Description

  The present invention relates to a garment with a crotch, and more particularly to a garment with a crotch that can locally keep only a specific portion of a wearer's thigh.

  Some people, such as the cold winter season, can't sleep well after entering the bed if their toes are not warm, and wear socks and warm clothing at bedtime and warm their bodies in the bath before going to bed.

As heat insulation clothing for measures against cold, there are those described in Patent Documents 1 to 3 below. In particular, the thermal insulation garment described in Patent Document 1 keeps the front part of the thigh or the entire circumference of the thigh with high heat dissipation efficiency, and compensates for the body temperature adjustment reaction that decreases with aging, thereby reducing the body temperature. Is to prevent.

  By the way, according to the investigations of the present inventors, it is possible to fall asleep smoothly when the peripheral blood vessels such as the toes are dilated at bedtime, that is, when the toes are warm, It was found that sleep is deeper when the temperature of the trunk is kept low.

  From the results of this investigation, the present inventors, when wearing socks and the above-mentioned thermal insulation clothing at bedtime, prevent the body's physiological reaction, which is a physiological reaction of human beings, by these thermal insulation effects, resulting in deep sleep. The knowledge that sleep becomes shallow because the temperature of the trunk becomes higher than the temperature that can be obtained.

  This is to prevent a decrease in body temperature by keeping a part having high muscle mass, such as the thigh, and a high heat generation efficiency, in the conventional warm clothing, and heat radiation from the human body is suppressed. This is probably because of this.

  On the other hand, if you take a bath and warm your body before going to bed, the peripheral blood vessels such as the toes will be in a dilated state, so you can sleep smoothly. I couldn't sleep well enough because my toes got cold and woke up.

  Therefore, an object of the present invention is to provide a garment with a crotch that can keep the toes warm and can sufficiently prevent the heat retaining effect on the trunk from becoming excessive.

  The present invention is a garment with a crotch comprising a heat retaining portion formed of a material having a heat retaining property and a body portion formed of a material having a heat retaining property lower than the heat retaining portion, wherein the heat retaining portion is a wearer It is formed in the position which covers at least one part of the site | part enclosed by this inguinal ligament, the long adductor muscle, and the sewing muscle.

  The present inventors locally maintain a region surrounded by the inguinal ligament, the long adductor muscle and the sewing muscle called the Scarpa Triangle (hereinafter referred to as “Scarpa Triangle”), so that the wearer's toes It was found that it can be kept warm.

  According to the garment with a crotch of the present invention, the wearer's scalpa triangle can be kept warm locally, so that the toes can be kept warm, while the warming effect on the trunk becomes excessive. Can be sufficiently prevented.

  FIG. 1 shows the position of the scarpa triangle. FIG. 1 is a front view showing muscles and skeletons when the lower limbs of a human body are viewed from the front side. As shown in FIG. 1, a portion surrounded by the inguinal ligament 101, the long adductor muscle 102 and the sewing muscle 103 is a scalloped triangle 100. The inguinal ligament 101 is the lower edge of the external celiac muscle aponeurosis, starting from the superior anterior iliac spine 111 and reaching the pubic bone connection 112.

  The scalloped triangle is a part located at the upper part of the thigh, and the femoral artery and the femoral vein flow near the skin surface on the upper inner side of the thigh, which is in the vicinity of the scalloped triangle. Since the femoral artery and the femoral vein are covered with a small amount of fat and muscle, heat is escaped from the blood passing through the femoral artery and the feet, and the feet cool down when the Scalpa triangle is not kept warm.

  According to the garment with a crotch of the present invention, the Scalpa triangle can be kept warm locally, and heat radiation from blood flowing through the femoral artery and the femoral vein located at this site can be suppressed, so that the toes can be kept warm. Moreover, since the site | part to heat-retain is local, the excess heat | fever of a trunk can be thermally radiated from another site | part, and it can prevent that the heat retention effect with respect to a trunk becomes excessive. As a result, the human body temperature regulation reaction is sufficiently prevented from being disturbed, and the temperature of the trunk is naturally adjusted to an appropriate temperature at which deep sleep can be obtained. The “trunk” refers to a part of the human body excluding limbs (upper limbs and lower limbs).

