Description

The present invention relates to a protective device. In particular, the present invention relates to a protective device capable of protecting the knee during quadrupedal walking exercise.

While the average life expectancy of people is increasing, the difference between the average life expectancy and the healthy life expectancy (in Japan, the average life expectancy is about 10 years longer than the healthy life expectancy) makes it impossible for the elderly to lead an independent life. The period is also getting longer. If the difference between average life expectancy and healthy life expectancy is large, not only will the elderly not be able to lead a satisfying life for a long period of time, but it may also put a mental, physical and even financial burden on the people around them. .. Therefore, by taking measures against locomotive syndrome (motor dysfunction) and prolonging the healthy life span, it is possible to prevent the elderly from becoming bedridden or otherwise in need of long-term care. It is preferable that the care recipient can do as many personal things as possible.

At rehabilitation facilities and long-term care facilities, rehabilitation is carried out for the elderly and those requiring long-term care. However, rehabilitation at such facilities may be carried out in a limited manner, such as several times a week under the guidance of a specialist. Conversely, it can be considered that most of the week is not exercising. Although it is necessary to exercise on a daily basis in order to extend healthy life expectancy, the elderly and care recipients are forced to settle for limited exercise due to various restrictions at present. Then, since they do not exercise on a daily basis, the bone mass and muscle strength of the elderly and care recipients decrease, and as a result, the energy to exercise is diminished and they stop exercising, resulting in a further decrease in bone mass and muscle strength, which is a negative spiral. Occurs.

However, if exercise can be routinely performed without relying on special rehabilitation, that is, if it can be carried out diligently every day, the above negative spiral can be converted into a positive spiral. Specifically, if it is an exercise that is natural for the human body, is the safest for most people to perform, and does not require specialized knowledge, even elderly people and care recipients can do it alone. You can exercise on a daily basis and expect to extend your healthy life expectancy. As such an exercise, considering that the origin of human skeletal / muscle formation is quadrupedal walking, a quadrupedal walking exercise (so-called high-high) in which both hands and legs (below the knee) are attached to the ground is used for walking. Exercise) is expected to be an exercise that can extend the healthy life span and is easy to become a habit. That is, the quadrupedal walking exercise is an exercise in which the limbs under its own weight are interlocked, and there are a wide variety of exercises. Therefore, men and women of all ages can exercise. As a result, if it is a four-legged walking exercise, the exercise can be easily habituated both physically and mentally, and improvement in health can be expected. However, when an adult walks on four legs, if the ground or floor that comes into contact with the limbs does not have the flexibility to absorb the impact of the exercise, the impact of the exercise is applied to the palm or knee, and the palm or knee is affected. It may hurt. And, unless the place considers the quadruped walking exercise, most of the places are not suitable for the quadruped walking exercise, and the quadruped walking exercise in such a place is unrealistic. Therefore, it is required to protect the part in contact with the ground, make the four-legged walking exercise realistic, and enable it to be carried out safely and comfortably anywhere.

Conventionally, a knee supporter that is detachably attached to a desired position of the knee to prevent the knee from becoming dirty and protect the knee, and has an elastic member having a substantially square pillar shape and a mounting member having a substantially band shape. A knee supporter is known which has an elastic member that presses the knee when the knee is buckled to hold the knee, and the attachment member is wrapped around the lower part of the knee to arrange the elastic member in a desired position. (See, for example, Patent Document 1). According to the knee supporter described in Patent Document 1, it is possible to prevent the knee from becoming dirty and to protect the knee while the knee is attached. In addition, two pairs of elastic strings with hook-and-loop fasteners are provided on the edge of the cushioned seat body, and the pair of strings are placed on the knee joint with the cushioned seat body covered on the knee. Cushion by turning to the back of the leg to engage the front hook-and-loop fasteners, and turning the other pair of strings to the back of the leg under the knee joint to engage the front hook-and-loop fasteners. A knee pad configured to be worn on the knee is known (see, for example, Patent Document 2). According to the knee pad described in Patent Document 2, when the knee is put on the ground or the floor in order to work in a low posture in the work of a flower bed or a do-it-yourself work, the knee may hurt or the pants may become dirty. Can be prevented.

