A tray for supporting tools, paint cans, painting supplies and the like is pivotally held in a selected position by an elongated frame removably attached to a ladder rail. The ladder tray includes a folding shelf, a shelf support, a rail embracing frame, a hinge means connecting the shelf and support to the frame, and hooks for engaging the rungs of the ladder. A variety of apertures, depressions and/or raised areas exist on the tray in various sizes and shapes and are adapted for holding tools or for temporary placement of cans, bottles, jugs, tools and the like on shelf. When mounted, the ladder tray extends out from one side of the ladder and does not prevent a user from climbing up or down the ladder. It may be folded down alongside the rail of the ladder to a space saving transport or storage position or may be folded and removed from the ladder to store.

1. A pivotally adjustable ladder tray in combination with a ladder having at least two rungs, a first side rail and a second side rail, the ladder tray consisting of: an elongated frame including an elongated top section covering a top edge of said first side rail, an elongated outside section cover
1. A pivotally adjustable ladder tray in combination with a ladder having at least two rungs, a first side rail and a second side rail, the ladder tray consisting of: an elongated frame including an elongated top section covering a top edge of said first side rail, an elongated outside section covering an external side of said first side rail and extending orthogonally from said elongated top section, and an elongated inside section covering an internal side of said first side rail and extending orthogonally from said elongated top section;said elongated frame extending over a major length of said first side rail at least a distance between an adjacent pair of rungs of said at least two rungs;two hooks protruding from said elongated inside section and separated a distance equal to the distance of the adjacent pair of rungs, each hook respectively defining a top horizontal member with a distal end member extending downwardly and vertically therefrom;each one of said hooks resting upon a top surface of the selected adjacent rungs of said ladder respectively with the distal end members respectively partially encircling said adjacent rungs to removably hold said elongated frame to said first rail and said adjacent rungs;said hooks and said elongated inside section are coplanar and lie within a first plane, the first plane aligns parallel to a second plane formed by the elongated outside section and between the two planes defines a channel with a width, wherein the width of the channel is wider than a width of the first side rail so that the channel of the elongated frame can receive the first side rail;a foldable shelf extending from said elongated frame via a first hinge that directly connects the foldable shelf and the elongated outside section, the first hinge allows the foldable shelf to pivot between a first shelf position and a second shelf position, said shelf including a rim extending around all four sides of a peripheral edge of said shelf, said shelf including a pair of spaced apart shelf lugs of the first hinge that extend from an edge of the shelf adjacent to said elongated frame, said elongated frame including a frame lug of the first hinge that correspondingly engages said pair of spaced apart shelf lugs via a means for pivotably connecting said shelf lugs to said frame lug;an elongated pivotable shelf support having a bottom end directly attached to a second hinge, the second hinge being directly attached to the elongated outside section and capable of pivoting the pivotable shelf support between a first support position and second support position, said shelf support including a top end edge that cooperatively engages and supports a bottom surface of said foldable shelf in the first support position and in the first shelf position, when the shelf support is positioned in the second support position it is substantially orthogonal to the first support position and is aligned substantially flat against the elongated outside surface while further allowing the foldable shelf to fold to the second shelf position which is substantially orthogonal to the first shelf position and substantially aligned flat against the shelf support;the elongated pivotable shelf support extends outwardly from the elongated outside section at an angle of 15 degrees with respect to a major length of the elongated outside section. 2. The ladder tray of claim 1, said foldable shelf including holding means selected from the group consisting of an aperture, a groove, a depression, a ridge, and a textured surface. 3. The ladder tray defined in claim 1 wherein said ladder tray is made from a material selected from the group consisting of structural foam material, aluminum, fiberglass, plastic and combinations thereof.
