DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to lumbar protection for protecting a femur, and more particularly, to a method for preventing a femur from being damaged and a fracture when an elderly man whose bone is weakened due to osteoporosis falls. It is related to waist protection.

[0002]

2. Description of the Related Art Conventionally, there has been provided a protective device for protecting a specific portion of a human body from an impact due to a fall, a collision, or the like. In general, this type of protective equipment is designed so that a fluid such as foam, non-woven fabric, or air made of various resins can be attached to a specific part of the human body as a shock absorbing material, and the part to be protected such as an arm, a chest, etc. Various specifications that conform to the shape have been proposed.

When the lower body is bruised due to a fall or the like, FIG.
A strong impact force acts on the greater trochanter 1a of the femur 1 shown in FIG.
Therefore, when an elderly man whose bones are fragile due to osteoporosis falls down, a part of the femur 1, in particular, the neck 1 b
In many cases, the area near the building is damaged or broken, which has become a social problem in recent years. For this reason, various attempts have been made to protect the greater trochanter 1a and its surroundings (lumbar or hip), among the various parts of the human body.

For example, US Pat. No. 4,573,216 discloses a protector 3 for protecting a waist including a greater trochanter 1a, as shown in FIGS. 28 (A) and 28 (B). I have.
The protective device 3 has a substantially elliptical shape, is made of partially cross-linked silicone rubber, and has an inner layer 3a which is in contact with the surface of the human body 4;
It has a two-layer structure including an outer layer 3b made of a crosslinked silicone rubber. The cross section of the protective device 3 has a bell shape in which the thickness corresponding to the greater trochanter 1a is large and the thickness decreases toward the periphery. The thickness of the inner layer 3a is 40 mm or less, and the inner layer 3a and the outer layer 3
b and the total thickness is 20 to 50 mm.

Further, as shown in FIG. 29, US Pat. No. 5,497,511 discloses a protector 6 made of resin or the like and mounted in a pocket 5a provided in the pants 5. .

[0006] Further, the present applicant has previously filed Japanese Patent Application No.
No. 2520 (Japanese Unexamined Patent Publication No. Hei 8-209409), as shown in FIGS. 30A and 30B, can be attached to pockets 7a provided on both sides of pants 7 and is made of a gel-like substance. Protective equipment 8 is proposed.

Further, US Pat. No. 5,034,998
As shown in FIGS. 31 (A) and 31 (B), a bubble having a large number of concave portions having a circular cross section is provided on a polymer sheet substrate 9 made of an air-blocking polymer material such as polyethylene, polyvinyl chloride or polypropylene. A skirt-shaped protector 12 in which a plurality of fluid chambers 11, 11,... In which a layer 10 is bonded or ultrasonically welded and filled with a gas such as air or a liquid such as water, is disclosed. In FIG. 31 (A), reference numeral 13 denotes a zipper-equipped elastic belt to be attached to the lower body.

[0008]

However, the protective device 3 disclosed in the above-mentioned U.S. Pat. No. 4,573,216 shown in FIG. 28 is a device which protects the greater trochanter 1a and its surrounding parts into one protective device 3a.
Therefore, the surface area (contact area) of the portion in contact with or in contact with the surface of the human body 4 is large. In addition, the protective device 3 has a thickness of 20 to 50 mm as described above. Therefore, the protector 3 cannot sufficiently deform the human trochanter 4 in the greater trochanter 1a and its surrounding area. Therefore, when the protective equipment 3 is worn, the human body 4
Is restricted, and the wearer feels discomfort. In addition, the protection device 3 is relatively heavy in weight, and the wearing feeling is not good in this respect as well.

[0009] Further, US Pat.
The protector 6 disclosed in Japanese Patent No. 97,511 also has a large contact area with the human body and is relatively hard, so that it has poor followability with respect to the movement of the human body and a poor feeling of wearing.

[0010] The protective device 8 according to the present applicant shown in FIG.
Is made of a gel-like substance, and therefore is more flexible than the protective devices 3 and 6 shown in FIGS. 28 and 29. However, since the protective device 8 also has a large contact area with the human body, it cannot be said that the followability to the motion of the human body is sufficient.

US Pat. No. 5,034,9 shown in FIG.
In the protective device 12 disclosed in Japanese Patent No. 98, a large number of fluid chambers 11 are in point contact with the human body, respectively, and the contact area between each fluid chamber 11 and the human body is small. However, when the protective device 12 is worn, the entire front and rear and both left and right sides of the waist are covered with one polymer sheet substrate 9, so that the movement of the wearer is restricted. Further, if the fluid chamber 11 is broken, the gas or liquid filled therein may flow out.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the conventional protective equipment, and has good followability to the movement of the human body and a good feeling of wearing. An object of the present invention is to provide a waist protection device that can be relaxed.

