Definitions

• the present invention relates, in general, to the production of model rails for miniature trains using wire rods of different metals and, more particularly, to a model rail for miniature trains, and a method of producing such a model rail by primarily rolling a copper wire rod or a red brass wire rod to form a rail body, and secondarily rolling a stainless steel wire rod, aluminum wire rod or cupronickel wire rod to form a fitting bar which is then seated along the head of the rail body, and finally rolling the rail body having the fitting bar to integrate them into a single body.
• Model rails for model trains have been designed and constructed in the same manner used to design and construct
• the model rails related to this invention are designed and produced for sale to miniature collectors or persons having interest in driving miniature trains .
• miniature trains have been typically produced by rolling a stainless steel wire rod, a brass wire rod or a cupronickel wire rod to form a desired model rail, which has the same shape as that of a real rail .
• the rails are electrically activated to move the train along the railway.
• the rail body is produced through rolling a copper wire rod or a red brass wire rod, thus having higher electric conductivity than that of conventional model rails made of stainless steel wire rods, yellow brass wire rods, or cupronickel wire rods. This allows a miniature train to smoothly move along a railway.
• a bar holding groove is formed along the head of a rail body made of copper or red brass, while a fitting bar made of a stainless steel wire rod, an aluminum wire rod, or a cupronickel wire rod is assembled with the rail body by engaging with the bar holding groove.

• This step is to produce a fitting bar 110, which is assembled with the head of a rail body 100 of a model rail M according to this invention.
• This fitting bar 110 is produced through rolling a stainless steel wire rod, a cupronickel wire rod (70% Cu + 18% Zn 4- 12% Ni) , or an aluminum wire rod. In such a case, the wire rod having a circular cross-section is rolled to form a fitting bar 110 having a desired cross- section.
• the cross-section and size of the fitting bar 110 correspond to those of a bar holding groove 101 formed along the head of the rail body 100.
• the fitting bar 110 has a rectangular cross-section with a fitting flange 111 continuously formed along the lower edge of each side surface of the fitting bar 110 as shown in Figs. 2 and 3.
• the bar holding groove 101 has a fitting slit continuously formed along the lower edge of each side surface of the groove 101.
• the fitting bar 110 it is preferred to produce the fitting bar 110 through a cold rolling process.
• the cold rolling process is so-called "a room temperature rolling
• the fitting bar 110 is produced through a rolling process, in which a linear groove 112 is formed along the lower surface of the fitting bar 110.
• each side surface of the linear groove 112 is longitudinally toothed, while each side surface of the head of the rail body 100 of the model rail M is toothed in an axial direction. Therefore, the fitting bar 110 of the second embodiment is fitted over the head of the rail body 100 in a manner similar to that of an LM guide block, which has been widely used in the precision industrial field.
• a rail body 100 is produced through a rail body forming step S2.
• the fitting bar 110 is integrated with the rail body 100 to form a resulting model rail, along which a miniature train runs.
• a copper wire rod (Cu) or a red brass wire rod (90% CU + 10% Zn) is rolled to form a desired rail body 100 having a predetermined cross-section.
• the bar holding groove 101 is formed along the top surface of the head of the rail body 100 so as to seat the fitting bar 110 produced at the step SI on the head of the rail body 100.
• a fitting slit 102 is continuously formed along the lower edge of each side surface of the bar holding groove 101. In such a case, the rail body 100 is formed through a cold rolling process.
• the fitting bar 110 and the rail body 100 are produced through rolling different metals. That is, the rail body 100 is made of copper (Cu) or red brass (90%
• the fitting bar 110 seated in the bar holding groove 101 of the head of the rail body 100 is made of stainless steel, cupronickel or aluminum which is white and shiny, so the fitting bar 110 has a shiny effect as if it was abraded due to repeated frictional contact of the rail with the wheels of a train over a lengthy period of time.
• the model rail made of different metals according to this invention thus has the sense of being real.
• the fitting bar 110 After forming the fitting bar 110 through the step SI and forming the rail body 100 through the step S2, the fitting bar
• the rail body 100 with the fitting bar 110 is secondarily rolled under pressure, thus being compressed. Due to compression through the rolling under pressure, the fitting bar 110 is integrated with the rail body 100 to form a half-finished rail.
• the half-finished rail is fabricated with two parts made of different metals, so it accomplishes a desired shiny effect as if it was abraded due to repeated frictional contact.
• the fitting slits 102 of the rail body 100 and the fitting flanges 111 of the fitting bar 110 are compressed together and strongly integrated into a single body, so the fitting bar 110 is not undesirably removed from the rail body
• the model rail according to the present invention is fabricated with a rail body 100 made of copper (Cu) or red brass (90% CU + 10% Zn) , and a fitting bar
• the model rail produced using different metals according to the present invention has higher electric conductivity than that of conventional model rails made of stainless steel, yellow brass, or cupronickel. Due to the rail body being made of red brass, the model rail of this invention has a color similar to that of a real rail. In addition, the red brass of the rail body easily oxidizes to change its color when coming
