Summary of the Invention

Problems to be Solved by the Invention

[0004] In Patent Document 1, as a method (structure) for attaching a communication device, sewing to a fabric such as clothing with a thread and attaching by fitting a back plate or a snap button have been proposed. By the way, for example, in a nursery school or the like where a monitoring system capable of grasping the whereabouts of preschool children is introduced, when attaching the above communication device to a large number of preschool children, sewing to a fabric such as clothing with a thread is difficult for attachment and detachment, and in the case of attachment by fitting a back plate or a snap button, prior preparations such as making a hole for passing a fitting pin through the fabric of the clothing are also required.

[0005] An object of the present invention is to provide a communication device that is easy to attach to and detach from an attachment target.

Means for Solving the Problems

[0006] The communication device according to the present invention comprises a main body (10), a communication unit (31), main body-side suction members (40, 41, 42), a cover (50), and cover-side suction members (70, 71, 72). The communication unit is provided on the main body. The main body-side suction members are provided on the main body. The cover is provided on one side of the main body. The cover-side suction members are provided on the cover and can be attracted to the main body-side suction members by magnetic attraction.

[0007] With the above configuration, for example, by placing the main unit on the surface side of a fabric such as clothing, and the cover on the back side of the fabric, and aligning the positions of the main unit-side suction member and the cover-side suction member, the communication device can be easily attached to the clothing by sandwiching the clothing between the main unit and the cover due to the magnetic attraction between the main unit-side suction member and the cover-side suction member. Furthermore, the communication device can be easily removed from the clothing simply by pulling the main unit and the cover apart against the magnetic attraction between the main unit-side suction member and the cover-side suction member.

Here, at least the communication unit 31 of the communication device 1 used as the "teacher's sensor device" has a wireless LAN module. On the other hand, the communication unit 31 of the communication device 1 used as the "children's sensor device" does not need to have a wireless LAN module as long as it can receive Wi-Fi signals (radio waves) transmitted from the "teacher's sensor device".

[0013] The main body-side suction member 40 is provided on the main body 10. The cover 50 is provided on one side of the main body 10. The cover-side suction member 72 is provided on the cover 50 and can be attracted to the main body-side suction member 40 by magnetic attraction.

[0014] The communication device 1 further includes a location information detection unit 32. The location information detection unit 32 is provided on the main body 10 and is capable of detecting the location information of the main body 10. The location information detection unit 32 has a GPS module that utilizes GPS (Global Positioning System), which is one of the GNSS (Global Navigation Satellite System), and is capable of detecting the location information of a child or teacher (communication device 1, main body 10) on Earth. Here, at least the communication device 1 used as a "sensor device for children" is equipped with a location information detection unit 32. On the other hand, the communication device 1 used as a "sensor device for teachers" does not need to be equipped with a location information detection unit 32.

[0015] The communication device 1 further comprises a battery 35 and a processing unit 30. The battery 35 is a rechargeable secondary battery, such as a lithium-ion secondary battery. The battery 35 can supply power to the communication unit 31, the location information detection unit 32, the processing unit 30, etc. The processing unit 30 is a computing device, such as a microcontroller, and can process signals (information) transmitted between the communication unit 31, the location information detection unit 32, the battery 35, etc.

[0016] The configuration of communication device 1 will be described in detail below. As shown in Figure 2, the main body 10 has a main body base 11, a main body projection 12, a suction member hole 13, etc. The main body base 11 has a first main body base 111 and a second main body base 112. The first main body base 111 is formed of, for example, resin, with one surface being a curved disc shape. The second main body base 112 is formed of, for example, resin, with one surface being a flat disc shape. The main body base 11 is constructed by joining the other surfaces of the first main body base 111 and the second main body base 112. A housing space 110 is formed between the first main body base 111 and the second main body base 112. The housing space 110 houses a part of the communication unit 31, a position information detection unit 32, a battery 35, a processing unit 30, etc.

