  The present invention relates to a walking measurement sensor used for performing evaluation and analysis related to human walking.

  Conventionally, evaluation related to walking (walking evaluation) is sometimes performed when rehabilitation for walking disorders is performed. For walking evaluation, for example, as disclosed in Patent Document 1, a detection device including a plurality of load sensors distributed on an insole attached to a shoe worn by a subject (person who measures walking) is used. There is.

  Also, conventionally, data for walking evaluation may be collected by directly attaching a pressure sensor or an on / off switch to the subject's sole.

JP 2014-45885 A

  In the case of a configuration using insoles in which load sensors are dispersedly arranged as in Patent Document 1, it is necessary to prepare various types of insoles (detection devices) according to the size of shoes, which is disadvantageous in terms of cost. . Further, depending on the compatibility between the insole in which the load sensors are distributed and the shoes worn by the subject, the insole may slide in the shoes, making it difficult to perform normal walking.

  Further, in the configuration in which a pressure sensor or the like is directly attached to the sole, the subject needs to take off socks one by one, and preparation takes time. Moreover, since the cable connected to the pressure sensor is in the shoe, there is a concern that the subject may feel uncomfortable when walking.

  In addition, although this inventor examined sticking detection parts, such as a pressure sensor which makes it possible to detect grounding and takeoff of a subject's foot, directly to a shoe sole, in this case, there is a concern about breakage of a detection part. It was. In particular, it has been found that when the detection unit attached to the shoe sole is removed from the shoe sole, the detection unit is easily broken.

  In view of the above, an object of the present invention is to provide a walking measurement sensor that can be used without being influenced by the size of a subject's foot and hardly affects the walking. Another object of the present invention is to provide a walking measurement sensor that can be easily attached to and detached from footwear such as shoes and is not easily damaged.

  In order to achieve the above object, the walking measurement sensor of the present invention is a walking measurement sensor that is attached to a partial region of the bottom surface of footwear worn by a subject, and is a first protection that is attached to the bottom surface of the footwear. A configuration comprising: a plate; a detection unit capable of detecting ground contact and separation of the foot of the subject wearing the footwear; and a second protection plate sandwiching the detection unit together with the first protection plate (first Is configured).

  Since the walking measurement sensor of this configuration is affixed to the bottom of the footwear, it can be easily attached and detached. Moreover, since the walking measurement sensor of this configuration is attached to a partial region of the bottom surface of the footwear, it is difficult to adversely affect walking. Moreover, according to this structure, since the detection part is pinched | interposed with two protective plates, possibility that a detection part will be damaged during walk evaluation is low. Furthermore, according to this configuration, the walking measurement sensor is not directly attached to the detection unit, but is attached via the first protective plate. Less likely to break.

  It is preferable that the walking measurement sensor of the first configuration has a configuration (second configuration) further including a wall portion provided around the side surface of the detection unit. According to this configuration, since the side surface can be protected in addition to the upper and lower surfaces of the detection unit, the possibility that the detection unit is damaged can be further reduced. Moreover, according to this structure, a motion of a detection part can also be controlled by a wall part. The wall portion may surround the entire side surface of the detection unit, or may surround a part of the side surface.

  In the walking measurement sensor of the second configuration, the wall portion may have a configuration (third configuration) including an elastic member. According to this configuration, even when the first protection plate and the second protection plate are connected via the wall portion, the detection unit can easily detect the grounding and the grounding of the subject's foot. .

  In the walking measurement sensor having any one of the first to third configurations, it is preferable that an anti-slip portion is formed on the second protective plate (fourth configuration). According to this configuration, it is possible to avoid a situation in which the shoe sole or the like becomes slippery during walking by attaching the walking measurement sensor to the bottom surface of the footwear.

