The present invention relates to a foldable ladder attachment adapted to be secured to the rungs of a ladder to provide a platform for paint cans, brushes or like appurtenances or tools. The device is characterized by a novel linkage assembly enabling the apparatus to be readily accommodated to be affixed at an acute or an obtuse angle to a straight or extension ladder or inside or outside the sections of a folding ladder, without necessitating the employment of extensible stretcher mechanisms or like cumbersome devices as embodied in scaffold or platform supports heretofore known.

A foldable platform attachment for a ladder comprising a rigid, generally rectangular carrier platform having front, rear and side edges, said platform including adjacent each of its side edges a foldable linkage arrangement adapted to assume a triangular configuration, each said linkage arrangement including a hook member fixed to said platform adjacent its front edge and adapted to be engaged over a ladder rung, a hanger arm pivotally depending from said hook member for movement about a first pivot axis parallel to the plane of said platform, said hanger arm being adapted to engage against adjacent ladder rungs and including a plurality of longitudinally spaced lock apertures, a lock bar having a free end and having a second end connected to said platform adjacent said rear edge for pivotal movement about a second axis parallel to said first axis between first and second limiting abutting positions against said platform, said bar extending beyond said rear edge of said platform in one said limiting position and beneath said platform in said other limiting position, and a stretcher leg having one end pivotally connected to said free end of said lock bar for movement about a third pivot axis parallel to said other pivot axes, said stretcher leg including at its other end a connector portion complemental to and adapted to engage a selected lock aperture of said hanger arm.
