DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a side view of the preferred embodiment 100 of the present flat lay-out tape. The tape 120 & 125 is preferably made of a resilient material, such as fiberglass and metal, that allows the tape to be durable and have a long useful life. The case 105 is also made of a durable material, such as a hard plastic, that is able to protect the invention from an advertent drop from a rooftop. A first set of indicator markings are provided on the top 120 of the tape, and a second set of indicator markings are provided on the back side 125 of the tape. The tape 120 & 125 is flat, and not beveled as are many measuring tapes, so the tape will lay flush with the roof surface. This allows roofers to hold a chalk line accurately to the indicator marks on the tape during the chalk line striking process and eliminates the need for making marks directly on the roof. Initially, the tape is coiled up inside of its case 105 and an eyelet 130 that is attached to the beginning end of the tape is all that is exposed. The roofer pulls out a desired length of the lay-out tape by pulling on the eyelet 130. The case 105 preferably includes a rewind coil that is attached to the interior end of the-tape. The rewind coil is tightened as the tape is pulled from the case 105 and provides a self-retracting feature to this embodiment 100. Self-retracting tapes are well-known in the art and further discussion of their mechanism is not required to understand the present invention. Sliding stop-lock 110 is provided on the case, above the exit area of the tape, to lock the tape in place and prevent retraction, when the roofer is using the architectural side 120 of the tape. Sliding stop-lock 115 is also provided to lock out the desired length of tape when the roofer is using the standard side of the tape.
FIG. 2 shows an alternative embodiment 200 of the present lay-out tape. The main features of the lay-out tape, such as the use of a flat, vice beveled, tape and indicators markings for different shingles on different sides 120 & 125 of the tape, are still present in this alternative embodiment 200. Also, an eyelet 130 is provided to secure the beginning end of the tape to the roof. However, in this embodiment 200, after the roofer has finished using the tape, the roofer uses a handle 210 to wind the tape back into the case 105.
FIG. 3 is a top view of the preferred embodiment 100 with the architectural side 120 of the lay-out tape facing upward. In practice, the roofer starts near the bottom of the roof, at a defined distance from the side edge of the roof, and makes one mark on the roof approximately 12 inches from the bottom of the roof. This will be the starting point for the first row of shingles and is the only mark the roofer needs to make on the roof surface, using the present invention. The roofer then lines up the first indicator 300 on the lay-out tape with the one manual mark on the roof and tacks the eyelet 130 down to secure the position of the tape. Since architectural shingles are 13 ¼ inches long, starting the first row at 12 inches from the bottom allows for a 1 ¼ inch overhang of the first row of shingles. Of course, smaller and larger overhangs may also be used. The roofer then extends the lay-out tape up to the apex of the roof and temporarily secures the outstretched tape over the apex of the roof by sliding the stop-lock 110 down and allowing the weight of the case 105 to be pulled down the other side of the roof. Of course a hammer or other object can also be used to further secure the case 105. To insure straight rows, the case 105 should be the same defined distance away from the side edge of the roof as the eyelet 125. Each of the row indicators 305 are spaced 5 ½ inches away from others on the architectural side 120 of the tape. The roofer then repeats these steps at the opposite end of the roof with a second lay-out tape. When both tapes are in place a chalk line can be stretched and “struck” between each of the corresponding row indicators 305 to quickly produce straight lay-out lines for each row of shingles. This process is discussed further below and illustrated in FIG. 7.
