Description




FIELD OF THE INVENTION




The present invention is directed to a bracket for use in an article information display system, and more particularly, to a bracket for coupling a rail to a conventional shelf edge for use in an article information display system.




BACKGROUND OF THE INVENTION




Article information display systems are commonly used to provide variable information about various products. The system typically utilizes price tags having a variable display surface, such as an LCD (liquid crystal display) surface, to electronically display information about an associated, adjacent product. For example, price, price per unit weight, or other information may be displayed on the LCD display. A system controller controls the information displayed on a price tag. In this manner, the displayed information can be updated from a central location, and the controller can be coupled to the check-out scanners to ensure that the check-out price is consistent with the displayed price. Such article information display systems may be used in supermarkets, drug stores, grocery stores, hardware stores, auto parts stores, or other settings where variable article information is desired to be displayed.




In order to install such a display system, an auxiliary rail that is designed to receive and interact with an electronic display tag is mounted to conventional store shelves. Existing store shelves are preferably retrofitted to receive the auxiliary rail thereon. The auxiliary rail includes a conductor loop running along its length, and the electronic tag includes a coil extending around its periphery. When the electronic tag is mounted with the auxiliary rail, the conductor in the rail communicates with the coil in the tag by inductive coupling to convey information from the controller to the tag.




Various brackets and attachment means have been designed for attaching an auxiliary rail to an existing conventional shelf edge. For example, U.S. application Ser. No. 09/253,338 filed Feb. 19, 1999, hereby incorporated by reference, discloses various attachment brackets. The bracket of the present invention provides several advantages over the attachment methods.




SUMMARY OF THE INVENTION




The present invention is a bracket that enables the installation of auxiliary rails and other components of an electronic display tag system onto conventional, preexisting store shelving assemblies. The bracket does not require any structural modification to preexisting shelving assemblies, is quickly and easily mounted to the shelf edge using conventional hand tools, and does not require removal of products from the shelves. The bracket also includes one or more rail receiving portions, such as grooves, to facilitate the attachment of the bracket to the rail, the grooves receiving melted portions of the rail when the rail is attached to the bracket by heat staking. Furthermore, the bracket of the present invention is shaped to reduce detuning of the electronic tags that are received in the rail, thereby improving the operating characteristics of the display system.




In particular, the present invention is a bracket for coupling a rail having an upper slot and a lower slot to a shelf edge having an upper groove and a lower groove. The bracket comprises a central body portion, an upper flange extending generally upwardly from the body portion, a lower flange extending generally downwardly from the body portion, and a plate. The plate is received between the upper and the lower flanges such that as the plate is moved toward the body, the plate urges the upper flange and the lower flange into the upper and lower groove, respectively, to couple the bracket to the shelf edge. The bracket further comprises a first upper tang extending generally upwardly from the body portion and a first lower tang extending generally downwardly from the body portion, the upper tang and lower tang being shaped to be received in the upper and lower slot, respectively. At least one of the tangs has at least one rail receiving portion therein to facilitate the attachment of the bracket to the rail.




The present invention is also directed to a rail for receiving an electronic display tag therein and for being coupled to a bracket. The rail comprises a central body having a front surface and a rear surface, an upper finger extending from the front surface, and a lower finger extending from the front surface and spaced from the upper finger. The upper finger and the lower finger define a channel to receive an electronic display tag therein. The rail further comprises an upper lip extending from the rear surface and defining an upper slot for receiving an upper tang of a bracket therein, the upper lip being shaped to maintain the upper tang in the upper slot. The rail further includes a lower lip extending from the rear surface and defining a lower slot for receiving a lower tang of the bracket therein, the lower lip being shaped to maintain the lower tang is the lower slot.




Other objects and advantages of the present invention will be apparent from the following description, the accompanying drawings and the appended claims.

46


,


47


extending generally upwardly from the body


26


, and first and second lower tangs


48


,


49


extending generally downwardly from the body


26


. The tangs


46


,


47


,


48


,


49


are shaped to be received in the upper


16


and lower


18


slots of the rail


12


(FIG.

by heat staking, which entails heating the rail


12


and/or bracket


10


until portions of the rail


12


melt and conform around the bracket


10


, and allowing the melted portions to cool and harden. As shown in

FIGS. 1-2

, each tang

56


.

