Description

The present invention relates to a locking tool used when connecting a product and various tags, or various boxes requiring security and its lid , and more particularly, UHF radio wave band for recording and reading information by radio waves. The present invention relates to a locking tool that also serves as a tag.

In recent years, a recognition technology by radio communication called RFID (Radio Frequency Identification) has been attracting attention in place of a widely used barcode.
This technology records or reads data using radio waves on an IC chip incorporated in a medium such as a card or tag, and recognizes it by wireless communication via an antenna.
The reason why this technology is attracting attention is that the amount of information that can be stored is much larger than that of a barcode, and because it can be performed by wireless communication, it is far from being close to a contact type such as a barcode. Compared to being able to communicate over a long distance, and even with barcodes having to handle individual communication processing, RFID can perform communication processing together, and even traceability from product production to consumption However, the effects are immeasurable, and in each field, the introduction of the technology is being considered from an early stage.
Among them, mainly in the field of apparel etc., even with the same design, there are many types of sizes and colors compared to other products, especially in the sales floor, as well as the inventory management in the backyard Because of this, there is a momentum to quickly implement various types of management using RFID.
However, in spite of the above-mentioned momentum, other than a locking piece called a common name tag pin used when attaching a brand tag or price tag to a product, or a sealing piece called a common name loop lock that is attached in a loop shape In addition, it is necessary to attach an RFID tag by some method, which increases the man-hours. For RFID, for example, a metal antenna is disposed on a PET film by printing or edging, and is electrically coupled to the antenna. Since the IC chip is mounted, it becomes a considerably large area (upsizing), which is not preferable from the display design, and the RFID is delicate, so the RFID must be protected from the viewpoint of improving the resistance, and it becomes expensive. For the reason, it is not yet popular now.

Japanese Patent No. 4352232 The patented invention, whose applicant is the patentee, aims to provide a tag coupling device that can collect the tag to be collected after ensuring the security, and further, the tag to be collected together with the brand tag and the price tag. The purpose is to provide a tag coupling device that can communicate to the consumer even if only the tags that should be collected can be collected, and the strips are extended from the head. The head and the belt-like portion are provided with a lock mechanism that locks them together, or a lock mechanism that locks the belt-like portion in cooperation with other articles on the opposite side of the head from the head. A mechanism for attaching and detaching the connecting tool and a tag formed independently of the connecting tool is provided in the connecting tool and the tag, and the attaching and detaching mechanism removes the connecting tool at least when the tag is removed from the connecting tool. Without external operation mechanism It is obtained by configured to separate the tag and coupler.

Since the above-mentioned patented invention can be reused, the same tag can be used many times. The more the number of use, the lower the cost per use, and the information written on the tag from stores etc. While it has the advantage of not leaking to the outside, the number of man-hours for attaching and detaching tags increases, so despite the fact that it has been evaluated as a good proposal in the field of apparel, etc. , It is in a state of being unable to complete the introduction.

Therefore, the present invention is attached to the product etc. with the work that is almost the same as the mounting workability of the currently used locking and sealing tools to the product, and in a state where the display design is not affected by downsizing. and RFID reduction, by a for optimal communication performance corresponding to an equal application to not read until further unnecessary RFID, can above simplifies various management was such products, in addition, inventory, back A UHF tag locking device that can perform various types of management such as proper inventory management in the yard, customer interest surveys such as picking up products, prevention of theft, and simplification of cash register operations.

A first embodiment of the locking device will be described.
1 to 5, a belt-like portion 2a is extended from the head portion 1a and is integrally formed of synthetic resin. The strip portion 2a is formed in a filament shape. In this case, the belt-like portion 2a is initially made short in a slightly thick filament shape, and is elongated and elongated while extending in the longitudinal direction while being molecularly oriented.
Advantage of to the strip portion 2a stretching, polyamide, when injection molding a thermoplastic resin such as polypropylene as a raw material, the initially shaped for strip portion 2a is thick, rather easy molding good fluidity of the resin, The stretching After that, the molecular orientation can increase the tensile strength in the longitudinal direction of the band-shaped portion 2a, and also the flexibility in the band-shaped portion 2a can be obtained because the waist is weak in the bending direction.
The strip portion 2a is preferably stretched in order to obtain the above-mentioned advantages, but may be unstretched when strength and flexibility are not important.

Next, the locking mechanism Ka in which the head 1a and the belt-like portion 2a are locked to each other will be described with reference to FIGS.
In this embodiment, an arrowhead-shaped coupling portion 3a having blades 31a that can be reduced and enlarged is provided on the free end side of the belt-like portion 2a. The blade 31a that can be reduced and enlarged is configured such that the blade 31a can be contracted inward by forming a hollow portion 32a. Moreover, the blade | wing 31a of the coupling | bond part 3a becomes a shape which spreads, so that it goes to the head 1a side from the front end side in FIG. 1 at the time of expansion.
Moreover, the locking part 11a of the coupling | bond part 3a is formed in the head 1a. The axis of the locking portion 11a is arranged in the head 1a so as to be parallel to the axis of the belt-like portion 2a in a straight state. The locking portion 11a is a small than outer dimensions upon expansion of the coupling portion 3a (blade 31a), and the stationary teeth 112a having a large hole 111a than the outer dimension of the time of reduction of the coupling portion 3a .

On the other hand, an IC chip portion 4a is disposed on the head 1a. 3 and 4, the IC chip portion 4 a is a metal frame 41 a having end portions 411 a and 412 a which are electrically cut in a C shape in front view, and an IC electrically connected to the end portions 411 a and 412 a. It consists of a chip 42a.

  The locking tool having the IC chip portion 4a arranged on the head 1a in this way is formed by molding with synthetic resin. However, if the IC chip portion 4a is inserted in the mold in advance during the molding, Since it can seal in 1a, it is preferable.

