Description
- This application is a Continuation application, under 35 U.S.C. 120, of Ser. No. 14/482,471, filed Sep. 10, 2014, which is a Continuation of Ser. No. 13/771,746, filed Feb. 20, 2013, now U.S. Pat. No. 8,833,009, which is a Continuation of Ser. No. 12/932,892, filed Mar. 8, 2011, now U.S. Pat. No. 8,438,798, which is a Continuation-In-Part of Ser. No. 12/572,176, filed Oct. 1, 2009, now abandoned, which is a Non-Provisional patent application of U.S. Provisional Patent Application Ser. No. 61/102,333, filed Oct. 2, 2008, the complete disclosure of each of which is incorporated herein, in its entirety.
- The field of the invention is skylights systems.
- Various systems are known for using curb construction for inserting skylights and smoke vents into roofs.
- The most commonly used skylighting systems are those that incorporate translucent or transparent layers in a framework that penetrates the roof structure, so as to allow ambient daylight into the building.
- In the past, roof penetrating installations have required a complex structure beneath the roofing panels in order to support a roof curb to which the skylight was attached. Skylight curbs are generally in the form of a preassembled box structure, that is fixed within a roof cutout. The retrofitting of such curb systems into existing roof structure is problematic.
- U.S. Pat. No. 4,296,581, to Heckelsberg, issued Oct. 27, 1981, provides an example of a roofing structure of the type that is constructed of a series of metal panels having flanges that interlock when the panels are laid side by side and which are subsequently tightly seamed together to convert the individual panels into an integrated roof forming membrane. This roof structure is mounted to the purlins with clips that permit the panels to expand or contract in response to temperature and pressure changes, thereby minimizing roof stressing.
- U.S. Pat. No. 4,703,596, to Sandow, issued Nov. 3, 1987, and titled “Grid Skylight System”, provides a grid skylight support apparatus that includes prefabricated grid row frames, each of which form a number of connected beam supports which define a number of bays. Each bay has a skylight curb formed by upper flanges of the beam supports to receive a preassembled skylight unit. The sides of each grid row frame provide a mating edge that can register with the mating edge of an adjacent grid row frame during assembly. The skylights have peripheral support skirts that register upon each bay and a light-transmitting skylight panel to cover the peripheral support. Cross gutters on each grid row frame, which are positioned between adjacent skylights, extend at an angle toward the mating edge of the grid row frame for carrying rainwater to a main gutter channel formed by field-assembly of the mating edges of two adjacent grid row frames. The main gutter channel includes a pair of longitudinally extending gutter sections, each of which have a main gutter channel surface with a lower elevation than the elevation of the cross flow channel. Fasteners assemble the grid row frame mating edges together and form a continuous seal to prevent rainwater leakage at the mating edges of adjacent grid row frames.
- U.S. Pat. No. 4,520,604, to Halsey et al., issued Jun. 4, 1985, entitled “Skylight Structure”, teaches a curb structure that is dimensioned to be passed through an opening in a roof and then attached in moisture impervious relation to the roof from within a building interior. A skylight assembly including a frame and light transmitting member secured to the frame is dimensioned to be passed through the opening and attached in a sealing engagement to the curb structure from within the building interior for covering the opening. The skylight assembly is then secured to the rafters and headers at an interior location. The frame includes upper and lower clamping jaws and spaced fulcrum links attached to the jaws for clamping the light transmitting member thereto. The lower clamping jaw includes a channel which engages and is interlocked with the curb structure.
- Other skylight systems, as contemplated in U.S. Pat. No. 4,470,230, by Weisner, provide a prefabricated skylight support curb that is formed to be a protective packaging for the skylight during shipment and then used as a curb for mounting the skylight on a roof. A prefabricated skylight support curb for supporting a skylight thereover has a bottom flange angled, upright sides, and a top lip round the top of the sides forming an opening through the curb. A skylight is adapted to cover the opening through the skylight support curb when installed, and has a domed portion and an angled portion extending from the dome portion and a drip edge on the curb portion.
- In another skylight system, as contemplated in U.S. Pat. No. 3,791,088, by Sandow, et al., a prefabricated multiple dome unit or skylights and composite is provided, wherein each multiple dome unit has several domes of transparent or translucent material mounted together on a common frame, and wherein means are provided for assembling a plurality of such dome units into a composite thereof on a building, with the units lapped and interfitted so as to provide a continuous drainage system discharging to the exterior of the units in the composite assembly.
