Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a protective net for a gas cylinder that is detachably attached to the gas cylinder.

[Prior Art] A cylinder filled with liquefied gas or compressed gas and used for storage and transportation is a cylindrical container made of steel and has a considerable weight. Therefore, they tend to be handled roughly, and their surfaces are prone to scratches and rust.

By the way, for example, semiconductor manufacturing factories, i.e. IC
In factories, garbage and dust are extremely disliked, and various treatments are carried out in clean rooms. Therefore, if the cylinders delivered to such factories are damaged, rust will form there, so some kind of countermeasure is required. However, no such measures have been taken in the past, and the reality is that workers clean the surfaces of cylinders and remove rust and the like manually when they are delivered. Therefore, it is conceivable to provide protection on the outside of the cylinder, but simply covering the cylinder with a coating means makes the heavy cylinder difficult to handle. Further, the covering means must be easily attached to and removed from the cylinder.

[Problems to be Solved] Therefore, an object of the present invention is to provide a protective net for a gas cylinder that fits suitably around the outer circumference of the gas cylinder and is easy to handle and remove.

[Means for Solving the Problems] According to the present invention, in a gas cylinder protective net that is detachably attached to a gas cylinder, a cylindrical net is formed from an outer strand and an inner strand made of synthetic resin, and the cylindrical The inner diameter of the net is smaller than the outer diameter of the gas cylinder to which the net is attached, and the outer strand and the inner strand extend at inclinations in opposite directions with respect to the axis of the gas cylinder to which the net is attached.

[Explanation of function and effect] Therefore, by simply covering the outside of the gas cylinder with the net, it is possible to protect it from impact from the outside, and the gas cylinder will not be damaged even if something hits it. Therefore, even if something hits it during handling or transportation, it will not get scratched and rust will not occur. Therefore, when the product is delivered to an IC factory or the like, cleaning work such as removing rust is not necessary, at least on the sides. Because the net is cylindrical, the bottom of the cylinder is not protected, so it is only necessary to clean the bottom.

Since the outer strand and the inner strand are inclined in opposite directions with respect to the axis of the gas cylinder, they can expand and contract in the diametrical direction, and the inner diameter of the net can be approximately 0.6 relative to the gas cylinder diameter. Can hit well.

Since it expands and contracts in the diametrical direction, it is easy to install.

[Examples] Examples of the present invention will be described below with reference to the drawings.

Now, in FIGS. 1 and 2, the net N in which the present invention is implemented is composed of an outer strand 2 and an inner strand 3, and is attached to a cylinder 4.

Outer strand 2 and inner strand 3
The net itself is well known and is made of soft synthetic resin. The entire cylinder is formed into a cylindrical shape, and its inner diameter is about 0.6 of the cylinder's outer diameter.

The inner strand 3 is in contact with the outer surface of the cylinder 4, and the outer strand 2 is located outside the inner strand so as to contact an external object.

As shown, the outer strand 2 and the inner strand 3 run in opposite directions with respect to the axis of the cylinder, that is, the outer strand 2 runs downward to the right and the inner strand 3 runs upward to the right.

Therefore, in FIG. 2, when a force is applied to the net N in the direction of arrow B, the outer strand 2 and the inner strand 3 run diagonally, so the diameter expands. Therefore, it can be easily attached to and detached from the cylinder 4. If you put it on again, you can use NetN.
Since the diameter of the cylinder is smaller than that of the cylinder 4, it fits well into the cylinder.

Figure 3 shows the cylinder 4 according to the present invention loaded in the trunk.The net N prevents the load from shifting, and the elasticity of the synthetic resin net acts as a buffer, making it easy to transport. It is also suitable for

[Effects of the invention] As described above, the invention provides the following excellent effects.

(i) Since the outer strand and the inner strand extend obliquely with respect to the axis of the gas cylinder, the net can be easily expanded and attachment/detachment work is facilitated.

(ii) For this purpose, fit the gas cylinder well.

(iii) Since the diameter of the net can be made relatively small,
Less materials required.

(iv) It is difficult to cause the load to collapse when loaded, and it is easy to transport because it has a cushioning effect.

(v) Therefore, the occurrence of rust on the cylinder surface can be prevented and handling is easy.
