Grasping devices including arms pivotally connected to a support member and moved by actuators pivotally connected between the arms and the support member are described. The arms may be either single or multiple member limbs shaped to engage a variety of geometrically shaped objects. Multiple member embodiments include an outer member pivotally connected to an inner member which is pivotally connected to the support member. Each arm may carry a suction cup. The support members of each embodiment may be connected to any lifting device, such as a compound arm attached to a refuse truck.

[ What is claimed is:] [1.] A fully retractable material handling apparatus for grasping and releasing a container comprising:(a) a support member for carrying a pair of opposed arms and having an outer edge defining a corresponding container-receiving surface;(b) a pair of opposed arms aligned in spaced relation for grasping and releasing a container of interest wherein each arm of said pair of opposed arms comprises a plurality of sequentially segmented members including an inner member and an outer member, each of said inner members having a first end pivotally connected to said support member at a first point and a second end pivotally connected to a first end of a corresponding outer member at a second point, each of said outer members having a free end, and wherein said sequentially segmented members are capable of conforming to various shapes;(c) a mechanized actuating means for operating said pair of opposed arms between a retracted position and a grasping position;(d) wherein in said grasping position, said sequentially segmented members extend outward beyond said container receiving surface to grasp a container and hold a grasped container against said container-receiving surface of said support member and wherein in said retracted position said sequentially segmented members are opened to a position such that said free ends of said outer members retract behind and do not protrude outward beyond said corresponding container-receiving surface of said support member;(e) wherein said mechanized actuating means for operating said pair of opposed arms comprises a first actuating means including a pair of inner linear actuators each connected between said support member and a corresponding inner member of one arm of said pair of opposed arms and further comprising a second actuating means including a pair of outer linear actuators each connected between said inner member and a corresponding outer member of one arm of said pair of opposed arms, each arm thereby having an inner and an outer linear actuator, said first and second actuating means cooperating to operate said inner and outer members of said pair of opposed arms between a retracted position and a grasping position; and wherein said inner and outer linear actuators of each said arms are connected at a common pivot point between said actuators; and(f) wherein said container-receiving surface includes both contoured and planet elements to receive containers having a plurality of geometries.
