Next, the strap 120 grips the grip portion 220 of the handle portion 200 in a state in which the strap 120 is coupled to the hanging neck 110 around the calf to hold the center.

In this process, the control unit 210 of the handle unit 200 is adjusted to fit the user's height.

In this state, it is possible to move the crutches through a sliding motion by pushing the user's uncomfortable leg and rotating the wheel unit 400 .

The structure of the present invention described above eliminates the shock and discomfort generated in the armpit because the user can simply hold the crutches by hand instead of the conventional method of crutches that were inserted into the user's armpit.

In addition, there is an effect of relieving the inconvenience of both hands by providing a single crutch rather than a pair of crutches provided to hold the center of the existing crutches.

In addition, due to the ability to adjust the length of the handle part 200 and the support part 300, portability is increased and there is an effect that can be easily stored in a narrow space.

In addition, since it can be used by simply pushing with the feet through the wheel unit 400, it is possible to eliminate the inconvenience of behavior and to move freely and quickly, thereby providing an effect of quickly escaping obstacles and dangerous situations.

In addition, there is an effect of relieving pain in the wrist and palm that occurs during running through sliding motion by the wheel unit 400 rather than movement through running up of existing crutches.

Due to the feature that the body is in constant contact with the holder 100 of the present invention, sweat may occur, and a humid environment may be formed due to sweat, which may generate off-odor and odor, and may adversely affect the skin.

To prevent this, it is preferable that a coating layer for antibacterial and deodorizing is formed on the holding part 100 of the present invention.

The coating layer includes fine powder shungite, fine powder illite, fine powder zeolite, fine powder elvan, fine powder bentonite, fine powder diatomaceous earth, fine powder germanium, fine powder ocher, fine powder alumite, fine powder jade and these An antibacterial and deodorizing composition comprising an inorganic powder selected from the group consisting of a mixture of is applied.

The antibacterial and deodorizing composition of the present invention is capable of adsorbing a specific component physically or chemically, including the inorganic powder, and can achieve an antibacterial effect by adsorbing odors and other harmful bacteria.

The fine powder referred to in the present invention refers to a product that is crushed by a ball mill, jet mill, or other grinding device or manufactured to have the properties of a fine powder in a synthesis process, and the fine powder is defined as having an average particle diameter of 100 μm or less.

Geite as used in the present invention is produced as a layer (up to 2m in thickness) or a lens shape in shales with low metamorphism rich in small graphite microcrystals of the Jatulian period of the Proterozoic Era in Shunga near the northern part of Ladoga Lake in Karelia, Russia. . It is pitch black, dense, opaque, metallic luster. soft Hardness 2.5. d 1.75~1.80, graphitic acid is made from concentrated nitric acid without melting in a fire stand.

Illite as used in the present invention has a chemical composition of (K, H ₃ O) Al ₂ (Si, Al) ₄ O ₁₀ (H ₂ O, OH) ₂ . In terms of chemical composition, some are close to muscovite, but relatively SiO ₂ , MgO, H ₂ O are high, and K ₂ O is small. It is a mineral in the same family as hundreds of mica. Hardness 1 to 2, specific gravity 2.6 to 2.9. Cleavage is complete, the streak color is white, and there is earthy luster. There is a view that it is not an independent mineral in terms of chemical composition or crystal structure, but a mixed mineral containing other elements. It is produced in aluminum-rich heterogeneous or tuff sedimentary rocks, and is produced as an altered mineral of hydrothermal mineral bedrock.

The zeolite referred to in the present invention is also referred to as zeolite. There are many types, but they have a lot of water content, crystal properties, acidity, etc. in common. The hardness does not exceed 6, and the specific gravity is about 2.2. It is usually colorless transparent or white translucent. It got its name because it boils and expands when heated with a blowpipe. Most types dissolve in hydrochloric acid and often form glue, but a few types do not dissolve in hydrochloric acid. The main types include chalcedony stone, fisheye stone, chabazite, soda zeolite, heurandite, stilbite, lomontite, and inesite. It is produced in voids or fissures of basic igneous rocks such as basalt and pyroxene tuff, and sometimes exists as a secondary mineral in granite and gneiss. In addition, there are cases where it is produced in gold veins and other veins. In terms of crystal structure, the bond between each atom is loose, so even if the moisture filling the gap is released at high heat, the skeleton remains intact, so it can adsorb other particulate matter. Using this property, it is used as an adsorbent and as a molecular sieve that separates fine particles of different sizes.

The elvan stone referred to in the present invention is known as a term used in Chinese oriental medicine and belongs to the granite class to be classified geologically. Like quartz porphyry, feldspar porphyry, and granite porphyry, the rock name corresponds to quartz-monzonite. Quartz and feldspar are closely mixed. The yellowish-white, light yellowish-brown, light gray, dark green, or light green rocks with evenly mixed red or white dots look like rice balls made of barley rice, so the name elvan was given. The main components are silicic anhydride and aluminum oxide, and a small amount of iron oxide is contained. Known as a medicinal stone is a yellowish-white elvan stone. In the past, it was used as a filtering agent to purify pills and as an anti-inflammatory agent to treat skin diseases such as boils or boils on the back. According to Donguibogam, its properties are sweet, warm, and non-toxic. It consists of 30,000 to 150,000 pores per 1 cm ³ and has strong adsorption properties, and contains about 25,000 kinds of inorganic salts. Because it acts to exchange ions with heavy metals, it is also used as a harmful metal remover, and it is known that far-infrared rays are emitted when heat is applied to this rock. Because of these characteristics, it is used in various industries such as saunas, tableware, and medical devices.

