BACKGROUND OF THE INVENTION
The present invention relates to a knee joint supporter used for painful knee joint diseases.
[0002]
[Prior art]
As a supporter for pain around the patella typified by patella ligamentitis and Osgood Schratter disease, many supporters using a pad for compressing the patella tendon have been put into practical use. It has the effect of diminishing the load, and has a certain reputation. However, the conventional one uses the compression force of the main body material when taking the method of preventing the high position of the patella in order to reduce the load on the patella tendon, and it is necessary to increase the pressure in the thigh circumference direction For this reason, there is a possibility that the motor performance may be hindered, and it is not always effective. Further, conventional pads used around the knee are limited in function to the stable function of the patella, and are not optimized to prevent the high level of the patella. In addition, many band-shaped ones are used for the purpose of removing knee pain, but the purpose is to reduce stress concentration on the pain site by compressing the patella tendon, and the upper end of the patella is compressed in the thigh circumference direction. By doing so, it is used for the purpose of alleviating pain by attenuating the upward displacement of the patella and reducing the stress concentration on the affected area.
[0003]
[Problems to be solved by the invention]
The object of the present invention is to prevent local stress concentration on the tendon by effectively compressing the patella tendon against pain around the patella represented by patella ligamentitis and Osgood Schratter disease. Decrease by pressing the upper part of the patella, which is thought to increase pain, from the top, and further reduce circumferential pressure on the thigh muscles such as the quadriceps and hamstrings that hinder movement It is to provide a knee joint supporter capable of doing this.
[0004]
[Means for Solving the Problems]
In order to solve the above-described problems, according to the present invention, a main body that surrounds the knee joint and compresses the knee joint, and a reverse attached to the main body so as to surround the patella from both sides below the knee joint. A U-shaped pad, a hook-and-loop fastener attached on the inverted U-shaped pad, and a crus that can be engaged with the hook-and-loop fastener on the inverted U-shaped pad by passing through the patella tendon region in the mounted state A belt.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, the main body is formed in a cylindrical shape by a stretchable material so as to surround the knee joint, and an inverted U-shaped pad is attached on the main body so as to surround the periphery of the patella, and both ends of the inverted U-shaped pad are attached. A lower leg belt with a hook-and-loop fastener on the bottom and a hook-and-loop fastener on the back is connected to the main body at the back of the lower end of the main body, crossed at the patella tendon, and both ends engage with the hook-and-loop fastener on the inverted U-shaped pad It is advantageous to do so.
[0006]
【Example】
Next, the present invention will be described with reference to embodiments shown in the drawings.
[0007]
1, a, b, and c are a front view, a left side view, a right side view, and d and e are a front view and a rear view, respectively, of a fastening belt according to an embodiment of the present invention. It is. 1 is a main body, which is formed in a cylindrical shape that wraps around the knee joint from an elastic material, and the part facing the popliteal part when worn is cut and sewn for the purpose of preventing sagging of the main body fabric when bent Thus, an opening 2 is formed. A pad 3 formed in a U shape from an elastic material so as to surround the opening 2 is fixed on the main body 1 by a pad cover 4 so that the U shape faces downward. The hook-and-loop fasteners 5 and 6 are attached to the lower portions of both inverted U-shaped legs of the pad cover 4, and the hook-and-loop fasteners 5 and 6 extend from the level of the opening 2 to the vicinity of the lower end of the main body 1. A patella tendon pad 7 is attached to the main body 1 below the opening 2. The patella tendon pad 7 can be attached to the inside or the outside of the main body 1 using the same kind of material as that of the main body.
[0008]
Reference numeral 8 denotes a crus belt made of a stretchable or non-stretchable material like the main body, and both end portions 9 and 10 are formed to be slightly upward from the central portion 11. On the back side, hook-and-loop fasteners 12 and 13 are fixed to both sides of the central portion 11, and hook-and-loop fasteners 14 and 15 are fixed to both ends. The lower leg belt 8 is used by being wound around the lower leg part of the main body 1 in the wearing state. Therefore, the central part 11 located on the back side of the knee is formed to be slightly wider and prevent local compression.
[0009]
The material of the main body 1 is a mixture of fibers such as acrylic, nylon, polyester, polypropylene, hair, and elastic polyurethane, rubber, etc., elastomer sheet, such as chloroprene rubber, urethane, EVA (ethylene-vinyl acetate) -Copolymers), PVC (polyvinyl chloride) sheets, jerseys laminated, the above-mentioned sheets formed alone, or different types of sheets laminated in multiple layers, etc. Material can be used. Inverted U-shaped pad 3 is made of rubber, EVA (ethylene-vinyl acetate-copolymer), silicon, PVC (polyvinyl chloride), PP (polypropylene), PE (polyethylene), urethane, etc. Can be used. The material for the lower leg belt is the same as the material of the main body when using a stretchable one, and when it is non-stretchable, a woven or non-woven fabric of acrylic, nylon, polyester, polypropylene, hair, etc., or its A woven or non-woven fabric provided with a resin can be used.
