Description:
ROOFING PANEL SUPPORT AND ROOFING SYSTEM AND METHOD OF INSTALLATION

TECHNICAL FIELD

The present disclosure relates generally to roofing systems, for example, suitable for covering the roof of a house or other building. The present disclosure relates more particularly to a roofing panel support configured to hold secure a roofing panel on a roof structure.

BACKGROUND ART

Roofing systems typically include a roof surface structure formed by a roofing frame that provides the overall shape of the roof. A surface layer may then be formed over and supported by the frame. The surface layer frequently includes a decking or sheathing that is covered by one or more weather resistant layers. For example, roofs are often covered with shingles or panels that shed water and protect the roof from weather. Moving up the slope of the roof, rows of shingles or panels are placed on top of lower rows so that water may be directed away from the surface structure. Various types of shingles and panels can be secured over the surface structure, for example, by using roofing nails or a support frame.

Some roofing systems include solar elements in order to utilize solar energy that is received at the roof surface. For example, some roofing systems include solar panels secured to the roof or photovoltaic cells embedded within roofing panels. Accordingly, such roofing systems can produce electricity, which may offset energy costs and reduce the environmental impact of the structure. On the other hand, roofing systems that produce electricity may be vulnerable to electrical accidents. For example, if components of the roofing system, such as roofing panel supports, become electrically connected to a current source, they can present a danger to anything or anyone that contacts the supports.

The present inventors have determined that roofing panel supports that are configured to enhance electrical safety of the roofing system would be attractive to builders and customers.

As described above, the present inventors have determined that roofing panel supports that are configured to enhance electrical safety of the roofing system would be attractive to builders and customers.

Accordingly, one aspect of the disclosure is a roofing panel support including a bracket and a first hook coupled to the bracket. The bracket includes a support platform with a top end, a bottom end, a first leg extending rearward from a first side of the support platform and a second leg extending rearward from a second side of the support platform. The first leg includes a first lower edge and a first slit extending upward into the first lower edge. The second leg also includes a second lower edge and a second slit extending upward into the second lower edge. The first hook is disposed below the bottom end of the support platform and includes an upward facing opening configured to receive a bottom edge of the roofing panel. The roofing panel support also includes a conductive malleable strip configured to be received in the first slit so as to provide an electrical connection between the bracket and a support structure.

Such a roofing panel support is shown in perspective view in FIG. 1. Roofing panel support 100 includes a bracket 102 with a support platform 104 having a top end 106 and a bottom end 108. Bracket 102 also includes a first side 110 and a second side 112. Extending rearward from first side 110 of bracket 102 is a first leg 114 that runs the length of bracket 102 from the top end 106 to the bottom end 108. First leg 114 includes a short lower section 116 and a deeper upper section 118 that extends further back from support platform 104 than lower section 116. First leg 114 transitions from the upper section 118 to the lower section 116 along a lower edge 120 that faces toward bottom end 108. First leg 114 also includes a first slit 122 that extends upward into lower edge 120. First slit 122 is configured to receive part of a support structure in order to secure roofing panel support 100 to the support structure. For example, FIG. 1 shows a batten 180 that includes a flange 182 configured to be inserted into first slit 122 so that bracket 102 is held firmly on batten 180. Bracket 102 also includes a second leg with a similar configuration to first leg 114 that also includes a slit for receiving the batten 180.

The terms top and bottom, as well as upper and lower, as used herein, refer to a direction that is along the slope of the overall roofing structure and the individual roofing panels. In contrast, the directions perpendicular to the roofing structure are referred to herein as front and rear. Thus, a front surface may be exposed while the corresponding rear surface may face the support structure of the roof. In addition to bracket 102, roofing panel support 100 also includes a first hook 142 disposed below the bottom end 108 of support platform 104. First hook 142 is positioned at the first side 110 of bracket 102 and includes an upward facing opening 144 configured to receive a bottom edge of a roofing panel. First hook 142 is secured to bracket 102 such that the weight of a roofing panel held in first hook 142 will be transmitted from first hook 142, through bracket 102 to batten 180 of the support structure. A similarly configured second hook 143 is positioned at the second side 112 of bracket 102 and is also configured to receive the bottom edge of a roofing panel.

