  • Patent number: 4586291
    Abstract: A shallow two inch deep double hung window which is sufficiently water and wind resistant to replace jalousies, which can be used in cabana walls and which fits screen porches, utilizing existing screening. Block and tackle sash balance counter balance the weight of individual panels and provide a lateral resilient action to maintain panels in position. A double action leaf spring stop for each panel selectively disengages the sash balances therefrom so that by moving a panel laterally it is removable. Window and panel frame members consist of aluminum extrusions which facilitate construction of custom windows made to selected sizes. Inside or outside flanges for securing the window to the wall structure are optionally provided.
