Abstract
ABSTRACT OF THE DISCLOSURE
A roofing system of the batten type using sheet metal components only.
The battens are formed by folding the side edge portions of adjacent pan sections to form securing channels and upstanding side walls. The side walls are folded inwardly away from the se-curing channels and then downwardly to form downwardly projecting lips spaced inwardly and intermediate of the height of the side walls and a closure cap is slidable along the top edges of the side walls and in engagement with the downwardly projecting lips of adjacent pan sections to bridge and seal the gap formed between the adjacent side walls above the abutting securing channels, the securing chan-nels being held down on the underlying roof structure by fastening screws.

Description
10403B~
This invention relates to sheet metal roofing systems and particularly to roofs of the batten type.
The invention is an improvement over the roofing systems disclosed in my Canadian Patent Application No, 233,923, filed August 21, 1975 in which wood battens are laid on the roof under-surface and the roof undersurface and the battens are covered with a series of pan sections and batten caps, It is also an improve-ment on the system disclosed in my Canadian Patent Application No.
241,047, filed December 4, 1975 in which the battens are in part formed on the edges of the pan sections and when the pan sections are joined together, the mating edges of the pan sections form com-plete battens without separate batten caps, In my previous Cana-dian Patent Application No, 244,714~ filed January 29, 1976 there is disclosed metal battens and pan sections in which upper edge portions of the metal battens are interlocked with edge portions of the pan sections and a batten cap encloses the interlocked battens and pan sections, In the present invention, the slde edges of the pan sec-tions are formed to first provide upstanding side walls and then to provide securing channels located outwardly of the upstanding side walls, The upstanding side walls of the pan sections are each for-med by bending the side edges of the sheet metal from which the pan sections are formed, i'irst upwardly at right angles to the central area of the pan section, followed by bending the terminal portion of the sheet inwardly and then downwardly in the direction of the central portion of the pan section, then upwardly upon itself to form downwardly projecting lips lying parallel with and spaced from the first upwardly bent portion of the side wall, The terminal por-tions of the sheet are then bent outwardly away from the central portion of the pan section and then downwardly to lie in surface contact with the outer facing surface of the first upwardly bent portion of the side walls. The shorter remaining terminal portions .. .... . .. .
of the sheet are then bent at right angles to lie in the same plane as the central portion of the pan section and have their outer edge portions bent upwards to form securing channels located on the outer side of the side walls. The securing channels of adjacent pan sec-tions abut against each other and are held down on the underlying roof structure by fastening screws, A cap member formed of sheet metal is slidably engaged over the top of adjacent side walls of the pan sections and with the downwardly projecting lips of the side walls and bridges and closes the gap between the adjacent side walls.
The object of the present invention is to provide a metal roof in which the mating edges of adjacent pan sections forming the roof covering have upstanding side walls and outwardly located chan-nels for cheaper manufacture and faster assembly of the pan sections on a roof, A ~urther object of the invention is to provide pan sec-tions having side channels which abut with the side channels of ad-jacent pan sections, and the pan sections are secured to the under-lying roof structure by fastening screws passed through the side channels, A further object of the invention is to provide a metal roof formed of pan sections having upstanding side walls and a cap member also of sheet metal is slidably engaged with the adjacent side walls of adjacent pan sections, These and other objects of the invention will be apparent from the following detailed specification and the accompanying draw-ings in which:
Figure 1 is a perspective view of a corner portion of a sloping roof with a metal roofing system according to the present invention, some of whose parts have been removed or cut away for illustrative purposes.
Figure 2 is a transverse section of an intermediate pan section, 104~3~
Figure 3 is a transverse section of assembled adjacent edge portions of two pan sections, together with a cap to complete the batten structure, and showing abutting channels held down on a roof understructure by fastening screws.
Figure 4 is a transverse section of an end pan section.
Referring to the drawings and particularly to Figure 2, each intermediate pan section 5 has its opposite side edges formed with a shallow upstanding edge 6, a relatively narrow base portion 7 and upstanding side walls 8 spaced apart from each other by the relatively wide central base portion 9 of the pan section.
The upstanding side walls 8 are each formed by folding the sheet of metal from which the pan section 5 is formed to form an outer wall member lO,and a top edge portion llprojected inwardly of the wall member 10. The sheet is then folded downwardly to form a wall member 12 and then folded upwardly and inwardly of the wall member 12 to form a downwardly projecting lip 13, The sheet is then further folded downwardly to form the wall member 14 which lies in surface contact with the wall member 10 and in spaced relation to the downwardly projecting lip 13 to leave a gap 15 which has a wldth equal to the thickness of the sheet of metal from which the pan section is formed.
The batten closure cap 16, shown in Figure 3, is generally of inverted U-shape, having a top member 17, outer side members 18 whose lower edges are upturned inwardly to form the inner side mem-bers 19 which are spaced apart from the outer side members 18 a dis-tance equal to twice the thickness of the sheet from which the pan section is formed, The outer pan sections 20, shown in Figure 4, are provided on one edge only with an upstanding side wall 8a similar to the side walls 8 shown in Figure 2, complete with the channel formed by the members 6a and 7a, The opposite side edge of the pan section 20 is inturned downwardly at 21 to engage with the protruding flange 22 ,, .

of the gable starter 23, as shown in Figure 1.
The pan sections 5 and 20 are laid on the roof under-structure 24 with their outer edge upturned members 6 abutting each other and are secured to the roof understructure 24 by the fasten-ing screws 25 passing through the members 7.
The assembly of the closure cap 16 with the upstanding side walls 8 of two adjacent pan sections 5, or with adjacent side walls 8 and 8a, is accomplished by sliding the closure cap 16 so that the top member 17 is in contact with the members 11 of adja-cent side walls, and its side members 19 slide in the gap 15 betweenthe downwardly projecting lips 13 and the wall members 14, Thus all of the members 10, 14 and 13 of the pan sections combine with the members 18 and 19 of the closure cap 16 to form very rigid side walls of the final batten structures, The final batten structures are ~urther held rigid by the fact that members 6 and 7 together ~orm channels whlch abut each other, as shown in Figure 3, and are held down by the ~astening screws 25.
With the above described sheet metal roof, the pan sec-tlons are laid side-by-side on the roof understructure and are se-cured in place by the screws 25 which are accessible only throughthe gap between adjacent upstanding side walls 8 and 8a. When the pan sections are secured in place and the battens are complete by , sliding the caps 16 into engagement with the side walls 8 and 8a, the ~ormed battens although of light weight are rigid enough to re-sist displacement by any outside forces.
This invention relates to sheet metal roofing systems and particularly to roofs of the batten type.
