Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
206 words
An expandible plug for use in securing a tent frame to the ground comprising: a lower plug means consisting of two symmetrical semi-circular portions, the inside surfaces of which are screw-threaded, and the outer diameter of said lower plug means being reduced towards the lowermost part and terminating in a point, the inner diameter of said lower plug means tapering inwardly to the point where the outer diameter diminishes, said lower plug means having a fixed ring circumferentially affixed to the upper portion of said plug means and an expandible ring circumferentially affixed to the lower portion of said plug means; a screw means consisting of a uniform cylindrical screw complementary to said screw-threading of said lower plug means; a handle means adapted to screw said screw means into said lower plug means whereby the lower portion of said lower plug means expands when said screw means is inserted into said lower plug means; means adapted to secure the frame of the tent to said expandible plug comprising a base plate with a hole therethrough through which the screw means is inserted into said lower plug means, and three short hollow tubes affixed to said base plate adapted to receive respective portions of the tent frame.
Claim 2
Dependent Claim
206 words
An expandible plug for use in securing a tent frame to the ground comprising: a lower plug means consisting of two symmetrical semi-circular portions, the inside surfaces of which are screw-threaded, and the outer diameter of said lower plug means being reduced towards the lowermost part and terminating in a point, the inner diameter of said lower plug means tapering inwardly to the point where the outer diameter diminishes, said lower plug means having a fixed ring circumferentially affixed to the upper portion of said plug means and an expandible ring circumferentially affixed to the lower portion of said plug means; a screw means consisting of a uniform cylindrical screw complementary to said screw-threading of said lower plug means; a handle means adapted to screw said screw means into said lower plug means whereby the lower portion of said lower plug means expands when said screw means is inserted into said lower plug means; means adapted to secure the frame of the tent to said expandible plug comprising a base plate with a hole therethrough through which the screw means is inserted into said lower plug means, and three short hollow tubes affixed to said base plate adapted to receive respective portions of the tent frame.
Claim 3
Dependent Claim
185 words
An expandible plug for use in securing a tent frame to the ground comprising: a lower plug means consisting of two symmetrical semi-circular portions, the inside surfaces of which are screw-threaded, and the outer diameter of said lower plug means being reduced towards the lower most part and terminating in a point, the inner diameter of said lower plug means tapering inwardly to the point where the outer diameter diminishes, said lower plug means having a fixed ring circumferentially affixed to the upper portion of said plug means and an expandible ring circumferentially affixed to the lower portion of said plug means; a screw means consisting of a uniform cylindrical screw complementary to said screw-threading of said lower plug means; a handle means adapted to screw said screw means into said lower plug means whereby the lower portion of said lower plug means expands when said screw means is inserted into said lower plug means, said handle means being an inverted t-shaped sleeve affixed to said screw means, said sleeve adapted to receive said frame of the tent thereby securing said plug to said frame.
Claim 4
Dependent Claim
185 words
An expandible plug for use in securing a tent frame to the ground comprising: a lower plug means consisting of two symmetrical semi-circular portions, the inside surfaces of which are screw-threaded, and the outer diameter of said lower plug means being reduced towards the lower most part and terminating in a point, the inner diameter of said lower plug means tapering inwardly to the point where the outer diameter diminishes, said lower plug means having a fixed ring circumferentially affixed to the upper portion of said plug means and an expandible ring circumferentially affixed to the lower portion of said plug means; a screw means consisting of a uniform cylindrical screw complementary to said screw-threading of said lower plug means; a handle means adapted to screw said screw means into said lower plug means whereby the lower portion of said lower plug means expands when said screw means is inserted into said lower plug means, said handle means being an inverted t-shaped sleeve affixed to said screw means, said sleeve adapted to receive said frame of the tent thereby securing said plug to said frame.
Claim 5
Dependent Claim
186 words
An expandible plug for use in securing a tent frame to the ground comprising: a lower plug means consisting of two symmetrical semi-circular portions, the inside surfaces of which are screw-threaded, and the outer diameter of said lower plug means being reduced towards the lower most part and terminating in a point, the inner diameter of said lower plug means tapering inwardly to the point where the outer diameter diminishes, said lower plug means having a fixed ring circumferentially affixed to the upper portion of said plug means and an expandible ring circumferentially affixed to the lower portion of said plug means; a screw means consisting of a uniform cylindrical screw complementary to said screw-threading of said lower plug means; a handle means adapted to screw said screw means into said lower plug means whereby the lower portion of said lower plug means expands when said screw means is inserted into said lower plug means, said handle means being a sleeve affixed at right angles to said screw means, said sleeve adapted to receive said frame of the tent thereby securing said plug to said frame.
Claim 6
Dependent Claim
186 words
An expandible plug for use in securing a tent frame to the ground comprising: a lower plug means consisting of two symmetrical semi-circular portions, the inside surfaces of which are screw-threaded, and the outer diameter of said lower plug means being reduced towards the lower most part and terminating in a point, the inner diameter of said lower plug means tapering inwardly to the point where the outer diameter diminishes, said lower plug means having a fixed ring circumferentially affixed to the upper portion of said plug means and an expandible ring circumferentially affixed to the lower portion of said plug means; a screw means consisting of a uniform cylindrical screw complementary to said screw-threading of said lower plug means; a handle means adapted to screw said screw means into said lower plug means whereby the lower portion of said lower plug means expands when said screw means is inserted into said lower plug means, said handle means being a sleeve affixed at right angles to said screw means, said sleeve adapted to receive said frame of the tent thereby securing said plug to said frame.
