Description

  The present invention relates to a lower garment.

  Up to now, for people who have no problem with physical ability and activity level, or for people with relatively high physical ability and activity level, clothes such as sportswear and sports inners, wearer movement support functions, and fatigue reduction functions Various garments equipped with have been proposed. For example, a garment that maintains or enhances daily physical activity, or a garment that supports knee joint movement and can reduce fatigue of the wearer, such as stretching the knee joint in a bent state. Underwear to support is known. In the lower garment, the stretch resistance in the height direction of the wearer is larger than the stretch resistance in the direction perpendicular to the height direction. Specifically, the high stretch resistance portion in which the stretch resistance in the height direction of the wearer is larger than the stretch resistance in the direction perpendicular to the height direction is disposed on the front side of the lower garment. And it is the structure each latched by the latching part in the thigh side and the lower leg part with respect to the patella. And by the structure of such clothes, when standing up from a chair or the like, using the resistance force of the high stretch resistance part of the wearer's leg part, it is easy to get up and bring about the effect of reducing muscle strain Yes (see Patent Document 1).

JP 2007-303040 A

  The innerwear shown in the above-mentioned Patent Document 1 is intended for people who have no problem in physical ability and activity level, or who have relatively low physical ability and activity level. It only proposes a new shape. On the other hand, people with relatively low physical abilities and activity levels tend to have leg muscles that become thinner and thinner, and the abdomen tends to have fat and the like, and the abdominal circumference tends to increase with lack of exercise and aging. When the conventional general lower garment is worn, the upper end comes to a position where the abdominal circumference becomes the maximum or a position below it. Therefore, when a person with relatively low physical ability or activity, for example, an elderly person or an obese body person, especially a person with an extremely large abdominal circumference with respect to the circumference of the leg, wears the lower garment, There is a problem that the lower garment tends to be displaced downward. Furthermore, since the innerwear shown in Patent Document 1 assists the rising motion using the resistance of the high stretch resistance portion of the wearer's leg, the physical tension of the fabric is in the height direction. It has a structure that works downward and helps the innerwear shift downward. Therefore, according to the present invention, the upper end of the lower garment slides down in the height direction during walking motion even for a person whose abdominal circumference is extremely large with respect to the circumference of the leg and whose physical ability and activity are relatively low. It is an object of the present invention to provide a lower garment for causing the lower garment to have a support function that facilitates joint movements by the wearer's own muscular strength as intended.

The present invention has the following configuration. That is,
(1) A lower garment having a lower garment main body and means for applying tension to a wearer substantially in a height direction on at least a part of the lower garment main body, The ratio of the upper end width of the lower garment body to the upper end width (crotch length / upper end width) is 0.9 to 1.5, and the elongation at break in the height direction of the wearer of the lower garment body is 150%. ~ 300% underwear,
(2) When the lower garment is worn, the means for applying tension to at least a part of the lower garment main body in the direction of the height of the wearer is below the portion of the lower garment body covering the iliac crest of the wearer. The garment body is disposed on the garment body so as to cover a portion of the garment body that covers the front of the thigh of the garment body and a portion of the garment body that covers the inner part of the patella of the wearer. One end of the means for applying tension to the wearer's substantially height direction with respect to at least a part of the wearer is fixed to a portion of the lower garment body covering the iliac crest of the wearer, and at least one of the lower garment body The lower garment according to (1), wherein the other end of the means for applying tension to the wearer substantially in the height direction of the wearer is fixed to a portion of the lower garment body that covers the inner side of the patella of the wearer,
(3) The coefficient of static friction between the lower garment main body and the lower garment main body and a portion not fixed to the lower garment main body for applying tension to at least a part of the lower garment main body in the height direction of the wearer is 0.3. It is the undergarment as described in said (1) or (2) which is -0.7.