Utility Model Registration No. 322147 Japanese Unexamined Patent Publication No. 10-046411

However, in the knee supporter described in Patent Document 1, since the mounting member is only wound around the lower part of the knee, when the knee supporter is brought into contact with the floor and the knee is moved back and forth and left and right, the elastic member is released. It easily slips off the knee. Further, in the knee pad described in Patent Document 2, although the knee pad is attached to the knee with a pair of strings, when the knee pad is brought into contact with the floor and the knee is moved back and forth, the operation is performed several times. Not only does the knee pad shift from the knee, but when the knee is moved to the left or right, the knee pad rotates around the leg and shifts from the knee. Furthermore, in the first place, conventional protective equipment such as knee supporters and knee pads such as Patent Document 1 and Patent Document 2 do not assume that the knee is protected during quadruped walking exercise (quadruped walking exercise). Since it is not assumed that a load corresponding to the weight of a person is applied to the knee and the protective equipment, the knee cannot be properly protected during the quadrupedal walking exercise (that is, when the quadrupedal walking exercise is continued).

Therefore, an object of the present invention is to provide a protective device that does not cause damage such as pain to the knee during a four-legged walking exercise that is performed by bringing the knee into contact with the floor or the like, and does not slip (take off) from the knee. be.

[Embodiment]
<Outline of protective equipment 1>
FIG. 1 shows an example of an outline of a usage state of a protective device according to an embodiment of the present invention.

The protective device 1 according to the present embodiment is worn on the knee when the person 5 walks on four legs to reduce or prevent damage such as pain to the knee. Specifically, as shown in FIG. 1, a protective device 1 is attached to each of both knees 6. In addition, hand protective equipment 2 is attached to both hands 7. When quadrupedal walking exercise is performed without wearing protective equipment on both hands and knees, not only pressure is applied to the palms and knees and pain is felt, but also the ground and floor come into contact with the palms and knees, causing the palms and knees to come into contact with each other. May injure the knee. Therefore, from the viewpoint of daily quadrupedal walking exercise, it is required to use protective equipment that protects the palm and knees.

In particular, in the quadrupedal walking exercise, there is not only an exercise that advances back and forth, but also an exercise that walks on four legs in a circle or a figure of eight (that is, an exercise that bends and advances). When performing a bending motion, a force is applied to the protective device 1 not only in the front-rear direction but also in the left-right direction. Further, in this case, a force in the direction in which the protective device 1 rotates about the leg is also applied to the protective device 1. Therefore, it is required that the protective device 1 does not deviate from the knee 6 due to the front-back, left-right (and up-down) forces applied to the protective device 1. As will be described later, the protective device 1 according to the present embodiment has a structure in which a force is applied to the knee 6 in a direction opposite to the force applied to the knee 6 by contacting the knee 6 from a plurality of directions, and the force is applied to the force. It has a structure that applies a force in the direction to follow (for example, a force in the direction to follow the front acts on a force in the forward direction, and a force in the direction to follow the rear to the force in the rear direction). It has a structure in which a force acts. Further, it has a structure in which a leftward force acts on a rightward force and a rightward force acts on a leftward force). That is, when the protective device 1 is attached to the knee, the protective device 1 is provided with a point, line, and / or surface contact area in the area where a force that deviates from the position of the knee is applied, so that the protective device 1 can be displaced or removed from the knee. Can compete. As a result, the protective device 1 according to the present embodiment does not deviate or come off from the knee due to the quadruped walking exercise, and the wearer can perform the quadruped walking exercise with peace of mind. The same applies to the hand protective device 2.

By using the protective device 1 and / or the hand protective device 2 according to the present embodiment, the wearer can perform the quadrupedal walking exercise without feeling pain in the palm and knees. The protective device 1 and / or the hand protective device 2 does not shift from the knee or palm even when a force is applied in the front-rear direction or the left-right direction by contacting the floor, so that the wearer can exercise with peace of mind on four legs. Can be executed.

Since the four-legged walking exercise can be carried out if there is a place of about 2 tatami mats, the wearer can carry out the exercise by himself / herself at any time and place. The four-legged walking exercise warms the whole body immediately and loosens and strengthens the muscles of the whole body (especially the muscles around the shoulder blades and hip joints). However, it can also be applied to prevent injuries of various athletes. That is, since the quadruped walking exercise can safely train each part of the human body, it is effective for all people and people with a wide range of physical conditions, and is used for rehabilitation, daily exercise, training of athletes, etc. be able to. Further, the quadruped walking exercise is expected to be effective for low back pain, stiff shoulders, and / or diet, etc. Therefore, by using the protective device 1 and / or the hand protective device 2 according to the present embodiment, the quadrupedal walking exercise is used. Walking exercise can be easily routineized.