FIG. 6

illustrates an alternate embodiment of the rail


102


, and as shown in

FIG. 6

, a plurality of brackets


10


may be coupled to a single rail


102


(or a rail


12


) in the above-described manner. However, it should be understood that only a single bracket may be sufficient to couple a rail


12


,


102


to a shelf edge


14


. The bracket


10


may also be attached to the rail


12


,


102


by an adhesive. The brackets


10


are preferably coupled to the rail


12


before being shipped to the customer. In this manner, the preassembled rail/bracket combination reduces the installation time for the customer.




In order to couple the bracket/rail assembly to a shelf edge


14


, the brackets


10


are placed loosely into the shelf edge


14


such that the upper flange


28


of each bracket


10


is received in the upper groove


22


and the lower flange


30


is received in the lower groove


24


(FIG.


1


). The fastener


40


is then rotated to pull the plate


34


toward the body


26


of the bracket


10


(indicated by arrow A). The end surfaces


42


on the plate


34


engage the flanges


28


,


30


, thereby urging the flanges


28


,


30


into the grooves


22


,


24


(indicated by arrows B and C) until they are fixed within the grooves


22


,


24


by compression. The head


56


of the fastener


40


is preferably larger than the hole


38


in the body


26


such that the head


56


engages the body


26


during tightening to provide an opposing force during movement of the plate


34


in the direction of arrow A. A hole


58


is formed in the rail


12


to provide access to the head


56


of the fastener


40


, and the hole


58


is larger than the head


56


of the fastener


40


to allow the fastener to pass therethrough. After the rail/bracket combination is coupled to the shelf edge


14


, the hole may be covered


58


with any acceptable piece of sheet-like material, preferably an adhesive material that matches the color of the rail


12


. A generally cylindrical plug may also be received into the hole


58


.

FIG. 4

illustrates a rail


12


and shelf edge


14


after the rail


12


is attached to the shelf edge


14


.




In an alternate embodiment, the bracket


10


is of a two piece construction wherein the tangs


46


,


47


,


48


,


49


are made from a first piece of material, and the flanges


28


,


30


are made from a second piece of material. The second piece of material that includes the flanges


28


,


30


may be made from a thinner material, which provides more flexibility to the flanges, and is cheaper to manufacture. The first piece of material that includes the tangs


46


,


47


,


48


,


49


may be made from a relatively thicker piece of metal to provide robustness to the bracket


10


. The first piece and second pieces of material may be joined by a variety of conventional methods, including spot welding.




In yet another embodiment, the bracket


10


may include one or more holes in the tangs


46


,


47


,


48


,


49


. In this embodiment, when the tangs are heat staked to the rail, the melted portions of the rail


12


may flow through the holes formed in the tangs. Further alternately, dimpled or recessed portions may be formed in the tangs


46


,


47


,


48


,


49


to receive melted portions of the rail therein.




As shown in

FIG. 5

, the shape of the upper


46


,


47


and lower tangs


48


,


49


may be varied to change the display angle of the rail


12


and a display tag


60


. For example, the tangs may each include a generally horizontally extending section


62


and a generally vertically extending section


66


joined by an elbow


68


to vary the display angle. Thus, the bracket


10


of

FIG. 5

may be used on an upper shelf edge to angle the tag


60


downwardly for easier viewing and access. Similarly, an oppositely-angled bracket may be used to angle a rail and tag upwardly for use on a lower shelf edge. In the embodiment of

FIG. 5

, the end surfaces


42


of the plate


34


are both tapered to engage the flanges


28


,


30


.




As shown in

FIG. 5

, the rail


12


includes upper


72


and lower


70


channels for receiving a conductor


74


therein. The rail


12


receives a display tag


60


therein, and the tag


60


has a coil


76


extending around its periphery. The conductor


74


is used to transmit information and power to the coil


76


of the display tag


60


by means of inductive coupling. The coil


76


is electrically coupled to a capacitor, and the coil


76


and the capacitor are selected to resonate at a certain frequency, such as 50 kHz. It is known that the presence of conductive materials, such as metals, near the coil


76


may induce eddy currents in the coil


76


, which may change the inductance of the coil


76


. Thus, because the bracket


10


is preferably formed of metal, too much metal of the bracket


10


adjacent to the coil


76


can reduce the power delivered to the tag at the resonant frequency (i.e., “detune” the tag).




