Abstract

An improved coin receiving mechanism having a foreign object release device. The invention includes first and second chute walls having spaced apart inner surfaces which are substantially parallel to each other when the mechanism is in an unactivated state. The inner surfaces define the walls of a coin chute path through which a coin travels. The first and second chute walls each further have an upper chute wall portion, disposed adjacent an entrance to the coin chute path, and a lower chute wall portion, disposed adjacent to and in communicating relationship with an exit of the coin chute path. The first and second coin chute walls are hingedly mounted to a frame. The invention also includes provisions for moving the coin chute walls from the unactivated state to an activated state wherein the coin chute walls are first pivoted together until the lower chute portions of each of the first and second chute walls are no longer disposed in communicating relationship with the exit of the coin chute path. The coin chute walls are then pivoted separately with the coin chute wall which is further from the exit being pivoted to a greater extent so that the coin chute walls open to eject foreign objects caught between the coin chute walls and thereby clear the coin chute path while restricting the objects from falling into the exit.

Claims

1. A coin receiving mechanism having a foreign object release device for use with a coin receiving machine, said mechanism comprising:

(a) first and second chute walls having spaced apart inner surfaces which are substantially parallel to each other when said mechanism is in an unactivated state and wherein said inner surfaces define left and right walls of a coin chute path through which a coin travels, said first and second chute walls each further having an upper chute wall portion and a lower chute wall portion, wherein said upper chute wall portion is disposed adjacent an entrance to said coin chute path and wherein said lower chute wall portion is disposed adjacent to and in communicating relationship with an exit of the coin chute path;

(b) a frame onto which said left and right chute walls are hingedly mounted;

(c) an actuating lever having a first end pivotally mounted to said frame and a second end disposed opposite thereto;

(d) a roller rotatably mounted on a roller bracket which is fixedly attached to said first coin chute wall, wherein said roller is disposed upon an upper actuating lever surface of said actuating lever, wherein when said actuating lever is not activated, said coin chute walls remain in said unactivated state, and wherein when said actuating lever is caused to pivot in a clockwise direction, with the second end of the actuating lever moving upward, said roller is caused to ride up on the upper actuating lever surface toward said second end of said actuating lever, and in turn said first coin chute wall is caused to pivot in said clockwise direction to an activated state; and

(e) a first spring member disposed between said second chute wall and said frame, said first spring member causing said second chute wall to pivot in said clockwise direction with said first chute wall until, but not substantially further than, a position in which said lower chute portions of the first and second chute are no longer in communicating relationship with said exit of said coin chute path, and wherein said first coin chute wall may continue to move in said clockwise direction beyond said position in which said lower chute portions are no longer in communicating relationship with said exit so that the coin chute walls open to eject foreign objects caught between said coin chute walls and thereby clear said coin chute path while restricting said objects from falling into said exit.

2. The coin receiving mechanism of claim 1, further comprising a second spring member disposed between said frame and said first coin chute wall, said second spring member causing said first and second chute walls, said roller, said roller bracket and said actuating lever to return to their respective unactivated positions when said actuating lever is released by a user of the coin receiving mechanism.

3. The coin receiving mechanism of claim 2, further comprising a rocker actuator fixedly mounted to said second coin chute wall, a rocker rotatably mounted about a shaft on said frame, said rocker having an upper end and pivotally engaged with said rocker actuator and a lower end which is adjacent to an exit ramp fixedly attached to an eject door of said coin accepter/counter device, and wherein said lower end of said rocker is not in contact with said exit ramp until said second coin chute is pivoted in a clockwise direction until said first and second chute walls are no longer in communicating relationship with said exit.

4. The coin receiving mechanism of claim 3 wherein said eject door is mounted to the coin accepter/counter device'"'"'s main body by a spring hinge and wherein said spring hinge urges said door toward a closed position.

5. The coin receiving mechanism of claim 4 wherein said roller bracket is also fixedly attached to a shutter and wherein said shutter has a shutter bracket which engages said rocker actuator after said coin chute walls have opened, whereby as said actuating lever is continued to be moved in said clockwise direction, the second chute wall is caused to move further in the clockwise direction, the rocker actuator causes the rocker to rotate further in the counterclockwise direction, the lower end of said rocker to push against said exit ramp and to open said eject door.