  Moreover, the garment with a crotch of this invention can be made into what is called a short type and a type with short length. That is, the garment with a crotch of the present invention is a garment with a crotch provided with a heat retaining portion formed of a material having heat retaining properties and a main body portion formed of a material having heat retaining properties lower than the heat retaining portion, The hem of the garment with the crotch is formed along the circumferential direction of the thigh from the root of the wearer's thigh, and the heat retaining part is provided on the wearer's inguinal ligament, long adductor and sewing muscle. It is characterized by being formed at a position covering at least a part of the enclosed part.

  Moreover, the garment with a crotch of the present invention can be a so-called semi-long type that is longer than the short type. That is, the garment with a crotch of the present invention is a garment with a crotch provided with a heat retaining portion formed of a material having heat retaining properties and a main body portion formed of a material having heat retaining properties lower than the heat retaining portion, The hem of the garment with the crotch is formed along the circumferential direction of the thigh in the thigh between the root of the wearer's thigh and the knee joint. It is characterized in that it is formed at a position that covers at least a part of the long adductor and a part surrounded by the inguinal ligament, the long adductor and the sewing muscle.

  In this invention, it is preferable that a heat retention part is comprised by sewing the cloth material which has heat retention with a main-body part. When the heat retaining part is fixed to the main body part, the position of the heat retaining part is prevented from being displaced when worn, and the Scalpa triangle can be stably kept warm. In addition, if this fixing is performed by stitching, the entire body can be made thinner compared to the case where the heat retaining portion is overlapped with the main body portion and stitched or bonded, and a feeling of wrinkling at the time of wearing can be prevented.

  According to the present invention, it is possible to provide a crotch garment that can keep the toes warm and can sufficiently prevent the heat-retaining effect on the trunk from becoming excessive.

  A detailed configuration and function of the crotch garment according to the present invention will be described using an embodiment of a short-type sleeping bottom. In the description of the drawings, the same reference numerals are given to the same elements, and duplicate descriptions are omitted.

  The aim and concept of the sleeping bottom according to the present embodiment are as follows. For example, when trying to go to sleep in a room with low temperature such as in winter, the toes get cold and sleep falls. On the other hand, when sleeping while wearing socks, heat-insulating clothing, etc., excessive heat in the body is not released during sleep, so that the trunk feels excessively warm and tends to sleep well. The “aim” of this embodiment is to prevent such “bad sleep” and “being unable to sleep soundly” and satisfy the needs of the wearer who wants to sleep smoothly and sleep well. By the way. And the concept is to keep the toes warm by locally warming the wearer's Scarpa triangle, and effectively releasing excess heat from the trunk by localizing the warmth. Keeping the temperature of the trunk at a temperature suitable for sleep.

  With reference to FIG. 2, the configuration and function of the short-type sleeping bottom for women according to the present embodiment will be described in detail. (A) of FIG. 2 is the figure which looked at the bottom for sleep from the front, (b) is the figure which looked at the bottom for sleep from the back.

  The sleeping bottom 10 shown in FIG. 2 fits the wearer's human body (bottom portion), and the body cloth material (main body portion) 1 mainly constituting the sleeping bottom 10 and one on each of the left and right sides. And a heat insulating cloth material (heat insulating portion) 2 provided one by one. Since the sleeping bottom 10 is a short type as shown in FIG. 2, the portions covered by the sleeping bottom 10 when worn are the middle abdomen, the lower abdomen, the buttocks, and the upper thigh. Note that the bottom of the sleeping bottom 10 is formed from the root 105 of the wearer's thigh along the circumferential direction of the thigh.

  The heat insulating cloth material 2 is made of a cloth material having a heat insulating property higher than that of the main body cloth material 1 and is formed at a position covering the upper part of the wearer's scalpa triangle. Specifically, the heat insulating cloth material 2 is formed at the following locations with respect to the sleeping bottom 10. That is, when worn, one side (hereinafter referred to as “inguinal groove line”) 11 extending from the root portion 105 of the thigh to the vicinity of the superior anterior iliac spine along the inguinal groove, and the root portion of the thigh One side (hereinafter referred to as “thigh circumferential direction line”) 12 extending from 105 to the frontal position of the thigh along the circumferential direction of the thigh, an inguinal groove line, and a thigh circumferential direction line This is a substantially triangular portion composed of one side (hereinafter referred to as “sewing line”) 13 connecting the end points.

