Description




FIELD OF THE INVENTION




The present invention relates generally to coin handling devices and, more particularly, to a coin handling device with a folding escalator.




BACKGROUND OF THE INVENTION




At the end of a gaming session on a coin-out gaming machine, a player presses a “cashout” or “collect” button and collects a number of coins corresponding to the number of credits remaining on the machine's credit meter. The gaming machine contains a coin handling device filled with coins. The coin handling device delivers the appropriate number of coins to a coin outlet and dispenses the coins into a coin tray or bin via the coin outlet. The coin handling device includes at least a coin hopper.




If, however, the coin tray is located above the hopper as in many slant-top gaming machines, the coin handling device may also include a coin escalator extending upwardly from the hopper to the coin outlet. The hopper may be mounted to the floor of the machine cabinet, while the coin tray is approximately adjacent to a button panel at a height well above the floor of the machine cabinet. The escalator successively receives coins from the hopper and conveys them upwardly in a single file to the coin outlet. It is sometimes necessary to remove the coin handling device from the cabinet for servicing or replacement. Because the escalator extends upwardly from the hopper, however, the cabinet may not provide sufficient clearance for removal and later installation of the coin handling device without tilting the device awkwardly as it is removed/installed or somehow disconnecting the escalator from the hopper prior to removal/installation. A need therefore exists for a coin handling device with escalator that facilitates removal of the device from the gaming machine cabinet and installation of the device into the cabinet.




SUMMARY OF THE INVENTION




A coin handling device comprises a hopper and an escalator for receiving coins from the hopper. The escalator is connected to the hopper and extends upwardly from the hopper. At least a portion of the escalator is downwardly foldable toward the hopper to reduce an overall height of the coin handling device. The reduced height facilitates removal of the coin handling device from a gaming machine cabinet and installation of the device into the cabinet in the event the cabinet provides minimal clearance.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS




Turning now to the drawings,

FIGS. 1

,


2


, and


3


depict a coin handling device


10


comprising a coin hopper


12


and a coin escalator


14


for receiving coins from the hopper


12


. The escalator


14


successively receives coins from the hopper


12


and conveys them upwardly in a single file to a coin outlet of a gaming machine that houses the coin handling device


10


. The coins are dispensed into a coin tray or bin via the coin outlet. The escalator


14


is connected to the hopper


12


and extends upwardly from the hopper


12


. A substantial upper portion


16


of the escalator


14


is downwardly foldable toward the hopper


12


to reduce an overall height of the coin handling device


10


. During normal use of the coin handling device


10


, the escalator portion


16


is disposed in a generally vertical position as shown in

FIG. 2

so that the coin handling device


10


has an overall height H


1


. When, however, the coin handling device


10


must be removed from a gaming machine cabinet for servicing or replacement or installed into the cabinet, the escalator portion


16


is folded downward from the generally vertical position to a generally horizontal position shown

FIG. 3

so that the overall height of the coin handling device


10


is reduced to H


2


.




Referring to

FIGS. 4 and 5

, the upper escalator portion


16


is connected to a remaining lower portion


18


of the escalator


14


by an inboard pivot


20


and an outboard latching mechanism


22


. The inboard pivot


20


preferably includes a pin and a bearing. The outboard latching mechanism


22


preferably includes a spring-loaded latch pin


22




a


and associated aperture


22




b


. The latch pin


22




a


is mounted to the lower escalator portion


18


, while the aperture


22




b


is formed in the upper escalator portion. During normal use of the coin handling device


10


, the spring-loaded latch pin


22




a


engages with the aperture


22




b


to hold the escalator portion


16


in the vertical position. When, however, the coin handling device


10


must be removed from the cabinet for servicing or replacement, the latch pin


22




a


is released from the aperture


22




b


to allow the escalator portion


16


to be folded or pivoted about the inboard pivot


20


from the vertical position to the horizontal position. The escalator portion


16


is folded in an imaginary plane occupied by the escalator


14


, the inboard pivot


20


, and the outboard latching mechanism


22


.




