Referring initially to the drawings, FIG. 1 illustrates a perspective view of one potential embodiment of a refrigerant-cylinder leveling platform device 100 of the present invention while unfolded and standing in accordance with the disclosed architecture. The device 100 is a levelable support structure configured to facilitate the charging of air conditioning systems while maintaining mechanical stability across a range of surface conditions. The device 100 is designed to provide a level platform that minimizes tilting or misalignment of refrigerant cylinders during HVAC servicing operations. This configuration helps prevent improper refrigerant flow, inaccurate system pressure readings, or potential system malfunction due to uneven placement. Furthermore, the device 100 enhances safety by securing the refrigerant cylinder in a stable position to mitigate the risk of rolling-induced injury or equipment damage.
The device 100 may be comprised of a body 102 of any geometric shape such as, but not limited to, rectangular, square, circular, polygonal, or elliptical configurations. The body 102 is comprised of a frame 104 preferably made from rigid and corrosion-resistant materials such as, but not limited to, stainless steel, aluminum, powder-coated carbon steel, high-strength polymer composites, or weather-resistant metal alloys. The body 102 is comprised of a flat upper surface 106 configured to receive and support an air conditioning refrigerant cylinder. In one embodiment, the upper surface 106 may be comprised of a friction-enhancing material 108 such as, but not limited to, thermoplastic elastomer overlays, vulcanized rubber sheets, sand-textured polymer coatings, diamond-plate aluminum, or abrasive composite laminates, or other textured material.