  According to the sleeping bottom 10, since the Scalpa triangle is locally kept warm and heat radiation from the blood flowing through the femoral artery and the femoral vein located in this region can be suppressed, the toes can be kept warm. Moreover, since the site | part to heat-retain is local, the excess heat | fever of a trunk can be thermally radiated from another site | part, and it can prevent that the heat retention effect with respect to a trunk becomes excessive.

  In addition, when the sleeping bottom 10 is worn, since the inguinal groove line 11 of the heat insulating cloth material 2 is along the inguinal groove, the heat insulating cloth material 2 is bent even if the thigh is moved around the hip joint during sleep. It is sufficiently prevented that the region to be heated or the region to be kept warm is shifted, so that the Scalpa triangle can be kept warm stably.

  It is preferable that the size and the formation position of the heat insulation cloth material 2 are as follows in order to keep the wearer's scalpa triangle sufficiently warm. That is, the distance from the root of the thigh to the end point of each line is preferably 7 to 16 cm for the inguinal groove line 11 and 4 to 12 cm for the thigh circumferential direction line 12.

  The material used for the heat insulating cloth material 2 is not particularly limited as long as it has sufficient heat insulating properties. Examples of materials that can be suitably used for the heat insulating cloth material 2 include wool, acrylic brushed cloth, and moisture-absorbing exothermic fibers. Can be mentioned. Among these, a hygroscopic exothermic fiber excellent in elasticity is preferable from the viewpoint of achieving both heat retention and excellent fit. Examples of such hygroscopic exothermic fibers include ex (trade name) and well thermo (trade name). Is mentioned.

  The heat retention rate of the heat insulating cloth material 2 is preferably 28 to 50%, and more preferably 32 to 47%. If the thermal insulation rate of the thermal insulation fabric material 2 is less than 28%, the thermal insulation effect of the thermal insulation fabric material 2 tends to be insufficient, and if it exceeds 50%, the thermal insulation portion is overheated due to an excessive thermal insulation effect and feels uncomfortable. Tend. In addition, the ratio of the heat retention rate of the heat insulation fabric 2 to the value of the heat retention rate of the main body cloth material 1 is preferably 1.35 or more, and if this ratio is less than 1.35, the scalloper triangle is localized. There is a tendency that the effect of keeping warm is not sufficiently obtained.

In addition, a heat retention rate [%] can be calculated | required as follows using a heat retention tester. That is, the constant temperature heat source body is covered with a sample cloth, adjusted so that the temperature of the constant temperature heat source body is 30 ° C., the amount of heat radiated from the heat source body toward the low temperature outside air (20 ° C.) becomes constant, and the heat source body The amount of heat radiation W [J / cm ² · s] from the heat source body after 10 minutes has elapsed after the surface temperature of the steel sheet shows a constant value. On the other hand, the heat radiation amount W ₀ [J / cm ² · s] from the heat source body is measured in the same manner as described above without covering the heat source body with the sample fabric. By substituting these values into the following formula (1), the heat retention rate of the sample fabric is obtained. As the heat retention tester, for example, “KES-F7 Thermolab 2” manufactured by Kato Tech Co., Ltd. can be used.
Thermal insulation rate [%] = (1−W / W ₀ ) × 100 (1)

  The material used for the main body cloth material 1 that mainly constitutes the sleeping bottom 10 is not particularly limited as long as it has lower heat retention than the heat insulating cloth material 2, but as a material that can be suitably used for the main body cloth material 1, Cotton, nylon, rayon, silk, wool and the like. Among these, natural materials such as cotton are preferable from the viewpoint of preventing a feeling of tightening during wearing and a feeling of wearing during sleep. In addition, from the viewpoint of preventing a feeling of stiffness when worn, a thin fabric is suitable for the main body fabric material 1.

  16-35% is preferable and the heat retention of the main body cloth material 1 is more preferably 20-28%. When the heat retention rate of the main body cloth material 1 is less than 16%, the heat insulating effect of the portion covered with the main body cloth material 1 tends to be insufficient. On the other hand, if it exceeds 35%, the wearer may feel that the portion covered with the main body cloth material 1 is too hot. In addition, what is necessary is just to obtain | require the heat retention rate of the main body cloth material 1 similarly to the heat insulation cloth material 2. FIG.

