ABSTRACT:
This invention discloses a novel collapsible tent which is designed to reduce the humidity therein and which utilizes novel ground-holding means to hold it securely to the ground when erected. The tent covering comprises separate inflatable sections which is suspended over a triangular tent-type configuration of tubular support pieces. The tent is secured to the ground by utilizing expandible plugs which comprise a tapering casing with an expandible ring on its lower section. The casing is inserted into the ground and a screw-type device is inserted therein. This causes the casing to expand and to apply radial pressure to the ground thus providing a secure connection to the ground. The tent also utilizes novel eave troughs which are designed to be able to be used as a carrying case for the tubular support pieces once disassembled.
