ABSTRACT:
A flexible coiled linear actuator linkage is disclosed. The linkage couples the piston rod of a linear actuator to a rotatable control arm having a pivot axis perpendicular to the longitudinal movement of the piston rod during its power stroke. The linkage is threaded onto the piston rod of the linear actuator for a positive anchorage at one end and is secured by a connection loop onto a thrust lever of the control arm at the other end. During a positive displacement of the piston rod, the linkage transforms the longitudinal linear motion of the actuator into a pivotal rotary motion by a bending flexure of its body. A plurality of release loops for facilitating the disassembly of the connection between the actuator and the control arm are further provided according to another aspect of the invention.
