DETAILED DESCRIPTION
(26) Prior to discussing the various embodiments, a review of the definitions of some exemplary terms used throughout the disclosure is appropriate. Both singular and plural forms of all terms fall within each meaning.
(27) As described herein, when one or more components are described as being connected, joined, affixed, coupled, attached, or otherwise interconnected, such interconnection may be direct as between the components or may be indirect such as through the use of one or more intermediary components. Also as described herein, reference to a member, component, or portion shall not be limited to a single structural member, component, or element but can include an assembly of components, members, or elements. Also as described herein, the terms substantially and about are defined as at least close to (and includes) a given value or state (preferably within 10% of, more preferably within 1% of, and most preferably within 0.1% of).
(28) Referring now to
(29) Referring now to
(30) Typically, the measuring and cutting of offset shingles is done manually by the installer of the roof. Straight cuts are difficult to make when up on a rooftop, so many installers will cut the shingles at a cutting station at the ground level to achieve a straight cut. This results in multiple trips up and down a ladder to measure and cut the shingles during installation. In some cases, to avoid trips up and down the ladder, an installer may install full width shingles and let them hang over the rake edge of the roof, cutting the excess shingle material off after a number of courses have been completed. Cutting after installation can damage the edge of the roof, and results in excess material falling to the ground that needs to be cleaned up and is typically wasted. Applicant has appreciated the need for prefabricated offset shingles that can be easily formed out of full width shingles without cutting or measuring to increase the speed and accuracy of installing offset courses of shingles on a rooftop.
(31) Referring now to
(32) The cuts 310 are spaced apart to form a first offset portion 316 having a width A, a second offset portion 318 having a width B, and a third offset portion 320 having a width C. In the illustrated embodiment, width A is one-sixth of the width of the full width shingle 300, width B is one-third (two-sixths) of the width of the full width shingle 300, and width C is one-half (three-sixths) of the width of the full width shingle 300. In some embodiments, the shingle 300 has a width of about 39 inches. In some embodiments, width A is about 6.5 inches, width B is about 13 inches, and width C is about 19.5 inches.
(33)
(34) The offset portions may also be described as steps as they form a stair-step pattern when the offset shingles are attached to the roof in descending size order, i.e., starting with the largest step or offset on the first course, then the next smallest step, then the next smallest, etc. In the embodiment illustrated in
(35) The formula to calculate the longest off-set shingle piece length, X.sub.L, is calculated in the following way. First, the total length L is defined as the sum of the step lengths, X.sub.L, X.sub.M, and X.sub.S, as shown by Equation 1, below.
L=X.sub.L+X.sub.M+X.sub.S(Equation 1)
(36) The relationship between the small and medium steps or offset portions can be defined in terms of the longest step and the offset length as follows:
X.sub.M=X.sub.LY(Equation 2); and
X.sub.S=X.sub.L2Y(Equation 3).
(37) These relationships are then substituted into Equation 1 which can be solved for X.sub.L, thereby defining X.sub.L in terms of L and Y, which are known values:
L=X.sub.L+(X.sub.LY)+(X.sub.L2Y)
(38) Solving for X.sub.L shows that:
X.sub.L=L/3+Y
(39) The small and medium steps, X.sub.S and X.sub.M, can also be redefined in terms of L and Y by substituting this definition of X.sub.L into Equations 2 and 3 shown above.
X.sub.M=L/3; and
X.sub.S=L/3Y.

(41) Referring now to
(42) The two cuts 510 and lines of weakness 508 are spaced apart to form a first offset portion 516 having a width A, a second offset portion 518 having a width B, and a third offset portion 520 having a width C. In the illustrated embodiment, width A is one-sixth of the width of the full width shingle 500, width B is one-half (three-sixths) of the width of the full width shingle 500, and width C is one-third (two-sixths) of the width of the full width shingle 500. In some embodiments, the shingle 500 has a width of about 39 inches. In some embodiments, width A is about 6.5 inches, width B is about 19.5 inches, and width C is about 13 inches.
(43) While the widths of offset portions 516, 518, 520 are similar to the offset portions 316, 318, 320 of shingle 300, arranging the one-half width portion in the middle of the one-sixth and one-third width portions allows the installer to create offset shingles in each one-sixth width increment up to the full width of the shingle. This allows the offset amount per course of shingles to be the same for each course, as shown in
(44) TABLE-US-00001 TABLE 1 Offset Width Offset Portion Combinations A 2/6 C 3/6 B 4/6 A + B B + C
(45)
(46) Referring now to
(47) The three cuts 610 and lines of weakness 608 are spaced apart to form a first offset portion 616 having a width A, a second offset portion 618 having a width B, a third offset portion 620 having a width C, and a fourth offset portion 622 having a width D. Widths A and C are equal, and widths B and D are equal. In the illustrated embodiment, widths A and C are one-sixth of the width of the full width shingle 600, and widths B and D are one-third (two-sixths) of the width of the full width shingle 600. In some embodiments, the shingle 600 has a width of about 39 inches. In some embodiments, widths A and C are about 6.5 inches, and widths B and D are about 13 inches.
(48) Alternating the positions of the smaller and larger size shingles allows the installer to create offset shingles in each one-sixth width increment up to the full width of the shingle. This allows the offset amount per course of shingles to be the same for each course, as shown in
(49) TABLE-US-00002 TABLE 2 Offset Width Offset Portion Combinations A 2/6 D 3/6 A + B 4/6 A + B + C B + C + D

