In this way, the IC tag 30 is disposed inside the head 12 of the bolt 11.

  The tagged bolt 10 shown in FIG. 1 is formed by the above procedure. In this bolt 10 with a tag, since the lid member 40 fitted into the hollow portion 26 has a restoring force, the restoring force from the lid member 40 always acts on the peripheral side surface 26b forming the hollow portion 26. It will be. Therefore, due to the presence of the cutout portion 44, the lid member 40 is more firmly fitted into the hollow portion 26. Further, since the lid member 40 is fitted into the hollow portion 26 so that the notch 44 is located at the same position in the circumferential direction as the slit 29, the eddy current generated in the entire head 12 of the bolt 11 is more effectively prevented. Can be blocked. Further, when the bolt 10 with a tag is fitted in a predetermined place, it is fitted between a head 12 and an installation surface via a resin washer. By installing the tag-attached bolt 10 through the resin washer in this way, it is possible to prevent a flash from being generated between the slits 29 due to friction between the lower flat surface 22a of the main body head 22 and the installation surface. . In addition, since an eddy current will generate | occur | produce in the circumferential direction of the head 12 when a flash | burst arises, this eddy current can be prevented through a resin washer.

  Next, the reading / writing of the data with respect to the bolt 10 with a tag is demonstrated.

Accordingly, the reader is brought close to the head 12 of the bolt 10 with the tag fitted in the land or the like, and a signal by radio waves or electromagnetic waves is transmitted from the reader to the IC tag 30 serving as a wireless IC tag. Reading and writing are performed. As a communication method between the IC tag 30 and the reader, a magnetic coupling method or Bluetooth is adopted. Further, communication between the IC tag 30 and the reader may be performed by infrared rays.

  In the bolt 10 with a tag configured as described above, the IC tag 30 is held by the lid member 40, so that the IC tag 30 can be attached to the hollow portion 26 by fitting the lid member 40 to the hollow portion 26. The IC tag 30 can be disposed on the head portion 12 of the bolt 11 by being disposed inside the hollow portion 26 and the small space portion 28. Accordingly, when the bolt 10 with a tag is fitted in a predetermined place, the head 12 of the bolt 11 protrudes from the installation surface, so that the IC tag 30 is arranged not near the installation surface or under the ground but near the installation surface such as the ground. Will be. Therefore, when the reader is brought close to the head 12, the distance between the reader and the IC tag 30 is reduced, and radio waves emitted from the reader are reliably transmitted to the IC tag 30, so that the communication between the reader and the IC tag 30 is performed accurately. It will be. Further, when the lid member 40 is formed of a non-conductive material such as a resin material, the non-conductive material transmits radio waves, so that communication between the reader and the IC tag 30 is further reliably performed.

  Moreover, in the bolt 10 with a tag, since the cover member 40 is a cylindrical body, the cover member 40 can be easily fitted into the hollow portion. Further, since the IC tag mounting portion 43 is provided on the opening plane 41a facing the opening 41 on the other end side, the IC tag 30 can be held at a position closer to the other end side in the lid member 40. It will be possible. Therefore, when the lid member 40 is fitted into the hollow portion 26 and the data of the IC tag 30 is read / written by the reader, the distance between the reader and the IC tag 30 is reduced, and communication between the reader and the IC tag 30 is performed. Will be performed more accurately.

  Moreover, in the bolt 10 with a tag, the head 12 is comprised from the main body head 22 used as the large diameter part integrated with the screw part 24, and the small diameter cover member 40 put into this main body head 22. FIG. Therefore, the tag-attached bolt 10 can be completed by a simple operation of holding the IC tag 30 on the lid member 40 and inserting the lid member 40 into the main body head 22.

