DETAILED DESCRIPTION OF THE DRAWINGS

(12) FIGS. 1A to 6 illustrate various views of a first embodiment of the present batten, as follows: batten 10 comprises an elongated body 20; a pair of upwardly extending side walls 30 running along opposite sides of elongated body 10; and a plurality of pre-formed notches 40 in side walls 30. The pre-formed notches 40 are disposed at spaced-apart intervals along the length of each of side walls 30. Preferably, pre-formed notches 40 are spaced apart equidistantly from one another, and are V-shaped. As will be explained herein, notches 40 assist in cutting or breaking batten 10 into desired lengths such that measured sections of the batten can be removed (and the batten best sized to fit the job requirements). In this particular embodiment, batten 10 has a length of 12 inches, but it to be understood that the present invention encompasses battens of any length.

(13) In preferred embodiments, roofing batten 10 is made of a plastic polymer. In one embodiment, the plastic polymer is a polypropylene homopolymer. However, it is to be understood that other suitable materials can be used instead. Plastic polymer materials have the advantages of having low moisture absorption resulting in long batten life. In addition, such materials are lightweight for ease of handling and reduced worker injuries. Moreover, such materials are chemically resistant to organic solvents, degreasing agents and electrolytic attack. The preferred materials also offer superior tensile strength.

(14) Optionally, batten 10 may incorporate UV resistant materials (especially in scenarios where the batten is exposed to the environment). Preferably as well, such materials may also be heat tolerant to 200 F, or higher. This heat tolerance provides significant advantages over traditional wooden roofing battens. Such heat tolerance is especially important in the case of solar panel arrays positioned close to the battens.

(15) Yet another advantage of forming the present batten from plastic polymers is that the elongated body 20, the pair of side walls 30 and the fastener housings 60 can all be formed from a single integrated block of plastic polymer material. Such a material can preferably be injection molded from high quality resin to ensure sequential parts are uniform and consistent. Such a preferred material can also be drilled or punctured without fracturing.

(16) As seen best in FIG. 2B, an optional bottom perimeter rib 70 can be provided that extends downwardly from elongated body 20 can also be provided. Together, side walls 30 and bottom perimeter rib 70 each provide strength to the overall structure of the batten.

(17) A plurality of fastener housings 60 are positioned at spaced-apart intervals along a length of the bottom of elongated body 20. As seen in FIG. 4, fastener housings 60 are preferably positioned equidistantly between pre-formed notches 40 in side walls 30. As best seen in the cross-sectional view of FIG. 6, each of fastener housings 60 can have an aperture 62 that passes through elongated body 20, with a top portion of aperture 62 being shaped to receive a countersunk screw head therein. As best seen in FIG. 2B, one embodiment of fastener housing 60 preferably has a supporting wall 64 passing transversely across elongated body 20.

(18) At each of the ends of batten 10, an alternate fastener housing design can be provided. Specifically, as seen in FIG. 2B, fastener housing 66 has a box-shaped structure with walls 66 extending both transversely across elongated body 20 and also longitudinally along elongated body 20. These fastener housings 66 can be positioned at the ends of elongated body 20, as illustrated. Fastener housings 66 offer the advantages of added strength and stability at the ends of batten 10. It is to be understood that additional fastener housings 66 can be positioned mid-way along the length of batten 10, as desired. It is also to be understood that fastener housings 66 can conceivably replace any or all of the fastener housings 60 along the length of batten 10 as desired, all keeping within the scope of the present invention. Although one of end fastener housings 66 will be removed when batten 10 is shortened, it is to be understood that in many (if not most) situations, the full length of batten 10 will be used, and the batten will be affixed to the roof without being shortened. In such situations, having box-shaped fastener housings 66 at both ends of batten 10 will provide increased stability. In most work situations, the majority of battens 10 will be their full length in the final roof assembly, with only some of the battens being shortened as needed (using the present design's easy-to-remove pre-measured sections).

(19) As best seen in FIG. 4, a bottom of each of the fastener housings 60 and 64 projects down below the bottom of elongated body 20. This gap (i.e.: the gap formed between bottom rib 70 and the bottom of the fastener housings 60 and 62) provides drainage channels between the fastener housings 60 and 64 when the batten is fastened to the roof.

(20) The present batten 10 is secured to the roof by positioning screws 80 received into each of the apertures 62 in fastener housings 60. Screws offer improved security and stability as a means to attach batten 10 onto a roof (as compared to traditional nails used for holding wooden battens).

(21) In accordance with the present invention, elongated body 20 can either be cut apart by a pair of shears positioned at one of the V-shaped notches 40, or optionally manually broken apart by applying forces on opposite sides of one of the V-shaped notches. Moreover, should a saw (hand or power) be used to cut the elongated body, the V-shaped notches can be used to guide the saw blade. As seen in FIG. 4, the application of forces F1 and F2 can optionally be used to break batten 10 at notch 40. The advantage of this approach is that the V-shape of the notch focuses the forces at the center of the notch such that the elongated body 20 is broken apart at the notch.

(22) FIG. 7 illustrates an alternate length (e.g.: 48 inches) of the present batten 10. It is to be understood that the length and width of the present batten can be varied, all keeping within the scope of the present invention.

(23) As seen in FIG. 8, indicia 50 are also printed or otherwise labelled on elongated body 20. Alternately, indicia 50 can be printed or otherwise labelled on side walls 30. Indicia 50 indicating measured lengths of the roofing batten at each of the pre-formed notches. As such, the worker knows the overall length of the batten when it is cut or broken to its desired length. In one optional embodiment, indicia 50 represent 1 inch lengths It is to be understood, however, that any suitable length can be used, all keeping within the scope of the present invention.

(24) Lastly, FIG. 9 illustrates a top plan view of a number of battens 10 attached to the roof of a building. As can be seen, a typical roof geometry will necessitate battens of different lengths in its construction.
