Description

The present invention relates to a shock absorbing device capable of avoiding fractures and severe muscle damage caused by falls, hips, etc. by covering the waist and buttocks of the human body as widely as possible.

Recently, snowboarding and skateboarding have become widespread among young people as a type of sport and with the diversification of play. Since these snowboards and skateboards compete for complicated techniques at a fairly high speed during competition and play, they may break the lumbar region or buttocks due to a fall, or even damage the muscles even if they do not break. May be forced into long-term treatment.

On the other hand, looking at the elderly, there are many cases in which elderly people who have difficulty walking have fractures or muscle damage due to postures such as sticking to their hips or twisting their hips.

Patent Document 1 discloses a shock absorbing device that can avoid compression fractures caused by rehabilitation of the elderly and stickiness of the hips.

Further, Patent Document 2 describes a pocket or bag for storing a shock absorbing pad inside clothing such as trousers and skirts that the wearer wears on a daily basis in order to avoid a fracture of the proximal femur of an elderly person. Shock absorbing padded garments with a body are disclosed.

Japanese Unexamined Patent Publication No. 2012-95878 Utility Model Registration No. 3208287

The areas where elderly people fall and fracture or damage their muscles are not uniform. Similarly, the locations of fractures and injuries caused by falls in sports that young people enjoy, such as snowboarding and skateboarding, are widespread.

The mounting position of the shock absorbing pad disclosed in Patent Document 1 and Patent Document 2 is limited, and it cannot be said that all fractures and fall accidents can be dealt with.

The present invention is designed to overcome the problems of the above-mentioned conventional technique, and avoids fractures and muscle damage in the widest possible range when the person has a sticky back or falls, or the degree of damage thereof. It is an object of the present invention to provide a shock absorbing device capable of slightly suppressing the above.

In order to achieve the above-mentioned object, according to the shock absorbing device according to the present invention, a sacral pad that mainly protects the sacral bone, a tail bone pad that mainly protects the tail bone, and a pair of thighs that mainly protect the femoral head. A pad for the head of the bone, a set of pads for the trochanteric region that mainly protects the trochanteric region of the femoral bone connected to the head of the femoral bone, a set of pads for the scrotum / sciatic bone that mainly protects the sciatic bone / sciatic bone, and a femoral bone. It is provided with a femoral pad that mainly protects, and the sacral pad and the tail bone pad are foldably connected to each other, and the sacral pad is foldably connected to a set of femoral head pads. The trochanteric pad is foldably connected to the scrotum / sciatic pad and the femoral pad that protects the upper part of the femoral bone, and the tailbone pad is foldably connected to the scrotum / sciatic pad. Further, a set of the femoral head pad and the scrotum / sciatic pad are foldably connected to each other.

In this way, the sacrum, tailbone, femur head, pubis including the large trochanter, pubis / ischium including the ischium and the ischium connected to the pubis, and the femur itself are protected in the skeleton from the lumbar region to the buttocks of the human body. It has a pad to do. With such a configuration, it is possible to avoid damage to the gluteus maximus muscle of the trochanteric portion from the femoral head and the muscle of the upper part of the hamstring from an accident such as a fall.

In particular, since the protective pads corresponding to the head, trochanter, and pubis / ischium in the skeleton are foldably connected to each other, the protective pad follows the movement of each bone and muscle. Since it bends, the protective pad also displaces according to the movement of the body in the event of an accident such as a fall or pubic stick. Therefore, since the protective pad flexibly responds to the movement of the skeleton and muscles, it can perform a protective function of softly receiving the impact applied to the skeleton and muscles.

In addition, the greater trochanter that constitutes the trochanter and the gluteus maximus that covers the trochanter can be bent by connecting the protective pads to each other according to the lower part of the trochanter. Damage to the skeleton and muscles above the hamstring can also be avoided.

Moreover, according to the present invention, the trochanter pad is divided into a greater trochanter pad and a trochanter lower pad, and protection that can faithfully follow the greater trochanter and the lower trochanter that are greatly displaced during a fall. It is configured to achieve its function. Therefore, damage to the gluteus maximus muscle in addition to the greater trochanter and the lower part of the trochanter can be avoided or the degree of damage can be reduced.

Further, according to the present invention, the sacral pad, the coccyx pad, and the tail bone pad are connected by a triangular joint piece, and the long piece of the joint piece is bent with each side of the femoral head pad and the pubic / ischial pad. It is freely connected. As a result, when the sacrum, coccyx, and femoral head fall, for example, even if the lumbar region and buttocks are twisted, the pads follow and deform in different directions due to the difference between the two angles of the joint piece. do. This also prevents fractures and injuries of the femoral head, trochanteric region, pubis, ischium, and femur.