  The sleeping bottom 10 is designed to have a size that does not tighten the upper abdomen, lower abdomen, buttocks and thighs of the wearer. For this reason, a soft wearing comfort is obtained, and it is possible to sufficiently prevent a feeling of tightening that is uncomfortable even when sleeping while wearing this. In addition, it is preferable to use the cloth material which has sufficient elasticity as the main body cloth material 1 and the heat insulation cloth material 2 which comprise the bottom 10 for sleep from a viewpoint that an abdominal part, a buttocks, and a thigh are not tightened.

  Next, a method for manufacturing the sleeping bottom 10 will be described with reference to FIG. FIG. 3 is a diagram for explaining a manufacturing process of the sleeping bottom 10. As shown in FIG. 2A, a main body cloth material 1 and a heat insulating cloth material 2 cut into predetermined dimensions are prepared, and the main body cloth material 1 and the heat insulating cloth material 2 are stitched together, as shown in FIG. And the stitched portion 5 formed by the edges of the main body cloth material 1 and the heat insulating cloth material 2 is abutted and stitched together. FIG. 5C is a view of the sleeping bottom 10 after the suture portion 5 is sutured, as observed from the front side.

  The means for fixing the heat insulating cloth material 2 to the main body cloth material 1 includes knitting, sewing, adhering and adhering in addition to the sewing, but if the fixing is by sewing, it is for sleeping. The entire bottom 10 can be made thin, and a feeling of stiffness when worn can be prevented.

  Although the short type sleeping bottom has been described in the above embodiment, the crotch garment of the present invention is not limited to the short type and may be a semi-long type.

  With reference to FIG. 4, the structure and function of the semi-long type sleeping bottom for women according to another embodiment will be described in detail. 4A is a view of a semi-long type sleeping bottom as viewed from the front, and FIG. 4B is a view of a semi-long type of sleeping bottom as viewed from the back.

  The configuration of the sleeping bottom 20 shown in FIG. 4 is the same as that of the sleeping bottom 10 except that the size and length of the heat insulating cloth are different, and can be sewn in the same manner as the sleeping bottom 10. The bottom of the sleeping bottom 20 is formed along the circumferential direction of the thigh in the thigh between the root 105 of the thigh of the wearer and the knee joint 106.

  The heat insulating cloth material 22 provided in the sleeping bottom 20 includes the heat insulating cloth material 2 and the heat insulating cloth material 2a. The heat insulation cloth material 2 can use the same thing as the heat insulation cloth material 2 in the sleeping bottom 10. On the other hand, the heat insulating cloth material 2 a is formed in the length direction of the thigh from the thigh circumferential direction line 12 of the heat insulating cloth material 2, is made of the same material as the heat insulating cloth material 2, and is integrated with the heat insulating cloth material 2. It has become. Specifically, as shown in FIG. 4, the heat insulating cloth material 2 a is along the thigh circumferential direction line 12 and the thigh thigh length direction from the thigh root to the thigh thigh length direction as shown in FIG. 4. It is formed in a portion surrounded by one side (hereinafter referred to as “thigh length direction line”) 14 extending to the position of the hem, a line 13 a extending the sewing muscle line, and a line 15 in the circumferential direction of the hem. ing.

  According to the sleeping bottom 20, the Scalpa triangle and the long adductor muscle are locally kept warm, and heat radiation from the blood flowing through the femoral artery and the femoral vein located in this region can be sufficiently suppressed, so that the feet are warm. Can be maintained. Moreover, since the site | part to heat-retain is local, the excess heat | fever in a body can be thermally radiated from another site | part, and it can prevent that the heat retention effect with respect to a trunk becomes excessive.

  The sleeping bottom 20 is a semi-long type, and has a length longer than that of the sleeping bottom 10, and is suitable for a person whose feet are likely to get colder or a person who uses at a lower temperature. In the sleeping bottom 20, the area of the heat insulating cloth material can be made larger than that of the sleeping bottom 10, and the heat retaining portion extends to the long adductor muscle in addition to the Scarpa triangle, and the femoral artery and the femoral vein are This is because heat radiation from the flowing blood can be more sufficiently suppressed.

