  FIG. 1 is a diagram illustrating an appearance of a clothing evaluation device 1 according to an embodiment of the present invention.

  The clothing evaluation device 1 measures the motion of a person (hereinafter, referred to as a wearer) who wears clothing (clothing) to be evaluated for adaptability, and evaluates the adaptability of the clothing according to the measured motion of the wearer. It is a device to do.

  In the present embodiment, the clothing evaluation device 1 mainly evaluates the ease of movement of lower body clothing such as pants. The ease of movement referred to here is the functionality of the clothes that the clothes show for the human body movements of the wearer, and can also be referred to as the motion adaptability of the clothes to the human body movements.

  The clothing evaluation device 1 includes a measurement unit 10 and a processing unit 20. A terminal 30 that controls the operation of the processing unit 20 is connected to the clothing evaluation device 1. Further, the clothing evaluation device 1 may include a terminal 30 that is connected to the processing unit 20 by wireless or wired.

  The measurement unit 10 has a horizontal measurement table 11 on which a wearer rides, and measures a change in load applied to the measurement table 11 by the wearer. Further, the measuring unit 10 measures the weight of the wearer.

  The processing unit 20 includes a storage device such as a ROM (Read Only Memory) and a RAM (Random Access Memory), a CPU (Central Processing Unit), an input / output interface, and a bus connecting these components to each other. . The processing unit 20 controls the operation of the clothing evaluation device 1 via the input / output interface by reading a control program stored in the storage device and causing the CPU to execute the control program.

  The processing unit 20 is connected to the measuring unit 10 by a cable 25. The processing unit 20 evaluates the ease of movement of the clothes based on the change in the load of the wearer measured by the measuring unit 10 and displays the evaluation result. The processing unit 20 may be configured by, for example, a mobile phone, a smartphone, a server, or the like.

  In addition, about the processing part 20, a support | pillar may be attached to the measurement part 10, and it may be attached to the upper part of this support | pillar, and may be connected via wireless. Further, the measurement unit 10 and the processing unit 20 may be integrated, or the processing unit 20 and the terminal 30 may be integrated.

  FIG. 2 is a block diagram illustrating a configuration of the clothing evaluation device 1 according to the present embodiment.

  The measurement unit 10 includes a load sensor 12 that detects a load, and a load calculation circuit 13.

  The load sensors 12 are arranged at four corners of the rectangular measuring table 11. The load sensor 12 includes, for example, a load cell. The load cell includes a flexure element that deforms in accordance with an input load, and a strain gauge attached to the flexure element, and the strain gauge is an electric signal indicating a value corresponding to the deformation of the flexure element ( Detection signal).

  Regarding the load sensor 12, it is preferable to incorporate a plurality of load sensors 12 in the measuring unit 10 in order to suppress a variation in the load measured at the position where the load is applied on the measuring table 11. In this embodiment, four load sensors 12 are incorporated. Each of the load sensors 12 generates a detection signal corresponding to a load acting vertically on a portion of the measuring table 11 where the load sensor 12 is installed.

  The load sensor 12 is connected to a load calculation circuit 13. When the wearer gets on the measuring table 11 of the measuring unit 10, the load applied to the measuring table 11 is detected by each load sensor 12. Each load sensor 12 outputs a detection signal corresponding to the load to the load calculation circuit 13.

  The load calculation circuit 13 calculates a load applied to the measuring table 11 based on a detection signal output from each load sensor 12. The load calculation circuit 13 generates load data indicating the calculated load in time series and outputs the generated load data to the processing unit 20.

  The processing unit 20 includes a plurality of operation switches 21, a display screen 22, an output port 23, and a CPU 24.

  The operation switch 21 is a switch for inputting ON / OFF of the clothing evaluation device 1, wearer information, a measurement start instruction, and the like. The wearer information referred to here includes, for example, the type of clothes of the wearer, the age, sex, weight, and height of the wearer.

  The display screen 22 displays a command, information, an evaluation result, or the like input according to an operation of a wearer or a measurer.

  The output port 23 can transmit the clothing evaluation result to the terminal 30, as shown in FIG.

  The CPU 24 is a control device that controls the clothing evaluation device 1 overall. The operation switch 21, the display screen 22, and the output port 23 are connected to the CPU 24. Further, the CPU 24 is connected to the load calculation circuit 13 in the measurement unit 10 via the cable 25.

  FIG. 3 is a block diagram illustrating a functional configuration of the CPU 24 according to the present embodiment.

  The CPU 24 includes a data acquisition unit 241, a clothing determination unit 242, and a determination information generation unit 243.

