Abstract

A tent comprises end walls of trapezoidal shape and pole structures which support the tent via the tops of its end walls. A sleeve is provided along the top of each end wall and a ridge pole is disposed within the sleeve, the sleeves and the ridge poles being of essentially identical lengths. The sleeves are provided with openings facing downwardly and longitudinally inwardly, and end-to-end separably connected pole sections support the ends of the ridge poles. Supporting each end of each ridge pole are exactly three end-to-end separably connected pole sections. The lengths of all ridge poles and pole sections are essentially identical and equal to the width across an individual's shoulders whereby the tent can be collapsed into a compact package suitable for backpacking The ridge poles are bowed so as to be concave in an upward and outward sense and right angle fittings provide the connections between the ends of the ridge poles and the end-to-end connected pole sections which support the ends of the ridge poles.
