Patent attributes
An expandable tent structure with a side wall of mesh or fabric enclosing an internal volume of the tent. The tent has one or more openings in the roof and/or side walls of the tent, and a hatch pivotally attached to the tent. The hatch in one position covers an opening in the roof and/or side wall, and a mesh or fabric structure extends in an accordion-like manner between the hatch and edges of the opening. A plurality of ribs support the mesh or fabric, the ribs being pivotally attached to the tent supporting structure. When the hatch is in its open position, the internal volume of the tent is increased, with the mesh or fabric attached to the hatch and the edges of the opening providing a barrier over the opening against the environment.