  The data acquisition unit 241 forms an acquisition unit that acquires load data of the wearer. The data acquisition unit 241 according to the present embodiment acquires load data output from the load calculation circuit 13 and acquires wearer information input via the operation switch 21.

  The clothing determination unit 242 forms a determination unit that determines the ease of movement of the clothing based on the load data of the wearer. The clothing determination unit 242 of the present embodiment includes a motion index calculation unit 242A and a movement ease determination unit 242B.

  The operation index calculation unit 242A constitutes a calculation unit that calculates an operation index related to the wearer's movement based on the load data of the wearer. As the motion index, for example, a quickness index relating to the quickness of the rising motion performed by the wearer on the measuring table 11, a power index relating to the power of the motion, a quickness index and a power index, And an overall evaluation index that takes both of these into consideration. As described above, the motion index that is likely to be affected by the ease of movement of the clothes to be worn is used.

  The ease-of-movement determining unit 242B constitutes a determining unit that determines whether the motion index exceeds a predetermined threshold. The movement ease determination unit 242B determines that the wearer's clothes are easy to move when the movement index is higher than the predetermined threshold, and moves the wearer's clothes when the movement index is equal to or lower than the predetermined threshold. It is determined to be difficult.

  The predetermined threshold mentioned here is predetermined based on the action of the wearer when wearing specific clothes. When the evaluation target is a new product suit, the specific clothing is, for example, an existing suit, a standard suit, a suit of the same type, and the like. Note that the ease of movement determination unit 242B may set a predetermined threshold value for each degree of ease of movement. This makes it possible to make a stepwise determination on the ease of movement.

  In the present embodiment, the predetermined threshold is changed according to the wearer information. For example, in the case where the numerical value of the quickness index increases as the wearer moves faster, the ease-of-movement determining unit 242B increases the predetermined threshold value as the wearer's age increases. This makes it possible to determine the easiness of movement of the clothes in consideration of the tendency of movement due to the age, gender, age, etc. of the wearer. Further, the threshold value may be set in consideration of the purpose or target of the clothes. For example, a higher threshold may be set for clothing for the elderly as compared to clothing for the young.

  The determination information generation unit 243 forms a generation unit that generates information regarding the ease of movement of the clothing using the determination result of the clothing determination unit 242. The determination information generation unit 243 according to the present embodiment generates determination information indicating a determination result as to whether the clothing is easy to move or an evaluation value of ease of movement.

  The evaluation value of the ease of movement is calculated, for example, according to the difference between the wearer's motion index and a predetermined threshold. Alternatively, the determination information generation unit 243 may store a conversion map indicating the relationship between the numerical value of the operation index and the evaluation value in advance, and calculate using the conversion map.

  In the present embodiment, each function of the data acquisition unit 241, the clothing determination unit 242, and the determination information generation unit 243 is executed by one CPU 24, but each function may be executed by using a plurality of CPUs.

  Next, a description will be given, with reference to FIGS. 4 and 5, of a method of determining the ease of movement of clothing by the clothing evaluation device 1.

  FIG. 4 is a diagram illustrating the operation of the wearer A when determining the ease of movement of the clothes.

  First, the chair 40 is arranged adjacent to the clothing evaluation device 1. Then, as shown in FIG. 4A, the wearer A sits on the chair 40 with his / her feet on the measuring stand 11 of the measuring unit 10.

  Subsequently, as shown in FIG. 4B, the wearer A stands on the measuring table 11 from a state of sitting on the chair 40. Then, as shown in FIG. 4 (c), the wearer A waits until the body has stabilized and has stabilized.

  As described above, while the wearer A is performing the rising operation, the load calculation circuit 13 obtains the change in the load accompanying the rising operation of the wearer A based on the detection signal from the load sensor 12, and calculates the load fluctuation. Output to CPU24. As described above, the load calculation circuit 13 measures the operation of the wearer A rising from the sitting state.

  FIG. 5 is a diagram showing, in chronological order, a change in load on the measuring table 11 due to the movement of the wearer A shown in FIG. FIG. 5 shows the operation of the wearer A during the measurement shown in FIG. 4 for easy understanding.

  When the wearer A sits on the chair 40 and puts his or her feet on the measurement stand 11 to start the rising motion (the state where the wearer A is sitting on the chair 40), the load decreases at the point P, and thereafter, the point Max , The load becomes the maximum value F. This is because the overall weight of the wearer A is applied to the measurement table 11 and the force of the wearer A is applied to the measurement table 11 because the wearer A stands up from the chair 40.

