Rigid multilinear actuator with flexible strand

A multilinear actuator capable of transmitting a pull force and a push force according to at least two different directions, said actuator comprising at least two complementary actuating strands made based on a flexible synthetic material, and provided on a first one of their faces with evenly spaced studs, each stud being provided with two opposite front faces, and with a front transverse active face, with a rear transverse active face, with a longitudinal active face separating the front transverse active face and the rear transverse active face, and with a longitudinal face for connection with the strand, the studs equipping the respective first faces of the two actuating strands located opposite one another mesh with one another, and the front and rear transverse active faces of a stud of one of the actuating strands respectively bear against the respective rear and front transverse faces of two neighboring studs associated to the other actuating strand, while defining a section extending according to a straight line wherein the two actuating strands are securely connected, and the shape and the dimensions of the space comprised between the studs of said actuating strand are complementary to those of the neighboring studs associated to the other actuating strand, segments of the respective first faces of the two actuating strands separating the studs, as well as the longitudinal faces of said studs are provided with notches, the notches of the longitudinal face of one stud of one of the actuating strands cooperating with corresponding notches of the segment of the first face of the other strand located between the two studs associated to said stud by nesting into said corresponding notches when the two actuating strands are securely connected, so that the linear actuator section behaves like a rigid bar in one-piece, said actuating strands comprising evenly spaced teeth on a second one of their faces, opposite to the first face, said actuator comprising a driving member per actuating strand, each driving member meshing with the teeth of the second face of one of said actuating strands to drive said actuating strand in translation, said actuator comprising a first straight section in which the actuating strands are meshed, a second straight section in which the actuating strands are meshed, and a curved region located between the first straight section and the second straight section, in which the actuating strands are spaced apart.