In the quadrupedal walking exercise, the muscles directly attached to the spine (erector spinae muscles, latissimus dorsi muscles, and iliopsoas muscles) are used at the same time, and the rate at which the upper and lower body move in tandem (interlocking rate). (Especially, the interlocking rate between the latissimus dorsi (upper body) and the gluteus maximus (lower body), which are not sufficiently interlocked when walking on two legs, is very high). Therefore, the fascia line is strengthened by the quadrupedal walking exercise, which not only strengthens the muscle strength of the whole body, but also has the effect of expanding the range of motion of the joints and correcting the distortion of the whole body, and also the blood vessels and lymph vessels of the whole body. It can be expected to have the effect of stimulating every corner of the nerves and meridians. Furthermore, the spinal reflex of the wearer is also strengthened by training the interlocking of the upper and lower body, and the wearer can respond flexibly and quickly to environmental changes (for example, to respond to a fall due to a passive stumbling). Will be. And in Japan, the number of deaths due to "falls" has reached about 10,000. Here, even if a person does not die due to a "fall", the elderly may become a person requiring long-term care such as being bedridden due to a fracture or hospitalization based on the fracture, and "fall" is a major issue in an aging society. be. On the other hand, the quadruped walking exercise is an effective exercise as a fall prevention measure, and is considered to be very useful in the future. The exercises for moving the limbs include swimming, dancing, and bouldering, but these exercises have a lower interlocking rate between the upper body and the lower body than the quadruped walking exercise. From this point as well, it can be said that the quadrupedal walking exercise is useful.

For example, one end of the band portion 16 is connected to a first partial band cord 130 located on the side surface of the protective device 1. In this case, the one end is connected to the first partial band cord 130 by the rotating portion 17 so as to be rotatable with respect to the first band cord 13. Further, the other end of the band portion 16 is connected to the second partial band string 132 located on the side surface of the protective device 1. In this case, the other end is connected to the second partial band cord 132 by the rotating portion 17 so as to be rotatable with respect to the first band cord 13. Here, the position of the rotating portion 17 in the height direction (the position when the bottom surface 100 is the reference plane and the direction toward the main surface 102 is the height direction in the side view of the protective tool 1) is from the outsole portion 10. It is preferable that they are separated by a predetermined distance. As a result, the band portion 16 is provided from one sidewall portion 12 toward the other sidewall portion 12, and at least a part thereof is provided so as to intersect the first band string 13 (that is, the band portion 16 is provided. The end portion overlaps with the first band string 13, and the band portion 16 and the first band string 13 intersect at this overlapping portion. The end portion of the band portion 16 starts from the first band string 13. It may protrude to the side of the second band string 14).

The band portion 16 can be made of the same material as the outsole portion 10.

The band portion 16 has the other edge along the surface of the leg on the knee side of the wearer (the surface of the thigh on the knee) from a predetermined position of the first band string 13 on the one edge side of the outsole portion 10. By being connected to a predetermined position of the first band string 13 on the side of the portion and displaceably connected to the first band string 13, the protective device 1 is attached to the leg when the leg moves upward or upward and forward. At the same time, it causes the action of following up and forward (that is, the action of keeping the knee and the protective device from separating). That is, the band portion 16 is caught on the wearer's knee and prevents the protective device 1 from coming off. Further, since the band portion 16 can be displaced with respect to the first band string 13, the angle of the band portion 16 with respect to the outsole portion 10 can be changed independently. As a result, the protective device 1 can be worn more tightly (strongly) by fitting the size of the wearer's knee.

Hereinafter, the details of the functions of each component of the protective device 1 on the wearer's knees and around the knees will be described.

<Explanation that the protective device 1 presses the wearer's knee from multiple areas>
FIG. 4 shows an outline of the effect of a predetermined area of the protective device according to the present embodiment on the wearer's knees and legs.

First, the following three functions are required for the protective device 1 used for the quadruped walking exercise.
(1) Prevent the protective device 1 from coming off the knee when the wearer moves forward (that is, prevent the protective device 1 from slipping off the knee and coming off behind).
(2) Prevent the protective device 1 from coming out of the knee in the forward direction when the wearer moves backward.
(3) When a lateral (horizontal) force is applied to the protective device 1, the protective device 1 is prevented from rotating around the wearer's leg so that the protective device 1 does not come off sideways (slide). To withstand the force of force) and to withstand the force of the horizontal direction.