  Further, when the sleeping bottom 20 is worn, since the inguinal groove line of the heat insulating cloth material 22 is along the inguinal groove, the heat insulating cloth material 22 is bent even if the thigh is moved around the hip joint during sleep. In addition, since it is sufficiently prevented that the part to be kept warm is shifted, the Scalpa triangle can be kept warm stably.

  In addition, the shape of the heat insulation cloth material 2a does not necessarily need to be a substantially square shape, and the shape may be selected according to the length of the sleeping bottom as shown in FIG. For example, when the length is longer than (c) shown in FIG. 5, the shape of the heat insulating cloth 2a is substantially triangular. The range kept warm by the heat insulating cloth material 2a and the heat insulating cloth material 2 in this case is defined as the maximum heat insulating range. If the thigh is kept warm over a range wider than this range, excess heat from the trunk will not be released efficiently, and some wearers may feel hot. In this case, the size of the heat insulating cloth material 2a depends on the size of the sleeping bottom to be manufactured, but the length of the thigh length direction line 14 is 16 to 24 cm.

  In FIG. 5, the length having the length (a) is the short sleeping bottom 10, and the length having the length (b) is the semi-long sleeping bottom 20. .

  So far, the sleep bottom for women has been described, but the crotch garment of the present invention is not limited to women, and may be manufactured by sewing for men.

  Moreover, the clothing with a crotch of the present invention is not limited to the one to be worn at the time of sleeping, and may be one to be worn during the day other than at the time of sleeping. According to the garment with a crotch of the present invention, since the heat retaining effect on the trunk does not become excessive, while the feet can be kept warm, for example, for a person whose feet are cooled by cooling in an office or the like in the summer time. It is very suitable.

  The bottoms for sleep of the following examples and comparative examples were produced, and the ease of falling asleep was evaluated for each.

<Example 1>
A short type sleeping bottom similar to that shown in FIG. 2 was manufactured as follows. That is, Turfan cotton (trade name) (heat retention rate: 20%) was used as the main body fabric material, and acrylic brushed fabric (heat retention rate: 33%) was used as the heat insulation fabric material. The main body cloth material and the heat insulation cloth material were cut into predetermined dimensions, and the respective cloth materials were sewn to sew the sleeping bottom. In addition, the shape of the heat insulating cloth material was substantially triangular, and the dimensions were such that the length of the inguinal groove line was 14 cm, the length of the thigh circumferential direction line was 9 cm, and the length of the sewing muscle line was 9 cm.

<Comparative Example 1>
A short-type sleeping bottom was produced in the same manner as in Example 1 except that the whole was produced using Turfan cotton (trade name) (heat retention rate: 20%).

<Example 2>
The length of the length and the dimensions of the heat insulation cloth were changed, and a standard type sleeping bottom was manufactured. The shape of the heat insulating cloth material was substantially rectangular, and the dimensions were such that the length of the inguinal groove line was 14 cm, the length of the thigh length direction line was 10 cm, and the length of the sewing muscle line was 31 cm. The length was 10 cm. The cloth used as the main body cloth material and the heat insulation cloth material was the same as that in Example 1.

<Comparative example 2>
Standard type sleep in the same manner as in Example 2 except that the whole was manufactured using Outlast (trade name) (heat retention: 28%, material: acrylic 90%, nylon 5%, polyurethane 5%). A bottom was manufactured.

  Two subjects were allowed to wear the sleeping bottom of Example 1 to evaluate the ease of falling asleep. FIG. 6 shows changes over time in the degree of variation in heart rate from entering the subject. The degree of heartbeat variability was quantified as follows. That is, the degree of variation in heart rate is the relationship between the sleep depth and the Lorentz plot in the sleep transition period, and the distance from the origin on the y = x axis of the Lorentz plot (hereinafter referred to as “center of gravity”) as the sleep depth increases. Based on the knowledge that the change gradually became stable and leveled, the PRI during sleep was measured using a simple heartbeat measuring device Active Tracer AC301 (trade name, manufactured by GMS Co., Ltd.). Then, using this measured value, the degree of variation in the center of gravity for 60 minutes after entering the floor is calculated every minute, and the average value after 0 to 20 minutes, 21 to 40 minutes, and 41 to 60 minutes is obtained to obtain a numerical value. Turned into.