[0017] The main body projection 12 is formed integrally with the main body base 11, for example, by resin. The main body projection 12 is formed to project from the side of the second main body base 112 opposite to the first main body base 111 to the side opposite to the first main body base 111. The main body projection 12 has a projection base 121 and an arc-shaped extension 122. The projection base 121 is formed in the shape of a rectangular plate, with the projection direction from the main body base 11 corresponding to the plate thickness direction. The arc-shaped extension 122 is formed to extend outward from the projection base 121 from the outer peripheral walls of two of the four sides of the projection base 121 that are along the longitudinal direction. An arc-shaped wall surface 123 is formed on the side of the arc-shaped extension 122 opposite to the projection base 121. The arc-shaped wall surface 123 is formed in a curved shape to follow a part of the circumferential direction of the virtual cylindrical surface VT1 (see Figure 2(A)).

[0018] The suction member hole portion 13 is formed to be recessed in a circular (cylindrical) shape from the surface of the second main body base portion 112 of the main body base portion 11 on the side opposite to the first main body base portion 111 toward the first main body base portion 111 side. Two suction member hole portions 13 are formed in the second main body base portion 112 so that their centers substantially coincide with the center of the virtual cylindrical surface VT1.

[0019] The main body 10 further has a charging portion 21, charging terminals 22, magnets 23, magnets 24, a SIM card cover 25, an LED indicator 26, a strap hole 27, a screw hole 28, etc. The charging portion 21 is formed near one of the two short sides of the protruding portion base 121 (see FIG. 2(A)). Four charging terminals 22 are provided in the charging portion 21 so as to be arranged in a row and are electrically connected to the battery 35 via the processing portion 30. Thereby, the battery 35 can be charged by supplying power from the charging terminals 22. The magnets 23 and magnets 24 are provided inside the charging portion 21 on both sides in the arrangement direction of the charging terminals 22 arranged in a row.

[0020] The SIM card cover 25 is formed, for example, in a rectangular plate shape from resin and is provided so as to close the concave card accommodation portion 251 formed at the center of the protruding portion base 121. A SIM card 311 that constitutes a part of the communication portion 31 is accommodated in the card accommodation portion 251.

[0021] As shown in FIG. 1, the LED indicator 26 is provided at the outer edge portion of the first main body base portion 111 and can indicate (notify) the charging status, operating status, etc. of the communication device 1 to the outside by lighting or blinking in red, green, blue, etc.

[0022] The strap hole 27 is formed to penetrate the first main body base portion 111 and the second main body base portion 112 in the plate thickness direction. A string-like member such as a strap can be attached to the strap hole 27.

[0023] The screw holes 28 are formed at four locations on the outer edge of the side of the second main body base 112 opposite to the first main body base 111. The screw holes 28 are provided with screws for joining the first main body base 111 and the second main body base 112.

[0024] The main body-side suction member 40 is a permanent magnet, such as a neodymium magnet, and is formed in a disc shape. The outer edges of both end faces of the main body-side suction member 40 are beveled into a curved shape. As shown in Figure 2, the main body-side suction member 40 is provided by fitting and / or bonding to the inner circumferential walls of the suction member holes 13 formed in two locations on the main body 10. A retaining portion 131 is formed in the suction member hole 13. The retaining portion 131 is formed in an annular shape so as to extend radially inward from the inner circumferential wall of the end of the suction member hole 13 opposite to the first main body base portion 111. The retaining portion 131 can prevent the main body-side suction member 40 from coming loose (falling out) from the suction member hole 13 by locking the outer edge (corner) of one end face of the main body-side suction member 40. For convenience, one of the two main body-side suction members 40 provided in the two suction member holes 13 will be referred to as the main body-side suction member 41, and the other as the main body-side suction member 42.

[0025] The cover 50 is made of, for example, resin and has a cover plate portion 51, a cover cylindrical portion 52, a cover lid portion 53, etc. The cover plate portion 51 is formed in the shape of a disc. The cover cylindrical portion 52 is formed integrally with the cover plate portion 51 so as to extend cylindrically from one surface of the cover plate portion 51. The space inside the cover cylindrical portion 52 is connected (opens) to the other surface of the cover plate portion 51. The cover lid portion 53 is formed in the shape of a disc and is provided so as to cover the surface of the cover plate portion 51 opposite to the cover cylindrical portion 52. The space inside the cover cylindrical portion 52 that opens to the other surface of the cover plate portion 51 is closed by the cover lid portion 53. The cover 50 is provided on the side of the second main body base portion 112 opposite to the first main body base portion 111. Two cover cylindrical portions 52 are formed on the cover 50 so that their centers substantially coincide with the center of the virtual cylindrical surface VT1 and the center of the suction member hole portion 13. A charging opening 61 is formed in the cover 50. The charging opening 61 is formed so as to penetrate the cover plate portion 51 and the cover lid portion 53 at a position corresponding to the charging section 21 of the main body 10.