  Then, after the load reaches the maximum value F at the point Max, the load of the wearer A becomes smaller than the actual weight Wt of the wearer A, and reaches the minimum value at the point Min. This is because the load acting on the measuring table 11 at the timing when the knee of the wearer A is fully extended is reduced due to the reaction when the wearer A steps on to stand up. After that, while returning to the actual weight Wt and rising and falling, the amplitude is attenuated and converges to the actual weight Wt.

  Utilizing such a change in load, the clothing evaluation device 1 calculates a quickness index and a strength index having a correlation with the ease of movement of the clothing. Then, the clothing evaluation device 1 can determine the ease of movement of the clothing worn by the wearer A by using these motion indices.

  In the present embodiment, the functionality of the clothes is determined by using the load fluctuation caused by the action of the wearer A sitting on the chair 40 and standing up. However, the present invention is not limited thereto. Instead, a rising operation may be performed from a squatting state. In this case, the physical burden becomes too large for the wearer A to be elderly or weak. Therefore, by using the chair 40 as in the present embodiment, the burden on the wearer A can be reduced.

  Next, a method of calculating the quickness index, the strength index, and the comprehensive evaluation index used for determining the ease of movement of clothes will be described in detail.

(1) Strength index When the CPU 24 acquires the load data output from the load calculation circuit 13, the CPU 24 obtains the maximum value F of the load as shown in FIG. A strength index is calculated based on the weight Wt.

  For example, the CPU 24 may calculate a difference or a ratio between the maximum value F of the load and the actual weight Wt as the strength index. Alternatively, the CPU 24 may obtain a difference ΔF between the minimum value and the maximum value F after the load reaches the maximum value F, and calculate the difference or ratio between the difference ΔF and the weight Wt as a strength index. .

  Alternatively, the CPU 24 may calculate the strength index by comparing the minimum value after the load has reached the maximum value F with the minimum value of the load data acquired in the past. As the minimum value becomes larger than the past minimum value, the numerical value of the strength index is increased. Alternatively, the CPU 24 may similarly calculate the strength index by comparing the obtained load with the maximum value F and the maximum value of the load data acquired in the past.

  In the present embodiment, the CPU 24 calculates a maximum value weight ratio (F / Wt) obtained by dividing the maximum value F of the load by the actual weight Wt as a strength index. Note that the CPU 24 may multiply the maximum value weight ratio (F / Wt) by a specific conversion coefficient so that the numerical value of the strength index falls within a predetermined range.

  Regarding the strength index of the present embodiment, when the clothes of the wearer A are easy to move, a great force is exerted by the wearer A stepping on the body 40 to move the weight from the chair 40 to the measurement table 11. 11, the maximum value weight ratio (F / Wt) increases. On the other hand, when the clothes are difficult to move, the action of strongly stepping on the clothes is inhibited by the pressure and resistance of the clothes, the force applied to the measuring table 11 is suppressed, and the maximum value weight ratio (F / Wt) decreases. .

  Therefore, the numerical value of the strength index increases as the clothes of the wearer A move more easily, and the numerical value of the strength index decreases as the clothes of the wearer A move harder.

  Further, a parameter used for calculating the strength index may be selected using the wearer information. For example, when the wearer A has weak muscle strength such as an elderly person, the maximum value weight ratio (F / Wt) may be selected as a parameter used for calculating the strength index. The reason is that when the muscle strength of the wearer A is weak, it is difficult to identify the point Min at which the load becomes the minimum value. Further, for example, when the type of clothes of the wearer A is sportswear, the difference weight ratio (ΔF / Wt) may be selected as a parameter used for calculating the strength index. The reason is that both the stepping force (maximum load F) and the degree of knee extension (minimum load) are reflected in the differential weight ratio (ΔF / Wt).

  Here, the point Max at which the load reaches the maximum value F corresponds to the time when the buttocks of the wearer A are separated from the chair 40. This point Max may also be difficult to specify in actual measurement. In the present embodiment, after detecting the point P at which the load becomes 20% or less with respect to the weight Wt, the maximum value F among a plurality of points at which the load becomes 105% or more with respect to the weight Wt is defined as a point Max. I do.

  Further, in the rising operation from the state of sitting on the chair 40, the load becomes light at the beginning of the operation, and thereafter, the load becomes the maximum value F. This is because when the wearer A tries to get up from the chair 40, the weight first moves to the buttocks of the wearer A, and the trigger is used to detect the point Max.

  In utilizing the characteristics of the rising motion of the wearer A, the point Max can be reliably specified by obtaining the maximum value F of the load as described above.

  The point P is a point at which the load decreases when the wearer A is sitting on the chair 40, but may be a point equal to or less than an arbitrary value such as 25% or 30% with respect to the weight Wt. Further, as the strength index, a maximum increase rate weight ratio (RFD / Wt) obtained by dividing the load change amount per unit time by the actual weight Wt may be used.