- In yet another skylight system, as contemplated in U.S. Pat. No. 4,621,466, by Sonneborn et al., a flashing frame is described for roof windows to be installed adjacent to each other with edges facing each other in the installed position with a connecting flange of its upper flashing members extending beneath the roofing and, if need be, with its lower flashing members and required intermediary flashing members, obliquely outwardly bent connecting webs and each with a connecting bar with supporting webs which rearwardly engage the connecting webs.
- In today's world of mandated energy efficiency in all types of buildings, the metal building industry needs a more economical and less detrimental way to use skylights and smoke vents to daylight their buildings. To ensure adequate daylighting, however, typical skylight and smoke vent installations require multiple roof penetrations that cut through and remove plural major elevations in standing seam and other roof panel profiles. These curbs create multiple opportunities for water to enter the interior of the building, due to multiple curb locations and the width of the curbs, as well as the challenge to effectively seal the roof at the high ends of such curbs.
- The traditional curb constructions and methods of attachment in most cases require a complicated support structure to be installed below the roof panel which can restrict movement associated with the thermal expansion and contraction of the metal roof due to temperature changes and the like.
- The invention provides a curbless construction system for installing two or more adjacent skylights and smoke vents end to end onto the major rib elevation of a building's metal panel roof system. Numerous roof structures include such elevations, sometimes deemed “ribs” or “corrugations”, including the standing seam, snap seam and “R” panel roof types. The rail and closure system is fastened to the metal roof panels along the rib structures, so that the system can move with the expansion and contraction of the roof.
- The invention utilizes elements of the roof surface structure as an integral part of the skylight support structure. In the preferred embodiment, the system includes a rail and closure structure adapted to be supported on a major rib elevation a metal roof, typically where a rib elevation has been cut to accommodate drainage. The balance of the rib is to provide structural support for the rail and closure structures.
- The invention includes a skylight adapted to be supported on the rail and closure structure, and a bearing plate structure for supporting and sealing the portion of the metal roof panel where the rib elevations have been cut away, thus preventing water accumulation at the upper surfaces of the roof panels, thereby preventing water ingress into the building.
- In some embodiments, the invention provides a skylight system (including smoke vents) where the bearing plate structure cooperates with the rail and closure assembly to close the cut away portion to water ingress.
- In another embodiment, the invention provides a rail and closure structure where the rib has been cut in only one location.
- In a further embodiment, the invention provides a rail and closure structure where the standing seam roof has trapezoidal rib elevations.
- In another embodiment, the invention provides a rail and closure structure where the metal roof is an exposed fastener roof system.
- In another embodiment, the invention provides a rail and closure structure where ribs have been cut in two locations.
- In another embodiment, the invention provides a rail and closure structure having a trapezoidal or
rectangular rib elevation 8″ to 12″ on center. - In another embodiment, the invention provides a rail and closure structure where the exposed fastener roof is of the type having roof panels fastened directly to the roof purlins from the top side of the roof panel.
- In another embodiment, the invention provides a rail and closure structure where the system comprises two or more skylights supported end to end.
- In another embodiment, the invention provides a rail and closure structure where each of the skylights is about 10 feet in length.
- In another embodiment, the invention provides a rail and closure structure where the rail and closure assembly moves with the rib elevations.
- In another embodiment, the invention provides a rail and closure structure further comprising a ridge cap configured to fit over the rib elevations at the ridge of the roof.
- In another embodiment, the invention provides a rail and closure structure where a lower closure of the rail and closure structure extends across the top of the metal roof panel profile.
- In another embodiment, the invention provides a rail and closure structure where the lower closure is configured to match the roof panel surface adjacent rib elevations for sealing.
- In another embodiment, the invention provides a rail and closure structure where the lower closure is pre-cut to match the roof surface and adjacent rib elevations for sealing.
- In another embodiment, the invention provides a rail and closure structure where the rail and closure structure is fastened directly to the rib elevations using screws or rivets.
- In another embodiment, the invention provides a rail and closure structure where the rail and closure structure forms a water tight seal with a respective rib elevation.
- In a still further embodiment, the invention provides a rail and closure structure where a portion of only one adjacent rib elevation is cut away to accommodate drainage along the roof surface.
- In another embodiment, the invention provides a rail and closure structure where portions of two or more adjacent rib elevations are cut away to accommodate drainage along the roof surface.
- These and other features and advantages of this invention are described in, or are apparent from, the following detailed description of various exemplary embodiments of the apparatus and methods according to this invention.
