Patent ID: 8256323

Claim:
A manual control device comprising: a handle extending along a handle axis; a trigger mobile in rotation about a trigger axis with respect to the handle; a pressure part disposed at an end of the trigger, wherein the pressure part has an actuation surface centered on an actuation surface center, which receives a thumb of a hand grasping the handle; a first trigger stop delimiting trigger rotation in a first direction; a first trigger position defined by delimiting contact between the trigger and the first trigger stop; a second trigger stop delimiting trigger rotation in a second direction; a second trigger position defined by delimiting contact between the trigger and the second trigger stop; a first reference plane including the handle axis and extending parallel to the trigger axis; a second reference plane including the trigger axis and extending perpendicular to the first reference plane; a handle cross point defined by the intersection of the handle axis and the second reference plane; a first normal plane extending perpendicular to the handle axis and including the actuation surface center when the trigger is in the first trigger position; and a second normal plane extending perpendicular to the handle axis and including the actuation surface center when the trigger is in the second trigger position, wherein the handle cross point is located between the first normal plane and the second normal plane.