[0010]
Next, the mounting method of the supporter of this invention is demonstrated using FIG. a is a front view of a mounted state, b is a right side view of the mounted state, and c is an operation explanatory diagram. As shown in the figure, the lower leg is first inserted into the main body 1, the main body 1 wraps around the knee joint, the U-shaped leg joint portion of the inverted U-shaped pad 3 is above the patella 21, and the opening 2 is above the patella 21. Then, the patella tendon pad 7 is lifted to such a position as to be on the patella tendon region. Next, the crus belt 8 is attached so that the center part 11 is located at the rear lower end of the main body 1, and hooked onto the hook-and-loop fasteners 5 and 6 of the main body 1 with hook-and-loop fasteners 12 and 13. Turn forward, cross over the patella tendon region, that is, over the patella tendon pad 7, and engage the hook-and-loop fasteners 14 and 15 at both ends with the hook-and-loop fasteners 5 and 6 of the main body 1, respectively. The inverted U-shaped pad 3 suppresses the displacement of the patella to the higher position, that is, the upper part of the patella tendon is applied to the patella tendon by the crus belt 8, and the inverted U-shaped pad 3 is displaced upward particularly when the foot is bent. This effectively prevents the presence of FIG. 3c illustrates the action state of the force when the foot is bent. The main body 1 wraps around the knee joint, an appropriate compression force is applied to the knee joint by the modulus of the main body 1 made of an elastic material, and the crus belt 8 applies a compression force on the patella tendon portion in the lower leg portion of the main body 1 and vice versa. When a force is applied to the U-shaped pad 3 and a downward force is applied to the inverted U-shaped pad 3 as indicated by an arrow when the knee joint is bent, the inverted U-shaped pad 3 is directed downward with respect to the patella 21. It works to suppress the patella and prevents the high position of the patella. Further, since the thigh portion is only the main body 1 and there is no particular fastening belt, there is little compression in the circumferential direction.
[0011]
In the above-described embodiment, the hook-and-loop fasteners 5 and 6 of the main body 1 are attached to the lower portions of both sides of the inverted U-shape of the pad cover 4. However, the present invention is not necessarily limited to this position. It is only necessary that the crus belt 8 can be attached to a position where the crus belt 8 acts on the inverted U-shaped pad 3 so as to suppress the upward displacement when engaged with the upper U-shaped pad 3.
[0012]
In the above-described embodiment, the crus belt 8 is engaged with the patella tendon so as to intersect with each other. However, the crus belt 8 does not necessarily need to be intersected. Any position where the suppressing force can be applied is acceptable. For example, it is wound around the lower leg passing over the patella tendon and engaged with the hook-and-loop fasteners 5 and 6 of the inverted U-shaped pad cover 4 to May be engaged.
[0013]
The patella tendon pad 7 is not necessarily provided, but by providing it, an effective compression force can be applied to the patella tendon region.
[0014]
The main body 1 is also formed in a cylindrical shape in the above-described embodiments, but it is formed in a substantially rectangular shape, wound around the knee joint, and the both ends thereof are engaged with each other with a hook-and-loop fastener or the like. Then, it may be an open type that is cylindrical.
[0015]
Table 1 shows the difference of various actions in comparison with the conventional supporter of the present invention. In other words, conventional supporters include the normal supporter type, the padded supporter type, the thigh wrapping band type, and the crus wrapping band type, the thigh circumferential direction compression action, the patella tendon compression action, and the patella bone stabilization action. In addition, the effect of preventing the high level of the patella, the pressure effect in the circumferential direction of the crus, and the pressure effect in the circumferential direction of the crus muscle group are shown on the basis of strong, medium and weak. As is apparent from this table, it can be seen that the supporter of the present invention has good characteristics in all items as compared with the conventional supporter. That is, although the compression action on the patella tendon, the patella stabilization action, and the high patella prevention action are high, the compression action in the thigh circumference direction and the compression action in the crus muscle group circumference direction are small.

【The invention's effect】
According to the present invention, since the inverted U-shaped pad arranged around the patella is fixed by the belt attached to the lower leg portion of the main body, excessive upward displacement of the patella is prevented by the function of the inverted U-shaped pad. In addition, stress concentration on the patella tendon is attenuated, and the therapeutic and preventive effects on the disease can be maintained. On the other hand, since there is no compression in the circumferential direction of the thigh, exercise performance can be kept good. In addition, since the inverted U-shaped pad extends to the side of the main body, it can also have the effect of the side stay provided in the supporter, while suppressing the side swaying, Sag can be reduced.
