     BACKGROUND OF THE INVENTION 
     1. Field of the Present Disclosure 
     This disclosure relates generally to merchandise dispensing machines such as soda, coffee, cigarette and candy machines, and more particularly to a dispending machine for retail venues where large-scale theft of merchandises displayed on open shelves is problematic. 
     2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98 
     The references to Hardy, et al described below present a well rounded background of the subject matter of the present invention and of the serious need, that is, the motivation to establish an advanced merchandise product dispenser for retail stores. Product dispensing machines, i.e., vending machines, are very well known and up until the present have been designed for storing products of all kinds and for dispensing such products to consumers in exchange for currency without vendor attention. Vending machines are essentially vaults which store inserted currency and products for sale. As such they are expensive to provide and to operate and are not easy to use for all types of products. Recently, retail stores that traditionally display products on open shelves have experienced product theft by “sweeping,” a technique used by thieves wherein products for sale that are displayed on open shelves are swept, using an arm motion moving over the shelf to push a large quantity of product into waiting bags. Often these products do not have significant value, but will provide income to the thief upon resale in a gray or black market. A new generation of merchandise dispensing machines, represented by the following prior art has been developed to specifically deal with the theft of items which are displayed on open shelves. Such machines dispense products in a similar manner as coin operated vending machines, but without the need for the consumer to place currency in the machine to operate it. Its primary purpose is to thwart theft. 
     Hardy, et al., U.S. 2005/0161420, discloses a system for managing and securing product and deterring theft in a retail setting that includes a system that resides either on a standard retailer shelf or may be a stand-alone system. In an embodiment, the system includes a plurality of shelves and product dividers positioned between the shelves and extending from the front edges of the shelves toward the rear of the shelves. Front retaining walls are positioned at the front edges of the shelves and are configured to have a height that inhibits access to products on the shelves. Individual retaining tabs of varying height may be added in front of rows of taller product to inhibit access to these products. In an embodiment, rigid or moveable barriers may be positioned above retaining walls that further restrict access to the products. With the invention, the “sweeping” of numerous products by a thief is deterred. In another embodiment, an alert device may be configured to detect and monitor movement of the moveable barriers and may provide an alert signal corresponding to the management of product on the shelf or corresponding to a potential theft situation. In an embodiment, the alert device may communicate with a security camera to monitor the vicinity and provide a notification to the potential thief that his actions are being monitored and recorded, or provide a notification to store computer, pager, cellular telephone, or the like.

The first panel portion and the front panel substantially abut one another when the compartment is emptied of products and the first panel portion and the rear panel substantially abut one another when the compartment is filled with products. The follower is guided along the bottom panel by a guide member which extends from the follower into a slot in the bottom panel. Such guide member has a mechanism for modifying its width to compensate for slot/guide member wear. Vertically adjacent compartments are staggered so that substantially the entirety of at least the lower compartment is readily visible. 
     Rabas, U.S. Pat. No. 5,855,281, discloses a product display system which includes a basic unit including a track, a front wall, a back wall and a side member. The basic unit is easily assembled and disassembled. Two or more basic units can be ganged together to created customized displays to accommodate a wide varies of products of various sizes. 
     Hardy, U.S. Pat. No. 6,041,720, discloses a system for organizing and displaying items on a gondola shelf system comprising a gondola shelf connected to at least one vertical upright, the shelf including a front and a rear portion, a rail extending along and affixed to the front portion of the shelf, the rail comprising, a rail shelf surface extending longitudinally along the front portion of the shelf, the rail shelf surface including a first tongue extending from the rail shelf surface; a rail groove surface extending substantially perpendicular from the rail shelf surface, the rail groove surface including a first groove extending along the groove surface; and a display apparatus slidably engaged with the front rail, the display apparatus comprising a second tongue and a second groove, the first tongue engaging the first groove and the second tongue engaging the second groove. 
