  In addition, as footwear 10 generally used in nursing homes and the like, as shown in FIG. 4 (b), there are many shoes 10 provided with a belt portion 10 a that fastens the ankles of the wearer with surface fasteners. And in such footwear 10, the root portion of the belt portion 10a and the fixing portion of the hook-and-loop fastener are thick and have a portion that is particularly small in deformation among the above portions with small deformation. Therefore, this portion is most preferable as the installation position of the planar coil 54. The number of planar coils 54 may be one, or may be provided at two of the above three places. Also, as shown in the present example, it may be provided in all places. Also, there is no particular limitation on the installation method of the flat coil 54, and it may be embedded on the surface side of the upper portion 52 and the strip portion 53, or may be sewn on the surface, and a thin layer pocket is provided on the surface You may install in that.

  The cable from the planar coil 54 passes through the insoles 50, 50 'and is connected to the circuit 56.

  Further, in the configuration having a plurality of planar coils 54, a control unit (not shown) of the circuit unit 56 detects an induced voltage generated in each planar coil 54 at the time of charging operation, and preferentially uses the planar coil 54 with high induced voltage for charging. You may do so. Alternatively, the control unit may detect the charge remaining amount of the rechargeable battery 32, and change the number of flat coils 54 to be used according to the charge remaining amount.

  Next, the configuration of the charging unit (the charging unit 70a of the first embodiment and the charging unit 70b of the second embodiment) constituting the present invention will be described. Although the charging unit 70 a of the first form and the charging unit 70 b of the second form shown here are suitable for the present invention, the present invention is not particularly limited to this, and Any shape may be used as long as charging can be performed by contact. Further, the charging unit 70a of the first embodiment and the charging unit 70b of the second embodiment can charge either insole unit 50, 50 '.

  First, the charging units 70a and 70b of the first embodiment and the second embodiment have the same configuration as the feeding coil 74 for charging the rechargeable battery 32 by electromagnetic induction through the planar coil 54, the power from the commercial power source etc. A power supply unit 78 that supplies a predetermined high frequency voltage to the feed coil 74 and a charge control unit 76 that controls the operation of the feed coil 74 are included.

Further, as shown in FIG. 7, the charging portion 70 b of the second embodiment has a holder portion 73 into which the upper portion of the footwear 10 inserted with the insole portions 50 and 50 ′ is inserted. The feed coil 74 is fixed at a predetermined position of When the footwear 10 is inserted into an appropriate position of the shoe keeper 72 or the holder 73, the flat coil 54 on the side of the insole 50, 50 ′ when the footwear 10 is inserted into the proper position. And a position substantially opposite to. That is, when the planar coil 54 is present at a position where the metatarsal bone or the scaloid bone of a person's thumb is located, on the surface side of the shoe keeper portion 72 substantially opposite to this position, or on the inner surface side of the holder portion 73 When feed coil 74 is provided and planar coil 54 is present at a position where the metatarsal bone of a human finger is located, the surface side of shoe keeper 72 or a position of holder 73 substantially opposite to this position. A feed coil 74 is provided on the inner side. Furthermore, when the planar coil 54 is present on the upper side of the upper portion 52, the feed coil 74 is provided on the surface side of the shoe keeper portion 72 or on the inner surface side of the holder portion 73 substantially opposite to this position.

  Although the charging unit 70a of the first embodiment may be of a horizontal type, as shown in FIG. 6, the tip end of the shoe keeper unit 72 is directed upward to form a pair, and the longitudinal direction and the lateral direction are also possible. It is preferable that a plurality of the shoe racks are vertically arranged by arranging them in the vertical and horizontal directions or the like. In addition, although it is preferable to install the charging unit 70b of the second embodiment in a shoebox or shoe holder as a horizontal installation type, the tip end side of the holder unit 73 is directed downward and the two are paired. A plurality of shoes racks may be vertically arranged by arranging them in the direction and in the vertical and horizontal directions.

