Brackets for installing building attachments

Abstract

Roof brackets for attaching a structure such as a patio cover to a building, and methods for installing the brackets. The brackets have a saddle for receiving a support beam of the structure. The brackets can be attached to the building roof, but do not penetrate the roof substrate, thus preventing leakage and other structural problems. The roof brackets comprise a plate that is installed between the roof substrate and the shingles or tile on the roof. The brackets are available in different configurations depending on the roof pitch for easy installation. One roof bracket has a riser so that the saddle is lifted above the roof. Another roof bracket is configured so that when installed the saddle is located beyond the edge of the roof. Other brackets can be attached to the rafters under the roof. These also come in different configurations depending on roof pitch, and they are configured to extend below and outward from the fascia.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

(18) Embodiments of the present invention are brackets to install a lattice or solid patio cover by attaching it to an existing building without requiring attachment to the building wall or fascia. The brackets are preferably either roof mounted brackets or rafter (under-mount) brackets. Unlike typical roof brackets, the brackets of the present invention do not have to be mounted through the roof; they can be mounted under shingles or tiles without penetrating the roof itself. The brackets preferably comprise powder coated steel and are preferably available in all standard roof pitches. By ensuring consistent pitch angles, a patio cover is true and level and conforms to building codes for rainwater drainage. The powder coating preferably matches the color of the patio cover and/or rafter. The brackets are preferably structurally strong enough so that only one bracket per support post 5 as shown in FIG. 1 is required, per engineering standards. Support posts 5 are typically spaced at least eight feet apart. For existing brackets, one typically needs to be installed every 24″ on the building, but brackets of the present invention are preferably sufficiently load bearing so that one needs to be mounted only every eight feet (or more). The present invention thus requires far fewer brackets to support a given load, and because the brackets are much easier to install, installation time is greatly reduced. The present brackets are preferably sufficiently strong to support weight bearing loads heavier than those of patio covers, for example loads due to structures such as wood or metal architectural features, solar panels, roof decks, trellis, arbors, walkways, and the like. It is not necessary to remove existing rain gutters to install the present brackets. The present brackets provide added height under the patio cover, providing adequate slope for drainage while preserving views and enabling the use of hanging accessories such as ceiling fans. Brackets of the present invention are typically less obtrusive than typical “L” brackets, and are more resistant to seismic events.

(19) Roof brackets of the present invention preferably comprise two steel components, a base plate and a saddle (or beam seat), that are preferably welded together, although any material may be used. The base plate for the roof mount bracket is preferably formed from ¼′×3″ flatbar and comprises an optional riser and a roof mounted plate. The base plate for the rafter or under-mount bracket is preferably water jet cut from ¼′ steel plate to the desired pitch, including the mounting holes. The saddle is preferably manufactured by forming a piece of 3/16″×3″ steel flat bar into “U” shape that will accommodate a typical patio cover support beam. The two pieces are then preferably welded with a typical ¼′ fillet weld. The bracket is then preferably sandblasted, primed with a zinc based primer, and then powder coated to the desired color. Alternatively the entire bracket may comprise a single molded or cast piece.

(20) FIG. 3 shows a high roof mount bracket of the present invention comprising beam seat or saddle 10, riser 20, and roof mounted plate 30. The roof mounted bracket can be produced in different models having different angles between riser 20 and roof mounted plate 30 corresponding to different standard roof pitches. FIG. 4 shows engineering drawings of an example of the high roof mounted bracket. As shown in FIGS. 3 and 5, the roof mounted bracket is installed under the roof material and is attached, preferably by screwing, to the roof substrate. In the case of the roofing material comprising shingles, the shingles can be lifted up to install the bracket; in the case of tiles, the tiles can be removed and then replaced after the brackets are installed. The bracket installation does not require any penetration through the roof substrate, thus minimizing the risk of roof leakage and/or damage. FIG. 6 is a photograph of a finished patio cover installed using roof mounted brackets of the present invention.

(21) FIG. 7 shows a picture of a low roof mount bracket, an alternative embodiment of a roof mount bracket of the present invention, comprising saddle 10 and roof mounted plate 35. This embodiment does not have a riser and is particularly useful for applications where the patio cover beam must be horizontally offset from the edge of the roof. FIG. 8 shows a close up view of saddle 10 holding patio cover beam 40, and shows that installation can be performed without removal of rain gutter 45. FIG. 9 shows drawings of the low roof mount bracket embodiment having different pitches and showing the plate installed under roof tiles or shingles. FIG. 10 shows engineering drawings of an example of a low roof mount bracket.

(22) FIG. 11 shows three views of rafter brackets of the present invention, each corresponding to a different roof pitch. FIG. 12 shows corresponding engineering drawings of the rafter brackets. As shown in FIGS. 13-15, base plate 50 preferably extends from saddle 10 under fascia 60 of the building and angles upward to enable rafter plate portion 75 for attach to rafter 70. Because base plate 50 is preferably available in all roof pitches, the top of rafter plate portion 75 preferably rests directly against underside 80 of the roof, enabling easy and fast installation so that saddle 10 is substantially automatically vertically oriented as installed, without requiring leveling. This installation eliminates any risk of roof leakage or damage. This bracket can be installed through a slot cut in a soffit if one is present. FIG. 16 is a photograph of a finished patio cover installed using rafter brackets of the present invention.

(23) The user can choose to use roof mounted brackets or rafter brackets, depending on the desired mounting height and roof construction. The desired bracket is attached the roof substrate or roof rafter (respectively) preferably using 4-Simpson SDS style screws. Next the user simply installs the 3″×8″ patio cover support beam into the saddle (beam seat), affixes it with screws and is ready to finish typical patio cover installation.

(24) Although the invention has been described in detail with particular reference to the disclosed embodiments, other embodiments can achieve the same results. Variations and modifications of the present invention will be obvious to those skilled in the art and it is intended to cover all such modifications and equivalents. The entire disclosures of all patents and publications cited above are hereby incorporated by reference.
