## Background
RELATED APPLICATION
This is a continuation of U.S. patent application Ser. No. 10/889,802, filed Jul. 13, 2004, titled Vehicle Expansion Retainer, now U.S. Pat. No. 7,055,454 issued Jun. 6, 2006 and herein incorporated by reference in its entirety.


FIELD
This disclosure relates to powered vehicles and more particularly to snowmobiles, all terrain vehicles (ATV), personal watercraft, utility vehicles (UV), motorcycles having surfaces to hold accessories, and more specifically fastening accessories to a vehicle accessory platform.
BACKGROUND
Current accessory latching systems require bolting the accessory to the rack, a process that can require a significant amount of time and effort. Generally this requires taking a plate, such as a steel flat plate, and placing it on the bottom side of an ATV rack, such as a steel tube rack or a composite rack, and then sandwiching the rack with another plate on top of the rack and fastening the two plates together with U-bolts or some other type of fastener. An accessory can then be mounted to the rack above or to the top plate. This system is expensive and the mounting process is very laborious and time consuming. Further, the inaccessibility to the bottom side of the rack plus the amount of time it takes putting the plate on the bottom and running bolts up through the bottom plate made this system undesirable. Other accessory latching systems utilize a receiver style mount in the rack, which receives a pin or the like which is then fastened to the accessory. In this system the receiver style mount must often be cleared of dirt and other materials due to the environment the ATV can be used in before the pin can be inserted. Other accessory latching systems utilize a handle that goes through the rack then the operator reaches under the rack and turns a spring loaded distal end so it is perpendicular to the axis of the hole thus preventing the removal of the handle. The handle is then attached to the accessory. Once again this system requires the operator to perform several steps to mount the accessory.
Attaching accessories or any other item to an ATV needs to be cost effective and simple. These latching systems must also be able to handle the rigor and generally “dirty” environment that an ATV is designed for. The capability to quickly attach and remove an item from the rack will significantly improve the quality and functionality of the accessories.

FIG. 1D depicts a snowmobile of the teachings. The snowmobile includes a chassis 31, a straddle type seat 32 mounted to the chassis 31, and a pair of handlebars 34 carried by the chassis 31 adjacent to the seat 32 so that a rider sitting in straddle fashion on the seat may steer the snowmobile using the handlebars 34. The snowmobile includes an endless track 36 carried by a rear suspension system 38 mounted to the chassis 31, the endless track being connected to and powered by the snowmobile's engine 35 (typically located beneath the hood near the front of the snowmobile). A fuel tank may be located under seat 32.
Left and right steerable skis 50 are carried by a front suspension system 40, which in turn is mounted to the chassis 31. The suspension system may be of any suitable type. In the drawings a trailing arm suspension system is depicted, such a system utilizing, for each ski, a trailing arm 42 connected at its rear end to the chassis, a pair of generally transversely mounted radius rods 43 connected at their inner ends to the chassis and at their outer ends to the front end of the trailing arm, and a shock/spring combination 44 connected at one end to the chassis 31 and at the other end to the front end of the trailing arm 42. Other suitable suspensions could also be utilized, however, including, e.g., a double A-arm (sometimes called “double wishbone”) suspension or a telescopic strut suspension. Snowmobile 30 can also have mounting aperture 60 (FIG. 12) located anywhere on snowmobile 30, such as luggage rack 62.
With reference to FIG. 1E, a perspective view of a personal watercraft that can incorporate some embodiments of the present teachings is shown. FIG. 1E illustrates a personal watercraft 820 having generally a front or bow 822 and a rear or stern 823. The personal watercraft 820 includes a top deck 826 secured to a bottom hull 824 along an overlapping portion covered with a rub rail 832 in the embodiment illustrated, thereby forming a hull. An exhaust opening (not shown) can be located in top deck 826 or in bottom hull 824. The hull formed by the bottom hull 824 and top deck 826 define a compartment sized to contain an internal combustion engine 833 for powering the watercraft, and may also include one or more storage compartments, depending upon the size and configuration of watercraft 820. The deck portion 826 also has a raised, longitudinally extending seat 828 adapted to accommodate one or more riders seated in straddle fashion on the seat 828.
