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 come from 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.
  • the document of patent application FR-A-2 689 077 A1 discloses an air track made from the pipe of rectangular cross-section with at least two channels, or ducts, separated by one or more inner, vertical walls which both stiffen the pipe and make possible to provide compressed air to selected ducts.
  • the glider hovers on the air cushion created between the glider and the air track by the jets of air exhausted through the orifices in the top surface of the air track.
  • the glider is furnished with lateral, vertical stops preventing it from falling down from the track.
  • the lateral gaps formed between the glider's vertical stops and adjacent vertical, lateral walls of the air pipe play minor role in creation of the air cushion, because compressed air is not directly supplied into these gaps.
  • the lateral gaps dimensions namely their height and width are not really important in FR-A-2 689 077 A1 .
  • This document gives no suggestion on the lateral gaps width, and the gaps vertical dimension may be described only as "smaller” if compared to the air track width.
  • the patent documents US-A-4 714 155 and US-A-4 718 539 disclose the air tracks made of a pipe (double pipe in the document US-A-4 714 155 ) of rectangular cross-section fastened to the support. These air tracks have additional sets of orifices, or nozzles, pierced in the side walls of the air pipe. The jets of compressed air outflowing through these orifices contribute to the build-up of the air cushion between the glider and the air track, and increase stability of the glider's movement along the track.
  • these patent documents give no hint on the lateral gaps width either.
  • An optimum solution shall be elaborated.
  • Patent document US-A-3 209 702 discloses resilient pads
  • patent application DE-A-102 39 661 A1 discloses spring steels, both employed between a railway track and a support.
  • the substance of the invention is the air track consisting of double aliminium pipe with rectangular cross-section, long rigid support and the glider, fit with the springs that pull down the track pipe toward the support, which allows the track pipe to move with regard to the support.
  • the height of lateral gaps formed between the glider and the track pipe and filled with compressed air is less than 0.25 of the air track width, and the width of each of lateral gaps filled with compressed air and formed between 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 orifices in the top surface of the pipe are placed close to the track pipe edges, and the track pipe central part which covers about 70% of the track pipe total top surface has no orifices, and the 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 air track according to the invention is in a possibility for the track pipe to move above the support, then 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.
  • Another virtue of the air track according to the invention is in that the lateral gaps filled with compressed air and formed between the track pipe and the glider, because of their 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.
  • Yet another virtue of the air track according to the invention is in that the air which flows out of the orifices situated close to the track pipe edges, far from the track pipe longitudinal axis, lifts the glider and additionally prevents it from reeling and grinding against the track pipe.
  • Still another virtue of the air track according to the invention is in advantageous application of easily accessible, precisely manufactured double aluminium pipes of rectangular cross-section which are commonly 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 with the glider.
  • the air track consists of 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) pull down the track pipe (1) toward the support (2).
  • Lateral gaps filled with compressed air and formed between 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 these lateral gaps is less than 0.2 mm.
  • the orifices in the top surface of the track pipe (1) are placed close to the edges of the track pipe (1), and central part of the track pipe (1) which covers about 70% of the track pipe (1) total top surface has no orifices.
  • the 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.
