Abstract:

An apparatus (10) for the attachment and storage of a collapsible structure (12) to a roof of a recreational vehicle is disclosed. The apparatus (10) includes a guide means (11) fastened to a container (35). Roller means (13) is fastened to the collapsible structure (12) to allow for slidably moving the collapsible structure on the guide means (11). To remove the collapsible structure (12) from the container (35) when in a stored position, the collapsible structure (12) is slid along the guide means (11) until the collapsible structure (12) is outside the container (35). The collapsible structure (12) is then allowed to rotate downward and the collapsible structure (12) is then unfolded. The roller means (13) is releaseably attached to the guide means (11) to provide a free-standing unit. In a first embodiment, the container (35) is constructed for an add-on attachment to the roof of a recreational vehicle.
