Description

FIELD OF THE INVENTION

The invention relates to theft deterrent and security tags in general, and in particular to a disposable tag body containing an adjustable engaging element and having a an electronic marker comprised of, for purposes of illustration, either an electronic article surveillance (EAS) or for RFID device, or a combination of both.

BACKGROUND OF THE INVENTION

Various types of theft deterrent and article monitoring devices are known in the art. Electronic article surveillance (EAS) systems are known having the common feature of employing a marker or tag which is affixed to an article to be protected against theft, such as merchandise in a retail store. When a legitimate purchase of the article is made, the marker can either be removed from the article, or converted from an activated state to a deactivated state. Such systems employ a detection arrangement, commonly placed at all exits of a retail store, and if an activated marker passes through the detection system, it is discovered by the detection system and an alarm is triggered. In addition, other tags are known that utilize ink vials that break and release a permanent staining fluid onto the article if the tag is not removed by an authorized individual.

Existing devices do not address the need for an integrated security tag that is difficult to defeat and easy to use. In addition, the existing devices fail to provide a theft deterrent tag assembly that allows easy attachment of the lanyard to the tag. Therefore, there remains a long standing and continuing need for an advance in existing security devices and theft deterrent tags that makes the tags more difficult to defeat, simpler in both design and use, more economical and efficient in their construction and use, and provides a more secure engagement of the article.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to FIGS. 1 through 5, a tag body 20 is illustrated having a first section 22 and a second section 24. First and second sections 22 and 24 are preferably made of a hard or rigid material and are adapted to attach to one another and form a front end 21 and a rear end 23. A usable rigid or hard material might be a hard plastic such as, for purposes of illustration but not limitation, an injection molded ABS plastic or like material.

Second section 24 has a peripheral wall 26 extending inwardly from a second inner surface 28a of second section 24 and securely engaging first section 22. If a plastic material is used for the body of tag 20, the mating of peripheral wall 26 to first section 22 can be accomplished via an ultrasonic weld or like joining mechanism. However, it is to be understood that other joining methods known in the art, such as adhesives for example, may also be used. A first inner surface 28b of first section 22 and second inner surface 28a of second section 24 oppose one another and create a cavity 30 within which a marker 32 is enclosed. In one preferred embodiment, marker 32 may be attached to first inner surface 28b with an adhesive.

Marker 32 may be an Electronic Article Surveillance (“EAS”) device or any means known in the art for monitoring an article to which it is attached. Conventional EAS devices or tags include a resonator that, when activated, causes an alarm to sound when the EAS tag is brought within operative proximity of detection apparatus (which is typically located at the exit of a store). Marker 32 may also be a radio-frequency (“RFID”) device. RFID is a generic term for technologies that use radio waves to automatically identify objects such as tagged products. There are several conventional methods of identifying objects using RFID, the most common of which is to store a serial number (and other information if desired) that identifies the object on a microchip that is attached to an antenna. The chip and the antenna, together with any supporting substrate, herein are called an RFID device or an RFID tag. The antenna enables the chip to transmit the identification information to a reader. The reader converts the radio waves from the RFID device into a form that can then be utilized by a computer and read by a user. Marker 32 may also be any transponder or a combination of both an EAS and RFID device, and can also incorporate any later developed technology to track inventory or servile articles. Marker 32 is adapted to operate along the lines of a frequency modulated (FM) radio and also amplitude modulated (AM) radio signals.

An engaging element 34 has a first end 36 and a second end 38, at points distal to one another, and a middle region 40 therebetween. Engaging element 34 may be a lanyard preferably formed of stainless steel cable or like material that is flexible yet strong. A catch 42 is formed on second end 38 and is larger in diameter than the width of the engaging element 34. Catch 42 may be formed by creating a knot on second end 38 or catch 42 may be formed by crimping an anchor like device or metal element onto second end 38 or by soldering thereon. In addition, catch 42 may also preferably be formed by crimp splices.

