Description

[Detailed description of the invention] This invention relates to an opening/closing chuck used for a net for loading agricultural products, etc.

Conventionally, when unloading agricultural products and marine products, there have been mesh-shaped loading bags that are convenient for transporting and unloading agricultural products and marine products that are covered in mud and sand.

When such loading bags are used, they are hoisted up by a crane or the like and transported to a predetermined location, where the bottom of the bag is lifted upwards, turned over, and agricultural products, etc. (e.g. potatoes) are discharged from the net.

However, when turning over, agricultural products are likely to be damaged, and it is often dangerous.

Therefore, we thought that if we provided an opening/closing part on the bottom of the net-shaped loading bag, it would be possible to safely discharge the agricultural products, etc. without inverting the bag at a predetermined position. I tried adding a flexible zipper.

However, in reality, it was found that the fasteners were difficult to open and close due to mud, sand, etc. adhering to agricultural products, etc., and there were also problems in terms of strength.

Therefore, the purpose of this invention is to provide an opening/closing chuck that functions as a zipper, is stronger than a zipper, and does not cause clogging, and is mainly used for mesh-like cargo bags.

The chuck of this invention is made by placing inverted U-shaped chucks facing each other at equal intervals on each of two reinforcing members stretched parallel to the bottom of the loading bag, and overlapping the opposing chucks. The feature is that a pull-out member is removably inserted into the circular space, and an embodiment in which the pull-out member is used in a net-like loading bag will be described based on the drawings. The mesh loading bag 1, which can load a large amount of vegetables, etc. (for example, potatoes) with the top still attached, is a net bag having a substantially regular cubic shape, and the upper part 1a is open so that agricultural products, etc. can be thrown in. A hanger 2 for lifting is provided at a corner of the plane of the upper portion 1a.

On the other hand, the bottom surface 1b of the net-like cargo bag 1 is provided with a chuck portion 3 that can open the bottom surface 1b.

FIG. 2 shows an enlarged view of this chuck part 3.
As shown in FIG. 2, two reinforcing ropes 4 are arranged near the center of the bottom surface 1b of the net-like cargo bag 1, substantially parallel to one end edge of the bottom surface 1b, and each of the reinforcing ropes 4 is Inverted U-shaped rope chucks 5 are provided facing each other at approximately equal intervals.

Then, a circular space C created by overlapping the chucks 5
A pull-out rope 6 is inserted through.

One end of this pull-out rope 6 is fixed to the loading bag, and the other end is a free end.

The chuck part 3 consists of a reinforcing rope 4, a chuck 5, and a pulling rope 6.

Note that both ends of the reinforcing rope 4 may be connected to each other,
They do not need to be combined.

In the latter case, the opening will be wider when opened.

Further, the reinforcing rope 4 may be stretched diagonally on the bottom surface 1b.

Further, the distance between the chucks 5 can be made wider or narrower depending on the required strength.

The material of the chuck portion 3 may be the same as the net of the net-like cargo bag 1, or may be of a different material.

However, considering the pull-out resistance of the pull-out rope 6, polyethylene monofilament-based material is preferable.

Also, bars may be used instead of the reinforcing rope and the pulling rope.

The chuck may be made of metal.

In the above embodiment, after agricultural products are loaded onto the net-like loading bag 1 and transported to a predetermined location by a crane or the like, when the pull-out rope 6 is pulled out from the fixed end of the pull-out rope 6, the chucks 5 that have been overlapped are pulled out. The tip becomes a free end and opens due to the weight of the produce.

After all the produce has fallen due to its own weight, chuck 5 again.
are overlapped, and the pull-out rope 6 is inserted into the circular space C to be formed and returned to its original position.

Figure 3 shows the state in which it is opened due to the weight of agricultural products, etc.

As explained in the above embodiment, this invention provides two reinforcing members stretched in parallel with inverted U-shaped chucks facing each other at approximately equal intervals, and stacks the opposing chucks. This is a chuck member for loading bags, which is characterized by a pull-out member inserted and removed through the circular space created by the combination.It has a simple structure, high strength, and can be made of cloth or mesh. If it is used not only for loading bags such as but also for the bottom of general bags, it is possible to obtain an opening through which loaded items can be dropped with a single touch.

Also, it does not get clogged with soil etc.

In this way, it has extremely high practical value.
