Passive device for staging and dispensing objects

1. A passive dispensing chute assembly, comprising:

a chute configured to receive objects to be dispensed, the chute having an outlet;

a plurality of staging members, each of the staging members being suspended from and pivotally interconnected with the chute, the staging members being coupled to move together between a staging position, in which lower ends of the staging members are drawn together to form an impassable cone, and a dispensing position, in which the lower ends of the staging members radially withdraw from each other to permit passage of objects therethrough; and a plurality of contact members, each of the contact members having an upper end that is suspended from and pivotally interconnected with a respective lower end of a staging member, wherein in the staging position, the upper ends of the contact members define a circle having a first circumference, and in the dispensing position, the upper ends of the contact members define a circle having a second circumference that is greater than the first circumference;

wherein contact from underneath forces the contact members to move from the staging position toward the dispensing position.

2. The dispensing chute defined in claim 1 , wherein the staging members are biased toward the staging position.

3. The dispensing chute defined in claim 2 , wherein the staging members are biased via a spring-loaded mechanism.

4. The dispensing chute defined in claim 2 , wherein the staging members are biased toward the staging position by gravity.

5. The dispensing chute defined in claim 1 , wherein each of the staging members includes a panel and an overleaf, wherein, when the panels are in the staging position, the panels of the staging members form the impassable cone and each of the overleaves underlies an adjacent panel, such that movement of a panel toward the dispensing position also forces the overleaf of an adjacent panel toward the dispensing position.

6. The dispensing chute defined in claim 5 , wherein the panels are generally triangular in shape.

7. The dispensing chute defined in claim 5 , wherein each of the overleaves has generally a rounded triangular shape.

8. The dispensing chute defined in claim 1 , wherein the plurality of staging members comprises six staging members.

9. The dispensing chute defined in claim 1 , wherein the chute comprises upper and lower ends, and wherein the lower end is movable relative to the upper end, such that movement of the staging members toward the dispensing position causes the lower end of the chute to move toward the upper end of the chute.

10. A passive chute assembly, comprising:

a chute configured to receive objects to be dispensed, the chute having an outlet;

a passive dispensing unit attached to the chute outlet, the passive dispensing unit having a staging portion, wherein objects are captured prior to dispensing, the staging portion being movable between a staging position, in which objects may be captured within the staging portion, and a dispensing position, in which the objects may be fed gravimetrically into a receptacle positioned below the dispensing unit;

the staging portion including an adaptive opening that, when the staging portion moves to the dispensing position, opens adaptively corresponding to a diameter of the receptacle.

11. The passive chute assembly defined in claim 10 , wherein the adaptive opening is formed in a flexible spout.

12. The passive chute assembly defined in claim 10 , wherein the staging portion comprises a plurality of staging members, each of the staging members being suspended from and pivotally interconnected with the chute, the staging members being coupled to move together between the staging position, in which lower ends of the staging members are drawn together to form an impassable cone, and the dispensing position, in which the lower ends of the staging members radially withdraw from each other to permit passage of objects therethrough, the adaptive opening being formed by the lower ends of the staging members.
