FIELD OF INVENTION
This invention relates to the field of painting aids, and more specifically to a device for mounting a paint roller tray to a ladder.
BACKGROUND OF THE INVENTION
Paint rollers offer an easy and efficient way to pain flat surfaces. The roller eliminates brush marks and provides a smoothly finished surface for even the relatively unskilled painter. Paint rollers are typically charged with paint using a roller tray. This shallow rectangular tray usually has a sloped bottom surface with some ridges formed in it to help distribute the paint evenly over the roller. Painting with a roller and roller tray can become more difficult if it becomes necessary for the painter to stand on a ladder while painting. This often occurs when painting ceilings or higher portions of walls. When the painter must stand on a ladder, the positioning of the roller tray can be problematical. What is desired is a way to secure the roller tray to a ladder or step ladder in such a way that it can be easily removed and attached to facilitate filling and cleaning of the tray. Various inventions have been developed to address this problem.
U.S. Pat. No. 3,822,846, issued to Jesionowski, discloses a combination platform roller pan and tray for a paint roller that has a pair of aligned bosses which extend outwardly from each side thereof, the bosses being releasably engageable with locking means which is releasably associated with the ladder, the locking means in one form comprising a locking hook engageable with the step or rung of the ladder and, in another form, comprising a locking cam engageable in the rung of the ladder.
U.S. Pat. No. 4,424,949, issued to Kimmett, et al. is directed to an adjustable paint tray support for use on a ladder having a bracket for attaching to one of the legs of the ladder is disclosed. The bracket contains a section for engaging one of the steps or rungs on the ladder. A support member for the paint tray is pivotally connected to the bracket. The support member has a raised portion at each end for engaging the paint tray. A clamp is positioned on the bracket to engage a portion of the support member to releasably secure the support member with respect to the bracket.

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.
