ELEVATED WORK PLATFORM VEHICLE ATTACHMENT
An elevated work platform vehicle attachment is disclosed that includes a base assembly having primary and secondary connection members to detachably connect to a motor vehicle when a worker requires an elevated work platform. The attachment further includes a working platform operatively connected to the base assembly by a roller assembly that allows for rectilinear movement of the working platform relative to the base assembly. When the working platform is in an extended position, the base assembly provides cantilever support thereto and the roller assembly includes a locking mechanism to prevent movement of the working platform, both of which allow a worker to be safely positioned on the extended working platform.
The present non-provisional patent application relates generally to vehicular attachments, and more particularly, to devices and systems for assisting operators in trimming trees, vegetation, and other flora adjacent to roadways.
BACKGROUNDFederal, state, and local government agencies are generally responsible for the construction, maintenance, and operation of roadways within their jurisdiction. One component of roadway maintenance involves pruning and trimming trees, shrubbery, and other flora that grow along roads, streets, and highways and create an unacceptable risk or safety hazard to the motoring public (e.g., those blocking sight distance). Currently, maintenance workers depend on specialized aerial devices (e.g., bucket trucks or vehicles with dedicated scaffolding units) to gain access to roadside trees that are otherwise inaccessible due to their height and distance from the roadway. The availability and cost of purchasing or renting specialized aerial devices is a significant disadvantage for federal, state, and local government agencies with large roadway maintenance operations. A need therefore exists for a low-cost elevated work platform vehicle attachment (i.e., easily connected to, and disconnected from, a vehicle) for roadway maintenance, particularly pruning and trimming roadside trees, shrubbery, and other flora.
SUMMARYAn elevated work platform vehicle attachment is disclosed that includes a base assembly that may be removably attached to a motor vehicle when a worker requires an elevated work platform. The attachment further includes a working platform operatively connected to the base assembly by a roller assembly that allows for rectilinear movement of the working platform relative to the base assembly. When the working platform is in an extended position, the base assembly provides cantilever support thereto and the roller assembly includes a locking mechanism to prevent movement of the working platform, both of which allow a worker to be safely positioned on the extended working platform.
Other aspects of the disclosed elevated work platform vehicle attachment will become apparent from the following description of a presently preferred exemplary embodiment, and the accompanying drawings.

Claims
1. An aerial work platform attachment comprising:
- a base assembly; and
- a working platform comprising: a working platform base; and a railing assembly which bounds the perimeter of the working platform;
- wherein the base assembly is designed to be detachably connected to a vehicle; and
- wherein the working platform is operatively connected to the base assembly for rectilinear movement between a first position where the working platform is in a nested position, superjacent to the base assembly and a second position where the working platform is extended from the base assembly; and
- wherein the base assembly provides cantilever support for the working platform when in the second position.
2. The aerial work platform attachment of claim 1, wherein the working platform is operatively connected to the base assembly by a C-shaped roller assembly.
3. The aerial work platform attachment of claim 2, wherein the C-shaped roller assembly contains a pair of end caps and a pair of locking mechanisms for preventing disconnection of the working platform and the base assembly.
4. The aerial work platform attachment of claim 3, wherein the base assembly includes a pair of primary connection members and a pair of secondary connection members for detachably connecting the base assembly to the vehicle.
5. The aerial work platform attachment of claim 4, wherein the railing assembly includes an access point and at least a pair of tool rests.
6. The aerial work platform attachment of claim 5, wherein the access point is a door hingedly connected to the railing assembly.
7. The aerial work platform attachment of claim 5, wherein the base assembly includes a pair of ladders.
8. The aerial work platform attachment of claim 7, wherein the base assembly includes a first ladder that aligns with the access point when the working platform is in the first position and a second ladder that aligns with the access point when the working platform is in the second position.
9. The aerial work platform attachment of claim 8, wherein the working platform further comprises a pair of handles.
10. The aerial work platform attachment of claim 9, wherein the base assembly includes a pair of lift brackets for loading or unloading the aerial work platform attachment onto a vehicle.
