Abstract
A shelf apparatus for use with a ladder or scaffold structure is provided. The shelf apparatus includes a substantially planar shelf structure having a plurality of holes positioned on a first side, wherein at least one of the plurality of holes is formed about a first axis positioned substantially perpendicular to the shelf structure. A cross-member engagement support is positioned on a second side of the shelf structure, the second side of the shelf structure opposite the first side, wherein the cross-member engagement support is formed about a second axis running from a first edge to a second edge of the shelf structure, and wherein the second axis intersects the first axis. A ladder-attachment structure is affixed to the shelf structure.

A shelf apparatus comprising:
- a substantially planar shelf structure having a plurality of holes positioned on a first side, wherein at least one of the plurality of holes is formed about a first axis positioned substantially perpendicular to the shelf structure;
- a cross-member engagement support positioned on a second side of the shelf structure, the second side of the shelf structure opposite the first side, wherein the cross-member engagement support formed about a second axis running from a first edge to a second edge of the shelf structure, and wherein the second axis intersects the first axis;
- and
- an attachment structure affixed to the shelf structure for removably mounting said shelf structure on at least one of a ladder and a scaffold system.
A shelf apparatus comprising:
- a first ladder-attachment structure affixed to a shelf structure on a second side, and a second ladder-attachment structure positioned on a first side, said second ladder-attachment being positioned opposite said second side;
- wherein said first and second ladder-attachment structures are useable to retain said apparatus on a ladder;
- wherein said first ladder-attachment structure is configured to engage with a rung of said ladder, where said rung fits said first ladder-attachment structure;
- wherein said second ladder-attachment structure is positionable against legs of said ladder to hold said apparatus in place on said ladder, and
- wherein said apparatus is secured stably to support placement of tools and other items on said shelf structure, and within said holes.
A method for removably mounting a shelf structure on a east one of a ladder and a scaffold system, the method comprising:
- providing a shelf structure configured with a first ladder-attachment structure affixed to said shelf structure on a second side, and a second ladder-attachment structure positioned on a first side, said second ladder-attachment being positioned opposite said second side;
- wherein said first and second ladder-attachment structures are useable to retain said apparatus on a ladder;
- wherein said first ladder-attachment structure is configured to engage with a rung of said ladder, where said rung fits said first ladder-attachment structure;
- wherein said second ladder-attachment structure is positionable against legs of said ladder to hold said apparatus in place on said ladder, and
- wherein said shelf structure is secured stably to support placement of tools and other items on said shelf structure, and within said holes.
