The disclosure and prior art relates to tools utilized for removing framing, wall structures, decking and the like and more particularly pertains to a construction wrecking tool for assisting a person in pulling apart structures typically held together by nails and other like fasteners.
An embodiment of the disclosure meets the needs presented above by generally comprising a plate that is elongated and has a first end, a second end, a first lateral edge, a second lateral edge, an upper surface and a lower surface. The plate includes a claw section, a chisel section and a middle section positioned between the claw and chisel sections. The claw section includes the first end and the chisel section includes the second end and a rounded heel. The claw section includes a first portion and a second portion. The first portion is attached to the middle section and curves upwardly and away from the middle section in a semi-cylindrical shape to form the rounded heel. The second portion extends downwardly from the first portion. The chisel section is angled upwardly from the middle section. The upper surface has an elongated crest therein that is spaced from the first and second lateral edges and extends along a length of the middle section and into the chisel section.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
The claw section 26 includes the first end 14 and the chisel section 28 includes the second end 16. Moreover, as may typically be found on a pry bar, the claw section 26 may include a rounded heel 32. The middle section 30 may be substantially straight from the chisel section 28 to the claw section 26 such that the first 18 and second 20 lateral edges of the middle section 30 lie in a shared horizontal plane.
The claw section 26 includes a first portion 34 and a second portion 36. The first portion 34 is attached to the middle section 30 and curves upwardly and away from the middle section 30 in a semi-cylindrical shape to form the rounded heel 32. The second portion 36 extends downwardly from the first portion 34 such that the shared horizontal plane 38 of the middle section 30 intersects the second portion 36. The second portion 36 lies in a plane 40 orientated perpendicular to the shared horizontal plane 38.
The second portion 36 of the claw section 26 has an aperture 42 extending therethrough. The aperture 42 has an upper edge 44, a lower edge 46, a first side edge 48 and a second side edge 50. A pry panel 52 is integrally attached to and extends between the upper 44 and lower 46 edges. The pry panel 52 is bowed inwardly toward the second end 16. More particularly, the pry panel 52 may form a triangle wherein the pry panel 52 forms two legs and the third leg is a plane of the aperture 42. The pry panel 52 includes a short leg 54 and a long leg 56 where the short leg 54 is positioned nearer to the first portion 34. The long leg 56 may form an angle with a plane of the aperture 42 between 20° and 25° while the short leg 54 may form an angle with the plane of the aperture 42 between 40° and 50°. The aperture is generally rectangular shaped and may have a length and a width each between 2.0 inches and 4.0 inches.
The chisel section 28 is angled upwardly from the middle section 30. More specifically, the chisel section 28, from the middle section 30 to the second end 16, is angled upwardly to form an angle 56 between about 20° and 30° with respect to the shared plane 38. This will provide more leverage when the chisel section 28 is used to remove fasteners or is to be extended between two structural components typically held together by nails, screws and the like.
The first end 14 is tapered to a sharpened edge wherein the lower surface 24 adjacent to the first end 14 is angled toward the upper surface 22. A notch 58 extends into the first end 14 and is positioned between the first 18 and second 20 lateral edges. The second end 16 is tapered to a sharpened edge wherein the upper surface 22 adjacent to the second end 16 is angled toward the lower surface 24. A notch 60 extends into the second end 16 and is positioned between the first 18 and second 20 lateral edges. The notch 58 in the first end 14 and the notch 60 in the second end 16 are each V-shaped and form angles between 15° and 25°. Each of the first 14 and second 16 ends forms an angle being between about 15° and 25°.
The claw section 26 has a pair of indentations 62 therein extending into the upper surface 22 which causes bowing outwardly of corresponding areas in the lower surface 24. The indentations 62 are laterally spaced from each other. The indentations are positioned 62 in the second portion 36, opposite the first edge 14 and adjacent to the heel 32. The upper surface 22 of the claw section 26 includes a pair of ridges 64 that are laterally spaced from each other and are positioned in the first portion 34. The ridges 64 cause corresponding depressions on the lower surface as can be seen in
In use, the pry bar assembly 10 is used in a conventional manner for removing fasteners, such as nails, and for pulling apart structural components and thus act as a “wrecking” tool for deconstruction purposes. However, the unique shape of the assembly 10 provides for greater strength as the plate 12 will not easily bend while being used. This allows the assembly 10 to be more light weight and have a thickness of less than 0.17 inches.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
