DETAILED DESCRIPTION

[0020] The innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth to provide a thorough understanding thereof. It may be evident, however, that the innovation can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form to facilitate a description thereof. Various embodiments are discussed hereinafter. It should be noted that the figures are described only to facilitate the description of the embodiments. They are not intended as an exhaustive description of the invention and do not limit the scope of the invention. Additionally, an illustrated embodiment need not have all the aspects or advantages shown. Thus, in other embodiments, any of the features described herein from different embodiments may be combined.

[0021] As noted above, there exists a long-felt need in the art for a refrigerant-cylinder leveling platform device that enables technicians to maintain a level surface for accurate refrigerant charging on uneven ground. There also exists a long-felt need in the art for a refrigerant-cylinder leveling platform device that improves user safety by preventing cylinder movement or tipping. Moreover, there exists a long-felt need in the art for a refrigerant-cylinder leveling platform device that provides foldable and compact storage for convenient transport between job sites.

[0022] The present invention, in one exemplary embodiment, is comprised of a refrigerant-cylinder leveling platform device. The device serves as a levelable support structure intended to aid in the charging of air conditioning systems by delivering a stable and level platform for refrigerant cylinders. By minimizing tilting or misalignment during HVAC servicing, the device prevents inaccurate refrigerant flow, incorrect system pressure readings, and operational faults arising from uneven placement. Additionally, the device improves safety by securing the refrigerant cylinder, thereby mitigating the potential for injury or equipment damage.

[0023] The structure is comprised of a body incorporating a flat upper surface that supports refrigerant cylinders and may include friction-enhancing materials to prevent slippage. To sustain traction in wet conditions, drainage features such as holes or channels may also be present. A raised perimeter edge may also be included to assist in retaining objects placed on the upper surface.

[0024] The body incorporates multiple telescopic legs, each independently adjustable in height. Each leg is equipped with a locking mechanism to secure the selected length and terminates in a foot designed for ground stability across various surfaces. The foot may feature a pivot point allowing angular adaptation to irregular terrain and may be further enhanced with textured materials to increase traction.

[0025] Each leg is mounted to the frame using a hinge capable of rotating up to 180 degrees, enabling inward folding for compact storage or outward deployment for use. A locking mechanism is included to secure the rotational position of each leg once folded or extended. At least one integrated level may be provided for accurate platform leveling, while one or more handles may be included for ease of transport. The upper surface may also function as a temporary support area for HVAC tools or equipment during servicing.

[0026] The invention further includes a method of use comprising the steps of providing the device with a frame, a flat upper surface, telescopic legs featuring locking mechanisms, pivotable feet, and rotational hinges with corresponding locking mechanisms, along with at least one integrated level. The legs are first unfolded and rotated outward, followed by securing them in place. Each leg is then individually adjusted to level the upper surface as indicated by the level. A refrigerant cylinder is subsequently placed on the surface, which may also be used to support tools temporarily during service activities.

[0027] As a result, the device offers significant benefits by maintaining a level surface that facilitates accurate refrigerant charging on uneven terrain. The inclusion of adjustable legs improves platform stability and reduces cylinder movement, thereby enhancing user safety. Foldable legs and integrated handles further contribute to ease of transport and compact storage, supporting practical deployment in various field conditions. Through these features, the device addresses and resolves limitations present in prior known methods of charging refrigerant cylinders.

[0028] 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.

[0029] 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. The surface 106 may also feature drainage features 107 such as, but not limited to, holes or channels, to prevent pooling of liquid on the surface 106 under humid or rainy conditions, thereby maintaining traction. In one configuration, the frame 104 may be comprised of a raised perimeter edge 110 extending vertically above the plane of the surface 106 to further retain cylinders or other objects on the surface 106.

[0030] The frame 104 is further comprised of a plurality of legs 112. Each leg 112 is preferably telescopic, allowing independent height adjustment, as seen in FIG. 3. Each leg 112 may be comprised of a locking mechanism 114 such as, but not limited to, spring-loaded clamps, threaded collars, cam-based wedges, or ratchet-based systems to lock the length/height of the leg 112 as desired. Each leg 112 may terminate in a foot 116 designed to improve ground contact stability. The foot 116 may be shaped in various configurations such as, but not limited to, flat, dome-shaped, angled, spiked, or hemispherical forms, to accommodate different outdoor surface types, including gravel, soil, concrete, sand, grass, or asphalt. In one embodiment, the foot 116 may be rotatable via a pivot point 117 such as, but not limited to, a ball-and-socket joint, a hinge-mounted axis, a universal joint, or a swivel plate bearing. The pivot point 117 may enable the foot 116 to self-adjust the angular orientation in response to inclined, curved, or irregular ground surfaces, thereby distributing load evenly and enhancing platform stability. The foot 116 may be comprised of a texture 118 such as, but not limited to, ribbed thermoplastic, knurled rubber, chevron-patterned polymer, studded elastomeric coatings, grit-embedded surfaces, etc., to enhance traction and reduce slippage.

[0031] In one embodiment, each leg 112 may be attached to the frame 104 via a hinge 120 that enables angular rotation of up to 180 degrees. The hinge 120 may permit folding of each leg 112 inward against the underside of the body 102 for compact storage, as seen in FIG. 2. Alternatively, the hinge 120 may allow for outward rotation (up to 180 degrees) of each leg 112 to deploy the legs into positions suitable for leveling the platform. The hinge 120 may be comprised of a locking mechanism 121 such as, but not limited to, a spring-loaded latch, detent pin, friction lock, twist-to-lock cam, or sliding bolt, configured to secure the rotational position of each leg 112 once deployed or folded, thereby ensuring stability during use or transport. In certain embodiments, the locking mechanism 121 may be manually operated or automatically engaged based on the leg's angular displacement. The device 100 may also be comprised of at least one integrated level 124 such as, but not limited to, bubble levels, digital inclinometers, spirit levels, etc. For enhanced portability, the device 100 may be equipped with one or more integrated handles 126. The device 100 may also function as a multi-purpose utility station wherein the upper surface 106 may provide a stable platform for temporarily staging tools, electrical control units, HVAC interface modules, fasteners, or delicate electronic components during air conditioning service operations.

[0032] The present invention is also comprised of a method of using 200 the device 100, as seen in FIG. 4. First, a device 100 is provided comprised of a body 102 having a frame 104, a flat upper surface, a plurality of legs 112 each comprising a locking mechanism 114, a foot 116, a hinge 120 with a locking mechanism 121, and at least one integrated level 124 [Step 202]. Then, the legs 112 are unfolded via the hinges 120 and rotated outward up to 180 degrees until fully deployed, wherein each hinge 120 is locked in place using the locking mechanism 121 to secure the angular position of each leg 112 [Step 204]. Next, the telescopic length of each leg 112 is individually adjusted to compensate for the ground surface inclination (as seen in FIG. 3), using the locking mechanism 114 to secure each leg 112 at a desired height, thereby leveling the upper surface 106 as indicated by the integrated level 124 [Step 206]. Next, an air conditioning refrigerant cylinder is placed on the upper surface 106 [Step 208]. Finally, during HVAC servicing, the upper surface 106 may also be additionally used to temporarily stage tools or equipment [Step 210].
