Sanitized vending machine having cup shielding mechanism
A sanitized vending machine includes product and cup dispensing mechanisms and an actuation mechanism. The product dispensing mechanism, holding product items, rotates through a product dispensing cycle to dispense them. The cup dispensing mechanism, holding a stack of cups, rotates through a cup dispensing cycle to dispense an empty cup to an intermediate location in a drop chute spaced above a final discharge location. Dispensing cycles occur in a predetermined sequence enabling the dispensed product items to be received in a previously dispensed empty cup. A cup shielding mechanism is actuated, in response to an access door being pivoted from a closed to open position, to translate from a retracted to extended position wherein any person reaching past the open access door into the machine is obstructed from being able to reach the empty cup at the intermediate location where the cup will receive product items during the next actuation cycle.

BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention generally relates to vending machines and, more particularly, is concerned with a sanitized vending machine having a cup shielding mechanism disposed below a drop chute that will actuate, in response to an access door on the machine being pivoted from a closed position to an opened position at the end of a given actuation cycle, to obstruct any person reaching past the access door into the machine from being able to reach a cup disposed at the intermediate location in the drop chute that will receive product items during a next actuation cycle.
2. Description of the Prior Art
Most prior art bulk coin-operated vending machines dispense their product items, such as candy or gum, into a non-removable cup fixed on, and ordinarily openable by manipulation of a pivotal flap mounted on the outside of, the housing of the machine which can be contacted and thus potentially contaminated by users' hands. The inventor of the subject matter disclosed herein has discerned that it is likely there are many potential users who would prefer alternative approaches for product items to be dispensed from bulk vending machines so that the dispensed product items cannot be contaminated through contact with parts of the vending machines which can be contacted and contaminated by users. An innovation which attempted to provide one alternative approach is disclosed in U.S. Pat. No. 7,066,351 by the inventor of the subject matter disclosed herein.
However, it is perceived by the inventor of the subject matter disclosed herein that a need still exists for other alternative approaches to sanitized dispensing from bulk coin-operated vending machines that incorporate appropriate mechanisms that assist in the fulfillment of such need.
SUMMARY OF THE INVENTIONThe present invention relates to a sanitized vending machine that incorporates coordinating mechanisms that work to prevent all users from contaminating product items and parts of the machine that contact the product items, by only allowing the occurrence of certain actions within the machine and behind an external access door on the machine, and thus inaccessible to all users. These coordinating mechanisms generally result in, first, dispensing a cup from a stack thereof by dropping it via a drop chute to an intermediate location in the drop chute, second, dispensing one or more selected product items from a supply thereof by dropping them via the drop chute into the dispensed cup while retained at the intermediate location, and, third, concurrently releasing and dropping the dispensed cup containing the product items from the drop chute to a discharge location behind the access door and allowing a user to open the access door in order to remove the dispensed cup containing the product items from the discharge location. The dispensed cup with the product items therein can only be removed from the discharge location in the machine upon the access door being enabled to be opened due to a given user operating the machine to make a purchase through depositing the required coins into the machine and turning an external handle on the machine through a given actuation cycle. An appropriate one of these coordinating mechanisms must have the capability of being able to reliably obstruct any person reaching past the opened access door into the machine from being able to reach the empty cup disposed at the intermediate position above the discharge location.
The present invention provides an appropriate mechanism in the sanitized vending machine in the form of a cup shielding mechanism associated with the drop chute and coordinated with operation of the access door. The cup shielding mechanism, being disposed adjacent to the drop chute and the discharge location, will actuate, in response to the access door on the machine being pivoted from a closed position to an opened position at the end of a given actuation cycle, to obstruct any person reaching into the machine past the opened access door from being able to reach the empty cup disposed at the intermediate location in the drop chute above the discharge position that will receive product items during the next actuation cycle.