[0026] The cover-side suction member 70 is a permanent magnet, such as a neodymium magnet, and is formed in a disc shape. The outer edges of both end faces of the cover-side suction member 70 are beveled into a curved shape. The cover-side suction member 70 is provided by fitting and / or bonding to the inner circumferential walls of the cover cylindrical portions 52 formed in two locations on the cover 50. The cover cylindrical portion 52 has a retaining portion 521. The retaining portion 521 is formed in an annular shape so as to extend radially inward from the inner circumferential wall of the end of the cover cylindrical portion 52 opposite to the cover plate portion 51. The retaining portion 521 can prevent the cover-side suction member 70 from coming off (falling out) of the cover cylindrical portion 52 by locking the outer edge (corner) of one end face of the cover-side suction member 70. The cover-side suction member 70 is inserted into the inside of the cover cylindrical portion 52 from the end (opening) on ​​the cover lid portion 53 side of the cover cylindrical portion 52 before the cover lid portion 53 is attached to the cover plate portion 51. For convenience, one of the two cover-side suction members 70 provided on the two cover cylinder portions 52 will be referred to as cover-side suction member 71, and the other as cover-side suction member 72.

[0027] The main body-side suction member 41 has its end face on the cover 50 side magnetized as the south pole, and its end face opposite the cover 50 magnetized as the north pole. The cover-side suction member 71 has its end face on the main body 10 side magnetized as the north pole, and its end face opposite the main body 10 magnetized as the south pole. The main body-side suction member 42 has its end face on the cover 50 side magnetized as the north pole, and its end face opposite the cover 50 magnetized as the south pole. The cover-side suction member 72 has its end face on the main body 10 side magnetized as the south pole, and its end face opposite the main body 10 magnetized as the north pole. Therefore, the main body-side suction member 41 and the cover-side suction member 71, and the main body-side suction member 42 and the cover-side suction member 72 can be attracted to each other by their magnetic attraction (see Figure 2(B)). By making the magnetic poles of the end faces of the main body-side suction member 41 and the main body-side suction member 42 on the cover 50 side different, it is possible to suppress the cover 50 from being attracted to the main body 10 in the wrong direction (rotational position).

[0028] By placing the main body 10 on the front side of the fabric of the garment 2 and the cover 50 on the back side of the fabric (see Figure 2(C)), and aligning the main body side suction member 40 and the cover side suction member 70, the communication device 1 can be easily attached to the garment 2 by sandwiching the garment 2 between the main body 10 and the cover side suction member 70 due to the magnetic attraction between them (see Figure 2(D)). When the garment 2 is sandwiched between the main body 10 and the cover 50, a part of the garment 2 is positioned in the arc-shaped space between the arc-shaped wall surface 123 and the outer peripheral wall of the cover cylinder portion 52 (see Figure 2(D)). This suppresses misalignment of the communication device 1 relative to the garment 2.

[0029] Next, we will explain how to attach the communication device 1 to the clothing 2. First, the main body 10 and the cover 50 are separated by resisting the magnetic attraction between the main body side suction member 40 and the cover side suction member 70 (see Figure 3(A)). Next, the main body 10 is placed on the front side of the fabric of the garment 2, and the cover 50 is placed on the back side of the fabric (see Figure 3(B)). Then, while aligning the positions of the main body side suction member 41 and the cover side suction member 71, and the positions of the main body side suction member 42 and the cover side suction member 72, the main body 10 and the cover 50 are brought closer together, and the garment 2 is sandwiched between the main body 10 and the cover 50 (see Figures 3(C) and (D)). At this time, the garment 2 is firmly sandwiched between the main body 10 and the cover 50 due to the magnetic attraction between the main body side suction member 40 and the cover side suction member 70.

