DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended to provide a heat retaining function to clothes including underwear such as under trousers and shirts, pajamas, sportswear, sweat suits, spats, pantyhose and the like. Related to warm insulation clothing.

[0002]

2. Description of the Related Art Conventionally, most winter clothing is manufactured using a thick cloth as a fabric itself. However, it has a drawback that it is heavy and difficult to move. Therefore,
For example, in Japanese Utility Model Publication No. Sho 62-180004, pajamas are taken as an example, and only a portion that does not overlap with underwear, that is, a different cloth is sewn to joints such as knees and elbows and shoulders, etc. It is described that heat is kept while preventing the whole from becoming too heavy.

[0003] Since the sewing position of the above-mentioned separate material is mainly made to correspond to a joint or the like, it is preferable to apply a lattice-like or parallel-line quilting over the entire surface of the different material. It becomes suitable.

[0004]

As described above, conventionally,
The sewing site of another fabric is determined from the viewpoint of "the site that does not overlap with the underwear", and there is no firm basis for positioning the different fabric. Therefore, the size of the different dough and its positioning vary depending on the product type and the manufacturer, and some of them do not have a sufficient heat retaining effect.

[0005] Regarding the above-mentioned conventional garments, dissatisfaction with the heat retention effect tends to occur more easily as the age increases. On the other hand, when examining clothing which was considered to be insufficient in heat retaining effect, it was found that most of the clothing was sewn with a different fabric to the body fabric by quilting. From this, it is assumed that the quilting has many seams and the overall thickness after sewing becomes small, so that heat may be easily radiated.

However, for example, when another cloth is attached by a method such as bonding, when the positioning is made to correspond to the joint, there is a drawback that the comfort and movement are deteriorated. . The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a thermal insulation garment capable of surely retaining heat without deteriorating comfort and movement.

[0007]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, in the thermal insulation garment according to the present invention, in the garment having the left and right tubular portions (2) wrapping the thighs, the left and right tubular portions are provided.
These left and right corresponding to only the front part of the thigh in (2)
A piece of cloth having a heat insulating material on the inner surface of the cylindrical portion (2)
Insulation member (3) made of the dough pieces
By sewing the outer periphery of the member (3),
The material (3) is made invisible from the outside so that the heat insulating member
An air layer is formed between (3) and the inner surface of the cylindrical portion (2).
And it is characterized in that it is (claim 1). Here, in the present invention, the positioning of the heat retaining member 3 has a firm basis.

[0008] That is, humans maintain their body temperature at a constant level by increasing their sweating ability and skin blood flow when the environmental temperature rises or when exercising. However, these sweating ability and skin blood flow are aging. It decreases with. That is, such a decrease in the body temperature regulation function also means a decrease or slowdown of the function of preventing a decrease in the body temperature when the environmental temperature is decreased.

FIG. 50 shows the results of examining the body temperature holding ability, that is, the thermoregulatory response under cold exposure, for 9 males in their 20s and 10 males in their 60s. The environmental conditions were as follows: After maintaining the chair in a resting state (equilibrium period) for 60 minutes in a front room adjusted to a constant of 28 ° C., the room temperature was assumed to be spring or autumn.
° C, humidity 45% R. H. Exposure for 60 minutes in an artificial climate chamber with a room temperature of 12 ° C and a humidity of 45% assuming winter
R. H. When exposed for 60 minutes in an artificial climate chamber,
Two scenes were set. The subject's clothing was one swimming pants of the same type. The results were determined by measuring the rectal temperature and the average skin temperature after cold exposure for each scene.

[0010] The subjects were selected from electrocardiograms, urinalysis,
The condition was such that there was no abnormality in blood pressure and the like, and care was taken so that there was no group difference in body fat percentage and volume surface / mass. As is apparent from FIG. 50, it can be concluded that the elderly are inferior in body temperature retention ability as compared to the young adults. On the other hand, the above-mentioned decrease in sweating ability and skin blood flow is started from the lower limbs, then moves to the back, the front, and the head of the trunk (which is a torso, in a broad sense). In addition, due to the highest heat radiation efficiency of the thighs among the lower limbs, it was found that the decrease in skin blood flow and sweating ability in the thighs occurred more remarkably in the elderly than in young adults. ing.

FIG. 51 shows the results of examining the aging characteristics of the same subject at the time of the above-mentioned examination of the body temperature holding ability due to differences in body parts. The clothing of the subject is also the same as above. The environmental conditions were as follows: After maintaining the chair in a resting state (equilibrium period) for 60 minutes in a front room adjusted to a constant of 28 ° C., the room temperature was 35 ° C. and the humidity was 45% R.H. H. And a lower limb warm bath with hot water of 42 ° C. was performed in the artificial climate room of the above. The results were determined by measuring blood flow and sweating after the lower limb warm bath.

