Abstract : The patent covers tents of the frameless type which are formed of lightweight and substantially impervious material. The lower edges of the walls of such tents are sealed to the ground and the rest of the tent is supported above the ground by low air pressure. The invention provides an improved closure and access opening combination for a tent of this type. The closure is secured in the closed position in sealing relation to the access opening by the pressure of air which supports the tent. The closure is automatically maintained in the closed position by gravity.
