BEST MODE OF CARRYING OUT THE INVENTION

FIG. 1 depicts a dispensing unit 1 for the display and dispensing of merchandise items in accordance with a first embodiment of the present invention. Dispensing unit 1 is adapted to be supported or integral with a retail shelving system (not shown). Dispensing unit 1 comprises a base member 2, supporting a plurality of removable modular security dispensers 3 mounted in a side by side relationship. In this embodiment, the base member 2 may support up to eight modular dispensers 3.
Referring to FIGS. 2 to 6, each modular security dispenser 3 comprises an elongate housing 4 defining a track, a pivotal lid 5 and a removable automatic feed device 6. Elongate housing 4, which has a rear end 7 and a front delivery end 8, is for storing a plurality of merchandise items 9 in a row along the track. Automatic feed device 6 is used to forward feed merchandise items 9 towards front delivery end 8. A lower opening 10, being a narrow aperture in the delivery front end 8 of housing 4, allows for the foremost merchandise item 9 a to drop in a downward direction on to a ledge 26 to await removal from modular dispenser 3, as shown in FIG. 4. In this way, items 9 are removed from dispenser 3 in a downward direction. When merchandise item 9 a is removed from modular dispenser 3, automatic feed device 6 brings the next succeeding merchandise item 9 to the delivery front end 8.
In use, when a merchandise item 9 is removed from modular dispenser 3, and automatic feed device 6 brings the next succeeding merchandise item 9 to the delivery front end 8, it advances at a low uniform speed. “Low uniform speed” preferably means a speed that would take fifteen seconds or more to advance the next succeeding merchandise item to the delivery front end 8. By advancing at a low uniform speed, the automatic feed device 6 allows dispenser 3 to store and dispense merchandise items, whilst at the same time it eliminates the risk of a thief/shoplifter grabbing a plurality of many merchandise items in a single grab.
The automatic feed device 6 preferably comprises a spring loaded pusher assembly 15 similar to known automatic feed devices, one of which is shown in U.S. Pat. No. 4,300,693 (Spamer). Pusher assembly 15 is powered for the duration of its travel by a spring (bias) means (not shown) for advancing merchandise items 9 from the rear end 7 to the front delivery end 8. However, in this preferred embodiment a stop mechanism 20 engages with pusher assembly 15 to allow pusher assembly 15 to achieve its travel in a plurality of predetermined increments. Thus the automatic feed device 6 in combination with stop mechanism 20 form an “incremental feed device” which allows pusher assembly 15 to travel and push merchandise items 9 forward in a plurality of predetermined increments.
Stop mechanism 20 comprises a flexible elongate member 21 with two arrays (rows) of ramped projections (or teeth) 22 projecting therefrom. Only one of the arrays of ramped projections 22 is utilised at a time. In use, flexible elongate member 21 is disposed underneath the pusher assembly 15 and the advance of travel of pusher assembly 15 by spring means is prevented by engagement of a ramped lug 28, on the underside of and movable with pusher assembly 15, with one of the projections 22. An actuator having an engagable component, namely push-button 23, is operably connected to flexible elongate member 21. When push-button 23 is depressed, elongate member 21 is actuated by flexing, thereby disengaging a projection 22 from lug 28, which temporarily disengages stop mechanism 20 from pusher assembly 15. This allows pusher assembly 15 to travel in a predetermined increment until it abuts against an adjacent projection 22 next along in the array.
As a user must depress push-button 23 and await dispensing of an item 9 occurring by travel of pusher assembly 15 at a “low uniform speed” in a predetermined increment, and then remove the item 9 before again depressing the push-button 23 to dispense a further item 9, this will substantially act as a deterrent to a thief/shoplifter wishing to grab a plurality of items 9.
A user wishing to dispense a plurality of items 9 cannot continually keep push-button 23 depressed to rapidly dispense items 9. This is because of the location of push-button 23 on face 24 of dispenser 3, near opening 10 where item 9 is dispensed to ledge 26. Ledge 26 projects forwardly away from the bottom of face 24 such that face 24 is above ledge 26 and below feed device 6. When an item 9 a has dropped down on to ledge 26, push-button 23 on face 24 is behind item 9 a. In order for foremost item 9 a to be dispensed from opening 10, in a downward motion towards ledge 26, a user must take their hand away from push-button 23, after first depressing it to start the dispensing action, in order to not obstruct or hinder the dispensing action. As push-button 23 is depressed and released to dispense an item 9, this ensures that travel of pusher assembly 15 occurs in the earlier mentioned “predetermined increment”. Furthermore, the next dispensing action cannot be started until a dispensed item 9 a is removed from modular dispenser 3 because when the dispensed item 9 a is resting on ledge 26 it covers and blocks access to push-button 23.