  Moreover, in the bolt 10 with a tag, the slit 29 and the notch part 44 along the axial direction of the volt | bolt 11 are provided in the same position on the side surface of the main body head part 22 and the cover member 40 in the circumferential direction. Therefore, when the lid member 40 is contracted from both sides sandwiching the notch 44 serving as a slit, the lid member 40 is easily fitted into the hollow portion 26 and the lid member 40 has a restoring force. Become. Therefore, when the lid member 40 is fitted to the hollow portion 26, a restoring force always acts on the peripheral side surface 26b surrounding the hollow portion 26, and the fitting strength of the lid member 40 to the hollow portion 26 is improved. . Further, the vortex generated along the circumferential direction of the head 12 of the bolt 11 by setting the slit 29 provided in the main body head 22 and the notch 44 provided in the lid member 40 to the same position in the circumferential direction. The current can be cut off or reduced efficiently, the radio wave transmitted from the reader is prevented from being weakened by the eddy current, and communication between the IC tag 30 and the reader is performed accurately.

  Next, a tagged bolt 60 according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a perspective view showing a bolt 60 with a tag according to the second embodiment of the present invention. FIG. 6 is an exploded perspective view showing a bolt 60 with a tag according to the second embodiment of the present invention, and FIG. 7 is a side sectional view of the bolt body 20 of FIG. FIG. 8 is a side sectional view showing a state where the stick-like IC tag 30 is attached to the lid member 70. In the following description, in FIGS. 5 to 8, one end side indicates the lower side and the other end side indicates the upper side. The same members and the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted or simplified.

  As shown in FIGS. 5 and 6, the tagged bolt 60 mainly includes a bolt 61 and an IC tag 30. The bolt 61 is mainly composed of a metal bolt main body 20 and a lid member 70 that is a member constituting the head 62 of the bolt 60 with a tag and has a function of holding the IC tag 30. As in the case of the first embodiment, the tagged bolt 60 is provided, for example, in such a manner that a screw hole is provided in a target place or facility such as a manhole or a wall and screwed into the screw hole. The

  The bolt main body 20 includes a main body head portion 22 and a screw portion 24 as in the case of the first embodiment. The screw portion 24 is formed to protrude from the center of the lower flat surface 22a of the main body head portion 22 to one end side. The outer shape of the main body head portion 22 is a hexagonal column, and a cylindrical hollow portion 26 is formed at the center of the upper plane 22 b of the main body head portion 22. Further, a cylindrical small space portion 28 is formed from the center of the hollow portion 26 along the axial direction of the screw portion 24 and toward one end side. A screw groove 24 a is formed on the peripheral side surface of the screw portion 24.

  A slit 29 along the axial direction of the bolt main body 20 is formed on the side surface 22c of the main body head portion 22 as in the case of the first embodiment. In the slit 29, a portion extending from the upper plane 22 b of the slit 29 to the bottom surface 26 a forming the hollow portion 26 penetrates from the side surface 22 c to the hollow portion 26. Further, the portion of the slit 29 extending from the bottom surface 26 a to the lower bottom surface 22 a is cut out from the side surface 22 c to the peripheral side surface 26 b forming the hollow portion 26.

  The IC tag 30 is a stick-like IC tag having a circular cross section, and is an RFID tag having a writable and nonvolatile semiconductor memory. The IC tag 30 is attached to a lid member 70 which will be described later, and is disposed inside the small space portion 28.

  The lid member 70 is a metallic member made of aluminum, stainless steel, or brass, and is integrated with the main body head portion 22 by being fitted into the main body head portion 22 of the bolt main body 20 to constitute the head portion 62 of the bolt 61. It becomes. The lid member 70 is a cylindrical body having a through hole 72 having a circular cross section at the center, and the IC tag 30 is fitted into the through hole 72. As shown in FIG. 8, the IC tag 30 is held by the lid member 70 so as to be fitted into the through hole 72, and the IC tag 30 protrudes from one end side of the lid member 70. The IC tag 30 is fitted into the through hole 72 so that the other end of the IC tag 30 is located on the same plane as the flat surface 70 a on the other end side of the lid member 70. Then, with the IC tag 30 fitted in the through-hole 72, the other end of the IC tag 30 is sealed 73 with resin or the like.

