Roller seat, and carrier for a very-large-capacity tool and material holder also mountable atop a step ladder

摘要

A combination (i) roller seat and (ii) tool and material carrier is preferably used with a hollow body tool and material holder detachably mountable to the upper region of an open step ladder. The combination roller seat and carrier has a substantially planar base with a structure in the shape of a truncated frustum attached to and extending above the base, this structure occupying a same shape and volume as does a truncated frustaconical upper region of a open step ladder. Wheels to the base permit a person to sit upon the top of the structure while the base rolls upon the wheels, making thereby a roller seat. When the hollow body tool and material holder detachably mountable to the upper region of the open step ladder is alternatively mounted over the structure, the structure serves at least indirectly to hold any tools and materials that are also held by this hollow body holder.