[0013]

In order to solve the above-mentioned problems, a lumbar protector according to the present invention is in contact with at least a portion of a human body surface corresponding to a greater trochanter of a femur and is filled with a gel-like substance. And at least two auxiliary chambers filled with a gel-like substance on the front side of the surface of the human body with respect to the main chamber and having a smaller contact area with the human body than the main chamber. It is characterized by being juxtaposed vertically.

Since the waist protector according to the present invention has the above-described structure, when an impact force acts on the greater trochanter due to a fall of the wearer, the impact force is applied to the gel-like substance in the main chamber. Are absorbed by deformation. Further, when the impact force acting due to the above-mentioned fall or the like acts on a portion ahead of the greater trochanter, it is absorbed by the gel-like substance in the auxiliary chamber. In addition, since the gel-like substance is flexible and has a high degree of adhesion to the surface of the human body, the main chamber and the auxiliary chamber can be deformed following the operation of the human body, and when the human body is in any posture. However, the greater trochanter and its surroundings are reliably covered by the main chamber 33. Further, since two or more auxiliary chambers having a small contact area are provided on the front side of the main chamber, the operation of lowering the upper body to the front and the operation of pulling up the thigh are not hindered, and the wearer does not have to obstruct. These operations can be performed without discomfort.

The above-mentioned gel-like substance is preferably a silicone gel or urethane gel which is excellent in shock absorption. Other gel-like substances include polyvinyl alcohol-based gels, gelatin gels, and acrylic gels.
The gel substance has a hardness (C hardness) of 0 measured by a hardness test method specified in JIS 6050-1988.
It is preferably in the range of about to 40.

The thickness of the main chamber and the auxiliary chamber is preferably 3 mm or more and 10 mm or less. In addition,
If the thickness is less than 3 mm, sufficient impact absorption cannot be obtained. On the other hand, if the thickness exceeds 10 mm, the weight of the waist protection device becomes heavy, and it is not suitable for constant wear.

[0017] The main chamber may be constituted by a plurality of divided chambers closely arranged with each other. In this case, the ability to follow the movement of the human body in the greater trochanter and its surrounding area is further improved.

The peripheral walls of the main chamber and the auxiliary chamber may be made of a urethane resin sheet or a soft vinyl chloride sheet, and an inner layer made of a urethane resin sheet or a soft vinyl chloride sheet, and a knitted and woven fabric. It may be constituted by an outer layer made of ground.

According to the present invention, the main chamber filled with the gel substance and the foam is in contact with at least a portion of the human body surface corresponding to the greater trochanter of the femur, and the main chamber of the human body surface is in contact with the main chamber. An object of the present invention is to provide a waist protector provided with an auxiliary chamber filled with a gel-like substance and a foam on the front side of a site. With this configuration, it is possible to reduce the weight of the waist protector as compared with the case where the entire main chamber and the auxiliary chamber are filled with the gel substance.

The present invention also provides a lower body garment wherein the waist protector is fixedly or detachably mounted. This lower body garment may be lower body underwear worn directly on the skin, or may be worn over the lower body underwear. Specifically, the lower body clothing includes long pants such as briefs, trunks, cycle pants and spats, short pants such as monkey crotch, pants, culottes and skirts.

[0021]

Is obtained by sewing the front body fabrics 22, 22, the side body fabrics 23, 23, and the back body fabrics 24, 24 made of the cotton knit fabric at the sewn portions 26 to 29.
The waist protectors 30, 30 are respectively attached to 23.

As shown in FIG. 6 and FIG.
Numeral 0 is a rectangular thin plate, and has one main chamber 33 and two auxiliary chambers 34, 34 each filled with a gel substance 32 as an impact absorbing material. The wall surfaces of the main chamber 33 and the auxiliary chambers 34, 34
The inner layer 35 is formed of a pair of sheet materials, and a pair of outer layers 3
6, 36 are provided. In the gap between the main chamber 33 and the auxiliary chamber 34 and the gap between the auxiliary chambers 34, the inner layers 35, 35 and the outer layers 36,
Grooves 38a and 38b are provided by fusing 36 and being integrated. Further, the inner layers 35, 35 and the outer layers 36, 36 are also fused and integrated at the outer peripheral edge 39 of the waist protector 30.

The main chamber 33 has a flat rectangular parallelepiped shape, a thickness t1 of 7.5 mm, a length L1 in the vertical direction (vertical direction when mounted on the long pants 21) of 160 mm, and a length in the horizontal direction. L2 is 70 mm. The two auxiliary chambers 34, 34 are arranged side by side in the vertical direction on the side of the main chamber 33. Each auxiliary chamber 34 is a main chamber 3
3 has a flat rectangular parallelepiped shape and a thickness t2 of 7.5 m.
m, the length L3 in the vertical direction is 75 mm, the length L4 in the horizontal direction is 65 mm, and the contact area is smaller than that of the main chamber 33. The width W1 of the grooves 38a, 38b is about 1
0 mm, and the width W2 of the outer peripheral edge 39 is about 5 mm.

