Abstract

A closure member of a preferred configuration and the method of making the same. The closure member has a board with a major axis and two panels to sandwich a hollow interior that is partitioned by a plurality of ribs positioned at intervals within the hollow interior, the hollow interior is delimited in a first direction by a pair of opposite end walls. The hollow interior is accessible in a second direction which is substantially traverse to the first direction, and at least one of the two panels is textured during the formation of the board to form a textured outer surface of the closure member, or the hollow interior is filled with a preferred reinforcement means.

First claim

What is claimed is:

1. A closure member, comprising:
a board having a major axis and two panels sandwiching an open ended hollow interior that is partitioned by a plurality of ribs positioned at intervals, the hollow interior is delimited in a first direction by a pair of opposite end walls and is accessible in a second direction which is substantially transverse to the first direction, the hollow interior is closeable in the second direction by a cover;
the hollow interior includes a center region and two side regions, the plurality of ribs include a plurality of first ribs each having a length that extends parallel to the major axis in the hollow interior and at least one second rib that comprises a length that extends parallel to the major axis and a width that extends transverse to the major axis and the plurality of first ribs in the hollow interior but does not reach the end walls;
a portion of the plurality of first ribs and the at least one second rib intersect within the hollow interior to form a plurality of intersections for enhancing structural strength of the closure member relative to a closure member that does not include such intersections, the plurality of first ribs being closer to one another in a region adjacent at least one of the end walls of the board than in a region at or adjacent the center region of the board, at least part of the hollow interior is occupied by reinforcement material;
wherein the panels, the first and second ribs and the opposite end walls are formed integrally as one piece by extrusion, and
wherein the plurality of first ribs extend between and transverse to the two panels.

2. The closure member as claimed in claim 1 , wherein the hollow interior is partitioned by the first and the second ribs to form discrete elongate spaces that extend along the major axis.

3. The closure member as claimed in claim 1 , wherein the hollow interior is partitioned at intervals to form discrete elongate spaces that extend along the major axis.

4. The closure member as claimed in claim 3 , wherein at least one of the discrete elongate spaces is filled with reinforcement material which is preformed into an elongate piece and dimensioned to be fitted into the discrete elongate space.

5. The closure member as claimed in claim 4 , wherein the elongate piece is made of a material selected from a group consisting of wood, plastic and metal.

6. The closure member as claimed in claim 1 , wherein at least one of the panels is textured by way of having one or more grooves thereon.

7. The closure member as claimed in claim 6 , wherein the texture is formed together with the rest of the overall closure member by way of extrusion.

8. The closure member as claimed in claim 1 , wherein at least one of the panels is decorated with a decoration fixed thereto.

9. The closure member as claimed in claim 8 , wherein the decoration is press fit into a groove.

10. The closure member as claimed in claim 8 , wherein at least one of the panels is textured by way of having one or more shaped grooves thereon which are formed together with the rest of the overall closure member by way of extrusion, and the decoration includes a base having a shape corresponding to that of the groove and is attached to the groove.

11. The closure member as claimed in claim 8 , wherein the at least one of the panels includes an aperture for accommodating a part of the decoration, the decoration includes a deformable anchor for insertion into the aperture when compressed and thereafter for abutting an underside of the panel when expanded.

12. The closure member as claimed in claim 8 , wherein the second rib includes an aperture for accommodating a part of the decoration, the decoration includes a deformable anchor for insertion into the aperture when compressed and thereafter for abutting an underside of the second rib when expanded.

13. The closure member as claimed in claim 12 , wherein the aperture on the second rib is aligned with an aperture on the at least one of the panels and the decoration includes two deformable two deformable anchors for insertion into respective apertures.

14. The closure member as claimed in claim 8 , wherein the decoration is fixed to the panel by a two part coupler, with one part being provided on an inner side of the at least one of the panels coupling with another part being provided on an outside of the at least one of the panels.

15. The closure member as claimed in claim 1 , wherein the board includes an aperture which extends across the hollow interior and beyond the panels to form a through hole for accommodating a window with frame therein.