  Next, an example of the electronic device 30 installed in the footwear 10 and the insoles 50, 50 'will be described. In addition, the electronic device 30 shown below is an example, It is not limited to this, It is an apparatus which acquires and records or transmits a wearer's positional information, Well-known sensors, such as a reaction force sensor, an accelerometer, and a gyro Equipment that acquires and records or transmits walking information such as the number of steps, walking distance, fatigue, and wandering state of the wearer, and equipment that acquires and records biological information of the wearer, such as thermometers, sweat meters, and pulsimeters, etc. It may be anything. Further, when the electronic device 30 is separate from the insole portion 50, it is preferable to use the electronic device 30 which is detachable from the footwear 10 as in the insole portion 50. Although the position at which the electronic device 30 is fixed to the footwear 10 or the like is not particularly limited, when the belt 10 a is present in the footwear 10, as shown in FIG. 4B, the belt 10 a is provided. Is preferred.

  Next, the operation of an example of the electronic device 30 will be briefly described. The electronic device 30 illustrated here is installed in, for example, the footwear 10 of a wearer such as a patient with dementia, and transmits the position information of the wearer to a receiver (portable terminal such as a smartphone) carried by a nearby assistant. For example, a position information acquisition unit that receives signals from GPS satellites and acquires its own position information, a long-distance communication unit that transmits and receives information using a commercial wireless data communication network, and Zigbee And a near field communication unit that transmits and receives information using a near field wireless system such as (registered trademark), Bluetooth (registered trademark), BLE (Bluetooth (registered trademark) Low Energy), or the like. Then, the transmission of the position information is performed at regular intervals using the short distance communication unit which consumes less power in normal times. Further, for example, when the wearer moves out of the short distance wireless area by leaving the assistant, etc., and the receiving apparatus can not receive the position information, the receiving apparatus warns the assistant. The assistant receives a warning from the receiver and searches for the wearer based on the last position information received. Then, when the assistant comes within the range of the short distance wireless of the electronic device 30, the receiving device receives the position information from the electronic device 30 and specifies the position of the wearer, whereby the assistant protects the wearer. be able to. Also, if the search for the wearer is difficult, the assistant operates the receiver to transmit a position information transmission request using the commercial wireless data communication network to the electronic device 30. In response to the position information transmission request, the electronic device 30 transmits the position information by the commercial wireless data communication network using the long distance communication unit. As a result, the reception device of the assistant receives the position information from the electronic device 30 and specifies the position of the wearer, whereby the assistant can protect the wearer. As described above, only when the electronic device 30 receives the position information transmission request from the receiving device, the electronic device 30 transmits the position information using the commercial wireless data communication network which consumes a large amount of power. For this reason, the amount of power consumption is small and the long-time use becomes possible.

  Next, the operation and usage of the wearable device according to the present invention will be described. First, the insoles 50, 50 ′ are inserted into the inside of the footwear 10. At this time, the strip 53 is folded back to the outer surface of the footwear 10 in the second embodiment of the insole 50 ′. When the electronic device 30 is separate, the output line 58 extending from the insoles 50 and 50 'is connected to the electronic device 30.

  Next, the footwear 10 into which the insoles 50 and 50 'are inserted is inserted into the shooter unit 72 of the charging unit 70a of the first embodiment. Or it inserts in the holder part 73 of the charge part 70b of a 2nd form. At this time, as shown in FIG. 2C, a well-known belt member 11 may be wound around the outer surface of the insole portion 50 'so as to prevent curling of the folded strip portion 53. As a result, the planar coil 54 of the insole portion 50, 50 'and the feeding coil 74 of the charging portion 70a, 70b substantially face each other. Then, the power supply unit 48 of the charging units 70a and 70b sets the commercial power supply to a predetermined high frequency voltage of 100 kHz, for example, and applies the voltage to the feeding coil 74 via the charge control unit 76. Thereby, from the feeding coil 74, the magnetic field according to the direction of the high frequency voltage is alternately generated. Then, in the planar coil 54 facing the feeding coil 74, an induced voltage is generated by the electromagnetic induction of the feeding coil 74, and an induced current flows.