Roofing panel support 100 also includes a conductive malleable strip 150 configured to be received in first slit 122 and in contact with the batten 180. For illustration, the conductive malleable strip 150 is shown between batten 180 and first slit 122 prior to insertion of batten 180 into first slit 122. The interior surface of first slit 122 is electrically conductive. Accordingly, the placement of conductive malleable strip 150 within first slit 122 can help provide an electrical connection between bracket 102 and batten 180. This allows bracket 102 and batten 180 to be electrically bonded to one another via conductive malleable strip 150. By electrically bonding bracket 102 and batten 180, these components have the same electrical potential and current can freely pass from one to the other. Moreover, the bracket 102, batten 180, and any other components they are electrically bonded to can be collectively connected to an electrical ground so as to electrically ground the entire supporting structure. Accordingly, current can be dissipated to the electrical ground in the event of an electrical fault or surge, a lighting strike or an accidental short circuit.

The conductive malleable strip may also aid the structural connection between the bracket and the batten. Because the conductive malleable strip can conform to the shape of the bracket and/or batten, the conductive malleable strip can be pushed into the slit of the bracket even when the thickness of the combination of the batten and conductive malleable strip is slightly greater than the opening of the slit. This can simplify manufacturing, as it may allow for the dimensional tolerance of the batten thickness or slit opening width to be reduced.

The term malleable, as used herein, refers to the ability of the conductive malleable strip to conform to the shape of the first slit when pressed between the material of the bracket and the connected component of the support structure. The conductive malleable strip may also be referred to as pliable, ductile, pliant, soft, workable, flexible, or adaptable. For example, in some embodiments, the conductive malleable strip is formed of a softer material than the bracket. Thus, when the conductive malleable strip is pressed against the bracket, the conductive malleable strip may deform in order to conform to the shape of the bracket. For instance, in some embodiments, the material of the conductive malleable strip has a lower grade on the Mohs scale than the material of the bracket. For example, in some embodiments, the material of the conductive malleable strip is at least one grade lower on the Mohs scale than the material of the bracket. Accordingly, when the bracket and conductive malleable strip are pressed together, the bracket will substantially hold its shape while the conductive malleable strip will deform if it is formed of a softer material.

FIG. 2 shows a detailed side view of a portion of bracket 102 around slit 122 and illustrates the connection between the inner edge of slit 122, conductive malleable strip 150, and flange 182 of batten 180. As shown, slit 122 extends upward from lower edge 120 and the upwardly extending flange 182 is inserted into slit 122. Likewise, conductive malleable strip 150 is also positioned within slit 122 and provides an electrical connection between bracket 102 and the flange 182 of batten 180.

In certain embodiments of the roofing panel support as otherwise described herein, an outer surface of the bracket is conductive. For example, in some embodiments, the entire bracket is conductive, such that the bracket is capable of conducting electricity through the interior of the bracket and is able to receive or discharge current through its outer surface. In view of the conductivity of the outer surface of such a bracket, if an object with an electrical charge contacts the surface of the bracket, current may flow through the bracket. In other embodiments, the surface of the bracket includes a treatment or coating that limits the conductivity of the outer surface. For example, in some embodiments, most of the outer surface of the bracket is insulated. In such a case, a conductive interior of the bracket may be exposed along the edge of the slit. Accordingly, when the slit receives the conductive malleable strip and the support structure, an electrical connection can be achieved despite the insulated outer exterior of most of the bracket.

In some embodiments, the material of the conductive malleable strip has a similar anodic index as the material of the bracket. As will be known to one skilled in the art, there may be advantages in having the conductive malleable strip and materials that it contacts have a low difference in anodic index. For example, in some embodiments, the conductive malleable strip has an anodic index that differs from the anodic index of the bracket by no more than 0.60V, e.g., no more than 0.50V, e.g., no more than 0.45V. Further, it has been found that the potential for galvanic action, which may result in rusting and other undesirable conditions, may be reduced by further similarity between the anodic index of the material of the conductive malleable strip and materials it contacts. Accordingly, in some embodiments, the conductive malleable strip has an anodic index that differs from the anodic index of the bracket by no more than 0.40V, e.g., no more than 0.35V, e.g., no more than 0.30V. Further, in some embodiments, the conductive malleable strip and other materials it contacts, such as the material of the hook, as described further below, has a difference in anodic index of no more than 0.60V, e.g., no more than 0.50V, e.g., no more than 0.40V, e.g., no more than 0.35V, e.g., no more than 0.30V. For example, in some embodiments, the conductive malleable strip incudes a material comprising aluminum, tin or lead.

