Abstract

A method of operating at least one of a fan and a vent in a ceiling of a recreational vehicle using an extension arm, the extension arm including an elongated shaft with an operable end, comprising grabbing the extension arm with one'"'"'s hand; engaging one of a turn switch, a turn crank, and a knob of one of the fan and vent in the ceiling of the recreational vehicle with the operable end; and at least one of operating the fan and vent by rotating one of the turn switch, the turn crank, and the knob with the operable end by rotating the extension arm with one'"'"'s hand.

Claims

1. A method of operating at least one of a fan and a vent in a ceiling of a recreational vehicle using an extension arm, the extension arm including an elongated shaft with an operable end, comprising:

engaging one of a turn switch, a turn crank, and a knob of one of the fan and vent in the ceiling of the recreational vehicle with the operable end;

at least one of operating the fan and vent by rotating one of the turn switch, the turn crank, and the knob with the operable end by rotating the extension arm,

wherein the operable end includes a coupling attached to the extension arm, the coupling including an axial center coaxial with an axial center of the extension arm, the coupling including a periphery, at least three tangs on the periphery, and at least three corresponding notches on the periphery and forming openings at the periphery, each of said at least three tangs extending circumferentially around the coupling, and engaging includes engaging one of the turn switch, the turn crank, and the knob with said at least three tangs whereby one of the turn switch, the turn crank, and the knob extends through the openings formed by notches, external to the periphery of the coupling.

2. The method of claim 1, wherein the turn switch includes a plurality of arms and engaging includes receiving the plurality of arms in the at least three notches.

3. The method of claim 1, wherein the turn switch includes four arms, the at least three tangs include four tangs, and the at least three notches include four notches, and engaging includes receivably engaging the four arms of the turn switch in the four spaced notches of the coupling of the operable end.

4. The method of claim 2, wherein the coupling with tangs include an outer surface and a plurality of reinforcement tangs adhered to the outer surface to reinforce the tangs and prevent the tangs from breaking off from the coupling.

5. The method of claim 2, wherein the coupling with tangs include an outer surface and the operable end includes an outer, larger-diameter coupling with tangs adhered to the outer surface of coupling with tangs to reinforce the tangs and prevent the tangs from breaking off from the coupling.

6. The method of claim 1,

wherein the extension arm includes a circular end with an O-ring thereon, and the method further includes receiving a fan switch in the circular end and pressing the fan switch with the O-ring to operate a fan in the ceiling of the recreational vehicle.

7. The method of claim 1, wherein the extension arm includes an end with a cap, and the method further includes pressing a fan switch with the cap to operate a fan in the ceiling of the recreational vehicle.

8. The method of claim 1, wherein the turn crank includes a single turn crank arm, and engaging includes receivably engaging the single turn crank arm within one of the plurality of notches.

9. The method of claim 1, wherein the turn crank includes a pair of arms extending linearly in opposite directions from each other, and engaging includes receivably engaging the pair of arms within two respective notches of the plurality of notches.

10. A method of operating at least one of a fan and a vent in a ceiling of a recreational vehicle using an extension arm, the extension arm including an elongated shaft with an operable end, comprising:

engaging one of a turn switch, a turn crank, and a knob of one of the fan and vent in the ceiling of the recreational vehicle with the operable end;

at least one of operating the fan and vent by rotating one of the turn switch, the turn crank, and the knob with the operable end by rotating the extension arm,

wherein the extension arm includes a second operable end including one of

a coupling including a plurality of tangs,

a coupling including a plurality of tangs and a plurality of spaced notches separating the plurality of tangs,

a coupling including a plurality of tangs, an outer surface, and a plurality of reinforcement tangs adhered to the outer surface,

a coupling including a plurality of tangs, an outer surface, and an outer, larger-diameter coupling with tangs adhered to the outer surface of coupling with tangs, a circular end with an O-ring thereon, an end cap, and

a coupling including an open-ended vent knob control member having a plurality channels, a plurality of notches,

and the method further comprising

engaging one of a turn switch, a pressable switch, a turn crank, and a knob of one of the fan and vent in the ceiling of the recreational vehicle with the second operable end; and

at least one of

operating the fan and vent by one of rotating one of the turn switch, the turn crank, and the knob with the second operable end by rotating the extension arm, and

pressing the pressable switch with the second operable end by raising the extension arm.

11. The method of claim 10, wherein the method includes engaging and operating one of the turn switch, the turn crank, and the knob with the operable end followed by engaging and operating one of the turn switch, the turn crank, and the knob with the second operable end.