In the protective device 1, the band portion 16 mainly exerts the function for the above (1), the pad portion 15 mainly exerts the function for the above (2), and the sidewall portion 12 mainly exerts the function for the above (3). That is, when the wearer wears the protective device 1 on the knee, a plurality of regions formed by each component of the protective device 1 come into contact with the legs centered around the wearer's knees, so that the wearer 4 Even if the protective device 1 moves back and forth or laterally by walking with legs, it prevents the protective device 1 from slipping off or coming off from the knee and rotating around the knee.

Specifically, as shown in FIG. 4, when the protective device 1 is attached to the wearer's knee, the band portion 16 comes into contact with the upper thigh portion 50 below the knee, and the second pad region 152 is the thigh portion. The first pad area 150 is in contact with the back side (back side) of the 50, the first pad area 150 is in contact with the upper part of the lower leg 52 (upper part of the calf) on the back side of the leg, and the surface opposite to the bottom surface 100 of the outsole part 10 ( That is, the main surface 102) side contacts the upper portion of the lower leg portion 52 of the knee and the leg. As a result, the area 30 where the band portion 16 contacts the thigh portion 50, the region 32 where the second pad region 152 contacts the rear side of the thigh portion 50, and the main surface 102 or the insole portion 11 of the outsole portion 10 are knees. And / or at least four regions are formed, a region 34 in contact with the upper part of the lower leg 52, and a region 36 in which the first pad region 150 contacts the upper back side of the lower leg 52. Further, in the protective device 1, the pair of sidewall portions 12 come into contact with both side surfaces of the wearer's knee (not shown in FIG. 3). The protective device 1 is fixed to the wearer's knee by integrally contacting and pressing a predetermined portion of the leg including the wearer's knee with these six regions, and the protective device 1 is pressed from the knee when walking on four legs. It can be prevented from slipping or coming off. Further, since at least the region 30 and the region 32 are provided so that the angle with respect to the other region (or the distance from the other region) can be changed, the protective device 1 can be easily brought into close contact with the knee.

For example, when a force in the forward direction is applied to the protective device 1, the band portion 16 makes the protective device 1 follow in the same direction as the applied force. Further, when a force in the rear direction is applied to the protective tool 1, the pad portion 15 causes the protective tool 1 to follow in the same direction as the applied force. As a result, the protective device 1 can maintain a predetermined position around the knee, so that the protective device 1 can be prevented from coming off the knee. Specifically, the band portion 16 contacts the region 30 below the thigh portion 50 above the knee. Then, when a forward force is applied to the protective device 1 (that is, when the wearer lifts the leg forward when moving forward), the forward force is transmitted to the band portion 16, and the band portion 16 receives the force. In the same direction as, that is, the forward force is transmitted to the protective device 1, and the protective device 1 is made to follow the front. As a result, the protective device 1 and the legs move smoothly in the same direction without losing the force generated by the friction between the protective device 1 and the ground (that is, the force that the protective device 1 tries to stay in place). Prevents the tool 1 from slipping backward or downward from the knee. Further, the pad portion 15 comes into contact with the upper part of the lower leg portion 52 below the knee from above the back portion of the knee. Then, when a rearward force is applied to the protective equipment 1 (that is, when the wearer lifts the leg rearward when moving backward), the protective equipment 1 is rearward to the pad portion 15 (particularly, the second pad area 152). The force is transmitted, and the pad portion 15 transmits the force in the same direction as the force, that is, the force to the rear to the protective device 1, and causes the protective device 1 to follow the rear. As a result, the protective equipment 1 and the legs move smoothly in the same direction without losing the force generated by the friction between the protective equipment 1 and the ground (that is, the force that the protective equipment 1 tries to stay in place). It is possible to prevent 1 from coming off the knee forward. That is, the band portion 16 and the pad portion 15 can prevent the protective tool 1 from being displaced due to the force applied to the protective tool 1 in the front-rear direction.

Further, the first band string 13 and the band portion 16 form a V-shaped portion when viewed from the side of the protective device 1. As shown by the alternate long and short dash line in FIG. 4, a V-shape is formed by the band portion 16 and the first partial band string 130 in the side view of the protective device 1 (“V” in FIG. 4). As a result, the protective device 1 can be fixed to the knee against the force applied from a plurality of directions. That is, by forming the V-shape, the upper and lower two regions (the region 30 and the region where the knee and the main surface 102 of the outsole portion 10 contact) and the portion near the back of the knee are formed in the anterior portion of the flexed knee joint. (A region of the first band string 13 between the pair of rotating portions 17) and a total of three regions can be fixed, so that deviation due to knee flexion can be prevented.