In addition, if the pad has a two-layer structure of foam materials with different elasticity and the foam material on the outside when viewed from the human body has a larger elasticity, the soft foam material comes into contact with the body and an impact is applied. Since the foam material having a strong elastic force directly receives the load, the load on the human body can be further weakened. In particular, the hardness of the femoral pad is preferably higher than the hardness of the sacral pad, the coccyx pad, the femoral head pad, the trochanteric pad, and the pubic / ischial pad. This is to further avoid fractures and injuries due to the load applied to the femur when the hips are held or fall.

As described above, according to the present invention, even elderly people and even young people can avoid or reduce the degree of fractures and muscle damage caused by fall accidents, etc. The effect that can be obtained is obtained.

The shock absorbing device 10 that surrounds and flexes the skeletal structure as described above will be described in detail in relation to the pad.

As shown in FIGS. 4 to 6, the sacral pad 40 that constitutes the shock absorbing device 10 and protects the sacrum 22 has an arcuate top portion, and ends substantially parallel to the portion where the arcuate portion 42a terminates. After the edges 42b and 42c extend downward in FIG. 4, they are connected to the linear end edges 42d and 42e, and these edge edges 42d and 42e are connected to the lateral edge portion 42f.

The bottom of the coccyx pad 50 constitutes an arc portion 52a, and the end edges 52b and 52c rise upward substantially parallel to the portion where the arc portion 52a ends, and the linear end edges 52d from each end portion. , 52e extend so as to approach each other and are connected to the lateral edge portion 52f.

The lateral edge portion 42f and the edge portion 52f are sutured at a connection site with each other as described later, and the sacral pad 40 and the coccyx pad 50 are foldably integrated with each other.

A connecting piece 60a made of a triangular pad is foldably connected between the end edge 42d of the sacral pad 40 and the end edge 52d of the coccyx pad 50. Similarly, a connecting piece 60b made of a triangular pad is foldably connected between the end edge 42e of the sacral pad 40 and the end edge 52e of the coccyx pad 50.

As a result, as can be easily understood from FIG. 4, the sacral pad 40, the coccyx pad 50, and the long sides 62a and 62b of the triangles of the connecting pieces 60a and 60b have an oval shape as a whole.

Next, the femoral head pad 70 that is flexibly connected to the sacral pad 40, the coccyx pad 50, and the joint piece 60a will be described.

As can be seen from FIG. 4, the femoral head pad 70 is formed in a deformed rectangular shape when viewed from the front. The top edge 72a has a slightly curved shape, while the other edges 72b, 72c, 72d are linear, and the edge 72c is the edge 42b of the sacral pad 40, the long side 62a and the coccyx of the connecting piece 60a. It is freely bent and connected to the edge 52b of the pad 50.

The pad 80 for the trochanter portion is divided into a pad 82 for the greater trochanter portion and a pad 84 for the lower portion of the trochanter, and the pad 82 for the greater trochanter portion extends from the end edge 86a having a curved side and the end edge 86a. It has a shape close to a deformed fan shape with edge edges 86b and 86c consisting of two sides converging at the terminal portion. The linear edge 86c is foldably connected to the edge 72b of the femoral head pad 70.

As shown in FIG. 4, the trochanter lower pad 84 constituting the trochanter pad 80 has a deformed trapezoidal shape, and has an end edge 88a composed of long sides and an end to tip of the end edge 88a. It is composed of an edge edge 88b, 88c extending in a direction in which the portions converge with each other, and an edge edge 88d connecting the two edge edges 88b, 88c.

The edge 86b of the pad 82 for the greater trochanter and the edge 88b of the pad 84 for the lower trochanter are foldably connected to each other.

A pubic / ischial pad 90 is arranged between the lower trochanter pad 84 and the coccyx pad 50. As shown in the figure, the pubic / ischial pad 90 has a deformed square shape when viewed from the front, and the end edge 92a extending linearly for a long time can be freely bent to the end edge 72d of the femoral head pad 70. Be concatenated. The edge 92b extending in an acute angle from one end of the edge 92a is foldably connected to the edge 88d of the trochanter lower pad 84. The edge 92c extends substantially parallel to the edge 92a from the end of the edge 92b, and the respective ends of the edge 92a and the edge 92c are continuous with the arcuate edge 92d.

The femur pad 100 for protecting the femur body is foldably connected to the trochanter lower pad 84 and the pubic / ischial pad 90. That is, the femur pad 100 exhibits a deformed fan shape when viewed from the front, and one linear end edge 102a is foldably connected to the end edge 88c of the trochanter lower pad 84. The other linear edge 102b is flexibly connected to the edge 92c of the pubic / ischial pad 90. The arc-shaped end edge 102c is continuous between the end portions of the end edge 102a and the end edge 102b.

In FIGS. 4 and 5, the same reference numerals indicate the same members or parts, and detailed description thereof will be omitted. This is to avoid complicated explanations.

