JP6877126B2 - How to measure floating fingers using shoes and shoes - Google Patents

Description

The present invention relates to a shoe that allows the user to easily confirm whether or not the finger is a floating finger and can easily inform the user of the state of the toes during walking.

Motion analysis is performed by measuring the foot pressure distribution during the user's motion. For example, Patent Document 1 describes that a foot pressure distribution during walking is measured using a pressure sensor of a type installed on the floor, and a comparison with an ideal walking is performed from the obtained foot pressure center locus. ing. Further, as the pressure sensor, an insole type pressure sensor that can be attached to shoes is also known, and Patent Document 2 discloses a lightweight and compact insole type pressure sensor. The pressure sensor is connected to a personal computer or the like via a converter, and the software installed on the personal computer can measure, calculate, record, and display the trajectory of the center of gravity.

Foot pressure measurement systems such as those in Patent Documents 1 and 2 are not normally used by general users because they are expensive and require specialized knowledge to analyze the obtained data. .. In addition, measurements using insoles with sensors are used only for data collection, and few are generally used with shoes on.

On the other hand, it is well known that deformation of the foot such as hallux valgus / valgus valgus, flat feet, and floating fingers affects health and daily life (Non-Patent Documents 1 and 2).
Here, the floating toes indicate a state in which the toes are lifted from the ground in an upright position, and usually the heel, the forefoot (the base of the toes), and the toes support the weight, and the floating toes. A person with a toe supports his / her weight at two points, the heel and the forefoot. In the state where the body is supported by these two points, the center of gravity is biased toward the heel side, so that the body tends to move from side to side and the feet become unstable. In addition, this bias of the center of gravity tends to cause a difference between the left and right sides, and the body is distorted because it takes an unreasonable posture to compensate for this difference between the left and right sides. Examples of places where this distortion is likely to occur include the neck, back, hips, and knees. Furthermore, since the body can be supported only by two points, the impact from the ground cannot be sufficiently mitigated, and the body receives a strong impact. Then, the impact generated in walking in daily life, sports, etc. is repeatedly transmitted to the distorted part of the body, leading to chronic physical upset.
In this way, many people with floating fingers complain of problems such as knee pain, lower back pain, stiff shoulders, stiff neck, and headache caused by body strain, and because they do not usually use their toes, they have toes. It tends to lose its balance due to its weak treading force.

As a method of improving the floating finger, it is known that it is effective to correct the deformation of the foot with a supporter and to exercise the toe. In the movement of the toes, for example, in Patent Document 3, a flexible sheet obtained by excising the portion from the second to the fifth toes is used as an insole, and the toes are corrected by making the toes easy to move. Is disclosed.

However, in Patent Document 3, although the toe movement is promoted, it is unknown whether the toe is actually used, and it is not disclosed until it is determined whether the toe is a floating finger.

By Iwao Kasahara, "Stiff shoulders and back pain were caused by the" floating fingers "of the legs! , Sakurasha Co., Ltd., published on August 5, 2012 Iwao Kasahara, "Mom! Children's feet are dangerous!", Takarajimasha Co., Ltd., published on February 8, 2013.

Therefore, the present invention is for solving such a problem, and the user can easily confirm whether or not the finger is a floating finger, and the state of the toes during walking is simply notified to the user to cause the user to float. The purpose is to provide shoes that give interest to the fingers and eventually lead to prevention and improvement.

As a result of studies to solve the above problems, it was found that it is possible to determine whether or not a floating finger is a floating finger with a simple structure that only uses a pressure detecting means at a predetermined position, which led to the present invention. ..

That is, the present invention is a shoe provided with a means for determining whether or not it is a floating finger (hereinafter, referred to as a floating finger determining means), and the floating finger determining means is controlled by a base member provided with a pressure detecting means. A portion and a display portion are provided, and at least the base member is attached to the inner bottom portion of the shoe.
The pressure detecting means is arranged at a place corresponding to a mother toe, a place corresponding to one or more toes of any one of the 2nd to 5th toes, and a place corresponding to a ball of the mother toe, and the control unit is a mother. When a pressure above the threshold is detected from the electrical signal detected at the location corresponding to the ball of the toe, the location corresponding to the mother toe and the location corresponding to any one or two or more toes of the 2nd to 5th toes. It has a function of determining a floating finger based on whether or not a pressure equal to or higher than the threshold value is detected from the electric signal detected in the above and sending the result to the display unit, and the display unit transmits the result sent from the control unit. It is characterized by providing a means for notifying.

