Description

HVAC SUPPORT SYSTEMS AND RELATED METHODSCROSS REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 519,931, filed August 16, 2023, which is hereby incorporated by reference in its entirety.FIELD

[0002] Disclosed embodiments are related to HVAC support systems and related methods. More specifically, systems and methods for elevation of HVAC systems are disclosed.BACKGROUND

[0003] Both residential and commercial properties typically include heating, ventilation, and air conditioning (HVAC) systems to manage the property’s temperature, humidity, and other environmental conditions. HVAC systems, especially those used for large homes or commercial properties, often have a sizeable footprint. Furthermore, the operation of some HVAC systems (e.g., air conditioners) requires the systems to be positioned outdoors to allow for thermal exchange with the open air. Accordingly, HVAC systems are typically placed outdoors on the property, often exposed to the conditions, such as rain, snow, hail, landscaping, debris, dust or sand, animals, and pollution, depending on the location of the property.SUMMARY

[0004] In some embodiments, an HVAC support system includes a plurality of legs configured to elevate an HVAC system, a substantially planar frame, wherein the plurality of legs are coupled to the substantially planar frame, and at least two crossbars releasably locked to the substantially planar frame along a lateral direction, each of the at least two crossbars having a projection oriented normal to a body of the at least two crossbars, wherein the projection of each of the at least two crossbars is configured to prevent lateral movement of the HVAC system relative to the substantially planar frame.

[0005] In other embodiments, an HVAC support system includes a plurality of legs configured to elevate an HVAC system, and a substantially planar frame, wherein the plurality of legs are coupled to the substantially planar frame, wherein the plurality of legs are configured to rotate relative to the substantially planar frame in an unlocked configuration, and wherein the plurality of legs are arranged normal to the substantially planar frame in a locked configuration.

[0006] In other embodiments still, an HVAC support system includes a plurality of legs configured to elevate an HVAC system, a substantially planar frame, wherein the plurality of legs are coupled to the substantially planar frame, a plurality of feet removably coupled to the plurality of legs, and a plurality of shoes removably coupled to the plurality of feet, wherein each of the plurality of shoes form an interference fit with a portion of one of the plurality of feet.

[0007] In some embodiments, a method of supporting an HVAC system includes rotating a plurality of legs relative to a substantially planar frame, the plurality of legs coupled to the substantially planar frame and locking the plurality of legs normal to the substantially planar frame to prevent rotation of the plurality of legs relative to the substantially planar frame.

[0008] It should be appreciated that the foregoing concepts, and additional concepts discussed below, may be arranged in any suitable combination, as the present disclosure is not limited in this respect. Further, other advantages and novel features of the present disclosure will become apparent from the following detailed description of various nonlimiting embodiments when considered in conjunction with the accompanying figures.BRIEF DESCRIPTION OF DRAWINGS

[0021] It should be understood that aspects of the invention are described herein with reference to the figures, which show illustrative embodiments. The illustrative embodiments described herein are not necessarily intended to show all aspects of the invention, but rather are used to describe a few illustrative embodiments. Thus, aspects of the invention are not intended to be construed narrowly in view of the illustrative embodiments. In addition, it should be understood that aspects of the invention may be used alone or in any suitable combination with other aspects of the invention.

[0022] HVAC systems are typically positioned outdoors on a commercial or residential property and are tasked with maintaining a comfortable interior environment through temperature, humidity, and other conditions. Due to their large footprints and weights, as well as connections to nearby systems, HVAC systems are typically positioned close to the ground. Although such arrangements can make installation quick, they may limit a user’s (e.g., a technician or property owner / manager) access to the system, as well as enhance the HVAC system’s exposure to environmental conditions. In some instances, environmental elements (such as rain, snow, hail, landscaping, debris, dust or sand, animals, and pollution, depending on the location of the property) may cause damage to theperformance and longevity of the equipment. For example, in the Northeastern region of the United States, snow, hail, and rain often cause rapid rusting and degradation of HVAC systems’ structural integrity. Given the relative high price of purchase and maintenance of such equipment, as well as their importance in maintaining interior environments, undesirable changes in performance and / or damage can be very disruptive to the property.

[0023] There are a limited number of commercial systems designed to reduce the exposure of HVAC systems to environmental conditions by elevating the heavy and bulky HVAC systems off of the property grounds. Elevation may allow snow, rain, and / or debris to flow off of an HVAC system (instead of pooling at the base, causing damage such as rusting), and the be out of way for pests and animals. However, the inventor has recognized that such systems are bulky, tedious to assemble (e.g., may take a skilled technician about an hour or more to install each elevation system), and susceptible to rust and rot. For example, most existing systems are formed of a milled steel material with a thin coating, such that a small nick or scratch may quickly rust the system and increase the risk of collapse and damage to the expensive HVAC systems. Furthermore, such elevation systems are often specialized for particular HVAC systems, making it expensive and time-consuming to track down each elevation system for a number of HVAC system on the property.

