Referring to FIGS. 1 to 3 , the joint protector 1 for preventing injuries in sports activities according to the present invention is characterized by including a body 100 and first and second Velcros 200 and 300 .

Furthermore, Figure 1 shows an embodiment in which the joint protector 1 of the present invention is worn on the wrist, but the joint protector 1 of the present invention is a joint part of the body, for example, the wrist, ankle, elbow, and knee side All of them can be worn to protect the joints of the body, and the width of the body 100 can be adjusted according to the worn part of the joint protector 1.

In the case of the body 100, as shown in FIGS. 2 and 3, it is made of a band shape having a certain width, length, and thickness to protect the wearer's joints. The body 100 is basically made of a material having elasticity and can be stretched or shrunk, and most typically can be made of neoprene.

At this time, tapered portions 101 are formed at both ends of the body 100, and the taper portion 101 is tapered so that its width becomes narrower as it progresses toward both ends, so that the wearer of the joint protector 1 of the present invention It serves to form a cleaner appearance by preventing the end from protruding when wrapped around the joint area of the body.

Furthermore, the first Velcro 200 is formed on the outer surface of the body 100 and the second Velcro 300 is formed on the inner surface of the body 100, so the wearer wraps the body 100 around the joint and , By performing the Velcro coupling between the 2 Velcro (200,300) it is possible to fix the joint protector (1) so as not to be released. At this time, the method of defining the outer and inner surfaces is not limited, but preferably, in the present invention, the surface in contact with the wearer's skin is referred to as the inner surface, and the surface exposed to the outside when worn is collectively referred to as the outer surface. That is, in the wearing state picture of FIG. 1 , only the outer surface is exposed to the outside.

Preferably, in a state where the first Velcro 200 is exposed to the outside from the outer surface of the body 100, the second Velcro 300 formed on the inner surface of the body 100 is aligned with the first Velcro 200. It is possible to fix the joint protector (1) while being fixed in contact with the coupling.

According to such a joint protector (1), it is possible to protect the joint without interfering with the movement of the wearer, so that the injury of the joint can be prevented when performing sports or leisure sports that can strain the joint, Furthermore, it goes without saying that the wearer who needs rehabilitation for a joint can be helpful in rehabilitation.

Figure 4 is a photograph showing the process of wearing the joint protector of the present invention.

More preferably together with the above-described FIGS. 1 to 3, the first Velcro 200 is formed along the longitudinal direction on the outer surface of the body 100, and the second Velcro 300 is formed on the inner surface of the tapered portion 101 Since it may be formed, the joint protector 1 may be fixed by combining the second Velcro 300 formed on the inner surface of the tapered portion 101 with the first Velcro 200. At this time, the second Velcro 300 may be provided on the inner surface of at least one of the tapered parts 101 .

At this time, since the first Velcro 200 is formed along the longitudinal direction on the outer surface of the body 100, the joint protector 1 is formed by adjusting the position where the second Velcro 300 is coupled to the first Velcro 200. Of course, it can be worn by adjusting it to fit the circumference of the wearer's joint.

It goes without saying that a more robust coupling can be achieved by doing so.

5 is a cross-sectional view showing a laminated structure of a body of the present invention.

Referring to FIG. 5, the body 100 of the present invention may be composed of a single structure of an elastic material, but preferably may be composed of a multi-layered structure, such a body 100 includes a base layer 110, A middle layer 120 and a casing layer 130 may be included. At this time, the base layer 110, the middle layer 120, and the casing layer 130 are sequentially stacked in an outer surface direction based on the base layer 110 directly contacting the wearer's skin.

The base layer 110 refers to a surface in direct contact with the wearer's skin, and is characterized in that it is made of a fiber material and can provide a softer touch when in contact with the wearer's skin. Preferably, the base layer 110 may include at least one of polyamide 66, polyester, polyolefin, and cellulose acetate as its material.

The middle layer 120 is laminated on the upper surface of the base layer 110, and is made of a material having elasticity in a thicker state than the base layer 110, and serves to provide elasticity to the joint protector 1. In this case, the middle layer 120 may be made of an elastic material such as neoprene as described above.

