ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention concerns a fixture of indication tag or the like having a magnetic body for marker for preventing commodities in a store or furnishings of public facilities or others from being taken away without leave.
2. Detailed Description of the Prior Art
Conventionally, a remote sensitive antitheft system has been used for preventing commodities in a store or furnishings of public facilities or others from being taken away without leave, wherein a bar code to be attached to a commodity or the like or a tag for indicating the price/quality is provided with a magnetic body for marker such as band plate piece using the magnetic reaction characteristic of a soft magnetic body to the alternating field thereof, and a sensing gate for generating the alternating field is disposed at the exit.
In the sensing system utilizing the magnetism, a magnetic body is used for marker of soft magnetic material presenting a high magnetic permeability and, a easiness of magnetization and demagnetization, such as amorphous metallic material. There, alternating field is generated by a magnetic field impression coil on the sensing gate side, a voltage pulse is generated in a detection coil (pickup coil) on the sensing gate side by the Barkhausen effect generated when the magnetization of the magnetic body for marker entered in the alternating field is inverted, and the presence/absence of the magnetic body for marker is detected without contact and remotely by detecting the voltage pulse.
Moreover, in the sensing system, after having passed through the cash desk or other regular root in a store where the magnetic body for marker is attached, if the magnetic body for marker remains detectable, the alarm sounds when passing through a similar sensing system of another store. Therefore, in order to prevent this, a deactivation (disabling) is performed to make the magnetic body for marker undetectable by the sensing system. Moreover, for the deactivation, a semi-rigid magnetic material is accompanied in practice with the magnetic body for marker of soft magnetic material.
The semi-rigid magnetic material is a magnetic material having a coercive force not as large as the permanent magnet material, but presenting a square hysteresis loop of a convenient size. In case where the semi-rigid magnetic material is not magnetized, the magnetic body for marker of the soft magnetic material deploys the Barkhausen effect by the alternating field, and is detected by the sensing system. However, in case where the semi-rigid magnetic material is magnetized by applying a high magnetic field, the magnetic force of the semi-rigid magnetic material interferes with the alternating field of the sensing system, making the detection impossible. Using this, the magnetic body for marker can be deactivated, by magnetizing the semi-rigid magnetic material, during the passage through a cash desk or other regular route.
Besides, a certain size or length is required for the magnetic body for marker to be detected at a distance, it is shaped in various forms such as strip, wire, foil, thin film, band plate piece, or others, applied to a sheet of paper, film or the like, and used as antitheft label and so on.
Then, the antitheft label is pasted to the commodity or others, and it is surveyed if the commodity is taken away without leave, by means of a sensing gate disposed at the exit of a store or the like.
However, in case where the magnetic body for marker is arranged at the back of the bar code, tag or others, the magnetic body for marker peels off easily, and does not perform the function thereof.
In addition, as the magnetic body for marker does not have the other functions, it is difficult to conceal and, hence, can be found easily; when the magnetic body for marker is found to be attached, it is cut off or pealed off, and can not accomplish effectively its antitheft function.
Especially, in order to prevent commodities in a store from being stolen, it is important to conceal the arrangement of the presence of the magnetic body for marker; therefore, it has been desired to develop materials having a magnetic body for marker whose presence would not be recognized at a first glance.
The Inventors of the present invention have proposed a security string provided with a soft magnetic material fiber that can be used for the application and the manufacturing method thereof in Japan Patent Application No. HEI 11-195919.
On the other hand, in order to attach an indication tag for indicating the price, quality or others to clothes displayed in a store, a method wherein, using an annular coupling device provided with an engagement male portion on one end of a filamentous coupling portion formed with elongated filaments or others of synthetic resin, and with an engagement female portion at the other end, the engagement male portion is passed through an through hole of the indication tag or others and an attachment hole such as button hole formed in the stuff or the like of garments or others and, thereafter, engaged with the engagement female portion to form a loop of the filamentous coupling portion, thereby attaching the indication tag of the like to the commodity or others, has been taken.
Moreover, a method using a hanger of indication tag or the like provided respectively with an engagement male portion and an engagement female portion at both ends of a filamentous coupling portion formed with elongated filaments or others of synthetic resin has been adapted. The hanger is provided with a holding portion to hold the indication tag or the like by engaging them, and a fitting portion of safety pin, loop forming body or others that can be fitted to a commodity such as garments or others, wherein the indication tag is held by the holding portion and fitted to the garments or others by the filling portion to hang the indication tag.
The filamentous coupling portion of these fixtures of indication tag or the like is formed so that the indication tag, once attached to a commodity such as garments, does not come off easily during handling, packaging or transportation and, in addition, can not be broken simply by hand operation.
SUMMARY OF THE INVENTION
The present invention devised in order to solve problems mentioned above and has an object to provide a fixture of indication tag or the like having a magnetic body for marker that can conceal the location of the magnetic body for marker and prevent it from being removed, by arranging secretly the magnetic body for marker, in a filamentous coupling portion for coupling an engagement male portion and an engagement female portion or in a filamentous coupling portion for coupling a holding portion and a fitting portion.
The fixture of indication tag or the like having a magnetic body for marker to achieve the object is configured as follows.
A fixture of indication tag or the like is formed by connecting an engagement male portion to one end side of a filamentous coupling portion and an engagement female portion to the other end side, and forming a loop by engaging the engagement male portion and the engagement female portion, wherein the filamentous coupling portion is formed with a filament having a soft magnetic material fiber.
According to the fixture of indication tag or the like formed by connecting the engagement male portion to one end side of the filamentous coupling portion and the engagement female portion to the other end side, an indication tag or the like can be attached simply to a commodity or others by forming a loop of the filamentous coupling portion, through engagement between the engagement male portion and the engagement female portion.
Otherwise, a fixture for hanging an indication tag or the like is configured, comprising a filamentous coupling portion, a crossbar portion joined to one end side of the filamentous coupling portion crossing with the filamentous coupling portion, and a head joined to the other end side of the filamentous coupling portion and at the same time formed larger than the cross-section are
