The title of this invention is: Roof Shoe Pad. This invention is for replaceable shoe pads which are attached by releasable adhesive to a wearer's ordinary shoe sole(s) and are designed to improve the traction, footing and comfort of a wearer, when walking or working on a inclined roof, and to provide scuff protection for roof surfaces.
The shoe pads are composed of foam or soft rubber or other material with similar deformable and friction characteristics. In a preferred embodiment the shoe pads are comprised of geometric solids with length, width, and height dimensions. The width and length of the shoe pads are preferably equal to or somewhat larger than the length and width of the wearer's shoe soles. In a preferred embodiment, foam shoe pad(s) attach directly to the soles of a wearer's ordinary shoes by releasable adhesive.
The height of the shoe pads is nominally one inch but may vary with the type of material used for the pad. In a preferred embodiment the shoe pads are employed by removing a adhesive protectant sheet from the adhesive and attaching the pad to the wearer's ordinary shoe sole(s).
When the pads are no longer needed, they are peeled from the wearer's shoes.
BACKGROUND OF THE INVENTION
Persons who work on inclined roofs or have need to negotiate inclined roofs, including homeowners, are subject to risks of foot slippage and consequent falling as well as the inherent discomfort of walking or working on inclined and sometimes uncomfortably hot, roof surfaces. During hot weather, asphalt shingles and similar types of roof surfaces are easily scuffed or scarred by a wearer' shoe soles which can involve costly repair or rework.
Numerous devices have been introduced to address the safety problems of roof workers. Among these are safety ropes, safety harnesses, special ladder devices, and a number of special footwear devices. None of these are without inherent shortcomings. Tying roof workers with ropes and harnesses does not improve their foot traction, provides only secondary safety from loss of footing, and negatively impacts productivity. It is a readily observable fact that most roof workers do not use such devices. Homeowners and do-it-yourself persons who negotiate roofs are also exposed to foot slippage.
Some of the footwear devices previously introduced for roof workers involve complex mechanical attachments that are expensive and cumbersome to attach and adjust or to keep adjusted. Some require frequent readjustment as the wearer shifts position or direction on a roof. Attachments using straps to fasten pads to shoes are shoe size sensitive, uncomfortable, and tend to allow a wearer's foot to roll and twist inside the straps.
Some of the footwear devices previously introduced for roof workers involve special shoes that are too expensive to cost justify for the average homeowner, do-it-yourself roof worker, and for most paid roof workers who are often seasonal and transient.
U.S. Pat. No. 5,259,125 to Gromes, discloses an attachment for a shoe consisting of a partial sole pad made of indoor-outdoor carpet that attaches to a wearer's shoe or boot with straps. That patent also discusses other various designs and devices previously disclosed for use in improving footing for persons working on or negotiating inclined roofs. The Gromes device provides improved but insufficient traction and requires adjustment of holding straps. Foam or soft rubber has greater friction characteristics than the indoor-outdoor carpet disclosed in that invention.
U.S. Pat. No. 5,996,252 to Cougar, discloses a special constructed shoe and replaceable foam or soft rubber pad attachment to the shoe through the use of a hook and loop fastening system. That invention does not allow for attachment of the disclosed pad to a wearer's ordinary shoe thus requiring the wearer to purchase special shoes as well as replaceable pads.
None of the devices of prior art meet all of the needs of simplicity, safety, comfort, work effectiveness and cost effectiveness of persons who regularly work on, or negotiate, inclined roofs and/or of those persons who only occasionally need to negotiate inclined roofs.
SUMMARY OF THE INVENTION
Primary objectives of this invention are to provide a shoe pad attachment that will provide safer footing through improved traction, and increased comfort for the wearer while negotiating a inclined roof surface, and that will also protect the roof surface from shoe damage. A further objective of the invention is an attachment that can be worn on a roof, on the ground, and while negotiating ladders. A further objective is a shoe pad attachment that does not require special shoes.
When a preferred embodiment of this invention, utilizing a rectangular foam pad from one half to one inch thick and somewhat larger in width and length, than a wearer's shoe sole, is attached by releasable adhesive, through a peel-and-stick application, to the wearer's shoe sole, significant advantage is gained in safety, dexterity, comfort and roof scuff protection while the wearer walks or works on a inclined roof and does so at improved cost effectiveness compared to prior art.