- A more complete understanding of the present invention and the attendant features and advantages thereof may be had by reference to the following detailed description when considered in combination with the accompanying drawings.

FIG. 16 is a perspective and partially cut away view showing a connection of adjacent skylights of the system. -
FIG. 17 shows detail of how the batten connects adjacent skylights and prevents water ingress between them. - The products and methods of the present invention provide a rail and closure structure for use in installing various roof penetrating structures in metal panel roofs. For purposes of simplicity, “roof penetrating structures” and “skylights” will be used interchangeably to mean various forms of roof structures installed for passage of light and/or ventilation to the interior of the building. In the case of roof ventilation, examples include simple ventilation openings, such as for roof fans, and smoke vents, which are used to allow the escape of smoke through the roof during fires.
- The number of skylights can vary from one to many structures connecting end to end, limited only by the amount of support provided by the roof structure, which roof structure is left largely intact during the skylight installation process.
- The system utilizes the major rib structure in the roof as the primary structure supporting the skylight assembly. Typical conventional skylight installations do not allow for continuous runs, but rather use a curb construction that is typically 2-3 times wider than the present system.
- The present rail and closure structure does not require a complex structure underneath the roof panels, nor does it require a separate curb construction to support or attach the skylight. The rail and closure structure is overlaid onto the roof system and allows for thermal expansion and contraction of the rail and closure structure by utilizing the major profiles of the metal panel roof for support. This is accomplished through direct attachment of the rail and closure structure to the major roof panel ribs.
- In reference now to the figures, the system allows the installation of two or more adjacent skylights in an end to end fashion along the major rib structure of a building's metal roof panel profile.
- The rail and closure structure can be applied to various types of ribbed roof profiles.
FIG. 1 shows the roof profile of a metal panel roof of the type known as the standingseam roof 10. The “standing seam” roof has trapezoidalmajor ribs 12 typically 24″ to 30″ on center. Eachpanel 10 will also include the panel flat 14, having ashoulder 16 and seamed at adjacent panels forming astanding seam 18, which is folded over and seamed to prevent water from penetrating the roof. -
FIG. 2 is a view showing the roof profile of a metal roof of the type known as an architectural standing seam roof, produced of a series of overlapping architecturalstanding seam panels 20. Eachpanel 20 comprises a panel flat 24, with anarchitectural standing seam 28 formed at the interconnecting panels. -
FIG. 3 is a view showing the roof profile of a metal roof of the type commonly referred to as an R panel or exposedfastener panel 30, with each panel having arib 32, and panel flat 34. Adjacent R panels are secured to the roof throughstructural fasteners 35 in the panel flat,adjacent shoulder 36. The rib is formed from overlapping regions, orside laps 38, with the adjacent panels secured to each other bystitch fasteners 39. The trapezoidal major ribs of the R panel roof are most typically formed at 8″ to 12″ on center. -
FIG. 4 is a view showing the roof profile of a metal roof of the type commonly referred to as a snap ribseam panel roof 40. A snapseam panel roof 40 haspanel flats 44 and standing seams or snapseams 48 at adjacent panels. -
FIG. 5 is a view showing the roof profile of a metal panel roof of the type commonly known as foam core panel 50, which has arib 52, aliner panel 53, a panel flat 54 and a foam core 57. Side laps 58 are secured by a stitch fastener 59. - The system of the invention includes a rail and closure structure adapted to be supported on the major elevations, seams, rib structures, or other structural elements of such roof profiles, where the standing structure provides the support, and the skylight or other load is secured over an opening formed in the intervening, non-structural roof flat region.