[0024] In view of the foregoing, the inventor has recognized a need for a system to elevate and support HVAC systems to protect from environmental conditions. The system may accommodate a variety of commercial HVAC system sizes while being easy to assemble by an ordinary user. Furthermore, the systems may provide robust structural support even on uneven terrain, while still providing full access to the HVAC system for adjustments or monitoring. Of course, instances in which different benefits are offered by the systems and methods disclosed herein are also possible.

[0025] In some embodiments, an HVAC support system may be rapidly assembled through the use of foldable legs that can transform the support system between a relatively flat form factor to an expanded form factor capable of elevating any commercial HVAC system off the ground. Foldable legs may reduce the overall footprint of the system for storage and / or transport, while still allowing the user to quickly and efficiently assemble the system for use. In some embodiments, the support system may be assembled in under five minutes, which may represent a 90% savings in assembly time, while still resulting in a robust support system.

[0026] In some embodiments, an HVAC support system may include a substantially planar (e.g., flat) frame coupled to a number of legs (e.g., four) which may be arranged normal to the frame to help elevate an HVAC system, akin to a table. In some embodiments, the legs may be foldable between an orientation aligned with the frame (in a disassembled configuration) and an orientation normal to the frame (in an assembled configuration). As will be described in detail below, the legs may be coupled to the frame in a manner that prevents lateral movement while permitting rotational movement of the legs relative to the frame. When the legs are rotated to a desired orientation relative to the frame (e.g., normal), the legs may be locked in place, preventing any lateral or rotational movement of the legs relative to the frame. In such a configuration, the support system may be stable and rigid to support and elevate a bulky HVAC system.

[0027] In some embodiments, an HVAC support system may include two or more crossbars for interfacing with an HVAC system. The crossbars may be arranged at the topmost surface of the support system and coupled to the frame of the support system. The crossbars may include features that facilitate fastening or other attachment of the HVAC system to the crossbars for enhanced support. For example, in some instances, the HVAC system may generate vibrations during operation. The inventor has accordingly recognized that attaching the HVAC system directly to the support system (as opposed to resting the HVAC system on the support system) may enhance the supporting capability of the system while also optionally absorbing some of the vibrations, which may enhance the HVAC system’s operation.

[0028] In some embodiments, the crossbars may be adjustable to accommodate a variety of commercial HVAC systems. During assembly, a user may adjust the position of the crossbars relative to pre-existing fastener holes on the HVAC system (and / or any other desired position) and then secure the crossbars to prevent further movement of the crossbars relative to the frame.

[0029] In some embodiments, the crossbars may include a projection oriented normal to a body of the crossbars, which may help provide support for top-discharge HVAC systems (e.g., top-discharge heat pumps) while still providing a user unobstructed access to any ventilation and controls of HVAC system. The projections may abut against and fastened to a side surface of the HVAC system in a cradling fashion, maintaining the HVAC system in place. In embodiments where the support system is used with side-discharge HVAC heatpumps, a user may elect to arrange the crossbar in a manner that points the projection away from the heat pump and instead fasten the HVAC system to the body of the crossbar, as will be described in greater detail below. Thus, the support systems of the present disclosure provide sufficient variability for a user to elect the most suitable orientation for their use while still providing robust structural support and elevation.

[0030] In some embodiments, HVAC systems are arranged on uneven and unsupportive terrain, such as bumpy grass or a rocky / gravelly surface. Accordingly, the inventor has recognized the benefit of adjustable feet that may allow a user to maintain the HVAC system substantially normal to gravity (for optimized HVAC system operation) even on uneven terrain. In some embodiments, the HVAC support systems of the present disclosure may include adjustable feet optionally coupled to each of the legs. Each foot may be independently adjusted to accommodate any variations in the support surface (e.g., ground), while still providing robust structural support. In some embodiments, the feet may have a larger cross-sectional area than the legs, thus further stabilizing the system. In some embodiments, a user may elect to directly fasten the feet to the support surface for enhanced structural support.

[0031] In some embodiments, an HVAC support system may include shoes that may be removably coupled to the feet to provide additional structural support. The shoes may be formed of a compliant material (e.g., rubber), which may absorb additional vibrations from the HVAC system’s operation to further stabilize the support system. The user may elect not to use the shoes depending on the location of the HVAC system and / or any other factors.

[0032] HVAC support systems of the present disclosure may be capable of supporting the weight of any conventional HVAC system in their assembled state. For example, an assembled HVAC support system may support an HVAC system weighing up to 100 lbs, 200 lbs, 300 lbs, 400 lbs, 500 lbs, 600 lbs, 700 lbs, 800 lbs, 1000 lbs, as well as its associated vibrational loads.

