  • a rail in accordance with the invention is generally designated by reference numeral 10.
  • reference numeral 10 in order to form a track 12 ( Figures 2 and 3) in accordance with the invention for dollies used in filming, two rails 10 are located such that they are laterally spaced from and extend parallel to each other, without any interconnection therebetween.
  • the rail 10 is in the form of a metal or metal alloy extrusion and can, not within limits, be manufactured in any desired length.
  • the rails 10 shown in the accompanying drawings are all linear, but, if desired, they can be curved, to permit forming of a track 12 which includes a turn or turns. Further, if desired, a plurality of the rails 10 can be connected end-to-end, to form a track 12 having a length exceeding the length of a single rail 10.
  • the rail 10 has a roughly triangular cross-sectional profile.
  • the rail 10 includes a roughly flat base or foot 14, defining a base of the triangle, and a partly circular cross-sectional profiled crown 16 spaced operatively above the base or foot 14, the crown 16 defining an apex of the triangle.

  • the connecting web 18 slants, from one edge of the base or foot 14 towards the crown 16.
  • the other connecting web 20 has a lower portion which projects normally upwardly from the base or foot 14, and an upper portion which slants towards the crown 16, said upper portion of the connecting web 20 and the connecting web 18 converging towards each other as they near the crown 16.
  • the rail 10 further includes a reinforcement formation located between the base or foot 14, the crown 16 and the two connecting webs 18, 20.
  • the reinforcement formation includes a hollow reinforcement member in the form of a reinforcement tube 22 fast with the base or foot 14 and extending longitudinally along the length of the rail 10, and two reinforcement webs 24, 26 extending between the reinforcement tube 22 and the respective connecting webs 18, 20.
  • the connecting tube 22 has a circular cross-sectional profile, and the reinforcement webs 24, 26 extend generally radially away therefrom towards their respective associated connecting webs 18, 20.
  • a part of the base or foot 14 projects laterally past the aforementioned lower portion of the connecting web 20 to form a flange or lateral extension 28 which extends longitudinally along the length of the rail 10.
  • the purpose of the flange or lateral extension 28 is described in further detail hereunder.
  • two rails 10 are, as briefly described hereinbefore, located alongside each other, such that they are laterally spaced from and extend parallel to each other.

  • the connectors 32 permit fast and easy connecting and disconnecting of two rails 10.
  • FIG. 40 another embodiment of a track 12 in accordance with the invention is generally designated by reference numeral 40.
  • the track 12 is formed over a ditch or a valley (not shown), such that the rails 10 forming part thereof are located at an elevated position above the ground.