(2) Quickness index When the CPU 24 obtains the load data from the load calculation circuit 13, the CPU 24 obtains a period SP1 from the point P to the point Max as shown in FIG. 5, and calculates the quickness index using the period SP1. I do.

  For example, the CPU 24 may calculate the period SP2 from the point P to the point Min, and calculate the reciprocal of the period SP1 or the reciprocal of the period SP2 included in the period SP2 as the quickness index. Alternatively, the CPU 24 may calculate the reciprocal of the difference between the period SP1 and the period SP2 or the reciprocal of the ratio of the period SP1 to the period SP2 as the quickness index.

  In the present embodiment, the CPU 24 calculates the reciprocal of the period SP1 as a quickness index. Note that the CPU 24 may multiply the reciprocal of the period SP1 by a specific conversion coefficient so that the numerical value of the quickness index falls within a predetermined range.

  Regarding the quickness index of the present embodiment, when the clothes of the wearer A are easy to move, the wearer A can quickly get up from the chair 40, and thus the period SP1 is shortened. On the other hand, if the clothes are difficult to move, the period SP1 becomes longer because the wearer A takes time to stand up from the chair 40 due to the resistance of the clothes.

  Therefore, the numerical value of the quickness index increases as the clothes of the wearer A move more easily, and the numerical value of the quickness index decreases as the clothes of the wearer A move harder. Note that the period SP1 itself may be used as the quickness index instead of the reciprocal of the period SP1, and in this case, the value of the quickness index decreases as the clothes of the wearer A move more easily.

(3) Comprehensive Evaluation Index The CPU 24 calculates a comprehensive evaluation index indicating an evaluation value of ease of movement of clothes based on the strength index and the quickness index calculated as described above.

  For example, the CPU 24 weights at least one of the strength index and the quickness index in accordance with the contribution of each of the strength index and the quickness index to the ease of movement of the clothes.

  The CPU 24 of the present embodiment calculates the maximum value weight ratio (F / Wt) as a strength index, the reciprocal of the period SP1 (1 / SP1) as a quickness index, and a coefficient as in the following equation (1). The total evaluation index It is calculated using a, b, and c.

(Equation 1)
It = a × (F / Wt) + b × (1 / SP1) + c Expression (1)

  As can be seen from the equation (1), as the strength index (F / Wt) increases, the comprehensive evaluation index It increases, and as the quickness index (SP1) decreases, the comprehensive evaluation index It increases. I do.

  The coefficients a and b in Equation (1) are weighting coefficients determined according to the degree to which the strength index and the quickness index contribute to the ease of movement of the clothes. In the present embodiment, the coefficients a, b, and c are predetermined based on the group data measured by a specific person or a large number of persons so that the numerical value of the comprehensive evaluation index It falls within a range of 0 to 100. I have.

  Further, the coefficients a, b, and c may be set for each type of clothing of the lower body. For example, the types of clothes include suit pants, leather pants, and jeans. This makes it possible to accurately evaluate the ease of movement for each type of clothing.

  Then, the CPU 24 determines whether or not the comprehensive evaluation index It exceeds a predetermined threshold. The CPU 24 determines that the wearer's clothes are easy to move when the comprehensive evaluation index It exceeds a predetermined threshold, and the wearer's clothes hard to move when the comprehensive evaluation index It is equal to or less than the predetermined threshold. Is determined.

  Further, the CPU 24 generates determination information indicating a result of the determination. For example, the determination information includes the quality of the ease of movement of the clothes, the numerical value of the comprehensive evaluation index It, the numerical value of the quickness index, and the numerical value of the strength index. The CPU 24 displays the generated determination information on the display screen 22.

  Next, a method of displaying the determination result in the present embodiment will be described with reference to FIG.

  FIG. 6 is a diagram illustrating an example of the display screen 22. On the display screen 22, the numerical value of the comprehensive evaluation index It is shown as the total score of the ease of movement of the wearer A's clothes, and the determination result by the CPU 24 is shown. Further, a predetermined threshold value used for the determination is shown as the score of the conventional product. In this example, the determination result is indicated in three stages of （(good), △ (normal), and × (bad).

  Next, the operation of the clothing evaluation device 1 will be described with reference to FIG.

  FIG. 7 is a flowchart illustrating a processing procedure example of the clothing evaluation method according to the present embodiment. The CPU 24 of the processing unit 20 executes a program in which the clothing evaluation method is described.

  In step S1, the CPU 24 acquires load data indicating the load applied to the measuring table 11 in a time series while the wearer A is performing the rising motion.

