The present invention relates to a knee protector that protects the knee from external impact, and to treat and strengthen a damaged knee joint, and more particularly, to a knee injury that occurs during exercise, such as snowboarding, roller brate and other roller skating. In order to prevent this problem, the functional pad is foam-molded with styrene-ethylene-butylene-styrene (SEBS) block copolymer as a main material, and the functional pad is provided with a central guard so as to correspond to the knee at the center, and is extended to both sides. The protector is formed to extend, the center protector relates to a knee protector and a manufacturing method for forming a dome shape convex outward to correspond to the shape of the knee.

The knee protector is a kind of exercise body protector which is worn to prevent the knee from peeling off to protect the knee during various physical injuries that may occur during physical exercise. Knee pads are often worn when exercising on a regular road, such as snowboarding, roller braiding, or roller skating.

Wearing these knee pads is common in athletics and other strenuous sports, especially when using rolling equipment from the ground, such as snowboards and roller braids, which accelerate the movement and thus increase the need for knee protection. .

For example, inline skating enjoyed by many enthusiasts as an example. Since inline skating is a speedy exercise on hard ground, you must wear protective gear and exercise. Like other extreme sports, inline skating requires head protection, and knee and elbow guards are a must-have for inline skating. In particular, in the enthusiasts who enjoy inline skating, the enthusiasts who enjoy thrills with a lot of risk are considerable, and the technology is very diverse. Most of these techniques use the elasticity of the knees a lot, and the posture changes in many ways, especially in movements such as jumps and crossovers, which are quite frequent and fatal.

Because of this, beginners often fall down and have many injuries. Among them, there are many joints due to falls and collisions, and 70% of them are injured in the lower limbs. A period is needed.

In order to solve this problem, various knee protectors have been conventionally presented, and these products are largely divided into two types. First, as shown in Figure 1 is made using a sponge material on the knee portion, second, is a knee protector made using a plastic material as shown in FIG.

In the case of a knee protector using a sponge, the wearing comfort may be good because the sponge is used, but it does not significantly reduce the external impact and has a limitation in that the knee protection function is not properly performed.

Products using plastic materials vary depending on the degree of impact, but there is a risk that the plastic parts are damaged when the impact is very large, causing more injury to the wearer. In particular, the plastic knee guard is relatively flat, while the knee knee is worn, the knee is bent, so that the upper and lower sides of the knee guard and the upper and lower sides of the knee are easy to lift, while the knee guard is moved up and down the knee during movement. It is easy to move, and when the knee is bent, the plastic knee protector has no change in shape, which is very inconvenient.

Accordingly, the present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to provide a knee protector excellent in wearing comfort while protecting the knee from an external impact.

Another object of the present invention is to provide a knee protector that elastically functions to accommodate the change even when the knee changes when worn or during exercise.

Still another object of the present invention is to provide a knee protector which can strengthen the knee joint while protecting the fragile knee.

According to a feature of the present invention for achieving the object as described above, the present invention is used in the knee for physical use to protect the knee from external impact during exercise or in functional use to relieve joint pain or fatigue of the knee during treatment In the knee protector, the pad is composed of a central guard corresponding to the knee, and an extension guard that extends the outer edge of the central guard from side to side includes a soft functional material.

The functional pad is molded using a flexible styrene-ethylene-butylene-styrene (SEBS) block copolymer as a foam.

The center guard has a circular or elliptical shape and has a dome shape with its outer side convex upward.

The center guard is formed such that the thickness of the center is thicker than the thickness of the edge, the thickness at the center of the center guard is at least 6 mm or more, and the thickness of the edge is made 3 mm or more.

The fixing of the primary band and the secondary band may include positioning the outer cover to correspond to one side of both ends of the secondary band and sewing fixing.

According to the knee protector according to the present invention having such a configuration, there is an advantage that a gap does not occur between the knee protector and the knee while effectively absorbing the impact with the outside.

Hereinafter, a preferred embodiment of the knee protector according to the present invention having the configuration as described above will be described in detail with reference to the accompanying drawings.

The knee protector of the present invention is composed of a functional pad 100 and a detachable band 200 for fastening the functional pad 100 to the knee.

The functional pad 100 of the present invention is molded using styrene-ethylene-butylene-styrene (SEBS) block copolymer foams that are flexible in hardness and meet stringent chemical and stability criteria. In addition, if a cushioned and soft material can be molded.

As shown in Figure 3 and 4, the functional pad 100, the central guard 110 corresponding to the knee joint between the thigh and the shin, and the outer edge of the central guard 110 is extended to the left and right It is composed of an extension guard 120.

As shown in FIG. 5, the center guard 110 has a circular or elliptical shape when viewed from the front, and as shown in FIGS. 6 and 7, a dome shape whose outer side is convex upward when viewed from the side. The diameter is determined according to the body shape within the range of 10 cm to 20 cm.

As shown in FIG. 7, the center guard 110 has a predetermined thickness and is formed to have a thickness of at least 3 mm to protect the knee, and the thickness thereof is different from the center and the edge region. That is, while protecting the knee, the thickness becomes smaller gradually from the center to the edge so as not to be uncomfortable when walking or running, the thickness at the center is preferably at least 6 mm or more, the thickness of the edge is preferably made of 3 mm or more.

