DETAILED DESCRIPTION OF THE INVENTION
The merchandise security display bag of the present invention is indicated generally at 1, and is shown in FIGS. 1 and 2 mounted on a usual type of display rod 3. However, it is readily understood that bag 1 could be displayed in various manners other than rod 3 and can contain various items of merchandise. Bag 1 includes as its main component a mesh bag indicated generally at 5, preferably formed of metal wire strands 7 which may be connected together by clips, ferrules or other types of fasteners 9 to form a bag-like structure having a closed bottom end 11 and an open top end 13. Metal wires 7 preferably are coated with a plastic material and can be of various thicknesses and types of metal or other materials which are cut resistant without affecting the concept of the present invention. Furthermore, the size of the void areas 15 between the adjacent metal wires 7 can vary depending on the type and size of merchandise 17 to be stored therein. A pair of boxing gloves is shown in FIGS. 1 and 2 and is merely an example of the numerous types of merchandise that can be stored within internal storage chamber 19 provided by mesh bag 5. It is also understood that mesh bag 1 could be formed of other materials than metal wire so long as it prevents or greatly retards cutting of the material.
In further accordance with another feature of the invention, a locking device indicated generally at 21, closes open top end 13 of the bag to secure merchandise 17 in chamber 19. Locking device 21 includes first and second locking members 23 and 25, respectively. Each of the locking members has a generally elongated configuration as shown in FIG. 1 and is adapted to be permanently connected to closed loop ends 27 and 29, respectively, at the peripheral edge of top opening 13, as shown particularly in FIGS. 5 and 6 and discussed in further detail below. Thus locking members 23 and 25 are permanently attached to the peripheral edge of bag opening 13 by the closed loop ends of the bag and remain permanently on the bag with each of the locking members extending across approximately one side of the peripheral edge of the open bag end. Members 23 and 25 preferably have a length “L” approximately four times the width “W”. This provides for a compact structure while providing the bag opening 13 to be as large as possible.
First locking member 23 is shown in an exploded condition in FIG. 7 and includes two main components, a housing 31 and housing cover plate 33. Housing 31 has a generally elongated rectangular configuration with a lower edge 35 formed with a plurality of arcuate slots 37 for receiving the closed loop ends 27 of mesh bag 5. A generally rectangular-shaped recess 39 is formed in an upper portion of housing 31 adjacent top edge 83 for receiving a spring locking strip indicated generally at 43. Spring strip 43 includes a central hole 45 for receiving a positioning pin 47 therethrough for positioning the spring strip within recess 39. Spring strip 43 includes a pair of locking tines 49 which are biased to extend outwardly from the strip as shown in FIG. 7A. Each of the locking tines has an elongated configuration with a distal end 51 and opposed elongated edges 53. Elongated edges 53 preferably are two to three times greater than the width of distal end 51 to provide increased locking strength as discussed below.
Housing cover plate 33 includes a rectangular-shaped rib 55 which abuts against spring strip 43 as shown in FIG. 9A, to maintain the spring strip within recess 39 of housing 31. A plurality of positioning pins 56 preferably are formed on housing cover plate 33 and extend into positioning holes 58 formed in peripheral edge 35 of housing 31 to properly align and position cover plate 33 on housing 31 prior to permanently connecting the two members together by ultrasonic welding, an adhesive or other types of securing means. Joined members 31 and 33 trap locking strip 43 permanently within recess 39 which communicates with an interior locking chamber 54 formed in locking member 23.
Second locking member 25 is shown in detail in FIGS. 5, 6 and 8 and includes a main housing 57 and a cover plate 59 which is permanently secured to housing 57 by ultrasonic welding, an adhesive or other securement means as shown in FIG. 6 forming a hollow interior 60. Aligned arcuate slots 61 and 63 are formed in housing 57 and cover plate 59, respectively, for trapping the closed loop ends 29 of mesh bag 5, as shown particularly in FIG. 6. A pair of alignment tabs 65 are formed on housing 57 and are slidably received in slots 67 formed in housing 31 to assist in locking member 25 to member 23 as shown in FIGS. 10 and 11.
