DETAILED DESCRIPTION OF THE INVENTION

[0019] Embodiments of the present invention solve the above noted problems by providing dollies for two-wheeled vehicles that eliminate all problems and risks of injury to employees/customers, or motorcycle damage. Embodiments of the present invention lay flat on the ground (lowered configuration) and are quickly assembled from a broken down configuration, are connected to the motorcycle without having to touch the motorcycle or having to push or exert physical strain, and once the motorcycle is securely stabilized, by, for example, strapping it to the flat-laying apparatus, the wheels of the apparatus are able to descend down to lift the wheel of the motorcycle up with an easy stroke of the hand (apparatus' lifted configuration). This makes it possible for a single person to safely and effectively move a motorcycle, for example, to pull it onto a tow truck, and eliminates any risk of the motorcycle being tipped over while being handled. In addition, embodiments of the present invention have a highly compact configuration when disassembled for transportation.

[0020] Embodiments of the present invention comprise dollies for two-wheeled vehicles, and more particularly, dollies for motorcycles that allow a single person to lift and move a motorcycle unassisted.

[0021] Referring now to the Figures, in one embodiment, dolly 10 comprises frame 12, which is preferably formed when front segment 14 and rear segment 16 are assembled. Frame 12 can be fabricated of diverse suitable materials, which include but are not limited to metals such as tubular or solid steel, stainless steel, aluminum, and the like, plastic, wood, combinations thereof and the like. Preferably, front segment 14 comprises one or more preferably foldable connecting member 18 and rear segment 16 comprises one or more preferably foldable connecting member 20. In one embodiment, each segment comprises two connecting members that can attach to a corresponding counterpart to form frame 12. In one embodiment, connecting members 18 are manufactured of tubular steel that is larger in diameter than connecting members 20, as depicted in FIG. 6. Then connecting members 20 are inserted into connecting members 18 to assemble frame 12. Preferably, a locking mechanism is provided. For example, in one embodiment, the connecting members comprise matching perforations through which lock pins 22 are disposed. See FIG. 7. In a different embodiment, the apparatus comprises an automatic locking mechanism, for example, cam spring locks and the like.

[0022] Preferably, front segment 14 and rear segment 16 each comprise at least one wheel 24. Referring to FIG. 10, in a preferred embodiment, each segment comprises two wheels 24 and a mechanism that allows the wheels to have a lowered configuration for assemblage of the dolly 10 around the wheel of a motorcycle or another two-wheeled vehicle, and a lifted configuration for moving the two-wheeled vehicle.

[0023] Preferably, the mechanism allows wheels 24 in each segment to switch between lowered and lifted configurations simultaneously for better stability of the two-wheeled vehicle during lifting. Referring to FIG. 10, for example, in one embodiment, front segment 14 and rear segment 16 house axle 26 that connects to rotating wheel hubs 28 as the ends of axle 26 protrude from axle bearings 30. Preferably, rotating wheel hubs 28 comprise socket 32 into which a leverage tool such as metal rod or a screw driver, can be inserted to help switching to the lifted configuration. See FIGS. 2 and 8. Preferably, rotating wheel hubs 28 comprise a mechanism to lock them in their different configurations. For example, pins 34 can be inserted through matching holes axle bearings 30. See FIG. 9. Alternatively, the apparatus comprises an automatic locking mechanism, for example, cam spring locks and the like.

[0024] In an alternative embodiment, each wheel comprises means to switch independently between lowered and lifted configurations including but not limited to hydraulic or mechanical means similar to the wide variety of car jacks available.

[0025] Preferably, strap 36 is disposed from back to front or vice versa to secure the vehicle's wheel and one or more straps 38 are used to further stabilize it. See FIG. 3. Preferably, frame 12 comprises means for strap 36 to be secured, for example, square lock pins 39. In a preferred embodiment, towing ring 40 is disposed in the front of front segment 14 so that dolly 10 can be pulled, for example, onto the platform of a tow truck. Preferably, axle bearings 30 comprise rings 42 for optional attachment of straps 38.

[0026] FIG. 11 shows an alternative embodiment 10 of the invention, comprising frame 12, front segment 14, rear segment 16, connecting members 18, connecting members 20 (preferably having diameter greater than that of connecting members 18), lock pins 22, wheels 24, strap attachment hoops 50, and tow rings 40. In this embodiment, the wheels are attached 54 directly to tabs 56. The dolly is moved to lifted configuration by attaching chains 58 (or other like connectors) between opposing tabs 52.

[0027] Embodiments of the present invention also contemplate methods of safely moving a two-wheeled vehicle. In one embodiment the method comprises assembling a frame of a dolly around a wheel of the vehicle in a lowered configuration, securing the wheel to the frame of the dolly, and switching the dolly to a lifted configuration. In a preferred embodiment, either the front or the back of the dolly is lifted first. Alternatively, both ends are lifted simultaneously. Note that while the invention is particularly useful for two-wheeled motorcycles, it can additionally be useful for three-wheeled vehicles, such as a three-wheeled motorcycle, a two-wheeled motorcycle with a sidecar, etc.

[0028] Note that in the specification and claims, about or approximately means within twenty percent (20%) of the numerical amount cited.

[0029] Although the invention has been described in detail with particular reference to these preferred embodiments, other embodiments can achieve the same results. Variations and modifications of the present invention will be obvious to those skilled in the art and it is intended to cover in the appended claims all such modifications and equivalents. The entire disclosures of all references, applications, patents, and publications cited above are hereby incorporated by reference.
