The present inventors are in the midst of research and development regarding a system for monitoring the running of a bicycle. In this system, a reader for an IC tag is installed in the vicinity of a road or a sidewalk. However, depending on the road environment, there are places that can only be installed on either the left or right side of a traveling bicycle.
In such a case, there is a problem that reading is difficult if the IC tag is attached to a bicycle frame or a mudguard. In addition, since the frame and the mudguard are metal products, there is a problem that the reading is adversely affected.

  Therefore, an object of the present invention is to provide a bicycle mounting structure for an IC tag that can reliably read information stored in the IC tag from both the left and right sides of the bicycle.

In order to achieve the above object, the bicycle mounting structure for an IC tag according to the present invention is such that an internal space is provided in a reflection plate attached to a spoke of a bicycle wheel, and the IC tag is built in the internal space.
Further, the internal space of the reflector is sealed to form a waterproof structure.
Further, the IC tag is sandwiched and sealed between a first waterproof sheet member and a second waterproof sheet member.

  Engaging grooves for inserting the spokes are formed at both ends of the reflector so as to approach from the radial outer side of the spokes. The spokes are inserted into the engaging grooves and the spokes are engaged with the spokes. A retaining member made of a metal plate having a V-shaped cross section for preventing separation from the groove is provided, and the retaining member is bent inward from the end of the insertion port into which the spoke is inserted. In addition, it has a warped protrusion that prevents the spoke from returning to the outside.

  In addition, an engagement groove for inserting the spoke is formed at both ends of the reflector so as to approach from the radial outside of the spoke, and the engagement groove is opened through the engagement groove in the left-right direction. A locking pin for blocking is provided.

  According to the bicycle mounting structure of the IC tag of the present invention, the information stored in the IC tag can be read from either the left or right side of the traveling bicycle. It can be read reliably without being adversely affected by radio wave interference or the like from large metal parts such as frames, mudguards, handles, or the human body.

It is a figure which shows another embodiment, (a) is a side view, (b) is a plane sectional view.

Hereinafter, the present invention will be described in detail based on the illustrated embodiment.
As shown in FIGS. 1 to 3, an embodiment of the present invention includes a flat reflector 1 attached to a spoke S of a bicycle wheel. The side-view oblong (elliptical) reflector 1 is a side reflector that reflects light to the side of the bicycle.
The reflector 1 has an internal space 10. The UHF band IC tag 2 in which information such as an identification number (symbol) of an 8- to 14-digit bicycle is stored in the internal space 10. The IC tag 2 has an IC chip 21 that stores information, and an antenna unit 20 connected to the IC chip 21. The IC tag 2 is attached to one of the left and right inner walls forming the internal space 10 via an adhesive sheet member (not shown). The surface of the antenna unit 20 having a wide transmission / reception range (high sensitivity) is disposed substantially parallel to the left and right side surfaces (left and right side surfaces of the bicycle) of the reflector plate 1.

  Moreover, the reflecting plate 1 includes a first side plate member 1A and a second side plate member 1B that are formed of a resin such as acrylic and have a reflecting portion that can reflect light emitted from the outside. The first side plate member 1 </ b> A and the second side plate member 1 </ b> B are fitted face-to-face and fixed integrally with an adhesive or the like to form the reflection plate 1. An elastic sealing material 17 made of resin or rubber is interposed in a fitting portion that surrounds the internal space 10, and the internal space 10 is sealed to form a waterproof structure. Instead of the elastic sealing material 17, an adhesive sealing agent may be applied to form a sealed waterproof structure.

  The reflecting plate 1 has engaging grooves 12 and 12 for inserting the spokes S at both ends, approaching from the radial outside of the spokes S. The engagement groove 12 is formed along the longitudinal direction of the spoke S. Locking convex portions 11a and 11a projecting inward and leftward and rightward of the engaging groove 12 are formed on the groove side wall portions 11 and 11 forming the engaging groove 12, respectively. The locking convex portion 11a is provided on a tongue-like rocking wall portion 11b formed in a cantilever shape by a U-shaped notch portion 11c passing through the groove side wall portions 11 and 11 in the left-right direction. .

  Then, the spoke S is inserted into the storage space 15 between the groove inner wall portion 13 forming the engagement groove 12 and the locking projection 11a, and the spoke S is prevented from being separated from the engagement groove 12. A retaining member 3 is provided.

  3 and 4, the retaining member 3 is formed by bending a metal plate-like member into a V-shaped cross section. The retaining member 3 has an engagement space 30 into which the spoke S is inserted, and an insertion port portion 3 </ b> A for inserting the spoke S into the engagement space 30. Furthermore, it has a pair of left and right warped protrusions 3a, 3a in the shape of a door that is bent inward (engagement space 30) from the left and right ends of the insertion port 3A. In addition, it can be said that the outer shape of the retaining member 3 is formed in a hook shape that is pointed in a plan view. Further, as shown in FIG. 5A, the left and right member width dimensions W3 in the natural state are formed slightly larger than the groove width dimension W12.

