Abstract
Apparatus and methods for remote (at a distance) actuation of points of control, such as valves and switches. Controlling a switch or valve at a distance is achieved by a support member having a movable portion, with the moveable portion including an elongate member, and a drive mechanism in communication with the moveable portion. A motor, hand crank, or other force transmission apparatus acts to move the drive mechanism and thus the movable portion and elongate member such that a valve or switch is actuated at a distance.
Claims24
A point of control remote-actuation apparatus, comprising:
- a support member having a rotatable portion, said rotatable portion including a holder configured to engage an elongate member along any portion of a length of said elongate member and such that a first end and a second end of the elongate member are free of contact with said point of control remote-actuation apparatus,
- a drive mechanism in communication with said rotatable portion, said drive mechanism adapted to rotate said rotatable portion and elongate member engaged by said holder in response to a motive force, wherein said drive mechanism is offset from the holder such that the drive mechanism and holder are not in axial alignment;
- and a load measurement indicator that indicates torque versus rotational position as a proxy for operation status.
A point of control remote-actuation apparatus, comprising:
- an elongate member having a first end and second end,
- a support member having a movable portion, said moveable portion being adjustably coupled with said elongate member along any portion of a length of said elongate member such that said first end and said second end of the elongate member are free of contact with said point of control remote-actuation apparatus during an actuation operation;
- and
- a drive mechanism in communication with said moveable portion, said drive mechanism configured to provide movement to the moveable portion and elongate member in response to a motive force, wherein said drive mechanism is offset from the movable portion such that the drive mechanism and movable portion are not in axial alignment, and wherein said movable portion moves said elongate member linearly or rotationally to operate said point of control at a distance.
A method for operating a point of control at a distance with a remote-actuation apparatus, said apparatus including an elongate member coupled with a movable portion of a support member along any portion of a length of said elongate member and such that a first end and a second end of the elongate member are free of contact with said remote-actuation apparatus, with said support member having a drive mechanism that is offset from the movable portion such that the drive mechanism and movable portion are not in axial alignment, comprising the step of:
- actuating said drive mechanism such that said movable portion moves said elongate member and thereby operates said point of control at a distance.
