Abstract: A purlin connection assembly including a purlin, a frame segment and a spring. The purlin has a protrusion that is receivable in a first end of a slot of the frame segment. The purlin is slidable to a smaller second end of the frame segment. Locking engagement is achieved in a direction parallel to the frame segment by a pair of push buttons projecting from the frame segment that flank the purlin when in the second end, and in a direction perpendicular to the frame segment by constraining of a flared head of the protrusion in an interior of the frame segment when in the second end. The push buttons are part of a spring compressingly disposed in the interior of the frame segment, wherein the first button and the second button are biased to extend outwardly through button holes of the frame segment.

Abstract: A modular tent frame system includes a number of folding frame elements which permit the shelter to be rapidly deployed in extreme environmental conditions. Telescopically sliding legs permit the tent frame to be unfolded, and the tent fabric attached to the frame, which the frame is on the ground and the tent can then be raised by sliding the outer leg elements up the inner leg elements to thereby raise the tent to the desired height, even in high winds.

Abstract: A modular tent frame system includes a number of folding frame elements which permit the shelter to be rapidly deployed. The folding elements incorporate joints with self-resetting lock mechanisms. During set up they automatically lock the joints into place and once unlocked they reset to automatically lock the joints into place on the next setup.