  In the walking measurement sensor having any one of the first to fourth configurations, at least the first protection plate of the first protection plate and the second protection plate is made of metal ( The fifth configuration is preferable. According to this configuration, it is possible to further reduce the possibility that the detection unit is damaged when the walking measurement sensor is peeled off from the bottom surface of the footwear.

  In the walking measurement sensor having any one of the first to fifth configurations, the second protection plate may be configured by a flexible member (sixth configuration). According to this configuration, since the second protection plate is bent, for example, even when a wall portion is provided between the first protection plate and the second protection plate, the detection unit can detect the foot of the subject. Can be reliably detected.

  In the walking measurement sensor of any one of the first to sixth configurations, a surface of the first protection plate facing the detection unit and a surface of the second protection plate facing the detection unit Of these, a configuration (seventh configuration) in which convex portions are formed on at least one of them may be employed. According to this configuration, even when a dead area is provided in the detection unit, the detection unit can accurately detect the contact and takeoff of the foot of the subject.

  ADVANTAGE OF THE INVENTION According to this invention, the sensor for walk measurement which can be used without being influenced by the size of a test subject's leg | foot and does not exert a bad influence on walking can be provided. Moreover, according to the present invention, it is possible to provide a walking measurement sensor that can be easily attached to and detached from footwear such as shoes and is not easily damaged.

<First Embodiment>

  FIG. 1 is a schematic plan view of a walking measurement sensor 1 according to the first embodiment of the present invention as viewed from above. FIG. 2 is a schematic cross-sectional view taken along the line AA in FIG. As shown in FIGS. 1 and 2, the walking measurement sensor 1 includes a detection unit 10, and a first protection plate 11 and a second protection plate 12 that sandwich the detection unit 10.

  The detection part 10 should just be what can detect the earthing | grounding (state which contacted the walking surface) and the takeoff (state which left | separated from the walking surface) of the footwear bottom, for example, can be comprised by a pressure sensor, an on-off switch, etc. When the detection unit 10 is configured by a pressure sensor, the type of the pressure sensor is not particularly limited, and may be any of a strain gauge resistance type, a semiconductor piezoresistive type, a capacitance type, a silicon resonant type, and the like. Also good.

  The first protective plate 11 attached to the bottom surface of the footwear with a double-sided tape may be any material that can prevent the detection unit 10 from being damaged, for example, during walking measurement or when the walking measurement sensor 1 is peeled off from the footwear. The first protective plate 11 can be composed of, for example, a metal plate or a highly rigid resin plate. The first protective plate 11 is preferably formed as thin as possible for the purpose of, for example, preventing a subject wearing a footwear (a person who measures walking) from feeling uncomfortable. When the first protective plate 11 is made of metal, the first protective plate 11 may be made of a thin plate made of, for example, iron, stainless steel, aluminum alloy or the like.

  The second protective plate 12 that forms a pair with the first protective plate 11 and sandwiches the detection unit 10 may be any member that can protect the detection unit 10 from damage during walking measurement, for example. Similarly to the first protective plate 11, the second protective plate 12 is preferably formed as thin as possible within a range that does not impair the function of breakage of the detection unit 10. The second protective plate 12 may be formed of a metal plate, for example, like the first protective plate 11. The second protective plate 12 may be made of the same material as the first protective plate 12, but may be made of a different material. The second protective plate 12 may be formed of a thin plate having a non-slip effect such as a rubber plate.

  The detection unit 10 has an upper surface fixed to the first protection plate 11 and a lower surface fixed to the second protection plate 12. The fixing method may be a method using an adhesive or, in some cases, a method using a fixing tool such as a screw. Thereby, the detection part 10, the 1st protection board 11, and the 2nd protection board 12 become united. A cable 13 for transmitting data to the data processing device (not shown) connected to the walking measurement sensor 1 extends from the detection unit 10. The cable 13 is drawn out of the sensor 1 from the gap between the first protective plate 11 and the second protective plate 12.