As shown in FIGS. 2, 4 and 8, the waist protector 30 is sandwiched between the inner side surface 23a of the side body cloth 23 and the backing cloth 41. It is fixed to the side body cloth 23 by sewing portions 26, 28, 42, 43 formed around. In the groove 38a of the waist protection device 30, a sewing portion 45 for integrally sewing the armpit fabric 23, the waist protection device 30 and the backing cloth 41 is provided.

As shown in FIG. 5, when the long pants 21 are worn, the main chamber 33 covers the greater trochanter 1a of the femur 1 and its periphery as shown in FIG. The auxiliary chambers 34 are set so as to cover a portion on the front side F with respect to the main chamber 33.

The main chamber 33 and the auxiliary chamber 3
The gel-like substance 32 filled in the 4, 34 is an intermediate state between a solid and a liquid, that is, a jelly-like substance having some elasticity. The material is not particularly limited as long as it has such a property as a gel-like substance. As for the hardness, a hardness (C hardness) measured by a hardness test method specified in JIS S6050-1988 is 0 to 40. It is preferable that it is in the range of about. Specifically, the gel-like substance includes silicone gel, urethane gel, polyvinyl alcohol-based gel, gelatin gel, acryl-based gel and the like. Among them, a silicone gel and a urethane gel are particularly preferred in that they have good shock absorption as described later. In the present embodiment, a silicone gel having a C hardness of 5 is used as the gel substance 32.

There are various methods for producing a gel-like substance, such as chemical and physico-chemical methods, but any method may be used as long as desired properties can be obtained. For example, as a method for chemically producing the silicone gel, there is a method in which an organosiloxane having active hydrogen and an organosiloxane having vinyl groups at both ends are partially subjected to an addition reaction. According to this method, the C hardness of the silicone gel can be controlled by the degree of the vinyl group addition reaction. Further, the silicone gel may be foamed for weight reduction.

As described above, the inner layer 35 forms the inner surfaces of the peripheral walls of the main chamber 33 and the auxiliary chamber 34 filled with the gel substance 32 as the shock absorbing material.
Although it is harder than 2, it must be rapidly deformed when an impact force acts and transmit an impact to the gel material 32. Further, the inner layer 35 needs to have an elastic recovery property that quickly returns to the original shape after the impact force has disappeared. Further, the material for forming the inner layer 35 needs to have good processability such as moldability, adhesiveness, and fusibility.
Specific examples of the material that satisfies such conditions include synthetic butadiene rubber, urethane resin, silicone gel, and elastomer materials having rubber elasticity such as polyamide rubber.
There is a sheet material made of soft vinyl chloride or the like. The thickness of the inner layer 35 is about 50 to 500 μm, preferably 100 to 500 μm.
It is preferably from 300 to 300 μm. In this embodiment,
The inner layer 35 is composed of a polyurethane resin sheet having a thickness of 100 μm.

Since the outer layer 36 has a function of reinforcing the inner layer 35, it needs to have a certain strength. Further, since the outer layer 36 constitutes the surface of the waist protection device 30, it is preferable that the outer layer 36 has a good touch. Further, the outer layer 36 needs to have sufficient flexibility so as not to hinder the deformation of the gel material 32 and the inner layer 35. Materials that satisfy such conditions include knitted and woven fabrics, nonwoven fabrics, and synthetic leather. In the present embodiment, the outer layer 36 is formed of a knitted fabric obtained by milling a nylon yarn with a knitted circular knitting machine or the like.

To manufacture the waist protector 30, FIG.
As shown in FIG. 7, polyurethane resin sheets 48 for forming the inner layer 35 are laminated on both sides of a silicone gel plate 47 having a thickness of 5 mm, and an outer layer 36 is further formed thereon.
Knitted fabric 4 with the above-mentioned nylon yarn for forming
9. 49 are laminated. Also, a pair of molds 50A, 50B
In a hot press machine.
And 140 to 2 corresponding to the welding temperature of the knitted fabric 49
Preheat to 00 ° C. Each of the molds 50A and 50B has a recess 5 corresponding to the main chamber 33 and the auxiliary chamber 34.
1 and the projections 52 corresponding to the grooves 38a, 38b and the outer peripheral edge 39. The depth of each recess 51 is 3.5 mm
And the depth of the closed space formed when the dies 50A and 50B are overlapped is set to 7.0 mm.