[0030] Next, the charging of the communication device 1 will be described. In this embodiment, charging using the charging cable 80 and charging using the charging station 90 will be described. The following describes charging using the charging cable 80. As shown in Figure 4(A), the charging cable 80 has a cable section 801, a magnetic attraction terminal 81, charging terminals 82, magnets 83 and 84, etc. The cable section 801 is a conductor capable of supplying power. The magnetic attraction terminal 81 is provided at one end of the cable section 801. Four charging terminals 82 are provided on the magnetic attraction terminal 81 in a row and are electrically connected to the cable section 801. Magnets 83 and 84 are provided on the magnetic attraction terminal 81 on both sides in the direction in which the charging terminals 82 are arranged in a row.

[0031] The end faces of magnets 23 and 24, located on the charging section 21 of the main unit 10, opposite the main unit base 11, are magnetized to the south pole and north pole, respectively. The end faces of magnets 83 and 84, exposed from the magnetic attraction terminal 81 of the charging cable 80, are also magnetized to the north pole and south pole, respectively. Therefore, magnets 23 and 83, and magnets 24 and 84 can be attracted to each other by their magnetic attraction.

[0032] When the magnetic attraction terminal 81 is brought close to the charging section 21 of the main unit 10, the magnetic attraction between magnets 23 and 83, and magnets 24 and 84 causes the magnetic attraction terminal 81 to be attracted to the charging section 21 via the charging opening 61. As a result, the charging terminal 22 on the main unit 10 and the charging terminal 82 on the charging cable 80 are electrically connected. By making the magnetic poles of the end faces of magnets 83 and 84 exposed from the magnetic attraction terminal 81 different, it is possible to prevent the magnetic attraction terminal 81 from being attracted to the charging section 21 in the wrong direction.

[0033] The battery 35 of the communication device 1 can be charged by supplying power from the other end of the cable 801 while the magnetic attraction terminal 81 and the charging unit 21 are attracted to each other. As shown in Figure 4(B), the LED indicator light 26 lights up, for example, red, while the communication device 1 is being charged.

[0034] The following describes charging using the Charging Station 90. Japanese Patent Publication No. 2018-175489 discloses a communication device that can be charged by contactless power transmission. In a nursery school or similar setting where it is necessary to install communication devices on many children, as in this embodiment, charging each communication device one by one is time-consuming and inefficient.

[0035] The object of the present invention is to provide a charging station capable of efficiently charging multiple communication devices.

[0036] As shown in Figure 5(A), the charging station 90 includes a station body 91, a placement recess 92, a charging unit 93, charging terminals 94, etc. The station body 91 is formed in the shape of a rectangular plate, for example, from resin. The placement recess 92 is formed by recessing a circular (cylindrical) shape from one side (top surface) of the station body 91. The inner diameter of the placement recess 92 is set to be slightly larger than the outer diameter of the main body 10 and cover 50 of the communication device 1. In this embodiment, a total of 12 placement recesses 92 are formed, for example, three in the vertical direction and four in the horizontal direction of the station body 91. The charging unit 93 is provided so as to protrude from the bottom surface of the placement recess 92. The shape of the charging unit 93 corresponds to the shape of the charging opening 61 of the cover 50 of the communication device 1. Four charging terminals 94 are provided on the charging unit 93 in a row and are electrically connected to a power supply unit (not shown).

[0037] As shown in Figure 5(B), the communication device 1 can be charged by placing it in the placement recess 92 of the charging station 90. When the communication device 1 is placed in the placement recess 92, the charging unit 93 fits into the charging opening 61 of the cover 50, the charging terminal 94 of the charging station 90 and the charging terminal 22 of the communication device 1 are electrically connected, and charging begins. Figure 5(B) shows a state in which three communication devices 1 are being charged. In this embodiment, the charging station 90 can charge up to 12 communication devices 1 at once. In this way, the charging station 90 can efficiently charge multiple communication devices 1.

[0038] As described above, in the embodiment of "Disclosure 1," the communication unit 31 is provided on the main body 10. The main body-side suction member 40 is provided on the main body 10. The cover 50 is provided on one side of the main body 10. The cover-side suction member 72 is provided on the cover 50 and can be attracted to the main body-side suction member 40 by magnetic attraction.

[0039] With the above configuration, for example, by placing the main body 10 on the front side of a piece of fabric such as clothing 2, and the cover 50 on the back side of the fabric, and aligning the positions of the main body-side suction member 40 and the cover-side suction member 70, the communication device 1 can be easily attached to clothing 2 by sandwiching the clothing 2 between the main body 10 and the cover 50 due to the magnetic attraction between the main body-side suction member 40 and the cover-side suction member 70. Furthermore, the communication device 1 can be easily removed from clothing 2 simply by pulling the main body 10 and the cover 50 apart against the magnetic attraction between the main body-side suction member 40 and the cover-side suction member 70.