Vaporization locking tool outside circumference which is disposed an IC chip portion 4a on the head 1a configured as described above, conductive material, e.g., aluminum, gold, in gold palladium, platinum palladium, in a vacuum carbon, chromium, etc. by, skipping the atoms and molecules in the entire locking tool periphery, when the skipped atoms or molecules to reach the outside of the circumferential locking tool, for coating of eventually being cooled, the vapor deposition of metal such as so-called conductive The applied conductive film 51a is applied to the outer periphery of the locking tool to form the antenna portion 5a .
The antenna portion 5a is electrically connected to the IC chip portion 4a so as to function as an antenna of the IC chip portion 4a. The length of the antenna unit 5a is basically set to a total length of ½ wavelength of the desired UHF radio wave band. Then, an antenna outer end 53a is formed by providing a non-antenna portion 52a, which is a portion where the conductive film 51a is not formed, at a portion that is 1/2 of the length of the antenna portion 5a, that is, about 1/4 of the wavelength. (See FIGS. 1 and 5). Strictly speaking, the impedance becomes inductive at a quarter wavelength (having a positive imaginary component), and impedance matching with the feeder line becomes difficult. It also means matching the resistance.
In this embodiment, the non-antenna portion 52a is masked during deposition of the conductive material so that the conductive film 51a is not formed.

上記表１に記載したように、ループにしたアンテナ部５ａの非アンテナ部分５２ａの長さを５ｍｍ〜２５ｍｍまで５ｍｍ間隔で変化させた場合、非アンテナ部分５２ａの長さが長いほど通信距離が伸び、非アンテナ部分５２ａの長さが２５ｍｍの時にはアンテナ部を直線的にしたダイポールアンテナを１００％とした場合、通信距離の減衰率が３０％程度になることが判明した。
これは、ループにしたアンテナ部５ａの非アンテナ部分５２ａがない場合は、ＩＣチップ部４ａの左右のアンテナ部５ａの電位が正負で打ち消し合い、アンテナ部５ａがアンテナの役目を果たさないのに対して、アンテナ部５ａをループにしてもアンテナ部５ａにアンテナ外端５３ａがある場合（この実施例では、導電性材の蒸着時にマスキングすることにより導電膜５１ａが形成されないようにして非アンテナ部分５２ａを形成している）は、アンテナ部５ａがアンテナの役目を果たすので、これまでは、所望の通信距離を得るために、リーダラーター側で出力の調整をしたり受信アンテナの向きを変える等、かなり微妙な調整を長期間かけて行っていたのにそれをする必要がなく、用途に応じて非アンテナ部分５２ａの長さを変えるだけで所望の通信距離を簡単に得ることができ、顧客等の要望に対して迅速に対応できる作用効果がある。According to the experiment, a non-antenna portion 52a is provided at a middle position of the antenna portion 5a when the coupling portion 3a is fitted in the head 1a and the belt-like portion 2a is looped, and only the length of the non-antenna portion 52a is changed. The communication distance was measured. The results are shown in Table 1.

As described in the above Table 1, when the length of the non-antenna portion 52a of the antenna portion 5a which is in the loop varied 5mm intervals until 5 mm to 25 mm, the communication distance is extended as the length of the non antenna portion 52a is longer It has been found that when the length of the non-antenna portion 52a is 25 mm, the attenuation factor of the communication distance is about 30% when the dipole antenna having a linear antenna portion is defined as 100%.
If this is not the non antenna portion 52a of the antenna portion 5a which is in the loop, cancel the potential of the right and left antenna portion 5a of the IC chip portion 4a is positive and negative, while the antenna portion 5a does not play a role of an antenna Te, when the antenna portion 5a has an antenna outer end 53a to the antenna portion 5a is also in the loop (in this embodiment, the non-antenna as the conductive film 51a is not formed by masking during deposition of the conductive material Since the antenna portion 5a serves as an antenna, the output adjustment or the direction of the receiving antenna is changed on the reader / writer side so far to obtain a desired communication distance. etc., it is not necessary to do it to have done over an extended period of time rather delicate adjustment, simply by changing the length of the non antenna portion 52a depending on the application Desired communication distance can be obtained easily, there is a rapidly acting effect of cope with demands such as customers.

Next, the operation of the locking mechanism Ka will be described with reference to FIGS.
First, from the action of the locking mechanism Ka in which the head 1a and the belt-like portion 2a are locked to each other, the belt-like portion 2a is bent 180 degrees so that the coupling portion 3a is formed in the hole 111a of the head 1a as shown in each figure. Plug in. When the coupling portion 3a is inserted into the hole 111a, the blade 31a of the coupling portion 3a contracts in accordance with the size of the hole 111a, returns to the original position when the blade 31a passes through the hole 111a, and is reversed by the fixed tooth 112a. To prevent.
That is, since the attachment of the locking head 1a and the coupling portion 3a can be performed simply by inserting, the workability when attaching the tag P to the product G is extremely improved as shown in FIG. .
In this embodiment, the coupling portion 3a can be reduced and enlarged, and the locking portion 111a of the head 1a is a fixed tooth 112a. However, although not shown, for example, the coupling portion 3a as shown in the above embodiment is used. The hollow portion 32a can be eliminated, and the locking portion 111a of the head 1a can be formed by providing a radial groove in the fixed tooth 112a portion described in the above embodiment, or by thinning the fixed tooth 112a portion. By making it flexible, the fixed teeth 112a may be reduced and enlarged.
As described above, the locking mechanism Ka the head 1a and the belt portion 2a with each other engage with each other is locked condition, the strip portion 2a in FIG. 1, the loop as shown in FIG.

Next, the RFID action by the IC chip portion 4a and the antenna portion 5a when the locking tool is in a loop state will be described.
When there is a locking tool in the electric field, the antenna unit 5a is adapted to the frequency of the UHF radio band as described above, so that the maximum voltage at the antenna outer end 53a portion formed by the non-antenna portion 52a. Is induced to resonate. By this action, the two antenna parts 5a and the IC chip part 4a are in an electrically coupled state, and the antenna part 5a, in other words, the loop-like band-like part 2a serves as a dipole antenna that extends the communication distance.
Incidentally, if the conductive film 51a into two one antenna portion 5a of the antenna portion 5a so as not to exist, the strip portion 2a between the one antenna portion 5a and the non antenna portion 52a is not play the role of an antenna In addition, since only the antenna 54a of the belt-like portion 2a between the other antenna portion 5a and the non-antenna portion 52a serves as an antenna, the belt-like portion 2a can be a monopole antenna having a short communication distance. Depending on the customer, the range of customer choices can be expanded.
In any of the above cases, it is natural that the distance between the frame 41a and the conductive film 51a should be as close to zero as possible in order to generate the above-described magnetic field.

