  • Patent number: 5601105
    Abstract: A self-erecting tent having three closed loop frame members that crisscross themselves along their respective left and right mid-points. The first closed loop frame member is threaded through the front sleeve and the rear arch sleeve of the tent body. The second closed loop frame member is threaded through the upper front arch sleeve and the rear floor sleeve of the tent body. The third closed loop frame member is threaded through the lower front arch sleeve and the rear floor sleeve. This produces a tent body having a lower front panel, an upper front panel, a central panel and a rear panel. A front door opening is formed in the lower front panel. The entire structure can be folded, twisted and bound into a flat circular package for transportation and storage. When released, the collapsed structure instantaneously springs back into a complete and fully erected tent.
