33 a permit length and or angular displacement modifications that enable the adjustable container to adapt to a wider range of slopes possessed by not only peaked structures formed by the intersection of two planes forming a ridge type peak but sloped single planar surfaces 68 as well both common types of roofing structures depicted in fig1 and 12 the properties attributed to the four adjustable rotary hinges 42 fig8 include a convenient lock unlock feature that enables the adjustment and immobilization of the desired angular displacement and given the additional length adjustment provided by rotary adjustable support legs 33 a a user is presented with a myriad of mounting configurations example configurations noncomprehensive are depicted in fig8 11 and 12 fig1 depicts a configuration where the container midpoint 60 is positioned at an average distance between container 2 and planar surface 68 that is significantly greater than that depicted in fig 12 and may be better suited for a standing user that wishes to minimize bending action in contrast fig1 depicts an average distance between container 2 and planar surface 68 that is significantly less that that depicted in fig1 and may be better suited for a user that is lying or sitting to promote easy access to the contents of container 2 the convenient lock unlock feature can be implemented in various configurations static push pull slide activated momentary push button release cable controlled wing nut bolt assembly and the like a generous supply of adjustable rotary hinges 42 type mechanisms that are suitable for.