A further security feature is that an item 9 being dispensed must pass through a one way opening hinged flap 27 located at the front delivery end 8, a short distance back from and above opening 10. Whilst an item 9 can push and move past flap 27 in a downward direction, it cannot be pushed open in an upward direction. As the opening 10 is narrow and flap 27 is disposed internally a short distance therefrom, a thief or shoplifter is prevented from easily accessing the items 9 within housing 4 via opening 10. Flap 27 is biased upwards by a spring (not shown) such that it is normally horizontal as shown in FIG. 3.
Referring to FIG. 1, a security member 11 is fixed to side walls 12 of base member 2, thereby preventing the easy removal of modular dispensers 3 from dispensing unit 1, and preventing lids 5 of dispensers 3 from being opened. However, security member 11 can be removed by a retail employee for filling dispensers 3 or for their removal and/or exchange. Whilst in this embodiment security member 11 is shown spanning across the top of dispensing units 3, it could in other embodiments be a lockable lower member spanning across the front of dispensing units 3.
From time to time, should merchandise items 9 get stuck in elongate housing 4 or automatic feed device 6 become stuck, the modular nature of each modular dispenser 3, its pivotal lid 5 and removable automatic feed device 6 means that faulty or jammed modular dispensers 3 can be readily removed from the dispensing unit 1 to be cleared, replaced and/or repaired. Therefore, the arrangement of dispensing unit 1 both acts as a deterrent to theft of retail items and allows for ease of maintenance.
As previously mentioned, whilst flexible elongate member 21 has two arrays (rows) of ramped projections (or teeth) 22 projecting therefrom, only one array of projections 22 is used at a time. The two arrays each have different spacing for projections 22, thereby allowing a flexible member 21 of stop mechanism 20 to be set up in a choice of travel increments, to suit different merchandise items to be dispensed, by moving ramped lug 28 sideways to engage the other array.
In a further enhanced security arrangement, RFID technology may be used in conjunction with dispensing unit 1 and dispensers 3 as shown in FIG. 7. Each merchandise item 9 would be provided with a passive RFID tag 30. An RFID reader 31 associated with a dispensing unit 1 30 or dispenser 3 would be located in close proximity thereto. The RFID reader 31 may operably be connected to an in-store security surveillance system 50 via a controller 32. The controller 32 may be separate or integral with the RFID reader 31. Should controller 32 detect that a plurality of items 9, which for example may be three or four items 9, are dispensed in a under a predetermined time interval the RFID controller may signal the in-store security surveillance system. This may include alerting in-store security staff to an incident of potential theft, and/or ensure that camera surveillance data is stored for the relevant time of the incident occurring.
FIG. 8 depicts a second embodiment of a dispensing unit 1 a for the display and dispensing of merchandise, in accordance with the present invention. Dispensing unit 1 a is similar to dispensing unit 1 shown in FIG. 1, except that its modular security dispensers 3 are mounted in a vertical arrangement in its base member 2 a. The dispensers 3 of dispensing unit 1 a are similar to those of dispensing unit 1. In this example, there a four vertically arranged dispensers 3.
FIG. 9 depicts a third embodiment of a dispensing unit 1 b for the display and dispensing of merchandise, in accordance with the present invention. Dispensing unit 1 b is similar to dispensing units 1 and 1 a, except that dispensing unit 1 b has its modular security dispensers 3 mounted both side by side and vertically in its base member 2 b. In this example, there are twelve dispensers 3 arranged in an array three wide by four high.
In the dispensing unit 1 of the first embodiment where a plurality of security dispensers 3 are arranged side by side, lockable pivotal lid 5 is used to prevent access to the internals of the housing of each security dispenser 3. In order clear, replace and/or repair the security dispensers, pivotal lid 5 must be raised from above. This arrangement may not suit certain retail environments where it is difficult to have pivotal lid 5 opened from above to gain access to a security dispensers 3. As such, for retail environments where the first embodiment is not suited due to restricted access from above, a fourth embodiment is proposed as follows.
