RELATED APPLICATIONS

This application claims priority from U.S. Provisional Patent Application No. 60/393,326, filed Jul. 1, 2002, which is hereby incorporated by reference for its supporting teachings.[0001]

FIELD OF THE INVENTION

The present invention relates generally to outer footwear worn by rooftop workers, such as roofing material installers, who perform work on surfaces with relatively steep pitches. Specifically, the present illustrated embodiments describe a form of outer footwear that is designed to aid a rooftop worker in more safely and effectively performing his/her labor by allowing him/her to negotiate a steep surface with minimal foot slippage or heat transfer, and with minimal shingle, or other surface, scarring. BACKGROUND OF THE ILLUSTRATED EMBODIMENT(S) AND PRIOR ART

Rooftop workers are subject to a myriad of risks while performing their labors. Among these risks are the ever present concerns of slipping and falling off of a roof or similar structure, and developing foot pain, or other medical complications, due to excessive heat transfer from the work surface. To mitigate these risks, there are several methods or tools utilized by rooftop workers to protect against slippage and to reduce the transfer of heat from the roof, or similar, surface to the foot of the worker. For example, rooftop workers often utilize ropes or straps to secure themselves to the structure upon which they are working. In addition, they wear soft-soled shoes to increase traction. However, these typical and well-known methods have inherent problems.

Using ropes to secure a worker to a roof, or “tying off” as it is regularly referred to, does not protect a worker from the initial slip and fall. In effect, an injury may have already occurred through the act of slipping and falling on a roof surface before a worker falls from the structure. Furthermore, tying off is a tedious and cumbersome duty, and one that many rooftop workers simply ignore. It is well recognized that most roofers do not tie off unless explicitly required to do so by a job foreman or OSHA representative. As a result, many injuries occur at the point of a slip as well as at the point of a fall from the work structure.

In addition, many soft-soled shoes do not adequately provide the level of traction required to prevent slipping when a worker is carrying a heavy load or bending in an unusual or physically awkward or unbalanced position. Further, soft-soled shoes do not prevent a transfer of heat from the work surface to the foot of the worker and contribute to extreme discomfort and resulting medical complications. Soft-soled shoes often require the worker to remove granules of asphalt based shingles from the shoes after working on a roof to install the same. The accumulation of these granules can create an unsafe condition by coating the underside of the shoe and eliminating the traction element from the soft sole, thereby increasing the chance for a worker to slip and fall.

Shingle scarring is also a common problem for installers of asphalt, and other types of, roofing shingles. As the shingle surfaces heat up due to solar exposure, the bond between the shingle underlayment and the coating of asphalt granules begins to soften. As a result, in hot climates, the surface of the shingles may become easily scarred or damaged where a worker has trodden on the same. This occurs primarily because the shoes of the worker do not adequately adhere to the surface of the shingle to prevent slippage. As the workers shoe slips and slides across the shingle, the surface of the shingle becomes scarred or damaged.

Thus, it can be clearly recognized that there is a need for a device designed to provide the worker with the traction required to prevent, or drastically reduce, the amount of slippage resulting from work performed on steep pitched surfaces, and to prevent, or drastically reduce, the amount of heat transferred from the work surface to the foot of the worker. It is also clearly recognized that there is a need for a similar device that is designed to prevent shingle scarring or damage resulting from worker slippage.

SUMMARY OF THE ILLUSTRATED EMBODIMENT(S)

The present invention relates generally to outer footwear worn by rooftop workers, such as roofing material installers, who perform work on surfaces with relatively steep pitches and, often, slippery points of contact. Specifically, the present illustrated embodiments describe a form of outer footwear, or shoe pad, that is designed to aid a rooftop worker in safely performing his/her labor by allowing him/her to move about a steep surface with minimal foot slippage or heat transfer. The present illustrated embodiments describe a pad within which conventional shoes or boots may be inserted.

More particularly, a unitary cut or mold of sponge-like and firm material, such as composite or foam rubber, is designed to roughly mirror the shape of a worker's shoe or boot.

Remarks about the Illustrated Embodiment(s) [0033]
The illustrated embodiment(s) have taught several improvements over the prior art that will be readily understood by a skilled artisan after review of the present disclosure. For example, it has been discussed that the unique combination of straps and a unitary base material, made from composite or foam rubber, will allow a rooftop worker to more safely move about a roof, or similar steep pitched surface, will reduce damaging heat from transferring through the shoes or boots of a worker, and will reduce the amount of scarring or damage to roofing materials. [0034]
Based on the reasons outline above, the present invention may serve to reduce costs to roofing contractors by reducing the amount of replacement material(s) needed to compensate for scarred or damage roofs. In addition, the present invention may drastically reduce the incidence of slip related injuries for rooftop workers, and may reduce the incidence of heat induced foot problems and pain incurred by these workers. [0035]
It is pointed out, if it has not already been made clear, that the backbone of the illustrated embodiment(s) is the ability of the present invention to allow a roof-top worker to more safely install materials, carry materials, and simply move about a roof or similar steep pitched surface. [0036]
Variations of the Illustrated Embodiment(s) [0037]
It is understood that the above-described arrangements are only illustrative of the application of the principles of the present invention. Numerous modifications and alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present invention and the appended claims are intended to cover such modifications and arrangements. [0038]
For example, although the illustrative embodiment(s) have/has described the use of an oval shaped unitary base, the present invention also contemplates the use of a rectangular or oblong shaped base. In addition, although the presently illustrated embodiments describe the use of composite and/or foam rubber base materials, a water-resistant material may also be utilized within the scope of the present invention. Any material of similar density and performance as composite or foam rubbers may be implemented as the base material for the present invention. [0039]
Also, any number of methods for fastening the straps to the unitary base, including but not limited to stitching, snaps, rivets, adhesive, silicon, and Velcro, are envisioned within the scope of the present invention. Silicon or a similar flexible form of adhesive is preferred in order to compensate for the stresses of wear on the unitary base. Any number of connectors for securing the straps to one another, including but limited to buckles, D-buckles, nylon straps, snaps, Velcro, and buttons, are also envisioned within the scope of the present invention. [0040]
Thus, while the present invention has been shown in the drawings and fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiment(s) of the invention, it will be apparent to those of ordinary skill in the art that numerous modifications, including, but not limited to, variations in size, materials, shape, form, function, and manner of operation, assembly, and use may be made, without departing from the principles and concepts of the invention as set forth in the claims.
