Fly screen for a turn-tilt windows and turn-tilt window provided with the fly screen

摘要

An insect screen 11 for a tilt & turn window 1 has an accordion-shaped netting 13 and two attached profiles 15 and 17. Profile 17 is detachably attached to the window pane 5. The tilt & turn window is provided with means to let the profiles automatically return from the unfolded to the folded position of the netting when profile 17 is detached from the window pane. These means are formed by two helical springs 23 which are each attached at one end to the partial profile 17a and at the other end to a cord 25 which is led by a diversion element to the partial profile 15a. When opening the window pane 5 the helical springs 23 are extended. When profile 17 is then detached from the window pane 5, the helical springs 23 contract and profile 17 is pulled towards profile 15.
