Description

Midsole capable of generating vibration and electric energy and shoes comprising the same

The present invention relates to a shoe, and in particular, a technology related to a midsole and a shoe including the same in which vibration is generated by a predetermined insert provided in the midsole at the time of walking and electric energy is generated.

Shoes play a role in protecting people's feet in their daily lives, but they require better fit and breathability.

With the development of technology, materials of high quality and high performance are incorporated into the shoe industry, and more various shoes are supplied.

In general, shoes can be classified into several categories according to their use, and can be broadly divided into sneakers, shoes, work shoes, hiking shoes, rock shoes, and other specializations.

Since shoes are basically different in their required characteristics, upper and sole, which are the main elements of shoes, are made of different materials depending on the type of shoes.

Meanwhile, in Korea, diabetic patients are rapidly increasing due to changes in eating habits, and since diabetes may cause complications and may be life threatening, active prevention and management are required.

Diabetics are very sensitive to even minor injuries, because bacterial infection through the wound can cause serious illness.

If diabetics do not control their blood sugar for a long time, complications in blood vessels and nerves can easily cause lesions on the feet. The disease causes dullness of the feet, making it easy to hurt, as well as sweating, rough skin, and severe cracking. When an ulcer occurs, blood circulation is not sufficient to heal due to vascular disorders, and bacteria easily penetrate the wound due to a decrease in resistance to bacteria. Because of these factors, once a complication occurs, it does not heal easily and lasts longer.

Foot care is very important in diabetics because there are calluses, corns, athlete's foot, athlete's foot sores, ulcers and ulcers, and in the worst case there is a serious need to cut the foot.

Therefore, diabetic patients need to be careful when choosing shoes. Firstly, it is better to wear comfortable shoes with low heel and wide front. Second, soft leather and avoid synthetic resin products. It is said that it is good to absorb shocks because of the thick floor, and to wear light shoes, and to avoid wearing high heels, boots and slippers.

As a related art of the present invention, Korean Patent Publication No. 10-2006-0001956, "Walking-only diaphragm equipped with a leaf spring airbag," is known, and FIG. 1 is a cross-sectional view of the diabetic according to the prior art.

As shown in the figure, two leaf spring top plate hangers 8 'are formed on the left and right sides of the spring steel leaf spring 8, which is connected in a diamond shape, and two plates on the left and right sides of the same leaf spring. A spring bottom plate hanger (8 ") is formed, and the springs (8) having a single cushion are assembled by facing each other so that both ends coincide with each other so that the outsole (2 ') of the outsole (2') of the outsole of the shoe sole (2) It is a walking-type diabetic with a fitted leaf spring cushion air bag.

The prior art is to cushion the inside of the sole good spring springs to ease the shock when walking, and to improve the breathability to help the diabetic patients.

In recent years, since the shoe itself is considered as a fashion item, external design is also important in addition to functions, and according to this trend, shoes that emit light with LEDs attached to the midsole or upper of the shoe are also released.

And the demand for heat insoles to keep your feet warm in winter is also increasing.

In other words, shoes should be able to give a more comfortable fit than simply worn on the foot, in the case of specialization is required functionality to help the user's health, decorative shaving as a fashion item is important.

Therefore, in the present invention, the vibration is generated in the insert embedded in the midsole by the movement of the foot during walking to stimulate the sole of the foot, and at the same time to produce electricity to be used as a power for heating insoles or LEDs To provide a midsole and shoes that can generate vibration and electrical energy.