If the conductive film 51a directly touches a product such as clothing, the IC chip 42a may be damaged by static electricity charged on the product. In this case, the conductive film 51a is made of an insulator such as enamel. It is effective as a countermeasure against static electricity.
In this case, if the enamel film of the conductive film 51a and the frame 41a are brought into contact with each other, the frame 41a is substantially brought close to the outer peripheral portion of the head 1a, so that there is an advantage that it is easy to manufacture electrically. is there.

As described above, in the locking device of the first embodiment, the IC chip portion 4a corresponding to the radio wave in the UHF band is resin-sealed to the locking device of the approximate form currently in circulation, and the non-antenna of the band-shaped portion 2a portion 52a by providing the non-outer periphery and the conductive film 51a by performing deposition by the conductive material described above on the outer circumference of the head 1a (FIG. 1, the antenna outer end 53a between the FIG. 5), the strip portion 2a The antenna unit 5a that receives and transmits UHF band radio waves for operating the IC chip unit 4a is used, and the positional relationship between the antenna unit 5a and the IC chip unit 4a is a monopole type or dipole type electrical coupling relationship. .
Therefore, it can be attached to the product etc. with work that is almost the same as the attachment workability of the currently used locking and sealing tools to the product, and the display design is not affected by downsizing. in a state where it is possible (the state in which the belt-like portion to loop in this example), the exchange of information between the IC chip and the system, for example, inventory, optimum inventory management in the backyard, etc. customer picks up the goods It is possible to perform various management such as the degree of interest in merchandise of customers, theft prevention, simplification of cash register work, and the like.

Next, a second embodiment of the locking tool shown in FIGS. 6 and 7 will be described.
The free end side of the belt-like portion 2b is provided with an arrowhead-shaped coupling portion 3b having blades 31b that can be reduced and enlarged, and the blades 31b that can be reduced and enlarged are contracted inward by forming a hollow portion 32b. The blade 31b of the coupling portion 3b is shaped so as to expand from the tip side toward the head portion 1b side in FIG. 6 when enlarged, and the head portion 1b has the shape of the coupling portion 3b. The locking portion 11b is formed, and the axis of the locking portion 11b is disposed in the head 1b so as to be parallel to the axis of the belt-like portion 2b in a straight state. The point that the fixed tooth 112b is smaller than the outer dimension when the part 3b (blade 31b) is enlarged and larger than the outer dimension when the part 3b (blade 31b) is formed, and the head 1b includes the first embodiment. The same configuration as the IC chip part 4a shown in FIG. Have arranged the IC chip portion 4b having, IC chip portion 4b is a front view C shape electrically cut end 411b, 412b made of a metal having a (not shown) frame 41b and the end portion 411b, 412b point consisting of an IC chip 42b in which the electrical connection is the same as in example 1.

Next, differences from the first embodiment will be described.
The strip portion 2b, a metal, a conductor 51b made of carbon fiber or twisted wires or the like, as shown in FIG. 6 from the head 1b up to the coupling portion 3b, that has first passed through.
Also, the length of the antenna 5b is only set non antenna portion 52b in 1/4 parts worth of the wavelength of UHF radio band. The non-antenna portion 52b is formed of a resin block 521b and a protruding conductor 513b arranged so as to protrude from the block 521b. The head 1b, the block 521b, and the coupling portion 3b are connected to the conductor 51b. After the insertion, resin molding is performed at the same time, and after molding, the conductor 513b protruding from the block 521b is cut and removed to form an electrical non-antenna portion 52b and an antenna outer end 53b. Strictly speaking, the impedance becomes inductive at a quarter wavelength (having a positive imaginary component), and impedance matching with the feeder line becomes difficult. It also means matching the resistance.
The outer periphery of the conductor 51b is subjected to an electrical insulation process in advance.

As is apparent from FIG. 6, the conductor 51b is penetrated from the locking head 1b to the coupling portion 3b at the time of molding when molding the head 1b and the coupling portion 3b with resin. The coiled conductor 51b is automatically unwound so as to be along the parting surface of the mold, and a predetermined position in the cavity forming the mold head 1b and the cavity 3b is formed. If it is made to pass, a large number of latches can be formed continuously on one long conductor 51b, and the conductor 51b may be cut for each latch after the molding is completed.
Since the cut surface 511b of the locking member from which the conductor 51b has been cut comes into contact with the product, static electricity may be generated particularly in clothing and the like, so that the IC chip 4b is prevented from being damaged by static electricity. However, in this embodiment, in order to reduce the number of manufacturing steps, in this embodiment, the protrusion 114b (the protrusion 522b in the block 521b) is formed around the cut surface 511b of the conductor 51b. The formed cut surfaces of the conductor 51b are prevented from coming into direct contact with the product or the like.

  On the other hand, since the conductor 51b is cut also at the tip portion of the coupling portion 3b, this portion also needs to be electrically insulated. In this embodiment, the cut surface 512b of the coupling portion 3b As shown in FIG. 6, the cutting surface 512b at the tip of the coupling portion 3b does not protrude from the head 1b so that the cutting surface 512b of the conductor 51b directly contacts a product or the like. Is preventing.

As described above, in the locking tool of Example 2, while the material of the band-shaped part 2b is a conductor, the band-shaped part 2b is integrated with other parts made of resin, and the non-antenna part 52b is: A resin block 521b and a protruding conductor 513b arranged so as to protrude from the block 521b are formed, and the head 1b, the block 521b, and the coupling portion 3b are simultaneously molded with the conductor 51b inserted. Then, after the molding, the conductor 513b protruding from the block 521b is cut and removed to form an electrical non-antenna portion 52b, so that the antenna outer end 53b is formed on the conductor 513b which is the antenna portion 5b. The antenna unit 5b that receives and transmits UHF band radio waves for operating the IC chip unit 4b is used. The antenna unit 5b and the IC chip unit 4b It is possible communicate with a weak radio wave can be reduced the electrical resistance of the positional relationship in terms of the dipole-type electrical coupling relationship. In other words, there is an effect that the communication distance can be extended .