  FIG. 5 shows a state after the lid member 70 holding the IC tag 30 is fitted into the hollow portion 26 of the main body head portion 22. Since the IC tag 30 is held by the lid member 70, the front end portion of the IC tag 30 is disposed inside the small space portion 28 as the lid member 70 is fitted into the hollow portion 26. Therefore, the IC tag 30 is disposed on the head 62 of the bolt 61.

  Next, a method for assembling the tagged bolt 60 shown in FIG. 5 will be described.

  First, the other end of the IC tag 30 is fitted into the through hole 72 of the lid member 70. As a result, the IC tag 30 is held by the lid member 70, and the IC tag 30 is integrated with the lid member 70. Next, a sealing 73 is applied to the surface of the integrated IC tag 30 and the lid member 70 on the other end side of the IC tag 30. Next, the lid member 70 is fitted into the hollow portion 26 formed in the head portion 62 of the bolt 61. At this time, one end of the IC tag 30 is inserted into the small space 28 simultaneously with the fitting. Since the IC tag 30 and the lid member 70 are integrated, the tip portion of the IC tag 30 is disposed in the small space 28. In this way, the IC tag 30 is disposed inside the head 62. The tagged bolt 60 shown in FIG. 5 is formed by the above procedure. Further, when the bolt 60 with a tag is fitted into a predetermined place, it is fitted through a resin washer between the head 62 and the installation surface as in the case of the first embodiment. . Moreover, since reading and writing of data with respect to the bolt 60 with the tag is the same as in the case of the first embodiment, the description thereof is omitted.

  In the bolt 60 with a tag configured as described above, since the IC tag 30 is held by the lid member 70, the IC tag 30 is connected to the lid member 70 by fitting the lid member 70 into the hollow portion 26. The IC tag 30 can be disposed on the head 62 because the IC tag 30 is disposed inside the small space portion 28. Therefore, when the bolt 60 with a tag is fitted in a predetermined place such as the ground, the head 62 of the bolt 61 protrudes from the installation surface such as the ground, so the IC tag 30 is not under the ground but near the installation surface such as the ground. Will be placed. Therefore, when the reader is brought close to the head 62, the distance between the reader and the IC tag 30 is reduced, and radio waves emitted from the reader are reliably transmitted to the IC tag 30, so that the communication between the reader and the IC tag 30 is performed accurately. It will be. Further, when the lid member 70 is formed of a non-conductive material such as a resin material, the non-conductive material transmits radio waves, so that the communication between the reader and the IC tag 30 is reliably performed.

  Moreover, in the bolt 60 with a tag, since the cover member 70 is a cylindrical body, the cover member 70 can be easily fitted into the hollow portion 26. Further, by fitting the IC tag 30 into the through hole 72, the IC tag 30 is placed on the lid member 70 so that the other end of the IC tag 30 is flush with the plane 70 a on the other end side of the lid member 70. It will be possible to hold. Therefore, when the lid member 70 is fitted into the hollow portion 26 and the data of the IC tag 30 is read / written by the reader, the distance between the reader and the IC tag 30 is most shortened. Communication is performed accurately.

  Moreover, in the bolt 60 with a tag, the slit 29 along the axial direction of the volt | bolt 61 is provided in the side surface of the head 62 (specifically, the side surface of the main body head 22). Therefore, the eddy current generated along the circumferential direction of the head 62 can be reduced, the radio wave transmitted from the reader is prevented from being significantly weakened by the eddy current, and the communication between the IC tag 30 and the reader has been performed so far. This will be done accurately. Note that when the lid member 70 is made of a material that does not generate eddy current, such as resin, instead of being made of metal, the slit 29 is very advantageous for accurate communication. On the other hand, when the IC tag 30 is strong, the slit 29 may not be provided because the IC tag 30 is exposed directly from the head 62 or exposed through the shield 73.

  Moreover, in the bolt 60 with a tag, the sealing 73 is given to the surface of the other end side of the IC tag 30 among the integrated IC tag 30 and the lid member 70. Therefore, it is possible to prevent the IC tag 30 from being damaged by exposing the other end of the IC tag 30.

