ROOFING BATTEN

Abstract

A batten for use in roofing applications is defined by an upside-down U-shaped channel with outwardly projecting horizontal flanges. In certain versions, the legs forming the sides of the channel are asymmetrical to allow vertical orientation of at least one of the legs when installed on an angled roof. This improves strength and load bearing of the installed member, and allows it to provide a fall barrier for roof installers. In certain versions, one of the flanges has a ribbed impact reduction zone. This zone deforms when a building anchor, such as a nail, passes through it to anchor the member to a roof. The deformation prevents anchors fired from conventional equipment from passing completely through the member and holds the anchors more securely in place.

DETAILED DESCRIPTION OF EXEMPLARY VERSIONS OF THE INVENTION

[0025] Referring to FIG. 1, a batten 1 has a horizontal top 2 connecting a first leg 3 and a second leg 4, resulting in a channel with an upside-down U-shaped cross-section. First leg 3 is at a first internal angle 9 to horizontal top 2, while second leg 4 is at a second internal angle 10 to horizontal top 2. Flange 5 extends substantially horizontally outward from the end of first leg 3 opposite horizontal top 2. Flange 6 extends substantially horizontally outward from the end of second leg 4 opposite horizontal top 2. Flanges 5 and 6 also feature turn ups 7 at their free ends. FIG. 1 also shows a vertical axis of batten 1 extending from A to A.

[0026] A preferred version of the invention utilizes a first inclined leg 3 and a second substantially vertical leg 4. Another preferred version of the invention utilizes a ribbed flange 5 and a flat flange 6, with ribbed flange 5 featuring an impact reduction zone 8.

[0027] The preferred version of the invention is made of steel. In certain versions of the invention, the steel is a light gauge steel (i.e., thinner than 24 gauge). In certain versions of the invention, first internal angle 9 is an angle of at least 105 or at least 115 with horizontal top 2. Second internal angle 10 is an angle of at least 92 with horizontal top 2. In certain versions of the invention, the total height of batten 1 is no more than approximately 25 mm and the total width of batten 1 is no more than approximately 60 mm.

[0028] In one preferred version of the invention, shown in FIGS. 1 through 6, batten 1 is asymmetrical about the vertical axis, i.e., each of the legs has a different length and angle to the other. The specific lengths of horizontal top 2, inclined leg 3, and substantially vertical leg 4 can be altered, but the asymmetrical nature of batten 1 of the invention is preferred. The asymmetric shape allows attachment of batten 1 with flange 5 on the lower side of batten 1 to align the substantially vertical leg 4 to a position that is optimal for engagement with a roof tile. A top downwardly extending lip of the roof tile engages substantially vertical leg 4 in such a way that the tile can then be easily, permanently attached to batten 1. Batten 1 provides a smooth surface over which the tile lip can be hooked, allowing the tile to stay in place until anchored to batten 1.

[0029] The asymmetric shape also means that when installed to angled roof members, such as wooden or steel trusses on a pitched roof, both legs of batten 1 end up being almost vertical with respect to the ground. This aligns both legs with the direction of gravity and helps to provide improved strength and load bearing. As a result, batten 1 is strong enough to provide a fall barrier for roof installers. Typical roofs have a pitch of approximately 15-30; during installation, when the shorter side (substantially vertical leg 4) is placed on the higher side of the roof, the longer side (inclined leg 3) will be close to vertical. This compares to traditional battens where the legs are of the same length and at the same angle to the horizontal top.

[0030] The improved strength of batten 1 means it can be used as a batten or top hat on any roof member, spaced appropriately for any roofing material, such as, but not limited to, tiles or sheet metal, and still provide a fall barrier for the roofing contractors or a place to stand while the roofing material is installed. The strength of batten 1 means it is strong enough to meet all appropriate standards for roofing battens and can carry the loads of roofing material, even the heavy weight of a concrete tile roof.

