Abstract:
An extractable construction staple device particularly usable for removably fastening three-dimensional and planar workpieces to a substrate comprising:A. an insertion leg means adapted to be inserted downwardly into a substrate therebelow to facilitate securement of the construction staple with respect thereto;B. a retention biasing head means being responsive to insertion of said insertion leg means into the substrate to exert downwardly directed force against the substrate and any planar workpiece positioned thereon, said retention biasing head means also limiting the depth of penetration of said insertion leg means into the substrate;C. a retention arch means being arcuate in shape and extending upwardly away from said retention biasing head means to define a retention opening means thereunder to facilitate receiving of a three-dimensional workpiece therein positioned between said retention arch means and the substrate for retaining thereof, said retention biasing head means being responsive to insertion of said insertion leg means into the substrate with the exertion of force by said retention biasing head means downwardly toward the substrate to maintain said retention arch means spaced from the substrate to facilitate retaining of a workpiece therein; andD. an extraction arch means extending upwardly away from said retention biasing head means and said insertion leg means to define an extraction opening means thereunder to facilitate removal of the construction staple from the substrate, said retention biasing head means being responsive to insertion of said insertion leg means into the substrate with the exertion of force by said retention biasing head means downwardly against the substrate to maintain said extraction arch means spaced from the substrate in order to facilitate removal of the staple device from the substrate.