[0033] The HVAC support systems of the present disclosure may be formed of any suitable environmentally resistant material. In some embodiments, the support systems may be formed of an aluminum material (e.g., 6061 aluminum) with a coating that may reduce the risk of rotting and rusting. The coating may be formed of any suitable material, such as a powder coating. For example, the support systems of the present disclosure may be at least partially coated with a polyester (e.g., triglycidyl isocyanurate) coating. In someembodiments, the various hardware (e.g., fasteners) employed with the HVAC support systems may be formed of a rust-resistant material, such as stainless steel. It should be appreciated that the material composition of the HVAC support system is non-limiting, and that alternative environmentally resistant material known in the art are also contemplated.

[0034] It should be appreciated that the support systems described herein may be used to elevate any HVAC system, including, but not limited to, air conditioners, heat pumps, furnaces, chillers, compressors, fans, cooling towers, refrigeration equipment. The support systems described herein may also be used to elevate other large equipment. Accordingly, the systems of the present disclosure are not limited to HVAC systems.

[0035] Turning to the figures, specific non-limiting embodiments are described in further detail. It should be understood that the various systems, components, features, and methods described relative to these embodiments may be used either individually and / or in any desired combination as the disclosure is not limited to only the specific embodiments described herein.

[0036] FIGs. 1A-1B show an assembled HVAC support system 100 according to some embodiments. The HVAC support system 100 may include a substantially planar frame 110 extending substantially along a plane with a series of legs 120 extending from the plane of the frame. As described above, the legs 120 may facilitate the elevation of the HVAC system away from the ground, while the frame 110 may support the HVAC system. In some embodiments, the HVAC support system 100 may optionally include feet 130 to secure the legs 120 into a support surface (e.g., ground). In embodiments where the HVAC support system 100 includes feet 130, the feet 130 may be used in conjunction with shoes 140 to further secure the system installation and absorb vibrational energy from the system. In some embodiments, the HVAC support system includes crossbars 150 that may be secured to the HVAC support system to help retain the system in place relative to the frame 110.

[0037] As shown in FIG. 1A, the assembled HVAC support system 100 may have a substantially rectangular or square footprint. In some embodiments, the support system footprint may be reduced through a disassembly process for ease of storage and reduce shipping costs, among other benefits. In some embodiments, the legs 120 of the system 100 may be rotatable about axis DI (as shown in FIG. 1A) such that they may be folded against the frame 110. As will be described in greater detail below, the legs 120 may be shipped in the folded configuration, and once at the target site, a user may rotate the legs 120 about axisDI and subsequently lock (e.g., with a fastener 125A) the legs 120 relative to the frame 110. For disassembly, the user may also disassemble the support system 100 by unlocking the legs from the frame 110 and rotating the legs 120 back to their folded configuration.

[0038] In some embodiments, the support system 100 may include two pairs of legs 120, each pair connected to one another through beams 112, as shown in FIG. 1 A. The beams 112 may be fixed to the legs, allowing the pair of legs 120 to be readily rotated without the need for individual rotation of legs. In some embodiments, the beams 112 may help maintain a constant distance between the frame members 110a, 110b. In some embodiments, the beam 112 may also ensure that each pair of legs 120 is rotated to the same position, ensuring proper support for the HVAC system. In some embodiments, the beam 112 may also serve as an additional support structure to enhance the rigidity of the system 100. Embodiments without beams, wherein the user individually rotates each of the four (or any other number of legs) legs are also contemplated, as the present disclosure is not so limited.

[0039] In some embodiments, the frame 110 may be connected to the legs 120 through a series of right-angle braces 114, as shown in FIG. 1A. In some embodiments, the braces 114 may be fixed to the frame members 110a, 110b through a number of fasteners (e.g., rivets). The fasteners may be arranged in a manner that prevents any movement (e.g., axial translation, rotation) of the frame relative to the brace. For example, as shown in FIG. 1A, the braces 114 may be secured to the frame 110 through a linear series of three rivets, fixing the frame to the braces in all directions. Of course, other means of securing the braces to the frame to prevent movement of the braces relative to the frame are also contemplated. As will be discussed in greater detail below, in some embodiments, the braces may also be fixed to the legs 120 in a manner that permits the legs 120 to rotate about axis DI during assembly. Once the legs 120 are oriented in the desired rotational position relative to the frame 110, a user may further fix the legs 120 to the braces 114 to prevent further rotation, as will be discussed in greater detail below.