Next, a third embodiment of the locking tool shown in FIG. 8 will be described.
In this embodiment, a head portion 1c is obtained by directly inheriting the components excluding the IC chip portion 4a of the head portion 1a of the locking member of the first embodiment (FIGS. 1 to 5), and this head portion 1c is shown in FIG. The heads 1c are connected to each other by being arranged on the axis target with reference to the Y-Y line.
The head 1c is provided with a window 115c for forming a locking portion 11c necessary for the mold configuration used for mass production molding.
And the strip | belt-shaped part 2c is each extended from the connected left and right heads 1c, and forms the coupling | bond part 3c in the free end part of each strip | belt-shaped part 2c.
On the other hand, the IC chip portion 4c has the same configuration as that of the first embodiment, and is electrically connected to the metal frame 41c having end portions 411c and 412c that are electrically cut in a C shape when viewed from the front, and the end portions 411c and 412c. And an IC chip 42c.

As in the first embodiment , the entire outer periphery of the locking tool configured as described above is obtained by vaporizing a conductive material such as aluminum, gold, gold palladium, platinum palladium, carbon, chromium, etc. When the scattered atoms and molecules reach the entire outer periphery of the locking tool, the film is cooled and eventually becomes a film, and the conductive film 51c is deposited with a so-called conductive metal or the like. Is applied to the outer periphery of the locking tool to form the antenna portion 5c .
The antenna portion 5c is electrically connected to the IC chip portion 4c so as to function as an antenna of the IC chip portion 4c.
The length of the antenna unit 5c is basically set to the entire length of a half wavelength of a desired UHF radio wave band. Then, an antenna outer end 53c is formed by providing a non-antenna portion 52c, which is a portion where the conductive film 51c is not formed, at a portion that is 1/2 of the length of the antenna portion 5c, that is, about ¼ of the wavelength. Yes. Strictly speaking, the impedance becomes inductive at a quarter wavelength (having a positive imaginary component), and impedance matching with the feeder line becomes difficult. It also means matching the resistance.
In this embodiment, the non-antenna portion 52c is masked during deposition of the conductive material so that the conductive film 51c is not formed.

The dependence of the communication distance on the length of the non-antenna portion 52c has been confirmed by experiments as shown in Table 1 above, and the results can also be applied to this embodiment.

Further, since the action of the locking mechanism Kc is the same as that described in the paragraph “0027”, description thereof is omitted here, but as shown in FIG. A loop as shown in FIG. 8 can be formed by inserting the coupling portion 3c of each band-like portion 2c into the hole 111c of the portion 1c.
Note that the band-like part 2c is drawn in parallel with the band-like part 2c on the extending proximal side and the band-like part 3c on the coupling part 3c side due to the problem of drawing in FIG. Note that is a large arc shape (the arc of the phantom line shown in FIG. 8 is small because of limited space).
Further, if the waist of the belt-like portion is strengthened, the arc (the phantom line in FIG. 8) when formed in a loop shape can be formed large. This has a great relationship with the antenna action of the band-shaped portion described in the next paragraph “0040”.

Next, the RFID action when the left and right belt-like portions 2c ( antenna portion 5c ) shown in FIG. 8 and the head portion 1c are locked to form a loop will be described.
When there is a locking tool in the electric field, the antenna portion 5c is adapted to the frequency of the UHF radio band as described above, so that the maximum voltage at the portion of the antenna outer end 53c formed by the non-antenna portion 52c. Is induced to resonate. By this action, the two left and right antenna portions 5c and the IC chip portion 4c are in an electrically coupled state, and the antenna portion 5c, in other words, the left and right loop-like band portions 2c, each serve as a dipole antenna that extends the communication distance. However, if the arc (the phantom line in FIG. 8) when the belt-like portion 2c is looped becomes large, the antenna portion between the base end side extending from the head 1c of the belt-like portion 2c and the coupling portion 3c side. The angle of 5c is close to 90 degrees, and it also serves as a cross dipole antenna.
If the conductive film 51c does not exist in one of the left and right antenna portions 5c , the portion does not serve as an antenna, and only the other antenna 54c serves as an antenna. In this respect, the range of customer choices can be expanded.
In any of the above cases, it is natural that the distance between the frame 41c and the conductive film 51c should be as close to zero as possible in order to generate the above-described magnetic field.

If the conductive film 51c directly touches a product such as clothing, it is considered that the IC chip 42c is damaged by static electricity charged on the product. In this case, the conductive film 51c is made of an insulator such as enamel. It is effective as a countermeasure against static electricity.
In this case, if the enamel film of the conductive film 51c and the frame 41c are brought into contact with each other, the frame 41c is substantially brought close to the outer peripheral portion of the head 1c, so that there is an advantage that it is easy to manufacture electrically. is there.

As described above, in the locking tool of Example 3, the positional relationship between each antenna portion 5c and the IC chip portion 4 is a dipole type or cross dipole type electrical coupling relationship.
Therefore, it is possible to make the belt-shaped portion an antenna for high-performance communication with a locking tool having a size similar to that of a currently used locking tool or sealing tool. In addition, installation workability can be attached to products etc. with work that is almost the same as before, and the range of directivity for long-distance communication and transmission / reception by wireless with no influence on display design due to downsizing Exchange of information between IC chip and system, for example, inventory, proper inventory management at backyard, customer's interest in goods such as picking up goods, anti-theft, cash register Various kinds of management such as simplification of work can be performed at a place away from the product and effectively without worrying about the direction of transmission / reception.

Next, a fourth embodiment of the locking tool shown in FIGS. 9 to 14 will be described.
This embodiment is different from the first embodiment in that the locking portion 11d and the IC chip portion 4d are arranged with the phase shifted by 90 degrees with respect to the axis of the belt-like portion 2d. Although the depth structure in the front view of the chip portion 4d is partially different from that of the first embodiment, the description of other structures is the same as that of the first embodiment, and the description thereof is omitted.
9 to 14, especially as shown in FIG. 12, viewed from the front straight portion 413d in the flat plane view, and extends along with the arcuate 4131d an arcuate outer periphery of the head 1d. This is a measure for improving the electrical coupling relationship between the antenna portion 5d and the IC chip portion 4d by increasing the proximity area between the conductive film 51d on the outer periphery of the head and the circular arc 4131d.

