Title:
BUILDING PANEL
Document Type and Number:
WIPO Patent Application WO/1983/003867
Kind Code:
A1
Abstract:
A building panel (30) having inner and outer faces (32, 50) outlined by opposite ends (45, 49) and upper (34) and lower (36) edges, has opposite ends adapted to closely face the end of an adjacent panel in the same course. The outer face (50) of the panel includes a lower segment (54) of substantially greater surface area adapted for exposure and an upper portion (52) of relatively smaller surface area adapted to underlie a lower portion of one or more panels in a next higher course laid in overlapping relation therewith. One of the ends of said panel includes an overlap end segment (38S) adapted to overlie an underlying end segment (40S) at the other end of an adjacent panel laid up end to end in the same course to form a ship lap end joint between the panels. The overlap end segment (38S) includes a marginal end portion of the outer face (50) with an underside (39) of the segment therebelow, and said overlap end segment is formed to slope from a minimum thickness adjacent the upper panel edge (34) toward a mximum thickness adjacent the lower panel edge (36). The panel (30) includes an underlying end segment (40S) at the other end containing a marginal end portion of the inner face (32) with an upper face (41) of the segment adapted to underlie a sloping underside (39) of the overlap end segment of an adjacent panel and said underlying end segment is formed to slope from a maximum thickness adjacent the upper panel edge (34) toward a minimum thickness adjacent the lower panel edge (36).

Claims:
| 1. | A building panel having inner and outer faces outlined by opposite ends and by upper and lower edges, said opposite ends of said panel adapted to closely face the end of an adjacent panel in the same course, said outer face having a lower segment of substantially greater surface area adapted for exposure and an upper segment of relatively smaller surface area adapted to underlie a lower inner face portion of one or more panels in a next higher course laid in overlapping relation therewith, one of said ends of said panel including an overlap end segment adapted to overlie an underlying end segment at the other end of an adajcent panel laid up end to end in the same course to form a ship lap end joint between panels, said overlap end segment at said one containing a marginal end portion of said outer face with an under¬ side therebelow formed to taper from a minimum panel thickness adjacent said upper edge toward a maximum panel thickness adjacent said lower edge, said panel including an underlying end segment at the other end containing a marginal end portion of said inner face with an outer side adapted to underlie said tapered underside of an adjacent panel and formed to taper from a maximum panel thickness adjacent said upper edge toward a minimum panel thickness adjacent said lower edge. |
| 2. | The building panel of claim 1 wherein said overlap end segment includes spaced apart inner and outer ends normal to and intersecting said under¬ side, said underlying end segment including inner and outer ends normal to and intersecting said outer side. |
| 3. | The building panel of claim 2 wherein said lower segment of substantially greater surface area is embossed to resemble a plurality of individual shinglelike elements laid side by side in a common course and separated by grooves, said grooves tapering from a minimum depth adjacent an upper edge of said lower segment toward a maximum depth adjacent a lower edge of said panel. |
| 4. | The building panel of claim 3 wherein said tapered grooves are open at the lower end on said lower edge of said panel. |
| 5. | The building panel of claim 3 wherein said panel is dimensioned to have a thickness at the lower end of said grooves which is similar to the panel thickness of said underlying end segment adjacent the lower edge of said panel. |
| 6. | The building panel of claim 3 wherein said tapered grooves have upper ends terminating at or below said upper segment of relatively smaller surface area of said outer face. |
| 7. | The building panel of claim 6 wherein said tapered grooves break out onto said outer face of said panels at or below said upper setment of rela¬ tively smaller surface area. |
| 8. | The building panel of claim 1 wherein said underside of said overlapping end segment and said outer side of said underlying segment are sub¬ stantially flat and extend between said upper and lower edges of said panel. |
| 9. | The building panel of claim 3 formed of wood fibres pressed to a substantially uniform thickness overall except for variations in said embossed outter face, at said grooves and at said end segments. |
| 10. | The building panel of claim 3 including a course offset guide mark along said upper edge spaced a selected distance from one of said end segments on said upper segment of relatively smaller surface area of said outer face. |