     Nagel, U.S. Pat. No. 6,745,906, discloses an adjustable width product display system that is comprised of a wire rack for supporting display products. At each end of the rack is a molded plastic base member having an upwardly opening recess for the reception of a cross bar element of the product support rack. Each base element is also provided with a pair of downwardly opening grooves of partially circular cross section, for the adjustable reception of transverse base elements of wire side supports. The side supports can be adjustably positioned to accommodate display product of various width. In many cases, a spring driven pusher sled may be provided on the display rack, and the base members are formed with one or more slots for the reception and anchoring of the free end of one or more pusher springs for driving the sled. The plastic base members are designed to accommodate vertical snap-in assembly of the rack and side supports into their respective grooves, to facilitate assembly. The base members are easily modified to include tongue-like extensions, enabling base members to be snapped onto guide strips provided at the front of display shelving, and also to be supported between front and back support rails, for example in a freezer display environment. 
     Caterinacci, U.S. Pat. No. 6,749,071, discloses a merchandise display device for dispensing and displaying digital media cases. Digital media cases are inserted vertically into the opening between the front panel and the lateral supports. This opening limits the number of cases which can be removed and/or inserted at one time. The width of the opening allows only two cases to be inserted or removed at a time, to deter theft. The opening, however, still allows for easy access when removing or inserting the cases. A replaceable pusher is attached to the back wall of the unit to bias the digital media cases toward the front panel. The display units are broken into two separate components, a right and left side. The components allow for flexibility in arranging the display system, depending on the need of the vendor. The invention provides a storage display system which continuously maintains the organized orientation of digital media cases, displays the covers of these cases, permits easy access and use of the stored objects and allows for flexibility so that the storage units are easy to install, reconfigure, and remove. 
     Thalenfeld, U.S. Pat. No. 6,769,552, discloses a product pusher device comprising an elongated guide track and a pusher sled slidably guided along the track for urging product packages forward on a display shelf. The pusher sled incorporates a housing for containing a coiled strip spring element. The end extremity of the spring is anchored at the forward end of the guide track, and the coiled body spring is confined within the housing at the back of the sled. By constructing the sled housing with an open bottom, assembly is greatly facilitated by allowing the spring to be anchored on the guide track independently of the sled and thereafter allowing the sled to be lowered over the coiled body of the spring and pressed downward to be snapped into assembled position on the guide track. 
     Hardy, WO02091885, discloses an integrated “T” assembly ( 500 ) combined into a single integrated assembly, a track portion along both sides of a divider. The T assembly may have a wide-base portion, which may include a spring-urged-pusher track, on one side of the divider and a narrow-base portion on the opposite side of the divider. An offset pusher may have an upper portion that is offset, via an angled offset portion, from a lower portion of the pusher. Additional supporting bases, any of which may include spring-urged-pusher tracks and/or a spring-urged pusher, may be used under a wide product. Left and right side finisher components may be paired with T assemblies near the sides of a merchandise-display shelf. The T assembly, base, and/or end finishers may be coupled to a front rail via a complimentary tongue and groove arrangement and/or a non-slidable engagement, such as mating teeth. 
     BRIEF SUMMARY OF THE INVENTION 
     This disclosure teaches certain benefits in construction and use which give rise to the objectives described below. 
     The present invention is a dispensing machine which includes an enclosure with a front door which may be opened for removing merchandise. The enclosure may be wall mounted or may be mounted to a surface as a stand-alone apparatus. Within the enclosure are mounted several merchandise supporting modules selectively engaged with selected slots of a shelf that is capable of being rolled out of the enclosure for loading the modules with merchandise boxes. The boxes are aligned on top of the modules in single file with a spring loaded pusher pressing on the last box in the line so that all of the boxes are pushed toward the front of the shelf and the enclosure. The first box in the line on each module may be ejected from the line of boxes by turning a knob at the front of the machine. When the knob is rotated it rotates a crank that raises a slide that pushes against the bottom of the first box thereby allowing it to jump over a barrier and fall to the front of the machine. The customer may then reach through a door to retrieve the box. When the door is opened it lowers a barrier strip so that the customer cannot reach into the modules and remove another of the boxes. The knob is fitted for making a loud noise so that retail store personnel are able to hear the ejection of products. If repetitive ejection noises are heard, this is an alarm to store personnel that a customer may be trying to defeat the system and may be a thief. 
