发明名称 Hand control for manipulating vacuum pickup hose
摘要 <p>A vacuum trash collection vehicle includes a debris container (182) and a source of vacuum (32), both mounted on the vehicle. There is a hose (24) connected at one end to the debris container and the source of vacuum (32) is applied thereto. The opposite end of the hose is open to form a collection nozzle (26). A boom supports (28) the hose during use as a debris collection device. There is a driver accessible control (80) for moving the hose and nozzle which includes an elongated tubular assembly, pivotally mounted at its upper end (86) to the boom (28) and movably mounted at its lower end (104) to the collection nozzle. There is an operator's handle (106), having multiple hand-gripping areas, mounted on the tubular assembly and movable relative thereto during use of the debris collection hose. &lt;IMAGE&gt;</p>