[0040] In some embodiments, the crossbars 150 may be movable along axis D2 (as shown in FIG. 1 A) on the frame 110 to accommodate a variety of commercial HVAC system sizes. Once the crossbars 150 are adjusted to a desired position along the frame 110, a user may fix the crossbars 150 in place relative to the frame 110. The HVAC system may then be installed on the crossbars by passing fasteners through slots 154 arranged on the crossbars 150. In other embodiments, the HVAC system may be installed on the crossbars prior toinstallation of the crossbars on the frame 110. In some embodiments, the pre-installation of the HVAC system on the crossbars may facilitate one-person assembly of the support system. For example, the HVAC system may first be installed on the crossbars, then the crossbars may be secured to the frame while the legs are in the folded configuration, and then the user may raise each pair of legs to help raise the HVAC system. Of course, other techniques of one-person assembly are also contemplated. It should also be appreciated that the support systems described herein may be assembled by a single person even if the HVAC system is not initially installed on the crossbars. For disassembly, the crossbars may be disassociated from the HVAC system and, if necessary, the frame, and the legs may be folded for storage or transport. Accordingly, the crossbars 150 may be reversibly fixed relative to the frame 110.

[0041] It should be appreciated that although four legs 120, two beams 112, and two frame members 110a, 110b are shown in FIG. 1A, embodiments having other number of legs and frame members are also contemplated.

[0042] In some embodiments, the system 100 may be sized to accommodate a variety of commercial HVAC systems while still maintaining a manageable footprint for storage and transport. The system 100 may have an overall length LI measured between two shoes 140, as shown in FIG. IB. In some embodiments, the overall length LI may be greater than, less than, or equal to, approximately 30 inches, 35 inches, 38 inches, 40 inches, 45 inches, and / or any other suitable length. The system 100 may also be characterized by an overall width W1 measured between shoes 140, as shown in FIG. IB. In some embodiments, the overall width W1 may be greater than, less than, or equal to, approximately 20 inches, 23 inches, 25 inches, 28 inches, and / or any other suitable width.

[0043] In some embodiments, the system 100 may be characterized by a width W2 extending between inner faces of braces 114, as shown in FIG. IB. In some embodiments, width W2 may correspond to the furthest possible extents of slots 154, although other embodiments are also contemplated. In some embodiments, the width W2 may be greater than, less than, or equal to, approximately 14 inches, 16 inches, 18 inches, 20 inches, 22 inches, and / or any other suitable width.

[0044] In some embodiments, the crossbars 150 may include two slots 154, each extending from a respective distal end of the crossbar to an intermediate portion, as shown in FIG. IB. In this way, HVAC systems of various sizes may be loaded on the system 100 andmay be secured at any suitable location (e.g., at various pre-existing holes on the HVAC system designed to attach the HVAC system to a support structure). Accordingly, each slot 154 may extend along a width W3 along the crossbar 150. In some embodiments, the width W3 of the slots 154 may be greater than, less than, equal to, approximately 2 inches, 3 inches, 4 inches, 5 inches, and / or any other suitable width. In one example, the width W3 of the slots 154 is 3.94 inches. It should be appreciated that the width W3 of the slots 154 may change based on the width W1 of the system. The crossbars 150 may also be characterized by a length L2, as shown in FIG. IB. In some embodiments, length L2 of the crossbars 150 may be greater than, less than, or equal to, approximately 2 inches, 3 inches, 4 inches, 5 inches, and / or any other suitable length.

[0045] Although crossbars 150 with two slots 154 are shown in FIG. IB, embodiments with crossbars having less than and more than two slots are also contemplated. For example, a crossbar may have one singular crossbar extending along substantially the length of the crossbar. In another example, the crossbar may have a series of short slots corresponding to existing holes on commercial HVAC systems. In some embodiments, discontinuous slots may enhance the strength of the crossbars.

[0046] In some embodiments, the system 100 may include crossbars 150 that may be slidable across the frame 110 (along axis D2, as shown in FIG. 1 A) to accommodate a variety of HVAC system sizes. In some embodiments, the maximum distance between crossbars 150 may extend a length L3 between the inner edges of the braces 114, as shown in FIG. IB. In some embodiments, the length L3 may be greater than, less than, or equal to, approximately 22 inches, 25 inches, 27 inches, 30 inches, 32 inches, and / or any other suitable length.

[0047] As described previously, the HVAC support system of the present disclosure may serve to elevate an HVAC system away from a support surface (e.g., ground). In some embodiments, the support system 100 may elevate the HVAC system a height Hl away from a support surface, as shown in FIG. IB. Height Hl may correspond to an overall height of the system. In some embodiments, height Hl may be greater than, less than, or equal to, approximately 10.5 inches, 12.5 inches, 14.5 inches, 16.5 inches, 18.5 inches, 20.5 inches, 22.5 inches, and / or any other suitable height.

