Abstract
Abstract There is disclosed herein a new roof construction wherein the roofing material is in the form of planks and may be secured directly to rafters, eliminating the need for sheathing and a moisture barrier or membrane such as felt sheeting. The planking has a particular lock joint arrangement which, along with joint drain clips, provides a watertight construction. The exposed surfaces of the planks may be textured to simulate shakes, shingles, tiles or any other texture or pattern desired, and the planks may be of laminated construction, such as of plywood. Not only is the construction watertight, but it is particularly structurally sound and with no exposed fasteners, such as nails and the like. The planks may be readily mass produced and then shipped to the site for installation. A fireproof coating and coloring may be applied to the planks during manufacture thereof.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
180 words
A roof structure which may be applied to the rafters of a building or the like comprising: a plurality of planks having a length between the ends thereof substantially greater than the width between the edges thereof, said planks having a lower, substantially planar surface and an upper surface inclined with respect to said lower surface and terminating in a tongue along the first upper edge thereof, the second lower edge of each of said planks including a groove for mating with the tongue of an adjacent plank, a recessed inclined surface adjacent the upper surface, of said groove a bead of resilient material along said recessed inclined surface which is adjacent said groove near said second lower edge of each plank, said bead abutting and being compressed between the recessed inclined surface and the upper surface of an adjacent plank, whereby said bead performs a sealing and nonload bearing function, the ends of each of said planks having a slot therein forming a receptacle, and clip means mounted within the receptacles defined by the end slots of adjacent planks.
Claim 2
Dependent Claim
180 words
A roof structure which may be applied to the rafters of a building or the like comprising: a plurality of planks having a length between the ends thereof substantially greater than the width between the edges thereof, said planks having a lower, substantially planar surface and an upper surface inclined with respect to said lower surface and terminating in a tongue along the first upper edge thereof, the second lower edge of each of said planks including a groove for mating with the tongue of an adjacent plank, a recessed inclined surface adjacent the upper surface, of said groove a bead of resilient material along said recessed inclined surface which is adjacent said groove near said second lower edge of each plank, said bead abutting and being compressed between the recessed inclined surface and the upper surface of an adjacent plank, whereby said bead performs a sealing and nonload bearing function, the ends of each of said planks having a slot therein forming a receptacle, and clip means mounted within the receptacles defined by the end slots of adjacent planks.
Claim 3
Dependent Claim
16 words
A roof structure as in claim 1 wherein each of said planks is made of plywood.
Claim 4
Dependent Claim
81 words
A roof structure as in claim 1 wherein the depth of each of said grooves at the second lower edge of each plank is substantially deeper than the length of the tongue at the first edge of each plank to allow securing means to be applied through the first edge of each plank near the first upper edge thereof and inside the tongue thereof and the securing means to be covered by the second lower edge of the respective mating plank.
Claim 5
Dependent Claim
119 words
A roof structure as in claim 3 wherein the upper surface of each of said tongues is substantially coextensive with the upper surface of each respective plank and the lower surface of each tongue is spaced above the lower surface of each respective plank thereby defining a substantially wedge-shaped tongue for each plank, each of said grooves are wedge shaped for mating with the tongue of an adjacent plank, the bottom surface of each said groove and the lower surface of each mating tongue being spaced substantially equidistant from the lower surface of each respective plank, and said recessed inclined surface adjacent said groove is a planar area with its surface parallel to the upper surface of said groove.
Claim 6
Dependent Claim
65 words
A roof structure as in claim 1 wherein each of said clip means comprises a unitary member having a relatively flat base of a length substantially coextensive with the length of said end slots, a pair of upturned sides slightly taller than the height of said end slots, an upturned end extending upwardly from said base, and a downturned tab extending downwardly from said base.
Claim 7
Dependent Claim
74 words
The roof structure of claim 1 wherein said clip means comprises: a unitary member fabricated from a material having some elasticity and having a relatively flat base of a length substantially coextensive with the length of said slots, a pair of upturned sides turned inwardly and forming an angle of less than 90* with respect to said base, an upturned end extending upwardly from said base and downturned end extending downwardly from said base.
Claim 8
Dependent Claim
170 words
A roof structure comprising: an elongated member in the form of a plank having upper and lower surfaces and having a length between the ends substantially greater than the width between the edges thereof, said lower surface being substantially planar and said upper surface being inclined with respect to said lower surface and terminating in a tongue at the upper edge of said member, the lower edge of said member being undercut and including a groove in said undercut portion of said lower edge for mating with the tongue of another member, said groove being substantially deeper than the length of said tongue a recessed inclined surface adjacent the upper surface of said groove, the bottom surface of said groove and the lower surface of said tongue being spaced substantially equidistant from said lower surface, and a bead of resilient material affixed on said recessed inclined surface which is adjacent said groove whereby said bead is capable of performing a sealing and nonload bearing function with an identical adjacent plank.
Claim 9
Dependent Claim
170 words
A roof structure comprising: an elongated member in the form of a plank having upper and lower surfaces and having a length between the ends substantially greater than the width between the edges thereof, said lower surface being substantially planar and said upper surface being inclined with respect to said lower surface and terminating in a tongue at the upper edge of said member, the lower edge of said member being undercut and including a groove in said undercut portion of said lower edge for mating with the tongue of another member, said groove being substantially deeper than the length of said tongue a recessed inclined surface adjacent the upper surface of said groove, the bottom surface of said groove and the lower surface of said tongue being spaced substantially equidistant from said lower surface, and a bead of resilient material affixed on said recessed inclined surface which is adjacent said groove whereby said bead is capable of performing a sealing and nonload bearing function with an identical adjacent plank.
Claim 10
Dependent Claim
24 words
A roof plank as in claim 7 wherein said bead of resilient material is spaced away from the lower edge of said elongated member.
Claim 11
Dependent Claim
36 words
A plank as in claim 7 wherein the ends of said member include slots for receiving an end joint sealing and drain clip, said slots being inclined with respect to said lower surface of said member.
Claim 12
Dependent Claim
13 words
A plank as in claim 7 wherein said member is formed of plywood.