Figure 11 mainly in FIG. 13 in the following, with reference to FIG. 12, a description will be given of the operation of the locking mechanism Kd.
First, from the action of the locking mechanism Kd in which the head 1d and the belt-like portion 2d lock each other, the belt-like portion 2d is bent 90 degrees in front view, and the coupling portion 3d is connected to the head 1d as shown in FIG. Insert into hole 111d. That is, the attachment of the locking member head 1d and the coupling portion 3d is made by bending the coupling portion 3a by 180 degrees in the first embodiment, whereas the coupling portion 3d is bent by 90 degrees in this embodiment. since perform the insertion work only by Mase, as shown in FIG. 14, when attaching the tag P in the product G, its workability is extremely good.
As described above, when the head 1d and the strip portion 2d is engaged locks mutually locking mechanism Kd is locked with each other, the strip portion 2d is 13, the loop as shown in FIG. 14.

As the following, the locking tool of Example 4, the IC chip portion 4d corresponding to the radio wave of the UHF band in locking tool approximate form in circulation as well as resin sealing, in the head 1d locking device outside circumference to the conductive film 51d except the engaging portion 11d, the strip portion 2d by providing the antenna outer end 53d in other words, to receive and transmit radio waves in the UHF band for operating the IC chip portion 4d The antenna portion 5d was used, and the positional relationship between the antenna portion 5d and the IC chip portion 4d was a monopole type or dipole type electrical coupling relationship.
Therefore, the current popular that can be attached to the product or the like in and are mounting workability and殆N etc. change there is no work on the goods of the locking device and the closure arrangement, yet to ensure there is no impact on the display design by downsizing Exchange of information between IC chip and system, for example, inventory, proper inventory management in backyard, customer's interest in goods such as picking up goods, theft prevention, cash register work Various management such as simplification can be performed.

A fifth embodiment of the locking tool will be described.
Since this embodiment is characterized in that the IC chip portion 4e is also used as a locking mechanism on the head side, this point will be mainly described. However, portions not described here are those in Embodiment 4 (FIG. It is added that it is the same as 9 to FIG.
15A and 15B, an IC chip portion 4e is basically formed of a frame 41e having a C-shaped cross section in plan view and an IC chip 42e electrically connected to end portions 411e and 412e of the frame 41e. doing.
Frame 41e has a central hole of the frame 41e and the holes 111e of the holes 111d and the dimensions of the head 1d of Example 4, the resin provided on the flange 413e and the flange 413e provided on the outer periphery of the hole 111e of the frame 41e And a plurality of support holes 414e for supporting the frame 41e.
As shown in FIG. 15B, the IC chip portion 4e formed in this way is arranged so as to be approximately in the center in the head 1e when the head 1e is molded with resin. This is effective in insert molding by positioning the IC chip portion 4e in advance with a mold (pin on the mold forming the inner wall 113e) ( not shown) when the head 1e is molded.
The reason why the IC chip portion 4e is arranged in this way is that the frame 41e is also used as the locking mechanism Ke on the head 1e side instead of the hole 111d of the head 1d of the fourth embodiment.

As described above, the antenna portion 5e is formed by applying the conductive film 51e obtained by depositing a conductive metal or the like to the entire outer periphery of the locking tool except for the inner wall 113e in the head 1e.
Therefore, when the locking tool is formed in a loop shape, since the flange 413e of the frame 41e is close to the conductive film 51e, the conductive film 51e and the flange 413e are electrically coupled by magnetic field coupling, and the non-antenna portion A band-shaped portion 2e between 52e and the head 1e serves as a monopole antenna.

As described above, in this embodiment, since the IC chip portion 4e is also used as the locking mechanism Ke on the head 1e side, the head 1e can be reduced in size, and the locking tool and the UHF tag are also used. Thus, the downsizing of the locking tool can be further promoted.
In addition, if the frame 41e of the IC chip portion 4e is provided with a certain degree of rigidity, the IC chip portion 4e can be sandwiched between molds when forming the locking tool as described above. There are also advantages that can be achieved.

A sixth embodiment of the locking tool will be described.
16-20, from the head 1f, the band-shaped portion 2f is extended, and the locking mechanism Kf (FIG. 20) in which the head 1f and the belt-shaped portion 2f are locked to each other is the band-shaped portion 2f. An arrowhead-shaped coupling portion 3f having a blade 31f that can be enlarged and reduced is provided on the free end side of the blade 31f. The blade 31f that can be reduced and enlarged can form a hollow portion 32f, so that the blade 31f is contracted inward. In addition, the blade 31f of the coupling portion 3f has a shape that widens from the tip side toward the head 1f side when enlarged, and further, the head 1f includes the coupling portion 3f. A locking portion 11f is formed, and the locking portion 11f is smaller than the outer dimension when the coupling portion 3f (blade 31f) is enlarged, and has a fixed tooth 111f that is larger than the outer dimension when the coupling portion 3f is reduced. 112f, the IC chip part 4 on the head 1f And disposed, from the IC chip portion 4f is electrically cut end 411f viewed from the front C-shaped, metal frame 41f and the end portion 411f with 412f, the IC chip 42f in which the electrical connection to 412f This is the same as the fourth embodiment (FIGS. 9 to 14).