Next, the configuration of the pads constituting the shock absorbing device 10 will be described.

In the embodiment of the present invention, the sacral pad 40, the coccyx pad 50, the joint pieces 60a and 60b, the femoral head pad 70, the greater trochanter pad 82, the trochanter lower pad 84, the pubic bone / ischium. The pad 90 has a two-layer structure of polyurethane foam materials 200a and 200b, and when the half pants 14 are worn, the foam material 200a on the human body side (inside) is selected to have a lower hardness than the outer foam material 200b. is doing.

On the other hand, the pad 100 for the femur is made of a foam material 500a made of polyurethane on the inside and a foam material made of EVA (Ethylene-Vinyl Acetate, ethylene vinyl acetate) 500b on the outside. As is well known, EVA500b is selected to have a higher hardness than polyurethane, so that the load is extremely increased during a fall or when the hips are held. Is even more effective.

Next, a method of manufacturing the shock absorbing device 10 according to the present invention will be described.

First, a first skin 300 made of polyester having a similar shape larger than that of the shock absorber 10 shown in FIG. 4 was prepared, and foamed materials 200a and 200b (see FIG. 6) were laminated and formed on the first skin 300. Pad 40 for sacrum, pad 50 for coccyx, joint pieces 60a, 60b, pad 70 for femoral head, pad 82 for greater trochanter, pad 84 for lower trochanter, pad 90 for pubis / ischium are spaced apart from each other. Place and position as shown in FIG. 4 with a narrow distance. In addition, the laminated body of the foam material 500a and EVA500b shown in FIG. 7 is placed and positioned corresponding to the pad 100 for the femur. Next, a second skin 400 made of the other polyester is placed on the upper surface thereof.

After mounting in this way, the circumference of the sacral pad 40 to the femur pad 100 is sutured with an automatic sewing device, and the outer peripheral edge thereof is trimmed to obtain the shock absorbing device 10 as a finished product.

Next, an application example in which the shock absorbing device 10 according to the present invention is used to avoid a fracture or the like in an elderly person will be described below.

A pocket 700 having a similar shape larger than that of the shock absorber 10 is arranged in advance on the rear portion 706b (dorsal side) of the half pants 14. Preferably, a stretchable fabric is used for the fabric of the pocket 700, an opening (not shown) is provided in a part of the pocket 700, and the shock absorbing device 10 is taken in and out of the pocket 700 from the opening to absorb the shock. The device 10 can be attached and detached. Alternatively, a fastener (not shown) is provided on one side (or both sides) of the pocket 700, and the shock absorbing device 10 can be attached to and detached from the pocket 700 by opening and closing the fastener.

On the other hand, a pair of cuts 702a and 702b extending from the waist to the lower part of the thigh of the human body 12 are provided on both sides of the front part of the half pants 14, and the cuts 702a and 702b can be opened and closed with respect to these cuts 702a and 702b. The fasteners 704a and 704b are sewn together. The cuts 702a and 702b divide the shorts 14 into a narrow front 706a and a wide rear 706b. However, the front portion 706a and the rear portion 706b are connected by the tail bottom portion 706c of the half pants 14.

Male snap buttons 708a and 708b are provided at the corners of the front portion 706a of the half pants 14. When the fasteners 704a, 704b are closed, the male snap buttons 708a, 708b are fastened to any of the female snap buttons 710a, 710b provided at the corners of the rear 706b of the shorts 14. The selection of snap buttons 710a and 710b depends on the thickness of the abdominal circumference. Therefore, the front portion 706a and the rear portion 706b of the half pants 14 are integrated and can be dressed so as to surround the waist portion of the human body 12.

On the other hand, when undressing the shorts 14, first, the male snap buttons 708a and 708b and the female snap buttons 710a and 710b are separated from each other, and then the fasteners 704a and 704b are pushed down to open. As a result, the front portion 706a is separated from the rear portion 706b of the half pants 14.

That is, even when the human body 12 is lying on its back, the half pants 14 equipped with the shock absorbing device 10 can be separated from the human body 12 by simply lifting the waist portion a little. In particular, the shock absorbing device 10 can be removed from the human body 12 even if the elderly person in a sleeping state is not standing. Therefore, if necessary, the shock absorbing device 10 can be taken out from the pocket 700 of the shorts 14 and used for washing or the like.

Needless to say, when the shock absorbing device 10 is attached to the half pants 14 by suturing or the like, the device may be used for washing or the like together with the half pants 14 without being detached from the half pants 14.

Needless to say, the half pants 14 do not need to be provided with the pocket 700 or the shock absorbing device 10 when they are not required. For example, when there is little possibility of a fall, etc., while an elderly person wearing a diaper due to concerns about urine leakage or the like uses only the half pants 14, the half pants 14 will have the front part 706a from the rear part 706b while lying down. There are also advantages such as easy replacement of diapers by opening.
