Linear actuator

A modular assembly comprising a plurality of pairs of interlocking linear actuators, wherein each actuator of said pairs of interlocking linear actuators comprises:

• an actuator body;
• an axially displaceable shaft having a longitudinal axis and guided by the actuator body to be axially displaceable relative thereto in the direction of the longitudinal axis of the axially displaceable shaft;
• and
• a drive motor supported by the actuator body and operable to axially displace the shaft relative to the actuator body in two mutually opposite directions, the actuator body of each linear actuator having two mutually opposite sides respectively extending in two parallel spaced-apart planes which each represent a reference plane for positioning the actuator body in a side-by-side relationship with the actuator body of one of the actuators of another pair of interlocking actuators of the assembly, and
• a further side connecting the two mutually opposite sides and stepped to form a projection, through which the axially displaceable shaft passes with said longitudinal axis parallel to the two parallel spaced-apart planes so as to be guided in axial displacement and a rebate beside the projection, to permit the actuator body to be positioned at said further side in interlocking relationship with the actuator body of the other actuator of the respective pair,
• wherein the projection has a projection width that is the same as the rebate width with respect to the spacing of the two parallel spaced-apart planes and the axially displaceable shaft is disposed centrally of the projection to configure the pitch of the longitudinal axes of the axially displaceable shafts of each pair of interlocked actuators to be equal to said width.
