Shelf apparatus for use with a ladder and scaffold
First Claim
1. 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 is formed about a second axis running from a first edge to a second edge of the shelf structure, wherein the second axis intersects the first axis and the second axis is oriented substantially parallel to a plane defined by a plurality of rungs on a ladder when the shelf structure is mounted on the ladder; and
an attachment structure affixed to the shelf structure for removably mounting said shelf structure on said ladder.

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.

15. A shelf apparatus comprising:
-
a substantially planar shelf structure having a plurality of holes adapted to engage at least tools and positioned on a first side proximate to edges of the shelf structure, wherein a first hole of the plurality of holes is formed about a first axis and a second hole of the plurality of holes is formed about a second axis, and both the first axis and the second axis are 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 is formed about a third axis running from a first edge to a second edge of the shelf structure, wherein the third axis intersects the first axis and the second axis, and the third axis is oriented substantially parallel to a plane defined by a plurality of rungs on a ladder when the shelf structure is mounted on the ladder; and an attachment structure affixed to the shelf structure for removably mounting said shelf structure, wherein the attachment structure is adapted for use with at least one of a ladder or a scaffold-system, and said attachment structure is aligned along a fourth axis substantially parallel to said third axis. - View Dependent Claims (16, 17, 18, 19)