[0048] In some embodiments, shoes 140 of the system 100 may have a generally square-shaped form factor. Accordingly, shoes 140 may be characterized by a width W4, as shown in FIG. IB. In some embodiments, width W4 may be greater than, less than, or equalto, approximately 2 inches, 3 inches, 4 inches, 5 inches, 6 inches, and / or any other suitable width. Embodiments with non-square shaped shoes are also contemplated. In some embodiments, sizing of the shoe may be adjusted to accommodate the support surface and / or the vibrational state of the HVAC system.

[0049] It should be appreciated that the present disclosure is not limited to the aforementioned ranges and / or combinations of ranges of sizes, and that other ranges are also contemplated to accommodate a variety of HVAC system sizes.

[0050] In some embodiments, the HVAC support system may be fully disassembled for storage and / or transport purposes. FIG. 2 shows the various disassembled components of an HVAC support system 100. As discussed previously, the system 100 may include a frame 110 connected to legs 120, which may be folded into a compact configuration, as shown in FIG. 2. Folded legs 120 may serve to reduce the overall footprint of the system for storage and / or transport, while still allowing the user to quickly and efficiently assemble the system for use. In some embodiments, the system may also include a number of feet 130 which may be installed on the distal ends of the legs 120 during assembly, as well as optional shoes 140 which may be installed on the feet for improved energy absorbance and support surface contact. Optionally, in some embodiments, crossbars 150 may be removable from the frame 110. For example, the crossbars 150 may be installed on the HVAC system prior to their installation on the frame 110. Of course, embodiments in which crossbars 150 are preinstalled on the frame 110 are also contemplated, as the present disclosure is not limited to the placement of the crossbars prior to assembly.

[0051] In some embodiments, the system 100 may also include a variety of generic and specialized hardware for assembly. For example, in some embodiments, the crossbars 150 may be secured to the frame 110 with brackets 160, as will be described in greater detail below. Other generic hardware, such as conventional fasteners, may be employed to assemble the system (not shown).

[0052] FIGs. 3A-3D show a process of assembling an HVAC support system 100 according to some embodiments. The system 100 of FIGs. 3A-3D includes pre-installed crossbars 150. The system 100 may be in a generally flat and low-profile configuration in its folded configuration, as shown in FIG. 3A. A user may then rotate a first pair of legs 120A about axis DI and away from the frame 110, as shown in FIGs. 3A-3B. As discussed previously, a first pair of legs 120A may be coupled to one another through a beam 112A,such that the user may only manipulate one leg of the pair of legs to rotate the pair of legs 120A. Similarly, a second pair of legs 120B, coupled to one another through beam 112B, may be rotated and subsequently unfolded about axis DI, as shown in FIGs. 3A-3B. It should be appreciated that although the pairs of legs 120 A, 120B are shown to be rotated sequentially, a user may also elect to rotate both pairs simultaneously.

[0053] Once both pairs of legs 120A, 120B are oriented in the desired position, as shown in FIG. 3C, they may be fixed in place using fasteners 125 A, 125B. In some embodiments, fastener 125A may be a carriage bolt and fastener 125B may be a corresponding nut, which may facilitate one-handed fastening of the legs relative to the brace. In some embodiments, by tightening the fasteners 125A, 125B about legs 120 relative to braces 114, the legs 120 may be prevented from further rotation about axis DI, such that they may remain stable and support an HVAC system. In some embodiments, the fasteners 125A, 125B may be removed from the system 100 to permit the legs 120 to return to their folded configuration during a disassembly process.

[0054] It should be appreciated that although the legs may be coupled to the frame, the rotation or folding process may be readily achieved by an average user. Accordingly, the system may be assembled manually without the use of specialty tools and excess power. In this way, the system can be quickly and easily assembled to elevate an HVAC system.

[0055] In some embodiments, as shown in FIGs. 3C-3D, a user may choose to install feet 130 on the legs 120 to further stabilize the system relative to a support surface. As shown in FIG. 3C, the feet 130 may be installed on the legs 120 along an axis D3 with conventional fasteners (not shown). In some embodiments, a user may optionally choose to install shoes 140 on the feet 130 to reduce vibrational energy at the interface of the feet 130 and the support surface.

[0056] As discussed previously, the system 100 may have crossbars 150 that may be slidable along an axis D2 on frame 110 to accommodate a variety of HVAC system sizes. As shown in FIG. 3D, once the crossbars are arranged at a desired position along the frame 110, a user may secure the position of the crossbars 150 through a bracket (not shown) to prevent further lateral movement along axis D2, as will be described in greater detail below. Once the system 100 is assembled, a user may then install an HVAC system (not shown) on the crossbars 150 to help elevate and further support the HVAC system during operation.

