TWM656804U - Antistatic shoes - Google Patents

Abstract

An anti-static shoe includes a midsole and an upper. The midsole includes a sole and an insole connected to each other, both of which contain conductive materials that can electrically connect the ground and the sole of the wearer's foot. The sole has an anti-slip structure; the insole has an anti-slip portion and a concave portion. The upper and the insole are connected to form the wearing space together. When the wearer walks or stands in contact with the ground, the accumulated charge of the wearer's body will be transferred from the sole of the foot to the ground through the midsole. This prevents the static electricity phenomenon caused by the accumulation of body charge.

Description

Anti-static shoes

This creation is about a pair of shoes, especially anti-static shoes with good electrical conductivity.

Static electricity is a physical phenomenon that occurs widely in our daily lives. Objects transfer charges through contact, friction or collision to form different electrical layers. If the charge is distributed between two insulating objects, when the objects are separated, the two objects become positively charged and negatively charged, respectively. When the voltage is large enough due to the continuous accumulation of positive or negative charges, it will break through the insulating medium (air, insulating layer) to produce electrostatic discharge. In daily life, static electricity mostly only causes a tingling sensation, but in industry it may cause harm due to sparks, especially in industries related to electronic component assembly. The heat generated by static electricity may burn the circuit, damage the insulation or damage the components.

In order to avoid electrostatic discharge, in addition to reducing the main causes of uneven electron distribution such as large-area contact, friction or collision, another countermeasure is to avoid charge accumulation. Generally, static eliminators are used to eliminate the accumulated charge on the human body, or anti-static wrist straps are used to connect the human body to the ground to avoid charge accumulation. However, in fact, the human body itself is a good conductor, but for safety reasons, it is necessary to wear shoes at work, which makes it easy to accumulate charges due to insulation from the ground. The fundamental reason for static electricity is that the outside world or the ground is separated from the human body by an insulator, so that the charge cannot be effectively discharged and balanced. However, in order to be durable or non-slip, shoes often use insulators such as rubber or polymer compounds, which cannot effectively discharge the charge from the human body.

The creator of this case, in view of the fact that shoes are poor conductors and will hinder the conduction of charges to the outside world, has actively and continuously improved the creation to solve the above problem while facilitating the wearer's activities.

This invention mainly provides an anti-static shoe with a good conductive structure, which can conduct the excess charge accumulated in the human body to the ground or the outside world, avoiding the harm caused by electrostatic discharge generated by the accumulation of charge in the human body.

The anti-static shoes of this invention include: a midsole and an upper. In addition, the midsole is close to the wearer's toes as the front side, and close to the wearer's heel as the rear side. The midsole includes a sole and an insole that are connected to each other, both of which contain conductive materials that can electrically connect the ground and the wearer's sole, and the sole is the contact surface between the midsole and the ground, and has an anti-slip structure; the insole is the contact surface between the midsole and the wearer's sole, and has an anti-slip portion and a concave portion. At the same time, the insole is connected to the upper to form a wearing space together.

In one embodiment of the present invention, the conductive material may be conductive carbon black or an electrostatic agent, or may include conductive carbon black and an electrostatic agent.

In one embodiment of the invention, the anti-slip structure has a first pattern and a second pattern. The first pattern is located on the front side of the sole and is in a grid shape to increase grip; the second pattern is located on the rear side of the sole and is in a groove shape to assist drainage and anti-slip.

In one embodiment of the invention, the anti-slip portion is disposed on the front side of the insole, protruding from the surface of the insole, and can be inserted into the concave portion between the wearer's toes and the forefoot to increase the force application point, thereby preventing the relative sliding of the foot and the anti-static shoe; the concave portion is disposed on the surface of the insole, which can increase the comfort and stability of the wearer's foot.

One embodiment of this creation can be a pair of slippers, boots and long boots formed in one piece.

One embodiment of the invention can be made of polyvinyl chloride (PVC), polyurethane (PU), thermoplastic rubber (TPR) or ethylene vinyl acetate (EVA).

In summary, the anti-static shoes of this invention utilize the characteristics of the human body as a good conductor. The conductive structure of the shoes is designed to increase the electrical circuit between the human body, the shoes and the ground, so that the accumulated charge can be directly conducted into the ground without accumulation, thereby avoiding the occurrence of static electricity.

Figures 1 to 5 are schematic diagrams of the appearance and structure of the present invention. As shown in Figure 1, the anti-static shoes of the present invention include: a midsole 1 and an upper 2. The midsole 1 includes a sole 11 and an insole 12 connected to each other, both of which contain conductive materials that can electrically connect the ground and the wearer's sole. The sole 11 has an anti-slip structure 111, and as shown in Figure 2, the anti-slip structure 111 has a first pattern 1111 and a second pattern 1112; the insole 12 has an anti-slip portion 121 and a concave portion 122. At the same time, the upper 2 and the insole 12 are connected to form a wearing space for the wearer to wear.

In a preferred implementation of the invention, the wearer inserts his feet into the wearable space. When walking, the accumulated charge of the body is conducted to the ground through the soles of the feet and the midsole 1, thereby avoiding static electricity caused by the accumulation of body charge.

In a preferred embodiment of the invention, the conductive material is conductive carbon black or electrostatic agent, or it may contain conductive carbon black and electrostatic agent at the same time, which can further reduce the resistance of the anti-static shoes of the invention and can more effectively transfer the charge to the ground. For example, the conductive carbon black or electrostatic agent can be processed into powder or liquid and then added to the material for making the sole 11 and the insole 12, and then molded.

In a preferred embodiment of the present invention, the first pattern 1111 is disposed on the front side of the sole 11 and is a grid-shaped groove that can increase the grip, and the second pattern 1112 is disposed on the rear side of the sole 11 and is a groove-shaped groove that assists in drainage and anti-slip.

In a preferred embodiment of the invention, the anti-slip portion 121 is disposed on the front side of the insole 12, and is in the shape of a tripod and protrudes from the surface of the insole 12, and can match the groove between the wearer's toes and the forefoot, thereby increasing the force application point to prevent the anti-static shoes of the invention from sliding against the wearer's sole. The concave portion 122 is disposed on the surface of the insole, which can increase the comfort and stability of the wearer's foot.

A preferred embodiment of the invention can be a pair of slippers, boots and long boots formed in one piece.

In a preferred embodiment of the present invention, the material can be made of polyvinyl chloride (PVC), polyurethane (PU), thermoplastic rubber (TPR) or ethylene vinyl acetate (EVA).
