Description

STRUCTURE FOR HIDING HVAC AND OTHER ROOFTOP MECHANICAL EQUIPMENT
BACKGROUND OF THE INVENTION
1. Field of the Invention [1] The present invention relates generally to structures and construction but more particularly to a structure for hiding HVAC and other rooftop mechanical equipment.

2. Description of Related Art [2] On large commercial buildings HVAC and related mechanical equipment can be found on the roof. In some instances, during the design phase, architects may incorporate some decorative elements designed for hiding such equipment from view. Recently, some municipalities have amended their building codes so that it makes it mandatory for buildings to hide such equipment. This new rule applies to new and existing buildings when renovations are done involving the roof and the mechanical equipment. In both cases, installing a structure for hiding rooftop mechanical equipment is not always an easy task. First, trying to install a new structure on a rooftop without adversely affecting the roof surface is a challenge, as one does not want a leaky roof. Also, a roof is not always level because rainwater drainage requires a slope, which adds a level of difficulty when trying to build a level structure. The added structure must not be too heavy so as to add weight beyond what the building was designed for. The mechanical equipment should not bear the load of the structure. Also, for practical reasons, the new structure must not impede the ingress and egress of air flow in and around the equipment. Finally, special openings and access ways must be provided so that maintenance can be done unimpeded by accessing the equipment from the outside as well as getting inside the structure so as to also be able to walk around and service various parts of the equipment.
No adaptive structural system that can provide such features exists. Consequently, there is therefore room for improvement in that area.

and, each bottom retaining member including a webbing section extending integrally from a base portion of the bottom retaining member, wherein the webbing section is mechanically fastened to a bottom portion of the rooftop equipment providing structural support to the structure.
[4] In one embodiment, wherein the plurality of pre-cut, adjustable metallic frame and support members are extruded or cold formed from a selected metallic material in a shape selected from the group consisting of: square, rectangular, or "C" shaped. In another embodiment, a plurality of upper connectors connected to a top section of the rooftop equipment by way of the ceiling support members is provided. In one embodiment, the ceiling support members are extendible in length via extensions, wherein the extensions are configured and sized to slide and engage with the ceiling support members.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[12] The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out their invention.
Various modifications, however, will remain readily apparent to those skilled in the art, since the general principles of the present invention have been defined herein to specifically provide a structure for hiding HVAC and other rooftop mechanical equipment.
[13] Referring now to any of the accompanying FIGS. 1-5, a structure 10 for hiding HVAC 12 and other rooftop mechanical equipment is illustrated. In one embodiment, the structure comprises a plurality of vertical support members 14, vertical frame members 16, horizontal frame members 18, ceiling support members 20, and bottom retaining members 22. In a preferred embodiment, the frame and support members previously mentioned are pre-cut, adjustable, and constructed from a metallic material, such as aluminum, galvanized steel, or any other suitable material.
The frame and support members are extruded or cold formed from the selected material in a shape such as, square, rectangular, or "C" shaped.
[14] In one embodiment, the frame and support members are size, shaped, and joined such that the HVAC and rooftop mechanical equipment is surrounded, yet still providing access around the equipment such that maintenance workers can perform any necessary maintained on the equipment when needed. The challenge with this type of design is that generally, structures of this type would

- 5 -require diagonal braces for structural strength. However, diagonal braces would block the necessary access way around the equipment. The provided access and unencumbered passageway around the equipment is a particular advantage of the present invention. To provide the necessary structure and support, webbing sections 34 are provided, wherein the webbing section extend integrally from base portion 36 of bottom retaining members 22. In one embodiment, the webbing sections are mechanically fastened to a bottom portion 17 of the rooftop mechanical equipment. Further, upper connectors 38 are connected to a top section 19 of the rooftop mechanical equipment by way of ceiling support members 20.
[15] In one embodiment, the ceiling support members are extendible in length via extension 24, which are configured and sized to slide and engage with the ceiling support members. In one embodiment, the extension may be locked in place with pins, nuts, bolts, or similar fasteners via openings 26. The aligned openings are provided in rows on both the extensions and ceiling support members. The base portion and ceiling support members connect with the vertical support members as illustrated. In one embodiment, the ceiling support members connect to other ceiling support members via connecting brackets 32. In one embodiment, the vertical support members rest on pancakes 28 configured for spreading the load to eliminate potential roof damage.
[16] In one embodiment, hooks 32 are provided on the vertical support members and vertical frame members enabling the installation of a screen 30 (best seen in FIG. 2), wherein the screen provides a means for hiding the HVAC and mechanical roof equipment. Latches (not illustrated) may be provided on the screen to engage with the hooks.
[17] In a preferred embodiment, the structure is not secured directly to the roof, but rather by utilizing the existing roof equipment. In this manner, no drilling into the roof is required. Specifically,

- 6 -the roof equipment is installed on a raised platform 21, wherein holes are drilled into the bottom portion 17 of the roof equipment (best seen in FIG. 5B). This method comprises steps (a) drilling holes through a bottom portion 17 of the roof mechanical equipment; (b) inserting threaded inserts 42 into the drilled holes; (c) squeezing the threaded inserts so that they bulge in such a way that they cannot be pulled out from the bottom portion; (d) testing the strength of the insertion by partially screwing in a bolt 44 so as to let room for hooking the head of the bolt with a rod member 46 forming part of a lever 50; and (e) hooking a hanging weighing scale 48 at a distal end of the lever, and using a fulcrum part 52 of the lever pressed against the bottom portion, pulling on the lever so as to exert a pre-determined pulling force on the bolt, as measured by the scale, a way of testing the quality of the insertion of the threaded insert into the bottom portion.
[18] This validation ensures that the bottom frame of the mechanical equipment can bear any environmental load, such as wind applied to the structure. If the test is successful, bolt 44 is removed and bottom retaining member 22 is installed and the bolt with a washer is bolted in. Once the bottom retaining member is installed, the rest of the structure may be assembled.
