Abstract

A framework for supporting the glass panels of a skylight is formed of spacedrafters inter-connected by cross bars. The rafters have upstanding side flanges provided with pairs of transverse slots. The ends of the cross bars have pairs of outwardly extending headed members adapted to be engaged in the slots to locate the cross bars. The rafters have a ledge below each side flange upon which the bottom of a cross bar can rest. The cross bars are locked in place on the rafters by extending a pin from the cross bar to engage in a recess on the underside of the side flange. The recesses and ledges in the rafters form parts of gutters. A channel-like gutter is also provided on the sides of the cross bars so that condensation from the cross bars will flow into the channel gutters and then to the gutters in the rafters where it can flow to a collection point.