Next, differences from the fourth embodiment will be described.
The belt-like portion 2f is a conductor 51f made of metal, carbon fiber, stranded wire, or the like, and is first penetrated from the head 1f to the coupling portion 3f as shown in FIG. At this time, the conductor 51f is arranged along the outer periphery of the hole 111f with a slight gap from the outer periphery of the hole 111f of the locking portion 11f of the head 1f.
Further, the non-antenna portion 52f is provided in a portion where the length of the antenna 5f is ¼ of the wavelength. The non-antenna portion 52f is formed of a resin block 521f and a protruding conductor 513f arranged so as to protrude outside the block 521f, and the head 1f, the block 521f and the coupling portion 3f are connected to the conductor 51f. After the insertion, resin molding is performed at the same time. After molding, the conductor 513f protruding from the block 521f is cut and removed to form an electrical non-antenna portion 52f. Strictly speaking, the impedance becomes inductive at a quarter wavelength (having a positive imaginary component), and impedance matching with the feeder line becomes difficult. It also means matching the resistance.
The outer periphery of the conductor 51b is subjected to an electrical insulation process in advance.
On the other hand, a front view arc part 413f along the arc part of the conductor 51f is formed on the frame 41f of the IC chip part 4f arranged in the head 1f so that an electric field can be efficiently formed during transmission and reception. Yes.

As is apparent from FIGS. 16 to 18, the conductor 51 f is penetrated from the head 1 f of the locking tool to the coupling portion 3 f at the time of molding by the resin, the head 1 f and the block 521 f and the coupling. In forming the portion 3f, the coil-shaped conductor 51f is automatically unwound and placed along the parting surface of the mold, and the cavity for forming the mold head 1f and the cavity for forming the block 521f are formed. In addition, if it passes through a predetermined position in the cavity forming the coupling portion 3f, a large number of fasteners can be formed continuously on one long conductor 51f, and the conductor 51f is locked after the molding is completed. It will suffice to cut each tool.
Since the cut surface 511f of the locking tool from which the conductor 51f is cut comes into contact with the product, static electricity can be generated particularly in clothing, etc., so as to prevent damage to the IC chip 4f due to static electricity. However, in this embodiment, in order to reduce the number of manufacturing steps, a convex portion 114f (a convex portion 522f for the block 521f) is formed around the cut surface 511f of the conductor 51f. The formed cut surfaces of the conductor 51f are prevented from coming into direct contact with the product or the like.

  On the other hand, since the conductor 51f is also cut at the tip portion of the coupling portion 3f, this portion also requires electrical insulation. In this embodiment, the cut surface 512f of the coupling portion 3f Since it is used by being inserted into the portion 1f, the cut surface 512f at the tip of the coupling portion 3f does not protrude from the head 1f as can be seen from FIG. 20, and the cut surface 512f of the conductor 51f directly contacts the product or the like. Is preventing.

Next, the RFID action by the IC chip portion 4f and the antenna portion 5f will be described.
The band-like portion 2f of the locking tool is a conductor 51f that acts as the antenna portion 5f. However, in the coupled state of the head portion 1f and the coupling portion 3f, the locking portion 11f in the head portion 1f, that is, the hole 111f, in other words, For example, since there is no conductive material on the fixed tooth 112f and the inner wall 113f around the fixed tooth 112f, in the locked state (FIG. 20) of the locking mechanism Kf in which the head 1f and the belt-shaped portion 2f are locked together, the coupling portion 3f The head 1f is electrically insulated. Therefore, when the length of the band-like portion 2f is set to about ¼ of the wavelength of the UHF frequency, an effective condition for forming an electric field as the antenna portion 5f is obtained, and the role as a monopole antenna is obtained.
In the locking device of this embodiment, the conductor 51f of the belt-like portion 2f is made of metal, carbon fiber, stranded wire, etc. In addition to the effects described in the fourth embodiment, the electric resistance is small, so even a weak radio wave can be communicated. There is also an effect that becomes possible.

Example 7 of a locking tool will be described.
21 and 22, from the head 1 h, a point in which the band-shaped portion 2 h is extended, and a locking mechanism Kh in which the head 1 h and the band-shaped portion 2 h are locked to each other is the free end side of the band-shaped portion 2 h. In addition, an arrowhead-shaped coupling portion 3h having a blade 31h that can be reduced and enlarged is provided, and the blade 31h that can be reduced and enlarged is configured so that the blade 31h can be contracted inward by forming a hollow portion 32h. In addition, the blade 31h of the coupling portion 3h has a shape that expands from the tip side toward the head 1h side when enlarged, and further, the head 1h has a locking portion 11h of the coupling portion 3h. The locking portion 11h is a fixed tooth 112h having a hole 111h that is smaller than the outer dimension of the coupling portion 3h (blade 31h) when enlarged and larger than the outer dimension when reduced. The IC chip part 4h is arranged on the head 1h. That the IC chip portion 4h has to consist in a front view C-shaped electrically cut end 411h, metal frame 41h and the end portion 411h having 412h, IC chip 42h and that the electrical connection to 412h The band-shaped portion 2h is a conductor 51h made of metal, carbon fiber, stranded wire, or the like, and is penetrated from the head 1h to the coupling portion 3h. The outer periphery of the conductor 51h is subjected to electrical insulation treatment in advance. It should be noted that, since the cutting surface 511h of the locking member from which the conductor 51h has been cut may come into contact with a product, particularly in clothing, etc., static electricity may be generated, so that damage to the IC chip 4h due to static electricity is prevented. is a best done electrically insulated to the convex portion on the periphery of the cut surface 511h of the conductor 51h for fabrication man-hours reduction 114h (block 521 That each cut surface of the conductive member 51h forming the convex portion 522h) is prevented from directly contacting the product etc. In the (trailing ... f of each symbol in FIG. 16 ... read as h), since even cutting the conductor 51h in the tip portion of the coupling portion 3h, but this portion is also required electrical insulation treatment, the cut surface 512h of the binding portion 3h is a coupling portion 3h crowded difference in head 1h Since it is used, the cutting surface 512h at the tip of the coupling portion 3h does not protrude from the head 1h as can be seen from FIG. 22, so that the cutting surface 512h of the conductor 51h is prevented from coming into direct contact with goods or the like. The point is the same as Example 6 (FIGS. 16 to 20).

