Patent ID: 7753748

Claim:
A control device comprising: a control member regulating operating conditions of an operating unit, the control member being movable along a predetermined path and for a predetermined range between two extreme stop positions, the control member comprising a handle extension movable between an operative position, wherein the handle extension is deployed, and a non-operative position, wherein the handle extension is disposed within at least a portion of the control member, thereby reducing overall dimensions of the control member; a first part fixedly couplable to a support structure; and a second part rotatably coupled to the first part, an angular displacement of the second part in relation to the first part determining a corresponding change in the operating conditions of the operating unit, the handle extension being coupled to the second part and acting as a lever when in the operative position, wherein the control device is couplable to a linkage, a tie rod system, or a displacement, position, electric, or electronic sensor, by which a movement of the control member regulates the operating conditions of the operating unit, wherein the handle extension is coupled with a hinge to one end of the second part, thereby providing an open and closed position in relation to the second part, wherein the non-operative position corresponds to the closed position in which the handle extension is disposed on the second part, and wherein the operative position corresponds to the open position in which the handle extension extends outwardly and is operable as the lever.
