Description
- This application claims the benefit under 35 U.S.C. 119(e) of U.S. Provisional Application No. 60/552,628 filed on Mar. 12, 2004.
- 1. Field of the Invention
- This invention relates to an electrically isolated industrial coated wire mesh fence, and more particularly to an electrically isolated and insulated fence assembly for use in an industrial plant to prevent injuries from electrocution.
- 2. Description of the Prior Art
- Conventional perimeter fences are well known in the art, including one of the most common types of coated wire mesh or chain link fences for surrounding operating machinery. However, practitioners of those inventions have become aware of certain problems, which are presented by those prior art inventions. One particular problem that has plagued users has been industrial accidents which may occur in an industrial plant when a worker comes into contact with an electrically charged fence. An electrically charged fence may occur accidentally when an errant live wire comes into contact with a metal fence. This accidental electrification of the fence makes any worker that comes into physical contact with the fence a prime candidate for electrocution.
- Therefore, it would be an advantage to the industry to provide an electrically insulated and isolated fence assembly so that a worker that contacts an accidentally electrified fence assembly would not have a chance to become electrocuted. It would also be desirable, in the industrial plant setting, to have an electrically insulated and isolated fence assembly which is always in an electrically insulated state in order to prevent electrocutions.
- In accordance with the above-noted advantages and desires of the industry, the present invention provides an electrically insulated and isolated fence assembly which remains insulated and isolated at all times due to its construction. The fence assembly of the present invention essentially includes an electrical isolation jacket to be worn around all of the metal mesh fence sections so that any one who touches the fence is protected from electrocution. The fence assembly may include an extruded fence post and rail design which is thereafter either PVC coated or is adapted to receive any other type of electrically insulating post cover made of any suitable moldable or coatable material, such as a plastic material including thermoplastic or thermoset materials, including but not limited to polypropylene, polyethylene, polyurethane or any other suitable plastic material. Materials having the property of being electrically insulating work well for this application. In the preferred embodiment, including the design of such an extruded cover piece, the cover is combined with the plastic coating or electrically insulating layer covered material to be utilized over the metallic portion of the fence, thereby yielding an electrically insulated and isolated fence assembly which meets or exceeds all of the advantages and desires of the industry.
- Although the invention will be described by way of examples hereinbelow for specific embodiments having certain features, it must also be realized that minor modifications that do not require undo experimentation on the part of the practitioner are covered within the scope and breadth of this invention. Additional advantages and other novel features of the present invention will be set forth in the description that follows and in particular will be apparent to those skilled in the art upon examination or may be learned within the practice of the invention. Therefore, the invention is capable of many other different embodiments and its details are capable of modifications of various aspects which will be obvious to those of ordinary skill in the art all without departing from the spirit of the present invention. Accordingly, the rest of the description will be regarded as illustrative rather than restrictive.
