Description

    The present invention relates to a clothing with an elastic member suitable for being applied to clothing such as an apron.

    At present, there are many people who have a hard feeling due to low back pain. Especially in agricultural work, there are many difficult attitudes to bend forward. These are likely to become even more important issues in the age of aging.

Among the farm work, the work of hoe is planting, harvesting, and care and almost manual work. Moreover, in the rice field work, although rice planting and rice harvesting have been mechanized, weeding between rice stocks is a manual work because there is no suitable machine. In addition, pesticides whose toxicity is a problem are in a situation where manual labor is indispensable for organic farming methods that do not use as much as possible.
JP 10-46409

An object of the present invention is to provide a clothing such as an apron that can be easily worked in a forward bending operation such as farm work, a forward bending operation in nursing care, and a forward bending operation in a general manufacturing industry.

What is shown in the above-mentioned document is that the degree of waist tightening for back pain can be adjusted, and a method and an example that can easily bend forward are not disclosed.

As shown schematically in FIG. 1, the present invention has an elastic member 1 disposed at the front of the human body, and when bent forward, the upper body is supported by the lower body of the thigh or the like to reduce the burden on the waist. It is.

An elastic member such as a spring steel material has a drawback in that as the waist is bent, the stress increases in proportion to the displacement of the spring, and a strong force is applied to the upper body. Here, the shape memory alloy will be described. Shape memory alloys have superelastic properties. The characteristic is that the stress does not increase beyond a certain displacement. It is well known that the spring material is difficult to be permanently deformed and returns to its original shape even when deformed, and is used for an antenna of a mobile phone by utilizing these effects. In the present invention, the use of a shape memory alloy as an elastic member makes use of the property that stress does not increase beyond a certain displacement, and no matter how much you bend, the upper part of the body, such as the chest, does not apply any force. Can ease the above-mentioned drawbacks. However, it is a problem that the shape memory alloy is expensive, and it is necessary to consider effective utilization.

The present invention has greatly facilitated farm work that requires forward bending. It can also be used in nursing care sites where there is a lot of bending work, it can also be used for housework such as cooking and washing, it is also effective for long-time work that leans forward at the manufacturing site, and it is also useful for correcting the child's learning posture . Furthermore, when the same structure is applied to the corset, it can be worn on the body at all times, and the effect of preventing low back pain can be further obtained.

When the inventor actually tried the apron with the elastic member as a shape memory alloy, there was no problem such as pain in the waist with a forward bending posture of 10 minutes, and in the apron not applying this, the waist and upper and lower limbs in 5 minutes I felt pain in the department.

Further, actual measurement values are shown.

Fig. 2 is a schematic diagram showing the posture of the human body, (X) is an upright posture with both feet, (Y) is a forward-bend posture without wearing an apron, and (Z) is a forward-bend posture with an apron It is. At this time, the average values and fluctuations of the numerical values read from the graph in which the muscle strength values of points A and B, which are calf muscles, are measured with reference to point C are shown in the following table.

From this, it can be seen that the muscle strength value doubles from 0.48 to 1.00 when the apron is not worn, when bending forward with respect to standing with both feet. However, when wearing an apron, the value drops by 20 percent from 1.00 to 0.80 compared to when not wearing it. In addition, the fluctuation representing the tremor resulting from muscle fatigue was inevitably larger at ± 0.17 when bent forward than when standing upright, but decreased by about 40% to ± 0.11 when wearing an apron. Thus, a remarkable effect was obtained.

Fig. 3 is a graph showing actual measured values.

The present invention may also be used for apron and tie clothes. In the case where the jacket is divided into an undergarment, the same effect can be obtained by providing pocket portions for accommodating the sheathed elastic members of the present invention.

The case where the elastic member of the present invention is applied to an apron as a shape memory alloy member will be described.

FIG. 4 is an explanatory diagram showing a portion where the shape memory alloy member is inserted into a hollow stainless steel tube before the shape memory alloy member is attached to the apron.