FIG. 4 is a top view of the preferred embodiment 100 wherein the lay-out tape has been flipped upside-down so that the standard side 125 is facing upward. The standard side 125 of the lay-out tape is used when standard shingles are being attached to the roof. Standard sized shingles are slightly smaller than architectural shingles and the row indicators 405 on the standard side 125 of the tape are accordingly closer together, in this example the row indicators are spaced 5 inches apart. The standard side 125 of the lay-out tape is used in the same fashion as with the architectural side 120, described above. By providing the indicia for standard shingles and architectural shingles on the opposite sides of the same tape, confusion over which indicator to follow is avoided. In the preferred embodiment 100, at least one side of the tape includes standard tape measure indicia, which eliminates the need to carry around a separate standard measuring tape. In this example, the standard side 125 of the present lay-out tape 100 includes the inch, foot and other markings found on a standard measuring tape. These standard measuring tape indicia can be used to measure the desired distance from the bottom of the roof, and make the one and only hand drawn mark on the roof that is required when using the present invention.
FIG. 5 is a top view of another alternative embodiment 500 with the architectural side of the tape facing up. As with the preferred embodiment, indicators for standard shingles are provided on the back side of the tape. In this embodiment 500, the first 2 inches 520 of the tape includes standard ¼ inch indicators, which allows the roofer to measure the amount of overhang of the first row of shingles. The largest indicator 510 on the tape is 13 ¼ inch away from the leading edge of the tape. After the desired amount of overhang has been measured, the roofer makes a single mark on the roof surface next to the large indicator 510 on the tape. The roofer then slides the tape up toward the apex of the roof until the first indicator 515 aligns with the single mark on the roof. The roofer then tacks the eyelet 130 to the roof to secure the tapes position and stretches out the tape to the apex of the roof. Alternative embodiment 500 is then used in the same manner as with the preferred embodiment. Each of the indicators 505, 510 & 515 on the tape are 5 1/2 inches apart from each other, and provide guides for striking chalk lines for each required row of shingles.
FIG. 6 is a top view of yet another alternative embodiment 600 of the present lay-out tape with the architectural side of the tape facing up. As with the preferred embodiment, indicators for standard shingles are provided on the back side of the tape. This embodiment provides the same useful purpose as the other embodiments however, this embodiment 600 can be used in fewer steps than previous embodiments. The first 2 inches 620 of the tape are calibrated with ¼ inch indicators to allow the roofer to measure the desired amount of overhang; usually 1 ¼ inches. Once the desired amount of tape is allowed to hang over the edge of the roof, the roofer immediately tacks down the tape, using eyelet 615, without the need to slide or move of the tape. The first row indicator 610 is 13 ¼ inches from the leading edge of the tape and is used to strike the chalk line for the row of shingles. Each subsequent indicator 605 is spaced 5 ½ inches apart and is used to strike subsequent chalk lines for subsequent rows of shingles. This embodiment 600 includes a traditional “L” shaped hook at the beginning of the tape to assist in pulling out the tape and to prevent the end of the tape from retracting into the case 105.
FIG. 7 shows two of the present lay-out tapes 100 in operation, on the roof 700 of a house. The first indicator 300 of each tape 100 is positioned approximately 12 inches from the bottom of the roof so that when the first row of shingles are added to the roof, the shingles will overhang the roof by approximately 1 ¼ inches. Nails are used to tack down the eyelets 130 on each tape and the tapes are then stretched over the apex of the roof. A chalk line is then stretched horizontally across the roof, using the first indicators 300 on the lay-out tapes for alignment and the first chalk line 710 is struck. This process is then repeated to strike the remaining chalk lines 705 using the remaining indicators 305 for alignment. This invention completely eliminates the time consuming and error prone requirement of having to manually pre-mark the roof surface with alignment marks.
The present lay-out tape has been shown above in several embodiments, each having their own beneficial features. Applicant acknowledges that the illustrated features could be combined in different ways to come up with even more embodiments and the figures are not intended to be limiting in any way.
The foregoing description of the specific embodiments will so fully reveal the general nature of the invention that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept. For example, spacing indicators for shingles other than architectural and standard shingles could be provided on the lay-out tape. The lay-out tape could also provide spacing indicia for other types of roofing materials, such as ceramic tiles. Therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology of terminology employed herein is for the purpose of description and not of limitation.
