Abstract: A collapsible and portable, tent-like structure including a frame portion and a covering portion for the frame and including frontal and rear panels which are easily attachable to the frame portion when the same is erected. The structure allows a plurality of units to be joined in end-to-end relation. The frame structure is provided from a plurality of scissor sections having selected portions of each scissor section being joined to the next adjacent scissor section with the sections of one scissor section being positioned with respect to the next such section to bring other selected portions thereof into abutment with other selected portions of the next adjacent scissors section. This relationship allows both an over-center relation of adjacent scissors sections and also provides an abutment locking arrangement between adjacent scissor sections. The unit also provides cover tensioning means for the main covering of the framework and means for securing the unit to the ground or other supporting surface.
