Patent number: 9682484Abstract: A set-up stand is provided including a counterbalance mechanism for use in reconfiguring an end-effector with an articulating portion rotated by a bi-directional rotary locking device, for example, a clutch. A counterbalance mechanism is provided including a holding member which is attached to a preloaded member and connected to an articulating portion of the end-effector during reconfiguration of the end-effector. The preloaded member provides a tension load to counterbalance the gravity moment load of the articulating portion when the articulated portion is rotated in the same direction as the output shaft of the bi-direction rotary locking device, to prevent overhauling, chattering or binding stops during rotation and reconfiguration. A method is provided to utilize the counterbalance mechanism as described.Type: GrantFiled: April 8, 2010Date of Patent: June 20, 2017Assignee: GM Global Technology Operations LLCInventors: Yhu-Tin Lin, Andrew L.
