Description

DETAILED DESCRIPTION OF THE INVENTION This invention is applicable to, for example, meat processing operations using sharp knives;
The present invention relates to protective gloves used to protect the hands of workers during dangerous operations such as glass manufacturing operations that involve sheet glass, etc., and sheet metal forming operations that involve handling the edges of sheet metal.

As protective gloves used to protect the hands of workers during dangerous work, those disclosed in Japanese Utility Model Application No. 47-28] and No. 25 are known.

The protective gloves disclosed in Japanese Utility Model Application Publication No. 47-28125 are made of highly flexible metal wire.

The metal wire is made of twisted stainless steel wire or a single wire, and the weave is stockinette.

Since these protective gloves are made of metal wire, they can protect the hands of workers during dangerous work.

However, since these conventional protective gloves are made entirely of metal wire, they are slippery during work, have poor graspability, and are heavy.

For this reason, these conventional protective gloves have the drawback of poor workability and heavy labor burden on the operator.

This invention was made in order to eliminate the drawbacks of the conventional protective gloves mentioned above.It improves the grip and graspability, reduces the weight as much as possible, improves the work efficiency of the worker, and reduces the labor burden. The purpose of the present invention is to provide protective gloves designed to protect the wearer.

That is, the present invention is made of a composite yarn composed of a core and a sheath, the core is composed of a flexible wire and an aramid core, the aramid core is composed of aramid fiber strands, and the wire and the aramid core are arranged in close contact with each other, and the outer sheath is composed of a pair of aramid outer sheaths, each of the pair of aramid outer sheaths is composed of aramid fiber strands,
Each aramid jacket of the jacket consists of a protective glove which is spirally wrapped around the core in mutually opposite directions.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows an embodiment of the protective glove according to the present invention.

In the figure, 10 is a protective glove, which includes a thumb sac 16, a finger sac 14 for fingers other than the thumb, and a character part 18.
, has a back part 20 and a wrist area 22.

The protective glove 10 is made from a composite yarn 12 as shown in FIG.

The composite yarn 12 is composed of a core 23 and a sheath 29.

The core 23 includes a flexible wire 24 and an aramid core 2.
It consists of 5.

The wire 24 is made of stainless steel, malleable iron, copper, aluminum, or other flexible metal, and is annealed.

The diameter of the wire 24 is 0, ], 01.6~0.1542
±0.mm (0.004” to 0.006”). O
1,27 baskets (0,0005"), no minimum, maximum 0.2
The b aramid core 25, which is in the range of 54 mm (0.01"), consists of a strand of aramid fiber.

Here, the aramid fiber is “Kevlar” (Kevl).
E.I. DuPont (E.I. DuPont, Illumington, Praue State, U.S.A.) under the trademark ER).

1, DuPont) is a commercially available fiber.

Also, the term strand (5 strand) refers to a slightly thick linear object, whether or not it is twisted.

The aramid core 25 is made of spun thread-like aramid fibers or filament-like aramid fibers.

When spun yarn aramid fiber is used as the aramid core 25, the spun yarn has a cotton count of 1 to 60, preferably 15 to 35, more preferably 25.
You can use one with a thickness of just a few inches.

Aramid core 25 is a filament-like aramid fiber.
When used as
00 denier, preferably 200 to 400 denier can be used.

Aramid core 25 is a filament-like aramid fiber.
The aramid core 25 when used as a wire is substantially untwisted.

The wire 24 and the aramid core 25 are arranged in close contact with each other.

The jacket 29 consists of a pair of aramid jackets 26,28;
This pair of aramid outer sheaths 26.28 are 2 bows h2 go candy-7gu・so kyo can board meeting 1"fu gunship → ゛ノ Vφ, 1
- Here, the aramid jacket 26, 28 consists of spun thread-like aramid fibers or filament-like aramid fibers.

Spun thread-like aramid fibers form an aramid jacket 26.2
When used as spun yarn, a spun yarn having a thickness of 1 to 60 counts, preferably 15 to 35 counts, and more preferably 25 counts can be used.

Filament-like aramid fibers form aramid jacket 26
．． When used as 28, the filament is 200~
A thickness of 1500 denier, preferably 200 to 400 denier can be used.

Incidentally, as the aramid jacket 26, 28, spun thread-like aramid fiber is preferable.

Each aramid sheath 26, 28 of the sheath 29 is wrapped around a core 23 consisting of a wire 24 and an aramid core 25.

At this time, one aramid outer sheath 26 and the other aramid outer sheath 28 are spirally wound in opposite directions.

The protective glove 10 is manufactured by applying the above-described composite yarn 12 to a normal glove knitting machine.

As explained above, the present invention is made of a composite yarn composed of a core and a sheath, the core is made of a flexible wire and an aramid core, and the aramid core is made of aramid fiber strands. Since the outer jacket is composed of two aramid outer jackets and the aramid outer jacket is composed of aramid fiber strands, the flexibility of the protective gloves is improved, and the grip and grip properties thereof are improved, and the workability is improved. Get better.

Therefore, together with the reduction in weight, there is an effect that the labor burden on the worker is reduced.

In addition, in this invention, the wire and the aramid core are lined up, wrapped around a pair of aramid outer sheaths, and are in close contact with each other, so the friction between the wire and the aramid core gives the protective glove an appropriate amount of plasticity, which makes it easier to grip the protective glove. This has the effect of improving ease of handling, grasping, and workability.

Furthermore, since each aramid outer sheath of the outer sheath is spirally wound around the core in opposite directions, the outer sheath will not loosen even when bent in any direction, and the surface of the composite yarn will not become uneven. This has the effect that a suitable cushion is generated between the composite yarns, the surface of the protective glove is prevented from slipping, the gripability and graspability of the protective glove are improved, and workability is therefore improved.

Further advantages of the gloves of the present invention over conventional wire mesh or ring gloves include strength, resistance to breakage, resistance to moisture absorption, non-irritation of the skin, lightweight properties, flexibility, rewashability, and insulation. It lies in the improvement of characteristics.

The gloves of the present invention are safer because the gloves of the present invention will slip off the hand when grabbed by some exercise machines, whereas conventional mesh gloves will buckle in place and will not slip off.

The gloves of the present invention are elastic so that they fit well in the hand, and their flexibility provides a good feel and makes it easier to securely grip workpieces, tools, etc.

The gloves of the present invention are more comfortable and can be used on either hand, whereas the metal mesh gloves can be used on either the left or right hand.

The gloves of the present invention can be used for both cold protection and heat protection.
Approximately 56.7 gr (2oz) compared to the weight of 4oz)
It has the notable advantage of being lightweight.

Although the non-inventive gloves can also be sterilized when used for food handling and are easily made with modern machines, metal link gloves are usually hand-made from link sheets.

Advantages of the protective gloves of the present invention over conventional protective gloves include better mechanical manipulation of the threads, greater resistance to tip penetration as the knitted or woven stitches do not stretch as much when stressed, and greater resistance to tip penetration when stressed. The purpose of this is to improve cutting resistance by preventing excessive stress from being applied to the aramid fibers on the finger joints.
