Benefits of technology
[0026]Since safety footwear is included therein, they may have steel toecups to prevent toe damage caused by industrial labors.
[0028]The development includes a body triboelectric unloading device, built of semiconductor or conductive rubber, combined with a insole with a part or the whole surface built of the same material as the unloading device, keeping in constant contact the person and the unloading device, which placed in any footwear contacts the body with the ground in hundredths of seconds, with the additional advantage that if accidentally the person contacts the 220 Volt or 110 Volt power line, the leak current is below the body tolerance limit. This unloading device does not only enable modifications of any footwear, it also guarantees a better health, just by transforming a common footwear into a CONDUCTIVE, RESISTIVE AND ANTI-TRIBOELECTRIC FOOTWEAR.
[0033]The unloading devices comprise pin-shaped elements having a long body between 1 mm and 8 mm in diameter and a head of diameter varying between 4 mm and 15 mm. Larger dimensions may be used to increase the contact area between the unloading device and the conductive resistive insole.
[0038]The unloading device is inserted, passing from the assembly insole to below the bottom for contacting the floor, eliminating the excessive portion of unloading device passing underneath through the portion contacting the floor manufactured of the same material as the unloading device. Said unloading device may be placed in any part of the footwear, as long as it has the above-described shape, preferably in the heel area.
Problems solved by technology
But triboelectric problems act as ghosts.
Usually it is generally unknown to attribute the accident to triboelectric problems, and since there is no adequate diagnosis, no correct action is instituted.
Lack of acknowledgement of this issue may have severe consequences in the field of personal safety, because the so-called electrostatic problems, in fact triboelectric in origin (that is, displacement of electric charged by friction), are carelessly treated.
European publication EP 0791302 A1 refers to a footwear with electrostatic protection providing a footwear which eliminates the accumulation of electrically static charges generated on the body or clothing by ground unloading or the floor using a unloading material provided by the sole, in this case there is no safe protection against accidental contact with a 110 Volt to 220 Volt power line.
Patent publication WO 2008058984 A1 relates to a footwear with an electrically conductive sole and at least one electrode contact within the shoe, which is electrically connected to the sole; this type of footwear may have a permanent magnet in the middle of the sole to provide improvement of the health status, in this case there is no safe protection against accidental contact with a 110 Volt to 220 Volt power line.

example 1
[0047]A body or cut of any footwear model type was assembled on a conventional insole; a chemical sole is injected, either of a polyurethane rubber polymer, leather sole, PVC, TR, where the portion contacting the floor always contains the resistive conductive component in a suitable cast forming the footwear bottom or sole.
[0048]The insole is perforated from top to bottom in the heel area jointly with the bottom of the footwear, the unloading device is introduced with the shape of a pin with a 1 cm head and a 6 mm body, where the head leans on the conventional insole.
[0049]A resistive conductive insole is manufactured with the same material as the unloading device, with the same shape as the conventional insole and a shape adequate to introduce it in the footwear body so it contacts the head of the unloading device. The obtained footwear has an electric resistance of 250,000 to 1,000,000 Ohm to the whole body or 500,000 to 2,000,000 for each shoe.
example 2
[0050]A footware bottom was made by sole and heel manufactured in rubber comprising natural rubber with conductive lampblack in a percentage between 30 to 40% w / w, that is the resistive conductive component. The footwear cut or body was annealed on the conventional sole, which was glued and annealed on the manufactured bottom.
[0051]The front part of the sole is perforated from top to bottom and the unloading device shaped as a pin of the same size as example 1 is introduced so its head leans on the conventional insole.
[0052]A resistive conductive semisole, made of rubber based on natural rubber and conductive lampblack in a percentage between 30 to 40% w / w is added, with a shape of about half of the conventional insole, in such a way that it contacts the head of the unloading device.
[0053]The obtained footwear has an electric resistance between 250,000 to 1,000,000 Ohm to the whole body or 500,000 to 2,000,000 for each shoe.
example 3
[0054]It was performed like example 1 but in this case 2 unloading devices were added, one in the heel area and the other on the front part.
[0055]The obtained footwear has an electric resistance between 250,000 and 1,000,000 Ohm to whole body or 500,000 to 2,000,000 for each shoe.

Abstract
The present application refers to a conductive, resistive and anti-triboelectric footwear comprising a footwear body or cut, a semiconductor sole, a resistive conductive insole, a common insole, a bottom of sole having contacting the floor made of the same material as the unloading devices and the semiconductor insole and unloading devices, with the purpose of contacting the human body with the ground and achieve the release of the stored static electricity on which the footwear body is fixed, characterized in that the unloading devices pass through the common insole and the footwear bottom making contact between the resistive conductive insole and the ground at least through the portion or the whole sole when it is resistive conductive; and its manufacturing method.
Description
FIELD OF THE INVENTION[0001]The present invention, as expressed in the disclosure of this specification, refers to conductive, resistive anti-triboelectric footwear for the general public having daily problems with accumulation of electrical charges, and at the same time is protected against possible electric discharges produced by the contact with electric equipments connected to local power networks.[0002]This footwear model is also for physicians, nurses and / or any health staff members, wherein fatal accidents have been reported, caused by static electricity accumulated in the body and unloaded on patients in surgery rooms, coronary units, or intensive care units; also in refrigerated industrial meat processes, dairy industries, supermarkets, where white footwear is required for hygienic reasons.[0003]The main advantage of conductive, resistive anti-triboelectric footwear is that the user may unload static electricity stored in the body and at the same time be protected against a...