In certain embodiments of the roofing panel support as otherwise described herein, an edge of the first slit includes a row of teeth. For example, as shown in FIG. 2, rear edge 126 of slit 122 includes a row of teeth 128 formed as sharp projections that extend into the interior of slit 122. The sharp configuration of teeth 128 help promote a strong electrical connection between bracket 102 and conductive malleable strip 150, as the teeth bite into the surface of conductive malleable strip 150 thereby penetrating the conductive material. Further, in some embodiments, the teeth may be configured to scratch the surface of the support structure directly, such as a flange extending into the slit. For example, in some embodiments, the teeth penetrate entirely through the conductive malleable strip to engage the flange. In other embodiments, the conductive malleable strip is disposed only on an opposite side of the flange as the teeth, such that the conductive malleable strip promotes a strong connection on one side of the flange and the teeth promote a strong connection on the other.

While slit 122 of bracket 102 includes teeth on the rear edge 126 of slit 122, in other embodiments, the slit includes teeth on the front edge. Furthermore, in some embodiments, the slit includes teeth on both the front and rear edges.

In certain embodiments of the roofing panel support as otherwise described herein, the conductive malleable strip includes a folded structure with a front flap and a rear flap, and the conductive malleable strip is configured to surround a flange of the support structure such that the front flap is positioned against a front edge of the first slit and the rear flap is positioned against a rear edge of the first slit. For example, as shown in FIG. 2, conductive malleable strip 150 has a folded structure including a front flap 154 disposed between the front edge 124 of slit 122 and flange 182 of batten 180. A rear flap 156 is attached to front flap 154 by a bend so as to form a folded structure of conductive malleable strip 150. Rear flap 156 is positioned between rear edge 126 of slit 122 and flange 182, such that the teeth 128 of rear edge 126 bite into rear flap 156. The folded structure of conductive malleable strip 150 allows the strip to aid the electrical connection between batten 180 and bracket 102 on both the front and rear sides of flange 182 of batten 180.

In certain embodiments of the roofing panel support as otherwise described herein, the conductive malleable strip is configured to extend to the second slit of the second leg. A front elevation view of such a roofing panel support is shown in FIG. 3. Roofing panel support 300 includes a bracket 302 with a top end 306, a bottom end 308, a first side 310 and a second side 312. A first hook 342 is disposed below the bottom end 308 of bracket 302 and is configured to hold up a roofing panel resting on bracket 302. In particular, bracket 302 includes a support platform 304 that is configured to receive the roofing panel. A portion of support platform 304 is cut away to more clearly show a rear part of a first leg 314 and a second leg 315 of bracket 302.

Each of the first leg 314 and second leg 315 includes a respective slit 322, 323 that receives a flange 382 of a batten 380 such that bracket 302 is secured to batten 380. To enhance the structural and electrical connection between bracket 302 and batten 380, a conductive malleable strip 350 is positioned between flange 382 of batten 380 and the respective edges of first slit 322 and second slit 323. In particular, conductive malleable strip 350 has a sufficient width to extend from first slit 322 to second slit 323.

In other embodiments, the width of the conductive malleable strip is configured to be placed within the slit of only one leg of the bracket. For example, in some embodiments, a conductive malleable strip that is inserted into the slit of a single leg of the bracket provides sufficient electrical and structural connection between the bracket and the batten. In other embodiments, a pair of conductive malleable strips are used such that the slit of each leg is engaged by a separate conductive malleable strip.

