ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an arrangement of a mobile accomodation which comprises (i) a central structure having a floor, a roof, front and rear end walls, and at least one longitudinal side wall that is movable out from the central structure; (ii) foldable floor and roof sections that are hinged to edges of the longitudinal side wall and edges of the central structure and that are adapted to be unfolded as the longitudinal side wall is moved out from the central structure, and (iii) front and rear side walls hinged to the side edges of the front and rear end walls of the central structure and adapted to be swung out perpendicular to the longitudinal side wall of the central structure.
Mobile accomodations of activities of this kind are previously known from Swedish patent 9403670-4. It has become apparent in practical use that the movement of the longitudinal side walls may involve hard stresses of exposed parts and hinges. This is the case particularly in windy weather conditions because the roof sections that are folded upwards during the movement of the longitudinal side walls can catch a great deal of wind.
OBJECT OF THE INVENTION
The object of the invention is to achieve an arrangement of a mobile accomodation in which the disadvantage mentioned above is eliminated.
This is achieved according to the invention in that in an expansion operation, the front and rear side walls are adapted to be initially swung out perpendicular to the longitudinal side wall and positioned by ground supports, and in that top and bottom portions of inner sides of the front and rear side walls are provided with rails, and top and bottom portions of front and rear side edges of the longitudinal side wall are provided with respective guide members which are movably journalled on the rails. Due to the fact that the front and rear side walls can be swung out and secured against the ground initially, a strong stabilization is achieved of the longitudinal side wall during its movement outwards. This is obtained by both ends of said side wall being provided each with two guide members running along rails or similar members attached to the top and bottom portions of the two front and rear side walls. The movable, longitudinal side wall is positively controlled such that the side wall is never obliquely positioned. This is achieved by using a driving unit that moves the guide members synchronously outwards and back.
According to a preferred embodiment of the invention each guide means comprises a driven pinion that runs meshing with a rack rail surface of each rail.