Engine 833 powers a jet propulsion unit 834, typically mounted in a tunnel at the bottom rear portion of watercraft 820. Jet propulsion unit 834 includes a steerable water discharge nozzle 331 that is operatively connected to a set of handlebars 842 to facilitate steering of watercraft 820 by the operator. Engine 833 may be of the two or four cycle variety. Of course, engine 833 may have one or more cylinders, as appreciated by those skilled in the art. In engines of the four-stroke variety, engine 833 includes a lubricating system (not shown). The lubricating system includes an oil reservoir (not shown) that must be drained and refilled routinely. Hull 824 may be made of any suitable material including molded fiberglass, reinforced resin plastic, and/or a sheet of molding compound. It is also further contemplated, the present teachings could be utilized in other watercraft such as motorboats without departing from the spirit of the invention. Watercraft 820 can also have mounting aperture 850 (FIG. 14) located anywhere on watercraft 820, such as back platform 852.
The motorcycle 920 illustrated in FIG. 1F includes a chassis 922, a seat 924 coupled to chassis 922, a front wheel 926 coupled to chassis 922 by a front fork 928, and a rear wheel 930 coupled to chassis 922 by a swing arm assembly 932. Steering member 942 can be used to steer wheel 926 or 930. A tail section 934 forms the rear portion of motorcycle 920 underneath seat 924 and above rear wheel 930. Motorcycle 920 can also have mounting aperture 950 (FIG. 15) located anywhere on motorcycle 920, to attach an accessory such as saddle bag 952. Engine 940 can be coupled to at least some of wheels 926 and 930 of motorcycle 920 for propelling motorcycle 920.
With reference to FIG. 2, a side profile of an expansion retainer in an open position in an embodiment of the present teachings is shown. Expansion retainer 300 has a proximal end 302 and a distal end 304, where distal end 304 is capable of being received by mounting aperture 406 (FIG. 5) or 226 (FIG. 9). Expansion retainer 300 can have a handle member 306, a shaft 308 pivotally coupled to handle member 306 at proximal end 302 allowing handle member 306 to be pivotally rotated between an open position (shown in FIG. 2) and closed position (shown in FIG. 3) to move shaft 308 in an axial direction, a grommet 310 located on shaft 308 at distal end 304, a fastener 312 coupled to shaft 308 at distal end 304, a spacer member 314 located proximal of grommet 310, and a bracket member 316 coupled at proximal end 302 of shaft 308 between handle member 306 and spacer member 314. Pin member 318 pivotally couples shaft 308 to handle member 306. Fastener 312 is illustrated as a nut and washer assembly, however, fastener 312 could be most any type of fastener such as a “C” shaped keyway, a large diameter nut, a cotter pin assembly, or a flange at the distal end of shaft 308 without departing from the spirit of the present teachings.
With reference to FIG. 3, a side profile of an expansion retainer in a closed position in an embodiment of the present teachings is shown. Handle member 306 can pivot about pin member 318 (FIG. 4) so when handle member 306 is moved from an open position to a closed position handle member 306 acts as a cam to move shaft 308 in an upward axial direction. This axial movement causes grommet 310 to be compressed between spacer 314 and fastener 312 thus expanding outward giving the grommet a greater diameter than it originally had as shown in FIG. 2. As illustrated, fastener 312 is a nut and washer assembly. When handle 306 is placed in the closed position, the washer on the bottom side prevents grommet 310 from expanding axially and causes it to expand radially outward. The nut and bolt assembly also provides some variability and adjustability for expansion retainer 300. For example, the operator could tighten the nut down to compress the rubber more or less, thus controlling the grommet's diameter during expansion.
Grommet 306 can be a rubber material, however, grommet 306 could be any material with similar elastic properties and strength to rubber without departing from the spirit of the present teachings. Further, while grommet 306 is illustrated as cylindrical, grommet 306 can have any shape. Spacer 314 can be made out of most any material including hard plastics, nylon, or metal and can be stiffer than grommet 310 as long as spacer 314 won't compress when handle member 306 is moved from the open to closed position. Spacer 314 can be used to insure grommet 310 is located within mounting aperture 406 (FIG. 6) or 226 (FIG. 9), which is discussed in more detail below. Bracket member 316 can be used to attach expansion retainer 300 to an accessory or any other item to be retained to mounting aperture (FIG. 6) or 226 (FIG. 9) and is discussed in more detail below. An accessory can be an item desirable to be attached to a vehicle such as a weed sprayer, cargo, or even vehicle accessories such as a radio. Bracket member 316 is illustrated as an “L” bracket, but could be most any type of bracket or have most any shape to attach accessories to expansion retainer 300. Alternatively, an oversized washer 520 (FIG. 10) could be substituted for bracket member 316 where oversized washer 520 would rest upon the top of an accessory and hold the accessory to accessory platform 222 when handle member 306 was rotated to the closed position.