As is evident from FIG. 51, the blood flow rate and the sweat rate of the elderly are generally lower than that of the young adult, and the blood flow rate and the sweat rate decrease for each body part. You can see that there is. In addition, as one consideration obtained at the time of this measurement, it has been recognized that the decrease in the amount of sweat in the elderly is not a decrease in the number of active sweat glands but a decrease in sweat output in a single sweat gland.

The document in FIG. 51 is based on “Aging mechanism of skin blood flow in hot environment; age-related decrease in skin blood flow in hot environment” in “Osaka Gas Group Welfare Foundation Research Report 8”. Examination from Differences in Body Parts ", Author: Yoshimitsu Inoue,
They are Tsutomu Araki, Manabu Shibasaki and Kozo Hirata (issued in 1995).
For this reason, in the present invention, first, the heat retaining member is provided corresponding to the thigh.

[0015] Conventionally, with regard to clothes sewn with different fabrics, there has been a tendency that dissatisfaction with the heat retention effect tends to occur in the elderly or the like. Then it will be easily understood. When the heat retaining member is provided for the tubular portion surrounding the thigh, it is preferable that the heat retaining member is provided on the inner surface of the tubular portion in that the heat retaining effect can be directly transmitted to the skin. Also, in this way, the fabric facing outward becomes the body fabric itself, so in appearance,
There is also an advantage that there is no discomfort due to the provision of the heat retaining member.

Attachment of the heat insulating member to the cylindrical portion
Sewing or bonding may be used, and a detachable structure using a hook-and-loop fastener or the like is also conceivable. For example, in the case of sewing, if quilting sewing or the like is employed, the air layer formed between the heat retaining member and the inner surface of the cylindrical portion is subdivided, which is not very suitable for enhancing the heat retaining property. since it can not be said, in the present invention, it is sewing and wearing only the outer peripheral portion of the heat insulating member
This keeps the insulation from being visible from outside
It will be.

Further, in the present invention, it is composed of a dough piece.
It is recommended that the insulation be rectangular.
Claim 2). In addition, in claim 1 or 2, before the cylindrical portion.
Approximately the width of the heat insulating member in the width direction
It is recommended that the angle be about 150 °.
3).

If the heat retaining member is extended to a height corresponding to the knee, a person suffering from joint pain can further enhance the heat retaining effect. On the other hand, the present invention can be applied not only to pants-type so-called lower-level clothing but also to so-called upper-level clothing having a part surrounding the upper body. In this case, the heat retaining members are provided while forming air layers at both corresponding left and right portions from the front surface to the rear surface of the shoulder.

That is, in the present invention, the part wrapping the upper body
And at least the lower body, including the thighs,
A part that wraps the upper body in clothing that has a body or separate upper and lower parts
The left and right garments correspond from the front to the back of the shoulder.
Provide heat insulation members on the inner surface of both parts
By sewing the outer periphery of the heat insulating member, the heat insulating member
The heat insulation member and both left and right parts
Forms an air layer between the inner surface of the body and wraps the lower body
The clothing is the clothing according to any one of claims 1 to 3.
(Chart 4) . In claim 4, the height dimension at which the heat insulating member is provided at the left and right front side portions and the left and right rear portion portions is 5 to 30 cm.
(Claim 5 ). As described above, in consideration of the fact that the skin blood flow and the sweating ability decrease from the lower limb to the posterior surface of the trunk and the anterior surface of the trunk, even in this range, the heat radiation efficiency is relatively high, and the shoulder (see FIG. 51) is provided. As is apparent from this, in clothing such as pajamas, which has a part wrapping the upper body or a part wrapping the half body as an integral part or upper and lower parts, the corresponding parts of the shoulder and the thigh are used, and What is necessary is just to provide a heat retention member, forming an air part. By doing so, the area where the dough has a double structure can be minimized,
Therefore, no problem occurs with respect to weight and ease of movement.

Therefore, in the case of the elderly, it is difficult to move the body even if the body is moved, and it is difficult for the elderly to move substantially with swelling and the like. It is something that can be prevented from being done.

[0021]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment of a warm clothing 1 according to the present invention. The thermal insulation garment 1 of the first embodiment is applied to a so-called "lower item" having a tubular portion 2 wrapping a thigh. Specifically, it is under the pants of a short pants type which is a kind of underwear, and the cylindrical portion 2 is formed with a skirt around.