     A primary objective inherent in the above described apparatus and method of use is to provide advantages not taught by the prior art. 
     Another objective is to provide a merchandise dispenser that prevents product theft by enclosing products within an enclosure. 
     A further objective is to provide such a dispenser with an adjustment feature that accommodates merchandise of various widths. 
     A still further objective is to provide such a dispenser with interlock for blocking stored merchandise when a dispensed item is made accessible to a consumer. 
     A still further objective is to provide such a dispenser that causes a tell-tail noise when an item is being dispensed. 
     Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the presently described apparatus and method of its use.

     DETAILED DESCRIPTION OF THE INVENTION 
     The above described drawing figures illustrate the described apparatus and its method of use in at least one of its preferred, best mode embodiment, which is further defined in detail in the following description. Those having ordinary skill in the art may be able to make alterations and modifications to what is described herein without departing from its spirit and scope. Therefore, it must be understood that what is illustrated is set forth only for the purposes of example and that it should not be taken as a limitation in the scope of the present apparatus and method of use. 
     Described now in detail is merchandise dispensing apparatus primarily designed for use in a retail store to dispense consumer items.  FIG. 1  is a perspective view of the apparatus, a box structure having a plurality of walls enclosing and defining an interior space. The walls prevent access to the interior space from at least a frontal, side, top and bottom approaches. The apparatus has a storage shelf  10  mounted in a wrap-around enclosure  20 . The enclosure  20  is preferably a sheet metal box with open front and rear, but closed on both of its sides and its top. Preferably, the shelf  10  closes the bottom of the enclosure  20 . The enclosure  20  may be mounted on wall standards as is shown in the Mason patent application U.S. 2007/0080123 which is hereby incorporated herein by reference, and this would prevent access to the interior space from the rear approach. Alternately the apparatus may be placed on a shelf or otherwise secured within a retail establishment in a manner that restricts access to the rear and which eliminates the possibility of being moved by unauthorized persons. This may be accomplished by being bolted in place. In use, the shelf  10  is locked within the enclosure  20  so that merchandises for sale (referred to herein as merchandise box  30 , are only accessible via a limiting dispensing process as will be described below.  FIG. 2  shows one merchandise box  30  that has been dispensed by turning the leftmost knob  40  which dispenses box  30  to a forward position on the shelf  10  lying against a front glass plate  50 . As shown in  FIG. 3 , a flat handle  60  is raised thereby lifting, from a closed attitude ( FIGS. 1 and 2 ), into an open attitude ( FIG. 3 ), a first movable wall, a top glass plate  70  mounted via a first hinge  71  ( FIG. 5 ), so that a person&#39;s hand, shown in phantom line, is able to reach into the apparatus from above to retrieve the dispensed box  30 . Notice that when the top glass plate  70  is raised, it simultaneously lowers a barrier strip  80 , which may have a message printed on it such as “Stop Theft At Retail.” Barrier strip  80 , engaged with plate  70  by a second hinge  74 , assumes a vertical position which blocks removal of any further of the merchandise boxes  30  other than the one dispensed as it bars access to any but the frontal portion F ( FIG. 3 ) of the interior space. Therefore, only one box  30  can be dispensed with each revolution of each of the knobs  40 . 
     To gain access to the self for loading merchandise boxes  30 , by operating personnel, key locks  22  are placed at left and at right lateral positions on the shelf  10  and when these locks are opened by keys, as shown in  FIG. 3 , the self  10  is able to be drawn out of the enclosure  20  on drawer glides  90  to a forward position, as shown in  FIG. 4 . In this view, the front glass plate  50  is removed in order to clearly show details. Three merchandise support modules  100  are shown mounted on shelf  10  in this view, and one or more further modules  100  may be mounted in the empty space shown on the left side of shelf  10 . 
     In  FIG. 5  we see shelf  10  drawn partly out of enclosure  20  with the front glass plate  50  mounted and held in place by thumbscrews  130 ; one on each side of shelf  10 . Clearly, plate  50  cannot be removed when shelf  10  is fully inserted within enclosure  20  since thumbscrews  130  are not accessible at that time. Therefore, plate  50  provides a primary merchandise theft deterrent means in the present invention. 
