The rewind starter is accessible through a hole formed in the side panel.
Description
- This application claims the benefit of priority to U.S. Provisional Application No. 60/430,096, titled “SIDE PANEL FOR A SNOWMOBILE,” filed Dec. 2, 2002, which is incorporated by reference herein in its entirety.
- 1. Field of the Invention
- This invention relates to the fairings, engine covers, and rider supports of vehicles such as snowmobiles.
- 2. Description of Related Art
- Unless otherwise expressly stated, all dimensions for snowmobile riders are based on a standard rider, who is defined by a 50th-percentile United States human male who weighs 78 kilograms (174.8 lb.) and has the dimensions shown in FIGS. 7 and 8. As would be obvious to one of ordinary skill in the art, the dimensions illustrated in FIGS. 7 and 8 are in centimeters with the middle values representing the 50th-percentile U.S. human male. Similarly, all positioning of the riders is based on the positioning of a standard rider on a snowmobile in a standard position. In the standard position, the rider is seated on the seat, is holding the steering device with his hands, and has his feet on the footrest. Accordingly, the rider has the position shown in the Figures (i.e., in the approximate position of a rider a few seconds after starting the vehicle, heading straight ahead on a flat terrain).
- As illustrated in FIG. 9,
conventional snowmobiles 10 share a common construction: they combine features and elements so that thesnowmobile rider 20 sits in a generally upright position on aseat 30 in a location toward the rear of thesnowmobile 10. When therider 30 is seated in this generally-relaxed fashion, theseat 30, afootrest 40, and a steering device (such as a handlebar) 50 support all of the forces that therider 30 exerts on thesnowmobile 10. - The

Thetunnel 235 supports afootrest 290 that is constructed to support the feet of thestandard snowmobile rider 300. - Elements of the snowmobile200 (such as, for example, the
seat 220,frame 210,footrest 290, and steering device 280) are positioned relative to each other so that thestandard snowmobile rider 300 who is sitting on theseat 220 in a standard riding position is positioned farther forward on thesnowmobile 200 than thesnowmobile rider 30 is on the conventional snowmobile 10 (FIG. 9). Furthermore, therider 300 is preferably positioned in a more active riding position that improves the rider's ability to raise and lower himself using his legs, absorb bumps, and lean into turns. - The inventors of the present invention realized that when the
rider 300 is in the position shown on thesnowmobile 200, thesnowmobile 200 could be designed to further improve the rider's comfort, control, and active positioning if thesnowmobile 200 directly supported the rider's lower leg (e.g., his knee, inner leg/thigh, tibia, and/or shin). Accordingly, as described below, thesnowmobile 200 is constructed and arranged to support the lower leg of therider 300. - As shown in FIG. 1, a
front fairing 305 andcontrol console 310 enclose an upper side of themotor 230. The fairing 305 is preferably rigidly mounted to theframe 210, but may alternatively be removably mounted to theframe 210 so as to enable easy access to the top of themotor 230. Amotor pan 315 is mounted to theframe 210 below themotor 230 to protect and enclose the underside of themotor 230. - As shown in FIGS.1-3, right and
left side panels 320 pivotally connect to theframe 210 at side panel pivot axes 330 such that each of theside panels 320 have open and closed positions relative to theframe 210. Because the left andright side panels 320 are generally mirror images of each other, only theright side panel 320 is described in detail. It is to be understood, however, that aside from the noted exceptions (for example, only theright side panel 320 has a rewind starter hole 440), the description of theright side panel 320 also applies to theleft side panel 320. - As shown in FIGS. 1 and 2, when the
side panel 320 is closed, it encloses and protects a lateral side of themotor 230. An upper edge of theside panel 320 preferably mates with a side edge of thefairing 305 and/orconsole 310. Similarly, a lower edge of theside panel 320 preferably mates with a side edge of themotor pan 315. Consequently, when theside panels 320 are closed, theside panels 320, motor pan 325,console 310, and fairing 305 protect and enclose themotor 230. - As illustrated in FIG. 3, when the
side panel 320 is opened, a lateral side of themotor 230 andother snowmobile 200 components are accessible. As illustrated in FIG. 2, thesnowmobile 200 includes alatch mechanism 340 that selectively holds theside panel 320 in its closed position. In the illustrated embodiment, thelatch mechanism 340 comprises upper and lower latches. However, a variety of alternative fastening devices (e.g., cotter pins, bolts, straps, etc.) may be used without departing from the scope of the present invention. - As shown in FIG. 1, to enable the
side panel 320 to swing generally horizontally between its open and closed positions, the sidepanel pivot axis 330 preferably extends in a generally vertical direction. Accordingly, an angle a formed between the sidepanel pivot axis 330 and a vertically extendingline 350 is preferably less than 45 degrees and is more preferably less than 30 degrees. The angle a is preferably about 19 degrees. - While the illustrated
side panel 320 mounts to theframe 210 through a pivotal connection and alatch mechanism 340, theside panel 320 may alternatively mount to theframe 210 via a variety of alternative fasteners (e.g., a plurality of latch mechanisms, straps, etc.). Theside panel 320 may alternatively be removably mounted to theframe 210. Theside panel 320 may alternatively be permanently rigidly mounted to theframe 210 such that theside panel 320 may not be opened. In such an embodiment, alternative means for accessing themotor 230 should be included (e.g., a removable top fairing such as themotor cover 100 shown in FIGS. 9 and 10, etc.). - As illustrated in FIGS.2-6, the
right side panel 320 includes first, second, and thirdside panel portions side panel portions side panel 320 may alternative comprise a variety of other strong, light, materials such as gel-coated fiberglass, etc. Alternatively, each of theside panel portions side panel portions - A forward end of the first
