DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to FIGS. 1-13, an embodiment of an extension arm or extender 100 that allows people to reach cranks and switches in RV ceilings to operate the vents and fans in the RV ceilings will be described.

The extension arm 100 includes an elongated cylindrical pipe or shaft 110, a first operable end 120, and an opposite second operable end 130. In the embodiment shown, the pipe 110 is 1 in. PVC plastic pipe that is 24 in. in length. In alternative embodiments, the shaft 110 includes one or more of alternative constructions, configurations, materials, lengths, diameters, and/or dimensions.

As shown best in FIG. 2, the first operable end 120 includes a cylindrical coupling 140 that is attached (e.g., by adhesive such as glue) at the first operable end 120. In an alternative embodiment, the first operable end 120 does not include the coupling 140. A distal end of the coupling includes four substantially rectangular, tooth-shaped tangs 150 spaced evenly by notches 160. The tangs 150 extend distally from the first operable end 120, parallel with a central longitudinal axis defined by the cylindrical pipe 110. A rubber O-ring 170 is attached to a terminal end of the cylindrical pipe 110 at the first operable end 120, circumferentially interior to the coupling 140. In the embodiment shown, the height of each tang 150 is ⅜ in. and the width of each tang 150 is 5/16 in. and the straight-line distance between tangs 150 or straight-line width of each notch 160 is ¾ in. In the embodiment shown, the rubber O-ring 170 is 1⅙ in. in diameter, 15/16 in. in with, and ⅛ in. in height. In the embodiment shown, the height of coupling 140 (from the proximal end to the base of the tangs 150) is 1⅛ in.

FIGS. 9 and 10 show further embodiments of operable ends 171, 172 similar to first operable end 120. Like elements will be shown and described with like reference numbers, but with an “a” and “b” suffix. In FIG. 9, the operable end 171 includes reinforcement tangs 173 that are adhered to an outer surface 174 of the coupling 140a and tangs 150a, reinforcing the tangs 150a and prevent them from snapping/breaking off from the coupling 140a. The reinforcement tangs 173 extend the height/length of the operable end 171 (i.e., the combined height of the coupling 140a, including tangs 150a). In FIG. 10, the operable end 172 includes an outer, larger-diameter coupling 175 with tangs 176, which slides over and adheres to the outer surface of inner, smaller-diameter coupling 140b with tangs 150b, reinforcing the tangs 150b and prevent them from snapping/breaking off from the coupling 140b.

As shown in FIG. 3, the second operable end 130 includes a first notch 180, a second notch 190, and a third notch 200. The first notch 180 and the second notch 190 separates a first tang 210 from a third tang 230 and a second tang 220 from a third tang 230. In the embodiment shown, the first notch 180 and second notch 190 are 180 degrees apart. The height of the first notch 180 and second notch 190 is 5/16 in. and the height of the third notch 200 is 1.2 in. The width of the first notch 180 and second notch 190 is ⅛ in. and the width of the third notch 200 is 0.5 in.

With reference to FIGS. 4-8, and initially FIGS. 4 and 8, the extension arm 100 will now be described in use. To turn on or off a fan 250 in a ceiling 252 of a RV 254, a user 240 grabs the extension arm 100 near the second operable end 130 and lifts the extension arm 100 upward so as to reach, engage, and operate a fan switch 260 with the first operable end 120. The fan switch 260 is engaged so that the four arms 270 (in a cross-shaped configuration) are receivably engaged respectively by the four evenly spaced notches 160 of the cylindrical coupling 140 at the first operable end 120. To turn on the fan 250, the fan switch 260 is rotated clockwise by the first operable end 120 by rotating the second operable end 130. Because the first operable end 120 is fixed relative to the second operable end 130, rotation of the second operable end 130 causes corresponding rotation in the first operable end 120, causing the fan switch 260 to rotate accordingly. Rotation of the fan switch 260 clockwise turns on the fan 250 and rotation of the fan switch 260 counter clockwise turns off the fan 250.