Benzonite referred to in the present invention often contains quartz, feldspar, zeolite and the like. The color represents white, gray, light brown, light green, etc. It is produced as a dense mass with a pearly luster and waxy luster and has a sense of fat. Tuff and glassy rhyolite have been altered. Its uses are very wide, and it is also used as a main component of oil drilling water, a casting-type binder, a mixing agent for ceramic raw materials, and a base agent for ointment. The name is derived from the strata of Wyoming, USA, where it was discovered.

Diatomaceous earth referred to in the present invention is mainly composed of silicic acid (SiO2) and has a white or off-white color. It is light and soft enough to smear powder when touched with a finger. Because it is a fine porous material, it has strong absorbency and is a poor conductor of heat. Diatomaceous earth in Korea is produced as earth in the tertiary or quaternary strata. In the tertiary period of the ancient period in Korea, fault movements in the northeast or northnortheast direction occurred, resulting in the formation of earth basin sedimentary basins in several places. The Yeongil Basin, the Gilju-Myeongcheon Rift Zone, the Seoul-Wonsan Rift Zone, and the Tuman River Basin were formed, and the tertiary layer was deposited here. When the sedimentary layer was formed, diatoms were deposited in small shallow lakes or freshwater basins in various places to form mineral deposits. Among these sedimentary basins, diatomaceous earth in Yeongilman Bay is the largest in terms of diatomaceous earth deposits, and is found intensively in Wolseong and Yeongil, Gyeongsangbuk-do. Other North Korean regions include Haenghyeon-ri, Munsan-myeon, Anbyeon-gun, Hamgyeongnam-do, Namsan-ri, Anbyeon-myeon, Anbyeon-myeon, Bupyeong-dong, Junam-myeon, Gyeongseong-gun, North Hamgyeong-gun, Hoemun Mine in Jubuk-myeon, Gyeongseong-gun, Sanbon Mine in Ungpyeong-myeon, Gilju-gun, Myeongcheon Mine in Myeongcheon-gun, Baekrok Mine in Seomyeon, Myeongcheon-gun, Gangwon-do. Pyeonggang-gun, Gosap-myeon, Sepho-ri and other producing areas are known. The development of diatomaceous earth as a mineral deposit in Korea began in 1941 when it was incorporated as a designated legal mineral according to the 'Joseon Mining Ordinance'. Since then, domestic diatomaceous earth deposits have been discovered in various places, and in particular, diatomaceous earth produced in Iil-ri, Yangbuk-myeon, Wolseong-gun, Gyeongsangbuk-do was used as a raw material in Nodong-ri, Gyeongju-si to manufacture Asahi stoves in Japan. In recent years, it is used for fireproof materials, and because of its strong absorbency, it is mostly used as a filter medium for purification of industrial water, water supply, medicines, and food. In addition, it is also used as a filler for plastic and paper, an adsorbent for dynamite, a hemostatic agent, and a mixture of cement.

Germanium referred to in the present invention has an element symbol of Ge, an atomic number of 32, and an atomic weight of 72.59±3. Its existence was predicted by D. I. Mendeleev in 1871 and called eka silicon, but in 1886, German chemist C. A. Winkler discovered sulfur in silver germanium stone (Ag GeS) and named it after the German Latin name “Germania”. Since it is similar to silicon, it is widely present by replacing silicate silicon in the earth's crust, and is contained in sulfide minerals or coal containing copper or zinc, but minerals mainly composed of germanium are extremely few.

The alum stone referred to in the present invention is also called alum stone. The chemical composition is KAl ₃ (SO ₄ ) ₂ (OH) ₆ . It appears as hexagonal plate-shaped or impression crystals, but it is usually bulky or granular. It has a hardness of 3.5 to 4 and a specific gravity of 2.6 to 2.9. The crystalline type has complete cleavage on the bottom, and the cleavage surface has a pearly luster. The odd one has no luster. It is white, gray, and sometimes red, yellow, or reddish-brown. The streak color is white. It is insoluble in hydrochloric acid, but soluble in potassium hydroxide or hot sulfuric acid. It is produced from volcanic rocks that have undergone hydrothermal alteration.

The jade referred to in the present invention refers to a substance that is dense and hard, transparent and beautifully shiny, and polished to give a luster. Mineralogically, nephrite is a kind of amphibole, and jadeite is a kind of alkali pyroxene. Nephrite is often milky white, and there are also green, yellow, and red, and jadeite is green and white. There are various names depending on the color, but white jade and jade are representative. It has been valued in the Orient since ancient times, and has been used as a decorative stone and jade vessel. Nephrite is produced as veins in crystal schist or gneiss in places such as Turkey, and in the contact zone of granite in northeast China. Jadeite is produced by forming veins among serpentines in Myanmar, and also produced in Yunnan, China and the Tibetan Plateau. Although jade in a narrow sense refers to jade, the present invention is not limited thereto, and jade referred to in the present invention is defined to include all of the above-mentioned jade in a broad sense.