  In step S2, the CPU 24 determines the ease of movement of the clothes based on the load data of the wearer A. The CPU 24 of the present embodiment calculates at least one of an index relating to the quickness of the rising motion of the wearer A and an index relating to the strength based on the load data of the wearer A. Then, if the calculated index exceeds a predetermined threshold, the CPU 24 determines that the clothing is easy to move.

  In step S3, the CPU 24 generates determination information regarding the ease of movement using the result determined in step S2. After that, the CPU 24 ends a series of processes for the clothing evaluation method.

  Next, the function and effect of the present embodiment will be described in detail.

  According to the present embodiment, the clothing evaluation device 1 includes the CPU 24 that evaluates the adaptability of the clothing according to the rising motion performed by the wearer A of the clothing on the measurement table 11. The CPU 24 acquires load data indicating the load applied to the measuring table 11 in a time series while the wearer A is standing up, and determines the ease of movement of the clothes based on the load data of the wearer A. Further, the CPU 24 generates determination information regarding the ease of movement of the clothes using the result of the determination.

  The inventors have found that the ease of movement of the clothes has a correlation with the standing motion of the wearer A. For this reason, in the present embodiment, the CPU 24 obtains a change in the load applied to the measurement table 11 while the wearer A is performing the rising operation, and thereby the rising operation caused by the ease of movement (adaptability) of the clothes. Can be detected. Thus, by detecting the fluctuation of the rising motion, it is possible to determine the ease of movement of the clothes worn by the wearer A.

  Further, the CPU 24 generates the determination information using the determination result, so that the wearer or the sales clerk of the clothes can easily grasp the ease of movement of the clothes.

  As described above, according to the present embodiment, the easiness of the movement of the clothing is determined by using the change in the load while the wearer A is performing the rising motion. This makes it possible to directly evaluate the ease of movement of the clothing itself. Therefore, for example, compared to a case in which the ease of movement of clothes is indirectly evaluated using a clothes pressure sensor, the ease of movement of the entire clothes is comprehensively and accurately evaluated without executing complicated arithmetic processing. can do.

  Further, according to the present embodiment, the CPU 24 calculates and calculates at least one of the index relating to the quickness of the rising motion of the wearer A and the index relating to the strength based on the load data of the wearer A. It is determined whether or not the index exceeds a predetermined threshold. Then, if the calculated index exceeds a predetermined threshold, the CPU 24 determines that the clothing is easy to move.

  The ease of movement of the clothes has a particularly high correlation with the quickness and strength in the rising motion of the wearer A. Therefore, by determining at least one of the index relating to the quickness and the index relating to the strength based on the load data of the wearer A, it is possible to accurately determine the ease of movement of the clothes.

  According to the present embodiment, as described with reference to FIG. 5, the CPU 24 calculates an index relating to strength based on the maximum value F of the load data of the wearer A and the weight Wt of the wearer A. In this way, by using the weight Wt of the wearer as a reference, the strength of the rising motion can be accurately evaluated.

  In addition, according to the present embodiment, the CPU 24 increases the numerical value of the comprehensive evaluation index It as the evaluation value of the ease of movement indicated by the determination information, as the numerical value of the index regarding the strength increases. Thus, it becomes possible for the wearer A to appropriately recognize the adaptability of the clothes according to the strength of the rising motion of the wearer A.

  According to the present embodiment, as shown in FIG. 5, the CPU 24 determines that the load is reduced when the wearer A stands up from the time when the load is reduced (point P) while the wearer A is sitting on the chair 40. The period SP1 up to the time when the maximum value F is reached (point Max) is obtained. Then, the CPU 24 calculates an index relating to quickness using the period SP1.

  The ease of movement of the clothes affects the length of time until the load applied to the measurement table 11 while the wearer A is standing up from the state in which the wearer A is sitting on the chair 40 is performing the rising motion. Cheap. For this reason, by using the period SP1 as the index relating to the quickness, the correlation between the index relating to the quickness and the ease of movement of the clothes is improved, so that it is possible to accurately determine the ease of movement.

  Further, according to the present embodiment, the CPU 24 increases the numerical value of the comprehensive evaluation index It indicated in the determination information as the period SP1 becomes shorter. Thereby, it becomes possible to make the wearer recognize the adaptability of the clothes accurately according to the quickness of the rising motion of the wearer A.

  Further, according to the present embodiment, as in the above equation (1), the CPU 24 weights the calculated indices according to the contribution of each index to the ease of movement. Accordingly, the contribution of each index is reflected in the numerical value of the comprehensive evaluation index It, so that the ease of movement of the clothes can be more accurately evaluated.