Next, differences from the sixth embodiment will be described.
21 and 22, the IC chip portion 4h also serves as the locking portion 11h of the head 1h.
In other words, in addition to making the frame 41h of the IC chip portion 4h annular, a collar 414h is attached, and a part thereof is cut away to provide an end 411h and an end 412h, and the ends 411h and 412h are annular. Extends outward.
The end portions 411h and 412h and the IC chip 42h are electrically coupled.
The inner dimension of the frame 41h is smaller than the outer dimension when the coupling portion 3h (blade 31h) is enlarged, and larger than the outer dimension when the coupling part 3h (blade 31h) is enlarged, and the hole 111h of the locking portion 11h. It also serves as a fixed tooth 112h.
The frame 41h is formed of a conductive material such as copper alloy or aluminum.

On the flange 414h of the frame 41h, a belt-like portion 2h made of a conductor 51h made of metal, carbon fiber, stranded wire or the like is arranged so as to make a half turn around the outside of the hole 111h of the frame 41h.

In this embodiment, at the time of molding, the band-shaped part 2h is arranged in the longitudinal direction of the locking tool of the mold, and the IC chip part 4h is moved in the axial direction of the band-shaped part 2h from a position slightly shifted from the axis of the band-shaped part 2h. As shown in FIG. 21, the belt-like portion 2h is arranged so as to make a half turn around the outside of the hole 111h of the frame 41h. In this state, the frame 41h is sandwiched between the molds (pins on the mold forming the inner wall 113h) and the vertical position of the frame 41h (see FIG. 22) is determined, and then the mold cavity is filled with molten resin, A locking tool is obtained by protruding the molded product from the mold after cooling.
In addition, the support method by the resin part of the head 1h of the frame 41h is the same as that of the fifth embodiment.

Next, the RFID action by the IC chip portion 4h and the antenna portion 5h will be described.
The belt-like portion 2h of the locking device is a conductor 51h that acts as the antenna portion 5h. However, the conductor 51h is in contact with the frame 41h, and the conductor 51h is previously insulated as described above. Therefore, the gap between the conductor 51h and the frame 41h is only an interval of electrical insulation. Further, in the coupled state of the head portion 1h and the coupling portion 3h, there is no conductive material in the locking portion 11h in the head portion 1h, that is, the hole 111h, the fixed tooth 112h, and the inner wall 113h in the vicinity thereof. In the locked state (FIG. 22) of the locking mechanism Kh in which the belt-shaped portions 2h are locked with each other, the inside of the coupling portion 3h and the head 1h are electrically insulated. Therefore, the antenna portion 5h and the frame 41h are almost in contact with each other, and when the length of the band-like portion 2h is set to about ¼ of the wavelength of the UHF frequency, the antenna portion 5h is extremely effective in forming an electric field. It can play a role as a monopole antenna by obtaining special conditions.
In addition, the IC chip portion 4h also serves as a locking portion 11h of the head 1h and contributes to downsizing of the head 1h.

Next, an eighth embodiment will be described with reference to FIGS.
In this embodiment, the heads 1d of the locking devices of the above-described Embodiment 4 (FIGS. 9 to 14) are connected as shown in FIGS.
Therefore, since the shape of the head 1j and the arrangement of the IC chip portion 4j in the head 1j are different from those in the fourth embodiment, this point will be described.
In addition, since each other structure is the same as Example 4, description here is abbreviate | omitted.
23 to 25, the left and right locking tools are formed integrally with resin by connecting the heads 1j in a shape similar to a peanut shell shape in plan view, as shown in each figure.
The IC chip portion 4j is in the middle between the left and right holes 111j, and the frame 41j is positioned near the outer skin of each hole 111j and the head 1j.
Then, the portion excluding the non-antenna portions 52j of the inner wall 113j and each strip portion 2j of the locking tool, to form the antenna portion 5j performs the conductive film 51j subjected to evaporation such as a conductive metal described above Yes.

Thus it configuration was locking tool into 8 the shape of numbers as a result 27 to loop, each strip portion 2j to extend proximal the head 1j, despite non Antenna to loop Due to the presence of the portion 52j ( antenna outer end 53j), the two antenna portions 5j and the IC chip portion 4j are in an electrically coupled state, and the antenna portion 5j, in other words, the left and right loop-like belt-like portions 2j each have a longer communication distance. Plays the role of a dipole antenna . In this case, by approaching a part of the coupling portion 3j and the frame 41j that engages the head portion 1j also the IC chip portion 4j to so that such a magnetic coupling state binding unit, the two coupling portions 3j side of the antenna The part 5j and the IC chip part 4j are also electrically coupled (see FIG. 28).
As a result, arc angle of the antenna portion 5j of the extended base end side and the coupling portion 3j side of the head portion 1j of the strip-shaped portion 2j in a state close to 90 degrees when the loop-shaped strip-like portion 2j Combined with this, the entire antenna portion 5j serves as an antenna, thereby forming a cross dipole antenna.
If the IC chip portion 4j is arranged as shown in FIG. 26 and the conductive portion 51j is not present in the coupling portion 3j, the band-like portion 2j between the coupling portion 3j and the non-antenna portion 52j functions as an antenna. Since only the outer periphery of the head 1j and the antenna 54j of the band 2j between the non-antenna portion 52j and the head 1j serve as an antenna, the band 2j can be a dipole antenna. The range of choices can be expanded.

Next, a ninth embodiment will be described with reference to FIGS.
This embodiment is the same as the eighth embodiment except that the belt-like portion 2j of the eighth embodiment (FIGS. 23 to 29) is folded in half to form the belt-like portion 2k, and the non-antenna portion is the folded portion 52k.
Therefore, in addition to the same effects as in the eighth embodiment, the gap between the folded strips 2k can be reduced, and there are other tags that are likely to occur when products are stacked. There is also an effect that it is difficult to get entangled with the locking tool and the work becomes easier when packing or displaying the product.

In this embodiment, the heads 1f of the locking tool of the above-described embodiment 6 (FIGS. 16 to 20) are connected as shown in FIGS.
Therefore, since the shape of the head 1f and the arrangement of the IC chip portion 4f in the head 1f are different from those in the sixth embodiment, this point will be described.
In addition, since each other structure is the same as Example 6, description here is abbreviate | omitted.
32 to 35, the IC chip portion 4n is arranged in the postures shown in FIGS. 34 and 35 between the holes 111n of the left and right locking tools integrally formed by connecting the heads 1n to each other.
Conductor 51n is in the left coupling unit 3n, the left belt portion 2n and the left and right belt portion 2n street right head 1n, and one of the conductor 51n through to the right of the coupling portion 3n. At this time, in the head 1n, a part of the conductor 51n is disposed so as to avoid the left and right holes 111n and pass above the holes 111n as shown in FIGS. In the head 1n, the conductor 51n passes through the vicinity of the frame 41n of the IC chip portion 4n.