  According to the present invention, the upper end of the lower garment slides down in the height direction during walking even for a person whose abdominal circumference is extremely large relative to the circumference of the leg and whose physical ability and activity are relatively low. Therefore, it is possible to provide a lower garment in which the support function of the lower garment, which makes the joint movement by the wearer's own muscular strength easy, can work as intended.

FIG. 1 is a schematic front view when a lower garment is worn according to an embodiment of the present invention. FIG. 2 is a schematic front view of a band used in an embodiment of the lower garment of the present invention. FIG. 3 is a schematic front view of a garment body according to an embodiment used in the garment of the present invention shown in FIG. 1. FIG. 4 is a schematic right side view of the lower garment body according to an embodiment used in the lower garment of the present invention shown in FIG. 1. FIG. 5: is a schematic side view when a wearer wears the lower garment main body which concerns on another embodiment of the lower garment of this invention. FIG. 6: is a schematic side view when a wearer wears the short garment main body which has a short rise like a conventional garment.

  Hereinafter, embodiments of the present invention will be described in detail. The lower garment of this invention has a lower garment main body and a means to give tension | tensile_strength to a wearer's substantially height direction with respect to at least one part of the said lower garment main body.

  And the ratio (rising length / upper end width) of the placing dimension crotch length of the said garment main body and the placing dimension upper end width of the said garment main body is 0.9-1.5. Here, as shown by 6 in FIG. 3 (a), the placement length of the lower garment body means the length of a perpendicular extending from the gusset portion of the crotch to the upper end of the lower garment body. The placement dimension upper end width of the garment body refers to the width of the upper end of the lower garment body, as indicated by 7 in FIG. Here, the lower limit value of the ratio of the placing dimension crotch length of the lower garment body and the placing dimension upper end width of the lower garment body (rise length / upper end width) is the abdomen where the waist circumference of the garment wearer is maximized. In order to cover completely, it is 0.9 or more, and preferably 1.0 or more. On the other hand, the upper limit of the ratio between the crotch length of the lower garment body and the upper end width of the lower garment body (the crotch length / the upper end width) is the workability of the wearer and the adhesion of the lower garment to the body. In order to maintain the properties, it is 1.5 or less, and preferably 1.1 or less.

  Here, people with relatively low physical ability and activity (for example, elderly people) tend to have an extremely large abdominal circumference with respect to the circumference of the leg, and such physical ability and activity are relatively When a low-priced person wears a conventional lower garment that matches the shape of people with relatively high physical abilities and activities, as shown in FIG. The upper end of the conventional garment will be arranged below the part to be. Further, the lower garment of the present invention has means for applying tension to the wearer's substantially height direction to at least a part of the lower garment body (hereinafter sometimes referred to as tension applying means). It is structured to assist the movement of the wearer's hip joint during walking using the tension of the means. Therefore, physical tension in the wearer's approximate height direction is applied to at least a part of the lower garment by the means, and the lower garment is likely to slide down further in the approximate height direction of the wearer. Therefore, if the lower garment has the same shape as the conventional lower garment as shown in FIG. 6, the leg part has a shape that is extremely narrower than the abdomen. Accordingly, the upper end portion of the conventional lower garment easily shifts downward. However, as in the present invention, a garment having a ratio of the crotch length of the lower garment main body to the upper end width of the lower garment main body (crotch length / upper end width) of 0.9 to 1.5 is worn. Then, the upper end of the lower garment comes above the position where the wearer's abdominal circumference becomes the maximum, and as shown in FIG. 5, the abdominal circumference is extremely large with respect to the circumference of the leg, and the physical ability Even when the activity level is relatively low, the upper end of the lower garment and the abdomen where the wearer's abdominal circumference is maximized exert an anchor effect during walking movement, and it is suppressed that the lower part slides down in the height direction. . That is, as in the present invention, it has means for applying tension to the wearer's substantially height direction with respect to at least a part of the lower garment body. Even if it is in a state of being easily slipped down, the upper garment of the lower garment comes above the abdomen where the abdominal circumference is maximum, that is, the wearer's abdominal circumference is maximized. The increase in body circumference from the upper part of the abdomen toward the abdomen where the wearer's abdominal circumference is maximized functions as a stopper for the downward movement of the upper end of the lower garment to suppress the lowering of the lower garment Can do.