Preferably, an EAS tag 69 or other type of alarm activation device is permanently secured within chamber 60 as shown in FIG. 6 for activating an exit alarm gate at a retail establishment should a thief attempt to take the entire security bag 1 in an unauthorized manner through the exit gate. As discussed above, a plurality of closed loop ends 29 extending approximately across one-half the periphery of open bag end 13 are secured within arcuate slots 61 and 63 for permanently attaching second locking member 25 to mesh bag 5.
The manner of use of locking device 21 is best shown in FIGS. 9-15. After an item of merchandise 17 has been placed in storage chamber 19 through top end opening 13, locking member 25 is moved in the direction of arrow A, FIG. 9, into the interior chamber 54 of locking member 23. Ramped surfaces 71 (FIG. 10) formed on a locking projection 73 provided on the top edge of housing 57 engage extended locking tines 49 and depresses them inwardly as shown by arrow B, FIG. 10, until locking member 25 is completely inserted into chamber 54 of locking member 23 as shown in FIG. 11. In this position locking tines 49 will move outwardly into the locking position as shown in FIG. 11 where they engage an undercut surface 74 of locking projection 73 to prevent locking member 25 from moving in an unlocking direction, opposite to the locking direction as shown by arrow C in FIG. 10. Since tines 49 are spring biased in an outward direction, they automatically lock members 23 and 25 together when member 25 is slidably inserted into lock chamber 54 of member 23 eliminating additional time and effort to secure the merchandise in a secure locked condition.
In accordance with another of the features of the invention, elongated edges 53 of locking tines 49 engage locking projection surfaces 74 to prevent movement of locking member 25 out of locking engagement with locking member 23 providing a relatively large area to resist any forceful separation of housing members 23 and 25. Heretofore, when similar locking tines have been used in a locking device, only the distal ends 51 are engaged by locking projections. This could result in the tines being buckled and snapped out of place if a sufficiently large force is exerted on the locking members. Again, edges 53 are at least twice, and preferably three times the width of distal end 51.
To unlock locking device 21, a magnetic key 75 preferably containing a pair of magnets 77 (FIGS. 13 and 14), is placed in close proximity to locking strip 43 and magnetically attract tines 49 to move them from the locked position of FIG. 12 to the unlocked position of FIG. 14. This enables inner housing 25 to be moved in the direction of arrow D (FIG. 15) to the unlocked position permitting locking members 23 and 25 to be separated as shown in FIG. 9. Bag opening 13 can be spread apart for removal of the stored merchandise. Key 75 preferably has one of more positioning tabs 79 for placement in notches 81 which are formed in the top peripheral edge 83 of housing 31, as shown in FIGS. 1 and 7. This insures that key magnets 77 are properly aligned with tines 49 in order to retract the tines to the unlocked position.
The unique merchandise security display bag of the present invention provides a relatively simple and inexpensive device in which the mesh bag preferably is formed of metal wire or other types of material which is not readily cut or pulled apart by a potential thief. The bag enables a merchant to store various shapes of objects in a secure protected manner and enables a prospective purchaser to readily see the items stored therein. The merchandise is secured in a locked position by locking device 21 which is comprised of two plastic components, except for internal spring strip 43. This enables the locking device to be mass produced relatively inexpensively, with each of the components being comprised of two members which when secured together by an ultrasonic weld, an adhesive, etc. will trap the closed loop ends of approximately one-half of the bag end opening periphery in each of the locking members. This enables the locking members to be retained permanently on the bag and provides a convenient manner for enlarging the open top end 13 of the bag for placement and removal of the items of merchandise into and from storage chamber 19.
The lock device 21 is easily snapped into a locked position by slidably inserting locking member 25 into lock chamber 54 of locking member 23. Device 21 is easily opened by use of magnetic key 75. Mesh bag 5 can be formed in various sizes of mesh and can safely store various items of merchandise. For example, a number of blister or bubble packs can be contained within bag 5 and supported on rods 3 by mounting holes formed in the inner packages and then removed by store personnel when needed for individual placement on the support rods. The mesh bag can be produced very inexpensively as well as plastic locking members 23 and 25.