  In this embodiment, the data obtained by the detection unit 10 is transmitted to the data processing device by wire, but the data obtained by the detection unit 10 is wirelessly transmitted to the data processing device. Good.

  In the present embodiment, the detection unit 10, the first protection plate 11, and the second protection plate 12 are rectangular when viewed from above (when viewed along a direction perpendicular to the plate surface). However, this is only an example, and other shapes may be used. These may be, for example, circular, semicircular, crescent, etc. when viewed from above. In addition, the detection unit 10, the first protection plate 11, and the second protection plate 12 may have the same shape as each other, or may have different shapes. The first protection plate 11 and the second protection plate 12 may have a shape in which a part thereof protrudes to protect the cable 13.

  The first protective plate 11 and the second protective plate 12 are preferably provided so as to have the same size when viewed from above, but may be provided differently. However, the first protective plate 11 and the second protective plate 12 are preferably provided with a size larger than that of the detection unit 10 when viewed from above.

  FIG. 3 is a schematic diagram showing a usage example of the walking measurement sensor 1 according to the first embodiment of the present invention. As shown in FIG. 3, the walking measurement sensor 1 is bonded to a shoe sole 100 (an example of a bottom surface of footwear) using a double-sided tape. As can be seen from the above description, the upper surface of the first protective plate 11 is attached to the shoe sole 100.

  When the part to which the walking measurement sensor 1 is attached is grounded (attached to the ground or floor), the detection unit 10 is pressed. When the detection unit 10 is configured by a pressure sensor, for example, it can be determined that the shoe sole 100 is grounded when the detection unit 10 detects that a pressure of a predetermined value or more is applied. Further, when the detection unit 10 is configured by an on / off switch, for example, it can be determined that the shoe sole 100 is grounded when the on / off switch is turned on.

  Further, when the detection unit 10 is configured by a pressure sensor, for example, when the pressure detected by the detection unit 10 becomes smaller than a predetermined value, the shoe sole 100 is released (from the ground or floor surface). It can be judged that it was separated. When the detection unit 10 is configured by an on / off switch, for example, it can be determined that the shoe sole 100 has left the ground when the on / off switch is turned off.

  Note that the determination of the ground contact and takeoff of the shoe sole 100 is made by a data processing device (not shown) connected to the walking measurement sensor 1 by the cable 13.

  As shown in FIG. 3, by adopting a configuration in which the walking measurement sensor 1 is attached to the heel portion and the toe portion of the shoe sole 100, the stance phase in which the foot is in contact with the walking surface (the ground surface or the floor surface) It is possible to detect a swing period in which the foot is away from the walking surface. That is, by attaching the walking measurement sensor 1 to the shoe soles 100 of the left and right shoes as shown in FIG. 3, the walking cycle of the left and right feet can be detected, and the left / right balance during walking of the subject can be detected. For this reason, the walking measurement sensor 1 of the present embodiment is suitable for use in, for example, rehabilitation of a hemiplegic patient.

  The walking measurement sensor 1 according to the present embodiment can complete preparation for walking measurement and clean-up by attaching it to the sole 100 with a double-sided tape or removing it from the sole 100 without taking off the socks. For this reason, it is possible to shorten a preparation period for measurement and a clean-up period. Moreover, the sensor 1 for walk measurement of this embodiment is hard to damage the detection part 10 when peeling a sensor from the shoe sole 100 by the effect which provided the 1st protection board 11. FIG.

Further, when walking, due to the effect of providing the two protective plates 11 and 12, the detection unit 10 is hardly damaged. Moreover, since the two protective plates 11 and 12 are thinly provided, it is difficult for the subject to feel uncomfortable during walking, and it is easy to perform normal walking. Furthermore, the walking measurement sensor 1 is small and attached to the shoe sole 100 without being affected by the size of the subject's foot. For this reason, according to the configuration of the present embodiment, it is not necessary to prepare a plurality of types of sensors according to the size of the foot of the subject.