With reference to FIG. 5, a side profile of an expansion retainer in an open position in an embodiment of the present teachings is shown. In some embodiments, expansion retainer 500 can have two grommets 502 and 504 located between spacer 506. When handle member 508 is moved from an open to a closed position, a shaft (not shown) is moved upward in an axial direction. As the shaft is moved upward, grommet 504 is compressed between spacer 506 and fastener 510 and grommet 502 is compressed between bracket 512 and spacer 506.
With reference to FIG. 6, an elevated profile of an accessory platform in an embodiment of the present teachings is shown. Accessory platform 400 can have a top surface 402 and a bottom surface 408 coupled to chassis 404. Accessory platform 400 can be a glass filled plastic, however, accessory platform 400 can be made out of most any material, such as plastic, metal, or wood without departing from the spirit of the present teachings. As illustrated, accessory platform 400 can have at least one mounting aperture 406. In some embodiments, mounting aperture 406 extends from top surface 402 to bottom surface 408. In other embodiments, mounting aperture 406 extends from top surface 402 within accessory platform 400. It is helpful if mounting aperture 406 extends from top surface 402 to bottom surface 408 to prevent debris from collecting within. Debris would prevent expansion retainer 300 from being properly located within mounting aperture 406 to ensure adequate clamping force. By having mounting aperture 406 extending from top surface 402 to bottom surface 408 aperture 406 is generally self cleaning and therefore does not require any preparation before placing retainer 300 within aperture 406.
Mounting aperture 406 can have a slightly larger diameter than grommet 310 in order to accept grommet 310 into mounting aperture 406 during insertion of retainer 300 or retainer 500. Mounting aperture 406 can have a chamfer 410 on top surface 402, which allows the operator to center expansion retainer 300 quickly, and to assist the operator in alignment when inserting retainer 300 into mounting aperture 406, as is discussed in more detail below. Mounting aperture 406 can have a draft 412 within to assist grommet 310 sliding into mounting aperture 406, however, it is contemplated mounting aperture 406 could be without a draft as long as mounting aperture 406 can accept grommet 310 within. However, a draft can assist in the insertion of grommet 310 into mounting aperture 406. Additionally, grommet 310 can have a diameter less than the diameter of mounting aperture 406 so grommet 310 can be received within mounting aperture 406.
In some embodiments, the axial length of mounting aperture 406 can be slightly shorter than the axial length from bracket member 316 to grommet 310. In this embodiment, a portion of or all of grommet 310 can protrude beyond bottom surface 408 of accessory platform 400. When handle member 306 is moved from the open to closed position, grommet 310 compresses and expands radially outward, increasing its diameter and by doing so becomes larger than the diameter of mounting aperture 406 as shown in FIG. 7. When compressed grommet 310 expands larger than the diameter of mounting aperture 406 or 226 and, therefore, retainer 300 cannot be pulled back through mounting aperture 406 or 226. Further when compressed below bottom surface 408, expansion retainer 300 is pulled toward top surface 402 as well as any accessory coupled to retainer 300. Grommet 310 can expand either within mounting aperture 406 or 226 or below bottom surface 408 thus making it very difficult to pull retainer 300 through or out of mounting aperture 406 or 226. In other embodiments, where grommet 310 expands within mounting aperture 406 or 226, expansion retainer 300 or 500 is held within mounting aperture 406 or 226 by a friction force, which makes it difficult to pull retainer 300 or 500 from mounting aperture 406 or 226.
With reference to FIG. 5 once again, when handle member 508 is moved from the open position to closed position grommet 504 is compressed between spacer 506 and fastener 510 and grommet 502 is compressed between bracket 512 and spacer 506. When grommet 504 expands this prevents retainer 500 from being removed from mounting aperture 406 or 226. Grommet 502 can expand above top surface 402 or within mounting aperture 406 or 226, thus not only adding friction resistance against retainer 500 being removed from mounting aperture 406 or 226, but grommet 502 also can act a sound dampener to prevent noise when the accessory is bouncing against accessory platform 400 during travel.
