[0028] Referring now to
[0029] The upper subassembly D also includes a male die punch 4 mounted on the lower ends of posts 5, the upper ends of which are secured to an upper handle 6. Posts 5 are slidably received by holes in plate 3 as shown, so that the plate 3 and the punch 4 are movable between up and down positions. Compression springs 7 are provided around posts 5 between plate 3 and handle 6 so that the punch 4 is normally biased upwardly towards an up, disengaged position within a corresponding complementary opening through plate 1 as shown.
[0030] Body 1 and plate 3 can be formed of any suitable material, such as metal or plastic. Punch 4 can be formed of metal, such as hardened steel. In the preferred embodiment, punch 4 is rectangular, as shown, but could also be square, circular, or oval if desired, with the hole in body 1 being of similar, complementary size and shape.
[0031] The lower surface of punch 4 is recessed with a raised sharp peripheral edge so as to cut a clean hole B in gutter C when punch A is actuated.
[0032] The lower subassembly E includes a hollow body 8 and a female die plate 9 that fits into a recess in the bottom surface of the body 8, which are secured together with screws or other suitable fasteners (not shown). As will be discussed later, a pilot hole is formed in gutter C prior to positioning upper subassembly D in gutter C and positioning lower assembly E below gutter C. Shaft 11 is positioned through the pilot hole to facilitate positioning of hole punch A in gutter C. A raised lip 12 is preferably provided along one edge of body 8 to facilitate accurate rotational positioning of the punch A in the rain gutter C, as best seen in
[0033] The female die plate 9 includes a central opening corresponding in shape and size to punch 4. In the preferred embodiment, the opening in plate 9 is rectangular, as shown, but could also be square, oval, or circular if desired.
[0034] The lower subassembly E also includes a shaft 11 threadedly secured at its lower end to a lower handle 10. Standoff posts 15 are threadedly secured between handle 10 and die plate 9, so that the upper end of the shaft 11 extends upwardly through the central openings in die plate 9 and body 8. When in use, shaft 11 will extend through a pilot hole in the gutter to facilitate the positioning of the hole punch.
[0035] Body 8 can be formed of any suitable material, such as metal or plastic. Die plate 9 can be formed of metal, such as hardened steel. In the preferred embodiment, die plate 9 includes an opening that corresponds and is complementary with the male punch 4 for cutting a hole B of the desired size and shape. For example, the male punch 4 and female die plate 9 can be dimensioned to cut a 2×2, 2×3, 3×3, 3×4 or 4×4 inch size hole B in gutter C.
[0036] Magnets 2 are preferably located in recesses in the opposing surfaces of bodies 1 and 8, as shown, the upper and lower subassemblies for releasably retaining D and E together when positioning punch A in gutter C for actuation. In some embodiments, only one of bodies 1 and 8 have magnets; the other can be constructed of magnetic material.
[0037] Outlet hole B is formed as follows. A pilot hole is first made in the bottom of gutter C in about the middle of the desired location of the outlet hole B to be formed, using a drill or a small electric hole saw. In some embodiments, a step bit is used. In some embodiments the upper subassembly D of gutter punch A can be used as a guide or template for making the pilot hole, by first positioning subassembly D inside the gutter at the desired location of outlet hole B along gutter C. A drill (not shown) is then passed through the center holes in the upper handle 6, plate 3, punch 4 and body 1 to form a pilot hole in the gutter C for receiving the shaft 11.
[0038] The lower subassembly E is then positioned underneath gutter C with shaft 11 extending upwardly through the pilot hole in gutter C and center holes in body 1, punch 4 and plate 3 of the upper subassembly D. With the upper and lower subassemblies D and E retained in position by magnets 2, cap screw or shoulder bolt 13 can then be passed through the center hole in the upper handle 6 and screwed into the upper end of shaft 11 to releasably interconnect the subassemblies. As bolt 13 is tightened, male die punch 4 is forced downwardly along shaft 11 and into female die plate 9 to make outlet hole B in the gutter C, with the cutout (not shown) then being captured on shaft 11. Unscrewing bolt 13 allows the upper and lower subassemblies D and E to be disconnected and separated so that gutter hole punch A can then be removed, and an outlet tube (not shown) installed in gutter C.
[0039] If desired, a set screw 14 can be provided in lower handle 10 to secure the lower end of shaft 11 against turning or loosening when turning bolt 13.
[0040] Although the male die punch 4 herein has been shown as being of rectangular shape with sharpened edges and raised, sharpened corners, it will be understood that other configurations could be used. The male die punch 4 and corresponding opening in plate 9 could be round or oval shaped, for example. Also, the die punch 4 could be configured with blades to make an X cut in gutter C.
