DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings and first to FIG. 1, there is shown a tool 20 for removing cedar roofing material, in this example cedar shingles 22, seen in FIG. 8. The tool may also be used for removing cedar shakes, for example. The tool has a proximal end 24 and a distal end 26 which is spaced-apart from its proximal end.
The tool 20 has a handle 28 that is rectangular in cross-section in this example and formed of square-tubing, though this is not strictly required. The handle has a first end 30 and a second end 32 which is spaced-apart from its first end by a first distance or longitudinal length Lh seen in FIGS. 2 and 3. The first end of the handle is located adjacent to the proximal end 24 of the tool 20. The second end 32 of the handle 28 is inclined, as seen best in FIG. 3, and faces in the direction of distal end 26 of the tool 20 in this example. The handle has a top 34 and a bottom 36 which is spaced-apart from its top. A pair of spaced-apart sides 38 and 39, as seen in FIGS. 4 and 5, extends between the top and bottom of the handle 28. The top, bottom and sides of handle 28 are rectangular in shape in this example. As seen in FIGS. 4 and 5, the handle has a width Wh between its sides 38 and 39. The top 34, bottom 36 and sides of the handle 28 extend from first end 30 to second end 32 of the handle 28.
The tool 20 includes a gripping member 40 which connects to and extends from the first end 30 of the handle 28 in this example. The gripping member aligns with and extends along the proximal end 24 of the tool 20 in this example. The gripping member 40 is cylindrical in shape in this example. The gripping member and the handle 28 connect together via welding in this case, though this is not strictly required. The gripping member 40 extends substantially perpendicular from the handle 28 in this example, extending from the bottom 36 of the handle. The gripping member includes an elastomeric tubing 42 which extends therearound for facilitating gripping with a worker's hand, such as hand 94 of worker 92 seen in FIG. 12.
Referring to FIG. 1, the tool 20 has a blade 44 which is concavely curved at its top 52, as seen in FIG. 2 and convexly curved at its bottom 54, best seen in FIG. 3.
The blade is elongate, thin, and substantially rectangular in shape in this example as shown in FIG. 1. The blade 44 includes an angled base portion 46 which connects to the inclined second end 32 of the handle 28 and extends to distal end 26 of the tool. The blade also includes a proximal end 48 which is adjacent to the base portion, and a distal end 50 which is spaced-apart from the base portion and the proximal end of the blade.
Referring to FIG. 2, base portion 46 of the blade 44 is angled relative to the proximal end of the blade by angle α that is obtuse. Angle α is equal to an angle within the range of 110 to 140 degrees according to one preferred example, and is substantially equal to 125 degrees according to a further preferred example, though this is not strictly required.
The distal end 50 of the blade 44 is tapered and coincides with the distal end 26 of the tool in this example. As seen in FIG. 3, the proximal end 48 of the blade aligns with and extends from the bottom 36 of handle 28. The blade is arcuate-shaped between its proximal end 48 and its distal end 50. The blade 44 has a curvature with a radius within the range of thirty-eight to forty-four inches according to one preferred example, and is substantially equal to forty-two inches according to a further preferred example, though this is not strictly required.
As seen in FIGS. 2 and 3, distal end 50 of the blade is spaced-apart from proximal end 48 of the blade by a second distance or longitudinal length Lb. The length of the blade is longer than the length Lh of the handle 28. In this example, the length of the blade is substantially twice as long as the length of the handle.
The blade 44 includes a pair of spaced-apart, arcuate-shaped side edge portions 56 and 58 as seen in FIG. 1. Referring to FIGS. 2 and 3, the side edge portions of the blade extend between the top 52 and bottom 54 of the blade. The top and bottom of the blade 44 are rectangular in this example as seen in FIGS. 4 and 5, respectively. Referring to FIG. 1, the top 52, bottom 54, and side edge portions 56 and 58 of the blade extend between the proximal end 48 and distal end 50 of the blade. As seen in FIGS. 4 and 5, the blade has a width Wb between its side edge portions. The blade 44 extends laterally outwards relative to handle 28, with its width Wb being larger than the width Wh of the handle in this example.
Tool 20 is used to remove cedar shingles 22 in this example from a roof 60, as seen in FIG. 8. The roof has a plurality of spaced-apart rafters, as shown by rafters 62 and 64, which extend downwards in a vertical direction at least in part. Adjacent rafters are spaced-apart by a distance Dr. The distance between adjacent rafters 62 and 64 may be substantially equal to a spacing in the range of sixteen to twenty-four inches, according to North American building codes. The length Lb of the blade 44 seen in FIGS. 2 and 3 is equal to or greater than the maximum distance between adjacent rafters 62 and 64. In this example, the length of the blade is equal to or greater than twenty-four inches.