Accordingly, the bracket


10


is sized such that both of the vertical arms


50


,


51


cannot be adjacent the coil


76


at any one time. For example,

FIG. 3

illustrates the coil


76


of the tag


60


superimposed in hidden lines over the bracket


10


, the coil


76


having a pair of vertically-extending segments


80


,


80


′. It is seen that the vertical arms


50


,


51


of the bracket


10


are located such that if one of the vertical arms


50


is superimposed over one of the vertically-extending segments


80


of the coil


76


, the other vertical arm


51


is not superimposed over the other vertically-extending segment


80


′ of the coil


76


. In the illustrated embodiment, the horizontal distance D between the vertical arms


50


,


51


is smaller than the horizontal distance E between the vertical segments


80


,


80


′ of the tag coil


76


for the smallest tag


60


that is expected to be used in the system. In this manner, both of the arms


50


,


51


cannot simultaneously overlie the vertical segments


80


,


80


′ of the coil


76


, which helps to minimize detuning of the system. The vertical arms


50


,


51


also each include a cutout


84


to reduce the amount of metal that is located adjacent the vertical segments


80


,


80


′ of the tag coil


76


. Additional cutouts may also be located in the horizontally extending portions of the bracket


10


to further reduce interference between the bracket


10


and the coil


76


. The angling of the flanges


28


,


30


away from the body


26


also helps to reduce the detuning of the coil


76


.




When the rail


12


is mounted to the shelf edge


14


, it may be desired to provide a protective structure to prevent anyone from grabbing the top surface


88


of the rail


12


and pulling the rail


12


off the shelf edge


44


or bracket


10


. Accordingly, an alternate embodiment of the rail


102


shown in

FIG. 7

includes a cover


90


that extends generally rearwardly from a top surface


88


of the rail


12


to block access to the rear surface


20


of the rail


12


. The cover


90


blocks customers from wrapping a hand around the top surface


88


of the rail


12


to provide leverage for pulling the rail


12


off the shelf edge


14


. The cover


90


also blocks debris and other matter from falling behind the back of the rail


102


.




The rail


102


of

FIG. 7

includes a body


120


having a front surface


122


and a rear surface


124


. An upper finger


126


extends from the top surface


88


of the body


120


, and a lower finger


130


extends from the lower surface


132


of the body


120


. The fingers


126


,


130


are shaped and located to define a channel


131


that receives a tag


60


therein. An upper lip


110


extends generally rearwardly and downwardly from the rear surface


124


, and defines an upper slot


16


that receives the upper tangs


46


,


47


therein. A lower lip


112


extends generally rearwardly and upwardly from the rear surface


124


, and defines a lower slot


18


that receives the lower tangs


48


,


49


therein. The upper lip


110


and lower lip


112


extend downwardly and upwardly, respectively, along the rear surface


20


of the rail


102


for a significant distance, such that the lips


110


,


112


retain the upper tangs


46


,


47


and the lower tangs


48


,


49


of the bracket


10


therein. The lips


110


,


112


, preferably extend a distance of about 0.100 to about 0.150 inches. In this manner, the bracket


10


may be received in the rail


102


without any other attachment methods such as heat staking, adhesives, or the like.




As shown in

FIG. 6

, the rail


102


includes a raised protrusion


116


, said as a dimple or a swedge, on either side of the bracket


10


. The protrusions


116


extend generally outwardly from the rear surface


124


of the rail


102


to limit the lateral sliding of the brackets


10


within the rail


102


. In this manner, the spacing of the brackets


10


is maintained to provide uniform support, and the fastener


40


is maintained in alignment with the hole


38


in the rail


102


to ensure access to the fastener


40


. In the embodiment shown in

FIG. 7

, the rail


102


includes a pair of upper protrusions


123


that extends generally inwardly from the upper lip


110


and a pair of lower protrusions


125


that extend generally inwardly from the lower lip


112


. The set of upper protrusions are located on either side of the the tag


60


, as are the set of lower protrusions


125


. The upper


123


and lower


125


protrusions limit the lateral sliding of the bracket


10


in the rail. The protrusions


123


,


125


are preferably formed by swedging. Only a single pair of either upper


123


or lower


125


protrusion may be needed to block a single bracket


10


from sliding in the rail


102


, but both upper and lower sets are shown for illustrative purposes.




While the forms of the apparatus herein constitute a preferred embodiment of the invention, the present invention is not limited to the precise forms described herein, and changes may be made therein without departing from the scope of the invention.
