Abstract

PURPOSE:To measure the pressure of clothing such as panty hose and socks at an important position relevant to a feeling of wearing by fixing a small-sized pressure sensor on the surface of a dummy leg body and leading the output of the pressure sensor out to a pressure detecting device. CONSTITUTION:An aluminum-made molding of standard size of a Japanese female is used for the dummy leg body 1, and small-sized pressure sensors 2 are embedded at plural positions of the arch, ankle, calf, femur, etc., of the foot. The outputs of the pressure sensors 2 are led to a multichannel strain amplifier 4 through the connector of a stage 3 and recorded on a recorder 5. When a measurement is taken, this dummy leg body 1 is covered with a body to be measured, the pressure sensors 2 detect pressure operating on the dummy leg body 1 owing to the elastic deformation of the body to be measured, etc., and their outputs are amplified by the strain amplifier 4 and recorded on the recorder 5.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a device for measuring wearing pressure, and particularly to a device for measuring pressure when wearing clothing such as pantyhose, socks, pants, and slacks.

(Prior Art) Conventional instruments for measuring pressure when wearing clothing include, for example, devices that directly measure pressure from changes in the internal pressure of a sachet filled with fluid. For example, a device has been proposed that directly measures the pressure when clothing is being worn, based on changes in the internal pressure of a pouch filled with fluid. There are some problems with this method, such as ■ inserting the sensor changes the state of clothing worn, ■ the sensor is small and embeds itself in the human skin, and ■ the sensor's installation position cannot be fixed. It is difficult to say that the measurement was accurate.

In addition, a pressure measuring device exclusively for stockings using a leg wall model has been proposed, such as the LED ICA IStok introduced by Tokyo Shock Research Institute Co., Ltd.
ing Te5ter (made in West Germany). However, in this measuring device, the circumference of each of the four parts of the leg-shaped part, which is made up of a combination of simple cylinders with uniform curvature that approximates the thickness of each part of the leg, is the ankle, calf, below the knee, and thigh. It only measures a representative point, and cannot know the actual distribution of pressure around the ankles, calves, below the knees, and thighs when wearing clothing such as pantyhose, socks, pants, and slacks. . In other words, the actual leg is composed of a complex curved surface, and when wearing stockings, the area around the ankle, such as the ankle side and the Achilles skin side, and the area around the calf, such as the shin side and the calf side, are actually curved. Despite the fact that the pressure acting on the legs is different, there is a problem in that it is not possible to obtain detailed pressure values for each part of the leg when measuring using this measuring device.

(Problems to be solved by the present invention) The present invention solves the problems of pantyhose, socks, pants,
The above-mentioned drawbacks of conventional methods of measuring pressure on clothing such as slacks, namely, the inability to obtain quantitative and accurate measurement values because the installation state of the sensor cannot be determined, and the detailed pressure values for each part of the leg cannot be obtained. It is an object of the present invention to provide a device for quantitatively measuring pressure at a region of the leg, which has an important relationship with the actual feeling of wearing the above-mentioned clothing.

(Means for Solving the Problem) That is, the present invention provides a standard-sized pseudo leg having at least one pressure sensor on the surface of the pseudo leg;
This is a wearable pressure device characterized by comprising a pressure detection device connected to a pressure sensor.

FIG. 1 is a configuration diagram of a wearing pressure measurement device of the present invention. A model leg body 1 in which a plurality of small pressure sensors 2 are embedded, a stage 3 to which a connector is attached to which the model leg body 1 is fixed and which transmits the output from the small pressure sensors 2 to the outside, and an output from the small pressure sensors 2 is installed. It consists of a multi-channel strain-up 4 for a small pressure sensor that amplifies and a multi-channel recorder 5 that records the output.