A first aperture 44 and a second aperture 46 are defined through tag body 20. In one preferred embodiment, first 44 and second 46 apertures are defined through peripheral wall 26 proximal to front end 21. However, it is to be understood that apertures 44 and 46 may be formed through any portion of the tag body 20 without departing from the scope of the invention. First end 36 is fed through first aperture 44 from within tag body 20 and emanates from front end 21. However, as a result of the larger diameter of catch 42, it cannot pass through first aperture 44 and is securely maintained within attaching tag body 20. In a preferred embodiment, a first chamber 48 is defined within tag body 20 that is proximal to first aperture 44, such that catch 42 is maintained within first chamber 48 in a secure manner.

First end 36 of engaging element 34 is passed through an article to be monitored and first end 36 is inserted into second aperture 46. An attaching mechanism 50 is located within tag body 20 proximal to second aperture 46 and securely receives and maintains first end 36 therein. In such a state, the article to be monitored is maintained within a first loop 52 formed by engaging element 34. The article to be monitored may be of a wide range of sizes and the initial starting length of engaging element 34 may be of various predetermined lengths in order to accommodate the varying articles. However, despite the various predetermined starting lengths of engaging element 34, the size of first loop 52 may be adjusted after the insertion of first end 36 as a result of the dynamic attaching mechanism 50. For purposes of illustration, but not limitation, the article may be a baseball bat where engaging element 34 passes around the handle region of the bat and the engaging element 34 may be adjusted via attaching mechanism 50 such that first loop 52 tightens around the handle and it is maintained in a firm and snug manner by element 34.

Now also referring to FIGS. 6 through 10, a first path 54 extends inwardly from first aperture 44 and is defined by tag body 20. First path 54 may be defined by a pair of parallel walls extending inwardly from second inner surface 28a and enclosed by first inner surface 28b and second inner surface 28a. Attaching mechanism 50 is comprised of at least a first fastening member 56, but in a preferred embodiment it comprises a second fastening member 58, and a biasing member 60. Although in the preferred embodiment a coiled spring is illustrated as the biasing member 60, other resilient devices known in the art may be substituted therefor. A first retaining member 62 and a second retaining member 64 receive and movable maintain first fastening member 56 and second fastening member 58, respectively. First and second fastening members 56 and 58 have a first and second protrusion 66 and 68 respectively and first and second protrusions 66 and 68 serve as a base around which fastening member 56 and 58 rotate when held within first and second retaining members 62 and 64, respectively. First and second fastening members 56 and 58 have a first barrier 70 and a second barrier 72, respectively.

First barrier 70 has a first forward region 74 and a first rearward region 76 distal thereto. First forward region 74 may be substantially concave to allow passage of first end 36 there through, but it is sufficiently sized to prevent the withdrawal of engaging element 34. First protrusion 66 extends substantially perpendicular to the axis formed between first forward region 74 and first rearward region 76 and is located proximal to the first rearward region 76. Second barrier 72 has a second forward region 78 and a second rearward region 80 distal thereto. Second forward region 78 may be substantially concave to allow passage of first end 36 there through, but it is sufficiently sized to prevent the withdrawal of engaging element 34. Second protrusion 68 extends substantially perpendicular to the axis formed between second forward region 78 and second rearward region 80 and is located proximal to the second rearward region 80.

First retaining member 62 and second retaining member 64, in one preferred embodiment, are substantially “c” or “u” shaped, where the open region of each “c” or “u” faces the other as in a mirror image. In addition, a first wall 82 and a second wall structure 84 extend in height partially into the open region of each “c” or “u” structure such that first and second protrusions 66 and 68 are maintained within the circular region and the first and second barriers 70 and 72 rest upon first and second wall structures 82 and 84, respectively, and each barrier 70 and 72 is able to pivot within the opening of each “c” or “u” shape. First and second barriers 70 and 72 are arranged such that their first and second forward regions contact one another or are substantially proximal to one another when engaging element 34 is not engaged and the point of contact between the two is substantially aligned with first path 54.

Biasing member 60 is located on a side of first and second barriers 70 and 72 that is on the opposite side of first path 54, such that biasing member 60 forces first and second barriers 70 and 72 toward first path 54. When first end 36 is inserted through path 54, it contacts first and second barriers 70 and 72 at the first and second forward regions 74 and 78 respectively and forces biasing member 60 backwards such that first end 36 travels there between. When first end 36 is at rest, biasing member 60 forces first and second barriers 70 and 72 back toward first path 74 such that engaging element 34 is securely maintained between first and second forward regions 74 and 78 and cannot be withdrawn from within tag body 20. However, if a user wishes to tighten first loop 52, engaging element 34 may further be inserted into path 54 and travels between first and second barriers 70 and 72. When a sufficient grip is formed lanyard 34, first and second forward regions 74 and 78 prevent the withdrawal of engaging element 34.