[0057] It should be appreciated that upon completion of the assembly process (i.e., at FIG. 3D), all parts of the support system may be fixed to one another. In other words, an assembled support system may have no moving parts to further enhance the stability of the system for supporting an HVAC system. Of course, the support system may be disassembled or re-adjusted to accommodate other HVAC systems following use. However, a substantially rigid support system offers the benefit of robust support while reducing the likelihood of additional vibration associated with improper interfacial contacts (e.g., slidable crossbars, or rotatable legs).

[0058] It should also be appreciated that embodiments including only feet as well as embodiments including neither feet nor shoes are also contemplated. For example, the legs may be directly fastened into the support surface.

[0059] FIG. 4 shows an exploded view of a leg assembly according to some embodiments. In some embodiments, a leg 120 may be coupled to a brace 114 through a permanent rivet 116 which may fix the brace 114 to the leg 120. The leg 120 may therefore be free to rotate about an axis DI relative to the brace 114 due to the pin-type rivet connection. As shown in FIG. 4, axis DI is defined by the position of rivet 116 and associated hole 125D of the leg 120 (see FIG. 7 for non-exploded view). On its own, the rivet 116, coupled permanently to hole 125D of the leg, permits the leg 120 to rotate relative to the brace 114 (which may be fixed to a frame, not shown) while still being coupled to the frame (see frame 110 in FIG. 1A). This connection may serve to reduce the number of assembly steps so the user may quickly be able to assemble the system and install the HVAC system. It should be appreciated that other fasteners that permit rotation (e.g., other than rivets) may also be employed, as the present disclosure is not limited by the fastener types.

[0060] When the user has rotated the leg 120 to the desired position (e.g., normal to the frame), they may seek to releasably lock the leg 120 in place. To do so, the user may secure a fastener 125A, 125B to the leg 120 and through hole 125C of the leg 120 and hole 114C in the brace (see FIG. 7 for close-up view of the assembled brace). In some embodiments, hole 114C on brace 114 may be arranged linearly relative to the rivet 116, such that securing the leg to hole 114C may releasably prevent rotation of the leg 120 relative to the brace 114. The linear arrangement of the hole 114C relative to the rivet 116 may transform the connection between the leg and the brace from a pin-type connection (whereby rotation is permitted, but translation is not) to a fixed connection (whereby no movement ofthe leg relative to the brace is permitted). In some embodiments, the fastener 125A may be a carriage bolt with a corresponding nut, to facilitate one-handed fastening of the leg to the brace, although other fasteners are also contemplated. It should be appreciated that once the fastener 125A is removed from the leg 120, the leg may be free to rotate relative to the brace 114, permitting the user to position the leg in a folded configuration.

[0061] In some embodiments, a user may elect to install a foot 130 on a distal end 121 of the leg 120. The foot 130 may be formed of a substantially rigid material (e.g., metal) to further stabilize the system. In some embodiments, the foot 130 may have a substantially planar body 132 which may extend beyond the footprint of the leg 120. The extended footprint of the foot may help further stabilize and secure the system relative to the support surface (e.g., ground). The foot body 132 may have one or more opening 134 to allow a fastener 50 to secure the foot to the distal end 121 of the leg, as shown in the exploded view of FIG. 4.

[0062] In some embodiments, fastener 50 may also serve the function of adjusting the total height (along axis HH in FIG. 4) of the leg and foot assembly to accommodate uneven terrain. In other words, a user may desire to keep the support system substantially normal relative to gravity (for optimized HVAC operation) even on uneven terrain. The fastener 50 may be a threaded rod, such as a leveling screw, which may retain a robust connection between the leg and the foot at a variety of heights. It should be appreciated that the fastener 50 may be adjustable along axis HH but still sufficiently coupled to the feet to reduce the risk of unwanted height-wise translation due to vibration of the HVAC system during operation. For example, a user may choose to adjust the height of the foot of one of the legs to accommodate a depression on the support surface. Each of the feet may be independently adjusted to ensure a sturdy support for the HVAC system. It should be appreciated that although leveling screws are shown in FIG. 4, other methods of controllably adjusting the height of the leg and foot assemblies are also contemplated.

[0063] In some embodiments, the foot body 132 may have one or more holes 136 to permit a user to secure the foot 130 to the support surface through fasteners (not shown). It should be appreciated that embodiments in which the system simply rests on the support surface and is not necessarily secured to the support surface are also contemplated.

[0064] As shown in FIG. 4, in some embodiments, a shoe 140 may be installed about the foot 130 to provide additional energy absorption support to the system during operation.The shoe 140 may be formed of a compliant material (e.g., high durability rubber). Thus, the shoe may be flexible to snap on to the feet 130 during assembly and snap off of the feet 130 during disassembly. In some embodiments, the foot 130 may form reversible interference fits with the shoe 140. It should be appreciated that feet with a permanently connected shoes are also contemplated.