In the present invention, since the pressure detecting means is arranged at a predetermined position where it can be determined whether or not the finger is a floating finger, and the user can be notified that the detected pressure has reached the threshold value or more. The user can easily confirm whether or not the finger is a floating finger just by wearing the shoes of the present invention, and by simply informing the user of the state of the toes during walking, the user is made aware of walking using the toes. It can be expected to prevent and improve floating fingers.

The pressure detecting means of the present invention can be determined because are located in an area corresponding to the mother趾球, the presence or absence of ground mother趾球, whether lifting fingers more reliably.

In the present invention, the pressure threshold value may be set to two levels or more, and the notification content of the display unit may be changed accordingly. Then, the floating finger can be easily determined during walking.

The base member of the present invention may be an insole (insole) or an insole.

Further, the floating finger determination means may include a communication unit capable of transmitting and receiving an electric signal detected by the pressure detecting means and / or data processed by the control unit. For example, if the signal detected by the pressure detecting means is received by an external terminal, the external terminal can be used for recording, analysis, display by an application, and the like.

The shoe of the present invention is provided with a floating finger determining means capable of arranging a pressure detecting means at a predetermined position capable of determining whether or not the finger is a floating finger and notifying the user that the detected pressure has reached a threshold value or more. Therefore, it is possible to easily confirm whether or not the user himself is a floating finger. In addition, by simply informing the user of the condition of the toes during walking, it is necessary to make the user aware of walking using the toes, for example, the movement of the toes grasping the ground, and to prevent or improve the floating toes. Can be expected. In particular, when applied to children's shoes, it can be used to promote ideal foot development by training the toes with a sense of play.

It is a figure explaining the shoe of this invention. It is a figure explaining the floating finger determination means of this invention. It is the figure which compared the foot pressure measurement result in the upright posture of a standard person and a person with a floating finger. It is a figure which compared the average foot pressure measurement result at the time of walking of a standard person and a person with a floating finger. It is a figure which shows the foot pressure change of the toe part at the time of kicking by a standard person. It is a figure which shows the foot pressure change of the toe part at the time of kicking by a person with a floating finger. It is a figure explaining the method of determining whether or not it is a floating finger with respect to Embodiment 1. It is a figure explaining the method of determining whether or not it is a floating finger with respect to Embodiment 2.

The present invention is a shoe provided with a means for determining whether or not the finger is a floating finger, and is characterized in that the pressure in the area where the toes touch can be detected and the result can be notified to the user. Hereinafter, the present invention will be described with reference to the drawings, but the present invention is not limited to these embodiments.

As shown in FIGS. 1 and 2, the means for determining whether or not the finger is a floating finger (floating finger determining means) of the present invention includes a base member 2 provided with a pressure detecting means 3, a control unit 4, and a display unit 5. I have. In FIGS. 1 and 2, the base member 2 is attached to the shoe, and the control unit 4 and the display unit 5 are incorporated into the shoe as one device. The control unit 4 and the display unit 5 may be independent of each other, or if they are provided with communication means, they can be connected wirelessly and do not necessarily have to be incorporated in the shoes.

In the present invention, the floating finger is determined based on whether or not the foot pressure at a predetermined position reaches a threshold value or more. Based on the foot pressure measurement results shown in FIGS. 3 to 6, the predetermined position is a portion corresponding to the mother toe and a portion corresponding to one or two or more toes of any one of the 2nd to 5th toes. The pressure detecting means 3 is arranged.