Accordingly, the present invention provides a sanitized vending machine which includes: a product dispensing mechanism adapted to hold a plurality of product items and rotate through a product dispensing cycle during which the product dispensing mechanism dispenses one or more of product items; a cup dispensing mechanism adapted to hold at least one stack of cups and rotate through a cup dispensing cycle during which the cup dispensing mechanism dispenses a cup from the stack; a drop chute disposed below and in communication with the product and cup dispensing mechanisms and being adapted to receive and guide dispensed product items and a dispensed cup to an intermediate location in the drop chute, being spaced below the product and cup dispensing mechanisms and above a discharge location, where the dispensed cup is temporarily retained awaiting receipt of dispensed product items therein, the drop chute being further adapted to release the dispensed cup in response to receipt of the dispensed product items therein and guide the same to the discharge location below the drop chute; an actuation mechanism including a rotatable actuator being adapted upon actuation to cause rotation of the product and cup dispensing mechanisms, and a handle coupled to the rotatable actuator and adapted to be turned by a user to actuate the rotatable actuator by rotating the rotatable actuator through an actuation cycle that causes rotation of the product and cup dispensing mechanisms through the respective product and cup dispensing cycles in a predetermined sequence so that dispensed product items during a next actuation cycle are received in the dispensed cup being located at the intermediate location thereby ensuring that only a cup with product items therein is dropped to the discharge location during each actuation cycle; an access door being movable between a closed position and an opened position to allow a user to remove a dispensed cup containing product items from the discharge location when the access door in the opened position; and a cup shielding mechanism disposed adjacent to the drop chute and the discharge location and being actuated, in response to the access door being pivoted from the closed position to the opened position, to translate from a retracted position to an extended position wherein the extended position any person reaching past the opened access door into the housing is obstructed from being able to reach the dispensed cup disposed at the intermediate location in the drop chute above the discharge location where the cup will receive product items during the next actuation cycle.
More particularly, the cup shielding mechanism includes a bed disposed adjacent to, below and rearwardly of the drop chute and adjacent to, above and rearwardly of the discharge location such that the bed extends horizontally in a rearward direction away from the access door, and a plank slideably mounted in a track formed on a top side of the bed so as to be translatable relative to the bed between the retracted and extended positions. The cup shielding mechanism further includes an arm fixed to and extending rearwardly from a back side of the access door such that the arm pivotally moves with the access door, and a resiliently yieldable arrangement stationarily anchored above the access door and extending between and interconnecting an end of the arm, a rear end of the plank and a rear end of the bed so as to cause the plank to slide relative to the bed to the extended position in response to the access door being pivoted open, wherein the plank underlies the bottom of an empty cup at the intermediate location in the drop chute, and to the retracted position in response to the access door being pivoted closed, wherein the plank is withdrawn from under the empty cup at the intermediate location in the drop chute.
These and other features and advantages of the present invention will become apparent to those skilled in the art upon a reading of the following detailed description when taken in conjunction with the drawings wherein there is shown and described an illustrative embodiment of the invention.
In the following detailed description, reference will be made to the attached drawings in which:
Referring to the drawings, and particularly to
Referring to
The product dispensing mechanism 26 includes a product dispensing device 38 disposed through a front portion 34A of the opening 34 and within a front cavity 36 of the well structure 32 above a front bottom wall 32A thereof. The product dispensing device 38 is rotatably supported by a central tubular portion 38A thereof which fits over a pedestal 32C attached on and extending upwardly from the front bottom wall 32A. The product dispensing device 38 underlies the chamber 30 of the storage magazine 24 to receive the predetermined number of product items from the storage magazine 24 into each compartment 38B of the product dispensing device 38 radially extending outwardly from and circumferentially displaced about the central tubular portion 38A thereof. Upon rotation of the product dispensing device 38 through 120° of a 360° circular path of travel during each product dispensing cycle, the product items received in a given one of the compartments 38B are successively carried by the product dispensing device 38 under a stationary cover portion 26A of the product dispensing mechanism 26 and across an opening 40 in the front bottom wall 32A of the well structure 32 at which the product items then fall (in other words, are dispensed) through the opening 40.
The product dispensing device 38 also includes a first driven gear 42 defined about its lower periphery portion 38C. The well structure 32 has an opening 32E at a front end of the front cavity 36 facing the rear of the coin-operated actuation mechanism 28 of the product vending apparatus 20. Front portions of the product dispensing device 38 and the first driven gear 42 project through the front end opening 32E of the well structure 32 so that the first driven gear 42 can maintain an operative interfaced or driven relationship with the coin-operated actuation mechanism 28 as will be described hereinafter.