Further, when the band portion 16 is not fixed to the sidewall portion 12 but is fixed to the first band string 13 (that is, the positional relationship between the band portion 16 and the first band string 13 with respect to the sidewall portion 12 is Since the position of the band portion 16 with respect to the outsole portion 10 can be changed within a predetermined range in response to the quadrupedal walking motion (when it can be displaced instead of being fixed), the band portion 16 can be displaced from the region 30. Can be prevented. That is, it is possible to prevent the band portion 16 from falling or coming off during four-legged walking. This makes it more difficult for the protective device 1 to come off the knee. Further, since the pad portion 15, the first band cord 13, the second band cord 14, and the outsole portion 10 form a substantially quadrangular prism shape, it is possible to prevent the protective device 1 from rotating back and forth.

Further, the band portion 16 can change the angle with respect to the first band string 13 by the rotating portion 17. Thereby, the position of the band portion 16 can be adjusted to a position where the protective device 1 is hard to be displaced from the knee and is hard to be removed according to the size of the wearer's knee. Since the angle of the band portion 16 can be changed by the rotating portion 17, the band portion 16 changes the angle according to the rise of the band portion 16 when the wearer stands up from the four-crawling state, and the band at the time of rising. It is possible to prevent the part 16 from getting in the way.

(About the slip prevention function by the first band string 13 and the second band string 14)
The first band string 13 and the second band string 14 are provided by a pad portion 15 so as to be separated from each other by a predetermined distance. As a result, when the wearer wears the protective device 1, the first contact portion between the first band string 13 and the back part of the knee and the second band string 14 and the back side of the lower leg (upper part of the calf) are viewed from the side. ), Since the two contact portions of the second contact portion with the) can be provided, the displacement of the protective tool 1 can be sufficiently prevented. That is, if there is only one band string for fixing the protective device to the leg, when a force in the front-rear direction is applied to the protective device, the contact portion (for example, the back of the knee) where the band string and the band string come into contact with each other is centered. When the band string rotates, the entire protective device also rotates back and forth around the back of the knee, and the protective device may shift from the knee and come off. On the other hand, in the protective device 1, since the first contact portion and the second contact portion are present, unlike the case where there is only one band string, there is a portion that can be the central axis of the rotational motion as described above. It is possible to prevent the protective device 1 from rotating in the front-rear direction and slipping off by not being in one place. As a result, even if the protective device 1 is brought into contact with the floor or the like and dragged, it is possible to prevent the protective device 1 from slipping off or coming off from the knee.

<Explanation that the force applied to protective equipment 1 is dispersed>
FIG. 5 shows an example of an outline of a plurality of points of action and a polygon formed by the plurality of points of action of the protective equipment according to the present embodiment. Further, FIG. 6 shows an example of an outline of the force applied to each component of the protective device according to the present embodiment.

The connecting portion between one component of the protective device 1 and the other component, and the portion where the one component and / or the other component contacts the knee or leg are the points of action, respectively. For example, as shown in FIG. 5, the portion 400 in which the first band string 13 is fixed to the outsole portion 10, the band portion 16 and the wearer's leg (the portion in the front part of the thigh above the knee) come into contact with each other. Part 402, part 404 of the rotating part 17 connecting the first band string 13 and the band part 16, part 406 to which the first band string 13 is connected to the pad part 15, and second to the pad part 15. The portion 408 to which the band cord 14 of the above is connected and the portion 410 to which the second band cord 14 is fixed to the outsole portion 10 serve as action points.

Then, in the protective device 1, a plurality of points of action are dispersed throughout the protective device 1, and a polygon connecting the plurality of points of action is formed in the side view of the protective device 1 (dotted line portion in FIG. 5). ). In the protective tool 1, since a polygon in which a plurality of action points are appropriately dispersed (a polygon connecting the action points) is formed, the force applied to the protective tool 1 can be dispersed in various directions. As a result, even if a force is applied to the protective device 1 from a predetermined direction, the force is dispersed in a plurality of directions by the plurality of action points of the protective device 1, so that the protective device 1 can be displaced from the knee or removed. Can be prevented. Then, in the protective tool 1, since the polygonal shape is maintained by each component (that is, the relative positional relationship of each component in the protective tool 1 is maintained), the polygonal shape is deformed. Even so, the restoring force to the original shape works to suppress the displacement of the protective device 1 from the knee.

