Fireplace screen
View Patent ↗A fireplace screen comprising a mesh structure positionable about an outer surface of a fireplace opening. The mesh structure is shaped to cover the fireplace opening. Holes in the mesh structure are configured to promote an inflow of air external to a fireplace through the mesh structure and a vertical circulation of the air across an interior planar surface of the mesh structure located outside of the fireplace opening.
1. A fireplace screen, comprising:
a mesh structure positionable about an outer surface of a fireplace opening, wherein the mesh structure is shaped to cover the fireplace opening, and, holes in the mesh structure are configured to promote an inflow of air external to a fireplace through the mesh structure and a vertical circulation of the air across an interior planar surface of the mesh structure located outside of the fireplace opening and wherein a total number of openings per unit area of a central planar surface of the mesh structure is different for different regions of the central planar surface.
2. The screen of claim 1 , wherein the mesh structure is attached to a frame defining the outer surface of the fireplace opening.
3. The screen of claim 1 , wherein the fireplace opening is covered by a transparent panel and the mesh structure is attached to one or more edges of the transparent panel so as to locate the mesh structure outside of the fireplace opening.
4. The screen of claim 3 , wherein one or more ends of the mesh structure are bent such that a central planar surface of the mesh structure is offset from a parallel planar surface of the transparent panel when the mesh structure is attached to the transparent panel.
5. The screen of claim 4 , wherein a distance of the offset is at least about ⅛ of an inch.
6. The screen of claim 4 , wherein the mesh structure is attached to the transparent panel such that a pull force or a push force of up to 5 pounds not dislodge the mesh structure from its attachment points.
7. The screen of claim 3 , wherein one or more bent ends of the mesh structure forms the interior surface as a beveled surface that has an incident angle to the planar surface of the transparent panel.
8. The screen of claim 3 , wherein a bend in a top end of the mesh structure forms a hook that is configured to fit over an upper edge of the transparent panel so that the mesh structure hangs on the transparent panel and a bend in a bottom end of the mesh structure forms a clasp that is configured to fit over a lower edge of the transparent panel.
9. The screen of claim 4 , wherein a bend in a top end or bottom end of the mesh structure forms a flange that is configured to fit into one or more notches located in an edge of a frame of the fireplace opening.
10. The screen of claim 1 , wherein the holes in the mesh are distributed over the entire surface of the mesh structure.
11. The screen of claim 1 , wherein the holes in the mesh structure occupy about 30 percent to about 80 percent of a total surface area of the mesh structure.
12. The screen of claim 1 , wherein the holes in the mesh structure occupy an area in a range of about 50 to 70 percent of an total surface area of the mesh structure.
13. The screen of claim 1 , wherein the mesh structure is coated with a urethane-based thermally insulating material.
14. The screen of claim 1 , wherein the screen is a frameless unitary body of the mesh structure.
15. A fireplace, comprising:
a fireplace housing having a base;
a flame element located on the base and viewable through an opening of the fireplace housing; and
a fireplace screen that includes a mesh structure, wherein the mesh structure is shaped to cover the opening, and holes in the mesh are configured to promote the inflow of air external to the fireplace housing through the mesh, and a vertical circulation of the air across an interior planar surface of the mesh located outside of the fireplace opening and wherein a total number of openings per unit area of a central planar surface of the mesh structure is different for different regions of the central planar surface.
16. The fireplace of claim 15 , wherein an entire outer surface of the mesh structure is at or below a target thermesthesiometer reading equal to or less than 60° C. when the flame element is generating heat.
17. The screen of claim 1 , wherein the total number of openings per unit area in a lower one-third of the central planar surface is greater than the total number of openings per unit area in a upper two thirds of the central planar surface.
18. The screen of claim 1 , wherein a top outer surface of the mesh is beveled relative to the central planar surface of the mesh structure.
19. The fireplace of claim 13 , wherein the total number of openings per unit area in a lower one-third of the central planar surface is greater than the total number of openings per unit area in a upper two thirds of the central planar surface.
20. The fireplace of claim 13 , wherein a top outer surface of the mesh is beveled relative to the central planar surface of the mesh structure.