In certain embodiments of the roofing panel support as otherwise described herein, the conductive malleable strip is plated on a flange of a batten. Such a roofing panel support is shown in FIG. 4. Roofing panel support 400 includes a bracket 402 and a hook 442 extending below a bottom end of bracket 402. Bracket 402 includes a first leg 414 with a slit 422 formed in a lower edge 420 of the leg. A batten 480 is configured to engage slit 422 and includes a flange 482 that is sized to fit between the edges of slit 422. A conductive malleable strip 450 is plated onto a front surface of flange 482 so as to provide strong structural and electrical contact between conductive malleable strip 450 and batten 480. When flange 482 is inserted into slit 422, the conductive malleable strip 450 is configured to conform to the shape of bracket 402, which provides a similarly strong connection between conductive malleable strip 450 and bracket 402. In certain embodiments of the roofing panel support as otherwise described herein, the first hook is formed by a metal clip secured to the bracket. The metal clip includes an upper portion that extends behind the support platform, and an exposed lower portion that extends below the bottom end of the bracket and includes the first hook. For example, as shown in FIG. 1, first hook 142 of roofing panel support 100 is formed by a wire metal clip 140 that includes a lower portion 141 extending down from the bottom end 108 of bracket 102. An upper portion 145 of metal clip 140 extends upward behind support platform 104 and is shown in FIG. 1 using dashed lines. First hook 142 is part of the exposed lower portion 141 that is not shielded behind support platform 104.

The use of a wire metal clip to form the first hook allows provides a thin strong structure to support a roofing panel that is easily connected to the bracket. In view of the relatively small size of the wire metal clip, the first hook can support the roofing panel without being visually obtrusive within the aesthetic of the roofing structure. In other embodiments, the hook is formed by a cast, molded, carved or printed component, or a bent sheet, such as a bent metal sheet. Further still, in some embodiments, the hook is integrally formed with the bracket in a single piece of material.

In certain embodiments of the roofing panel support as otherwise described herein, the conductive malleable strip includes a forward extension configured to contact the metal clip. FIGS. 5A illustrates such a conductive malleable strip. Conductive malleable strip 550 is configured to extend from a slit in the first leg of a bracket to the slit in a second leg of the bracket. Conductive malleable strip 550 has a folded structure that includes a rear flap 556 extending across the entire width of the strip and a front flap 554 formed in two sections 551, 552. The first section 551 of front flap 554 is configured to contact one leg of the bracket while the second section 552 is configured to contact the other leg of the bracket. Between the first section 551 and second section 552 of front flap 554, conductive malleable strip 550 includes a forward extension 558 configured to engage a metal clip that forms the first hook of the roofing panel support.

FIG. 5B illustrates a cross-sectional side view of part of a roofing panel system that includes conductive malleable strip 550. As shown, the roofing panel system includes a bracket 502 that is secured to a flange 582 of a batten 580 by the insertion of the flange 582 within the first slit 522 of the first leg 514 of bracket 502. An outline of a portion of first leg 514 of bracket 502 is shown using dashed lines so that components behind first leg 514 are visible. The conductive malleable strip 550 is positioned to surround flange 582 with the rear flap 556 positioned behind flange 582 and the front flap 554 positioned in front of flange 582. Accordingly, rear flap 556 is interposed between flange 582 and the rear edge 526 of slit 522 while front flap 554 is interposed between the flange 582 and the front edge 524 of slit 522, thereby forming a structural and electrical connection between the batten 580 and bracket 502. Forward extension 558 extends toward support platform 504 and contacts metal clip 540. Accordingly, an electrical connection can also be established between batten 580 and metal clip 540.

In certain embodiments of the roofing panel support as otherwise described herein, the forward extension is formed as a tab that abuts the metal clip. For example, forward extension 558 of conductive malleable strip 550 is formed as a tab that extends outward from the upper edge of rear flap 556.

In other embodiments, the forward extension of the conductive malleable strip includes a lateral projection that contacts the metal clip. Such a conductive malleable strip is shown in FIGS. 6A-6C. Conductive malleable strip 650 has a folded structure that includes a rear flap 656 and a front flap 654 that are configured to surround a flange of a support structure and fit within a slit of a bracket. Conductive malleable strip 650 also includes a forward extension 658 configured to engage a metal clip that forms the first hook of the roofing panel support. In particular, forward extension 658 includes a lateral projection 659 that is configured to contact the metal clip.