The belt-like portion 2n of the locking tool is a conductor 51n that acts as the antenna portion 5n, but in the coupled state of the head 1n and the coupling portion 3n, the locking portion 11n in the head 1n, that is, the hole 111n, in other words, For example, since there is no conductive material on the fixed teeth 112n and the inner wall 113n around the fixed teeth 112n, in the locked state (not shown) of the locking mechanism Kn in which the head 1n and the belt-shaped portion 2n are locked together, the coupling portion 3n and the inside of the head 1n are electrically insulated. Therefore, when the length of the band-like portion 2n is set to about ¼ of the wavelength of the UHF frequency, an effective condition for forming an electric field as the antenna portion 5n is obtained, and the role as a dipole antenna is achieved.
In the locking device of this embodiment, the conductor 51n of the belt-like portion 2n is made of metal, carbon fiber, stranded electric wire, or the like, so that long-distance communication is possible in addition to the effects described in the sixth embodiment. There is also.

In this embodiment (FIGS. 36 to 38), like the seventh embodiment (FIGS. 21 and 22), the IC chip portion 4p is a locking tool that also serves as the locking portion 11p of the head 1p. As in Example 10 (FIGS. 32 to 35), the heads are connected to each other.
The arrangement of the conductors 51p is the same as that of the tenth embodiment, and the IC chip portion 4p is different from the seventh embodiment. Therefore, the frame 41p of the IC chip portion 4p is a modification of the frame 41h of the seventh embodiment. The left and right holes 111p outside half circumference of the head 1p are also used as the frame 41p, and the left and right holes 111p inside half circumference are covered with a resin portion. Since other than that is the same as Example 7, description here is abbreviate | omitted.
Accordingly, in this embodiment, like the operation and effect of the seventh embodiment, the IC chip portion 4p also serves as the dipole antenna while being able to reduce the size of the head portion 1p by using the locking portion 11p of the head portion 1p. In other words, since the conductor 51p of the belt-like portion 2p is made of metal, carbon fiber, stranded wire, or the like, in addition to the effects described in the seventh embodiment, there is also an effect that enables long-distance communication.

In addition, as an Example common to Example 1- Example 11 demonstrated so far, as shown in FIG. 39, FIG. 40, each blade | wing 31 (a ˜p), a strain absorbing hole 31q as shown in FIG. 40 may be provided at the tip of the arrowhead. In this case, when passing the coupling portion 3q through each hole 111 (ap), the tip of the arrowhead-shaped tip is moved to the original position by passing through the flexible hole 111 (ap) due to the strain absorbing hole 31q effect. It is elastically restored to be coupled.
Accordingly, during the operation of attaching the fasteners to the product, the latches are usually taken out one by one from the group of fasteners. At this time, the other fasteners can be entangled and taken out together with the desired fasteners. Since there is no, there exists an effect which can perform the attachment operation | work of an efficient latching tool.

  41 and 42, a band-like part 2r in the form of a filament, and a band-like part 2r in which a locking mechanism kr that locks the belt-like part 2r on the opposite side of the head part 1r in cooperation with other articles are formed. Heads 1r of a plurality of locking tools formed by a horizontal bar 3r provided in a position crossing the belt-like part 2r at a portion opposite to the head 1r of the head and another article Gr through which the horizontal bar 3r passes. The antenna unit 5r is connected to each other, and the plurality of strips 2r are electrically connected to each other, and the horizontal bar 3r penetrates the other article G in a posture parallel to the strips 2r. A plurality of the horizontal bars 3r are passed through the other articles G at intervals so that the horizontal bar 3r intersects the belt-shaped part 2r again, so that the band-shaped part 2r and the horizontal bar 3r A mounting relationship was formed.

Then, as shown in FIG. 41, the IC chip portion 4r is resin-sealed in the head 1r with the posture shown in the figure.
In the locking device according to this embodiment, a loop is formed by the head 1r, the strip 2r, the horizontal bar 3r, and the other article G (see FIG. 42). In this case, if the other article G is, for example, clothing, etc., it is electrically insulated, so the space between the left and right horizontal bars 3r in FIG. 42 is a non-antenna portion.
Therefore, as in the other embodiments so far described, in the electric field, the IC chip portion 4r and the conductor 51r Ri Do electrically coupling relationship, the maximum voltage is induced at the position of the horizontal bar 3r resonant be Runode, the antenna portion 5r is serves as a dipole antenna.
As a result, in addition to the effect of extending the communication distance, using a widely used dedicated tool, the horizontal bar 3r is in parallel with the filament-shaped strip 2r and the article G such as a product is penetrated. When the horizontal bar 3r comes out of the article G, the horizontal bar 3r becomes in a posture to intersect with the belt-like portion 2r, and the horizontal bar 3r does not come out of the article G. Therefore, the locking tool can be easily attached to the article G. it can be the same handling as the current locking piece that, in other words, on which can perform the mounting work at very high speed, filamentary strip portion 2r is to play a role of dipole antenna.
Further, since the length of the non-antenna portion changes depending on the degree of the interval (see FIG. 42) between the locking positions of the horizontal bars 3r driven into other articles G, the communication distance changes as shown in Table 1. Can be made.
Therefore, since a desired communication distance according to the application can be easily obtained , an appropriate communication distance can be easily selected at the place where the locking tool is driven in accordance with each application. As a result, the exchange of information between the IC chip unit 4r and the system, for example, inventory, proper inventory management in the backyard, customer's interest in the product such as picking up the product, theft prevention, cash register work High-efficiency and high-efficiency work can be performed, such as various management such as simplification.
In this embodiment, the conductor 51r of the above embodiment is arranged as the antenna portion 5r. However, the same conductive film as described above may be used for a normal resin locking piece.
