DETAILED DESCRIPTION OF THE INVENTION
Reference is made to the accompanying drawings which show a control tag in accordance with the invention, both in complete views and as exploded views of the invention. The exploded views of the invention show the internal components and operation of the control tag and its structural characteristics which facilitate appropriate engagement and disengagement of the upper and lower parts.
The micro shell alarming ink tag is designed to provide multiple anti-theft measures in a single unit, preferably including both ink and alarm protection. The control tag of the invention incorporates and is based upon the standard 3-ball clutch mechanism structure and preferably includes a 58 Khz and/or 8.2 Mhz ferrite member. The tag ferrite will be energized by an electronic article surveillance (EAS) system that preferably generates a 58 Khz or 8.2 Mhz magnetic field respectively, and subsequently generate its own 58 Khz or 8.2 Mhz signal that will be detected by EAS detection systems. An alarm will thus be activated when the product to which the control tag is attached passes through an EAS detector arrangement.
In addition, tampering with the control tag or attempting to remove it from the article to which it is attached will cause a sealed ink reservoir contained within the tag to break or fracture, thereby releasing the ink within. The result is the permanent staining the article with the released ink. At the same time, the article is branded with a clear visible marking so that it is immediately recognizable as one which may have been stolen or unlawfully obtained. Furthermore, the released ink from the reservoir may also have the consequence of effectively ruining the article, such as an electronic device or an item of clothing, so that the article becomes worthless to the person trying to steal it.
As will be seen from the drawings, and best illustrated in FIG. 5 of the drawings, the control tag 10 is comprised of an upper half shell assembly 12 and a lower half shell assembly 14. The upper half shell assembly 12 of the control tag 10 has a top shell cap 16 which is generally dome shaped and has a central opening 18 which receives a reservoir protection cap 20. The outer surface of the top shell cap 16 may have ribs 22 to facilitate improved grip capacity when held by a user.
The lower half shell assembly 14 comprises a base member 24 which defines an open chamber 26 and a cover 28 which fits over the base member 24 so as to close the chamber 26. A suitable form of connection between the base member 24 and the cover 28 along their respective common circumferences is provided to ensure a positive seal there between.
The base member 24 has a base wall 30 and a side wall 32. Formed on the base wall 30 is generally cylindrical cup 34 which is hollow and has an opening 36. The cup 34 receives a three ball clutch 36 of generally known construction in the art, the clutch being designed to receive and hold a pin by the pressure of the balls thereon. The pin, to be briefly described below, can be removed from the clutch 36 when the balls are appropriately subjected to the forces of a magnet strong enough to move the balls off the pin, thereby disengaging the pin and allowing for the release thereof from the control tag 10.
The cover 28 has a generally dome shaped portion 40 and a flat top 42, the flat top 42 having a substantially centered hole 44 through which the pin shaft passes in order to engage the clutch 36. The inner surface of the cover 28 has one or more projections 46 which cooperate with the cup 34 so that the clutch 36 can be held in place when the cover 28 is mounted on the base member 24.
A pin assembly 50 is provided. The pin assembly 50 comprises a support head 52 and a pin shaft 54. The pin shaft 54 itself has a pointed end 56 and a connected end 58 where is it permanently fastened to the support head 52. It will be seen that the pin shaft 54 has a textured or roughened surface and this enhances its ability to effectively be captured by the balls in the clutch 36.
The support head 52 has a lower surface 60 which generally overlies the flat top 42. The pin shaft 54 passes through the hole 44 into the chamber 26. In the chamber 26, the pin shaft 54 will be received by the clutch 36 located in the cup 34. Biasing means (not shown) urge the balls to engage the pin shaft 54 and hold it in a fixed or locked position until the balls are moved apart by a magnet (not shown). This is the conventional known operation of the three ball clutch used in control tags.
The support head 52 of the pin assembly 50 is fixed to the top shell cap 16. The support head 52 has an upper surface 64 which has configured therein a recess 70 which holds either ink or an ink filled capsule. The top surface 64 of the support head 52 can be accessed through the opening 18, which itself can be opened and sealed by the reservoir protection cap 20, as described above.
A reservoir plug 68 is provided to seal the ink reservoir formed by the recess 70.
The control is multiple alarm system for keeping track of inventory and preventing the theft thereof. Unauthorized tampering of an article and attempts to remove the control tag 10 from an article will provide alerts to store personnel.
