Hence, designer has liberty to leverage the mounting of the lid member (304) to the connecting member (400). In other words, the lid member (304) can be mounted in any peripheral walls such that it can be opened one of upward, downward, sideways direction as per the requirement and structure of the two-wheeled vehicle (200). Also, as the lid member (304) is not mounted to any portion of the body frame (100), there is minimal chance of misalignment of the lid member (304). Further, it is always easy for the user to push the opened lid member (304) downward to lock the lid member (304) over the enclosure rather than pushing the lid member (304) from the sideways direction or pulling-up the lid member (304) from the downward direction.
[0047] In an alternate embodiment, the side covers (306a, 306b) are connected to the tail light assembly (502) at rear side of the side covers (306a, 306b) to form an access opening, and the lid cover (304) rotates in substantially upward direction in an open position from a closed position for uncovering the access opening to allow access to the fuel tank cap. The lid cover (304) can be connected to the body frame (100) and more particularly to rear of the side covers (306a, 306b).
[0048] During filling of fuel into the fuel tank (302), or at the time when fuel gun is bought to or taken away from the fuel tank (302) or the connecting member (400), some fuel may be spilled in the connecting member (400). The connecting member (400) provides a cavity around the opening of the fuel tank (302) which separates the side covers (306a), (306b) and the tail light assembly (502), thus the fuel is made to get in contact with the connecting member (400) only which can be made up of fuel resistant material. Thus, all other body cover parts, reflector of tail light, etc are saved from being in contact with the fuel.
[0049] In conventional systems, fuel accumulated in the cavity of the connecting member (400), can pass through the locking slot (410) and can get in contact with the body parts of the vehicle, particularly, the reflector of the tail light and damage it. However, present invention precludes such occurrence with the inclusion of the enclosure (900).
[0050] The enclosure (900) of suitable shape is mounted to the connecting member (400), more particularly, to the lower wall (412b), of the connecting member (400), from the rear side i.e. from the side of tail light assembly (502) such that the locking slot (410) is completely covered and any spilled fuel into the connecting member (400) flows to the enclosure (900) and then drain out away from the plastic parts of the vehicle through a drain pipe (910). The enclosure (900) is mounted to the connecting member (400) using enclosure mounting provisions (412e) of connecting member (400). In an embodiment the opening of the drain pipe (910) is provided at the lowermost position of the enclosure (900). In an embodiment, the enclosure (900) is mounted to the lower wall (412b) and the lower portion flange (402b) of the connecting member (400) such that the locking slot (410) is completely covered. On one side of the enclosure (900), a cable opening (920) is provided to enable the lock cable to reach to the locking assembly (870). The cable opening (920) of the enclosure (900) is provided with a sealing member (930) to avoid leakage of fuel from the enclosure (900). In an embodiment, the sealing member (930) is rubber grommet.
[0051] While few embodiments of the present invention have been described above, it is to be understood that the invention is not limited to the above embodiments and modifications may be appropriately made thereto within the spirit and scope of the invention.
[0052] While considerable emphasis has been placed herein on the particular features of this invention, it will be appreciated that various modifications can be made, and that many changes can be made in the preferred embodiments without departing from the principles of the invention. These and other modifications in the nature of the invention or the preferred embodiments will be apparent to those skilled in the art from the disclosure herein, whereby it is to be distinctly understood that the foregoing descriptive matter is to be interpreted merely as illustrative of the invention and not as a limitation.