[0040] Furthermore, in the embodiment described in "Disclosure 2," at least one of the main body-side suction member 40 and the cover-side suction member 70 is a magnet. In this embodiment, both the main body-side suction member 40 and the cover-side suction member 70 are magnets 24. Therefore, the magnetic attraction force between the main body-side suction member 40 and the cover-side suction member 70 can be increased, allowing the communication device 1 to be firmly attached to clothing 2, etc.

[0041] Furthermore, in the embodiment described in "Disclosure 3," multiple suction members 40 are provided on the main body 10. Multiple suction members 70 are provided on the cover 50. Therefore, the communication device 1 can be firmly attached to clothing 2, etc.

[0042] Furthermore, in the embodiment described in "Disclosure 4," two suction members 40 on the main body side are provided on one surface of the main body 10, with the center in between. Therefore, the communication device 1 can be attached to clothing 2, etc., in a balanced and secure manner.

[0043] Furthermore, "Disclosure 5" This embodiment further includes a location information detection unit 32. The location information detection unit 32 is capable of detecting the location information of the main unit 10. Therefore, the communication device 1 can be used as a "sensor device for children" for determining (monitoring) the location of children in a monitoring system.

[0044] (Other embodiments) In the above-described embodiment, an example was shown in which the magnetic poles of the end faces on the cover 50 side of the two main body-side suction members 40 were different, and the magnetic poles of the end faces on the main body 10 side of the two cover-side suction members 70 were different. In contrast, in another embodiment, the magnetic poles of the end faces on the cover 50 side of the two main body-side suction members 40 may be the same, and the magnetic poles of the end faces on the main body 10 side of the two cover-side suction members 70 may be the same.

[0045] In other embodiments, the main body side suction member 40 and the cover side suction member 70 may be provided as one or three or more on the main body 10 and cover 50, respectively.

[0046] Furthermore, in the above-described embodiment, an example was shown in which both the main body-side adsorption member 40 and the cover-side adsorption member 70 are magnets. In contrast, in other embodiments, one of the main body-side adsorption member 40 and the cover-side adsorption member 70 may be formed from a magnet (hard magnetic material), and the other may be formed from a soft magnetic material such as iron that is attracted by the magnetic force of the magnet.

[0047] Furthermore, in the above-described embodiment, an example was shown in which the magnetic poles of the end faces of the two magnets (23, 24) provided on the charging section 21 of the main unit 10 are different, and the magnetic poles of the end faces of the two magnets (83, 84) provided on the magnetic attraction terminal 81 of the charging cable 80 are different. In contrast, in another embodiment, the magnetic poles of the end faces of the two magnets (23, 24) provided on the charging section 21 of the main unit 10 are the same, and the magnetic poles of the end faces of the two magnets (83, 84) provided on the magnetic attraction terminal 81 of the charging cable 80 are the same.

[0048] In another embodiment, a magnet (hard magnetic material) or a soft magnetic material such as iron that can be attracted to the magnets 23 and 24 provided on the charging section 21 of the main unit 10 may be provided on the charging section 93 of the charging station 90. In this case, the electrical connection between the charging terminal 94 of the charging station 90 and the charging terminal 22 of the communication device 1 can be stabilized, and charging from the charging station 90 to the communication device 1 can be stabilized.

[0049] In another embodiment, a magnet (hard magnetic material) or a soft magnetic material such as iron, which can be attracted to the cover-side adsorption member 70 provided on the cover 50, may be provided on the bottom surface of the arrangement recess 92 of the charging station 90. In this case as well, the electrical connection between the charging terminal 94 of the charging station 90 and the charging terminal 22 of the communication device 1 can be stabilized, and charging from the charging station 90 to the communication device 1 can be stabilized.

[0050] Furthermore, in other embodiments, the location information detection unit may not be included. In this case, the present invention can be applied to communication devices that do not need to acquire location information of the object to which it is attached, such as IC tags (RFID) used for inventory management of clothing, etc.

[0051] Thus, this disclosure is not limited to the embodiments described above, and can be implemented in various forms without departing from its essence. [Explanation of symbols]