FIG. 9 is a perspective view showing a bolt 80 with a tag according to the third embodiment of the present invention. FIG. 10 is an exploded perspective view showing a tagged bolt 80 according to the third embodiment of the present invention, and FIG. 11 is a side sectional view of the bolt main body 85 of FIG. FIG. 12 is a side sectional view showing a state in which the disc-shaped IC tag 90 is fitted to the lid member 95. In the following description, in FIGS. 9 to 12, one end side indicates the lower side and the other end side indicates the upper side. The same members and the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted or simplified.

  As shown in FIGS. 9 and 10, the tagged bolt 80 mainly includes a bolt 81 and an IC tag 90. The bolt 81 is mainly composed of a metal bolt body 85 and a lid member 95 that is a member constituting the head portion 82 of the bolt 81 and has a function of holding the IC tag 90. As in the case of the first embodiment, the tagged bolt 80 is provided, for example, in such a manner that a screw hole is provided in a target place such as a manhole or a wall and screwed into the screw hole. .

  As shown in FIGS. 9 to 11, the bolt main body 85 includes a main body head portion 86 and a screw portion 87. The screw portion 87 is formed so as to protrude from the center of the lower flat surface 86 a of the main body head portion 86 to one end side. The outer shape of the main body head 86 is a hexagonal column, and a cylindrical hollow portion 26 is formed in the center of the upper plane 86b of the main body head 86 so as to open. A screw groove 87 a is formed on the peripheral side surface of the screw portion 87.

  As in the case of the first embodiment, a slit 89 is formed on the side face 86c of the main body head 86 along the axial direction of the bolt main body 85 from the upper plane 86b to the bottom face 26a. That is, a portion extending from the upper plane 86 b of the slit 89 to the bottom surface 26 a forming the hollow portion 26 penetrates from the side surface 86 c to the hollow portion 26. The slit 89 is a portion extending from the bottom surface 26a to the lower bottom surface 86a and is not cut out from the side surface 86c to the portion extending from the peripheral side surface 26b forming the hollow portion 26, but may be cut out. .

  The IC tag 90 is a disc-shaped IC tag, and is an RFID tag having a writable and nonvolatile semiconductor memory. The IC tag 90 is fitted into a lid member 95 described later, and is arranged inside the hollow portion 26.

  The lid member 95 is a metal member made of aluminum, stainless steel, or brass. As shown in FIG. 12, the lid member 95 has a cylindrical opening 96 at the center on one end side and is closed on the other end side. It has become. The IC tag 90 is attached to the opening plane 96a having a circular cross section that forms the internal space 97 of the opening 96. Therefore, the IC tag 90 is held in the internal space 97 of the lid member 90.

  Further, in the cylindrical portion 95a of the opening 96 provided in the lid member 90, as shown in FIG. 10, three slits 99 are provided at intervals of 120 degrees in a direction perpendicular to the circumferential direction. The three slits 99 are provided in the cylindrical portion 95a surrounding the internal space 97 of the lid member 95, and do not reach the bottom surface portion 95b. However, a part of the bottom surface portion 95b may be cut out, or may be cut out to substantially the center of the lid member 95 as in the first embodiment. Further, only one slit 99 may be provided, two may be provided at intervals of 180 degrees, or four may be provided at intervals of 90 degrees.

  FIG. 9 shows a state after the lid member 95 holding the IC tag 90 is fitted into the hollow portion 26 of the main body head portion 86. In the tagged bolt 80, the lid member 95 is formed in the hollow portion 26 so that one of the three slits 99 provided in the lid member 95 is in the same position in the circumferential direction as the slit 89 formed in the main body head 86. It is mated. Further, since the IC tag 90 is fitted into the opening 96 of the lid member 95, the IC tag 90 is disposed in the hollow portion 26 as the lid member 95 is fitted into the hollow portion 26. Therefore, the IC tag 90 is disposed on the head 82 of the bolt 81.

  Next, a method for assembling the tagged bolt 80 shown in FIG. 9 will be described.

