Abstract
Abstract A portable, free-standing shelter for hunters and the like which is of generally frusto-conical configuration and has a base and upwardly inclined side panels terminating in an open top. The sidewalls are defined by a plurality of panels of generally trapezoidal configuration, having top and bottom edges connected by upwardly convergent opposite sides. Hinge means interconnect adjacent sides of the panels in articulated pivoting relation so that the side panels can be folded back over each other. The connected side panels may be arranged into various configurations. The top of the shelter can be closed with a suitable cover which is supported by a number of flexible rods or poles which are mounted diagonally across the top opening and have sufficient length to be bowed in an upward direction to suitably support the covering in a curved configuration. The side panels of the shelter also can be held in an extended stretched condition by a pair of flexible rods which are diagonally mounted across the corners of the side panel to hold it rigid. The flexible support rods can be arranged in telescoping sections with the entire shelter easily folded and carried as a small compact package.
