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 . fig1 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 . fig2 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 fig3 , a flat handle 60 is raised thereby lifting , from a closed attitude ( fig1 and 2 ), into an open attitude ( fig3 ), a first movable wall , a top glass plate 70 mounted via a first hinge 71 ( fig5 ), 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 ( fig3 ) 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 fig3 , the self 10 is able to be drawn out of the enclosure 20 on drawer glides 90 to a forward position , as shown in fig4 . 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 fig5 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 fig6 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 fig3 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 fig3 and 6 , and screws 72 are at the bottom of slots 140 . likewise , when plate 70 is lowered , as shown in fig5 , it also forces barrier strip 80 into a horizontal position where screws 72 are at the top of slots 140 ( fig5 ), 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 fig7 - 11 we will now describe modules 100 which are all identical . fig7 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 fig4 thereby holding modules 100 in position on shelf 10 . in fig8 we see that module 100 provides rear module slots 104 which engage rear shelf slots 14 shown in fig4 . therefore modules 100 are secured and immovable on shelf 10 from left to right and also front to back . in fig7 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 fig8 . 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 fig7 . this provides the force for pressing merchandise boxes 30 toward the knob end of module 100 . as shown in fig8 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 fig7 . 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 . fig9 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 fig7 . flange 202 in fig7 functions for controlling a merchandise box 30 on module 100 , while the flange 202 in fig9 controls a merchandise box 30 on an adjoining module as shown in fig4 . 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 fig4 , 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 ( fig4 ) so that when a box 30 is dispensed the remaining boxes 30 are guided as they are pressed forward by trolley 170 . fig9 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 . fig1 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 fig1 , 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 fig1 , 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 fig2 , 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 fig1 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 fig1 . in fig1 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 fig1 . mounted on front end 100 a with screws 101 ( fig1 ) is knob insert 48 . insert 48 , as best seen in fig1 , 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 .
a box structure has a plurality of walls positioned and configured to prevent access to an interior space housing merchandise in a secure manner . a first movable wall permits manual access to a frontal portion of the interior space while at the same time moving a barrier strip to prevent manual access to other than said frontal portion of the interior space . a roll - out shelf mounts merchandise supporting modules with pushers to move merchandise toward the front of the structure where ejection mechanisms in each of the modules are able to direct selected items to the front of the structure where they can be accessed by consumers . the ejection process creates a characteristic noise to alert store personnel that products are being dispensed .
