Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to footwear, and more particularly to footwear suitable for safety shoes, work shoes, and the like having multiple functions such as a stepping function and a conductive function.

[0002]

[Prior art]

Safety shoes worn when working in an electrical environment, for example, when using electrical or electronic equipment, have a specific range, for example, 1.0 × 10 ⁵ ≦ R ≦ 1.0 × 10 ⁹ Ω. There are JIS standards that require electric conduction resistance or leakage resistance. Such safety boots must have the ability to protect against harmful electrical shock when touched by charged devices and, on the other hand, to provide some charge leakage. If the sole configuration has a very high electrical leakage resistance, so that the sole configuration is effectively an insulator, the sole configuration will use the human body wearing safety shoes as one electrode, The floor on which the person stands is used as the dielectric of the capacitor with the other electrode. When the person touches a charged device, the capacitor becomes charged. Failure to eliminate this charge can cause problems or damage to electronic devices touched by a charged person, and such charging can have harmful effects on the human body. Therefore, the electrical leakage resistance of the sole configuration must not exceed a certain maximum resistance value so that this charging can be eliminated within a reasonable time.

[0003] Against this background, safety shoes having a sole made of polyurethane (PU) made conductive by adding conductive particles, for example, carbon particles or graphite particles, have already been developed. When these safety shoes are worn, after the human body is charged, the charge can be reliably released from the human body. On the other hand, it is known that safety shoes are provided with a step-out prevention plate on the soles thereof in order to prevent a nail or the like from stepping over. However, none of the current safety shoes has an effective shock absorbing property in addition to the above-mentioned conductive function and step-through prevention function. In addition, none of the winter protection shoes have the functions of leading core, cold protection, antistatic, anti-stepping-over, and shock absorption functions, which are insufficient for workers in cold regions in terms of safety and comfort. There was a point.

[0004]

[Problems to be solved by the invention]

 Therefore, the present invention has a structure that provides protection against cold in footwear with a toe tip, a structure that allows static electricity charged to the user to escape, and a foot protection that protects the foot from protrusions such as nails. An object of the present invention is to solve the above-mentioned problems of the conventional footwear by providing a footwear having a board and an airbag at the bottom for absorbing a shock. In the footwear according to the present invention, by using a bore in the lining of the winterization shoes, it is possible to make the footwear warm and resistant to stuffiness with excellent moisture retention, moisture absorption and drying properties. In addition, by providing an antistatic function, it is possible to prevent an accident at a work site such as ignition due to static electricity. Furthermore, using synthetic leather for footwear, it is designed as a sporty sneaker-type work shoe, a steel toe at the toe, a step-out prevention plate integrated with the insole, a shock absorbing air bag at the heel, etc. With these multi-functional footwear, footwear with excellent safety, usability and design can be obtained.

[0005]

[Means for Solving the Problems]

 For this reason, the technical solution adopted by the present invention is a footwear having a toe with a toe core, having a structure having a cold protection property, a structure for discharging static electricity charged to a footwear user to the outside of the shoe, and a nail or the like. The footwear has a composite function characterized by having a step-out prevention plate for protecting the foot from the protrusions and an airbag at the heel for absorbing shock. An insole composed of a non-conductive bore, an insole cushion, and a conductive step-prevention plate and provided with a conductor that electrically connects the bore surface and the step-out prevention plate, and provided on the step-out prevention plate A conductive body, a conductive insole, a non-conductive midsole provided with an airbag in the heel, and a conductive outsole, wherein the midsole is electrically connected to the conductive insole and the conductive outsole. The present invention provides footwear having a composite function in which electrically conductive conductors are arranged. Further, the conductor is a footwear having a composite function, wherein the footwear is made of a conductive cloth. The shoe is a work shoe characterized by being formed using synthetic leather.

The insole 1 is composed of a non-conductive bore 2, an insole cushion 3, and a step-out prevention plate 4, as shown in FIG. On the side, as shown in FIGS. 1 and 3, a conductor 6 for electrically connecting the surface of the bore 2 and the anti-stepping-off plate 4 is disposed to release static electricity charged on the human body toward the sole of the shoe. Have been. The insole 1 is detachably arranged in the shoe so that the bore 2 side is inside the shoe. The step-out prevention plate 4 has a function of preventing the protrusion from entering the shoe when the protrusion such as a nail is stepped on, and is made of a conductive material (metal or the like). Reference numeral 5 denotes a conductor (conductive cloth in this example) attached to the outside (shoe sole side) of the step-out prevention plate, and reference numeral 7 denotes a conductive midsole.

In the drawing, the conductive cloth 6 is provided on a part of the step-out preventing plate, but the conductive cloth 5 can be disposed on the entire surface of the step-out preventing plate 4.
