Definitions

  • the subject of the invention is the air track, i.e. a device for lifting the bodies of known weights over the ground through the medium of compressed air.
  • the subject of the invention is intended to lift and transport the bodies of considerable weight with very low resistance to motion.
  • the subject of the invention may be used wherever a required information might be an observation of motion of the bodies, not interfered by friction to the ground.
  • the air tracks comprised of the pipe with aeration vents exhausting jets of compressed air lifting a glider are known.
  • the pipes have various cross-sections: round, square, triangular, or rectangular.
  • the glider's shape fits that of the pipe.
  • An inconvenience in use of known air tracks consists in that the gliders lifted on the air-cushion close to the longitudinal axis reel and grind against the track.
  • the substance of the invention which is the air track consisting of the double aliminium pipe with rectangular cross-section, long rigid support and the glider, is an application of the springs that press down the track pipe to the support, which enables the pipe to move with regard to the support.
  • the height of lateral gaps formed by the glider and the track pipe and filled with compressed air is less than 0.25 of the track width, and the width of each of lateral gaps filled with compressed air and formed by the glider and the track pipe is less than 0.2 mm.
  • the glider is fit with the element of considerable mass if compared to the glider's mass and placed so that the glider's mass centre is above the track's surface.
  • the holes in the top surface of the pipe are placed close to the track pipe edges, and the pipe central part which is 70% of the track pipe total top surface has no holes, and the double track pipe and support are made from double aliminium pipe of rectangular cross-section which is used for measuring staff with outer width of 90.5 mm and thickness of 18 mm.
  • a virtue of the solution according to the invention which is the air track consisting of the double aluminium pipe of rectangular cross-section, long rigid support and the glider is in that because of a possibility for the track pipe to move above the support, the track pipe reflects the support's shape and does not bend while influenced by a difference in temperatures of the air conducted from a compressor toward the track pipe and that of the air surrounding the support.
  • a virtue of the solution according to the invention which is the air track consisting of the double aluminium pipe of rectangular cross-section, long rigid support and the glider is in that the lateral gaps filled with compressed air and formed by the track pipe and the glider, because of that they have very low width, less than 0.2 mm each, they prevent the air from escaping from beneath the glider, which makes possible to burden the glider with additional weight, and slight height of lateral gaps, lesser than 0.25 of the track width, does not increase meaningfully the resistance to motion.
  • a virtue of the solution according to the invention which is the air track consisting of the double aluminium pipe of rectangular cross-section, long rigid support and the glider is in that the air which gets out of the holes situated close to the track pipe edges, far from the track longitudinal axis, lifts the glider and additionally prevents it from reeling and grinding against the track pipe.
  • a virtue of the solution according to the invention which is the air track consisting of the double aluminium pipe of rectangular cross-section, long rigid support and the glider is in advantageous application of easily accessible, precisely manufactured double aluminium pipes of rectangular shape which are used for measuring staff.
  • fig. 1 shows the lateral view of the air track
  • fig. 2 shows the cross-section of the air track without the glider
  • fig. 3 shows the cross-section of the air track.
  • the air track consists of the double aluminium pipe (1) of rectangular cross-section, long rigid support (2) and the glider (4) fit with the element (5) of considerable mass if compared to the glider's (4) mass and placed so that the glider's (4) mass centre is above the track's (1) surface.
  • the springs (3) press down the track pipe (1) to the support (2).
  • Lateral gaps filled with compressed air and formed by the glider (4) and the track pipe (1) are of height lesser than 0.25 of the track pipe (1) width, and the width of each of lateral gaps formed by the glider (4) and the track pipe (1) is less than 0.2 mm.
  • the holes in the top surface of the pipe (1) are placed close to the edges of the track pipe (1), and central part of the pipe (1) which is 70% of the track pipe (1) total top surface has no holes.
  • the double track pipe (1) and the support (2) are advantageously made from double aliminium pipe of rectangular cross-section which is used for measuring staff with outer width of 90.5 mm and thickness of 18 mm.
