Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure distribution measuring device used for designing clothes worn so as to directly or indirectly adhere to a body.

[0002]

2. Description of the Related Art An important factor in designing clothes such as underwear which is directly or indirectly attached to the body is that a comfortable wearing sensation is obtained when worn. The quality of wearing also affects the degree of swelling and fatigue of the body that can occur when wearing clothes for a long time. Such wearing feeling is due to the material characteristics of the material,
It depends on the three-dimensional shape of the product and the shape and constitution of the target part of the human body.

Conventionally, when a prototype is evaluated in the stage of product development such as underwear, the above-described wearing feeling is also evaluated by the fitting, and the shape of the product is corrected based on the result, and the wearing is further improved. It is being done to make products with excellent feeling.

Further, in the development of products such as shoes, chairs and beds which directly or indirectly contact the human body, the pressure applied to each part is measured by using a plurality of pressure sensitive sensors, and image processing is performed to detect the pressure. A device for displaying a two-dimensional distribution has been proposed (for example, see Japanese Patent Laid-Open No. 7-55607).

[0005]

In the development of clothes such as underwear, in order to improve the efficiency of the cycle of trial manufacture, evaluation, and design change, before the qualitative and final evaluation by fitting on the human body, It is desirable to perform quantitative and reproducible evaluation using some kind of device without being affected by errors due to individual differences and physical conditions. However, there has been no such evaluation device in the past. Even if the above-described pressure distribution measuring device for developing shoes, chairs, beds, etc. is applied to the development of clothes, it cannot be diverted as it is.

For example, in the above-mentioned conventional apparatus, the pressure-sensitive sensors are arranged at equal intervals on a product or the like, the obtained data is processed, and the outline of the weighted portion is displayed as a contour. On the other hand, in clothes such as underwear, in which part of the three-dimensional human body, such as the skeleton and muscles, the pressure is concentrated, or is the pressure evenly distributed throughout the body? It is necessary to evaluate how much pressure is applied to each part that may or may not be applied with pressure, and such evaluation data cannot be obtained by the above device. In other words, it is necessary to solve the problems peculiar to the layout of the pressure sensor, the display method of the pressure distribution, and the development of clothes such as underwear.

In view of the above situation, the present invention accurately measures the human body part to which pressure is applied when wearing clothes and the degree of pressure in the research and development of clothes such as underwear in which the feeling of wearing the body is important. The present invention provides a pressure distribution measuring device and a measuring method capable of accurately knowing how it affects the human body and visually displaying the pressure distribution by data processing of measured values. To aim.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the pressure distribution measuring apparatus according to the present embodiment includes a plurality of pressure-sensitive sensors 2 provided at predetermined locations on the surface of the human body model 1, the detection signals of these sensors from a multiplexer 3 and a GP-. IB
A personal computer 5 that inputs through the interface 4 and processes it to calculate a pressure distribution, and a printer (or plotter) 6 that prints out the obtained pressure distribution are provided. The computer includes a keyboard and a mouse for inputting numerical values and setting conditions, an auxiliary storage device (hard disk) for storing files such as input data, a display for displaying the obtained pressure distribution and the like.

As the human body model 1, in addition to the whole body model, an upper body model (top) model, a lower body model (bottom) model, a leg model, etc., which are convenient to handle, are prepared. In addition to the standard body shape,
It is preferable to prepare several types of body types such as lean type and obese type. In the measurement examples described later, a standard body type bottom model and a leg model were used. Although the material used is made of hard resin, a human body model made of a material having elasticity close to that of a human body may be used in measurement for molding evaluation such as bust-up.

The pressure-sensitive sensor 2 is a sensor capable of taking out a change in pressure applied to the sensor as an electric signal, and a sensor which can obtain a voltage by the piezo effect, a sensor which can change a resistance value like a conductive resin, Various pressure-sensitive sensors can be used such as those that can obtain a change in capacitance. In the measurement example described later, the diameter is 6 mm and the thickness is about 2
A sensor was used in which a hemispherical silicon rubber pressing member was attached to one surface of a disk-shaped piezoelectric element having a size of mm. 50-
Sixty sensors were embedded in predetermined positions of the manikin so that the rubber pressing member would protrude from the surface, and the respective lead wires were pulled out through the manikin.