The casing layer 130 is laminated on the upper surface of the middle layer 120 and preferably has a thicker thickness than the base layer 110 but a smaller thickness than the middle layer 120, and has a higher elastic modulus than the middle layer 120. It is characterized by being made of a higher elastic material to provide a higher level of elasticity and to increase the strength of the body 100 constituting the joint protector 1. The material of the casing layer 130 is not limited, but may include at least one of silicone resin, polyurethane resin, and polyvinyl chloride resin to exhibit a high level of elasticity.

Therefore, according to the body 100 made of such a triple layered structure, it uses materials with different elasticity to exhibit smooth movement and comfort, but also exhibits excellent joint protection and support based on a high level of elasticity, so that injuries can easily occur. Of course, it is possible to further increase the protection of the site.

At this time, the base layer 110 is in direct contact with the wearer's skin, and when the joint protector 1 of the present invention is repeatedly worn and high-intensity exercise or outdoor activities are performed, the part in contact with the skin, that is, the base layer ( 110) may leak bodily fluids such as sweat, and accordingly, an unpleasant odor, that is, off-odor may occur.

In order to prevent this, the above-described base layer 110 may further include 1 to 10 parts by weight of an off-flavor inhibitor including α-cyclodextrin. In this case, the base layer 110 is made of the above-described polyamide 66 ( 90 to 99 parts by weight of a yarn made of at least one of polyamide 66), polyester, polyolefin, and cellulose acetate, and 1 to 10 parts by weight of an anti-odor agent.

When the base layer 110 is manufactured, the anti-odor agent is directly coated on yarn or the anti-odor agent is included in the base layer 110 by coating the anti-odor agent on the surface after weaving the base layer 110 with the above-described yarn. can be made

At this time, the anti-odor agent contains α-cyclodextrin as an active ingredient, and α-cyclodextrin has a strong deodorizing effect, and thus can remove unpleasant odors that may occur in bodily fluids such as sweat. Preferably, α-cyclodextrin eliminates odor by trapping odor molecules in a circular structure having six sugar ring molecules, thereby effectively removing unpleasant odors that may occur in bodily fluids such as sweat.

Therefore, as the anti-odor agent is included in the base layer 110, it is repeatedly contacted with bodily fluids such as sweat to effectively remove off-odor that may occur in the base layer 110 to which sweat may permeate. When the joint protector 1 of the present invention is repeatedly used for a long period of time, it is possible to prevent an unpleasant odor from occurring.

Furthermore, in order to further maximize the off-flavor removing effect of the off-flavor inhibitor, the off-flavor inhibitor may include α-cyclodextrin and phosphorous ester.

As described above, α-cyclodextrin is a substance capable of effectively removing off-flavor, and phosphite ester is a phosphorous acid-based ester that serves as an antioxidant so that the base layer 110 containing the off-odor prevention agent of the present invention can be applied to the skin. It is added to prevent degradation of quality due to oxidation due to contact with moisture, especially sweat, and to preserve the off-odor removal ability of α-cyclodextrin for a long period of time.

Furthermore, at this time, the composition of α-cyclodextrin and phosphite included in the anti-odor agent is not limited, but preferably α-cyclodextrin and phosphite are added in a weight ratio of 2:1 to 3:1 to remove and oxidize off-flavor. It may be desirable to maintain the ability to prevent and remove off-flavors.

Therefore, according to the configuration of the anti-odor agent, it exhibits the ability to remove off-odor, and at the same time, the base layer 110 containing the off-odor remover is in contact with sweat generated from the skin for a long period of time, so that the active ingredient for removing off-odor is oxidized and the quality of removing off-odor is impaired. can be effectively prevented.

Furthermore, the off-flavor remover may further include an additional composition and may be manufactured through a more characteristic manufacturing process, which will be described with drawings.

Figure 6 is a flow chart showing the steps of preparing the off-flavor prevention agent of the present invention.

Referring to FIG. 6 , the anti-off-odor agent of the present invention may be prepared by preparing a first material (S11), preparing a second material (S12), and completing the anti-off-odor agent (S13). can

(S11) preparing a first material

First, 25 to 45 parts by weight of polylactic acid, 20 to 40 parts by weight of polyhydroxy butylate, and 10 to 30 parts by weight of polyvinylidene fluoride are mixed to produce the first material.

Polylactic acid is a kind of biodegradable plastic extracted from renewable natural raw materials such as starch such as potato and corn, and is characterized by being eco-friendly and harmless to the human body, and has viscosity. Polylactic acid serves as a resin-based base that supports the off-flavor removing component of the above-described off-flavor prevention agent, and at the same time, when the off-odor prevention agent is coated on the surface of the base layer 110, the coated off-odor prevention agent peels off even after prolonged washing or repeated use. Provides a function to prevent loss.

