Abstract

An apparatus for collecting refuse, the apparatus comprising a vehicle having a frame formed as two substantially parallel members and a hopper secured to the frame. First and second bins may be connected by respective first and second dumping mechanisms to opposite, exterior sides of the hopper. The first and second dumping mechanisms may selectively and independently move respective first and second bins between stowed positions substantially below the hopper and dumping positions above the hopper. The width between the exterior extremes of the first and second bins when both are in stowed positions may substantially be defined by a summation of the width of the first bin, the distance between the outer extremes of the frame, and the width of the second bin.

Claims

1. An apparatus comprising:

a vehicle comprising a frame formed as two substantially parallel members extending lengthwise and a hopper secured to the frame;

first and second bins sized to receive refuse therein;

first and second dumping mechanisms connecting respective first and second bins to opposite, exterior sides of the hopper and selectively and independently moving respective first and second bins between stowed positions substantially below the hopper and dumping positions above the hopper; and

the vehicle, wherein the maximum width of the vehicle and first and second bins, when the first and second bins are both in the stowed position, is within the legal limit of vehicle width.

2. The apparatus of claim 1, wherein the maximum width of the vehicle and first and second bins, when the first and second bins are both in the stowed position, is less than or equal to about one hundred two inches.

3. The apparatus of claim 2, wherein the first bin comprises a first engagement mechanism positioned on an exterior thereof to engage and secure a standardized refuse container, freestanding and associated with a third party.

4. The apparatus of claim 3, wherein the second bin comprises a second engagement mechanism positioned to extend beyond an exterior surface thereof to engage and secure a standardized refuse container.

5. The apparatus of claim 4, wherein the first bin has at least one roller positioned at each of a forward end and a rearward end thereof.

6. The apparatus of claim 5, wherein the first dumping mechanism comprises:

a first track secured to the hopper to guide the at least one roller positioned at the forward end of the first bin; and

a second track secured to the hopper to guide the at least one roller positioned at the rearward end of the first bin.

7. The apparatus of claim 6, wherein the first dumping mechanism further comprises:

a torsion tube;

a first linkage connecting the forward end of the first bin to the torsion tube; and

a second linkage connecting the rearward end of the first bin to the torsion tube.

8. The apparatus of claim 7, wherein the first dumping mechanism further comprises a third linkage connecting the torsion tube to the hopper, the third linkage selectively controlling rotation of the torsion tube with respect to the hopper.

9. The apparatus of claim 8, wherein the vehicle further comprises a body secured to the frame, the body having a first opening operably communicating from the hopper to the body, and at least one rail extending from the hopper, through the first opening, to the body.

10. The apparatus of claim 9, further comprising an ejector comprising a first platen positioned within the body, a sled secured to the first platen and slidingly engaging the rail, and a first hydraulic cylinder connecting the sled to the vehicle to selectively advance and retract the sled with respect thereto.

11. The apparatus of claim 10, further comprising a packer comprising a second platen slidingly engaging the rail and a second hydraulic cylinder connecting the second platen to the sled to advance and retract the second platen with respect thereto.

12. The apparatus of claim 11, wherein the packer is positioned to advance and retract substantially exclusively within the hopper when the ejector is in a retracted position.

13. The apparatus of claim 12, wherein the first platen has a second opening corresponding to the first opening.

14. The apparatus of claim 13, wherein the second platen has a perimeter corresponding to a perimeter of the hopper.

15. The apparatus of claim 14, wherein the first platen has a perimeter corresponding to a perimeter of the body.

16. The apparatus of claim 15, further comprising a third hydraulic cylinder connecting the sled to the vehicle, the third hydraulic cylinder working in conjunction with the first hydraulic cylinder to advance and retract the sled with respect thereto.

17. The apparatus of claim 16, wherein the third linkage comprises a fourth hydraulic cylinder.

18. The apparatus of claim 17, wherein the first dumping mechanism comprises a single hydraulic cylinder only.

19. The apparatus of claim 18, wherein the first, second, third, and fourth hydraulic cylinders are each single-stage, double-acting hydraulic cylinders.

20. The apparatus of claim 1, wherein the vehicle further comprises a body provided with an opening connecting the hopper to the body, and at least one rail extending from the hopper, through the opening, to the body.
