WHAT IS CLAIMED

1. An apparatus for mounting a piece of equipment above a roof, the apparatus comprising: a pedestal (10) having a top wall surface (11), a bottom wall (21) surface, and sidewall (31) surfaces extending an entire distance between the top (11) and bottom (21) wall surfaces, the sidewall (31) surfaces including at least one angled portion (35); a plurality of rails (23) extending along and outward of the bottom wall (21) surface, the rails (23) including a flange (27) at a lower end (29) and forming a channel (25) between adjacent rails (23), an upper end (29) of each channel (25) being closed by the bottom wall (21) surface, a lower end (28) of the each channel (25) being open; a plurality of rails (13) extending along and inward of the top wall (11) surface, the rails (13) including a flange (17) at an upper end (18) forming a portion of the top wall (11) surface and forming a channel (15) between adjacent rails (13), an upper end (18) of each channel (15) being open, and a lower end (19) being closed; wherein no mechanical fasteners are needed to secure the pedestal to the roof.

Description:
ROOF-MOUNTED EQUIPMENT ATTACHMENT SYSTEM

BACKGROUND

This disclosure relates generally to attachment systems for roof-mounted products such as, but not limited to, solar panels and HVAC equipment. More specifically, the disclosure addresses attachment systems that do not penetrate the roof decking with mechanical fasteners and are well-suited to meet or exceed building codes designed to prevent or minimize roof damage due to high winds (e.g. Dade County, FL building code).

SUMMARY

Embodiments of an attachment system or mounting pedestal of this disclosure include a longitudinally extending rigid member with angled sidewalls, an optional central passageway, and a plurality of channels or rails, a lower set of channels or rails extend below the bottom wall surface and an upper set of channels or rails are recessed from the top wall surface. The channels or rails may extend an entire length of the rigid member. In some embodiments, the number of lower channels is greater than that of the upper channels. The lower set of channels may have a same width and depth as one another and the upper set of channels may differ in width and depth from one another. A center channel of the upper set may be sized to receive the head of a bolt or fastener for connection to the equipment. The lower set of channels or rails provide spacing and depth so that an adequate amount of foam adhesive resides between the bottom wall surface and the roof deck. The rails provide a flange that provides additional surface area for bonding to the adhesive. As the foam adhesive expands it surrounds the rails and enters the channels. Once the adhesive cures, the rigid member is securely affixed to the roof without the need for mechanical fasteners to penetrate the roof decking.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front (or rear) elevation view of an embodiment of a standard (non-angled top wall surface) mount of this disclosure. The left and right side elevation views are mirrors of one another.

FIG. 2 is an isometric view of the mount of FIG. 1. The lower set of channels or rails extend an entire length of the mount, as does the upper set of channels or rails. FIG. 3 is an isometric view of an embodiment of a profiled (5° angled top wall surface) mount of this disclosure. In embodiments, the angle may be in a range of 5° to 15° with the left and right sides differing in height accordingly. The front and rear elevation views are mirrors of one another. The lower set of channels or rails extend an entire length of the mount, as does the upper set of channels or rails. FIG. 4 is an isometric view of a profiled mount of this disclosure having a greater height than that of the mount of FIG. 3. The width, length, and height of the mount may be any width, length, and height suitable to safely support the piece of equipment to be mounted and provide an appropriate amount of clearance between the bottom end of the equipment and the roof.

DETAILED DESCRIPTION

Referring to the drawings, an attachment system or mounting pedestal of this disclosure includes a longitudinally extending rigid member 10 having a top wall 11, a bottom wall 21, and side walls 31 including an upper and a lower straight wall portion 33, 37 and an angled portion 35 located in between. The walls 11, 21, 31 may form a central passageway 41 extending the length of the rigid member 10 and used to house wiring, cabling, or insulation. The rigid member 10 may an extruded polymer member or a metal member.

The bottom wall surface 21 provides a solid wall surface from which a set of rails 23 extend to form channels 25 between adjacent rails 23. This set of rails 23 and channels 25 may extend an entire length of the rigid member 10. Flanges 27 located at the lower end 29 of the rail 23 provide feet or additional surface area to contact foam adhesive used to mount the member 10 to the roof. The upper end 29 of the channel 25 is closed by the bottom wall 21. The lower end 28 of the channel is an open end. The channels 25 may be of uniform or differing width and depth.

Another set of rails 13 and channels 15 are located along the top wall 11, with the channels 15 being recessed from the top wall surface 11. Flanges 17 at the upper end 18 of the rails 13 form a part of the top wall surface 11. This set of rails 13 and channels 15 also may extend an entire length of the rigid member 10. The lower end 19 of the channel 15 is closed, the upper end 18 is open, flush with the top wall surface 11. The channels 15 may be of uniform or differing width and depth. One of the channels 15 may be sized to receive a fastener of a piece of equipment to be mounted to the top wall.

In embodiments, the top wall 11 may be a horizontal top wall, arranged at 90° to each upper end 39 of each sidewall 31. In other embodiments, the top wall 11 may be arranged at an angle to the sidewalls 31. The angle may be in a range of 5° to 15° with the left and right sides 31 differing in height accordingly.

While embodiments of this disclosure have been described with a certain degree of particularity, many changes may be made in the details of construction and the arrangement of components without departing from the spirit and scope of this disclosure. A system and method of this disclosure, therefore, is limited only by the scope of the attached claims, including the full range of equivalency to which each element thereof is entitled.
