US Patent 7261116 Tent with extendable windows

A tent (10) with extendable windows (14) having a main structure (12) including a plurality of walls (16, 18, 20) which are oriented at a first angle (60) with respect to a vertical reference. The tent (10) also includes at least one window (14) which is extendable to a second angle (62) with respect to a vertical reference, where the second angle (62) is a more negative angle than the first angle (60) thus producing windows (14) which are horizontally extendable further than the tent walls (16, 18, 20).