The pseudo leg body 1 is desirably made of a material such as metal or resin, approximates the curved shape of a human leg, and is of a standard size (for example, the standard size of a Japanese woman). It is desirable that the pressure sensor 2 is thin and has a small pressure receiving area, and since the sensor output varies depending on the pressure receiving area, the pressure sensor 2 should have a diameter of 3
Cylindrical chips of ~101 m are preferred. The pressure sensors may be installed anywhere on the surface of the pseudo leg body 1, but multiple pressure sensors may be installed around specific positions where pressure is applied when wearing clothing such as pantyhose, socks, pants, slacks, etc. It is desirable that a plurality of such devices be installed around the arches, ankles, calves, and thighs. It is desirable that the stage 3 has a larger base area than the pseudo leg 1 so that the pseudo leg can stand in a stable state. It is desirable that a plurality of connectors be attached to the stage 3 so that the output of the small pressure sensor 2 can be input to the strain up tube 4 so that the output of the small pressure sensor 2 can be simultaneously amplified by the plurality of small pressure sensors. In addition, strain up 4
For example, a multi-channel recorder is used to display the output from.

(Function) FIG. 2 is a schematic diagram for explaining the measurement method. An object to be measured is placed on a pseudo leg 1 equipped with a small pressure sensor 2, and the pressure generated by the object is measured at multiple positions around the arch, ankle, calf, and thigh of the pseudo leg 1. This indicates the state in which the The pressure acting on the pseudo leg body 1 due to elongation and deformation of the object to be measured is detected by multiple small pressure sensors 2 installed on the surface of the pseudo leg body 1, and this output is amplified by the multi-channel stocking and tube 4. and record it with a multi-channel recorder 5.

(Example) An apparatus according to the present invention was prepared as follows, and four sample socks shown in Table 1, in which only the fineness of the polyurethane elastic yarn was changed, were measured.

For the pseudo leg body 1, an aluminum molded body having the standard actual size of a Japanese woman was used. In the pseudo leg body, small pressure sensors were installed at 1 location on the arch, 4 locations around the ankle, 4 locations around the calf, and 4 locations around the thigh.
These three locations represent important positions where pressure is applied when wearing clothing such as pantyhose, socks, pants, and slacks. As the small pressure sensor 2, a PS-B type ultra-small pressure transducer manufactured by Kyowa Dengyo Co., Ltd. was used. A hole with a diameter of 6.0+n is made in the pseudo leg body 1, and the outer diameter of the hole is 5.0 mm to prevent the lead wire from breaking. O■嘗, length 15.
The above-mentioned small pressure sensor reinforced with an On+ aluminum sleeve was adhesively fixed with epoxy resin. Thirteen connectors are attached to the stage 3 and connected so that the output of the small pressure sensor 2 can be input to the strain up 4, and the output line from the strain up 4 is connected to the hybrid
It was connected to a recorder 5 (manufactured by Nippon Denshi Kagaku Corporation; H-1030).

Further, Table 2 shows the pressure measurement results at each location according to the g position described above. It was found that the greater the fineness of the polyurethane elastic yarn, the greater the pressure measurement values in general. Furthermore, the relationship between the measurement location and the pressure value revealed that the pressure was not uniform around the ankle, calf, and thigh.

FIG. 3 shows the sensory values (average values) obtained by 14 subjects for the samples used in this example. It was revealed that there was a good relationship between the pressure measurement values of the four samples in Examples and the sensory values of pressure sensation.

Polyurethane nylon sample 1 10d 10d Sample 2 20d lod Sample 3 30d 10d Front nylon 12d x 3 12d IcalS
The sites shown in Table 3 were measured using a tacking Te5ter (manufactured in West Germany). This measuring device is a model leg body that takes into account only the thickness of the leg, and although it can obtain the relationship between the pressure measurements of ankle, calf, and thigh, it does not know the pressure value and its distribution state in the circumferential direction of the leg. I can't.

It has become clear that since a model leg body with a shape close to that of a human leg is used in this test, measurement values of more detailed parts of the leg can be obtained than the measurement results of the comparative example.

Table 3 Unit: (gf/+() (Effects of the Invention) According to the present invention, since the small pressure sensor is fixed to the surface of the pseudo leg body, quantitative measurement values with good accuracy and reproducibility can be obtained. , it is possible to measure detailed pressure values around specific parts of the leg, which have an important relationship with the feeling of wearing clothes (comfort, comfort, etc.) in actual clothing.Pressure measurement using the wearing pressure measuring device of the present invention An excellent effect is obtained in that the values almost correspond to human sensory values.In addition, the material and composition of the product can be determined based on the pressure value and its distribution state around the specific leg area, which could not be obtained with conventional measurements. Utilizing the measuring device for the purpose of improving conditions and even design,
There is a possibility that new and comfortable products can be researched and developed.