  Here, the fabric used for the lower garment body is a stretchable fabric having elasticity, and the elongation at break in the substantial height direction of the fabric used for the lower garment body needs to be 150% to 300%. . Here, the lower limit of the elongation at break in the substantial height direction of the fabric used for the lower garment body is 150% or more and 250% or more in order to improve the adhesion of the lower garment to the body. Preferably there is. On the other hand, the upper limit of the breaking elongation in the substantial height direction of the cloth used for the lower garment body is that the shape of the lower garment collapses and the tension of the tension applying means cannot be transmitted well to the body, and induces desirable joint movement. In order to prevent becoming difficult, it is 300% or less. The lower garment of the present invention is to be worn on the lower limbs, and the main movements of the lower limbs include bending / extending movements of the knee joint and the hip joint. When such an operation is performed, if the fabric is not stretchable, the fabric will be stretched at the portion covering each joint, which will hinder the operation. Therefore, the stretchability of the fabric in the direction that is particularly stretched during operation, that is, the height direction of the wearer is required.

  The stretchable fabric used for the lower garment body is preferably made of polyurethane elastic fiber. Among them, polyurethane elastic fiber is a commercially available lycra (registered trademark) such as T-127C (trade name) or T-906C (product). Name) or the like. Here, the stretchable fabric may be either a woven fabric or a knitted fabric, but a knitted fabric is more preferable in that it has high stretchability and can impart sweat absorption and quick drying functions depending on the tissue structure. The knitting structure may be either a warp knitting or a weft knitting, but more preferably a warp knitting capable of obtaining a higher tension in order to improve the adhesion of the fabric, and may be a mesh shape.

  Moreover, the lower garment body may be made of one type of fabric or two or more types of fabrics. In particular, the upper peripheral portion of the lower garment body covers up to the upper part of the abdomen where the wearer's abdominal circumference is maximized, so there is a possibility that the tightening may be tight and tight. In such a case, it is possible to make only the upper peripheral part of the lower garment body a fabric that is weakly tightened. Further, as indicated by 5 in FIG. 3 (a), a guide line may be provided in advance at the portion where the tension applying means is disposed by a stitch or the like.

  The lower garment body is not particularly limited as long as it has a shape covering at least the wearer's iliac crest at the wearer's iliac crest and the lower left and right knees. It may be covered. As shown in FIG. 4, the ease of wearing is further improved by providing a fastener at the hem. Further, a waist elastic band may be sewn to the upper end of the lower garment to enhance the anchor effect.

  Moreover, the undergarment of this invention has a tension | tensile_strength provision means as mentioned above. Here, the tension applying means passes through a portion covering the thigh front of the wearer of the lower garment body from a portion covering the iliac crest of the wearer of the lower garment main body, and an inner part of the patella of the wearer of the lower garment body It is preferable that it is arrange | positioned at the lower garment main body so that the part which covers may be covered. Further, one end of the tension applying means is fixed to a portion covering the iliac crest of the wearer of the lower garment body, and the other end of the tension applying means is an inner portion of the patella of the wearer of the lower garment body It is preferable that it is fixed to the portion covering. Thus, by arranging the tension applying means, it is possible to pull the wearer's hip joint in the height direction, and to exhibit a function of further appropriately assisting the bending motion of the hip joint.

  Here, it is preferable that the elongation stress of the cloth used for the tension applying means as described above is 2.0 to 5.5 N. The lower limit value of the elongation stress of the fabric used for the tension applying means is that the force that the tension applying means tries to return to the original shape is sufficiently exerted, and the movement of the joint can be appropriately induced in a desired direction. Therefore, it is preferably 2.0N or more. On the other hand, the upper limit value of the elongation stress of the fabric used for the tension applying means is preferably 5.5 N or less in order to further reduce fatigue due to maintenance of posture and body position of the wearer before induction of joint motion. . By using a fabric having an elongation stress in such a range as the tension applying means, the force with which the two ends attract each other becomes appropriate, and the wearability of the lower garment is further improved.