- Turning now to
FIG. 6 , there is shown an exemplified rail andclosure assembly 100 adapted for attachment to a standingseam panel roof 110. While the following figures depict such an assembly, it will be understood that the components could easily be adapted, by shaping of the elements, for attachments to any roof system that has a profile with elevations providing a place for structural support. - Looking again to the figures, particularly
FIGS. 6 and 7 , there is shown such a standingseam panel roof 110 having structural and other elements including a raisedrib 112, a panel flat 114,shoulder 116 and standingseam 118. Also depicted are theridge cap 120 of the roof structure, and cutaway regions, orgaps 122 formed to accommodate the structure, as described more fully as follows. - Shown as part of the system, and exemplified in this case, is a
skylight 130, generally comprising askylight frame 132 andskylight lens 134. While the figures depict a skylight, it will be understood that the system could also be adapted for use with any number of roof penetrating structures, from various types of skylights to smoke vents or other ventilating structures, which can all be adapted to be supported on the rail and closure structure system. - Again in reference to
FIGS. 6 and 7 , the system includes rail andclosure structure 140, generally comprised ofside rails upper diverter 146 disposed at the rib cutaway section orgap 122, and alower closure 150. Atgap 122, aplate 148 is located under thegap 122 to prevent water leakage into the underlying building. In assembling the rail and closure structure to a roof,plate 148 is sealed and fastened securely to the roof panel supports. -
FIG. 7 shows how thegap 122 in theroof rib 112 allowswater flow 200 along the roof surface, overplate 148, and down and away from theroof ridge cap 120. -
Lower closure 150 seals the lower end of the system from the elements. - In reference now to
FIG. 8 , there is shown a cross section through theskylight 130 region of the rail andclosure assembly 100, showing the securement of theassembly 100 to the standingseam panel roof 110. In particular,FIG. 8 depicts the use of theribs 112 to support the side rails 142 and 144. Eachrail surface 240 and arail shoulder 242. Therail skylight frame 132 by a plurality offasteners 300. - The
rail shoulder 242 is shaped to fit closely over the outside of theroof rib 112, and is secured toroof rib 112 by a plurality ofrivets 310.Upper flanges 240 of the rails support theskylight frame 132. Asealant 330 can be applied to the upper flange to seal against the passage of water or air. - It can be seen that the rail and
closure structure 140 of theassembly 100 can be produced to fit closely along the contour of theroof 110, and can be so configured to have end portions that match the contour of theribs 112. The various mating surfaces of thestructure 140 and theroof 110 can be sealed in various ways known to the roofing art, including caulking or tape mastic, or various rubber fittings or inserts can be used to seal any open areas of the roof panels. - In
FIG. 9 a partially cut away perspective view of the rail andclosure assembly 100 is used to show the support of the rail and closure system by the standingseam panel roof 110, particularly theelevated rib 112 providing the structural support.FIG. 9 shows how the rail and closure structure incorporates the structural profile of the metal roof panels, including the elevations and ribs used in sealing adjacent panels, to provide the support of skylights. In this fashion, the system adopts various advantages of a standing seam roof. - Most standing seam roofs are seamed using various clip assemblies that allow the roof to float, along the major elevation. Typically, the roof is fixed at the cave and allowed to expand and contract toward and away from the ridge. Very wide roofs can be fixed at midspan and expand and contract toward and away from both the cave and the ridge. The design of the rail and
closure assembly 100 takes full advantage of the floating features of contemporary roofing structures, and when a skylight is so secured to the roof panel elevations, the skylight assemblies themselves are able to draw strength from the structural load bearing capacity of the standing seam roof profile. - Shown in
FIG. 9 is the panel flat 114,rib 112 andshoulder 116, as well as thestanding seam 118. Theridge cap 120 is also shown, as well as thegap 122 in a rib at the up-slope end of the rail and closure assembly. - The
skylight 130 is supported on the rail andclosure structure 140, as previously described. - The rail and
closure structure 140 is secured by itsside rails fasteners 300 to theskylight frame 132 and to theribs 112 by a series ofrivets 310. - Adjacent the up-slope end of the rail and
closure structure 140, asingle rib 112 is typically cut away to creategap 122, thereby to accommodate drainage at the up-slope end of the system (toward ridge cap 120). This is an important feature for standing seam, architectural standing seam and snap seam roofs. Two ribs can be cut for roofs having an “R” panel profile. - The retained portions of
rib 112 function similar to e.g. flange and web portions of an I-beam, thus to support the side rails 142 and 144 and maintain a watertight seal along the length of the assembly. Internal portions of theribs 112 can be removed to allow additional light from theskylight 130. - A single
bearing plate structure 148 is used for sealing the cut away rib. The bearingplate 148 also provides some support to linkadjacent rib elevations 112, and is typically produced of steel or other material sufficient to provide a rigid substructure to the skylight rail and closure structure. - The rail and
closure structure 140 is shaped in such a manner that the skylight can be easily fastened directly to the rail portion, with rivets or other fasteners such as screws and the like. - Looking now to