side panel portion 360 pivotally connects to the frame about thepivot axis 330. As illustrated in FIG. 6, a plurality oftabs 361 that are disposed on the forward end of the firstside panel portion 360 form part of a hinge or other type of pivotal connection that defines thepivot axis 330. As shown in FIG. 5, the firstside panel portion 360 is generally vertically oriented and extends rearwardly from thepivot axis 330. The firstside panel portion 360 provides a majority of the side enclosure for themotor 230. - As shown in FIGS. 2 and 4, the second
side panel portion 370 extends laterally inwardly from a rearward end of the firstside panel portion 360. The secondside panel portion 370 includes awind deflector 390 toward its upper end. A removable padded knee rest, which may be formed as part of thewind deflector 390, may be applied to an upper portion of theside panel portion 370 to increase the comfort to the driver. The knee rest is preferably positioned at or near where the knee of therider 300 is positioned during operation of thesnowmobile 200. Accordingly, therider 300 may lean forward (relative to the rider position illustrated in FIG. 1) to support his knees on the knee rest. Similarly, a lower portion of the secondside panel portion 370 defines a lowerfront leg support 395 that is adapted to support the front of the rider's lower leg (e.g., the rider's shin or tibia). - The second
side panel portion 370 is constructed and arranged to be at least slightly wider than the rider's legs and extend laterally outwardly beyond the rider's legs when therider 300 is in the standard riding position. Consequently, the rearward end of the first side panel portion is disposed laterally outwardly from the rider's legs and deflects wind, snow, and other debris away from the rider's legs during the operation of thesnowmobile 200. - As shown in FIGS. 2, 4, and5, the third
side panel portion 380 is generally vertically oriented and extends rearwardly from an inner lateral end of the secondside panel portion 370. The thirdside panel portion 380 preferably defines aninner leg support 400 that is constructed and arranged to be disposed at or near the rider's inner legs or thighs. Accordingly, therider 300 may help position himself by pushing his legs laterally inwardly against theinner leg support 400. - Together, the knee rest, lower
front leg support 395, andinner leg support 400 of theside panel 320 define alower leg support 410. Thelower leg support 410 improves the rider's comfort and ability to actively position himself. Any one of the knee rest, lowerfront leg support 395, andinner leg support 400 may be omitted from thelower leg support 410 without deviating from the scope of the present invention. - As illustrated in FIG. 2, a lower part of the
latch mechanism 340 secures the lower part of the secondside panel portion 370 to theframe 210. Similarly, an upper part of thelatch mechanism 340 secures an upper part of the thirdside panel portion 380 to theframe 210. The latch mechanism is preferably recessed relative to the outer surface of the second and thirdside panel portions side panel 320. Thelatch mechanism 340 may alternatively connect between other portions of theside panel 320 andframe 210 without deviating from the scope of the present invention. - In the illustrated embodiment, the integrally formed
side panel portions side panel portions side panel 320 can effectively withstand the loads exerted by therider 300 on thelower leg support 410 without the need for additional reinforcing structures in the area of thelower leg support 410. Theside panel 320 transfers the forces exerted on thelower leg support 410 to the frame through thelatch mechanism 340 and the pivotal connection formed between theside panel 320 and theframe 210. - Alternatively, the first
side panel portion 360 may be formed separately from the second and thirdside panel portions side panel portion 360 would pivot relative to theframe 210 to enable access to themotor 230. The second and third side panel portions could rigidly mount to the frame. Because the first and second side panel portions would be latched together, rather than integrally formed, the secondside panel portion 370 might less effectively transfer knee loads to the firstside panel portion 360 andframe 210. Accordingly, additional reinforcing structures may need to be provided between theframe 210 and the secondside panel portion 370 to ensure that thelower leg support 410 is rigid enough to withstand the forces exerted on it by therider 300. - In the embodiment illustrated in FIG. 3, the
motor 230 is an internal combustion engine that includes an electric starter (not shown). In case the electric starter fails, however (due to battery discharge, etc.), a rewind starter 420 (FIG. 3) is also provided. Therewind starter 420 includes acord 425 and ahandle 430. As shown in FIGS. 2 and 6,hole 440 is formed in the thirdside panel portion 380 to enable therider 300 to access and use therewind starter 420 without opening theside panel 320. Thehole 440 is preferably defined bysides 445 that are recessed relative to an outer surface of thethird panel portion 380. When therewind starter 420 is in its rewound position, thehandle 430 preferably does not extend outwardly past the outer surface of the thirdside panel portion 380. Accordingly, thestarter handle 430 does not interfere with the rider's comfortable use of the thirdside panel portion 380 as theinner leg support 400. - While the
hole 440 is disposed in the thirdside panel portion 380 of theleft side panel 320 in the illustrated embodiment, thehole 440 and accompanying starter handle 430 may alternatively be positioned in a variety of other locations. For example, therewind starter 420 may be disposed on the right side of thesnowmobile 200 and the accompanyinghole 440 may be disposed on theright side panel 320. Furthermore, thehole 440 may be positioned in any part of the side panel 320 (e.g., in the first or secondside panel portions side panel portions - While preferred embodiments of the invention have been shown and described with reference to the accompanying figures, it is evident that variations and modifications are possible that are within the spirit and scope of the preferred embodiments described herein. In addition, while the side panel has been described with reference to use with a snowmobile, most if not all the features of the side panel could be applied to other environments as well, such as for other vehicles, or for securing members that are movable with respect to one another.
