发明名称 Tray for holllow-rung ladders
摘要 This invention is a tray that attaches to the side of hollow-rung ladders. The tray is sized large enough to accommodate an industry standard paint-roller-pan and hold it in a convenient position for the user either at the left side or at the right side of the ladder. The tray mounts to the ladder via a shaft that passes thru one hollow-rung. Secure attachment to various width ladders is accomplished via a safety-clip inserted into one of the series of thru-holes in the free end of the shaft that extends thru the hollow-rung. Adjustment of the tray to horizontal is accomplished via a movable L-shaped support that penetrates into a second hollow-rung. This invention contains fewer and simpler parts in comparison to prior inventions.