  When an induced voltage is generated in the planar coil 54, the switching unit 56b detects this and opens the connection between the rechargeable battery 32 and the output line 58 to stop the power supply to the electronic device 30, and the rechargeable battery 32 and the charging unit 56a. Close the connection with As a result, the induced current generated in the planar coil 54 is rectified and smoothed by the charging unit 56 a, and becomes, for example, a predetermined DC power of 4.5 V, and is output to the rechargeable battery 32. Thereby, charging of the rechargeable battery 32 is performed. At this time, the charge control unit 76 may notify that the footwear 10 (insoles 50, 50 ') is being charged by turning on the charge indicator or the like. Further, when charging of the rechargeable battery 32 is completed, the color of the charging indicator or the light emitting operation may be changed to notify the completion of charging of the footwear 10 (insoles 50, 50 ').

  Next, the footwear 10 is removed from the charging units 70a and 70b and worn on the foot of the user. At this time, the switching unit 56b detects that the induced voltage of the planar coil 54 has disappeared, and opens the connection between the rechargeable battery 32 and the charging unit 56a, and closes the connection between the rechargeable battery 32 and the output line 58. Thereby, the power from the rechargeable battery 32 is supplied to the electronic device 30 to perform a predetermined operation.

  Next, the wearer wears the footwear 10 and performs activities. At this time, since the planar coil 54 is installed at a portion where there is relatively little deformation as described above, the deformation at the time of use hardly affects it. Further, since the rechargeable battery 32 and the circuit unit 56 (and the electronic device 30) are installed at the arched portions of the insoles 50 and 50 ', the effects of shock and load during use can be suppressed to a low level.

  When the footwear 10 is to be replaced due to staining or the like, the insoles 50, 50 'are removed from the old footwear 10 and mounted on the new footwear 10. As a result, when the electronic device 30 is separate from the insoles 50 and 50 ', the power source (the rechargeable battery 32 and the circuit portion 56) of the electronic device 30 can be easily transferred to the existing footwear 10. Further, in the configuration in which the electronic device 30 is built in the insoles 50, 50 ', the main body of the wearable device can be easily transferred to the existing footwear 10.

  As described above, the wearable device according to the present invention provides the flat coil 54 for charging and the rechargeable battery 32 in the insoles 50 and 50 ′ of the footwear 10. Therefore, when the electronic device 30 is separate from the insoles 50, 50 ', the power supply of the electronic device 30 can be easily transferred to the existing footwear 10 by moving the insoles 50, 50'. It becomes possible. Further, in the configuration in which the electronic device 30 is built in the insoles 50, 50 ', the main body of the wearable device can be easily transferred to the existing footwear 10. As a result, the user can use inexpensive commercial footwear 10, and the economic burden can be reduced. Further, since the manufacturer side only needs to manufacture the insoles 50, 50 ', it is not necessary to arrange the product lineup of the footwear 10, and the manufacturing cost can be reduced. Furthermore, in the configuration in which the electronic device 30 is separate from the insole portions 50, 50 ', the insole portions 50, 50' can be used as power sources of various electronic devices 30 worn by the user.

  The insoles 50 and 50 'each include the upper 52 that covers the instep from the fingertips of the foot, and the flat coil 54 is provided on the surface side of the upper 52 in the first embodiment of the insole 50. Further, in the second embodiment of the insole portion 50 ′, a strip 53 is provided, and the flat coil 54 is provided on the strip 53. And since the planar coil 54 is provided in the part with little deformation | transformation at the time of walk etc., a deformation | transformation to the planar coil 54 at the time of use hardly arises. The charging through the planar coil 54 is performed via the shoe keeper portion 72 inserted into the upper portion 52 or the holder portion 73 into which the upper portion 52 is inserted. Here, when the planar coil 54 is provided on the bottom surface of the insole portion, the outer sole of the footwear 10 can not be disposed close to the planar coil 54 and the feeding coil 74 due to its thickness, and charging efficiency is poor. However, by providing the planar coil 54 in the upper portion 52 or the strip portion 53 of the insole portion 50, 50 ′, the feed coil 74 provided in the shoe keeper 72 or the holder 73 can be disposed close to the planar coil 54. Thereby, charging of the rechargeable battery 32 can be performed with sufficient efficiency.