[0065] In some embodiments, the shoe 140 may have a generally frame-like shape, as shown in FIG. 4. The shoe 140 may have a frame 142 with an inner opening 141. In some embodiments, the inner opening may allow a fastener 50 to pass through and secure the foot 130 to the leg 120. The shoe 140 may also include a series of tabs 144 which may serve to secure the frame 142 to the foot 130 and prevent dislodgement. The tabs 144 may prevent axial motion of the foot body 132 relative to the shoe 140. In some embodiments, the frame 142 may include a series of holes 146 which may be aligned with the holes 136 of the foot 130 following assembly. The holes 136, 146 may permit a user to fasten the foot and shoe assembly to the support surface by threading fasteners (not shown) through the holes and into the support surface. As discussed earlier, embodiments in which the system is not secured to the support surface are also contemplated.

[0066] FIG. 5 shows a perspective sectional view of an installed shoe and foot assembly across line 5-5 of FIG. 1 A. The leg of the HVAC support system is not shown in FIG. 5 for visual clarity. As shown in FIG. 5, when a shoe 140 is installed on a foot 130, a frame 142 of the shoe 140 may surrounded the generally planar body of the foot 130. In some embodiments, the shoe 140 may include tabs 144 that may overlie the body of the foot and prevent axial movement of the foot 130 relative to the shoe. In some embodiments, a fastener system 51 may pass through an opening 134 of the foot 130 and an opening of the shoe (see opening 141 in FIG. 4) to help secure the foot 130 to the leg (not shown). As described earlier, the foot 130 may be removably coupled to the shoe 140 through one or more interference fits. The foot 130 may also optionally be secured to a support surface. In this way, the foot may serve to further stabilize the HVAC support system while the shoe may serve to further stabilize and reduce vibrational energy from the system.

[0067] FIG. 6 shows a close-up view of detail 6 of FIG. 5 with the foot removed for visual clarity. As shown in FIG. 6, a foot may be secured between a ledge 145 of a tab 144 of the shoe and a frame ledge 148 of the shoe frame 142. The shoe 140 may be formed of a compliant material, permitting the user to snap a foot into the shoe and arranged in thesecured position. For example, the tabs 144 of the shoe, which may be arranged in a cantilevered fashion, may be able to move out of the way to permit the user to position the foot within the shoe. Thus, in some embodiments, a user may be able to install a shoe on a foot without the use of fasteners, improving the assembly and disassembly process efficiencies.

[0068] FIG. 7 shows a close-up view of detail 7 of FIG. 1A, showing an assembled HVAC support system. As shown in FIG. 7, during assembly, the legs 120 may be secured to the brace 114 through fasteners 125A, 125B, preventing further rotation of the legs relative to the braces 114. To disassemble, the fasteners 125A, 125B may be removed from the legs 120 and brace 114, permitting the legs 120 to rotate relative to the brace 114 about axis DI. In some embodiments, the legs 120 may be laterally fixed to the braces 114 through rivets 116. The rivets 116 may help retain the legs laterally relative to the frame 110, while still permitting the legs to rotate about axis DI. As described previously, once the fasteners 125A, 125B are installed on the legs 120 and braces 114, the legs 120 may be both laterally and rotationally fixed to the frame 110. As shown in FIG. 7, the braces 114 may be rotationally and laterally fixed to the frame 110 due to an arrangement of a row of rivets. It should be appreciated that although rivets are described herein, other conventional fasteners may be employed.

[0069] FIG. 8 shows an exploded close-up view of detail 8 from FIG. 3D, illustrating a method of securing a crossbar 150 to a frame 110 of a HVAC support system. In some embodiments, a crossbar 150 may be secured to a frame 110 using a bracket 160. The bracket 160 may have a substantially U-shaped form factor, with a central bend 162 and a distal tab 161. The central bend 162 may be shaped and sized to wrap around multiple faces of a frame 110, as shown in FIG. 8. The bracket 160 may also include a hole 164 which may be aligned with a hole 151 of the crossbar 150 during assembly. In some embodiments, hole 151 of the crossbar may be positioned on a crossbar tab 152, shaped to extend along a top surface of the frame 110 (see also FIG. 1A). Once holes 151, 164 are aligned, a fastener 50 may pass through holes 151, 164 to secure the bracket 160 to the crossbar 150. The central bend 162 of the bracket 160 may transfer the locking force of the fastener around the frame 110, such that securing a fastener through holes 151, 164 may not only secure the bracket 160 to the crossbar 150, but also the bracket 160 to the frame 110. In some embodiments, the central bend 162 may apply frictional forces to the frame 110 to help secure the assembly.