     In  FIG. 6  top glass plate  70  is shown in its raised position. Plate  70  pivots on hinges secured by fasteners  71  on opposing sides of enclosure  20 . On each side also, are vertical slots  140  within which ride screws  72  which control the attitude of barrier strip  80 . Referring to  FIG. 3  we see that barrier strip  80  is hinged via piano hinge  74  to top glass plate  70 , so that when plate  70  is raised, sign  80  is rotated into the vertical position shown in  FIGS. 3 and 6 , and screws  72  are at the bottom of slots  140 . Likewise, when plate  70  is lowered, as shown in  FIG. 5 , it also forces barrier strip  80  into a horizontal position where screws  72  are at the top of slots  140  ( FIG. 5 ), uncovering merchandise boxes  30  which are mounted on modules  100  and thereby providing access for shelf  10  to be pulled out of enclosure  20  for loading further merchandise boxes  30 . 
     In  FIGS. 7-11  we will now describe modules  100  which are all identical.  FIG. 7  shows a module  100  in its upright attitude as when mounted on shelf  10 . Forward module slots  102  at the knob end of module  100  engage forward shelf slots  12  as shown in  FIG. 4  thereby holding modules  100  in position on shelf  10 . In  FIG. 8  we see that module  100  provides rear module slots  104  which engage rear shelf slots  14  shown in  FIG. 4 . Therefore modules  100  are secured and immovable on shelf  10  from left to right and also front to back. In  FIGS. 7 and 8  we see that a top surface  106  of module  100  has a longitudinal slot  180  which runs over a majority of the length of the module  100 . Mounted in slot  180  is compression trolley  170  which is engaged with slot  180  via a wider portion  180 A at the rear end of module  100 , best shown in  FIG. 8 . Trolley  170  carries a clock spring  190  which is secured in spring slot  108 . When trolley  170  is pressed toward the rear of module  100  clock spring  190  unreels and is wound tighter as a portion  190 A of spring  190  reels out, as shown in  FIG. 7 . This provides the force for pressing merchandise boxes  30  toward the knob end of module  100 . As shown in  FIG. 8  one or more merchandise boxes  30  may be rested on top surface  106  and compressed between trolley  170  and a fixed stop plate  160  which is secured at a forward position on module  100  and protrudes above surface  106 , as shown in  FIG. 7 . A side wall  200  is shown at one side of the module  100  and carries a flange  202  which is essentially at the level of top surface  106  so that with merchandise boxes  30  sitting on surface  106  and abutting side wall  200 , boxes  30  also rest on flange  202 . In one embodiment, the boxes  30  rest on flanges  202  on each side of boxes  30  but are thereby raised slightly above surface  106  so as not to interfere with the extended portion  190 A of spring  190 . 
       FIG. 9  is a bottom perspective view of module  100  showing the side wall  200  with flange  202  in a corresponding opposing position on side wall  200  as the flange  202  in  FIG. 7 . Flange  202  in  FIG. 7  functions for controlling a merchandise box  30  on module  100 , while the flange  202  in  FIG. 9  controls a merchandise box  30  on an adjoining module as shown in  FIG. 4 . Side wall  200  provides three slots  220  which are formed on a bottom plate  200 A of side wall  200  and which is integral with it. Three studs  210  grip bottom plate  200 A while allowing it to move over a linear excursion limited by the length of slots  220  so that side wall  200  is able to be positioned laterally to accommodate merchandise boxes  30  of various widths. In setting up the modules  100  in shelf  10 , as shown in  FIG. 4 , first a module  100  is selected for each size merchandise box  30  that is to be displayed, and each side wall  200  is adjusted laterally so as to contact one side of its respective box  30  when box  30  is laterally centered on surface  106  of its respective module  100 . Working from left to right on shelf  10 , the adjusted modules  100  are placed on shelf  10  and engaged with slots  12  and  14  in their respective strips, with the side wall  200  of each next module positioned against the merchandise box  30  of the module  100  to its right. Since modules  100  can only be positioned on shelf  10  in certain discrete locations dictated by the locations of slots  12  and  14 , some experimentation in the order of placement of modules  100  may be required. In this manner, each line of merchandise boxes  30  will have a side wall  200  on both of its opposite vertical sides, forming a guide way G ( FIG. 4 ) so that when a box  30  is dispensed the remaining boxes  30  are guided as they are pressed forward by trolley  170 . 
