Entfaltbare Dachkonstruktion

The invention relates to a roof construction (10) with several upright discharging arches (11) supporting an extended roofing (15), whose two ends are spaced at a fixed distance in a supporting state. Each discharging arch (11) comprises partial elements (12; 12a, 12b) interconnected by joints (13). Each joint (13) has a catch to limit the unfolding of the neighboring partial element (12a, 12b) to its approximately stretched position. When the discharging arch (11) is in a supporting position, all its joints (13) are bridged by sub-tensed pull connectors (16) which engage on both sides of the bridged joint (13) on a partial element (12a, 12b). In addition, a spacer (19) is provided in the area of each joint (13) acting between the discharging arch (11) and the corresponding pull connector (16), which swings the pull connector (11) inwards along the line of connection defined by both points of attack (18a, 18b). Roof constructions with relatively long discharging arches can thus be securely supported while at the same time enabling fast and easy folding and unfolding of the roof construction.
