Abstract
Abstract A portable collapsible shelter for use at sporting events and the like includes a rectangular flexible enclosure having a viewing window in one wall thereof. The enclosure is supported by a frame which includes a central, hollow, telescoping support pole. The telescoping support pole permits the height of the shelter to be adjusted. When not in use, the entire shelter may be transported and stored within the telescoping support pole. In a second embodiment of the invention, the frame includes a vertical support pole and a plurality of ribs hinged for movement from a collapsed position alongside the pole to an extended position nearly perpendicular to the pole. The enclosure is left in place over the frame when the ribs are collapsed, and folded into a compact storage packet which is secured with a fastening band.