In the heat-insulating garment 1, heat-insulating members 3 are provided for the left and right tubular portions 2 described above. The heat retaining member 3 is formed of a cloth piece having an appropriate shape such as a vertically long rectangular shape, and is attached in a state of being superimposed on the inner surface of the cylindrical portion 2 as shown in FIGS. Have been. Therefore, if this warm clothing 1 is worn, the thermal insulation member 3 cannot be seen from the outside.

The heat retaining member 3 is attached to the cylindrical portion 2 by sewing along the outer peripheral portion of the heat retaining member 3. The width direction (θ) occupied by the heat retaining member 3 with respect to the first half of the cylindrical portion 2 is exactly the one side edge of the front side joint portion with the gusset 4 provided at the crotch portion of the heat retaining garment 1.

【Example】

[Test 1] Heat insulation garment 1 of the present invention described in the first embodiment (see FIGS. 1 to 3) and conventional short pants without heat insulation member 3 (the shape is the same as that shown in FIG. 1) When,
A human physiology test was performed as described below using the conventional long pants under which the heat retaining member 3 was not provided (the shape was the same as that shown in FIG. 14).

The environmental conditions are as shown in FIG.
° C, humidity 50% R. H. After keeping the chair in a resting state (equilibrium period) for 60 minutes in an artificial climate room of room temperature, the room temperature was adjusted to 25 ° C. and the humidity was adjusted to 50% RH. H. The temperature was lowered at a constant rate over a period of 60 minutes with the target of, and after reaching the target, the environment was kept as it was for 30 minutes. These environmental conditions assume a climate between the outer garment and the underwear in autumn and winter.

Then, the rectal temperature is measured every 15 minutes for 120 minutes starting from the midpoint of the break-in time (after 30 minutes), and the peripheral skin is measured for 120 minutes every 5 minutes from the start time. The temperature was measured, and the blood pressure was measured every 15 minutes to examine the effect of lowering the room temperature. The subjects were three elderly people in their 60s and 1
Each person wore the heat retaining garment 1 of the present invention, the conventional lower trousers, and the conventional lower trousers. The common clothes of each subject were briefs, long-sleeved shirts, and socks (all 100% cotton).

The cloth and the heat insulating member 3 used as the base in the heat insulating garment 1 of the present invention and the cloth used under the conventional shorts are both cotton yarn 40th and the knitting is smooth (double-sided knitting).
It was assumed that. The fabric used under the conventional long pants was cotton yarn 30th and the knitting was performed by milling.

The socks used were made of cotton yarn 24th and knitted by rib knitting (rubber knitting). For measurement of rectal temperature, a thermistor high-precision temperature data recording device “K731” manufactured by Techno Seven Co., Ltd. was used. For measurement of blood pressure, a non-invasive continuous automatic blood pressure monitor “2300 Fin” manufactured by Omeda Corporation was used.
apres "was used.

For measuring the peripheral skin temperature, a high-precision temperature data recording device “K73” manufactured by Techno Seven Co., Ltd.
1 "was used. 30 to 32 are graphs showing the results of various measurements, and FIG. 33 summarizes the results of questionnaires by the test subjects. Reference materials 1 to 5 show the temperature distribution on the body surface at the time of various measurements using a thermography (thermal measurement imager): "Thermal Video System TVS-8100 (Sterling cooler type)" manufactured by Nippon Avionics Co., Ltd. It is a hard copy showing the result of the examination. In any of FIGS. 30 to 33, the heat insulation garment 1 of the present invention is represented by “B”, the lower part of the conventional shorts is represented by “A”, and the lower part of the conventional long pants is represented by “C”.

As a result of the measurement, as shown in FIGS. 30 and 31, both the rectal temperature and the peripheral skin temperature (finger and toe)
It shows a tendency to decrease as the room temperature decreases (from 30 minutes after the start of measurement). Among them, the rectal temperature did not show a large difference between the clothes, but the peripheral skin temperature showed that the warming garment 1 of the present invention was 0.2 ° C. less than other conventional garments.
It is clear from FIG. 1 that a good heat retention performance of 1 ° C. or more was exhibited.

This can also be seen from the reference materials 1 to 5, in the thermal insulation garment 1 of the present invention, the range from the shoulder to the chest and the upper arm, the range from the wrist to the back of the hand and the fingertip, the thigh, the ankle to the foot. This is obvious from the fact that it shows a broader and higher temperature distribution than other conventional garments in the range over the back and toes. That is, the warm clothing 1 of the present invention.
In this case, since the skin temperature was not significantly reduced even when the room temperature was lowered, the result was obtained that the burden on the heart due to vasoconstriction causing the skin temperature reduction, that is, the increase in blood pressure was also suppressed (see FIG. 32). .