FIGS. 10 through 12 , anupper diverter 146 provides closure and diversion of water around the up-slope end of the assembly to an adjacent panel flat.Diverter 146 also provides a weather tight seal at the up-slope end of the assembly, with theplate 148. In reference to the side rails 142 and 144 on a standingseam panel roof 110, thediverter 146 generally fits the profile of therib 112 at the region of the cut awaygap 122. The side rails 142 and 144 abut thediverter 146 and the height of thediverter 146 closely matches them in height. Theupper flange 400 of thediverter 146 acts withupper flanges 240 of the side rails 142 and 144 to form the bearing surface of the skylight frame. -
Lower flange 410 ofdiverter 146 runs along the panel flat 114. Thediverter 146 also has adiversion surface 420 andfastener holes 430 along the lower flange. - At one end of
diverter 146 is arib mating surface 440 and at the other end is arib sealing plate 450. -
FIGS. 13 through 15 show thelower closure 150 that is used to maintain a weather tight seal at the lower end of the assembly. Shown in reference to the side rails 142 and 144 inFIG. 13 ,lower closure 150 is adapted to fit the profile of therib 112. The side rails 142 and 144 abutlower closure 150 and the height of thelower closure 150 matches the heights of the side rails. -
Lower closure 150 has anupper flange 500 and alower flange 510, as well as anupstanding closure web 520. Thelower flange 510 includes fastener holes 530. - The
lower closure 150 also includes rib mating surfaces 540 and 550 to provide a tight fit along theribs 112. - Looking now to
FIGS. 16 and 17 , the adaptation of the system for the application of multiple roof penetrating structures is described. A chief aspect of theassembly 100 is the reduction in the number of roof penetrations required to provide daylight to the interior of a structure, as fewer, longer cuts can be made along the roof elevations. This small number of openings can be maintained along a single rib, with one continuous opening, rather than multiple openings, permitting an equal or greater amount of ambient light into the building. - In the case of standing seam roofs, the system provides the ability to remove roof panel material only in the panel flat portion of the panel. This maintains the structural integrity of the roof in that multiple sections of major panel elevations are not removed, as is done to accommodate a “typical” curb assembly. Thus, the roof's structural integrity is not compromised to that extent and there are fewer potential areas for water infiltration, in that the skylight panels can be attached very near the ridge of the building and run to the eave, requiring water to be diverted only once near the ridge of the roof plane and only across one panel flat.
- To the limited extent that cutaways are made to the elevations, these are made small, on the order of a few inches or less, solely for the purpose of allowing drainage past the skylights.
- The rail and
closure assembly 100 is particularly useful for continuous runs of skylights end to end.FIG. 16 shows how two adjacent skylights of the rail andclosure assembly 100 can be affixed along a standingseam panel roof 110. Instead of producing the lights with diverters and lower closures, where adjacent lights abut, the rail andclosure structures 140 are provided with upper and lower standing rib frames 600 and 610 at adjacent ends of theadjacent structures 140. Abatten 620 is provided to secure thesystem 100 against the elements. -
FIG. 17 is a side elevation view of thebatten 620, showing how the batten fits over the adjacent upper and lower standing rib frames 600 and 610. - As one example, skylights can be produced in units of up to 10 feet long, and connected end to end for as long a distance as necessary, as each skylight unit is supported by the ribs of the roof profile. The standing rib elevation (the major corrugation) runs longitudinally along the length of the assembly and mates with the
respective rails assembly 100, regardless of the number ofadjacent structures 140. No water can enter over the top of the rail and closure assembly. - Where it is desired that the skylight starts at the ridge of the roof, a simple flashing can be inserted under the ridge cap.
- Where the ridge cap has a configuration to fit the rib elevations (major corrugations) in the roofing panels, a portion of the one rib may be cut out (approximately 2″), allowing the water from the roof panel above to be diverted onto the next adjacent roof panel.
- If desired, a simple rail enclosure extension could be used to increase the height or distance between the top of the skylight frame and the roof panel, and can be adapted to simply lay over or attach to the top of the rail and closure structure. Such an extension can be produced to extend along the upper flange of the rail and closure structure, to effectively raise the height of the skylight or smoke vent to accommodate different skylight depths or other design features, or to accommodate snow conditions and the like. In this fashion, the rail and closure structure can be produced to a standard height, with upward extensions optionally being used to elevate the overall height of the structure for such varied purposes. Various forms for such an extension are suitable, and the skilled artisan will understand various ways and means of designing and manufacturing such extension to accomplish the goal of added height to the skylight.
- While this invention has been described in conjunction with the specific embodiments outlined above, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the preferred embodiments of the invention, as set forth above, are intended to be illustrative, not limiting. Various changes may be made without departing from the spirit and scope of this invention.