That is, as shown in FIG. 6, the force applied to the band portion 16 is dispersed in the direction 60a in the direction opposite to the direction 60 and the direction 60, and the force applied to the second pad region 152 is substantially opposite to the direction 60b and the direction 60b. Disperse in the direction 60c. Further, the force applied to the sidewall portion 12 is dispersed in a direction such as the direction 60d, and the force applied to the first band string 13 is dispersed in the directions 60e, the direction 60f, and the direction 60g in the direction opposite to these directions. Further, the force applied to the rotating portion 17 is dispersed in the direction of 60 m. Then, the force applied to the outsole portion 10 is dispersed in the direction 60h or the direction 60i opposite to the direction 60h, and the force applied to the first pad region 150 is dispersed in the direction 60j or the like. Further, the force applied to the second band string 14 is dispersed in a direction such as a direction 60k or a direction 60l. In this way, the force applied to the protective device 1 is dispersed in various directions according to the arrangement of each of the plurality of components constituting the protective device 1. As a result, even if a force is applied to the protective device 1 from various directions, the force is not biased to a part (one direction), so that the protective device 1 can be prevented from slipping off or coming off from the knee.

[Effect of Embodiment]
The protective device 1 according to the present embodiment includes a flat outsole portion 10 having a large contact area with a flat surface such as a floor, and each component (that is, the outsole portion 10, the first The band string 13, the second band string 14, the pad portion 15, the band portion 16, etc.) come into contact with each other from a plurality of directions, and the force applied to the protective device 1 by each component is dispersed in a plurality of directions. Therefore, the protective device 1 has higher adhesion and is less likely to be displaced from the knee as compared with the conventional supporter and protective device, and can improve the stability when the knee is attached to a flat surface. In other words, the protective device 1 can improve the adhesion to the knee by wrapping the knee and contacting the knee from multiple directions. As a result, according to the protective device 1, it is easy to move back and forth and left and right during a four-legged walking exercise, the force applied to the knee can be reduced to prevent the knee and the like from being injured, and the knee portion can be prevented from being sprained and the like.

In particular, with conventional protective equipment such as knee protectors, when the knee joint flexes repeatedly during quadrupedal walking exercise, the protective equipment comes into contact with the ground (particularly, the movement of dragging the protective equipment and the protective equipment touching the ground). The protective equipment was liable to shift in various directions due to repeated movements and / or movements related to friction between the protective equipment and the ground. This is due to the fact that conventional protective equipment does not assume kneeling exercise. In this respect, it is clear from the fact that the conventional protective equipment does not have a planar area corresponding to the ground in the portion corresponding to the outsole portion 10 of the protective equipment 1 according to the present embodiment (conventional protection). In many cases, the tool has a spherical surface or a curved surface that matches the surface of the knee, so it is easy to remove from the part that comes into contact with the ground because it becomes a "point" or "line". Also, the part to be installed is a "point" or "line". Therefore, the protective equipment can be removed by "dragging" the heavy weight.) On the other hand, the protective device 1 according to the present embodiment repeats the flexion motion of the knee joint during the quadruped walking exercise, and even if the wearer's weight is put on and dragged, the protective device 1 can be displaced or removed from the knee. Can be prevented.

Further, in the protective device 1, since the multi-layer structure of the outsole portion 10 and the insole portion 11 can be formed, it is possible to absorb and disperse the impact from the ground (directly below) such as the floor. As a result, the pain in the knee can be reduced in the protective device 1. Further, in the protective device 1, since the angle of the knee with respect to the floor can be fixed by the outsole portion 10 having the surface-shaped bottom surface 100 and the pad portion 15 facing the main surface 102, the possibility of twisting the knee portion can be reduced. .. Further, in the protective device 1, the first band string 13 and the second band string 14 are wound around the knee without taking off the shoes, and the length of each band string is adjusted to adjust the length of the first buckle 135 and the first buckle 135 and the second band string. It can be easily attached to the knee simply by fixing it with the buckle 145 of 2.

The protective device 1 can be used not only for quadrupedal walking exercise but also for prevention of impact on the knee and prevention of injury. For example, protective equipment 1 can be used for gymnastics, dance, outdoor sports, skateboarding, survival games, housework such as cleaning that requires mid-waist work, gardening, camping, strength training, construction / construction work, etc. It may be used for special activities such as disaster relief activities and training thereof.
