Description

[Detailed Description of the Invention] The present invention relates to a fiber sling with a wire mesh inserted therein for reinforcement.

As is well known, fiber slings are used in large numbers because they are flexible, strong, light, and extremely easy to handle without damaging the articles being hung.

However, since textile slings are a textile material and there is a risk of cutting when hanging articles with sharp edges, protective corners must be attached to the body of the textile sling.

Even if such a protective corner is provided, there is a risk that the sharp corner will cut the protective corner and the fiber sling body if, for example, the lifted article is improperly hung and tilts or slides sideways.

Therefore, the present applicant proposed a technique in which a metal wire is interposed inside such a protective corner.

However, even if such a protective corner is used, there is a drawback that the suspended load may come into contact with the protective corner in a place where there is no protective corner, or the protective corner may fall off during the lifting operation.

Further, it is not preferable to construct the sling with a metal body because it makes the characteristic of fiber slings, such as flexibility, chronic.

Therefore, an object of the present invention is to provide a fiber sling that does not have chronic characteristics and does not break due to unexpected circumstances.

Therefore, according to the present invention, in a fiber sling made by overlapping and sewing textile belts of a predetermined width and a predetermined length, a bias-woven wire mesh is sandwiched over the entire length of the main body of the fiber sling. A textile sling is provided in which wire mesh is sewn to the belt.

In this way, in this invention, the wire mesh is sandwiched over the entire length of the main body of the fiber sling, which prevents the sling from being cut by objects with sharp corners, and the wire mesh is woven in a bias shape. Therefore, it can expand to follow the belt's expansion, and there will be no problem even if this wire mesh is sewn to the belt.

Since the wire mesh is sandwiched between the fiber belts, the flexibility of the fiber sling is not substantially impaired.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a conventionally known iron and eye type fiber sling, in which fiber belts 1 of a predetermined length are overlapped as shown in the figure, and both ends 1 a and 1 b of the flat belt have a length L. They are overlapped in the range of , and are sewn together with the main body portion indicated by length LL at the sewn portion 2, and ear portions 4a and 4b are formed on both sides.

The above are known fiber slings, but according to the present invention, the second
As shown in the figure, the following belt parts 5a constituting the main body part,
A wire mesh 3 is inserted between the belt parts 5b and sewn integrally with the belt parts 5a and 5b by the sewing part 2a shown in FIG.

Figure 3 shows how the wire mesh 3 is inserted, and the width W of the wire mesh 3 is
and the width W of the belt 1 are almost equal, and the wire mesh 3 is the main body part LL.
Seven belt portions 5a over the entire length of.

It is sandwiched between 5b.

The belt portions 5a, 5'D and the wire mesh 3 are sewn together 2a, 2b at the same time.

Wo indicates the sewing interval. By the way, in this way, the wire mesh 3 is attached to the belt portion 5a.

When sewn together with 5b, the belt 1 and the wire mesh 3 elongate differently under load, so the wire mesh 3 becomes the sewn portion 2a.

There is a risk of cutting the sewing thread 2a.

Therefore, in order to be able to follow the elongation of the belt 1 as much as possible as the wire mesh 3, lines 3a constituting the wire mesh 3 as shown in FIG.
3b uses wire mesh knitted in a bias pattern.

By using the bias-knit wire mesh 3 in this way, the wire mesh 3 follows the elongation of the belt 1, and even if the wire mesh 3 is sewn together with the belt 1, the wire mesh will not cut the sewing thread of the sewn parts 7a, 7a. There will be no inconvenience caused.

As for the wire mesh, it is preferable to use one knitted in a bias shape as described above, and the wire diameter is about 0.3 to 1.0 mm, and the material is preferably mild steel, stainless steel, or copper.

As a measure to prevent the sewn parts 2a, 2a from being cut by the wire mesh 3, the width is the distance W between the sewn parts 2a, 2a.

It is conceivable to use a wire mesh 3 narrower than the sling and not to sew it to the belt 1 so that the belt 1 can stretch regardless of the wire mesh 3, but with such a structure, the sling will not be easily sewn as the sling is used repeatedly. There is a risk that the longitudinal ends of the wire mesh 3 may break through the sewn portion 2 and come out, which is undesirable.

Furthermore, instead of inserting the wire mesh 3 over the entire length of the main body portion LL, it may be considered to insert it only in the corners of the article, but such a structure has the disadvantage that its use is limited to specific articles. .

Therefore, a bias-knit wire mesh is used as the wire mesh, the wire mesh is inserted over the entire length of the belt body, and the wire mesh is sewn to the belt.

As explained above, in the fiber sling according to the present invention, since the wire mesh is inserted over the entire length of the fiber belt main body, the sling is prevented from being cut by objects having sharp corners. Furthermore, since the wire mesh is knitted in a biased manner, it can stretch to follow the elongation of the belt, and therefore there is no problem even when the wire mesh is sewn onto the belt.

Since the wire mesh is sandwiched between the fiber belts, the flexibility of the fiber sling is not substantially impaired, and the fabric is made using commercially available wire mesh woven in a bias shape to match the width of the belt. All you need to do is cut the wire mesh into approximately equal widths, sandwich the wire mesh between the belts, and sew it together with the belt.
The cost is not significantly higher than that of conventional fiber slings made only of fiber belts.
