ABSTRACT:
A selectively removable support platform is designed to be attached to the rungs of a conventional ladder. The platform includes pivotally interconnected arms which may be aligned with the hollow metallic rungs of the ladder, and connector pins pivotally attached to the arms may then be projected through apertures in the arms so as to be positioned within the rung interiors. Safety straps may then be used to lock the connectors in position, and platform alignment is facilitated through the use of a telescoping adjustable arm construction. Short safety chains may optionally be provided for connecting the platform to a gutter spout or some other building structure, and the front of the platform is covered with a rubber or foamed plastic material so as to prevent both slippage and damage to the structure against which the platform is resting. Additionally, the foam or rubber material provides an electrically insulative effect between the ladder platform and metal siding.
