  • the connection area 20 of the vertical diagonal profiles 10 to the chord tube 16 can be located in the joint section SA, in which case, in the connection area 20 of the, in particular, two vertical diagonal profiles 18 a on the chord tube 16 , no additional vertical truss profile 18 and especially no mullion profile 18 b is connected thereto.
  • FIG. 5 A to FIG. 5 C show an embodiment of the truss-type rail 10 with vertical diagonal profiles 18 a which are connected directly to the transverse profiles 24 a . Due to the direct connection to the transverse profiles 24 a , a small eccentricity can be produced on the respective rail tube 12 , 14 , whereby additional bending moments and torque are reduced at the connection areas 22 . This is particularly advantageous if the truss-type rail 10 has a curved shape, as illustrated in FIG. 5 D to FIG. 5 F .
  • FIG. 6 A to FIG. 6 C show the truss-type rail 10 with horizontal diagonal profiles 24 b which run diagonally between the rail tubes 12 , 14 and are connected directly to at least one transverse profile 24 a , preferably two transverse profiles 24 a , near the rail tubes 12 , 14 .
  • the vertical diagonal profiles 18 a are connected directly to the respective rail tube 12 , 14 .
  • the horizontal diagonal profiles 24 b the truss-type rail 10 can be additionally stabilized with regard to horizontal loads and torsional loads.
  • additional mullion profiles 18 b can be omitted. This reduces the increase of wall thickness, as no intermediate step has to be made via mullion profiles 18 b or transverse profiles 24 a and, as described above, the vertical truss profiles can be formed with a larger diameter and smaller wall thickness.
  • FIG. 7 A to FIG. 7 C show a preferred embodiment of the truss-type rail 10 with horizontal diagonal profiles 24 b which are connected to the respective rail tubes 12 , 14 and which has vertical diagonal profiles 18 a connected to the transverse profiles 24 a .
  • a small eccentricity can be produced on the respective rail tube 12 , 14 by connecting the vertical diagonal profiles 18 a directly to the transverse profiles 24 a .
  • locally occurring bending moments can be further reduced.
  • this results in a low bottom eccentricity on the chord tube 16 and a low top eccentricity on the respective rail tube 12 , 14 .
  • the resulting reduction in local secondary stresses can enable an improved global load-bearing behavior.
  • a local vertical load direction is understood to be the vertical load into or out of the seat in the vehicle's local reference frame of the carriage arrangement 32 .
  • This load direction represents the main load direction in the roller coaster arrangement 30 within the meaning of the invention. This means that the largest sharing in terms of amount are to be expected in this direction.
  • the invention relates to a roller coaster arrangement 30 in which the local vertical load direction is substantially perpendicular to a straight line in the compartment plane through left and right-hand rail tubes 12 , 14 .
  • the chord tube 16 is therefore located between the two rail tubes 12 , 14 as seen in the local vertical direction or main load direction.
  • a truss-type rail 10 in the form of a three-chord rail is provided for an amusement ride which only has two rail tubes 12 , 14 directly passable with a car arrangement 32 and only one non-passable chord tube 16 , wherein the local vertical load or main load exerted on the truss-type rail 10 by traveling over the rail tubes 12 , 14 by the car arrangement 32 always has a direction which is substantially perpendicular or perpendicular to the rail plane and/or substantially parallel or parallel to the compartment plane of the rail tubes 12 , 14 .
  • the chord tube 16 is, in the local vertical load direction or main load direction, always located below or behind (in the case of load direction into the seat) the rail plane of the rail tubes 12 , 14 . Furthermore, the chord tube 16 is, in the local vertical load direction or main load direction, always located below or behind (in the case of load direction into the seat) both the one and the other rail tube 12 , 14 . Furthermore, the chord tube 16 is, in the local vertical load direction or main load direction, always located below or behind (in the case of load direction into the seat) and between both rail tubes 12 , 14 .
  • a roller coaster arrangement 30 which includes a car arrangement 32 and at least one truss-type rail 10 , where the at least one truss-type rail 10 includes the aforedescribed rail tube/chord tube arrangement corresponding to the local vertical load direction.
