Description

TECHNICAL FIELD AND BACKGROUND OF THE INVENTION

The present invention relates to the field of scaffolding and ladders and particularly to field of accessories for scaffolding and ladders. The invention includes an attachable accessory container, such as a tray, tub, box or bucket, which extends vertically beyond the top of various types of structures used to gain height above a supporting surface, particularly where the user requires access to implements while on the structure. Descriptions and definitions of these structures, such as ladders and scaffolds, are found at http://www.ladders.net/type, and include step, extension, platform, telescoping and folding ladders, and various types of scaffolds.

For many years, humans have utilized ladders in order to extend a person's reach. Ladders have been employed in order to climb from one-surface to a higher location.

Ladders have broad applicability and are often utilized in order to afford access to areas otherwise not accessible.

Ladders have many uses and, as is often the case, a ladder is utilized not simply to observe an area but to perform an operation in or on a particular area. In such uses, it is quite common that the person using the ladder will require the use of tools or other materials and implements while using the ladder. An electrician may use wires and wire cutters atop a ladder. A plumber may use a pipe wrench atop a ladder. Decorators and painters may use paint brushes and brick masons may use trowels and mortar while atop a ladder.

Ladders may include some accessories that attempt to aid those who use ladders. For example, a folding step ladder may include a hook attached to a step of the ladder usable for hanging a paint bucket. Similarly, a step ladder may include a folding platform attached to a ladder for holding implements.

In most situations, however, such accessory holders are positioned at or below the level of the uppermost steps of the ladders. As a result, users must reach downward, sometimes very far downward, to grasp implements positioned on the accessory holder. Reaching down in such a manner can be inefficient as well as both difficult and dangerous. If a user of a ladder has to reach far down to obtain his tools, time may be wasted in reaching far down. Similarly, the user of the ladder expends energy and must bend and lift in order to reach implements placed on accessary holders of the prior art. Worse still, the user of a ladder may lose his balance when so reaching down and may risk falling from the ladder. Thus, there is a need in the art for an accessory holder that does not require the user of a ladder to reach far to place and access tools and other implements desirable for use while atop a ladder.

Additionally, ladders are lengthy and space consuming. Storage and transportation space for ladders may be of concern to some users. As such, ladder height may be limited not by the areas to be accessed but by the capacity for storage and transport. Ladders necessary to reach or perform a particular function may not be tall enough in certain circumstances. Further it is common for the top step or possibly the top two or three steps of a ladder to be unsafe for use. These steps or rungs are often labeled as such. Nevertheless, for many reasons, users do utilize and stand upon upper level steps even though they may be specifically labeled as not for use as a step. Thus, the above noted problems are exacerbated when users climb above the top steps and then attempt to reach even further down for tools and implements. Thus, there is a further need for an accessory holder that improves safety and reach above the upper steps of a ladder. There is also a need for a ladder accessory holder that may be utilized at elevated heights where storage or transportation space for the ladder may be limited.

Further, there is a need in the art for a ladder accessory holder that is adjustable in height by a particular user and for a particular application.