[0041] Although gutter hole punch A has been shown in a lengthwise position within gutter C, it could also be adapted to fit sideways or crosswise therein, if desired.

[0046] Magnets 32 are preferably located in recesses in the opposing surfaces of guides 31 and 42, as shown, for releasably retaining the upper and lower subassemblies G and H together when positioning punch F in gutter C. In some embodiments, only one of guides 31 and 42 have magnets or a magnetized material; the other is made of a magnetic material.
[0047] After the pilot hole has been formed in gutter C and the upper and lower bodies or subassemblies G and H have been positioned in the gutter C with shaft 46 extending upwardly through the hollow shaft of sleeve 38, the cap screw or bolt 47 can be inserted into the upper end of shaft 46 and tightened down to force male die punch 36 downwardly along the shaft and into female die plate 44 to make outlet hole B in the gutter C, with the cutout (not shown) then being captured on the shaft for removal afterwards along with gutter punch F.
[0048]
[0049] The die plate 44 is preferably square so that it will fit into guide plate 42 even after rotation by 90°. Two opposing pairs of guide holes are provided in plate 30 at right angles to each other, as shown, so that the punch F can be adjusted to make hole B either lengthwise or crosswise in gutter C. If desired, a hardened washer 53 and spacers 54 and be secured with screws 55 to the upper handle 40 to reduce wear on the upper end of sleeve 38 when bolt 47 is tightened.
[0050]
[0051]
[0052]
[0053] The lower subassembly H includes a hollow body or guide 42 and a female die plate 44 that fits into a recess in the top surface of the body 42. A raised lip 51 is preferably provided along one edge of guide 42 to facilitate accurate positioning of the punch F in the rain gutter C, as best seen in
[0054] While punch F has magnets 32 that are preferably located in the opposing surfaces of guides 31 and 42 for releasably retaining the upper and lower subassemblies G and H together when positioning punch F in gutter C, punch I has magnets and/or magnetized guides 31 and 42. Similar to the other embodiments, the magnetic force releasably connects upper and lower subassemblies G and H together when positioning punch I. In some embodiments of both Punches F and punch I, only guides 31 will have magnets or be magnetized. In this embodiment, guide 42 and/or die plate 44 will be constructed of steel or other material that is attracted to the magnetic force of guide 31. If other embodiments, only guide 42 and/or die plate 44 will contain magnets or be magnetized. In this embodiment, the magnetic force from guide 42 and/or die plate 44 will attract guides 31 which are constructed of steel or other magnetic material. In some embodiments, body 42 and guides 31 are constructed of plastic, with guides 31 have embedded magnets, and die plate 44 is made of a magnetic material such as metal. In this embodiment, the magnets in guides 31 are attracted to magnetic die plate 44.
[0055] One embodiment of the invention is a hole punch that can punch holes that are longer in either the longitudinal or cross dimension of a gutter C. Some punches will produce openings that are longer in one dimension than the other dimension; for example, 2×3 inches or 3×4 inches. As used herein, an A-cut is when the longer dimension is aligned with the longitudinal axis of the gutter C. A B-cut is when the shorter dimension is aligned with the longitudinal axis of the gutter C. As shown in
[0056] Some gutters, such as those sold under the trademark Leaf Guard™, do not have an open top as is shown with gutter C in
[0057] The lower subassembly K includes a hollow body or guide 42 and a female die plate 44 that fits into a recess in the top surface of the body 42. A raised lip 51 is preferably provided along one edge of guide 42 to facilitate accurate positioning of the punch L in the rain gutter C′, as best seen in
[0058]
[0059] In another embodiment of punch L, the interior of shaft 71 is threaded. In this embodiment, if bolt 72 comprises and unthreaded section with a diameter smaller than the threaded section, bolt 72 can be threaded through shaft 71 so that it can freely move upward but, due to the threads of the bolt and shaft, it cannot move downward except through rotation. This feature helps prevent the user from dropping bolt 72 during assembly of punch L. After the top and bottom assemblies, J and K, are positioned, upward movement of bolt 72 will cause the end of the bolt to move through the opening of guide 44 and toward or through the pilot hole in gutter C′. Once the tip of bolt 72 engages shaft 38, the user can rotate bolt 38 to effect the punching.
[0060] In the embodiments discussed herein, some or all of the surfaces of the various punches that touch the gutter can be treated with Plasti Dip™ or other similar rubberized or plasticized coating to prevent the punch from scratching the gutters. For punch L, handle 33 can likewise be coated. In other embodiments, the pieces of the punch that touch the gutter can be made of plastic. In the event that the plastic pieces need to be magnetized, magnets can be embedded in the plastic.