In an alternate preferred embodiment, either the first fastening member 56 or the second fastening member 58 may be used without the need for the other. In such an arrangement, for example, the first forward region 74 and a first edge 75 defined by a wall on path 54 can maintain engaging element 34 there between without the need for the second fastening member 58. Alternatively, second fastening member 58 and a second edge 77 would perform a similar function without requiring the first fastening member 56.

A second path 86 is defined past biasing member 60 and receives first end 36 of engaging element 34 therein. First end 36 travels through second path 86 and out of tag body 20 via a third aperture 88 located distal to second aperture 46 and defined by tag body 20. The excess engaging element 34 that extends from third aperture 88 may either be left there or cut by a user as desired. It is to be understood that a plurality of attaching mechanisms 50 may be aligned to further strengthen the grip on engaging element 34.

Now also referring specifically to FIGS. 11 and 12, a tag body 20 is shown having an alternate preferred embodiment of having two engaging elements 34. This arrangement can be used to enclose boxes either in a retail store or during shipping to ensure that the contents of the boxes have not been tampered with. In this embodiment, all parts which are the same as or similar to corresponding parts in the embodiment of FIGS. 1 through 10 are noted with the same reference numerals, but followed by a letter (i.e. a through c). As illustrated, the tag body has four sets of attaching mechanisms 50, 50a, 50b, and 50c. However, it is to be understood that additional attaching mechanisms may be provided, preferably in alignment, to increase the grip on lanyard 34. In this alternate preferred embodiment, two engaging elements 34 and 34a (for example, but not limitation, a lanyard, cable, steel cable, straps, or the like) extend from first apertures 44 and 44a respectively and are received within second apertures 46 and 46a respectively such that two first loops 52 and 52a are formed. Apertures 44, 44a, 46, and 46a are arranged such that engaging elements 34 and 34a intersect one another to enclose an article to be monitored there between. In one preferred embodiment, engaging elements 34 and 34a intersect one another at substantially right angles in order to enclose an article there between.

Now referring specifically to FIGS. 13 to 18, an alternate preferred embodiment is illustrated wherein a holder 90 maintains engaging elements 34 and 34a adjustably therein. A marker 32 is maintained within the body 20. In a preferred embodiment, holder 90 has a first portion 92 to receive engaging element 34 and a second portion 94 to receive engaging element 34a. In the illustrated preferred embodiment, first portion 92 and second portion 94 are hollow passageways that allow the engaging elements 34 and 34a to travel there through. But it is to be understood that alternate methods of maintaining engaging elements 34 and 34a, such as resilient clips or other devices known in the art, may be substituted therefor. Although in the illustrated preferred embodiment the holder 90 provides substantially perpendicular crossing of the engaging elements 34 and 34a, it is to be understood that a wide range of alternate angles, and even parallel alignment, are possible without departing from the essence of the invention.

The preferred embodiment illustrated in FIGS. 11 to 18 can be provided to an end user with engaging elements 34 and 34a partially placed within first 44 and second 46 apertures, respectively. The end use places an article to be monitored within the engaging elements 34 and 34a and can pull the first ends 36 and 36a to firmly secure the engaging elements 34 and 34a around the object. These steps are illustrated more particularly in FIGS. 16 through 18. In one preferred embodiment where a holder 90 is used, when an article is engaged by the tag body 90 and engaging elements 34 and 34a, holder 90 will be substantially located on a distal and opposing side in relation to tag body 90.

While the above description contains many specificities, these should not be construed as limitations on the scope of the invention, but rather as an exemplification of preferred embodiments thereof. Many other variations are possible without departing from the essential spirit of the preferred embodiments of this invention. Accordingly, the scope of the invention should be determined not by the preferred embodiments illustrated, but by the claims and their legal equivalents.
