Abstract

PURPOSE: To perform a work safely and comfortably even under severe condition with safety boots which protect feet from oil, water, chemicals, etc., and is equipped with hard toe cores, and is comfortable to wear, too, concerning the safety boots with built-in hard toe cores which protect oil, water, cement, chemicals, etc., from penetrating into them through the instep of boots, the seams, etc. CONSTITUTION: Both sides of nylon cloth 1 high in incision resistance are coated in thickness of 0.5mm or under with a synthetic rubber 2 excellent in oil and chemical resistances, and this is joined directly as a instep leather 3 with a bottom 5 of a booth. This boot has high level of waterproofness, incision resistance, and oil and chemical resistances at the same time by waterproofing a stitch part of instep leather 3 with waterproof cloth 7 and waterproof liquid, and junction between the instep leather 3 and the bottom 5 with waterproof liquid. Furthermore, this is a boot with a built-in hard toe core which can fulfill the comfortableness to wear and the comfortableness to walk, all of these at the same time, by the instep leather 3 having fitting feeling, with the three- layer structure consisting of the nylon cloth and the two layers of the synthetic rubber of 0.5mm or under.

Description

Detailed Description of the Invention

[0001]

[Industrial application] The present invention is waterproof, oil resistant, chemical resistant,
The present invention relates to a safety shoe that has excellent cut resistance, is comfortable to wear, and is easy to walk.

[0002]

2. Description of the Related Art Various shoes are worn in a metal working factory, a pulp factory, a cement product factory, a ceramics factory, etc. in a workplace where powders of cutting oil, water, cement, chemicals and the like are scattered. Conventionally, various types of shoes have been worn, but usually rubber boots, rubber boots with hard toecaps, or leather safety boots with urethane resin coated on the sutures. It is worn with an impermeable resin or with a special vinyl upper with synthetic resin liquid applied to the seams.

[0003]

Rubber boots have safety problems in that they are not fitted with hard toecaps and are so weak that they are cut off. The rubber boots have a problem that they are unbearably worn for a long time because they are so weak that they do not have a fit. In addition, many of the safety shoes made of ready-made water-proof, oil-proof and chemical-resistant leather and special vinyl have low waterproof performance. Therefore, there is a demand for waterproof safety shoes that are completely waterproof, have a fit, and are comfortable to wear.

[0004]

According to the present invention, both sides of a nylon fabric 1 are covered with a toecap 4 made of a hard material with an upper 3 of a nylon fabric 1 coated with synthetic rubber 2.
The waterproof safety shoes are directly joined to the sole 5. The synthetic rubber coated on the nylon material has a thickness of 0.5 mm or less on both sides.

[0005]

According to the present invention, a completely waterproof safety shoe can be obtained by directly using the upper of a shoe with nylon cloth coated on both sides with synthetic rubber and directly joining it to the sole of the shoe. For synthetic rubber, use a compound that has excellent oil and chemical resistance. And, even though it is a weak point of rubber boots, it has a three-layer structure of synthetic rubber, nylon cloth, and synthetic rubber, even if the synthetic rubber of the first layer is damaged. It is difficult for scratches to reach the synthetic rubber of the third layer. The rubber boots and safety boots are also sufficiently satisfactory in terms of comfort and walking. The present invention, for the upper, using nylon fabric coated on both sides with synthetic rubber, and by attaching the sole by direct joining, complete waterproofness, cut resistance, good comfort, You can get easy walking.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment will be described with reference to the drawing shown in FIG. After sewing the heel of the upper 3 made of nylon fabric 1 coated with 0.5 mm thick synthetic rubber 2 on both sides, sew the leather 6 that reinforces the stitching of the heel, and a special composition on the thread line. A resin-based adhesive liquid is applied as the waterproof liquid 8. Further, from the inside of the heel portion of the upper 3, a cotton cloth coated with synthetic resin glue is attached as the waterproof cloth 7. The shoe sole 5 made of a hard material and covered with the toecap 4 and suspended is directly joined to the shoe sole 5, and the upper 3 and the shoe sole 5 are further joined.
A waterproof liquid 8 made of a special synthetic resin-based adhesive liquid was applied to the joint surface of, to complete a waterproof safety shoe. As a result of wearing the test shoes, they were comfortable to wear and had a completely waterproof function.

[0007]

[Effects of the Invention] The safety shoes of the present invention, which are made of leather with both sides of nylon cloth coated with synthetic rubber, have soles that are joined together by direct bonding with no gaps, and are completely waterproof and resistant to oil and chemicals. -Has excellent performance in cut resistance, comfort and walkability. In order to satisfy the wear comfort and fit, it is effective that the synthetic rubber to be coated is as thin as possible, but the strength deteriorates in inverse proportion. To satisfy both comfort and strength, 0.
Two layers of synthetic rubber of 5 mm or less were stacked, and a nylon fabric was sandwiched between them to form a three-layer structure. Even if the synthetic rubber of the first layer is rubbed or cut, the nylon fabric of the second layer softens or prevents the damage, making it difficult for the scratch to reach the synthetic rubber of the third layer, Does not impair the waterproof effect. In addition, the upper made of thin synthetic rubber of 0.5 mm or less and supple nylon fabric conforms well to the wooden mold, so it has good formability, fits well on the foot, and has excellent flexibility when walking. There is.
