Description of the Preferred Embodiments
Generally, elevated outer hearths are constructed of materials such as stone, brick, rock, ceramic tile and the like. In certain instances, a hearth constructed of these materials is found to include one or more acute protruding edges. Hearths of this design, while presenting an attractive and decorative appearance, also present an insidious threat of injury to persons falling against or otherwise forcefully contacting one of the outer hearth edges.
The present invention not only reduces the chance of serious injury to persons contacting an outer hearth edge, but may also provide a comfortable surface to lean or sit upon. The present invention may also be provided with a complementing, decorative covering which may be aesthetically enhancing in some applications.
As shown in FIG. 1, and described herein by the general reference numeral 10, is an outer hearth pad constructed in accordance with the present invention and secured to an outer hearth 12. The outer hearth 12 comprises an elevated top surface 14 extending generally in a horizontal plane and a horizontally extending elevated edge 16 formed by the intersection of a side surface 18 and the top surface 14. The elevated edge 16 comprises a front elevated edge 20 formed by the intersection of a front side surface 22 having opposite ends 23 and 24 and the elevated top surface 14. The elevated edge 16 also comprises a first end elevated edge 25 formed by the intersection of a first end side surface 26 with the elevated top surface 14. The elevated edge 16 further comprises a second end elevated edge 28 formed by the intersection of a second end side surface 29 with the elevated top surface 14.
A first vertical edge 32 is formed by the intersection of the first end side surface 26 with end 23 of the front side surface 22. First vertical edge 32 extends upwardly and intersects the elevated edge 16 forming a first elevated corner (not shown) of the outer hearth. A second vertical edge 34 is formed by the intersection of the second end side surface 29 with end 24 of the front side surface 22. The second vertical edge 34 extends upwardly and intersects the elevated edge 16 forming a second elevated corner (not shown) of the outer hearth 12.
