The present application relates to containers, and, more particularly to cargo containers.
During a production process, a production workshop requires transport of a variety of raw materials, semi-finished products and finished products, and therefore would use warehouse carts and transport containers to move them. Most existing transport containers have an iron structure, which is complex to produce and has a high cost. They are also heavy, cumbersome, and occupy a large space when not in use.
As a result, there is a need for a transport container that is lightweight, has a simple structure, is easy to manufacture, and has a small footprint but large cargo space.
The instant disclosure describes a folding cargo container which addresses the defects of a transport container according to the prior art.
One aspect involves a folding cargo container, comprising a left frame, a right frame, a rear frame, a bottom frame, a cross bar, a first connection member, a second connection member, and a third connection member, the left frame is foldably connected to the rear frame via the first connection member, the right frame is foldably connected to the rear frame via the second connection member, the left end of the bottom frame is foldably connected to the left frame via the third connection member, one end of the bottom frame is formed to connect with locking slots, the locking slots lock the bottom frame to the rail on the bottom of the right frame, the left end of the cross bar is rotatably connected to the left frame, the right end of the cross bar is provided with a latching slot, and the right frame is provided with a latching pin for engagement with the latching slot.
With another aspect, the first connection member, the second connection member, and the third connection member of the cargo container are hinges.
Yet another aspect of the cargo container involves a top frame, and the top frame is foldably connected to the left frame or the right frame.
Furthermore, with another alternative aspect, the left end of the cross bar is rotatably connected to a front vertical rod of the left frame, and the latching pin is disposed on the front vertical rod of the right frame.
The present disclosed embodiments have the following advantages. Cargo containers, as described herein, that comprise a left frame, a right frame, a rear frame, a bottom frame, a cross bar, and first, second, and third connection members, have a structure that is simple, and has low production cost.
Additionally, since the bottom frame may be folded to the left frame by rotating by 90 degrees via the third connection member, the left frame may be folded to the rear frame by rotating by 90 degrees via the first connection member, and the right frame may be folded to the rear frame by rotating by 90 degrees via the second connection member, the cargo container may be folded when not in use to occupy a small space.
Moreover, embodiments of the claimed cargo container may be entirely made of aluminum alloy to be lightweight.
The foregoing and following outlines rather generally the features and technical advantages of one or more embodiments of this disclosure in order that the following detailed description may be better understood. Additional features and advantages of this disclosure will be described hereinafter, which may form the subject of the claims of this application.
As shown, the right end of the bottom frame 4 is formed to connect with locking slots 41, that lock the bottom frame 4 to the rail 21 on the bottom of the right frame.
The left end of the cross bar 5 is rotatably connected to the left frame 1. The right end of the cross bar 5 is provided with a latching slot 9, and the right frame 2 is provided with a latching pin 10 for engagement with the latching slot 9.
The embodiment of
As shown, the cross bar 5 of
In addition, the bottom frame 4 may be folded to the left frame 1 by rotating by 90 degrees via the third connection member 8. Likewise, the left frame 1 may be folded to the rear frame 3 by rotating by 90 degrees via the first connection member 6, and, in similar fashion, the right frame 2 may be folded to the rear frame 3 by rotating by 90 degrees via the second connection member 7. As a result, the cargo container may be folded when not in use, which takes up less space.
As shown, the foldable connection is between the left end of the bottom frame 4 and the left frame 1 via the third connection member 8. In an alternative embodiment, the bottom frame 4 may use the right end of the bottom frame 4 for foldable connection to the right frame 2 via the third connection member 8, which can also achieve the same folding effect, which is a mirror image of
With some implementations, the left frame 1, the right frame 2, the rear frame 3, and the bottom frame 4 may be an aluminum alloy. Likewise, the cross bar 5 may be an aluminum alloy rod. This is because aluminum alloy has high strength, light weight and is simple to manufacture. Naturally, a user may also select other materials, as long as they meet the requirements of high strength and lightweight.
In the embodiment of
In some embodiments, the folding cargo container may further comprise a top frame (not shown) that is connected in a similar manner to either the left frame 1 or right frame 2 such that the top frame can be foldably connected to the left frame 1 or the right frame 2 depending upon the hinge location.
Finally, as shown in