  Here, in the present invention, what is used as the tension applying means may be a partially changed knitted structure of the lower garment body, a fabric with different tensions attached, or one that is overlapped and sewn. Further, other means may be used. Furthermore, a plurality of tension applying means may be provided in the lower garment, and these tension applying means may be arranged on the lower garment main body at different positions or may be superposed.

  The tension applying means is not particularly limited as long as it includes a stretchable material such as natural rubber, plastic, metal (processed into a spring shape) and has appropriate elasticity. However, since it is used for a garment worn by a person, from the viewpoint of ensuring safety even if it falls down, the tension applying means is made of an elastic material such as rubber or resin or a stretchable fiber material. It is desirable that

  The fiber material that can be suitably used for the tension applying means is at least one selected from the group consisting of natural fibers such as silk and wool, regenerated fibers such as rayon, and synthetic fibers such as acrylic fibers and polyester fibers. Examples thereof include elastic knitted fabrics knitted with a mixture of seed fibers and elastic fibers (such as polyurethane elastic fibers and / or polyester elastomer fibers), and elastic woven fabrics knitted with elastic fibers alone.

  The composition of the fiber material may be a woven fabric or a knitted fabric, but a knitted fabric is more preferable in that it has high stretchability and can impart sweat absorption and quick drying functions depending on the structure of the fabric. The knitting structure may be either a warp knitting or a weft knitting, but more preferably a warp knitting capable of obtaining a higher tension.

  Here, although there is no restriction on the method of fixing the tension applying means to the lower garment body, in order to efficiently transmit the tension of the tension applying means to the wearer's body, only the both ends of the tension applying means are the lower part. It is preferable that it is fixed to the garment body and the middle part is separated from the garment body. Furthermore, in order to be able to adjust the tension of the tension applying means according to the physical condition and ability of the wearer, it is preferable that both ends of the tension applying means are fixed in a detachable manner from the lower garment body.

  As means for adjusting the tension of the tension applying means, (I) a method of changing a length between the fixed portions of the tension applying means and the lower garment body (that is, a length of the non-fixed portion); II) Two methods using the tension applying means using fabrics having different elongation stresses can be exemplified. The former method (that is, a method of changing the length between the fixing portions of the tension applying means and the lower garment body) partially stops the lower garment main body and the tension applying means such as a hook-and-loop fastener and a snap button. Secondary materials that can be worn are applicable. For example, a hook-and-loop fastener is provided in advance in at least one end of the tension applying means described above, a hook-and-loop fastener is provided in a corresponding portion of the lower garment main body, and the length and width of the hook-and-loop fastener provided in the lower garment main body are applied with the tension. If the hook-and-loop fastener is provided larger than the hook-and-loop fastener provided at the end of the means, tension is applied by adjusting the position of the hook-and-loop fastener provided on the lower garment body that fixes the hook-and-loop fastener provided at the end of the tension applying means. The distance between the fixed portions of the means can be adjusted, and as a result, the tension of the tension applying means can be adjusted. On the other hand, the latter method (method using the tension applying means using fabrics having different elongation stresses) prepares a plurality of tension applying means using fabrics having different elongation stresses, and the wearer's ability The tension of the tension applying means can be adjusted by selecting the tension applying means to be used depending on the condition.