Expansion retainer 300 or 500 provides advantages and benefits over other mounting/clamping methods. Retainer 300 or 500 distributes the clamp force over a larger area than a bolt or pin. This allows for an increased load carrying capacity. It also decreases the possibility of casing damage to aperture surface or structure. Expansion retainer 300 or 500 is also significantly easier to use compared to other accessory mounting systems. The clamping operation is above the mounting surface and does not require tools. To fasten an accessory or object using expansion retainer 300 or 500 does not require removal of an accessory platform or working below the top surface of the platform. This decreases the time necessary to secure the object to the vehicle.
With reference to FIG. 8, a flow chart for the operation of an expansion retainer in an embodiment of the present teachings is shown. At state 600, expansion retainer 300 is coupled to an accessory. Distal end 304 can be inserted into mounting aperture 406 of accessory platform 400 at state 602. Handle member 306 can be rotated pivotally from an open position to a closed position, thus moving shaft 308 in an axial direction to compress grommet 310 and retaining expansion retainer 300 within mounting aperture 406 at state 604.
With reference to FIG. 10, a side profile of an expansion retainer in an open position for insertion into an accessory platform in an embodiment of the present teachings is shown. Expansion retainer 500 can also be coupled to an accessory with bracket 512, however, expansion retainer 300 or 500 can also be coupled to an accessory with an oversized washer 520. An accessory could be placed within box 222 generally near two adjacent sides, such as sides 230, 232, and 234. When the accessory was in position near two or more adjacent sides, retainer 500 could be placed within mounting aperture 226. As mounting aperture 226 slides into mounting aperture 226, bottom surface 522 of washer 520 could come in contact with the top surface of an accessory. Handle 508 could then be rotated to a closed position thus expanding grommets 502 and 504 to retainer expansion retainer 500 within mounting aperture 226 and thus providing a downward holding force to the accessory. As can be seen from FIG. 9, box 222 can have a plurality of mounting apertures 226 allowing for the use of several retainers 500 to provide additional clamping forces. It is contemplated the accessory could come with its own coupling connection which would line up with apertures 406 or 226 and a retainer 300 or 500 could be used without a bracket 512 or washer 520.
With reference to FIG. 11, a box divider with integral brackets in am embodiment of the present teachings is shown. Divider 700 allows the vehicle operator to separate box 222 into several compartments for holding accessories. Divider 700 could be placed in box 222 where mounting apertures 226 would receive retainers 702 and 704 on opposite sides of box 222, for example sides 230 and 232. Retainers 702 and 704 could then be rotated to a closed position to retainer divider 700 to box 222. Divider 700 allows a vehicle operator to easily separate box 222 into multiple compartments, which can be helpful to the operator, for example, if the operator were hauling two materials he did not wish to get mixed.
With reference to FIG. 12, a front profile of a quick removal mirror in some embodiments of the present teachings is shown. Snowmobile 30 can have one or more mounting apertures 60 to attach an accessory such as a luggage rack 62. Additionally, luggage rack 62 can have mounting apertures 64 to retain an accessory such as a backrest 66. In operation, the operator would place luggage rack 62 over mounting apertures lining up expansion anchors 68 with mounting apertures 60. Expansion anchors 68 are then pivoted to a closed position thus expanding the grommet to hold luggage rack 62. If the operator desires, they can then align expansion retainers 70 with mounting apertures 64 and place retainers 70 within apertures 64. Once again, retainers 70 are pivoted to a closed position expanding the grommet to retain backrest 66 to luggage rack 62.
With reference to FIG. 13, a front profile of a quick removal mirror in some embodiments of the present teachings is shown. Similar to above, expansion retainer 80 can be used to attach an accessory such as a mirror 82 to snowmobile 30. In operation, the operator could raise hood 84 and place retainer 80 through mounting aperture 86. Mirror 82 could then be screwed upon shaft 88 until mirror 82 is snug against hood 84. The operator could then pivot retainer 80 from an open position to a closed position thus retaining mirror 82 firmly against hood 84.
