Refuse collection system

1. An intermediate refuse collection container in combination with a convertible lifter assembly,

the convertible lifter assembly being configured for attachment to spaced lift members of a top loading refuse collection vehicle, the convertible lifter assembly allowing the vehicle to dump an intermediate collection container having fork-receiving apertures or pockets and to dump an intermediate collection container lacking fork receiving pockets, the convertible lifter assembly comprising:

a) cross member for extending between and attachment to the lift members of a top loading collection vehicle;

b) spaced-apart mounting connectors fixedly attached to the cross member and configured for selective non-destructive removable attachment to container lift forks for lifting intermediate containers having fork-receiving apertures or pockets or to an intermediate container having mating mounting members and being free of fork-receiving apertures or pockets; and

the intermediate refuse collection container for receiving refuse from a primary refuse container and being configured without fork receiving apertures or pockets to be carried by the convertible lifter assembly, the intermediate container comprising:

a) a front wall, a rear wall, opposed sidewalls, and a bottom wall defining a total refuse collection volume;

b) an extension assembly substantially beneath the total refuse collection volume intermediate the front wall and the rear wall, the extension assembly being movable between a first, retracted position for storage and for dumping a primary refuse collection container and a second, extended position for engaging and releasing the primary refuse collection container at a location laterally spaced from the intermediate container, the extension assembly further comprising a track assembly with first and second side frames horizontally spaced-apart along the bottom wall of the intermediate refuse collection container, a rigid extension member with first and second spaced-apart slide members, a slide member being associated with each side frame, and an actuator positioned between the slide members for moving the rigid extension member relative to the track assembly; and

c) a mounting base secured to the extension assembly and a primary refuse collection container lifter carried on the mounting base at a location lateral to a side wall of the intermediate container.

2. The combination of claim 1 in which each slide member of the rigid extension member has an outwardly-facing roller channel, and each of the spaced-apart side frames of the track assembly includes a plurality of rollers received within a respective one of the roller channels.

3. The combination of claim 1 in which the intermediate container includes spaced apart mounting members for mounting to the convertible lifter assembly.

4. The combination of claim 3 in which the intermediate container mounting members extend generally rearwardly from the intermediate container.

5. The combination of claim 3 in which the intermediate container mounting members are configured to engage the mounting connectors on the convertible lifter assembly so as to bring the mounting members and mounting connectors into alignment as the convertible lifter assembly and the intermediate container are moved into proximity during joinder.

6. The combination of claim 3 in which the intermediate container further comprises a brace extending rearwardly intermediate the container mounting members for attachment to the convertible lifter assembly.

7. An intermediate container for receiving refuse from a primary refuse container, and configured to be carried by a top-loading refuse collection vehicle having a top-loading refuse collection vehicle lifter, the intermediate container comprising:

a) a front wall, a rear wall, opposed sidewalls, and a bottom wall defining a total refuse collection volume;

b) an extension assembly substantially beneath the total refuse collection volume intermediate the front wall and the rear wall, a portion of the extension assembly being movable between a first, retracted position for storage and for dumping a primary refuse collection container and a second, extended position for engaging and releasing the primary refuse collection container at a location laterally spaced from the intermediate container and the refuse collection vehicle, the extension assembly further comprising a track assembly with first and second side frames horizontally spaced-apart along the bottom wall of the intermediate refuse collection container, a rigid extension member with first and second spaced-apart slide members, a slide member being associated with each side frame, and an actuator positioned between the slide members for moving the rigid extension member relative to the track assembly;

c) a mounting base secured to the extension assembly and configured for mounting a primary refuse collection container lifter thereon; and

d) the intermediate container being free of fork-receiving pockets or apertures and including at least one mounting member for non-destructive removable attachment to the collection vehicle lifter.

8. The intermediate container of claim 7 in which each slide member of the rigid extension member has an outwardly-facing roller channel, and each of the spaced-apart side frames of the track assembly includes a plurality of rollers received within a respective one of the roller channels.

9. The intermediate container of claim 7 comprising an openable access panel defining a portion of the container bottom wall, at least a portion of the extension assembly being located below the access panel.

10. The intermediate container of claim 7 including spaced apart mounting members for mounting removably non-destructively the intermediate container to lift arms associated with the lifter of a top loading refuse collection vehicle.

11. The intermediate container of claim 10 in which the mounting members extend generally rearwardly from the intermediate container.

12. The intermediate container of claim 10 further comprising a brace extending rearwardly intermediate the container mounting members for non-destructive removable attachment to a collection vehicle.
