Abstract

The invention is related with a shoe sole, heatable or coolable by use of electric power. Our invention has a peltier model, placed in the soles of shoes or boots at the stage of molding; a rechargeable battery or dry accumulator providing electric power required for heatinh and/or cooling; a socket to recharge the battery or dry accumulator; a switch to adjust to the desired temperature; an electronic circuit providing automatic heat and time control

Description

DESCRIPTION Heatable and Coolable Shoes Sole

The invention is related with a shoe sole equipped with an electronic circuit and power source ensuring that the peltier modules placed in shoe soles at the stage of molding are heated and/orz cooled by low electric power.

People in cold environments in winter generally tolerate cold weather conditions, if their feet get warm. Besides, they do not want their feet to sweat. For this reason, shoemakers have been in search for solutions to protect feet from cold. First, some changes have been made in designing shoes. One of such changes is to make shoe soles as thick as possible so that they could minimize the cold penetrating the sole. Another change is to coate the inner side of shoes with the materials such as woll or fiber and thus to prevent heat exchange with the environment.

However, such changes have caused shoes to become heavy and coarse. As it is known, light-weight shoes are preferable. Besides, such heavy shoes bother people in warm environments such as stores, supermarkets and hotels, athough they keep feet warm in the open air in winter.

Another change made by shoemakers is to place fans and resistance on the soles of shoes. Such fans or resistance are supplied by batteries placed in shoes. Thus, heating or cooling shoe soles is possible by operating such fans and/or resistance, as may be required. However, such shoes may have frequent failures after a while, due to broken resistance and/ or fans. In such a case, such shoes become useless.

Our invention makes a change by heating the shoes from their soles in winter time and by cooling them from their soles in summer time. Thus, it allows us to adjust the heat inside a shoe according to the temperature of the air outside, warm or cool. Our invention makes it possible to prevent many slight sicknesses in feet due to cold or heat. Besides, it ensures that shoes are more preferable by minimizing the weight and bulkiness due to making thick soles or using woll or fiber to protect feet from cold.

Our invention is related with a shoe sole equipped withan electronic circuit and power source nsuring that the peltier modules placed in shoe soles at the stage of molding are heated and/ or cooled bsy low electric power. Moreovcer, such peltier modules can be placed in the necks of boots at the stage of production.

Peltier modules used in our invention require low electric power and are capable of cooling or heating upon applying electric power. Rechargeable batteries and/ or dry accumulators are used in our invention as power source. Such a source of power should preferably be between 1.5 Volts and 24 Volts. The current from the source of power can be automatically turned on and turned off by an electronic circuit at certain intervals in order the provide the required temperature.

Our invention has also a switch to adjust the required temperature. When electric power triggers the peltier modules by an electronic circuit, the desired surface of the peltier module provides the required temperature. A heat plate is used in order to ensure that the heat in the peltier module is smoothly conducted to the required areas of the sole the source of power and the electronic circuit are placed in the heel of a shoe. Peltier modules can also be placed in the neck of a boot during production process. Conductive wires are used between the peltier module, the source of power and the electronic circuit in order to conduct electricity.