Referring to
During a given actuation cycle, at least one coin is deposited by a user through a coin slot 60 along the top of the mounting plate 44. The coin is received by the coin carrier 50 which holds the coin as the handle 48 is turned by the user and the shaft 46, coin carrier 50 and drive gear 52 therewith are rotated through a 360° path of travel during the given actuation cycle. The rotation of the coin carrier 50 transfers the coin to and releases it at a coin storage location (not shown) in the housing base 16. The rotation of the drive gear 52, which underlies and drivingly meshes, interfaces or engages directly with the first driven gear 42 on the rotatable dispensing device 38, causes rotation of the first driven gear 42 and thus the product dispensing device 38 therewith. The ratio of the sizes of the respective gears 42, 52 is such that the first driven gear 42 and thus the product dispensing device 38 rotate through 120° each dispensing cycle in response to rotation of the shaft 46 and drive gear 52 by the turning of the handle 48 through the entire 360° circular path of travel during the given actuation cycle. Thus, the dispensing of one or more product items occurs from a successive one of the compartments 38B of the product dispensing device 38 through the product dispensing opening 40 in the front bottom wall 34A of the well structure 34 during each actuation cycle of the coin-operated actuation mechanism 28 of the product vending apparatus 20 of the vending unit 14.
Referring to FIGS. 3 and 5-8, the cup dispenser apparatus 22 of the vending unit 14 includes a cup dispensing mechanism 62 and outer and inner cup separator devices 64, 88. The vending unit 14 also includes a drop chute 66 disposed below and in communication with the product and cup dispensing mechanisms 26, 62. The cup dispensing mechanism 62 includes a cup magazine or holder device 68 disposed within a rear cavity 70 of the well structure 32 and being rotatably supported on a central pedestal 32D affixed upright on a rear bottom wall 32B of the well structure 32 (which rear bottom wall 32B is at a level lower than the level of the front bottom wall 32A). The cup holder device 68 includes a lower holder part 74 that is rotatably fitted over and supported by the central pedestal 32D and also by an interior ledge 32F of the well structure 32 such that the lower holder part 74 is disposed in a spaced relationship above the rear bottom wall 32B of the well structure 32. The cup holder device 68 also includes an upper holder part 76 (
The cup holder device 68 also includes multiple lower tubular columns 78 in the lower holder part 74 and multiple upper tubular columns 80 in the upper holder part 76 (
The cup dispensing mechanism 62 also includes a second driven gear 92 defined about the lower periphery of the lower holder part 74 of the cup holder device 68 on the top side of a peripheral flange 74A on the lower holder part 74 that overlies an interior ledge 32F in the rear cavity 70 of the well structure 32. The well structure 32 has an opening 93 at the intersection between its front and rear cavities 36, 70 such that as the product dispensing device first driven gear 42 rotates through the 360° circular path of travel, a rear portion thereof and a front portion of the cup dispensing mechanism gear 92 project through the opening 93 between the cavities 36, 70 of the well structure 32 and directly drivingly intermesh, engage or interface with one another. Such intermeshing will cause rotation of the cup holder device 68 through 120° of the 360° circular path of travel, and thus operation of the cup dispenser apparatus 22 through a cup dispensing cycle, upon rotation of the shaft 46 and drive gear 52 thereon by the turning of the handle 48 of the coin-operated actuation mechanism 28 through the 360° circular path of travel of a given actuation cycle to thereby cause the dispensing of the predetermined number of product items from one of the compartments 38B of the dispensing device 38 through the product dispensing opening 40 in the front bottom wall 32A of the well structure 32 and dispensing of a cup from one of the lower tubular columns 78 of the lower holder part 74 of the cup holder device 68 through the cup dispensing opening 86 in the rear bottom wall 32B of the well structure 32 in a manner that a cup C with product P therein will be delivered to an accessible location of the vending unit 14, as will be described hereinafter.