Polyhydroxybutyrate is also a kind of biodegradable plastic, and it is a material that is used as an adhesive for living organisms because of its excellent adhesion. The off-flavor prevention agent is a material that provides adhesive strength so that it can be strongly adhered to the yarn surface of the base layer 110 .

Polyvinylidene fluoride is a thermoplastic fluoropolymer that has excellent chemical resistance and a high melting point of 171°C, and exhibits excellent mechanical properties unlike other fluoropolymers. Excellent chemical resistance and impact resistance. When added as a base material of the off-odor prevention agent, chemical resistance is increased so that the off-odor prevention agent component is not removed even when the joint protector 1 is washed.

Therefore, the manufacturing process of the first material can be said to be a process of manufacturing a resin base that supports the off-odor removing component. At this time, the resin base is made of an eco-friendly and biodegradable material, and at the same time, the mixing property is increased and the adhesive strength is exhibited at an appropriate level. It exhibits high levels of chemical resistance, chemical resistance, and impact resistance so that when the anti-odor agent is coated on the yarn constituting the base layer 110, the coating film can be maintained for a long period of time.

(S12) preparing a second material

Then, 70 to 90 parts by weight of the first material, 10 to 20 parts by weight of α-cyclodextrin, 5 to 10 parts by weight of phosphite, and 1 to 10 parts by weight of lithium magnesium sodium silicate. Mix to prepare the second substance.

α-Cyclodextrin was referred to as a substance having a high level of off-flavor removal ability in the above description, and further helps to stabilize compounds that are easily oxidized, and also serves as an emulsifier to maximize mixability. to be.

As described above, phosphite acts as an antioxidant to prevent the quality of the base layer 110 from being oxidized due to contact with the skin and contact with moisture, especially sweat. and to preserve the off-flavor removal ability of α-cyclodextrin for a long period of time.

Lithium magnesium sodium silicate is added as a bulking agent to increase the strength of the base layer coated with the anti-off-odor agent while helping to maintain the off-odor removing component for a long time by controlling the vaporization rate of α-cyclodextrin.

Therefore, in the process of manufacturing the second material, materials having an off-odor removing ability are mixed with the resin base, and a bulking agent capable of preventing the volatilization of the active ingredient for removing the off-odor is further mixed with the base layer 110 to prevent a decrease in strength. It goes without saying that it can exhibit sufficient durability and strength.

(S13) Step of completing the off-flavor prevention agent

Finally, 85 to 95 parts by weight of the second material, 5 to 10 parts by weight of galactosyldiacylglycerol, and 1 to 10 parts by weight of a phosphite complex are mixed to complete the anti-odor agent.

Galactosyldiacylglycerol is a type of glycerol glycolipid, and, like digalactosyldiacylglycerol, it is known to account for about 70% of the total lipid of thylakoid membranes of prokaryotic photosynthetic organisms lamella or plant chloroplasts. It helps to improve the flexibility of the base layer 110 containing the anti-odor agent and provides a more flexible wearing feeling on the surface of the base layer 110 in contact with the skin, thereby helping to improve the wearing comfort of the joint protector.

The phosphite complex can improve the durability and heat resistance of the base layer 110 when added to the anti-odor agent, and furthermore, the base layer 110 coated with the anti-odor agent is colored by bodily fluids, and phenomena such as material deformation and functional deterioration By performing a role of preventing the , it extends the life of the base layer and provides a function to prevent oxidation of the surface.

Therefore, due to the addition of the anti-odor agent, bodily fluids such as sweat permeate the base layer 110 repeatedly exposed to bodily fluids to prevent the occurrence of off-odor, remove the off-odor, and prevent discoloration due to sweat. Of course, it has the effect of allowing the anti-odor component to last for a long time even during repeated washing.

In addition, at this time, a resin base is prepared step by step, an active ingredient, an off-odor removing component, is added, and then an antioxidant component and a component for improving the flexibility of the coating film are added step by step to improve the off-odor removing function, further preventing oxidation of the composition and physical properties of the film. Of course, it is possible to achieve the effect of providing improvement and flexible tactile sensation step by step.
