314 in the collapsed configuration as shown the secondary supports 202 and 204 may be rotated by means of secondary support hinges 126 to allow the secondary supports to lie between the upper portion of the frames and the main supports in their lowered position as shown the first and second secondary supports are rotated away from the first and second frame respectively such that the first secondary support 202 is angled beneath the second frame 115 and the second secondary support 204 is angled beneath the first frame 110 in other embodiments each secondary support could rotate towards the frame to which it is attached such that it fits substantially flat beneath the frame to which it is attached in other embodiments the secondary supports could be removable instead of hinged such that they may be stored flat against the main supports in the lowered position as shown compartments 146 148 remain attached to the frames 110 115 such that when the shelter is in its collapsed configuration the compartments sit flat above the top of the collapsed structure the handles 152 and 154 as shown remain attached to the compartments positioned between the compartments at the top center of the collapsed structure in some embodiments the handles and or compartments may be removable such that they may be stored separately from the rest of the structure in other embodiments the structure may not include handles or may not include compartments fig4 illustrates the mobile shelter 100.