[0064] While the subjects wearing the conventional short trousers and long trousers complained of a cool feeling as a result of the change in the environmental temperature, the subjects wearing the warm clothing 1 of the present invention showed a cold. The answer was that they hardly felt (see FIG. 33). This also supports the above various measurement results. [Test 2] The heat insulation garment 1 of the present invention described in the first embodiment (see FIGS. 1 to 3) and the conventional long pants without the heat insulation member 3 (the shape is the same as that shown in FIG. 14) , A heat retention performance test was performed as follows.

The environmental conditions are as shown in FIG.
° C, humidity 40% R. H. After keeping the chair in a resting state (equilibrium period) for 60 minutes in an artificial climate room at room temperature, a room temperature of 15 ° C. and a humidity of 40% R.C. H. The room temperature was lowered at a constant rate over a period of 90 minutes, with the subject being subject to intermittent ergometer exercise for the last 30 minutes. These environmental conditions are based on the environmental temperature in autumn and winter (the environment outside the sportswear). The chair resting state assumes indoors in daily life, and the intermittent ergometer exercise state assumes walking out. are doing.

In Test 2, in order to approach the actual clothing living conditions, the subject was worn on a jersey cloth-free sportswear upper and lower as a common clothing. Then, various data were collected at intervals as short as possible over a period of 90 minutes from the time when the break-in time elapses as the start time. The test subjects were five, and the test was conducted when each of the subjects wore the thermal insulation garment 1 of the present invention, when they wore the conventional long pants, and when they did not wear the corresponding clothing. .

The average age of the test subjects was 70.2 ± 4.7.
(Age), average height is 162 ± 7 (cm), average weight is 5
4.9 ± 7.5 (kg), average subcutaneous fat thickness is 9.6 ±
It was 4.0 (mm). Both the base fabric and the heat insulating member 3 in the heat insulating clothing 1 of the present invention are made of cotton yarn 40.
The knitting was done by smooth (both sides).

The fabric used under the conventional long pants is
The knitting was performed using a milling knit with a cotton yarn count of 30. The socks used were knitted with cotton yarn 24th and knitted by rib knitting (rubber knitting). The top and bottom of the sportswear were made of cotton yarn 40th and knitted smoothly (both sides).

For measuring the temperature in clothes, a high-precision temperature data recording device “K73” manufactured by Techno Seven Co., Ltd. was used.

For measurement of body temperature and skin temperature of each part, a thermistor high-precision temperature data recording device “K731” manufactured by Techno Seven Co., Ltd. was used. For measurement of blood pressure, a non-invasive continuous automatic blood pressure monitor “2300 FINAP” manufactured by Omeda Corporation was used.
res "was used.

FIGS. 35 to 47 are graphs showing the results of various measurements, and FIGS. 48 and 49 summarize the results of questionnaires by the subjects. Reference materials 6 to 8 indicate the temperature distribution on the back of the foot using thermography (thermal measurement imager): "Thermal Video System TVS-8100 (Sterling cooler type)" manufactured by Nippon Avionics Co., Ltd. at the time of various measurements. 3 is a hard copy showing the result of examining. In any of FIGS. 35 to 47, the heat insulation garment 1 of the present invention is represented by “H”, and the lower part of the conventional long pants is represented by “L”. “N” indicates a case where the undergarment corresponding to the area under the pants is not worn.

Considering the results of the measurement, first, FIG.
5 is a measurement result of the temperature in the clothes, from which a tendency of a decrease parallel to the room temperature is observed, and it is confirmed that the temperature gradient is peculiar to autumn and winter. It can be seen that there is little deviation. On the other hand, it has been clarified that the thermal insulation effect of the thighs has a large difference depending on the type and presence of clothing.

FIG. 36 shows the measurement results of the rectal temperature. In this case, too, the tendency of the decrease was observed in parallel with the room temperature.
It is confirmed that the temperature gradient is peculiar to winter, and at the same time, it can be seen that there is little deviation due to the type of clothing. On the other hand, FIG. 37 shows the transition of the average body temperature representing the calorie of the entire body, and FIG. 38 shows the transition of the average skin temperature obtained from the skin temperature measurement data of each part of the body shown in FIGS. 39 to 45, the lower leg skin temperature (FIG. 4)
4), the thermal insulation clothing 1 of the present invention
It can be seen that the decrease in skin temperature when wearing is suppressed.