       FIG. 9  also shows the location of a merchandise ejector  230  which is housed within each module  100  so that merchandise boxes  30  on each module  100  may be dispensed independently of any other of the modules  100 .  FIG. 10  is a close-up view of mechanism  230  which is used to dispense the first merchandise box  30 , i.e., the one that is in the most forward position on module  100  and so rests against stop plate  160  prior to being dispensed. Now referring to  FIG. 10 , when knob  40  is rotated, a shaft  240  which is joined to, and extends rearward from the knob  40 , causes a crank  250  to move in a slot  260  in a movable ejector plate  270 . The ejector plate  270  is therefore caused to slide linearly within ejector plate support  280  upwardly toward surface  106 . As shown in  FIG. 11 , ejector plate  270  then moves through slot  290  in surface  106  of module  100  and protrudes at its highest above fixed stop  160  so that the first merchandise box  30 , which is resting against fixed stop  160 , is pushed above it. When this happens, the spring tension that is delivered to the first merchandise box  30  by trolley  170  through any intervening boxes  30  that may be in line behind the first box  30 , delivers an ejecting force to the lifted first box  30  causing it to move forward in the apparatus coming to rest against front glass plate  50  as shown in  FIG. 2 , where it is ready to be manually removed through open top glass plate  70 . The rotation of knob  40  continues so that ejector plate  270  moves at once down through slot  290  into the position shown in  FIG. 10  thereby completing one ejection cycle. With the first box  30  and also ejector plate  270  no longer present, the next box  30  in line is forced to move up against fixed stop  160  and is therefore in position to be ejected whenever knob  40  is next rotated. Preferably, knob  40  is mounted on the front end  100 A of module  100  by knob stem  42  which is best seen in  FIG. 12 . In  FIG. 10  it is shown that knob stem  42  is joined with shaft  240 . On an interior circular sidewall  44  of knob  40  are mounted ribs  46  as shown in  FIG. 12 . Mounted on front end  100 A with screws  101  ( FIG. 10 ) is knob insert  48 . Insert  48 , as best seen in  FIG. 13 , provides flexible cantilevered fingers  48 A which extend into the interior of knob  40 . When knob  40  is rotated, fingers  48 A engage ribs  46  and are thereby bent and then released at least several times as knob  40  continues to rotate one revolution, and it is the release of spring energy stored in fingers  48 A that makes a noise. Therefore, when a merchandise box  30  is dispensed, this tell-tale noise is produced alerting others in the vicinity that a dispensing action is taking place. The noise mechanism may be any means for producing an audible noise other then the preferred embodiment described here. 
     The enablements described in detail above are considered novel over the prior art of record and are considered critical to the operation of at least one aspect of the apparatus and its method of use and to the achievement of the above described objectives. The words used in this specification to describe the instant embodiments are to be understood not only in the sense of their commonly defined meanings, but to include by special definition in this specification: structure, material or acts beyond the scope of the commonly defined meanings. Thus if an element can be understood in the context of this specification as including more than one meaning, then its use must be understood as being generic to all possible meanings supported by the specification and by the word or words describing the element. 
     The definitions of the words or drawing elements described herein are meant to include not only the combination of elements which are literally set forth, but all equivalent structure, material or acts for performing substantially the same function in substantially the same way to obtain substantially the same result. In this sense it is therefore contemplated that an equivalent substitution of two or more elements may be made for any one of the elements described and its various embodiments or that a single element may be substituted for two or more elements in a claim. 
     Changes from the claimed subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalents within the scope intended and its various embodiments. Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements. This disclosure is thus meant to be understood to include what is specifically illustrated and described above, what is conceptually equivalent, what can be obviously substituted, and also what incorporates the essential ideas. 
     The scope of this description is to be interpreted only in conjunction with the appended claims and it is made clear, here, that each named inventor believes that the claimed subject matter is what is intended to be patented.
