the following description is demonstrative in nature and is not intended to limit the scope of the invention or its application or uses . fig1 shows the front view . triangular shape bottom surface 1 is approximately 8 . 5 inches long in front and 6 . 5 inches long on each side . bottom surface is perforated and has 2 degrees draft for drainage towards the front . the corner edges of the bottom surface are curved . there are two side walls 2 and 3 , each approximately 5 inches long and 1 inch tall and has a curved edge . these sidewalls are at 90 degree angle in relation to the bottom surface . front wall 4 is approximately ½ inch tall and 6 . 5 inch wide and has a curved edge . this front wall is at approximately 65 degree angle in relation to the bottom surface . thickness of the walls and the bottom surface is variable depending upon the material used which can be either steel , plastic or any other material appropriate for this application . triangular shape is convenient , practical and provides increased usable surface without compromise to the space in shower bath . this shape also allows converting the available upper surfaces of the two walls into weight bearing surfaces . weight is carried on the walls and not on the mounting screws allowing for storage of heavier items , eliminating the risk of breaking the mount and dislodging the tray . fig2 shows the side view with perforations 5 for drainage . the corner edge between the two sidewalls is curved allowing for installation in the curved corners . there is approximately 2 degrees draft at the bottom surface , which allows the fluids and water to drain towards the front and not towards the corner . the corner is open allowing easy cleanup and backward drainage , if desired , while cleaning . each sidewall contains a hole for the screw . the hole is above the bottom surface to prevent undesirable drainage through the hole . the hole is designed so that the tray can be easily mounted , removed and placed back . the different shape holes decrease the risk of accidentally dislodging the tray . installation of the tray is simple . the screw holes can be covered with variety of options for aesthetic or any other reason . fig3 shows the installation of the tray . to install the tray is placed in the corner on top of the walls and screwed into the sidewall on each side . to remove , the tray is lifted up slided sideway and outward . front wall is angled and is shorter than the sidewalls . this wall prevents the objects from falling . the size and the angle of this wall also provides for a surface on the outer side suitable for text or advertisement display . shorter front wall allows convenience while reaching the objects or placing them . this wall does not extent all the way to the corner to allow for fluid drainage on each side . it is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory but are not restrictive of the invention . the accompanying drawings , which are incorporated in and constitute a part of this specification , illustrate preferred embodiments of the invention and , together with the description , serve to explain the principles of the invention . the invention in its broader aspects is not limited to the specific details shown and described , and departures may be made from such details without departing from the principles of the invention and without sacrificing its chief advantages .
a corner mounted tray , atop the upper surfaces of shower bath walls , is triangular in shape , comprises a perforated bottom surface , upstanding sidewalls and angled front wall and is releasably attached to a vertical wall by screws . the tray is supported on top of the walls in the corner .
