发明名称 Material pickup device
摘要 There is disclosed a device for picking up litter, small articles and the like, comprising a pair of handle members having a receptacle mounted on one of the members and a pusher mounted on the other. The handle members are pivotally connected to allow movement of the pusher toward the receptacle. The pivot axis defining handle movement is positioned such that the pusher describes a long, flat arc in front of the receptacle with the low point of the arc being somewhat in front of the receptacle. Appropriate positioning of the pivot axis is accomplished by offsetting the upper ends of the handle members in a direction toward the pusher. There is also disclosed an improved spring-hinge construction and means for disassembling the device for replacing the spring. In addition, there is disclosed an adjustable frame for supporting receptacles of different sizes.
