Description

SUPPORT ACCESSORY FOR SUPPORTING PORTABLE ITEM ON SHAFT OF JOCKEY WHEEL TECHNICAL FIELD

[0001] The presently disclosed subject matter generally relates to the field of support accessories for use with mobile recreational vehicles such as motorhomes, campervans, trailers, and the like. Particularly, the present subject matter relates to a support accessory for supporting a portable item on a shaft of a jockey wheel that is typically used with a mobile recreational vehicle.

BACKGROUND

[0002] Many types of recreational conveyances such as motorhomes, campervans, and other vehicles such as boats are typically hauled using a trailer. These trailers come in various sizes, shapes and/or configurations that may in turn employ a jockey wheel for facilitating movement of the recreational vehicle during transport, or alternatively, for parking the recreational vehicle at a designated location, for example, by disconnecting a yoke of a frame that is associated with the trailer from a hitch of the hauler vehicle. As the jockey wheel is typically attached to a yoke of the trailer, the jockey wheel also facilitates a user to operably cause movement in the height of the trailer relative to a ground surface.

[0003] Accompanying the use of a recreational vehicle, campers may also wish to cook food using portable devices such as, but not limited to, a barbequing (BBQ) set, a cookware appliance such as a portable gas stove, and the like. Australian Publication AU 2017101427 (hereinafter referred to as "the '427 reference") discloses a camping accessory for stowing devices such as the portable BBQ set thereon. However, the camping accessory of the '427 reference is designed to directly clamp onto the yoke of the trailer and therefore, entails the use of a clamp alongside a bulky inverted U-shaped bracket for mounting the clamp onto the yoke of the trailer. Further, the camping accessory of the '427 reference is also not convenient to manufacture and poses several challenges in the respect that it requires one or more welded components such as, for example, the arm which is rendered in a tiered or Z-shaped configuration using both tubes and pipes that have square and circular cross-sections respectively, thereby increasing not only a number and type of components required but also a level of complexity in the design and manufacture of the camping accessory. Moreover, although the '427 references mentions that one of the types of vehicle attachments in the disclosed camping accessory may include a jockey wheel attachment, the '427 reference does not disclose any features pertaining to a construction of the attachment to that effect i.e., attaching the camping accessory to thejockey wheel. Even if the '427 reference were to disclose at least a type, nature, or even the manner of producing the attachment for doing so i.e., attaching the camping accessory to the jockey wheel, it would have remained silent, or been at least unclear, on the issue of the inverted U-shaped bracket becoming redundant as the jockey wheel itself would be used alongside such a U-shaped bracket for mounting onto the yoke of the trailer.

[0004] In light of the foregoing shortcomings, there is a need for an improved accessory for facilitating a user in supporting a portable item on a shaft of a jockey wheel. Further, there is also a need for an accessory that is easy to manufacture while obviating the need for, or use of, any complex manufacturing process such as welding and the like for producing the accessory. Furthermore, there is also a need for an accessory that directly mounts to a shaft of a jockey wheel instead of mounting to the yoke of the trailer as the latter process could be regarded as a laborious task by some users of recreational vehicles who wish to cook or place objects on a stable platform.

SUMMARY

[0005] To overcome the above-mentioned limitations, the present disclosure provides a support accessory for facilitating a user in supporting a portable item on a shaft of a jockey wheel.

[0006] The present disclosure provides a support accessory that directly mounts onto a shaft of a jockey wheel instead of directly mounting onto a yoke of the trailer. The use of the shaft from the jockey wheel may provide the concomitant use and advantage of at least some length of the shaft resulting in the support accessory being mounted at a greater height as opposed to mounting it directly onto the yoke of the trailer, and optionally, or additionally, requiring the use of some additional, or alternative, structure to provide the desired height that is required for the user not only in facilitating the mounting of the support accessory but also in facilitating an ease in the subsequent use of a portable item placed on the support accessory.