With reference to FIG. 5, to turn on/off a fan 280 including a push-button switch 290 in the RV ceiling, the user 240 handles the extension arm 100 in a similar manner to that discussed above with respect to FIG. 4, except that the first operable end 120 is used to push on and off the push-button switch 290. The coupling 140 of the first operable end 120 is fit over the push-button switch 290 and a front face of the push-button switch 290 is engaged by a distal face of the rubber O-ring 170 to push on and off the push-button switch 290. With reference to FIG. 11, in another embodiment, an operable end 291 includes a cap 292 that slides over and adheres to an outer surface 293 of the extension arm 100. The front face of the push-button switch 290 is engaged by end wall 294 of the cap 292 of the operable end 291 to push on and off the push-button switch 290.

With reference to FIG. 6, to open/close a vent 300 in a ceiling 252 of a RV 254, a user 240 grabs the extension arm 100 near the first operable end 120 and lifts the extension arm 100 upward so as to reach, engage, and operate a turn crank 310 with the second operable end 130. The turn crank 310 is engaged so that single turn crank arm 320 extending from turn crank shaft 325 is receivably engaged by third notch 230 at the second operable end 130. To open the vent 300, the turn crank 310 is rotated clockwise by the second operable end 130 by rotating the first operable end 120. Rotation of the turn crank 310 clockwise opens the vent 300 and rotation of the turn crank 310 counter clockwise closes the vent 300.

With reference to FIG. 7, to open/close a vent 330 in a ceiling 252 of a RV 254, a user 240 grabs the extension arm 100 near the first operable end 120 and lifts the extension arm 100 upward so as to reach, engage, and operate a turn crank 340 with the second operable end 130. The turn crank 340 is engaged so that a pair of arms/wings/blades 350, 360 extending outward linearly in opposite directions from turn crank shaft 370 are receivably engaged respectively by first notch 180 and second notch 190 at the second operable end 130. To open the vent 330, the turn crank 340 is rotated clockwise by the second operable end 130 by rotating the first operable end 120. Rotation of the turn crank 310 clockwise opens the vent 330 and rotation of the turn crank 310 counter clockwise closes the vent 330.

With reference to FIGS. 12 and 13, another embodiment of an operable end 380 of the extension arm 100 is used to open/close a vent 330 in a ceiling 252 of a RV 254. The operable end 380 includes a first cylindrical coupling 382 that slides over and may be adhered to an outer surface 293 of the extension arm 100. A second cylindrical coupling 384 slides over and may be adhered to an outer surface of the first cylindrical coupling 382. In an alternative embodiment, the first cylindrical coupling 382 and the second cylindrical coupling 384 may be a single integrated coupling member instead of be two separate coupling members 382, 384. The second cylindrical coupling 384 includes an open-ended window/vent knob control member 386. The window/vent knob control member 386 includes a plurality (e.g., six) of recesses/channels 388 that receive corresponding protruding portions 390 of window/vent knob 400 to engage and turn the window/vent knob 400 clockwise and counter clockwise to open/close the vent 330.

Thus, the extension arm 100 (via the operable ends 120, 130, 171, 172, 291, 380) enables a user 240 to reach and/or operate the turn switches 260, 290, the crank arms 310, 340, and the window/vent knob 400 in the ceilings of RVs 254 to operate the fans 250, 280 and vents 300, 330 in the ceilings of RVs 254. The extension arm 100 and the operable ends 120, 130, 171, 172, 291, 380 eliminate the need for short ladders/step stools to reach and operate the turn switches 260, 290, the crank arms 310, 340, and the window/vent knob 400 in the ceilings of RVs 254. Eliminating the need for short ladders/step stools eliminates the risk of the user falling and hurting oneself and eliminates the extra storage space requirements of short ladders/step stools. In one or more embodiments, one end of the extension arm 100 includes operable ends 120, 130, 171, 172, 291, or 380 and a second, opposite end of the extension arm 100 includes operable ends 120, 130, 171, 172, 291, or 380.