Referring back to FIG. 8, the roof 60 includes a plurality of spaced-apart roof strapping, as shown by strapping 66 and 68, which extends in a substantially horizontal direction. The strapping connects to and extends perpendicular to the rafters 62 and 64 via fasteners, in this example respective pairs of nails, shown by nails 71 and 73, which are hammered through the strapping and into the rafters. Adjacent lengths of strapping 66 and 68 are spaced-apart from each other by a distance Ds. The distance between adjacent strapping may be substantially equal to two to four inches, according to North American building codes. The width Wb of the blade 44 seen in FIGS. 4 and 5 is equal to or less than the distance between adjacent roof strapping 66 and 68. In this example, the width of the blade is substantially equal to or less than two inches.
The roof 60 includes a plurality of rows 72, 74, 76, 78 and 80 of overlapping cedar shingles connecting to the strapping 66 and 68 via fasteners in this example pairs nails 75 and 77 which extend through the shingles and into the strapping. The roof includes a plurality of courses of shingles, where each course comprises two or more shingles aligned in a row along a given length portion of strapping and overlayed at least in part between respective ones of the rafters 62 and 64, as shown by course 82 of shingles 84, 86 and 88 aligning therealong. Blade 44, seen in FIG. 1, is shaped to extend across and remove one course 82 of shingles at a time. As seen in FIG. 8, each of cedar shingles has an average width Wc. Length Lb of the blade 44, seen in FIGS. 2 and 3, is greater than the average width of two of the cedar shingles. Roofing felt 90 is interposed between the strapping 66 and 68 and shingles 22. Cedar roofs 60 per se, including their various parts such as rafters 62 and 64, strapping 66 and 68, and cedar roofing material and their various functionings, are well known to those skilled in the art and therefore will not be described in further detail.
FIGS. 9 to 12 show tool 20 in use. Referring first to FIG. 9, worker 92 grips the tool 20 with one hand 94 on gripping member 40 or, in this example, by holding handle 28 adjacent to end 30. The worker's other hand 96 may grip the tool by the handle adjacent to its end 32 or, in this example, by initially holding blade 44 adjacent to its end 48.
Distal end 26 of the tool 20 is inserted between respective lengths of the strapping 66 and 68 within the spacing extending between distance Ds. The tool may be inserted between respective ones of the strapping at a location adjacent to a first one of the rafters 62 seen in FIG. 8. As the tool 20 is inserted within this spacing, it may avoid hitting nails 75 and 77, seen in FIG. 8 extending through the shingles and extending through the strapping, because of the elongate, slender shape of the blade 44. Referring to FIG. 10, the tool is then further inserted and lowered towards the strapping 66 and 68 until the distal end 50 of the blade, seen in FIG. 1, abuts a second one of the rafters 64 seen in FIG. 8. When this occurs, gripping member 40 may be in a substantially vertical position as seen in FIG. 10. According to one example, the blade 44 penetrates rafter 64 with its tapered distal end 50. At this stage, the blade extends across two or more cedar shingles.
Thereafter, the tool 20 is raised upwards as shown by arrow 98 in FIG. 11 via handle 28. According to one example, the worker 92 uses the tapered distal end 50 of the tool, seen in FIG. 1, as a pivot point for raising the tool upwards. As seen in FIG. 12, the blade 44 abuts the cedar shingles 84, 86 and 88 in its path, which are raised upwards and removed from their strapping 68. According to one embodiment, the tool 20 is raised until the gripping member 40 is in a substantially horizontal position.
During this process, the angled base portion 46 of the blade 44 abuts at least some of the cedar shingles 84, 86 and 88 so raised and removed, as seen in FIG. 12. This causes the cedar shingles so raised and removed to tumble forwards, as shown by arrow 100, towards further cedar shingles yet to be removed.
It will be appreciated that many variations are possible within the scope of the invention described herein. Cedar shingles have been described herein. However, the tool 20 may also be used to remove other cedar roofing material, such as cedar shakes. It will be further understood by someone skilled in the art that many of the details provided above are by way of example only and are not intended to limit the scope of the invention which is to be determined with reference to at least the following claims.
