a possibility that a strong force is directly applied and the welded part comes off when used for a long period of time, problems such as the welding part coming off may occur. When it is fixed to the floor member 1 side, the force applied to the fixed portion is reduced, a complete fixing effect can be obtained, and durability is improved.

In the present invention having the above configuration, when the end panel 2 is in an upright state, both ends of the metal rod 10 are fixed to the end panel 2 side, and the approximately central part thereof is fixed to the floor member 1 side. When the end panel 2 is folded onto the floor member 1, both sides of the metal bar 10 are gradually rotated and twisted, applying a brake to the end panel 2, which causes the end panel 2 to come into contact with the floor member 1. It works the strongest when it comes in contact with the floor member 1 or the end panel 2, unlike conventional methods, and can be folded slowly with a small force, without pinching hands or feet, etc. 1. Even if the limbs are pinched, there will be no serious injury.

Furthermore, when the end panel 2 is erected, the metal rod 10
Due to the restoring force, only a small force is required, making it extremely easy to handle.Furthermore, the metal rod described above can also serve as a pin and be built into the floor member, making it easy to manufacture and stylish.

Furthermore, unlike the use of coil springs, etc., it does not cause failures and has the effect of improving durability.