  FIG. 6 also shows the results of having two subjects wear the sleeping bottom of Comparative Example 1 and evaluating the ease of falling asleep in the same manner. It shows that it is easy to fall asleep, so that the dispersion | variation degree of a heart rate is small (a numerical value is small), and when the bottom for sleep of Example 1 is worn, the dispersion | variation in a heart rate is compared with the case where the bottom for sleep of Comparative Example 1 is worn. It was confirmed that the degree was small and it was easy to fall asleep smoothly.

  As a result of evaluating the ease of falling asleep similarly to Example 2 and Comparative Example 2 as described above, when the sleep bottom of Example 2 was worn, when the sleep bottom of Comparative Example 2 was worn It was confirmed that the degree of variability in heart rate was smaller than that, and it was easy to fall asleep smoothly.

<Example 3>
Implemented with the exception of using well thermo (product name) (heat retention rate: 47%) as the thermal insulation material, and also using well thermo (product name) (thermal insulation rate: 34%) as the main fabric material. A standard type sleeping bottom was produced in the same manner as in Example 2.

<Comparative Example 3>
Welther (trade name) (thermal insulation rate: 47%) is used as the heat insulation material, and the heat insulation material is sutured so as to cover not only the thigh scalpa triangle but also the entire circumferential direction of the upper thigh. Produced a semi-long type sleeping bottom. The length was 8 cm. In addition, well thermo (trade name) (heat retention: 47%) was used as the main body cloth material.

<Evaluation of the sense of warmth>
Sensory evaluation on warmth was performed as follows. That is, five test subjects were allowed to wear the sleeping bottom of Example 3 and were put in a futon under the conditions of a temperature of 13 ° C. and a humidity of 50%. Further, the sleeping bottom of Comparative Example 3 was worn instead of the sleeping bottom of Example 3 and was put into a futon in the same manner.

About sleep of Example 3 and Comparative Example 3 about "feeling of warmth of the toes", "feeling of warmth of the lower body", and "feeling of warmth of the trunk" 7 minutes after entering the futon We asked if they felt warmth when wearing the bottom. Table 1 shows the number of people who answered “I felt warmer” for one of the five sleeping bottoms.

  In the sensory evaluation regarding warmth, none of the subjects answered that the sleep bottom of Example 3 felt warmer than the sleep bottom of Comparative Example 3 in all items. However, as a result of hearing opinions on each item, the following responses were received.

  As for “feeling of warmth of the toes”, there was a reply that “in Example 3, it takes more time to feel the toes warmer than in Comparative Example 3”. In addition, the answer of “warmly warm” was conspicuous when the sleeping bottom of Example 3 was worn.

  Regarding the “feeling of warmth of the lower body”, when wearing the sleep bottom of Comparative Example 3, the answer “very warm overall” was conspicuous. On the other hand, when the sleep bottom of Example 3 was worn, the answer that “it is not cold but takes time to feel warm” was conspicuous.

  Regarding the “feeling of warmth of the trunk”, while the sleep bottom of Comparative Example 3 was worn, there was an answer of “it was too hot” while there was an answer of “too hot”. On the other hand, the answer of “feeling moderately warm” was conspicuous when the sleeping bottom of Example 3 was worn.

  As a result, for the feeling of warmth of the toes and lower body, when the sleeping bottom of Example 3 is worn, it takes time to feel warmth compared to the sleeping bottom of Comparative Example 3, It was also confirmed that the lower body was fully warm.

  On the other hand, about the warmth of the trunk, when the sleep bottom of Example 3 was worn, the subject felt moderate warmth. On the other hand, when wearing the sleep bottom of Comparative Example 3, some subjects felt that it was too hot.

<Evaluation of sustainability of the warmth of the toes>
The bottom surface for sleep of Example 2 was worn, and the skin surface temperature below the knee of the subject who was allowed to rest for 20 minutes in an environment of a temperature of 23 ° C. and a humidity of 50% was observed by thermography. Furthermore, after the sleep bottom of Comparative Example 3 was worn instead of the sleep bottom of Example 2 and allowed to rest under the same conditions, the skin surface temperature was similarly observed by thermography.

  As a result, even when the sleeping bottom of Example 2 was worn, it was confirmed that the feet were sufficiently warm in the same manner as when the sleeping bottom of Comparative Example 3 was worn. .