  In addition, it is desirable that the coefficient of static friction between the lower garment main body and the portion of the tension applying means not fixed to the lower garment main body is low. Since the lower garment of the present invention uses the force to return to the original length of the tension applying means to promote assistance during walking, the lower garment main body and the lower garment main body of the tension applying means When the coefficient of static friction between the unfixed portion and the non-fixed portion is high, the tension in the longitudinal direction of the tension applying means is not transmitted well, and the joint motion is prevented from being induced. Therefore, it is desirable that the coefficient of static friction between the lower garment body and the lower garment body of the tension applying means and the unfixed portion is 0.3 to 0.7. The lower limit of the coefficient of static friction between the lower garment body and the garment body that is not fixed to the lower garment body is lower in theory, but the lower limit is better. It is preferable that the numerical value is 0.3 or more, since the upper limit value of the static friction coefficient of the lower garment body and the lower garment body and the portion of the tension applying means that is not fixed does not hinder the induction of joint movement, It is preferable that it is 0.7 or less.

  The measurement method used in this example will be described later.

(1) Ratio of crotch length to crotch length and width at the top of the crest The flat garment body is placed flat on a desk in a non-wearing state, and is shown by 6 and 7 in FIG. Length (cm) and width (cm) were measured. Thereafter, the ratio of the placing dimension crotch length to the placing dimension upper end width was calculated by the following formula 1.
Formula 1 ... (ratio of placing dimension crotch length and placing dimension upper end width) = (climbing length) / (upper end width).

(2) Breaking elongation The breaking elongation of the fabric sample was measured using an autograph AG-50kNG manufactured by Shimadzu Corporation. Specifically, five test pieces cut to a width of 25 mm and a length of 220 mm were prepared, and then one of the five test pieces was separated by a distance between chucks of 100 mm and a pulling speed of 300 mm / min. The fabric was pulled until it broke, and the elongation at that time was measured. As used herein, “breaking elongation” refers to the average value of the breaking elongation of the five fabrics measured by the above method. Here, it sampled so that the length direction of a test piece might be the same as the height direction of the wearer of the said lower garment main body.

(3) Elongation stress The stress at 80% elongation of the fabric sample was measured using Autograph AG-50kNG manufactured by Shimadzu Corporation. Specifically, five test pieces cut to a width of 25 mm and a length of 220 mm were prepared, and then one of the five test pieces was separated by a distance between chucks of 100 mm and a pulling speed of 300 mm / min. The fabric was pulled until it broke and the elongation stress at each elongation was measured. As used herein, “elongation stress” refers to an average value of elongation stress when the elongation of the five fabrics measured by the above method is 80%. Here, it sampled so that the length direction of a test piece might be the same as the length direction of the means pulled in the wearer's height direction of the said garment main body.

(4) Coefficient of static friction The coefficient of static friction of any surface of the fabric sample was measured according to JIS P8147: 1994 3.2 tilt method. Three test pieces having a width of 25 mm and a length of 130 mm were prepared. Next, one of the three test pieces was attached to an 872 g weight of a sliding inclination angle measuring device. On the other hand, a rubbed object having a width of 120 mm and a length of 200 mm is attached to a sliding inclination angle measuring device, and the weight of the test piece is attached so that the measurement surface of the test piece comes into contact with the rubbed object, and the length of the test piece. On the rubbed body so that the direction and the sliding direction of the sliding inclination measuring device coincide with each other, read the inclination angle when the weight falls under the condition that the inclination angle is less than 3 ° / second, The tangent (tan θ) was taken as the coefficient of static friction. The static friction coefficient was measured for the other two test pieces in the same manner as described above, and the average value of the measured values of the static friction coefficients for the three sheets was taken as the static friction coefficient. Here, sampling is performed so that the length direction of the test piece is the same as the direction in which the tension of the tension applying means works. Moreover, what is used as the rubbed body is the cloth of the part not fixed to the lower garment body of the tension applying means of the lower garment body, and the direction of the fabric of this cloth is the same as the height direction of the wearer. Sampled.

(5) Evaluation of the lowering effect of the lower garment About the lowering effect of the lower garment when the lower garment obtained in each of the examples and the comparative examples is worn and the walking motion is performed for 1 minute, by 10 subjects. Each person's absolute evaluation was evaluated with a maximum of 10 points, and the evaluation was made according to the following criteria from the average score of 10 people (rounded off after the decimal point).
