Abstract

A vacuum trash collection vehicle includes a debris container and a source of vacuum, both mounted on the vehicle. There is a hose connected at one end to the debris container and the source of vacuum is applied thereto. The opposite end of the hose is open to form a collection nozzle. A boom supports the hose during use as a debris collection device. There is a driver accessible control for moving the hose and nozzle which includes an elongated tubular assembly, pivotally mounted at its upper end to the boom and movably mounted at its lower end to the collection nozzle. There is an operator'"'"'s handle, having multiple hand-gripping areas, mounted on the tubular assembly and movable relative thereto during use of the debris collection hose.

Claims

1. A vacuum trash collection vehicle including a debris container on the vehicle, a source of vacuum on the vehicle, a hose connected at one end to the debris container and having the source of vacuum applied thereto, said hose being open at its other end to form a collection nozzle, a boom for supporting said hose during use as a debris collection device,

driver accessible control means for moving said hose and nozzle including an elongated tubular assembly, pivotally mounted at its upper end to said boom and movably mounted at its lower end to said collection nozzle, and an operator'"'"'s handle mounted on said tubular assembly and movable relative thereto during the use thereof.

2. The vacuum trash collection vehicle of claim 1 wherein said hose collection nozzle mounts a support member thereon, said support member being movable relative to said collection nozzle, and a pivotal connection between said support member and said elongated tubular assembly.

3. The vacuum trash collection vehicle of claim 2 wherein the pivotal connection between said elongated tubular assembly and said support member includes a fork attached to said tubular support assembly and pivotally mounted to said support member.

4. The vacuum trash collection vehicle of claim 3 wherein said movable support member is a ring.

5. The vacuum trash collection vehicle of claim 1 wherein the pivotal mounting of said elongated tubular assembly to said boom includes a support arm extending outwardly from said boom in a direction transverse to vehicle movement.

6. The vacuum trash collection vehicle of claim 5 wherein said support arm is mountable to extend outwardly from said boom either in a left direction or a right direction transverse to vehicle movement.

7. The vacuum trash collection vehicle of claim 1 wherein said operator'"'"'s handle includes a tubular portion mounted on said tubular assembly and rotatable relative thereto.

8. The vacuum trash collection vehicle of claim 7 wherein the position of said handle tubular portion on said tubular assembly is adjustable along the length of said tubular assembly.

9. The vacuum trash collection vehicle of claim 7 wherein said operator'"'"'s handle includes multiple hand-gripping areas attached to said tubular portion.

10. The vacuum trash collection vehicle of claim 9 wherein said tubular portion forms a hand-gripping area.

11. The vacuum trash collection vehicle of claim 9 wherein said multiple hand-gripping areas include hand-gripping areas extending laterally from said tubular portion and a hand-gripping area extending generally perpendicular to said lateral hand-gripping areas.

12. The vacuum trash collection vehicle of claim 11 wherein said lateral hand-gripping areas and said hand-gripping area extending generally perpendicular thereto are joined together at one end thereof, with the opposite ends being connected to said tubular portion.

13. The vacuum trash collection vehicle of claim 1 wherein said collection nozzle includes a guard ring attached thereto, said guard ring being spaced from the hose open end.