It is to be noted that the reason why the warming effect of the lower leg skin temperature when wearing the conventional long pants is higher than that when the warm clothing 1 according to the present invention is worn is that the difference in the area surrounding the skin appears. It is presumed that only the lower part of the conventional pants covers the lower leg (heat insulation effect). However, when the warm clothing 1 of the present invention was worn, the skin temperature of the peripheral part (fingers, toes) was high, so that the blood circulation of the whole body was better than under long pants and when not wearing it.
Furthermore, it can be said that the exercise function is better as compared with the case where the conventional long pants are worn, and that it has a much more excellent heat retaining effect than the case where the underwear is not worn.

From the above, as a comprehensive evaluation based on FIGS. 37 and 38, when the thermal insulation garment 1 of the present invention is worn, compared with the case where the conventional long pants are worn or the case where the undergarment is not worn. It can be said that it shows good heat retention performance. Of course, these factors are due to the thermal insulation of the thigh by the thermal insulation member 3. As one consideration, since it is known that the thigh is more sensitive to the cold spot than the lower leg, the effect on the input of “warm” to the brain depends on the temperature of the thigh skin temperature by the heat retaining member 3 and the air layer. It can be said that heat retention is a major factor.
That is, by such an effective input to the brain, not only the trunk (see FIG. 39) and the upper limb (see FIG. 40) but also the peripheral parts, that is, the fingers (see FIG. 41) and the back of the foot (see FIG. 45)
Thus, it is considered that an instruction has been issued to suppress the contraction of cutaneous blood vessels.

Looking at Reference Materials 6 to 8, the degree of decrease in the skin temperature of the back of the foot was observed when wearing under conventional long trousers (Reference Material 8) and without wearing underwear underwear (Reference Material). 6)
In contrast, in the case where the heat is kept partially by the heat-retaining garment 1 of the present invention (reference material 7), it is remarkably suppressed, that is, it is obvious that the heat is kept. FIG. 46 and FIG. 47 show the results of measuring the pulse and the average blood pressure as indicators of the circulatory system. In FIG. 46, although there is little difference in the pulse due to the type and presence or absence of clothing, FIG. 47 shows that blood pressure shows a low value when the warm clothing 1 of the present invention is worn.

This is a result of a reduction in skin temperature caused by the contraction of blood vessels causing a decrease in skin temperature, that is, an increase in blood pressure, because the skin temperature decreases little when the warm clothing 1 of the present invention is worn. It can be guessed. And as is clear from the questionnaire results shown in FIG. 48 and FIG. 49, as an impression during the test by the test subject, the answer that when wearing the warm clothing 1 of the present invention, almost no cold was felt,
It supports various measurement results. According to each subject, in the thermal insulation clothing 1 of the present invention, there is no special negative image such as difficulty in wearing, difficulty in movement, a feeling of burden when worn, difficulty in taking off, and the like.
From any of these viewpoints, the impression that the heat retaining garment 1 of the present invention was superior was obtained. [Test 3] The conventional thermal pajamas without the heat retaining member 3 (upper / lower) (the shape is the same as that shown in FIG. 27) and the thermal insulation garment 1 of the present invention described in the eighteenth embodiment (see FIG. 27).
A and 1B, and three types of pajamas in which the heat insulating member 3 is also provided on the sleeve portion 19 of the heat insulating garment 1A, which is an additional material to the eighteenth embodiment (see the nineteenth embodiment shown in FIG. 28). Was used to examine the heat retention effect as follows.

The environmental conditions were as follows: room temperature 30 ° C., humidity 50% R.P.
H. In the artificial climate room (Room A) for 60 minutes in a resting state (equilibrium period), then room temperature 20 ° C, humidity 50%
R. H. Was moved to an artificial climate room (Room B), and changes in skin temperature over time were observed while the chair was at rest. The subject was 69 years old 1
A total of four elderly people, three aged 70 and three. In addition, each person wore a common general underwear (brief, shirt) and socks.

The test results were determined by examining the surface temperature distribution of the face, the back of the hand, and the feet using a thermography (thermometer). Reference 9 is a hard copy showing the results. In Reference Material 9, the state of wearing pajamas in the related art, the state of wearing pajamas of the eighteenth embodiment, and the state of wearing pajamas with the heat retaining member 3 of the sleeve added to the eighteenth embodiment are shown.

As is apparent from Reference 9, in the thermal insulation garment 1 (and) of the present invention, the range from the wrist to the back and toes and the range from the ankle to the back and toes are lower than those of the conventional pajamas. It is clear that the distribution is also broad and in a warming state.

[0080]

As is apparent from the above description, the warm clothing according to the present invention can surely keep warm without deteriorating comfort and movement.
