Description

The exemplary embodiments of present invention relate generally to roofing construction tools and, more specifically, to a weight-bearing, compressible roofing construction tool and methods thereof.

BACKGROUND OF THE DISCLOSURE

Sloped roofs present problems for workers working on the roofs as well as for roofing materials, e.g., shingles, tools and the like, that are not attached to the roofs. More particularly, workers and roofing materials can slide along a sloped roof and possibly fall from the roof. In order to minimize sliding of workers on sloped roofs, workers often wear boots having high coefficient of friction materials provided on the soles of their boots. While this may reduce slippage of workers on sloped roofs, it doesn't always protect workers from sliding.

BRIEF SUMMARY OF THE DISCLOSURE

In accordance with an exemplary embodiment there is provided a roofing construction tool comprising a substantially planar stand comprising a compressible material that includes a top surface having a first area, a bottom surface defining a second area larger than the first area, and side walls joining the top surface and bottom surface.

An aspect of the exemplary embodiment is that the side walls taper and slope downwardly from the top surface to the bottom surface. The top surface can have a length and a width of about 2 feet to about 5 feet. The top and bottom surfaces can be substantially square, substantially rectangular, or substantially octagonal in shape. The stand can have a height between the top surface and bottom surface of about 6 inches to about 14 inches.

Another aspect of the exemplary embodiment is that the compressible material can comprise at least one of open cell rubber, sponge rubber, neoprene rubber, ethylene propylene diene monomer (EDPM) rubber, styrene-butadiene (SB) rubber, Buna-N rubber, natural gum rubber, natural latex rubber, fluoroelastomer (FKM) rubber, butyl rubber, epichlorohydrin (ECH) rubber, ethylene-vinyl acetate foam, low-density polyethylene foam, expanded polypropylene, polyurethane foam, polyvinyl chloride foam, and silicone foam. The compressible material can have a density from about 1 pound per cubic foot to about 6 pounds per cubic foot.

Another aspect of the exemplary embodiment is that the roofing construction tool can comprise a high friction layer adjacent the bottom surface. The high friction layer can be about 0.5 to about 3 inches in thickness and can include a plurality of through holes. The high friction layer can comprise at least one of latex, nitrile rubber, double-density polyurethane, thermoplastic rubber, thermoplastic polyurethane, styrene rubber, rubber and glass fiber mixture, crepe rubber, microcellular polyurethane, and ethylene vinyl acetate.

Another aspect of the exemplary embodiment is that the roofing construction tool can include at least one weight embedded therein having a density greater than a density of the compressible material.

In accordance with the exemplary embodiments, there is provided an aerodynamic roofing construction tool that is resistant to movement on a roof surface even in the presence of high winds.

According to an aspect, the side walls 106 taper from the top surface 102 to the bottom surface 104. In particular, the side walls slope downwardly from the top surface to the bottom surface. The slope may be constant, as shown in FIG. 2, or variable, e.g., concave (FIG. 4), for beneficial aerodynamic effect.

According to an aspect, the top surface 102 has a length “L₁” of about 2, 3, 4, or 5 feet and a width “W₁” of about 2, 3, 4, or 5 feet. The bottom surface 104 has a length “L₂” greater than L₁ and a width “W₂” greater than W₁ which depend on the degree of slope of the side walls 106. The top surface 102 can have any suitable shape. For instance, the top surface can be, without limitation, substantially square as shown in FIG. 1, substantially rectangular, or substantially octagonal as shown in FIG. 3. Likewise, the bottom surface 104 can have any suitable shape. For instance, the top surface can be, without limitation, substantially square as shown in FIG. 1, substantially rectangular, or substantially octagonal as shown in FIG. 3. The stand 101 can have a height “H” (FIG. 2) between the top surface 102 and the bottom surface 104 of about 6, 7, 8, 9, 10, 11, 12, 13 or 14 inches.

Referring to FIGS. 3 and 4, there is shown a roofing construction tool 200 in accordance with another exemplary embodiment of the present disclosure. The roofing construction tool 200 comprises a substantially planar stand 201 comprising a compressible material that includes a top surface 202 having a first area, a bottom surface 204 defining a second area larger than the first area, and side walls 206 joining the top surface and bottom surface. According to an aspect, the side walls 206 taper from the top surface 202 to the bottom surface 204. In particular, the side walls slope downwardly from the top surface to the bottom surface.

According to an aspect, the top surface 202 has a length “L₁” of about 2, 3, 4, or 5 feet and a width “W₁′” of about 2, 3, 4 or 5 feet. The bottom surface 204 has a length “L₂′” greater than L₁′ and a width “W₂′” greater than W₁′ which depend on the degree of slope of the side walls 206. The top surface 202 can have any suitable shape. For instance, the top surface can be, without limitation, substantially square as shown in FIG. 1, substantially rectangular, or substantially octagonal as shown in FIG. 3. Likewise, the bottom surface 204 can have any suitable shape. For instance, the top surface can be, without limitation, substantially square as shown in FIG. 1, substantially rectangular, or substantially octagonal as shown in FIG. 3. The stand 201 can have a height “H₁” (FIG. 4) between the top surface 202 and the bottom surface 204 of about 6, 7, 8, 9, 10, 11, 12, 13, or 14 inches.

FIG. 4 additionally shows that the roofing construction tool 200 can further comprise a high friction layer 208 adjacent the bottom surface 204. The high friction layer 208 can have a thickness or height “H₂” of about 0.5, 0.75, 1, 1.5, 2, 2.5 or 3 inches. Together, H₁ and H₂ form the total thickness “H′” of the roofing construction tool 200. In order to increase its slip-resistant characteristics, the high friction layer can include a plurality of through holes 210. The high friction layer can comprise at least one of latex, a rubber, such as nitrile rubber, thermoplastic rubber, styrene rubber, crepe rubber, rubber and glass fiber mixture, a polymer, such as thermoplastic polyurethane, microcellular polyurethane, ethylene vinyl acetate, and combinations thereof.

The compressible material that forms the stand 101 and the stand 201 can comprise at least one of a rubber, such as open cell rubber, sponge rubber, neoprene rubber, ethylene propylene diene monomer (EDPM) rubber, styrene-butadiene (SB) rubber, Buna-N rubber, natural gum rubber, natural latex rubber, fluoroelastomer (FKM) rubber, butyl rubber, epichlorohydrin (ECH) rubber, and a foam, such as ethylene-vinyl acetate foam, low-density polyethylene foam, expanded polypropylene, polyurethane foam, polyvinyl chloride foam, and silicone foam, and combinations thereof. The compressible material of stands 101 and 201 can also have a density from about 1, 2, 3, 4, 5, or 6 pounds per cubic foot or variable density throughout. For example, the roofing construction tool can have a higher density about its perimeter 209 and a lower density towards its center 207 as depicted schematically in FIG. 4 by dashed density demarcation line 211.

In order to enhance slip-resistance, the roofing construction tool 100 or 200 can include at least one weight 212 (FIG. 4) embedded therein having a density greater than a density of the compressible material, or a plurality of weights embedded throughout the stand.