[0070] In some embodiments, the crossbar 150 may have a projection 156, as shown in FIG. 8. The projection 156 may extend substantially normal from a crossbar body 157. In some embodiments, the projection 156 may include a gap 158, which may permit the tab 152 of the crossbar 150 to extend over the frame 110. In this way, the bracket 160 and tab 152 together may wrap around the frame 110 and help secure the assembly and prevent lateral translation of the crossbar 150.

[0071] In some embodiments, crossbars may be preloaded on the frame prior to assembly. In such embodiments, the brackets may not be fully fixed to the crossbars, permitting a user to laterally move the crossbars across the frame, while still retaining the crossbars in place within the general footprint of the frame. In this way, a user may adjust the crossbars to accommodate an HVAC system without having to assemble each bracket. The user may adjust the position of the crossbars by sliding each crossbar along the frame to reach a desired position. In embodiments where the crossbars are preloaded on the frame, the brackets may be loosely coupled to the crossbars, such that the brackets may move with the crossbars across the frame. When the crossbars are arranged in a desired position, the user may tighten the fasteners (see fastener 50 in FIG. 8) pre-loaded on the bracket to prevent lateral translation of the crossbars and brackets. Pre-loaded brackets may expedite the assembly process. It should be appreciated that regardless of the state of the brackets prior to assembly, the brackets may be removably attached to the frame. In some embodiments, the crossbars may not be pre-loaded on the frame prior to assembly, which may allow a user to install the crossbars on the HVAC system prior to installing the crossbars on the frame. In any case, the user may choose the most efficient path for installation.

[0072] FIG. 9 shows an assembled support system 100 supporting an HVAC system 200 according to some embodiments. As shown in FIG. 9, the support system may have locked legs 120 arranged normal to a frame 110. The height of the legs 120 may serve to elevate the HVAC system 200 off of a support a distance equivalent to the height of the system (see FIG. IB). In some embodiments, the system 200 may be secured through one or more fasteners passed through slots (see slots 154 in FIG. 1A) of the crossbars 150 to fix the HVAC system to the crossbars 150. In its assembled form, the crossbars 150 may be reversibly fixed to the frame 110, helping retain the HVAC system in place relative to the remainder of the support system 100.

[0073] The HVAC system 200 in FIG. 9 represents a side-discharge heat pump. By securing the HVAC system 200 to the crossbars 150 through its bottom face, the support systems of the present disclosure may not block any sidewalls of the HVAC system, as shown in FIG. 9. Accordingly, a user may be able to access any side of the HVAC system during operation for controlling and monitoring the HVAC system. Thus, the support system may serve to securely retain the HVAC system in place without significant obstruction of access.

[0074] In some embodiments, a user may desire to elevate and support a topdischarge HVAC system. In such embodiments, the support system may include reversible crossbars, such that when the crossbar is inverted, the projection may be pointed away from the support surface, as shown in FIGs. 10A-10B. In such embodiments, the projections 156 may abut against a side surface of an HVAC system (e.g., top-discharge heat pump) to secure the HVAC system to the support system. In some embodiments, the sidewalls of the HVAC systems may be fixed to the projections 156. For example, as shown in FIGs. 10A-10B, fasteners may be secured through holes 155 to help secure and fix the HVAC system to the crossbars. Optionally, the HVAC system may also be secured on their lower surfaces by securing fasteners through slots 154 of the crossbars. In some embodiments, the HVAC system may simply rest on the body (see crossbar body 157 in FIG. 8) without the need to secure fasteners through slots 154. FIG. 10B shows another embodiment of the HVAC support system in which the crossbar body is not positioned underneath the HVAC system. Although the crossbar bodies play a role in supporting the weight of the HVAC systems, such an arrangement may be suitable for users who require full access to the bottom of the HVAC system. It should be appreciated that given the number of ways the support system may be arranged, a user may assemble the HVAC system according to a desired level of structural security and HVAC system type (and related operation).

[0075] In some embodiments, the system may employ the use of energy absorption pads to further reduce the vibrational load of the HVAC system on the support system. For example, as shown in FIG. 11, an energy absorption pad 180 may be arranged on a crossbar 150 body 157 in a manner that may reduce the vibrations generated by the HVAC system. In this way, the system may be further stabilized to provide long term support for the HVAC system. It should be appreciated that in some embodiments, the energy absorption pads may be arranged at an interface between the HVAC system and the crossbar 150, as shown in FIG.11, whereas in other embodiments, the energy absorption pads may be arranged in other locations on the system. It should also be appreciated that the shape of the energy absorption pad is not limited to that shown in FIG. 11. Accordingly, the energy absorption pad 180 shown in FIG. 11 is non-limiting in both structure, position, and shape.
