By a News Reporter-Staff News Editor at Politics & Government Week -- According to news reporting originating from Washington, D.C. , by VerticalNews journalists, a patent application by the inventors Schilke, Alan ( Hayden, ID ); Grubb, Fred ( Hayden, ID ); Bachtar, Dody ( Hayden, ID ), filed on September 26, 2013 , was made available online on January 30, 2014 . The assignee for this patent application is Rocky Mountain Coasters, Inc. Reporters obtained the following quote from the background information supplied by the inventors: "Roller coasters, other amusement park rides, ski lifts and other rolling vehicle people moving devices frequently have a need for complicated tracks to either provide a dynamic experience or follow rugged terrain. As such, many of these tracks for such rolling vehicles are fabricated from steel pipe, which is traditionally heated and bent to acquire its desired shape. "Unfortunately, heating and manipulating steel rod or steel pipe in such a way, and permanently bending such material, causes significant fatigue in the material. This fatigue is then existent in the resultant structure before a stress or load is applied to such apparatus, such as inherent stresses in the installation of the track (static loads) and dynamic loads applied to the track (e.g. a passing roller coaster carriage). Over time, the culmination of the manufacturing stresses, static stresses and dynamic stresses require that the traditional pipe track be replaced frequently over time. "Further, when steel rod or steel pipe is heated and bent into complex designs, the rod or pipe does not necessarily bend as desired. Metal will typically seek to bend at its weakest point or where the most force is applied over a span. As such, the end result of a fabricated steel structure may not exactly match the desired design, which either results in repeated attempts of fabrication or settling for a less than optimal result. In particular, structural and material efficient designs such as triangular tubing, square or rectangular tubing, or other metal tubing that has airspace within the cross section of the steel structure can be vulnerable to both deformation and cracking. "At the present time, metal (namely steel) roller coasters are fabricated from round, straight steel rod or steel pipe which are bent into desired formations for the necessary roller coaster application. "Based on our knowledge of the industry, there are no roller coasters in existence where the tracks are fabricated from stock planar metal material that has been cut and welded together to form the desired curve track. Such an invention, if possible, would be a highly desirable benefit as the newly developed track, which has not been bent, deformed or heated, would retain its original strength without unnecessary fatigue placed on the material by traditional bending methods. With such superior material fitness in light of the absence of fatigue during manufacture, the resulting structure or roller coaster track would be far stronger and last longer than traditional approaches. Such strength and durability, therefore, can effectively result in roller coasters and other structures being built on a larger scale or more efficient budget as compared to earlier traditional approaches. "Therefore, what is needed in the art of amusement park rides and other complex curved structures is a new approach to the fabrication and manufacture of an elongated, curved structure such as a roller coaster track. Preferably, such an improved track minimizes manufacturing stresses, creates a desired result, and further preferably reduces the costs of materials and manufacture when compared to traditional roller coaster, amusement ride, ski lift, staircase or other elongated structures." In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "Embodiments of the present invention are generally directed toward a new method to fabricate an elongated, curved structure such as an amusement park roller coaster track or spiral staircase support. Once a three dimensional design of the elongated structure is determined, specialized software can be utilized to map out the various pieces of flat material to be cut out--pieces that will ultimately become the components of the elongated, curved structure. Such component pieces, in preferred embodiments, are cut into their respective designed shapes using a plasma cutter or other conventional device and are subsequently attached together (e.g. welded) to form a structurally sound elongated, curved structure. "In one aspect, embodiments of the present invention comprise a method of designing and fabricating such an elongated, curved structure. "In another aspect, such a process also creates a new product of the process, an apparatus which is a curved, elongated structure that comprises a plurality of planar components fixably in permanent communication with one another. "In yet another aspect, a roller coaster can be built upon such an elongated, curved structure. In still another aspect, a ski lift or other people mover can be built upon such an elongated structure that does not require conventional wires or round tracks. Lastly, though in no way limiting the scope of the present invention, a curved staircase or architectural structure can be built upon such an elongated, curved structure that does not require heating, bending or deformation of traditional metal beams.
