wherein the second connecting leg has a drainage channel formation portion and the first connecting leg has a drainage channel accommodation portion,
wherein the drainage channel formation portion of the second connecting leg is configured to be accommodated in a drainage channel accommodation portion of a connecting leg of another base frame module, and
wherein the drainage channel accommodation portion of the first connecting leg is configured to accommodate a drainage channel formation portion of a connecting leg of a further, different base frame module.
13 . A method for connecting a first base frame module to a second base frame module of a window frame system, comprising the steps of:
mounting the first base frame module on a roof structure, wherein a frame leg of the first base frame module is designed as a first connecting leg and the first connecting leg has a drainage channel accommodation portion;
providing the second base frame module, wherein a frame leg of the second base frame module is designed as a second connecting leg and the second connecting leg has a drainage channel formation portion;
mounting the second base frame module on the roof structure next to the first base frame module by connecting the first connecting leg to the second connecting leg, wherein in the connected state of the first base frame module and the second base frame module, the drainage channel formation portion extends from the second connecting leg toward the first connecting leg and its distal end region is accommodated by the drainage channel accommodation portion, so that a drainage channel is formed along the connected connecting legs, which prevents water from penetrating from above the drainage channel into a space between the connecting legs below the drainage channel; and
arranging a window sash at the mounted first base frame module and a window sash at the mounted second base frame module.