Although the number of sensors depends on the number of input channels of the multiplexer 3, it is possible to increase the number of sensors by using a plurality of multiplexers. However, if the distance between the adjacent sensors is too close to each other, pressure is exerted on each other through the clothes, and it becomes impossible to obtain a measured value close to the pressure distribution when the clothes are actually put on the human body.

Therefore, it is necessary to keep the number of sensors to a minimum, and to arrange the sensors in the most appropriate place depending on the type of clothes to be worn, the part of the human body to be worn, the purpose of wearing, etc. It is preferable to determine the sensor arrangement from the following viewpoints.

1) A part that is meaningful when viewed from the shape of the body,
For example, the sensor is arranged at a portion that is raised in a stationary state, a portion that is raised as the body moves, and a portion that has a skeleton just below the skin. The pressure of clothes is often concentrated on such a part, and if the pressure is too large, discomfort or discomfort is caused. Therefore, the above sensor arrangement is important for developing and designing clothes that fit the body without causing discomfort or discomfort. Further, a higher pressure is often applied from clothes to the part that is raised in accordance with the movement of the body, and the pressure causes more discomfort and discomfort, and may hinder the movement of the body. Therefore, it is meaningful to know the pressure distribution in such a part for the design and development of underwear that is continuously worn on a daily basis. In addition, it may be important to evaluate how different pressures are applied between areas having different curvatures, for example, the abdomen and the side.

2) A sensor is arranged at a portion related to molding and movement, for example, a portion such as a bust where a large amount of fat causes a morphological change due to external pressure or a portion where the amount of movement of skin is large. For example, it is important to know the pressure distribution of such a part for the design / development of a foundation that produces a molding effect such as bust-up, or for the design / development of clothes that are easy to move.

3) A site that is physiologically changed by an external stimulus, for example, a site where blood vessels and nerves (including sensory organs such as tactile senses) are concentrated, a site that is most fatigued by an operation, and a center of a muscle. And place the sensor in the surrounding area. In order to eliminate discomfort when wearing clothes, it is necessary to suppress the irritation of the clothes to the skin and prevent pain and blood flow obstruction. Therefore, it is important to know the pressure distribution in the above parts for the design and development of clothes that emphasize health and comfort.

4) In addition, a site having a psychological change due to an external stimulus is also an important site for evaluating the pressure distribution when wearing clothes. When actually measuring the pressure distribution with this device in the design and development of clothes, combine the above multiple points according to the application of the clothes, the purpose of development, etc., and place the sensor at an appropriate site. become. If desired, sensors may also be placed at equal points between the above sites.

Next, the multiplexer 3 has a large number (for example, 6).
The electrical signal from (0) sensor 2 is divided into a plurality of channels, and GP-I is selected while switching the channels at high speed.
Pass to B interface 4. The GP-IB interface 4 is a general-purpose parallel interface widely used for measuring instruments.

The personal computer 5 is installed with software for processing signals from a large number of pressure sensitive sensors 2 and calculating a pressure distribution. This software is divided into three programs that run on Windows (trademark of Microsoft Corporation) that is OS software.

One of them is a program for temporarily storing a set of measurement data obtained by a plurality of sensors as one data file in the auxiliary memory (hard disk) of the computer 5. The outline of the processing executed by this program is shown in the flowchart of FIG. In the process “setting of input type etc.” in step 101, the type of sensor, measurement range, etc. can be set for each channel. "Initial balance" in step 102 is a process for performing zero adjustment of the sensor at high speed for each channel. In step 103, the name of the data file to be recorded is input, and in step 104, recording start is instructed to execute recording. Then, a data file having the file name specified in step 105 is created in the hard disk.

The second program is a data conversion program. As shown in the flowchart of FIG. 3, the data file and the sensor position data file recorded on the hard disk are read out, and a pressure distribution data file is created from these data. In the process of "input of conversion conditions" in step 201, a target file among the data files recorded on the hard disk is designated, the file name of the converted pressure distribution data file is input, and the conversion format is input.