Referring to

FIGS. 7 and 8

, the coin handling device


10


preferably includes a retention mechanism


24


for retaining any coins in the escalator portion


16


while it is folded. The retention mechanism


24


preferably includes a spring-loaded arm


24




a


, a pin


24




b


, a torsion spring


24




c


, and a curved slot


24




d


. The pin


24




b


is mounted to an end of the arm


24




a


and is movable through the curved slot


24




d


formed in the escalator portion


16


. The arm


24




a


is biased in a clockwise direction by the torsion spring


24




c


. The retention mechanism


24


is always active—during normal use of the coin handling device


10


and while the escalator portion


16


is folded. As coins are conveyed upwardly through the escalator


14


and pass through the junction between the upper escalator portion


16


and the lower escalator portion


18


, each coin pushes against the pin


24




b


and thereby forces the arm


24




a


and attached pin


24




b


to move counterclockwise against the bias of the torsion spring


24




c


. Once the coin passes through the junction, the arm


24




a


and attached pin


24




b


return clockwise to the home position, where the pin


24




b


now stops the coin from falling downward back through the junction. In an alternative embodiment, the retention mechanism


24


may be designed to be activated by the release of the latching mechanism


22


and deactivated by the latching of the latching mechanism


22


, such that it is only active while the escalator portion


16


is folded.




As shown in

FIGS. 2 and 3

, another coin retention mechanism


30


is preferably disposed at the exit end of the escalator portion


16


. The retention mechanism


30


includes a spring-loaded arm biased toward the illustrated position. The spring-loaded arm controls coins as they exit from the escalator portion


16


and, at the same time, prevents any coins in the escalator portion


16


from falling out via its exit end. As a coin exits from the escalator portion


16


, the coin pushes past the spring-loaded arm which, in turn, triggers a coin counter


28


.




Referring to

FIGS. 5 and 6

, the coin handling device


10


includes a continuity mechanism


26


for sensing whether or not the escalator portion


16


is folded. The continuity mechanism


26


may be an electrical, magnetic, proximity, or other type of sensor known in the art. In the illustrated embodiment, the continuity mechanism


26


is an electrical sensor formed by a conductive spring


26




a


and a pair of insulated electrical wires


26




b


and


26




c


. The conductive spring


26




a


is mounted to the upper escalator portion


16


. The wires


26




b


and


26




c


terminate in respective conductive contacts mounted within an insulating plate


26




d


. The insulating plate


26




d


is mounted to the lower escalator portion


18


. When the escalator portion


16


is not folded (i.e., vertical) toward the hopper


12


as in

FIG. 2

, the conductive spring


26




a


creates an electrical path between the wires


26




b


and


26




c


. When the escalator portion


16


is folded (i.e., horizontal) toward the hopper


12


as in

FIG. 3

, the electrical path between the wires


26




b


and


26




c


is broken because the conductive spring


26




b


no longer bridges the conductive contacts at the upper ends of the wires


26




b


and


26




c.






The continuity mechanism


26


may be used to selectively disable the coin counter


28


(see

FIG. 2

) coupled to the mechanism. When the continuity mechanism


26


indicates that the escalator portion


16


is not folded toward the hopper


12


as in

FIG. 2

, the coin counter


28


counts any detected coins exiting from the coin escalator


14


. However, when the continuity mechanism


26


indicates that the escalator portion


16


is folded toward the hopper


12


as in

FIG. 3

, the coin counter


28


is preferably disabled so that the counter does not inadvertently detect and count any coins that may shift in the escalator


14


during the folding process. By disabling the coin counter


28


during the folding process, the counter will not receive any superfluous signals from its coin sensor. In addition to disabling the coin counter


28


, the hopper


12


is preferably disabled while the escalator portion


16


is folded toward the hopper


12


.