  First, the IC tag 90 is fitted into the opening 96 of the lid member 95. Thus, the IC tag 90 is held by the lid member 95 and is integrated with the lid member 95. Next, the cylindrical member 95 a sandwiching the slit 99 is pressed to shrink the lid member 95. The shrunken lid member 95 has a restoring force to restore the original state. Then, the contracted lid member 95 is fitted into the hollow portion 26 formed in the main body head 86 of the bolt main body 85. Since the IC tag 90 and the lid member 95 are integrated, the IC tag 90 is disposed in the hollow portion 26. Further, at the time of fitting, one of the slits 99 is positioned at the same position in the circumferential direction as the slit 89 formed in the main body head 86. In this way, the IC tag 90 is disposed inside the head 82.

  The tagged bolt 80 shown in FIG. 9 is formed by the above procedure. In this tagged bolt 80, since the lid member 95 fitted in the hollow portion 26 has a restoring force, the restoring force from the lid member 95 always acts on the peripheral side surface 26b forming the hollow portion 26. It will be. Accordingly, due to the presence of the slit 99, the lid member 95 is more firmly fitted into the hollow portion 26. In addition, when the bolt 80 with a tag is fitted into a predetermined place, it is fitted through a resin washer between the head 82 and the installation surface as in the case of the first embodiment. . Further, since reading and writing of data with respect to the tagged bolt 80 is the same as in the case of the first embodiment, description thereof is omitted.

  In the bolt 80 with a tag configured as described above, since the IC tag 90 is held by the lid member 95, the IC tag 90 can be attached to the bolt 81 by fitting the lid member 95 into the hollow portion 26. It can be arranged on the head 82. Therefore, when the bolt 80 with a tag is fitted in a predetermined place such as the ground, the head 82 protrudes from the ground or the like, or is located near the installation surface. Therefore, the IC tag 90 is not inside the ground or the like. It will be placed on the ground or near the installation surface. Therefore, when the reader is brought close to the head 82, the distance between the reader and the IC tag 90 is reduced, and radio waves emitted from the reader are reliably transmitted to the IC tag 90, so that the communication between the reader and the IC tag 90 is performed accurately. It will be. Further, when the lid member 95 is formed of a non-conductive material such as a resin material, the non-conductive material transmits radio waves, so that the communication between the reader and the IC tag 90 is reliably performed.

  Moreover, in the bolt 80 with a tag, since the cover member 95 is a cylindrical body, the IC tag 90 can be easily fitted into the hollow portion 26. Further, since the IC tag 90 is held by the lid member 95 so as to be in close contact with the opening plane 96a, the IC tag 90 is held at a position closer to the other end side in the head 82, that is, a position closer to the outside. Will be. Therefore, when reading / writing data of the IC tag 90 with a reader, the distance between the reader and the IC tag 90 becomes short, and communication between the reader and the IC tag 90 is performed accurately.

  Moreover, in the bolt 80 with a tag, the head 82 is comprised from the large diameter part integral with the screw part 87, and the small diameter cover member 95 put in the main body head 86 used as this large diameter part. Therefore, the IC tag 90 can be placed on the head 82 by holding the IC tag 90 on the lid member 95 and placing the lid member 95 inside the main body head 86.

  Further, in the tag-attached bolt 80, slits 89 and 99 along the axial direction of the tag-attached bolt 80 are provided on the side surfaces of the main body head 86 and the lid member 95. Therefore, when the lid member 95 is contracted from the state in which the slit 99 is sandwiched, the lid member 95 is easily fitted into the hollow portion 26 and has a restoring force. Therefore, when the lid member 95 is fitted to the hollow portion 26, a restoring force always acts on the peripheral side surface 26b surrounding the hollow portion 26, and the fitting strength of the lid member 95 to the hollow portion 26 is improved. Become. Further, by setting one of the slit 89 of the main body head 86 and the three slits 99 formed in the lid member 95 at the same position in the circumferential direction, an eddy current generated along the circumferential direction of the head 82 is reduced. It can be cut off or reduced efficiently, and the radio wave transmitted from the reader is prevented from being weakened by the eddy current, so that the IC tag 90 and the reader can communicate accurately.