At the very center of the center guard 110, a ventilation hole 112 of at least 10 mm size is formed to allow ventilation.

Although not shown in the drawing, the inner surface of the central guard 110 may be formed with a number of anti-rolling bumps to prevent slipping or pushing. That is, a plurality of radial or circular irregularities radially outward from the center may be formed at regular intervals.

The unevenness performs a ventilation function to remove moisture by forming a space between the unevenness and the knee in addition to the anti-rolling function. In addition, irregularities are not generated in the knee to perform the function of exhausting sweat.

A plurality of fastening holes 122 through which the fixing band 236 of the detachable band 200 passes are formed in the center guard 110 and the extension guard 120, respectively.

Knee guards are sometimes used for pure physical purposes to protect the knees from external shocks, such as exercise or play, while others may be used on the knees to relieve or treat joint pain or fatigue in the knees. Therefore, in order to satisfy both functions, the embodiment of the present invention further includes various functional materials.

In addition to the foam, the present invention further includes functional materials such as tourmaline and zeolite that emit far infrared rays and anions.

The relative specific gravity (%) of the foam, tourmaline and zeolite is composed of 12 to 18 parts by weight of tourmaline and 1 to 6 parts by weight of zeolite with respect to 100 parts by weight of the foam, more preferably the relative specific gravity of the foam, tourmaline and zeolite. (%) Consists of 16 weight part of tourmaline and 4 weight part of zeolites with respect to 100 weight part of said foams.

If the amount of tourmaline exceeds 20%, tourmaline reacts rapidly with the human body, causing a sensational reaction that causes the skin to become red or itchy. In addition, when the compounding ratio of zeolite is 5% or more, the tourmaline is suddenly stimulated to cause queen bee effect.

Thus, when the tourmaline and zeolite are mixed in the foam, the hardness is lowered and is soft.

The tourmaline is a natural material that is very beneficial to the human body to generate permanent negative ions and far infrared rays without using electricity, by permanently releasing beneficial anions in the body to strengthen the immune system of the autonomic nervous system, to preserve the biocurrent flowing in the body While improving the natural healing power, it releases a large amount of far infrared rays to warm the body to activate the cells and protect the body temperature.

Although it is already well known, when far-infrared rays are shot on body parts that exhibit various pains such as muscle pain, stiffness or numbness, the far-infrared irritates the pain areas, promotes blood circulation, and relaxes the muscles.

In addition, the anion is excellent in reducing power to reduce the acidified skin due to aging, inflammation, or fatigue to weak alkaline, and also serves to reduce harmful substances such as bacteria.

Thus, tourmaline radiating far infrared rays penetrates deep into the body, activates atoms or molecules in the body, and releases various wastes in the body to promote metabolism, thereby contributing to cell regeneration and fatigue recovery.

The zeolite decomposes heavy metals and dead cells, regenerates them into new cells, and functions to increase immunity. In this way, the addition of zeolite with high ion exchange to the tourmaline generates much more negative ions and far infrared rays than when only tourmaline is added. In other words, zeolite has excellent ion exchangeability and catalysis, thus maximizing the effect of tourmaline.

As shown in FIGS. 8 and 13, the detachable band 200 wraps the knee to fix the primary band 210 directly to the functional pad 100 and the primary band 210 to the knee. It is composed of a secondary band 250 that is detachable so that.

As shown in FIG. 8, the primary band 210 includes an inner cover 220 holding the functional pad 100 on the inside and an outer cover 230 holding the functional pad 100 on the outside. .

The band 200 is made of neoprene material. Neoprene is a material for manufacturing gloves, boots, hoods, suits or diving bags, and has excellent elasticity and low deformation.

The outer cover 230 is extended than the functional pad 100, and tears thinly on one side to form a plurality of slits 232. Since the outer cover 230 must have a convex three-dimensional shape in order to correspond to the dome-shaped functional pad 100, the slit 232 is formed such that its width gradually increases toward the outside.

As shown in FIG. 10, the outer cover 230 is fixed to the functional pad 100 using a plurality of fixing bands 236. The fixing band 236 is like an elastic rubber band, and passes through the fastening hole 122 of the functional pad 100 and is fixed to the end of the outer cover 230 by a sewing method or the like. It is a means for fastening the 100 to the outer cover 230.

The inner cover 220 forms a hole (not shown) in the center so that the functional material of the functional pad 100 more effectively acts on the knee, and the size of the inner cover 220 is approximately the outer cover 230. The same, and larger than the functional pad 100.

The secondary band 250 is molded of the neoprene material so that there is no change even if worn for a long time. The thickness is at least 4 mm or more, and the length can be manufactured in various sizes according to the user's body shape.

As shown in FIG. 14, when both ends of the secondary band 250 are provided with velcros 252 and 254 to be freely attached and detached, and male velcro 252 is installed on one inner surface or the outer surface, the other inner surface or the outer surface is provided. The arm Velcro 254 is installed. Both ends of the secondary bands 250 in which the Velcros 252 and 254 are installed are separated vertically. Separating the upper and lower sides is to avoid discomfort on the opposite side of the knee when bending the knee. As shown in FIG. 15, at least one pair of shims 260 are inserted into both ends of the secondary band 250 to alleviate pain when the knee is severely bent.

As shown in FIG. 16, the primary band 210 and the secondary band 250 are fastened by sewing or other methods.