Here, FIGS. 3 to 6 comparing the foot pressure measurement results of a person with a floating finger and a person (standard) who weighs 65 kg and does not have a floating finger will be described.
FIG. 3 is a diagram comparing the results of measuring the foot pressure in an upright posture with a foot pressure measuring device (manufactured by COMFORT LAB Co., Ltd., trade name “Foot Navi”). In the person with the floating finger on the right side of FIG. 3, it is shown that there is no pressure on the toes or the pressure is so weak that it cannot be detected.
In addition, FIG. 4 is a diagram comparing the results of measurement using a system (manufactured by Nitta Corporation, trade name "F-scan") that dynamically measures the foot pressure distribution during walking, and walks for 10 seconds. It is the average of the pressure peaks detected by each sensor in. The person with floating fingers on the right side of FIG. 4 shows that the pressure on the toes is weak even when walking. The white line in FIG. 4 indicates the locus of movement of the center of gravity, but in the case of a person with a floating finger, the white line stays at the forefoot and does not reach the toes, and the toes are not used during walking. I understand well. That is, the foot pressure of a person with floating fingers tends not to detect pressure on the toes including the hallux or is very weak in an upright posture, especially when walking.

As described above, in order to determine whether or not the finger is a floating finger, the pressure detecting means 3 may be arranged at a location corresponding to the mother toe and a location corresponding to one or two or more toes of any one of the 2nd to 5th toes. It is preferable to use two places, one is the mother toe and the other is the second and third toes.
Further, the pressure detecting means 3 may be provided at a position corresponding to the ball of the toe. Normally, when walking, the ball of the toe is always in contact with the ground. Therefore, depending on whether or not the ball of the toe is in contact with the ground, it is determined whether or not the user is walking normally, rather than walking in which it cannot be determined whether or not the finger is a floating finger such as walking on the toes, and it is more reliably determined whether or not the user is a floating finger. be able to.

Next, the threshold value will be described.
FIGS. 5 and 6 are diagrams comparing the changes in foot pressure at the toes of a person with a floating finger and a person without a floating finger (standard) at the time of kicking, respectively, from left to right when kicking (pressure of the forefoot). It shows the transition from the maximum time) to the end of kicking (before the pressure on the forefoot disappears). The table in the figure shows the maximum pressure (unit: kg / cm ² ) of each toe and ball during this period.
As shown in FIGS. 5 and 6, the toe peaks of both of them become smaller with the passage of time, but the person with the floating toes shown in FIG. 6 has the maximum pressure of each toe as compared with the person with the standard 1. It is as low as 0 kg / cm ^{2 or more.} From this result, it can be seen that the floating finger can be determined based on whether or not the foot pressure reaches the threshold value or higher.
Although it depends on the weight, for example, in the case of an adult, the pressure of the toes of a standard person in an upright posture is 0.5 kg / cm ² or more, and when walking, the pressure of the toes is 3 to 7 kg / cm ² , Other toes are about ² to 6 kg / cm 2. On the other hand, the pressure of the toes of a person with floating fingers in the upright posture is ^{less than 0.5 kg / cm 2} for all toes, ^{less than 3 kg / cm 2 for the} toes when walking, and 1 for the other toes. It is as low as less than .5 kg / cm ^2.

In the present invention, the threshold value may be appropriately set according to the weight of the user. For example, when walking is the judgment target, for a person weighing 65 kg, the threshold value of the toes during walking was set to 1.5 kg / cm ² from the results of FIGS. 3 to 6, and this value was exceeded. If it is, it is evaluated that the toes are usable, and if it does not exceed, it can be judged that it is a floating finger.
Moreover, the threshold value may be set in two steps or more. For example, if the first threshold value indicating the upright posture and the second threshold value indicating the walking time are used, it is possible to more reliably determine whether or not the finger is a floating finger, and the first and second threshold values are used. If the change of the display part is different, the change can be enjoyed while exercising the toes.

As a means for determining the threshold value, a method of measuring the weight of the user using a load sensor and reflecting the result, a method of inputting the weight to the control unit and automatically calculating the threshold value, etc. can be considered. Be done. Further, if there is a factor that affects the detected pressure, for example, the foot pressure is detected low when an insole having a cushioning property is used, the threshold value may be appropriately corrected.

As the pressure detecting means 3 of the present invention, for example, a general pressure sensor can be used, and in particular, a pressure-sensitive conductive rubber that converts pressure into an electronic signal and detects it, a membrane switch (physically contacting, and displaying at the same time). However, it is preferable in that the thickness can be reduced and it is easy to handle. If necessary, a power supply or a recording device may be provided.

