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 a proximal end and a distal operable end, comprising:

gripping the proximal end of the elongated shaft;

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 distal 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 distal operable end by rotating the proximal end of the extension arm, causing a corresponding rotation in the distal operable end of the extension arm,

wherein the distal operable end includes a plurality of tangs and a plurality of notches separating the plurality of tangs, the turn switch includes a plurality of arms, and engaging includes receivably engaging the plurality of arms of the turn switch in the plurality of spaced notches of the coupling of the operable end so that the plurality of arms extend through the plurality of notches, external to a periphery of the coupling.

2. The method of claim 1, wherein the distal operable end includes a coupling with tangs, and the coupling includes an outer surface and a plurality of reinforcement tangs adhere to the outer surface to reinforce the tangs and prevent the tangs from breaking off from the coupling.

3. The method of claim 1, wherein the distal operable end includes a coupling with tangs, and the coupling includes an outer surface and the distal operable end includes an outer, larger-diameter coupling with outer tangs adhered to the outer surface of coupling to reinforce the tangs and prevent the tangs from breaking off from the coupling.

4. The method of claim 1, wherein the plurality of tangs and the plurality of notches include three tangs and three notches, the turn switch includes three arms, and engaging includes receivably engaging the three arms of the turn switch in the three spaced notches of the coupling of the operable end so that the three arms extend through the three notches, external to a periphery of the coupling.

5. The method of claim 1, wherein the plurality of tangs and the plurality of notches include four tangs and four notches, the turn switch includes four arms, and engaging includes receivably engaging the four arms of the turn switch in the four spaced notches of the coupling of the operable end so that the four arms extend through the four notches, external to a periphery of the coupling.