In FIG. 4, 1 is a shape memory alloy member. In this example, four shape memory alloy wires having a length of 490 mm and a diameter of 2 mm are used. 2a and 2b are hollow bodies into which the upper part and the lower part of the shape memory alloy member 1 are inserted. In this example, 2a is a stainless tube having a length of 200 mm, and 2b is a stainless tube having a length of 140 mm. Reference numerals 3a and 3b denote drop prevention plugs provided on the stainless pipes 2a and 2b where the shape memory alloy member 1 is not inserted. The shape memory alloy member 1 can be taken in and out by removing the drop prevention plugs 3a and 3b, and the strength of the spring can be adjusted for each wearer by changing the number and diameter thereof.

5a and 5b are spacer pieces inserted between the fall prevention plugs 3a and 3b and the shape memory alloy member 1, which can move the bending position 11 of the shape memory alloy member 1, and the shape memory alloy member 1 When the effect could not be obtained due to fatigue deterioration, the effect could be obtained sufficiently by placing the newly undisplaced part in the bending position.

In addition, the length 11 of the portion where the shape memory alloy member 1 is displaced, that is, the portion where the shape memory alloy member 1 is exposed between the stainless steel tube 2a and the stainless steel tube 2b is 210 mm. It will be displaced. Of course, if it is too long, the sense of stability is impaired.

FIG. 5 is an explanatory diagram when the shape memory alloy member 1 is inserted into the stainless steel pipes 2a and 2b and attached to the apron 5, and two sets are used on the left and right. One set is sufficient for short-time work.

6 is a plastic plate having a thickness of 1 to 2 mm inserted between the apron 5 and the sheath, and can distribute the pressure on the body over a wide area.

7 is a neck strap, and 9a and 9b are tightening straps around the waist.

Fig. 6 shows an example in which the shape memory alloy member 1 and the stainless steel tubes 2a and 2b are placed in a cloth sheath 8. The upper part (corresponding to the stainless steel tube 2a) is the chest and the lower part (corresponding to the stainless steel tube 2b). Put it on the thigh. The portion where the shape memory alloy member 1 is exposed is a range of displacement due to the superelastic characteristics of the shape memory alloy member 1, and is preferably located at the hip joint portion. There is also an effect that both ends of the sheath can be adjusted to the optimum position of the user. Further, since the upper and lower ends of the sheath are open so that the shape memory alloy member 1 and the stainless tubes 2a and 2b can be taken in and out, they can be exchanged.

FIG. 7 shows an example in which the sheath has an inverted Y-shaped bifurcated structure, and if it is placed on both sides of the thigh, lateral slip can be prevented. At this time, it is better to divide into two branches and make the branch below the ribs. At this time, the shape memory alloy member 1 does not climb up against gravity due to the action of the spacer piece 5a.

FIG. 8 shows an example in which the sheath is inverted V-shaped. As shown in FIG. 7, when the shape is an inverted Y shape, the smoothness of the slide of the shape memory alloy member in the hollow body is lost, and the shape memory alloy member slides up above the chest, and a sense of pushing up occurs. However, if this is an inverted V shape, there is no such thing because it splits into two forks from the top of the chest and goes straight down to the thigh.

The upper part of the sheath is sewn to the apron 5 in FIG. 5 or fixed with a hook so that it can be detached.

The lower part of the sheath is inserted into pockets 4a and 4b provided at the position of the thigh of the apron 5, and the lower part of the sheath itself can be folded back, and the length can be changed according to the height. When the sheath is bifurcated, the distance between 100 mm and 120 mm is suitable.

Further, as shown in FIG. 9, a pocket may be provided in a second member other than the apron pocket, for example, a supporter 10 slightly wrapped around the thigh, and a sheath may be inserted therein.

Also, when the knee is in close contact with the chest and the stress of the shape memory alloy member becomes a burden, the forward bending posture continues, as shown in Fig. 10, the spring force does not work by taking the lower part of the sheath out of the apron Can work easily. When used as an ordinary apron without a shape memory alloy member, the upper part of the sheath is also made removable.

FIG. 11 is an explanatory diagram when the apron 5 is actually attached to the body.