In the pressure detecting means 3 of the present invention, the size required to detect the pressure of the toes is preferably 13 mm or more in the heel direction (longitudinal) and 11 mm or more in the width direction from the toe, and more preferably. The length is 24 mm or more and the width is 14 mm or more. If the length is less than 13 mm and the width is less than 11 mm, the position of the pressure detecting means 3 and the toes do not match due to individual differences such as the size of the foot and the type of toes (Greek type, Egyptian type, square type). It may not be possible to detect the pressure accurately.

The base member 2 of the present invention is for mounting the pressure detecting means 3 on the inner sole of the shoe, and may occupy at least the area in contact with the toes, occupy the forefoot, or occupy the entire foot. It should be. For example, it may be an insole or an insole that can be removed from the shoe.
A flexible material is preferable, and a material usually used for an insole or an insole can be applied.

As a method of arranging the pressure detecting means 3 on the base member 2, a method of attaching the pressure detecting means 3 to the front surface (the surface in contact with the sole of the foot) or the back surface (the surface in contact with the sole of the foot) of the base member 2 or a recess in the surface of the base member 2. A method of forming the pressure detecting means 3 and embedding the pressure detecting means 3 therein, a method of sandwiching the pressure detecting means 3 between the base members 2, and the like can be used. If necessary, a protective layer such as a tarpaulin may be provided to prevent the pressure detecting means 3 from water droplets and dust.
Further, the surface of the base member 2 may be formed with irregularities that guide the toes to the pressure detecting means 3 correctly.

The control unit 4 of the present invention has a function of transmitting an electric signal detected by the pressure detecting means 3, determining whether or not the finger is a floating finger, and sending the result to the display unit 5. As the control unit 4, for example, a microprocessor may be used. If necessary, a power supply, a storage device, and the like may be incorporated.

The display unit 5 of the present invention includes means 6 (hereinafter, referred to as notification means) for notifying the result sent from the control unit. The notification content of the display unit 5 may be changed depending on the degree of toe pressure detected by the pressure detecting means 3, and the pressure threshold value is set to two levels or more, and the display unit 5 is set accordingly. It is preferable to change the content of the notification.
For example, the pressure exerted by the toes on the ground surface during walking, especially when kicking, is greater than the pressure exerted by the toes in an upright posture on the ground surface. That is, when the pressure exceeds a certain value (threshold value), it means that the person can walk firmly using the toes, and if the notification content of the display unit 5 is changed at that time, the notification content is changed. You can be aware that your toes are being used.

As the notification means 6, for example, light, sound, vibration, an image, or the like can be used, and there is no particular limitation as long as it is possible to notify the user whether or not the finger is a floating finger. It is also possible to display with a dedicated application by using a mobile communication terminal or the like as the display unit 5.

For example, FIGS. 1 and 2 show that the display unit 5 uses a three-color LED light source (lights up in red, yellow, and blue from the tip of the toe) as the notification means 6, and the pressure detecting means 3a and 3b during walking. Lights blue when both of the pressures detected in are above the threshold, yellow when only one of them exceeds the threshold, and red when both do not exceed the threshold. Change the notification content like this.

In addition, how many steps are in the floating finger state after walking for a certain period of time, or the walking state is scored for each step and accumulated, and the result is displayed on the display unit 5. You may do it. If the result can be recorded, it is not necessary to always check the display part, it can be checked when time is available, and it is confirmed whether the floating finger is improved from the comprehensive evaluation for a certain period of time. It will be easier to do.

The floating finger determination means of the present invention may include a communication unit that can transmit and receive to the outside.
For example, a base member 2 provided with a pressure detecting means 3 capable of transmitting data may be attached to the inner bottom of the shoe, and an external terminal provided with a control unit 4 and a display unit 5 capable of transmitting and receiving the data may be used. Examples of the communication means include generally known wireless communication such as WiFi or Bluetooth (registered trademark). Further, as the external terminal, a mobile communication terminal such as a smartphone or a tablet can be used in addition to a personal computer. If a pre-installed application is used, a wide variety of notification means 6 can be provided. As described above, if the floating finger determination means is provided with a communication unit, control and display can be performed by a mobile communication terminal or the like, and the control unit 4 and the display unit 5 do not have to be provided on the shoes.

Hereinafter, embodiments of the present invention will be described, but the present invention is not limited thereto.