[0031] The exact internal angles and length of the legs may be adjusted to optimize the alignment of the longer leg for different roof pitches. The cost of retooling the roll forming machine that makes the battens may increase expenses, but if a manufacturer always made roofs with the same pitch, the variations could be worked out to provide the optimal arrangement for that roof pitch. The values used in the version shown are most useful for roofs with pitches of 20-30, which are common in Australia, but could be customized to roof pitches ranging from 4 to 55.

[0032] Other preferred versions of the invention with ribbed flange 5, as shown in FIGS. 1 through 6, allow batten 1 to be installed on the wooden roof trusses using a standard building anchor, such as a nail projected from a nail gun. Ribbed flange 5 incorporates at least two ribs; the preferred version of batten 1 has three ribs. The width of ribbed flange 5 can be altered, but is preferably wide enough to allow a nail gun to be placed in such a way to insert a nail. Ribbed flange 5 also has turn up 7 of at least 90 at its distal end. The preferred version has a turn up 7 of at least 110.

[0033] The ribbing (which may also be called rippling, striations, ridges or undulations) strengthens the material of batten 1 and helps to keep the building anchor in batten 1. The ribbing also forms impact reduction zone 8, allowing the energy in a projected building anchor to be dissipated or absorbed and thereby reducing its impact. As a result, the installers may not need to have extra tools or significantly adjust or alter their standard tools and practices of the trade. Furthermore, the force of the building anchor being installed deforms the ribs in such a way that the material folds over and covers the head of the building anchor, holding the building anchor more securely and strongly in a recess, and aiding the connection between building anchor, batten, and roof member.

[0034] The added feature of ribbed flange 5 means batten 1 can be easily installed on either a steel or wooden frame set of roof members, such as trusses. When it is used on wooden framed roof trusses, roofing contractors do not need to change equipment or alter their roofing practices. As one example, a nail gun can still be used to attach batten 1, and the nail will not pass through the material of flange 5 of batten 1.

[0035] In versions of batten 1 using ribbed flange 5, flat flange 6 has no ribs and is not as wide as ribbed flange 5. Flat flange 6 also has turn up 7 of at least 90 at its distal end. The preferred version has a turn up 7 of at least 110.

[0036] As shown in FIG. 7, during installation a user would place batten 1 on top of at least one roof member, such as, but not limited to, a truss. If batten was asymmetrical and the roof member an angled roof member, the user would orient the batten such that the substantially vertical leg was located further up the angled roof member. The user would then project at least one building anchor, such as a nail from a nail gun, partially through flange 5 and into the roof member to connect the roof member and batten 1. If batten 1 included impact reduction zone 8 with deformable ribs, the user would project the building anchor partially through impact reduction zone 8 such that the building anchor deformed at least one of the deformable ribs. Once batten 1 was secured, the user could cover batten 1 with roofing material, such as sheet metal or roofing tile, and project at least one additional building anchor partially through the roofing material and into the horizontal top to secure the roofing material to batten 1.

[0037] Batten 1 of the invention may also be useful in other areas. Batten 1 may be useful for being a support for solar panels, satellite dishes, or other objects mounted on roofs. Any version of batten 1 may also be part of a roof system including at least one roof member, and at least one building anchor partially extending through flange 5 and into the roof member to connect the roof member and batten 1. The building anchor may be a nail from a nail gun, while the roof member may be an angled truss, or a wooden or steel roof member.

[0038] Throughout this document, unless the context requires otherwise, the words include and including (and variations such as comprise and comprising) will be understood to include the stated element (or group of elements), as well as additional instances of the stated element (or group of elements).

[0039] It should also be understood that various terms referring to orientation and position used throughout this documente.g., horizontal topare relative terms rather than absolute ones. In other words, it should be understood (for example) that the horizontal top referred to may in fact be located at a non-horizontal angle, or at the bottom of the batten, depending on the overall orientation of the apparatus. Thus, such terms should be regarded as words of convenience, rather than limiting terms.

[0040] Where a measurement or other value is qualified by the term approximately, about, or like termsfor example, approximately 50 mmthis can be regarded as referring to a variation of 10% from the noted value. Thus, about 50 mm can be understood to mean between 45 and 55 mm.