The retaining member 3 is disposed in the storage space 15 in advance before attaching the reflecting plate 1 to the spoke S.
As shown in FIG. 5A, the retaining member 3 is inserted in an arrow X direction (a direction in which the spoke S is to be inserted) from the outside toward the storage space 15 in a plan view.
As shown in FIG. 5B, the retaining member 3 is inserted while being elastically deformed so as to be narrowed to the left and right inward by the reaction force while expanding the locking convex portion 11a to the left and right outward.
As shown in FIG. 5 (c), when the retaining member 3 gets over the locking projection 11 a, the locking projections 11 a and 11 a return to their original positions, and the retaining member 3 expands in the storage space 15. Since the groove width dimension W12 is smaller than the member width dimension W3, the warped protrusions 3a, 3a close the insertion port 3A of the retaining member 3. Further, the end of the insertion port 3A (the base end of the warped protrusion 3a) comes into contact with the locking projections 11a and 11a, so that the retaining member 3 is removed from the storage space 15 (opposite of the arrow X). Direction) is prevented.

And the reflecting plate 1 which accommodated the securing member 3 in both ends is attached to the spoke S. FIG.
First, as shown in FIG. 5C, the engagement groove 12 is made to approach the spoke S from the radial outside of the spoke S. The spoke S is inserted into the engagement groove 12 from the arrow X direction. The spoke S gets over while pushing the locking projection 11a in the middle.
As shown in FIG. 5D, the warped protrusions 3a, 3a of the retaining member 3 are elastically deformed so as to be pushed outward in the left and right directions by the spokes S that have passed over the locking projection 11a. The spoke S is inserted into the engagement space 30.
As shown in FIG. 5 (e), when the spoke S is inserted into the engagement space 30, the warped protrusions 3a and 3a are restored (by a resilient force such as a leaf spring) so as to close the insertion port 3A. Thus, the spoke S is prevented from returning outward (in the direction opposite to the arrow X) again. In this way, the IC tag 2 is attached to the bicycle by inserting the spokes S into the retaining members 3 and 3 of the engagement grooves 12 and 12 at both ends.

Next, another embodiment of the present invention is shown in FIGS.
The reflector 1 attached to the spoke S of the wheel is formed in a rectangular shape and has an internal space 10 in which the IC tag 2 is accommodated. The first side plate member 1A and the second side plate member 1B are ultrasonically fused, and the internal space 10 is sealed to form a waterproof structure.

  A through-hole 19 penetrating in the left-right direction is provided in the groove side wall portions 11, 11 forming the engagement groove 12. More specifically, the through hole 19 penetrates the swing wall portion 11b.

  Then, after the spoke S is inserted into the storage space 15, a resin-made locking pin 18 that is press-fitted into the through hole 19 is provided. The locking pin 18 has a warped portion 18a on the distal end side through which the through hole 19 is inserted, and has a bulging contact portion 18b on the proximal end side.

  The warped portion 18a is elastically deformed when inserted through the through hole 19, and is restored after being inserted and locked to the outer surface of the groove side wall portion 11 on the inserted side. The locking pin 18 penetrates the engaging groove 12 in the left-right direction, and the warped portion 18a and the contact portion 18b are locked to the groove side wall portions 11, 11, respectively, so that the movement in the left-right direction is restricted.

  The locking pin 18 passes through the engagement groove 12 and is skewered to prevent the engagement groove 12 from opening. The swing wall portions 11b and 11b are inadvertently opened, and the spoke S is prevented from getting over the locking convex portion 11a and returning outward. In this way, the spokes S are inserted into the engagement grooves 12 and 12 at both ends, and the IC tag 2 is attached to the bicycle by being prevented from coming off by the locking pins 18.

  Next, FIG. 10 shows another embodiment of the present invention. The IC tag 2 is sandwiched and sealed between a first waterproof sheet member 51 made of resin and a second waterproof sheet member 52 made of resin. The first sheet member 51 and the second sheet member 52 are bonded together by thermocompression bonding (fusion), ultrasonic fusion, an adhesive, or the like. In the case of such a waterproof structure, omission of the sealing material 17 (or sealant) interposed between the first side plate member 1A and the second side plate member 1B, or the first side plate member 1A and the second side plate member 1B. It is possible to omit the ultrasonic fusion with the reflector 1 and facilitate the assembly of the reflector 1. Moreover, even if the reflector 1 is cracked due to a contact accident or the like, the waterproofness of the ID tag 2 is maintained. In order to further improve waterproofness, a waterproof structure with a seal material 17 (or sealant) interposed between the first side plate member 1A and the second side plate member 1B, or the first side plate member 1A and the second side plate member. It is also desirable to use a waterproof structure by 1B ultrasonic fusion.

  Here, a bicycle travel management system suitable for using the IC tag bicycle mounting structure of the present invention will be described. The bicycle management system is used to examine how to set up a road for bicycles (routes such as commuting and school routes for bicycles) to prevent contact accidents between pedestrians and bicycles. In order to obtain data such as what route commute to school or school, or to monitor whether or not the bicycle is traveling on a designated bicycle commute / route (route) System.

In the bicycle travel management system, for example, a plurality of data readers of the IC tag 2 are installed within a predetermined management range assumed as a commuting / commuting route from a station to a school or a company.