Next, the polyurethane resin sheet 48
Gel plate 47 in which a knitted fabric 49 is laminated
Is inserted between the molds 50A and 50B in the heat press machine, and as shown by an arrow A in FIG.
Molds 50A and 50B are pressed from both sides of the mold.

By this hot pressing, both dies 50A,
The silicone gel plate 47 is divided at the portion sandwiched by the convex portions 52 of 50B, and the gel-like substance is extruded into the closed space sandwiched by the concave portions 51, 51. Therefore, the volume of the gel-like substance increases in the space between the concave portions 51, 51, and the polyurethane resin sheet 48 and the knitted fabric 49 expand. In the portion sandwiched by the protrusions 52, the polyurethane resin sheet 48 and the knitted fabric 49 are fused and integrated with each other to form the main chamber 3.
3 and a groove 38a closing the periphery of the auxiliary chamber 34,
38b and the outer peripheral edge 39 are formed.

As shown in FIG. 5, when the long pants 21 are worn, the greater trochanter 1a of the femur 1 and its periphery are covered by the main chamber 33 having a large contact area. Therefore, even when the wearer falls and the impact force acts on the portion corresponding to the greater trochanter 1a of the human body 4, the impact force is absorbed by the deformation of the gel-like substance 32 in the main chamber 33. . In addition, two auxiliary chambers 34, 34 are arranged at a position on the front side F of the femur 1. Therefore, even when the impact force acting due to the above-mentioned overturning is used in a portion distant from the greater trochanter 1a, the impact force is absorbed by the gel-like substance 32 of the auxiliary chambers 34, 34 and transmitted to the greater trochanter 1a Is reduced.

The gel-like substance 32 filled in the main chamber 33 and the auxiliary chambers 34, 34 as a shock absorbing material as described above is more flexible than a rubber elastic material, a foam, etc. High adhesion. Therefore, the main chamber 33 can be deformed following the movement of the human body 4, and the periphery of the greater trochanter 1 a is reliably covered by the main chamber 33 regardless of the posture of the human body 4.

Further, as described above, the gel-like substance 32 is soft and has a good tactile sensation. Therefore, the waist protector 30
The wearing feeling of the long pants 21 is better than that of a case in which a waist protector made of a rubber elastic material, a foam, or the like is provided. Further, even when the inner layer 35 and the outer layer 36 are broken at the time of wearing, the gel-like substance 32 hardly flows out of the main chamber 33 and the auxiliary chamber 34 as compared with the case of gas or liquid.

Further, as described above, the auxiliary chambers 34, 34 having a smaller contact area than the main chamber 33 are vertically arranged at the anterior portion of the femur 1 as shown in FIG. 5, the operation of tilting the upper body 4a forward as shown by the arrow B and the operation of pulling up the thigh 4b as shown by the arrow C in FIG. 5 are not hindered. Therefore, the wearer of the long pants 21 can perform these operations without discomfort.

Further, since the contact area of the main chamber 33 is set large, the position of the greater trochanter 1a may differ due to a slight shift in the mounting position of the waist protector 30 or a difference in the body shape of the wearer. Even if there is, the greater trochanter 1 a and its peripheral portion are covered by the main chamber 33. Furthermore, even if the greater trochanter 1a is not covered by the main chamber 33, it is covered by the auxiliary chamber. As described above, the long pants 21 equipped with the waist protection device 30 of the present embodiment are
a can be reliably protected from an impact such as when it falls down, and the follow-up to the operation and the feeling of wearing are good.

As shown in FIG. 3 to FIG. 5 and FIG. 10, the rear body cloths 24, 24 cover the buttocks 4c of the human body 4,
Buttocks protectors 52, 52 are mounted. Hip protection equipment 5
2 is sandwiched between the inner side surface 24a of the back body cloth 24 and the backing cloth 53, and the backing cloth 53 is a sewn portion 2 formed around the backing cloth 53.
8, 29, 54, 55 are fixed to the back body cloth 24. In addition, a sewing portion 57 for integrally sewing the back body cloth 24, the buttocks protection device 52, and the backing cloth 53 is provided.

Since the buttocks 4c of the human body 4 are in close contact with the seated portion when seated, it is necessary to pay attention to stuffiness and touch. Therefore, it is desirable that the buttocks protector 52 be formed of an elastic body having a high air permeability and flexibility. Specifically, it is preferable to use an elastic body such as a thermoplastic elastomer foam, an acrylic foam, or a polyurethane rubber. In the present embodiment, the buttocks protector 52 is formed of a flat body made of polyurethane rubber. If such a buttocks protector 52 is provided, it is possible to protect the ischial bone when it falls down and the buttocks 4c are bruised on the ground or the like. The buttocks protector 52 may be made of a flat body in which the chamber is filled with a gel-like substance, as in the case of the waist protector 30 described above.