The upper half shell assembly 12 with the attached pin assembly 50 and pin shaft 54 is, in use, pushed through the retail article or product such as an item of clothing, linen or the like. The point 56 and the pin shaft 54 pass through the hole 44 where it will be firmly gripped and held in place by the 3-ball clutch 36 mechanism structure as described above, at the same time sandwiching the product between the upper half shell assembly 12 and the lower half shell assembly 14 so that the product can only be removed by appropriate methods, such as the use of a specially designed magnet to pry apart the balls, as has been described. The proper mechanism for extracting of the upper half shell assembly 12 from the lower half shell assembly 14 without triggering alarms requires that the control tag alarming ink tag be placed on a super lock or sufficiently powerful magnetic detacher. The magnetic detacher will cause the 3 balls to move away from each other under the strong magnetic force to thereby release tension on the pin shaft 54, allowing the upper half shell assembly 12 to be extracted from the pin hole 44 of the lower half shell assembly 14 easily and without fracturing the ink reservoir to effectively ruin the article.
If any attempt is made at pulling the upper and lower halves apart by force, or prying the two halves apart, the pin shaft 54 will break away from the ink reservoir fracturing the ink chamber, and allowing ink to flow out beneath the top shell case, permanently staining the article. The control tag 10 is designed so as to have sufficient strength to withstand normal operating forces and not fracture under such conditions. However, when the force due to tampering exceeds this threshold value, the ink reservoir will fracture and discharge ink over the product rendering it useless for the person attempting to steal the product but also identifiable for store personnel as the target of a theft.
If the control tag is not removed from the product and there is no fracturing of the ink reservoir, the ferrite or other material contained in the chamber 26 will be energized by the electronic surveillance system located usually at the door or exit of the store and the sound alarm will be triggered.
The control tag 10 of the invention thus has a double alarm system, the one backing up the other so that if one is not activated during the course of an attempted theft, the other will be. The control tag of the invention thus addresses in a single device both the ability to trigger an electronic surveillance system at the door or exit of a store and also foil any efforts by a person to defeat the electronic surveillance system by ensuring that any effort to remove the tag will fracture the ink reservoir and thus deposit a large ink stain on the product to make the article essentially worthless. The article of the invention is thus very useful and addresses a void in the control of inventory and the theft of articles from a store. It should also be noted that even if a theft occurs and the thief manages to remove the tagged article from the store, the control tag is constructed to make its removal without the necessary tools very difficult and any subsequent efforts to remove the control tag with ruin the product. This fact in itself may act as a deterrence to the theft in the first place, adding to its value.
The invention is not limited to the precise details described herein. The essence of one aspect of the invention is the provision of a control tag which has built into it both an electronic trigger system to activate a sensor and alarm and thereby thwart its removal from a location, as well as a reservoir for a substance such as an ink or dye of some description which would color the article, either at the location or after it has been removed from the location, to which it is attached, preferably permanently, to thereby ruin the article for the purpose for which it was made.
In view of the above, the control tag of the invention will have a receptacle of any convenient shape or size which includes at least one chamber or space which accommodates both the electronics for activating an external sensor and alarm as well as a frangible reservoir for an ink or dye. The control tag will have two components which clamp together in some fashion at the same time holding the article or inventory there between in a fixed manner which is difficult to disconnect without specially designed tools such as a magnetic detacher. The shape of the control tag can be configured to selected dimensions so as to be somewhat flat, square, circular or other format so suit the application or context in which it will be used.
The control may have desired form of electronics, many of which are in use with conventional tags.
The reservoir may be constructed as part of the control tag itself, or it may be an add-in, and comprise a frangible container for the ink or dye which is received within a recess or space in the control tag specially designed therefor. The reservoir may be located and operate so that when it breaks as a result of unauthorized tampering, the ink or dye not only floods the article, but also contacts the fingers or hand of the person who is tampering with the product so as to identify that person as one who has tried to remove a control tag. Where the control tag uses frangible containers, these may be removable so that they can be replaced without the need to discard the entire control tag if the containers become weakened. Different color inks and dyes may be used for, as an example, inventory control and department identification.
Preferably, the two components of the control tag are fastened together using a pin mechanism on one of the components which is received in a slot three ball clutch arrangement as generally described above. However, it should be appreciated that any suitable form of connection may be used that will satisfy the requirements of the control tag and keep the components fastened to each other on a manner which will defeat all but the more sophisticated attempts to pry them apart.