When a conversion start command is issued in step 202, first, in step 203, the designated data file is read from the hard disk. Further, in step 204, a file of position (x, y, z) data of each sensor is read. Then, the pressure distribution data is created from these two files. Regarding the distribution viewed from the front, the distribution viewed from the back, and the distribution viewed from the side, step 205, step 206, step 207.
Are created in sequence. The three generated distribution data are put together into one file in step 208 and stored in the hard disk with the designated file name.

The third program, as shown in the flow chart of FIG. 4, performs a pressure distribution drawing process. Of the pressure distribution data files created and saved by the second program, the file for which the pressure distribution is to be displayed (drawn) is specified in step 301, and step 3
If the file name is confirmed in 02, next step 3
In 03, the drawing condition setting screen is displayed. Here, designation of a drawing output destination (screen or printer) and switching between isobar display and color pattern display (or grayscale display) can be set. Further, it is possible to set whether to display the pressure distributions of the front, back, and side surfaces side by side, or to display only the pressure distribution of any one surface. The setting of whether or not to display the sensor arrangement with dot marks is also performed here.

When the setting contents of the drawing conditions are confirmed in step 304, the designated pressure distribution data file is read in step 305, and the pressure distribution is determined in step 306 according to the pressure distribution data. (Or gray scale). Next step 30
In the “guideline drawing” process of 7, the contour of the human body model is drawn. It is also possible to draw the outline of the clothes. Further, it is judged in step 308 whether or not the mark display of the sensor arrangement is designated. If it is designated, the position of each sensor is written as a dot mark in step 309.

Next, an example of drawing output using the above-described pressure distribution measuring device is shown in the drawing. As a first example, FIG.
The printout of the pressure distribution shown in Fig. 7 is from the front when the pantyhose is attached to the lower half of the mannequin,
It is the measurement result of the pressure distribution seen from the back surface and the side surface. In the actual printout, the change in pressure is blue (minimum pressure)
From the above, a color pattern is displayed as a continuous change from green to yellow to red (maximum pressure). However, because it is not possible to display in color here, gradation is displayed according to the density of dots and the pressure is set to 4 for convenience. The isobar at the boundary is divided into stages and displayed as thin lines.

Further, in FIGS. 5 to 7, the position of the sensor is indicated by a dot mark. As described above, this sensor arrangement was determined in consideration of the body shape, molding, and physiological changes due to external stimulation. In the figure, the unit of the number written on the bar graph showing the pressure change is [mmHg], and the unit of the number showing the position on the horizontal axis and the vertical axis of the pressure distribution pattern is [cm]. is there.

As a second example, as shown in FIGS. 8 (a) and 8 (b), FIG. 9 shows the measurement result of the pressure distribution when the girdle is attached to the bottom model, which is displayed on the screen.
In this example, the pressure distribution viewed from the front is displayed at the center of the screen, the pressure distribution viewed from the side is displayed on the left side, and the pressure distribution viewed from the back is displayed on the right.

In this example as well, the pressure distribution is actually displayed visually in a more understandable manner, but in this figure, instead of the color pattern, gradation is displayed by the density of dots and the pressure is displayed. For convenience, the isobars at the boundaries are displayed in thin lines in four stages. As can be seen from the pressure distribution viewed from the front, when the girdle is worn, the pressure applied to the body is relatively evenly distributed from the center of the abdomen to the periphery. Although illustration is omitted,
By comparing with the pressure distribution obtained when wearing other girdles, it becomes clear that there is a great difference in the distribution of pressure exerted on the body depending on the design and material of each product. In comparison with the pressure distribution shown in FIG. 9,
In some products, it is clear that the pressure is concentrated on a specific area.

Instead of measuring the pressure distribution using a human body model having sensors arranged as in the above embodiment, the sensors are directly attached to a plurality of predetermined positions on the human body to measure the pressure distribution. You may.

Since it can be displayed on the screen or printed out, the efficiency of the cycle of trial production, evaluation, and design change of clothes can be improved, and the objectivity of evaluation results can be ensured. As a result, there is no discomfort or discomfort,
It can contribute to the efficient development and design of clothes that fit the body.