FIG. 6B illustrates a cross-sectional bottom view of part of a roofing panel system that includes conductive malleable strip 650. As shown, the roofing panel system includes a bracket 602 including a support platform 604 and first leg 614. A flange 682 of a batten is received in a slit 622 in the first leg 614. The conductive malleable strip 650 is positioned to surround flange 682 with the rear flap 656 positioned behind flange 682 and the front flap 654 positioned in front of flange 682, thereby forming a structural and electrical connection between the batten and bracket 602. Forward extension 658 projects toward support platform 604 and includes a lateral projection 659 extending toward first leg 614. The lateral projection 659 extends along metal clip 640 making contact with the metal clip 640. Accordingly, an electrical connection can also be established between the batten and metal clip 640.

FIG. 6C illustrates a cross-sectional bottom view of part of a roofing panel system having a similar configuration to FIG. 6B. As shown, the conductive malleable strip 650 is again positioned to surround flange 682 and be inserted into the slit 622 in first leg 614. Forward extension 658 of conductive malleable strip 650 projects toward support platform 604 and includes a lateral projection 659 that extends around metal clip 640 so as to partially surround metal clip 640. The lateral projection 659 extends along metal clip 640 making contact with the metal clip 640. Such a configuration can provide additional contact between the conductive malleable strip 650 and metal clip 640.

In another aspect, the disclosure provides a roofing panel support including a bracket and a metal clip secured the bracket. The bracket includes a support platform with a top end and a bottom end, a first leg extending rearward from a first side of the support platform, and a second leg extending rearward from a second side of the support platform. The metal clip includes an upper portion that extends behind the support platform, and an exposed lower portion that extends below the bottom end of the bracket. The exposed lower portion includes a first hook with an upward facing opening configured to receive a bottom edge of the roofing panel. The roofing panel support also includes insulation surrounding the exposed lower portion of the metal clip.

Such a roofing panel support is shown in FIG. 7. Roofing panel support 700 includes a bracket 702 with a support platform 704 having a top end 706 and a bottom end 708. Bracket 702 also includes a first side 710 and a second side 712. Extending rearward from first side 710 of bracket 702 is a first leg 714 that runs the length of bracket 702 from the top end 706 to the bottom end 708. Bracket 702 also includes a second leg with a similar configuration to first leg 714 that also includes a slit for receiving the batten 780.

In addition to bracket 702, roofing panel support 700 also includes a wire metal clip 740 coupled to bracket 702. Metal clip 740 includes an exposed lower portion 741 that extends below the bottom end 708 of bracket 702 and an upper portion 745 that is positioned behind support platform 704 of bracket 702. Exposed lower portion 741 includes a first hook 742 with an upwardly extending opening 744 configured to hold a roofing panel.

When a roofing system using roofing panel support 700 is fully installed, a roofing panel is placed in front of support platform 704 of bracket 702 and obscures most of roofing panel support 700. However, part of the lower portion 741 of metal clip 740 extends around the lower edge to the front of the roofing panel, where it is both visible and accessible. Adding insulation 760 over this exposed portion of metal clip 740 provides electrical protection against electrical discharges through the metal clip 740. The insulation may also help meet certain regulations that require any exposed metal of a solar roofing systems to be grounded. Insulating parts of the metal clip may obviate the need to ground the metal clip, as these parts may not be considered to be exposed.

In certain embodiments of the roofing panel support as otherwise described herein, an outer surface of the bracket is conductive. For example, in some embodiments, the bracket is entirely made of a conductive material. Despite both the bracket and metal clip being conductive in such an embodiment, sufficiently electrically bonding the metal clip to the bracket may be difficult. By including insulation over the exposed portion of the metal clip, the need to ground the metal clip may be avoided. Moreover, because the bracket is positioned behind the roofing panel and not exposed, it may not need to be insulated.

Similar to roofing panel support 100, shown in FIGS. 1 and 2, the first leg 714 of bracket 702 includes a first lower edge 720 and a first slit 722 extending upward into the first lower edge 720.
