Dry wall extrusion grille

Abstract

A dry wall extrusion grille comprising a frame, a liner bar grille, sheet rock screws, pre-perforated through holes, indented slots, and a flexible edge.

Claims

1. A dry wall extrusion grille comprising: a frame, a linear bar grille located in said frame comprised of vanes and cross members that direct a flow of air, pre-perforated through holes, indented slots, and a flexible mounting flange located between a top and bottom edge of the frame and extending outwardly from said frame; said indented slots defined as small recesses in said flexible mounting flange that receive plaster, joint compound or mud, said pre-perforated through holes located in the flexible mounting flange.

2. The extrusion grille of claim 1 wherein said flexible mounting flange is fastened to a wall or ceiling with said pre-perforated through holes.

3. The extrusion grille of claim 1 further comprising sheet rock screws.

4. The extrusion grille of claim 3 wherein said frame is installed with said sheet rock screw before plaster or a joint compound is applied.

5. The extrusion grille of claim 4 wherein said extrusion grille is installed to a wall with four sheet rock screws.

6. The extrusion grille of claim 1 wherein said frame is constructed of four mitered pieces welded together.

7. The extrusion grille of claim 1 wherein said pre-perforated mounting through holes provide multiple mounting options to address multiple field conditions.

8. The extrusion grille of claim 1 wherein said extrusion grille is a fully welded construction.

9. The extrusion grille of claim 1 wherein said extrusion grille comprises multiple, pre-punched mounting holes for fastening in a wide range of wall conditions and materials.

10. The extrusion grille of claim 1 wherein said extrusion grille comprises multiple, pre-punched mounting holes for attachment to underlying studs (support beams).

11. The extrusion grille of claim 1 wherein said extrusion grille comprises pre-punched holes accurately sized for standard wall board/sheet rock screws so no special hardware or tools are required.

12. The extrusion grille of claim 1 wherein said flexible mounting flange fastens said extrusion grille to uneven wall surfaces.

13. The extrusion grille of claim 1 wherein inside of said extrusion grille frame extends about ¾″ deep into opening so that said extrusion grille is installed in a wall board or plaster ranging from about ¼″ thru about ¾″ thick.

14. The extrusion grille of claim 1 wherein said extrusion grille allows an installer to cut a rough hole in a wall and slip said extrusion grille frame into said hole.

15. The extrusion grille of claim 1 wherein no routing or recessed cut is necessary.

16. The extrusion grille of claim 1 wherein there is no blocking or added wood necessary for attachment to wall.

17. The extrusion grille of claim 1 wherein said extrusion grille is comprised of aluminum material.

18. The extrusion grille of claim 1 wherein said extrusion grille is used with a fixed core, a core welded directly to said frame or removable core for access to controls or filtration behind said grille.

19. The extrusion grille of claim 1 wherein said extrusion grille is mounted, so that said entire frame and grille are flush to a wall providing a seamless installation.

20. The extrusion grille of claim 1 wherein said extrusion grille is mounted in only one way, so that it cannot be installed backward.

21. The extrusion grille of claim 1 wherein said extrusion grille has a special angled edge that provides a step for a standard spackle knife to rest when a plaster or joint compound is being applied.

22. The extrusion grille of claim 1 wherein said extrusion grille has a special angled edge that provide a crisp, clean line set up for application of final skim coat of plaster (joint compound).

23. The extrusion grille of claim 1 wherein said extrusion grille is flush mounted to a wall without requiring a stud.

DETAILED DESCRIPTION OF THE INVENTION

(7) FIG. 1 shows the frame 10 comprising four mitered pieces 12, 14, 16 and 18, which are welded at 20, 22, 24, and 26. FIG. 2 shows the bottom view of frame 10 of FIG. 1.

(8) FIGS. 3 and 4 show the extrusion grille 30, which comprises a linear bar grille 32. The extrusion grille 30 has an aluminum profile 34, a flexible mounting flange 36 that is used for fastening to a wall or ceiling with perforated through holes 40. The extrusion grille 30 further comprises indented slots 38 used to capture joint compound or plaster 42.

(9) Extrusion grille 30 further comprises a special angled edge 44 to create a step for a spackling knife to use as a straight edge. A common sheet rock screw 46 is threaded into the wall material.

(10) FIG. 5 shows the extrusion grille 30 having the linear bar grille, a standard sheet rock screw 46, and pre-perforated mounting through holes that provide many mounting options to address multiple field conditions.

(11) FIG. 6 shows the extrusion grille 30 installed after the plaster or joint compound is applied. The frame 10 is installed with the sheet rock screw 46 before plaster or joint compound is applied.