Referring to
The outer cup separator device 64 and the top of the inner cup separator device 88 are disposed in a spaced relationship above the rear bottom wall 32B of the well structure 32 at a height slightly greater than the height of one cup C and in a stationary relationship to the rotatable cup holder device 68. The top level of the outer cup separator device 64 lies in a horizontal plane just below the bottom level of the upper holder part 76 and aligned with the upper level of the lower holder part 74. The outer cup separator device 64 at its inner edge portion 64A extends tangentially to and slightly inwardly across through the outer slots 78A as their respective lower tubular columns 78 rotate past the outer cup separator device 64. The portion of the outer cup separator device 64 that overlies the cup dispensing opening 86 has an arcuate-shaped cam segment 94 defined therealong with a wedge-shaped or tapered entry end 94A that will ensure separation of the lowermost cup C from the next cup C above it in the stack S. To prevent the remaining stack of cups above the lowermost cup LC from also falling downward through the cup dispensing opening 86, the top of the inner cup separator device 88 has a radially outward protruding circular rim portion 88A extending through about 180° opposite from and co-extensive with the inner edge portion 64A of the outer cup separator device 64, The top rim R of the next higher cup C above the lowermost cup C of the two stacks approaching and leaving the location of the cup dispensing opening 86 overlies the inner edge portion 64A of the outer cup separator device 64 and the opposing rim portion 88A of the inner cup separator device 88 so as to support the remaining stack of cups thereon. The rim portion 88A of the inner cup separator device 88 is cut away for about the remaining 180° thereabout so as to withdraw support from the remaining stack of cups during travel through that portion of its circular path opposite from the location of the outer cup separator device 64, allowing the new lowermost cup and remaining stack to drop down onto the rear bottom wall 32B of the well structure 32 such that the top rim R of the new lowermost cup will be just below and thus pass under the inner edge portion 64A of the outer cup separator device 64 as well as below the protruding rim portion 88A of the inner cup separator device 88 in preparation for engaging with the wedge-shaped or tapered entry end 94A of the depending cam segment 94 of the outer cup separator device 64.
The dispensed empty cup drops downward through the funnel-shaped upper portion 66A of the drop chute 66 and into a substantially vertical lower portion 66B thereof until the top rim R of the released cup C encounters and is caught by a plurality of circumferentially-spaced apart pivotal protrusions or ledges 96 inwardly biased by springs 98 and mounted on pins 100 in recesses 102 at an intermediate location near where the upper portion 66A of the drop chute 66 merges into the lower portion 66B thereof. The cup C is stopped by the inwardly extended pivotal ledges 96, due to the bias of the springs 98, and temporarily held seated on the ledges 96 at the intermediate position about midway down the cup pathway until the product items guided by the drop chute 66 have dropped into the cup. The bias of the springs 98 is preselected such that the weight of the product and the cup is sufficient to overcome the bias of the springs 98 and cause the pivotal ledges 96 to pivot outwardly away from the cup C and allow the cup C with product items therein to drop to the final location on the base 16 of the housing 12 behind an exterior access door 104 pivotally mounted on the front of the vending machine 10 where cup C (

The access door locking mechanism 106 also includes an arm-shaped lock actuation device 114 mounted in the base 16 of the housing 12 above and aligned with the rod 108 so as to undergo vertical reciprocal movement during a given actuation cycle in a channel 117 defined by a stationary bracket 115 fixed on the housing 12. An upper arm portion 114A of the lock actuation device 114 underlies the peripheral edge portion 56A of the rotatable actuator wheel 56 of the coin-operated actuation mechanism 18 such that the peripheral edge portion 56A engages the upper arm portion 114A and depresses the lock actuation device 114 and then the rod 108 downward against the bias of the spring 112 such that the lower end 108B is inserted into a hole 116 in the base 16 of the housing 12 below the access door 104, locking the door against being pivoted away from the housing 12. When the handle 48 of the mechanism 28 has been turned to the end of a complete 360° circular path of travel of a given actuation cycle, the upper arm portion 114A of the lock actuation device 114 becomes aligned with the notch 56B in the peripheral edge portion 56A of the wheel 56, allowing the upper arm portion 114A of the lock actuation device 114 and the rod 108 to move upward due to the bias force of the spring 112 and retract the lower end 108B from the hole 116 in the base 16 of the housing 12. The access door 104 can then be opened and the cup with product therein removed. This arrangement will ensure that the cup cannot be removed prematurely.
The flow of driving torque begins when, after a user deposits the appropriate number of coins into coin slot 60, the user turns the handle 48 of the mechanism 28 clockwise, as viewed in