(51) Referring now to
(52) The cuts 710 are spaced apart to form a first offset portion 716 having a width A, a second offset portion 718 having a width B, a third offset portion 720 having a width C, and a fourth offset portion 721 having a width D. In the illustrated embodiment, width A is one-tenth of the width of the full width shingle 700, width B is one-fifth (two-tenths) of the width of the full width shingle 700, width C is three-tenths of the width of the full width shingle 700, and width D is two-fifths (four-tenths) of the width of the full width shingle 700. In some embodiments, the shingle 700 has a width of about 39 or 40 inches. In some embodiments, width A is about 4 inches, width B is about 8 inches, width C is about 12 inches, and width D is about 16 inches.

(56) The formula to calculate the longest off-set shingle piece length, X.sub.L, is calculated in the following way. First, the total length L is defined as the sum of the step lengths, X.sub.L, X.sub.M, and X.sub.S, as shown by Equation 1, below.
L=X.sub.A+X.sub.B+X.sub.C+X.sub.D(Equation 1)
(57) The relationship between the small and medium steps or offset portions can be defined in terms of the longest step and the offset length as follows:
X.sub.A=X.sub.D3Y(Equation 2);
X.sub.B=X.sub.D2Y(Equation 3); and
X.sub.C=X.sub.DY(Equation 4).
(58) These relationships are then substituted into Equation 1 which can be solved for X.sub.L, thereby defining X.sub.L in terms of L and Y, which are known values:
L=(X.sub.D3Y)+(X.sub.D2Y)+(X.sub.DY)+X.sub.D
(59) Solving for X.sub.D shows that:
X.sub.D=(L+6Y)/4
(60) The smaller steps, X.sub.A, X.sub.B, and X.sub.C, can also be redefined in terms of L and Y by substituting this definition of X.sub.D into Equations 2, 3, and 4 shown above.
X.sub.A=(L6Y)/4;
X.sub.B=(L2Y)/4; and
X.sub.C=(L+2Y)/4.
(61) While the prefabricated offset shingles 300, 500, 600, and 700 described above have offset portions of different widths, the offset portions may be the same width and be formed by cuts that are uniformly spaced across the width of the shingle. Furthermore, the different sized portions do not have to be multiples of the smallest portione.g., one-sixth of the width of the shingle. For example, a small offset portion may be 15 percent of the width of the full width shingle, a medium offset portion may be 35 percent of the width of a full width shingle, and a large offset portion may be 50 percent of the width of a full width shingle.
(62) The pre-cut prefabricated shingles illustrated by

(68) In the illustrated embodiment, the shingles 1000 are stacked on top of each other in alternating arrangements, similarly to the arrangements described and illustrated in
(69) In such an arrangement, the top face 1032 of the shingle assembly 1030 is the front surface 1016 of the top-most shingle 1030 in the shingle assembly 1030 and the bottom face 1034 of the shingle assembly 1030 is the front surface 1016 of the bottom-most shingle 1000 in the shingle assembly 1030. The front face 1036 of the shingle assembly 1030 includes the bottom edge 1012 of the bottom-most shingle 1000 and the top edge 1010 of the subsequent shingle 1000. The rear face 1038 of the shingle assembly 1030 includes the top edge 1010 of the bottom-most shingle 1000 and the bottom edge 1012 of the subsequent shingle 1000. The left side 1040 of the shingle assembly 1030 includes the first side edge 1002 of the bottom-most shingle 1000 and the second side edge 1004 of the subsequent shingle 1000, and the right side 1042 of the shingle assembly includes the second side edge 1004 of the bottom-most shingle and the first side edge 1002 of the subsequent shingle 1000. Additional shingles 1000 can be added in a similar manner to increase the size of the shingle assembly 1030.
(70) While the shingle assembly 1030 has been described as being composed of alternatingly oriented shingles 1000, it will be appreciated that the shingles 1000 may be arranged in the shingle assembly 1030 in any suitable manner. For example, in certain embodiments, such as where the shingles 1000 do not have a release tape or a sealant, or the release tape or shingle is in a different configuration, the shingles 1000 may be stacked with the front surface 1016 of each shingle 1000 oriented in the same direction such that the first side edge 1002, the second side edge 1004, the top edge 1010, and the bottom edge 1012 of each shingle 1000 in the shingle assembly 1030 are aligned with the first side edge 1002, the second side edge 1004, the top edge 1010, and the bottom edge 1012 of the other shingles 1000.
