Patent ID: 7614789

Claim:
A power driven linear operator comprising: a guiding linear body made up of a one piece integral extruded profiled guiding element defining a guide portion with a groove or rail shape, said guide portion extending in a longitudinal direction of said guiding linear body, said extruded profiled guiding element having means for attaching said guiding linear body to a stationary surface to fix said guiding linear body extending along a stationary plane, said extruded profiled guiding element having opposite lateral sides defining a guiding linear body width dimension; a guided movable body made up of a one piece integral extruded profiled guided element defining a guided portion with a groove or rail shape that is complementary to said guide portion to fit together complementarily in a coupled state, said guided moveable body for alternate direction movement along the guide portion, said extruded profiled guided element defining means for attaching the guided movable body to at least one member to be moved alternately, said extruded profiled guided element having a shorter length than said guiding linear body in said longitudinal direction, said extruded profiled guided element having opposite lateral sides defining a guided moveable body width dimension, said guided movable body width dimension being the same as said guiding linear body width dimension with aligned opposite lateral sides in said coupled state; bearings interposed between said guiding linear body and said guided movable body; a pneumatic or electric actuator connected to each of said guiding linear body and said guided movable body to actuate the alternating movements of the movable body on the guiding linear body; a profiled groove defined by said extruded profiled guiding element and extending along each of said opposite longitudinal sides of said guiding linear body and parallel to said stationary plane; and a profiled groove defined by said extruded profiled guided element and extending along each of said opposite longitudinal sides of said guided movable body and parallel to said stationary plane, said profiled groove of said extruded profiled guiding element and said profiled groove of said extruded profiled guided element cooperating in said coupled state to provide collateral grooves that are the same shape, that are parallel and that are positioned in the same plane.