FIGS. 10 to 15 depict a dispensing unit 100 for the display and dispensing of merchandise items in accordance with a fourth embodiment of the present invention. Dispensing unit 100 is adapted to be supported or integral with a retail shelving system (not shown). Dispensing unit 100 comprises a base member (hidden) and side walls 112, supporting a plurality of security dispensers 103 mounted in a side by side relationship. In the present embodiment, there are three security dispensers 103.
Each dispenser 103 like that of dispenser 3 of the first embodiment, is elongate and has a track and a removable automatic feed device 6.
Each dispenser 103, has a rear end 107 and a front delivery end 108, and is for storing a plurality of merchandise items in a row along the track. Automatic feed device 6 is used to forward feed merchandise items towards front delivery end 108. However unlike dispenser 3 of the first embodiment, each dispenser 103 does not have an elongate housing and pivotal lid. Instead, in the present embodiment each dispenser 103 is defined by its elongate track and automatic feed device 6 is flanked by either two partition walls 104, or a partition wall 104 and side wall 112.
In use, when a merchandise item is removed from dispenser 103, and its automatic feed device 6 brings the next succeeding merchandise item to delivery front end 108, it advances at a “low uniform speed” similar to the first embodiment. By advancing at a low uniform speed, the automatic feed device 6 allows dispenser 103 to store and dispense merchandise items, whilst at the same time it eliminates the risk of a thief/shoplifter grabbing a plurality of many merchandise items in a single grab.
Automatic feed device 6 preferably comprises a spring loaded pusher assembly 15 similar to the first embodiment. The fourth embodiment also utilises a stop mechanism and push button similar in function to that described and shown with reference to the first embodiment.
However the fourth embodiment differs from the first embodiment by the means by which internal access is made to the dispensing unit and dispensers by retail employees or maintenance staff. In the first embodiment as shown in FIGS. 1 and 2, each security dispenser 3 has its own housing 4, pivotal lid 5 and front delivery end 8. A security member 11 is fixed to side walls 12 of base member 2, thereby preventing the easy removal of modular dispensers 3 from dispensing unit 1, and preventing lids 5 of dispensers 3 from being opened. However, security member 11 can be removed by a retail employee for filling dispensers 3 or for their removal and/or exchange. Whilst security member 11 is shown spanning across the top of dispensing units 3, it is understood that alternatively a lockable lower member spanning across the front of dispensing units 3 could used.
Reverting now to the fourth embodiment, each dispenser 103 does not have an individual housing or pivotal lid. Instead, the dispensing unit 100 has a lockable pivotal front cover 130 which can be pivotally opened by a retail employee for filling dispensers 103 or for the removal and/or exchange of the component parts thereof. In addition to providing internal access to the dispensing unit 100, pivotal front cover 130 acts as “single wall member” for each of the delivery front ends 108 of dispensers 103.
Pivotal front cover 130 is preferably made of clear plastic material and pivots about rod 131, between a “closed configuration” and an “open configuration”. A locking mechanism 140 is used to lock the front cover 130 in the closed configuration.
Pivotal front cover 130 has two opposed side flanges 132. Each side flange 132 has slot 137, and the opposed free ends of rod 131 extend into a respective slot 137. Rod 131 is able to move or translate within the slots 137.
Each side flange 132 of front cover 130 has a projection 133 with a slot recess 134 there below. In the “closed configuration” each side flange 132 is lockably engaged with an associated upwardly projecting barb 135 in a respective side wall 112. Cover 130 is held in the “closed configuration” with barbs 135 inter-engaged with their respective recesses 134.
When in the “closed configuration”, and latch 147 of lock mechanism 140 is latched, cover 130 cannot be moved upwardly. However, when lock mechanism 140 is unlocked by turning knob 148 as shown by arrow A in FIG. 13, cover 130 can be pivotally opened, see arrow C in FIG. 15 to the open configuration.
From time to time, should merchandise items get stuck in any of dispensers 103 or their respective automatic feed devices 6 become stuck, pivotal front cover 130 may be opened so that the dispenser 100 may be cleared, replaced and/or repaired.
It should be understood that biased mechanism (not shown) may be used to bias cover 130 towards the closed configuration.
The terms “comprising” and “including” (and their grammatical variations) as used herein are used in an inclusive sense and not in the exclusive sense of “consisting only of”.
